Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a camera with a built-in strobe, and particularly to an optical system protection mechanism and a strobe operating mechanism.

[Conventional technology]

Conventionally, some hand-held cameras have an optical system protection plate attached to the front of the camera body so that it can be moved laterally but cannot be removed, and an opening/closing mechanism is created by moving it laterally to open/close and protect the lens.

Furthermore, in many conventional cameras with a built-in strobe flash, the flash photography is enabled by operating an operating member such as a dedicated strobe lever. At this time, some cameras emphasize the strobe photography mode by making the strobe light emitting part pop out from within the camera body, which is called pop-up.

Therefore, in order to take pictures with a strobe, it is necessary to operate special parts such as a strobe lever, and due to the mechanism and design, this lever is small and
It is difficult to operate while looking into the viewfinder. Furthermore, if the strobe light emitting section is made to protrude to emphasize the strobe photography mode, a mechanism and space for this purpose will be required, making the structure complicated. Furthermore, the display in the viewfinder of the strobe photography mode cannot be easily displayed.

[Problem that the invention attempts to solve]

As described above, conventional cameras with a built-in strobe flash require small special members such as levers in order to perform strobe photography, making it difficult to operate the camera while looking through the viewfinder. Furthermore, if the strobe light emitter for emphasizing the strobe photography mode is made to protrude, the structure becomes complicated. Furthermore, it is not possible to easily display the strobe photography mode in the viewfinder.

Therefore, the present invention was proposed to solve these conventional problems, and it simplifies operation by omitting the dedicated lever for strobe photography, makes it easy to emphasize strobe photography, and improves the image quality of the front view. To provide a camera with a built-in strobe flash which can easily display a strobe photography mode inside the camera.

[Means for solving problems]

In order to achieve the above-mentioned object, the camera according to the present invention includes a camera body incorporating a photographic optical section equipped with an imaging lens, a viewfinder section, a strobe display lighting section, and a fixed strobe flash section;
An optical system protection plate provided on the front surface of the camera body so as to be freely movable in parallel; a non-use mode position in which the photographing optical section and the viewfinder section of the camera body are closed; and a normal photographing mode position in which the photographic optical section and the viewfinder section are opened. The position of the optical system protection plate is selectively regulated at three positions: a mode position, a strobe photography mode position that opens the photographic optical section, the viewfinder section, and the strobe display lighting section, and makes the strobe flash usable. The optical system is configured to switch between a non-use mode, a normal photography mode, and a strobe photography mode by moving the optical system protection plate.

[Effect]

In the camera according to the present invention, when the optical system protection plate is moved one step in parallel from the non-use mode position where the photographing optical part and the viewfinder part of the camera body are closed, the photographic optical part and the viewfinder part are opened. The camera enters the shooting mode and moves further from this normal shooting mode position.
When the step parallel movement is performed, the strobe flash becomes usable and the strobe photography mode is selected.

Further, when the optical system protection plate is operated to move in the opposite direction to the above operation, the normal photography mode and the non-use mode are sequentially selected from the strobe photography mode.

〔Example〕

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

The camera according to the present invention is applied to a so-called strobe built-in camera, which has a photographic optical section, a viewfinder section, a strobe display lighting section, and a fixed strobe flash section built into the camera body 1. A front part 10 of the main body 1 faces a lens 12 constituting a photographing optical part, a viewfinder 11 of a viewfinder part, and a strobe window 4 for guiding light from a fixed strobe flash part.

Further, a shutter button 13 is protruded from one end of the upper surface side of the camera body 1.
A groove 15 for supporting the optical protection plate 2 so as to be movable in parallel to the front surface 10 of the camera body 1 is provided at a position closer to the front surface 10 of the camera body 1 on the upper surface side.

The upper and lower ends of the optical system protection plate 2 are folded back into a U-shape, and the U-shaped portion 16 fits into the groove 15, and the optical system protection plate 2 cannot be separated from the camera body 1. It is attached so as to be freely movable in parallel in the direction of the groove 15. Note that this groove 15 and the U-shaped portion 1
6 is also located at the bottom of the camera body 1, but is omitted in the drawing.

Next, a mechanism for regulating the parallel movement of the optical system protection plate 2 into three positions will be explained with reference to FIG. 2.

Three click grooves 26 are provided in the central part of the back side of the optical system protection plate 2 in a line in the moving direction of the optical system protection plate 2. A click ball 9 is provided at one end of the click plate spring 8, and the other end is provided with a main body front portion 10.
Fixed. The click ball 9 and one of the click grooves 26 are fitted together by the pressure of the leaf spring 8, and the position is regulated. Therefore, in the lateral direction, it is possible to move two steps by the distance between the click grooves 26.

Similarly, referring to FIG. 2, the optical system protection plate 2
The mechanism by which the strobe window 3 opens in conjunction with the movement of the strobe window 3 to the second stage will be explained.

Optical system protection plate pins 2a are installed on the back peripheral edge of the optical system protection plate 2. Conversion lever 6
has a support shaft 17 and a conversion lever hole 18, this support shaft 17 is fixed to the front part 10 of the main body, and the conversion lever 6
can be rotated. The strobe window cover 5 has a strobe window cover pin 5a at one end, and the strobe window cover pin 5a and the conversion lever hole 18 allow
The strobe window cover 5 and the conversion lever 6 are connected. The support shaft 17 of the conversion lever 6 is provided with a conversion lever spring 7.

The moving direction of the second stage of the optical system protection plate 2 is the direction of arrow A, and when the optical system protection plate 2 moves in this direction, the optical system protection plate pin 2a pushes one end of the conversion lever 6, As a result, the conversion lever 6 rotates around the support shaft 17, and the rotation is converted into linear movement by the connection between the conversion lever hole 18 and the strobe cover pin 5a, and the strobe window cover 5 The camera moves in direction B, and the strobe window 3 opens.

When the optical system protection plate 2 is moved in the opposite direction to the second movement, the optical system protection plate 2 moves in the opposite direction to the arrow A, the force of the optical system protection plate pin 2a pushing the conversion lever 6 disappears, and the support shaft Due to the restoring force of the conversion lever spring 7 attached to the lever 17, the strobe window cover 5 moves in the direction opposite to arrow B, and the strobe window 3 is closed. In this way, the strobe window 3 is opened and closed in conjunction with the movement of the optical system protection plate 2 to the second stage.

The camera of the present invention can be set in a non-use mode, a normal use mode, etc. by moving the optical system protection plate 2 in the lateral direction.
You can switch between three strobe photography modes. The respective modes are shown in Figures 3 and 4.
It is shown in FIG.

FIG. 3 is a front view showing the non-use mode state. At this time, the lens 12, the viewfinder 11, and the strobe display lighting window 4 are covered by the optical system protection plate 2, so that when the camera is not used, the optical system is protected and the strobe window 3 also remains closed.

FIG. 4 is a front view showing the normal photographing mode, in which the optical system protection plate 2 is moved one step and is regulated in position by the above-mentioned position regulation mechanism. At this time, the lens 12 and the viewfinder 11 are exposed, the strobe display light window 4 is covered with the optical system protection plate 2, and the strobe window 3 is closed. This allows normal photography without using a strobe.

FIG. 5 is a front view showing the strobe photographing mode, in which the optical system protection plate 2 is regulated in position by the above-mentioned position regulation mechanism at a position moved by two steps. At this time, the lens 12, the viewfinder 1
1, the strobe display lighting window 4 appears, and the flash photography mode is displayed in the viewfinder 11 by the light taken in from the strobe display lighting window 4. At the same time, the strobe window 3 opens in conjunction with the movement to the second stage, thereby enabling strobe photography. Note that the opening of the strobe window 3 in conjunction with the movement of the second stage emphasizes strobe photography.

By the way, in the above embodiment, the optical system protection plate 2
Although a concave portion 14 is provided to improve the grip of fingers and improve operability, other shapes, such as a wave shape, can also be used to improve operability.

In addition, in order to use the strobe, it is necessary to open and close the contacts of the electric circuit in conjunction with the movement of the optical system protection plate 2, but this is due to the movement of the optical system protection plate 2 or the strobe window cover 5. A detailed explanation will be omitted since it is sufficient to construct a switch that can open and close the contacts by using this.

[Effect of idea]

As mentioned above, the present invention provides a so-called built-in strobe camera, which has a photographic optical section, a viewfinder section, a strobe display lighting section, and a fixed strobe flash section built into the camera body. The protective plate is attached so that it can be moved in parallel on the camera side, and the protective plate is selectively restricted to three positions: the non-use mode position, the normal photography mode position, and the strobe photography mode position. By selectively moving parallel to the position, you can freely select the non-use mode, normal shooting mode, and strobe shooting mode, and you can use the strobe only by moving the optical system protection plate, so it is possible to use the strobe. There is no need to provide a dedicated lever or the like, and the mechanism can be simplified.

In addition, the optical system protection plate is located on the front of the camera body and opens and closes the lens of the photographic optical section, the viewfinder, the strobe display lighting section, and the strobe window, so it is large and easy to operate. , it becomes possible to reliably select each operation mode according to the movement position.

In particular, as in the above-mentioned embodiment, by opening the strobe window in conjunction with the movement of the second stage of the optical system protection plate, the use of the strobe can be emphasized. By making the strobe display lighting window appear, the strobe use mode can be easily displayed in the viewfinder using the light taken in from the strobe display lighting window.
