Abstract

PURPOSE:To almost accord the direction of the force for supporting a camera with the direction of the force for carrying out releasing operation and to prevent camera moving by arranging a release operating member on a second plane and arranging a positioning member for sandwiching an image pickup device at the position which corresponds to the release operating member on a first plane. CONSTITUTION:The release operating member 4 is positioned on a second plane, and the positioning member 5 for sandwiching the image pickup device is positioned at the position which corresponds to the release operating member 4 on a first plane. A photographer depresses the bottom plane of the camera main body 1 (the plane provided with a hold 5 for thumb) with his thumb, and other fingers are put on the top plane of the camera main body 1 (the plane provided with the release operating member 4) for holding the camera. The releasing operation is carried out by depressing the releasing button 4 by using the fingers positioned on the top plane of the camera main body 1. Since the hold 5 for thumb is provided on the bottom plane of the camera main body 1, the force applied for the releasing operation operates against the thumb, and it merely operates as the force to rotate the camera main body 1. Thus, the camera moving is not easy to be occurred.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to various imaging devices such as cameras, and particularly relates to the position of a release operation member in the imaging device.

[Prior Art] FIG. 2 is a perspective view schematically showing a conventional image pickup device such as a reflex camera or a so-called compact camera.
21 is a camera body, 22 is a photographic lens, 23 is a finder window, 24 is a grip for holding the camera, 2
5 is a release button. Further, the arrow in the figure indicates the direction of incidence of the photographing light.

As shown in Figure 2, this type of camera holds the camera by applying forces in a plane perpendicular to the photographic optical axis, and uses the index finger, which is not involved in the camera hold, to hold the camera in a direction approximately perpendicular to the direction of these forces. The configuration is such that the release button 25 is operated, and the configuration is such that hand shake (hereinafter referred to as camera shake) is unlikely to occur during the release operation.

Next, FIG. 3 is a perspective view schematically showing a conventional video camera. In Fig. 3, 31 is the camera body, 32 is the photographic lens, 33 is the finder eyepiece, 34 is the grip for holding the camera, 35 is the strap for fixing the palm of the hand holding the camera, and 36 is the release button. It is. Further, the arrow in the figure indicates the direction of incidence of the photographing light. In a camera like the one shown in the same figure, the force applied to hold the camera by the palm and fingers is applied in a direction almost perpendicular to the optical axis, and the force applied to hold the camera by the thumb, which is not involved in holding the camera, is approximately perpendicular The release button 36 is configured to be operated in the optical axis direction, and the configuration is such that camera shake associated with the release operation is less likely to occur.

FIG. 4 is a perspective view schematically showing a conventional disc camera, in which 41 is a camera body, 42 is a photographing lens, 43 is a finder window, and 44 is a release button.

The arrow in the figure indicates the direction of incidence of the photographing light. In the camera shown in FIG. 4, use your thumb to press the back of the camera body 41 (the surface opposite to the surface where the photographic lens 42 is located), and use your other finger to press the front surface of the camera body 41 (the surface where the photographic lens 42 is located). Press to hold the camera. Release operation is on camera body 4
The direction of the operation is approximately the same as the direction of the force applied to hold the camera, and the camera moves easily with the release operation. However, the direction of movement is substantially coincident with the photographing optical axis, and the configuration is such that camera shake is unlikely to appear on the photographic film. However, cameras using 110 cartridges are prone to camera shake.

FIG. 5 is a perspective view schematically showing a camera using a conventional 110 cartridge, in which 51 is a camera body, 52 is a photographing lens, 53 is a finder window, and 54 is a release button. Note that the arrow in the figure indicates the direction of incidence of the photographing light.

In a camera like the one shown in FIG. 5, you can press the camera body 51 with your thumb.
Hold the camera by pressing the bottom surface of the camera body 51 (the surface opposite to the release button 54) and the top surface of the camera body 51 (the surface opposite the release button 54) with your other fingers. For the release operation, the user presses the finger release button 54 located on the top surface of the camera body 51. At this time, the direction of the force applied for the release operation is substantially the same as the direction of the force applied to hold the camera, and camera shake is likely to occur due to the release operation. Further, this direction is approximately perpendicular to the photographing optical axis, and the configuration is such that camera shake is likely to occur on the film surface.

Recently, so-called still video cameras that record images on floppy disks (magnetic disks) have been put into practical use, but in order to make the camera more compact, the camera lens and finder optical system are placed parallel to the video floppy disk. is advantageous.

FIG. 6 is a perspective view schematically showing a conventional electronic still camera. In FIG. 6, 61 is a camera body.

62 is a photographing lens, 63 is a finder window, and 64 is a release button. Further, 65 is a lid for loading and unloading a floppy disk (not shown) into and out of the camera body 61, and the lid 65 is opened and closed by sliding an operating lever 66. The arrow in the figure indicates the direction of incidence of the photographing light.

In the camera shown in Fig. 6, the outer diameter of the floppy disk jacket is approximately 55 mm. -x60. , the length in the photographing optical axis direction is larger than that of a camera using the 110 cartridge film. In the camera shown in FIG. 6, as in the camera shown in FIG. Hold the camera by pressing the top surface (the side where the release button 64 is). Release operation is done on camera body 6
1, press the release button 64 with your finger.

Therefore, like the camera shown in FIG. 5, the direction of the force applied for the release operation is almost the same as the direction of the force applied to hold the camera, and camera shake is likely to occur due to the release operation. This direction is approximately perpendicular to the photographing optical axis, and the configuration is such that camera shake is likely to occur on the image sensor (not shown). Further, as described above, since the length of the camera body 61 in the direction of the photographing optical axis is longer than that of a camera as shown in FIG. 5, the structure is more likely to cause camera wobbling.

[Problems to be Solved by the Invention] As described above, a camera in which the camera is held with a hand or finger in a direction substantially perpendicular to the photographing optical axis has the drawback that camera shake is likely to occur due to the release operation.

The present invention was made to solve such problems, and an object of the present invention is to provide an imaging device free from camera shake.

[Means for Solving the Problems] In order to achieve the above object, the imaging device of the present invention has a release operation member disposed on the second surface, and a release operation member on the first surface at a position corresponding to the release operation member. , which has a configuration in which a positioning member for holding the imaging device is disposed.

[Function] With the above configuration, the direction of the force for holding the camera, which is the imaging device, and the direction of the force for performing the release operation are almost the same direction, and the imaging device can be held in the same direction. By arranging the positioning member on one side, camera shake is less likely to occur.

[Embodiment] FIGS. 1(a), 1(b), and 1(c) are a top view, a side view, and a bottom view, respectively, of a camera showing an embodiment of the present invention.

In Fig. 1, 1 is the camera body, 2 is the photographing lens, 3 is the eyecup attached to the finder eyepiece for observing the subject image, and 4 is the release disposed on the top surface of the camera body 1 as a release operating member. Button 5 is a thumb hold located on the bottom surface of the camera body l. Also, 5
A is a thumb positioning convex portion provided on this thumb holder 5. Further, in the figure, an arrow indicates the direction of incidence of photographing light.

In the above configuration, the photographer holds the camera by pressing the bottom surface of the camera body l with his thumb (the surface with the thumb hold 5) and pressing the top surface of the camera body l with his other fingers (the surface with the release button 4). do. The release operation is performed by pressing the release button 4 with a finger located on the top surface of the camera body 1. Therefore, the direction of the force applied for the release operation and the direction of the force applied for holding the camera are substantially the same, and are substantially perpendicular to the photographing optical axis. However, by providing the thumb holder 5 on the bottom surface of the camera body l, the thumb is naturally placed in a position facing the release button 4, and the force applied for the release operation acts on the thumb, and the camera Since it hardly acts as a force to rotate the main body 1, camera shake is extremely unlikely to occur.

FIGS. 7(a), (b), and (c) are a top view, a side view, and a bottom view, respectively, of a camera showing another embodiment of the present invention. In the figures, the same parts as in FIG. 1 are the same. It is numbered.

In FIG. 7, reference numeral 1a indicates a recess provided on the lower surface of the camera body l corresponding to the release button 4, and indicates the position where the thumb comes into contact. In the embodiment shown in FIG. 7, the thumb is located on the bottom surface of the camera body l corresponding to the release button 4, so the force applied for the release operation acts on the thumb, and the force to rotate the camera body l is Since it hardly works, there is no camera shake, and the first
An effect similar to that of the embodiment shown in the figure can be obtained.

[Effects of the Invention] As explained above, the imaging device of the present invention has a release operating member arranged on the second surface, and a mechanism for holding the imaging device at a position corresponding to the release operating member on the first surface. Since the positioning member is arranged, the direction of the force for holding the camera and the direction of the force for performing the release operation are almost the same, making it difficult for camera shake to occur.
