Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
A tape cassette brake mechanism having a supply and a take-up reel of a tape cassette comprising: a half-case having a side wall; a resilient plate member which comprises at least one flat part and first and second bent parts connected to said flat part, said flat part contacting said side wall of said half-case; and, first and second brake members mounted on said half-case, said first and second bent parts respectively contacting said first and second brake members for selectively applying braking force to said reels wherein the resilient palte includes two flat parts at both sides and the two flat parts are contacted with said side wall of said half-case.
Claim 2
Dependent Claim
112 words
A tape cassette brake mechanism having a supply and a take-up reel of a tape cassette comprising: a half-case having a side wall; a resilient plate member which comprises at least one flat part and first and second bent parts connected to said flat part, said flat part contacting said side wall of said half-case; and, first and second brake members mounted on said half-case, said first and second bent parts respectively contacting said first and second brake members for selectively applying braking force to said reels wherein the resilient palte includes two flat parts at both sides and the two flat parts are contacted with said side wall of said half-case.
Claim 3
Dependent Claim
118 words
A tape cassette brake mechanism having a supply and a take-up reel of a tape cassette comprising: a half-case having a side wall; a resilient plate member which comprises at least one flat part and first and second bent parts connected to said flat part, said flat part contacting said side wall of said half-case; and, first and second brake members mounted on said half-case, said first and second bent parts respectively contacting said first and second brake members for selectively applying braking force to said reels wherein said first and second brake members include <-shaped arms and said first and second bent parts are respectively contacted with corresponding first and second <-shaped arms of the brake members.
Claim 4
Dependent Claim
118 words
A tape cassette brake mechanism having a supply and a take-up reel of a tape cassette comprising: a half-case having a side wall; a resilient plate member which comprises at least one flat part and first and second bent parts connected to said flat part, said flat part contacting said side wall of said half-case; and, first and second brake members mounted on said half-case, said first and second bent parts respectively contacting said first and second brake members for selectively applying braking force to said reels wherein said first and second brake members include <-shaped arms and said first and second bent parts are respectively contacted with corresponding first and second <-shaped arms of the brake members.
Claim 5
Dependent Claim
119 words
A tape cassette brake mechanism having a supply and a take-up reel of a tape cassette comprising: a half-case having a side wall; a resilient plate member which comprises at least one flat part and first and second bent parts connected to said flat part, said flat part contacting said side wall of said half-case; and, first and second brake members mounted on said half-case, said first and second bent parts respectively contacting said first and second brake members for selectively applying braking force to said reels wherein the first and second bent parts of the resilient plate comprise a half width part of the resilient plate formed by bending and the remaining half width part being flat shaped.
Claim 6
Dependent Claim
119 words
A tape cassette brake mechanism having a supply and a take-up reel of a tape cassette comprising: a half-case having a side wall; a resilient plate member which comprises at least one flat part and first and second bent parts connected to said flat part, said flat part contacting said side wall of said half-case; and, first and second brake members mounted on said half-case, said first and second bent parts respectively contacting said first and second brake members for selectively applying braking force to said reels wherein the first and second bent parts of the resilient plate comprise a half width part of the resilient plate formed by bending and the remaining half width part being flat shaped.
