Claims

[Scope of Claim for Utility Model Registration] (1) In a photometric device for a photoprinting machine that is equipped with a light source section, an optical section, an exposure section, and a photometry section, a single light source for exposure is provided, and the optical path of the film transmission by this light source is A scanner photometry device for a color photographic printing machine is configured to introduce a part of the image into a photometry sensor via a scanner filter for photometry. (2) In the photometry device of a photoprinter, which is equipped with a light source section, an optical section, an exposure section, and a photometry section, a scanner filter is attached to a rotary plate frame that is pivoted for rotational drive, and the scanner filter is mounted relative to this rotary plate frame. A scanner photometry device for a color photographic printing machine is equipped with a single photometry sensor on the optical axis of a color photo printer. (3) A scanner photometer for a color photographic printing machine according to claim 2, wherein said scanner filter is mounted on a rotary plate frame which is pivotally supported to be rotationally driven by a motor. (4) The scanner photometer for a color photographic printing machine according to claim 2, wherein the scanner filter is mounted on a rotary plate frame which is pivotally supported so as to be rotationally driven by a pulse motor.
