Abstract

PURPOSE: To improve detection precision by providing a gear which turns while a take-up side reel axis is turning.
CONSTITUTION: On slide plate 17, support axis 19 is provided to support gear 18, spring 20 and rotation detection piece 21. Consequently, moving pinch-roller change plate 11 as shown by (a) or (b) moves slide plate 17 in direction (a) or (b) through transmission plate 22, allowing gear 18 to engage with gear 15 or 16 of reel axis 13 or 14. Therefore, while reel axis 14 is turning to take up a tape, engaging gear 18 with gear 16 turns rotation detection piece 21 through the rotation of gear 18 to ratate stopper 23, and consequently switch driving plate 26 is rotated in the opposite direction to arrow S to disengage cam 25 from cam part 291. Once reel axis 14 stops, stopper 23 also stops and switch driving plate 26 is driven by cam 25 to turn tape-end detection switch 30 ON, so that if the tape would be caught by the capstan or pinch roller, tape-end detection woll be in effect.
