摘要： A mirror arrangement for reflex cameras is provided. A main mirror is pivotably connected to a steering lever, which is rotatable about a rotary spindle, such that the main mirror is pivoted and lowered during transition into the lower position. A secondary mirror is rotatably mounted to a housing via a pivot arm that is arranged pivotably about a rotary spindle that is fixed to the housing. The rotary spindle of the pivot arm is parallel to the rotary spindle of the steering lever. The mirror arrangement further comprises an actuating lever, which is connected to the main mirror and the pivot arm of the secondary mirror. The actuating lever is configured to provide simultaneous movement of the main mirror and of the secondary mirror from the upper position into the lower position and vice versa.

摘要： A shutter for a photographic camera, having a first and a second pretensioned shutter curtain which are respectively retained in the tensioned state by a first and a second pivotably mounted retaining latch (7, 11) in interaction with a first and second curtain latch (3, 4), the first retaining latch (7) being coupled to a camera release for enabling release of the first curtain, and the second retaining latch (11) being coupled to a release device, which is controlled as a function of the release of the first curtain, for enabling release of the second curtain, wherein the first and second retaining latches (7, 11) are respectively assigned first and second movement-releasing active surfaces (9, 10; 13, 14) which are each coupled either to a mechanically controlled or an electronically controlled curtain-release enabling arrangement.

摘要： A mirror arrangement for reflex cameras, consisting of a main mirror (2), which can pivot in a housing (4), and a pivotable secondary mirror (6), wherein the main mirror (2) is partially transmissive in a central region (5) and the secondary mirror (6) is arranged downstream of this partially transmissive region (5) in the direction of the light and is matched to this region (5) in terms of its size, and wherein, in an upper position, both mirrors (2, 6) are situated in one plane and, in a lower position, the main mirror (2) is aligned at 45° with respect to the upper position and the secondary mirror (6) is aligned such that it is tilted with respect to the main mirror (2), is characterized in that the main mirror (2) is connected in an articulated manner to a steering lever (19), which is rotatable about a rotary spindle (20), such that the main mirror (2) is pivoted and lowered during transition into the lower position, the secondary mirror (6) is connected to a pivot arm (22), which is arranged pivotably about a rotary spindle (23) which is parallel to the rotary spindle (20) of the steering lever (19) and in that an actuating lever (15), which is connected to the main mirror (2) and the pivot arm (22) of the secondary mirror (6), is present for the simultaneous movement of the main mirror (2) and of the secondary mirror (6) from the upper into the lower position and vice versa.
