However, if the operator forgets to perform a manual cut operation, the leading edge of the recording sheet often enters a standby state at a position other than the normal position, so there may be excess margins at the leading edge of the recorded and cut sheet. There have been problems such as problems such as the occurrence of a problem such as a loss of information on the recorded image at the leading edge or the like.

The present invention solves the above-mentioned conventional problems, allows two recording sheet rolls to be stored compactly, and also automatically cuts the leading edge of the recording sheet and allows the leading edge to wait at a regular position. The aim is to provide as many recording devices as possible.

The rollers are pressed against each other by e and 14e, and one roller is configured to rotate as a result of the rotation of the other roller.

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

First, when setting the sheet roll, use the Funk 3
Release the lock to release the second body B, and then remove the first holder 6.
A sheet roll 4a of A4 size, for example, is stored therein, and the leading edge of the sheet is passed between a pair of feed rollers 11 to reach near the leading edge of a sheet guide 12. Similarly, a sheet roll 5a of B4 size, for example, is stored in the second holder 7, and the leading end of the sheet is passed between the pair of feed rollers 14 and brought to the vicinity of the leading end of the sheet guide 15.

After setting the sheet rolls 4a and 5a as described above,
The second housing B is closed and the operation moves to cutting the leading end of the recording sheet 4.5. When the opening/closing detection sensor 17 detects that the second casing B is closed, the next operation is automatically performed.

First, the feed roller pair 11 and the platen roller 8a are rotated in the direction of the arrow shown in FIG. Further cut recording sheet 4
At the same time, the platen roller 8a and the pair of feed rollers 11 are rotated in the opposite direction to the above, and the leading edge of the recording sheet 4 is rewound to the vicinity of the leading edge of the sheet guide 12 to be in a standby state. Regarding the sheet 5, the leading edge of the recording sheet 5 is cut by operating the feed roller pair 14, the platen roller 8a, and the cutter 9 in the same manner as described above, and the leading edge of the recording sheet after being crimped is rewound to near the leading edge of the sheet guide 15. Put it on standby.

Here, when the second housing is closed, regardless of whether there is a recording sheet or not, it is possible to assume two recording sheets as described above and perform the cutting operation on each of them consecutively, but if the recording sheet is not attached If not, the cutting operation can be omitted as follows.

For example, if only one recording sheet is attached, there is no need to perform a cutting operation on the side that is not attached.
Therefore, as shown in the flowchart of FIG. 5, when it is detected that the second casing is closed, that is, when the open/close detection sensor is turned on, the sheet presence/absence sensor 13a continues.
The presence or absence of recording sheet 4 is confirmed by No driving operation is performed, and then the presence or absence of the recording sheet 5 is confirmed by the sheet presence/absence sensor 16a, and then the cutting operation is started.

The above operation is an example in which the cutting operation is performed continuously on two recording sheets 4°5, but for example, it is possible to finish the cutting operation by cutting only the leading edge of the replaced recording sheet 4 or 5. In this case, it is only necessary to have the replaced side perform the corresponding operation among the above operations.

Here, the determination as to which side of the recording sheet has been replaced is made by the opening/closing detection sensor 17 of the second housing B and the sheet presence/absence detection sensors 13a and 16a.

The leading edge of the recording sheet 4.5 is cleaned by the cart/cart operation, 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. 7. If A4 size image information is received, the sheet width detection sensor 13b detects that the width of the recording sheet 4 is A4 size. At the same time,
Drive motor 11b moves 1 section of force to feed roller pair 11
rotates in the direction of the arrow in Figure 3 (forward rotation), and the recording sheet 4
is conveyed to the recording section 8. At the same time, the drive motor 8
e is driven, and the platen roller 8a rotates in the direction of the arrow in FIG.

In this case, the recording sheet 4 is conveyed at a constant speed by a platen roller 8a, and the received image information is recorded by a recording pad 8b that generates heat according to the image information.

When the recording of the image information received as described above is completed, the recording sheet 4 is conveyed and cut by the platen roller 8a until the trailing edge position of the image reaches the cutter 9, and the recorded recording sheet is transferred to the discharge roller pair 10. At the same time as ejecting the recording sheet from the apparatus, the platen roller 8a and the feed roller 11 rotate in the direction opposite to the arrow shown in FIG. End recording.

In the above process, in the present invention, each device is driven separately, so unlike the conventional case where the platen roller and the feed roller pair are driven by two drive motors, or similarly, one drive motor is used to drive the platen roller and the feed roller pair. Unlike when driving a platen roller and cutter, there is no need to use a solenoid to change the direction of drive transmission, or to install a complicated gear train, so rotational errors such as backlash are extremely reduced, making recording easier. The amount of conveyance of the sheets 4 and 5 can be accurately controlled.

If the received 1g image is 84 size, the sheet width detection sensor 16b detects that the recording sheet 5 is B4 size, and the feed roller 14, the recording section 8 and the cutter 9 move against the recording sheet 5. It operates in the same manner as described above to perform B4 size recording on the recording sheet 5.

FIG. 8 is a block diagram of the surroundings of the control unit, which has already been described in detail in the specification of Japanese Patent Application No. 114705/1983. C0NT is the transmission data control unit, MO
DEM CONT is a demodulator control section, W-CONT is a recording control section, M-CONT is a motor control section, CPU is an arithmetic control section, ROM and RAM are memories, TPH is a thermal head, and THD is a thermal head driver.

<Effects of the Invention> The recording device according to the present invention has the structure and operation as described above. In particular, when the second housing is closed after replacing the recording sheet roll, the leading edge of the recording sheet is cut in conjunction with this. Since the positioning of the tip and tip is automatically performed,
There is no need for the operator to change the sheet roll manually.
In addition, there is no need to worry about forgetting the alignment of the cut and tip, making the operation extremely simple and ensuring reliable setting.
Furthermore, since the platen and each feed member can be freely controlled by individual drive sources, it is possible to feed the sheet l'lit with a high degree of freedom, and it has the effect of increasing the conveyance accuracy. It is.
