Abstract

PURPOSE:To view easily the operation state of a stroboscope in a finder without generating any electric noise by guiding light from the light emitting body in the strobe to the finder through a light guide provided in the strobe and camera. CONSTITUTION:When the power switch of the stroboscope 12 is turned on and the charging amount of the internal capacitor attains to a specific value, a charging pilot lamp 16 turns on. Its light is supplied to the photodetection part 22 of the light guide 20 and consequently, a light emission part 23 emits light. The light enters the photodetection part 26 of a camera-side light guide 26 and the changing completion of the strobe 12 is know over a look at the finder 25. Further, when a light emission bulb 15 emits light after the shutter button of the single-lens reflex camera 11 is released, part of the light enters the photodetection part 21 of the light guide 20, and consequently the light emission part 28 emits light simultaneously with the turn-on operation of the charging completion pilot lamp 16. Thus, the operation state of the stroboscope is viewed in the finder easily without generating any electric noise.

In order to solve this problem, we have already installed an electrical contact on the hot shoe that connects the camera and the strobe, and information on the strobe's operating status is transmitted to the camera body via this electrical contact and displayed using a lamp or LED in the viewfinder. Devices designed to do this are known. However, as cameras become more electronic and are controlled using minute currents, systems that transmit strobe operating status information using electrical signals become the cause of camera "L operation".In other words, electrical noise from the strobe The camera may malfunction.

It is possible to distinguish between completion of charging and completion of light emission by inserting an appropriate filter into the light guide 20 and making the light emission color different, but since both can be distinguished from the timing of light emission, it is not always necessary to differentiate by color. There isn't. Further, a filter may be inserted in the light guide 20 on the side of the light receiving section 21 facing the light emission W 15 to reduce the amount of light.

In addition to the above-mentioned examples, the light emitting bodies in the strobe 12 are known to include automatic dimming confirmation lamps in auto dimming strobes, but the light from these light emitters can also be guided to the viewfinder to check the operating status of the strobe. You can know. On the other hand, in the simplest case, light indicating only the completion of charging or the completion of light emission may be guided to the viewfinder so that the minimum strobe operating status can be known.

"Effects of the Invention" As described below, according to the present invention, the light guide provided in the strobe and the light kite provided in the camera,
It is possible to guide the light from the emitter inside the strobe to the viewfinder. Since no electrical signal is involved in transmitting information on the strobe operating status, there is no room for electrical noise to occur, and there is no risk of electrical noise causing malfunctions in the camera's electronic circuit. In addition, since the light guide only needs to transmit information on whether or not the light is turned on through a short optical path,
Precision is not required, a light guide made of an inexpensive resin product such as acrylic resin can be used, and the structure is simple, so a highly reliable device can be obtained.
