Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention is applicable to a business in which a continuous form is printed for one form and then cut into units and the next unit is printed. Regarding serial printers.

(Prior Art) In a serial printer, there is a task of printing a continuous form for one form, and then cutting out each unit and printing the next unit. Such a serial printer is used particularly for ticket issuing operations, and has a structure as shown in FIG.

FIG. 4 is a schematic diagram for explaining the structure of the above-mentioned serial printer, in which reference numeral 11 is a platen for supporting paper, reference numeral 12 is a carriage 12 on which a printing mechanism is placed, and the reference numeral 13 is a carriage that moves in the axial direction of the platen 11. 14 is a print head attached to the carriage 12 and performs predetermined printing by contacting the paper, 14 is a pin feed tractor for feeding the paper, and 15 is a paper cut guide for cutting the paper. ing.

In the serial printer configured in this manner, the continuous form 16 is set between the platen 11 and the print head 13 via the pin feed tractor 14. Then, the print head 13 prints the continuous paper set in this way! ! By touching 16, predetermined printing is performed. In this case, the print head 13 is configured to print information one character at a time, and after finishing printing one line using this printing method, the print head leaves the continuous form and prints the information on the platen 11 and The pin feed tractor 14 rotates and moves the continuous form 16 in the vertical direction, that is, in the direction of the arrow 17 (hereinafter, this direction is referred to as the positive direction). and,
When the continuous form 16 moves to the next printing position, the platen 11 and pin feed tractor 14 stop rotating, and the print head 13 comes into contact with the continuous form 16 to print.

In this way, when the printing of one form is completed by sequentially printing a part of the form, the continuous form M16 receives a top-of-page command (hereinafter referred to as TOP command) from the host computer (not shown), and the continuous form 16 is The eye moves to the point where it reaches the vapor cut guide 15. At this time, the serial printer is set to a deselected state, that is, an offline state, by a deselect command from the host computer.
The operator uses this vapor cut guide 15 to cut out the continuous forms in form units. Then, by operating a select/deselect switch on an operation panel (hereinafter referred to as an operation spring) (not shown), the printer is brought into a selected state, that is, placed online with the host computer, and starts printing for the next form.

In this way, after printing one continuous form, it is configured to cut out each unit and print the next unit, so it can efficiently accomplish the task, especially when applied to ticketing operations. It is something that can be done.

However, with conventional serial printers, if you print one continuous form, cut that form, and start printing the next form, you will not be able to print from near the position where the above cut n was made. Met.

This will be explained in detail with reference to FIG. That is, in conventional serial printers, when the printing of - form is completed (in this case, the characters "rPRINTERl" are the final printed characters), the continuous form 16 is printed at the perforation 21.
is moved until it reaches the vapor cut guide 15.

Here, if the distance from the printed character rPRINTERlJ to the perforation is A, and the distance from the print head 13 to the vapor cut guide 15 is L, then the continuous form has moved in the forward direction by (A+L).

Therefore, when printing starts for the next form, rPR
The printed characters INTER2J are from perforation 21 to r.
It will be printed at a position LJ apart.

In this way, with conventional serial printers, when printing the next form, the starting position is rl from the perforation.
This creates unnecessary parts in the form, which is uneconomical.

(Problems to be Solved by the Invention) As described above, in conventional serial printers, when printing for the next form is started, the printing start position is far from the perforation, so This resulted in unnecessary parts being created.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a system in which, after printing for a form is completed and cut out, when printing for the next form is started, printing can be done without creating unnecessary parts on the next form. It aims to provide a serial printer.

(Means for Solving the Problems) That is, the serial printer according to the present invention includes a form unit printing means for printing continuous forms in form units;
The printing of one form is completed by the continuous form paper feeding means that feeds the continuous form by a set length, the continuous form cutting means that cuts the continuous form at the break, and the form unit printing means. Continuous form paper feeding that controls the continuous form transfer means so that the printing start position is set at a predetermined printing position when starting printing of the next form after cutting the form at the above-mentioned cut. The present invention is characterized by comprising a control means.

(Function) In a serial printer configured as described above, when printing of the next form is started after finishing printing for one form and cutting that form at the cut line, The printing start position can now be set immediately after the above-mentioned break position. Therefore, printing for one form can be performed sequentially without creating unnecessary parts on the form.

(Example) Hereinafter, the serial printer of the present invention will be explained with reference to the following. FIG. 1 is a block diagram for explaining the configuration of a serial printer according to an embodiment of the present invention. That is, this serial printer has an interface circuit 3 that receives data from a host computer (not shown).
1, an operating spring switch circuit 32 for operating this serial printer, and a CPU (central processing bag @) that controls the entire serial printer using information from the interface circuit 31 and operating spring switch circuit 32.
33, a ROM 34 that stores a program for operating this CP LJ 33, and a RAM 35 that stores data related to this serial printer.

Also, connected to the bus of the CPU 33 are a line feed motor driver 37 that drives the line feed motor 36, a carriage motor driver 39 that drives the carriage motor 38, and a print head driver 41 that drives the print head 40. There is.

The operation of the serial printer configured as described above will be explained below with reference to FIGS. 2 to 4. Note that FIG. 2 is a flowchart for explaining the operation of the serial printer of the present invention, and FIG. 3 is an example of a continuous form printed as a result of this operation.

First, in step $1, a conditional determination is made as to whether or not a print command is being output from the host computer. Here, if it is determined that a print command has been output, a predetermined printing operation is started in step S2. That is, based on the data received by the interface circuit 31, the line feed motor 37 and the carriage motor 39
Then, the print head driver 41 is driven, and printing for the - form is started.

In this way, when the printing of the - form is completed, in step S3, a conditional determination is made as to whether or not the TPO command is being output from the host computer. Here, if it is determined that the TPO command has not been output, the process returns to step S1. On the other hand, if it is determined that the TPO command has been output, in step S4, the TOP flag set in the RAM 35 is is set.

Next, in step $5, the continuous form 16 is
) in the forward direction so that the perforation 21 of the continuous form 16 is at the position of the paper cut guide 15.

In this way, the form 16 is (A+L) in step S5.
After the line is fed in the forward direction, a conditional determination is made in step S6 as to whether or not a deselect command is being output, and if it is determined that a deselect command is being output, the select mode is switched to in step S7. Reset.

That is, by resetting the select mode, the computer is placed in an offline state with the host computer, and in this state, the operator cuts out the form.

Next, in step S8, a conditional determination is made as to whether or not the select switch is being operated. That is, it is detected whether the operator cuts out the form and operates the select switch on the operating spring to instruct the start of the next printing. By operating this select switch, the device is placed online with the host computer.

If it is determined in step S8 that the select switch has been operated, it is determined in step S9 whether or not the TOP flag is set.

If it is determined that the TOP flag is set, the continuous form 16 is sent in the reverse direction by (B) in step S10, and the TOP flag is reset.

Then, in step 311, the select mode is set, and printing of the next form is started.

Through the above-described operations, the printing result of the continuous form 16 is as shown in FIG. 3. That is, when the final printed character rPRINTERlJ of the form valve is printed, the start printed character rPRINTER2J it for the next form, perforation 2
From 1 to (L-B) wi letter position 1t is now printed, and from the perforation of conventional serial printers (L) 1
Compared to printing in a single position, the form can be used more efficiently.

The length of (B) above is set in advance, and generally (A> length is around 5 m, (L) length is 40 m).
For around J111, the length of (B) is 10 to 15111
It is set to about 1.

[Effects of the Invention] As described above, according to the present invention, - When printing of the next form is started after printing on the form valve is finished and cut out, the printing is performed immediately after the cut position. This will eliminate unnecessary parts in the form. Therefore, an economical serial printer can be realized.
