Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
161 words
A rotary position control device comprising: (1) a motor having an output shaft with a pinion; (2) a disk member having a toothed portion on its circumferential part, said disk member being rotated by said toothed portion meshed said pinion; (3) a first limit stop provided on said disk member; (4) a second limit stop provided on said disk member; and being angularly positioned with respect to said first limit stop; (5) a rod member disposed in said first and second limit stops for limiting further rotation of said disk member by engaging said first or second limit stop; (6) an electromagnetic solenoid for driving said rod member when energized; and (7) a third limit stop provided on said disk member and being positioned between said first and second limit stops for limiting the rotation of said disk member between the first and second stop positions of said disk member by holding said rod member when said electromagnetic solenoid is energized.
Claim 2
Dependent Claim
161 words
A rotary position control device comprising: (1) a motor having an output shaft with a pinion; (2) a disk member having a toothed portion on its circumferential part, said disk member being rotated by said toothed portion meshed said pinion; (3) a first limit stop provided on said disk member; (4) a second limit stop provided on said disk member; and being angularly positioned with respect to said first limit stop; (5) a rod member disposed in said first and second limit stops for limiting further rotation of said disk member by engaging said first or second limit stop; (6) an electromagnetic solenoid for driving said rod member when energized; and (7) a third limit stop provided on said disk member and being positioned between said first and second limit stops for limiting the rotation of said disk member between the first and second stop positions of said disk member by holding said rod member when said electromagnetic solenoid is energized.
Claim 3
Dependent Claim
27 words
A rotary position control device as claimed as claim 1, wherein said first, second and third limit stops are formed in one body with said disk member.
Claim 4
Dependent Claim
51 words
A rotary position control device as claimed as claim 2, wherein said disk member has a guiding wall provided in association with said first and second limit stops whereby said rod member is guided along the guiding wall by the rotation of said disk member when said electromagnetic solenoid is energized.
Claim 5
Dependent Claim
29 words
A rotary position control device as claimed as claim 3, wherein said rod member comprises a rolling member whereby said rolling member contacts and rolls along the guiding wall.
Claim 6
Dependent Claim
29 words
A rotary position control device as claimed as claim 3, wherein said third limit stop consists of a recessed portion provided in the area halfway in the guiding wall.
Claim 7
Dependent Claim
48 words
A rotary position control device as claimed as claim 5, said device further comprising an elastic member provided at each of said first, second and third limit stop portions whereby further rotation of said disk member is prevented by said elastic members while lessening the impact force thereon.
Claim 8
Dependent Claim
46 words
A rotary position control device as claimed as claim 1, wherein said first, second and third limit stops are arranged and positioned such that they are approximately on circumferential line on side opposite to that of said disk member on which said toothed portion is provided.
