Amendment Showa 5 & IZ 16 The scope of claims for utility model registration is amended as follows. O Scope of Claims for Utility Model Registration A billet, at least a part of which is formed by a permanent magnet and is supported so as to make an impact motion toward the impacting part, is provided within an empty field of electromagnetic poles around which a coil is wound, and the permanent magnet is An electromagnetic operating mechanism characterized by being composed of plastic magnets. The brief description of the drawing has been amended as follows. The first digit "(in a magnetic field)" in No. 12Jj'' of the specification is deleted.

Claims

[Scope of utility model registration request]

A billet formed at least in part by a permanent magnet and supported for impact motion toward the striking part is provided within the magnetic field of an electromagnetic pole around which a coil is wound, and the permanent magnet is composed of a plastic magnet. An electromagnetic operating mechanism characterized by:
