In a printer that starts on printing on instructions from an upper unit, a head-finding distance memory 3 and a head-finding distance counter 21 are provided. The sheet feeding controller 2 controls the sheet feeder 1 and moves the sheet from the standard postition to a position specified by an operator. The head-finding distance counter 21 counts the distance of the moving, and the head-finding distance memory 3 keeps, on instructions by the operator, the values made by the counting by the head-finding distance counter 21.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer device.
When using preprinted paper, there is a need to facilitate paper loading.

[0002]

2. Description of the Related Art Recent printer devices have a paper autoload function. Press the "auto / manual" button on the operation panel to enter the manual mode, hang the paper on the sprocket, and press the "paper set" button. Then, the paper feeding control unit controls the paper feeding mechanism to automatically set the paper at the standard position. The standard position of the paper is typically the leading edge of the paper one inch past the printhead. This is because there is a paper cutter at this position, and so-called 1-inch cutting can be performed when the page is changed.

Preprinted paper is often used in a form issuing system using a computer. This has advantages such as high speed, use of colored paper, low total cost, and easy handling even when the form of the paper is specified, compared to the case where the frame is computer-printed on the blank paper using the form overlay method. Because there is. This tendency is even more remarkable in the case of a serial dot printer having a low speed.

However, when pre-printed paper is used, the problem of paper alignment occurs. It is necessary to adjust the printing start point so that printing can be performed just within the preprinted frame. In particular, in the case of a form with a tight pre-printing framework and no misalignment margin, it is difficult to align each time by trial and error. Also, if there is only one type of pre-printing paper, it is empirical. The operator is accustomed to the position alignment operation, but it is difficult for the operator when there are many types of paper.

[0005]

In the prior art, the initial setting position of the paper of the printer is fixed, and in order to position the head of the printer at a predetermined position of the preprinted paper, it is manually aligned. There is a problem that it is difficult.

SUMMARY OF THE INVENTION It is an object of the present invention to realize a printer device that can easily set the initial paper setting position for each type of paper.

[0007]

FIG. 1 is a block diagram showing the principle of the present invention. The printer device is provided with the cue distance storage unit 3 and is configured to shift the print start point according to the value held in the cue distance storage unit 3 from the standard print start position to start printing.

A second aspect of the invention has a paper feed mechanism 1 and a paper feed control unit 2, and the paper feed mechanism 1 has a paper leading edge detector.
11, the paper feed control unit 2 knows the position of the paper leading edge from the signal from the paper leading edge detector 11, controls the paper feeding mechanism 1 to move the paper a predetermined distance, and feeds it to the standard position. In a printer device that starts printing when there is an instruction from the device, a cue distance storage unit 3 and a cue distance counter 21 are provided, and a paper feed control unit 2 controls the paper feed mechanism 1 to give an instruction by an operator. Move the paper from the standard position to the position, and the cue distance counter 21
The distance when moved is counted, and the cue distance storage unit 3 is configured to hold a value according to the value counted by the cue distance counter 21 according to an instruction from the operator.

A third aspect of the invention is the same as the first or second aspect of the invention, in which the sheet type selection section 4 and a plurality of cue distance storage sections 3a are provided.
3 to 3n are provided, and the paper type selection unit 4 has a cue distance storage unit 3a to 3n for inputting a cue distance, or a cue distance storage unit 3a to 3n for sending a cue distance to the paper feed control unit 2. Select.

[0010]

The cue distance storage unit 3 holds a value relating to the deviation when the print start position is different from the standard position, and the printer device uses this value to obtain a non-standard value required when using preprinted paper or the like. Printing can be performed from the print start position of.

In the second aspect of the invention, the nonstandard sheet position is set in the actual state, and the value relating to the deviation from the standard position at that time is set in the cue distance storage section 3, so that the nonstandard sheet position is set. The position can be set easily.

In the third aspect of the invention, a plurality of non-standard sheet position settings are prepared, and it is possible to cope with a large number of sheet types.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is an explanatory diagram of the configuration of the embodiment. The same parts as those in FIG. 1 are designated by the same reference numerals. In the figure, reference numeral 1 denotes a paper feed mechanism, which feeds a paper 16 by a sprocket 13 under the control of a paper feed controller 2 and a print head 15 prints at a position of a platen 14. A paper pressing plate 12 has a photosensor 11 for detecting the leading edge of the paper and a paper shortage, and the detection signal b thereof is input to the paper feed control unit 2. Reference numeral 17 denotes a paper cutter, which allows the operator to cut out the printed paper at this position.

The operation panel 22 transmits an operator's manual operation instruction regarding sheet feeding to the sheet feeding control section and the like, and the sheet feeding control section 2 operates the sheet feeding mechanism 1 in accordance with the instruction.
FIG. 3 shows an example of the operation panel.

The flow of processing according to an instruction from the operation panel will be described below. 1: Memory for cue position The operator needs to align the paper once for each paper.

First, the "auto / manual" button on the operation panel 22 is pressed to enter the manual mode. When the mode is changed to the manual mode, the paper designation mode is entered and the paper number is 00. Place the paper on the sprocket 13 and press the "Paper Set" button to feed the paper to the standard position. The paper feeding control unit 2 sets the paper at the standard position by controlling the paper leading edge detection signal b so as to feed a predetermined distance.

In this state, the type of paper is designated by the paper number. (If necessary, press the "Paper / Distance" button to enter the paper specification mode.) Specify the paper number with the "▽" and "△" buttons. Next, the "paper / distance" button is pressed to enter the distance designation mode, and the paper is fed to the cue position of the paper by the "▽" and "△" buttons. By operating the “∇” and “Δ” buttons, the paper feed control unit 2 issues paper feed pulse signals a + and a− to the paper feed mechanism 1. Based on these signals, the paper feed mechanism 1 moves the paper in the forward and reverse directions in units of sprocket movement pitch (usually 1/60 inch). During this time, the cue distance counter 21 counts the number of movement pitches.

When the position is determined, the "position storage" button is pressed to instruct the paper feed control unit 2 to "store the position". The paper feed control unit 2 stores a paper number and a cue distance counter in predetermined cue distance storage units 3a to 3n via the paper type selection unit 4.
Set the count value of 21, that is, the cue distance as a pair. It should be noted that trial printing may be necessary depending on the structure of the printer device in order to accurately determine the cue position.

The following may be adopted. When the paper is set to the cueing position, the “position storage” button is pressed, and the “position storage” is instructed to the paper feed control unit 2, the paper feed control unit 2 causes the paper feed mechanism 1 to start the reverse rotation operation to load the paper. Return to standard position. The cue position counting circuit counts the distance from the start of reverse rotation to the standard position. This value is output to the cue distance storage unit. 2: Normal paper set = automatic cueing The process for autoloading paper is as follows. First, hang the paper on the sprocket, then "automatic / manual"
Press the button to enter the manual mode, press the "Paper / Distance" button to enter the paper mode, and specify the paper number with the "▽" and "△" buttons. When this designation is made, the sheet number and the cue distance stored in the cue distance storage section are displayed. Here, when the "paper set" button is pressed, the paper feed control unit operates the paper feed mechanism 1 to move it to the standard position, and further moves it by the movement pitch number of the cue distance. Thus, the automatic loading of the sheet based on the cueing position information stored for each sheet is completed.

The content stored in the cue distance storage unit may be a moving distance from the paper leading edge detection point to a predetermined position (cueing position) instead of the moving distance from the standard position as described above. Of course, the control at the time of automatic loading of paper must be adjusted accordingly.

Although the above description has been made on the premise that continuous paper is used, the same applies to single-cut paper. The only difference is that the sprocket of the paper feed mechanism becomes a roller, and cueing is performed for each single cut.

In addition to the method of setting the contents of the cue distance storage unit by the above-mentioned operation, a method of directly setting by the operator or a method of loading from the host computer may be used.

[0023]

As described above, according to the present invention,
Since the cue distance matched to the pre-printed paper can be stored and the paper is automatically loaded according to the pre-printed paper, it is possible to realize a printer device that can reduce the burden of setting the paper on the operator. .
