At least an embodiment of the present invention relates to a card insertion unit and a card reader including the card insertion unit.
A card reader in Japanese Laid-open Patent Publication No. 2015-232822 includes a card insertion unit provided with a card insertion slot and a card reader main body that executes processing such as reading or writing of information from or to a card inserted through the card insertion slot. The card insertion unit includes a cover member that is made of translucent resin and is provided with the card insertion slot, a plurality of light sources provided on the back side of the cover member, and a light guide member that is provided between the cover member and the light sources and is configured to illuminate the periphery of the card insertion slot. As the light guide member makes uniform the light emitted by each of the light sources, the periphery of the card insertion slot is uniformly illuminated.
In the market of card readers, there is a need to improve the decorativeness of a card insertion unit with light sources provided to emit lights in different colors at the periphery of a card insertion slot. However, in a card insertion unit including a light guide member, the mixture of lights in different colors results in an undesirable appearance of the overall card insertion unit. Also, the light leaking into the card insertion slot and the mixture of lights in different colors at the card insertion slot result in an undesirable appearance of the card insertion slot. Therefore, there are disadvantages such that it is difficult to place the light sources that emit lights in different colors at the periphery of the card insertion slot and it is difficult to improve the decorativeness.
The object of at least an embodiment of the present invention is to provide a card insertion unit that prevents the mixture of lights in different colors even with the light sources provided to emit lights in different colors at the periphery of a card insertion slot and to provide a card reader including the card insertion unit.
In order to solve the above-described disadvantage, according to at least an embodiment of the present invention, a card insertion unit, provided with a card insertion slot through which a card is inserted, includes: a plurality of light sources that are provided to surround the card insertion slot, when viewed in an insertion direction of the card, with a light emitting unit facing in a direction opposite to the insertion direction so as to each emit lights in multiple colors; a translucent cover member that is provided with the card insertion slot and is overlapped with the light sources in the direction opposite to the insertion direction; and a reflective member that is provided between the light sources and the card insertion slot to reflect light that is to travel from the light sources toward the card insertion slot.
According to at least an embodiment of the present invention, the light sources, which may emit lights in multiple colors, are provided inside the translucent cover member. Specifically, according to at least an embodiment of the present invention, as no light guide member is used, it is possible to prevent the mixture of lights in different colors around the card insertion slot even with the use of the light sources that emit lights in multiple colors. Further, according to at least an embodiment of the present invention, as the reflective member is provided between the light sources and the card insertion slot to reflect the light that is to travel from the light sources toward the card insertion slot, the light is prevented from leaking inside the card insertion slot, and the reflected light is guided to the front side of the cover member. Therefore, it is possible to prevent the mixture of lights in different colors inside the card insertion slot and to brightly illuminate the periphery of the card insertion slot. As a result, according to at least an embodiment of the present invention, as the light sources emitting lights in different colors may be provided at the periphery of the card insertion slot, the decorativeness of the card insertion unit may be improved.
According to at least an embodiment of the present invention, the cover member is preferably provided with a groove portion into which an end of the reflective member on an opposite side of the insertion direction is inserted in the direction opposite to the insertion direction. With this configuration, as the end of the reflective member on the opposite side of the insertion direction is inserted into the groove portion of the cover member, the reflective member may be easily provided between the light sources and the card insertion slot.
According to at least an embodiment of the present invention, a substrate having the light sources mounted on a surface thereof on an opposite side of the insertion direction is preferably included, and the cover member is preferably overlapped with the surface of the substrate on the opposite side of the insertion direction. With this configuration, the size of the card insertion unit may be reduced in the card insertion direction.
According to at least an embodiment of the present invention, the surface of the substrate on the opposite side of the insertion direction is preferably provided with a reflective layer. With this configuration, as the light reflected by the reflective layer is guided to the cover member, the periphery of the card insertion slot may be brightly illuminated.
According to at least an embodiment of the present invention, each of the light sources may include a light emitting diode to emit red light, a light emitting diode to emit green light, and a light emitting diode to emit blue light. In this case, according to at least an embodiment of the present invention, a light emitting diode control unit to control the light sources so as to change colors emitted from the light sources is preferably included. With this configuration, the light sources may emit lights in multiple colors, and the light sources may emit light in a variety of emission patterns.
According to at least an embodiment of the present invention, the card insertion unit and a card reader main body to which the card insertion unit is secured are included. With the card reader, there is no mixture of lights in different colors even when the periphery of the card insertion slot is illuminated in different colors, whereby the decorativeness of the card insertion unit may be improved.
According to at least an embodiment of the present invention, as it is possible to prevent the mixture of lights in different colors even with the light sources provided to emit lights in different colors at the periphery of a card insertion slot, the decorativeness of the card insertion unit may be improved.

The opening 7a, the opening 8a, and the opening 12a have the same size and shape and are overlapped with the card insertion slot 2 in the X-direction. The opening 7a, the opening 8a, and the opening 12a constitute a conveyance passage through which the card 100 passes.
A white reflective layer 13 is provided on a surface 71 of the rigid substrate 7 on the side of the X2-direction. The reflective layer 13 reflects, toward the X2-direction, the light emitted from the light sources 10 toward the X1-direction. The reflective layer 13 may be any reflective surface that reflects light, and the color of the reflective layer 13 may be a color other than white. For example, the color of the reflective layer 13 may be silver.
The light sources 10 are mounted on the surface 71 of the rigid substrate 7 with light emitting units facing the X2-direction. More specifically, as illustrated in
The light source 10 is a light emitting diode (LED) array in which an LED that emits red light, an LED that emits green light, and an LED that emits blue light are arrayed. The rigid substrate 7 on which the light sources 10 are mounted is electrically connected to the control board 5 via a cable, or the like. A LED control unit mounted on the control board 5 controls the emission intensities of the three LEDs in red, green, and blue so that the light sources 10 emit lights in multiple colors.
The cover member 6 is made of a resin material. The cover member 6 also has translucency. In the present mode, the cover member 6 is made of a translucent material in opaque white. The cover member 6 may be made of an opaque translucent material in a color other than opaque white, such as gray.

As illustrated in
The reflective member 11 is made of metal or resin to reflect the light that is to travel from the light sources 10 toward the card insertion slot 2 and the conveyance passage. Specifically, as the light that is to travel from the light sources 10 toward the card insertion slot 2 and the conveyance passage is blocked by the reflective member 11, the light that is to travel from the light sources 10 toward the card insertion slot 2 and the conveyance passage does not pass through the card insertion slot 2 and the conveyance passage. In the present mode, the reflective member 11 is white. The reflective member 11 may be any member that reflects light, and the color of the reflective member 11 may be a color other than white. For example, the color of the reflective member 11 may be silver.
The card reader 1 according to the present mode is installed in a game machine provided in casinos, game arcades, or the like, and the card reader 1 is used while the card 100 is inserted into the card reader 1. When the card 100 is inserted into the card reader 1, the light source 10 emits light toward the cover member 6 so that the peripheral portion of the card insertion slot 2 of the card insertion unit 3 is illuminated. When the peripheral portion of the card insertion slot 2 of the card insertion unit 3 is illuminated, the inside of the card insertion slot 2 and the conveyance passage is dark as the light that is to travel from the light sources 10 toward the card insertion slot 2 and the conveyance passage is reflected by the reflective member 11.
Control on Light Sources
Next, the control on the light sources 10 is described.
In the present mode, the LED control circuit 22 may perform control such that the light sources 10 emit lights in six colors, i.e., green, light blue, blue, purple, red, and yellow. Therefore, for example, the LED control circuit 22 may perform control such that, among the six light sources 10, the two light sources 10 emit red light, the two light sources 10 emit green light, and the two light sources 10 emit blue light. Also, the LED control circuit 22 may perform control such that, among the six light sources 10, the three light sources 10 emit red light and the three light sources 10 emit green light.
The LED control circuit 22 may control all the six light sources 10 to emit lights in different colors and sequentially switch the emission in green, light blue, blue, purple, red, and then yellow so as to change the color of each of the light sources 10. That is, the LED control circuit 22 may control the emission of each of the light sources 10 so as to allow the light sources 10 to emit light in a variety of emission patterns. Accordingly, the card reader 1 according to the present mode may cause the peripheral portion of the card insertion slot 2 of the card insertion unit 3 to be illuminated in a variety of emission patterns so as to improve the decorativeness of the card insertion unit 3.
Advantage of the Present Mode
The present mode includes the light sources 10 that are provided to surround the card insertion slot 2, when viewed in the X1-direction, with the light emitting units facing the X2-direction so as to each emit lights in multiple colors, the translucent cover member 6 that is provided with the card insertion slot 2 and overlapped with the light sources 10 in the X2-direction, and the reflective member 11 that is provided between the light sources 10 and the card insertion slot 2 to reflect the light that is to travel from the light sources 10 toward the card insertion slot 2. As no light guide member is used, it is possible to prevent the mixture of lights in different colors around the card insertion slot 2 even with the use of the light sources that emit lights in multiple colors. According to at least an embodiment of the present invention, as the reflective member 11 is provided between the light sources 10 and the card insertion slot 2 to reflect the light that is to travel from the light sources 10 toward the card insertion slot 2, the light is prevented from leaking inside the card insertion slot 2, and the reflected light is guided to the front side of the cover member 6. Therefore, it is also possible to prevent the mixture of lights in different colors inside the card insertion slot 2 and to brightly illuminate the periphery of the card insertion slot 2. As a result, in the present mode, as the light sources 10 emitting lights in different colors may be provided at the periphery of the card insertion slot 2, the decorativeness of the card insertion unit 3 may be improved.
According to the present mode, the cover member 6 is provided with the groove portion 67 into which the end 11a of the reflective member 11 on the side of the X2-direction is inserted in the X2-direction. As the end 11a of the reflective member 11 on the side of the X2-direction is inserted into the groove portion 67 of the cover member 6, the reflective member 11 may be easily provided between the light sources 10 and the card insertion slot 2.
According to the present mode, the rigid substrate 7 with the light sources 10 mounted on the surface 71 on the side of the X2-direction is provided, and the cover member 6 is overlapped with the surface 71 of the rigid substrate 7. Thus, the size of the card insertion unit 3 may be reduced in the card insertion direction.
According to the present mode, the reflective layer 13 is provided on the surface 71 of the rigid substrate 7. Thus, as the light reflected by the reflective layer 13 is guided to the cover member 6, the periphery of the card insertion slot 2 may be brightly illuminated.
According to the present mode, each of the light sources 10 includes the LED 10R that emits red light, the LED 10G that emits green light, and the LED 10B that emits blue light. The present mode includes the LED control circuit 22 that controls the light sources 10 so as to change the colors emitted from the light sources 10. Thus, the light sources 10 may emit lights in multiple colors, and the light sources 10 may emit lights in a variety of emission patterns.
Modification
In the above-described embodiment, the end 11a of the reflective member 11 on the side of the X2-direction is inserted into the groove portion 67; however, this configuration is not a limitation. For example, a configuration may be such that the reflective member 11 is attached to the inner peripheral wall 68 with an adhesive, or the like. Even with this configuration, the light that is to travel from the light sources 10 toward the card insertion slot 2 is reflected by the reflective member 11. Thus, it is possible to prevent the mixture of lights in different colors at the card insertion slot 2 and to brightly illuminate the periphery of the card insertion slot 2.
