Abstract
In a transfer apparatus in which a pallet is stationary when the crossing angle between the axes of rotation of a driven roller and a driving shaft is zero, and the pallet may be driven when the angle is greater than zero, a stop-start apparatus comprising a cam follower roller supported by a support member of said driven roller, a stopper block guided and supported at a stop position of the pallet so as to move to and fro in the directions of the transfer and having a notch into which said cam follower roller fits so as to keep said angle zero, a cam the proximal end of which is pivotally supported at a forward position of said stop position having a cam surface on which said cam follower roller makes a rolling contact, a spring urging said cam to a predetermined position, the distal end of said cam, in said predetermined position, being near said notch and said cam being so shaped as to increase said angle from zero to 45 degrees from said distal end toward the proximal end.
