JPS58167166A - Printer for bill number - Google Patents

Abstract

PURPOSE:To obtain a printer for bill number having a system in which a means to obtain starting time and prohibiting time of print operation and a circuit to control the print operation by temporarily stopping a feeding path from said times are provided, control on the feeding system is simplified, and limit on the feeding interval of bills is removed. CONSTITUTION:When a bill 11 already printed passes through a photoelectric switch 22, a signal S22 is sent out to a control circuit 23 in which print operation starting time is obtained from a signal S21 by the photoelectric switch 21 and a prohibiting time for the temporary stoppage of a feeding path 11 is obtained, because of prohibiting time for printing operation, or the time when defective bills are accumulated in an accumulating box 14, from the signal S22 of the photoelectric switch 22. In case where the prohibiting time of print operation is lapped with the starting time of print operation, the startup of print operation and the temporary stoppage of the feeding path 11 are put off until the prohibiting time of print operation is released. Even when print operation is put off during only the time period, the printing of a series of numbers on the bills after reading by a printer 12 can be attained sufficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a device that optically reads characters written on a form and stores the 4-bit data on an output medium such as a floppy disk or a floppy disk, and allocates the data to the read form. The present invention relates to a form number printing device that prints a serial number on a form.

In the case of a conventional form numbering device that temporarily stops the conveyance system and prints a serial number on the form, a form may be defective in the form collection box depending on the position of the form that has already been printed on the conveyance path at the time of the temporary stop. There were cases where they were accumulated.

This point will be explained with reference to FIG.
, the form 11 that has been read by the optical character reading device 10 moves on the conveyance path 13 and passes through the photoelectric switch 21.
and reaches the printing device 12.

A signal generated when the form 11 crosses the photoelectric switch 21 is given to the printing device 12 as a printing trigger signal, and after a certain period of time, that is, when the form 11 reaches the printing device 12, the printing device 12 temporarily stops the conveyance path 13. After printing is completed, the conveyance path 13 is driven again to move the form 11 and accumulate it in the form accumulation box 14.

There is a distance between the printing device 12 and the collection box 14, and there are several forms on which serial numbers are already printed on the conveyance path between them. Therefore, when the conveyance path 13 is temporarily stopped in order to perform a printing operation with the printing device 12, all the printed documents existing on the conveyance path between the printing device 12 and the collection box 14 are moved to their respective positions on the conveyance path. Pause at . If the printed form is temporarily stopped on the conveyance path 13 with only a few millimeters left at the trailing edge of the form, that is, if it is temporarily stopped at the position of the form 15 in FIG. Even if the drive is re-driven, the driving force for the form 15 is weak, so that the form 15 is in a stacking failure state such as a rising state as shown in FIG. 1 (bl).

In conventional devices, in order to avoid the above-mentioned stacking failure state, the stacked slips 11 are placed in a state where no slips are present on the conveyance path between the printing device 12 and the stacking box 14, that is, after the printed slips are stacked in the stacking box 14. The conveyance interval of the form may be increased so as to cross the photoelectric switch 21, or the conveyance path 13 may be divided into a system for the printing device 12 and a system for the collection box 14 to perform conveyance control and printing operation control. was. As described above, with conventional apparatuses, it has been difficult to print serial numbers on forms without complicating the control of the conveyance system and without increasing the interval between forms, that is, without reducing the processing speed.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a form number printing device that eliminates limitations on the transport interval of forms without complicating the control of the transport system.

According to the present invention, there is a means for obtaining a printing operation start time corresponding to a form for which reading has been completed and a printing operation is to be performed, and a means for obtaining a printing operation prohibition time corresponding to a form existing on a conveyance path and for which a printing operation has already been completed. A document number printing device is obtained, which includes a circuit for controlling execution of the printing operation by temporarily stopping the conveyance path from the printing operation start time and the printing operation inhibition time.

Next, an embodiment of the present invention will be described with reference to FIG.

In FIG. 2, parts corresponding to those in FIG. 1 are designated by the same reference numerals. When a completed form crosses the photoelectric switch 22, a signal 822 is output to the control circuit 23. The control circuit 23 determines the printing operation start time from the signal 821 from the photoelectric switch 21K, and calculates the printing operation start time from the signal 82 from the photoelectric switch 22.
From 2, the printing operation time, that is, the time during which the temporary stop of the conveyance path 11 is prohibited since defective forms are accumulated in the accumulation box 14 is determined. If the printing operation inhibition time and the printing operation start time overlap, the start of the printing operation, that is, the temporary stop of the conveyance path 11, is postponed until the printing operation inhibition time is canceled.

Since the printing operation prohibition time is the time during which the trailing edge of the printing completed form is on the conveyance path 11 by several millimeters, even if the printing operation is delayed by this time, the printing device 12 will not be able to print the serial number on the cyst removal completed form. It is quite possible. Incidentally, if the printing operation prohibition time and the printing operation start time do not overlap, the printing operation is executed immediately.

The details of the operation will be explained below. Signal 821 is delay circuit 3
3 outputs a signal 833. A signal 833 is sent to the transport path 1 in order for the printing device 12 to perform reading and printing operations on the completed form.
1 is temporarily stopped, that is, the printing operation start time.

When the signal 833 is output, the 7-rip 70 tube 34 causes the signal 834 to become I'''.

On the other hand, when signal 22 is output, signal 837 is output by monostaple multivibrators 36 and 37.
When the signal 4837 is @1'', it is the time to delay the temporary stop, that is, the print operation prohibition time.If the signal 838 is @0'' by the NOT circuit 38, the print operation prohibition time is 1''.
If so, it becomes a signal to cancel the print operation inhibited state. Therefore, AN
The signal 839 from the D circuit 39 is not output during the print operation prohibition time, but is output after the print prohibition state is released.

The signal 839 serves as a signal for the printing device 12 to temporarily stop the conveyance path 11 and start the printing operation, and also to
o, serves as an input signal to the printer 34 and sets the signal 834 to a state of 10''.In this way, if the printing operation start time and the printing operation inhibition time overlap, the printing device 12 continues the printing operation until the inhibition state is canceled. will be postponed.

In addition, if the printing operation start time and the printing operation inhibition time do not overlap, when the signal 834 becomes '1'', the signal 8
Since the signal 38 is in the '1' state, the signal 839 will be output immediately.Therefore, at the printing operation start time, the printing device 12
The transport path 11 is temporarily stopped and printing is executed.

Therefore - the transport path 11 between the printing device 12 and the collection box 14
Regardless of how many printed forms are present on the top, the printing device 12 can easily temporarily stop the transport path 11 for printing without causing a stacking failure in the stacking box 14.

In addition, if there is only one printed completed form on the conveyance path, remove the photoelectric switch 22 and replace the photoelectric switch 21.
Similar control is possible by obtaining the signal 822 from .

As described above, according to the present invention, it is possible to easily realize a form number printing device that eliminates restrictions on the conveyance interval of forms using a single conveyance system and stabilizes the state of accumulation of forms on an accumulation bridge.
