Further, the operating section C is provided with a manual cut button 17 and a display section 18, and the display section 18 is configured to display various information such as operating procedures, error displays, transmission/reception displays, etc.

Next, the operation of the apparatus configured as described above will be explained.

First, when setting the sheet roll, first set the hook 3.
The second housing B is released by releasing the lock, and a sheet roll 4a of A4 size, for example, is stored in the first holder 6, and the leading edge of the sheet is passed between the pair of feed rollers 11, and the leading edge of the sheet guide 12 is Bring it to the vicinity. Similarly, a B4 size sheet roll 5a, for example, is stored in the second holder 7.

The leading edge of the sheet is passed between the pair of feed rollers 14 and brought to the vicinity of the leading edge of the sheet guide 15.

After setting the sheet as described above, when the second housing B is closed, a message prompting manual cutting is displayed on the display section 18, and when the manual cutting button 17 is operated according to the display, the manual cutting operation is started.

To explain this operation, first, the feed roller pair 11 and the platen roller 8a rotate in the direction of the arrow shown in FIG. do. Furthermore, the cut recording sheet 4 is ejected from the apparatus, and the platen roller 8a and feed roller pair 11 are rotated in the opposite direction to the above, and the leading edge of the recording sheet 4 is rewound to near the leading edge of the sheet guide 12, and the recording sheet 4 is placed in a standby state. do.

After the operation of the recording sheet 4 is completed, the leading edge of the recording sheet 5 is cut by automatically operating the feed roller pair 14, the platen roller 8a, and the cutter 9 in the same manner as described above. The leading edge of the next recording sheet is rewound to the vicinity of the leading edge of the sheet guide 15 and placed in a standby state.

In order to perform the above operation, each roller drive motor 8e,
The drive motor 9d of llb, 14b and car, yue is the fifth
It operates at the timing shown in the figure. That is, the platen roller drive motor 8e and the feed roller drive motor llb start rotating at the same time, and when the recording sheet 4 has been conveyed by a predetermined amount, the drive motors 8e and llb are stopped, and then the cutter drive motor 9d is rotated. Then, the cutter 9 is operated to cut the recording sheet 4. When the cutting is completed, the cutter drive motor 9d stops rotating, and the drive motors 8e and llb are simultaneously rotated in the opposite direction to the above, thereby rewinding the leading edge of the recording sheet 4 to a predetermined standby position. At this point, the drive motors 8e, ll
By stopping the rotation of b, the cutting operation on the recording sheet 4 is completed. Subsequently, the cutting operation is performed on the recording sheet 5 by operating the drive motors 8e, 14b, and 9d in the same manner as described above, and the series of manual cutting operations is completed.

Here, when conveying the recording sheet 4.5 in the ejection direction,
Although the platen roller 8a and the feed roller pair 11.14 have begun to rotate simultaneously, the platen roller 8a is kept stopped while the leading edge of the recording sheet is conveyed from the standby position to the recording section by the feed roller pair 11.14. Similarly, when the leading edge of the recording sheet is rewound to the standby position after cutting the recording sheet, the platen roller 8a may be stopped when the leading edge of the recording sheet passes through the recording section.

The manual cutting operation cleans the leading edge of the recording sheet 4.5, and by controlling the amount of rotation of the platen roller 8a and the pair of feed rollers 11.14, the leading edge of the recording sheet is brought to an accurate standby position.

Next, when recording, it will be explained with reference to the flowchart shown in FIG. 6. If A4 size image information is received (SL), the width of the recording sheet 4 is determined by the sheet width detection sensor 13b to be A4 size. At the same time, the drive motor 11b is driven to rotate the feed roller pair 11 in the direction of the arrow in FIG. 3 (forward rotation) L, (S2).
, conveys the recording sheet 4 to the recording section 8. At the same time, the drive motor 8e is driven and the platen roller 8a is rotated in the direction of the arrow in FIG.

The recording sheet 4 is conveyed at a constant speed by a platen roller 8a, and a recording head 8b generates heat according to image information.
The received image information is recorded (S3).

When the recording of the image information received as described above is completed (
S4), the recording sheet 4 is conveyed by the platen roller 8a until the rear edge position of the image reaches the cutter 9, and the sheet is cut SS),
The recorded recording sheet is discharged out of the apparatus by the discharge roller pair 10 (S6), and the platen roller 8a and feed roller 11 rotate in the direction opposite to the arrow in FIG. is rewound to the standby position (S7), and recording of the A4 size received image is completed (S7).
a).

In the above process, each device is driven separately in the present invention, so when the platen roller and the feed roller pair are driven by one drive motor as in the conventional case, or similarly, the platen roller and the feed roller pair are driven by one drive motor. Unlike when driving a cutter, there is no need to use a solenoid or the like to change the direction of drive transmission, or to install a complicated gear train, so rotational errors such as backlash are extremely reduced. The conveyance amount can be accurately controlled.

Note that when the above-mentioned received image is B4 size, the sheet width detection sensor L6b detects that the recording sheet 5 is B4 size. operates in the same manner as described above to perform B4 size recording on the recording sheet 5 (812-317).

In addition, in the above-mentioned embodiment, a message was displayed using the display section provided on the operation section as a means to prompt the operator to perform manual cutting, but a lighting means such as an LED was provided at a predetermined location on the housing, and a message was displayed to prompt the operator to perform manual cutting. It may be configured to continue lighting until the end of the period.
