Abstract

PURPOSE:To facilitate an adjustment in a printer by providing: a printing paper selecting means, a minute-adjusting means performing a minute adjustment of a fed printing paper position: one or more minute adjustment amount memory means selected by the printing paper selecting means: and one or more paper feeding means feeding a paper to a position being adjusted in accordance with the instruction commanded by the minute adjustment memory means. CONSTITUTION:Each of printing papers selected by a printing paper selecting means 1 is moved by respective paper feeding means 4 or 5 and after being fed, each paper position is corrected by a minute-adjusting means 6 and is made to correspond to each paper, and more than one minute adjustment amount memory means 2 are stored in one of the means 3. When further paper feeding means 4 or 5 is actuated, while a stored content corresponding to a paper of one or more minute amount adjustment amount memory means 2 or 3 is read out, and the paper feeding means 4 or 5 moves the paper to a position previously adjusted in accordance with its content. In other words, only one time adjustment is sufficient enough as to each printing paper, and thereafter an optimum printing position is made available regardless of the differences in environment and mechanisms of printers.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a paper feeding device for a printer.

[Conventional technology]

Printers use paper of various types, thicknesses, hardnesses, and sizes, and also have an I/O system for fixing and moving the paper.
! Especially when the mechanism uses friction with the paper, it is difficult to accurately feed the paper to the desired position, especially when feeding the paper.

Furthermore, depending on how the paper is used, it may be necessary to align the printing position with the ruled lines of the form, and even if a certain paper feeding position is repeated, readjustment may be required each time.

[Problem that the invention seeks to solve]

Conventionally, in such cases, the user rotated the knob by hand to adjust the position after feeding the paper. In addition, if the paper position after paper feeding is known in advance, a method is used in which the host computer/computer commands a small amount of paper feed before printing starts, but in this case too, the temperature However, it is not always possible to achieve a constant paper position after paper feeding due to changes in environmental conditions such as humidity, paper thickness, or the accuracy of the original paper feeding mechanism, so some kind of adjustment must be made repeatedly. There was a problem.

The present invention has been developed in view of these problems, and its purpose is to make one adjustment depending on the type of paper and individual differences in environmental conditions, so that the optimal paper feeding position can be found from then on. It is about providing.

[Means for solving problems]

In the printer of the present invention, the paper selection means and the paper feeding position are
moving the paper to a paper feeding position adjusted according to the contents of the fine adjustment means, one or more fine adjustment amount 213 means selected by the paper selection means, and the fine adjustment intervention means; It is characterized by having three or more paper feeding means.

[Effect]

According to the above configuration of the present invention, the paper selected by the paper selection means is moved by the paper feeding means for each paper, and the paper position after feeding is corrected by the fine adjustment means, and a plurality of sheets are adjusted corresponding to each paper. It is stored in one of the fine adjustment amount storage means.

When the paper feeding operation is performed again, the paper feeding means selected by the paper selection means operates, and one memory content corresponding to the paper of the plurality of fine adjustment amount storage means is read out.
The paper feed method depends on the content.

The paper is then moved to the previously adjusted position.

〔Example〕

FIG. 1(a) shows the configuration of one embodiment of the present invention. In this case paper! ! The paper feeding means 1 is operated by a switch 7 on the operating computer panel or an output 13 obtained by the printer control means 9 decoding a command obtained from the host computer/computer (not shown) through the interface means 10, and the paper feeding means 4 or 5 to be operated. Fine adjustment amount storage means 2
Or select 3. When the paper feeding operation is started by the printer control means 9, the selected paper feeding means 4 obtains the previously adjusted adjustment amount from the selected fine adjustment amount storage means 2 and moves the paper to the same position. . Thereafter, the fine adjustment means 6 becomes operational and the switch 8 on the operation panel
The fine adjustment amount is stored in the selected fine adjustment amount storage means 2 at the same time as the paper is moved in accordance with the operation of the paper selection means 1, and is prepared next when that paper is selected by the paper selection means 1.

In the case of this embodiment, the paper is assumed to be type 2!1, and paper feeding means 4.5 and fine adjustment amount storage means 2.3 are provided for single sheets and continuous paper (forms), respectively. .

FIG. 2(a) shows the configuration of one of the embodiments of the present invention. In this embodiment, there are two cut sheet holding means 20.
a, 20b and the operation panel 14,
Since postcards can be selected, seven types of paper are assumed, and seven fine adjustment amounts 213 means 100. . . , 400 and four paper feeding means 5° to 503 are provided. Seven papers and paper feeding means 500 selected by paper selection means 1
~5°3 and fine adjustment amount storage means 100. ..., 400 relationships are as shown in Table 1. In this embodiment, not only the number of paper feeding means is increased compared to the case of FIG.
We are considering the case of being hit by 3. The print start position can be actively adjusted no matter how thick, hard paper like postcards are used.

1(b) and 1(a); FIG. That is, in step (A), first,
Execute the paper feeding operation according to the paper type and proceed to step (B).
), the paper feed is finely adjusted, and in step (C), the amount of fine adjustment is stored in a storage means provided for each type of paper.

FIG. 2(b) is a flowchart of the operation of the embodiment of FIG. 2(a). The basic operation is the same as that in FIG. 1(b), but in the example of FIG. 2, since there are two C8Fs, an operation to determine which one of them is included is included.

Table 1 [Effects of the Invention] As described above, according to the present invention, the optimum paper feeding position can be adjusted and stored according to a plurality of Eltm papers.
By making this adjustment, an arbitrary optimal printing position can be provided for each sheet of paper, regardless of individual differences in the environment or the mechanism of the printer.
