Abstract

PURPOSE:To reduce the communication time and to prevent the wear of recording head by specifying the head location of a recording sheet after the end of recording of one page in an equipment of double roll type. CONSTITUTION:Recording sheets 4, 5 of sheet rolls 4a, 5a contained respectively to roll holders 6, 7 are carried to a recording section 8 and subject to recording of reception picture information. After the reception picture information by one page is recorded, a signal representing the end of picture information transmission sent from the sender side is a multi-page signal, then the tip of the recording sheet recorded just before, e.g., the sheet 4 is restored to the recording position of a recording section 8. Thus, in recording picture information of the same size by plural number of pages consecutively, the operation after the end of the recording of a page is finished till the next page recording is started is fast and the communication time is reduced. Moreover, the wear of recording head 8b by the platen roller is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a recording method in which a plurality of recording sheet rolls are stored and one of the recording sheets is selected for recording.

[Prior Art] In conventional desktop type recording methods such as facsimile machines and printers, a sheet roll of a predetermined size made by winding recording sheets is stored, and the recording sheets are sequentially fed out. The system is configured to record received image information while

[Problems to be Solved by the Invention] However, in the above configuration, if the set recording sheet is, for example, A4 size, when receiving and recording B4 size image information, this must be reduced. It is necessary to record the On the other hand, when a B4 size recording sheet is set and A4 size image information is received and recorded, there is a problem in that a blank space is generated on the recording sheet.

There is also a method of recording using a so-called double roll type device that can store two sheet rolls to solve the above problem, but conventional devices of this type are of a large console type, and the recording sheet The setting method was also complicated and not easy to use.

Furthermore, in conventional double roll type devices, the standby positions of the leading ends of both recording sheets are always set upstream of the recording section, so when the first page is finished recording, the leading ends of the recording sheets are returned to the waiting position. When recording the next page, one of the recording sheets was conveyed to the recording section and recorded. However, when recording image information of the same size continuously over multiple pages, the leading edge of the recording sheet does not need to be pulled back upstream from the recording unit, and if the above wasteful operation is performed, the communication time is In addition, since the platen roller rotates in direct pressure contact with the recording head before recording starts, the recording head may wear out and shorten its life, and jams may occur when the leading edge of the recording sheet enters the recording section. This caused problems such as recording failure at the leading edge of the recording sheet, etc.

On the other hand, when recording with different width sizes is performed alternately, the leading edges of both recording sheets must be in a normal standby position.

The present invention solves the above-mentioned conventional problems and provides a recording method in which two recording sheet rolls are stored and the leading edge of the recording sheet is set at an appropriate standby position as required after one page has been recorded. This is what I am trying to do.

[Means for Solving the Problems] The present invention stores first and second rolled recording sheets in a first casing, and transports either one of the recording sheets to a recording section in accordance with a predetermined signal. After recording the received image information and recording the received image information for one page, if the signal sent from the transmitting side indicating the end of image information transmission is a multi-page signal, the recording sheet that was recorded immediately before is This is to return the tip to the recording position.

[Function] The present invention stores first and second rolled recording sheets in a first casing, and transports one of the recording sheets to a recording section in response to a predetermined signal to record received image information, After recording one page of received image information, if the signal sent from the transmitting side indicating the end of image information transmission is a multi-page signal, the leading edge of the recording sheet that was being recorded immediately before is returned to the recording position. , when recording multiple pages of image information of the same size in succession, the operation from the end of recording one page to the start of recording the next page is quick, reducing communication time and preventing the occurrence of jams. , it is possible to prevent recording omissions at the leading edge of the recording sheet, and it is possible to prevent wear of the recording head due to the platen roller.

In addition, the display unit 18, manual car/topotan 17, recording sheet presence/absence detection sensors 13a, 16b, recording sheet width detection sensors 13b, 16b, recording motor 8e, feed motor fl
b, 14b, a cutter motor 9b, a recording head 8b, and a cover switch 70.

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 setting the sheet roll as described above, the second housing B is closed and a manual cutting operation is performed.

To explain this operation, first, the feed roller 11 and platen roller 8a rotate in the direction of the arrow shown in FIG. . Further, the cut recording sheet 4 is discharged out of the apparatus, and the platen roller 8a and feed roller 11 are rotated in the opposite direction to the above, so that the leading edge of the recording sheet 4 is placed downstream of the sheet presence/absence detection sensor 13a and the sheet width detection sensor 13b. It is rewound to a predetermined position on the upstream side of the recording unit 8 and placed in a standby state. Next, the leading edge of the recording sheet 5 is cut by operating the feed roller 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 detected by the sheet presence/absence detection sensor 16a and the sheet width. Detection sensor 1
It is rewound to a predetermined position on the downstream side of 6b and upstream of the recording section 8 and placed in a standby state.

The leading edge of the recording sheet 4.5 is made clean by the above-mentioned manual cutting operation, and by controlling the rotation amount of the platen row 8a and the feed roller 11.14 by the control unit shown in FIG. lead to.

Next, recording will be described using FIG. 12, for example, in the case where image information transmitted from another facsimile is recorded.

First, upon reception (Sl), a recording sheet suitable for the width of the received image is selected within the image information reception procedure time (S2). 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, and the feed roller 11 rotates in the direction of the arrow in FIG. 4 is conveyed to the recording section 8 within the above-mentioned time (S3).

Next, 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 drive 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. The recording sheet 4 is conveyed at a constant speed. In synchronization with this conveyance, the recording head 8b generates heat according to the image information, and the received image information is recorded on the recording sheet 4 by the generated heat (S4). At this time, the feed roller 11 rotates 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 until the trailing edge position of the image reaches the cutter 9 and cut. At the same time, the platen roller 8a and the feed roller 11 rotate in the direction opposite to the arrow in FIG. 3, and the leading edge of the recording sheet 4 is rewound to a predetermined standby position.

Recording of the A4 size received image is completed as described above.

Here, the standby position of the leading edge of the recording sheet after recording and cutting the first page will be described. CCITT,
According to the binary procedure recommended for T2O, at the end of a page of facsimile information, the sender sends EOP (end of procedure signal) and MPS as post message commands.
(multipage signal) and EOM (end of message signal). Hereinafter, the specific procedure and the set standby position of the leading edge of the recording sheet will be explained assuming that each signal is sent out after the completion of A4 size recording.

First, the fourth case is when EOP (procedure end signal) is sent.
This will be explained with reference to the drawings and FIG.

EOP indicating the end of the image information after the image information from the sending side
(procedure end signal) is sent. When the receiver receives the EOP (procedure end signal), it sends an MCF (message confirmation signal) to indicate that the message has been completely received.

When the sending side receives the MCF (message confirmation signal), it sends the DC
Sends N (disconnection command signal) and terminates communication. In other words, when the receiving side receives an EOP (procedure end signal) after recording image information, it does not record any more within the same communication, and it does not decide which of the two sheet rolls to use in the next communication.
It will be determined at the start of the next communication. Therefore, when an EOP (procedure end signal) is received, the leading edge standby position of the recording sheet 4 is the same position as the leading edge standby position of the sheet 4 after manual cutting, that is, downstream of the sheet presence/absence detection sensor and the sheet width detection sensor. It is set at the position shown in FIG. 5 on the upstream side of the recording section 8 (S7).

Next, MPS when multiple pages are sent consecutively (
Figures 6 and 1 show the case where a multi-page signal) is sent.
This will be explained using Figure 2.

An MPS (multi-page signal) is sent from the transmitting side after the image information, indicating the end of the page of image information and also indicating that the next page without a mode change will continue. When the receiver receives the MPS (multipage signal), it sends an MCF (message confirmation signal) to indicate that the message has been completely received. When the sending side receives the MCF (message confirmation signal), it sends out the image information of the next page, which has the same width as the previous page.

That is, when the receiving side receives an MPS (multi-page signal) after recording image information, it records the next page using the same sheet roll as the previous page.

Therefore, when an MPS (multi-page signal) is received, the leading edge of the recording sheet 4 does not need to be returned to the upstream side of the recording section 8, and the recording sheet leading edge standby position is as shown in FIG. It is sufficient to set the position downstream of the printing position 8C by the length of the margin at the leading edge of the recording sheet during recording (S8).

Next, FIG. 8 shows a case where an EOM (end of message signal) is sent.

EOM (message end signal) after image information from the sending side
is sent, indicating the end of the page of image information and indicating that the next page with a mode change will follow. The receiving side is E
When it receives an OM (message completion signal), it sends out an MCF (message confirmation signal) to indicate that the message has been completely received, and after a certain period of time, it sends out a DIS (digital identification signal) and has a CCITT standard receiving function. Show that. When the transmitting side receives DIS (digital identification signal), it sends out DOS (digital command signal) and DI
7 Indicates the function to be installed from among the standard functions displayed in S. When the receiving side receives the DOS, it detects the width size of the received image information of the next page, selects the recording sheet 4 or recording sheet 5 of the corresponding size, sends a CFR (receiving preparation confirmation signal), and completes the process before sending the message. Indicates that the procedure is complete and message sending can begin. When the sending side receives a CFR (reception preparation confirmation signal), it sends out image information as facsimile data. When the receiving side receives the facsimile data, the recording head 8b generates heat in accordance with the image information, and the recording section 8 starts recording.

That is, the receiving side knows that the next page exists by receiving an EOM (message end signal) after recording image information, but does not know the width size of the next page until it receives a DOS (digital command signal). Therefore, when an EOM (message end signal) is received, the leading edge standby position of the recording sheet 4 is the same position as the sheet leading edge standby position after manual cutting, that is, the width is on the downstream side of the sheet presence/absence detection sensor 13a and the sheet width detection sensor 13b. and set it at the position shown in FIG. 5 on the upstream side of the recording section 8 (S7).
.

Here, the drive of the feed roller and platen roller is controlled by a control section, and its configuration is as shown in FIG. 9, in which a recording operation signal is transmitted from the CPU to a motor drive circuit, and the motor is driven via the circuit. do. At this time, the number of rotational steps of the motor is calculated by the step pulse calculation circuit.

Therefore, when rotating the motor sequentially, it is important to check whether the leading edge of the recording sheet 4 has been conveyed from the standby position to the recording section 8, and whether the trailing edge of the recorded image has been conveyed from the recording section 8 to the cutter 9 position after recording is completed. is detected by counting the number of rotational steps of the motor with a step pulse calculation circuit, and when the motor is rotated in reverse, it is detected whether the leading edge of the sheet has been rewound from the cutter 9 position to the recording section 8, and whether or not the sheet tip has been rewound from the cutter 9 position to the recording section 8. It is detected in the same manner as described above whether or not the motor has been rewound to the standby position, and the CPU drives, stops, and controls the speed of the motor in accordance with the signal from the step pulse calculation circuit.

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 section 8, and cutter 9 It operates in the same manner as above to perform B4 size recording on the recording sheet 5.

That is, when the recording sheet 5 is selected at 82 in FIG. 12, operations 53' to 58' are performed in the same manner as S3 to S8 described above.

Next, in handling a jam, etc., the hook 3 is unlocked and the second casing B is opened. At this time, since the respective feed roller pairs 11 and 14 are provided separately 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. Further, when the second housing is opened, each of the sheet rolls 4a and 5a can be viewed at the same time, so it is possible to easily check the remaining amount of the rolls.

Also, when setting the sheet roll, the platen roller 8a and recording roller 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. Therefore, as shown in FIG. 10, for example, the leading edge of the recording sheet 4 to be set is passed between the pair of feed rollers 11, and also passed along the platen roller 8a through the gap between the cutters 9 and between the pair of discharge rollers 10. By guiding it out of the apparatus, it can be easily and reliably set, and it is also possible to easily prevent the recording sheet 4 from being set diagonally during setting. 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.

When setting or jamming the recording sheet 4, as shown in FIG. If the pressure roller itb to be pressed is provided on the second housing B side, the recording sheet 4 becomes free when the second housing B is opened, making setting and jam removal 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 detection 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.

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

Further, in the above-described embodiment, the platen and the feed member are each formed of roller-shaped members, but as another example, a rotating belt suspended from a bobbin or the like may be used.

FIG. 14 is a flowchart showing the operation of another embodiment of the present invention.

In this flowchart, the same operations as those shown in FIG. 12 are given the same reference numerals.

The operation shown in FIG. 14 differs from the operation shown in FIG. 12 in the following points. That is, after cutting a predetermined page while recording on the recording sheet 4 (S5), if the recording sheet 4 currently being recorded remains (S5a), the control signal is determined (S6).
However, if recording sheet 4 does not remain at that time, it is determined whether recording sheet 5 remains or not (55b), and if recording sheet 5 remains, recording is restarted using recording sheet 5.

In other words, the process advances to S6'. In addition, in the above case, record sheet 4
When the recording for one communication is completed (S6), if there is no recording sheet 5 (S6a), return the recording sheet 4 to the recording position (S6 b) and wait, and if the recording sheet 5 remains Return the recording sheet 4 to the standby position.

Similarly, while recording on recording sheet 5, a predetermined page was cut (
After S5'), if the recording sheet 5 currently being recorded remains (S5a''), the control signal is determined (S6'), but if no recording sheet 5 remains at that time, it is determined whether the recording sheet 4 remains. To judge whether or not S5b'), record sheet 4
If remains, recording is resumed on recording sheet 4. In other words, the process advances to S6. In the above case, when recording on recording sheet 5 ends for one communication (S6°), if there is no recording sheet 4 (S6a''), return recording sheet 5 to the recording position (Sob') and wait. However, if the recording sheet 4 remains, the recording sheet 5 is returned to the standby position.

That is, when the signal indicating the end of image information transmission is other than the multi-page signal, the leading edge of the recording sheet that was being recorded immediately before is returned to the standby position. In addition, when the signal indicating the end of image information transmission is other than a multi-page signal and there is no recording sheet other than the recording sheet recorded immediately above, the leading edge of the recording sheet recorded immediately above is set to the recording position. Set to .

[Effects of the Invention] According to the present invention, when multiple pages of image information of the same size are continuously recorded, the operation from the end of recording one page to the start of recording the next page is quick. This has the following effects: communication time can be shortened, jams can be prevented, recording is not recorded at the leading edge of the recording sheet, and wear of the recording head due to the platen roller can be prevented.
