A ring spring 26 is fitted and connected to one end of the ring. Then, when the card C is not inserted, the control lever 40
Although the slider 25 is brought into contact with the expansion force of the ring spring 26 that rotates in one direction (FIG. 2 (b)), when the slider 25 is pushed away from the control lever 40 by being pushed by the head holder 20. As shown in Fig. 83 (b), the control lever 40 is biased by the inverted ring spring 26 in the direction of pressing the lower end of the lock pawl 50, and two solenoids (described later) 5OL1.
Controlled by 5OL2.

The first solenoid 5QLI has a function of releasing the control lever 40 in the lock claw pressing direction immediately before the card C is installed;
It is provided with a function that disables the operation of the manual eject button 70 during retit, and when it receives a detection signal from the first switch SWI that detects the state immediately before installing the car FC, it is temporarily energized and the first switch is activated. While attracting the iron piece 8-61 and removing its locking claw 62 from the locking portion 42 of the control lever 40, the iron piece 8-61 is made movable in the direction in which the locking claw is pressed.
When the computer starts a read/write operation by the second swift switch sw2 that detects the attachment state of the card C,
During this period, the iron piece lever 61 is held under suction by the output signal from the computer, and a part of the lever 61 is operated so as to make it impossible to push the manual eject button 70.

On the other hand, the second solenoid SOL 2 receives a signal from the computer and moves the control lever 40 to the long claw 5.
As shown in Figure 5, this device is equipped with a function to release 0 from the detention position, and as shown in Fig. When any of these signals is received, the second iron piece 8-63 is attracted against the spring 65, and the latch 11-claw 64 is actuated by the control lever. 40 from the locking part 43. Reference numeral 70 denotes the above-mentioned manual ejection button for ejecting the card, and this button 70 is attached by a spring 71 so as to always protrude from the front plate 13 of the casing 10. A rod 72 extending inside the casing 10 is provided on this button 70. , one end of a rod 73 branched from this rod 72 is located opposite to the second lever 63 in the non-suction state so as to be able to press it in the suction direction, and the tip of the other rod 74 is opposite to the second lever 63 in the suction state. 61, and faces the position where the pushing is prevented.

In the figure, reference numeral 18 indicates a roller provided in the insertion path of the card C, and reference numeral 19 indicates a connector.

The operation of the apparatus described above will now be explained.

Before inserting the car FC shown in FIG. 2, the head holder 20 is positioned on the card insertion slot 11 side by the pullback spring 21, and the control lever 40 is moved to the second lever for ejecting the previous card. The locking by 63 is released, and the main body 1
0, that is, in a state in which it has moved to the right in the figure, it receives engagement IF by the first lever 61. Therefore, in this state, the claw 51 of the locking claw 50 is retracted from the insertion path of the card C, as shown in FIG. 4(A).

The slider 25 is brought into contact with the rear end of the control lever 40 by the tension of the ring spring 26 (FIG. 2(b)).

In this state, when the card C is inserted through the insertion slot 11 and the head holder 20 is pushed into the head holder 20 with its tip while resisting the pullback spring 21, the contact head 30 held in the frame-shaped holder 24 is moved. When the card C is pushed near the predetermined mounting position with the inclined surface 16 facing up, the head pin 31 is pulled in against a spring (not shown) and contacts the contacts on the back of the card C with an appropriate contact pressure. (Figure 3 (a)).

On the other hand, when the head holder 20 moves to the right and presses the slider 25 in the process, the slider 25 gradually moves away from the control lever 40 and at a certain stage reverses the ring spring 26 counterclockwise in the figure. For this reason, the lever 40 is now subjected to a suppressing action to the left in the figure by the expansion force 26 of the ring spring, but the control lever 40 is still attached to the locking pawl 62 of the second lever 63 at this point. Since he has been detained, he remains in that state.

In this state, the card C continues to be inserted, and when it reaches a predetermined mounting position, the first switch SWI, which is a combination of a light emitting element and a light receiving element, switches the card C.
Detects the insertion of the first solenoid l with the detection output.
” Momentarily excite SQL, attract and control the first position /<-51, and remove the connection 11- of <-40 (Figure 3 (b)
).

The unlocked control lever 40 is moved by the ring spring 26 (
The force moves to the left in the figure and presses the lower end of the long claw 50, and rotates it in the direction 3" in the figure to restrain the rear end of the installed card C. )) This locked state is maintained by the locking pawl 64 of the second lever 63 that falls into the locking portion 43 as the control lever 40 moves to the left (FIG. 3(b)). .

By the way, when you release your hand after pushing the car FC all the way, the card C will move back a little along with the head holder 20 due to the biasing force of the pullback spring 21 due to the slight gap between the rear end of the card C and the lock claw 50. During the pushing process, the contact head 30 pushed in by the rear wall of the frame-shaped storage part 24 is positioned with a slight gap δ between it and the front wall of the storage part 24, so that the card C is not easily retracted. As a result, the relative movement between the card and the head pin 31 produces a self-cleaning effect, and the two come into reliable contact.

When card C is completely set, the second switch sw2
The computer starts a read/write operation based on the output signal from the computer, but at the same time as this reading, the first solenoid SQL is energized again by a signal indicating that the eject is not allowed from the computer, and the first solenoid SQL is activated so that the manual eject button 70 cannot be pushed. Aspirate 61.

Next, when the reading of the card Cl7) is completed, a read/write completion signal from the computer or an eject signal output from the computer and a signal from the key fob is input to the second renoid 5OL2. Therefore, the second solenoid excited by this signal
"SOL 2 attracts the second lever 63 to release the locking of the control lever 40 and free the lock claw 50. By the way, this long claw 50 has a pull-back mechanism via the head holder 20 and the card C. Since the strong force of the spring 21 is acting, the lock pawl 50 which is released from the engagement [I-] is held by the ring spring 2.
The card C is controlled against the urging force of 6 to move the card 8-4o to the right in the figure and rotate counterclockwise to eject the card C out of the machine.

In addition, if it becomes necessary to take out the card C manually after setting it, use the first solenoid l" S Q.
By pressing the manual eject button 7o before the start of reading when L is in a demagnetized state and after the end of reading, the second lever 63 is rotated to release the lock of the control lever 4° by the tip of the rod 73. can.

FIG. 6 shows another embodiment of the present invention regarding a card lock mechanism, in which a solenoid is connected to the rear end of a long claw 50 provided on both sides 13, 13 of the front plate 12 via an appropriate link mechanism 52. This solenoid SQL is energized by a switch for detecting the card insertion state (not shown) to project the claw 51 at the tip of the locking claw into the insertion path of the card C, while receiving a read/write end signal from the computer or the keyboard. The solenoid SOL is demagnetized by the take-out signal outputted by the operation or the switch operated by the manual take-out button 7o, and the claw 51 at the tip of the lock claw is retracted from the insertion path of the car FC.

(Effects) As described in 1-1 above, according to the present invention, since the IC card insertion slot is provided on the side of the main body, the console surface can be used effectively, and the device can be made smaller accordingly. In addition to making it possible to store the ejecting force by using the insertion force of the card, the card is also locked inside the main body when the card is in contact with the connector member, so the stored force in the ejecting direction can be used. This is not only a scale that can accurately position the card by bringing the card into contact with the locking means, but also a locking action between the card and the locking means to prevent card ejection accidents that can easily occur during reading and writing. Furthermore, the card after reading and writing can be quickly and reliably ejected by the stored force.
