CONTROLLER FOR CARRYING AND EJECTING MERCHANDISE OF AUTOMATIC VENDING MACHINE

摘要

PROBLEM TO BE SOLVED: To make in common the control circuit of an ejection mechanism having an alternating current load and a direct current load. SOLUTION: This control circuit is provided with first switches 415 and 416 for connecting or disconnecting solenoids 404 to 407 and an alternating current drive voltage, second switches 418 and 419 for connecting or disconnecting direct current motors 408 to 411 and a direct current drive voltage, a first coil 417 that operates so as to make the first switches 415 and 416 connect the solenoids 404 to 407 and the alternating current drive voltage in response to the direct current drive voltage while the second witches 418 and 419 disconnect the direct current motors 408 to 411 and the direct current drive voltage, and a second coil 420 that operates so as to make the second switches 418 and 419 connect the direct current motors 408 to 411 and the direct current drive voltage in response to the alternating current drive voltage while the first switches 415 and 416 disconnect the solenoids 404 to 407 and the alternating current drive voltage.
