Abstract

A cradle position sensing mechanism that includes a scale unit having a scale, which is used to detect the position of the cradle, formed thereon and being extended to cover a sliding range within which the cradle can be slid; and a sensor unit that moves in the directions, in which the scale unit is extended, along with the slide of the cradle so as to detect the scale of the scale unit. The cradle position sensing mechanism serves as a digital linear encoder. Based on the reading on the scale detected by the sensor, the cradle position sensing mechanism calculates the position into which the cradle is slid.
