第１項記載のテープレコーダの巻込防止装置。[Scope of Claim for Utility Model Registration] (1) A running stop detection means for detecting the stop of tape running, and a tape running mechanical means that is controlled every time the stop of tape running is detected to change from forward to rewind, or An abnormality in which a tape recorder has reverse travel control means for restarting travel in the reverse direction from rewind to forward, and counts the number of reversals that occur within a certain arbitrary fixed time, and outputs an abnormality detection signal when a predetermined number of times is reached. A tape recorder comprising a detection means, wherein when the abnormality detection means detects an abnormality, the reverse running control means controls the tape running mechanical means to stop the rotation of the capstan and the reel stand. Entrapment prevention device. (2) The abnormality detection means includes a timing unit that measures the travel time each time in the forward direction and the rewind direction, and compares the travel time measured by the clock unit with a predetermined reference time, and determines that the travel time is normal when the time is long, and the time is short when it is short. A utility model characterized in that it includes: a running discrimination section that discriminates as a timed running; and an abnormality detection section that outputs an abnormality detection output when the running discrimination section determines that short-time running is performed once or a predetermined number of times in succession. An entanglement prevention device for a tape recorder according to claim 1.
