As a conventional portable recording device, for example, as shown in Patent Document 1, the
shaft portion of the microphone main body is rotatably attached to the upper end of the main
body case accommodating the recording portion. The microphone body is provided with left and
right microphones on both sides of the shaft. Each microphone is comprised of a tubular
transducer chamber and a transducer housed therein. Each transducer is stored in an inclined
state. By rotating the microphone body, each transducer can be directed to the source.
[0003]
Since the portable recording device performs high-quality recording, it has a high-performance
recording mechanism consisting of a microphone and a recording unit, but does not have a
camera mechanism. By the way, although a mobile phone as shown in Patent Document 2, a
digital camera capable of shooting moving pictures, and a video camera have an image recording
as a main function, they have a recording mechanism in addition to a camera mechanism, and an
image and sound. Both have been recorded.
[0004]
For example, in the mobile phone described in Patent Document 2, a second housing having an
operation button is slidable with respect to a first housing having a display screen. A rotating
body is rotatably attached to the end of the second housing. A camera unit and a microphone
unit are built in the rotating body. Further, on the surface of the rotating body, the
photographing window of the camera unit and the sound collection port of the microphone unit
are arranged to face in the same direction.

However, in Patent Document 2, the microphone unit including the transducer is disposed only
on the left side of the camera module, and the rotating body has no space for disposing the
transducer on each of the left and right sides of the camera module. For this reason, it becomes a
monaural recording by one transducer, and can not perform high quality recording.
[0007]
Further, in Patent Document 2, the camera unit and the microphone unit are disposed in the
same space, and the signal line for the image signal and the signal line for the audio signal are
drawn from the same position of the rotating body, so the image signal And the audio signal may
interfere with each other to generate noise.

unit, cylindrical left and right transducer chambers located on both sides of the camera housing,
and attached to both sides of the camera housing; Left and right support arms respectively
projecting into the left and right transducer chambers, and left and right transducers supported
by the respective support arms and rotated together with the camera module to convert audio
from a scene for recording by the recording unit into audio signals , And.
[0010]
The image flexible wiring sheet is drawn out from one side of the camera housing and connected
to the recording unit and transmits an image signal captured by the camera module, and drawn
out from the other side of the camera housing. And an audio flexible wiring sheet that is
connected to the recording unit and transmits an audio signal converted by each of the
transducers.

In addition, as said each flexible wiring sheet, FPC (Flexible Printed Circuit), FFC (Flexible Flat
Cable), etc. are mentioned.
[0011]
Furthermore, it is preferable that the flexible wiring sheets are connected to the recording unit
and the recording unit after being drawn out of the camera housing and wound in an arc shape.
[0012]
Further, it is preferable that a plurality of claws for supporting each of the transducers are
formed at the tip of each of the support arms, and the transducers are accommodated in the
respective transducer chambers while maintaining a space around them.
[0013]

left and right transducing chambers, and the left and right support arms hold the left and right
transducers for converting audio into audio signals, so both recording and stereo recording can
be performed. In addition, the camera and microphone can be rotated together towards the
scene.
[0017]
Further, since the flexible wiring sheet for transmitting the image signal and the flexible wiring
sheet for transmitting the audio signal are pulled out from both sides of the camera housing, the
two are separated, so that the generation of noise due to the interference of the signal can be
prevented. .
[0018]
Furthermore, by supporting each transducer by a plurality of claws formed at the tip of each
support arm, the transducer is rotatably disposed in the cylindrical transducer chamber, and a
space is secured around the transducer, so that the microphone The directivity can be improved.

control unit 141 as the still image data in the SD card 142 which is detachably housed inside the
main body case 3. In the moving image shooting mode, audio signals from the left and right
microphones 4 and 5 and an image signal from the camera 6 are recorded by the recording /
reproduction control unit 141 in the SD card 142 as a moving image file including image data
and audio data. In the recording mode, audio signals from the left and right microphones 4 and 5
are recorded on the SD card 142 as audio data by the recording / reproduction control unit 141.
[0059]
The control board 128 also includes an audio A / D converter 144 for converting an analog

Next, the operation of the above embodiment will be described. When moving picture shooting is
performed by the camera-equipped portable recording device 2, the mode switching button 26 is
operated to set the moving picture shooting mode. The camera 6 rotates the camera housing 14
so as to face the scene to be photographed. When the camera housing 14 is rotated, the click
piece 124 elastically deforms, and the click claw 123 gets out of the click recess 122 and the
fixing is released (see FIG. 13). When the camera 6 is rotated to a position where the click claw
123 faces the click recess 122, the click piece 124 returns to its original shape (elastic
deformation), and the click claw 123 is fitted into the click recess 122. In order to release the
fixation of the camera housing 14, a relatively large force is required, and under normal use, the
fixation of the camera housing 14 is not released even if vibration is applied.
[0062]
The relay substrate 65 also rotates while the camera housing 14 is rotating. Since the loops of
the audio FFC 83 and the image FPC 84 arranged on the left and right of the camera housing 14
are slackened or tightened in response to the rotation, the camera housing 14 rotates smoothly
without being caught.
[0063]
The rotation of the camera housing 14 integrally rotates the camera module 64 in the camera
housing 14, the left support arm 55 and the right support arm 56. By this rotation, the imaging
window 63 is adjusted to the scene, and the left and right transducers 47 and 50 supported by
the left and right support arms 55 and 56 are adjusted to be inclined 45 ° with respect to the
scene.

[0064]
When the camera 6 is rotated from the position facing forward to the position facing upward, the
detection switch 125 is turned on by the switch projection 108 a of the right shaft plate 108, and
the detection switch 125 outputs a detection signal to the recording / reproduction control unit
141. It is input. When the detection signal is input, the recording / reproduction control unit 141
rotates the image by 180 ° from the state captured by the CMOS 66 to turn it upside down. In
addition, when the camera 6 is rotated from the position facing rearward to the position facing
upward, the detection switch 125 is turned off by the switch projection 108a, and the input of
the detection signal is stopped. The recording / reproduction control unit 141 stops the image
inversion when the input of the detection signal is stopped.
[0065]
In the movie shooting mode, since the camera module 64 is operating, the CMOS 66 shoots a
scene and outputs an image signal. The image signal is input to the CMOS AFE 132 of the relay
substrate 65 through the FPC 70. The input image signal is amplified, sampled and A / D
converted by the CMOS AFE 132, and then sent as a digital signal to the control substrate 128
through the image FPC 84.
[0066]
Also, the sound from the scene passes through the sound collecting openings 46a and 49a and
the sound collecting holes 48a and enters the left and right transducing chambers 46 and 49.
These sounds are converted into audio signals by the left and right transducers 47 and 50, and
are input to the audio A / D converter 144 of the control substrate 128 via the connection wires
81 and 82, the relay substrate 65, and the audio FFC 83. The audio A / D converter 144 converts
an audio signal input via the audio FFC 83 into a digital signal. Since the audio FFC 83 is
separated from the image FPC 84, noise generation due to interference between the audio signal
and the image signal is prevented. In addition, since a space is secured around the left and right
transducers 47 and 50, in particular, in the rear, high-quality audio signals can be obtained
without receiving echo from the rear.

image signal and sends it to the LCD 21 through the display control unit 147. A through image
for monitoring is displayed on the LCD 21.
[0068]
After the scene is confirmed on the LCD 21, the shooting / recording button 22 is pressed to
start moving image shooting. During the moving image shooting, the image DSP 145 performs
high-accuracy image processing on the digital image signal, and the audio DSP 146 performs
various signal processing on the digital audio signal. The recording / reproduction control unit
141 generates a moving image file including image data and audio data from the digital signal
subjected to the signal processing, and records the moving image file on the SD card 142. Even
during the moving image shooting, the already-captured image is displayed on the LCD 21.
[0069]
In the still image shooting mode, only the camera mechanism is activated and the recording
mechanism is not activated. When the shooting / recording button 22 is pressed in the still
image shooting mode, the recording / reproduction control unit 141 records the digital image
signal subjected to the image processing by the image DSP 145 in the SD card 142 as still image
data. Note that, even in the still image shooting mode, a through image for monitoring is
displayed on the LCD 21.
[0070]
In the recording mode, only the recording mechanism is activated and the camera mechanism is
not activated. When the photographing / recording button 22 is pressed, the recording /
reproducing control unit 141 records the digital audio signal subjected to the signal processing
by the audio DSP 146 in the SD card 142 as audio data.
