Abstract

(57) [Abstract] [Purpose] The power is suspended during the preset time period of the copying machine, and then the power is resumed so that there is no power consumption during the unused period. [Configuration] A switching element is provided between the power switch and the load, and the element is controlled by a control circuit such as a timer that uses a battery as a power source to suspend the energization for a predetermined time zone, and other time zones Is configured to energize. [Effect] The power is automatically stopped during lunch breaks, such as at night, so that power is not consumed during periods of non-use.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

  This invention relates to an improvement of a copying machine.

[0002]

[Prior art]

  The conventional copying machine is energized by turning on the power switch, and Copying is possible after the heat time has passed. On the other hand, power is turned on by turning off the power switch. It will be stopped.

[0003]

[Problems to be solved by the device]

  Normally, factories do not use copying machines during lunch breaks, , The light is turned off, but the switch of the copying machine is not turned off so much. Therefore, even during lunch breaks, electricity is consumed while the power is on. This kind of thing It's a waste of power and something that needs to be improved, but often power The actual situation is to leave it as it is without turning it off. Moreover, in the conventional copying apparatus, It was not designed to be able to automatically turn off the power at certain times .

[0004]   The present invention is intended to improve such a conventional problem, and to set a predetermined time. Power to the copying machine is automatically turned off in the band, and power is turned on again after that time period. The feature is that it is automatically turned on.

[0005]

[Means for Solving the Problems]

  Separate from the normal power on / off switch, switching in series with this power switch An element is provided, and a timer for controlling the energization off and energization on .

[0006]

[Action]   The switching element is controlled so as to be normally off during a predetermined time period, and After that, the timer is controlled so that the power is turned on again.

[0007]

【Example】

Example 1.   FIG. 1 shows an embodiment of the present invention, in which 1 is a power switch and 2 is a power switch. These are normally-closed contacts connected in series, and these contacts are connected to the load 3 such as the copying mechanism. When the power is turned off, it is opened, and when it is turned on, it is in the illustrated state. 4 will be described later A battery that allows a timer to function even when the power is off, and is not shown The electric power is charged through the charging circuit of. 5 converts the output of the battery 4 into alternating current The converter, 6 is a timer, similar to the timer used in video etc., The set time can be changed by operating the push button switch. 7 receives the time signal 8 as a control signal output from the timer 6, and receives the normally closed contact 2 It is a controller that controls the exciting coil 9.   The time control by the timer 6 is performed as illustrated in FIG. That is, Ima 6 pauses from 12:00 to 13:00, runs from 13:00 to 20:00 Power, pause from 20:00 to 08:00, energize from 08:00 to 12:00. If the preset time comes, the normally closed contact will open even if the power switch is ON. Release the power to turn off the power, and then the normally closed contact closes after a predetermined time. Re-energize. In this way, the program for the set time is used to communicate to the copying machine. Power is turned on and off.

[0008]   By the way, the copying machine cannot be used immediately after the power is turned on. Preheat time is required. Therefore, turn on the power a little before the actual start time. It is better to start and preheat. For this reason, preheating should be started before the start of surface energization. .

[0009]   That is, for example, when the energization start at 13:00 is taken as an example, the re-use starts at 13:00. If it is the beginning, it is necessary to start preheating about 10 minutes before that. Ie 1 Turn on the power around 2:50 minutes so that you can actually copy from 13:00 .

[0010] Example 2.   FIG. 3 shows another embodiment of the present invention. FIG. 3 (a) shows that when the contact 2 is opened, A device in which a voltage is applied to the display element 11 through another contact 10 so that the display element 11 emits light. , Which indicates that the copying machine is idle. Also, FIG. 3 (b) is a contact 10 and the flicker signal generator 12 is connected to the AND gate 13. By doing so, the display element 11 can be blinked. This makes the copying machine It will inform the surroundings more clearly that it is in the dormant state. By the way, energize If you want to make an emergency copy during the downtime, reset the contents of timer 6 to zero. Then, it is necessary to restore the contact 2. To do so, operate switch 14 The operation signal 15 of is supplied to the timer 6 as a reset signal and the contents of the timer 6 are initialized. Put in a state.

[0011]

[Effect of device]

  This idea has been described above. There is an effect that the power supply to the band can be stopped and wasteful consumption of electric power can be prevented. Note that In the embodiment, the contact element is used as the switching element, but the contactless switch is used. It goes without saying that the same applies to the ching element. In addition, the battery Since the control circuit such as the controller is controlled, the control can be performed even when the energization is stopped.
