<p><P>PROBLEM TO BE SOLVED: To make stabilized tape loading by moving the pole up and down corresponding to the kind of the tape cassette even if a tape cassette of a different tape width is inserted. <P>SOLUTION: The pole up/down mechanism 280 keeps the loading lift stage 289 in contact with the undersurface of the sub-chassis 440 when a spiral cam 291 turns to move the lift 285 up, and the arm 420a of a leaf spring 420 is pressed by the support 285d of the lift 285 and elastically deformed. Thus, the U groove 288 on the back edge of the lift 285 comes in contact with the flange 307b projecting on the stopper 307. Accordingly, the loading lift stage 289 is pushed by the leaf spring 420 and maintained in a state that its front end is pressed in close contact with the undersurface of the sub-chassis 440 with its rear end retained by the lift 285. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
