<p>PURPOSE:To surely transmit and disconnect power to each base corresponding to a switched mode by fitting reel brake plates for supply and take-up so as to freely rotate and energizing them in the direction pressing against each reel base. CONSTITUTION:The push part 293c of the supply reel brake plate 293 having a supply reel preload plate is fitted in the pin 294 of a main chassis 1. The plate 293 is freely rotatively fitted at the corresponding position of the gear part 302a of a supply reel base 302, and turned by a spring 295 between a hook part 293d and the hook part 215a of the chassis 1 in the direction pressing against the base 302. On the other hand, the push part 296c of the take-up reel brake plate 296 is fitted in the pin 297 of the chassis 1. The plate 296 is freely rotatively fitted at the corresponding position of the gear part 309a of a take-up reel base 309 pressing a take-up reel preload plate giving mean, and turned and rotated by a spring 298 between a hook part 296d and the hook plate 292 of the chassis 1 in the direction pressing against the base 309.</p> |
