Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
81 words
An information-indicating recording tape reel, said reel comprising, in combination, a hub, at least one tape-retaining flange extending from said hub, detecting means for detecting information regarding a relative position of tape on said reel, electrical encoding means mounted on said reel for encoding said information into electrical signals, and optical means responsive to said electrical signals for providing a coded optical output of said information, said output being detectable from outside said reel by means for detecting said optical output.
Claim 2
Dependent Claim
81 words
An information-indicating recording tape reel, said reel comprising, in combination, a hub, at least one tape-retaining flange extending from said hub, detecting means for detecting information regarding a relative position of tape on said reel, electrical encoding means mounted on said reel for encoding said information into electrical signals, and optical means responsive to said electrical signals for providing a coded optical output of said information, said output being detectable from outside said reel by means for detecting said optical output.
Claim 3
Dependent Claim
43 words
A tape reel as in claim 1 in which said hub has a housing and including a storage battery in said housing for powering said detecting, encoding and optical means, and externally operable enabling means in said housing for enabling said optical means.
Claim 4
Dependent Claim
43 words
A tape reel as in claim 1 including a battery in said reel for energizing said detecting means, and means for periodically connecting said detecting means to said battery for only relatively short time intervals, with relatively long time periods between said intervals.
Claim 5
Dependent Claim
76 words
A tape reel as in claim 1 in which said reel is a video tape reel, and including sensor means for detecting each time when the tape has played for substantially one full play of a program recorded on said tape and creating a corresponding output signal, means in said hub for counting and storing such output signals over a period of time, and for delivering a signal representing a total count to said encoding means.
Claim 6
Dependent Claim
31 words
A tape reel as in claim 4 including a battery and means for intermittently connecting said counting means to be energized by said battery, said storing means comprising a non-volatile memory.
Claim 7
Dependent Claim
17 words
A tape reel as in claim 4 including a micro-controller programmed for use as said encoding means.
Claim 8
Dependent Claim
81 words
A tape reel as in claim 1 in which said reel has a pair of opposed flanges, and in which said detecting means comprises at least one sensor consisting of a radiation emitter and detector which are relatively flat, thin, planar devices mounted side-by-side in one of the flanges of said tape reel, whereby said detector detects light emitted by said emitter and reflected from the other flange of said tape reel when it is not covered by a tape roll.
Claim 9
Dependent Claim
82 words
A tape reel as in claim 1 in which said hub has a housing with said optical means being located inside said housing with access means to permit the reading of said optical output outside of said housing, said optical means being located at the center of said hub and being symmetrical with respect to the rotational axis of said reel so as to be readable by a code-reading wand inserted into said hub regardless of the rotational orientation of said reel.
Claim 10
Dependent Claim
59 words
A tape reel as in claim 1 in which said encoding means is adapted to create a series of timed signals, said optical means is a radiation emitter, said timed signals being adapted to cause said emitter to emit radiation in a pattern simulating the pattern seen by a bar-code reading wand when passing over a printed bar code.
Claim 11
Dependent Claim
61 words
A tape reel as in claim 2 in which said enabling means includes a pressure-responsive member actautable by a tip of a bar-code reading wand, said member having a transparent receptacle for the tip of said wand, with said optical means being mounted closely adjacent said transparent receptacle, whereby pressure from said wand at the receptacle location actuates said enabling means.
Claim 12
Dependent Claim
73 words
A tape reel as in claim 8 in which said reel has a pair of flanges and a splined receptacle in said hub for receiving a splined driving member, said optical means and said encoding means being mounted on a printed circuit board mounted at one end of said receptacle, inset into the material of one of said flanges, with flat optical sensors and wiring being mounted on an extension of said board.
Claim 13
Dependent Claim
27 words
A tape reel as in claim 1 in which said optical means comprises means for changing the reflectivity of a surface in response to said electrical signals.
Claim 14
Dependent Claim
