ABSTRACT:
A tape supplying and taking up apparatus is capable of use with either large or small size tape cassettes containing reels which can be of different diameters and rotated with a high degree of accuracy by reel spindles of simple structure. Each tape cassette for use with the apparatus has a shutter of the slide type for closing access holes in the bottom wall of the cassette casing.
Each of the reel spindles has a large size cassette receiving portion for receiving a tape reel of a large size tape cassette coaxial with a small size cassette receiving portion for receiving a tape reel of a small size tape cassette. The small size cassette receiving portion is smaller in diameter and disposed at a higher position than the large size cassette receiving portion. The diameter of a lower end of a reel spindle engaging hole provided in each reel hub of the small tape cassette is smaller than the outer diameter of the small size cassette receiving portion of the reel spindle. The reel spindle engaging hole of the large size tape cassette has, at a lower end portion thereof, an escape portion which is greater in diameter than the outer diameter of the small size cassette receiving portion of the reel spindle but smaller than the outer diameter of the large size cassette receiving portion and such escape portion is higher than the height of the small size tape receiving portion.
