TOOTHED GEAR TRANSFER MECHANISM AND MAGNETIC TAPE TRAVEL MOTION HEIGHT CONTROL DEVICE TO WHICH TOOTHED GEAR TRANSFER MECHANISM IS APPLIED

摘要

PROBLEM TO BE SOLVED: To prevent impingement of each addendum part of both toothed gears, upon engagement of a driven gear which is engageable/disengageable as against a driving gear which rotationally drives by means of driving source.;SOLUTION: In a toothed gear transfer mechanism comprising the driving gear 47 which performs rotational drive by means of driving source 4 and the driven gear 22 which is arranged engageably and disengageably as against the driving gear 47 and is driven when it is engaged with the driving gear 47, the toothed gear transfer mechanism provided is characterized in that the addendum part 47a of the driving gear 47 and the addendum 22a of the driven gear are magnetized in the same magnetism.;COPYRIGHT: (C)2002,JPO
