ABSTRACT:
A press machine comprises a holding plate provided with a number of receiving holes at constant arrangement pitches and a pin head having a number of press pins at the same arrangement pitches as the receiving holes. A portion provided with the receiving holes is in the form of a square, while a portion provided with the press pins is also in the form of a square, which has a width identical to that of the portion provided with the receiving holes and a depth half that of the portion provided with the receiving holes. The holding plate is placed on a movable table, which in turn is moved to a first working position to insert a first group of chip type electronic components into the receiving holes provided in a first half region of the holding plate by the press pins, and then moved to a second working position to press a second group of chip type electronic components into the receiving holes provided in a second half region of the holding plate by the press pins. Thus, it is possible to reduce a load applied to the holding plate as well as reactive force applied to the pin head in each pressing operation, while the pin head can be applied to various sizes of holding plates in common.
