A driven roller 37 is provided on the lower frame 36 side. These driving rollers 35 and driven rollers 37 are arranged in pairs at a predetermined interval in the conveying direction of the card 3B, and both driving rollers 35 are connected to transmission pulleys 39 coaxially provided on each of them. They are connected via a wound belt.

According to the above structure, each arm is rotatably supported around an axis parallel to the card transport mechanism.d) In order to make the device thinner, the outer diameter of the pulley is made as small as possible. There is a need. However, if a pulley with a diameter smaller 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. In addition, for example, when transferring information to and from a magnetic tape attached to a card while transporting the card, it is necessary to move the card at a constant speed, which requires a large flywheel effect. In order to achieve this, it is not preferable to reduce the diameter of the pulley, and there is a problem in making the pulley thinner, similar to the above.

A card conveying device characterized in that it has a guide means provided at the belt, and an opposing guide means opposed to the protrusion of the straight portion so as to cooperate with the belt to grip and convey the card. This is achieved by The present invention also provides a card conveying device for conveying a card between two positions, the device being rotatable around mutually parallel axes that are perpendicular to the card conveying direction and obliquely inclined with respect to the card conveying surface. a pair of pulleys pivotally supported by a pair of pulleys, a belt wound around both pulleys, a means for driving the belt in the longitudinal direction, and a means for driving the belt to grip and transport the card. The card conveying device may include an opposing guide means facing the linear portion of the bell on the surface side.

In particular, an annular elastic body protruding toward the card carrying surface is solidly layered on the peripheral edge of a pulley rotatably supported around an axis obliquely inclined with respect to the card carrying surface. Good.

<Function> In this way, the height of the device is not affected by the diameter of the pulley, so the device can be made thinner, and the straight line of the belt wound around the inclined pulley can be reduced. Since it is possible to start conveying the card from the boundary with the section, the distance between both pulleys can be shortened. Furthermore, by tilting both pulleys together, the distance between both pulleys can be further shortened. In addition, by fixing the annular elastic body that protrudes in the direction C) toward the card conveyance surface on the peripheral edge of the pulley, the angle of inclination of the pulley can be reduced, and the influence of the inclination of the pulley on the height of the device can be reduced. - I can do something.

On the side of the guide groove 6 of the bottom wall 5, drive pulleys 7 having the same diameter are provided at a predetermined interval in the direction of conveyance of the card 2.
and a driven pulley 8 are provided. The drive pulley 7 is
A shaft 7 a provided to stand on the bottom wall 5 4. , T so that the driven pulley 8 is rotatable about an axis perpendicular to the conveying direction of the card 2, and the driven pulley 8 is rotated perpendicularly to the conveying direction of the card 2 by a shaft 8b provided on the bottom wall 5. Each of them is supported by a shaft so as to be inclined obliquely to the conveyance surface. A belt 9 made of, for example, a rubber material having a circular cross-section is wound around both the shields 8, and a straight section 9a of one of the belts extends along the conveying direction of the card 2 and inside the guide groove 6. It is designed to face the situation.

1 is provided. Mounting bracket 1 for drive pulley 7
A large-diameter gear 12 is accommodated in the protruding end of the rotating shaft 1 that protrudes upward. Mounting bracket 11 for large diameter gear 12
It meshes with an idle gear 13 rotatably supported on the upper surface, and a mounting bracket 1 is attached to the idle gear 13.
A small-diameter drive gear 15 of an unbalanced type gear 14 fixedly attached to the lower surface of the gear 1 is engaged with the drive gear 15.

The boundary between the portion of the belt 9 wound around the driven pulley 8 and the above-mentioned straight portion 9a protrudes into the guide groove 6 as shown at -C in FIG. A guide roller 17 is provided above the straight portion 9a of the belt 9 in the vicinity of the drive pulley 7, and is pivotally supported by a bracket 16 to a racket 1 fixed to the top plate 4 so as to hang therefrom. As clearly shown in FIG. 2, the straight portion 9a of the belt 9 is kited by the driven pulley 8 and the kite roller 17 so that it protrudes into the kite groove 6, which serves as the feeding surface of the card 2. ing. Also, the belt 0 wound around the driven pulley 8
The driven roller 1B faces the inside of the casing 1 through the bottom wall of the guide groove 6 (J) so as to face the boundary of the straight portion 9a and the guide roller 17, respectively. ing.

The driven roller 18 is rotatably supported by a free spring portion of a temporary spring 19 whose base end is fixed to the lower surface of the bottom wall 5, and is elastically moved toward the straight portion 9a of the belt 9. energized.

Furthermore, a guide plate 20 that reaches from the insertion opening 3 to the vicinity of the bracket 16 is fixedly installed in the casing 1 so as to cover the soil surface on the opposite side of the guide groove 6 from the belt 9 side along the conveyance direction. There is. One side edge of the card 2 inserted through the insertion slot 3 is received between the guide plate 20 and the bottom surface of the guide groove 6, and is positioned in the downward direction. At the end of the guide plate 20 on the plug 16 side, there is a magnetic head 21 for reading/writing information from/to the magnetic tape section 23 of the card 2, as shown in FIG. , is fixedly installed so as to face inside the guide groove 6,
A suppression pad 22 is provided on the bottom wall of the guide groove 6, and is elastically biased by a plate spring having the same number as the magnetic head 21, for example.

In the card conveyance device configured as above, when the card 2 is inserted from the insertion slot 3, a sensor (not shown) is activated, the flat motor 1 is rotated, and the drive pulley 7 is rotated. It is driven in the direction of the arrow in Figure 1. Then,
The part of the belt 9 wound around the driven pulley 8 and the straight part 9
Since the leading end of the card 2 is elastically clamped between the boundary with the card 2 and the opposing driven roller 1B, the card 2 can be conveyed toward the rear end of the casing 1. 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 suppression pad 22 causes the magnetic head 21 to

The magnetic head 21 reads/writes information. After reading/writing information, the card 2 can be removed by reversing the flat card 15 and returning the card 2 to the insertion slot 3.

In this way, by pivotally supporting the driving pulley 7 and the driven pulley 8 so as to rotate around the axis in the direction intersecting the conveying surface of the card 2, the height of the card conveying device can be increased.
Since it is not affected by the pulley diameter, the device can be suitably made thinner. Furthermore, 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 motor 14 as the motor for driving the drive pulley 7, the device can be easily made thinner than, for example, when a cylindrical motor is used.

Further, as shown in FIG. 6, by fixing the annular elastic body 24 that protrudes toward the conveying surface of the card 2 to the peripheral edge of the driven pulley 8, the annular elastic body 24 and the driven roller 18
As a result, the card 2 can be held and conveyed from the driven boob 98 in the same way as in the embodiment described above. By doing so, the card 2 can be conveyed without increasing the inclination angle of the axis of the driven boob 98 so much, which improves the slimness of the device.

Further, as shown in FIG. 7, the driving pulley 7 may be provided at an angle with respect to the conveying surface of the card 2 so as to be parallel to the axis of the driven pulley 8.

In this case, each gear 12, 13 in the first embodiment
By meshing gears 25, 26, and 27, which correspond to and 15 and are, for example, bevel gears, with each other, the driving force from the flat upper and lower gears 14 can be transmitted to the drive pulley 7.

Incidentally, contrary to the first embodiment, even if only the drive pulley 7 is tilted with respect to the card 2 conveying surface, the problem will occur. Furthermore, the above-described annular elastic body 24 may be provided on the drive pulley 7.

Although a round belt was used in this embodiment, belt 9
The cross-sectional shape of the belt is not limited, and 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, the device can be made thinner without being affected by the diameter of the pulley, and a relatively large diameter pulley can be used, resulting in a large flywheel effect. This makes it possible to stabilize the running of the card.

Further, since the card can be conveyed from the boundary with the straight portion of the belt wound around the inclined pulley, the distance between the two pulleys can be shortened. Furthermore, by tilting both pulleys together, the distance between both pulleys can be made shorter, and the casing can be made more compact. In addition, by hardening the annular elastic body that protrudes toward the card conveyance surface on the peripheral edge of the pulley, the angle of inclination of the pulley can be reduced, so the influence of the inclination of the pulley on the height of the device can be reduced. The effects are extremely large, such as being able to make the device even thinner.
