Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutter control method for a recording apparatus that performs recording while cutting continuous recording paper into a predetermined size with a cutter, and particularly to a case where the cutter is manually operated. And a cutter control method for the recording apparatus.

2. Description of the Related Art In printers and plotters that use continuous recording paper such as roll paper, the recording paper is cut into a predetermined size by a cutter and then discharged.
During normal recording operation, the paper is automatically cut by the cutter.However, if you want to set a new paper and align its leading edge, take out the paper when paper jam occurs, or use a special size paper When it is desired to cut the paper, it is necessary to manually cut the paper by key input on the operation panel.

[Problems to be Solved by the Invention] However, when manual cutting by key input is permitted, a part that should not be cut or a part that does not need to be cut is erroneously cut due to an erroneous operation of the operation panel, and paper is cut. There is a problem of wasteful consumption. Therefore, it is conceivable to operate the cutter only when the manual cut key is pressed at the same time as other keys. However, in this case, the number of keys increases and the key operation becomes complicated.

The present invention has been made in view of such a problem, and it is possible to extremely easily perform a manual cut by one key operation, and to prevent wasteful use of paper due to an erroneous operation. An object of the present invention is to provide a cutter control method for a recording apparatus.

[Means for Solving the Problems] A cutter control method for a recording apparatus according to the present invention is a cutter control method for a recording apparatus in which continuous recording paper is cut into a predetermined size by a cutter and discharged, and a manual cut key is pressed. When the recording device is in a paper jam state, it is determined whether the recording apparatus is in a paper jam state.
The cutter is operated only when the manual cut key is pressed again to cut the continuous recording paper.

[Operation] According to the present invention, when the manual cut key is pressed, the cut is not immediately activated, but first, it is determined whether or not the recording apparatus is in a paper jam state. In the case of a paper jam, there is no problem if cutting is performed immediately. Rather, it is desirable to perform cutting in order to remove the paper in the jammed portion. However, when the paper is not jammed, if the manual key is pressed by an erroneous operation, a part that should not be cut or a part that does not need to be cut may be cut by mistake. Therefore, in the present invention, when the paper is not jammed, the cutter is operated only when the manual cut key is pressed again to cut the paper.

Therefore, according to the present invention, although only one manual cut key is required and the operation is simple, erroneous operation can be prevented, and waste of paper can be minimized.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic side view showing a schematic configuration of an LED plotter to which the paper feeding method of the present invention is applied.

This LED plotter is composed of a plotter main body 1 and a roll paper storage section 2.

The roll paper storage unit 2 stores roll paper 22 formed by winding the continuous recording paper 21 in a roll shape.

The plotter body 1 includes a photosensitive drum 3. Around the photosensitive drum 3, a main charger 4, an LED head 5, a developing machine 6, a transfer charger 7, and a peeling charger 8 are arranged in this order from the upstream side in the rotation direction indicated by the arrow in the figure. The continuous recording paper 21 conveyed from the roll paper storage unit 2 to the inside of the plotter body 1 includes a paper feed clutch 11, a conveyance roller 12, a cutter 13, a conveyance roller 14,
Printing is performed via the transfer charger 7, the peeling charger 8, the transport roller 15, and the fixing device 16, and the print is discharged. Also, the cutter 13 is activated when a required size is sent in the printing process, cuts the continuous recording paper 21 and controls when the manual cut key 23 provided on the operation panel is pressed. It is operated under the control of the circuit 24. Sensors 17, 18, 19 for detecting the leading edge of the paper and for detecting the paper jam are provided downstream of the paper feed clutch 11, upstream of the transfer charger 7, and upstream and downstream of the fixing device 13, respectively. , 20 are provided.

Next, the manual cutting operation of the LED plotter according to the present embodiment configured as described above will be described.

FIG. 2 is a flowchart showing the sheet cutting operation of the control circuit 24 when the manual cut key 23 is pressed.

When the manual cut key 23 is pressed, first, it is determined whether the current situation is a paper jam state (S ₁ ). If in the case of a paper jam state based on the output of the sensor 17 to 20, the position of the paper jam is determined or after the front side of the cutter 13 (S _2), if, is later than the cutter position if, to cut the continuous recording paper 21 by operating the cutter 13 (S _3).
As a result, it is possible to easily remove the jammed portion and to align the leading ends of the sheets.

Further, when the position of the paper jam is short of the position of the cutter 13, by displaying that there is no paper at that position (S _4), the process ends.

On the other hand, when the manual setting key 23 is pressed, if not a paper jam state, to prevent cutting by erroneous operation, to determine whether align the leading edge of the sheet to the user (S _5). Here, if the user presses again the manual cutting key 23 in response to the message (S _6), first, a small amount from the feed at which no trouble recording paper to the discharge (S ₇₎ , and cuts the recording paper, indicating that is being cut (S _8). Then, to retrieve the cut sheets, performs sheet discharging send the paper to the discharge unit, and displays the meantime, is in the paper discharge (S _9).

With the above operation, one manual cut key 23
Thus, the leading edge of the paper 21 can be easily aligned, and malfunction can be prevented, and waste of the paper 21 can be minimized.

[Effects of the Invention] As described above, according to the present invention, even if the manual cut key is pressed, it is determined whether or not a paper jam has occurred without first operating the cutter, and determining whether the paper jam has occurred. When not in the state, the cutter is operated only when the manual cut key is pressed again to cut the paper, so that only one manual cut key is required, and the operation is simple and prevents erroneous operation. Paper use can be minimized.
