摘要： A quick mirror return mechanism includes a return spring and a quick return setting member, which are formed, in the region where they abut against each other, so that as the return spring is stressed, the resilient force of the return spring is directed closer to the direction in which a setting pawl moves. A main mirror for a finder, a stationary member, a mirror-up lever, a main mirror drive, a sub-mirror and a sub-mirror driver form together a six-bar linkage wherein the main mirror moves upward while swinging back and the sub-mirror moves into overlapping relationship with the main mirror when the latter has completed its upward movement. The quick return mechanism which is biased with an increased force is disposed on a front panel of a camera, thus preventing any excessive force from being applied to a mirror box. A light receiving element unit is disposed in the bottom of the mirror box. A light receiving element unit is disposed in the bottom of the mirror box, and is arranged on a substrate, tilting of which can be separately adjusted in the fore-and-aft and lateral or left-and-right direction by adjusting the angular positions of a first and a second lever.
