Abstract
The utility model relates to a synchronous closedown light-flash switch for a camera shutter. Based on an electronic shutter camera, the utility model is additionally provided with a flash control triode, a resistor and a flash controlled silicon, so that a conventional electronic shutter camera can also shoot photos with strong real effect of moving trace at the back of a moving body. The utility model has the advantages of reasonable design, simple structure, etc., and is suitable to be installed on focal plane type electronic shutter cameras as well as on between-lens type electronic shutter cameras.
Description
The utility model relates to a kind of camera, the switch of control flashlamp flash of light in particularly a kind of camera.
The shutter of electronic shutter camera is opened and closed by electronic circuit control, when camera is pressed shutter when taking pictures, the shutter of camera is opened relay by shutter and is opened, when shutter is opened fully, be installed in that contact seat board on the curtain axle rotates and with the hot-shoe flash contact switch connection, hot shoe seat on camera case makes the flashlamp flash of light again, when finish timing up, close triode control shutter close relay with shutter close by the electronic shutter in the circuit again, at this moment, the contact seat board revolution that is installed on the curtain axle disconnects flash trigger switch, because the time compole of the each flash of light of flashlamp is short, so the peak value of each flash of light all finishes in a flash in the shutter opening process, be called shutter and open the synchronization flash camera, captured photo is present common photo.But, if in the environment of night or dark, take when having the moving object of luminous point, automobile, motorcycle etc. as motion, usually adopt the shooting of glistening of slower shutter speed, therefore, the car light isoluminescence point all can be taken into the track of motion in long timing up, and other parts can only be clear could taking in a flash of flashlamp flash of light, captured photo then is that the movement locus of luminous point has been gone to the front of moving object, is not inconsistent with actual conditions.Stay the photo of moving object back for the movement locus that can photograph luminous point, have only the high-grade camera that has shutter close synchronization flash function of import just can take at present, cooperate Nikon SB-26, SB-27 type flashlamp as Nikon F4, F5, F90X type camera; The EOS650 of Canon, EOS620 join the high gear camera of models such as 300EZ, 420EZ type flashlamp and just are furnished with shutter close synchronization flash function, open the synchronization flash camera and the camera of models such as common camera such as sea-gull DF-300, phoenix DC-828, the KR-10 of Ricoh is shutter, can't photograph the photo of shutter close synchronization flash effect.In order to photograph the photo of shutter close synchronization flash effect, curtain synchronization flash switch after in No. 99228692.1 patents, having designed reed-type, but because mechanical structure, installation accuracy requires high, and can only be before having on the camera of focal plane electronic shutter of curtain and back curtain repacking use, and to do not have preceding curtain and after between the mirror of branch of curtain the camera of formula electronic shutter just can not be suitable for.
The purpose of this utility model is in order to overcome the weak point of curtain synchronization flash switch behind the above-mentioned mechanical type, design a kind of structure simpler, install and use more easily the electronic type camera shutter and close the synchronization flash switch.
The utility model is to have increased a flash of light control triode, a resistance and a flash of light control controllable silicon on the basis of electronic shutter camera, the input end of flash of light control triode be connected with the output terminal that camera shutter is closed triode again after resistance is connected, the output terminal of flash of light control triode is connected with the flash of light control silicon controlled control utmost point, and flash of light control silicon controlled anode and negative electrode are serially connected between the hot shoe seat mid point and flash trigger switch of camera.
Accompanying drawing 1 is the circuit connection diagram of the shutter close synchronization flash switch of one of the utility model embodiment;
Accompanying drawing 2 is circuit connection diagrams of two the shutter close synchronization flash switch of the utility model embodiment.
Referring to attached Fig. 1 and 2, the flash of light control triode Q in the accompanying drawing
