PURPOSE: To obain the captioned equipment which can correspond to high speed operation, and perform correct and reliable movement in such a way that a cam is directly brought into close contact and held by means of two rollers which are pivotally installed on the moving dody, and a jig which is installed on the moving body is moved through the rollers by means of responsive movement of the cam.

CONSTITUTION: Two rollers 35 are installed on the adjusting plate 30 which provides a notch 34 on one side, and a cam 36 is brought into close contact and held by means of two rollers 35 through adjustment of an adjusting screw 33. Movement of the cam 36 is transferred through a roller 35 to moving body 26, and a jig 29 is moved along guides 23a, 23b. Thus, the roller 35 dispenses with the spring, etc. which energizes the cam 36, and movement of the cam can be correctly and reliably transferred.
