摘要： In an exposure precision tester for a camera, including a flexible wiring board where a photometric sensor is implemented is contained in a case. The case has an appearance similar to that of a film cartridge loaded by drop-in operation and is insertable into a film cartridge cell of the camera. Exposure test can be performed without a back lid because the photometric sensor measures and outputs the exposure energy in the state that the photometric sensor is positioned at a film mask portion by rotating an operation part of a feed shaft with the case being inserted in the camera.
