PURPOSE: A strip pusher device of fabrication equipment for semiconductor package is provided to economize a fabricating cost by reducing the number of components and the size of the strip pusher device. CONSTITUTION: A drive portion(20) is installed at one side of a base plate(10). The drive portion(20) is formed with a step motor(21), a timing belt(22), a pulley(23), a driving roller(24), and a bearing(25). A rotary shaft of the driving roller(24) is combined with the base plate(10) by the bearing(25). An encoder portion(30) is installed at one side of the drive portion(20). The encoder portion(30) is formed with a roller(31), an encoder(32), a ball plunger(33), a bracket(34), and a bearing(35). The encoder(32) is used for sensing a rotating state of the roller(31). A plate spring is closely contacted between the driving roller(24) and the roller(31). A straight guide is installed at a side portion of the base plate(10).
