PURPOSE:To prevent photographing in an unsuitable state, by storing and displaying various information on a liquid crystal display plate provided in the vicinity of the outside of a finder, so that the confirmation of an object to be photographed can be controlled in itself. CONSTITUTION:A finder eyepiece part 2 is made capable of controlling the passing of a light beam by an applied state of voltage, and various information is displayed in the lump on a display part 3 of a liquid crystal display plate 1. The luminance of an object to be photographed passes through a photoelectric converting element 10, a comparing circut 11 and a switch 12 interlocked with an electric power supply switch 16 for a stroboscope, and is provided to an oscillating circuit 13. Also, one end of an Ne tube 18 of a stroboscopic device is connected to the circuit 13 in accordance with a changeover of the switch 12. When energy for light emission of the Ne tube 18 is insufficient, an output of the circuit 13 operates a transistor 14 intermittently, flickers the eyepiece part 2, and displays an unsuitable state of photographing. Also, the operation of the display part 3 is controlled by combining a storage circuig group 23, in which a numerical value related to an operation of a switching circuit 22 is stored in advance, and the circuit 22. |
