Abstract
The utility model discloses a flash trigger for a digital camera. The flash trigger for the digital camera comprises an awakening signal and shooting signal converting unit, a microprocessor unit and a radio-frequency emission unit, wherein the microprocessor unit is provided with a plurality of contacts respectively corresponding to awakening signal outputs of various camera hot shoes, and one contact corresponds to shooting signal outputs of the camera hot shoes.
Description
Technical field
The utility model relates to the photography and vedio recording device assembly, relates in particular to a kind ofly to draw the sudden strain of a muscle device for digital camera.
Background technology
Draw and dodge the device that device is the various light fixtures uses of cooperation in studio.Wirelessly draw sudden strain of a muscle and normally use in pairs, reflector is installed on the camera hot shoe, and the hot shoe pin of flashing light in the receiver junction chamber draws effectively that to dodge distance distant, does not have connecting line, and is more flexible.Reflector generally is contained on the camera, and the frequency range receiver links other photoflash lamp light fixtures.
The existing wireless camera that dodges reflector and be necessary for each brand (for example canon, nikon, olympus, pentax etc.) a transmitter of independent design that draws that has a wake-up signal causes managerial confusion easily, causes easily sale simultaneously, and storage is chaotic.In addition, the consumer must buy the corresponding wireless sudden strain of a muscle transmitter that draws that has wake-up signal again if change camera in the process of using, do not have versatility, inconvenience.Therefore, for the reflector that has wake-up signal, how to reduce design, produce, storage, the costs such as sale, the convenience that increases the consumer is the problem of studying in the industry.
Summary of the invention
The purpose of this utility model is to overcome the problem that above-mentioned prior art exists, and proposes a kind ofly to draw the sudden strain of a muscle device for digital camera.
The technical solution adopted in the utility model is, design and a kind ofly draw the sudden strain of a muscle device for digital camera, comprise: wake and take signal conversion unit up, microprocessor unit and rf transmitter unit, wherein, described microprocessor is provided with a plurality of signals and receives the contact, and the shooting signal output of the corresponding camera hot shoe in a contact is used in the respectively wake-up signal of corresponding multiple camera hot shoe output simultaneously.
In a preferred embodiment, described microprocessor unit is provided with 4 signals and receives the contact.Compared with prior art, the utlity model has following beneficial effect:
1. promote user's convenience, reduce purchase cost;
2. reduce design, manufacturing and management cost, increase the flexibility of selling.
Description of drawings
Below in conjunction with drawings and Examples, structural principle of the present utility model is described, wherein:
Fig. 1 is structured flowchart of the present utility model;
Fig. 2 is the fundamental diagram of the utility model one embodiment;
Fig. 3 is the circuit diagram of the utility model one embodiment.
Embodiment
Design of the present utility model is waking up and taking the signal unification and draw in the sudden strain of a muscle system to the wireless of one multiple camera.
As shown in Figure 1, the sudden strain of a muscle device that draws that the utility model proposes comprises: wake and take signal conversion unit up, microprocessor unit and rf transmitter unit.As shown in Figure 2, microprocessor is provided with a plurality of signals and receives the contact, respectively corresponding canon, nikon, olympus, the wake-up signal output of the multiple camera hot shoe such as pentax, use simultaneously the shooting signal output of the corresponding camera hot shoe in a contact, order is taken in emission.During work, microprocessor unit is made identification and processing according to the wake-up signal characteristics of each brand camera hot shoe, and by wireless radio-frequency emission unit wake-up signal is sent.In an embodiment of the present utility model, microprocessor unit receives 4 kinds of camera (canon, nikon, olympus, pentax) wake-up signal of output output, when receiving a wake-up signal, read and judge any type of waking up, and then send the wake command corresponding to this type.
As shown in Figure 3, draw the sudden strain of a muscle device and also comprise a control circuit, this control circuit is connected with microcontroller by the wake-up signal of 4 kinds of cameras parallel with one anotherly, connect a resistance and a triode of each wake-up signal wherein, the emitting stage of triode is connected with hot shoe by a resistance, and four control ends of microprocessor are connected with wireless radio-frequency emission unit respectively again.Also connect on the microprocessor on two electrodes of a crystal oscillator Y1, crystal oscillator Y1 and be respectively equipped with capacitor C 1 and capacitor C 2, produce stable clock signal when being used for microprocessor work.
The utility model can be made identification and processing according to the wake-up signal characteristics of a plurality of brand camera hot shoes, and by wireless radio-frequency emission unit wake-up signal is sent, for consumers in general provide larger facility.Simultaneously, be convenient to the production and selling management.
Should be understood that above-mentioned description for specific embodiment is comparatively detailed, can not therefore think the restriction to the utility model scope of patent protection, scope of patent protection of the present utility model should be as the criterion with claims.
