Abstract

PURPOSE:To reduce the burden of an operator, by a method wherein, a means directing the ON/OFF of a printing action at the detection of the trailing end of a continuous paper and directing a printing amount after the detection of the trailing end is provided, and with the direction of keeping on the printing action the printing action is kept on by the directed printing amount after the detection of the trailing end of the continuous paper. CONSTITUTION:With an input of a detection signal which is outputted from a paper end switch 16 through an I/O port 28, a CPU 21 checks whether or not a flag stored in a flag storage area 24a of a RAM 24 is set to ON. If the flag is set to ON, a printing action is kept on for every line by the printing amount stored in a printing amount storage area 24b of the RAM 24. On the other hand, if the flag is set to OFF, a printing action is stopped after the detection of the trailing end of a continuous paper 13 and the continuous paper 13 is discharged. In this construction, a printing after the detection of the trailing end of the continuous paper can be carried out without a printing direction at every one-line printing; thus, the burden of an operator can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a printer device most suitable for printing on continuous paper.

(Prior Art) Generally, continuous paper used in a printer device is set on a tractor that feeds the paper, and after being sent between a print head and a platen via this tractor, it is printed in one line by the tractor and platen. sent every time. Normally, the tractor is equipped with a vapor end switch that detects the end of the continuous paper, and when this vapor end switch detects the end of the continuous paper, the printing operation is stopped and the continuous paper is ejected. It is composed of

However, when this continuous paper is used to print a predefined format, such as a slip, as shown in Figure 5, the continuous paper leaves a few lines of print near the end of the continuous paper. A situation arises in which the gas is discharged. This is caused by the distance between the vapor end switch and the print head, and in the case of continuous paper shown in Figure 5, when the vapor end switch detects the end at point A, the print head position is at point B. It is in. Therefore, the continuous paper is ejected without being printed by the distance between point A and point B, that is, the distance between the Baber end switch and the print head.

Therefore, conventional printer devices are equipped with an override function in consideration of such a situation. This override function is to continue the printing operation line by line as long as printing is possible even after the end of continuous paper is detected.

However, this override function does not allow the operator to check the printing status after detecting the end of continuous paper.
It is necessary to specify printing (by using a switch) for each line of printing, which has the drawback of placing a burden on the operator.

<Problems to be solved by the invention> As mentioned above, in the past, after detecting the end of continuous paper, if you wanted to continue printing in a rough manner, you had to specify printing for each line, which placed a burden on the operator. There was a drawback that it gave

The present invention has been made in view of the above points, and is
An object of the present invention is to provide a printer device capable of printing after detecting the end of continuous paper without putting a burden on a printer.

[Structure of the invention] (Means and actions for solving the problem) That is,
A printer device according to the present invention is a printer device that stops a printing operation upon detection of the end of continuous paper, and specifies whether to stop or continue the printing operation when the end of the continuous paper is detected, and determines the amount of printing after the end of the continuous paper is detected. The method is characterized in that, when the continuation of the printing operation is specified by taking the specified means, after the end of the continuous paper is detected, the printing operation is continued for the specified printing amount. The configuration enables printing after detecting the end of continuous paper without specifying printing for each line, thereby eliminating the burden on the operator.

(Embodiment) Hereinafter, a printer device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing the configuration of a printing section, in which numeral 11 is a platen and 12 is a print head.

Continuous paper 13 is set on a tractor 14 that feeds the paper, and after being sent between the print head 12 and platen 11 via this tractor 14, it is pressed against the platen 11 by a pail roller 15 and then moved between the tractor 14 and the platen 11. It is sent line by line by the platen 11. The tractor 14 is equipped with a paper end switch 16 that detects the end of the continuous paper 13. When the paper end switch 16 detects the end of the continuous paper 13, the printing operation is stopped and the continuous paper 13 is ejected. is configured to be

FIG. 2 is a block diagram showing the circuit configuration of the egg-breaking system, including the CPU 21 which controls the entire printer, the connecting system 22, the RoM 23, the RAM 24, the interface 25, the printing operation drive section 26, and the printing mechanism control section. 2
7 and I10 boats 28 are connected respectively.

The ROM 23 stores data such as programs for driving the CPU 21. The RAM 24 is responsible for transmitting and receiving data to and from a host device (not shown), which will be described later.

The print operation drive section 26 converts the print data into a drive signal at the actual print level according to c p U 21 . The printing mechanism control section 27 executes a printing operation by driving a carriage motor, a paper feed motor, etc. (not shown) in accordance with a signal supplied from the printing operation driving section 26.

The I10 port 28 controls the input of the dip switch 29 and the paper end switch 16. This dip switch 29 consists of four switches 298 to 29e,
The switch 29a is configured to specify whether to stop or continue the printing operation when the end of the continuous paper 13 is detected, and the switches 29b to 29e are configured to specify the amount of printing after the end of the continuous paper 13 is detected.

The operation of the printer device configured as described above will be described below with reference to the flowcharts shown in FIGS. 3 and 4.

FIG. 3 is a flowchart showing the initialization routine.

That is, when the power is on, the CPU 21 detects whether or not the switch 28a of the dip switch 29 is turned on (step A1), and if the switch 28a is turned on, in other words, it turns on the flag indicating that the continuous paper 13 is being printed.
(Step A2>) Next, the values of the switches 24b to 24e of the dip switch 29 are read (step S3), and the print amount set by the switches 24b to 24e is stored in the print amount storage area 24b of the RAM 24. (Step 84). On the other hand, in step A1, if the switch 28a is turned OFF, that is, if stopping the printing operation upon detection of the end of the continuous paper 13 is specified, the flag is set to OFF ( Step A+).In this case, if the print amount is stored in advance in the print amount storage area 24b of the RAM 24, the above print amount is cleared.

In this way, the printing operation is started after the printing operation is stopped/continued after the end of the continuous paper 13 is detected, and the printing amount is set accordingly. That is, CP LJ 2
1 is a print operation drive unit 26 and a print mechanism control unit 2 based on print data received via an interface 25.
7 and prints while feeding the continuous paper 13 line by line. In this case, continuous paper 13 is fed between print head 12 and platen 11 via tractor 14 . Here, when the paper end switch 16 disposed on the tractor 14 detects the end of the continuous paper 13, the fourth
Execute the process shown in the figure.

FIG. 4 is a flowchart showing a processing routine after detecting the end of continuous paper. That is, CPLI21 is I10
When the detection signal output from the paper end switch 16 is input via the boat 28, it is checked whether the flag stored in the flag storage area 24a of the RAM 24 is set to ON (step B1), and the flag is turned ON. If set to , print amount storage area 2 of RAM 24
The printing operation for the printing amount stored in 4b is continued line by line (steps 82 and 83). On the other hand, in step B1, if the flag is set to OFF, after the end of the continuous paper 13 is detected, the printing operation is stopped and the continuous paper 13 is discharged.

In this way, according to this embodiment, it is possible to continue the printing operation after detecting the end of continuous paper and specify the printing amount at that time before printing starts, so that printing can be performed even after the end of continuous paper is detected. If this is clear and the printing amount is also known, it is sufficient to specify these before printing starts. Therefore, it is no longer necessary to designate printing for each line while checking the printing status after detecting the end of continuous paper as in the past, and the burden on the operator can be eliminated.

Note that in this embodiment, the designation/continuation of the printing operation after detection of the end of continuous paper and the designation of the printing amount were carried out using a dip switch, but the present invention is not limited to this, and for example, an operation panel switch or It may be implemented by a command from the host device, and even with this configuration, the same effects as in the above embodiment can be obtained.

[Effects of the Invention] As described above, according to the present invention, a means is provided for specifying stop/continuation of the printing operation when the end of continuous paper is detected, and a means for specifying the amount of printing after the end is detected, so that the continuation of the printing operation is performed. is specified, the printing operation continued for the specified amount of printing after the end of the continuous paper was detected, so it was possible to print after the end of the continuous paper was detected without putting any burden on the operator. Become.
