ドの移動範囲検出装置。 An input/output device that has a recording head that is capable of reciprocating movement and records and reproduces information from a specific position on a recording medium, and a pair of sensors that detect both limit positions in the movement range of this recording head. A pair of pushing members are provided in the vicinity of the recording head, the rotating plate being always biased to a neutral position by a spring, and the rotating plate being rotated from the neutral position in the vicinity of both limit positions of the recording head. Detection of a moving range of a recording head in an input/output device, characterized in that the recording head is arranged to move in synchronization with the recording head, and the pair of sensors are arranged adjacent to each other in the vicinity of the rotating plate. Device.
