Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for transporting slips in the form of single slips by a pulse motor controlled by an electronic computer or the like.

Generally, when controlling this type of slip conveyance, a set pulse group is sent to a conveying pulse motor and a computer at regular pulse intervals by a clock oscillator, etc., and the computer etc. In order to manage the number of clocks and print slips in a predetermined format, suction (forward) and discharge (backward) processes are performed. In other words, when the slip is set in the inserter, etc. and ready to be transported in the suction direction, the suction operation is started, and the electronic computer, etc. counts the clock signals sent as interrupt signals to the control section, and When this number is reached, the suction operation is stopped. Conversely, when the printing process, etc. is completed and the paper is ready to be transported in the ejection direction, the ejection operation is started, and when the clock signal is counted in the same way and reaches a predetermined number, the ejection operation is stopped. It will be done. At this time, the clock time interval is usually the same for both suction and discharge processes. However, if the accuracy of the conveyance amount in any direction is rough, and the conveyance amount (for example, print line spacing) is set constant in one conveyance operation, the computer, etc. The clock signal to be sent does not need to be synchronized with the pulse group that drives the pulse motor, and may be 1/n (n>0). In other words, the clock signal to be sent to the pulse motor is the number of pulses determined by the amount of conveyance.
For electronic computers, etc., a trigger signal to terminate the discharge signal is sufficient. By doing so, the load factor of electronic computers, etc. can be reduced, and the processing capacity can be improved.

The present invention is based on this point of view.When inhaling, the first line is set with high precision at the printing position, and when it is ejected while printing at a predetermined line interval, when it is ejected without printing, and when it is ejected. ¹ _2o (n=0, 1, 2
). Note that the reason why ¹ _2o (n=0, 1, 2, . . . ) is used instead of 1/n (n>0) is to simplify the hardware configuration.

Examples of the present invention will be described below. 1st
In the figure, 1 is an electronic computer, 2 is an electronic computer 1
3 is an oscillation circuit that generates a signal of a specific frequency, 4 is a frequency dividing circuit that divides the frequency by 1/2n, 5 is a gate circuit that outputs a clock signal, 6 is a pulse motor This is a control circuit that drives 7.

Figure 2 shows the signal waveform of the main part, A is the output of the oscillation circuit 3, B and C are the output of the electronic computer 1, respectively.
d is an interrupt signal outputted by the gate circuit 2, and d is a clock signal outputted from the gate circuit 5 for controlling the pulse motor.

Next, the operation of this embodiment will be explained. The output of the oscillation circuit 3 is divided into one that is input directly and one that is input via the frequency divider circuit 4, and is input to the gate circuit 2. Among these inputs, those that are directly input during inhalation, that is, when the slip is in an inhalable state and the inhalation signal is on, are input as interrupt signals to a computer or the like. Further, at the time of ejection, that is, when the slip is ready for ejection, and while the ejection signal is on, the signal via the frequency dividing circuit 4 is input as an interrupt signal to a computer or the like.

The trigger for turning on the intake and discharge signals is intake and discharge of the slip.
This is when the ejection operation becomes ready. Further, the trigger for turning off is when an electronic computer or the like calculates the input pulse interrupt signal and reaches a predetermined number. On the other hand, a clock signal from the direct oscillation circuit 3 is applied to the pulse motor 7 via the gate circuit 5, regardless of whether it is inhaling or discharging.

That is, as is clear from FIG. 2D, the interrupt signal at the time of ejection is 1/2n of that at the time of intake, and the load on the computer 1 at the time of ejection is correspondingly lighter.

Although the embodiments have been explained above, according to the present invention,
The load factor of a processing machine such as an electronic computer can be reduced, and the processing capacity can be improved.
