Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording device for facsimile, and more particularly to a recording device suitable for taking out predetermined recording paper by after-cutting continuous paper fed from a roll.

In this type of conventional recording device, when the recording of one original document is completed on continuous recording paper, the recording paper is transported to the cutter position, and when the leading edge of the recorded image reaches the cutter position, the leading edge of the recorded image is first The margin part is cut, and then when the trailing edge reaches the cutter position, it is cut again to take out the designated received image recording paper, and at that point, the continuous feeding of the recording paper is stopped in preparation for recording the next document. was.

For this reason, the cutter must be operated twice to obtain one sheet of recording paper, and the margin at the leading end is wasted, which has the disadvantage of accelerating the wear of the cutter and wasting the recording paper.

Therefore, in order to eliminate this drawback, as a conventional example, after recording one document, the recording paper transferred to the cutter position is cut only at the rear edge of the received image. A recording apparatus has been proposed that returns the leading edge of successive recording sheets to the recording position and performs the next recording.

However, although this device eliminates the above-mentioned drawbacks, when receiving multiple sheets of originals continuously from the sending side, each time a sheet of recording paper is taken out, the leading edge of the consecutive recording sheets is Even if a buffer memory is provided to store the image information sent from the sending side during that time, the buffer memory will become full while receiving multiple sheets of originals in succession. Therefore, the sending of image information from the transmitting side had to be temporarily stopped, which inevitably resulted in longer communication times and higher telephone charges.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a recording apparatus that can eliminate the recording paper margins and shorten the communication time, while eliminating the drawbacks of the prior art described above.

In order to achieve this object, the present invention continuously records image information for multiple sheets of originals sent on continuous recording paper one after another during continuous reception, while the trailing edge of the received image recording paper is The recording paper is characterized in that it is configured to cut each time it reaches the cutter position, and to return the leading edge of continuous recording paper to the recording position when one communication is completed.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram illustrating a main part of a signal processing section of a recording apparatus according to an embodiment of the present invention, and FIG. 2 is a diagram showing a main part of a mechanical section thereof.

In the figure, 1 is a system controller. This system controller 1 outputs signals a to c in response to MPS (multipage signal), EOM (end of message signal), and EOP (procedure end signal) sent from the transmitting side. Further, during reception, a reception mode signal d and a recording paper transport pulse e are also output.

2 and 3 are preset registers in which the number of pulses necessary to transport the recording paper from the recording position to the cutter position is set; 4 and 5 are input the numbers set by preset registers 2 and 3 to the CK terminal. This is a counter that subtracts according to the pulse and outputs carries f and g when it reaches 0.

As shown in FIG. 3, 6 is a delay circuit which outputs a cutter drive signal h at the same time as the carry f occurs, operates the cutter drive device 7, and outputs a delay signal i in anticipation of the cutter operation time. be.

8 depends on the mode signal j input to the M terminal.
A reversible counter that reversibly counts the pulses input to the CK terminal; 9 is a drive signal that corresponds to the count value of the reversible counter 8; for example, as shown in FIG. A phase encoder outputs 1-2 phase excitation signals, and 10 is a pulse motor drive circuit.

In FIG. 1, 11 to 13 are flip-flops, 14 to 19 are AND gates, and 20 to 22 are OR gates.

The phase excitation signal output from the pulse motor drive circuit 10 is applied to the pulse motor 23 in FIG.
The platen roller 24 is driven. As a result, the continuous recording paper 26 unwound from the roll 25 is transported, and the recording head 27 records image information.

Further, the cutter rotation teeth 28 are rotated by a drive signal outputted from the cutter drive circuit 7, and the recording paper 26 is cut in cooperation with the fixed teeth 29, and the recording paper 31 is taken out onto the tray 30.

Next, the operation will be further explained with reference to the recording paper transport state diagram of FIG. 5 and the flowchart of the facsimile control procedure of FIG. 6.

At the time of reception, each counter and flip-flop are reset, the system controller 1 outputs a reception mode signal d, and the gate 16 is opened. Further, the leading edge of the recording paper 26 is stopped at the recording position shown in FIG. 6a.

As shown in FIG. 6, when reception of facsimile data is started, the facsimile controller 1
applies image information to the recording head 27, and outputs a recording paper transport pulse e in response. This pulse e is input to the CK terminal of the reversible counter 8 via the gates 16 and 22. At this time, since the mode signal j input to the M terminal is at the "H" level, the counter 8 performs a counting operation in the positive direction.

After the count value of the counter 8 is converted into a drive signal by a phase encoder 9, it is input to a drive circuit 10,
Drive the pulse motor 23.

As a result, the platen roller 24 rotates and the fifth
As shown in FIG. b, the recording paper 26 is transported to the cutter position in accordance with the recording speed.

As shown in Figure 6, when facsimile data for one document is sent from the sending side and then facsimile data for the next document is sent, MPS or EOM is Sent out.

Upon receiving this MPS or EOM, the receiving side system controller 1 returns a response signal to the transmitting side, and upon completion of recording, stops transporting the recording paper 26 and outputs a signal a or b.

This signal a or b is supplied to the flip-flop 12.
is set, gates 14 and 15 are opened, and the preset value of register 2 is transferred to counter 4 by inputting it to counter 4.

Next, when reception of facsimile data is started, the system controller 1 again applies image information to the recording head 27 and outputs a recording paper transport pulse e.

Pulse e output from system controller 1
transports the recording paper 26 and at the same time subtracts the preset value of the counter 4. Eventually, recording paper 2
When the rear end of the received image recorded on 6 reaches the cutter position, the counter 4 also becomes exactly 0 at the same time, and the carry f outputs.

Simultaneously with the output of the carry f, the delay circuit 6 outputs the cutter drive signal h to operate the cutter drive circuit 7. As a result, the cutter 28 operates and the recording paper 26
cut. Therefore, only at this time is the predetermined received image recording paper 31 on which the image information sent earlier recorded is taken out onto the tray 30.

During this time, the recording operation continues, and eventually, as in the previous case, the sending side sends out all the facsimile data for one page of the original, and then again if it plans to send out more facsimile data.
Send MPS or EOM.

Hereafter, repeat the above series of operations, and
As shown in the figure, when the sending side finishes sending facsimile data and there is no facsimile data to send after that, the sending side sends an EOP signal.

When the receiving side system controller 1 receives this EOP, it returns a response, and after recording the image information of the facsimile data, it temporarily stops transporting the continuous paper and outputs the signal c.

This signal c sets flip-flop 11 and opens gates 17 and 18. At the same time, flip-flop 12 is set via gate 20 as in the previous case, gates 14 and 15 are opened, and the value of register 2 is preset in counter 4.

Next, the system controller 1 outputs a recording paper transport pulse e to transport the recording paper 26. As in the previous case, when the rear end of the received image eventually reaches the cutter position, the carry f is output from the counter 4, inputted to the counter 5 via the AND gate 17, and the preset value of the preset register 3 is set. At the same time, a signal h is output from the delay circuit 6 to operate the cutter 28.

After the cutter operation is completed, the delay pulse i output from the delay circuit 6 sets the flip-flop 13 via the AND gate 18, sets the mode signal input to the reversible counter 8 to "L" level, and opens the AND gate 19.

As a result, the pulse e subsequently outputted from the system controller 1 is input to the reversible counter 8, and its value is counted in the reverse direction, while at the same time the preset value of the counter 5 is subtracted.

Due to the reverse counting operation of the reversible counter 8, the pulse motor 23 is driven in the reverse direction, and the platen roller 24
is driven in the opposite direction to return the leading edge of the recording paper 26 from the cutter position to the recording position.

When the leading edge of the recording paper 26 eventually returns to the recording position as shown in FIG. 5d, the value of the counter 5 also becomes 0, and the carry g outputs.

This carry g is input to the system controller 1, and the reception state is completely terminated. That is, one communication is completed with the leading edge of the recording paper stopped at the recording paper position, and preparation is made for recording during the next communication.

As a result, a predetermined amount of recording paper can be obtained without creating any wasted blank space, and in the case of continuous reception, without any waiting time.

Incidentally, since the preset registers 2, 3 and counters 4, 5 in the above embodiment are used at different times, it is clear that only one of each can be used.

As described above, according to the present invention, during continuous reception, image information for multiple sheets of sent originals are recorded one after another on continuous recording paper, while the rear edge portion of the received images is The paper is cut every time it reaches the cutter position, and when one communication is completed, the leading edge of the continuous recording paper is returned to the recording position.
It is economical as there is no wasted blank space, and at the same time, there is no need to feed the recording paper to the cutter position and return it to the recording position every time image information for one document is received, unlike in the past. , there is no need for a buffer memory to store the image information sent during that time, there is no waiting time at all, and the communication time is shortened. Furthermore, the number of reciprocating movements of the recording paper over the recording head is reduced, resulting in less wear on the recording head and increased service life. Moreover, the number of operations of the cutter is reduced, and its lifespan is extended.
