Abstract
A miniature type tape cassette comprises a spring for urging a lid having a first hook in a lid closed direction and a lid locking member like an elastic plate having a projecting part, a second hook and a rear part. The projecting part projects from a side wall of a cassette case through a through window formed in the side wall. The second hook engages with the first hook when the lid is in a closed state. The rear part is fitted into a supporting part of the side wall in the tape cassette, so that the lid locking member is fixed to the side wall of the cassette case. The release of lock of the lid is carried out by pressing the projecting part of the lid locking member.
