[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a device for processing various cards such as a magnetic card, an IC card, and a card for both magnetic and IC, and in particular, dust intrusion from a card insertion port. The present invention relates to a shutter mechanism of a card processing device capable of preventing the above.

[Conventional technology]

Conventionally, as a shutter mechanism of a card processing device for reading and writing information recorded on a card such as a magnetic card or an IC card, one configured as shown in FIG. 5 is known. When this is roughly explained in the figure,
Reference numerals 1 and 2 vertically oppose each other to form a slit-shaped card insertion opening 4 that allows the insertion of one card 3. An upper plate and a lower plate 5 are provided in a recess 6 provided on the lower surface of the upper plate 1. Is a roller that normally closes the card insertion slot 4 by being pressed against the upper surface of the lower plate 2 by a spring 7 and this roller 5 has a length substantially equal to the width of the card insertion slot 4. About the card slot 4
This prevents dust from entering the housing. 8 is a drive roller, 9 is vertically movable and is pressed against the drive roller 8 when the card is conveyed, so that the driven roller 10 is a guide rail,
11 is an endless belt.

[Problems to be solved by the device]

By the way, in such a conventional shutter mechanism, the roller 5 normally closes the card insertion opening 4, and when the card is inserted, the roller 5 is pushed up against the spring 7 by the card 3 to open the card insertion opening 4. Since it is opened, dust can be prevented from entering, but in order to prevent insertion of a plurality of cards 3 or insertion of a thick card, the roller 5
In addition to the above, it is necessary to add a structure for regulating the thickness, and therefore, conventionally, the height dimension of the card insertion slot 4 must be set strictly, and in addition, the concave portion 6 is provided in the upper plate 1 to form a roller. Since the spring 7 must be housed together with the spring 5, the structure is complicated.

Therefore, the present invention solves the above problems,
An object of the present invention is to provide a shutter mechanism of a card processing device which can surely prevent dust from entering with a simple structure.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a support shaft disposed above the card intake passage and in the vicinity of the card insertion slot, and a predetermined shaft necessary for the support shaft to vertically pass through a single card. And a cylindrical shutter roller rotatably supported with play, the shutter roller being normally located at a lower position and abutting a card guide plate forming the card intake passage to close the card intake passage. However, when the card is inserted, it is pushed up by the card to open the card intake passage so as to allow the passage of one card.

[Action]

In the present invention, the shutter roller is rotatably supported by a support shaft so that it can move up and down with a predetermined play required for passing one card. Normally, the card insertion port is closed to prevent dust from entering. Allowing the passage of one card prevents the simultaneous insertion of multiple cards and the insertion of thick cards.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

FIG. 1 is a sectional view showing an embodiment of a card processing apparatus according to the present invention, and FIG. 2 is a sectional view taken along the line II-II in FIG. In these figures, a card processing apparatus generally designated by reference numeral 20 includes a front plate 21, a rear plate 22, and a pair of left and right side plates 23A and 23B.
A housing 24 formed in a box shape that is long in the front-rear direction, such that the front plate 21 is integrally provided with an insertion port member 25 having a card insertion port 4, and the insertion port member 25 has a front portion. A card guide plate 26 that penetrates through the face plate 21 and is inserted into the housing 24 is integrally extended. This card guide plate 26
Forms the same plane as the lower surface of the card insertion slot 4.

Inside the housing 24, there are provided a card taking-in passage 30, a card processing and conveying passage 31 and a card shunting passage 32 which are connected in series and extend substantially horizontally toward the rear.
The front end of the card intake passage 30 communicates with the card insertion slot 4. These passages 30, 31 and 32 are arranged on the inner surface of each of the side plates 23A and 23B so as to face each other with a predetermined space therebetween, and guide and hold each side end of the card 3. It is formed by a plurality of passage forming members 33.

At the upper front position of the card intake passage 30, that is, at a position close to the card insertion slot 4, the both side plates 23A, 23B are provided.
A support shaft 34 supported between the support shaft 34 and a shutter roller 35 rotatably supported by the support shaft 34 are arranged, and these constitute a shutter mechanism 36. Since the shutter roller 35 is formed in a cylindrical shape, it has a length substantially equal to the width of the card intake passage 30 as shown in FIG. 2, and its center hole 37 has the above-mentioned support as shown in FIG. 3 (a). The support shaft 34 is formed to have a diameter larger than that of the shaft 34.
It is vertically movable with respect to the card guide plate 26 and normally makes line contact with the upper surface of the card guide plate 26 to close the card intake passage 30.
The maximum gap G between the support shaft 34 and the central hole 37 is set to t <G <2t, where t is the thickness of the card 3. When the card 3 is inserted through the card insertion slot 4, its insertion end abuts against the peripheral surface of the shutter roller 35 and presses it, so that the shutter roller 35 is pushed up by the card 3 as shown in FIG. 3 (b). Then, the card intake passage 30 is opened. Therefore, the passage of the card 3 is allowed. In this case, if two cards 3 are inserted in a stacked manner, the above condition t <G <
With 2t, only the lower card can pass below the shutter roller 35, and the upper card can only pass through the shutter roller 35.
, And further insertion is blocked.

FIG. 4 shows another embodiment of the shutter mechanism 36.
The upper surface of the card guide plate 26 is provided with an arcuate recess 39 having substantially the same outer diameter as the shutter roller 35, and the lower surface of the shutter roller 35 is brought into surface contact with the recess 39. Assuming that the maximum gap G ₁ between the support shaft 34 and the central hole 37 is t and the maximum depth of the recess 39 is W,
t + W <G ₁ <2t + W is set. In such a configuration, the card take-in passage 30 is more reliably closed as compared with the line contact shown in FIG. 3, and the effect of preventing the intrusion of dust and the like is further increased.

A drive roller 8 and a driven roller 9 are vertically opposed to each other at the boundary between the card take-in passage 30 and the card processing / conveying passage 31, and a magnetic head 41 and a touch roller are provided in the card processing / conveying passage 31. Cards 42 are vertically opposed to each other with the card processing and conveying passage 31 interposed therebetween, and a card conveying means 43 for reciprocating the card 3 is arranged. The driven roller 9 is disposed below the normal driving roller 8 and is separated from the normal driving roller 8 by a predetermined distance. Then, the insertion end of the card 3 is pressed.

The card transport means 43 is a pair of endless belts 44 and 45 which are vertically opposed to each other with the card processing transport path 31 interposed therebetween.
And a plurality of pulleys 46a to 46f on which the belts 44 and 45 are respectively stretched, and the pulley 46a and the driving roller 8 are arranged on the same shaft 47. The drive roller 8 receives rotation transmission from a drive motor (not shown) at the time of card taking-in and carrying, and is rotated in the card carrying direction, so that the card 3 inserted in the card taking-in passage 30 is placed in the card processing carrying passage 31. Guide, magnetic head 41
After the series of processes such as the data reading and writing process is completed, the drive motor is switched in the rotation direction to rotate the card in the return direction, so that the card 3 is fed back and passed through the card loading passage 30 to insert the card insertion port 4 into the card insertion port 4. To return.

When the remaining value information of the first card becomes "O", the card saving passage 32 receives it from the card processing and conveying passage 31 and temporarily saves it so that an additional card can be used. In addition, the card transport means 51 is composed of a pair of upper and lower endless belts 48 and 49, and a plurality of pulleys 50a to 50d for stretching the belts 48 and 49.

Although the following embodiment shows an example in which the card 3 taken in the housing 24 from the card insertion port 4 is returned to the card insertion port 4, the present invention is not limited to this, and the card return port is inserted. It may be provided separately from the mouth 4, and it is not limited to the retractable card processing device capable of continuously processing a plurality of cards, but may be the one which does not have the card retract passage 32 and cannot continuously use the additional card. Of course, it can be implemented.

[Effect of device]

As described above, according to the shutter mechanism of the card processing apparatus according to the present invention, the cylindrical shutter roller is rotatably supported by the support shaft in the vertical direction with a predetermined play required for passing one card. , Ordinarily, the shutter roller is brought into contact with the upper surface of the card guide plate to close the card intake passage, and when the card is inserted, the shutter roller is pushed up by the card so that the card can be inserted. In order to reliably prevent dust and the like from entering the housing, and also to prevent the thick insertion of a thick card or a plurality of cards at the same time, the shutter roller has a thickness control function in addition to the dust prevention function.
