Abstract

PURPOSE:To prevent camera moving by permitting the operating direction of a release operating member to be almost orthogonal to the direction of the force applied so as to hold a camera for the camera which is used by being held from both its top and the bottom. CONSTITUTION:The title device is composed by positioning the release operating member 4 which carries out the release operation by shifting along on a first plane which is almost parallel to the projecting axis of the light projected from an object. A photographer puts his thumb on the bottom plane of the camera main body 1 (the plane provided with a hold 5 for thumb) and supports the camera, 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 sliding the releasing button 4 upward (or downward) by using one of those fingers put on the top plane of the camera main body 1. Thus, the force applied for the releasing operation operates almost orthogonal to the force applied for holding the camera main body, and the camera rocking is not easy to be occurred.

Description

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

[Prior Art] FIG. 2 is a perspective view schematically showing a single-lens reflex camera or a so-called compact camera as a conventional imaging device.
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.

:jS2 [As shown in J, this type of camera holds the camera by applying forces in a plane perpendicular to the photographing optical axis, and then holds the camera in a direction approximately perpendicular to the direction of these forces with the index finger that is not involved in holding the camera. 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 hand that holds the camera, and 36 is the strap for fixing the camera. It's the release button. 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 is configured to be operated in the optical axis direction, making it more difficult for camera shake to occur due to the release operation.

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, press the back of the camera body 41 with your thumb (the surface opposite to the surface where the photographic lens 42 is located), and use your other fingers 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 this operation is almost the same as the direction of the force applied to hold the camera, and the camera easily moves 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 the 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 surface where the release button 54 is located) and the top surface of the camera body 51 (the surface where the release button 54 is located) with your other fingers. The release operation is performed by pressing the release button 54 with a finger located on the top surface of the camera body 51. At this time, the direction of the force applied for the release operation is approximately the same as the direction of the force applied to hold the camera. Camera shake is likely to occur due to 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, and in order to make the cameras 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 taking in and out a floppy disk (not shown) into and out of the camera body 61, and an operation lever 66
The lid 65 is opened and closed by sliding. 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. Therefore, 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.
4) and the top surface of the camera body 61 (the surface where the release button 64 is located) with other fingers to hold the camera. Release operation is done on camera body 61
Press the release button 64 with the finger located on the top surface.

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 substantially perpendicular to the photographing optical axis, and is configured to easily cause camera shake on the image sensor (not shown). Furthermore, as described above, since the length of the camera body 61 in the direction of the photographing optical axis is longer than that of the camera shown in FIG. 5, the configuration is more likely to cause camera shake.

[Problems to be Solved by the Invention] As described above, a camera in which the camera is held with a finger in a direction substantially perpendicular to the photographing optical axis has the disadvantage 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, an imaging device of the present invention has a first surface and a second surface that are substantially parallel to the projection optical axis of light incident from a subject. , in an imaging device that holds the first surface and the second surface by sandwiching them, a release operation member that performs a release operation by moving along the first surface is arranged. It has a structure.

[Function] Since the present invention is configured such that the release is performed by sliding in a direction substantially parallel to the photographing optical axis of the camera, which is an imaging device, camera shake associated with the release operation 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 a camera body, 2 is a photographing lens, 3 is an eyecup attached to the finder eyepiece, and 4 is a release button as a release operation member arranged on the top surface of the camera body l. a) Inside, it can be slid up and down. Reference numeral 5 denotes a thumb holder placed on the lower surface of the camera body 1. The arrow in the figure indicates the direction of incidence of photographing light.

In the above configuration, the photographer places his or her thumb on the bottom surface of the camera body 1 (the surface with the thumb holder 5) to support the camera, and places the other finger on the top surface of the camera body 1 (the surface with the release operation member). and hold the camera. The release operation is performed by sliding the release button 4 upward (or downward) in FIG. 1(a) with any finger placed on the top surface of the camera body l. Therefore, since the force applied for the release operation acts almost at right angles to the force applied to hold the camera body l, camera shake is less likely to occur.

[Effects of the Invention] As explained above, the present invention makes the operating direction of the release operating member almost perpendicular to the direction of the force applied to hold the camera, even in a camera that is held between the top and bottom of the camera. , camera shake is less likely to occur.
