Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a magnetic card recording/reproducing device that exchanges signals with a magnetic card used in a cash card or the like, and more specifically, to a magnetic card recording/reproducing device itself. The present invention relates to a moving head type magnetic card recording/reproducing device in which the card is fixed at a predetermined position after the card is carried into the storage device, and the head is moved to send and receive signals.

Conventional Structure and Problems Thereof FIGS. 2A, 2B, and 2C are a plan view, a front view, and a side view, respectively, showing the structure of a conventional magnetic card recording/reproducing device. FIG. 2 shows a state in which the magnetic card 1 has already been inserted and stopped at a predetermined position.

In FIG. 2, when the insertion of the magnetic card 1 is detected by a detection sensor (not shown), the magnetic card transport motor 2 is activated. The rotation of the magnetic card transport motor 2 is decelerated by a worm gear 3 and a worm wheel 4 and transmitted to a shaft 5. Axis 5
A belt drive pulley 6 is attached to one end of the belt and rotates together with the belt drive pulley 6. A magnetic card conveying belt 8 is stretched between the belt drive pulley 6 and the driven pulley 7, and the magnetic card 1 is sandwiched between two pressing rollers 9 and 10 and taken into the main body of the apparatus. When the loading of the magnetic card 1 is completed, the magnetic head drive motor 1
1 is driven. The rotation of the magnetic head drive motor 11 is decelerated by a worm 12 and a worm wheel 13 and transmitted to a magnetic head drive pulley 14. The rope 15 is driven by the rotation of the magnetic head drive pulley 14. The rope 15 is attached to the carriage 17 with screws 16.

On the other hand, the magnetic head 18 is rotatably held by the carriage 17 about a shaft 19. This mechanism allows the magnetic head 18 to always run in contact with the magnetic card 1 at right angles. An elastic leaf spring 20 and a rotating roller 21 are attached to the tip of the elastic leaf spring 20 to this carriage 17. The elastic force of the elastic leaf spring 20 urges the magnetic head 18 and the carriage 17 toward the magnetic card 1 side. are doing.

In this method, when the magnetic card 1 and the magnetic head 18 are in a non-contact area, or when the magnetic card 1 is not carried in, the magnetic head 17 is moved by the biasing force of the elastic leaf spring 20 to place the magnetic card on the main body of the apparatus. In contact with the surface 22, the sliding surface 1 of the magnetic head 18
There was a problem that 8a was worn out.

OBJECT OF THE INVENTION The present invention overcomes the above-mentioned conventional drawbacks.
With a simple configuration, the magnetic head comes into contact with the magnetic card mounting surface of the device main body in a non-contact area between the magnetic card and the magnetic head, or when the magnetic card is not carried in, causing wear on the sliding surface of the magnetic head. It is an object of the present invention to provide a magnetic card recording/reproducing device equipped with a mechanism for preventing this.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a magnetic head moving type magnetic card recording/reproducing device, which includes a carriage member that holds a magnetic head that runs in contact with the magnetic card, a carriage member that guides the movement of the carriage, and a shaft member that guides the movement of the carriage. a guide member that rotatably holds a carriage member around the center; a resilient means that rotationally urges the carriage member toward the magnetic head member;
It is comprised of a rotation limiting member that limits rotation of the carriage member around the guide member.

DESCRIPTION OF EMBODIMENTS An embodiment of the magnetic card recording and reproducing apparatus of the present invention will be described below with reference to the drawings. Figure 1 A, B,
C is a plan view, a front view, and a side view of a magnetic card recording/reproducing device of one embodiment, respectively.

In FIG. 1, the same components as those in FIG. 2 are given the same numbers.

In FIG. 1, when the insertion of a magnetic card 1 is detected by a detection sensor (not shown), a magnetic card transport motor 2 is activated. The rotation of the magnetic card transport motor 2 is decelerated by a worm gear 3 and a worm wheel 4 and transmitted to a shaft 5. Axis 5
A belt drive pulley 6 is attached to one end of the belt and rotates together with the belt drive pulley 6. A magnetic card conveying belt 8 is stretched between the belt drive pulley 6 and the driven pulley 7, and the magnetic card 1 is held between two pressing rollers 9 and 10 and taken into the main body of the device. When the loading of the magnetic card 1 is completed, the magnetic head drive motor 1
1 is driven. The rotation of the magnetic head drive motor 11 is decelerated by a worm 12 and a worm wheel 13 and transmitted to a magnetic head drive pulley 14. The rope 15 is driven by the rotation of the magnetic head drive pulley 14. The rope 15 is attached to the carriage 17 with screws 16.

On the other hand, the magnetic head 18 is rotatably held by the carriage 17 about a shaft 19. This mechanism allows the magnetic head 18 to always run in contact with the magnetic card 1 at right angles. A resilient leaf spring 20 and a rotating roller 21 are attached to the tip of the resilient leaf spring 20, and the resilient force of the resilient leaf spring 20 urges the magnetic head 18 and the cartridge 17 toward the magnetic card side. ing.

Inside this device, the carriage 17 rotates,
When the magnetic card 1 and the magnetic card 1 are in a non-contact area, or when the magnetic card 1 is not carried in, the biasing force of the elastic plate spring 20 causes the magnetic head 1 to
A rotation limiting member 23 is provided so as not to come into contact with the magnetic card placement surface 22 of the device main body. This rotation limiting member 23 is connected to the magnetic card 1 at both ends of the device.
In the non-contact area of the magnetic head 18, the magnetic head 18 contacts the carriage 17 so that the sliding surface 18a of the magnetic head and the magnetic stripe 1a surface of the magnetic card 1 are approximately at the same height. 1
The contact area 8 comes into contact with the carriage 17 only when the magnetic card 1 is not being carried in, thereby preventing contact between the magnetic head 18 and the magnetic card mounting surface 22.

In this way, according to this embodiment, the magnetic head 1
This is very effective because it prevents the magnetic head 18 from being worn out due to contact between the magnetic head 8 and the magnetic card mounting surface 22.

Effects of the Invention As is clear from the above description, according to the present invention, a magnetic head moving type magnetic card recording and reproducing device includes a carriage member that holds a magnetic head that runs in contact with the magnetic card, and a carriage member that holds a magnetic head that runs in contact with the magnetic card, and a carriage member that holds a magnetic head that runs in contact with the magnetic card. a guide member for guiding and rotatably holding the carriage member about its axis; a resilient means for rotationally biasing the carriage member toward the magnetic head member; It is composed of a rotation restriction member that restricts rotation, and has a simple structure that allows the magnetic head to be placed in the non-contact area of the magnetic card and the magnetic head, or when the magnetic card is not carried in. This can prevent the sliding surface of the magnetic head from being worn out.
