Abstract: PURPOSE:To prevent accumulation of static electricity in heating rollers for conveying a photosensitive material while heating said material by providing conductive ring which fitts freely onto a conductive shaft and has a grounding terminal to the heating rollers. CONSTITUTION:A pair of the 1st heating rollers 50, a pair of the similar 2nd heating rollers and a pair of the 3rd heating rollers are disposed in a heat development and transfer section. The thin conductive planar rings 156 are disposed between ball bearings 150 and dash walls 155 in the deep parts of notches 151 of side walls 71 into which the ball bearings 150 of respective driving shafts 51 are fitted. Each ring 156 has a hole 157 into which the driving shaft 51 fitts loosely. the circumferential edge part of the hole 157 contacts only the outside shell 152 of the ball bearing 150 and, therefore, the ring 156 is held in place between the outside shell 152 and the wall 155. The ring 156 has a bent or curved surface so as to generate elastic force when the ring is held in place between the shell 152 and the wall 155; in addition, the ring has the grounding terminal 158. The terminal 158 is grounded by mounting a freely attachable/detachable connector 159 thereto. The accumulation of the static electricity in the heating rollers is thereby prevented.

Abstract: PURPOSE:To make cell thickness constant and response speed uniform and to prevent generation of Newton's rings by using plastic substrates formed integrally with polarizing films in constituting a liquid crystal display body of a reflection type. CONSTITUTION:Spacers 5 such as glass fibers are disposed in a liquid crystal layer 6, and upper and lower electrode substrates 1, 2 sandwich polarizing plates 11, 21 therebetween. Plastic films 12, 22, 13, 23 are formed into one body with the films 11, 21. The film 13 (on the layer 6 side) of the substrae 1 sandwiching the film 11 has the coefft. of expansion smaller than the coefft. of expansion of the film 12 on the other side and therefore the substrate 1 subjected to straining at a high temp. is going to curve into a recessed shape toward the outside at an ordinary temp. or in the service temp. range. The film 23 of the substrate 2 on the layer 6 side has the coefft. of expansion smaller than that of the body 25 and therefore the substrate is going to curve into a recessed shape toward the outside opposite from the substrate 1. There are, however, the spacers 5 in the layer 6 and since the spacers 5 are hard, the substrates 1, 2 are not compressed to the thickness of the spacers 5 or below and the uniform thickness of the cell is maintained over the entire part.
