Title:
直線性を測定するための方法と装置
Document Type and Number:
Japanese Patent JP3646065
Kind Code:
B2
Abstract:
A method and an apparatus for measuring linearity in a reproduction appliance includes an operating carriage bearing a scanning or recording device. The operating carriage is able to be moved in discrete steps in a given direction along a straight line. The operating carriage is successively moved along partial segments of the line. Each of the partial segments is longer than a travel corresponding to one of the steps and is shorter than the entire length of the line. The partial segments each have an exactly defined length defined by an additional carriage moveable along the given direction. The number of steps needed for each partial segment are counted and deviations between values for a travel of the operating carriage resulting from the partial segment and values for the travel of the operating carriage resulting from counting the steps are calculated.
