Abstract: A manuscript conveyer guide which has a curved surface and a flat surface in a facing portion to an upper surface of the contact glass plate, the curved surface being positioned on the upstream in the manuscript conveying direction, the flat surface being positioned on the downstream in the manuscript conveying direction, and the distance d2 between the flat surface and the contact glass being greater than the distance d1 between the curved surface and the contact glass. The manuscript conveyor guide is arranged over the contact glass plate and guides the manuscript that has passed over the contact glass plate in a direction of discharge.

Abstract: A manuscript conveyer guide wherein its upper surface includes a narrow partial guide surface extending from an end of the guide surface on the side of the contact glass in a direction to separate away from the contact glass, which is in a direction in which the manuscript is discharged, and non-guide surfaces continuous to the partial guide surface, and the partial guide surface forms an inclined surface which is low at an end of the inclined surface on the side of the contact glass and becomes high as it goes away from the contact glass, and the inclined surface is relatively higher than the non-guide surfaces, permitting the manuscript discharged from the contact glass plate to come into contact with the partial guide surface and, further, permitting the manuscript to be guided upward along the partial guide surface.

Abstract: [Problem] To provide a fixing device for a tubular member such as a catheter which is easy to operate, has parts which are easy to tighten, which makes it easy to recognize whether the parts are securely fixed, which is small in size, and which causes minimum irritation of the skin.

Abstract: A manuscript conveyer guide wherein the upper surface thereof includes a narrow partial guide surface extending from an end thereof on the side of the contact glass in a direction to separate away from the contact glass, which is in a direction in which the manuscript is discharged, and non-guide surfaces continuous to said partial guide surface, and said partial guide surface is forming an inclined surface which is low at an end thereof on the side of the contact glass and becomes high as it goes away from the contact glass, and said inclined surface is relatively higher than the non-guide surfaces, permitting the manuscript discharged from the contact glass plate to come into contact with said partial guide surface and, further, permitting the manuscript to be guided upward along said partial guide surface. The manuscript conveyer guide is arranged neighboring the contact glass plate on the manuscript discharge side and effectively suppresses the occurrence of unevenness in the reading of the manuscript.

Abstract: An image forming apparatus for forming an image on a recording material comprising: a plurality of processing devices for forming the image; a detecter for detecting at least a quantity of state relating to a control of the processing devices; an inference computer for inferring, in accordance with the quantity of state, a quantity of control for use to control the processing devices.

Abstract: A conveying guide for conveying a sheet onto which an image has been transferred is made of a synthetic resin having a resistance higher than the resistance of the transfer sheet. The upstream side end of the upper surface of the conveying guide is located sufficiently lower than the position at which the sheet is separated from the surface of the photoreceptor drum. With these arrangements, the charging of the conveying guide due to the friction between the sheet and the guide is prevented, thereby restraining the image quality deterioration.

Abstract: A paper dust removal device detachably mountable to a frame of an image forming apparatus through an opening formed on the frame to remove paper dusts from an outer surface of a roller in the image forming apparatus, the opening of the frame being opposing to the outer surface of the roller, the paper dust removal device includes: a base member; a paper dust holding member fixedly attached to the base member adapted to press contact with the outer surface of the roller; and engaging member engageable with the frame when the paper dust removal device is rotated in an engaging direction due to a friction force generated on the outer surface of the roller by a contact of the paper dust holding member with the outer surface of the roller.

Abstract: A sheet processing apparatus operating in xerographic printing apparatus employs a single-component magnetic toner. The inventive features of the sheet processing apparatus are directed toward smooth transportation and discharge of printing sheets sent through the printing apparatus, across a sheet transport guide, and through an image fixing and sheet transporting unit which finally discharges the printing sheets. Conductivity of the transport guide is selected by the material of which it is made, specified herein to have superficial resistivity in the range of ten thousand to one hundred million megohms.
