第１項記載のカセツトテーププレーヤの磁気テー
プ巻き取りミス検出装置。[Scope of Claim for Utility Model Registration] (1) In a cassette tape player such as a rotating head type configured to perform recording, playback, etc. by pulling out a magnetic tape from inside the cassette half,
A signal generator that generates a pulse signal according to the number of rotations of the reel, a tape remaining amount calculation means that calculates the remaining amount of tape based on the pulse signal of the signal generator, and a tape remaining amount calculation means that reads the pulse signal and the information signal of the remaining tape amount. and a reading means, which compares the number of pulses counted when winding the magnetic tape with the number of pulses corresponding to the remaining amount of the tape, and determines whether or not the magnetic tape is completely wound into the cassette half when the magnetic tape is pulled out. 1. A magnetic tape winding error detection device for a cassette tape player, characterized in that it is configured to detect. (2) When the remaining tape amount calculating means is in a state where it cannot calculate the remaining amount of tape, it compares the number of pulses when pulling out the magnetic tape counted during tape loading with the number of pulses when winding the tape, and calculates the remaining amount of tape. A magnetic tape winding error in a cassette tape player according to claim 1, characterized in that the magnetic tape is configured to detect whether or not it is completely wound into a cassette half when the magnetic tape is wound. Detection device.
