Abstract
Abstract The present invention relates to an angle sensor for musical tone control which controls a musical tone in response to changing angles at an articulation of the human body. Both ends of a pair of plate members are coupled pivotally and movably around an axis parallel to both faces of plate members. This pair of plate members are attached on the interior side of articulation of the human body by attaching means to generate a signal in response to the bending motion of the articulation. Thus, a musical tone control signal in response to the bending angles is outputted from detecting means which is placed on the plate members to control musical tone.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
116 words
An angle sensor for musical tone control comprising: a pair of plate members coupled pivotally and movably around an axis which is parallel to both faces of said plate members; detecting means for detecting a signal in response to an angle when said pair of plate members pivot in relation to each other around said axis, said detecting means generating a musical tone control signal in response to said signal to control a musical tone; attaching member for arranging said pair of plate members on the interior side of the bending articulation so that said pair of plate members pivot in relation to each other around said axis in response to the bending motion of articulation.
Claim 2
Dependent Claim
116 words
An angle sensor for musical tone control comprising: a pair of plate members coupled pivotally and movably around an axis which is parallel to both faces of said plate members; detecting means for detecting a signal in response to an angle when said pair of plate members pivot in relation to each other around said axis, said detecting means generating a musical tone control signal in response to said signal to control a musical tone; attaching member for arranging said pair of plate members on the interior side of the bending articulation so that said pair of plate members pivot in relation to each other around said axis in response to the bending motion of articulation.
Claim 3
Dependent Claim
61 words
An angle sensor for musical tone control according to claim 1 wherein said detecting means comprises a tubular resistance portion integrally or rigidly formed at one end of said plate members, and a slide contact formed with said axis which is slidably inserted into said tubular resistance portion to change resistance in response to the bending angle of said plate members.
Claim 4
Dependent Claim
70 words
An angle sensor for musical tone control according to claim 1 wherein said detecting means comprises a spring and a pressure sensing element urged by said spring, in which one end of said spring is fixed at one plate member and the other end is urged to said pressure sensing element placed on the other plate member to output signals in response to the bending angle of said plate members.
Claim 5
Dependent Claim
45 words
An angle sensor for musical tone control according to claim 1 wherein said attaching member comprises a band having a retainer, in which said retainer slidably holds said plate member in the longitudinal direction of said plate members in response to the movement of articulation.
