<p>PURPOSE:To prevent a cassette loading mechanism and a tape loading mechanism from being damaged due to erroneous insertion of a cassette by controlling their operations with a relative positioning change in the vertical direction between a cassette drawing lever and a cassette detecting lever that occurs at the time of engaging the cassette drawing lever with an operational recessed part on the upper surface of the cassette. CONSTITUTION:A drive for the cassette loading mechanism is fitted to a slide angle 11, which is turnably fitted with the cassette drawing lever 9, to be adjacent to the cassette detecting lever 10, and is controlled by utilizing the relative positioning change in the vertical direction between the cassette drawing lever 9 and the cassette detecting lever 10 that occurs at the time of engaging the cassette drawing lever 9 with the operational recessed part 58 on the upper surface of the cassette. Consequently, even when the cassette 1 is inserted into an insertion hole until a panel surface by erroneous insertion, the cassette drawing lever 9 is not engaged with the operational recessed part 58 on the upper surface of the cassette at all. By this method, the cassette loading mechanism to be driven is not operated by the relative movement between the cassette drawing lever 9 and the cassette detecting lever 10, thus preventing the mechanism from being damaged.</p> |
