[0008] Hereinafter, an embodiment of a card reader to which the present invention is applied will be described with reference to the drawings.

[0009] (Embodiment 1) Figure 1 is an external perspective view of the card reader of Embodiment 1. Figure 2 is an exploded perspective view of the card reader of Embodiment 1. Figure 3 is a schematic cross-sectional view taken at line AA in Figure 1. Figure 4 is a schematic cross-sectional view taken at line BB in Figure 3. Figure 5 is a perspective view of the cover member. Note that the imaging unit 7 is omitted in Figure 4.

[0010] In this specification, the three directions X, Y, and Z are mutually orthogonal axes. The X direction along the X-axis is the front-to-back direction of the card reader 100. In the X direction, X1 is forward and X2 is backward. The card 10 is inserted into the card reader 100 in the X2 direction and removed from the card reader 100 in the X1 direction. The Y direction along the Y-axis is the width direction of the card reader 100. The Z direction along the Z-axis is the height (thickness) direction of the card reader 100. In the Z direction, Z1 is upward and Z2 is downward.

[0011] The card reader 100 shown in Figure 1 is a device for reading data recorded on a card 10 and recording data onto the card 10. For example, the card reader 100 is mounted on information equipment 200 such as game machines placed in casinos, arcades, etc. The card reader 100 is attached to the mounting surface 202 on the inside of the case 201 of the information equipment 200. In Figure 1, the case 201 is shown as a partial cross-sectional view. The mounting hole 203 is approximately rectangular in shape with the Y direction as the longer side.

[0012] Card 10 is, for example, a roughly rectangular card made of polyvinyl chloride with a thickness of about 0.7 to 0.8 mm. A magnetic stripe (not shown) for recording magnetic data is formed on the back of card 10. An IC chip is also embedded in card 10, and external connection terminals (not shown) for the IC chip are formed on the front of card 10. Note that card 10 may have only one of either the magnetic stripe or the external connection terminals. Card 10 may also be a PET (polyethylene terephthalate) card with a thickness of about 0.18 to 0.36 mm, or a paper card of a predetermined thickness.

[0013] The card reader 100 in this configuration is capable of accessing information on card 10. Specifically, the card reader 100 has the function of accessing information on card 10 by making contact with card 10 and reading and writing that information, as well as accessing information on card 10 by communicating with card 10 contactlessly and reading and writing that information. As shown in Figures 1 and 2, the card reader 100 comprises a card reader body 2 and a cover member 3 fixed to the card reader body 2 in the X1 direction. The cover member 3 is provided with an insertion slot 30 connected to the card passage 22 of the card reader body 2. Card 10 is inserted through the insertion slot 30. The card reader body 2 includes a magnetic head for reading and writing magnetic data recorded on the magnetic stripe of card 10 inserted into the card passage 22, and an IC contact block for communicating data with card 10 by making contact with the external connection terminals of the IC chip of card 10. A base plate 21 (first end) for fixing the cover member 3 is provided in the X1 direction of the card reader body 2. The base plate 21 is located on the outside in the Y direction of the card passage 22.

[0014] The cover member 3 is made of a translucent resin. As shown in Figures 1 and 2, the cover member 3 is fixed to the base plate 21 by screws 15. As shown in FIGS. 2, 3, and 5, the cover member 3 includes a protruding portion 31 that is inserted into a mounting hole portion 203 provided in the case 201 and protrudes from the case 201 in the X1 direction, and a flange portion 32 that is connected to the end portion of the protruding portion 31 in the X2 direction and fixed to the mounting surface 202. The protruding portion 31 has a substantially rectangular shape with the Y direction as the long side direction, and is inserted into the mounting hole portion 203 from the X2 direction. The flange portion 32 is fixed to the mounting surface 202 by a fixing member such as a screw (not shown). Thereby, the card reader 100 is attached inside the case 201 of the information device 200. Note that the case 201 is made of resin or metal.

[0015] As shown in FIGS. 2, 3, and 5, the protruding portion 31 includes a front surface portion 34 in which an insertion port 30 is formed, an outer peripheral wall portion 35 that extends in the X2 direction from the outer peripheral edge of the front surface portion 34 and is connected to the flange portion 32, and an opening cylinder portion 36 that surrounds the edge of the insertion port 30 and protrudes in the X2 direction from the front surface portion 34. A holding portion 38 for holding the imaging portion 7 is provided at the end portion of the front surface portion 34 in the Y2 direction. The front end surface 381 on the X2 side of the holding portion 38 is inclined obliquely downward with respect to the YZ plane that is a vertical plane. An internal space S is formed between the outer peripheral wall portion 35 and the opening cylinder portion 36.

[0016] As shown in FIGS. 2, 3, and 5, the flange portion 32 has a substantially rectangular shape with the Y direction as the long side direction, which extends in the Y direction and the Z direction from the end portion of the protruding portion 31 in the X2 direction. The flange portion 32 includes a flange surface 321 facing the X1 direction. The flange surface 321 contacts the mounting surface 202. An opening 320 is formed in the flange portion 32. The opening 320 communicates with the internal space S.

[0017] As shown in FIGS. 1 and 2, the card reader 100 includes an antenna 4, a spacer member 5, a rigid substrate 6, an imaging portion 7, and a control substrate 8. The control substrate 8 is attached to the end portion of the card reader main body portion 2 in the Z1 direction. A CPU or the like for controlling the card reader 100 is mounted on the control substrate 8.

[0018] Antenna 4 communicates with card 10 in a non-contact manner to access the information of card 10. Thereby, card reader 100 reads and writes the information of card 10 via antenna 4. As shown in FIGS. 2 to 4, antenna 4 is mounted on flexible printed board 11. Flexible printed board 11 is electrically connected to control board 8. Antenna 4 is disposed inside cover member 3. Specifically, antenna 4 is disposed in internal space S of protruding portion 31. As shown in FIG. 4, when viewed from the X direction, antenna 4 is disposed so as to surround opening cylinder portion 36.

[0019] Spacer member 5 is made of a resin having translucency. As shown in FIGS. 2 and 3, spacer member 5 is disposed in internal space S from opening 320. Spacer member 5 includes a frame portion 51 that fits into opening cylinder portion 36 and extends in the X direction, a placement surface portion 52 that is connected to an end portion of frame portion 51 in the X1 direction and faces the X1 direction, and a holding portion 53 that holds imaging unit 7. Holding portion 53 is provided in the Y2 direction of frame portion 51 and placement surface portion 52. In this embodiment, frame portion 51 is a cylindrical shape extending in the X direction. As shown in FIG. 3, placement surface portion 52 is located in the X1 direction from case 201. Thereby, antenna 4 is located outside case 201.

[0020] Flexible printed board 11 is attached to placement surface portion 52. Thereby, antenna 4 is disposed on placement surface portion 52. Here, as shown in FIG. 5, a plurality of ribs 37 extending in the X direction are provided on the outer peripheral surface of opening cylinder portion 36. A positioning end portion 39 is provided inside protruding portion 31. In this embodiment, eight ribs 37 are provided. Positioning end portion 39 is provided continuously with the end portion of rib 37 in the X1 direction. When spacer member 5 fits into opening cylinder portion 36, the inner peripheral surface of frame portion 51 contacts rib 37, whereby spacer member 5 is positioned with respect to opening cylinder portion 36. That is, frame portion 51 is lightly press-fitted into opening cylinder portion 36. Further, when spacer member 5 fits into opening cylinder portion 36, placement surface portion 52 contacts positioning end portion 39, whereby spacer member 5 is positioned in the X direction. That is, frame portion 51 is lightly press-fitted into opening cylinder portion 36. Further, when spacer member 5 fits into opening cylinder portion 36, placement surface portion 52 contacts positioning end portion 39, whereby spacer member 5 is positioned in the X direction.

[0021] As shown in Figure 2, the rigid substrate 6 is a roughly rectangular flat plate with the Y direction as its longer side. The rigid substrate 6 is positioned between the flange portion 32 and the base plate 21 and closes the opening 320. Here, as shown in Figure 3, the spacer member 5 is sandwiched in the X direction between the rigid substrate 6 and the positioning end portion 39 provided on the inside of the protrusion 31. As a result, the spacer member 5 is fixed between the rigid substrate 6 and the cover member 3.

[0022] As shown in Figure 2, the rigid substrate 6 has a plurality of light-emitting elements 61 on its first surface 60 facing the X1 direction. The light-emitting elements 61 are LEDs and emit light toward the cover member 3. Three light-emitting elements 61 are mounted in the Z1 direction and the Z2 direction of the card passage opening 62 of the rigid substrate 6, respectively, aligned in the Y direction. In the Z1 direction and the Z2 direction of the card passage opening 62, the three light-emitting elements 61 are positioned at the center and both ends of the card passage opening 62 in the Y direction, respectively. The rigid substrate 6 is electrically connected to the control board 8 via the flexible printed circuit board 14. The light emission intensity of the light-emitting elements 61 is controlled by an LED control circuit mounted on the control board 8. As shown in Figure 4, when viewed from the X1 direction, the light-emitting elements 61 overlap with the protruding portion 31. Also, at least a portion of the light-emitting elements 61 does not overlap with the mounting surface portion 52 when viewed from the X1 direction. As a result, the light-emitting element 61 can irradiate light toward the front portion 34, illuminating the area around the insertion opening 30. Furthermore, since the spacer member 5 is translucent, the light irradiated from the light-emitting element 61 passes through the spacer member 5 and the opening cylindrical portion 36, illuminating the inside of the insertion opening 30 as well.

[0023] As shown in Figure 2, the imaging unit 7 is located on the front surface 34. The imaging unit 7 comprises a camera module 71 and a light-emitting unit 72. The imaging unit 7 is held by the holding unit 53 and housed inside the holding unit 38. The camera module 71 captures an image diagonally downward from an opening 382 provided on the front surface 381. The light-emitting unit 72 emits light diagonally downward from an opening 383 provided on the front surface 381.

[0024] A cover plate 16 is attached to the tip surface 381. The cover plate 16 is provided with a first light-transmitting portion 161 facing the camera module 71 and a second light-transmitting portion 162 facing the light-emitting portion 72. The first light-transmitting portion 161 and the second light-transmitting portion 162 are made of a transparent material. The entire cover plate 16 may also be made of a transparent material.

[0025] A flexible printed circuit board 12 is connected to the bottom of the camera module 71. The camera module 71 is connected to the control board 8 via the flexible printed circuit board 12. The camera module 71 images the one-dimensional or two-dimensional code attached to the card 10 via the first light-transmitting section 161.

[0026] The light-emitting unit 72 is a light-emitting element such as an LED. The light-emitting unit 72 is connected to the control board 8 via the flexible printed circuit board 13. The light from the light-emitting unit 72 is shone from the second light-transmitting unit 162 toward the card 10 which is positioned in the X1 direction of the cover plate 16.

[0027] (Effects and Benefits) The card reader 100 in this embodiment comprises a card reader body 2, a cover member 3 fixed to the card reader body 2 in the X1 direction, and an antenna 4 disposed inside the cover member 3 and communicating with the card 10 contactlessly to access the information on the card 10. The cover member 3 is inserted into a mounting hole 203 provided in the case 201 and is removed from the case 201 in the X1 direction. It comprises a protruding portion 31 that projects in the direction and a flange portion 32 that is connected to the end of the protruding portion 31 in the X2 direction and fixed to the mounting surface 202. The antenna 4 is located in the internal space S of the protruding portion 31.

[0028] In this configuration of the card reader 100, the antenna 4 is located in the internal space S of the protruding portion 31, so the antenna 4 is not located inside the case 201. As a result, when the antenna 4 communicates with the card 10 without contact, the antenna 4 is less affected by the case 201, and communication can be performed normally.

[0029] Antenna 4 is located outside the case 201 when viewed from the Y direction. This makes antenna 4 less susceptible to the influence of case 201 when communicating with card 10 wirelessly.

[0030] The card reader 100 includes a spacer member 5 positioned in the internal space S through an opening 320 formed in the flange portion 32. The antenna 4 is positioned on the placement surface portion 52 of the spacer member 5, which is provided in the X1 direction. This makes it easy to position the antenna 4 in the internal space S, which is spaced away from the flange portion 32 in the X1 direction.

[0031] The card reader 100 includes a rigid substrate 6 positioned between the flange portion 32 and the base plate 21 (first end) of the card reader body 2 in the X1 direction, which closes the opening 320. The spacer member 5 is sandwiched in the X direction between the rigid substrate 6 and a positioning end 39 provided inside the protrusion 31. This allows the spacer member 5 to be easily fixed by fixing the cover member 3 to the card reader body 2.

[0032] The protruding portion 31 comprises a front portion 34 with an insertion opening 30 for inserting the card 10 into the card reader body 2, an outer peripheral wall portion 35 extending in the X2 direction from the outer peripheral edge of the front portion 34 and connected to the flange portion 32, and an open cylindrical portion 36 surrounding the edge of the insertion opening 30 and protruding from the front portion 34 in the X2 direction. The internal space S is formed between the outer peripheral wall portion 35 and the open cylindrical portion 36. The antenna 4 is positioned to surround the open cylindrical portion 36 when viewed from the X direction. This allows the antenna 4 to be made larger even when an insertion opening 30 is formed in the front portion 34 of the protruding portion 31.

[0033] The spacer member 5 comprises a frame portion 51 that fits into the opening cylindrical portion 36 and extends in the X direction, and an arrangement surface portion 52 that is connected to the X1 end of the frame portion 51 and faces in the X1 direction. This makes it easy to position the spacer member 5 in the internal space S of the protruding portion 31, even when the cover member 3 is provided with an insertion opening 30.

[0034] Multiple ribs 37 extending in the X direction are provided on the outer circumferential surface of the open cylindrical portion 36. When the spacer member 5 is fitted into the open cylindrical portion 36, the inner circumferential surface of the frame portion 51 comes into contact with the ribs 37, thereby positioning it relative to the open cylindrical portion 36. This makes it easy to position the spacer member 5 relative to the open cylindrical portion 36.

[0035] The cover member 3 is made of a translucent resin. The rigid substrate 6 has a plurality of light-emitting elements 61 on its first surface 60 facing the X1 direction. When viewed from the X1 direction, the light-emitting elements 61 overlap with the protruding portion 31. At least a portion of the light-emitting elements 61 does not overlap with the arrangement surface portion 52 when viewed from the X1 direction. As a result, the light-emitting elements 61 can irradiate light toward the front portion 34, so that the area around the insertion opening 30 can be reliably illuminated.

[0036] The card reader 100 is located on the front 34 and includes an imaging unit 7 that images the primary or secondary code attached to the card 10. Therefore, the shape of the cover member 3 is less likely to become complex compared to the case where the imaging unit 7 is located in a different part from the front part 34.

[0037] (Embodiment 2) Figure 6 is an exploded perspective view of the card reader 100A of Embodiment 2. The card reader 100A of Embodiment 2 has the same configuration as the card reader 100 of Embodiment 1, except that it does not have an imaging unit 7. Therefore, in Embodiment 2, the same reference numerals are used for components that are the same as those in Embodiment 1, and their descriptions may be omitted.

[0038] The spacer member 5 is made of a translucent resin. The spacer member 5 is placed in the internal space S through the opening 320. As shown in Figure 6, the spacer member 5 comprises a frame portion 51 that fits into the opening cylindrical portion 36 and extends in the X direction, and an arrangement surface portion 52 that is connected to the end of the frame portion 51 in the X1 direction and faces in the X1 direction. Side wall portions 511 extending in the X direction are provided at both ends of the frame portion 51 in the Y direction. The side wall portions 511 are continuously connected to the arrangement surface portion 52. The central part of the flexible printed circuit board 11 is attached to the arrangement surface portion 52, and both ends in the Y direction are bent in the X2 direction and attached to the side wall portions 511. As a result, the antenna 4 bends in the X2 direction on both sides of the insertion opening 30 in the Y direction (longitudinal direction). As a result, by narrowing the width of the protruding portion 31 in the Y direction, it becomes possible to position the antenna 4 so as to surround the opening cylinder portion 36, even if the internal space S on both sides of the insertion opening 30 in the Y direction is narrowed.

[0039] (Other embodiments) The card reader 100 in the above-described embodiment had the function of accessing the information on card 10 by making contact with card 10 and reading and writing the information on card 10, as well as the function of accessing the information on card 10 by communicating with card 10 contactlessly and reading and writing the information on card 10. However, card readers in other embodiments may only have the function of accessing the information on card 10 by communicating with card 10 contactlessly and reading and writing the information on card 10.

[0040] While the card reader 100 in the above configuration accessed and read / wrote the information on card 10, card readers in other embodiments may simply access and read the information on card 10.
