Abstract
An apparatus for detecting a tape-end, according to the present invention, comprising, a tape cassette including a magnetic tape wound on reels received in the tape cassette, and tape-ends arranged between the reels and magnetic tape respectively so that the magnetic tape is connected to the reels through the tape-ends, a magnetic head drum on which the magnetic tape is loaded, a tape loading device which draws out the tape from the tape cassette and which loads the magnetic tape onto a head surface of the magnetic head drum, tape-end detectors for detecting the tape ends on tape paths between the magnetic head drum and the reels, and loading controlling means including a loading phase measuring instrument which measures a phase of the tape loading device during loading operation when at least one of the tape-end detectors detects the tape end, the loading controlling means generating control signals for controlling the loading operation of the tape loading device in accordance with the measured phase, so that the time required until the loading operation is completed is shortened in comparison with the prior art.
