摘要： PURPOSE:To prevent a photosensitive recording medium from being wasted and to reduce a running cost by housing the unexposed photosensitive recording medium supplied to an exposure table in a housing part before an error signal is generated in the case that the jam of a mask original plate supplied to the exposure table is detected. CONSTITUTION:In the case that the mask original plate 15 is jammed on the way that it is carried to an alignment device 31 and theexposure table 52 in the process that an image is formed, it is detected by jam detection sensors 130a and 130b which are respectively provided in a mask original plate carrying path 21 or in a mask original housing part 102 that the mask original is jammed. Then, it is judged by a CPU whether the photosensitive recording medium 50 is already exposed or not at the time that the original plate 15 is jammed. In the case that it is judged that the medium 50 is not exposed, the unexposed medium 50 is housed again in a cartridge 51 by rotating a DC motor and a driving roller 57.

摘要： PURPOSE:To obtain the copy of a light transmissive color original by providing a control means for forming the copy of the original by performing transmissive exposure in a state where the color original is in contact with a photosensitive recording medium. CONSTITUTION:A color developer sheet 60 is fed from a cassette 61 by a suction cup 62 in synchronism with the movement of a photosensitive recording medium 50. The pressure roller 71 of a pressure developing device 70 is allowed to press-contact with the sheet 60 while rotating in a direction shown by an arrow and the medium 50 is fixed on an exposing board 52. The medium 50 is pressed and fed in a state where it is superposed on the sheet 60, and an unhardened microcapusle on the medium 50 is ruptured with pressure, then a color image corresponding to a latent image on the medium 50 is developed on the sheet 60. In a thermal fixing device 80, the sheet 60 is heated by air which is heated by a heater 81 and circulates in a casing 83 by an impeller 82 so as to accelerate the color developing of the color image. Binder polymer(binding resin) for fixing a color developing medium on the base paper of the sheet 60 is thermally melted, then the surface of the sheet 60 becomes smooth and properly golssy.
