Abstract

In the disclosed camera, a manually operated film advance lever and a shutter button are arranged conveniently to be operated when the camera is held for a horizontal shot, i.e., an exposure during which the film frame is oriented horizontally. A coupling arrangement, in an adapter suitable for mounting on the camera, engages a camera film winder and shutter release and contains a second winding lever and a second shutter release button both oriented in a position suitable for taking a vertical shot.

Claims

1. For an elongated film format camera having a housing and a winding arrangement with a manual winding member and a shutter release arrangement with a shutter release member located on the housing in a first position relative to an operator'"'"'s hand position for convenient use when the camera is held for an elongated, horizontal film format, a vertical format adapter comprising:

an adapter housing attachable to a camera housing,

coupling means on said adapter housing for engaging the winding arrangement and the shutter release arrangement in the camera,

a second manual winding member and a second shutter release member coupled to the coupling means and located on the adapter housing at positions corresponding to the first manual winding member and the first shutter release member relative to the hand of an operator when the adapter is attached to the camera and the adapter and camera are held for vertical film format.

2. An adapter as in claim 1, wherein said adapter housing includes a chamber for holding a spare photographic member.

3. An adapter as in claim 1, further comprising

means for holding a battery,

connecting means for connecting the battery, and

selector means responsive to the attachment of said adapter to the camera to supply electrical power from the battery to the camera.

4. An adapter as in claim 1, further comprising

two female threaded portions for receiving a tripod male screw,

a botton panel on the adapter housing for holding one of said threaded portions, and

a side panel on the adapter housing for holding the other of said threaded portions.

5. An adapter as in claim 1, wherein said coupling means includes a mechanical first coupling arrangement coupled to said second winding member for coupling to the winding arrangement in the camera and a second coupling arrangement connected to said second release member for coupling to the shutter release arrangement in the camera.

6. An adapter as in claim 5, wherein said second coupling means includes electrical transmitting means for transmitting an electrical signal from said second release operating member to said camera.

7. A camera system, comprising:

a housing for holding film and shiftable into a plurality of film format positions including a normal position,

first film winding operating means for operation when the housing is held in the normal film format position,

first shutter release operating means for operation when the housing is held in the normal film format position,

second winding operating means and second release operating means for operation when the housing is held in a second film format position at an angle to the first film format position,

coupling means for coupling said first winding operating means and said second winding operating means,

second coupling means for coupling said first release operating means and said second release operating means with each other,

said first and second coupling means coupling said operating means so that each of said operating means is made effectively independent of the other in performing a winding operation and a releasing operation.

8. A camera system as in claim 7, wherein said first winding operating means and said second winding operating means are disposed on the housing at approximately right angles to each other.

9. A camera system as in claim 7, wherein

in the normal film format position, said first winding operating means and said first release operating means are located parallel to each other on one upper face of the housing, and

said second winding operating means and said second release operating means are provided on one side face of the housing.
