  Exemplary embodiments of a reader / writer device according to the present invention will be described below in detail with reference to the accompanying drawings. In the following embodiments, an electronic money settlement machine will be described as an example of a reader / writer device.

  1 and 2 are simplified views of an electronic money settlement machine (reader / writer device) according to an embodiment of the present invention. FIG. 1 is a plan view, and FIG. 2 is an XX in FIG. It is line sectional drawing. The electronic money settlement machine exemplified here is a non-contact type with respect to an IC card or a mobile phone which is a recording medium equipped with an IC chip (hereinafter, these recording media will be simply referred to as “money card”). The electronic money information is read and written by communication. Such an electronic money settlement machine includes a device main body 1.

  The apparatus main body 1 has a box-like shape in which various devices are housed, and is provided in such a manner that the tanned portion 2 is exposed. In other words, the tanned portion 2 is disposed in the apparatus main body 1 in a manner to be exposed.

  The tanning part 2 is a part that transmits / receives data to / from a money card that is deceived by a user and held in a predetermined communicable area, and as shown in FIG. 2, the substrate 10, the light emitting plate 20, and the support A member 30 is provided.

  The substrate 10 is disposed inside the apparatus main body 1, and the light emitting element 11 is mounted in a substantially central region of the surface (upper surface). As the light emitting element 11 in the present embodiment, a three-color LED is applied. The three-color LED is a well-known one, and can emit various colors by emitting red, green, and blue light upward. In the present embodiment, a three-color LED is applied as the light emitting element 11, but the present invention is not limited to this, and the type of the light emitting element that can be used as a light source is particularly limited. There is no need to limit.

  In addition to the light emitting element 11, an antenna pattern 12 is attached to the surface of the substrate 10. The antenna pattern 12 is appropriately selected from a conductive metal wire, a metal plate, a metal foil, a metal cylinder, etc., and is formed around the light emitting element 11, and is deceived by the user. Thus, data is acquired from a money card held in a predetermined communicable area due to load fluctuation.

  A filter member 13 is disposed on the substrate 10. More specifically, the filter member 13 is configured such that the engaging piece 131 is inserted into the through hole 101 formed around the mounting portion of the light emitting element 11 of the substrate 10 and is engaged with the substrate 10, thereby 132 is arranged in such a manner as to cover the upper region of the light emitting element 11. The filter member 13 is formed of a resin material such as acrylic resin, and has a milky white color. Here, the milky white degree of the filter member 13 is adjusted in advance to be sufficient to diffuse the light emitted from the light emitting element 11.

  The light emitting plate 20 is made of a resin material such as acrylic resin, and has a transparent circular shape. The light emitting plate 20 is disposed above the substrate 10 in the apparatus main body 1, and a first prism member (first reflecting member) 21 is disposed at a central portion of the back surface (lower surface). . The first prism member 21 has a conical shape, and is arranged in a manner of projecting downward immediately above the light emitting element 11. The first prism body reflects light from the light emitting element 11 to the outer peripheral area of the place where the first prism body is disposed. That is, the conical surface 211 of the first prism member 21 serves as a reflection surface, and reflects light emitted upward from the light emitting element 11 mainly in the planar direction.

  The light emitting plate 20 has an outer peripheral portion protruding upward, and a light emitting region 22 is formed. The surface of the light emitting region 22 becomes the light emitting surface 221. And the back surface 222 of this light emission area | region 22 is processed into the uneven | corrugated shape as shown in FIG. In the present embodiment, the back surface 222 of the light emitting region 22 is processed into an uneven shape. However, the present invention is not limited to this, and the surface of the light emitting region 22 (the light emitting surface 221) has an uneven shape. Alternatively, the front surface (light emitting surface 221) and the back surface 222 of the light emitting region 22 may be processed into an uneven shape.

  In addition, a first reflective sheet 23 is attached to a central region on the surface (upper surface) of the light emitting plate 20, that is, a region surrounded by the light emitting surface 221. The first reflection sheet 23 has a reflection surface formed downward, and reflects light from below toward the lower side. Note that reference numeral 24 in FIGS. 2 and 3 denotes a potting sheet.

  The support member 30 is integrated with the light emitting plate 20 in such a manner as to define a space for arranging the first prism member 21 between the light emitting plate 20 and a passing area of reflected light from the first prism member 21. It is formed. A hole 31 is formed in a central portion of the support member 30, that is, a portion directly below the first prism member 21. The hole portion 31 allows light from the light emitting element 11 to pass through, and is formed in a size that allows the light diffusion portion 132 of the filter member 13 to enter.

  A second prism member (second reflecting member) 32 is disposed on the surface (upper surface) of the support member 30 so as to protrude upward. The second prism member 32 is arranged in an annular shape so as to surround the first prism member 21 in the outer peripheral area of the first prism member 21. More specifically, the second prism member 32 is disposed below the light emitting region 22 of the light emitting plate 20. The second prism member 32 reflects the reflected light from the first prism member 21 through the light emitting region 22 of the light emitting plate 20 with the inner peripheral surface 321 as a reflecting surface. The reflected light is reflected in such a manner that it is transmitted in an annular shape from the rear surface side to the front surface side of the light emitting plate 20. That is, the light reflected by the first prism member 21 in the plane direction is mainly reflected upward.

  In addition, a second reflection sheet 33 is attached to a region excluding the hole 31 on the back surface 222 (lower surface) of the support member 30. The second reflection sheet 33 has a reflection surface formed upward, and reflects light from above toward the upper side.

  In the electronic money settlement machine having such a configuration, the light emitted from the light emitting element 11 is diffused when passing through the light diffusing unit 132 of the filter member 13 and then reaches the first prism member 21. The light that reaches the first prism member 21 is reflected on the outer peripheral area of the first prism member 21.

  Thus, the light (reflected light) reflected by the first prism member 21 on the outer periphery thereof is reflected in the outer periphery of the first prism member 21 so as to surround the first prism member 21. The member 32 is reached. The light that reaches the second prism member 32 is reflected upward and passes through the light emitting region 22 of the light emitting plate 20. Thereby, the light from the light emitting element 11 passes through the light emitting region 22 and is emitted in an annular shape from the light emitting surface 221.

  According to the electronic money settlement machine in the embodiment of the present invention as described above, the first prism member 21 reflects the light from the light emitting element 11 to the outer peripheral area of the place where the first prism member 21 is disposed, The second prism member 32 disposed in an annular shape so as to surround the first prism member 21 in the outer peripheral area of the first prism member 21 transmits the reflected light from the first prism member 21 from the rear surface side of the light emitting plate 20. Since light is reflected in such a manner that it is transmitted in an annular shape toward the surface side, light from the light emitting element 11 can be emitted from the light emitting surface 221 in an annular shape without being blocked. Therefore, the light from the light emitting element 11 is efficiently tanned compared to the conventional case where light from the light emitting element is surface-emitted and a part of the surface light emitting portion is blocked and light is emitted from the glazed portion. Can be released from Thus, since the light from the light emitting element 11 can be efficiently emitted, the minimum necessary amount of light source is sufficient, and it is not necessary to make the amount of light source excessive, which increases the size and cost of the apparatus. There is no fear of inviting. Therefore, the light from the light emitting element 11 can be efficiently emitted from the tanned portion 2, and the cost of the device can be reduced by suppressing the increase in size of the device.

  According to the electronic money settlement machine, the first reflection sheet 23 attached to the surface of the light emitting plate 20 reflects light from the lower side downward and the second reflection attached to the back surface 222 of the support member 30. Since the sheet 33 reflects the light from the upper side upward, the light leaked from the desired reflection direction of the first prism member 21 and the second prism member 32 can also be used effectively. It becomes possible to improve the amount of emitted light.

  Further, according to the electronic money settlement machine, since the back surface 222 of the light emitting area 22 is processed into a concavo-convex shape, the reflected light from the second prism member 32 that passes through the light emitting area 22 can be irregularly reflected, and the light emitting surface 221. Can be emitted uniformly in multiple directions.

  Further, according to the electronic money settlement machine, the filter member 13 diffuses the light from the light emitting element 11, so even if the arrangement distance between the light emitting element 11 and the first prism member 21 is short, the color of the light Variations can be suppressed and light of a desired color can be emitted from the light emitting surface 221. More specifically, for example, when white light is emitted from the light emitting surface 221, it is necessary to emit light of three colors (red, green, and blue) from the light emitting element 11 with a predetermined distribution. When the distance between the first prism member 21 and the first prism member 21 is short, the light from the light emitting element 11 does not diffuse well, and as a result, the color of the light emitted from the light emitting surface 221 varies. However, in this embodiment, since the filter member 13 diffuses the light from the light emitting element 11, even if the arrangement distance between the light emitting element 11 and the first prism member 21 is short, light of a desired color is emitted from the light emitting surface 221. Can be released. And since the arrangement distance of the light emitting element 11 and the 1st prism member 21 can be shortened in this way, it is possible to achieve size reduction (thinning of the whole apparatus) by reducing the size of the tanned portion 2. is there.

  Furthermore, according to the electronic money settlement machine, since the board 10 on which the light emitting element 11 is mounted is provided with the antenna pattern 12 for acquiring data from the money card due to load fluctuation, the board 10 dedicated to the antenna becomes unnecessary. The number of parts can be reduced, and the overall size of the apparatus can be reduced.

  As described above, the reader / writer device according to the present invention is useful for reading and writing data with a recording medium such as an IC card or a mobile phone held in a predetermined communicable area.

It is a top view which shows the electronic money payment machine (reader / writer apparatus) which is embodiment of this invention. It is the XX sectional view taken on the line in FIG. It is the expanded sectional view which expanded and showed the A section in FIG.
