JPH01283177A - First character printing position change-over system of printer - Google Patents

Abstract

PURPOSE:To set the same printing position as a conventional one at one position and to perform printing at the other position in such a state that a printing position is enlarged, by combining the position of a left end guide becoming a reference position at the time of the insertion of the slip on a slip table with the state of a switch. CONSTITUTION:In the printing indication of the first printing position, at first, a sensor detects whether the position of the left end guide becoming a reference position at the time of the insertion of the slip on a slip table 3 is on the right 6a or on the left 6a'. By combining the positions 6a, 6a' of the left end guide with the presence of the change-over of the setting of a separately provided switch, a microprogram for the feed control of a printing head is selected to determine the first printing position. By this method, printing can be applied to expendables fitted to the measure of a previous printer. Further, printing can be applied even to expendables having a new measure enlarged in a printing range by the setting of the switch and the free selection of the positions 6a, 6a' of the left end guide.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a first character position of a printing device, and particularly to a switching method suitable for a method of setting a plurality of first print positions.

[Conventional technology]

Conventionally, the leftmost first character printing position of characters to be printed is fixed to a single dimension.

In addition, related to this type of device.

For example, Japanese Utility Model Application Publication No. 62-83658 can be mentioned.

[Problem to be solved by the invention]

In the prior art described above, the first character printing position shown in FIGS. 5 and 6 is fixed at a constant size of Lx for a single sheet and 52 dimensions for a continuous sheet.

This type of printing device is positioned as a successor to the previous generation even when new models are improved or added with functions, and is required to satisfy the specifications of the previous generation and expand the specifications.

In other words, when printing on formatted consumable specifications (printing paper) such as frames, it is necessary to align the first print position, and it is also possible to expand the print range by moving the first print position to the left. However, in the past, it has not been possible to satisfy both the expansion of the printing range.

An object of the present invention is to enable printing at one position by changing the position of the left end guide of the ticket stand, in combination with this position, to print at the same printing position as before at one position, and at the other position at an enlarged printing position. be.

[Means for solving problems]

As shown in FIG. 2, there is a method in which the left end guide is switched to the left in order to increase the number of sheets that can be handled.

The above purpose is to change the position where this left end guide is switched to the left and right and the fourth
As shown in the figure, this is achieved by combining the settings of separately provided switches to change the setting of the first printing position to a setting that satisfies the conventional specifications and expands the printing range. .

[Effect]

To designate printing at the first printing position, first, a sensor detects whether the left end guide of the cut sheet is positioned on the right or left side.

By combining the position of this left end guide and whether or not the setting of a separately provided switch has been changed, a microprogram for controlling the feed of the print head is selected and the first printing position is determined.

By doing this, it is possible to print on consumables that meet the specifications of the previous generation printing device, and also to set the switch and left edge guide for consumables with new specifications that have expanded the printing range. You can freely select and print depending on the position.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6. FIG. 1 is a block diagram of a printing device equipped with the first character printing position switching system of the present invention, in which 1 is a print head, 2 is a cut conveyance/feed roller, and 3 is a cut sheet when feeding cut paper. The stand, 4 is a tractor for conveying continuous paper in a pull tractor type, 5 is a platen that receives the impact force of the print head, 11 is a single sheet, and 12 is a continuous paper.

FIG. 2 shows the cut board, and 6a is the left end guide which is a guide when printing and inserting the cut, and shows the position set on the right side. Also, 6a' indicates the position set on the left side, like this, the left end guide is 6a.

By setting the position to 6a', the medium size of the paper can be changed from Q to L.
can be expanded.

Figure 3 shows a cross section in the width direction of the cut board, and the left end guide engages with the cut board main body and slides.Although not shown, a sensor is provided to detect the position of the left end guide. Then, the positions 6a and 6a' are separated.

Next, a method of switching the first printing position will be explained with reference to FIGS. 4 to 6. A switch 7 is provided, and the setting of this switch 7 is "ON".

Depending on the OFF condition and the A-D state of the flow,
This method determines the printing position of the first character to be printed.

In other words, when the switch 7 is set to "None" and the left end guide position is both left and right, the first printing position Ll=i of the single sheet is set.
1.43nn, first printing position Lz of continuous paper: 24.1
3 mm, and this position is set in accordance with the conventional, that is, previous generation consumable product specifications. In addition, if there is a consumable specification that corresponds to the expansion of the specification, the switch 7 is set to "ON", and the position of the left end guide can be set to the left or right, and the first printing position can be set.

In the state of flow B, that is, on the right side of the left end guide, it is the same as before, and in the state of flow A, on the left side, the -th printing position is enlarged L1 = 6.351111. L2=19.0511
If the setting is set to 111, it will be possible to handle both cases.

In addition, the dimension L1. It goes without saying that Lx can be changed by initial setting.

〔Effect of the invention〕

According to the present invention, a plurality of settings can be made by combining the switch settings and the position of the left end guide, which is effective in expanding specifications and improving usability.
