Wireless multiflashlight apparatus for a photographic camera

In a wireless multiflashlight apparatus comprising:

• a main flashlight device including a first flash capacitor on which a predetermined voltage is precharged, and a first flash tube coupled substantially across said first flash capacitor to emit a first flashlight ray for illuminating a subject being photographed through the discharge of the voltage precharged on said first flash capacitor upon the shutter operation of the camera;
• and
• at least one additional flashlight device located in the neighborhood of the subject and away from said main flashlight device, said at least one additional flashlight device including a photoelectric conversion element operative to receive flashlight rays emitted from said first flash tube, an amplifier section coupled to said photoelectric conversion element, a switching element coupled to said amplifier section to be made operative by an output signal from said amplifier section, and a flashlight source which includes a second flash capacitor on which a predetermined voltage is precharged, and a second flash tube coupled to said switching element and to said second flash capacitor to emit a flashlight ray for illuminating the subject simultaneously with that from said first flash tube through the discharge of the voltage precharged on said second flash capacitor when a flashlight ray delivered from said first flash tube is received by said photoelectric conversion element and said switching element is made operative by an output signal from said photoelectric conversion element obtained through said amplifier section;
• the improvement wherein:
• said main flashlight device further comprises an additional flashlight generating means coupled to said first flash tube for generating at least a second flashlight ray from said first flash tube, with a predetermined time interval between said first and second flashlight rays, upon the shutter operation of the camera;
• and
• said additional flashlight device further comprises a decoder circuit coupled via said photoelectric conversion element between said amplifier section and said switching element for producing an output signal only responsive to at least two flashlight rays delivered from said main flashlight device being received by said photoelectric conversion element with said predetermined time interval therebetween, said output signal being coupled to said switching element for causing said switching element to become operative to cause a flashlight ray to be emitted from said second flash tube.
