1 is a perspective view of an IC memory card and an IC card attaching / detaching device 1 according to an embodiment of the present invention.

The IC memory card and the IC card attaching / detaching device 1 are actually IC cards having a built-in CPU used in ID cards, credit cards, etc. This is incorporated as a part of the internal structure of a data writing / reading device (not shown; hereinafter simply referred to as a “card device”) of a corresponding card (hereinafter simply referred to as “card”). Of the internal configuration of the card device, only the configuration related to the IC memory card and the IC card attaching / detaching device 1 is extracted and shown. The other configuration of the card device (not shown) is the same as that of the conventional card device except that a configuration for giving a command signal to a lock mechanism 8 of the IC memory card and IC card attaching / detaching device 1 described later is added. It is the same.

In FIG. 1, the IC memory card and IC card attaching / detaching device 1 is generally composed of a guide frame 2 on which a card 10 is attached, a card holder 9, an eject mechanism 5 including an eject lever 3 and an operation bar 4, and a lock lever 6. And a lock mechanism 8 including an electromagnetic solenoid 7 corresponding to the drive mechanism.

In the present embodiment, the guide frame 2, the card holder 9, the eject lever 3, the operation bar 4 and the lock lever 6 are integrally formed sheet metal products.

The guide frame 2 is a card 10 on the bottom plate 2c.
Rails 2a and 2b for holding the card 10 are formed on both left and right sides with respect to the insertion direction of the card, and gate-shaped frames 2d and 2e are formed on the upper portions of the rails 2a and 2b for preventing lateral displacement of the card 10. Has been done, this frame 2
The central portions of d and 2e are connected by a bridging bar 2f. A connector 2g to which the input / output terminal 10a of the card 10 is connected is fixed to the surface of the bottom plate 2c. Further, a pivot 3a for supporting an eject lever 3 described later is provided behind the connector 2g. The guide frame 2 is fixed to the card device.

Further, the connector 2g is provided with an external terminal (not shown) (68 pins in this embodiment). These external terminals are provided at the lower part of the connector 2g and penetrate through through holes provided in the corresponding part of the bottom plate 2c to be connected to the internal circuit of the card device, or they are provided at the rear part of the connector 2g and project backward once. After that, it is bent downward and connected to the internal circuit of the card device. By this connection, the card 10 is connected to the internal circuit of the card device via the connector 2g.

Next, the eject lever 3 of the eject mechanism 5 is pivotally supported on the card device by a pivot 3a so as to be horizontally rotatable in the directions A and B. Further, when the card 10 is mounted on the guide frame 2 at one end of the eject lever 3, a pressing plate 9c of a card holder 9 which will be described later is moved along with the insertion of the card 10 in the card insertion direction.
The contact piece 3b is provided at a position where the contact piece 3b contacts. Further, at the other end of the eject lever 3, there is provided a pressing plate 3c with which one end of an operation bar 4 described later abuts.

The card holder 9 is held movably with respect to the guide frame 2 in the insertion and ejection directions of the card 10, that is, in the directions J and K in the figure. This card holder 9
Includes a bottom plate 9e that slides on the bottom plate 2c of the guide frame 2 together with the tip of the card 10 and an upper plate 9f.
The left and right ends of the tip of 0 are connected by side plates 9a and 9b with which they abut. When the card 10 is inserted, the front end of the card 10 is attached to the upper plate 9f and the bottom plate 9f.
It is a structure inserted between e and e. This side plate 9a, 9b
A notch 9d into which the above-mentioned connector 2g is fitted is provided between them. Further, a pressing plate 9c is provided so as to project upward in the central portion of a portion of the upper plate 9f adjacent to the cutout portion 9d. Furthermore, the portion of the bottom plate 9e that comes into contact when the card 10 is inserted passes through the bottom plate 9e without being locked when the card 10 is inserted.
It has an edge shape so as to come into contact with the side plates 9a and 9b after sliding along the e-shape.

The operation bar 4 has a support mechanism (not shown),
The card device is supported so as to be horizontally reciprocally movable in the directions C and D. In addition, a spring 4 is provided on the side surface of the operation bar 4.
One end of a is fixed, and the other end of the spring 4a is fixed to the card device, so that the operation bar 4 is always subjected to a pulling force in the direction of C by the spring 4a. A push button 4b is attached to the other end of the operation bar 4, and the end of the push button 4b opposite to the side attached to the operation bar 4 is exposed to the outside of the card device. It is possible to operate from.

Further, the operation bar 4 has lock slits corresponding to the two lock receiving portions with which a lock plate 6b of a lock lever 6 described later is engaged, in the order of 4c and 4d from one end side to the other end side of the operation bar 4. Has been formed.

Next, the lock lever 6 of the lock mechanism 8 is pivotally supported on the card device by a pivot 6a so as to be horizontally rotatable in the E and F directions. A lock plate 6b that engages with the lock slits 4c and 4d of the operation bar 4 is formed at one end of the lock lever 6. Further, one end of a spring 6c is fixed to the other end of the lock lever 6, and the other end of the spring 6c is fixed to the card device. Therefore, the lock lever 6 is always subjected to a pulling force in the H direction by the spring 6c.

Further, the other end of the lock lever 6 and the tip of the push rod 7a of the electromagnetic solenoid 7 are horizontally rotatably connected by a shaft 7b. Also, the electromagnetic solenoid 7
In the exciting circuit 7c, the switch 7d and the power supply 7e are described later by a series circuit.

The electromagnetic solenoid 7 drives the push rod 7a in the G direction when a voltage is applied by the exciting circuit 7c.

Also, due to the internal structure of the card device (not shown), the switch 7d is closed while the data writing and data reading operations of the card 10 are being executed or when the power switch of the card device is off. It is open except for.

Next, the IC memory card and the IC having the above structure
The operation of the card attaching / detaching device 1 will be described.

First, when the power switch of the card device is on, the card 10 is inserted through the card insertion slit (not shown) of the card device. At this time, since the power switch is on and data writing and data reading operations are not performed on the card 10, the switch 7d is opened as described above.

Therefore, since the electromagnetic solenoid 7 is not excited and the push rod 7a is not receiving the driving force of the electromagnetic solenoid 7, the lock lever 6 is moved in the direction H by the pulling force of the spring 6c. The lock plate 6b at one end is pulled and is in the position rotated in the direction F, that is, it is not engaged with the lock slits 4c and 4d of the operation bar 4, so that the operation bar 4 is restrained by the lock plate 6b. No, that is, the lock is released.

The operation bar 4 is pulled in the direction C by the above-mentioned action of the spring 4a and presses the pressing plate 3c of the eject lever 3. As a result, the eject lever 3
Is rotated in the direction B, the contact piece 3b is pushed forward, and thus the card holder 9 is also pushed forward.

When the card 10 is inserted into the card insertion slit of the card device in this state, the card 10 is inserted into the guide frame 2 while being pushed in the J direction. Further, the tip of the card 10 is inserted into the card holder 9 so that the side plate 9
By contacting and pressing the a and 9b, the card holder 9 is pressed in the insertion direction J of the card 10. Therefore, the contact plate 3b is pressed by the pressing plate 9c of the card holder 9, and the eject lever 3 is rotated in the direction A. Therefore, the pressing plate 3
c is pushed forward and pushes the operation bar 4 in the direction D. By the movement of the operation bar 4 in the D direction, the card 10 is locked by a slide locking mechanism (not shown). Also, the input / output terminal 1 provided at the tip of the card 10
0a is fitted and connected to the connector 2g on the bottom plate 2c of the guide frame 2 via the notch 9d of the card holder 9. This completes the mounting of the card 10. It should be noted that when the operation bar 4 is in the direction of D, the one of the lock slits 4c of the operation bar 4 faces the lock plate 6b of the lock lever 6.

In this state, data writing and data reading operations for the card 10 are performed. Therefore, as described above, the switch 7d is closed and the electromagnetic solenoid 7
Is excited and the push rod 7a is driven in the G direction. Therefore, the lock lever 6 is rotated in the direction E, and the lock plate 6b engages with the lock slit 4c of the operation bar 4 which faces the lock bar 6b as described above, and the operation bar 4 is deviated in the direction D by the lock plate 6b. Is locked and locked.

Therefore, even if the card 10 is ejected by accidentally pressing the push button 4b from the outside during execution of the data writing and data reading operations, the push button 4b can be pushed due to the locked state. No discharge operation is possible. Therefore, erroneous operation is prevented.

Next, when the data writing and data reading operations are completed, the switch 7d is opened as described above. Therefore, the excitation of the electromagnetic solenoid 7 is released, the push rod 7a stops receiving the driving force, the lock lever 6 is rotated in the F direction by the action of the spring 6c, and the lock plate 6b is locked by the lock slit 4 of the operation bar 4.
It is removed from c, and the locked state is released.

When the card 10 is pulled out in this state, since the locked state of the operation bar 4 is released as described above, the push button 4b can be pushed, and the push button 4 can be pushed.
By pushing b in the direction C, the operation bar 4 is moved in the direction C, and the movement of the operation bar 4 unlocks the card 10 by the above-mentioned slide-shaped mechanism (not shown). Further, the pressing plate 3 is moved by moving the operation bar 4 in the C direction.
c is pressed, so that the eject lever 3 moves to the card 10.
It is rotated in the direction B opposite to the direction when it is attached, so that the contact piece 3b is pushed forward. As a result, the pressing plate 9c of the card holder 9 is pressed, so that the side plates 9a, 9b
Is pushed out in the ejecting direction of the card 10, so that the card 10 is pushed out in the K direction by the side plates 9a and 9b of the card holder 9, and at the same time, the input / output terminal 10a of the card 10 is pushed.
Is separated from the connector 2g, and the card 10 is ejected from the card insertion slit of the card device.

At this time, the operation bar 4 has the push button 4
Even after b is released from the pressed state, the state in which it is still moved in the C direction is maintained by the above-mentioned pulling force of the spring 4a. In this state, the lock slit 4d on the other end side of the operation bar 4 faces the lock plate 6b of the lock lever 6.

When the power switch of the card device is turned off with the card 10 ejected, for example, when the card device is to be maintained, the switch 7d is closed and the electromagnetic solenoid is operated. 7, the operation bar 4 is locked by the lock plate 6b engaging with the lock slit 4d facing the lock plate 6b as described above in a state where the card 10 is ejected, that is, in the state in which the operation bar 4 is closer to the C direction. It In this state, the operation bar 4 is in the D direction, that is, the eject lever 3 is rotated in the B direction and the contact piece 3b is pushed forward.

Therefore, in this state, even if an attempt is made to insert the card into the card insertion slit of the card device, the contact piece 3b is pushed forward and the card holder 9 is pushed forward. The card comes into contact with the side plates 9a and 9b of the card holder 9, and the card can be inserted only part way. Therefore, the operator can recognize that the card device is not in the operating state. Further, for example, it is possible to prevent the trouble that the maintenance work is hindered by the insertion of the card during the maintenance of the card device.

Further, when all the power supplies are cut off due to, for example, a power failure during operation, the power supply 7e of the electromagnetic solenoid 7 is also cut off, so that the electromagnetic solenoid 7 is not excited and therefore the operation bar 4 is unlocked. Then, the card can be ejected by pressing the push button 4b in the same manner as when the data writing and data reading operations are completed.

In the present embodiment, the drive mechanism of the lock lever 6 of the lock mechanism 8 is constituted by the electromagnetic solenoid 7, but it is not limited to the electromagnetic solenoid and may be constituted by a combination of a motor and a cam, for example.

Further, in the case of the present embodiment, the lock grooves 4c and 4d corresponding to the lock receiving portion are provided in the operation bar 4,
The lock grooves 4c and 4d may be provided on the eject lever 3, or the lock grooves may be provided on both the operation bar 4 and the eject lever 3.

Further, the structure corresponding to the lock receiving portion is
It is needless to say that the structure is not limited to the lock groove of the present embodiment, and may be formed by forming a protrusion, for example.

Further, in the present embodiment, the operation of the operation bar 4, that is, the discharging operation, is a direct operation by the push button 4b, but in addition, it is once converted into an electric signal by a push button switch, etc. The operation bar 4 may be driven again by exciting the electromagnetic solenoid. Even in that case, as in the case of the direct ejection operation by the push button 4b, when the lock mechanism 8 is in the locked state, the operation bar 4 is constrained so that the electromagnetic solenoid via the electric circuit is operated as described above. Needless to say, the operation of the operation bar 4, that is, the discharge operation cannot be performed even by excitation or the like.

[0040]

As described above, according to the present invention, during the data writing and data reading operations on the card,
The function of the loading lock mechanism prevents the card from being ejected, so that the card is mistakenly ejected during the data writing and data reading operations to the card, for example, the configuration of the data file written in the card is incomplete. Therefore, it is possible to prevent the occurrence of problems such as being unable to read the data file after that. Moreover, this loading
