Abstract

PURPOSE:To check easily the skew of print mediums different in length, by detecting the leading edge of a print medium and moving the print medium to a print position by a counting means. CONSTITUTION:When a bankbook A is inserted from the left, it is stopped by a stopper S. Through the bankbook A is stopped in an insertion position a1 when it is inserted correctly, there are instances where the bankbook A is stopped obliquely. In these instances, only one side of the tip of the bankbook is brought into contact with the stopper s, and the insertion of the bankbook A is detected by detecting parts 1 and 3, and the stopper S is movd upward, and the bankbook A is moved to a right print position a2 by a driving system which is not shown in figure. A detecting part 5 detects the leading edge of the bankbook A. A distance D1 between the tip of the insertion position a1 and the detecting part 5 is constant, and a number of steps of pulse motor is set preliminarily and is counted down in accordance with movement of the bankbook A until it becomes 0. The skew does not exist when the output ''0'' of a counter and the output of the detecting part 5 are conformed together, but the skew exists when they are not conformed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a print medium detection method for checking for gaps in a print medium such as a bankbook.

In automatic transaction devices such as deposit machines and withdrawal machines, when a customer inserts a passbook into the insertion slot, the data in the passbook is read, and the transaction data is printed on the passbook. When inserting a passbook, there are cases where the passbook is inserted diagonally (suki^-).One method for detecting this slippage is to detect the trailing edge of a du-printed medium (such as a passbook).
In this method, if the print media have different sizes, it is necessary to set the sizes in advance in the automatic transaction device. However, if a means to detect the leading edge of the print medium is provided,
Regardless of the size of the print medium, it is possible to confirm that the print medium is set at the print position, and to check for gaps.

The present invention has focused on the above points, and an object of the present invention is to provide a print medium detection method that facilitates checking for gaps in print media of variable length.

The present invention provides a device for inserting a printing medium such as a bankbook and printing data on the printing medium, and a means for moving the printing medium from an insertion position to a printing position, and a method based on a distance between the insertion position and the printing position. means for setting a predetermined value, a counting means for subtracting the predetermined value, a detecting means for detecting the leading edge of the print medium, and a determining means for comparing a detection signal by the detecting means with a count value by the counting means. and after moving the printing medium to a printing position, comparing and determining the count value by the counting means and the detection result by the detecting means, and checking for gaps in the printing medium. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a mechanism diagram for explaining one embodiment of the present invention, and FIG. 2 is a splitter diagram for explaining the present invention in detail.
4.6 is an amplifier, 7 is a control section, 8 is a medium control section, 9 is a per-voice moving section, 10 is a counter, 11 is a signal section, 12 is a pulse, an X%-meter, 13 is an inverter, 14. 15 is AND
Circuit, person is a bankbook, BS, B, B- is a detection signal, C is an inhalation command, D, D- is a distance, l is an error signal, r is a predetermined number of steps, G is a drive pulse, H is an output signal , l is the set completion signal, is the side wall, "l e I'm e L @ is the lamp, P is the platen, S is the stopper, town is the insertion position, and a snow is the printing position. Figure 1 (a) is a plan view for explaining the embodiment, and (b) is a side view.

In FIG. 1, when the passbook holder is inserted from the left side, the stopper 8 stops it. When it is inserted correctly, it will be at the insertion position (indicated by a broken line), but it may also stop in an oblique position as shown in the figure.

In this case, only one end of the passbook is in contact with the stopper 8, but the detection units 1 and 3 detect the insertion of the passbook person. Therefore, the stopper 8 moves upward, and as the drive system (not shown) is driven, the passbook holder moves to the right printing position -. The detection section S detects the leading edge of the passbook, and the distance DI between the tip of the insertion position and the detection section 5 is constant. When moving the passbook person using a pulse motor, the number of motor steps required to move the distance DI is set in advance. If the set number of steps is subtracted as the passbook person moves, when the passbook person reaches the detection unit 5, the subtracted value will be O.
It should be (Z0), and when it is jin, the passbook is printed at the printing position I.
This means that K has been correctly set to l■.

In FIG. 2, when the detection signals B and B reach the control section 7, an inhalation command C is issued. Toreyo) The drive control unit 8 counts the number of steps F to a counter 10 (down counter).
to have a session. This number of steps F is 9 distances as shown in FIG. , the movement of the passbook person (from the town in Figure 1) begins. On the other hand, the drive pulse G is
Since 0 is subtracted, the value of the counter 10 decreases as the passbook owner moves. The passbook holder prints at printing position a shown in Figure 1.
When the leading edge of the passbook person is detected by the detection unit 5, the detection signal Bst)9 level output from the amplifier 6 becomes "1", and the value aO (zero) of the counter 1G becomes "1". ), and the signal level of the output signal H of the signal section 11 is "
1”. Therefore, since the setting completion signal I is output from the ND circuit 15, it can be confirmed that the passbook holder has been correctly set at the printing position 1.

Even if the detection signal Bs is "1", if the value of counter 0 is not 0 (zero) (the signal level of output signal H is rOJ), or the value of counter 0 becomes O (zero), If no detection signal is obtained from the detection unit 5 (detection signal B- is "0") even though the signal level of the output signal H has reached rlJ, the error signal E is output from the five-ND circuit 14. This is output to indicate that the passbook holder is not set correctly in the print position alK.

As described above, the present invention has the advantage that by providing a means for detecting the leading edge of a print medium, it is possible to easily detect the need to set print media of different lengths.
