Abstract
Abstract A rotational force transmission device is disclosed, in which even if a driving wheel is continuously rotated, the driven wheel is capable of intermittent motion. The device provides hardened rollers instead of springs so that said rollers are forcibly isolated from the driving wheel when the rotating force is not being transmitted.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
192 words
A latch operated clutch comprising, a continuously rotating cylindrical main rotary member, a follower rotary member loosely fitted in said main rotary member, said follower rotary member being provided with at least one cut-away portion in the peripheral surface thereof, a roller disposed in said cut-away portion, a disc having mounted thereon a first supporting means for said roller, a second supporting means mounted on the front surface of said follower rotary member, said disc being provided with an opening at a position correspondIng to said second supporting means, a third supporting means mounted on the front surface of said disc, biasing means extended between said second and third supporting means for biasing said follower rotary member and said disc in respectively opposite rotational directions so that said follower rotary member and said roller are in engagement, releasing means for releasing the engagement between said follower rotary member and said roller when in a non-transmission mode, stopping means for stopping the rotation of said disc, and control means for controlling said stopping means for converting a continuous rotation of said main rotary member into an intermittent rotation of said follower rotary member.
Claim 2
Dependent Claim
192 words
A latch operated clutch comprising, a continuously rotating cylindrical main rotary member, a follower rotary member loosely fitted in said main rotary member, said follower rotary member being provided with at least one cut-away portion in the peripheral surface thereof, a roller disposed in said cut-away portion, a disc having mounted thereon a first supporting means for said roller, a second supporting means mounted on the front surface of said follower rotary member, said disc being provided with an opening at a position correspondIng to said second supporting means, a third supporting means mounted on the front surface of said disc, biasing means extended between said second and third supporting means for biasing said follower rotary member and said disc in respectively opposite rotational directions so that said follower rotary member and said roller are in engagement, releasing means for releasing the engagement between said follower rotary member and said roller when in a non-transmission mode, stopping means for stopping the rotation of said disc, and control means for controlling said stopping means for converting a continuous rotation of said main rotary member into an intermittent rotation of said follower rotary member.
Claim 3
Dependent Claim
50 words
A clutch according to claim 1, wherein said releasing means comprises a cam plate integrally provided with said follower rotary member and having at least one flat portion, a lever member having one end thereof adapted to press against said flat portion, and spring means for biasing said lever member.
Claim 4
Dependent Claim
22 words
A clutch according to claim 2, wherein a plurality of said flat portions are provided corresponding to the number of desired intermittence.
Claim 5
Dependent Claim
38 words
A clutch according to claim 1, wherein said stopping means comprises a notched portion provided in said disc and a lever engageable with said notched portion, and said controlling means comprises an electromagnetic solenoid for controlling said lever.
Claim 6
Dependent Claim
22 words
A clutch according to claim 4, wherein a plurality of said notched portions are provided corresponding to the number of desired intermittence.
Claim 7
Dependent Claim
14 words
