Description

[Detailed Description of the Invention] The present invention relates to a holding drive device for an optical or magnetic scanning head that scans a recording medium in order to read or write information recorded on the recording medium. This invention relates to a holding drive for a manual scanning head without a power source.

Taking a magnetic head reading and writing device as an example, conventional manual type devices are either a slit type (FIG. 1) or a plug-in type (FIG. 2). In other words, the slit type has a reading/writing device 1 as shown in FIG.
A slit 11 is provided along the slit 11 through which the card 2 can pass, and a magnetic head 12 is built in along the slit 11. When the card 2 is manually passed through, the magnetic stripe 21 of the card 2 is inserted into the magnetic head 12.
It scans, reads, and writes. In this case, when you hold card 2 in your hand and scan it, card 2
Depending on the groove width of the slit 11, the card may be tilted with respect to the magnetic head 12, and may also be tilted with respect to the longitudinal direction of the card 2, which may prevent stable output from the magnetic head 12 and cause errors. was. Furthermore, in order to prevent the card 2 from tilting in the longitudinal direction, it is necessary to increase the length of the slit 11, which has the disadvantage of being large when incorporated into an apparatus.

In the plug-in type, as shown in FIG.
The card is inserted into the insertion hole 31 of the reading/writing device 3 and the magnetic stripe 21 is scanned by the built-in magnetic head 32 to perform reading or writing.However, since the card 2 is held by a human hand, There was a drawback that information could not be read or written in some parts, and the amount of information on the magnetic stripe 21 was about half, which made it unusable.

Furthermore, in these conventional devices, when writing to the magnetic stripe using a magnetic head, a roller is brought into contact with the card and the card is manually moved in order to obtain a write clock corresponding to the required magnetic stripe position. The friction between the roller and the card applies rotational force to the roller, which rotates an optical timing disk and generates a clock. However, in order to obtain sufficient recording density, it is necessary to It had to be made small, and there were drawbacks such as slipping between the card and the roller, making it impossible to perform regular recording.

In view of the above, an object of the present invention is to provide a scanning head holding and driving device which is small in size, can read and write a large amount of information, and can reliably perform reading and writing operations.

The scanning head holding and driving device of the present invention includes a main frame, a recessed portion for receiving a card, which is held movably in the card insertion direction by the main frame, and abuts against the tip of the card received in the recessed portion. A card holder provided with a wall portion, a spring that biases the card holder in a direction opposite to the card insertion direction, a rack provided in the main frame in the moving direction of the card holder, and the card holder. a moving block held above the card holder so as to move along the area to be read of the card above the stand; a scanning head attached to the moving block; and a scanning head rotatably attached to the card holder. , a drive shaft provided with a spiral screw that engages with the moving block, and a pinion that is attached to the drive shaft and meshes with the rack.

Therefore, according to the present invention, the mechanism can be simplified and the overall shape can be reduced in size. Furthermore, since the scanning head stably moves along the portion to be read, the stability of reading or writing operations is excellent. In particular, there is an advantage that even if the distance traveled in the card insertion direction is small, by increasing the angle of the spiral screw of the drive shaft, the scanning head can be moved over the entire area to be read. The overall shape can be made smaller, and the scanning head can scan the entire area of the recording medium.
A large amount of information can be read or written, and since the scanning head stably scans the recording medium, the reading or writing operation is also reliable.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. In these figures, the main frame 4 has a card holder 5 and a card 2.
It is attached so as to be movable in the insertion direction (arrow A), and is biased in the opposite direction to arrow A by a compression spring 42 attached to the main frame 4. The card holder 5 is provided with a recess for receiving the card 2, and is also provided with a drive shaft 52 and a guide shaft 53. The drive shaft 52 and guide shaft 53 are attached in a direction substantially perpendicular to the direction of arrow A, and the moving block 54 is held by these shafts 52 and 53. The drive shaft 52 has a rack 4 provided on the main frame 4.
A pinion 56 that meshes with the drive shaft 52 is attached to the drive shaft 52, and the drive shaft 52 is further provided with a spiral screw. When the pinion 56 is rotated and the drive shaft 52 rotates, the spiral screw causes the moving block 54 to move along the shafts 52 and 53, that is, in a direction approximately perpendicular to the insertion direction A of the card 2 (in the direction of arrow B or the opposite direction). ). A magnetic head 55 is attached to this moving block 54.

Holding the card 2 in your hand so that the magnetic stripe 21 is approximately perpendicular to the insertion direction A, manually insert the card 2 into the recess of the card holder 5 from the magnetic stripe 21 side as shown by arrow A. Then, the tip of the card 2 comes into contact with the wall 51 at the end of the recess. When the card 2 is further pushed in the direction of arrow A from this state, the panel 42 contracts and the card holder 5 moves in the direction of arrow A. Then, since the pinion 56 rotates and moves on the rack 41 of the main frame 4, the drive shaft 52 rotates, and the moving block 54, which was initially at the left end in FIG. 3, moves to the right as shown by arrow B. In this manner, the magnetic head 55 scans the magnetic stripe 21 to perform a reading or writing operation. In this case, by increasing the angle of the spiral screw provided on the drive shaft 52, the magnetic head 55 can be made to scan the entire area of the magnetic stripe 21 even if the distance that the card holder 5 moves when the card 2 is inserted is short. be able to. When the card 2 is pulled out, the card holder 5 is pushed back by the compression spring 42, and the moving block 54 moves in the opposite direction of arrow B and returns to its original position. The rotational speed of the drive shaft 52 is detected by a speed detector 6 having a roller 61 in contact with the drive shaft 52, and a writing clock proportional to the amount of movement of the magnetic head 55 is generated.

Therefore, with this configuration, the overall shape can be made smaller. Further, even if the amount of the card 2 inserted is small, the magnetic head 55 can scan the entire area of the magnetic stripe 21, and a large amount of information can be read or written. Furthermore, since the magnetic head 55 stably contacts and scans the magnetic stripe 21, reading or writing operations can be performed reliably.
