PURPOSE:To expose a photosensitive body to image information with fidelity by clamping a negative plate and a photosensitive material between an exposure plate and a blanket, and squeezing the blanket with a roller during exposure and thus holding the negative plate and photosensitive material in contact. CONSTITUTION:The exposure plate 2 is provided on a case 1 which incorporates a light source. The blanket 3 is provided in a free opening/closing state at distance S from the exposure plate 2, and the negative plate M and photosensitive material M are stacked between the exposure plate 2 and blanket 3, which is pressed. A frame body 5 which is opened and closed together with the blanket 3 is provided with a right and a left pair of a run guide rail 61 and a lateral rocking preventive rail 62 are provided. A squeeze roller 4 has both ends of the shaft supported on the run guide rails 61 through a push pressure adjusting mechanism 6 and a run roller 81 and is movable at right angles to the figure. One place of an endless running belt 100 is fixed to the projection 9 of the pressure adjusting mechanism 7 and the squeeze roller 4 is moved forth and back by a motor which is not shown in a figure. Consequently, the negative plate M and photosensitive material F are brought into contact with each other during exposure to expose the photosensitive material to image information faithfully. |
