2. Description of the Related Art In general, a card transport apparatus of this kind has a pair of upper and lower endless belts stretched between a driving roller and a driven roller disposed at both ends thereof, and the card is held between the upper and lower endless belts. As a result, the sheet is conveyed along with the movement of the conveying belt. in this case,
When the transport belt is relatively short, the card is pressed against the transport belt only by the drive roller and the driven roller, but when the transport belt is long, the transport belt is insufficiently pressed at the intermediate portion of the transport belt, The card and the belt slip, making it impossible to carry the card.

Therefore, in the related art, a pair of conveying rollers are opposed to each other between a driving roller and a driven roller as necessary, and the conveying belt is also pressed by pressing these conveying rollers. As the pressure contact structure of the transport roller, a method of simply supporting the upper and lower rollers,
There has been a method in which the upper and lower rollers are biased by a spring in a direction in which they are pressed against each other.

[0004]

However, in the method of simply supporting the upper and lower rollers, the supporting position of the upper and lower transport rollers must be accurately adjusted so that the card and the transport belt do not slip. Therefore, there is a disadvantage that the adjustment takes time. Also, in the method of urging the upper and lower rollers, springs must be provided at both ends of each roller shaft, which increases the number of parts, takes time to assemble, and increases costs. was there.

Accordingly, the present invention has been made in view of the above-mentioned drawbacks of the related art, and it is an object of the present invention to provide a card transport device which requires no adjustment and is easy to assemble.

Next, using the lever 50 configured as described above, the transport rollers 31 and 32 are moved downward by the transport rollers 33 and
A method of assembling the structure for pressing against 34 will be described. The two levers 50 are opposed to each other, and the dowels 56 are fitted into the long groove 57 and joined. The U-shaped groove 54 of the coupled lever 50 is loosely fitted to the fixed shaft 49 as shown in FIG.
The lever 50 is swingable about the fixed shaft 49. Then, a coil spring 60 is hung on a spring latching portion 58 of both levers 50, and the coil spring 60 is hung on a spring latching piece 59, and the left and right levers 50 are fixed to the fixed shaft 4.
9 is imparted with rotation behavior in the counterclockwise and clockwise directions, respectively, and at the same time, the U-shaped grooves 55 are loosely fitted to the shafts 45 and 46, and the transport rollers 31 and 32 are transport rollers 33 and
Pressure contact.

As described above, the U-shaped grooves 54 of the levers 50 which are coupled to face each other are loosely fitted to the fixed shaft 49,
Since the fixed shaft 49 is used as a supporting point and the coil spring 60 is hung on the spring retaining portion 58 and the spring retaining piece 59, the shafts 45 and 46 are pressed from above by the U-shaped groove 55, so that the assembly is easy. Since the two transport rollers 31 and 32 can be incorporated at the same time, work efficiency is improved. Pressing is performed by the coil spring 60,
Since both ends of the shafts 45 and 46 of the transport rollers 31 and 32 are pressed by the U-shaped grooves 55 formed on both side plates 51 and 52 of the lever 50, the transport rollers 31 and 32 can be pressed uniformly to the left and right. No adjustment is required. Further, since the levers 50 are used facing each other, the same parts can be used, and the number of parts does not increase.

When the card 6 is inserted into the card transport path 4 from the card insertion slot 5 in the press-contact structure of the transport rollers assembled as described above, a motor (not shown) rotates, and this rotation is transmitted to the drive roller 25. Then, the endless belt 23 moves. The endless belt 24 pressed against the endless belt 23 also moves, and the card 6
4 and transported so as to be taken into the card transport path 4. At this time, the upper conveying rollers 31, 3
Since 2 is pressed against the lower conveying rollers 33 and 34, card conveyance by the endless belts 23 and 24 is performed stably without slipping. The card 6 removes noise written on the card 6 by the AC head 14, performs read / write by the read / write head 11,
The noise is written by the head 14 and returned from the card insertion slot 5.

FIG. 5 shows a second embodiment of the present invention. In this embodiment, an L-shaped cut-and-raised piece 61 is provided on the upper surface plate 53 of the lever 50. A leaf spring 62 that is slightly longer than the interval between the both raised and cut pieces 61 is interposed between the raised and cut pieces 61, and both levers 50 move around the fixed shaft 49 by the elastic force of the leaf spring 62. Rotational behavior is given in a counterclockwise direction and a clockwise direction, respectively, so that the upper transport rollers 31 and 32 can be replaced with the lower transport rollers 33 and 34.
Press against Note that the leaf spring 62 may be attached to the upper surface plate 53 with a screw.

[0018]

As described above, according to the present invention, a U-shaped groove is formed at the lower end at one end and the lower end at the other end of a pair of side plates facing each other. The side plate has a pair of levers each having a long groove provided at a position facing the protrusion on the other side plate,
The two levers are opposed to each other, and the projection is fitted into the long groove. The U-shaped guide at one end is loosely fitted to the fixed shaft to support the two levers swingably about the fixed shaft, and the other end is provided at the other end. One endless bell in each of the U-shaped grooves
The transport shaft of the transfer roller is loosely fitted, and this lever is
The transport roller of one endless belt is the other endless belt.
There is provided an urging means for imparting rotation in a direction in which the levers are pressed against the conveying rollers of the levers. By simply attaching the urging means, the other U-shaped groove presses the transport roller, which facilitates installation and maintenance, and furthermore, since two transport rollers can be incorporated simultaneously, the work efficiency is improved. I do. Further, since the pressing is performed by a spring and both ends of the shaft of the conveying roller are pressed by the U-shaped grooves of the both side plates of the lever, the conveying roller can be uniformly pressed right and left, and no adjustment is required. Furthermore, since the levers are used facing each other, the same parts can be used, and the cost can be reduced without increasing the number of parts.
