<p>PURPOSE:To enable a tape to be ejected at any time by generating a control signal which permits a tape drawing-out member to move where the cassette half of a magnetic tape is stored on the generation of an electric-feed stop detection signal. CONSTITUTION:An auxiliary power source capacitor 9 capable of supplying electric power for a long enough period at least to store a magnetic tape 34 in a cassette half 33 after the power supply of a main power source circuit 1 is stopped is provided connecting with the main power source circuit 1, and an electric-feed stop detecting circuit 13 is provided to detect the stop of the power supply of the main power source circuit 1. Further, reel shafts 35 and 36 are coupled with the reels 31 and 32 of a tape-drawn-out type cassette 30 constituted so that an information signal is recorded on a magnetic tape 34 stored in the cassette half 33 by being wound around the reels 31 and 32 and drawn out of the cassette half 33. Furthermore, reel turntables 37 and 38, and reel motors 39 and 40 are provided.</p> |
