<p>PURPOSE:To make small in size and make light in weight for the entire unit, by commonly using the unit board for the magnetic path constituting means for the electromagnetic coil. CONSTITUTION:The unit board 10 is constituted with the magnetic substance of soft iron, and the displacement lever 96 made of magnetic substance is rotatably provided at the rear side via the shaft 104 made of magnetic substance such as soft iron, and the electromagnetic coil 134 is located via the coil hold plate 702 of magnetic substance. Thus, electric current is applied to the electromagnetic coil 134, magnetic lines of force is produced in the magnetic loop 700, the displacement lever 96 is turned with electromagnetic suction force, it is latched with the differential rod 68 to regulate this movement, the pinion 88 is turned with the movement of the cam follower 58 with the rotation of the triangle cam 56, the pressing lever 36 is turned with the movement of the play rack 60, the pintch lever 30, winding lever 206 are sequentially turned, and the magnetic tape 12 is wound on the winding reel via the rubber idler 216.</p> |
