Abstract
A reel guide apparatus of a magnetic recording/reproducing apparatus accurately seats the supply reel and take-up reel onto a lower chassis of the apparatus. The reels are installed on a slider which is lowered to the lower chassis. Holes in the slider receive reel guide units for stably guiding the reels in the vertical direction. A position determining unit on the lower chassis accurately determines the seating of the tape cassette on the lower chassis. Sensors on the reel guide units and split disc reflectors on the reels facing the sensors result in the generation of reel pulses, which are used to determine remaining tape length, etc.
