Title: Production of liquid crystal display device
Inventor: NONAKA MASANOBU
IPC: G02F1/1343
Filed: 1989-07-31
Abstract: PURPOSE:To prevent the orientation defect of liquid crystal molecules by static electricity and the generation of display defects by previously providing common peripheral electrodes around two arrays of band-shaped electrode groups apart the spacing of <=1/2 the shortest spacing between the individual band-shaped electrode groups. CONSTITUTION:The common peripheral electrodes 13 of two arrays of the band-shaped electrode groups 11, 12 on a substrate are previously provided in proximity apart the spacing H of <=1/2 the shortest spacing between the individual band-shaped electrodes constituting the band-shaped electrode groups 11, 12. In addition, the common peripheral electrodes 13 are concealed by adhesive seals. The spacing with the common peripheral electrodes 13 is smaller than the spacing between the adjacent band-shaped electrodes and, therefore, a discharge is generated in the spacing with the common peripheral electrodes 13 when a potential difference is generated between the adjacent band-shaped electrodes by the electrification of static electricity. The generation of the discharge in the display part and the orientation defect of the liquid crystal occurring therein are prevented in this way.

Abstract: PROBLEM TO BE SOLVED: To prevent a sheet from being removed from a discharge tray before stapling by alarming that a stale means is operated when an object is detected within a prescribed range near the discharge tray by an object detecting means at a prescribed timing before the operation of the staple means. SOLUTION: When a sheet after copying is discharged to a discharge tray 22, a signal for driving a staple device 25 situated in a position not interfering with the discharge of the sheet in discharge to a stapling position is outputted from a master CPU. When it is detected that a part of a human body is present near the discharge tray 22 by human body sensor 37 (37a-37c) just after the output or after the lapse of a prescribed time, a voice composer is instructed so as to output a message by voice, and the message is outputted through a speaker 4. Thus, stapling is surely performed, and an alarm can be emitted only when an operator erroneously removes the sheet.
