Tape cassette loading system.

摘要

A tape cassette loading system of a magnetic recording and reproducing apparatus comprises a cassette tray (16) adapted for holding a standard size tape cassette and having a depression (30) adapted for holding a compact size tape cassette, a cassette carriage (14) for transporting the cassette tray in a horizontal direction from an unloading position (P0) to the inside (P1) of the magnetic recording and reproducing apparatus, and an elevating mechanism (17) for moving the cassette tray transported to the inside of the magnetic recording and reproducing apparatus in a downward direction to a loading position (P3) where the tape cassette is located ready for loading on a rotary drum assembly of the apparatus. The loading system comprises detecting switches (60, 61, 73a, 74a) for detecting uncorrect state of the tape cassette on the cassette tray and a controller (53) for inhibiting the continuation of loading procedure when it is detected that the tape cassette is not properly or correctly placed on the cassette tray. The lock of the lid of the tape cassette is released when the tape cassette is lowered to the loading position and the lid is opened by engagement with a lid opening mechanism.
