PURPOSE:To control a control plate at an accurate position referring to a guide plate when a cassette holder is moved to the position where a magnetic sheet can work, by attaching the control plate movably to the cassette holder. CONSTITUTION:A magnetic head 8 is set opposite to the lower position to a head protruding window part 16 which is formed to a guide plate 12 that stabilizes a contact between the head 8 and a magnetic sheet. A pair of height control pins 17 and 17 are planted on the plate 12. The tip part 23a of a fixed shaft 23 touches and hooks to a space control screw 26 attached at the tip of a control plate 19. The plate 12 is provided with a plate type horizontal part 27 and a block 28 formed at the base end of the part 27. A guide surface 27a is formed into smooth surface on the upper end surface of the part 27 to guide the magnetic sheet so as to make the sheet substantially parallel to the rotary surface. |
