  • Patent number: 6374068
    Abstract: An aid tool used for aiding in replacement operation of a part to be replaced in an image forming apparatus. This aid tool includes: a part holding unit for holding a part to be replaced; and a mounting portion for removably mounting the part holding unit on an image forming apparatus. The part holding unit is for example a part housing container for housing a part, and may also serve as a packaging container which houses a new replacing part. The part housing container may include, for example, a main body for receiving the part to be replaced, and a lid for openably closing the main body.

  • Patent number: 5604176
    Abstract: A heat-sensitive recording material comprises a recording layer containing a colorless or light-colored basic dye and a developing agent on a support. The recording layer further contains a polyethylene having a melting point not lower than 60.degree. C., which is obtained as an emulsion not comprising a surfactant.The heat-sensitive recording material may be prepared by coating on a support an aqueous coating composition, which contains a colorless or light-colored basic dye and a developing agent together with a polyethylene emulsion comprising a polyethylene having a melting point not lower than 60.degree. C. but no surfactant (e.g. emulsifier), to form a recording layer.

  • Patent number: 4809043
    Abstract: A document illuminating device, for use in an electrostatic copying machine or the like includes an illuminating lamp, a main reflecting device partly surrounding the illuminating lamp, and a subsidiary reflecting device disposed opposite to the illuminating lamp and the main reflecting device. The difference between a first quantity (L.sub.1) of light illuminating a document via a first illuminating light path ranging from one side to the document without reflection by the subsidiary reflecting device and a second quantity (L.sub.2) of light illuminating the document via a second illuminating light path ranging from the other side to the document with reflection by the subsidiary reflecting device is adjusted to not more than 15% of the sum of the first and second quantities (L.sub.1 +L.sub.2).
