Filed: 2002-03-19
Abstract: <P>PROBLEM TO BE SOLVED: To easily cancel an energy saving mode of an image forming apparatus and shift to a standby mode without requiring operation of a console panel.  <P>SOLUTION: A vibration sensor 7 mounted on the apparatus is connected to a control part 4. In an ordinary standby mode and operation modes, switches 2 and 3 are in ON positions and power is supplied to all the circuits. Power is always supplied to the control part 4 regardless of the modes. When the apparatus shifts to the energy saving mode, the control part puts the switches 2 and 3 into OFF positions in order to interrupt the supply of power to the operation part 5 for outputs a and b of a converter 1 and a controller board C, etc. In the energy saving mode, when a user lightly pats the apparatus, the vibration sensor 7 detects the vibration and the control parts 4 puts the switches 2 and 3 into ON positions in response to it, thereby re-supplying power. Consequently, the apparatus cancels the energy saving mode and shifts to the standby mode.  <P>COPYRIGHT: (C)2004,JPO
