Embodiment of the Invention

4 and 6, the wireless shutter release and the wireless flash synchronizer may receive signals from the transmitter 100, the transmitter connection code 120, and the transmitter 100 equipped with the wireless shutter release button 110. Receiving unit main body 130 and the receiving unit connection cord 140 is composed of four components, such as the transmitter connection code 120 and the receiver connection cord 140 is easily removable connector and cord jack, etc. It is a multifunctional type that can be used as a wireless shutter release or a wireless flash synchronizer by replacing it.

In addition, by replacing only the connection cord (141, 142 ... 149) according to the mechanical, electronic or maker, model of the connection cord 140 of the receiving unit can be equipped with a wide range of universal type that can be applied to any camera or electronic flash Will be.

The main body 100 of the transmitter / receiver adopts a small built-in antenna 100-5 for easy carrying and installation, and adopts a radio propagation method to extend the transmission / reception distance, minimize the transmission / reception direction and the area where transmission / reception is impossible, and malfunction due to interference. In order to prevent a problem, a fixed address is given to a frequency, and a dip switch 100-3 which can adjust an address externally in case of interference is installed, and this dip switch 100-3 is used when multiple releases or synchronizers are used. Different addresses can be assigned to prevent interference.

Looking at the configuration and operation of the first feature, universal wireless shutter release,

The transmitter release button 110 of the transmitter main body 100 is composed of 1-stage and 2-stage switches. When the 1st stage is input, the auto focus signal of the camera is output. When the 2nd stage is input, the camera shutter release signal is output. It can also be applied to autofocus cameras.

It is always on type using small chipset parts with low battery current consumption, and the power is always on, so it maintains the operating standby state that can be operated at any time.

When using the camera shutter release, the user presses the shutter release button 110 of the transmitter main body 100 that is carried by the user in one step, and an autofocus control signal is applied to the button switch 110-4 to be amplified by the electronic plate 110-2. After a series of signal processing, such as a conversion address is transmitted to the outside through the internal antenna (110-5), the power is constantly turned on and received by the internal antenna (130-4) of the receiver main body 130 in the recording standby state The signal is automatically focused on the camera by outputting the autofocus control signal to the electronic release socket 140-1 through the connection code 140 through a series of signal processing such as address verification conversion amplification on the electronic board 130-2. When the adjustment circuit is activated to finish shooting, and then the shutter release button 110 is pressed in two steps, the shutter release signal is applied to the button switch 110-4 so that the amplification conversion advise is performed on the electronic plate 110-2. The signal received by the internal antenna 130-4 of the receiving unit 130, which is first transmitted to the outside through a built-in antenna 110-5 through a series of signal processing procedures such as a grant, is received by the electromagnetic plate 130-. 2) The shutter release signal is output to the electronic release socket 140-1 through the connection code 140 through a series of signal processing processes such as address checking, amplification, and the like. This is taken.

At this time, the connection cord 14O is used to connect a connection cord suitable for a camera maker or a model to the receiver main body 130 and the electronic release socket 140-1.

In addition, a camera using a mechanical release socket instead of an electronic release socket connects the shutter release signal output from the receiver main body 130 to the mechanical release adapter 149 to convert the electrical output signal into a solenoid coil or an eccentric cam of a motor. The device is converted into a mechanical signal using the device of the mechanical release socket 140-2 is delivered to open the shutter.

In addition, if the shutter release button 110 of the transmitter main body 100 is pressed for continuous shooting of the camera and long exposure exposure of 1 second or more, the output signal of the receiver main body 130 receives the same stable and continuous signal as the input signal. The output box has a structure capable of operating at continuous shooting, B (BULB) shutter speed shooting, and T (TIME) shutter speed.

Next, referring to the configuration and operation of the wireless flash synchronizer, which is the second function, the transmitter unit 100 is installed at the camera synchro contact 120-1 of the camera 150, and the transmitter unit 100 and the camera synchro contact 120-1 are installed. Connected to the transmitter connection code 120 and the receiver body 130 is configured to connect to the electronic flash synchro socket 181 of the electronic flash 180 as an electronic flash sync jack 141.

The flash sync signal is generated by the camera at the moment when the shutter is completely opened (first curtain tuning method) or immediately before the shutter is closed (back curtain tuning method), and is transmitted to the camera synchro contact 120-1.

The transmitter main body 100 receives the flash sync signal through the transmitter connection code 12O and performs a series of signal processing such as an amplification conversion address assignment in the electromagnetic plate 110-2, through an internal antenna 110-5. The signal received by the internal antenna 130-4 of the receiving unit main body 130 in which the power is in the standby state is transmitted to the electronic flash through a series of signal processing processes such as address verification conversion amplification in the electromagnetic plate 130-2. The signal is output to the electronic flash synchro socket 181 of the electronic flash 180 through the synchro jack 141 (use according to the model for each manufacturer), and the electronic flash 180 emits light to be exposed to the camera film. The picture is taken with the shutter closing.

At this time, the release button 110 installed in the transmitter main body 100 is used as a button for signal processing confirmation.

As described above, the present invention is a general-purpose multi-function wireless remote controller, which has a function of wireless shutter release (including auto focus control signal) and wireless flash sync, and is widely applied to cameras and flash makers and models by replacing the connection code of the transceiver. It is characterized by the widest possible compatibility.

Also, it can accept auto focus signal and release signal, and it is easy to carry and install by installing the transmitting and receiving antenna inside, and it is always power-on type by eliminating the power switch of the device by using small chipset parts with low battery current consumption. The standby mode is minimized for the user's malfunction and the convenience and operability are enhanced.

From this, the present invention integrates the wireless flash synchronizer function and the wireless shutter release function, which enables high-speed signal processing of the camera, so that no time lag occurs during the signal of the camera release, thereby improving the reliability of the release and providing a stable and continuous signal identical to the input signal. Unlike the long exposure and manual shutter release of the I (INSTANT) shutter as well as the B (BULB) shutter, the camera prevents vibration of the camera due to the release stroke and enables continuous shooting.

As described above, the present invention is a multifunctional general-purpose type that can cope with a function change or a change according to a manufacturer or a model at any time, and is applied to various cameras and electronic flash makers or models to reduce production cost due to mass production and to duplicate purchases of consumers. There is a useful effect to reduce inconvenience and economic loss.
