Abstract:
1. A jig for assembling a rotor including a lower jig locating a rotor casing in its upper part and an upper jig to pressurize the rotating shaft to press-fit the rotating shaft to the rotor casing, comprising: a support plate located at the upper part of the lower jig opposite to the rotor casing to support the rotor casing in a direction opposite a direction in which force pressing the rotating shaft acts; and a guide jig pressurized by the upper jig to support a rotor casing in a direction opposite an acting direction of reaction force which is generated in the rotor casing by the support plate, wherein the support plate is made of the same material as a rubber ring mounted to the rotor casing to prevent the slippage of a recording medium, and has the same thickness as the rubber ring, the support plate supporting a surface of the rotor casing having no rubber ring.
