DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a shutter structure for a card processing device for preventing double insertion of cards during card transportation.

<Prior Art> Conventionally, there are various magnetic cards having a magnetic stripe as an information storage medium, and a card reader / writer for reading / writing information from / to such a magnetic card is carrying a card. In some cases, a shutter mechanism is provided to prevent the second card from being inserted twice. This shutter mechanism includes, for example, Japanese Patent Laid-Open No.
As disclosed in Japanese Patent Laid-Open No. 223853 and Japanese Utility Model Laid-Open No. 57-29958, there are known ones in which a shutter body is driven by a solenoid to selectively open and close an insertion port.

According to the above structure, the shutter mechanism is provided separately from the transport mechanism for transporting the card, and not only the number of parts such as the shutter body and the solenoid is large as described above, but also the mounting space for providing the shutter mechanism. However, there is a problem in that it is difficult to reduce the size.

<Problems to be Solved by the Invention> In view of the problems of the conventional art, a main object of the present invention is to provide a shutter structure for a card processing device which can be further downsized.

[Structure of the Invention] <Means for Solving the Problems> According to the present invention, such an object is to define a part of a transport path for guiding the insertion port and the information storage card toward the reader / writer unit. And a partially cylindrical transfer surface provided over a predetermined angle range so as to form a part of the transfer path, and rotatably provided near the insertion opening in the casing. A drum body, and an opposing pressing means provided in the casing for holding and transporting the card in cooperation with the transport surface, wherein the drum body, when the drum body rotates, The present invention is achieved by providing a shutter structure for a card processing device, which has a large-diameter portion provided over an angular range other than the transport surface of the drum body so as to block the transport path.

<Operation> In this way, by rotating the drum body in order to convey the card, the conveyance path is blocked by the large diameter portion provided in the drum body, so that only the drum body is being conveyed. It is possible to prevent the card from being repeatedly inserted, and it is not necessary to separately provide a shutter mechanism.

<Embodiment> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a sectional view of an essential part showing a guide unit of a card reader / writer as a card processing device to which the present invention is applied. As shown in FIG. 1, a part of a conveying path for guiding, for example, a magnetic card 4 as an information storage card inserted from an insertion slot 2 of a casing 1 of a guide unit toward a reader / writer section 9 described later. Insertion path 3
However, in order to prevent water from entering from the insertion port 2, it is formed so as to be inclined obliquely to the upper right in the figure. Inside the casing 1, a drum body 5 which is driven in a forward and reverse direction by a motor (not shown) is rotatably received. The drum body 5 extends from the upper portion in the figure to the clockwise direction in the figure for approximately half a circumference. In the same manner as described above, the transport guide portion 6 that forms a part of the transport path is formed so as to face the outer peripheral surface of the drum body 5 with a predetermined gap.

The drum pair 5 is divided into two halves by a partial arcuate conveying surface 5a extending over a predetermined angle range so as to form a part of the conveying path and a large-diameter portion 5b extending over the remaining angle range. The circumferential length of the arcuate transport surface 5a is formed to be slightly longer than the total length of the normal card 4 to be inserted.

Inside the casing 1, 2 facing the outer peripheral surface of the drum body 5
Rubber small-diameter conveyor roller 7 as a means for pressing each other individually
a and 7b are placed in the right places. That is, one conveying roller 7a is rotatably provided in the vicinity of the insertion slot 2, and the other conveying roller 7b is rotatably provided on the side of the reader / writer 9 having a known structure. Both of these conveying rollers 7a, 7b and the drum body 5
The card 4 is elastically held between it and the arcuate transport surface 5a, and the card 4 is transported as the drum body 5 rotates.
In addition, in the large-diameter portion 5b of the drum body 5, the circumferential groove 8 is provided as a relief for the above-mentioned respective conveying rollers 7a and 7b when the drum body 5 rotates.
Is recessed in the circumferential direction.

Further, detection sensors 10a and 10b, which are, for example, reflection type optical sensors, are disposed on the insertion port 2 side of the one conveyance roller 7a and the reader / writer 9 side of the other conveyance roller 7b, respectively. A magnetic head 11 for accessing the magnetic stripe of the card 4 is provided in the reader / writer section 9 provided below the casing 1 in the figure.

In the card reader / writer having the casing 1 configured as described above, before the card 4 is inserted, as shown in FIG.
The drum body 5 is stopped so as to block the transport path formed by the portion between the circular transport surface 5a and the arc-shaped transport surface 5a, and the step portion 5c that is the boundary between the arc-shaped transport surface 5a and the shutter portion 5b has the insertion port 2 It is designed to face. Therefore, even if a foreign object such as thin paper other than a normal card is inserted, the insertion can be prevented by the step portion 5c.

First, when the card 4 is inserted through the insertion slot 2, the front end of the card 4 is detected by the detection sensor 10a, and the drum body 5 starts rotating clockwise in FIG. 1 by a motor (not shown). Then, the card 4 is held between the arc-shaped transport surface 5a and the transport roller 7a, and the drum body 5 rotates, so that the transport guide portion 6 between the transport rollers 7a and 7b indicates the transport direction. The card 4 is changed downward and the card 4 is conveyed along the arcuate conveying surface 5a as shown in FIG. At this time, as shown in FIGS. 3 and 4, the card 4 is elastically sandwiched between the arcuate transport surface 5a and the transport rollers 7a, 7b, and the drum body 5 rotates as the card 4 rotates. The card 4 is conveyed. Then, as shown in FIG. 5, after passing through the transport roller 7b, the card 4 is guided toward the reader / writer unit 9 by being guided by the transport path 12.

When the optical sensor 10b detects that the rear end of the card 4 has passed, the driving of the motor is stopped and the rotation of the drum body 5 is stopped. In the reader / writer unit 9, the magnetic head 11 reads / writes information from / to the magnetic stripe of the card 4 while the card 4 is being conveyed by a conveying roller or the like. When the card 4 is ejected, it can be ejected by performing an operation reverse to the above.

The length in the conveyance direction between the two optical sensors 10a and 10b is the same as the full length of the normal card 4, and the rotation of the drum body 5 is started with the detection sensor 10a turned on and the detection sensor 10b turned off. , One of them is on, the drum body 5
Is continuously rotated, and the drum body 5 is controlled to stop rotating when both the detection sensors 10a and 10b are turned off.
That is, when a short card or the like is inserted, erroneous insertion of the card 4 while the card 4 is being conveyed by the drum body 5 can be detected and treated.

During the conveyance of the card 4 by the drum body 5, the portion of the conveyance guide portion 6 facing the insertion opening 2 side is blocked by the large diameter portion 5b of the drum body 5, so that the second card is conveyed during the conveyance of the card 4. It is impossible to insert the card, and it is possible to preferably prevent erroneous insertion of duplicate cards. As described above, the shutter mechanism can be configured by using the roller as the conveying means without separately providing the shutter body and the solenoid as the lock means for the shutter body, and the overall size of the card reader / writer can be further reduced.

In this embodiment, the inserted card is immediately changed in the conveying direction by the drum body 5 by about 90 degrees, and the depth of the casing can be reduced, but the card extends straight from the insertion port. Even in the case of a card reader / writer having a transport path, a part of the outer circumferential surface of the drum body may be exposed to a part of the transport path.

[Effects of the Invention] As described above, according to the present invention, while the card is being conveyed by the drum body as the card conveying means, the conveyance path can be blocked by the large diameter portion formed on the drum body, Even if the second card is inserted from the insertion slot during transportation, the insertion can be blocked by the large diameter part, and there is no need for a mounting space for providing a separate and independent shutter mechanism. For example, a card reader / writer as an apparatus can be easily miniaturized.
