<p>PURPOSE:To prevent a black frame from being formed around an image by exposing a non-image part again by using a light shielding mask which covers only a part corresponding to the image display part of a liquid crystal shutter on a microcapsule sheet. CONSTITUTION:A fixed reflection mirror 22 reflects light reflected by a movable reflection mirror 21 provided between a halogen lamp 7 and the liquid crystal shutter 17 to the microcapsule sheet 3. The light shielding mask 23 disposed in an optical path between the mirror 22 and the sheet 3 has the same size as the image display part of the liquid crystal shutter 17, and it is constituted of a light shielding part arranged at a position corresponding to the image display part and a light transmitting part arranged at the position corresponding to the non-image part of the liquid crystal shutter 17. Then, the image displayed on the image display part of the liquid crystal shutter 17 is exposed on the sheet 3 by the halogen lamp 7 and further exposed on the sheet 3 again by using the light shielding mask 23.</p> |
