Title:
DRIVE TRANSMISSION DEVICE, SHEET FEEDER DEVICE, AND IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP2015075137
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To restrict noise generated at the time of motion of a moving member by a less-expensive and simple configuration in a drive transmission device that there is provided a cam member of which rotation is stopped by motion of a moving member.SOLUTION: A cam-shaped part 13b is provided with an elastic deformed part 13f having a recovering surface 13d2 of which radius is larger than a stopper part 13c, the recovering surface 13d2 can be abutted against an engaging part 15b1 of a flapper part 15b positioned at a releasing position. The elastic deformed part 13f is resiliently deformed in a direction where a radius of the recovering surface 13d2 becomes small due to abutment of an engaging part 15b1 of the flapper part 15b positioned at a releasing position against the recovering surface 13d2. When motion of the flapper part 15b from its releasing position toward its engaged position is started under a state in which the engaging part 15b1 is abutted against the recovering surface 13d2, the engaging part 15b1 continues to slide from the recovering surface 13d2 on the abutment part 13d of the cam-shaped part 13b as the cam rotates, and then it is guided up to the stopper part 13c.
