Abstract:
A photometric device for measuring subject brightness in a lens-fitted photo film unit with a flash device that includes a circuit board having printed circuits on a print side and circuit elements on a mounting side that is opposite to the print side, the circuit board being mounted in the film unit with its print side oriented toward an object side of a taking lens of the film unit, the photometric device comprising:a light measuring circuit printed on the print side of the circuit board; a photo sensor having a photoreceptive surface on its front face, and a pair of terminals extending rearward from the photo sensor, the photo sensor being put on the print side of the circuit board such that the terminals are put through the circuit board from the print side to the mounting side, and then bent toward the circuit board to be put through the circuit board from the mounting side to the print side, and tips of the terminals that protrude from the print side are soldered on the light measuring circuit; and a photometric window formed through a front cover of the film unit, for exposing the photoreceptive surface of the photo sensor.
