装置。[Claims for Utility Model Registration] 1. A first plate on which a first pattern is formed and provided on a fixed lens barrel, a first brush provided on a focus ring for reading the first pattern, and and a first converting means that converts the information of the first pattern read by the brush into an electrical signal and outputs it, and an absolute converter that generates an absolute distance signal in conjunction with the rotation of the focus ring. a second plate provided on the fixed lens barrel on which a second pattern is formed; a second brush provided on the zoom ring for reading the second pattern; and a second conversion means for converting the information of the second pattern into an electrical signal and outputting it, and a movement signal generation means for generating an image plane movement amount signal in conjunction with rotation of the zoom ring. A signal generator for use in a zoom lens barrel, characterized in that the first plate and the second plate are adjacently provided on the same peripheral surface of a fixed lens barrel. Generator. 2. The signal used in a zoom lens barrel according to claim 1, wherein the first plate and the second plate are adjacent to each other in the optical axis direction and are formed as a single flexible printed board. Generator.
