Abstract: PURPOSE:To enable the flatness of a yoke edge and both core edges to be finished with high precision and at low cost by forming the yoke edge and the core edge on the same plane, and allowing the rotary support of an armature having a plunger to contact the external peripheral wall of the yoke. CONSTITUTION:An armature 13 is energized by a leaf spring for armature 15 so that the edge of a rotary support 13b may contact the edge of a yoke 5, while the other edge may contact a printing wire pin 3.

Abstract: PURPOSE:To easily enable water-proofing even when an operation key are arranged nearby the liquid crystal display device by switching one of switches to a close circuit by a switch changeover part with the signal of the operation key and applying a specific voltage to the electric resistance value of a selected voltage input line. CONSTITUTION:The respective switches 6 - 9 are connected to the switch changeover part 19 connected to the operation key 20 which inputs signals corresponding to the switches. The switch changeover part 19 switches one of the switches to the closed circuit corresponding to the signal inputted from the operation key 20, so a voltage determined with the selected voltage input line among lines 2 - 5 is applied to the visual field angle adjusting voltage input side of the liquid crystal display device 1. The visual field angle is therefore adjustable, the changeover of the switch is controlled by the switch changeover part 19 without any operator's intervention, and the operation key 20 for commanding the operation can be operated by simple pressing operation. Consequently, even when the surface is covered with a soft sheet, the operation key is operated and even when the operation key is arranged nearby the liquid crystal display device, the water-proofing countermeasure can easily be taken with the sheet.

Title: Copying machine
Inventor: IWAMOTO MINORU
IPC: G03G21/14
Filed: 1987-08-13
Abstract: PURPOSE:To prevent remaining toner from sticking on a white ejected sheet by making only the developing bias of a developing system active and those of other electrostatic charge, exposing systems inactive at the time of a mode when a white sheet is ejected from a standby tray without copying anything. CONSTITUTION:Among the developing biases of the electrostatic charge, exposing, developing systems 24, only the one of the developing system 24 is made active at the time of the mode when a white paper is ejected from the standby tray 74 without copying any images, whereas the developing biases of the other systems are made inactive in the same mode. In a mode when an odd-numbered document is automatically fed by means of an auto document feeder to obtain both surface copies, images are copied on the front of a sheet because a final document is odd-numbered, while its back is inverted as it is and is ejected because there is no document. Thus remaining toner on a photosensitive drum never sticks to a white ejected sheet at a time when said sheet is brought close to the photosensitive drum and is ejected.
