ABSTRACT:
A tape cassette for use in a tape player includes a cassette case having a main portion with an external size which is substantially the same as that of the case of a different type of tape cassette and an additional portion which extends from one side of the main portion and has a thickness slightly smaller than that of the main portion. An information indicating portion is provided at a lower surface of the additional portion for indicating respective information by whether or not a hole is present at a predetermined position. An information reading member provided in the tape player for determining whether or not a hole is present at each respective predetermined position in the information indicating portion can be located at a position so as not to interfere with the cassette case of the different type of tape cassette. As a result, the information reading member will not hinder the loading operation of the different type of tape cassette into the tape player and the information reading member will not malfunction due to the loading of the different type of tape cassette.
