The discrimination unit 207 includes a control unit such as a ROM (Read Only Memory) in which a control program is stored, a RAM (Random Access Memory), and a CPU.

  Further, the cable section 112 of the optical sensor unit 101 shown in FIG. 1 is connected to the control board of the control section of the discrimination section 207.

The control unit of the discrimination unit 207 emits light by driving the plurality of light emitting elements 106, the plurality of visible light emitting elements, and the plurality of infrared light emitting elements shown in FIGS. 1 and 2 in a predetermined pattern.

  The operation of the above configuration will be described.

  The operation of the optical sensor unit 101 of the discrimination unit 207 provided in the banknote handling unit 206 of the automatic transaction apparatus 201 shown in FIG. 4 will be described with reference to FIGS.

Since the cable part 112 of the optical sensor unit 101 is connected to the control board of the control part of the discrimination part 207 shown in FIG. 4, when the predetermined signal is output from the control board, the light emitting element 106 emits predetermined light. Emits ultraviolet light in a pattern.
The ultraviolet light UV emitted from the light emitting element 106 is irradiated to the light emitting element 106 and the cable portion 112 facing each other through the wiring pattern 107, the polyimide layer 108, the polyimide layer 108, the base adhesive 109, and the light guide 103.

At this time, since the wiring pattern 107 and the polyimide layer 108 are formed using non-fluorescent materials, they do not fluoresce and do not emit visible light.
Further, since the base adhesive 109 is irradiated with the ultraviolet light UV through the polyimide layer 108, the intensity of the irradiated ultraviolet light UV is weakened. As a result, the intensity of the ultraviolet fluorescence UVa emitted from the base adhesive 109 is also weakened.

  Here, the operation of the optical sensor unit of the comparative example will be described with reference to FIG.

  The optical sensor unit 501 shown in FIG. 7 includes a visible light cut filter. Here, the visible light cut filter attenuates a weak background visible light component emitted simultaneously with ultraviolet light from the light source, and improves the contrast of the fluorescent image.

  The optical sensor unit 501 corresponds to the optical sensor unit 101 shown in FIGS. 1 and 2, and the configuration other than the cable portion 512 is the same as that of the optical sensor unit 101 shown in FIGS. FIG. 7 is an enlarged view of the region A in FIG. 2 where the cable portion and the light emitting element are arranged, rotated 90 degrees counterclockwise.

  In FIG. 7, the cable portion 512 includes a wiring pattern 507, an insulating layer 509, and a base plate 510.

The insulating layer 509 is made of an epoxy material, and a wiring pattern 507 is formed on one surface, and the base plate 510 is bonded to the other surface.
The wiring pattern 507 is formed on the insulating layer 509 by a known etching method by forming a metal layer by known plating, vapor deposition, or sputtering.

  Further, the visible light cut filter 520 is fixed by a fixing member, and the ultraviolet light UV50 emitted from the light emitting element 506 and the ultraviolet fluorescence L51 emitted by the ultraviolet light UV50 are disposed at a position where the light guide 103 shown in FIG. Then, the ultraviolet fluorescence L51 incident on the light guide 103 is shielded.

Here, the ultraviolet fluorescence is fluorescence (visible light) that is excited and emits light when ultraviolet light hits the epoxy material (insulating layer 509). In the comparative example, it is necessary to provide a visible light cut filter 520 in order to cut this ultraviolet fluorescence (visible light).
A light emitting element 506 is disposed on the cable portion 512, and the anode terminal 506 a and the cathode terminal 506 b of the light emitting element 506 are wire-bonded using bonding wires 511.

  Since the cable unit 512 of the optical sensor unit 501 of the comparative example configured as described above is connected to the control board of the control unit of the discrimination unit 207 illustrated in FIG. 4, a predetermined signal is output from the control board. Thus, the light emitting element 506 emits the ultraviolet light UV50 with a predetermined light emission pattern.

  At this time, the ultraviolet light UV50 emitted from the light emitting element 506 becomes the ultraviolet light UV52 through the visible light cut filter 520. Since the ultraviolet light UV52 passes through the visible light cut filter 520, the intensity is weaker than that of the ultraviolet light UV50.

Further, the ultraviolet light UV 50 is emitted to the base plate 510 through the wiring pattern 507, the insulating layer 509, and the insulating layer 509, and the ultraviolet fluorescent light L 51 is irradiated to the light emitting element 506 and the cable portion 512 facing each other through the light guide body 103.
As described above, in the comparative example including the visible light cut filter, the ultraviolet light emitted from the light emitting element is incident on the light guide through the visible light cut filter, so that the intensity becomes weak.

  However, as in this embodiment shown in FIG. 3, the polyimide layer 108 is prevented from being irradiated with the ultraviolet light UV to the base adhesive 109 as a structure that fluoresces by the ultraviolet light UV emitted from the light emitting element 106. Thus, by arranging, it is not necessary to provide a visible light cut filter, and ultraviolet fluorescence (visible light) can be weakened without using a visible light cut filter.

That is, in this embodiment, since the polyimide layer 108 is used, ultraviolet fluorescence (visible light) hardly emits light, and it is not necessary to use a visible light cut filter, and the ultraviolet fluorescence (visible light) can be weakened.
Therefore, in this embodiment, the ultraviolet light emitted from the light emitting element is irradiated to the light guide without passing through the visible light cut filter, and the intensity of the ultraviolet light emitted from the light guide to the medium passes through the light guide. This is only a loss at the time, and a decrease in the intensity of ultraviolet light can be suppressed.

As described above, in this embodiment, since the fluorescent (visible light) component irradiated to the light guide body is reduced without weakening the intensity of the ultraviolet light emitted from the light emitting element, the contrast of the fluorescent image can be improved. it can.
Furthermore, since the fluorescence (visible light) component can be reduced regardless of the filter performance of the visible light cut filter, a wider range of ultraviolet light can be handled.

  As described above, in the first embodiment, the fluorescent (visible light) component irradiated to the light guide can be reduced without weakening the intensity of the ultraviolet light emitted from the light emitting element, and the fluorescent image can be reduced. It is possible to obtain an effect of suppressing a decrease in contrast.

  The configuration of the second embodiment is different from the first embodiment in the configuration of the cable portion of the optical sensor unit. The configuration of the second embodiment will be described based on the explanatory view showing the configuration of the cable portion in the second embodiment of FIG. FIG. 5 is an enlarged view of the region A in FIG. 2 where the cable portion and the light emitting element are arranged, rotated 90 degrees counterclockwise. The configuration other than the cable portion is the same as the configuration of the first embodiment, and the same parts as those of the first embodiment described above are denoted by the same reference numerals and the description thereof is omitted.

  In FIG. 5, the cable part 312 has the wiring pattern 107, the polyimide layer 108, and the back surface pattern 108b.

The polyimide layer 108 has a wiring pattern 107 formed on one surface and a back surface pattern 108b formed on the other surface.
Furthermore, the back surface pattern 108 b has the base plate 110 bonded to the opposite surface of the polyimide layer 108 via the base adhesive 109.

The back surface pattern 108b is formed of a material that does not fluoresce ultraviolet, such as gold, silver, copper, copper foil, and aluminum. Further, the back surface pattern 108 b can be formed of the same material as that of the wiring pattern 107.
Thus, the back surface pattern 108 b as an ultraviolet light blocking pattern is formed between the polyimide layer 108 and the base adhesive 109.

  The light emitting element 106 is wire-bonded on the polyimide layer 108 of the cable portion 312 using a bonding wire 111.

  The operation of the above configuration will be described.

  The operation of the optical sensor unit 101 of the discrimination unit 207 provided in the banknote handling unit 206 of the automatic transaction apparatus 201 shown in FIG. 4 will be described based on FIGS. 1, 2, and 5.

Since the cable unit 312 of the optical sensor unit 101 is connected to the control board of the control unit of the discrimination unit 207 shown in FIG. 4, the light emitting element 106 emits predetermined light when a predetermined signal is output from the control board. Emits ultraviolet light in a pattern.
The ultraviolet light UV emitted from the light emitting element 106 is irradiated to the light emitting element 106 and the cable portion 312 facing each other through the wiring pattern 107, the polyimide layer 108, the polyimide layer 108, the back surface pattern 108 b, and the light guide 103.

  At this time, since the wiring pattern 107, the polyimide layer 108, and the back surface pattern 108b are formed using non-fluorescent materials, they do not fluoresce.

  As described above, in this embodiment, the back surface pattern 108b is formed between the base adhesive 109 and the polyimide layer 108, so that the ultraviolet light UV emitted from the light emitting element 106 is blocked by the back surface pattern 108b. The base adhesive 109 is not reached. Moreover, since the back surface pattern 108b uses the material which does not fluoresce, it does not fluoresce by ultraviolet light UV.

Therefore, the visible light component irradiated to the light guide 103 is only the visible light component emitted from the light emitting element 106, and the contrast of the fluorescent image can be improved.
As described above, in the second embodiment, in addition to the effects of the first embodiment, the visible light component irradiated to the light guide can be only the visible light component emitted from the light emitting element, Furthermore, the effect that the fall of the contrast of a fluorescence image can be suppressed is acquired.

  The configuration of the third embodiment is different from the first embodiment in the configuration of the cable portion of the optical sensor unit. The configuration of the third embodiment will be described based on the explanatory view showing the configuration of the cable portion in the third embodiment of FIG. FIG. 6 is an enlarged view of the region A in FIG. 2 where the cable portion and the light emitting element are arranged, rotated 90 degrees counterclockwise. The configuration other than the cable portion is the same as the configuration of the first embodiment, and the same parts as those of the first embodiment described above are denoted by the same reference numerals and the description thereof is omitted.

  In FIG. 6, the cable portion 412 includes a wiring pattern 107, a polyimide layer 108, a back surface pattern 108 b, a front panel 408, and an insulating film 410.

The polyimide layer 108 has a wiring pattern 107 formed on one surface and a back surface pattern 108b formed on the other surface.
Furthermore, the back surface pattern 108 b has the base plate 110 bonded to the opposite surface of the polyimide layer 108 via the base adhesive 109.

  The back surface pattern 108b is formed of a material that does not fluoresce ultraviolet, such as gold, silver, copper, copper foil, and aluminum. Further, the back surface pattern 108 b can be formed of the same material as that of the wiring pattern 107.

  Note that the cable portion 412 may be configured without the back surface pattern 108b.

  Further, an insulating film 410 is bonded and fixed to the wiring pattern 107 formed on the polyimide layer 108, that is, on the surface opposite to the surface of the wiring pattern 107 on the polyimide layer 108 side through an insulating film adhesive 411. ing.

  Further, the front panel 408 is bonded and fixed to the one surface of the insulating film 410 to which the wiring pattern 107 is not bonded, that is, the surface opposite to the surface of the insulating film 410 on the wiring pattern 107 side via the front panel adhesive 409. ing.

Since the insulating film adhesive 411 is thermosetting and adheres the insulating film 410 by thermocompression bonding, the insulating film adhesive 411 slightly protrudes to the light emitting element 106 side that is outside the insulating film 410.
The front panel adhesive 409 is placed on the inner side (opposite side of the light emitting element 106) of the edge of the insulating film 410 on the light emitting element 106 side (four side edges, the same applies hereinafter), and the front panel 408 is bonded to the insulating film 410. It protrudes to the light emitting element 106 side from the edge of the agent 411 on the light emitting element 106 side.

  As described above, the edge 408 a on the light emitting element 106 side of the front panel 408 is closer to the light emitting element 106 than the edge 411 a on the light emitting element 106 side of the insulating film adhesive 411 that fixes the insulating film 410 and the wiring pattern 107. doing.

  Further, the edge portion 408 a on the light emitting element 106 side of the front panel 408 is closer to the light emitting element 106 than the edge portion 410 a on the light emitting element 106 side of the insulating film 410.

  Further, the insulating film 410 and the front panel 408 are fixed with a front panel adhesive 409, and the edge 410a on the light emitting element 106 side of the insulating film 410 and the edge 408a on the light emitting element 106 side of the front panel 408 are formed on the front panel. The edge 409a of the adhesive 409 on the light emitting element 106 side is closer to the light emitting element 106.

  Further, the light emitting element 106 is wire-bonded on the polyimide layer 108 of the cable portion 412 using a bonding wire 111.

  The operation of the above configuration will be described.

  The operation of the optical sensor unit 101 of the discrimination unit 207 provided in the banknote handling unit 206 of the automatic transaction apparatus 201 shown in FIG. 4 will be described based on FIGS. 1, 2, and 6.

  Since the cable unit 312 of the optical sensor unit 101 is connected to the control board of the control unit of the discrimination unit 207 shown in FIG. 4, the light emitting element 106 emits predetermined light when a predetermined signal is output from the control board. Emits ultraviolet light in a pattern.

  The ultraviolet light UV emitted from the light emitting element 106 is connected to the wiring pattern 107, the polyimide layer 108, the insulating film 410, the insulating film adhesive 411, the front panel 408, the front panel adhesive 409, and the back surface pattern 108 b through the polyimide layer 108. The light emitting element 106 and the cable portion 412 facing each other through the light body 103 are irradiated.

  At this time, since the wiring pattern 107, the polyimide layer 108, the back surface pattern 108b, the front panel 408, and the insulating film 410 are formed using non-fluorescent materials, they do not fluoresce.

  Further, even if the front panel adhesive 409 and the insulating film adhesive 411 are irradiated with ultraviolet light UV, the front panel 408 having an outer periphery larger than the outer periphery of the front panel adhesive 409 and the insulating film adhesive 411 is formed by the front panel 408. The fluorescent UVd is shielded from light.

  Thus, in this example, the insulating film 410 and the front panel 408 were bonded onto the wiring pattern 107 via the insulating film adhesive 411 and the front panel adhesive 409, respectively. Further, the front panel adhesive 409 is made smaller than the outer periphery of the insulating film 410, and the front panel 408 is made larger than the outer periphery of the insulating film adhesive 411.

Thereby, the ultraviolet fluorescence UVd emitted from the front panel adhesive 409 and the insulating film adhesive 411 is shielded by the front panel 408.
Further, the wiring pattern 107 can be protected by adhering the insulating film 410 onto the wiring pattern 107.

  Therefore, in this embodiment, the wiring pattern 107 is protected, and the front panel 409 and the insulating film adhesive 411 are formed so as to be larger than the outer peripheries of the front panel adhesive 409 and the insulating film adhesive 411. Since the ultraviolet fluorescence UVd is shielded, the contrast of the fluorescence image can be improved.

  Further, the height of the periphery of the light emitting element 106 is increased by the front panel 408 and the insulating film 410. For example, when the resin sealing of the light emitting element 106 is performed, the shape of the resin can be maintained.

  In the present embodiment, as in the second embodiment, the back surface pattern 108b is formed between the base adhesive 109 and the polyimide layer 108. It is shielded by the back pattern 108 b and does not reach the base adhesive 109. Moreover, since the back surface pattern 108b uses the material which does not fluoresce, it does not fluoresce by ultraviolet light UV.

  Therefore, the visible light component irradiated to the light guide 103 is only the visible light component emitted from the light emitting element 106, and the contrast of the fluorescent image can be improved.

  As described above, in the third embodiment, in addition to the effects of the second embodiment, UV fluorescence emitted from the front panel adhesive and the insulating film adhesive is blocked by the front panel while protecting the wiring pattern. Thus, the effect of suppressing the decrease in the contrast of the fluorescent image can be obtained.

  The optical sensor units of the first to third embodiments can obtain a more remarkable effect when sealed with resin. Since the ultraviolet light is reflected at the resin interface, more reflected light is emitted to the outside in the light source. This reflected light includes weak visible light in addition to the ultraviolet light. However, if the optical sensor units of the first to third embodiments are used, it is possible to shield the weak visible light included in the reflected light, and the contrast of the fluorescent image can be improved.

  In the first to third embodiments, the automatic transaction apparatus has been described as an automatic teller machine. However, the present invention is not limited to this, and a ticket or the like is issued if it has an optical sensor unit. It may be an automatic ticket vending machine.
