く、作業能率が悪い欠点があつた。 Conventionally, electronic copying machines have been provided with a fixing device equipped with a heating roller, and the surface temperature of the heating roller is maintained constant by controlling the power input to the heater within the roller. Furthermore, when the copying machine is turned on to use it, a display is displayed indicating that copying cannot be performed until the temperature of the heating roller reaches the fixing temperature. It is set in advance near the upper limit so that fixing is possible even if the fixing is performed. For this reason, even if a small number of copies can be made, a display indicating that copying is not possible until the fixing temperature is actually reached is displayed, resulting in long waiting times and poor work efficiency.

The aim is to shorten waiting time.

Electric power is supplied to the heater 2 via a power supply device 4 controlled by an arithmetic unit 3 having a built-in microcomputer or the like.
Reference numeral 5 denotes a temperature detector that detects the surface temperature of the heating roller 1 as a voltage, which is composed of a shim resistor 6 provided near the surface of the heating roller 1, and a circuit 7 that converts a change in the resistance value of the sam resistor 6 into a voltage. It is configured. The output of the temperature detector 5 is sent to the A/D converter 8.
After the analog quantity is converted into a digital quantity, it is input to the arithmetic unit 3, and the following arithmetic operation is performed based on the input data from the input and display device 9.

に達したとき複写が開始される。 When a copying machine (not shown) is turned on to start copying, power is simultaneously applied to the heater 2 from the power supply device 4 and heating of the heating roller 1 is started. Further, the surface temperature of the heating roller 1 is detected one by one by a temperature detector 5 and inputted to the calculation device 3, and the calculation device 3 inputs and displays the information to the display device 9 until the surface temperature of the heating roller 1 reaches a temperature that allows fixing. The input and display device 8 outputs a copy prohibition signal.
For example, the copy number display (not shown) is made to blink. After that, when the surface temperature of the heating roller 1 reaches a temperature at which one copy can be made, the output from the arithmetic unit 3 causes the input and display device 9 to display the number of copies that can be made to "0" and the set number of copies to display to "1". is set and continues to flash. Thereafter, as the surface temperature of the heating roller 1 rises, the display for the number of copies that can be made increases while blinking, and when the maximum number of copies that can be made is reached, the display for the number of copies that can be made becomes "0" and the display for the set number of copies changes to "1". At the same time, the temperature of the heating roller 1 is maintained constant. During this time, if the user inputs the desired number of copies using the numeric keys on the display device 9, this number will be displayed on the set number display, and if this number is smaller than the number of copies that can be made, the calculation device 3 will display the number of copies. A copy start signal is output to the drive system that does not operate, and copying is started. If the set number of copies is greater than the number of copies that can be made, copying is not started, but the copyable display blinks and increases in number, and when the set number of copies is reached, copying is started.

一定温度となるようにヒータ２を制御する。 That is, the microcomputer in the arithmetic unit 3 controls the heating roller 1 necessary to copy the set number of sheets.
The temperature T N of the heating roller 1 is compared with the actual temperature T R of the heating roller 1 detected by the temperature detector 5, and when T N T R , a normal processing routine is executed, and when T N > T R , T N -T R =ΔT is calculated, the time t required for the temperature rise of ΔT is calculated, and after the above operations are performed, the routine returns to the normal processing routine. In a normal processing routine, when the surface temperature of the heating roller 1 becomes higher than the upper limit, the power supply to the heater 2 is stopped, and when it becomes lower than this, the power is turned on again to keep the heater 2 at a constant temperature.

の点滅動作となる。 On the other hand, if the number of copies is large and the temperature of the heating roller 1 reaches a temperature that cannot be fixed during copying, the copying operation will be stopped and the display of the number of copies that can be made will blink, and then the temperature of the fixing roller 1 will recover and the remaining number of copies will be restored. When the required temperature is reached, the copying operation is automatically started again by the output from the arithmetic unit 3. During this time, it is no longer possible to reset the number of copies, but by clearing the set number with the clear key, the previous contents are also erased, and the display flashes in the same way as when the power is turned on.

ので、事務能率の向上も図れるようになる。 As described in detail above, in this invention, each time the fusing temperature of the fusing device reaches the number of sheets that can be fixed, the number is displayed on the display device. Copying can be started before reaching the end of the page, significantly reducing waiting time. Furthermore, when the number of copies that can be made is less than the set number, the copying operation automatically stops and waits for the fixing temperature to recover, so there is no risk of defective fixing, and the user is notified of the waiting time in advance. If you do this, you can engage in other work during this time, which will improve your office efficiency.
