Abstract

PURPOSE:To automate the application and break of a main power source and beam power source with a time difference by controlling main and subordinate switching elements and ON and OFF timers through a control switch. CONSTITUTION:With control switch Sc turned on, FF is set, and transistor Q1, relay RL1 and relay contact rl1 all turn on, so that common power source P1 and heater power source P2 will be connected to camera circuit CC. Simultaneously, ON timer TM1 is actuated and after a set time limit, transistor Q2, relay RL2 and relay contact rl2-1 turn on while relay contact rl2-2 turns off, connecting beam power source P3 to camera circuit CC. With control switch Sc turned off, relay RL2 turns off to disconnect beam power source P3. Simultaneously, relay contact rl2-2 turns on to actuate OFF timer TM2 with a differential pulse generated by capacitor C1 and a set time later, FF is reset while relay RL1 is turned off, disconnecting all power sources from camera CC.
