[0003]

The above prior art has the following problems 1-3. 1. After the recording paper is set, if the operator opens the plotter cover again to check the state of the recording paper (roll paper), the recording paper is removed from the setting state, and it is necessary to set the recording paper again. 2. When setting the recording paper, the operator pulls out the recording paper much longer than the cutter mechanism, and if the recording paper is cut in this state, the margin becomes long and the recording paper is wasted. 3. After the recording paper is set, the facsimile apparatus returns to the initial state (standby state), but does not perform any display before returning to the initial state, so that it is difficult for the operator to immediately recognize the state of the apparatus. SUMMARY OF THE INVENTION It is an object of the present invention to provide a recording paper conveyance control method for a recording apparatus which is suitable for improving the operability and eliminating waste of paper by improving such problems.

[0004]

In order to achieve the above object, a recording sheet conveyance control method for a recording apparatus according to the present invention comprises a cutter mechanism for cutting a roll-shaped recording sheet, and a cutter mechanism arranged upstream of the cutter mechanism. Recording mechanism, a mechanism for transporting recording paper, and the presence or absence (ON) of recording paper between the recording mechanism and the cutter mechanism.
/ OFF) sensor, the sensor once detects the OF in a newly set recording sheet.
A first step of pulling back until F (paper out detection);
Thereafter, a second step of transporting the recording paper to the cutter mechanism and cutting the recording paper by a predetermined length, and thereafter, a third step of pulling the recording paper back until the sensor is turned off (paper out detection) is performed again.
And a fourth step of transporting the recording paper to a predetermined standby position and waiting for the input of a print start command thereafter. When a print start command is input after the fourth step, the recording paper is pulled back from the standby position to a print start position (a position where the recording paper is pulled back by a certain length after the sensor detects the absence of paper). The standby position is set closer to the cutter mechanism than the print start position. Further, the recording apparatus includes an operation panel having means for displaying characters, in this operation panel,
In the fourth step, before recording paper is conveyed to the standby position, "recording paper setting completed" is displayed.

[0005]

In the present invention, when the recording paper is set, the recording paper is once pulled back and then sent out to the cutter mechanism side for a fixed length.
Since the cut and does not cut the recording sheet more than necessary. In addition, by setting the recording paper setting position in the standby state near the cutter (close to the discharge port), the recording paper is prevented from deviating from the printing start position when the cover is opened and closed.

[0006]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a flowchart showing a recording paper conveyance control method according to an embodiment of the present invention, and FIG. 5 is a diagram showing, in chronological order, a state from setting of a recording paper to immediately before printing in an embodiment of the present invention. FIG. 2 shows a facsimile apparatus according to this embodiment.
In addition to the apparatus shown in FIG. 3, a display capable of displaying characters (for example, a liquid crystal display) is provided on the operation panel, and a function of displaying presence / absence of paper and operation guidance at the time of paper setting is provided on this display ( Function of a system control unit including a CPU and the like).

In this embodiment, as shown in FIG. 1, when the S1 sensor detects the end of the recording paper 101), the display of "no recording paper" is performed (102). With this display, the operator replaces the recording paper (roll paper) with a new one in accordance with guidance such as an instruction manual. The state when the recording paper is set is shown in FIG. When the recording paper is set in this way, the S1 sensor is turned on (103). Next, a door sensor (not shown) is monitored, and after detecting that the plotter cover is not open (104), the platen roller 29 is reversed (106). At this time, the S2 sensor is ON. Further, when it is detected that the S2 sensor is turned off (107), the reverse rotation of the platen roller 29 is stopped. The state when the recording paper is pulled back is shown in (2) of FIG. If the door sensor is OFF in step 104, a message "Please close the cover" is displayed (105). Next, in order to send out the recording paper, the platen roller 29 is normally rotated for a predetermined time (1).
08) After the recording paper of a fixed length is discharged, the cutter mechanism 33 is driven to cut the recording paper (109). This state is shown in FIG. Next, the platen roller is reversed (110) until the S2 sensor is turned off (111).
Pull back the recording paper. This state is shown in FIG. Thereafter, the platen roller is rotated forward for a predetermined time (11).
2) After entering the standby state, display "recording paper set completed" is displayed before entering the standby state (113). This operation is to confirm that the recording paper has not been jammed by the cutter. This standby state is shown in FIG.
(5). Next, when a print start command comes in a standby state (114) (115), the platen roller is rotated reversely (1).
16) After the S2 sensor is turned off, the recording paper is pulled back by a certain length. This condition as shown in (6) in FIG. 5
And the recording paper is pulled back to the position just before printing starts.
I have . Thereafter, the platen roller 29 is rotated forward (11).
7), a printing operation is started (118). Thereafter, after the printing is completed, the process returns to the cutter driving in step 109,
The process proceeds to step 114 in the standby state, but in this case, the display (113) of “recording paper set completed” is skipped.

In the prior art, when the recording paper is set, the recording paper is not pulled back, and the recording paper is set as shown in FIG. 5 (1) → (3) → (4).
Transitions. During normal operation (other than when recording paper is set)
Changes from (3) to (4) in FIG. 5, and in the standby state, the recording paper does not hit the S2 sensor. According to this embodiment, by stopping the leading end of the recording paper at a position closer to the discharge port than the position in the related art, the recording paper does not come off the set position by opening and closing operations of the plotter cover and the like.

[0009]

According to the present invention, it is possible to save a margin when setting the recording paper, and it is not necessary for the operator to reset the recording paper even when the cover is opened and closed. Further, by displaying that the recording paper set is completed before returning to the standby state, the operator can be informed of the state of the apparatus.
