Therefore, when only the second housing B rotates, the sensor 19b turns OFF and detects this, and when the second housing B and the intermediate member C rotate together, both sensors 19a and 19b turn OFF. It is now possible to detect this.

In addition, in FIG. 2, 22 is a document transport system, which is connected to the second housing B.
The original 23 placed on the original placing table 22a formed on the upper surface and guided on both sides by the original side guides 22b is separated one by one by the separating roller 22c, and is fixed to the left side of the drawing by the conveying roller 22d. The paper is conveyed at a high speed and is discharged onto a discharge tray 22f by a discharge roller 22e.

Also, while the original 23 is being conveyed, the original reading system 24
Light is emitted from a light source 24a, and the reflected light passes through a plurality of mirrors 24b and lenses 24c to an image reading element 24d such as a CCD, where the image of the original 23 is read, and the image signal is sent to a predetermined recording system. configured to be transmitted.

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

First, in setting the sheet rolls 2a and 3a, the lock members 17a and 17b are both unlocked to release the second housing B and the intermediate member C from the first housing A, and the first holder 4 is, for example, An A4 size sheet roll 2a 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 in the recording section 6 than the feed roller lla.
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 feed roller pair 9a, 9b and the platen roller 6a rotate 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, llb, 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 transferred to the recording section from 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 image trailing edge position reaches the cutter 7 position, is cut, and the recorded recording sheet is ejected to the cutter 7 position.
a, 8b to eject it out of the device, and the platen roller 6
a and the pair of feed rollers 9a and 9b are rotated in the direction opposite to the arrow in FIG. 2 to rewind the leading edge of the recording sheet 2 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.

If the color of the recording sheet 2.3 is, for example, white, there is a black band near the end (about one end of the end) and irradiated by the sheet presence/absence detection sensors 15a and 16a, which has a different light reflectance from white. Put it in. Therefore, the sensor 15a
If +16a detects white, the sheet is
If black is detected, the sheet is "absent". When the sensor 15a detects the sheet r/j, the sensor 15a
When the LED of the locking member 17a blinks in response to the signal from 5a and the sensor 16a detects "No seat r",
Similarly, the LED of the lock member 17b blinks.

For example, if the LED of the lock member 17a is blinking, when the lock member 17a is unlocked and the device is opened, the lock member 17b remains in the locked state, so as shown in FIG. 1 (^) (B). 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, and remains gripped by the detent torque of the motor 13a, 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 not 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, since these sensors can detect that the sheet roll 2a 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, recording is performed according to the signal from the sensor 19a. The manual cutting operation described above is performed only on sheet 2, and initial settings are made.

Also, if the LED of the locking member 17b 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 is held between the pair of feed rollers 9a and 9b as shown in FIG. 3(B), and the motor 10 is
Since it remains gripped by the detent torque of a, the leading edge standby position of the recording sheet 2 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 then performed to make initial settings.

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

During recording, feed roller pair 9a, 9b or lla
, Ilb, platen roller 6a, etc. are driven by a pulse motor, and the number of pulses is counted and the leading edge of the recording sheet is conveyed by the number of pulses necessary to convey it from the recording section 6 to the position of the sheet detection sensor 18. Also, the sensor 18
If the recording sheet is not detected, 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. L of member 17b
Flashing ED.

Therefore, in the same way as when replacing the sheet roll, unlock the lock member whose LED is flashing and remove the second housing B.
Alternatively, the jam may be cleared by opening 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 lla and llb, 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.

Further, by providing the feed member and its drive source in the intermediate member, the driving force transmission system can be simplified, and the number of parts can be reduced, thereby reducing costs.
