Description

[Detailed explanation of the invention] <Industrial application field> This invention is a method for recording information on a card-shaped recording medium (hereinafter referred to as an "optical card") by irradiating a light beam and reproducing the recorded information. , or an optical card processing device for performing either recording or reproduction.

<Prior Art> As shown in FIG. 12, a conventional optical card processing device has a card holder 8 having a card holder 80 on its upper surface attached to a guide mechanism 81 so as to be reciprocally movable.
This card holder 8 has a structure in which a drive motor 83 that rotates in forward and reverse directions is linked via a belt 82. An optical head 9 is disposed above the card holder 8 for recording information on the optical card and/or reproducing the recorded information, and operates a drive motor 83. By reciprocating the card holder 8 containing the optical card and moving the optical head 9 relative to the track of the optical card, information is recorded and reproduced.

<Problems to be solved by the invention> However, in the case of conventional optical card processing equipment,
Since there is no lock mechanism for temporarily fixing the card holder 8, the card holder 8 moves when the optical card is inserted into or removed from the card holder 8, so that the optical card can be stably inserted and removed. It is difficult to remove and the attachment position is unreliable. Furthermore, since the position of the card holder 8 is uncertain, a process is required to detect the position of the card holder 8 and transport the card holder 8 to the attachment or detachment position, which complicates the system and requires a long time for positioning control. There were some problems, such as:

<Means for Solving the Problems> The optical card processing device of this invention includes a card holder having a card holder that is reciprocatably supported by a guide mechanism, and a card holder disposed opposite to the card holder to hold the card. an optical head for recording and reproducing information on the optical card mounted on the holding unit;
and a locking mechanism for fixing the card holder when a card is inserted and removed,
The lock mechanism is provided with an actuating piece disposed on the card holder and an actuating protrusion that is removable from the actuating piece that protrudes from the optical head.

<Function> When the card is inserted into and removed from the card holder, the operating piece of the lock mechanism and the operating protrusion engage to fix the card holder, so each operation of inserting and removing the card from the card holder is stabilized. This improves reliability, and eliminates the need to detect the position of the card holder and transport it to the attachment and detachment positions.

<Embodiment> FIGS. 1 to 3 show the configuration of an optical card processing apparatus according to an embodiment of this invention.

This optical card processing device has two guide shafts 12 and 1 inside a case 1 having a card insertion slot 11.

Inside the card insertion port 11, there is a detector (not shown) for detecting the inserted optical card, and a detector for detecting the inserted optical card and a card holder 2.
and a card load/eject mechanism 3 for automatically loading or unloading the card into or from the card holding portion 21.

This card loading/ejecting mechanism 3 positions a loading roller 33 disposed on a rotating shaft 32 below the card holder 2, and loads the rotating shaft 32 via a deceleration mechanism 36 consisting of a pulley or a belt. It is configured to be connected to a motor 37. The loading roller 33 is a substantially semicircular cam made of rubber material, and has a flat cam surface 3.
When the loading motor 4 is positioned horizontally above the rotating shaft 32, the loading motor 3 is attached to the lower surface of the card holder 2 in a non-contact manner.
When the loading roller 33 rotates as a result of the operation in step 7, the optical card inserted into the circular cam surface 35 is carried to a fixed position in the card holding section 21. After the card is loaded, the flat cam surface 34 is positioned horizontally above the rotating shaft 32 again and faces the card holder 2, and at this time the loading motor 37 is stopped.

The card holder 2 is provided with a card tilt correction mechanism 4 for aligning the track direction of the optical card with the moving direction of the card holder 2.

The two card guides 41 and 42 are made of bar material 45.
By pivoting the base end of the bar material 45 to the card holder 2 and connecting the elastic spring 44 to the central part, the card guide 41 on the distal side can be attached to the card holder 2 on the proximal side. It is configured so that it is always pushed out toward the card side by the card guide 42. The other card guide 43 is connected to the tip of a leaf spring 46 whose base end is fixed to the card holder 2 .

These card guides 41, 42, and 43 sandwich the optical card 77 from both sides, and
7 is slidably guided at three points on both sides, and the stop guide 4
Determine the mounting position at 0.

An actuating protrusion 47 is provided on the tip side of the bar member 45, and an actuating piece 73 that engages and disengages inside the actuating protrusion 47 is attached to the optical head 7. Therefore, the optical card 77 engages with the card holder 21,
When the optical card 77 is supported at the mounting position by the card guides 41, 42, 43 and the stop guide 40, the angular difference between the track direction and the card feeding direction of the optical card 77 is detected by a sensor (not shown), and the difference is determined according to the detected amount. When the optical head 7 operates, the actuating piece 73 actuates the actuating protrusion 47, and the optical card 7
Correct the slope of 7.

On one side of the operating protrusion 47, there are
As shown in the figure, a stopper piece 48 perpendicular to the direction of movement of the card holder 2 is integrally bent, and the locking mechanism 5 of the card holder 2 is constituted by this actuating protrusion 47 and the actuating piece 73.

10 and 11 show another embodiment of the lock mechanism 5, in which an actuating piece 73 for stopping the movement of the card holder 2 is connected to the lock pin 5 of the solenoid 52.
It consists of 1. Note that the location, number, drive method, etc. of the lock mechanism 5 are not particularly limited.

On the rear side of the card holder 2, there are
As shown in the figure and FIG. 10, a guide shaft 22 that is perpendicular to the direction of movement of the card holder 2 is provided to support a slide member 23, and this slide member 23 is linked to the card feeding mechanism 6.

The card feeding mechanism 6 has two support shafts 60 and 61 supported on a fixed frame 13 in the case 1, pulleys 62 and 63 are respectively fixed to both support shafts 60 and 61, and an endless belt 64 is wound around the card feeding mechanism 6. A connecting pin 65 is vertically installed at a suitable position on this endless belt 64, and this connecting pin 65 is pivotally connected to the slide member 23. A pulley 66 is fixed to the lower part of one of the support shafts 60, and is linked to a drive motor 68 that rotates in one direction via a transmission means 67 such as a belt. An encoder 69 is provided on the other support shaft 61.

The optical head 7 is supported by a lead screw 70 and a guide shaft 71, which are disposed perpendicular to the direction in which the card holder 2 moves, and a head feed motor 72 that can rotate in forward and reverse directions is linked to the lead screw 70. When the head feed motor 72 is operated,
The optical head 7 has a guide shaft 71 and a lead screw 70.
The optical card 77 moves in a direction perpendicular to the feeding direction of the optical card 77 and accesses the track. The operating piece 73 of the lock mechanism 5 is provided protruding from the side of the optical head 7.

However, in the card insertion standby state, the card holder 2 is located near the card insertion slot 11,
The loading roller 33 of the card loading/ejecting mechanism 3 has a flat cam surface 34 positioned horizontally above the rotating shaft 33 and facing the card holder 2.

On the other hand, the actuating piece 73 of the lock mechanism 5 engages with an actuating protrusion 47 protruding from the bar member 45, thereby stopping the movement of the card holder 2. In this state, the optical card 77 is inserted from the card insertion slot 11 (Fig. 7), and when the detector detects this,
The loading motor 37 operates, the loading roller 33 rotates, and the inserted optical card 77
is automatically fed into the card holding section 21 by the circular cam surface 35. At this time, since the card holder 2 is fixed by the lock mechanism 5, the optical card 77 is accurately mounted in a fixed position. The optical card 77 carried into the card holding section 21 is supported by the card guides 41, 42, 43 and the stop guide 40 (FIG. 4).

In this state, the angular difference θ between the track direction of the optical card 77 and the card feeding direction is detected by a sensor or the like, and the optical head 7 is operated according to the angular difference θ, and the actuating piece 73 moves the actuating protrusion 47. push. As a result, the inclination of the optical card 77 is corrected as shown in FIG. 5, and the direction of the track and the direction of card feeding coincide.

In conjunction with this operation, the drive motor 68 of the card feeding mechanism 6 operates to move the endless belt 64,
A connecting pin 65 provided on the endless belt 64 pulls the card holder 2 along the guide shaft 12 via the slide member 23 and moves it back and forth.

When the connecting pin 65 reaches the outer periphery of the pulley 62, the connecting pin 65 slides the slide member 23 in the width direction with respect to the card holder 2, and the pulley 6
2 and move it to the backward movement side. Next, the connecting pin 65 moves the card holder 2 backward along the guide shaft 12 via the slide member 23, as in the forward movement described above. By continuously rotating the drive motor 68 in one direction in this manner, the reciprocating movement of the card holder 2 is realized. When the card holder 2 moves back, the track of the optical card 77 moves relative to the optical head 7, and information recording and reproduction processing is performed. When the card holder 2 returns to the initial position, the head feed motor 72 is operated in conjunction with this, and the optical head 7 is moved along the guide shaft 71 and the lead screw 70, and the track is accessed. The feeding operation is repeated.

Even when the card is removed, the actuating piece 73 of the lock mechanism 5 engages with the actuating protrusion 47 to stop the movement of the card holder 2, thereby realizing stable removal of the optical card 77.
