Abstract
PURPOSE:To simplify operation of assembling and maintenance by a simple structure wherein the distance between an identifying element provided on a carriage surface and an identifying element provided on a cassette surface is changed in accordance with the variety of the type wheel in the cassette. CONSTITUTION:When the carriage moves toward a platen from right to left at a fixed speed V, a magnetic element 7 detects the 2nd permanent magnet 3' first and thn the 1st permanent magnet 3 and outputs two pulses P1, P2. By supervising the time internal t between these two detected pulses P1 and P2, the distance L between two permanent magnets 3 and 3' is obtained from vXt. Since the distance between two permanent magnets is set to the predetermined values L,L',L''... in accordance with the variety of the wheel, it becomes possible to identify the variety of the type wheel automatically by supervising the time between said two detected pulses P1 and P2.
