PURPOSE:To realize a miniature power source and ensure a quick input action, by supplying an input power source in time division to plural unit input circuits based on a command given from a controller. CONSTITUTION:The input power source 12 has the current capacity equivalent to a unit of the unit input circuits 10a-10d. The control part 16 supplies the power source 12 in time division to each unit input circuit 10 with a timing given from the timing generating part 13. On receiving a power supply from the source, each unit input circuit makes a voltage rise of input power source like waveform A. Thus a feed from an external contact is made possible. When the power source 12 is stabilized, the part 16 generates the timing B (waveform B) and sets the information C of the external contact to the register file 14. |
