    • An ink ribbon cassette includes a cassette main body portion rotatably holding a supply core and a take-up core around which the end portions of an ink ribbon are wound and a ribbon guide portion extending to one side from the cassette main body portion and having on one side a ribbon slide contact surface, a ribbon turn-up portion formed at the forward end of the ribbon guide portion being formed by a rotatable roller member, whereby the frictional resistance of the ink ribbon turned up at the ribbon turn-up portion is reduced. Further, the main body portion includes a holder member having the ribbon guide portion and holding the supply core and the take-up core and a case member capable of holding the holder member by holding the supply core and the take-up core in such a way as to cover them from outside, whereby it is possible to provide an ink ribbon cassette which can be easily assembled.

    • A substrate holding apparatus for vertically holding a substrate to be exposed by radiation includes a substrate stage having a substrate holding surface for attracting a substrate. The substrate holding surface is divided into an inner peripheral portion and an outer peripheral portion by a groove formed in the substrate stage. A magnetic member is fitted into the groove of the substrate stage, and at least a magnetic unit is embedded in the magnetic member. The magnetic unit includes a permanent magnet and an electromagnet for eliminating a magnetic force of the permanent magnet when energized. Further, a moving device is provided for moving the magnetic member together with the magnetic unit in a direction of the depth of the groove between a first position in which the magnetic force of the permanent magnet is effective for the substrate on the substrate holding surface and a second position in which the magnetic force of the permanent magnet is ineffective for the substrate on the substrate holding surface. The electromagnet need not be energized during a substrate positioning period if the magnetic member with the magnetic unit is brought to the second position.
    • 用于垂直保持待曝光的基板的基板保持装置包括具有用于吸引基板的基板保持表面的基板台。 基板保持面通过在基板载台上形成的槽分为内周部和外周部。 磁性部件嵌入到基板台的槽中,并且至少磁性单元嵌入在磁性部件中。 磁性单元包括永磁体和用于消除永磁体在通电时的磁力的电磁体。 此外,提供一种移动装置,用于使磁性部件与磁性单元一起在凹槽的深度方向上移动,该第一位置在永久磁铁的磁力对基板保持表面上的基板有效的第一位置和 永磁体的磁力对基板保持面上的基板无效的第二位置。 如果将具有磁性单元的磁性构件带到第二位置,则在基板定位周期期间,电磁体不需要被通电。
