专利汇可以提供Copying device专利检索,专利查询,专利分析的服务。并且PURPOSE: To easily treat a photosensitive sheet by pressing a recording sheet carrying a 2nd component to be discolored as the result of reaction with a 1st component on its surface against the periphery of a rotary drum passed through a prescribed rotating position and destroying a microcapsule with weak mechanical breaking strength to develop an image on a recording sheet.
CONSTITUTION: A pattern 1a is drawn on the lower surface of an original 1 with ink or the like, ultraviolet rays is irradiated from a discharge tube 3 to the pattern 1a and its reflected light forms an image on a rotary drum 7 through a lens 5. Namely, a microcapsule immediately before exposure is an unhardened microcapsule 11a, and after exposure, a hardened part 11b and an unhardened part 11a are generated in accordance with the pattern 1a of the original 1. At the timing the recording sheet 17 is pressed against the rotary drum 7 side, only the recording sheet 17 part contacted with the unhardened microcapsule 11a is contacted with an inner component stored in the microcapsule 11 because the breaking strength of the unhardened microcapsule 11a is weaker than that of the hardened microcapsule 11b, so that a developer part 18a corresponding to the pattern 1a of the original 1 is developed.
