Title: Modulating apparatus
Inventor: OHARA KENJI
IPC: G11B15/10
Filed: 1982-10-20
Granted: 1988-05-14
Abstract: The change-over mechanism of this tape deck requires relatively little energizing current for the activating electro-magnet. This is achieved by using a magnetic-field switch in the form of moving armatures.  The core of an electro-magnet has two pairs of poles.  A magnetic cam on a gear wheel forms one armature.  When the unit is energized, the cam and wheel rotate in the field and the wheel engages with the rotating cog (6).  This has the effect of moving the tape head into the operating position via a level and sliding plate. Poles are bridged via level thus weakening the magnetic force which rotated the cam.  This facilitates reverse action.
