ABSTRACT:
Tape cassettes, particularly video tape cassettes, are provided with means internally to count the number of times the cassette is subjected to a sequence of user operations. This enables a hirer of such cassettes to see how many times the cassette has been used and to charge a hire fee accordingly. The counter may be mechanical, electro-mechanical or electronic, and is actuated by means associated with the tape release mechanism already built into such cassettes as a standard component; thus, no modification to of extra interaction with, the cassette player is needed.
