With this pulse signal, the output timing of the signal which is supplied to the head 9 is controlled. As a result, the data is recorded on the card MC with a certain level of density.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data recording device for a magnetic card. Detect the moving speed of a magnetic card that moves in contact with the
The output electrical signal is supplied to the anaerobic head at intervals corresponding to this speed.

Recently, a magnetic recording layer has been spread in the form of a strip on a plastic card, and rim! In order to record a predetermined amount of data on this type of magnetic card, which is widely used as an identification card such as the so-called AI magnetic card bank cash card, etc., in which data is recorded on the IK recording layer, wIg&record is used. A common method is to partially magnetize the magnetic recording layer by moving the magnetic card while bringing the layer into contact with a recording magnetic head, and supplying an electrical signal corresponding to the data to be recorded to the magnetic head during this time. However, in this case, there is a problem in that the magnetic card must be moved at a constant speed in order to record a fixed amount of data at predetermined intervals in magnetic recording IiI&c.

For this reason, conventional methods have been used, such as installing a servo mechanism in the motor that drives the magnetic card, and installing a flywheel on the shaft of the roller that drives the card. However, it is still not possible to obtain perfect uniformity of velocity, and the mechanism is generally complicated, making it impossible to reduce costs.

The unexploded 1uJ was proposed in view of the above points, and its purpose is to supply the magnetic head according to the detected movement of 1111 degrees even if the movement speed of the magnetic card is uneven. By adjusting the interval of the electrical signals sent by the a!, data can be recorded at a constant density regardless of the moving speed. □ Card data record:
The aim is to provide Ml placement.

The lower surface of the air card includes a mid lower guide piece 14 whose lower surface is gm, and a wiL-shaped support piece 16 connected to this lower guide piece 14. The distance between the upper guide piece 5 and the lower guide piece 14 forms a running path 17 for the magnetic card fly. In addition, as shown in FIG. 1, the end of the upper inner piece 6 on the spacer 2 side,
The ends of the lower guide piece 13 facing the lower guide piece 13 are both bent by an external force to form an entrance 18 for the AF magnetic card.

Below the upper guide piece 5, a lower support block 19 is arranged between the lower guide plates U%12. This lower support block 19 includes a roller support piece 21S2 that pivotally supports a roller such as a rubber roller facing the magnetic head 9.
2, and a sensor support piece set on the edge of this base piece. It consists of a sensor support plate that has been removed. The roller axis z7 passes through the one-piece guide piece 8, and a rotary disk is attached to the tip thereof in a perpendicular manner. This rotary disk name has a detection device such as a slit in its F-4-Y street, and this detection tA2B consists of a light emitting element 30a1 light-receiving violet excitation device arranged on the sensor support pieces A and A, respectively. 11 are provided so as to pass through the optical path of a so-called transmission type photosensor 630.

Insertion at follower 6: When the bM magnetic card inserted from the opening 18 moves and is forced into contact between the magnetic head 9 and the roller (9), the roller is inserted and the entire lower support block 19 is inserted. As a result, the spring moves downward against the spring force of the tool.

Although not shown in the figure, the magnetic head 9 includes a signal generation circuit that generates a signal corresponding to data to be edged.
And a recording amplifier for amplifying this signal and applying it to the magnetic head 9 is a! Continued.

In addition, the output of the photosensor (9) consisting of the light emitting element (equipment) and the light receiving element 30b is applied to a waveform shaping circuit, a counter, etc., and is configured to be able to detect the rotation speed of the plate name. Further, a timing control circuit for controlling the timing of the output of the i-generating circuit is connected in accordance with this rotational speed.

The operation consists of inserting a magnetic card in which a magnetic recording layer is formed in a strip shape along the long side, with the magnetic recording layer facing upward, and with the side edge aligned with the side guide piece 8. From the zero ratio in the frame, it is artificially moved in the V-do-S direction using a power means such as a Marotaba motor. The tip of the magnetic card is a
The magnetic head 916 and the roller 9 directly below the head 9 are pressed by the magnetic card and elastically move slightly upward or downward, respectively. In other words, in the magnetic card, the magnetic recording layer on the surface is placed in the gap of the magnetic head 9.
It moves 11 meters while being held between the magnetic head 9 and the rollers. Along with this, the roller force rotates clockwise in Figure 1, so the rotating disc arm connected to its pivot also rotates, and the rotating disc's detection s29 passes through the optical path of the photo sensor (equipment). do. Therefore, the light emitted from the light emitting element 30m passes through the slit as the detection lR29, becomes a pulsed optical signal, and enters the light receiving field. converted into a pulse signal.

Therefore, the output signal yl form of the photosensor (9) changes depending on the slowness of the moving speed of the magnetic card, so this is determined by a counter etc., and the rotational speed of the rotating disk, that is, ff
The movement to the magnetic card is controlled by the timing control circuit to control the output timing of the signal generating circuit which generates a signal to be supplied to the magnetic head 9 according to the speed of movement to the magnetic card. Even if the speed is uneven, it is possible to record a constant amount of data at predetermined intervals according to the speed, that is, it is possible to record data at a constant density regardless of the moving speed.

As described above, according to the present invention, there is provided a magnetic head for data la#iI, a roller disposed opposite to this magnetic head, eight rotating plates driven by and rotated by this roller, and this rotating circle. It is equipped with a photo sensor for detecting the rotation speed of the plate, and a!
This is because the timing of the electrical signal supplied to the air head is made adjustable.

Even if the moving speed of the magnetic card is uneven, there is an effect that data can always be accurately recorded at a constant ω degree. In addition, since the moving speed of the magnetic card does not have to be constant, there is an advantage that reliable recording can be performed even by a method of manually moving the magnetic card.

In addition, since uniformity of movement speed is not required, there is no need to provide a servo machine or flywheel as in the past, resulting in a more streamlined structure and contributing to cost reduction. .
