Tape cassette.

摘要

A tape cassette which is adapted to embody a number of bit patterns in its main body for representing cassette information including tape type information in the cassette. An original pattern to embody a bit pattern is a hole perforated in the wall of the cassette with a block member to close the opening of the hole, and by selective removal of the block member a bit pattern is obtained. For the purpose of smooth and correct punch out of the block member from the main body, a notch (32) is provided through the peripheral of the block member on a selected surface of the connect member corresponding to the punching direction. <IMAGE>
