As shown in figure 5, in the case where being not desired to axis of the driving as load, control unit is supplied to the clutch as interconnecting piece
(i.e., axis attract and the voltage of the critical condition without attraction, in other words, right to preset critical voltage V1
The voltage for the critical condition that axis will be attracted) and REM signals are not exported, at the connection status to make 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 signals more) and with 100% duty ratio are exported, to make the connection status of clutch and axis from the second state to first

Shorten the clutch Connection Time without additional component, productivity is improved while not improving component costs.
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 signals are not exported, it is defeated with 100% duty ratio while wanting that critical voltage V1 is risen to operating voltage V2 by the when of attracting axis
Go out REM signals, to which compared to existing situation the Connection Time can be shortened from the angle of control mode.
In addition, for " critical voltage V1 " needed for the attended operation for making clutch and axis, 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, for ADF registration rollers (load is smaller), critical voltage V1 can be set as 10V；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

Interference), but circuit is complicated and be unfavorable for energy saving.In contrast, second embodiment uses pulse controlled side
Method, circuit simple (without generating the circuit of the voltage value other than such as 24V) and conducive to energy saving, but worry EMI.It should say
It is bright, it is talked about if it is the equipment with accumulator as MFP, 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 supply unit institute
Two kinds of control methods are applied in combination in the state (pattern) at place.For example, control unit can lead to when supply unit 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 and is in sleep state (so-called sleep state is exactly the state that machine in-line power is cut off comprehensively) or power save mode (so-called section
Can state be main power source cut-out inside machine state) when by controlling the REM signals for controlling clutch 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 Width Control REM signals, 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 signals is not fixed, it can basis
The type of load is adjusted, i.e., in the second condition, is determined to be intended to first state according to the type of load or be become
To in the third state, if for example, the voltage needed for driving load is lower, more it is intended to the third state.
Specifically, the supply unit of the present invention has receiving part, 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 part, operation panel can have been enumerated.For example, when MFP is connect by network with various terminals,
Smart mobile phone or PC become receiving part.
In addition, for the concrete application of above-mentioned first embodiment and second embodiment, lifts ADF and (remove automatically
Send device：Automatic Direction Feeder) it illustrates for registration roller, in the first state, positioned using ADF
