ABSTRACT:
A tape end detecting device detects a tape end in a tape cassette comprising a cassette case. The cassette case comprises a first reel having a first reel hub and a second reel having a second reel hub, an opaque tape having first and second transparent leaders integrally fixed to the opposite ends thereof, wherein the tape is connected at the opposite ends of the leaders to the first and second reel hubs. The tape end detecting device comprises at least one light-emitting element, and at least one light-receiving element. The light-emitting element and the light-receiving element are arranged outside a tape cassette loading space for loading the tape cassette so that a traveling path of a light beam connecting the light-emitting element and the light-receiving element intersect the tape and the first or second leader. The light-receiving element receives the light beam which passes through the first or second leader when the first or second leader assumes a position intersecting the traveling path of the light beam connecting the light-emitting element and the light-receiving element, to detect a tape end at the first or second reel.
