PURPOSE:To obtain an intermittent rotating device, which can easily be manufactured and which can be miniaturized, by providing a cylindrical surface with an input shaft, which is equipped with a cam groove having a specific pattern including a stationary part, and an output shaft, which is equipped with a wheel surface having ball-bearings engaged with the cam groove, in such a manner that both input and output shafts are perpendicular to each other. CONSTITUTION:In an intermittent rotating mechanism incorporated in a housing having a shape of a rectangular parallelopiped is provided with a cam groove 4, which is formed in a cylindrical surface of an input shaft 3, and a wheel surface 51, which is formed in an output shaft 5, which is born in the direction perpendicular to the input shaft 3. In addition, ball bearings 6, which are incorporated in the upper surface of the wheel surface 51 in a freely rotatable manner and the number of which is three or more (e.g. four), are engaged with the cam groove 4. The cam groove 4 consists of a rotation driving part 41, which moves at a predetermined rate in the axial direction, and stationary parts 42, which are situated at the middle of the rotation driving parts 41 and at the same circumference, and the sectional form of the cam groove 4 is of a Gothic arch. With this contrivance, when the input shaft 3 is driven for rotation, the wheel 51 is rotated via the ball bearings 6 within the can groove 4. However, the rotation of the wheel 51 is intermittent owing to the presence of the stationary parts 42. |
