Claims

[Claims for Utility Model Registration] A tape cassette inserted from a cassette insertion slot is stored in a cassette holder, and the cassette holder moves between a cassette insertion position and a tape rotation position to load the tape cassette. In the cassette loading mechanism, an opening/closing door for opening and closing the cassette insertion opening is rotatably mounted, and an elastic member is used so that the opening/closing door always closes the cassette insertion opening, and a side of the opening/closing door. An engaging portion is formed in the cassette holder, and a portion of the cassette holder moved to the cassette insertion position engages with the engaging portion of the opening/closing door to rotate the opening/closing door and open the cassette insertion slot. A cassette loading mechanism characterized by having the following configuration.
