PURPOSE:To attain the micro adjustment of positional relation between each reproducing position of a reproducing head and each track position by composing the titled device of a belt winding reel, a pulling belt, a reproducing head moving means, a belt by-passing means, and a by-pass distance adjusting means. CONSTITUTION:When a dial 2 is rotated, the winding length of the pulling belt 18 by the belt winding reel through a sector wheel 15 is changed each prescribed length by the action of a latchet 3 and a pawl 7. Subsequently, a driving arm 20 compled with a pin 21 is also rotated and the reproducing head is moved every twice the arrangement interval between tracks along the centering direction of a tracking disc. Turning an operation shaft 51 of a tracking means 44 moves an arm 53 horizontally through a cam 53 and moves also the driving arm 20. The rotation of the operation shaft 51 makes it possible to execute micro adjustment of the positional relation between each reproducing position f the reproducing head and each track position in the range of about twice the arrangement interval of tracks. |
