Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a magnetic card recording/reproducing device that sends and receives signals to and from a magnetic card used in a cash card, etc. This invention relates to a moving head type magnetic card recording/reproducing device in which the card is fixed in a predetermined position after the card is carried in, and the head is moved to send and receive signals.

Configuration of conventional example and its problems FIG. 4 shows the configuration of a conventional magnetic card recording/reproducing device. In FIG. 4, the magnetic card 30 is
When the magnetic card is inserted into the magnetic card recording/reproducing apparatus through the magnetic card insertion guide member 29, it is detected by a detection sensor (not shown), and the magnetic card transport motor 31 is started. The rotation of the magnetic card transport motor 31 is controlled by a worm gear 32 and a worm wheel 3.
The speed is reduced by 3. A roller 44 is integrally attached coaxially with the worm wheel 33.
On the other hand, rollers 34 and 35 are located at opposing positions across the magnetic card transport path. This roller 34,
Reference numerals 35 indicate shafts 40 and 41 provided on levers 38 and 39 that are rotatable around shafts 36 and 37, respectively.
It is rotatable around the axis. Furthermore, roller 3
A belt 42 is stretched between 4 and 35,
The tension of this belt urges the rollers 34 and 35 toward the magnetic card side. Note that an idle roller 43 is provided at a position facing the roller 35.

When the magnetic card is conveyed between the rollers 44 and 34 and reaches a predetermined position, it is detected by a card position detection sensor (not shown), and the magnetic card conveyance motor 31 is activated according to instructions from the control section. Stop. However, since the conveyance system has inertia, the magnetic card 30 slightly overruns. The amount of overrun varies depending on the characteristics of each device and the bending or warping of the magnetic card 30. If the magnetic card 30 overruns, the magnetic head (not shown) will overrun the magnetic card 30.
When writing information on the magnetic card 30 by contacting the magnetic card 30, the information on the card may be misaligned.
This will impair the reliability of the device and, by extension, the compatibility between devices. Furthermore, when a magnetic head (not shown) runs in contact with the magnetic card 30 and exchanges information with the magnetic card 30, the magnetic card 30 is fixed by the friction between the rollers 44 and the rollers 34. Therefore, if oil or the like adheres to the surface of the magnetic card 30, there is a risk that it will shift.

OBJECTS OF THE INVENTION The present invention solves the drawbacks of the above-mentioned conventional techniques with a simple configuration, and also enables a magnetic card recording and reproducing device that allows the magnetic head to be conveyed in the front-back direction after reading data on the magnetic card. The purpose is to provide

Structure of the Invention To achieve this object, the present invention provides a moving means for moving a magnetic head from a first end to a second end of a magnetic card, and a moving means for moving a magnetic head from a first end of a magnetic card to a second end of the magnetic card. When the magnetic head reaches the second end of the magnetic card, the positioning member at the second end of the magnetic card is moved out of the conveying path by abutting against this end. It is configured to move the positioning member at the first end of the magnetic card out of the magnetic card transport path.

DESCRIPTION OF THE EMBODIMENT FIG. 1 shows an embodiment according to the present invention. 1st
The figure shows a state in which the magnetic head 2 is running along the magnetic stripe 1a of the magnetic card 1 which has already been inserted and stopped at a predetermined position.

The operation shown in FIG. 3 will be explained in detail with reference to FIG. FIG. 3A shows a state in which the magnetic card 1 is being inserted along the magnetic card insertion guide member 3. When the insertion of the magnetic card 1 is detected by a detection sensor (not shown), the magnetic card transport motor 4 is activated. The rotation of the transport motor 4 is controlled by a worm gear 5 and a worm wheel 6.
The deceleration is then transmitted to the shaft 7. A belt drive pulley 8 is attached to one end of the shaft 7 and rotates together. A magnetic card conveying belt 10 is stretched between the driving pulley 8 and the driven pulley 9, and the magnetic card 1 is held between two pressing rollers 11 and 12 and taken into the main body of the device.

Inside the device body, there is a stop member 13 that is rotatably held around a shaft 7 and biased clockwise by a spring 15, and a stop member 13 that is rotatably held around a driven pulley shaft 17 and biased counterclockwise by a spring 16. There is a displacement prevention member 14 biased in the direction. The details of the stop member 13 and the slippage prevention member 14 are shown in FIG.

On the other hand, the magnetic head 2 is held in a carriage 19 so as to be rotatable about a shaft 18, as shown in FIG. 1C. This mechanism allows the magnetic head 2 to always run in contact with the magnetic card 1 at right angles. There are two guide shafts 20 and 21 inside the device body, which guide the carriage 19.

The stop member and the anti-slip member are provided with cam surfaces 13a and 14a that abut against a surface 19a of the carriage 19, as shown in FIG. Third
FIG. A shows a state in which the surface 19a of the carriage 19 is in contact with the cam surface 14a of the anti-slip member, and the anti-slip member 14 is rotated counterclockwise.
In this state, the magnetic card contact surface 14b of the slippage prevention member 14 is retracted from the magnetic card running path 20, so that the guided magnetic card 1 can run smoothly. On the other hand, the magnetic card contact surface 13b of the stop member 13 is projected into the magnetic card running path 20 by the spring 15, and the magnetic card 1 running on the magnetic card running path 20 reaches the magnetic card contact surface 13b of the stop member 13. Then, the position of the magnetic card 1 is detected by a detection sensor (not shown), the magnetic card transport motor 4 is stopped, and the position of the magnetic card 1 within the main body of the apparatus is determined. When the loading of the magnetic card 1 is completed, the magnetic head drive motor 28 is driven. The rotation of the magnetic head drive motor 28 is decelerated by the worm 22 and worm wheel 23 and transmitted to the magnetic head drive pulley 24. The rope 25 is driven by the rotation of the drive pulley 24. The rope 25 is attached to the carriage 19 by screws 26.

FIG. 3B shows a state in which the magnetic head 2 is running along the magnetic stripe 1a of the magnetic card 1 which has been inserted and stopped at a predetermined position.

When the carriage 19 moves a predetermined distance to the left from the right end of the main body of the apparatus, the surface 19a of the carriage 19 comes off the cam surface 14a of the anti-slip member 14.
Due to the biasing force of the spring 16, the slip prevention member 14 rotates counterclockwise so that the card contact surface 14b protrudes into the magnetic card transport path 20, and the magnetic card 1 is held between the card contact surface 13b of the stop member 13 and the card contact surface 13b of the stop member 13. Sandwich. As a result, when the magnetic card 1 and the magnetic head 2 run in contact with each other, it is possible to prevent the magnetic card 1 from shifting due to the frictional force between the two.

FIG. 3C shows a state in which the carriage 19 has reached the left end of the main body of the apparatus. In this state, the stop member 13 is rotated counterclockwise by the carriage 19, and the card contact surface 13b is retracted from the magnetic card conveyance path. Normally, in the case of a regular magnetic card, the carriage 19 then travels in the right direction to the state shown in FIG. 3D, and then returns to the state shown in FIG. 3A. However, in the case of an unauthorized magnetic card, the magnetic card transport motor 4 rotates in response to instructions from the control circuit from the state shown in FIG. 3C, and the driven pulley 9
The magnetic card 1 is further conveyed to the right between the press roller 12 and the magnetic card 1, and the magnetic card 1 can be ejected and confiscated from the magnetic card ejection port 27 at the right end of the device main body.

As described above, in this embodiment, it is possible to position the magnetic card in the magnetic card recording/reproducing device and prevent the magnetic card from shifting with a simple configuration. A magnetic card confiscation function can also be performed.

Effects of the Invention As is clear from the above description, the magnetic head moving type magnetic card recording/reproducing device of the present invention protrudes into the magnetic card running path when a magnetic card is inserted;
When a stop member that determines the stop position of the magnetic card and the magnetic head for writing information on or reading information from the magnetic card come into contact with each other, the magnetic card protrudes into the magnetic card running path, and the magnetic card is displaced in the contact running direction. It is composed of a slip prevention member that prevents the magnetic card from slipping, and it has a simple structure that can position the magnetic card in the magnetic card recording/reproducing device and prevent the magnetic card from slipping. It also has the ability to confiscate magnetic cards.
