发明名称 CAMERA PROVIDED WITH PSEUDO ZOOM PHOTOGRAPHING FUNCTION
摘要 PURPOSE:To save power by changing the focal distances of both a finder and a photographing lens in the case film is loaded in response to the intention of changing the focal distance and changing only the finder in the case the film is not loaded. CONSTITUTION:The existence of the film is checked in response to the on/off of a cartridge detecting switch S6. When the film does not exist, a camera is restored to a stop state, and when the film exists, the focal distance of the photographing lens is calculated based on the position of the finder and electronic zoom magnification, and a lens zoom driving mechanism 33 is driven. Namely, the existence of the film is checked, and only the zoom driving mechanism 23 of the finder part 21 is driven to execute the zoom-in and the zoom-out of the finder in the case of judging that the film does not exist, and the lens zoom driving mechanism 33 of a photographing lens part 31 is driven only when the film exists. When both a zoom-out switch and a zoom-in switch are turned off, only display data is outputted.
