ABSTRACT:
A computerized video record rental system and method in which a video record unit such as a tape cassette is provided with an integral counting device for counting the number of times the record is played. Upon rental and return of the record, the counts are recorded in computer memory, together with an identification of the record unit, and the computer computes the rental fee due based on the net play count for the record unit. The preferred counting device in the video cassette uses caliper arms to detect the position of one of the tape rolls in the cassette at two points on opposite sides of the roll and drives a counter in proportion to changes in the distance between the points. This virtually immunizes the mechanism from false counts due to lateral shifting of the tape reels in the cassette housing during handling of the cassette of a cassette playing machine. An alternative is a hybrid system using a mechanical tape motion sensor and an integral electronic counter and memory, with an LED read-out in a form which is readable by a bar-code scanner. An all-electrical counting and bar-code readout device also is disclosed. The latter device is contained entirely in one of the tape reels in the cassette, thus making the invention easily usable with existing cassette structures.
