摘要： A tape running system for a slide loading type magnetic recording and reproducing apparatus. The system comprises a stationary base plate mounted on a deck mechanism of the apparatus, a slide base mounted on the stationary base plate such that it is reciprocated with respect to the stationary base plate within a predetermined range, a pair of loading gears mounted on the lower surface of the stationary base plate and engaging with each other and connected to a pair of slant post assemblies through individual loading levers, and a rotational force transmitting unit transmitting the rotational force of the loading gears to the slide base for driving the slide base. The rotational force transmitting unit is connected between one of the pair of loading gears and the slide base and linearly reciprocates the slide base using the rotational force of the loading gears. The pair of slant post assemblies as well as the slide base are driven by the rotational force of the loading gears, thereby achieving the recent trend of compactness and light weight design.
