Description of the Related Art Generally, two types of transport rollers of this kind are disposed so as to be rotatable vertically in a card transport direction, and a pair of endless belts are provided between the two pairs of transport rollers so as to be in contact with each other. It is stretched. When one of the belts is driven to travel, the other belt follows and travels. The card is conveyed by sandwiching the card between the two belts. At this time, if the pressure contact force between the belts is weak, the card cannot run at a stable speed. Therefore, one transport roller is brought into contact with the other transport roller with a strong pressure force.

ーラ２０が下方に付与される。In this manner, the wound portion 25 of the torsion coil spring 23 is elastically deformed in the direction of arrow A in FIG. 4 against the spring force of the torsion coil spring 23, and inserted through the opening 17a of one of the shaft bearing portions 15. Winding spring holding shaft 27
, And further into the U-shaped groove 18 of the other shaft bearing portion 16. Thereafter, when the pressing of the winding portion 25 in the direction A is released, the spring holding shaft 27 is pushed upward in the direction opposite to the direction of the arrow A, namely, upward by the restoring force of the torsion coil spring 23, and the U of the shaft supporting portions 15 and 16 is moved upward. They are pressed against the upper surfaces of the inner walls of the U-shaped grooves 17 and 18 and fixed to the shaft bearings 15 and 16. One end of the spring holding shaft 27 pressed against the upper surfaces of the inner walls of the U-shaped grooves 17 and 18 is engaged with the engaging surface 18a of the U-shaped groove 18, and the other end is engaged with the engaging portion 17a of the U-shaped groove 17. So
The spring holding shaft 27 is restricted from coming off the shaft bearings 15 and 16 in the axial direction. At the same time, the return force of the torsion coil spring 23 pushes the shaft 21 downward, so that the transport roller 20 is applied downward.

When the torsion coil spring 23 is further pressed, the spring holding shaft 27 is rotated.
5, the pressing of the transport roller 20 and the fixing of the spring holding shaft 27 can be performed at the same time, so that the assembly becomes easy. Moreover, the shaft holes 1 of the shaft bearings 15 and 16
By forming the U-shaped grooves 7 and 18 to open downward,
The spring holding shaft 27 can be easily inserted into the U-shaped grooves 17 and 18, and the inserted spring holding shaft 27 is regulated by the engaging portion 17 b, so that the spring holding shaft 27 is attached to the shaft support portions 15 and 16. Screws for fixing and fixing work are not required.

The upper surface and the lower surface of the bottom plate 11 of the upper housing 10 form a card transport path 30.
Is formed. At the same time, the lower portion of the transport belt 22 contacts the upper portion of the transport belt 7 and the transport roller 20 is pressed toward the transport roller 6 by the torsion coil spring 23.
The card is transported at a stable speed by the transport belts 7 and 22.

The present invention is not limited to this, and it is also possible to directly provide the bottom plate 11. Further, although the shaft holes 17, 18 of the shaft support portions 15, 16 are U-shaped grooves having openings at the lower side, they may be round holes or elliptical holes that are long in the vertical direction. Further, the locking projection 19 for locking the connecting portion 26 of the torsion coil spring 23 is provided. However, even when the connecting portion and the arm portion are in a substantially horizontal state, the return roller presses the transport roller 20 against the transport roller 6 side. If the torsion coil spring 23 having a force is selected, it is needless to say that a portion that simply locks the connecting portion does not need to be a convex portion, and various design changes are possible.

を同時に行うことができるので、組立が容易となる。As described above, according to the present invention, a torsion coil spring including a pair of arms, a pair of windings connected to the arms, and a connecting portion connecting the windings. A pair of bearing grooves for rotatably supporting the shaft of the conveying roller are formed on both side edges of the window on one of the conveying guide members forming the card conveying path, and connecting the torsion coil spring. A torsion coil spring formed between the locking portion and the bearing groove; and a pair of shaft support portions for supporting a spring holding shaft between the locking portion and the bearing groove. The arm of the bearing locks the shaft of the conveying roller from the opening side of the bearing groove, the connecting portion is locked to the locking portion, and the winding portion is rotated against the spring force of the torsion coil spring. By engaging the spring holding shaft supported by the bearing, the torsion coil By simply pressing the spring, the transport roller is temporarily fixed in the bearing groove, and when the torsion coil spring is further pressed, the spring holding shaft can be inserted into the winding part of the torsion coil spring. Can be simultaneously performed, so that the assembling becomes easy.

The provision of the engaging portion for restricting the movement in the axial direction makes it easy to insert the spring holding shaft into the shaft support portion, and the inserted spring holding shaft is engaged at both ends by the return force of the torsion coil spring. In addition, since the detachment is restricted by the engagement portion, screws and fixing work for fixing the shaft to the shaft support portion are not required, and the number of parts and the number of steps can be reduced.
