Description

[Detailed explanation of the invention] This invention relates to a mechanism for reliably rerunning a magnetic card.It allows rerunning without pushing it in by hand, and also allows the magnetic card to be easily removed and deposited by just pulling it lightly. It is something.

Conventionally, devices that allow the magnetic card to run again include: (1) one that reciprocates the magnetic card once and then stops with the magnetic card caught in the card feeding roller; When the magnetic card could be moved back and forth, there was a device that stopped the magnetic card in a state where it was almost removed from the card feeding roller.

In the case of (2), the magnetic card can be retraveled reliably, but there is an unavoidable problem that a large force is required to remove the magnetic card because a large frictional resistance occurs between the roller and the card. On the other hand, in case (2), the force required to remove the magnetic card is small, but the disadvantage is that the magnetic card must be pushed so that it engages with the rollers when the magnetic card is to be run again.

In the present invention, after one reciprocating motion, a button is pressed to disengage the magnetic card from the roller and apply force to the card in the direction of the roller to hold the magnetic card in pressure contact with the roller. The above-mentioned drawbacks have been solved by this method, and the present invention will be described in detail below with reference to the accompanying drawings showing embodiments.

As shown in FIGS. 1 and 2, the magnetic card reader re-travel mechanism of the present invention recycles the magnetic card 5 that has been reciprocated once at the end of the magnetic card travel path 4 on the card insertion slot 41 side for card feeding. A magnetic card pushing part 1 that presses against the row 221, a driving part 2 that transfers the magnetic card 5 by rotationally driving the roller 21, and a driving part 2 that reverses the direction when the forward movement of the magnetic card 5 is detected. It is composed of a control section 3.

The magnetic card pushing part 1, which is the main point of the present invention, has a spring 12 and a pressing body 1 on the lower surface of a holder 11 which is provided above the magnetic card running path 4 with a distance of the thickness of one card.
A recess 15 capable of storing 3 is provided, and further within the recess 15,
A shaft 14 is installed parallel to the direction in which five magnetic cards travel, and a spring 12 and a pressing body 13 are fitted onto the shaft 14 in order from the magnetic card insertion slot side.

The pressing body 13 is always urged toward the roller 21 by the spring 12, and when a force against the spring 12 is applied, it slides on the shaft 14 in the direction of the applied force.

The lower surface of this pressing body 13 has an uneven surface.

In the driving unit 2, a rotating shaft 22 of a magnetic card feeding roller 21 provided close to the magnetic card pushing unit 1 is connected to an output shaft of a motor 24 via a power transmission mechanism 23 such as a belt.

The control unit 3 includes a switch 31 for detecting the completion of the forward movement of the magnetic card 5 at the end of the magnetic card running path 4 that is farthest from the magnetic card insertion slot 41, and uses the signal from the switch 31 as an input to A motor control circuit 32 is provided that generates a signal for controlling the rotational direction of the motor 24.

Note that 6 is a magnetic head for recording or reading information on the magnetic card 5, and 42 is a guide provided on one side edge of the magnetic card running path 4.

The operation of the magnetic card reader rerunning mechanism of the present invention having the above structure is as follows.

When you push the magnetic card 5 into the magnetic card insertion slot 41,
The magnetic card 5 passes between the pressing body 13 and the magnetic card running path 4 and is pressed against the roller 21 .

When the button is pressed in this state, a means (not shown) for detecting the card state detects the insertion of the card and sends a detection signal to the motor control circuit 32. When the motor 24 is instructed to rotate in the forward direction, the motor 24 is activated. The roller 21 is rotated in the forward direction to move the magnetic card 5 toward the switch 31.

When the magnetic card 5 comes into contact with the switch 31, the motor control circuit 42 generates a reverse rotation signal, so the motor 24 is reversed, the roller 21 is reversely rotated, and the magnetic card 5 is returned toward the magnetic card insertion slot 41. While the magnetic card is moved back, the magnetic head 6 is operated to read or write information.

Additionally, when the magnetic card 5 moves back, when the end of the magnetic card 5 is moved back to the magnetic card push-in part 1, the pusher 13 springs due to the frictional resistance between the magnetic card 5 and the pusher 13. When the magnetic card 5 is pushed against the elasticity of the magnetic card 12 and further moved back, the magnetic card 5 and the roller 21 are separated and one end of the magnetic card 5 protrudes from the magnetic card insertion slot 41 as shown in FIG. A round trip ends in this state.

When this reciprocation is completed, the drive of the motor 24 is stopped and the roller 21 is also stopped.

Then, the pressing body 13 is pushed against the roller 2 by the elasticity of the spring 12.
1 is energized by the force phrase, and this suppressing body 13 causes the magnetic card 5 to
The card 5 is also slid toward the roller 21 as shown in FIG. 4, and the leading end of the card 5 is held in pressure contact with the roller 21.

Therefore, when reciprocating the magnetic card 5 again, it is sufficient to simply apply a signal to the motor 24 to drive the motor 24 in forward rotation and rotate the roller 21 in the forward direction.
Since there is no need to push or move the , program verification after loading the program can be performed extremely easily.

In addition, when removing the magnetic card 5 after completing the round trip,
The magnetic card 5 is in the state shown in Figure 4 above.
The button is disengaged from the roller 21, but the button is pulled against the bias of the pressing member 13, so that it can be easily pulled out.

The magnetic force and reader retravel mechanism of the present invention as described above allows the operator to set the midwifery magnetic card and then press the button to reciprocate the magnetic card repeatedly by controlling the driving unit. Not only is it possible, but after the reciprocating movement is completed [
This is an excellent device that has practical effects in that the magnetic card is not caught in the roller and can be pulled out with an extremely small force.
