TECHNICAL FIELD
At least an embodiment of the present invention relates to a card insertion part for a card reader formed with a card insertion port into which a card is inserted, and to a card reader provided with the card insertion part.
BACKGROUND
Conventionally, a card gate mechanism (card insertion part) structuring a part of a card reader has been known (see, for example, Patent Literature 1). The card insertion part described in Patent Literature 1 includes a light source part, a light guide member which guides a light emitted from the light source part, and a gate frame formed with a gate port (card insertion port) into which card is to be inserted. The gate frame is formed in a hollow shape and the light source part and the light guide member are disposed inside the gate frame. Further, the gate frame is formed of transparent material which transmits light. Therefore, in the card insertion part, when a light is emitted from the light source part toward the light guide member, the gate frame formed with the card insertion port is illuminated. In other words, when a light is emitted from the light source part toward the light guide member in the card insertion part, a peripheral portion of the card insertion port is illuminated.

In this embodiment, a card 2 is passed in an “X” direction shown in FIG. 1. Specifically, a card 2 is inserted in an “X1” direction and the card 2 is pulled out in an “X2” direction. In other words, the “X1” direction is an inserting direction of a card 2, and the “X2” direction is a pulling-out direction of the card 2. Further, a “Z” direction in FIG. 1 perpendicular to the “X” direction is a thickness direction of a card 2 taken into the card reader 1, and a “Y” direction in FIG. 1 perpendicular to the “X” direction and the “Z” direction is a width direction of a card 2 taken into the card reader 1. In the following descriptions, the “X” direction is referred to as a “front and rear direction”, the “Y” direction is referred to as a “right and left direction”, and the “Z” direction is referred to as an “upper and lower direction”. Further, the “X1” direction side is referred to as a “rear (back)” side, the “X2” direction side is referred to as a “front” side, the “Y1” direction side is as a “right” side, the “Y2” direction side is as a “left” side, the “Z1” direction side is as an “upper” side, and the “Z2” direction side is as a “lower” side. In this embodiment, the “X1” direction side is a rear side in an inserting direction of a card 2, and the “X2” direction side is a front side in the inserting direction of a card 2.
A card 2 is, for example, a substantially rectangular-shaped card made of vinyl chloride whose thickness is about 0.7-0.8 mm. A rear face of a card 2 is formed with a magnetic stripe in which magnetic data are recorded. Further, an IC chip is incorporated into a card 2, and a front face of the card 2 is formed with an external connection terminal of the IC chip. A card 2 may be formed with only one of a magnetic stripe or an external connection terminal. Further, a card 2 may be a PET (polyethylene terephthalate) card whose thickness is about 0.18-0.36 mm or may be a paper card having a predetermined thickness.
The main body part 5 includes a magnetic head (not shown) configured to perform reading of magnetic data recorded on a card 2 and/or recording of magnetic data to a card 2, an IC contact block configured to contact with an external connection terminal of an IC chip of the card 2 to perform data communication with the card 2, and the like. The card insertion part 4 is attached to a front end face of the main body part 5. Next, a structure of the card insertion part 4 will be described below.

Therefore, in this embodiment, the light sources 7 through 10 are disposed on outer sides in the right and left direction with respect to the projecting part 14b. In other words, in this embodiment, when viewed in the front and rear direction, the light sources 7 through 10 are disposed at positions where they do not overlap with an exposed portion (in other words, the projecting part 14b) of the card insertion part 4 in the front panel of a game machine. A width of the projecting part 14b in the upper and lower direction is set to be wider than a width of the light guide member 13 in the upper and lower direction. Further, a width of the projecting part 14b in the right and left direction is set to be wider than a width of the card insertion port 3 in the right and left direction.
As described above, the card reader 1 in this embodiment is mounted on a game machine which is installed in a casino or a game arcade. The card reader 1 is used in a state that a card 2 is inserted into the card reader 1. Further, in a state that a card 2 is inserted into the card reader 1, the light sources 7 through 10 emit lights toward the light guide member 13 and thus a peripheral portion of the card insertion port 3 of the card insertion part 4 is illuminated.
(Principal Effects in this Embodiment)
As described above, in this embodiment, the light guide member 13 is formed so as to surround the entire periphery of the card insertion port 3 when viewed in the front and rear direction, and the front face 11b of the rigid circuit board 11 is formed as a reflection face configured to reflect light emitted toward a rear side from the light guide member 13 toward a front side. Further, in this embodiment, the cover member 14 covers the light sources 7 through 10, the rigid circuit board 11 and the light guide member 13 from the front side. Therefore, according to this embodiment, lights from the light sources 7 through 10 can be diffused over the entire peripheral portion of the card insertion port 3 on the rear side of the cover member 14 by operation of the light guide member 13 and the front face 11b. Further, in this embodiment, the cover member 14 is formed of translucent light transmissive material and thus light transmitting through the cover member 14 toward the front side can be made dull. As described above, in this embodiment, the light can be diffused over the entire peripheral portion of the card insertion port 3 on the rear side of the cover member 14 and the light diffused over the entire peripheral portion of the card insertion port 3 on the rear side of the cover member 14 can be made dull by the cover member 14. Therefore, according to this embodiment, the entire peripheral portion of the card insertion port 3 is capable of being illuminated uniformly, dully and beautifully.
Especially, in this embodiment, the light source 7 is disposed on an upper end side of the light guide member 13 so as to a emit light from a left end of the light guide member 13 to the right direction, and the light source 8 is disposed on a lower end side of the light guide member 13 so as to emit a light from a left end side of the light guide member 13 to the obliquely right upper direction. Further, the light source 9 is disposed on a lower end side of the light guide member 13 so as to emit a light from the right end of the light guide member 13 to the left direction, and the light source 10 is disposed on an upper end side of the light guide member 13 so as to emit a light from the right end side of the light guide member 13 to the obliquely left lower direction. Therefore, according to this embodiment, the light can be effectively diffused over the entire peripheral portion of the card insertion port 3 on the rear side of the cover member 14. Accordingly, in this embodiment, the entire peripheral portion of the card insertion port 3 can be illuminated further uniformly.
In this embodiment, the cover member 14 is formed of light transmissive material of a milk-white color and thus the entire peripheral portion of the card insertion port 3 can be further beautifully illuminated with various colors. Further, in this embodiment, the light sources 7 through 10 are disposed on outer sides in the right and left direction with respect to the projecting part 14b and, when viewed in the front and rear direction, the light sources 7 through 10 are disposed at positions where they do not overlap with an exposing portion of the card insertion part 4 in the front panel of a game machine. Therefore, according to this embodiment, the entire peripheral portion of the card insertion port 3 which is exposed in the front panel of a game machine on which the card reader 1 is mounted can be illuminated further uniformly, further dully and beautifully.
In this embodiment, the front face 11b of the rigid circuit board 11 is formed to be a reflection face configured to reflect light irradiated toward the rear side from the light guide member 13 toward the front side. Therefore, according to this embodiment, another reflection member for reflecting light irradiated toward a rear side from the light guide member 13 toward a front side is not required to provide separately in addition to the rigid circuit board 11 on which the light sources 7 through 10 are mounted. Accordingly, in this embodiment, a structure of the card insertion part 4 can be simplified.
In this embodiment, the light guide member 13 is formed in a flat plate shape and is disposed so as to contact with the front face 11b of the rigid circuit board 11, and the light sources 7 through 10 are disposed so as to emit lights toward the end faces of the light guide member 13. Therefore, according to this embodiment, the size of the card insertion part 4 can be reduced in the front and rear direction.
First Modified Embodiment of Card Insertion Part
FIGS. 3 and 4 are explanatory front views showing a structure of a card insertion part 4 in accordance with another embodiment of the present invention.
In the embodiment described above, the light source 8 is disposed so that a light emission face of the light source 8 faces the chamfer part 13b formed at a corner part of a left lower end of the light guide member 13, and the light source 10 is disposed so that a light emission face of the light source 10 faces the chamfer part 13b formed at a corner part of a right upper end of the light guide member 13. However, the present invention is not limited to this embodiment. For example, as shown in FIG. 3, it may be structured that a light source 8 is disposed so that a light emission face of the light source 8 faces a lower end face of the light guide member 13 on a left end side of the light guide member 13, and that a light source 10 is disposed so that a light emission face of the light source 10 faces an upper end face of the light guide member 13 on a right end side of the light guide member 13. In other words, it may be structured that the light source 8 is disposed so as to emit a light to an upper direction from a lower end of the light guide member 13 to an upper end side of the light guide member 13 on a left end side of the light guide member 13, and that the light source 10 is disposed so as to emit a light to a lower direction from an upper end of the light guide member 13 to a lower end side of the light guide member 13 on a right end side of the light guide member 13. In the card insertion part 4 shown in FIG. 3, the light sources 8 and 10 are disposed on outer sides in the upper and lower direction with respect to the projecting part 14b. In other words, the light sources 8 and 10 are disposed at positions where they do not overlap with an exposing portion (in other words, the projecting part 14b) of the card insertion part 4 in the front panel of a game machine when viewed in the front and rear direction.
Also in the card insertion part 4 shown in FIG. 3, light can be effectively diffused over the entire peripheral portion of the card insertion port 3 on the rear side of the cover member 14 and, as a result, the entire peripheral portion of the card insertion port 3 can be illuminated further uniformly. Further, in the card insertion part 4 shown in FIG. 3, no chamfer part 13b may be formed in the light guide member 13. In a case that the light sources 8 and 10 are disposed so as to face the chamfer parts 13b of the light guide member 13 like the embodiment described above, in comparison with a case that the light sources 8 and 10 are disposed so as to face upper and lower end faces of the light guide member 13 as shown in FIG. 3, the size of the card insertion part 4 can be reduced in the upper and lower direction.
Further, as shown in FIG. 4, it may be structured that the light source 8 is disposed on a lower end side of the light guide member 13 and is disposed so as to emit a light to the right direction from a left end of the light guide member 13 toward the right end side of the light guide member 13, and that the light source 10 is disposed on an upper end side of the light guide member 13 and is disposed so as to emit a light to the left direction from a right end of the light guide member 13 toward the left end side of the light guide member 13. Also in the card insertion part 4 shown in FIG. 4, the light sources 7 through 10 are disposed at positions where they do not overlap with an exposing portion (in other words, the projecting part 14b) of the card insertion part 4 in the front panel of a game machine when viewed in the front and rear direction.
In the embodiment described above, the card insertion part 4 includes four light sources 7 through 10. However, the number of light sources included in the card insertion part 4 may be five or more. Alternatively, the number of light sources included in the card insertion part 4 may be not more than 3. For example, as shown in FIG. 4, in a case that a difference between a width in the right and left direction of the projecting part 14b which is an exposing portion of the card insertion part 4 in the front panel of a game machine and a width in the right and left direction of the card insertion port 3 is small, the card insertion part 4 may be provided with only the light source 7 and the light source 9, or may be provided with only the light source 8 and the light source 10.
In the embodiment described above and the modified embodiments shown in FIGS. 3 and 4, the front face 11b of the rigid circuit board 11 is formed to be a reflection face. However, the front face 11b may be formed with no reflection face. In this case, it may be structured that a reflection member configured to reflect light is disposed between the rigid circuit board 11 and the light guide member 13 in the front and rear direction. Further, in the embodiment described above and the modified embodiments shown in FIGS. 3 and 4, the light sources 7 through 10 are disposed at positions where they do not overlap with an exposing portion (in other words, the projecting part 14b) of the card insertion part 4 in the front panel of a game machine when viewed in the front and rear direction. However, at least one of the light sources 7 through 10 may be disposed at a position overlapping with the projecting part 14b when viewed in the front and rear direction. In addition, in the embodiment described above and the modified embodiments shown in FIGS. 3 and 4, the light sources 7 through 10 are disposed so as to emit lights toward end faces of the light guide member 13. However, it may be structured that a gap space is formed between the rigid circuit board 11 and the light guide member 13 in the front and rear direction, and that light sources 7 through 10 may be disposed so as to emit lights toward a rear side face of the light guide member 13.
Second Modified Embodiment of Card Insertion Part
FIGS. 5(A) and 5(B) are explanatory views showing a structure of a card insertion part 4 in accordance with another embodiment of the present invention. FIG. 5(A) is its plan view and FIG. 5(B) is its front view. FIG. 6 is an explanatory plan view showing a structure of a card insertion part 4 in accordance with another embodiment of the present invention.
In the embodiments described above, the card insertion part 4 is formed in a substantially rectangular stepped tube shape which is flat in a front and rear direction. However, the present invention is not limited to this embodiment. For example, as shown in FIGS. 5(A) and 5(B), a cut-out part 4a which is cut out from a front end of a card insertion part 4 toward a rear side may be formed at a middle position in the right and left direction of the card insertion part 4. In the card insertion part 4 shown in FIGS. 5(A) and 5(B), a card insertion port 3 is formed on both sides of the cut-out part 4a in the right and left direction. Further, the card insertion part 4 includes light sources 7 through 10, two guide parts 20 and 21 which are formed with a part of the card passage where a card 2 is passed, two light guide members 22 and 23 which are disposed on a front side of the guide parts 20 and 21, and a cover member 24 in which the card insertion port 3 is formed. In FIG. 5(B), the guide parts 20 and 21 are not shown.
The guide parts 20 and 21 are formed in a substantially rectangular block shape which is long and thin in the front and rear direction and are disposed on both sides of the cut-out part 4a in the right and left direction. Specifically, the guide member 20 is disposed on the left side of the cut-out part 4a and the guide member 21 is disposed on the right side of the cut-out part 4a. The guide parts 20 and 21 are formed with recessed parts which are recessed from inner side ends of the guide parts 20 and 21 in the right and left direction toward outer sides in the right and left direction and these recessed parts structure a part of the card passage.
The light guide members 22 and 23 are formed in a flat plate shape and are disposed so that thickness directions of the light guide members 22 and 23 and the front and rear direction are coincided with each other. The light guide member 22 is disposed on a front side of the guide part 20 and the light guide member 23 is disposed on a front side of the guide part 21. Specifically, the light guide member 22 is disposed so as to contact with a front end of the guide part 20, and the light guide member 23 is disposed so as to contact with a front end of the guide part 21. The light guide members 22 and 23 are formed with slits 22a and 23a where a card 2 is passed. The slits 22a and 23a are, as shown in FIG. 5(B), formed so as to be cut out from inner side ends in the right and left direction of the light guide members 22 and 23 toward outer sides in the right and left direction.
Light sources 7 and 8 are disposed on a left end side and a rear side of the light guide member 22 with a predetermined space therebetween in the upper and lower direction. Specifically, the light sources 7 and 8 are disposed so as to emit lights toward the light guide member 22 from a rear side of the light guide member 22. Light sources 9 and 10 are disposed on a right end side and a rear side of the light guide member 23 with a predetermined space therebetween in the upper and lower direction. Specifically, the light sources 9 and 10 are disposed so as to emit lights toward the light guide member 23 from a rear side of the light guide member 23. Further, when viewed in the front and rear direction, the light sources 7 through 10 are disposed on outer sides in the right and left direction with respect to the card insertion port 3.
Chamfer parts 22b and 23b are formed on front faces of both right and left ends of the light guide members 22 and 23. The chamfer part 22b formed at the left end of the light guide member 22 is stuck with a reflection member (not shown) formed in a thin plate shape or a film shape, and the chamfer part 23b formed at the right end of the light guide member 23 is stuck with a reflection member (not shown) formed in a thin plate shape or a film shape. For example, a silver seal is stuck as a reflection member on the chamfer parts 22b and 23b. The reflection members function to reflect lights emitted from the light sources 7 through 10 from a rear side of the light guide members 22 and 23 to diffuse in the entire light guide members 22 and 23.
Further, portions of rear side faces of the light guide members 22 and 23 at least other than emitted parts to which lights from the light sources 7 through 10 are emitted are stuck with a reflection member (not shown) formed in a thin plate shape or a film shape. For example, a white seal is stuck as a reflection member on rear side faces of the light guide members 22 and 23. The reflection members function to reflect lights irradiated toward rear sides from the light guide members 22 and 23 toward front sides. In the card insertion part 4 shown in FIGS. 5(A) and 5(B), no reflection member is stuck on a right end side portion of the rear side face of the light guide member 22 and a left end side portion of the rear side face of the light guide member 23. However, a reflection member may be stuck on a right end side portion of the rear side face of the light guide member 22 and a left end side portion of the rear side face of the light guide member 23.
The cover member 24 is, similarly to the cover member 14, formed of translucent light transmissive material. Specifically, the cover member 24 is formed of light transmissive material of a milk-white color. Further, the cover member 24 is formed so as to cover the guide part 20 and the light guide member 22 from a front side, both upper and lower sides and both right and left sides and, in addition, so as to cover the guide part 21 and the light guide member 23 from a front side, both upper and lower sides and both right and left sides. In other words, the cover member 24 is provided with a front face part 24a which covers the guide part 20 and the light guide member 22 from the front side, and a front face part 24b which covers the guide part 21 and the light guide member 23 from the front side. Further, the cover member 24 is provided with a cover part 24c which covers the guide part 20 and the light guide member 22 from a right side, and a cover part 24d which covers the guide part 21 and the light guide member 23 from a left side. In other words, the cover member 24 is provided with the cover parts 24c and 24d which are disposed on both sides of the cut-out part 4a and cover the guide parts 20 and 21 from inner sides in the right and left direction.
The front face parts 24a and 24b and the cover parts 24c and 24d are formed with a slit where a card 2 is passed. The slits formed in the front face parts 24a and 24b are formed as the card insertion port 3. As described above, the light guide members 22 and 23 are formed with the slits 22a and 23a where a card 2 is passed and, as shown in FIG. 5(B), the light guide members 22 and 23 are formed so as to surround parts of a periphery of the card insertion port 3 when viewed in the front and rear direction. Further, in the right and left direction, a space “S1” is formed between the guide part 20 and the cover part 24c, and a space “S2” is formed between the guide part 21 and the cover part 24d. 
In the card insertion part 4 shown in FIGS. 5(A) and 5(B), the light guide members 22 and 23 are formed so as to surround parts of a periphery of the card insertion port 3 when viewed in the front and rear direction. Further, in the card insertion part 4, a reflection member is stuck on portions of the rear side faces of the light guide members 22 and 23 at least except emitted parts to which lights are emitted from the light sources 7 through 10. Further, in the card insertion part 4, the front face parts 24a and 24b of the cover member 24 cover the light guide members 22 and 23 from a front side. Therefore, in the card insertion part 4, lights from the light sources 7 through 10 can be diffused over the entire peripheral portion of the card insertion port 3 on the rear sides of the front face parts 24a and 24b. Further, the cover member 24 is formed of translucent light transmissive material and thus lights transmitted through the front face parts 24a and 24b toward a front side can be made dull. Therefore, in the card insertion part 4 shown in FIGS. 5(A) and 5(B), even when the cut-out part 4a is formed in the card insertion part 4, the entire peripheral portion of the card insertion port 3 can be illuminated uniformly, dully and beautifully.
Further, in the card insertion part 4 shown in FIGS. 5(A) and 5(B), a space “S1” is formed between the guide part 20 and the cover part 24c, and a space “S2” is formed between the guide part 21 and the cover part 24d. Further, in the card insertion part 4 shown in FIGS. 5(A) and 5(B), no reflection member is stuck on a right end side portion of the rear side face of the light guide member 22 and a left end side portion of the rear side face of the light guide member 23. Therefore, in the card insertion part 4, both sides in the right and left direction of the cut-out part 4a can be illuminated dully by utilizing the spaces “S1” and “S2”. Further, in the card insertion part 4, the light sources 7 through 10 are disposed so as to emit lights toward the light guide members 22 and 23 from rear sides of the light guide members 22 and 23 and thus the size of the card insertion part 4 can be reduced in the right and left direction.
In addition, in the card insertion part 4, the reflection members stuck on the rear side faces of the light guide members 22 and 23 are formed in a thin plate shape or a film shape. Therefore, even when the reflection members configured to reflect lights irradiated toward rear sides from the light guide members 22 and 23 toward a front side are provided, the size of the card insertion part 4 can be reduced in the front and rear direction. In the card insertion part 4 shown in FIGS. 5(A) and 5(B), it may be structured that no space “S1” is formed between the guide part 20 and the cover part 24c and no space “S2” is formed between the guide part 21 and the cover part 24d. 
In the card insertion part 4 shown in FIGS. 5(A) and 5(B), the light guide members 22 and 23 are formed in a flat plate shape. However, as shown in FIG. 6, the light guide members 22 and 23 may be structured of first light guide parts 22f and 23f in a flat plate shape which are disposed on front sides of the guide parts 22 and 23, and second light guide parts 22g and 23g in a flat plate shape which are connected with inner side ends of the first light guide parts 22f and 23f in the right and left direction and are disposed in the spaces “S1” and “S2”. In other words, the light guide members 22 and 23 may be formed in a substantially “L”-shape when viewed in the upper and lower direction. In this case, lights can be diffused in the whole of the spaces “S1” and “S2” by operation of the second light guide parts 22g and 23g and thus the whole of both sides in the right and left direction of the cut-out part 4a can be illuminated dully and beautifully.
Further, in this case, as shown in FIG. 6, it is preferable that the first light guide parts 22f and 23f and the second light guide parts 22g and 23g are connected with each other through smooth gradually curved faces. Alternatively, the first light guide parts 22f and 23f and the second light guide parts 22g and 23g may be separately formed from each other. However, it is preferable that, as shown in FIG. 6, the first light guide parts 22f and 23f and the second light guide parts 22g and 23g are integrally formed with each other without gaps. In other words, it is preferable that the first light guide part 22f and the second light guide part 22g are formed as one component and that the first light guide part 23f and the second light guide part 23g are formed as one component.
In the card insertion part 4 shown in FIGS. 5(A) and 5(B) or FIG. 6, the card insertion part 4 may be provided with only one of the light source 7 and the light source 8. Further, in the card insertion part 4 shown in FIGS. 5(A) and 5(B) or FIG. 6, the card insertion part 4 may be provided with only one of the light source 9 and the light source 10.
