Abstract

Abstract A tape recorder is provided with a tape cartridge unit wherein a payout or supply reel and a takeup reel are mounted side-by-side on parallel-spaced axes. When the cartridge unit is in its operating position, the reels are in a plane adjacent to, and parallel to, the front of the tape recorder. A pressure roller presses the tape against a capstan which is mounted separately from the cartridge unit. A single spring provides this pressure and also holds the cartridge unit releasably in operating position and further operates a brake to inhibit movement of the reels when the cartridge unit is removed from its operating position. The tape is directed from the pressure roller to the inner sides of the reels.
