Reciprocating-type electric shaver

An electric shaver, comprising:

• an electromagnetic linear actuator including a hollow cylindrical stator having an electromagnetic coil;
• a permanent magnet mounted in said hollow portion of said stator to divide said hollow portion into first and second recesses;
• first and second movable members, made of magnetizable material, mounted in said first and second recess, respectively;
• an alternating wave generator that drives said electric coil;
• and
• a cutting head including first and second blade members being mounted on said first and second movable members;
• wherein a magnetic field established by said permanent magnet and said coil when driven by said alternative wave generator will move said first and second movable members cyclically back and forth in said first and second recesses, a cycle of movement of said first movable member being 180.degree. out of phase with a cycle of movement of said second movable member such that any movement of said first movable member is in a direction opposite of said second movable member;
• wherein movement of said first and second movable members drives said first and second cutting blade members relative to each other to cut hair adjacent thereto.

An electric shaver, comprising:

• an electromagnetic linear actuator including a hollow cylindrical stator having an electromagnetic coil;
• a permanent magnet mounted in said hollow portion of said stator to divide said hollow portion into first and second recesses having substantially semicircular cross sections;
• first and second movable members, made of magnetizable material, and having substantially semicircular cross sections, being movably mounted in said first and second recesses, respectively;
• an alternating wave generator that drives said electric coil;
• and
• a cutting head including first and second blade members being mounted on said first and second movable members;
• wherein a magnetic field established by said permanent magnet and said coil when driven by said alternative wave generator will move said first and second movable members cyclically back and forth in said first and second recesses, a cycle of movement of said first movable member being 180.degree. out of phase with a cycle of movement of said second movable member such that any movement of said first movable member is in a direction opposite of said second movable member;
• and
• wherein movement of said first and second movable members drives said first and second blade members relative to each other to cut hair adjacent thereto.
