Filed: 1987-03-17
Abstract: PURPOSE:To attract a recording medium to a padding member with adequate attraction force by providing the through hole for passing air stream to a downstream side in the traveling direction of the recording medium and the means adjusting the flow rate of the air-stream. CONSTITUTION:The air inside a recessed part 14 flows out to the external part through the through hole 16 by being dragged by a recording medium 15 in the case of traveling of the recording medium 15. Namely negative pressure is generated inside the recessed part 14 due to the air inside the recessed part 4 being rapidly diffused (expansion) to attract the recording medium as shown by double dotted chain line. At this time a flap 18 is open and located at the position as shown by double dotted chain line, for instance, but due to a pressure detecting element actuating circuit 23 being in working state as well the pressure inside the recessed part 14 is detected by a pressure detection element 19. And in the case of being lower than specific pressure a piezoelectric element 26 is driven by a pressure/voltage converting circuit 24 and driving circuit 25 to close the flap 18 by specified extent and the value. The recording medium is thus attracted to the pad with adequate adsorption force at all times while under traveling.

Abstract: PROBLEM TO BE SOLVED: To improve the picture quality by leaving a photosensitive resin only in the lower part of spacer particles by exposure and development and backing the resin to fix the spacer particles on the wiring part or black matrix part of a substrate. SOLUTION: A positive photosensitive resin 3a, for example, containing spherical spacer particles 4 having a uniform particle size is applied on a transparent substrate 1 having a wiring part 2 or a resin matrix part 2. Then the whole surface of the substrate is irradiated with and exposed to UV rays without using a pattern mask, and then developed with an organic alkali solution to remove all of the resin containing spacer particles on the pixel openings except for the specified part 2. Then after the substrate is irradiated with UV rays through the remaining resin layer side to expose the resin, the resin is also developed so as to firmly hold the spacer particles 4 with the resin 3a on the specified part 2. Then the remaining photosensitive resin 3a is completely cured by baking and the spacer particles 4 is stably fixed with the resin 3a on a predetermined part 2.
