Filed: 1981-06-23
Abstract: PURPOSE:To enlarge the current feeding region of a fan, by forming air-flow deflecting vanes in an air-flow deflecting vane plate in the manner that the width of the vanes at one side of said plate is greater than that of the vanes at the other side, so that the air-flow deflecting vane plate is turned continuously by a substantially regulated air flow produced by a fan. CONSTITUTION:A motor securing section 7 is formed by a plurality of support ribs 8 having a relatively large width and extended radially in a wind tunnel 2. Air flow produced by an axial-flow fan 12 driven by a motor 9 reaches air-flow deflecting vanes 21 after it is regulated or straightened substantially completely when passing through the support ribs 8. The air-flow deflecting vanes 21 constitute a part of an air-flow deflecting vane plate 6 which is supported in a  freely rotatable manner on a pivotal shaft 14 erected from the motor securing  section 7. Here, since arrangement is such that the width of the vanes 21 at one  side of a strengthening rod 20 is greater than that of the vanes at the other side, moment of rotation is produced when air flow is acted to the plate 6, so that it is turned in a clockwise direction.

Abstract: PURPOSE:To assure the tight contact between paper and photosensitive body even during humidification and to decrease transfer defects by providing a member for preventing entrance of paper having an approximately semicircular sectional shape on the surface in the upper part of a corona discharger facing the photosensitive body. CONSTITUTION:A ditac corotron 1 is partitioned by a shield 2 and is disposed adjacently to a transfer corotron 4. Prescribed transfer and destaticization operations are executed by the corotrons 1, 4. The shape of plural pieces of ditac guards 20 provided in the upper part of the corotron 1 is made into the semicircular shape projecting to a photosensitive body 9 side. The front end of the paper 8 carried into the discharger via a paper guide chute 7 contacts first with the photosensitive body 9. The paper 8 past the discharge region of the corotron 4 is electrically neutralyzed by the corotron 1 and is thereby stripped from the body 9. The stripped paper is held supported by the guards 20 and is conveyed in this state to a roller belt 10. The tight contact between the paper 8 and the body 9 is thus assured even during humidification and the transfer defects are decreased.

Abstract: PURPOSE:To obtain to enhance the efficiency and life of a dehumidification agent by preventing the backflow of air when a blower is stopped, by respectively arranging open air shielding members to the suction port and emitting port of a dehumidifier. CONSTITUTION:An open air shielding member 5a is suspended inside the suction port 1a of a humidifier 1 having a dehumidification agent provided therein and an open air shielding member 5b is arranged to an emitting port 1b in a freely revolvable manner. When a blower 2 is rotated, the sucked open air is filtered by the net 4 provided to the suction port 1a and forcibly opens the open air shielding member 5a to be sucked into the dehumidifier 1. Subsequently, the filtered air passes through the dehumidification agent while the dried air forcibly opens the open air shielding member 5b to be exhausted from the emitting port 1b. When the blower 2 is stopped, the open air shielding member 5a is contacted with an inclined part 1c while the open air shielding member 5b is contacted with an inclined part 1d to respectively close the suction port 1a and the emitting port 1b. By this method, the humidity absorbing action of the dehumidification agent 3 is stopped at an unnecessary time.
