Device for controlling image signal recording operation

A device for controlling a recording operation in which an image signal is obtained by an imaging device, said device comprising:

• a scanner optical system forming an image on said imaging device;
• a photographing optical system by which a light beam from an object is condensed so that the object image is formed on a focusing position;
• an electro-developing recording medium detachably mounted between said photographing optical system and said scanner optical system, so that the object image is recorded in said electro-developing recording medium;
• means for sensing whether or not said electro-developing recording medium is mounted;
• and
• means for controlling a position of at least one of said photographing optical system and said scanner optical system, in an optical axis thereof, in such a manner that said focusing position and a conjugate position of said imaging device with respect to said scanner optical system are always coincident with each other, based on an output signal of said sensing means.

A device for controlling an image signal recording operation, said device comprising:

• a photographing optical system which forms an image on a photo imaging plane;
• a scanning optical system that scans an image provided on a scanning plane, and forms an image on a sensor imaging plane;
• a recording medium detachably mounted at a location containing said photo imaging plane and said scanning plane, an image being optically recorded in said recording medium;
• and
• a control system that controls a position of at least one of said photo imaging plane and said scanning plane by moving at least one of the photographing optical system and the scanner optical system along an optical axis in association with whether or not said recording medium is mounted at said location so that said photo imaging plane and said scanning plane are coincident with each other whether or not said recording medium is mounted at said location.
