Abstract

PURPOSE:To eliminate the need for a panel switching operation by setting a time lag (time difference) between the detection of paper and the drive of a suction roller. CONSTITUTION:A paper detection sensor 14 is provided for detecting paper 10 when the paper 10 is manually inserted to a printer from an insertion port 11. When a predetermined time elapses after the paper sensor 14 detects the paper 10, a suction roller 13 starts driving for feeding the paper 10 to a printing position. In this manner, a time lag (time difference) is provided between the detection of the paper 10 and the drive of the suction roller 13. Therefore, when an operator becomes aware of a paper set error or other errors immediately after setting the paper 10, the operator can pull back the paper and reset it. An improper operation caused by a paper setting error by an operator is prevented, an operation error is reduced, and the need for a panel switching operation is eliminated.

Description

[Detailed Description of the Invention] [Summary] Regarding the automatic paper insertion mechanism in a horizontal printer capable of printing on single sheets or bile sheets, when manually inserting sheets or using bile sheets such as slips,
The purpose is to provide a mechanism that can automatically insert paper without operating a switch on the panel, and when paper is manually inserted into the printer's insertion slot, it includes a detection sensor that detects the paper, and a detection sensor that detects the paper. The automatic paper insertion mechanism for a horizontal printer is characterized in that when a predetermined time has elapsed after detection, the drive of a suction roller is started to send the paper to a printing position.

[Industrial application field]

The present invention relates to a horizontal printer, and more particularly to an automatic paper insertion mechanism for a horizontal printer that can use both single-sheet and double-sheet paper.

In a horizontal printer, bifed paper such as copy paper, in which two or more sheets are stacked together to make one set, cannot be fed one set at a time to the printing unit by an automatic paper feeder such as a cut seed feeder. Therefore, such bile sheets are manually fed into the printer. Therefore, when these bile sheets or cut sheets are fed manually, it is desired that they be handled easily and easily.

[Conventional technology]

In conventional horizontal printers, in the case of single-sheet paper, the paper is manually set one by one into the printer's paper insertion slot, and the operator presses a switch on the operator panel to drive the suction roller to load the paper into the predetermined position. Either the seed was fed to the printing position or the cut seed feeder was used to automatically suction the seed. In the case of biplane paper, as mentioned above, the cut seed feeder cannot be used, so each set of paper is manually set in the paper insertion slot, and the operator presses a switch on the panel to inhale the paper.

[Problem to be solved by the invention]

When processing slips, it is convenient to use photocopiable bile paper, and such bile paper has been widely used in recent years, but when printing bile paper on a general-purpose printer, a cut seed feeder is used as described above. Since this cannot be done, it must be handled manually, and there is the inconvenience of having to press a switch on the panel when manually operating it.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a mechanism that allows manual insertion of single sheets and automatic insertion of multi-leaf sheets such as slips without operating switches on the panel.

[Means to solve the problem]

In order to solve such problems, according to the present invention, in a horizontal printer capable of printing on single-sheet paper or double-page paper, as shown in FIG. When a predetermined time has elapsed since ■ a paper detection sensor that detects the paper, and ■ a core paper sensor detects the paper, ■ the drive of the suction roller is started to send the paper to the printing position. An automatic paper insertion mechanism for a horizontal printer is provided.

[For production]

In the present invention, when paper is manually inserted and inhaled,
First, when paper is set, it is detected by the paper sensor. When detected, the suction roller is driven after a predetermined period of time has elapsed, and the paper is sucked. In this way, there is a time lag between detecting the paper and driving the suction roller, so if the operator notices an error such as a setting mistake immediately after setting the paper, he or she can pull the paper back and set it again. This eliminates the need for panel switch operations.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a schematic diagram of an embodiment of the automatic paper insertion mechanism for a horizontal printer according to the present invention. In Fig. 2, 10 is double-page paper such as a single sheet or a set of two or more sheets stacked together, 1 is a paper insertion slot, 12 is an insertion guide, 13 is a suction roller, 14 is a paper sensor, 15
1 is a print head, 16 is a platen, 17 is a discharge roller, 1
8 is a discharge guide. Paper 10 is for an operator (not shown)
When it is manually inserted into the insertion port 11 in the horizontal direction,
While being guided by the insertion guide 12, its tip hits the gap between the pair of suction rollers 13. A paper sensor 14, such as an optical sensor, is provided just before the suction roller 13, and detects that the leading edge of the paper 10 is set in a predetermined insertion slot 11.

When the paper sensor 14 continues to detect the presence of the paper 10 and a predetermined period of time has elapsed, the suction roller 13 starts to be driven, and the paper IO is fed by a predetermined amount, so that so-called cueing is performed. That is, the paper 10 is fed by the suction roller 13 to a predetermined printing start position. After printing, the paper passes through a pair of ejection rollers 17
The paper is discharged along the discharge guide 18 to a stacker (not shown).

Immediately after setting the paper 10, that is, before the paper sensor 14 detects the presence of the paper 10 and a predetermined period of time has elapsed, for example, if you notice a setting error such as tilting or misalignment of the paper 10, move the paper 10 directly to the paper guide. Just pull it back from 12 and set it again.

In this way, even if the paper sensor 14 detects the paper 10 once, the suction roller 13 will not be driven unless it continues to detect the paper 10 for a predetermined period of time. After a predetermined period of time has elapsed, it is assumed that the paper 10 is properly set, and the paper 10 is located at the beginning.

〔Effect of the invention〕

As explained above, according to the present invention, there is a time lag (time difference) between the detection of paper and the drive of the suction roller, so that the operator can avoid errors such as setting errors immediately after setting the paper. If you notice it, you can pull back the paper and set it again, preventing improper operation due to operator's setting mistake and reducing operational errors. Furthermore, since it is not necessary to operate a switch on the panel, handling of media in the horizontal printer device becomes easier, which greatly contributes to improved operability.
