An eject mechanism 3 is provided.

The card loading/ejecting mechanism 3 is constructed by disposing a loading cam 33 on a shaft below the card holder 2, and connecting this rotating shaft 32 to a loading motor 37 via a deceleration mechanism 36 consisting of a pulley and a belt. . The loading cam 33 is a substantially semicircular cam made of a rubber material, and is mounted so that when the flat cam surface 34 is positioned horizontally above the rotating shaft 32, it approaches the bottom surface of the card holder 2 without contacting it. When the loading cam 33 rotates due to the operation of the loading motor 37, the spherical cam surface 35 carries the corresponding optical card 7 to the fixed position of the card holding section 22, and the flat cam surface 34 faces the holder 2 again. The motor 37 then stops.

The card holder 2 is provided with a card tilt correction mechanism 4 that makes the track direction of the optical card 7 coincide with the moving direction of the card holder 2.

The correction mechanism 4 is provided with roller-shaped card guides 41, 42 and 43 at two locations on one example of the card holding section 22 and one location located in the middle on the other side, respectively.
The card guides 41 and 42 are rotatably supported on both ends of the bar material 45, have their proximal ends pivoted to the holder 2, and have elastic springs 44 connected to their distal ends. 42 so that it is always pushed toward the card side.

An actuating protrusion 47 is provided on the tip side of the bar member 45, and an actuating piece 63 that engages and disengages inside the actuating protrusion 47 is attached to the optical head 6. Therefore, the optical card 7 engages with the card holder 22, and the optical card 7 engages with the card guide 41, 42, 43.
In the point supported state, the track 711 of the optical card
The angular difference between the direction and the card feeding direction is detected by a sensor or the like (not shown), and the actuating piece 63 actuates the protruding piece 47 by the operation of the optical head 6 according to the detected amount, thereby correcting the inclination of the optical card 7. Do what you want.

A guide shaft 23 that is perpendicular to the direction of movement of the holder 2 is provided on the rear side of the card holder 2 to support a slide member 24, and the slide member 24 is linked to the card feeding mechanism 5.

The card feeding mechanism 5 has two support shafts 51 supported on a fixed frame 50 in the case 1, a boot U52. A connecting pin 55 is installed vertically at a suitable position on the belt 54, and this pin 55 is supported and connected to the slide member 24. A boot IJ 56 is fixed to the lower part of one of the support shafts, and a transmission means such as a belt is connected to the belt 54. Drive motor 5 for one-way rotation via 57

The optical card 6 is disposed in a direction orthogonal to the direction in which the card holder 2 moves, and is supported by a lead screw 60 and a guide shaft 61, and a head feed motor 62 that rotates in forward and reverse directions is attached to the lead screw 60.
By the operation of the motor 62, the optical head 6 is moved in a direction perpendicular to the feeding direction of the optical card 7 by means of the guide shaft 61 and the lead screw 60, and performs a tail and tail access operation.

Next, the operation of the optical card processing device of the present invention will be explained.

In the card insertion standby state, the card holder 2 is inserted into the insertion slot 11.
The loading cam 33 of the card loading/ejecting mechanism 3 has a flat cam surface 34 facing the card holder 2 . In this state, the insertion port 11
When the optical card 7 is inserted (Fig. 2) and the detector 31 detects this, the loading motor 37 is activated.
As the spherical cam surface 35 rotates, the inserted optical card 7 is automatically taken into the card holder 22.

The optical card 7 carried into the card holding section 22 is supported at three points by card guides 41, 42, and 43 (FIG. 6). In this state, the sensor detects the angular difference θ between the direction of the track 711 of the optical card 7 and the card feeding direction, and the optical head 6 operates according to the angular difference θ.
7 is pressed to correct the inclination of the optical card 7 as shown in FIG. 7, so that the direction of the trunk 711 and the card feeding direction match.

The card feeding mechanism 5 operates in conjunction with this operation. When the endless belt 54 moves due to the operation of the drive motor 58, the connecting pin 55 provided on the belt 54 connects with the slide member 24.

As in the case of movement, slide member 2
4, the holder 2 is moved back and forth along the guide shaft 13, and the reciprocating movement of the card holder 2 is realized by continuous rotation in one direction of the drive motor 58. When the card holder 2 moves backward, the track 711 of the optical card 7 moves relative to the corresponding optical head 6, and information recording and reproduction processing is performed. When the card holder 2 returns to the initial position, the head feed motor 62 is operated in conjunction with this, and the guide shaft 61 and lead screw 60 perform a track access operation, and the same card feed operation is repeated again.

<Effects of the Invention> The present invention is as described above (because a card holding member is provided on the lower surface of the card holder supported by the guide mechanism, and a card feeding mechanism and an optical head are arranged on the same surface on the lower side). Compared to the conventional type, which has an optical head on the upper side of the card holder and a card feeding mechanism on the lower side, the device can be made thinner and more compact.The card feeding mechanism also has a pair of booleans.
An endless belt is wound between the belts, connecting pins are provided at appropriate places on the belt, and a drive motor that continuously rotates in one direction is connected.On the other hand, the card holder is equipped with a slider that moves the holder in the orthogonal direction. Since the connecting pin is supported and connected to this slider, the slider slides at both pulley positions, and the card holder reciprocates with the continuous rotation of the drive motor, thereby reducing the size of the drive motor. Achieve high-speed operation.

Furthermore, since a card loading/ejecting mechanism is provided, the operation of loading or unloading the optical card into or out of the holding section becomes accurate. Moreover, since the card holder is equipped with a card tilt angle correction mechanism, the tilt angle of the optical card can be corrected according to the angle difference between the trunk line of the optical card and the card feeding direction, allowing the optical head to move within the range required for tracking servo. It has practical effects that achieve the purpose of the invention, such as making the optical head narrower and making the optical head smaller and lighter.
