(Circuit configuration of the card reader 100)
FIG. 4 is an explanatory diagram showing a circuit configuration of the card reader 100 shown in FIG. As shown in FIG. 4, the following circuit is configured on the first circuit board 3 and the second circuit board 4 used in the card reader 100.

As shown in FIG. 4, the second circuit board 4 has a main control circuit 41 that controls the entire card reader 100, a motor drive circuit 42 that drives a motor for carrying the card C, and various power supplies.

As described above, in the card reader 100 of this embodiment, when performing contactless communication with the card C, a circuit for contactless communication and a circuit that is not used for contactless communication are mixedly mounted on one circuit board. That is, a magnetic demodulation circuit 33 and a position detection circuit 34 that are not used during non-contact communication are provided on the first circuit board 3 provided with the antenna 30 for non-contact communication, the antenna circuit 31, and the control circuit 32 for non-contact communication. A second circuit board 4 that is provided and different from the first circuit board 3 is provided with a main control circuit 41 that is used during non-contact communication.

It is explanatory drawing of the electrically conductive plate 9 in the state which made the space | interval the open state, and explanatory drawing of the electrically conductive plate 9 in the state which accumulated the 1st frame 1 and the 2nd frame 2. 6 is a perspective view of the structure for fixing the conductive plate 9 for countermeasure against static electricity to the bezel 210 in the card reader 100 shown in FIG. 1 as viewed from the side of the insertion port 21, and FIGS. 6 (a) and 6 (b) are views. FIG. 5 is an explanatory view showing a state before the conductive plate 9 is fixed to the bezel 210 and an explanatory view showing a state after the conductive plate 9 is fixed to the bezel 210. FIG. 7 is a perspective view of the structure for fixing the conductive plate 9 for countermeasure against static electricity to the bezel 210 in the card reader 100 shown in FIG. 1 as viewed from the side opposite to the insertion port 21, and FIGS. ) Is an explanatory view showing a state before the conductive plate 9 is fixed to the bezel 210, and an explanatory view showing a state after the conductive plate 9 is fixed to the bezel 210.

In the card reader 100 of this embodiment, when the card C is inserted into the insertion slot 21, if static electricity released from the hand enters the second circuit board 4, problems such as data corruption occur. Therefore, in this embodiment, as shown in FIGS. 1, 2 and 3, the second frame 2 is insulative, while the first frame 1 is conductive. A conductive plate 9 disposed between the insertion slot 21 and the second circuit board 4 is fixed to the second frame 2, and the conductive plate 9 is in contact with the first frame 1. In this embodiment, the insertion port 21 is formed in an insulating bezel 210 fixed to the end 20 on the insertion port 21 side of the second frame 2, and the conductive plate 9 is shown in FIGS. 5, 6 and 7. Then, as described below, it is fixed to the bezel 210 by screws 99 (see FIG. 1). For this reason, the conductive plate 9 is fixed to the second frame 2 via the bezel 210.

As shown in FIGS. 5, 6, and 7, the conductive plate 9 includes a strip-shaped flat plate portion 92 fixed to the bezel 210, and an arm extending rearward from the flat plate portion 92 (on the side opposite to the insertion port 21). Part 93 and a leaf spring-like contact part 95 bent downward from the arm part 93 (on the side of the first frame 1). The contact part 95 includes the first frame 1 and the second frame 2. When it overlaps, it contacts the first frame 1.

The bezel 210 is provided with a first receiving portion 211 facing in the Z direction and a second receiving portion 212 made of a wall orthogonal to the first receiving portion 211 at the end of the first receiving portion 211 on the insertion port 21 side. In addition, the first receiving portion 211 is formed with a cylindrical portion 214 in which holes 213 to which the screws 99 are fastened are opened at two locations separated in the Y direction. Further, a positioning convex portion 216 is formed at a position adjacent to the two cylindrical portions 214 on the outside.

On the other hand, in the conductive plate 9, the flat plate portion 92 is formed so as to overlap the second receiving portion 212. The conductive plate 9 is formed with a connecting portion 94 that overlaps each of the two cylindrical portions 214 between the flat plate portion 92 and the arm portion 93, and the connecting portion 94 has a hole 940 through which a screw 99 is passed. Is formed. In addition, a positioning hole 96 into which the convex portion 216 is fitted is formed at the base of the arm portion 93. Therefore, after the convex portion 216 is fitted into the hole 96 and the conductive plate 9 is positioned in the bezel 210, the conductive plate 9 is fixed to the bezel 210 with the screw 99, and then the bezel 210 is fixed to the end 20 of the second frame 2. Then, the conductive plate 9 can be fixed to the second frame 2.

Here, in a state where the second frame 2 is swung with respect to the first frame 1 by the hinge mechanism 110 described with reference to FIG. 3 and the like and the first frame 1 and the second frame 2 are opened. The contact portion 95 of the conductive plate 9 and the first frame 1 are separated from each other, but when the first frame 1 and the second frame 2 are overlapped and the engaging portion 17 is engaged with the engaged portion 27, The contact part 95 contacts the engaging part 17 with elasticity. In this embodiment, the engaging portion 17 is a convex portion protruding in a columnar shape toward the second frame 2, and the contact portion 95 is elastically in contact with the side surface 171 facing the insertion port 21 side in the engaging portion 17.

(Main effects of this form)
As described above, in the card reader 100 of the present embodiment, the first frame 1 is made conductive and the second frame 2 is made insulating, and the second frame 2 has an insertion slot 21 and a second circuit board. 4, a conductive plate 9 in contact with the first frame 1 is fixed. For this reason, when the card C is inserted, static electricity discharged from the hand can be released through the conductive plate 9 and the first frame 1. More specifically, on the side surface of the first frame 1, if the convex portion 19 formed in the vicinity of the engaging portion 17 is connected to the chassis or the like of a higher-level device such as an ATM device or an automatic payment machine, Static electricity discharged from the hand can be released to the chassis or the like of the host device via the conductive plate 9 and the first frame 1. Accordingly, even if the second circuit board 4 is not provided with a static electricity suppression circuit, it is possible to suppress the static electricity that has entered from the insertion opening side from entering the circuit board, and thus the influence of static electricity can be suppressed. . In addition, since only the first frame 1 of the first frame 1 and the second frame 2 needs to be conductive, the cost can be reduced.

In particular, in this embodiment, since the power circuit 43, the control circuit 41, the light emitting element 7, the LED drive circuit 47, and the like are mounted on the second circuit board 4, a space for providing a static electricity suppression circuit on the second circuit board 4 is secured. Even in such a case, according to this embodiment, the influence of static electricity can be suppressed. Further, in this embodiment, since the light emitting element 7 is provided in the vicinity of the insertion opening 21, it is necessary to provide the second circuit board 4 up to the vicinity of the insertion opening 21. Intrusion of static electricity into the circuit board 4 can be suppressed.

Also, the contact portion 95 of the conductive plate 9 contacts the first frame 1 when the first frame 1 and the second frame 2 overlap. For this reason, it is not necessary to fix the conductive plate 9 provided on the second frame 2 to the first frame 1. Therefore, when performing maintenance or the like, the first frame 1 and the second frame 2 are spaced apart from each other. It is easy to make the space between the frame 1 and the second frame 2 open. Therefore, maintenance and the like are easy. Further, since the contact portion 95 is elastically in contact with the first frame 1 when the first frame 1 and the second frame 2 are overlapped, the conductive plate 9 can be brought into a state of reliably contacting the first frame 1. .

Furthermore, the contact portion 95 elastically contacts the engaging portion 17 of the first frame 1 when the first frame 1 and the second frame 2 overlap each other. The portion where the engaging portion 17 is formed is a portion where the first frame 1 and the second frame 2 are surely approached when the first frame 1 and the second frame 2 overlap each other, such as vibration. This is a place where the first frame 1 and the second frame 2 are not easily separated even if the above is added. Accordingly, the conductive plate 9 can be reliably brought into contact with the first frame 1 and the state in which the conductive plate 9 and the first frame 1 are in contact can be maintained. Furthermore, the contact portion 95 elastically contacts the side surface 171 of the engaging portion 17 (convex portion) protruding in a columnar shape toward the second frame 2, so that the contact portion 95 is between the engaging portion 17 and the engaged portion 27. Even if there is some play in the Z direction, the conductive plate 9 can be reliably brought into contact with the first frame 1.
