Title: Power unit and image processor
Inventor: YAMAMOTO KAZUMA
IPC: H01F19/04
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To reduce the energy loss in standby mode and to reduce the mount area of the unit and make the unit small-sized by using the power-off signal outputted from an engine controller to a printer even as a signal for frequency control. SOLUTION: When the engine controller(EC) 200 is placed in a standby state, An RLDR port goes down to Lo, so a Tr 301 and a relay 300 turn off and an Fchg port of a power control IC 4 goes down, so that the frequency of an IC 4 is slower than usual. At the same time, a VCH port is held at Lo, a Tr 153 is turned off, and a resistance 152 is not conducted to set a voltage Vcc1 to 6 V. Then, the EC 200 holds the VCHG port at Hi in a print state to turn on the Tr 153, make the resistance 152 conductive, and set Vcc1 to 24 V, and then holds the RLDR port at Hi to turn on the Tr 301 and relay 300. Consequently, a diode D turns on, the voltage at a point P rises, and the Fch port of the IC 4 goes up to Hi, so that the frequency is faster than that in sleep mode.
