<P>PROBLEM TO BE SOLVED: To provide a damper device configured to regulate movement of an object as desired, and restrain waiting time taken until shifting to feeding operation of the object from getting longer. <P>SOLUTION: The damper device includes a base 110 having a first sliding surface SP in a paper moving direction, and a slider 120 having a second sliding surface TP opposed to the first sliding surface SP via a viscous grease, and sliding along the first sliding surface between a first position where a stopper is located at a regulation position and a second position where the stopper is located at a release position. The first sliding surface has at least either a surface shape formed in such a state that the area opposed to the second sliding surface is smaller in a second section R2 where the slider slides to the second position from a third position compared with a first section R1 where the slider slides from the first position to the third position where movement of paper stops, or a surface shape formed in such a state that the gap with the second sliding surface is larger in the second section R2 than in the first section R1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
