The mounting plate 48 is fixed by screwing both side parts 48a, 48b bent downward to the side plate parts 21, 22 of the lower substrate 20. Two pairs of opposing support pieces 49, 50 are provided upright on the mounting plate 48.

A transmission lever 51 extending along the card insertion direction is supported by the pair of support pieces 49. The central portion 51a of the transmission lever 51 is laterally penetrated by the support shaft 52 locked between the support pieces 49 along the width direction of the card to be inserted, so that the support lever 52 can rotate about the support shaft 52. It is supported.

A roller 53 as an abutting portion of this embodiment is attached to the tip end portion 51 b of the transmission lever 51, and this roller 53 penetrates the square hole 46 of the upper substrate 40 and the lower substrate 20. The peripheral surface is in contact with the edge of the flat plate portion 23. The rear portion of the transmission lever 51 is bent in a crank shape, and a pressing roller 54 is rotatably attached to the rear end portion 51c.

The transmission lever 51 is always urged by a spring 55 attached to the support shaft 52 so as to lower the tip portion 51a.

A shutter plate 56, which serves as a shield in this embodiment, is supported on the other pair of support pieces 50 of the mounting plate 48. A pair of opposing mounting pieces 57 are provided upright on both sides of the central portion 56a of the shutter plate 56 extending along the card insertion direction, and the mounting pieces 57 and the supporting pieces 50 of the mounting plate 48 are The shutter plate 56 is supported so as to be rotatable about the support shaft 58.

The shutter plate 56 has a front end portion 56 b, which is located at a position rearward of the roller 53 of the transmission lever 51, and is formed in a gap between the cutout portions 24 and 41 of the lower substrate 20 and the upper substrate 40. It is extended downward so as to block (the part with a large gap).

The pair of guide portions 60b and 60c formed so as to face each other by the protruding portions 25a, 25b, 42a and 42b of the lower substrate 20 and the upper substrate 40 are the central portion 60a of the card insertion slot. Continuing with both ends of the card, the card is guided to the central portion 60a of the card insertion slot while restricting the movement of the inserted card in the width direction.

The rear portion 56c of the shutter plate 56 is formed higher than the central portion 56a, and extends below the roller 54 of the transmission lever 51 with a slight gap.

The shutter plate 56 is constantly urged by a spring 59 attached to the support shaft 58 in a direction in which the tip portion 56b is lowered.

Incidentally, reference numerals 61 and 62 in the drawing denote mounting pieces projecting downward on one side surface side of the upper substrate 40, and concave portions 63 and 64 provided in front and rear portions of the side plate portion 21 of the lower substrate 20, respectively. To be screwed from the side.

Further, the locking piece 65 projecting in the middle of the mounting pieces 61, 62 and the locking piece 66 projecting on the other side surface side are substantially central portions of the side plate portions 21, 22 of the lower substrate 20. The upper substrate 40 is prevented from floating with respect to the lower substrate 20 by non-reactively engaging with the engaging portions 67 and 68 (not shown) provided on the lower substrate 20.

Next, the operation when the card reader 18 is attached so that the guide portions 60b and 60c project from the operation panel 70 of the public telephone as shown in FIG. 5 will be described.

Note that FIG. 5 is a view in which a cover body for protecting the guide portions 60b, 60b of the card reading device 18 protruding forward from the operation panel 70 is omitted.

When the predetermined card 80 is inserted toward the central portion 60a of the card insertion slot while the widthwise movement of the card 80 is restricted by the guide portions 60b and 60c, the leading end portion 80a of the card 80 is pressed against the pressing roller 44 and the magnetic head. 26, and when the card 80 is further inserted, the front end portion 80a thereof abuts on the peripheral surface of the roller 53, and the roller 53 moves along the card thickness direction in a distance corresponding to the card thickness. Only pushed up.

Therefore, the rear end portion 51c of the transmission lever 51 is lowered, and the pressing roller 54 pushes the rear portion 56c of the shutter plate 56 downward.

As a result, the front end portion 56b of the shutter plate 56, which has closed the central portion 60a of the card insertion opening, moves upward, and the card insertion opening is fully opened.

Therefore, the card 80 is inserted until the tip portion 80 a of the card 80 contacts the stopper 28, and the micro switch 35 on the lower surface side of the lower substrate 20 is turned on.

Here, when the rear end portion 80b of the card 80 protruding from the card insertion slot is pulled out, the magnetic information stored in the card 80 is read by the magnetic head 26, and this information is read from the printed circuit board 36 to the public telephone. It is sent to the central office via the line, is processed for confirmation, and the public telephone can be used.

When the card 80 is pulled out, the transmission lever 51 returns to its original state by the urging force of the spring 55, and the shutter plate 56 also returns to its original state in response to the operation of this transmission lever 51, and the card insertion slot The central portion 60a is closed again.

In this state, even if a coin is to be inserted into the central portion of the card insertion slot, it is blocked by the tip portion 56b of the shutter plate 56, and foreign matter such as coins cannot be inserted.

Further, as described above, since there is a gap between the pressing roller 54 and the rear portion 56c of the shutter plate 56, even if a foreign matter thinner than the regular card passes through the roller 53, the pressing roller 54 will not move. The rear portion 56c of 56 cannot be pushed, the shutter does not open, and the entry of this thin foreign matter is blocked.

Further, since the gap between the guide portions 60b and 60c continuous to both end portions of the card insertion slot is only slightly larger than the thickness of both side portions of the card 80, it is easy to insert coins or the like into the guide portions. I can't do it.

In the above-mentioned embodiment, the card is brought into contact with the contact portion provided at a position close to one of the guide portions to operate the shield portion, but the above-mentioned embodiment is provided at positions close to both guide portions. Such a mechanism may be provided, and by doing so, it is possible to prevent erroneous insertion of a foreign substance narrower than the regular width and intentional insertion.

Further, in the above-described embodiment, the present invention is applied to the card reading device that reads information from the card by manual operation, but the present invention is not limited to the manual card reading device and the card can be automatically read. The present invention can be similarly applied to a card reading device that is inserted into and removed from the card, and can be configured separately from the card reading device.

[0048]

[Effect of device]

 As described above, in the card receiving mechanism of the present invention, when the card guided by the pair of guide portions comes into contact with the contact portion provided at a position close to at least one of the guide portions, this contact portion causes the thickness of the card to increase. The card moves in the vertical direction, and the shield part that is connected to this contact part opens at least the part that blocks at least a part of the card insertion slot at the position behind the contact part between the contact part and the card. Is configured to enter.

Therefore, it is possible to reliably prevent erroneous insertion and intentional insertion of foreign matter such as coins, and prevent damage to the card reading device and the card itself.
