The movable plate 63 is locked by the pin 73. By keeping the push-on state, the card 1 can be taken out from the card mounting portion 4 lightly. Movable plate 63 again
Is pressed, the lock device is in the push-off state, the holding state of the lock plate 72 and the locking pin 73 is released, and the movable plate 63 returns to the original position by the movable biasing force of the spring 80. . The feed roller 8a also returns to the position where the card 1 can be fed by the rotational biasing force of the spring 33, and the gear 44d also returns to the set position where it can mesh with the gear teeth 43.

Next, the operation in one embodiment of the present invention will be described. First, the outline of the operation will be described in order with reference to FIG. When the card 1 is inserted into the card insertion slot 26 from the front end face 1a and is lightly pushed by hand along the card mounting section 4, the first detection section 9 detects that the card 1 has been inserted, and the control circuit 7 controls the motor 6 with the control circuit 7. Operate forward rotation. Ri by this forward rotation, the feed rollers 8a is a first card feeding means sends the card 1 in the arrow A direction. The front end face 1a of the card 1 to be fed comes into contact with the contact portion 20, and the sliding plate 21 is also slid in the direction of arrow A. The second detecting unit 10 detects that the card 1 is not reversely inserted by sliding the sliding plate 21, and the control unit 27 presses the card-side connector 2 until the card-side connector 2 approaches the main-body-side connector 5. The portion 25 is projected to a position close to the rear end face 1c of the card 1. Then, the rotational force of the motor 6 is transmitted to the sliding plate 21 via the transmitting portion 28 as the second card feeding means and is converted into a sliding force for sliding in the direction of arrow A. Therefore, the pressing portion 25 moves the rear end face 1 c of the card 1 forward by the driving force of the motor 6.
Direction . Therefore, the card 1 is strongly pressed and the connectors 2 and 5 are automatically engaged. In this engaged state, the card 1 reaches the end, but the third detector 11 detects this and the control circuit 7 causes the motor 6 to stop rotating.

Next, the case where the card 1 is ejected from the mounting section 4 will be described in order. When the push button 29 for eject operation is pressed, the control circuit 7 causes the motor 6 to rotate in the reverse direction. The sliding plate 21 transmits the torque of the motor 6 to the transmission unit 2.
8 and is forcibly slid in the direction of arrow B. Accordingly, the card 1 is forcibly slid in the direction of the arrow B by the contact portion 20, and the engagement between the connectors 2 and 5 is released. Then, the portion of the front end face 1a is discharged to the position of the feed roller 8a provided on the mounting section 4 for the card 1. Then, the detection unit 9 detects that the card 1 has been ejected, and stops the reverse rotation operation of the motor 6 by the control circuit 7. Then, the card 1 can be easily pulled out manually from the card mounting section 4, and the card insertion slot 26
More can be taken out.

The above is the outline of the operation. The detailed operation in one embodiment of the present invention will be described with reference to FIGS.
The card 1 is inserted through the insertion slot 26 and the feeding rollers 8a, 8
spring 17 as shown in Figure 5 when exposed to b the switch S ₁ of the arm 9a so extremely small as compared with the biasing force of the spring 33 is rotated in a direction downwardly as indicated by arrow E detecting section 9
Is closed.

When the switch S ₁ is closed, the insertion of the card 1 is detected, and the control circuit 7 controls the motor 6 to rotate forward. By this forward operation, the feed rollers 8a,
8b, the card 1 is pinched and sent in the direction of arrow A. The front end face 1 a of the card 1 is attached to the contact portion 20 provided on the release plate 22.
Until the contact is made, the load applied to the feed roller 8a is slight only at the leaf spring portion 4b provided on the card mounting portion 4 for preventing ejection. When the front end surface 1a of the card 1 contacts the contact surface 20 provided on the release plate 22 and the sliding plate 21 is still fed by the feed rollers 8a and 8b against the spring 42, the detecting unit switch S ₂ of 10 detects that the card 1 is closed is not reversed insertion.

The card 1 is fed by the feed rollers 8a and 8b, the sliding plate 21 slides, and the card-side connector 2
As shown in FIG. 7, the control unit 27 is moved until the connector approaches the connector pin 5 a provided on the main body side connector 5.
The guide roller 54 is guided by a cam groove 55 provided in a cam plate 56
Is rotated upward so that the pressing pin 50 projects from the opening 51. The protruding pressing pin 50 approaches the rear end face 1c of the inserted card 1.

When the sliding plate 21 slides continuously, the gear teeth 43 provided on the sector arm 40 connected to the sliding plate 21 and rotated in the counterclockwise direction become the gears 44d of the transmission unit 27 described above. Mesh with. Since the gear 44d is rotated by the rotational force of the motor 6, the sliding plate 21 is forcibly slid in the direction of arrow A this time. The pressing pin 50 has already been
The contact surface 50a contacts the rear end surface 1c of the card 1 and forcibly presses the card 1 so that the connector pin receiving portion of the card side connector 2 and the connector pin 5a of the main body side connector 5 are strong. Engage with force. Connector 2
And the engagement of 5 is achieved, is closed switch S ₃ of the detection unit 11 by the abutment pin 38 provided on the sliding plate 21, the rotation of the motor 6 detects that the card 1 has reached the end Stop the operation.

When the gear teeth 43 of the sector arm 40 rotated by the slide plate 21 engage with the gear 44d by the roller cam 21b formed integrally with the slide plate 21, the rotary arm 31a, The rotating arms 31a and 31b are rotated against the spring 33 and lifted upward by contacting a pair of rollers 36 provided on the 31b. By moving the rotating arms 31a and 31b upward, the roller 8a is separated from the surface of the card 1. Therefore, even if the card 1 is in the engaged state of the connectors 2 and 5, the roller 8a is in a no-load state, so that the roller 8a is not deformed by crimping. The card 1 is electrically connected to the main body 3 by the engagement of the connectors 2 and 5, and data processing is performed.

Next, details when the card 1 is ejected will be described. As described above, when the motor 6 is rotated in reverse by pressing the push button 29 for eject operation, the sector arm 40 is rotated clockwise by the engagement between the gear teeth 43 and the gear 44d, and the sliding plate 21 is forced. Is slid in the direction of arrow B. Due to this sliding, the card 1 is forcibly slid in the direction of arrow B, and the connectors 2 and 5
Is disengaged.

While the card 1 is disengaged from the connectors 2 and 5, the contact of the feed roller 8a with the roller 36 and the roller cam 21b provided on the sliding plate 21 is released, and the card 1 is released. It is pressed again to the surface. The feed roller 8a sandwiches the card 1 between the feed rollers 8b and feeds the card 1 in the direction of arrow B. The front end surface 1a of the card 1 is slightly closer to the card insertion slot 26 than the positions of the feed rollers 8a and 8b. Send to position. And the feed roller 8a is the card 1
The card 1 is released from the surface and the ejection of the card 1 is completed. The end of the card 1 protrudes from the insertion slot 26 to a length sufficient for manual removal.

When the card 1 is incorrectly reversely inserted, the end face of the card 1 abuts against the front end face of the insertion guide 5b provided on the main body side connector 5 for preventing incorrect insertion. Guide 5b
The card 1 can be sent to a position where the card 1 comes into contact with the front end face, but the card 1 cannot be sent any further in the insertion direction. Therefore, the rotation arm 1 of the detection unit 10 for detecting erroneous insertion
Can not be rotated to 0a, it is impossible to close the switch S _2. If the switch S ₂ is not closed in the switch S ₁ of the detection portion 9 of the card insertion detection inserts the card 1 is closed by the set time by detecting the erroneous insertion to discharge the card 1 to reversely rotate the motor 6 .

Although the card 1 is automatically ejected in this manner, it is impossible to remove the card 1 from the mounting section 4 due to a failure of the motor 6, the control circuit 7, a power failure, or the like.
However, in this case, the card 1 can be manually ejected as shown in FIG.

When the distal end of the driver is inserted from the insertion opening 81 and the bent portion 65 is pressed strongly, the movable plate 63 is slid in the direction of arrow C. When the movable plate 63 slides, the arm 68 rotates clockwise, and the arm 45 slightly rotates counterclockwise. Then, the meshing state between the gear teeth 43 provided on the sector arm 40 and the gear 44d is released. Therefore, the sector arm 40 can be returned by the biasing force of the spring 42. The movable plate 63 holds the rotating arm 31b by a cam plate 64 provided on the movable plate 63 so that the feed roller 8a does not press against the surface of the card 1.
Then, the movable plate 63 is a roller 66 provided on the movable plate 63.
Is pressed against the end of the arm 60, and the arm 60 is
Rotate counterclockwise around 3 as a fulcrum.

At this time, since the sliding plate 21 is located at the end of the sliding range in the direction of arrow A, the roller 67 provided on the sliding plate 21 is located at a position close to the other end of the arm 60. . Therefore, when the arm 60 rotates counterclockwise, the sliding plate 21 is forcibly slid in the direction of arrow B to detach the card 1 from the connector 5 on the main body side and to protrude from the card insertion slot 26 into a range where the card 1 can be manually removed. . Since the movable plate 63 is in the push-on state locked by the locking pin 73 and the lock plate 72, the feed roller 8 a is not pressed against the surface of the card 1. Since the feed roller 8a is not pressed,
The card 1 can be taken out lightly by hand.

When the bent portion 65 of the movable plate 63 is pressed again, the push-off state is established, and the lock plate 72 and the locking pin 73 are set.
Is released, and the card 1 can be returned to a normal insertable state.

The above-described embodiment of the present invention has the following effects. (1) The card 1 is simply inserted into the insertion slot 26, the first detector 9 detects this, the card is fed by the roller 8, and the card 1 is automatically mounted on the mounting section 4. (2) to engagement of the connector 2, 5 are electrically reliably performed, but requires strong force, the card 1 at the time of engagement of the connector 2, 5 is set to the driving force of the rotational force of the motor 6 Since the forcible pressing is performed by the pressing portion 25, reliable engagement is automatically performed. (3) The pressing portion 25 presses the rear end face 1c of the card 1, but when the card 1 enters and exits the insertion slot 26, it automatically retreats from the passage, so that it does not hinder the movement of the card 1. (4) If card 1 is incorrectly reversely inserted , the result will be
As a result, the second detection unit 10 detects this and prevents occurrence of an abnormal situation. (5) Although a strong force is required to release the engagement between the connectors 2 and 5, the rotational force of the
1 and slides, and the front end face 1 of the card 1
By strongly pressing a, the engagement is reliably and automatically released. (6) Since all operations of loading and unloading the card 1 are performed by the single motor 6, the structure is simple and small. (7) Forced manual card even in case of power failure
The ejection mechanism allows the connectors 2 and 5 to be manually disengaged and ejected from the mounting portion 4 of the card 1, so that the card 1 does not remain trapped in the mounting portion 4. (8) Since the connectors 2 and 5 are stopped while the rear end face 1c of the card 1 is pressed by the pressing portion 25, the connectors 2 and 5 are not detached by the vibration impact.

In the embodiment of the present invention, the motor 6 which exerts a rotating power is used as a drive source. However, other various motors such as a linear motor which performs a linear motion may be used. Further, in one embodiment of the present invention, the driving force for operating the pressing portion 25 is such that the rotational force of the motor 6 is obtained via the sliding plate 21, but the driving force of the motor 6 or another plunger or the like is directly obtained. It may be obtained from a driving source. Furthermore, in one embodiment of the present invention, the pressing pin 50 of the pressing portion 25 is disposed below the mounting portion 4, but is not limited thereto, and may be disposed above or on the side. Further, in the present invention, it is needless to say that the present invention can be applied to an auto-changer device for automatically inserting and removing new cards 1 sequentially.
