Sample uses clutch to control to various load supplyings.
For example, as load ADF registration roller, fixing prelocalization roller, various carrying rollers can be enumerated, for detecting paper
Deng sensor, CPU etc..
As the method that powers to the load of control, there is known control clutch, using clutch connection secondary-side circuitry with
The method of load, such as the method for control REM.Specifically, by the opening signal and shutdown signal that change REM, to switch
State that clutch is fully connected, the state being kept completely separate.
Specifically, as shown in figure 3, REM signal is not exported in the case where being not desired to drive shaft, thus clutch and axis
It disconnects and becomes the not state of drive shaft completely.In the case where thinking drive shaft, REM signal is exported, so that clutch and axis connect

As shown in figure 5, control unit is supplied to the clutch as interconnecting piece in the case where being not desired to axis of the driving as load
(i.e., axis attract and the voltage of the critical state without attraction, in other words, right to preset critical voltage V1
The voltage for the critical state that axis will be attracted) and REM signal is not exported, to make at the connection status of clutch and axis
In the second state.In the case where thinking driving load, the critical voltage V1 supplied to clutch is promoted to work electricity by control unit
Press V2 (in the present invention be, for example, 24V, but not limited to this, can as the case may be such as load type and arbitrarily become
REM signal more) and with 100% duty ratio is exported, to make the connection status of clutch and axis from the second state to first
State switching.

It should be noted that clutch is coil component, if applying voltage to it, clutch can be produced because of electromagnetic induction principle
Magnetisation and attract axis, and voltage is bigger, and attraction is bigger.Accordingly, there exist to axis carry out attract with without the upper of attraction
State critical voltage V1.As described in above-mentioned first embodiment, be not desired to attract axis when apply critical voltage V1 and
REM signal is not exported, it is defeated with 100% duty ratio while critical voltage V1 is risen to operating voltage V2 when thinking attraction axis
REM signal out, so that compared to existing situation the Connection Time can be shortened from the angle of control mode.
In addition, for making needed for the attended operation of clutch and axis " critical voltage V1 ", it is even identical from
Clutch also can be different because of load, place difference.If load is more and/or bigger, critical voltage V1 is also bigger.
For example, critical voltage V1 can be set as 10V for ADF registration roller (load is smaller)；For agent localization roller (load compared with
Greatly), critical voltage V1 can be set as 15V.
Simultaneously as the manufacturing condition of clutch is different and component has differences each other, so being even applied to same
The same part in one place, a possibility that changing there is also critical voltage V1.Therefore, to be not necessarily reduced to this critical
Voltage V1, it may be considered that given voltage is adjusted according to the requirement of user, i.e., is reduced, in a manner of the affluence having to a certain degree
Voltage value (designated value), controls required electric power according to the demand of user as a result, reaches effective control of energy consumption.For example, being directed to
Critical voltage can be set to be slightly less than 10V by ADF registration roller, for agent localization roller, critical voltage can be set to omit
Less than 15V.

One embodiment uses voltage-controlled method, does not have to concern EMI (electromagnetic interference: Electro-Magnetic
Interference), but circuit is complicated and be unfavorable for energy conservation.In contrast, second embodiment uses pulse controlled side
Method, circuit simply (without generating the circuit of the voltage value other than such as 24V) and is conducive to energy conservation, but worries EMI.It should say
It is bright, it is talked about if it is the equipment as MFP with battery, then on the contrary need not especially need to consider power saving.
For this purpose, in practical applications, however it is not limited to individually implement above two control method, it can be according to power supply device institute
Two kinds of control methods are applied in combination in the state (mode) at place.For example, control unit can lead to when power supply device is in standby
The service voltage for crossing opposite clutch supply is controlled and is switched between first state and the second state, is filled in power supply
It sets in sleep state (so-called sleep state is exactly the state that machine in-line power is cut off) or power save mode (so-called section comprehensively
Can state be main power source cutting inside machine state) when and the REM signal to control clutch controls the
It is switched between one state and the second state.So, control mode can be changed according to equipment state, selection is to pass through
Control service voltage still shortens the clutch Connection Time by pulse control REM signal, to play two kinds of controls comprehensively
The effect of mode.
In addition, as described above, the size of the duty ratio of critical voltage or REM signal be not it is fixed, can basis
The type of load is adjusted, i.e., in the second condition, determines to be intended to first state or become according to the type of load
To in the third state, for example, being more intended to the third state if voltage needed for driving load is lower.
Specifically, power supply device of the invention has receiving unit, the information about the second state is received from user,
Control unit is intended to first state according to the second state of information control about the second state or is intended to not drive completely
The state of load.As receiving unit, operation panel can have been enumerated.For example, when MFP is connect by network with various terminals,
Smart phone or PC become receiving unit.
