The finger grip 40 for the little finger is inserted into the bearing 50 and is rotatably held by the base 32, and is urged by a spring 51 in a direction away from the camera body 12. And the finger grip 40 for little fingers is fixed by screwing the female screw 52 into the screw hole 50a.

  A grip cover 60 is provided so as to cover these finger grips 34, 37, and 40. The grip cover 60 is formed of a flexible material such as rubber or resin, for example, and its end is bonded to the base 32 and attached to the camera body 12. The grip cover 60 has a function of pressing the finger grips 34, 37, and 40 that move away from the camera body 12 by the bias of the springs 45, 48, and 51 when the female screws 46, 49, and 52 are loosened. ing. The grip cover 60 has an upper step bonded to the middle finger finger grip 34, an intermediate step bonded to the ring finger finger grip 37, and a lower step bonded to the little finger finger grip 40, and each finger grip 34, 37, 40 is attached to the camera. When it is moved to the inside of the main body 12, it is deformed along with this movement.

  An opening 64 that can be opened and closed by a detachable cap 63 is provided in the upper part of the grip cover 60, and the cap screw 46 is exposed by removing the cap 63. The position of the finger grip 34 for the middle finger can be adjusted by loosening the screw 46 from the opening 64 and moving the finger grip 34 for the middle finger and then tightening the finger screw 46. Similarly, an opening 67 is provided in the middle part of the grip cover 60, and the cap screw 49 is exposed by removing the cap 66. And the position of the finger grip 37 for ring fingers can be adjusted by following the same procedure as the finger grip 34 for middle fingers. Further, an opening 70 for exposing the female screw 52 is provided in the lower part of the grip cover 60, and the position of the finger grip 40 for the little finger can be adjusted by removing the cap 69.

  As the grub screws 46, 49, 52 used for adjusting the positions of the finger grips 34, 37, 40, those of the same standard are used. The camera 10 is attached with a tool 72 for rotating the grub screws 46, 49 and 52. The tool 72 is attached to, for example, a strap (not shown) or the like of the camera 10 so that the tool 72 is prevented from being lost and can be adjusted at the destination.

  The operation of the present invention having the above configuration will be described below. A handgrip 30 that is gripped by the photographer is provided on the side of the camera body 12. The photographer takes a picture by holding the hand grip 30 with the front middle finger, ring finger, little finger, and rear thumb, and pressing the shutter button 22 with the index finger.

  If the shape of the handgrip 30 does not meet the photographer's preference, the shape of the handgrip 30 can be adjusted. When adjusting the grip shape of the middle finger, the cap 63 is removed, the arm screw 46 is loosened by using the tool 72, the finger grip 34 for the middle finger is moved to a desired position, and then the arm screw 46 is tightened. Similarly, when the grip shape of the ring finger is adjusted, the cap 66 is removed, the tube screw 49 is loosened, the ring finger finger grip 37 is moved to a preferred position, and then the tube screw 49 is tightened. In order to adjust the grip shape of the little finger, the cap 69 is removed, the thumb screw 52 is loosened, the little finger finger grip 40 is moved to a desired position, and then the thumb screw 52 is tightened.

  As described above, the camera 10 can adjust the shape of the hand grip for each finger of the photographer by moving the finger grip for each finger, and thus has a high degree of freedom of adjustment. In addition, it is not necessary to remove the hand grip or heat it to a high temperature during adjustment, and the adjustment can be easily performed with a simple operation using screws.

  In the present invention, a hand grip is constituted by a plurality of finger grips corresponding to each finger of the photographer, each finger grip is movably provided so as to correspond to the movement of the photographer's finger, and each finger grip is moved. It is only necessary to adjust the shape of the handgrip. For this reason, a handgrip of a different form from the above-mentioned embodiment can also be constituted.

  For example, in the above embodiment, the example has been described in which the three finger grips for the middle finger, the ring finger, and the little finger have the same shape, but the shape of the three finger grips is set to the corresponding finger length, etc. It may be different depending on the situation. In this case, it is conceivable that the finger grip for the ring finger is formed slightly smaller than the finger grip for the middle finger, and further, the finger grip for the little finger is formed slightly smaller than the finger grip for the ring finger.

  In the above-described embodiment, an example in which the three finger grips for the middle finger, the ring finger, and the little finger are all rotated about the common axis has been described. However, each finger grip is rotated about a different axis. It may be. It can also be said that the angle of this axis is different for each finger grip. The position and angle of the axis of each finger grip may be appropriately selected according to the position of the joint of the photographer's finger and the moving direction of the finger. Furthermore, although the example of providing three finger grips for the middle finger, the ring finger, and the little finger has been described, a finger grip for the thumb or index finger may be provided in addition to these.

  Moreover, in the said embodiment, although demonstrated by the example which fixes all the finger grips by a moving screw with a destination screw, this invention is not limited to this. For example, a finger grip provided with only a spring that is biased toward a method of moving away from the camera body is used, and a pressure detection type push switch is provided behind the finger grip. Then, by moving the finger grip so as to be pushed into the camera body side, the camera operation such as shutter release or zoom operation may be performed.

  In particular, since the index finger is often used for shutter release, when a finger grip for the index finger is provided, it is preferable that the finger grip be used as a shutter button without being fixed. Of course, the functions of various operation buttons other than the shutter button may be assigned to the finger grip. Whether or not to fix the finger grip and the function assigned to the finger grip that is not fixed may be determined as appropriate according to the specifications of the camera.

  Furthermore, in the said embodiment, although the example which fixes a finger grip by tightening a grub screw to a bearing was demonstrated, you may make it fix a finger grip by methods other than this. As a fixing method of the finger grip, for example, it is conceivable to screw the end portion on the opposite side to the bearing to the camera body. It is also conceivable that a spacer is provided between the finger grip and the camera body and the thickness of the spacer is changed. In this case, the force gripped by the photographer moves the finger grip to a position corresponding to the thickness of the spacer and changes the shape of the hand grip.

  Moreover, although the said embodiment demonstrated in the example in which each finger grip was comprised from one movable member, you may comprise a finger grip from several movable members. In this case, for example, as shown in FIG. 3, one finger grip 90 may be configured from four movable members 80, 82, 84, 86.

  As shown in FIG. 3A, the movable member 80 includes a bearing 80a and a shaft 80b provided in directions orthogonal to each other. The movable member 80 is rotatably supported by the camera body 12 by inserting a shaft 79 erected on the base 32 into the bearing 80a. The movable member 82 includes a bearing 82a and a shaft 82b that are parallel to each other. The movable member 82 is rotatably held by the shaft 80a of the movable member 80 being inserted into the bearing 82a. Similarly, the movable member 84 includes a bearing 84a and a shaft 84b that are parallel to each other, and the shaft 82b of the movable member 82 is inserted into the bearing 84a and is rotatably held. The movable member 86 includes a bearing 86a, into which the shaft 84b of the movable member 84 is inserted and held rotatably.

  In this way, as shown in FIG. 3B, the finger grip 90 not only bends in three steps in the horizontal plane, but also rotates in the vertical direction as a whole, so it moves with the same degree of freedom as the photographer's finger it can. And the shape of a hand grip can be adjusted more finely by comprising a hand grip using a plurality of such finger grips 90.

  Furthermore, in the above-described embodiment, an example in which a finger grip having a central concave shape is used for the vertical cross section has been described. For example, as shown in FIG. 4A, the vertical cross section becomes wider upward. You may comprise a hand grip using the formed finger grip 100. FIG. Further, as shown in FIG. 5B, the hand grip may be configured by using a finger grip 110 provided with a holder 110a for wrapping a photographer's finger from the outside. Of course, by dividing the finger grips 100 and 110 into a plurality of movable members and connecting the divided movable members so as to freely rotate, the degree of freedom of adjustment can be increased.

  Further, in the above embodiment, the example in which the hand grip is configured from the rotatable finger grip has been described, but the hand grip may be configured from the slidable finger grip as in the camera 120 illustrated in FIG. 5. . As shown in FIG. 5A, the camera 120 is provided with a hand grip 124 on the front side of the camera body 122. The hand grip 124 includes three finger grips 126 for the middle finger, the ring finger, and the little finger. Each finger grip 126 is formed in a substantially triangular shape whose horizontal cross section is enlarged toward the side end portion of the camera main body 122, and the tip of the photographer's finger is applied.

  As shown in FIG. 5B, each finger grip 126 is formed with a bearing 126a. In addition, on the front surface of the camera body 122, a shaft 130 that slides along the elongated hole 128 by a known slide mechanism is provided. Each finger grip 126 has a shaft 130 inserted through a bearing 126 a and is slidably supported by the camera body 122. Furthermore, each finger grip is rotatably supported on the shaft 130. In the camera 120, the shape of the hand grip 124 can be adjusted by sliding and rotating each finger grip 126 and moving the finger grip 126 to a position desired by the photographer.

  Further, like the camera 140 shown in FIG. 6, the hand grip is constituted by a finger grip that slides in the front-rear direction of the camera body 142 so as to change the depth of the depression for placing the tip of the photographer's finger. It is also possible to do. As shown in FIG. 6A, the camera 140 is provided with a hand grip 144 on the front side of the camera body 142. The hand grip 144 is composed of three finger grips 146 for middle finger, ring finger, and little finger, and each finger grip 146 is attached to the front of the camera body 142 by a spring (not shown) provided at the back. It is energized. Then, as shown in FIG. 7B, each finger grip 146 is pushed back to the inside of the camera main body 142 when the photographer holds it, and the shape of the hand grip 144 changes.
