Further, while the original 18 is being conveyed, it is irradiated with light by a light source 23 of an original reading system, and the reflected light reaches an image reading element 26 such as a CCD through a plurality of mirrors 24 and lenses 25, and the reflected light reaches an image reading element 26 such as a CCD. The image is read and
The image signal is configured to be transmitted to a predetermined recording system.

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

First, when setting the sheet roll, use hook 3.
Release the lock to open the second casing 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 inserting the sheet roll as described above, the second housing B is closed and a manual cutting operation is performed.

In this operation, first, the feed roller pair 11 and the platen roller 8a are rotated in the direction of the arrow shown in FIG.
is conveyed to a cutter 9 and a pair of discharge rollers 10, and the cutter 9 cuts the leading edge of the recording sheet. Further, the canted recording sheet 4 is discharged out of the apparatus, and the platen roller 8a and the pair of feed rollers 11 are rotated in the opposite direction to the above, the leading edge of the recording sheet 4 is rewound to the vicinity of the leading edge of the sheet guide 12, and the recording sheet 4 is placed in a standby state. do. Next, the leading edge of the recording sheet 5 is cut by operating the feed roller pair 14, platen roller 8a, and cutter 9 in the same manner as described above, and the leading edge of the recording sheet after cutting is moved to near the leading edge of the sheet guide 15. Rewind and put into standby mode.

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 feed roller pair 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 and the block diagram shown in FIG.
The signal is demodulated by the ODEM (demodulator), becomes a digital signal, and is sent to the data controller. One of the recording sheets is selected according to the data. For example, when A4 size image information is received, the sheet width detection sensor 13b detects that the width of the recording sheet 4 is A4 size, and the motor 11b is driven by a signal from the CPU (central processing unit). As a result, the feed roller pair 11 is rotated (forward rotation) in the direction of the arrow in FIG. 3, and the recording sheet 4 is conveyed to the recording section 8.

At the same time, the drive motor 8e drives the platen roller 8a.
is rotated in the direction of the arrow in FIG. 3, and at this time, the peripheral speed of the feed roller pair 11 is made faster than the peripheral speed of the platen roller 8a, thereby causing the platen roller 8a and the recording head 8b, which are rotating the leading edge of the recording sheet 4, to rotate in the direction of the arrow in FIG. Forcibly feed it to the pressure contact part.

As described above, when the leading edge of the recording sheet 4 is conveyed to the recording section 8, the drive motor 11b is turned off, and the recording sheet 4 is conveyed at a constant speed by the platen roller 8a, and the recording head generates heat according to the image information. 8b records received image information. At this time, the feed roller pair 11 rotates as the recording sheet 4 is conveyed.

Note that the feed roller pair 11 and the platen roller 8a
The rotation control is performed by transmitting a signal from the CPU to the motors 11b and 8e, which rotate the respective rollers, via a motor control section and a motor driver.

Further, the data control section outputs data to the data bus and R
AM (Random Access Memory) captures this data. Further, the data in the RAM is taken into the CPU and decoded, and the decoded data is sent to the RAM again and stored. Furthermore, when one line of data is stored in the RAM, the data is sent to the recording control section, and further sent from the recording control section to the recording head 1 driver, where the recording driver 8b records one line of data.

When the recording for one line is completed, the motor 8e is driven by a signal from the CPU to rotate the platen roller 8a and print the recording sheet 4 one by one.
Convey by line. By repeating this, recording for one page is completed.

When the recording of the image information received as described above is completed, the recording sheet 4 is conveyed by the platen roller 8a until the trailing edge position of the image reaches the cutter 9, and the motor 9a is driven to operate the cutter 9 to perform the recording. The sheet 4 is canted, and the recorded recording sheet is discharged out of the apparatus by the discharge roller pair 10, and the platen roller 8a and the feed roller pair 1
1 rotates in the direction opposite to the arrow in FIG. 3 (reverse rotation), and the leading edge of the recording sheet 4 is rewound to the standby position to complete recording of the A4 size received image.

In addition, during the above-mentioned recording, whether the leading edge of the recording sheet 4 was conveyed to the recording unit 8, whether the trailing edge of the image was conveyed to the cutter position, and whether the leading edge of the recording sheet 4 was rewound to the standby position or not. This is detected by counting the number of rotation steps of the motor 11b that rotates the feed roller pair 11 and the motor 8e that rotates the platen roller 8a, and when the recording sheet 4 is conveyed to the predetermined position, the CPU It emits a signal to operate the

In the above process, the recording sheet 4 is transferred to the recording section 8 by the drive motor 11b that rotates the feed roller pair 11.
Since it is only necessary to apply current to drive the motor 11b when transporting the motor 11b to the standby position and when rewinding it to the standby position, power consumption can be saved and troubles such as overheating in the drive motor 11b can be prevented. I can do it. In addition, unlike the case where the platen roller and feed roller pair are driven by two drive motors, there is no need to change the direction of drive transmission using a solenoid or the like, or to provide a complicated gear train, so there is no need to use a complicated gear train, so bank lash, etc. Rotation errors are extremely reduced, and the amount of conveyance of the recording sheet 4 can be accurately controlled.

Note that when the received image is B4 size, the sheet width detection sensor 16b detects that the recording sheet 5 is B4 size, and the feed roller 14, recording unit 8, and cutter 9 It operates in the same manner as above to perform B4 size recording on the recording sheet 5.

Next, in handling a jam, etc., the hook 3 is unlocked and the second casing B is opened. At this time, since the feed roller pairs 11 and 14 are separately provided in the first housing A and the second housing B, the recording sheet 4 is
is separated into the first case A side, and the recording sheet 5 is separated into the second case B side. Therefore, when cleaning a jam on one recording sheet, the other recording sheet does not get in the way, and the sheet rolls 4a and 5a can be replaced individually. Furthermore, when the second housing B is opened, the respective sheet rolls 4a and 5a can be viewed at the same time.
It is possible to easily check the remaining roll amount.

Also, when setting the sheet roll, the platen roller 8a and recording head 8b of the recording section 8 are provided separately in the first housing A and the second housing B, and the cutter 9 is provided on the first housing A side. As shown in FIG. 4, for example, the leading edge of the recording sheet 4 to be set is passed between a pair of feed rollers 11, and
By passing the cutters 9 along the platen roller 8a and through the gap between the cutters 9 and between the pair of discharge rollers 10 and leading them out of the apparatus, it is possible to easily and reliably cent the recording sheet 4. Setting can also be easily prevented. The same applies to the case where the platen roller 8a of the recording section 8 is provided in the second casing B and the recording head 8b is provided in the first casing A.

Furthermore, the feed roller pair 11.14 and the platen roller 8a
By providing such a drive system in the first casing A, space can be used effectively, and the weight of the second casing B can be reduced, so that the entire device can be made smaller.

Incidentally, when the recording sheet 4 is processed for cents or jams, as shown in FIG.
If the configuration is such that the pressure roller llb is provided on the second housing B side, the recording sheet 4 will be in a free state when the second housing B is opened, making it easier to handle paper jams and paper jams. It becomes easier. In this case, it is effective to set recording sheets of frequently used sizes in the first holder 6.

Further, in the above embodiment, when sheet rolls of the same size are stored in the holders 6 and 7, one of the recording sheets, for example the recording sheet 4, is used during recording. When the recording sheet 4 runs out, the sheet presence/absence sensor 13a detects this, and the control section can also cause the other recording sheet 5 to be used. In this case, the recording sheet 5 has a reserve function.

In the above-mentioned embodiment, the rotational peripheral speed of the feed roller pair 11 (or 14) was set to be slightly faster than the rotational peripheral speed of the platen roller 8a, but recording is possible even if the rotational peripheral speed is not necessarily set as described above. It is capable of conveying the sheet 4.

Furthermore, in the above-mentioned embodiment, the platen roller 8a and the feed roller pair 11.14 were configured to be driven by suspending a belt between the respective pulleys and the drive motor. The driving force may be transmitted by gears. In this way, the second housing B can be opened easily.

Further, in the above-described embodiment, the seat holders were provided in parallel to the left and right in the first housing A, but they may be provided in parallel to the top and bottom.

Further, in the above-described embodiment, the platen and the feed member were each configured in the form of a roller, but as another example, a rotating heald suspended from 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 the first housing can store two sheet rolls, and each sheet is conveyed. Since the feed member, platen, and recording head are provided separately in both cylinders, it is possible to select and record a recording sheet that matches the received image size, and it is also easy to remove paper jams and remove paper jams. Furthermore, since the two sheet rolls can be seen when the housing is opened, the remaining amount of rolls can be confirmed at once. Furthermore, by using one sheet roll as a spare, it is possible to prevent reception failure due to running out of recording sheets.

In addition, since the platen and each feed member can be freely controlled by individual drive sources, it is possible to convey sheets with a high degree of freedom, and the sheet conveyance accuracy can be improved.
