  As described above, the imaging device 1 that is a waterproof device according to an embodiment of the present invention has a waterproof function for enabling use in water, and is provided with a rotary operation type operation member (rotation operation lever). ; See the reference numeral 4 in the drawing).

  The operation unit 20 in the imaging apparatus 1 according to the present embodiment is a set including a plurality of operation members including a rotation operation lever (symbol 4) and a pressing operation type operation member (symbols 5 and 6). It is a solid. As shown in FIG. 1, the operation unit 20 is disposed on the left side of the upper surface of the imaging device 1.

  The imaging apparatus 1 according to the present embodiment covers a main body housing 2 serving as a basic housing, a plurality of constituent units (not shown) housed in the main body housing 2, and an outer surface of the main body housing 2. A plurality of exterior members (for example, the top cover 3 and other exterior members are not shown), and a plurality of operation members (reference numerals 4, 5, 6, etc.) disposed so as to be partially exposed from the outer surface of the exterior member. ) And the like.

  The main body housing 2 is formed in a shape that substantially covers each surface (front surface, top surface, bottom surface, left and right side surfaces) other than the back surface of the imaging device 1 and has a space inside, for example, a substantially rectangular box shape. Yes. Various constituent units (not shown) are accommodated in the main body housing 2.

  On the front surface of the main body housing 2, an imaging opening 2a is formed at a substantially central portion (see FIG. 1). The imaging aperture 2 a is an aperture for introducing a light beam from the subject into the imaging device 1. Further, on the upper surface of the main body housing 2, an operation unit unit disposition opening 2 b for disposing the operation unit unit 20 is formed on the left side thereof. Each of the constituent members constituting the operation unit 20 is partially outside the main body housing 2 with the operation unit unit opening 2b (the upper surface of the main body housing 2 forming the operation unit) interposed therebetween. The other part is disposed inside the main body housing 2. In short, among the constituent members included in the operation unit 20, a plurality of operation members (4, 5, 6) and the like are disposed outside the main body housing 2, and the plurality of operation members A plurality of electrical components (a plurality of electrical switches (symbols 10a, 10b, 10c) and an electrical board (symbol 10) on which these are mounted; all of which will be described in detail later), etc.) Is disposed inside.

  Next, a detailed configuration of the operation unit 20 will be described. That is, the operation unit 20 includes a plurality of operation members (reference numerals 4, 5, and 6), a zoom base member 7, a top frame plate 8, an electric board 10, a base frame plate 11, and a zoom pusher ( plunger) 12, zoom spring 13, release spring 14, etc., top cover 3 that is a part of the exterior member, and waterproof rubber 9 that is a waterproof means and a watertight cover member.

  The top cover 3 is an exterior member that covers a part of the outer surface of the main body housing 2, that is, a portion on the left side of the upper surface. The top cover 3 is fixed to the upper surface of the main body housing 2 using a plurality of screws 15. In the present embodiment, as shown in FIG. 1, an example in which two screws 15 are used as fixing screws for the top cover 3 is shown.

  In addition, as described above, the top cover 3 is an exterior member that covers a part of the outer surface of the imaging device 1, but each of the plurality of operation members (reference numerals 4, 5, and 6) can be operated from the outside. Therefore, a part of each operation member is configured to be exposed to the outside. That is, the top cover 3 is configured to expose a part of the plurality of operation members (reference numerals 4, 5 and 6) and to cover the other parts. Further, the top cover 3 is also a holding member that holds the rotation operation lever (reference numeral 4) of the plurality of operation members (reference numerals 4, 5, and 6) in a state where the rotation operation can be performed.

  Of the plurality of operation members (reference numerals 4, 5, 6), a rotation operation lever (reference numeral 4) is an operation member (zoom lever 4) for performing a zooming operation, for example. Of the plurality of operation members (reference numerals 4, 5, and 6), a pressing operation type operation member indicated by reference numeral 5 is, for example, a release operation member (shutter release button 5) for performing a shutter release operation. Of the plurality of operation members (reference numerals 4, 5, 6), a pressing operation type operation member indicated by reference numeral 6 is, for example, a power operation member (power button for performing an on / off operation of the power of the imaging device 1. 6).

  The zoom lever 4 is configured to surround the outer peripheral edge of the shutter release button 5. The zoom lever 4 is attached to the top cover 3 by, for example, a bayonet type coupling means. In this case, the zoom lever 4 has a rotation axis X1 (see FIG. 1) which is a central axis (pressing shaft 5a; described later) of the shutter release button 5 and a rotation central axis coaxial with the movement axis. It is attached to the top cover 3 so as to be reciprocally rotatable in both forward and reverse directions around the rotation axis X1.

  That is, in detail, the zoom lever 4 (rotating operation type operation member; rotating operation lever) includes an operation unit 4a and a plurality of engagement arm units 4b as shown in FIGS. And a pressing protrusion 4c and a through hole 4d. The operation unit 4a is a finger hook unit that is used by a user (user) to turn and operate the zoom lever 4 around the rotation axis X1 (in the direction of arrow R in FIG. 1). It is.

  The plurality of engaging arm portions 4 b are components for securing the bayonet coupling between the zoom lever 4 and the top cover 3. Therefore, the plurality of engaging arm portions 4b are in a direction parallel to the rotation axis X1, that is, in a state in which the zoom lever 4 is attached to the top cover 3 so as to face from the top surface to the bottom surface (downward direction). Projected to A plurality of engaging arm portions 4 b are arranged so as to be substantially equidistant in the circumferential direction of the zoom lever 4. In the present embodiment, an example in which three engagement arm portions 4b are provided is shown. Therefore, in this embodiment, these three engagement arm parts 4b shall be arrange | positioned at intervals of the angle of about 120 degree | times in the circumferential direction.

  In this case, each end of each of the plurality of engaging arm portions 4b is provided with an engaging claw. The engaging claws of the plurality of engaging arm portions 4b are engaged with an engaged portion (not shown) of the top cover 3 to prevent removal in the axial direction.

  With such a configuration, the zoom lever 4 is bayonet-engaged with the top cover 3 and is allowed to rotate about the rotation axis X1 (in the direction of arrow R). The movement of the dynamic axis X1 in the axial direction is restricted and is prevented from falling off. The rotation restriction around the rotation axis X1 of the zoom lever 4 (in the direction of arrow R in FIG. 1) is restricted within a certain angle to prevent the bayonet from being disengaged. One of the engaging arm portions 4b is arranged between a pair of wall portions 7f (see FIG. 1; FIG. 3 not shown) of an arc-shaped recess formed in the zoom base member 7. Since this type of bayonet coupling is a well-known technique, the illustration and description of the further detailed configuration is omitted.

  The zoom lever 4 is restricted in its rotation range so as to reciprocate within a predetermined range. Since the structure for restricting the rotation range in this case is well known, it will not be described in detail. In short, for example, by providing a rotation prevention member that prevents movement of each of the engaging arms 4b or the operating portion 4a of the zoom lever 4 or one of the circumferential directions at a predetermined position, the zoom lever 4 is provided. The configuration for restricting the rotation range of 4 within a predetermined range can be easily realized.

  A zoom spring 13 that is an urging spring for holding the neutral position of the zoom lever 4 is provided on the rotation axis X1 of the zoom lever 4. The zoom spring 13 is formed by a torsion spring, for example. The zoom spring 13 is wound around the rotation axis X1 of the zoom lever 4, specifically, around the pressing shaft 5a of the shutter release button 5, and the end arm 13a of the zoom spring 13 is connected to the zoom spring 13. It is engaged so as to sandwich any one of the plurality of engaging arm portions 4b. With such a configuration, the zoom lever 4 is held at the neutral position in the rotation direction around the rotation axis X1 (arrow R).

  That is, when the zoom lever 4 is in the neutral position, the user (user) rotates the zoom lever 4 in one direction or the other in the reciprocating rotation direction around the rotation axis X1 (arrow R). Then, the zoom lever 4 rotates against the urging force of the zoom spring 13, and the engaging arm portion 4b also rotates in the same direction around the rotation axis X1 (arrow R). Thus, the zoom spring 13 is stored. When the user (user) releases the rotation operation at any time, the zoom lever 4 is moved in a rotation direction opposite to the rotation operation direction by the urging force stored in the zoom spring 13. It is configured to rotate and return to the neutral position.

  The pressing protrusion 4c is a component that protrudes toward the tip in any one of the plurality of engaging arm portions 4b. The pressing protrusion 4c protrudes in an arc shape parallel to the rotation axis X1 and along the circumferential direction, and is accompanied by reciprocal rotation around the rotation axis X1 of the zoom lever 4 (arrow R). It is formed to be movable in the circumferential direction around the rotation axis X1.

  Furthermore, the through hole 4d is a through hole centered on the rotation axis X1. A shutter release button 5 is disposed in the through hole 4d so as to be movable in a direction along the rotation axis X1. That is, the zoom lever 4 is configured to surround the outer peripheral edge of the shutter release button 5 in a state where the shutter release button 5 is disposed in the through hole 4d.

  The shutter release button 5 is a pressing operation type operation member having a pressing shaft 5a and a plurality of rotation stopping arm portions 5b. As shown in FIG. 1, the pressing shaft 5 a is a rod-shaped portion that acts on the shutter switch 10 b among a plurality of switch members mounted on an electric board 10 (details will be described later) provided inside the imaging apparatus 1. The pressing shaft 5a is disposed so as to substantially coincide with the rotation axis X1 of the zoom lever 4.

  As shown in FIGS. 1 and 6, the plurality of rotation stopping arm portions 5 b are arranged in parallel to the rotation axis X 1 from the outer peripheral edge portion of the shutter release button 5 (the shutter release button 5 is attached to the top cover 3. It is a component part which protrudes in the direction (downward) which faces a bottom face from an upper surface in a state (refer FIG. 6). The plurality of rotation stop arm portions 5 b are arranged at substantially equal intervals along the outer periphery of the shutter release button 5. In the present embodiment, an example in which three of the plurality of rotation stop arm portions 5b are formed is shown. Therefore, in this embodiment, these three rotation stop arm parts 5b shall be arrange | positioned at intervals of about 120 degree | times in the circumferential direction.

  On the other hand, the zoom cover 4 is rotatably disposed on the top cover 3 so as to correspond to the zoom lever 4 and the shutter release button 5, and the shutter release button 5 is arranged along the rotation axis X1. A through hole 3a is formed so as to be freely pressed. The through hole 3a is a substantially circular through hole having the rotation axis X1 as a central axis. The engaged portion (not shown) is formed on the inner peripheral edge of the through hole 3a. Thereby, the top cover 3 functions as a holding member that exposes the zoom lever 4 to the outside and holds the zoom lever 4 rotatably.

  At the same time, the shutter release button 5 is disposed in the through hole 4d of the zoom lever 4 so as to be freely pressed in the direction along the rotation axis X1. Accordingly, the top cover 3 is also a member that exposes a part of the shutter release button 5 to the outside and arranges the shutter release button 5 so as to be freely pressed in the direction of the rotation axis X1.

  Further, the top cover 3 is formed with a through hole 3b at a portion adjacent to the through hole 3a. The through hole 3b has a function of exposing a part of the power button 6 to the outside and holding the power button 6 in a direction parallel to the rotation axis X1. The power button 6 is a rod-shaped portion that acts on the power switch 10c among a plurality of switch members mounted on an electric board 10 (details will be described later) provided inside the imaging apparatus 1. The pressing shaft 6a is formed so as to extend downward (toward the bottom surface) in a direction parallel to the rotation axis X1 of the zoom lever 4.

  Next, a zoom base member 7, a top frame plate 8, and a waterproof rubber 9 are stacked in this order from the outer surface (upward) portion between the top cover 3 and the upper surface of the main body housing 2. It is arranged in a form.

  As shown in FIGS. 1 and 3 (or FIG. 6; however, the zoom pusher 12 is not shown in FIG. 6), the zoom base member 7 can swing the zoom pusher 12 (described later in detail; see FIG. 4). In addition to being disposed, the shutter release button 5 is disposed so as to be able to be pressed in a direction along the rotation axis X1, and the rotation of the shutter release button 5 around the rotation axis X1 is restricted. For this purpose, as shown in FIG. 3, the zoom base member 7 includes a zoom pusher arrangement portion 7a, a plurality of shutter button rotation restricting portions 7b, a shutter button shaft through hole 7c, and a release button engaged portion 7d. And an oscillation shaft fitting portion 7e.

  The plurality of shutter button rotation restricting portions 7b are interlocked with the zoom lever 4 when the shutter release button 5 (the state shown in FIG. 6) incorporated in the zoom base member 7 is rotated. This is a component that regulates rotation in the same direction. Therefore, when the shutter release button 5 is attached to the zoom base member 7, the shutter button rotation restricting portion 7 b is located at a position facing each of the plurality of rotation stop arm portions 5 b of the shutter release button 5. The same number as the rotation stop arm portion 5b is formed. The shutter button rotation restricting portion 7b is a pair of block members formed so as to sandwich the plurality of rotation stopping arm portions 5b in the circumferential direction.

  Furthermore, an engagement claw portion (not shown) is formed at the tip of the plurality of rotation stop arm portions 5b. The engaging claw portions at the tips of the respective rotation stop arm portions 5 b are engaged with release button engaged portions 7 d (see FIG. 3) formed on the zoom base member 7. Thus, when the shutter release button 5 is attached to the zoom base member 7, the engagement claw portions at the tips of the plurality of rotation stop arm portions 5b are engaged with the release button engaged portion 7d. The shutter release button 5 is configured not to fall out in a direction along the rotation axis X1. Further, it is not always necessary to prevent the shutter release button 5 from falling off by the engaging claw, and the zoom lever 4 is fitted to the outer periphery of the shutter release button 5 and only presses the step 5c of the shutter release button 5 from above. It is good also as a design.

  The shutter button shaft through-hole 7 c is a through-hole through which the pressing shaft 5 a of the shutter release button 5 incorporated in the zoom base member 7 is inserted. As a result, the pressing shaft 5 a of the shutter release button 5 passes through the through hole 3 a of the top cover 3 and then passes through the shutter button shaft through hole 7 c of the zoom base member 7. Furthermore, the pressing shaft 5a of the shutter release button 5 passes through a through hole 8b of a later-described top frame plate 8, and is fitted to a shaft fitting portion 9b of a later-described waterproof rubber 9.

  When the shutter release button 5 is attached to the zoom base member 7, a release spring 14 (see FIG. 1) is compressed between the zoom base member 7 and the shutter release button 5. Has been. The release spring 14 is constituted by, for example, a coil spring.

  With such a configuration, the shutter release button 5 is always urged away from the zoom base member 7 by the urging force of the release spring 14. In other words, the shutter release button 5 is always urged in the direction of being pushed up from the zoom base member 7 by the urging force of the release spring 14. However, at this time, in the shutter release button 5, as described above, the engaging claw at the tip of each rotation stop arm portion 5 b is engaged with the engaged portion (not shown) of the zoom base member 7. Accordingly, the shutter release button 5 is directed downward in the direction along the rotation axis X1 (toward the bottom surface) so that the shutter release button 5 does not come out of the zoom base member 7 by the urging force of the release spring 14 in the normal state. When the amount of pressing force is applied against the urging force of the release spring 14, it is held against the zoom base member 7 so as to be movable in the pressing direction.

  The zoom pusher arrangement portion 7a is a part in which the zoom pusher 12 (see FIG. 4) is disposed so as to be swingable in the arrow S direction. Here, the zoom pusher 12 is attached to the zoom base member 7 and is swung in the direction of arrow S in FIG. These are swing arm members that act on a pair of switch patterns (reference numeral 10a; see FIG. 1) on an electric substrate 10 (details will be described later). That is, the zoom pusher 12 is a structural member that converts the rotation operation of the zoom lever 4 (rotation operation lever) into a pressing operation.

  As shown in FIG. 4, the zoom pusher 12 is formed to have a swing shaft 12a, a pair of protruding arms 12b, and a pair of pressing portions 12c. The rocking shaft 12a is a rotating shaft portion having an axis (see symbol Ax shown in FIGS. 3 and 4) located on a surface intersecting with the rotating shaft X1 of the zoom lever 4 (rotating operation lever). . In the present embodiment, the axis is disposed orthogonal to the rotation axis X1. The swing shaft 12 a is rotatable with respect to the swing shaft fitting portion 7 e of the zoom base member 7 when the zoom presser 12 is disposed in the zoom presser placement portion 7 a of the zoom base member 7. It is arranged by fitting. With such a configuration, the zoom pusher 12 reciprocally swings in the direction of arrow S in FIG. 4 with the swing shaft 12a (rotation shaft portion) as a swing center.

  The pair of projecting arm 12b protrudes in both directions orthogonal to the swinging shaft 12a at a middle portion of the swinging shaft 12a (rotating shaft), and sandwiches the swinging shaft 12a. It is a pair of component parts arranged on both sides. In other words, the pair of components can be said to be projecting arms that are arms extending in the radial direction from the swing shaft 12a. Each of the pair of projecting arms 12b is formed with an inclined surface that is an obtuse angle with respect to the swing shaft 12a and that is a plane including the swing shaft 12a and is relatively inclined. Both inclined surfaces are formed to be continuous surfaces connected by a smooth curved surface passing through the vicinity of the outer peripheral surface of the swing shaft 12a. Briefly speaking, the pair of projecting arms 12b are formed in a V-shaped cross section on a plane orthogonal to the swing shaft 12a, and the swing shaft 12a is formed in the V-shaped valley portion. It is a form to be disposed. When the zoom pusher 12 is attached to a predetermined position of the zoom base member 7, the pair of projecting arm 12b is in the direction of the arrow S with the pivot shaft 12a as the center of rotation in the zoom pusher arrangement portion 7a. Is arranged so as to generate a swinging motion.

  In this way, when the zoom lever 4 is assembled to the zoom base member 7 to which the zoom pusher 12 is attached, the pressing projection 4c of the zoom lever 4 is the pair of projection arms. It arrange | positions in the position facing 12b.

  With such a configuration, when the zoom lever 4 is in the neutral position, the pressing projection 4c is between the pair of inclined surfaces and does not act on the pair of inclined surfaces. When the zoom lever 4 is turned from the neutral position, the pressing projection 4c of the zoom lever 4 moves in a direction substantially orthogonal to the swing shaft 12a along the pair of projection arms 12b. To do. Thereby, the pressing protrusion 4c of the zoom lever 4 abuts on one inclined surface of the pair of protruding arms 12b and presses the inclined surface. Accordingly, the protruding arm 12b swings in one direction along the arrow S with the swinging shaft 12a as the center of rotation.

  That is, when the zoom lever 4 (rotation operation lever) rotates in one direction, one protruding arm 12b of the pair of protruding arms 12b is pressed and displaced. When the zoom lever 4 (rotation operation lever) rotates in the other direction, the other protruding arm 12b of the pair of protruding arms 12b is pressed and displaced.

  In addition, the press part 12c is provided in each site | part of the back surface side of each inclined surface of said pair of protrusion arm 12b, respectively. The pair of pressing portions 12c are configured so that when the zoom lever 4 is rotated and the zoom pusher 12 swings about the swinging shaft 12a, a predetermined portion of the waterproof rubber 9 (described later in detail) ( This is the part that presses the pressed part 9a).

  A plate-like top frame plate 8 made of a highly rigid material is disposed below the zoom base member 7 (on the bottom side). The top frame plate 8 is sandwiched between the lower surface (the surface facing the bottom surface) of the zoom base member 7 and the upper surface of the waterproof rubber 9. As a result, the top frame plate 8 mounts and supports the zoom base member 7 on the top surface thereof, and the bottom surface (surface opposite to the bottom surface) is in close contact with the waterproof rubber 9, thereby opening the waterproof frame 9. The waterproof function around 2b is realized.

  For this purpose, the top frame plate 8 is formed of, for example, a pressed metal flat plate member. The top frame plate 8 has a plurality of holes. For example, a through hole 8a in which the zoom pusher 12 is disposed and allowed to swing, a through hole 8b through which the pressing shaft 5a of the shutter release button 5 is inserted, a through hole 8c through which the pressing shaft 6a of the power button 6 is inserted, and the like. Is formed. Accordingly, the waterproof rubber 9 is disposed so as to be in close contact with the lower surface (the surface facing the bottom surface) of the top frame plate 8 in a region other than the plurality of holes.

  A waterproof rubber 9 is disposed on the lower side of the top frame plate 8 (the surface facing the bottom surface). In this case, the waterproof rubber 9 is disposed so as to close the operation unit unit opening 2 b on the upper surface of the main body housing 2. That is, the waterproof rubber 9 is a watertight cover member that is interposed between the operation unit unit 20 and the main body housing 2 and realizes a waterproof function therebetween.

  The waterproof rubber 9 is formed by an elastic member such as silicone rubber which is an elastomer as a whole, and the outer peripheral edge 9d is formed so as to coincide with the periphery of the operation unit unit opening 2b. Yes.

  As shown in FIG. 1, the waterproof rubber 9 has a pair of pressed portions 9a, a shaft fitting portion 9b having a bottomed hole, and a shaft fitting portion 9c having a bottomed hole. Has been. Corresponding to these, as shown in FIG. 5, the waterproof rubber 9 has a pair of contacts 9aa, a shutter projection 9bb, and a power projection 9cc on the bottom surface (the surface facing the bottom surface). Is formed.

  The pair of pressed portions 9a are portions having a pair of contact points 9aa on the corresponding lower surface (the surface facing the bottom surface). The pair of pressed portions 9a is a component that the zoom pusher 12 swings and is pressed in the same direction by one or the other of the pair of pressing portions 12c when the zoom lever 4 is rotated. . The pair of contacts 9aa are conductive chip portions that act on a pair of switch patterns 10a (details will be described later) on the electric board 10 to be described later. One of the pair of contacts 9aa is referred to as a first contact, and the other is referred to as a second contact. One of the pair of switch patterns is referred to as a first switch pattern, and the other is referred to as a second switch pattern.

  When the zoom pusher 12 (swinging arm member) is swung by the turning operation of the zoom lever 4 and one of the pair of projecting arms 12b is displaced, the first arm 12b is displaced. It is assumed that the first contact pattern 9aa of the electric board 10 electrically turns on the first switch pattern 10a. Similarly, when the other protruding arm 12b of the pair of protruding arms 12b is displaced, the second contact 9aa electrically turns on a second switch pattern 10a of the electric board 10 described later. Shall.

  The shaft fitting portion 9b is a portion where the tip of the pressing shaft 5a of the shutter release button 5 is fitted and fixed. A shutter convex portion 9bb is formed on the lower surface (surface facing the bottom surface) side of the shaft fitting portion 9b. That is, the shaft fitting portion 9b is a component that is pressed by the pressing shaft 5a when the shutter release button 5 is pressed. The shutter projection 9bb is disposed so as to face a shutter switch 10b on the electric board 10 to be described later. With this configuration, when the shaft fitting portion 9b is pressed, the shutter convex portion 9bb also moves downward (towards the bottom surface) and presses the shutter switch 10b.

  The shaft fitting portion 9c is a portion where the pressing shaft 6a of the power button 6 is fitted and arranged. On the back surface (lower surface) side of the shaft fitting portion 9c, a power projection 9cc is formed. That is, the shaft fitting portion 9c is a component that is pressed by the pressing shaft 6a when the power button 6 is pressed. The power projection 9cc is disposed so as to face a power switch 10c on the electric board 10 to be described later. With this configuration, when the shaft fitting portion 9c is pressed, the power projection 9cc also moves downward to press the power switch 10c. The periphery of the shaft fitting portions 9b and 9c formed on the plate portion formed in the plate shape of the waterproof rubber 9 is formed in a thin wall shape, and each of the shaft fitting portions 9b and 9c is easily formed on the plate portion. It can be displaced in the thickness direction. Further, the periphery of the pair of pressed portions 9a is also tapered and is similarly formed thin, and can be easily displaced in the thickness direction of the plate portion as described above.

  An electric substrate 10 and a base frame plate 11 are laminated and provided inside the operation unit unit opening 2 b of the main body housing 2 with the waterproof rubber 9 interposed therebetween.

  The electric board 10 has a first switch pattern and a second switch pattern (reference numeral 10a), and the first switch pattern 10a is disposed at a position facing the one projecting arm 12b. The pattern 10a is disposed at a position facing the other protruding arm 12b. In addition, electrical components such as a shutter switch 10b and a power switch 10c are mounted and disposed on the electrical board 10, for example.

  The base frame plate 11 is a structural member that mounts and supports the electric substrate 10. The base frame plate 11 is formed of, for example, a pressed metal flat plate member.

  In other words, it can be said that the waterproof rubber 9 is disposed between the zoom pusher 12 (swinging arm member) and the electric board 10. In this case, the waterproof rubber 9 covers the pair of (first and second) switch patterns (symbol 10a) of the electric board 10 in a watertight manner.

  The main configuration of the imaging apparatus 1 of the present embodiment is as described above. Since the configuration other than the above in the imaging apparatus 1 of the present embodiment is a portion not directly related to the present invention, detailed illustration and description thereof will be omitted.

  In the imaging apparatus 1 according to the embodiment configured as described above, the operation of the operation unit 20 will be briefly described below.

  In a state where the constituent members of the operation unit unit 20 shown in FIG. 1 are assembled to the main body housing 2 in the imaging apparatus 1, the user (user) holds the zoom lever 4 in a predetermined direction along the arrow R shown in FIG. It is assumed that the rotation operation is performed in the direction, for example, the direction of arrow R1 in FIG. At this time, the zoom lever 4 is rotated in the rotation operation direction against the urging force of the zoom spring 13. Thereby, the zoom spring 13 is stored.

  When the zoom lever 4 is rotated in the direction of the arrow R1 in FIG. 7 in response to the rotation operation, the pressing protrusion 4c of the zoom lever 4 is moved in the same direction. The movement of the pressing protrusion 4c at this time can be shown as a movement in the direction of the arrow H1 in FIG. 7, for example. Thus, when the pressing projection 4c moves in the direction of the arrow H1 in FIG. 7, the pressing projection 4c comes into contact with the inclined surface of one projection arm 12b of the zoom pusher 12, and this is the same direction ( Press in the direction of arrow H1. As a result, the zoom presser 12 swings in the direction of arrow S1 in FIG. Then, one pressing portion 12 c of the zoom pusher 12 presses one pressed portion 9 a of the waterproof rubber 9. As a result, the first contact 9aa of the waterproof rubber 9 contacts the first switch pattern 10a of the electric board 10 to turn it on electrically.

  When the rotation operation by the user (user) to the zoom lever 4 is released, the zoom lever 4 is rotated by the urging force stored in the zoom spring 13 (here, the direction of the arrow R1). It rotates in the opposite rotation direction (arrow R2 direction in FIG. 7). Then, the zoom lever 4 returns to a predetermined neutral position.

  On the other hand, when the zoom lever 4 is in the neutral position and the user (user) rotates the zoom lever 4 in the direction of the arrow R2 in FIG. Become. That is, when the zoom lever 4 rotates in the arrow R2 direction, the pressing protrusion 4c moves in the arrow H2 direction. As a result, the pressing projection 4c comes into contact with the inclined surface of the other projection arm 12b of the zoom pusher 12 and presses it in the direction of the arrow H2. As a result, the zoom pusher 12 swings in the direction of the arrow S2. Then, the other pressing portion 12 c of the zoom pusher 12 presses the other pressed portion 9 a of the waterproof rubber 9. As a result, the second contact 9aa of the waterproof rubber 9 comes into contact with the second switch pattern 10a of the electric board 10 and is electrically turned on.

  When the rotation operation by the user (user) on the zoom lever 4 is released, the zoom lever 4 is rotated by the urging force stored in the zoom spring 13 (here, the direction of the arrow R2). It rotates in the opposite rotation direction (arrow R1 direction). Then, the zoom lever 4 returns to a predetermined neutral position.

  As described above, according to the above-described embodiment, in the imaging device 1 that is a waterproof device having the zoom lever 4 (rotating operation type rotating operation lever), the zoom lever 4 (rotating operation lever) rotates. A zoom pusher 12 (a swing arm member) that converts an operation into a pressing action is provided, and at least a pair of switch patterns 10a (first switch pattern and second switch pattern) on the electric board 10 are water-tightly covered. By arranging the rubber 9 (watertight cover member) between the electric substrate 10 and the zoom pusher 12 (swinging arm member), it is possible to achieve a favorable operation with a simpler configuration and a rotary operation type operation member. A sufficient waterproof mechanism can be realized while maintaining the properties.

  In this case, the waterproof rubber 9 is further provided with a pair of contact points 9aa, and the pair of contact points 9aa corresponds to the pressed portion 9a that is pressed by the pressing operation converted by the rotation operation of the zoom lever 4. It is provided. When the pressed portion 9a of the waterproof rubber 9 is pressed in response to the turning operation of the zoom lever 4, one of the pair of contacts 9aa or the other contact 9aa is a pair of switch patterns 10a on the electric board 10. It is comprised so that it may be turned on electrically by contacting one or the other of these.

  In this embodiment, the shutter release button 5 is pressed against the shutter switch 10b through the waterproof rubber 9. Instead, the fitting portion hole diameter of the shaft fitting portion 9b is set to an interference fit size. Using the hole of the shaft fitting portion 9b of the waterproof rubber 9 as a through hole, the pressing shaft 5a of the shutter release button 5 is passed through the through hole of the shaft fitting portion 9c, and this hole and this shaft are brought into close contact with each other. The pressing shaft 5a may directly press the shutter switch 10b. At the same time, the hole of the shaft fitting portion 9c of the waterproof rubber 9 may be used as a through hole so that the pressing shaft 6a of the power button 6 is also watertight in the same manner as described above so that the power switch 10c can be pressed directly.

  Therefore, in the imaging device 1 that is a waterproof device having the zoom lever 4 (rotating operation type rotating operation lever), it is simpler to ensure improved operability while maintaining necessary waterproof performance. Can be realized.
