A multilayer electronic substrate is manufactured by employed: a first conductor layer arranged on an insulating substrate; an insulator arranged on the first conductor layer; a resistor arranged on the insulator; and second conductor layers for sandwiching the resistor to be connected to this resistor. In an arithmetic coding section, from among the syntax elements of input image compression information, the framefield flag is first encoded by a framefield flag context model. Rear left and right strut assemblies respectively include rear left and right knuckles. When a transmissive original is being scanned, the light of the second light source passes through the opening of the calibration element and the transmissive original, and then enters the scanning module. The invention also relates to an image fixing device using the sliding member.
