Abstract:
An intermittent transmission mechanism, comprising:a driving rotor supported to be rotatable about an axis of an input shaft;a driven rotor supported to be rotatable about an axis of an output shaft parallel to the axis of the input shaft, the driven rotor including a member defining arcuate recesses and including an engageable element, wherein the driving rotor includes an engaging element for engaging the engageable element of the driven rotor to rotate the driven rotor intermittently by a predetermined angle; anda cam with a rotation regulating surface movable relative to and along arcuate surfaces of the recesses when the driven rotor is stopped,wherein the engaging element of the driving rotor is displaced relative to the rotation regulating surface axially of the input shaft,wherein the engageable element of the driven rotor is displaced relative to the member defining the recesses axially of the output shaft,wherein the engageable element of the driven rotor is a gear defining teeth arranged at predetermined intervals throughout a circumference thereof,wherein the engaging element of the driving rotor is a partial gear having teeth for meshing with the gear, andwherein the input shaft of the driving rotor has an angular velocity change mechanism connected thereto for minimizing an angular velocity of the driven rotor when the engaging element of the driving rotor begins to engage the engageable element of the driven rotor and when the engaging element ends the engagement.
