Reference numeral 39 denotes the above-described reverse rotation prevention circuit, which is connected to a multivibrator 39a in which a reverse rotation signal is input to the set terminal S and a signal from the first card detector 20 is input to the reset terminal R via the inverter 34, and the output side thereof. Inverter 3
9b, and is configured to turn off the AND gate 32 when the reverse rotation signal is output.

In this embodiment, the IC card A with the contacts facing downward
When (Fig. 6 (a)) is inserted from the card insertion slot 3 to a position where it abuts on the first feed roller 6, the first card detector 20 detects that a card has been inserted and outputs an H level signal to drive the motor. 5 is rotated in the forward direction, that is, the direction in which the card is pulled inward. The rotation of the motor 5 is transmitted to the first feed roller 6 via the belt 4 and to the second feed roller 18 via the pinion 17 and the mild roller 19. The card is bitten by the first feed roller 6 and drawn inward at a constant speed, and its tip faces the third card detector 22. When the card is further pulled in this way, the rear end of the card passes the first card detector 20, but since the OR gate 30 receives the H level signal from the third card detector 22, the motor 5 continues to operate. The card is rotated forward and the card is fed to the second feed roller 18. The tip of the card is the engaging portion 13 of the contact head carriage 9.
When the contact head / carriage 9 comes into contact with the pinion 17, the contact head / carriage 9 is pushed forward by the moving card and moves slightly forward, and the tip of the rack portion 12a rides on the pinion 17 to move to the pinion 1.
When the pinion 17 is engaged with the pinion 17 and the pinion 17 is rotated, the card is moved to the rear side with the leading end of the card brought into contact with the locking portion 13. In the process of this movement, the carriage 9 is attached to the rack portion 1
Since 2a is engaged with the pinion 17 to move by receiving power, the contact head 16 is moved by receiving reliable power transmission without causing slippage or the like. The contact head 16 gradually rises along the slope 2a. When the contact head carriage 9 moves to a specified position (Fig. 5A), the contact head 16 is fully raised to completely contact the contact pins 16a, 16a, ... with the contacts C, C, C, ... of the IC card A. Let the 4th at the same time
The card detector 23 outputs an H level signal to stop the rotation of the motor 5.

When the writing and reading of data to and from the IC card are completed and a card release signal is output from the host device H, the AND gate 36 outputs an H level signal and the multivibrator 3 is output.
7 is started to rotate the motor 5 in the reverse direction, that is, the card ejection direction. The IC card is the second feed roller 1
The carriage 9 is moved in the direction of the card insertion slot 3 by 8, and at the same time, the carriage 9 is moved toward the home position by following the card by receiving the biasing force of the spring 11 and the driving force from the pinion 17. At this time, since the tip of the card is separated from the fourth card detector 23, the AND gate 31 inputs the H level signal from the third card detector 22 and the inverter 35 and outputs the H level signal. Since the L level signal from the reverse rotation prevention circuit 39 is input to the other terminal of 32, there is no possibility of rotating the motor 5 in the forward direction.

In this way, when the trailing edge of the card passes the third card detector 22, the leading edge of the IC card moves to the first feed roller 6
Further, the carriage 9 is pulled back to the home position by the spring 11 and disengaged from the pinion 17. When the card moves further and the rear end passes the second card detector 21, the second card detector 21
It detects that one end of the medium has protruded from the card insertion slot, outputs an L level signal, resets the multivibrator 37, and stops the rotation of the motor 5. This allows
As shown in FIG. 5B, one end of the card is projected from the card insertion slot 3 and the other end is stopped while being sandwiched between the first feed roller 6 and the idle roller 24. At this point, when the portion protruding from the card insertion slot 3 is pinched by hand and pulled out, the engagement with the first feed roller 6 is released and the card can be taken out.

On the other hand, in the case of the magnetic card B (FIG. 6B), when the magnetic stripe D is inserted into the card insertion slot 3 in the direction facing the magnetic head, the first card detector 20 detects the insertion of the card. Rotate the motor 5 to pull in the card,
The card moves inward at a constant speed while the magnetic stripe D is being pressed against the magnetic head 7. In this way, the reading of the magnetic stripe is completed before the tip of the magnetic card comes into contact with the locking portion 13 of the contact head carriage 9.

As a result, accurate reading and writing of data by the magnetic head 7 is guaranteed without reducing the moving speed of the magnetic card. The magnetic stripe surface of the magnetic card is the magnetic head 7.
When the reading and writing of the data is completed by passing through, the multivibrator 37 receives the H level signal from the third card detector 22 and the card release signal from the host device H, and reverses the motor 5. The card is the second feed roller 1
It is sent back to the first feed roller 6 by 8 and is then transported by the first feed roller 6 toward the card insertion slot 3. In this way, when the trailing edge of the magnetic card passes the second card detector 21, the second card detector 21 moves to L
A level signal is output to reset the multivibrator 37 and stop the rotation of the motor 5. As a result, the magnetic card is stopped with one end protruding from the card slot 3 and the other end sandwiched between the idle roller 24 and the first feed roller 6 (FIG. 5B). At this point, the card slot 3
If you pull out the part that is protruding from the
The card can be taken out after the engagement with the feeding roller 6 is released.

In this embodiment, the card transfer means is composed of a plurality of rollers 6 and 18, but a belt having a length from the card opening to the contact head contact position may be driven by a motor. Play an action.
