PURPOSE: A tape-loading device is provided to decrease the number of parts by a spring to a loading drive gear within and to easily perform assembling by simplifying the structure. CONSTITUTION: A tape-loading device comprises a loading drive gear(58); a pair of tape guides; coupling members(72,73) for coupling the loading drive gear and tape guides; and a pair of loading stoppers for stopping the tape guides at the loading terminating position. The loading drive gear rotates about a shaft. The loading drive gear includes a U-shaped groove in which the shaft is disposed and a spring accommodating portion disposed continuously to the U-shaped groove. The first and second arms(60,61) are rotated by the rotation of the loading drive gear. Sliders(3,4) are moved along guide openings to wind a tape around a drum. When the tape has been loaded, the sliders are stopped by catchers(17,18). When the loading drive gear is further rotated, the shaft is moved to the spring accommodating portion, and an energizing force is generated to a spring(81) and exerted on the first and second arms in a direction where the sliders are pressed against the catchers. Therefore, the positions of the sliders are fixed so that the tape stably travels. Since the spring is contained in the loading drive gear, the number of parts is reduced as well as the tape loading device is arranged simply and assembled easily.
