Abstract

PURPOSE:To simplify a counter circuit by using properly the timepiece counting part of a facsimile transmitter as a monitoring for reservation setting time of day and as the monitoring for the transmitting time of every page of the data of a picture image. CONSTITUTION:When the reservation setting time of day comes, an alarm signal from a timepiece counting part 61 is outputted and a main power source making signal is outputted by sending a set signal to an FF 64 from a selector 63 and a main power source circuit 12 is started up. Thereupon, a main control part 3a makes a switching command as ON and switches the alarm output of the timepiece counting part 61 that is inputted to the selector 63 to the side for monitoring one page transmit ting time and performs a communication operation with making the timepiece counting part 61 to count a time value T that is set at every time when the transmission of one page is commenced. At a normal case, before the counting is reached at the setting time value T, an initial state is restored by transmission completion and the above operation is performed again. At an abnormal case,the counting goes to the time value T and the alarm signal is outputted from the timepiece counting part 61 and as the interruption signal of the main control part 3a, a device is controlled to return to the initial state.

Unit (hereinafter referred to as NCU) 9 has a function of controlling connection and disconnection of the circuit switching network. The automatic calling section 10 has a function of calling a receiving station by automatic dialing at a predetermined time based on a command from the main control section 3.

With this configuration and function, when transmitting, the operator first inputs the code of the destination from the operation unit 4, calls the receiving station, and operates the transmission S port.The operator connects to the destination and sends the original. 1 is read by the image sensor, converted to image data, sent to the main control unit 3, converted into binary values and compressed, and then the image data is modulated by the modem 8 under the control of the transmission control unit 7 for each page. The signal is sent to the receiving station via the NCU 9 on the line.

At the receiving station (here, the operation of the receiving station will be explained using the receiving function in Fig. 3), the received image data is sent to the main controller 3.
The data is expanded and sent to the recording section 5, where it is recorded on recording paper.

When a predetermined time is reserved for transmission, the time is set in advance in the timer 68 of the clock section 6, and when the time comes, a signal is output and a line is connected by automatic dialing of the automatic transmission section 10.

When transmission is started, a one-page transmission timer 6b monitors the transmission time for each page, and when the time count reaches a set time value, transmission is stopped and the device is returned to its initial state.

[Problem that the invention seeks to solve]

As mentioned above, in the conventional method, the set time value for monitoring the transmission time for each page ranges from several tens to several tens depending on the type of device.
The problem is that the time is measured in units of 0 minutes, and many counter circuits are required.

[Means for solving problems]

FIG. 1 shows a block diagram of the principle of the present invention.

In the figure, 61 is a time counter that monitors the set time while waiting for the power to be turned on, and after the power is turned on, monitors the transmission time of image data for each page using the set time value, and 62 is the power that is sent from the time counter. This is a switching unit that switches between a signal to be input and a signal to be transmitted when a set time value has been counted. A power-on signal is outputted from the time counting section 61 at the set time and sent to the switching section 62, and after the power is turned on, a signal sent from the time counting section 61 when the set time value is counted is sent to the switching section 62. It is configured as follows.

[Effect]

When a power-on signal is sent from the time counting section 61 to the switching section 62 at the reserved set time, the signal is sent to the power supply circuit and the power is turned on. Then, a switching command is given to the switching unit 62 to switch the output light, and when the signal that is emitted when the set time value is counted by the time counting unit 61 is sent to the switching unit 62, it is output as an interrupt signal and transmitted. Return to initial state. By switching the function of the time counter 61 between monitoring the set time and monitoring the set value of the true transmission time in this way, the counter circuit can be simplified and costs can be improved.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the block diagram of FIG.

In the drawing, the area indicated by the left and right dashed lines corresponds to the clock section 6 of FIG. 3 described in the conventional example, and the area outside the left and right dashed lines indicates the main control section 3a.

The main control section 3a has a function of controlling a clock section 60 in place of the function of controlling the clock section 6 of the main control section 3 described in the conventional example.

The clock section 60 includes a time counting section 61. which will be explained next. It includes a switching section 62 and the like.

The time counting unit 61 receives and sets a transmission time input from an operation unit (not shown) and a time value T for monitoring the transmission time of one page of image data from the main control unit 3a, and waits for the power to be turned on. It has a function of monitoring the transmission time at the time of transmission and also monitoring the set time value T after the power is turned on.

The switching unit 62 switches the selector 63 in the range shown by the two-dot chain line.
．． Flip-flop (hereinafter referred to as FF) 64° and NO
It is composed of 65 and 66 T circuits.

The selector 63 outputs the output light of an alarm signal, which is a signal sent from the time counting section 61 when a predetermined time is reached, and a notification signal sent when the transmission time of one page of image data reaches a set time value. This is the switching unit that performs switching. That is, in the figure, under normal conditions, the signal from the time counter 61 is F.
When a switching command is input to F64 from the main control unit 3a, it is switched and output as an interrupt signal.

The FF 64 sends a power ON signal to the main power supply circuit 11 in response to a set signal sent from the selector 63, and when a power OFF signal is input to the main control unit 3a, it sends a power OFF signal to the main power supply circuit 11, and the main control unit 3a is on standby. state.

Since it has such a configuration and function, the operation shown in FIG. 2 will be explained as follows: 1. Until the reserved set time is reached, that is, when the power is on standby, the time counting unit 61, Selector 63. and FF64 are operating.

■The switching command of the selector 63 is switched by the main control unit 3a when the main power is turned on, and the NOT circuit 6
5 is oven collector controlled, so during standby, the clock output is always connected to the FF 64 for turning on the main power.

■When the reserved time arrives, an alarm signal is output from the time counting section 61, a set signal is sent from the selector 63 to the FF 64 to output a main power supply turn-on signal, and the main power supply circuit 1
Start 2.

(2) Then, the main control section 3a turns on the switching command, switches the alarm output of the time counting section 61 input to the selector 63 to the one page transmission time monitoring side, and sets the time counting section 61 to the one page sending time monitoring side.
The communication operation is performed while counting the set time value T every time transmission of a page is started.

(2) In the normal case, when the count does not reach the set time value T, the transmission ends and returns to the initial state and operates again.

■In the case of an abnormality, counting is performed up to the time value T, an alarm signal is output from the time counting section 61, and the main control section 3a
This interrupt signal is used to return the device to its initial state.

■When returning to the power-on standby state, after setting the reserved time in the time counter 61, turn on the power OFF signal from the main control unit 3a to turn off the FF 64 and turn off the main power supply. Put it on standby.

In this way, the time counting section 61 can be used to monitor the reservation setting time and to monitor the transmission time of image data for each page, so the counter circuit can be simplified.

〔Effect of the invention〕

As explained above, according to the present invention, the counter circuit can be simplified and the cost can be improved.
