Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] <Industrial Field of Application> The present invention relates to a card transport device for transporting a card between two positions.

<Prior art> Conventionally, for example, reading cards as information storage media having optical, magnetic, electronic, physical, or other forms of information storage means, such as IC storage cards with built-in IC storage elements, have been used. In a card reader/writer for writing, there are various types of devices for transporting cards.

For example, there is a device in which a card inserted into a casing is conveyed while being held between a driving roller and a driven roller that face each other. As shown in FIGS. 5 and 6, a drive roller 35 is provided on the upper frame 32 side of the casing 31 coaxially with a drive pulley 34 driven by a belt by a motor 33. 3
A driven roller 37 is provided on the 6 side. These driving rollers 35 and driven rollers 37 are arranged in pairs at a predetermined interval in the conveying direction of the card 38, and both driving rollers 35 are connected to transmission pulleys provided coaxially with each other. They are connected via a belt wound around 39.

According to the above structure, each pulley is rotatably supported around an axis parallel to the card transport surface, and in order to make the device thinner, it is necessary to make the outer diameter of the pulley as small as possible. However, if a pulley with a smaller diameter than the minimum pulley diameter for the belt is used, the durability of the belt will deteriorate, and if the minimum pulley diameter is ensured, it is difficult to make the device thinner. Furthermore, for example, when transferring information to and from the magnetic tape provided on the card while transporting the card, it is necessary to run the card at a constant speed as much as possible, and in order to obtain a large flywheel effect, it is necessary to However, it is not preferable to reduce the diameter of the pulley, and similarly to the above, there is a problem in making the pulley thinner.

<Problems to be Solved by the Invention> In view of the problems of the prior art, the main object of the present invention is to provide a card transport device that can be made thinner.

[Structure of the Invention] <Means for Solving the Problem> Such an object is to provide a card transport device for transporting a card between two positions, in which axes perpendicular to the transport surface of the card and parallel to each other are provided. a pair of pulleys rotatably supported on the respective pulleys, a belt wound around both pulleys, means for driving the belt in the longitudinal direction, and a part of the belt on the card conveying surface. To provide a card conveying device, comprising: a guide means that projects toward the card; and an opposing guide means that opposes a protrusion of the belt so as to cooperate with the belt to grip and convey the card. This is achieved by

<Function> In this way, since the pulley is rotatably supported around the axis perpendicular to the card conveying surface, the height of the device is not affected by the diameter of the pulley. It can be made thinner.

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

FIG. 1 is a plan view with the top surface of a casing 1 of a card conveyance device according to the present invention cut away;
2 is a side sectional view taken along the - line in FIG. 1, and FIG. 3 is a side sectional view taken along the - line in FIG. 1. The casing 1 is flat and box-shaped, which is long in the axial direction in the left-right direction in FIGS. 1 and 2, and the rear end surface on the left side in the figures is open. An insertion slot 3 for inserting a magnetic card 2, for example, is provided at the front end of the casing 1 on the right side in the drawing. The card 2 inserted through the insertion opening 3 passes between the mutually opposing inner surfaces of the top plate 4 and bottom wall 5 of the casing 1. A guide groove 6 is formed in the bottom wall 5 for receiving the card 2 and guiding both side edges of the card 2 in the conveyance direction.

A driving pulley 7 and a driven pulley 8 are provided on the side of the guide groove 6 of the bottom wall 5 at a predetermined interval in the conveying direction of the card 2. Both of these pulleys 7 and 8 have the same diameter and are provided with shafts 7a and 8a that stand on the bottom wall 5, respectively.
The card 2 is rotatably supported around an axis perpendicular to the conveying surface of the card 2. A belt 9 made of a rubber material and having a circular cross-section, for example, is wound around both pulleys 7 and 8, and a straight section 9a of one of the belts extends along the conveying direction of the card 2 and along the guide groove 6. It is meant to be faced within.

A bridge-shaped mounting bracket 11 is provided inside the casing 2 on the drive pulley 7 side so as to cross over the drive pulley 7. A large-diameter gear 12 is fixed to the protruding end of the rotating shaft that protrudes above the mounting bracket 11 of the drive pulley 7. The large diameter gear 12 meshes with an idle gear 13 rotatably supported on the upper surface of the mounting bracket 11.
A small-diameter drive gear 15 of a flat motor 14 fixedly attached to the lower surface of the motor is engaged with the motor.

Above the straight portion 9a of the belt 9 in the vicinity of both pulleys 7, 8, a pair of guide rollers 17 are provided which are pivotally supported by brackets 16 that are fixedly installed to hang down from the top plate 4, respectively. There is. As best shown in FIG.
A straight portion 9a, which is a part of the card 2, is guided by both guide rollers 17 so as to protrude toward the bottom surface of the guide groove 6, which serves as a conveyance surface for the card 2.
Further, a driven roller 18 is provided so as to face into the casing 1 through openings formed in the bottom wall of the guide groove 6 at positions facing both guide rollers 17, respectively. The driven roller 18 is rotatably supported by the free end of a leaf spring 19 whose base end is fixed to the lower surface of the bottom wall 5, and is guided by the guide roller 17 of the straight portion 9a of the belt 9. The bullet is biased towards the part that is exposed.

Further, a guide plate 20 is fixed in the casing 1 and extends from the insertion opening 3 to the vicinity of the bracket 16 so as to cover the upper surface of the guide groove 6 on the side opposite to the belt 9 side along the conveyance direction. . Insertion port 3
One side edge of the card 2 inserted from the guide plate 20 is received between the guide plate 20 and the bottom surface of the guide groove 6, and is positioned in the vertical direction.
The side edge of the bracket 16 of the guide plate 20 is provided with information read/write information for the magnetic tape section 23 of the card 2.
As shown in FIG. 4, a magnetic head 21 for writing is fixedly installed so as to face inside the guide groove 6. The magnetic head 21 is mounted on the bottom wall of the guide groove 6 by, for example, a leaf spring. A pressing pad 22 is provided which is resiliently biased toward the pressing pad 21.

In the card transport device configured in this way, when the card 2 is inserted from the insertion slot 3,
For example, a sensor (not shown) is actuated to rotate the flat motor 14 and drive the drive pulley 7 in the direction of the arrow in FIG. Then, the leading end of the card 2 is elastically clamped between the straight portion 9a of the belt 9 and the driven roller 18 on the side of the insertion slot 3, so that the card 2 is transported toward the rear end of the casing 1. I can do it. Furthermore, as shown by the imaginary line in FIG. 2, the card 2 is also held and conveyed between the straight portion 9a of the belt 9 and the driven roller 18 on the left side of the figure. Then, as shown in FIG. 4, the magnetic tape part 23 of the card 2 pressed against the magnetic head 21 side by the pressing pad 22 is pressed.
The magnetic head 21 reads/writes information. Furthermore, after reading/writing information,
Reverse the flat motor 14 and insert the card 2 into the insertion slot 3.
Card 2 can be taken out by returning it towards.

In this way, the drive pulley 7 is rotated about the axis perpendicular to the conveying surface of the card 2.
By pivotally supporting the driven pulley 8, the height of the card conveying device is not affected by the pulley diameter, so the device can be suitably made thinner. Further, a pulley with a relatively large diameter can be used, and the transport speed of the card 2 can be easily stabilized by a sufficient flywheel effect. Furthermore, by using the flat type motor 14 as the motor for driving the drive pulley 7, the casing 1 can be easily made thinner than, for example, when a cylindrical type motor is used. Although a round belt is used in this embodiment, the cross-sectional shape of the belt 9 is not limited; for example, a belt having a rectangular cross-sectional shape can be used.

[Effects of the Invention] As described above, according to the present invention, by supporting the pulley rotatably around the axis perpendicular to the card conveying surface, the height of the device does not affect the diameter of the pulley. Therefore, the device can be made thinner. In addition, a pulley with a relatively large diameter can be used, and the running of the card can be stabilized by a large flywheel effect, which is extremely effective.
