  • Patent number: 5920741
    Abstract: A film guide device for guiding a front end portion of a film to a position before a film cartridge so as to be positioned at a film attachment position includes a film bending portion for allowing the front end portion of the film to be positioned at the film attachment position in a state in which the front end portion is bent in a widthwise direction of the film. The front end portion of the film being bent or curved in a widthwise direction of the film enables it to be made stiff. As a result, the front end of the film can be precisely positioned at the film attachment position and thus failure of hooking a film with the attaching tool can be prevented.

  • Patent number: 5318622
    Abstract: Novel non-baked color pencil leads are here disclosed which can be obtained by forming a blend composition from a filler, a pigment, a binder and the like without using any wax, at least one of the pigment and the filler being all or partially covered with a fluorinated aromatic compound, kneading the blend composition with a solvent and/or a plasticizer, extruding the kneaded material, drying the extruded articles to remove the solvent and/or the plasticizer therefrom, and then impregnating the porous articles with an oil, a fat and/or a wax.The thus obtained non-baked color pencil leads are remarkably excellent in mechanical properties such as bending strength and pointed end strength, has a smooth writing performance, and permits the drawing of uniform lines. A high-temperature and short-time drying treatment is possible, which can remarkably decrease a manufacturing cost.
