PHOTOMETRY DEVICE FOR CAMERA

摘要

PURPOSE:To obtain exposure information with good accuracy at the moment when a camera is exposed, by providing a vibration absorbing member between a photodetector of amorphous construction and a fitting base of the photodetector. CONSTITUTION:A photodetector 1 of amorphous construction is fitted to a pinted board for shutters. A hole 2a is made on the printed board 2 for photodetection. A fitting position of the photodetector 1 on the printed board 2 is provided with a silicone rubber 4a as a vibration absorbing member for vibration absorption and bonding purpose and the photodetecting plane of the photodetector is fitted downward on it. An electrode 1a of the photodetector 1 and a pattern 2b of the printed board 2 are bonded with a wiring 3. With this construction, since the vibration and shock due to the operation of shutter mechanism of a camera is absorbed with a vibration absorbing member 4a and the output of the photodetector of amorphous construction is not fluctuated, stable exposure accuracy can be avoided.
