Abstract

PURPOSE:To predict the moment that the shutter is released, so as not to lose the shutter chance, by allowing a camera to have a function by which an operator of the camera can release the shutter at any time by a remote control. CONSTITUTION:Both of a part having a function for emitting an electric signal (radio wave), etc., for releasing a shutter being in the inside of a camera body 4, and an emission switch 1 for an electric signal, etc., for operating this signal emitting function are held in an emitting device for an electric signal, etc., of a separate structure body from the camera body 4. In case of containing a receiving part 3 for an electrical signal, etc., in the camera body 4, it is also allowed that the receiving part 3 is integrated into the camera body 4 so that it does not attract attention. In this way, an operator of the camera can release the shutter at any time by a timing which the operator has selected, by holding the emitting device 2 for an electrical signal, etc., and being in the front, etc., which have been separated from the camera body 4 supported by a tripod, etc.

Description

[Detailed Description of the Invention] The present invention relates to a camera that has the function of being able to release the shutter at any time using a remote control mechanism, in addition to the conventional manual shutter, and the shutter can be released using a remote control. be.

Some conventional cameras have a self-timer mechanism that automatically releases the shutter, but with a self-timer, the number of seconds until the shutter is released is determined by a fixed value, so you miss the chance to take a photo. The disadvantage is that it often happens.

That is, in the self-timer, there is a time delay of about 1° before the shutter is released so that the camera operator can also move in front of the camera to take a picture after the timer starts operating. However, the time before and after the photo shoot is relatively long for the person being photographed to adjust and maintain their facial expressions, and it is not possible to accurately predict the moment when the shutter will be released after the self-timer starts operating. There are many cases where people are not in a unified state of mind and end up appearing in photos with unnatural or unwilling expressions.In order to avoid regrets when taking a photo opportunity, it is important to ensure that the people in the photo take a certain amount of time to capture the moment when the shutter is released. It is necessary to be able to predict accurately.

The present invention was invented to eliminate the above-mentioned drawbacks of the prior art, which often leave behind a chance of fogging, and the camera operator has a function that allows the camera operator to turn off the shutter at any time using a remote fist control. The present invention is a new creation based on the inventor's many years of unfortunate experience using automatic cameras with self-timers.

The structure of the present invention will be explained with reference to the drawings. [A] A part inside the camera body 4) that has a function of emitting an electric signal (radio wave) etc. to turn off the shutter, and this signal emitting function. Electrical signals etc. that operate the emitting switch (
1) and 2) are held in an electric signal emitting device (2) that is a separate structure from the camera body (4).

[Top] An electrical signal receiving part (3) for receiving signals emitted from the electrical signal emitting device (2) is built into the camera body (4). Alternatively, the electrical signal receiving portion (3) may be made into a separate structure from the camera body (4) and electrically and mechanically connected to the camera body (4).

[C] A part having a function of releasing the shutter based on the signal received by the electric signal receiving part (3) built into the camera body (4) is provided in the camera body (4). Alternatively, the electrical signal receiving part (3), which is a separate structure from the camera body (4), has an *fffi for releasing the shutter upon reception of the signal, and connects it to this receiving part (3). 4) Cut the shutter inside the camera body.

The basic structure of the present invention has been described above, and there are the following embodiments to which this is applied. That is, when the receiving part (3) for electrical signals etc. is built into the camera body 4), the receiving part (3) should be built into the camera body 4) so that it is not noticeable on the surface.
It may be incorporated inside. If the electrical signal receiving part (3) is made into a separate structure from the camera body (4), it can be connected to the camera body (4) when necessary, or it can be placed near the camera body <4) to release the shutter when necessary. shall be.
An electrical signal receiving part (3) is built into the top of the tripod (8) that supports the camera body (4), so that when the signal is received, the signal can be sent to the camera body and the shutter can be released. It can also be configured. The tripod (8) can also be used as an antenna for receiving electrical signals. Furthermore, even if the shutter is configured to turn off within a short time such that the people being photographed can predict the moment when the shutter will turn off, for example, 1 to 2 seconds after emitting or receiving an electrical signal, it is not a real problem. The effects of invention are significant.

The cameras covered by the present invention include relatively inexpensive ordinary small cameras and automatic cameras, as well as full-fledged single-lens reflex cameras and
No matter the type.

As an advanced embodiment of the present invention, it is possible to emit light or sound instead of emitting electrical signals (radio waves), etc., so that the camera can be used at a distance from the camera. Even in cases other than these electric signals, the same effects as electric signals can be obtained.

The present invention has the configuration and structure described above, and when using this, as shown in Figure 2, the camera operator (9)
has an electric signal emitting device (2), is located in front of the camera body (4) supported by a tripod (<8), etc., and releases the shutter at any time selected by the operator (9). When taking a photo with a large group of people, including the camera operator (9), everyone should be in front of the camera, and the operator (9) should release the shutter at any time, even in succession, in response to the voice, etc. I can do it.

A consisting of a device that emits electrical signals etc. and a receiving part
The method of remote control using IIW is a technology that has been widely seen in home televisions, stereo equipment, etc., but if this method is applied to the shutter opening/closing mechanism of a camera according to the present invention, it will be possible to achieve a method that has not been seen in the past. No, great new effects arise. For example, when a parent and child take a picture together at a tourist resort with one small child, the parent holds the electric signal emitting bag R1i (2) and stands in front of the camera side by side. Then, by pressing the electric signal emission switch (1) while watching the child's expression, you can decide on a chance. When taking a commemorative photo with a large group of people, including the camera operator (9), the operator (9) holding the electric signal emitting device (2) releases the shutter for everyone in the photo by giving a signal such as a voice. By giving advance notice of the timing, you can release the shutter at a time that satisfies everyone. While everyone including the camera operator (9) remains in front of the camera, the shutter can be released any number of times in succession. Furthermore, when taking observation photographs of animals, the camera operator can hide in a place hidden away from the camera body and can turn the shutter at any time.

By further developing the remote control function itself, it is also possible to use conventional technology to freely move the direction of the camera body, which is fixed on a tripod, etc., and to point the lens in the direction of the subject, including the operator. be. Even in such cases, it is possible to equip the camera body with a function that allows the operator to turn off the shutter at any time using remote control; [flu is also included within the scope of the rights of the present invention.
