Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem wherein it is difficult for a stroboscopic device performing bounce photographing to perform easy bounce photographing when a camera is held in a vertical position. <P>SOLUTION: A junction part fixing a reflecting plate and an emitting device serves as a reflecting plate support part that is freely rotatable. A method for fixing the reflecting plate support part and the reflecting plate uses a mechanism by which the reflecting plate is easily attached or detached and is rotated at a predetermined angle around the reflecting plate support part. This makes the reflecting plate freely movable and therefore eliminates inconvenience in bounce photographing when the camera is in a vertical position. Accordingly, photographing both in a normal position and in a vertical position is easily performed. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a strobe device that can perform bounce shooting.

  Conventionally, in order to reproduce the detailed expression and color of a subject at the time of shooting using a strobe device equipped with a flash irradiation member, the flash light emitted from the irradiation device is not directly irradiated onto the subject but on the wall or ceiling. There is known a technique (so-called bounce shooting) in which light is reflected by reflecting the light on the surface and so on.

In addition, as a conventional technique using a diffusion plate, in Patent Document 1, a light beam reflected by a reflection plate is diffused and dimmed by a diffusion plate to irradiate a subject evenly without being blocked by a lens or the like. Is disclosed.
Patent Document 2 discloses a strobe device that is miniaturized so that an irradiation angle conversion adapter and a reflection plate can be housed in the upper portion of the irradiation device.

  However, in Patent Document 1, since the diffusion plate and the reflection plate are formed on the same member and the diffusion plate is pulled out to the top of the reflection plate, it is easily damaged by an external impact or the like. This can be said to be unsuitable for miniaturization because the thickness of the diffuser and the reflector must be reduced as the strobe device is miniaturized.

  In Patent Document 2, the diffusion plate and the reflection plate are separated and are suitable for miniaturization. However, there is no problem in shooting with the camera in the normal position, but in the vertical shooting, there is a problem that good bounce shooting cannot be performed because the reflecting plate is not arranged above the light emitting unit.

  A strobe device according to the present invention is provided with an irradiation device having a flash emission unit that emits flash light, and an irradiation direction variable member provided on a light emission unit side of the flash emission unit, and the irradiation direction variable member emits light from the flash emission unit. In the strobe device that directs a part of the luminous flux to be directed in an arbitrary direction, the irradiation direction variable member is held by a support portion that is rotatable substantially perpendicular to the irradiation device at a relay portion with the strobe body. It is characterized by being.

  According to the present invention, it is possible to easily perform bounce shooting in a vertical position by a camera that has been unsuitable in the past by providing a reflector that can be freely changed to an arbitrary angle desired by the photographer. In addition, there is an advantage that a reflector having a simpler structure, less expensive and stronger than the conventional apparatus can be mounted. In addition, bounce shooting can be easily performed, and shooting capable of faithfully reproducing the expression and color can be performed, so that an optimum image can be obtained.

Example 1
Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view showing an embodiment of a strobe device of the present invention. This figure is a diagram showing a case where direct irradiation is performed without using a reflector. A diffusing plate 2 having a Fresnel shape is rotatably mounted on the front surface of the light emitting unit of the strobe device body 1. A flash discharge tube (not shown) is disposed behind the diffusion plate 2, and when this flash discharge tube emits light, diffuse light is irradiated through the diffusion plate 2. Reflecting plate support arms 4 and 5 are attached to the upper part of the diffusing plate 2 so as to be rotatable by about 180 degrees with respect to the direction in which the light beam is irradiated. Further, rotation support portions 6 and 7 for rotatably supporting the reflection plate support arms 4 and 5 are fixed to the strobe device main body 1 side.

  FIG. 2 is a diagram showing a single structure of the reflecting plate 3. The reflecting plate 3 is provided with locking portions 3-1 and 3-2 for locking to the reflecting plate fixing arms 4 and 5. 2A is a view seen from the bottom of the reflector 3, FIG. 2-B is a view seen from the side, and FIG. 2-C is a view seen from the front. Here, the locking portions 3-1 and 3-2 are formed integrally with the reflecting plate 3 and have a substantially C-shape, and have a slight elasticity, and the opening portion has the reflecting plate support arm 4, At the time of attaching to 5, the opening portion is enlarged and the opening portion is enlarged, and is in close contact with and locked to the arm portions of the reflector support arms 4 and 5, respectively.

  After being locked, it is possible to rotate 360 degrees about the reflector support arms 4 and 5 by a predetermined load, so that a photographer can arbitrarily set an angle necessary for photographing.

  FIGS. 3 to 6 show the relationship between the reflector support arm 4 and the rotation support unit 6. In FIG. 3, a base 31-1, which is fixed to the stroboscope body 1, and an arm fixing unit on the top thereof. 31-2 is provided. The arm fixing portion 31-2 is provided with notches 3-3 and 3-3 that allow the reflector support arm retaining portions 4-1 and 4-2 to pass therethrough, and the notches 3-3 and 3- 3, the reflection plate support arm 4 is prevented from being detached and held by rotating the reflection plate support arm retaining portions 4-1 and 4-2 in the lower part of the arm fixing portion 31-2. . Reference numeral 8 denotes a retaining portion in the axial direction of the reflecting plate.

  FIG. 4 shows a state in which the reflection plate support arm 4 is fixed by the arm fixing portion 31-2. The reflection plate support arm 4 is rotated approximately 45 degrees clockwise from the position shown in FIG. State.

  FIG. 5 is a perspective view of the reflector support arm 4 at that time. FIG. 6 is a perspective view when the reflector support arm 4 in the normal position is rotated to a position corresponding to the vertical position photographing.

  In FIG. 3, the reflector support arm 4 is inserted into the arm fixing portion 31-2 because the reflector 3 is not used at the insertion position when it is actually used, and when the reflector 3 is not used. Since the other reflector supporting arm 5 is also fixed, it does not fall out of the strobe device body 1.

  Next, an actual usage pattern of the reflector will be described. FIG. 7 shows a state where the reflector 3 is used from the state where the reflector 3 is not used. As shown in the figure, the reflecting plate 3 can be rotated from the A position to the C position, and the irradiation light beam can be made variable at an arbitrary angle desired by the photographer. The reflection plate 3 can be varied from the A position to the C position with the reflection plate support arms 4 and 5 as described above as the rotation axis center, and only the movement of the reflection plate 3 under a predetermined load such as friction is taken. Can be easily operated. For this reason, it is needless to say that the range of photographing methods can be expanded since the light beam from the strobe device can be irradiated to the subject side as desired during portrait photography or close-up photography. FIG. 8 is a diagram illustrating a first state of the reflecting plate 3 and the reflecting plate support arms 4 and 5 when vertical position shooting is performed. As described above, the reflection plate 3 is held by the two reflection plate support arms 4 and 5. However, when used in vertical position shooting, the reflection plate is located on the lower side when the strobe device is held in the vertical position. It is necessary to remove the locking portion 3-2 locked to the support arm 5 from the reflection plate support arm 5.

  FIG. 8 shows a first state of the reflecting plate 3 for performing vertical position shooting when a release switch of a camera body (not shown) is held down. In FIG. 8, the holding member 3-2 may be removed from the reflecting plate support arm 5 by pulling the reflecting plate 3 upward while pressing the reflecting plate support arm 5 on the side from which the reflecting plate 3 is removed.

  The next development will be described with reference to FIG. When the locking portion 3-2 of the reflecting plate 3 is disengaged from the reflecting plate support arm 5, the reflecting plate support arm 5 is rotated 90 degrees or more in the light beam irradiation direction. This is to prevent the reflecting plate 3 from coming into contact with the reflecting plate support arm 5 (the state shown in FIG. 9A). Next, after the reflecting plate support arm 5 is rotated, the reflecting plate 3 is rotated approximately 90 degrees in the light beam irradiation direction together with the reflecting plate support arm 4 (state shown in FIG. 9B). When the reflecting plate 3 is rotated in the state of FIG. 9B, the reflecting plate 3 comes into contact with the diffusing plate 2, so that a predetermined amount of the reflecting plate 3 is drawn out in the light beam irradiation direction. FIG. 10 is a development view showing the state. The reflecting plate is pulled out from the point A to the point B, but the amount of drawing out the reflecting plate 3 is regulated by the reflecting plate retaining stopper 8 fixed to the tip of the reflecting plate support arm 4, so that the reflecting plate 3 is reflected by the reflecting plate support arm 4. It will never be missed. FIG. 11 shows a final development view. After the reflecting plate 3 is pulled out to the tip of the reflecting plate support arm 4, the reflecting plate 3 is rotated 90 degrees counterclockwise about the supporting arm 4 as a rotation center (state of FIG. 11-A). Thereafter, the reflection plate 3 is finely adjusted to a desired reflection angle (state shown in FIG. 11B).

  In this way, since the reflecting plate 3 can be changed to various angles with the reflecting plate support arm as the center of the arm fixing portion, various reflection angles can be created. The photographer can easily obtain the optimum photographing state by using the reflected irradiation light utilizing the plurality of reflection angles. In addition, it is possible to provide a stroboscopic device including a reflective plate that is inexpensive and excellent in usability without requiring a space or a complicated mechanism as compared with a conventional device.
