PURPOSE:To improve operation with no restriction of switch operation by program- controlling the make and break of a power supply judging the depression state of an operation switch from the program. CONSTITUTION:Power-supply main body POW is connected to a power supply of AC 100V via contacts (ms1) and (ms2) of DC relay MS. With the contact of switch part SW made, DC relay MS starts operating and switch part SW operates by each switch equipped to operation part OP. Therefore, power is fed by making the contact of switch part SW and the holding of the power feed is done by holding circuit HLD. Then, program control part PG discriminates the state of each contact by the program corresponding to the feeding of power to indicate the power feeding to holding circuit HLD and also to indicate the cutting-off of the power supply corresponding to the completion of various operations. |
