Shown from the side.

  The base member 601 has an opening (grip mounting portion) 6010 into which the grip member can be inserted and removed. When the grip mounting unit 60 is in the state shown in FIGS. 10A and 12A, the lock portion 6021 of the first lock lever 602 and the lock portion 6033 of the second lock lever 603 are the projection plane of the opening 6010. It is exposed inside. In the present embodiment, this state is referred to as a closed state of the grip mounting unit 60. In the closed state of the grip mounting unit 60, the first lock lever 602 is moved by the restoring force of the coil spring 604, and the surface portion 6055 of the leaf spring 605 overlaps with the engagement protrusion 6025 of the first lock lever 602, thereby The surface portion 6055 of the spring 605 is charged. When the grip mounting unit 60 is in the closed state, the first lock lever 602 and the second lock lever 603 are positioned at a locking position for locking the mounted grip.

  When the grip mounting unit 60 is in the state shown in FIG. 10B and FIG. 12B, the lock portion 6021 of the first lock lever 602 and the lock portion 6033 of the second lock lever 603 Evacuated from the projection plane. This state is called an open state of the grip mounting unit 60. In the open state of the grip mounting unit 60, the engagement protrusion 6025 provided on the first lock lever 602 engages with the notch 6051 of the leaf spring 605, and the coil spring 604 is stretched with respect to the natural state. It is charged. When the grip mounting unit 60 is in the open state, the first lock lever 602 and the second lock lever 603 are located at a release position where the engagement of the mounted grip is released.

  Next, a grip that can be selectively attached to the imaging apparatus main body will be described in detail.

  First, the structure of the grip will be described. FIG. 13 is a diagram illustrating the small grip 40. FIGS. 13A and 13B show views of the small grip 40 viewed from the back side and the side surface, respectively. FIG. 14 is a diagram illustrating the large grip 50. FIGS. 14A and 14B are views of the large grip 50 as viewed from the back side and the side surface, respectively. The small grip 40 or the large grip 50 functions as a grip member.

  The small grip 40 includes an external appearance part 400, a groove part 401 formed on the upper and lower ends, a concave shape 403 formed on one side surface of the center, and a protrusion part 402 formed protruding from the bottom surface. .

  The large grip 50 includes a grip portion 51 made of a resin material having a high friction coefficient, a metal plate 52, and a screw 53 that fixes the grip portion 51 and the metal plate 52.

  At the upper and lower ends of the large grip 50, a groove portion 501 formed by the metal plate 52 and the grip portion 51 is provided. Further, a concave shape 503 of the grip portion 51 and a protruding portion 521 formed on the metal plate 52 are provided on one side surface at the center of the large grip 50. Further, the metal plate 52 is formed with a protruding portion 523 in a half cut.

  When grips having different sizes can be selectively attached to the imaging apparatus main body, the manner in which a static pressure load is applied to the grip in the peeling direction differs depending on the size of the attached grip. Therefore, in this embodiment, the structures of the groove portions 401 and 501 are varied depending on the size of the grip. In the small grip 40 that requires only a small static pressure load, the cost is reduced by integrally forming the groove 401. In the large grip 50, the groove portion 501 is formed by two parts of the grip portion 51 and the metal plate 52 in order to withstand a large static pressure load.

  For example, in the state shown in FIG. 2B, even when a load in the peeling direction is applied to the large grip 50, the large grip 50 can receive a static pressure load on the metal plate 52.

  Further, when grips having different sizes can be selectively attached to the imaging apparatus main body, the amount of play at the tip of the attached grip varies depending on the size of the grip. For this reason, in this embodiment, only the large grip 50 is provided with a backlash removing mechanism by the protruding portion 521.

  Further, the large grip 50 is configured by combining a plurality of materials of the grip portion 51 and the metal plate 52. For example, when the grip portion 51 is formed of a material having high elasticity such as an elastomer and the large grip 50 is attached to the image pickup device main body 10, the grip portion 51 is elastically deformed and closely contacts the exterior cover of the image pickup device main body 10. Let As a result, the amount of play of the grip to be attached can be reduced.

  Next, an operation when the grip is attached to the imaging apparatus main body 10 will be described. FIG. 15 is a perspective view illustrating a state in which the small grip 40 is attached to the imaging apparatus main body 10. FIG. 16 is a perspective view for explaining how the small grip 40 is mounted on the grip mounting unit 60. The grip mounting unit 60 shown in FIGS. 15 and 16 is in an open state.

  The small grip 40 is attached to the imaging apparatus main body 10 in the present embodiment by inserting the small grip 40 into the opening 6010 as shown in FIGS. That is, by inserting the small grip 40 into the opening 6010 of the base member, the protruding portion 402 formed on the bottom surface of the small grip 40 abuts on the surface portion 6055 of the leaf spring 605 exposed from the opening 6010. Accordingly, the surface portion 6055 of the leaf spring 605 is pushed in the direction of the arrow in FIG. 16, and the engagement between the edge of the notch portion 6051 of the leaf spring 605 and the engagement protrusion 6025 of the first lock lever 602 is released. . When the first lock lever 602 is moved by the restoring force of the coil spring 604, when the engagement between the first lock lever 602 and the leaf spring 605 is released, the first lock lever 602 is moved by the restoring force of the coil spring 604. The lever 602 moves and the grip mounting unit 60 is closed. When the grip mounting unit 60 is closed, the lock portions 6021 and 6033 of the grip mounting unit 60 are engaged with the groove portions 401 formed at the upper and lower ends of the small grip 40, respectively. This completes the mounting of the small grip 40 to the imaging device main body 10.

  At this time, when the small grip 40 is inserted into the opening 6010 in an unintended insertion state (for example, tilted upward), only one side of the lock portions 6021 and 6033 is provided at the upper and lower ends of the small grip 40. May engage with the groove 401. Therefore, in the present embodiment, as shown in FIG. 12, the arm portion 6026 of the first lock lever 602 is a surface portion of the leaf spring 605 so that the area of the surface portion 6055 of the leaf spring 605 exposed from the opening 6010 is reduced. It is arranged so as to overlap with 6055. That is, when the small grip 40 is inserted obliquely, the protrusion 402 of the small grip 40 cannot push the surface portion 6055 of the leaf spring 605, so that the grip mounting unit 60 is not closed.

  Moreover, when it is inserted in the opposite direction depending on the shape of the grip, there is a concern that sufficient grip performance cannot be exhibited. In the present embodiment, a concave shape (regulating portion) 403 is provided on only one side of the small grip 40. Therefore, when the small grip 40 is inserted in the opposite direction, the protruding portion 402 is obstructed by the arm portion 6026 of the first lock lever 602 and the surface portion 6055 of the leaf spring 605 cannot be pushed in. The mounting unit 60 is never closed.

  The above-described structure is the same for the large grip 50.

  In the present embodiment, a backlash removing mechanism is provided only on the large grip 50. As shown in FIG. 14, the large grip 50 is formed with a protruding portion 521. Further, as shown in FIG. 12, an inclined portion 6026 a is formed at the tip of the arm portion 6026. The inclined portion 6026a is formed by bending the tip of the arm portion 6026 to the opening 6010 side. In the present embodiment, when attaching the large grip 50, the inclined portion 6026a formed at the tip of the arm portion 6026 of the first lock lever 602 before the upper and lower lock portions 6021 and 6033 engage with the groove portion 501. Enters the back side of the protruding portion 521 of the large grip 50. As a result, the large grip 50 is pulled in more strongly in the direction toward the imaging apparatus main body 10, that is, in the grip mounting direction that is the rear side direction in FIG. As a result, it is possible to reduce the play that occurs when the large grip 50 is attached to the imaging apparatus main body 10.

  Next, the grip removal operation will be described. FIG. 17 is a perspective view illustrating the grip removal operation.

  In the grip removal operation in the present embodiment, first, the lid 701 is opened, and the battery storage portion 705 is exposed as shown in FIG. The battery storage portion 705 is provided with a battery locking claw 7052. The battery locking claw 7052 can be moved between a battery locking state in which the battery 702 is locked and a non-locking state in which the battery 702 is not locked by a user operation.

  Next, as shown in FIG. 17B, the battery locking claw 7052 is brought into the non-locking state and the battery 702 is removed by the user's operation, so that the state shown in FIG.

  In the state of FIG. 17C, the operation unit 6020 of the first lock lever 602 is exposed. In the state shown in FIG. 17C, the user can push the operation unit 6020 to remove the grip.

  Here, the operation unit 6020 formed in the grip mounting unit 60 is disposed at a position where the user cannot operate in a state where the battery 502 is inserted. That is, in the state where the battery 502 is inserted, the operation unit 6020 is disposed at a position lower than the upper end of the battery 502. Thereby, in a state where the battery 502 is inserted in the battery storage unit 705, there is no possibility that the user unintentionally touches the operation unit 6020, so that the grip is not easily removed.

  FIG. 18 is a bottom view of the imaging apparatus main body 10 when the grip is removed. 18A shows a state in which the 10 small grip 40 is attached to the image pickup apparatus body, and FIG. 18B shows a state in which the operation unit 6020 is operated from FIG. 18A.

  As shown in FIG. 18A, the grip 40 is set so that the amount of protrusion from the surface of the imaging device body 10 is extremely small. In addition, the grip mounting unit 60 moves in a direction in which the leaf spring 605 pushes out the grip 40 by the detaching operation that shifts from FIG. 11B to FIG. As a result, as shown in FIG. 18B, the grip 40 is lifted so as to jump out from the surface of the image pickup apparatus body 10. It can be easily removed from the main body 10. That is, when the grip is removed, the grip is lifted from the surface by the height of the engagement protrusion 6025 provided on the lock portion 6021, so that even the small grip 40 can be gripped by the user.

  As described above, in the grip mounting mechanism of the present embodiment, the leaf spring 605 is engaged with the engagement protrusion 6025 provided on the lock portion 6021 by being displaced in the grip discharge direction. Accordingly, the lock portion 6021 of the first lock lever 602 and the lock portion 6033 of the second lock lever 603 are locked in the opened state retracted from the opening 6010 of the grip mounting unit 60 (see FIG. 12). By inserting the grip into the opening 6010 of the grip mounting unit 60, the leaf spring 605 and the engagement protrusion 6025 are disengaged, and the grip is fixed to the imaging apparatus main body 10. When the grip is discharged, the leaf spring 605 is displaced in the grip discharge direction, so that the grip can be pushed out to the surface side. Accordingly, it is possible to provide a grip having a small convex amount or a grip cap configured on the same surface as the camera appearance surface.

  In addition, the camera of the present embodiment can be equipped with a grip with only one action of inserting the grip into the opening. When removing, the grip can be removed by a two-action operation of opening the lid 701 and pushing in the operation unit 6020 so that the user does not intend to remove it.

  As described above, in the present embodiment, it is possible to selectively attach and detach a grip having an optimum size according to the lens with the same amount of effort as the replacement of the lens. This makes it possible to select and attach a large grip when using a large lens and a small grip when using a small lens. In other words, it is possible to provide a small imaging device having an optimum gripping performance.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
