18 is a stopper, 18 is a magnetic stripe, R ₁ to R ₄ are rollers, M, P, W, W' are sensors, and K is a writing position.

As shown in FIGS. 1 and 2, the counter printer device has a printer device 1 mounted on a desk 2 that has a built-in control section 2a, and the printer device has a keyboard section 3 at the front and an insertion section at the center. 4 and a printer section 5, and a journal section 8 is arranged at the rear. As shown in FIGS. 2 and 3, the printer section 5 is composed of a print 5a and a platen 7 on which journal paper 11 is always wound. A pathway 12 for inserting and ejecting a cut medium, and a printing section 5a
It is composed of rollers R ₁ and R ₂ and rollers R ₃ and R ₄ , which are located in pairs on the upper and lower sides of the roller. roller r ₂
is retracted from the roller _R1 with a gap corresponding to the thickness of the bankbook 14, and when in operation, it is in contact with the roller _R1 and driven as shown by the two-dot chain line in the figure. Further, the shaft of the roller _R4 can be slightly retracted in the horizontal direction in the figure, and is pushed by a spring 13 in the direction of the arrow. Laura again
A stopper 17 is provided on the travel path between R ₁ , R ₂ and the printed portion 5a, and is designed to retract to open the travel path when activated. Journal section 8
It consists of a paper feed section 9 for setting a roll of journal paper 11, and a winding section 10 for winding up the journal paper 11 that has already been printed.

With this configuration, when using the printer device, when the bankbook 14 is inserted into the insertion slot 4a and transaction details such as the withdrawal amount are commanded using the push buttons on the keyboard section 3, the journal is first displayed according to the details. Printing is performed. At this time, even if the passbook 14 is inserted into the pathway 12 of the insertion slot 4a, it is blocked by the stopper 17 and cannot be moved downward. When the journal printing is completed, the already printed journal paper 11 is placed on the platen 7.
The paper is sent in the direction of arrow A from the opposite surface of the print head 6. Then, rollers R ₁ and R ₂ sandwich the passbook 14 inserted into the pathway 12, and at the same time push the stopper 1.
7 is retracted, the travel path is opened, and the passbook 14 is sent to the printing section 5a by driving the rollers _R1 to _R4 . The driving of the rollers R ₁ to _{R 4} is stopped at a position where the print head 6 faces a place on a bankbook or the like where printing is required, and printing is performed. Line breaks in printing are performed by driving rollers R ₁ to _{R 4} in reverse, and when printing is completed, the passbook 14 is moved back to the rollers.
By driving R ₁ to _{R 4} in reverse, it is discharged to the upper part of rollers R ₁ to _{R 2} , that is, to the position where it can be taken out.

In such media processing, the operation of each part is performed based on detection signals from sensors installed on the media travel path.
Passbook 14 in place for magnetic reading and writing
A conventional method for setting .

As shown in Figures 4 and 5, pathway 1
A sensor M for preventing skewing is in contact with the inside of the lower side end surface of pathway 2, and a sensor P for position setting is located further downward near the opposite end surface.
Upper magnetic head 15 in FIG.
A sensor W for detecting a writing position is arranged at the moving position. A shielding plate 16 is attached to the magnetic head 15, and it is inserted into the pathway 12 by reciprocating as shown by the arrow in the figure in parallel along the back surface of the pathway 12 at approximately the same height as the installation height of the sensor W. The magnetic stripe 18 of the passbook 14 is read and written.

With such a configuration, when the bankbook 14 is inserted into the insertion slot 4a of the pathway 12 from above, the bankbook 14 will stop when detected by the sensor P. At this time, if the passbook 14 enters diagonally and stops as shown in FIG. 6, the sensor M will not detect it, so the passbook 1
4 has to be inserted again, and it is possible to prevent reading, writing, and printing from being performed in a skewed manner. Passbook 1 thus stopped at writing position K
4 is read or written by the movement of the magnetic head 15, and the write position K is
The writing position is detected by shielding the sensor W by the shielding plate 16 that moves together with the magnetic stripe 18. To explain this writing position detection in more detail, as shown in FIGS. There is a case where the sensor W is installed near the right end, and a case where the sensor W is set near the right end, and a case where the sensor W is moved to the right from nearby, and a case where the sensor W is moved to the left from near the right end. This is the case shown in FIG. 8, and in the former case, that is, the case shown in FIG. 7, where the shielding plate 16 once passes the sensor W and then returns to detect the position where the shielding is released.

In the method described above, skew is prevented by the sensor M, but the writing position not only moves within the range allowed by the sensor M, but also the writing position K is set by the shielding plate 16, so There is a drawback that if the position of 14 is shifted, the writing position is also shifted. For this reason, if the writing position accuracy is strict, the written data may not be readable the next time, or incorrect information may be read.Especially when reading with another device, there are variations between devices, so even more precision is required. This has the disadvantage of increasing the number of errors.

SUMMARY OF THE INVENTION An object of the present invention is to provide a skew prevention system that improves the precision of writing positions to solve the above-mentioned drawbacks.

The present invention provides a magnetic medium having a magnetic stripe;
In a magnetic medium read/write mechanism comprising a magnetic head that reads and writes while moving over the magnetic stripe, a sensor is attached to the magnetic head so as to move with the magnetic head, and when the magnetic head comes to a predetermined position, the sensor is activated. This is a media skew prevention method characterized by stopping the media. By doing so, the accuracy of the writing position of the magnetic stripe can be improved.

An embodiment of the present invention will be described below with reference to FIGS. 9 to 1.
This will be explained with reference to FIG. 9a to 9c are process diagrams showing the movement of the magnetic head and sensor according to the present invention;
FIG. 10 is an explanatory diagram of skew detection, FIGS. 11a and 11b are process diagrams of writing positioning, FIG. 12 is a circuit block diagram, and FIG. 13 is a time chart. In the figure, 1
9, 20, 21 are counters, A ₁ to _{A 3} are AND circuits, N is a knot circuit, g is the skew judgment feed amount, r ₁ is the predetermined feed amount from the end face of the passbook, and r ₂ is the writing positioning feed amount. show. Further, the same parts as in FIGS. 3 to 8 are indicated by the same reference numerals.

Sensor M for preventing skew in the conventional method described above
Then, the shielding plate 16 of the magnetic head 15 is removed, and a sensor W for detecting the write position is attached to the magnetic head 15. As a result, the sensor W moves together with the magnetic head 15. However, it does not move all the steps during the movement, but stops when it reaches the end of the pathway 12, as shown in FIGS. 9a to 9c, and the magnetic head 15
It's starting to move just like that. According to this method, it is possible to check whether the bankbook 14 is skewed. 10th
As shown in the figure, even if the magnetic head 15 moves by the skew judgment feed amount g from the home position, the sensor W
When the passbook 14 is not blocked by the edge of the passbook 14, it can be determined that the passbook 14 is running diagonally. FIG. 9c shows a state in which there is no oblique movement, and the writing position K can be set by the amount of feed after the sensor W is shielded. That is, as shown in FIGS. 11a and 11b, the sensor W
The magnetic head 15 moves a predetermined feed amount r ₁ from the shielded end face of the passbook, stops once, and returns from that position by a writing positioning feed amount r ₂ to a writing start position K. This allows for highly accurate positioning.

The operation of each of the above parts is controlled by a circuit shown in FIG. The time chart is shown in FIG. That is, when the magnetic head 15 is sent along the pathway 12 from the home position, it is counted by the counter 19 by the counting pulse of the motor (not shown), and when the skew judgment feed amount g is reached, the counter 19 A signal with an output of 1 comes out and enters the AND circuit _A1 . During the feeding of the magnetic head 15, the sensor W stops at the end of the pathway 12, but unless it is shielded by the end face of the passbook 14, as shown by the two-dot chain line in FIG. 13, the output from the knot circuit N will continue to be 1. Therefore, the output of AND circuit _A1 becomes 1, which becomes the diagonal error signal, and the passbook 14
will be reset. Sensor W is passbook 1
4, the signal output entering the AND circuit _A1 becomes 0, and therefore the output from the AND circuit _A1 becomes 0. The magnetic head 15 is further sent,
The counter 20 counts the signal from the AND circuit A ₂ based on the motor counting pulse and the signal from the sensor W, and when it reaches the feed amount r ₁ from the end face of the passbook, the output becomes 1.
When the arrival signal is output, the magnetic head 15 stops. The magnetic head 15 is then sent in the opposite direction and the counter 21
counts the motor count pulse and the signal from the AND circuit _A3 based on the signal from the counter 20, and when the write positioning feed amount _r2 has been counted, a write start signal is issued.

As explained above, according to the present invention, it is possible not only to accurately detect and reset the skew of a bankbook inserted into the teller path of the device, but also to adjust the writing position on the magnetic stripe by the magnetic head to the end face of the bankbook. Since it is determined based on the distance from the target, it has the effect of significantly improving accuracy. Therefore, there is no difference in the writing position for each passbook, and even when inserted into another device, it can be read accurately regardless of variations between devices, preventing troubles due to unreadable or incorrect information being read. There is an effect that it can be done. Furthermore, since the skew prevention sensor and the shielding plate that were conventionally provided can be omitted, there is an effect that the cost is improved.
