A mirror-reflex camera is provided having a viewfinder mirror which can be displaced between a viewing position and a taking position, and an electromagnetic drive for adjusting the viewfinder mirror. The viewfinder mirror can be displaced linearly between the viewing position and the taking position to ensure the quick and reliable adjustment of the viewfinder mirror between the viewing position and taking position, with a relatively low outlay and little expenditure of energy. The electromagnetic drive has a permanent magnet arrangement and a linearly displaceable plunger coil arrangement. The viewfinder mirror is displaceable, in particular, via a driver with the plunger coil arrangement.

Mirror-reflex camera

A mirror-reflex camera, having a mirror support which supports a viewfinder mirror and can be adjusted between two end positions, a viewing position and a taking position. Latches are provided with the mirror support for latching in the end positions. Adjustable engaging levers are provided which engage in the latches in an engaging position and release the latches in a release position. A holding device (such as a plate) is provided for holding a driver. The driver can be adjusted along a driver track by a drive and can be moved in the holding device along its driver track within a distance which is limited by two bearing positions in the holding device. The mirror support can be adjusted above the holding device by the driver in these bearing positions. The engaging means, which can, in particular, be pivotable latching levers, can be adjusted from the engaging position into the release position by the driver.
