PURPOSE:To rotate intermittently a driven rotational body even when a driving rotational body rotates ecceedingly 360 degrees in a Geneva mechanism suitable for a pulling-out mechanism for tape of a magnetic head recording device by forming a stopping circular arc surface which comes into the way of teeth portion of a driving body. CONSTITUTION:When a driving rotational body 1 is rotated clockwise, rotation of the rotational body 1 is not transmitted to a driven rotational body 2 while a lower claw piece 25 of the driven rotational body 2 is in a sliding contact to a stopping circular arc surface 15 of the rotational body 1, and the driven rotational body 2 is under a stopping condition. Then, lower stage teeth 12 of the rotational body 1 are meshed with lower stage teeth 22 of the driven rotational body 2. The driven rotational body 2 is rotated while upper stage teeth 14, 24 of the rotational bodies 1, 2 are disengaged from each other, following up the rotation of the rotational body 1. In case that an upper claw piece 26 of the driven rotational body 2 is in a sliding contact to the stopping circular arc surface 15 of the rotational body 1, the driven rotational body 2 is held in a stopping condition again. The driven rotational body 2 can be rotated intermittently even when the rotational body 1 is rotated over the degree of 360.
