The lower right cover 36 of the operation portion as the seat mounting portion is made of resin. The lower right cover 36 of the operation unit is fixed to a fixed base (not shown) fixed to the image reading unit 6, and covers the lower side of the operation unit 11 and the top surface of the vertical path portion cover 10. The lower right cover 36 of the operation unit is preferably made of a color having a brightness of L = 80 or more. The lower right cover 36 of the operation unit is made of an opaque resin (for example, a white resin) having a thickness of about 2 mm.

The lower right cover 36 of the operation unit is formed with holes 36b1 to 36b5 as first holes penetrating in the vertical direction (see FIG. 4). The holes 36b1 to 36b5 are provided at positions facing the lamps 61a at different positions, corresponding to the fact that the positions of the lamps 61a in the IC card reader 61, which will be described later, differ depending on the type of the IC card reader 61.

For example, the holes 36b1 to 36b3 correspond to the positions of the lamps of the IC card reader manufactured by NTware. Further, the hole portion 36b4 corresponds to the position of the lamp of the IC card reader manufactured by saxa, and the hole portion 36b5 corresponds to the position of the lamp of the IC card reader manufactured by Toppan Forms. As described above, the holes 36b1 to 36b5 are provided so as to correspond to the positions of the lamps of various types of IC card readers.

A lamp 61a as a light emitting unit is provided. The LED and the lamp 61a are provided at different positions depending on the type of the IC card reader 61. For example, the lamp 61a lights up in green when the information on the IC card is read normally, and lights up in red when the information on the IC card is not read normally. The IC card reader 61 is covered with a sheet material 36a. The IC card reader 61 is electrically connected to the apparatus main body 3 by a cable 62 and a connector 63.

<Composition of sheet material>
The configuration of the sheet material 36a according to the first embodiment of the present invention will be described in detail with reference to FIG.

The sheet material 36a includes a transparent sheet 36a1, a semitransparent printing layer 36a2, a transmission prevention printing layer 36a3, and a double-sided tape 36a4.

The transparent sheet 36a1 as the first transparent sheet is transparent and is made of, for example, a polycarbonate material having a thickness of 0.5 mm.

The translucent printing layer 36a2 as the translucent portion is printed on the lower surface of the transparent sheet 36a1. The translucent print layer 36a2 is translucent, and the entire surface is formed of the same color with no difference in transparency and color.

Specifically, the translucent print layer 36a2 preferably has a transmittance of more than 5% and less than 25% in a region of 400 mm to 700 mm in which the wavelength of light is visible light, for example, the transmittance is 10. Set to%. When the transmittance of the semitransparent printing layer 36a2 is 5% or less, the light transmitted by the lamp 61a of the IC card reader 61 is small, so that the semitransparent printing layer 36a2 has poor visibility from the outside. Further, when the translucency of the semitransparent print layer 36a2 is 25% or more, light is transmitted too much and the hole portion 36b can be visually recognized from the outside, so that the design property is impaired.

The translucent print layer 36a2 is preferably composed of a color having a lightness of L = 80 or more, and for example, the lightness L is set to about 85. In the semitransparent print layer 36a2, the chromaticity a indicating the hue and saturation is set to about -1 to 0, and the chromaticity b is set to about 0 to 1, so that the chromaticity is set to a number close to white. There is. Here, the chromaticity a and b indicate the direction of the color, the chromaticity a indicates the red direction, the chromaticity-a indicates the green direction, the chromaticity b indicates the yellow direction, and the chromaticity-b indicates the blue direction. ing.

The transmission prevention printing layer 36a3 as the transmission prevention portion is printed on the lower surface of the semitransparent printing layer 36a2 to prevent light transmission. The transmission prevention printing layer 36a3 is formed of silver or black having a transmittance of 1% or less in a region of 400 mm to 700 mm in which the wavelength of light is visible light. The transmission prevention printing layer 36a3 is formed with holes 36b6 to 36b8 as second holes penetrating in the vertical direction at positions facing the holes 36b1 to 36b5 provided in the lower right cover 36 of the operation unit. The inner diameter a of the holes 36b6 to 36b8 of the transmission prevention printing layer 36a3 is smaller than the inner diameter b of the holes 36b1 to 36b3 of the lower right cover 36 of the operation portion (a <b). Specifically, the inner diameter a is φ6 mm and the inner diameter b is φ8 mm.

The double-sided tape 36a4 fixes the transmission prevention printing layer 36a3 to the lower right cover 36 of the operation portion at the position of the outer peripheral end portion of the sheet material 36a that does not overlap with the holes 36b1 to 36b3 in the vertical direction.

<Operation of reader>
The operation of the reading device 200 according to the first embodiment of the present invention will be described in detail with reference to FIGS. 5 to 7.

Although the description of the holes 36b4 and 36b5 is omitted in the description using FIGS. 5 to 7, the holes 36b4 and 36b5 are the same as the holes 36b1 to 36b3. Further, in the description using FIGS. 5 to 7, the description of the holes facing the holes 36b4 and 36b5 in the transmission prevention printing layer 36a3 is omitted, but the holes facing the holes 36b4 and 36b5 are also shown. It is the same as 36b6 to 36b8.

In FIGS. 5 to 7, an IC card reader 61 having a lamp 61a at the position of the hole 36b1 will be described as an example. The operation of the reading device 200 when the lamp 61a is provided in any of the holes 36b2 to 36b5 is the same as the operation of the reading device 200 when the lamp 61a is provided at the position of the hole 36b1.

First, the operation of the reading device 200 when the lamp 61a is turned off will be described in detail with reference to FIGS. 5 and 6.

When the user U sees the area without the holes 36b1 to 36b3 of the lower right cover 36 of the operation unit and the holes 36b6 to 36b8 of the transmission prevention printing layer 36a3 from above, as shown by an arrow C in FIG. The light reflected from the translucent printing layer 36a2 of the sheet material 36a is visually recognized. As a result, the user U recognizes the white color.

Further, when the user U sees the region having the holes 36b1 to 36b3 and the holes 36b6 to 36b8 from above, the user U visually recognizes the light reflected from the translucent printing layer 36a2 as shown by the arrow D in FIG. Will be done. At this time, the transmitted light that has passed through the translucent printing layer 36a2 is absorbed because the inside and the bottom of the holes 36b6 to 36b8 and the holes 36b1 to 36b3 are darkened and does not reach the user U. From this, the user U visually recognizes the light reflected from the entire surface of the translucent print layer 36a2 regardless of the presence or absence of the holes 36b1 to 36b3 and the holes 36b6 to 36b8. Therefore, the user U recognizes that the colors of the regions with the holes 36b1 to 36b3 and the holes 36b6 to 36b8 and the regions without the holes 36b6 to 36b8 are substantially the same.

At this time, by configuring the lower right cover 36 of the operation unit and the semitransparent printing layer 36a2 with a color having a brightness of L = 80 or more, light can be reliably reflected. Further, by setting the transmittance of the light wavelength of the transmission prevention printing layer 36a3 in the region of 400 mm to 700 mm, which is visible light, to 1% or less, the light transmitted through the translucent printing layer 36a2 is surely shielded and absorbed. Can be done.

Here, a case where the transmission prevention print layer 36a3 is not provided will be described with reference to FIG. In FIG. 6, when the area where the holes 36b1 to 36b3 are located is viewed from above, the user U visually recognizes the light reflected from the translucent print layer 36a2 as shown by the arrow D in FIG. ..

Further, when the user U sees the region without the holes 36b1 to 36b3 from above, the user U visually recognizes the light reflected by the translucent print layer 36a2 as shown by the arrow E in FIG. On the other hand, the transmitted light that has passed through the semitransparent printing layer 36a2 is reflected on the top surface of the lower right cover 36 of the operation unit, passes through the semitransparent printing layer 36a2 again, and is visually recognized by the user U. As a result, the user U feels as if there is a light source on the back surface of the sheet material 36a, and recognizes that the region without the holes 36b1 to 36b3 is brighter than the region with the holes 36b1 to 36b3. Therefore, there is a difference in brightness between the region with the holes 36b1 to 36b3 and the region without the holes 36b1 to 36b3, which impairs the appearance.

In order to reliably prevent such reflection of light by the lower right cover 36 of the operation portion, as shown in FIG. 5B, the lower right cover 36 of the operation portion is larger than the inner diameter a of the holes 36b6 to 36b8 of the transmission prevention printing layer 36a3. The inner diameter b of the holes 36b1 to 36b3 is increased (a <b). As a result, it is possible to reliably prevent light from being reflected by the upper surface of the lower right cover 36 of the operation unit. Such a configuration is particularly necessary when the lower right cover 36 of the operation unit has a color such as white that reflects light.

Next, the operation of the reading device 200 when the lamp 61a is lit will be described in detail with reference to FIG. 7.

The light of the lamp 61a passes through the hole portion 36b1 and is transmitted to the outside through the semitransparent printing layer 36a2 and the transparent sheet 36a1 of the transparent material. At this time, since the translucent print layer 36a2 transmits light with a transmittance of about 10%, the user U can visually recognize the light emitted from the lamp 61a when viewed from above.

As described above, when the lamp 61a is turned off, the user U cannot see the color difference between the area with the holes 36b1 to 36b3 and the area with the holes 36b6 to 36b8 and the area without the holes 36b1 to 36b3. And the presence of holes 36b6 to 36b8 cannot be visually recognized. As a result, the user U sees the sheet material 36a as having a uniform color when viewed from above. Therefore, even if the plurality of holes 36b1 to 36b3 and the holes 36b6 to 36b8 are provided, it is possible to prevent erroneous recognition of the lamp 61a due to the holes 36b1 to 36b3 and the holes 36b6 to 36b8 being visible. Further, when the lamp 61a is lit, the user U can visually recognize the light emitted from the lamp 61a.

Further, it is not necessary to prepare a sheet without a print layer corresponding to the position of the lamp 61a of the IC card reader 61 according to the position of the lamp 61a, and one sheet can be used to reduce the cost. can do. Further, since it is not necessary to distinguish the sheet material 36a to be attached to the lower right cover 36 of the operation unit at the time of assembling, the assembling can be simplified and the assembling property can be improved.

Further, by forming the translucent printing layer 36a2 by printing on the transparent sheet 36a1, the transparent sheet 36a1 can be made cheaper than the case where the transparent sheet includes the translucent portion.

In the present embodiment, the lower right cover 36 of the operation unit is provided above the lamp 61a and has a hole 36b1 facing the lamp 61a. Further, it is provided above the lower right cover 36 of the operation unit, has a hole 36b6 at a position corresponding to the hole 36b1, and has a transmission prevention printing layer 36a3 that blocks light. Further, the translucent printing layer 36a2 is provided above the transmission prevention printing layer 36a3 and has no difference in transparency and color between the region facing the hole 36b6 and the region other than the facing region. As a result, the light of the light emitting portion can be transmitted to the outside without deteriorating the design.

In the present embodiment, the translucent printing layer 36a3 is provided by printing on the lower surface of the translucent printing layer 36a2. It may be provided below the layer 36a2.

Further, in the present embodiment, the operation portion lower right cover 36 is provided with a plurality of holes 36b1 to 36b5, and the transmission prevention printing layer 36a3 is provided with a plurality of holes 36b6 to 36b8. A single hole may be provided in each of the print layers.

From this, the user U visually recognizes the light reflected from the entire surface of the translucent print layer 36a2 regardless of the presence or absence of the holes 36b1 to 36b3 and the holes 36b9 to 36b11. Therefore, the user U recognizes that the colors of the regions with the holes 36b1 to 36b3 and the holes 36b9 to 36b11 and the regions without the holes 36b9 to 36b11 are substantially the same.

Next, the operation of the reading device 300 when the lamp 61a is lit will be described in detail with reference to FIG.

The light of the lamp 61a passes through the hole 36b1 and passes through the transparent sheet 36c1, and also passes through the hole 36b10 and passes through the translucent printing layer 36a2 and the transparent sheet 36a1 of the transparent material to be irradiated to the outside. At this time, the user U is irradiated from the lamp 61a when viewed from above because the transparent sheet 36c1 and the transparent sheet 36a1 are transparent and the translucent printing layer 36a2 transmits light with a transmittance of about 10%. The light is visible.

As described above, when the lamp 61a is turned off, the user U cannot see the color difference between the area with the holes 36b1 to 36b3 and the area with the holes 36b9 to 36b11 and the area without the holes 36b1 to 36b3. And the presence of the holes 36b9 to 36b11 cannot be visually recognized. As a result, the user U sees the sheet material 36e as having a uniform color when viewed from above. Therefore, even if the plurality of holes 36b1 to 36b3 and the holes 36b9 to 36b11 are provided, it is possible to prevent erroneous recognition of the lamp 61a due to the holes 36b1 to 36b3 and the holes 36b9 to 36b11 being visible. Further, when the lamp 61a is lit, the user U can visually recognize the light emitted from the lamp 61a.

Further, it is not necessary to prepare a sheet without a print layer corresponding to the position of the lamp 61a of the IC card reader 61 according to the position of the lamp 61a, and one sheet can be used to reduce the cost. can do. Further, since it is not necessary to distinguish the sheet material 36e to be attached to the lower right cover 36 of the operation unit at the time of assembling, the assembling can be simplified and the assembling property can be improved.

Further, by providing the transparent sheet 36c1 between the transmission prevention printing layer 36c2 and the lower right cover 36 of the operation portion, the transparent sheet 36c1 can be made cheaper as compared with the case where the transparency prevention portion is included in the transparent sheet.

In the present embodiment, the lower right cover 36 of the operation unit is provided above the lamp 61a and has a hole 36b1 facing the lamp 61a. Further, it is provided above the lower right cover 36 of the operation unit, has a hole 36b9 at a position corresponding to the hole 36b1, and has a transmission prevention printing layer 36c2 that blocks light. Further, the translucent printing layer 36a2 is provided above the transmission prevention printing layer 36c2 and has no difference in transparency and color between the region facing the hole 36b9 and the region other than the facing region. As a result, the light of the light emitting portion can be transmitted to the outside without deteriorating the design.

In the present embodiment, the transparent sheet 36c1 is printed on the upper surface of the transparent sheet 36c1 to provide the transmission prevention printing layer 36c2. However, a transmission prevention printing sheet separate from the transparent sheet 36c1 is provided above the transparent sheet 36c1 as a transmission prevention portion. You may.

Further, in the present embodiment, the operation portion lower right cover 36 is provided with a plurality of holes 36b1 to 36b5, and the transmission prevention printing layer 36c2 is provided with a plurality of holes 36b9 to 36b11. A single hole may be provided in each of the print layers.

(Other embodiments)
In the first and second embodiments described above, two layers of the transparent sheet 36a1 and the translucent printing layer 36a2 are provided, but instead of this, one transparent sheet containing the translucent material is provided. May be good. In this case, the semi-transparent print layer 36a2 can be eliminated, so that the cost can be reduced.

Further, in the second embodiment, two layers of the transparent sheet 36c1 and the transmission prevention printing layer 36c2 are provided, but instead of this, one transparent sheet containing the transmission prevention material may be provided. In this case, the transmission prevention print layer 36c2 can be eliminated, so that the cost can be reduced.

It goes without saying that the present invention is not limited to the above-described embodiment and can be variously modified without departing from the gist thereof.

Specifically, although the lamp 61a is provided in the first and second embodiments, any light source other than the lamp can be provided as the light emitting unit.

Further, in the first and second embodiments described above, the semitransparent printing layer 36a2 is provided by printing on the lower surface of the transparent sheet 36a1, but the semitransparent printing sheet separate from the transparent sheet 36a1 is used as the semitransparent printing unit. It may be provided below the transparent sheet 36a1.

Further, in the above-described embodiment and the second embodiment, the IC card reader 61 is covered with the sheet material 36a or the sheet material 36e, but any device having a light emitting portion other than the IC card reader 61 is covered with the sheet material 36a. Can be done.
