Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
70 words
An ink film cassette which is detachably attached to a thermal transfer recording device, comprising: a supply reel winding an ink film therearound; a take-up reel which rolls up the ink film fed out from said supply reel; a frame accommodating said supply reel and said take-up reel; and a torque apply means provided between said supply reel and said frame so as to apply torque to said supply reel.
Claim 2
Dependent Claim
70 words
An ink film cassette which is detachably attached to a thermal transfer recording device, comprising: a supply reel winding an ink film therearound; a take-up reel which rolls up the ink film fed out from said supply reel; a frame accommodating said supply reel and said take-up reel; and a torque apply means provided between said supply reel and said frame so as to apply torque to said supply reel.
Claim 3
Dependent Claim
29 words
The ink film cassette as claimed in claim 1, wherein said torque apply means is a torque limiter which is provided on an end portion of said supply reel.
Claim 4
Dependent Claim
48 words
The ink film cassette as claimed in claim 2 wherein said torque limiter includes a plate member engaged with said of the, at least one friction plate and a coil which are provided on a shaft of the supply reel at an end portion of the supply reel.
Claim 5
Dependent Claim
38 words
The ink film cassette as claimed in claim 1, wherein said torque apply means includes sponges adhering on an interior surface of the cassette so as to rub an exterior surface of a shaft of said supply reel.
Claim 6
Dependent Claim
23 words
The ink film cassette as claimed in claim 1 further comprising a breaking means which applies a breaking force to the take-up reel.
Claim 7
Dependent Claim
39 words
The ink film cassette as claimed in claim 5 wherein said breaking means applies the breaking force by setting a clearance between a shaft of the take-up reel and a bearing which supports the shaft to a predetermined size.
Claim 8
Dependent Claim
49 words
The ink film cassette as claimed in claim 1 further comprising a second torque limiter which transmits to said take-up reel driving force generated by a driving section provided in a body of the thermal transfer recording device therethrough so as to limit driving torque of said take-up reel.
Claim 9
Dependent Claim
40 words
The ink film cassette as claimed in claim 7, wherein the value of torque applied to the supply reel by said torque apply means is set to be greater than the value of torque limited by said second torque limiter.
Claim 10
Dependent Claim
36 words
The ink film cassette as claimed in claim 1 further comprising a rewinding member provided on the supply reel and rewinding an ink film which is fed out from the supply reel to the supply reel.
Claim 11
Dependent Claim
47 words
The ink film cassette as claimed in claim 9, wherein said rewinding member is a spring member, one end of the spring member being attached to the supply reel and the other end of the spring member being attached to a plate member engaged with said frame.
Claim 12
Dependent Claim
55 words
The ink film cassette as claimed in claim 1, wherein a part of said frame in which the take-up reel is incorporated and a part of said frame in which the supply reel is incorporated are circular in cross-section, and the outside diameter of the former is larger than the outside diameter of the latter.
Claim 13
Dependent Claim
98 words
An ink film cassette which is detachably attached to a thermal transfer recording device, comprising: a supply reel winding an ink film therearound; a take-up reel which rolls up the ink film fed out from said supply reel; a frame accommodating said supply reel and said take-up reel; a first torque limiter provided between said supply reel and said frame so as to apply torque to said supply reel; and a second torque limiter which transmits to said take-up reel driving force generated by a driving section provided in a body of the thermal transfer recording device therethrough.
Claim 14
Dependent Claim
98 words
An ink film cassette which is detachably attached to a thermal transfer recording device, comprising: a supply reel winding an ink film therearound; a take-up reel which rolls up the ink film fed out from said supply reel; a frame accommodating said supply reel and said take-up reel; a first torque limiter provided between said supply reel and said frame so as to apply torque to said supply reel; and a second torque limiter which transmits to said take-up reel driving force generated by a driving section provided in a body of the thermal transfer recording device therethrough.
Claim 15
Dependent Claim
23 words
The ink film cassette as claimed in claim 12 further comprising a breaking means which applies a breaking force to the take-up reel.
Claim 16
Dependent Claim
36 words
The ink film cassette as claimed in claim 12 further comprising a rewinding member provided on the supply reel and rewinding an ink film which is fed out from the supply reel to the supply reel.
Claim 17
Dependent Claim
70 words
An ink film cassette which is detachably attached to a thermal transfer recording device, comprising: a supply reel winding an ink film therearound; a take-up reel which rolls up the ink film fed out from said supply reel; and a housing accommodating said supply reel and said take-up reel, said housing being arranged so that a space accommodating said take-up reel is larger than a space accommodating said supply reel.
Claim 18
Dependent Claim
70 words
An ink film cassette which is detachably attached to a thermal transfer recording device, comprising: a supply reel winding an ink film therearound; a take-up reel which rolls up the ink film fed out from said supply reel; and a housing accommodating said supply reel and said take-up reel, said housing being arranged so that a space accommodating said take-up reel is larger than a space accommodating said supply reel.
