機構。 The PG mechanism of a magnetic sheet recording/reproducing device such as a video floppy is composed of a PG bobbin with a conductor wound around it, an iron core, a compression spring, and an angle that fixes the PG bobbin. The PG adjustment mechanism is characterized in that the iron core and the PG bobbin are fixed by the tap, and the PG bobbin is crimped to the angle by the force of a compression spring inserted into the iron core.
