PURPOSE:To make a motor compact and smooth and ensure the starting of a storage equipment for crushed ice or the like, by providing a scrape-off means driver with a clutch to connect the driver to the motor when it has reached prescribed rotational frequency. CONSTITUTION:When a motor 22 is started, it is rotated backward for a time set by a backward rotation time setting timer T1. After that, a delay by a time set by a forward rotation delaying timer T2 is effected, then turning the motor 2 forward. At that time, a clutch C1 remains disengaged. The clutch has such a construction that a secured boss and a rotatable wheel can be rotated relative to each other within a prescribed range of angle because of a stop pin and a slit until the motor 22 reaches prescribed rotational frequency. When the motor 22 is accelerated to the prescribed rotational frequency, the clutch C1 is engaged to connect the motor to a shaft 14 to rotate scrape-off blades 16 through a control section 20 and a geared motor 19 so that crushed ice is discharged. According to this constitution, the motor 22 is made compact and starting action is smoothed and ensured. |
