The intelligent electronic payment terminal 900 having a sound source as shown in FIG. 11 is
usually provided with an opening 930 so that the customer can easily hear the sound emitted
from the electronic payment terminal 900. Toward the customer at the checkout counter.
However, when the electronic payment terminal 900 is installed in this way, the clerk in front of
the customer across the cashier is positioned in the opposite direction to the direction in which
the sound is emitted from the opening 930. Therefore, there is a problem that it is difficult to
hear the sound emitted from the electronic settlement terminal 900.
[0007]
On the other hand, according to the speakerphone structure for telephones described in Patent
Document 1, the radiation sound emitted from the speaker is reflected by the downward conical
360 ° omnidirectional reflector, It is omnidirectionally diffused in all directions of radiation
through the sound holes. When this structure is adopted for the electronic settlement terminal,
the sound emitted from the electronic settlement terminal can be made easily audible to both the
customer and the clerk. However, according to this structure, the radiation sound emitted from
the speaker is reflected by the conical 360 ° omnidirectional reflector, but the sound is not
transmitted over the entire surface in the direction in which the reflected sound travels. There is
no hole. Therefore, according to this structure, the radiation sound emitted from the speaker is
reflected by the conical 360 ° omnidirectional reflector, but a part thereof is the wall of the
housing where no sound hole is provided. It is reflected in the part and echoes. As a result, there
is a problem that the sound emitted from the sound hole becomes a muffled sound. Further, in
the case where the housing is made of a material having high sound absorption, there is a
problem that the sound hitting the wall of the housing is absorbed, and the sound emitted from
the sound hole is reduced.

such that the sound radiation surface is in contact with the plurality of holes 160. The speaker
120 may be an example of the “sound source” in the present invention.
[0020]
Further, on the upper surface of the lower wall 110c of the lower housing 110, a sound
reflecting portion 140 for reflecting the sound radiated from the speaker 120 toward the side
wall 110b of the lower housing 110 is provided. Specifically, the sound reflection unit 140 is

which the respective pyramidal faces 140a to 140d of the sound reflection unit 140 are directed.
[0022]
FIG. 4 shows the traveling direction of the sound in the electronic settlement terminal 100.
Specifically, the arrows in FIG. 4 indicate the traveling direction of the sound. With the
configuration as described above, the sound emitted from the speaker 120 passes through the
plurality of holes 160 and is emitted to the inside of the lower housing 110. Then, the sound
radiated to the inside of the lower housing 110 is reflected in the direction of the openings 130
a-d provided in the side wall 110 b of the lower housing 110 by the pyramid faces 140 a-d of the
sound reflecting portion 140. . And the sound reflected by each pyramid surface 140 ad of the
sound reflection part 140 is discharge | released to the exterior of the lower housing | casing
110 from each opening part 130 ad. As described above, the sound emitted from the speaker
120 is not reflected in the direction in which the openings 130 a to 130 d in the side wall 110
inside the lower housing 110 are not provided. Therefore, in this configuration, since the sound
03-05-2019

is not reflected so much inside the side wall 110 inside the lower housing 110, a clear sound can
be emitted from each of the openings 130a to 130d without stagnation.
[0023]
Further, for example, the electronic settlement terminal 100 is installed at a counter of a store or
a restaurant. It is assumed that there is a clerk of a shop or restaurant on one side of the counter
and a customer on the other side of the counter. At this time, when the electronic settlement
terminal 100 is installed with the opening 130 c facing the store clerk, the sound emitted from
the opening 130 c is easily transmitted to the store clerk. Also, in this case, the sound emitted
from the opening 130a is transmitted to the customer on the opposite side of the store clerk in
an easy-to-hear manner.
[0024]
Further, in the above configuration, the speaker 120 is not provided inside the lower housing
110. Therefore, in the above configuration, even if water intrudes into the lower housing 110
from the openings 130a to 130d, there is no risk of the speaker 120 being submerged.
Therefore, in the electronic settlement terminal 100 configured as described above, the openings
130a to 130d of the lower housing 110 do not need to be drip-proofed.
[0025]
Further, in the above configuration, preferably, the size of the sound reflecting portion 140 is
such that the size of the bottom surface is equal to or larger than the size of the sound radiation
surface of the speaker 120. With such a configuration, the sound emitted from the speaker 120
is not vertically reflected or absorbed by the lower wall 110 c of the lower housing 110 in which
the sound reflecting unit 140 is not provided. . Therefore, the sound radiated from the speaker
120 is more efficiently reflected in the directions of the openings 130a to 130d.
[0026]
In the above configuration, preferably, the length in the circumferential direction (horizontal
03-05-2019
8
direction) of each of the openings 130a to 130d is equal to or greater than the length of the base
of the opposing pyramidal surfaces 140a to 140d. In addition, preferably, the length in the
direction (vertical direction) orthogonal to the circumferential direction of each opening 130 is
equal to or greater than the height of the sound reflecting portion 140. With such a
configuration, the size of the opening portion of each of the openings 130a to 130d becomes
larger than the size of the horizontal view of each of the pyramid faces 140a to 140d. Therefore,
the sound reflected by each of the pyramidal surfaces 140a to 140d is emitted from the openings
130a to 130d to the outside of the lower housing 110 with almost no reflection inside the side
wall 110b of the lower housing 110. Become.
[0027]
FIG. 5 shows an example of the configuration of the electronic settlement terminal 200 according
to another example of the embodiment of the present invention. FIG. 6 shows a CC cross section
of the electronic settlement terminal 200. FIG. 7 shows a DD cross section of the electronic
settlement terminal 200.
[0028]
The configuration of the electronic settlement terminal 200 differs from the electronic settlement
terminal 100 described above in the shape of the sound reflection unit 240. The configuration
other than the sound reflection unit 240 in the electronic payment terminal 200 is the same as
that of the electronic payment terminal 100 described above, and thus the specific description
thereof will be omitted.
[0029]
The shape of the above-mentioned sound reflection part 140 is making the shape of a general
pyramid. On the other hand, the shape of the sound reflection part 240 is making the pyramid
shape which each pyramid surface 240 ad curves in concave shape. With such a configuration,
the sound emitted from the speaker 220 is more positively guided toward the openings 130 a-d
provided in the side wall 210 b of the lower housing 210. It will be reflected by the pyramidal
faces 240a-d.

[0030]
FIG. 8 shows an example of the configuration of the electronic settlement terminal 300 according
to still another example of the embodiment of the present invention. FIG. 9 shows an EE cross
section of the electronic settlement terminal 300. FIG. 10 shows an FF cross section of the
electronic settlement terminal 300.
[0031]
The electronic settlement terminal 300 differs from the electronic settlement terminal 100 in the
shape of the sound reflecting unit 340. The configuration other than the sound reflection unit
340 in the electronic settlement terminal 300 is the same as that of the electronic settlement
terminal 100 described above, and thus the specific description thereof will be omitted.
[0032]
The above-mentioned sound reflection part 140 is locally provided in the lower wall 110 c of the
lower housing 110 at a position facing the speaker 120. On the other hand, the sound reflecting
portion 340 is formed over the entire surface of the lower wall 310 c of the lower housing 310.
With this configuration, the sound emitted from the speaker 120 is not vertically reflected or
absorbed by the lower wall 310 c of the lower housing 310. Therefore, the sound reflected by
each pyramid surface 340 a-d is more efficiently emitted from the openings 330 a-d to the
outside of the lower housing 310.
[0033]
As mentioned above, although this invention was demonstrated using embodiment, the technical
scope of this invention is not limited to the range as described in said embodiment. Various
changes or improvements can be added to the above embodiment. It is also apparent from the
scope of the claims that the embodiments added with such alterations or improvements can be
included in the technical scope of the present invention.
