PROBLEM TO BE SOLVED: To provide an automatic ice making machine capable of outputting an off-signal as a signal indicating that an ice moving mechanism is brought into a reference state while a contact part of a tact switch is prevented from being frosted.SOLUTION: An automatic ice making machine 1 includes an ice moving mechanism 10 which performs an ice moving operation to move ice on an ice tray 3 to an ice storage tank 2, and a signal output circuit 14 which outputs a reference signal indicating that the ice moving mechanism 10 is in a reference state, and makes ice when the ice moving mechanism 10 is in the reference state. The signal output circuit 14 includes a tact switch 17 pressed by the ice moving mechanism 10, and an inverting circuit 62 which inverts a signal from the tact switch 17, and is configured so that the tact switch 17 is pressed in the reference state. Consequently, a state that contact parts 17b, 17c of the tact switch 17 are closed is continued for a long time, and thereby, the contact parts 17b, 17c are prevented from being frosted. Furthermore, the inverting circuit 62 is included, and thereby outputting an off-signal in the reference state from the signal output circuit 14. |
