ABSTRACT:
The present invention discloses a tape cassette having a front lid for protecting a magnetic surface of a magnetic tape accommodated in a casing made of upper and lower half members against dust or the like and a rear lid for protecting the back surface of the magnetic tape. The front lid is rotatably supported at sides of the casing. The rear lid is rotatably suspended on a connecting lever which is rotatably supported on the front lid. The magnetic tape is protected between the front and rear lids in a lid closed state. A pair of pins provided on the rear lid is snugly fitted in a pair of guide grooves formed in projections provided in the lower half member so that the rear lid may move in opening and closing directions. The guide grooves have open tops so that the pins of the rear lid are easily inserted into the guide grooves in the assembly process. The open tops are covered with front rims provided on the upper half member in the assembly process.
