ABSTRACT:
A photographic camera in which a film cartridge, housing a photographing film having a recording belt capable of recording sound signal, can be loaded, wherein for the purpose of effecting the recording of sound signal simultaneously with photographing a sound signal recording head and a constant speed film running mechanism are provided at the sound signal recording part being separated from an intermittent film transport mechanism for running the above mentioned film with a constant speed. The above mentioned sound signal recording head can take an active state wherein sound signal recording on the above mentioned sound signal recording belt is possible and an inactive state wherein said recording is impossible, selectively, and the shifting from said inactive state to the active state is done in an association with the action of the locking means of the cover of a chamber for the above mentioned film cartridge so that simultaneous sound recording and photographing can be done immediately after the camera cover is locked.
