    摘要： A reat resistant bush is arranged between a heating roller and a bearing for supporting said heating roller, said heat resistant bush (31) and a gear (27) or sprocket fixedly mounted on said heating roller for revolving said heating roller being formed integrally from resin materials having a lower coefficient of thermal conductivity, an excellent heat resistance and the mechanical strength required for gears.
    Remarkably smaller noises are generated, a heating roller being able to be effectively heated, and an assembling operation also being easily achieved.

    摘要： An electrostatic copying process and apparatus capable of forming copies in at least two different ratios. The formation of a copied image involves exposure scanning of the image of an original document and projecting it on a photosensitive member (10) through an optical device (66). The change of the ratio of copying is achieved by changing the ratio of projection of the image of the document onto the photosensitive member by the optical device, and also changing the speed of scanning.

    摘要： The electrostatic copying apparatus according to the invention is adapted for copying at variable ratios and has an optical device for performing slit exposure scanning of an original document and for pro­jecting its image onto a photosensitive member. The distribution of the illuminance of a document illumi­nating lamp (70) in the widthwise direction is pre­scribed such that when a lens (78) is held at the equal scale position, the decaying characteristics of the lens in the widthwise direction are offset to render the illuminance distribution in the widthwise direction on the photosensitive member (10) sub­stantially uniform, and when the lens is held at the predetermined ratio position, an exposure adjusting plate (150) is positioned partly in a light path leading from the document to the photosensitive member (10), said exposure adjusting plate (150) being adapted for compensating variations in illuminance on the photosensitive member (10) which are ascribable to the displacement of the optical axis in the width­wise direction caused by the movement of the lens (78) from the equal scale position to the pre­determined ratio position and to variations in the degree of focusing on the photosensitive member (10) caused by the change of the projecting ratio and also to variations in the speed of slit exposure scanning.

    摘要： An engagement mechanism for a developing means (43) in an electrostatic copying machine, wherein an original image is guided to a photoreceptor (400) arranged on a rotary drum (41) via a focusing device (26), forming an electrostatic latent image on the photoreceptor (400) and the electrostatic latent image being positively changed into a toner image by the developing means (43), and the rotary drum (41) is supported in a freely rotatable fashion by the supporting member at the supporting frame body (5) which can be drawn out from a vertical front plate (18) of the copying machine body (1) and a contact surface (507, 508) controlling a horizontal position of the developing means (43) and a guide (505, 506) controlling a vertical position are provided at a fixed position of the supporting member, and furthermore the engagement member (509) rotatable to one direction from the standard position is provided movably toward the rotary drum (41) at the standard position with a constant impetus thereto separately from the supporting member and the developing means (43) is arranged movably toward the rotary drum (41) by engaging an engagement part formed at a fixed position of the engagement member (509) aforementioned with an engagement part formed at the fixed position of the developing means (43).

    摘要： A cleaning device for an electrostatic photographic copying machine comprising a sensitive drum (1) provided with a paper-stripping groove (2) at one side thereof, a pointed end of an upper blade (7) for stripping residual toner being in contact with said sensitive drum (1), a pointed end of a lower blade (9) for guiding toner being in contact with said sensitive drum at the upper reaches from said upper blade (7) in the rotary direction of said sensitive drum, said upper blade (7) stripping residual toner from the surface of said sensitive drum, and the stripped toner being guided toward a toner-withdrawing portion (11) by means of said lower blade (9), characterized by a groove-cover (13) covering said paper-stripping groove (2) at least from said upper blade (7) to said lower blade (9) so that the groove-cover (13) may be in contact with said lower blade (9).
    Residual toner, which was stripped from the surface of the sensitive drum, does not enter the paper-stripping groove Thereby, troubles in other parts of the apparatus and hindrances to the finish of copying can be securely prevented.
