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

First, in setting the sheet rolls 2a and 3a, both the lock members 17a and 17b are unlocked to release the second housing B and the intermediate member C from the first housing A, and at the same time, for example, an A4 A sheet roll 2a of the same size is accommodated, and the intermediate member C is closed so that the leading edge of the sheet is closer to the recording unit 6 than the feed roller 9a.
Lock the locking member 17a. Similarly, for example, a B4 size sheet roll 3a is stored in the second holder 5,
The leading edge of the sheet is located at the recording section 6 below the feed roller Ila.
Close the second casing B so that it approaches the lock member 1.
Lock 7b.

After setting the sheet roll as described above, a manual cutting operation is performed.

In the above operation, when the start switch 25 is turned on, the pair of feed rollers 9a, 9b and the platen roller 6a are rotated in the direction of the arrow in FIG. The leading edge of the recording sheet 2 was cut, and the cut recording sheet was discharged to the outside of the apparatus, and the leading edge of the recording sheet 2 was rewound to a predetermined position closer to the recording unit 6 than the sheet presence/absence detection sensor 15a, and placed in a standby state. Next, for the recording sheet 3, the feed roller pair 11a, 11b, the platen roller 6a, etc. are operated in the same manner to cut the leading edge of the recording sheet 3, and the leading edge of the cut sheet is detected by the sheet presence/absence detection sensor 16a. Rewind to a predetermined position near 6 and put it in standby mode.

By the manual cutting described above, the leading edge of the recording sheet 2.degree. 3 is trimmed and the leading edge of the sheet is brought to an accurate standby position.

Next, when recording, if an image signal of A4 size is received, the sheet width detection sensor 15b detects that the width of the recording sheet 2 is A4 size, and the feed roller pair 9a, 9b moves to the second Rotate in the direction of the arrow in the figure,
The recording sheet 2 is conveyed to the recording section 6. This record sheet 2
When the tip of the recording sheet 2 is conveyed to the pressure contact portion between the platen roller 6a and the recording head 6b, the drive of the feed roller 9b is stopped, and at the same time, the platen roller 6a rotates in the direction of the arrow in FIG. 2 to convey the recording sheet 2 at a constant speed. .

In synchronization with the above-mentioned conveyance, the recording head 6b generates heat in response to the image signal and records an image on the recording sheet 2. At this time, the feed roller pair 9a, 9b rotates as the recording sheet 2 is conveyed.

When the recording of the received image is completed as described above, the recording sheet 2 is conveyed until the trailing edge of the image reaches the cutter 7 position and cut, and the recorded recording sheet is ejected to the pair of rollers 8a.
, 8b to the outside of the apparatus, and the platen roller 6a.
Then, the feed roller pair 9a, 9b is rotated in the direction opposite to the arrow in FIG. 2, and the leading edge of the recording sheet 2 is rewound to the standby position.

If the received image is B4 size, the feed roller pair 11a, llb, platen roller 6a, etc. are driven to record on the recording sheet 3 in the same way as in the case described above.

Next, a case will be described in which either one of the recording sheets 2 and 3 is used up.゛Said recording sheets 2 and 3
For example, if the color is white, the area near the end (approximately 1 m
degree), and the sheet presence/absence detection sensors 15a, 16
A black band whose light reflectance is different from that of white is placed in the irradiated part a. Therefore, if the sensors 15a+16a detect white, it means that sheet "1" is present, and if they detect black, it means that sheet "r" is absent.
When detecting "No", the LED of the locking member 17a blinks according to the signal from the sensor 15a, and the sensor 16
When a detects the seat r and no j, the lock member 17
The LED b flashes.

For example, if the LED of the locking member 17a is flashing, when the locking member 17a is unlocked and the device is opened, the locking member 17b remains in the locked state. As shown in , the second casing B and the intermediate member C are released from the first casing A as a whole. Then, a new sheet roll 2a is loaded.

In addition, when loading the sheet roll 2a, as shown in FIG.
), the recording sheet 3 is fed by a pair of feed rollers 11a.
, llb, the leading edge standby position of the other recording sheet 3 is not affected when the sheet roll 2a is replaced.

Furthermore, when the second housing B and the intermediate member C are rotated together to replace the sheet roll 2a as described above, both the open detection sensors 19a and 19b turn OFF and detect this. Therefore, by these sensors, the sheet roll 2
Since it is possible to detect that a has been replaced, when the second casing B and the intermediate member C are closed and the start switch 25 is turned on after the replacement, only the recording sheet 2 is replaced in response to the signal from the sensor 19a. The manual cut operation described above is performed and initial settings are made.

Also, if the LED of the locking member L7b is blinking,
When the locking member 17b is unlocked to open the second casing B, the locking member 17a remains in the locked state, so the intermediate member C is closed to the first housing as shown in FIGS. 3(A) and 3(B). It is integrated with case A. Then, a new sheet roll 3a is loaded.

Also, when replacing the sheet roll 3a, the recording sheet 2 remains gripped by the pair of feed rollers 9a and 9b as shown in FIG. Position is not affected.

Furthermore, when only the second housing B is opened to replace the sheet roll 3a as described above, the opening detection sensor 19b is activated.
This is detected by the FF. Therefore, the sensor 19b
Since it is possible to detect that the sheet roll 3a has been replaced by The above-mentioned manual cut operation is performed only for 3, and the initial settings are made.

Next, a case where recording sheet 2 or 3 jams will be explained.

During recording, feed roller pair 9a, 9b or 11
a, 11b, the platen roller 6a, etc. are driven by a pulse motor, and the number of pulses is counted to convey the leading edge of the recording sheet from the recording unit 6 to the position of the sheet detection sensor 18 by the number of pulses required. However, if the sensor IB does not detect the recording sheet, it is determined that a jam has occurred. If a jam occurs while recording on the recording sheet 2, the LED of the locking member 17a blinks based on the signal from the sensor 18, and if a jam occurs while recording on the recording sheet 3, the lock is locked. The LED of member 17b is blinked.

Therefore, in the same way as when replacing the sheet roll, L E
The jam can be cleared by unlocking the lock member with flashing D and opening the second casing B or the intermediate member C. At this time as well, since the recording sheet that is not to be jammed is gripped by the pair of feed rollers 9a and 9b or Ila and Ilb, the leading edge position will not shift.

<Effects of the Invention> As described above, in the present invention, the two roll sheets set respectively have independent conveyance paths.

Therefore, when one of the recording sheets is replaced or a jam is cleared, even if the conveyance path of that sheet is opened, the conveyance path of the other recording sheet is not affected. Therefore, the user's operation is simplified.

Furthermore, if a member is provided to lock the first housing and the intermediate member, and the intermediate member and the second housing, respectively, and the member to be unlocked is notified when replacing the sheet roll or clearing a jam, the above-mentioned operation can be performed. can be done even more easily.
