Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
101 words
In a cassette for use with a recorder comprising, a. a cassette housing formed by walls, b. reel means in said cassette housing for holding magnetic tape thereon, c. a chassis having drive means located thereon and interconnecting with said reel means to drive the latter, d. a counter having indicia thereon mounted in said cassette adjacent one of said walls, e. a counter-actuating means linked to said drive means whereby rotation of said reel means a predetermined amount of time serves to intermittently actuate the counter-actuating means which thereby gives an indication of the time the magnetic tape was used.
Claim 2
Dependent Claim
101 words
In a cassette for use with a recorder comprising, a. a cassette housing formed by walls, b. reel means in said cassette housing for holding magnetic tape thereon, c. a chassis having drive means located thereon and interconnecting with said reel means to drive the latter, d. a counter having indicia thereon mounted in said cassette adjacent one of said walls, e. a counter-actuating means linked to said drive means whereby rotation of said reel means a predetermined amount of time serves to intermittently actuate the counter-actuating means which thereby gives an indication of the time the magnetic tape was used.
Claim 3
Dependent Claim
49 words
In a cassette for use with a recorder as defined in claim 1 in which the drive means on the chassis includes a shaft extending into the cassette through an opening formed therein and into engagement with said reel means and said counter-actuating means is linked to said shaft.
Claim 4
Dependent Claim
61 words
In a cassette for use with a recorder as defined in claim 1 in which the counter-actuating means comprises a member mounted for movement within said cassette and adjacent the counter to abut against the counter and motion-transmitting means within the chassis adapted to selectively actuate the member mounted for movement in the cassette after a predetermined period of elapsed time.
Claim 5
Dependent Claim
30 words
In a cassette for use with a recorder as defined in claim 3 in which the counter-actuating means comprises a lever pivotally mounted adjacent said counter within said cassette housing.
Claim 6
Dependent Claim
93 words
In a cassette for use with a recorder as defined in claim 3 in which the motion transmitting means comprises a gear member in said chassis operatively connected to said drive means, said gear member connected to a movable member, said movable member having means thereon which abuts against a resiliently biased plunger having a portion thereof extending into said cassette through an opening formed therein and abuts against said member mounted for movement within the cassette to selectively move said member and thereby actuate the counter after a predetermined lapse of time.
Claim 7
Dependent Claim
31 words
In a cassette for use with a recorder as defined in claim 5 further comprising a clutch mounted on said chassis which selectively connects the drive means to the gear member.
Claim 8
Dependent Claim
46 words
In a cassette for use with a recorder as defined in claim 5 in which said movable member and said gear member are interconnected in a timed relationship whereby the movable member moves a predetermined distance after a predetermined number of revolutions of said reel means.
Claim 9
Dependent Claim
31 words
In a cassette for use with a recorder as defined in claim 1 further comprising a clutch mounted on said chassis which selectively connects the drive means to the counter-actuating means.
Claim 10
Dependent Claim
41 words
In a cassette for use with a recorder as defined in claim 1 in which said one wall has an opening formed therein for viewing said indicia whereby a user is informed of the time which the magnetic tape was used.
Claim 11
Dependent Claim
32 words
In a cassette for use with a recorder as defined in claim 1 further comprising a stop means operative connected to said counter to preclude movement of the counter in one direction.
