<p>PURPOSE:To prolong the life of a motor for driving a cam which operates a link mechanism and to rotate the cam smoothly by providing the cam with a looped endless path, and rotating the cam in one specific direction by a driving source and loading and unloading a cassette. CONSTITUTION:When a cassette tape 96 is inserted as shown by an arrow 106, the tip engagement part 108 of a slide piece 92 engages the reel hole 107 of the cassette tape 96 on the insertion side. Then, when the cam 27 which moves the cassette horizontally and a head base backward is rotated by a planetary gear device 35, the cassette horizontal rocking link 64 under the guidance of a specific looped cam gear formed on the surface of the cam 47 eccentrically with the rotational center axis of the cam 47 and its movement is amplified by an arcuate amplifying gear 83 and transmitted to a horizontal coupling link 84. Then, the horizontal coupling link 84 rotates as shown by an arrow 111 to slide the slide piece 92. Thus, the cassette tape 96 is put in a cassette holder 101.</p> |
