Abstract
Abstract In a clutch mechanism formed by adhering a friction member to a face of one of a pair of rotating elements with an adhesive member and arranged to bring the surface of the other of the pair of rotating elements into pressed contact with the friction member by an urging member, a recessed part is formed in the face of the one of the rotating elements to which the friction member is adhered, so as to accumulate and retain pressure sensitive adhesive seeping from the adhesive member.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
84 words
A clutch mechanism comprising: a) first and second rotating elements supported to be rotatable coaxially; b) a transmission member fixed to a face of said first rotating element with an adhesive member; c) urging means for pushing said second rotating element against said transmission member; and d) a recessed part formed in the face of said first rotating element to which said transmission member is fixed, said recessed part being arranged to accumulate and retain a pressure sensitive adhesive seeping from said adhesive member.
Claim 2
Dependent Claim
84 words
A clutch mechanism comprising: a) first and second rotating elements supported to be rotatable coaxially; b) a transmission member fixed to a face of said first rotating element with an adhesive member; c) urging means for pushing said second rotating element against said transmission member; and d) a recessed part formed in the face of said first rotating element to which said transmission member is fixed, said recessed part being arranged to accumulate and retain a pressure sensitive adhesive seeping from said adhesive member.
Claim 3
Dependent Claim
12 words
A mechanism according to claim 1, wherein said transmission member is disc-shaped.
Claim 4
Dependent Claim
26 words

A mechanism according to claim 3, wherein said plurality of grooves include two groove parts arranged respectively to overlap an inner peripheral edge part and an outer peripheral edge part of said transmission member.
Claim 6
Dependent Claim
68 words
A mechanism according to claim 4, wherein said groove part located at the inner peripheral edge part of said transmission member is formed to have a sectional shape which gradually becomes deeper toward the center of rotation, and said groove part located at the outer peripheral edge part of said transmission member is formed to have a sectional shape which becomes deeper away from the center of rotation.
Claim 7
Dependent Claim
16 words
A mechanism according to claim 1 or 2, wherein said transmission member is made of felt.
Claim 8
Independent Claim
132 words
An apparatus for recording and/or reproducing information on or from a tape, comprising: a) a first rotating element arranged to be rotated by a drive source; b) a second rotating element disposed coaxially with said first rotating element and arranged to engage a reel around which the tape is wound; c) a transmission member fixed to a face of one rotating element of said first and second rotating elements with an adhesive member; d) urging means for pushing the other rotating element of said first and second rotating elements against said transmission member; and e) a recessed part formed in the face of said one rotating element to which said transmission member is fixed, said recessed part being arranged to accumulate and retain a pressure sensitive adhesive seeping from said adhesive member.
Claim 9
Independent Claim
132 words
An apparatus for recording and/or reproducing information on or from a tape, comprising: a) a first rotating element arranged to be rotated by a drive source; b) a second rotating element disposed coaxially with said first rotating element and arranged to engage a reel around which the tape is wound; c) a transmission member fixed to a face of one rotating element of said first and second rotating elements with an adhesive member; d) urging means for pushing the other rotating element of said first and second rotating elements against said transmission member; and e) a recessed part formed in the face of said one rotating element to which said transmission member is fixed, said recessed part being arranged to accumulate and retain a pressure sensitive adhesive seeping from said adhesive member.
