Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat-sensitive recording facsimile device that enables multiple overlapping recordings.

The received recorded image that can be obtained by a facsimile machine is one communication unit, and it has been impossible to express the contents that change from time to time on the same received recorded image.

For example, when the format of the transmitted message is fixed and numerical values that occur from time to time are recorded in the fixed format, or when collecting numerical values etc. from a large number of senders in the fixed format, conventionally Since it was possible to obtain only one receipt record for each message, the receiving side had to tally up all the receipt records. SUMMARY OF THE INVENTION In order to eliminate such drawbacks, it is an object of the present invention to provide a device that can perform multiple overlapping recordings by simply adding simple functions to a normal thermal recording facsimile device.

The gist of this is that there is a means for marking a predetermined position on the recording paper before starting recording of the first receipt, and a means for reversing the recording paper line drawing mechanism after detecting the end of reception of the first receipt. means for moving the recording paper in the rewinding direction, detecting the position mark, stopping the movement of the recording paper in the rewinding direction and waiting after a preset time after the detection;
When the recording paper rewinding operation is specified in relation to the third general rule, the rewinding operation is repeated every time the end of reception is detected.

FIG. 1 is a perspective view showing an outline of one embodiment of the present invention.

In the figure, 1 is a roll-shaped recording paper, 2 indicated by a dashed dotted line is the received first letter, and 2' indicated by a dotted line is a waiting state for receiving the second letter with part 2 rewound. shows.

Now, when the transmitting side sends out, for example, "two" overlapping designation control signals prior to communication, the receiving side control section selects the signals and operates the mark mechanism 3. The mark mechanism 3 is a second
As shown in the schematic side view in the figure, in order to attract the plunger 102, which is energized by the solenoid 101, in the direction of arrow A, when two overlapped designation signals are selected in the reception control section, the lever 103 is moved with the lever 104 as the fulcrum. , move the mark member 105 in the direction of arrow B to make a position mark hole 4 on the recording paper 1.

Spring 106 is for return. At this time, a portion 2 indicated by a one-dot chain line on the recording paper 1 is unrecorded and corresponds to a position indicated by a dotted line 2'. Next, after phase alignment is completed in a well-known procedure in facsimile transmission, the first image signal is applied to the drive circuit 6 of the thermal head 5 to color the thermal recording paper. Also, at the same time as the phase alignment is completed, the electromagnetic clutch 9
is activated, the rotation of the motor 7 is transmitted to the driving roller 1 via the reduction gear 8, the loaf 10 rotates in the direction of the arrow, and a line is drawn on the recording paper 1 in the direction of the arrow F, thereby performing sub-scanning. The rotation of the motor 7 is controlled by a pulley 11, a belt 12,
Since the electromagnetic clutch 15 is not operating, the drive loaf 16 is transmitted to the reduction gear 14 via the pulley 13 in the direction opposite to the arrow shown in FIG. It's idling. 17 is a light source, 18 is a photodetector, and 19 is a delay circuit.The light from the light source 17 is normally blocked by the recording paper 1 and does not reach the photodetector 18.

Furthermore, this photodetector detects that the recording paper 1 is in the opposite direction of arrow F (F
It is in the operating state only during the period when it is moving in the ′ direction).

In this way, when the reception of the first message is completed and the end signal is received, the electromagnetic clutch 9 is released, the drive roller 0 is stopped, and the recording paper 1 is stopped with the recording portion 2 at the position shown in the figure.

Now, it is possible to give a fixed frequency as the end signal or give it as a code signal, and if the second message does not require overlapping recording, use the end signal indicating that overlapping recording is unnecessary. However, if overlapping recording is required,
An end signal indicating the need for overlapping recording is used. When the receiving device receives and identifies an end signal indicating that overlapping recording is unnecessary,
The process ends without rewinding the recording paper.

At the end of one round, a predetermined constant frequency signal is sent from the transmitting side and detected by the receiving side, or conversely,
A method is used in which a constant frequency signal is sent from the transmitting side only when overlapping recording is not required, and the signal is not sent when overlapping recording is necessary.

The receiving side includes a detection circuit 21 that detects a constant frequency signal, and performs rewind control depending on the presence or absence of a detection output. When an end signal indicating the need for overlapping recording is received and identified, the electromagnetic clutch 16 is operated after the first pass is completed, the drive roller 16 rotates in the direction of the arrow in the figure, and the recording paper 1 moves in the direction of the arrow F. ’ direction (the direction in which the paper is rewound).

The recording paper 1 moves in the direction of the arrow F', and the light from the light source 17 passes through the position mark hole 4, is detected by the photodetector 18, and is delayed by a delay circuit 19 for a certain period of time to operate the relay S. The delay circuit 19 corrects the difference in mechanical position between the photodetector and the position mark mechanism 3. Due to the operation of the relay S, the electromagnetic clutch 15 is released and the recording paper 1 is moved to the recording area 2 in the figure.
′ (indicated by a dotted line).

In this state, by electronically transmitting the second document from the transmitting side using the same procedure from phase signal transmission as the first document,
The second message is superimposed and recorded at the position where the first message was received.
Furthermore, if it is necessary to record the second, third, and fourth copies overlappingly, the same procedure as above may be followed. In addition, as a method for detecting the position of the recording paper, instead of using the mechanical method as explained above, it is natural to think of a method in which position marks are colored and recorded on the thermal recording paper outside the effective recording width, and then detected using a reflective sensor. In addition, a method of stamping with ink is also considered.

Further, it is possible to use the end signal as a signal for rewinding the recording paper, and it is also possible to give a rewind designation signal in advance at the start of transmission, and various modifications can be made without departing from the spirit of the present invention. It is possible to implement.
