ANGULAR POSITION SELECTING AND CONTROLLING DEVICE FOR A ROTARY MEMBER

An angular position selecting and controlling device for a rotary member enabling to easily and arbitrarily pre-select a plural number of angular stopping positions of a rotary member by operating a button, and also enabling, by operation of another button, to stop the rotary member reliably with minimum power consumption successively at angular positions pre-selected as mentioned above, said angular position selecting and controlling device comprising a plurality of pins movably fitted along the circumference of the rotary member, two controlling levers for making those pins project from and push into the surface of the rotary member, an electromagnet having an armature which is capable of locking the rotary member at a stopped position, a stop lever engageable with the above-mentioned pins, a locking lever being engaged with said stop lever and being capable of holding the above-mentioned armature at a position where said armature is attracted by the electro-magnet, a switch for starting the rotary member by operation of the above-mentioned button and at the same time for energizing the electromagnet, and a switch for continuing the rotary motion of the rotary member being closed by the armature when said armature is attracted by the electro-magnet.
