<p>PURPOSE:To make a device small-sized and lightweight by performing brake operation, idler switching, and cassette loading operation in accordance with each mode by a moving means. CONSTITUTION:A link 87 is turned to guide pins 91 and 92 along long holes 93 and 94, and a link 90 is moved left against the elastic force of a spring 99 and a pin 96 provided on the link 90 is moved left to press a link 100, and thereby, the link 100 is turned clockwise around a supporting shaft 103 against the elastic force of a spring 102 to separate brake shoes 108 and 110 from side faces 107 and 109. A pin 97 is moved left also to disengage the pin 97 from a link 125. A pin 115 is slided on a cam 285 of the link 90, and a link 111 is turned counterclockwise around a supporting shaft 114 by the elastic force of a spring 113, and a link 116 is turned clockwise around a supporting shaft 117, and an idler 119 is pressed to a rotating body 172 through a link 118.</p> |
