    摘要： A table start position selecting mechanism for an electrophotographic copying machine of the type with a movable table comprises a unistructural lamp unit with a lamp and a primary mirror for initially reflecting light from a document on the table. A table start position detection switch is attached to a supporting plate which is independent of the lamp unit and adjustable with respect thereto in the direction of motion of the table. A positioning device such as a pin is affixed to the lamp unit at the center of its optical axis such that the switch-supporting plate can be easily and accurately positioned with respect to the lamp unit in the direction of motion of the table.

    摘要： An image reading apparatus is provided with a transparent plate horizontally disposed on which an image reading operation is performed, and a transporting device disposed above the transparent plate for transporting an original sheet to the transparent plate. The transporting device includes a pressure roller for pressing the original sheet onto an upper surface of the transparent plate at a pressure applying position and transporting the original sheet along the upper surface of the transparent plate. The image reading apparatus is also provided with a light source disposed below the transparent plate for illuminating through the transparent plate a portion of the transported original sheet. The illuminated portion of the original sheet is positioned on the upper surface of the transparent plate at an upstream side of the pressure applying position with respect to a transporting direction of the original sheet. The image reading apparatus is further provided with a detecting device for detecting through the transparent plate a reflection light from the illuminated portion of the original sheet.

    摘要： A lens repositioning device for use in a copying machine which device comprises a generally elongated lens carriage having a lens assembly fixedly mounted thereon; a single traction cable adapted to be driven by a drive unit and including generally intermediate first and second cable portions over the length thereof which extend parallel to each other and are, when the traction cable is driven by the drive unit, moved at the same velocity and in the same direction, and a guide member. The lens carriage is rigidly connected at its opposite ends with the respective first and second portions of the traction cable. The guide member is operable during the movement of the traction cable accompanied by the movement of the lens carriage to guide the lens assembly to follow a curved path of a predetermined configuration.
