<p>PURPOSE: To obtain a magnetic recording and reproducing device which can perform FF reproduction, FB reproduction, still reproduction, and time-lapse recording. CONSTITUTION: A drum shaft 14 which coaxially supports an upper drum 11 and lower drum 12 and a lead ring 17 which guides a magnetic tape when the ring 17 is fitted loose in the lower drum 12 are integrally supported on a drum base 18. In addition, a gear 42 interlocked with a screw 25a screwed in the ring 17 is attached to a shaft 40 in which a coupling gear 41 provided in the stepped hole 18a of the drum base 18 is press-fitted by meshing the gear section 25a1 of the screw 25a loose with the coupling gear 41 and supporting the shaft 40 by the base 18 in a rotatable state. Since the gear 42 is meshed with a driving gear 60, the meshing state between the screw 25a and gear 60 is improved.</p> |
