[0034]
When this card is issued, the arithmetic control circuit 49 opens the entrance electric gate 5 and
operates the electric shutter 10 of the garage 6 corresponding to the garage number of the
organizing card to open the shutter 11, and the illumination lamp 22 in the garage 6 Turn on.
The electric shutter 10 can be opened and closed by a shutter open / close switch (not shown) in
the garage 6 or a manual operation from a control room (not shown).
[0035]
In this state, when the occupant of the car 14 receives the arrangement card and inserts the car
14 into the garage 6 of the reference number as shown in (d) of FIG. The signals are sequentially
detected by the sensors 20 and 19, and detection signals from the two sensors 20 and 19 are
sequentially input to the arithmetic control circuit 49.
[0036]
The arithmetic control circuit 49 receives the detection signals from the two sensors 20 and 19
to confirm that the automobile 14 is completely in the garage 6 and operates the electric shutter
10 of the garage 6 to operate the shutter 11. Close
As a result, the inside of the garage 6 becomes an enclosed room 13.
At the same time, the arithmetic control circuit 49 operates the air conditioner 25 to ventilate
and adjust the temperature in the closed chamber 13 and operates the electric screen 26 to
extend the projection screen 29 downward.
[0037]
Next, the arithmetic control circuit 49 operates the AV controller 50 to cause the image
projection device 31 to project video such as video, television, BS broadcast, CS broadcast, game,
karaoke and the like on the projection screen 29. At this time, the arithmetic control circuit 49

causes the speakers 32 to 35 to output stereo sound synchronized with the video, and generates
a deep bass from the subwoofer 47 to directly vibrate the vehicle body of the automobile 14 and
thereby the occupant of the seat in the vehicle compartment. Convey heavy bass vibration to In
this case, the windows 14b, 14d, 14g and 14i of the car are kept open for this screening.
[0038]
It should be noted that prior to the screening of the video, television, BS broadcast, CS broadcast,
game, karaoke, etc., the information such as the method of screening operation by the AV handheld device 48, the guidance in the hall, the emergency countermeasure is projected At the same
time as it is projected on the screen 29, it is announced from the speakers 32 to 34.
[0039]
As a result, the passenger in the car 14 can view the image on the projection screen 29 in a state
of being realistically filled with sound and vibration.
[0040]
When viewing such an image, the arithmetic control circuit 49 always receives signals from the
CO 2 sensor 23 and the CO sensor 24, and if the engine of the automobile 14 continues to
operate erroneously, the CO 2 gas in the closed chamber 13 or When harmful gases such as CO
gas exceed safe standard levels and the signals from CO2 sensor 23 and CO sensor 24 exceed a
certain level, a warning sound or warning announcement indicating that it is dangerous is output
from the speakers 32-35. The image projection apparatus 31 projects a danger or the like on the
projection screen 29 and operates the electric shutter 10 to open the shutter 11.
In this case, the AV controller 50, the speakers 32 to 35, the image projection device 31, the
electric screen 26 and the like constitute warning means.
[0041]
In this way, after viewing is finished, the management room is notified of the exit by an
interphone or the like (not shown) in the garage 6, and the controller operates the electric
shutter 10 to open the shutter 11.
[0042]
10-05-2019

At this time, even if the arithmetic control circuit 49 lights the green bulb (not shown) in the
illumination lamp 22 when the shutter 11 is completely opened, the automobile 14 is held on the
shutter 11 even if the automobile 14 leaves the garage 6. Inform that there is no collision (safety
condition).
[0043]
After this, when the passenger advances the automobile 14 to the outlet 2 side as shown in FIG.
7B (b) and pays the usage fee with the automatic settlement machine 7, the arithmetic control
circuit 49 opens the outlet electric gate 8 and exits. Make it possible.
[0044]
Although the example demonstrated above demonstrated the case where it utilized by a motor
vehicle, this invention is not necessarily limited to this.
For example, by providing a body having a seat on which the spectator is seated and receiving a
deep bass, a part of the body is opened, and the body is supported on the floor by elastic
supporting means such as a plurality of springs. Even when the floor is made of concrete or the
like which hardly transmits deep bass, vibrations due to the deep bass can be transmitted to the
audience to reproduce the sense of presence.
[0045]
Since the present invention is configured as described above, it is possible to enjoy a realistic
sound.
[0046]
Further, by using the system of the present invention in a vehicle such as a car, it is possible to
perform realistic sound reproduction without the need for a special device on the vehicle side.
[0047]
Furthermore, by providing an air conditioner and performing acoustic reproduction in a closed
room, the sense of reality can be improved in a safe state.
