摘要： Dot patterns formed by two different half-tone processes of the plurality of tone processes for each color of CMYK and formed with/without the presence and absence of transparent toner overlap are created and test patches obtained by collecting the dot patterns are printed. The printed test patches are read to generate image data, and tone correction arithmetic is performed on the basis of the image data. Concentration in the case of the presence of transparent toner in a different half-tone process is predicted based on the dot patterns with the transparent toner overlap in the test patches and concentration in the case of the absence of transparent toner in a different half-tone process is predicted based on the dot patterns without the transparent toner overlap in the test patches. The tone correction arithmetic is performed based on the predicted values.

摘要： In a chain transmission a standard ISO roller chain meshes with a modified sprocket having a root diameter larger than the root diameter of a standard sprocket designed for use with the standard chain. The angular tooth pitches can be either of two kinds. In a first version, the sprocket has two irregularly distributed tooth pitches, θ−Δθ and θ+2Δθ, there being two tooth pitches θ−Δθ for each tooth pitch θ+2Δθ. In a second version, the sprocket has three angular tooth pitches, θ−Δθ, θ, and θ+Δθ, in equal numbers, also distributed irregularly.

摘要： Pressing plates press side faces of a roll paper loaded into a roll paper holder unit of the drop-in type, thereby preventing overrun of the roll paper caused by an inertia force from occurring. Each of the pressing plates is urged by two coil springs which are placed respectively on inner and outer circumference sides of the roll paper. The coil spring on the outer circumference side has a higher elasticity than the coil spring on the inner circumference side. According to the configuration, the pressing force of the pressing plates due to the elasticity of the coil springs is gradually reduced in accordance with reduction of a diameter of the roll paper.
