A slit-shaped card insertion / ejection port 7 extending in the horizontal direction is formed substantially at the center of the front part 2 in the height direction. The width of the card insertion / exit slot 7 is regular. The magnetic card 8 is formed to be slightly larger than the width of the magnetic card 8, and the height thereof is formed slightly larger than the thickness of the regular magnetic card 8 that is stacked two times, so that the height is the same as the bottom 4. It is positioned. In addition, FIG.
As shown in FIG. 1, a pair of left and right long holes 9 and 9 (one is omitted in the drawing) are formed. A pair of protrusions 10 and 10 (one is not shown) are provided on both ends in the left-right direction of the surface of the bottom 4.
Are formed, and the pair of projections 10, 10 are positioned corresponding to a pair of card gauge members 21, 21 described later.

The rear portion 3 is provided with a card insertion opening 11 corresponding to the above-described card insertion opening / ejection opening 7 and having the same external dimensions as the above, and a pair of right and left recesses 12 and 12 are provided at the upper portion. Formed on the inner surface, a pair of left and right engaging portions 1
3, 13 are protruded. Reference numeral 15 denotes a U-shaped bracket in a plan view, and a pair of right and left screw holes 17, 1
7 are formed, and both ends of the support shaft 19 are press-fitted and fixed to the support holes of the left and right side portions 18, 18.
It is laid between 18 Card insertion member 1 described above

[0007] As shown in FIG.
A pair of torsion coil springs are wound around the lower end of the card gauge member 21 and the other end of the torsion coil spring 27 is
2, the card gauge member 2
1 is urged in the counterclockwise direction in FIG. Therefore, in the card gauge member 21, the protrusion 25 is always engaged with the inner surface of the rear portion 3 of the card insertion member 1, and the blocking portion 23 is spaced apart from the protrusion 10 of the card insertion member 1 by a small distance D. Opposed, a gap 28 is formed. The interval D of the gap 28 is equal to that of the regular magnetic card 8.
And is formed so as to be slightly larger than the thickness of one regular magnetic card 8 and to be smaller than the thickness of a regular magnetic card 8 in which two sheets are stacked or a magnetic card having a tape or the like adhered to the regular magnetic card 8. Have been. Therefore, one regular magnetic card 8 can pass through the gap 28,
The gap 28 functions as a so-called gauge part because the passage of a magnetic card having a tape or the like adhered to the two magnetic cards 8 or the regular magnetic card 8 is prevented.

In such a structure, as shown in FIG. 7A, when one regular magnetic card 8 is inserted from the card insertion / ejection port 7 of the card insertion member 1, as described above, Since the gap D between the blocking portion 23 of the card gauge member 21 and the projection 10 of the card insertion slot member 1 is formed slightly larger than the thickness of one regular magnetic card 8, one The regular magnetic card 8 passes through the gap 28. On the other hand, when a tape or the like is attached to a magnetic card that has been stacked two times or a regular magnetic card, and a magnetic card having an overall thickness greater than that of the regular magnetic card is to be inserted from the card insertion / ejection port 7, these magnetic cards are The magnetic card comes into contact with the blocking portion 23, and the card gauge member 21

As shown in FIG. 7 (b), two magnetic cards 8A and 8B taken in a card reader (not shown) are superimposed on each other so that the card insertion port 11 of the card insertion member 1 is inserted. When the magnetic card 8A is ejected, the upper magnetic card 8A comes into contact with the blocking portion 23 of the card gauge member 21, and rotates the card gauge member 21 clockwise in the drawing against the urging force of the torsion coil spring 27. For this reason, the chamfered portion 24 of the card gauge member 21 faces the projection 10 of the card insertion member 1 and opens the gap 28, so that the two magnetic cards 8A and 8B stacked on each other can be used as the card insertion / ejection port 7. Is discharged from

[0010]

However, in the structure of the conventional card insertion member described above, the through hole 22 of the card gauge member 21 is rotatably supported by the support shaft 19, so that the through hole is formed. A clearance is required between the shaft 22 and the spindle 19. For this clearance, when the bracket 15 incorporating the support shaft 19 and the card gauge portion 21 is assembled to the card insertion slot member 1,
The interval between the left and right gaps 28 tends to vary, and a predetermined interval D cannot be obtained, and an adjustment for setting the interval of the gap 28 to the predetermined interval D is required. That is, the bracket 15 is temporarily fixed to the card insertion slot member 1 with the screw 20, and the bracket 15 is moved up and down along the long hole 9 as shown in FIG. After moving and adjusting, the main fastening with the screw 20 was performed. For this reason, not only is the adjustment complicated, but also the assembly time is increased. The bracket 15 and the screw 20 and the support shaft 19 which are moved up and down for adjustment.
