Title: Paper feeder of image forming device
Inventor: MIYAZAWA TAKUJI
IPC: G03G15/00
Filed: 1994-12-16
Abstract: PURPOSE: To prevent an increase in a load of a paper feeding part even at paper feeding time of a paper sheet to which a toner image is fixed by multiple/ double-sided copying by arranging a means to generate a length signal to show a sending-out directional length of the paper sheet and a means to control driving time of a paper feeding roller according to the length signal. CONSTITUTION: When a second time copy is started, a paper sheet 40 is inserted between a paper feeding roller 19C and a separating member 28 by a pickup roller 19B brought into pressure contact by a swinging support 35, and a single sheet is carried out to a paper sheet guide 41. At this time, the paper feeding roller 19C is driven in time according to a sending-out directional length of the paper sheet 40 stored in a memory. When the paper feeding roller 19C stops driving, the paper sheet causing friction with the separating member 28 is restricted to a length equal to an interval between the paper feeding roller 19C and the pickup roller 19B, and a problem by friction is solved.  The paper feeding roller 19C becomes free in the sending-out direction of the paper sheet 40 by a one-way clutch 30 arranged between it and a driving shaft 29, and a pulling-out time load of the paper sheet 40 by a regist roller is reduced.

Filed: 1990-11-19
Abstract: PURPOSE:To improve the operability by providing a tilt mechanism which tilts up an input device to a device equipped with a display output device which rotates between a storage position and a display position. CONSTITUTION:When the display output device 8 is unlocked and from the storage position, the input device 9 turns tilting as shown by an arrow B1, a base guide 15 turns as shown by an arrow C1, and the lower end part 15a moves on the bottom surface of a device main body 14 as shown by an arrow A2. Then when the device 8 is turned completely to the display position, the lower end part 15a of the guide 15 engages the lock piece 20 of the main body 14 and the motion in the direction of A2 is corrected. The device 9 is therefore tilted up as the device 8 rotates, and then locked at a tilt position where it tilts at an angle theta2 to the horizontal state. Consequently, the devices 9 and 8 come closer to each other to improve the operability, and the operability of a switch is also improved.

Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To decrease influences of diffracted light in a proximity exposure process and to obtain a pattern with fidelity to the pattern of a photomask by forming a negative black resist on a substrate, exposing the resist via a photomask to light of specified light quantity, and developing the exposed resist to form a pattern.

The applied layer is hardened temporarily, for example, by using a hot plate or the like, and then exposed by using an exposure device having wavelengths appropriate to the sensitivity of the black resist 7 and by using a mask 3 having a specified pattern. When the resist is developed, the part shielded from light by the mask 3 in the exposure process is dissolved with a developer to expose the surface of the substrate 1, while the exposed part remains as the black matrix 2 pattern. By controlling the quantity of exposure light to 14.0 to 70.0 mJ/cm2, only the part directly exposed to light is fully hardened, while the part shielded from light including the exposed part to diffracted light can be removed by developing.
