As shown in (b), the engaging portions 4-cc and 5-aa formed in the cam groove 4-c and the cam groove 5-a respectively engage with the operating pin 2-a to lock the driven plate 4 and the driven plate 4. The rotation position of the urging plate 5 is restricted.

The driven plate 4 is rotatably supported around a support shaft 4-a raised from the traveling guide 1, and the lock urging plate 5 is rotated by a support shaft 4-b provided on the driven plate 4. It is movably supported. The lock urging plate 5 is urged in the counterclockwise direction by the spring 6, and the bent portion 5d formed on the lock urging plate 5 is engaged with the end face of the driven plate 4, so that the driven plate is driven. 4 is also urged in the counterclockwise direction like the lock urging plate 5.

As shown in FIGS. 2 (a) and 2 (b), a cam groove 4-c, a cam groove 5-a and an engaging portion 4-cc formed in the driven plate 4 and the lock urging plate 5, respectively. 5-aa has the same structure, but the operating pin 2-a is provided with the cam groove 4-c and the cam groove 5-a so that the lock lever 8 is at the card lock position.
At the position B on the left side of the inside, the lock urging plate 5 is rotated clockwise by the rotation of the operation pin 2-a with respect to the clockwise rotation of the operation pin 2-a. 5-bb is formed, on the other hand, the driven plate 4 is not provided with an engaging portion with respect to the clockwise rotation of the operating pin 2-a. It is not rotated by 2-a. Therefore, when the plunger 3-1 is actuated and sucked when the lock lever 8 is in the card lock position which is the second position where it projects into the card passage, the actuation provided in the actuation arm 2 is performed. Depending on the position of the pin 2-a, the driven plate 4 and the lock urging plate 5 perform two different operations.

1 and 2, a pin 5-b is fitted and fixed in the opening 5b of the lock urging plate 5, and the lock urging plate 5 is urged counterclockwise in the opening 5e. One end of the spring 6 for urging is erected, and the support shaft 4-b of the driven plate 4, which serves as the center of rotation, is fitted into the opening hole 5c and tries to rotate in the counterclockwise direction. A bending portion 5d is bent and formed on the bias plate 5, and the turning position of the lock biasing plate 5 is regulated by engaging the bending portion 5d with the engaging portion 4e of the driven plate 4. ing.

In the state before insertion of the card in FIG. 1, the slide plate 7 supported so as to be slidable along the card running path 20 protrudes through the long hole 4-f formed in the driven plate 4. The pin 5-b of the lock urging plate 5 and the engaging portion 7-a formed on the slide plate 7 face each other so as to be engageable in a separated state. The slide plate 7 has a cam portion 7-b for moving the card lock lever 8 up and down, and a spring 77.
Is urged toward the left side, that is, the lock lever 8 to the first position retracted from the card passage, and when the slide plate 7 moves to the right from the state of FIG. The cam portion 7-b formed by the long hole on the side surface
The engaging member 8-a of the lock lever 8 inserted into the cam portion 7-b is moved to lift the protruding lock portion 8-b at the tip of the lock lever 8 to lock the card. .

Next, the operation of the card lock and the unlocking mechanism in the above embodiment will be described with reference to FIGS. The state of FIG. 3 is a plan view showing a card insertion waiting state before the card is inserted.

In the card reader of this embodiment, the card reader is
The magnetic head, which reads / writes data with the card as the card is inserted, is placed in the direction opposite to the running direction of the card.
Since it is a card reader that moves along the magnetic stripe on the card, the head carriage 9 to which the magnetic head is attached is located on the left side of the card running path in FIG. The shoulder 9-a of the carriage 9 and the protrusion 4-d formed on the driven plate 4 are in contact with each other. Therefore, the driven plate 4 locks the counterclockwise rotation by both the shoulder portion 9-a of the head carriage 9 and the operating pin 2-a of the operating arm 2, and the lock urging plate 5 is locked. The cam groove 5-a is also at the position A, and the counterclockwise rotation by the spring 6 is also locked, and the pin 5-b of the lock biasing plate 5 and the engaging portion of the slide plate 7 are engaged. The engagement with 7-a is also prevented. Therefore, the cam portion 7-b formed at the right end of the slide plate 7 in the figure makes the engagement member 8-a of the lock lever 8 retracted from the card passage,
The protruding portion 8-b of the lock lever 8 is in the first position retracted from the card passage.

In FIG. 3, when a card is inserted from the right side, the head carriage 9 moves in the card insertion direction side in parallel with the card traveling path by a mechanism (not shown). Therefore, the protruding piece 4-d of the driven plate 4 is released from the engagement of the shoulder portion 9-a of the head carriage 9, but the driven plate 4 and the lock urging plate 5 are the operation pins 2- of the operation arm 2.
Since the state in which the counterclockwise rotation is locked by a continues, the head carriage 9 does not rotate only by moving.

When the insertion of the card to the predetermined position is completed, the solenoid 3 is driven for a short time by the output of a sensor (not shown) which detects the insertion of the card. When the plunger 3-1 is attracted by the driving of the solenoid 3, the actuating arm 2 connected to the plunger 3-1 rotates clockwise around the support shaft 2-1 to actuate the actuating arm. The operation pin 2-a provided at the other end of 2 is moved upward. Therefore, the operating pin 2-a is engaged with the engaging portions 4-cc and 5- formed in the cam grooves 4-c and 5-a of the driven plate 4 and the lock urging plate 5.
The driven plate 4 and the lock urging plate 5 are allowed to rotate in the counterclockwise direction out of the engaged state with the aa.
Since the bent portion 5d engages with the engaging portion 4e of the driven plate 4, both of them rotate integrally in the counterclockwise direction. When the solenoid 3 is shortly driven and turned off, the actuating pin 2-a of the actuating arm 2 engages the cam groove 4-.

In the process of moving the lock biasing plate 5 to the lock biasing plate 5 by the biasing force of the bar 6,
Since the engaging portion 4e of the driven plate 4 is engaged with the driven plate 4,
Also rotates counterclockwise. When the driven plate 4 and the lock urging plate 5 rotate counterclockwise, the pin 5-b of the lock urging plate 5 is rotated.
Contacts the engaging portion 7-a of the slide plate 7 and pushes it to the right, and the slide plate 7 slides in the right direction in the figure. By this sliding to the right, the engagement member 8-a of the lock lever 8 is caused by the cam portion 7-b provided on the slide plate 7.
Rotates counterclockwise about the rotation support shaft 8-c,
As a result, as shown in FIG. 4, the protruding portion 8-b at the tip of the lock lever 8 is lifted to the second position where the card is locked.

When the recording or reproducing on the card is completed, FIG.
The solenoid 3 is again excited for a short time, as shown in FIG. 5, and the plunger 3-1 is again attracted. Before the solenoid 3 is again excited for a short time, the operating pin 2 of the operating arm 2
a is located at the second position B of the cam groove 4-c and the cam groove 5-a, and this excitation causes the operating pin 2-a to move to the cam groove 4-c,
It moves from the second position B of the cam groove 5-a to the upper side in the figure.

Here, the cam groove 4-c and the cam groove 5-a are
As described above, the shape is different, and the cam groove 5-a engages with the operating pin 2-a of the operating arm 2 and the engaging portion 5-.
Since bb is formed, only the lock urging plate 5 is the support shaft 4
Rotate clockwise around -b against the biasing force of the spring 6. When the lock urging plate 5 rotates clockwise, the pin 5-
While b is separated from the engaging portion 7-a of the slide plate 7, this time, on the contrary, the engaging portion 7-c is pressed to move the slide plate 7 leftward. When the slide plate 7 moves to the left, the lock lever 8 rotates clockwise around the support shaft 8-c as the cam portion 7-b formed on the slide plate 7 moves, and the protruding portion 8 is moved.
-B moves downward.

As described above, since the rotation of the lock lever 8 is performed by using the excitation of the solenoid 3, the lock lever 8 is rotated.
Even if the projection 8b of the lock lever 8 is caught by the card, the projection 8b of the lock lever 8 can be reliably brought to the first position retracted from the card passage.

When the driving operation of the solenoid 3 is completed from the excitation state of FIG. 5, the lock lever 8 is moved as shown in FIG.
Is retracted to the first position where the card lock is released,
Cards can be ejected. When the card is ejected in this state, the head carriage 9 correspondingly moves to the left in the figure, and the shoulder portion 9-a of the head carriage 9 pushes the protruding piece 4-d of the driven plate 4 to follow it. Lock plate 5 Lock plate 5
At the same time, it is forcibly rotated in the clockwise direction, and the card lock mechanism returns to the card insertion standby state shown in FIG.

In order to forcibly discharge the card when the solenoid 3 cannot be driven due to a power failure or the like, a perforated portion 11 is provided in the front frame of the card reader and the perforated portion is provided. The rod member may be inserted into the portion 11 and the slide plate 7 may be forcibly pushed back to retract the protruding portion 8-b of the lock lever 8 from the card passage.

7A shows a state in which the contact block 12 is retracted from the card traveling path 20, and FIG. 7B shows a state in which the contact block 12 descends into the card traveling path 20 and comes into pressure contact with the card.

An arm 13 that supports the contact block 12 is rotatably supported by a lower shaft guide forming a card passage by a support shaft 13-a. One end of the arm 13 is connected to the contact block 12 and the other end is connected to the other end. Since the roller 14 is attached and the contact block 12 is biased to the right by the spring 12 ', the roller 14 is in the position engaged with the stepped engaging portion 7-d of the slide plate 7, The block 12 is in a raised position retracted from the card traveling path 20.

The roller 14 engages with the stepped engaging portion 7-d of the slide plate 7 against the biasing member 17 mounted on the actuating arm 2 and the biasing member 18 mounted on the slide plate 7 at one end thereof. When mated, the contact block 12 is retracted from the card running path 20, and the cam portion 7-b provided on the side surface of the slide plate 7 and the engaging member 8-a of the lock lever 8 are loosely fitted at the tip to lock. The protruding portion 8-b at the tip of the lever 8 is lowered to the first position.

When the card 15 reaches and presses the inner surface 13-b of the bent portion of the arm 13, the arm 13 is supported by the support shaft 13-.
