<p>PURPOSE:To reduce the number of components, to simplify a structure and to reduce a cost by providing first and second guides for guiding a slider to the end of first or second linear part when the slider is moved from a first cam groove to a semicircular end of a second cam groove. CONSTITUTION:When a shaft 2 is rotatably driven by a driver 1, a first cam plate 5 is moved. In this case, when a slider 9 is disposed on a semicircle 8a of a second cam groove 8 of a second cam plate, it moves along the semicircle 8a of the groove 8 of the second plate 7 to rotate a rotary table 3. When the slider 9 is disposed at the end of the semicircle 8a of the groove 8 of the plate 7, the slider 9 moves along a long hole 3a of the table 3, the table 3 is not rotated, and a slider table 9 is moved in a direction of the shaft, 2 upon move ment of the slider 9 in a direction of the shaft. Thus, the number of components is reduced, structure is simplified, and a cost can be reduced.</p> |
