摘要：【課題】給紙圧を変更可能な給紙装置において、厚紙用の大きい給紙圧の設定で給紙が終了した場合に、使用頻度の高い薄紙用の小さい給紙圧に戻るようにし、使用の利便性を向上させ、給紙性能を適正化する。【解決手段】給紙装置は、上下動可能な給紙台3 上の用紙に当接して回転する給紙ロール6を、給紙圧が小さい第1位置と給紙圧が大きい第2位置との間で、給紙圧可変機構11,20 によって任意に切り換えられる。給紙圧が大きい第2位置にある状態で給紙台が下降すると、給紙ロールの下方への移動が給紙圧可変機構に伝達されて第1位置へ切り替えられ、給紙圧が薄紙用の小さい値に切り換えられる。【選択図】図3

摘要： PROBLEM TO BE SOLVED: To suppress dispersion of heating characteristics of heating resistance elements without needing resistance value measurement in driving or complicated current-carrying control, and further without increasing trimming amount.SOLUTION: A current-carrying control based on a difference between resistance value of a plurality of heating resistance elements and an overall average resistance value is not performed on each heating resistance element, and a current-carrying control based on a difference between an average resistance value of the heating resistance elements of each of a plurality of unit blocks of heating resistance elements and a target resistance value is performed on the heating resistance elements of each unit block. Thus, the heating resistance elements can be heated in a condition such that the dispersion range W2 of each heating resistance element is smaller than a conventional dispersion width W1.

摘要： PROBLEM TO BE SOLVED: To provide a thermosensitive stencil base sheet for obtaining an excellent printing image by preventing a decrease in aging surface smoothness of a thermoplastic resin film of the sheet even in the case of leaving the sheet for a long time in the state of winding in a roll state or leaf state and hence preventing a decrease in punchability by a thermal head. SOLUTION: (1) In the thermosensitive stencil base sheet obtained by laminating a thermoplastic resin film and a porous support, a film having 0.0 μm of PPS smoothness and 0.1 to 10 μm of a thickness is bumped against the support side of the sheet, and the measured PPS smoothness is 1.2 μm or less. (2) A film having 0.0 μm of PPS smoothness and 0.1 to 10 μm of a thickness is bumped against the surface of the support laminated with the film, and the measured PPS smoothness is 0.9 μm or less.

摘要： PROBLEM TO BE SOLVED: To provide an emulsion ink for stencil printing which is highly concentrated and less blotting and can give printed matter made proof against offset because of the improved fixation of the colorant remaining on and near the surface of paper and to provide a process for stencil printing therewith. SOLUTION: This ink is a water-in-oil (W/O) emulsion ink containing a water-insoluble colorant in the water phase, wherein a heat-meltable component of a thermosetting component insoluble in the ink is contained. The mean- particle diameter of the heat-meltable component or the thermosetting component is desirably 0.01-10μm. When stencil printing is performed with this ink, and the obtained printed matter is heat-treated, the ink can be rapidly fixed. If a silicone oil is added to the ink, offset to a heat treatment means such as rollers can be reduced without fail.

摘要： PROBLEM TO BE SOLVED: To provide a thermal stencil printing base paper which enables attainment of a clear and high-quality image free from a void or nonuniformity of density even in a high resolution. SOLUTION: In the thermal stencil printing base paper constituted of a thermoplastic resin film and an ink passing porous substrate, a dispersion index of the reflected light of the substrate is 13 or above and the total sum of the area rates of a high basis weight region and a low basis weight region in 0.5 mm 2 or above of the substrate is 3% or below, provided that the dispersion index=h/(L×100) where h is the maximum peak frequency and L the maximum class exceeding 500 frequencies-the minimum class exceeding 500 frequencies+1, as to a 64-class histogram of the image density of the reflected light obtained by taking in (10 cm) 2 by 787 pixels. The high basis weight region is (the class of the maximum peak frequency+5 classes) or above, while the low basis weight region is (the class of the maximum peak frequency-5 classes) or below, and the total sum of the area rates (%)=ä(the total area of the high basis weight region of 0.5 mm 2 or above+the total area of the low basis weight region of 0.5 mm 2 or above)/(the area of the image taken in)}×100.
