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

First, when setting the sheet roll, the hook 3 is unlocked to open the second casing B, the A4 size sheet roll 4a, for example, is stored in the first holder 6, and the leading end of the sheet is paired with the feed roller pair. Pass it through 11 and reach near the tip of the sheet guide 12. Similarly, for example, a B4 size sheet roll 5a is housed in the second holder 7, and the leading end of the sheet is passed between the pair of feed rollers 14 to reach the vicinity of the leading end of the sheet guide 15.

After setting the sheet roll as described above, the second housing B
Close and perform a manual cut operation.

This operation starts with the feed roller 11 and the platen roller.
The recording sheet 4 is conveyed to the cutter 9 and the discharge roller pair 10 by rotating 8a in the direction of the arrow shown in FIG. 3, and the tip of the recording sheet is cut by the cutter 9. Further, the cut recording sheet 4 is discharged to the outside of the apparatus, and the platen roller 8a and the feed roller 11 are rotated in the opposite direction to rewind the leading end of the recording sheet 4 to the vicinity of the leading end of the sheet guide 12 to be in a standby state. . Next, for the recording sheet 5, the feed roller 14, the platen roller 8a and the cutter 9 are operated in the same manner as described above to cut the leading edge of the recording sheet 5 and the cut sheet leading edge is cut into the sheet guide 15.
Rewind to the vicinity of the tip of and set to the standby state.

By the above manual cutting operation, the leading ends of the recording sheets 4 and 5 are cleaned, and by controlling the rotation amounts of the platen roller 8a and the feed rollers 11 and 14, the leading ends of the recording sheets are brought to an accurate standby position.

Next, at the time of recording, if image information of A4 size is received, the sheet width detection sensor 13b detects that the width of the recording sheet 4 is A4 size, and the feed roller 11 moves in the direction of the arrow in FIG. Then, the recording sheet 4 is conveyed to the recording unit 8. When the leading edge of the recording sheet 4 is conveyed to the pressure contact portion between the platen roller 8a and the recording head 8b, the driving of the feed roller 11 is stopped and at the same time the platen roller 8a rotates in the direction of the arrow in FIG. Is transported at a constant speed. In synchronization with this conveyance, the recording head 8b generates heat in accordance with the image information, and the heat generation records the received image information on the recording sheet 4. At this time, the feed roller 11 rotates around as the recording sheet 4 is conveyed.

When the recording of the image information received as described above is completed,
The recording sheet 4 is conveyed and cut until the trailing edge of the image reaches the cutter 9, and the recorded recording sheet is discharged from the discharge roller pair.
At 10 the sheet is discharged out of the apparatus, and the platen roller 8a and the feed roller 11 rotate in the direction opposite to the arrow in FIG. 3 to rewind the leading edge of the recording sheet 4 to the standby position.

Recording of the A4 size received image is completed as described above.
If the received image is of B4 size, the sheet width detection sensor 16b detects that the recording sheet 5 is of B4 size, and the feed roller 14,
The recording unit 8 and the cutter 9 operate in the same manner as described above to perform B4 size recording on the recording sheet 5.

Next, in jam processing or the like, the hook 3 is released from the lock and the second housing B is opened. At this time, since the respective feed roller pairs 11 and 14 are separately provided in the first casing A and the second casing B, the recording sheet 4 is provided on the first casing A side as shown in FIG. The recording sheet 5 is divided into the second housing B side. Therefore, when jamming one recording sheet or the like, the other recording sheet does not get in the way, and the sheet rolls 4a and 5a can be individually replaced. Further, when the second housing B is opened, the respective sheet rolls 4a and 5a can be seen at the same time, so that it is possible to easily confirm the remaining amount of rolls.

Also when setting the sheet roll, the platen roller 8a and the recording head 8b of the recording unit 8 are separately provided in the first casing A and the second casing B, and the cutter 9 is provided on the first casing A side. As shown in FIG. 4, for example, the leading end of the recording sheet 4 to be set is passed between the feed roller pair 11 and the gap between the cutters 9 and the discharge roller pair 10 along the platen roller 8a. It is possible to set the recording sheet 4 easily and surely by guiding to, and it is possible to easily prevent the recording sheet 4 from being obliquely set at the time of setting.
The same applies when the platen roller 8a of the recording unit 8 is provided in the second housing B and the recording head 8b is provided in the first housing A.

Further, by providing a drive system such as the feed roller pairs 11 and 14 and the platen roller 8a in the first housing A, the space can be effectively used and the weight of the second housing B can be reduced, so that the entire apparatus is small. It will be.

When the recording sheet 4 is set or jammed, as shown in FIG. 5, one drive roller 11a of the feed roller pair that conveys the recording sheet 4 is attached to the first casing A.
A pressure roller 11b provided on the side of the second housing B, which is in pressure contact with the roller.
With the configuration provided on the side, the recording sheet 4 is in a free state when the second housing B is opened, which facilitates setting and jam processing. In this case, it is effective to set a frequently used recording sheet in the first holder 6.

Further, in the above-mentioned embodiment, when the holders 6 and 7 store the sheet rolls of the same size, either one of the recording sheets, for example, the recording sheet 4 is used for recording. When the recording sheet 4 is used up, the sheet presence sensor 13a detects this and the control section can use the other recording sheet 5. In this case, the recording sheet 5 has a function as a spare.

Further, in the above-described embodiment, the sheet holders are provided on the first housing A side by side in the left and right, but they may be provided side by side in the vertical direction.

Further, in the above-described embodiment, the platen and the feed member are each constituted by a roller, but as another example, a rotary belt suspended by a pulley or the like may be used.

<Effects of the Invention> As described above, the present invention is configured such that the first housing and the second housing can be opened and closed, and two sheet rolls can be housed in the first housing to convey respective sheets. Since the feed member, the platen, and the recording head are separately provided in the both housings, it is possible to select and record a recording sheet suitable for the received image size, and also to easily set the recording sheet and perform jam processing. Moreover, since the two sheet rolls can be seen when the case is opened, the remaining amount of the roll can be confirmed at one time. Furthermore, if one sheet roll is used as a spare, it is possible to prevent reception failure due to the loss of recording sheets.
