検出装置。[Scope of Claim for Utility Model Registration] (1) In a tape recorder in which a cassette tape having a take-up reel and a delivery reel is mounted in a cassette tape storage part, an optical transmitting/receiving element consisting of a light emitting element and a light receiving element, and light reception by the above light receiving element. A detector comprising a detection circuit for detecting the presence or absence of Light from the light emitting element is transmitted to a position facing near the end of the tape of the feed reel on the top surface of the window only when the remaining amount of tape on the feed reel is below a predetermined value, and is reflected on the lower surface of the cassette storage section. A device for detecting the vicinity of a tape end of a tape recorder, characterized in that the light receiving element is arranged to receive light. (2) The optical transmitting/receiving element detects the vicinity of the tape end of the tape recorder according to claim 1, which is attached with an adhesive to the top surface of the transparent cover of the tape storage section or the top surface of the cassette tape transparent window. Device. (3) The optical transmitting/receiving element is located near the end of the tape of the tape recorder according to claim 1, which is attached to the upper surface of the transparent cover of the tape storage section or the upper surface of the transparent window of the cassette tape using a vacuum suction tool. Detection device.
