Description

[Detailed description of the invention] Media that is subjected to processing such as printing by the invention & L bookkeeping machine,
In particular, the present invention relates to a media control device for media with folds, such as bank passbooks, on which magnetic stripes are attached.

The method of pasting a magnetic stripe on the surface of a bank passbook to memorize the account number and deposit balance information, and then reading it in a recorder or writing new information into it has not been put to practical use. There is.

Generally, when a recording machine processes a medium having a magnetic stripe, a magnetic head driving magnet is excited to press the magnetic head toward the medium at the same time as a command to take in or eject the medium.

In such cases, the magnetic head vibrates when it passes through the creases of a bank passbook, etc., making subsequent reading or writing operations impossible, and the lifespan of the magnetic head is also shortened. There is.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, and for this reason, the medium control device proposed in the present invention is equipped with a medium detector that detects when the medium has reached a predetermined position, and the medium is moved by the detection signal of this detector. The medium detector includes a timer circuit for stopping the drive motor for a predetermined period of time and a drive circuit for exciting the magnetic head drive magnet in response to the detection signal to press the magnetic head toward the medium. It is characterized by being connected to.

The present invention will be further described below with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of an embodiment of a medium control device according to the present invention.

The medium 1 is sucked in or discharged by a medium transfer roller 7 that is interlocked with a transfer drive pulse motor (not shown).

2 is a fold of the medium 1, and 5 is a magnetic stripe.

3 is a magnetic head, and 4 is a magnet for driving the magnetic head.

Reference numeral 6 denotes a medium detector, which is arranged at a position such that when the magnetic head 3 reaches the read start position or write start position of the magnetic stripe 5, it detects the edge of the medium 1 and issues a detection signal.

This medium detector 6 may be, for example, a transmission type sensor using a light emitting element and a light receiving element.

The operation when the medium 1 is discharged from the bookkeeping machine as indicated by arrow A will be explained.

When a discharge command is issued, the pulse motor is driven, the medium transport roller 1 rotates, and the medium 1 is discharged in the direction of arrow A.

At this time, the magnetic head driving magnet 4 is not excited and the magnetic head 3 is located away from the medium 1.

Therefore, even if the fold line 2 of the medium 1 passes the magnetic head 3, the magnetic head 3 does not engage with the fold line 2 and does not vibrate.

When the magnetic hand 3 reaches the writing start position of the magnetic stripe 5, the medium detector 6 detects the edge of the medium 1 and issues a detection signal.

This detection signal excites the magnetic head driving magnet 4, and the magnetic head 3 is pressed against the medium 1 side.

At the same time, the drive of the pulse motor is stopped by the detection signal, and the transport of the medium 1 is stopped for a predetermined period of time determined by the timer circuit.

A timer time is set so that vibrations caused by the collision of the magnetic head 3 with the medium 1 during this stop time are eliminated.

When the magnetic hand 3 becomes stationary and stable after a certain period of time determined by the timer circuit has elapsed, the pulse motor starts driving again and ejects the medium 1 while writing information on the magnetic stripe 5. FIG. 2 is a time chart of the present invention described above. B is the output of the medium detector, C represents the drive of the pulse motor, and D represents the operation of the magnetic head driving magnet.

When the medium detector detects the edge of the medium at point e and issues a detection signal, the pulse motor stops driving after a time t, and at the same time, the magnetic head driving magnet is excited.

FIG. 3 is a schematic block diagram of a medium control device according to the present invention, in which a detection signal f from a medium detector acts on a drive circuit 8 via a discrimination circuit 1, and is applied to a drive circuit 8 via an amplifier 9 to drive a magnetic head. The magnet 10 is excited.

The detection signal f simultaneously enters another discrimination circuit 11 via a timer circuit 15, acts on a drive circuit 12, and controls a pulse motor 14 via an amplifier 13.

g and h are a signal indicating the suction and discharge directions of the pulse motor and a pulse motor start signal, respectively.

By using the above-mentioned medium control device, the magnetic head will no longer engage with the folds of the medium being transported and vibrate.
Therefore, the negative effects of vibrations of the magnetic head on reading/writing accuracy, shortening of life, and increased load on the pulse motor when passing through folds can be avoided.
