摘要: Automatic self-aligning ball metals rotatably mounted at both end parts of a rotor shaft in an electric motor are supported by holding devices. The holding device is designed in the form of a disc having a flange portion around the outer periphery thereof. It is formed with a plurality of pawls having different intensities of resilient force which extend in the radial direction from an area located in the proximity of the flange portion. The pawls having a higher intensity of resilient force and the pawls having a lower intensity of resilient force are alternately arranged in the peripheral direction of the holding device and the inner part of each of the pawls is bent at a certain inclination angle. The pawls having a lower intensity of resilient force are adapted to come in contact with the metal ball earlier than the pawls having a higher intensity of resilient force. Each of the pawls having a higher intensity of resilient force has a width wider than the pawls having a lower intensity of resilient force. The pawls having a higher intensity of resilient force may have a thickness more than the pawls having a lower intensity of resilient force on the assumption that they have the same width. Usually, two kinds of pawls which are alternately arranged are used. Three kinds of pawls may be employed.

摘要: One of several corona dischargers used in an electrophotographic apparatus is connected to a power source transformer so as to selectively operate these corona dischargers. The power source transformer is provided with a tertiary winding, to which a switching device is connected. When the switching device is turned on, a secondary output from the transformer becomes lower than a corona discharging limit voltage, whereby the corona discharging stops.
