This is a high-end model. A general-purpose machine generally has a combination of the items (1) and (2) at most.

[0003]

[Problems to be Solved by the Invention]

The purpose of the general-purpose machine, which is a combination of (1) and (2), is to save power when the machine is out of operation, but the operation panel is kept off, so the main switch is mistakenly turned off. Then, I forget to turn off the main switch, and it may operate in energy saving mode all night. In such a case, according to trial calculation, a certain model consumes as much as 2 kW of power overnight, which is contrary to energy saving.

[0004] Therefore, by connecting a popular machine to a power source through a commercially available weekly timer, as is done in general household electric appliances, the power source is automatically turned off after a certain time every day. There is a method of shutting off, but depending on the type of equipment, there are cases where power is supplied for actual operation and cases where power is supplied while not in use to maintain a good operating condition. For example, in a device such as a copying machine or an image reading device, the temperature inside the device decreases when the device is not operating. Therefore, a dew condensation prevention heater that prevents dew condensation of the optical system, a heat retention heater that removes moisture from the paper, etc. Is provided as needed. These are connected to the reverse contacts of the main switch and supply power when the main switch is turned off when not in use. However, the commercially available timer has only the function of supplying or shutting off the power uniformly, so that it is not possible to perform control to start power supply to other parts when the main switch is turned off. .

Is connected to the NO outlet 4 and a power supply unit (not shown) for supplying electricity to a dew condensation preventing heater (not shown) is connected to the NC outlet 5 without being directly related to the copying operation.
Now, in the state where the open / close sections 9 and 10 and the main switches 15 and 16 are closed, the open / close sections 11 and 12 are maintained in the open state. In this state, a copy is made by operating an operation unit (not shown) on the copying machine 17 side. Then, when a certain set time at night is reached, the relay coil 18 is maintained in a non-excited state by the timer / relay control circuit 13, whereby the movable contacts c of the opening / closing sections 9 to 12 are operated and the opening / closing sections 9 and 10 are operated. Is opened and the copying machine 17 is maintained in an unused state. At this time, since the opening / closing sections 11 and 12 are closed, the dew condensation preventing heater of the copying machine 17 is energized. That is, the copying machine 17 is switched to the unused state.

When a certain set time in the morning is reached, the relay coil 18 is excited by the timer / relay control circuit 13, whereby the movable contacts c of the opening / closing sections 9 to 12 are operated, and the opening / closing sections 9 and 10 are activated. The circuit is closed, and the opening / closing sections 11 and 12 are circuits. That is, the copying machine 17 is switched to the use state.

As described above, by operating the opening / closing sections 9 to 12 by the timer / relay control circuit 13 at the set time, it is possible to alternately output the voltages to the plurality of different NO outlets 4 and NC outlets 5. Therefore, power supply during operation and power supply during non-use can be performed without incorporating an expensive power supply control device in the copying machine 17. This is the effect corresponding to the invention of claim 1.

As a matter of fact, the copying machine 17 can be maintained in the unused state. Second, by operating the relay coil 18 by the logical sum of the timer output output when the time set in the timer / relay control circuit 13 is reached and the output of the illuminance detection sensor 22, the copying machine 17 is operated. Even when the time to set the non-use state is reached, if the surroundings are bright, it can be judged that the work has been extended and the copying machine 17 can be kept in the use state. Thirdly, the timer output that is output when the time set in the timer / relay control circuit 13 is reached and the output of the illuminance detection sensor 22 are output in a combination of a logical product and a logical sum, and the output is used for relaying. By operating the coil 18, the first method can be controlled in the morning and the second method can be controlled at night.

An AND circuit (not shown) that obtains a logical product and an OR circuit (not shown) that obtains a logical sum as described above execute the opening / closing operations of the opening / closing sections 9 to 12 in the present invention. Functions as a means for executing. In this case, the control mode can be arbitrarily set according to the usage environment of the copying machine 17. When the copying machine 17 is installed in a dim place, the output from the illuminance detection sensor 22 may be cut or adjusted by a volume (not shown).
