Title: Image recorder
Inventor: KAGAYAMA SHIGERU
IPC: G03B27/32
Filed: 1990-03-05
Abstract: PURPOSE:To improve the sensitivity of a microcapsule paper by executing exposure under an environment that the concentration of oxygen is rarer than the atmosphere at least at the exposure time of the microcapsule paper between a time before it is exposed and at the time when it is exposed. CONSTITUTION:A driving device 22 works as soon as a vacuum pump 23 is started and a shutter 21 is closed. Then, a vacuum room 20 is evacuated. Next, light emitted from an exposure lamp 36 is casted on an original placed on an original platen 12 and the microcapsule paper 33 is exposed by the light reflected on the original. Then, a latent image is formed on the paper 33. Therefore, since the oxygen does not exist near a microcapsule on the paper 33, radical generated from photosetting initiator by the exposure is not oxidized by the oxygen. Thus, the sensitivity of the microcapsule paper 33 is enhaced and time required for the exposure is shortened.
