[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera, and more particularly, to a structure of a flash light emitting device in which a light emitting portion moves.

[0002]

2. Description of the Related Art Heretofore, various flash light emitting devices have been proposed in which a light emitting portion moves in a direction away from a lens of a camera in order to prevent a red eye phenomenon in which a pupil of a person appears red. For example, as shown in FIG. 18, Tokuhyo Hei 4-505516, the distance between the lens and the light-emitting portion is increased by flipping up the light-emitting portion 100 of the strobe, which is housed so as to cover the lens of the camera, at the time of use. To avoid the red-eye effect.

Further, the actual Kaihei 53-26145 is shown in FIG.
As shown in FIG.
A method of separating the light emitting unit 201 from the lens by 0 is disclosed.

[0004]

However, in the above Japanese Patent Publication No. 4-505516, the lens and the light emitting unit 100 are not provided.
The distance between them is determined by the size of the camera and cannot be made large. In particular, when a camera is downsized using a small-sized patrone film as recently proposed, the distance between the lens and the light emitting part cannot be increased, and the possibility of the red-eye phenomenon is further increased. Will end up.

Further, in the above-mentioned SAI 53-26145, when the arm 200 is carried while the arm 200 is extended, the light emitting portion 201 bumps against it, and when an external force is applied, the arm 200, the light emitting portion 201, or the camera. The side may be damaged.

An object of the present invention is to increase the distance between the lens and the light emitting portion in a flash light emitting device incorporated in a small camera body, and to apply an external force with the light emitting portion separated from the lens. Is to provide a camera that does not damage the arm, the light emitting part, or the camera.

[0007]

In order to achieve the above object, a camera according to the present invention comprises a camera body,
The light emitting device is configured to be attachable / detachable to / from the camera body, and at least a part of the connecting means that connects the camera body and the light emitting device is flexible.

[0008]

First Embodiment A first embodiment of the present invention will be described first. 1 and 2, reference numeral 1 is a camera body, 2 is a light emitting portion of a strobe forming a light emitting device, 3 is a flexible arm having flexibility as a connecting member, and FIG. 1 is a light emitting portion of the strobe. FIG. 2 is a diagram showing a state in which 2 is not projected, and FIG. 2 is a diagram showing a state in which the light emitting unit 2 of the strobe is projected.

Although the flexible arm 3 is a coil spring in this embodiment, it may be a single steel wire which is not in a coil shape as long as it has flexibility, a resin such as plastic, or a rubber. good. Reference numeral 4 is a guide of the flexible arm 3 that works when moving the light emitting unit 2.

Although not shown in the figure, the stroboscope control board is placed in the space surrounded by the arms 3 for better space efficiency. Further, it may be housed in the light emitting unit 2.
Further, a main capacitor for accumulating electric charges required for light emission may be housed in the light emitting section 2. Here, the control plate and the light emitting unit 2 are electrically connected via the inside of the arm 3.

The light emitting section 2 can be moved by the photographer manually, by using a motor or an electromagnet, by using the force of a spring or rubber, or by moving the camera. The force for moving the lens may be transmitted to a lever, a cam, or the like for movement. In addition, when storing, a motor, electromagnet, spring,
Needless to say, the force of moving the lens of the rubber or the camera may be used to move the lens. Although a strobe is used as the light emitting device in this embodiment, it goes without saying that a light source means such as a simple lamp that does not emit flash light may be used.

When the light emitting portion 2 is moved downward from the projecting state, the arm 3 has flexibility, so that the arm 3 is bent along the guide 4 and is housed. Since the arm 3 is bent and housed in a U shape, the light emitting unit 2 can be projected by an amount equal to or more than twice the dimension of the camera in the height direction. Further, since the arm 3 can be integrally formed, there is an effect of cost reduction.

A second embodiment of the present invention will be described below. FIG. 3 shows a state in which the light emitting portion 2 of the strobe is not projected, and in this embodiment, the arm 3 is folded and stored from the side portion to the bottom portion of the camera body.

Since the arm 3 is bent and accommodated from the side portion to the bottom portion of the camera body, the light emitting portion 2 can be projected by an amount three times or more the dimension in the height direction of the camera. Also in this embodiment, as in the first embodiment, the control board and the main capacitor may be appropriately arranged on the light emitting unit side. Further, in this embodiment, the arm 3 is formed along the two sides of the camera, but if the arms 3 are arranged along the three sides and four sides, a larger amount of protrusion can be obtained.

The third embodiment of the present invention will be described below. FIG. 4 shows a state in which the light emitting unit 2 of the strobe is not projected, and FIG. 22 shows a state in which the light emitting unit 2 is moving. Reference numeral 5 is a fixing member for fixing the end portion of the arm 3, and since the end portion of the arm 3 is fixed,
The bent portion of the arm 3 moves as the light emitting unit 2 moves upward, and finally the shape shown in FIG. 10 is obtained.

Also in this embodiment, as in the first embodiment, the control board and the main capacitor may be appropriately arranged on the light emitting portion side. The fourth embodiment of the present invention will be described below. FIG. 5 shows a state in which the light emitting unit 2 of the strobe is not projected, and FIG. 6 is a view showing a state in which the light emitting unit 2 is projected. Reference numeral 6 denotes a steel plate, which is curved so that a cross section perpendicular to the direction extending from the camera body 1 has an arc shape. The steel plate 6 can sufficiently support the light emitting unit 2 in the stretched state.

As the light emitting section 2 moves downward, the arm 6 bends along the guide 4 and is housed in the shape shown in FIG.
Here, the arm 6 is stored in a round shape by using the guide 4, but a winding shaft may be used and the arm 6 may be wound by rotating this.

Also in this embodiment, as in the first embodiment, the control board and the main capacitor may be appropriately arranged on the light emitting portion side. The fifth embodiment of the present invention will be described below. FIG. 7 shows a state in which the stroboscopic light emitting portion is not projected, and FIGS. 8A and 8B are a front view and a side view, respectively, in a state in which the light emitting portion 2 is projecting. Reference numeral 2 is a light emitting portion, 8 is an arm made of a rigid body such as a mold, 7 is a fulcrum of rotation of the arm, and 9 is a coil spring provided in the middle of the arm 8, and the light emitting portion 2 and the arm are provided with the arm 8 extended. When an external force is applied to 8, it has the role of releasing the force. Although the coil spring 9 is used in this embodiment, a resin such as plastic or rubber may be used as long as it has flexibility.

Also in this embodiment, as in the first embodiment, the control board and the main capacitor may be appropriately arranged on the light emitting portion side. As a sixth embodiment of the present invention, an example of a method of processing a lead wire connecting a light emitting section and a control circuit will be shown below.

20 and 21 are diagrams for explaining a conventional method of processing a lead wire by a pop-up method. 20 shows a state in which the light emitting unit 2 is not projected, and FIG. 21 is a diagram showing a state in which the light emitting unit 2 is projected. 3 is a rigid arm such as a mold, 1
Reference numeral 0 is a strobe control circuit board, and 11 is a lead wire for connecting the light emitting unit 2 and the control circuit board 10 through the arm 3.

As can be seen from the figure, the lead wire 11 corresponds to the moving amount of the light emitting part 2 when the light emitting part 2 is housed,
It has slack. For this reason, the lead wire 11 may move along with the movement of the light emitting portion 2 and may be caught by an electric component arranged on the control circuit board 10 to hinder the movement of the light emitting portion 2, or the lead wire 11 may be broken. . Further, the slack of the lead wire 11 does not contribute to the pop-up amount of the light emitting unit 2 and is wasteful.

In order to solve this problem, the sixth embodiment has the following configuration. FIG. 9 shows a state in which the light emitting unit 2 is not projected, and FIG. 10 is a diagram showing a state in which the light emitting unit 2 is projected. 3 is a hollow tubular flexible arm, 5 is a fixing member for fixing the end of the arm 3, 1
Reference numeral 0 is a strobe control circuit board, and 11 is a lead wire for connecting the light emitting section 2 and the control circuit board 10 through the arm 3.

As can be seen from the figure, the lead wire 11 has no unnecessary slack and is guided by the arm 3, so that it does not get caught on the internal structure such as an electric component. . Further, the length of the lead wire 11 contributes entirely to the pop-up amount of the light emitting section 2, so that there is no waste.

In addition, the flexible arm 3 itself may be made of a conductive member and used instead of the lead wire 11. Also in this embodiment, as in the first embodiment, the control board and the main capacitor may be appropriately arranged on the light emitting unit side.

Next, as a seventh embodiment, another example of the lead wire processing will be described. FIG. 11 shows a state in which the strobe light emitting portion is not projected, and FIG. 12 is a diagram showing a state in which the strobe light emitting portion 2 is projected. Reference numeral 10 is a strobe control circuit board, 13 is a battery serving as a power source for the strobe circuit, and the camera body has a separate battery. Reference numeral 12 is an integrated flash unit including these components, 14 is a light receiving element for receiving a light emission trigger signal, and 15 is a light emitting element provided on the camera body side for transmitting a light emission trigger signal.

As described above, the stroboscopic light emitting section 2 is independent and integrated, and the signal transmission is light emitting and wireless using the light receiving element, so that it is not necessary to pass the lead wire through the arm 3. Although light is used here for transmitting signals, electromagnetic waves or sound waves may be used.

Although the examples of the strobe built into the camera have been shown so far, naturally these structures can be similarly applied to a single strobe. Also in this embodiment, as in the first embodiment, the control board and the main capacitor may be appropriately arranged on the light emitting unit side.

The eighth embodiment of the present invention will be described below. In the seventh embodiment, an example in which a signal is wirelessly transmitted between the strobe and the camera by using a light emitting element and a light receiving element has been shown, but if so, a completely free strobe having no arm may be considered.

Since there is no means for restricting the position between the camera and the strobe, it is possible to place the strobe near the subject, aim for a special effect by holding it with the hand, and use it for preventing red eye. Also, because it is wireless, there is no need to prepare a special strobe contact on the camera side, so the structure of the camera does not become complicated, and one strobe itself can be used in common with many other cameras. Is also possible.

Besides using the strobe away from the camera, the strobe may be attached to the camera for use. In this case, it is desirable that it can be easily attached and detached and that it can be attached to various cameras.

The method will be described below. In FIG.
Reference numeral 12 is a wireless strobe, 1 is a camera body, and a Bencro tape 16 is attached to the bottom of the wireless strobe 12. Bencro tape 1 on top of the camera
7 is attached. These tapes are not attached to the flash or camera from the beginning, but the user attaches them with double-sided tape attached to the back of the tape.

FIG. 14 is a view showing a state in which the strobe is attached to the camera body 1, and 14 is a light receiving element for receiving a light emission trigger signal, which receives the fact that the built-in strobe 18 emits light and receives the wireless strobe 12. Light up.

Although the built-in strobe light is received here, a light emitting LED for AF or an LED for self-timer display may be used, and in addition to light, for example, a light emitting circuit of the built-in strobe 18 may be used. The electromagnetic induction of the included trigger transformer may be received, or similarly, the electromagnetic induction or sound of the shutter motor or coil may be received.

In this embodiment, the Bencro tapes 16 and 1 are used.
Although 7 was used, 16 may be a magnet, 17 may be a thin metal plate, 16 may be double-sided tape, 17 may be used directly and a strobe may be directly attached to the camera, The wireless strobe 12 may be attached directly to the camera body 1 by using 16 as an adhesive rubber.
As shown in FIG. 5, the wireless strobe 12 may be directly attached to the camera body 1 by providing a suction cup 19 on the strobe side. At this time, if the flatness on the camera side cannot be expected,
A thin plastic plate having excellent flatness may be attached like the Bencro tape 17.

Also in this embodiment, as in the first embodiment, the control board and the main capacitor may be appropriately arranged on the light emitting portion side. The ninth embodiment of the present invention will be described below. FIG. 16 shows a state in which the wireless strobe is attached to the camera. Reference numeral 12 denotes a strobe body, which is attached to the camera by a clip-shaped arm 20 having 21 as a fulcrum so as to directly sandwich the camera. Although the clip has a built-in spring at the fulcrum 21, it may be attached using the elasticity of the arm itself without providing the fulcrum 21.

In addition, it is possible to use the clip by attaching it to a piece of wood, a tripod, a collar of a photographer's hat, etc. other than the camera. Also in this embodiment, as in the first embodiment, the control board and the main capacitor may be appropriately arranged on the light emitting unit side.
