Abstract: A tape cassette loading device in a tape recorder has an improved structure for smooth insertion of a cassette without resistance from a plate spring. The loading device includes plate spring members fixed at left and right sides of a holder, and a chassis installed on the upper part of the holder and having cam portions engaged with the plate spring members. When the holder is at an inserting position of the cassette, the plate spring members do not engage with the cam portions. Therefore, when the cassette is initially inserted into the holder, the cassette can be inserted into the holder without any resistance from the plate spring members.
