Description

  The present invention relates to an apparatus main body, a hinge mechanism that rotatably supports a rotation member with respect to the apparatus main body, and an imaging apparatus including the hinge mechanism.

  An imaging apparatus such as a digital camera is equipped with a monitor such as an LCD panel in the apparatus body, and an image captured in the imaging apparatus body can be confirmed on the spot. The monitor is generally incorporated in the back of the apparatus main body facing the photographer at the time of photographing. The photographer can take a picture while confirming the image captured in the apparatus main body with a viewfinder or a monitor according to the photographing situation, and can confirm the photographed image on the monitor.

  In recent years, a digital camera has been proposed in which the monitor is separated from the apparatus main body and is rotatably supported with respect to the apparatus main body. In this type of digital camera, one end of a support arm is rotatably attached to the back of the apparatus body, and a monitor is attached to the other end of the support arm. Thereby, even when the photographer takes a photographing posture that cannot face the back of the apparatus main body, visibility can be ensured by rotating the monitor.

Japanese Patent Laid-Open No. 08-098068

  By the way, in a digital camera in which the monitor is rotatably supported, the monitor and the apparatus main body are connected by a flexible substrate. The flexible substrate is led out from the back surface of the apparatus main body and supported by the support arm and introduced into the monitor. At this time, the flexible substrate is arranged to have flexibility in the rotation direction of the support arm, and is bent following the rotation operation of the monitor.

  Here, the flexible substrate is led out of the apparatus main body and connected to the monitor. When exposed to the outside, there is a risk of adhesion or damage of dust or water droplets. Therefore, it is necessary to shield the flexible substrate from the outside by providing a cover on the hinge portion to which the support arm is attached. At this time, if a single-plate blindfold plate is used as the shielding member, the flexible substrate is exposed from the lower surface side of the apparatus body, which is insufficient. In addition, the shielding member is attached to the support arm, and the shielding member that can rotate integrally with the support arm increases the size of the support arm and the shielding member and requires a wide rotation area. It leads to weight.

  Therefore, an object of the present invention is to provide a hinge mechanism that effectively shields the flexible substrate from the outside and suppresses an increase in size and weight, and an imaging apparatus using the hinge mechanism.

The adjustment dial 28 has an adjustment pin protruding toward the inside of the eye cup 16 engaged with the lens block 18 engaged with the eye cup 16 and rotated by the user, so that the lens block 18 Focus adjustment can be performed by moving the lens group in the optical axis direction. The eye cup 16 is attached by being screwed to the upper part of the back surface 2c of the camera body 2.

  Next, the hinge mechanism 3 that supports the liquid crystal monitor 4 will be described. As shown in FIG. 4, the hinge mechanism 3 includes a support frame 22 and a support member 23 that supports the liquid crystal monitor 4. The hinge mechanism 3 rotates the liquid crystal monitor 4 supported by the support member 23 when the support frame 22 is attached to the back surface 2c of the camera body 2 and the support member 23 is rotatably supported by the support frame 22. It is something to move. Further, the flexible mechanism 21 that connects the camera body 2 and the liquid crystal monitor 4 is inserted into the hinge mechanism 3 and led into the liquid crystal monitor 4.

  The support frame 22 has a rectangular frame-shaped frame main body 25 attached to the camera body 2, and an insertion hole 26 through which the lens block 18 of the finder block 15 is inserted is formed in the frame main body 25.

  The frame main body 25 is provided with a pair of mounting pieces 27, 27 to which one end of each of the support arms 24, 24 of the support member 23 that supports the liquid crystal monitor 4 is mounted on both the left and right sides of the insertion hole 26. As shown in FIG. 2, the attachment piece 27 protrudes from the back surface 2 c of the camera body 2, and a support hole 30 that supports the support arm 24 is formed at the tip. The support hole 30 is connected to the attachment hole 36 formed in the one end 24a of the support arm 24, and then the caulking shaft 39 is inserted and caulked, whereby the support arm 24 is rotatably connected. In addition, the mounting piece 27 is formed with a restricting convex portion 31 that restricts the rotation range of the support member 23 between the base end on the frame body 25 side and the distal end. The restricting convex portion 31 is pivoted toward the upper surface 2 b side of the camera body 2 of the liquid crystal monitor 4 supported by the support member 23 when the locking piece 37 formed on the one end 24 a of the support arm 24 is locked. Regulate the range.

  The attachment piece 27 is formed so that the base end side of the frame body 25 is wide in the height direction and gradually becomes narrower toward the tip. The attachment piece 27 is formed to be wide on the base end side, so that resistance to pressure from the left-right direction is improved.

  The support member 23 supported by the mounting piece 27 includes a pair of support arms 24 and 24 and a connecting plate portion 35 provided between the support arms 24 and 24, and the pair of support arms 24 and 24. And the connecting plate part 35 is integrally formed. The support arm 24 is formed with an attachment hole 36 rotatably connected to the attachment piece 27 at one end 24a and an engagement piece 37 to be engaged with the restricting convex portion 31, and at the other end 24b a support in the liquid crystal monitor 4. A shaft hole 38 connected to the base is formed. The support arm 24 is connected by a caulking shaft 39 after the attachment hole 36 is continuous with the support hole 30 of the attachment piece 27. Further, the support arm 24 is rotatably connected by the shaft hole 38 being continuous with the panel housing 60 of the liquid crystal monitor 4 and a support portion formed on the support base and being caulked by a caulking shaft.

  The hinge mechanism 3 includes a friction disk between the support hole 30 of the support arm 24 and the attachment hole 36 of the attachment piece 27 and between the shaft hole 38 of the support arm 24 and the support base of the liquid crystal monitor 4. Intervened and connected. Accordingly, the support arms 24 and 24 are held at an arbitrary rotation position with respect to the support frame 22, and the liquid crystal monitor 4 is held at an arbitrary rotation position with respect to the support arms 24 and 24.

  Thereby, as shown in FIG. 5A, the hinge mechanism 3 is moved from the basic posture in which the support member 23 lowers the long side of the support arm 24 downward and makes the liquid crystal monitor 4 contact the back surface 2c of the camera body 2. As shown in FIG. 5B, the support member 23 rotates the long side of the support arm 24 upward by about 90 ° to operate the liquid crystal monitor 4 to the rotation posture separated from the back surface 2 c of the camera body 2. can do. Further, as shown in FIGS. 5B and 5C, the hinge mechanism 3 has the liquid crystal monitor 4 in a range of about 180 ° with the caulking shaft inserted into the shaft hole 38 of the support arm 24 as a support shaft. Can be rotated. Therefore, the imaging apparatus 1 can face the photographer by rotating the liquid crystal monitor 4 even in a photographing posture that cannot face the liquid crystal monitor 4 in the basic posture, and can maintain visibility. .

  The pair of support arms 24, 24 is formed with a bent portion 24c in which one end 24a side is bent at a right angle. Thus, the support arm 24 has a short side on one end 24a side and a long side on the other end 24b side, and a connecting plate portion 35 is formed on the long side. The hinge mechanism 3 is provided with a bent portion 24 c in the support arm 24 so that the liquid crystal monitor 4 is stored immediately below the one end 24 a of the support arm 24 when the liquid crystal monitor 4 is stored on the back surface 2 c side of the camera body 2.

  A hinge cover 40 that prevents the flexible substrate 21 from being exposed to the outside in the long side region of the support arm 24 is attached to the connecting plate portion 35. The hinge cover 40 has a back cover 40a attached from the back surface 2c side of the camera body 2 and a front cover 40b attached from the liquid crystal monitor 4 side. The front and back covers 40a and 40b are abutted and coupled to the connecting plate portion 35. Thus, an insertion space for the flexible substrate 21 is formed, and the flexible substrate 21 is prevented from being exposed to the outside.

  In the hinge cover 40, an engagement support portion 43 that engages and supports the shielding member 50 of the flexible substrate 21 and engages one end of a torsion coil spring 53 described later is formed on the end surface of the support arm 24 on the one end 24 a side. . The shielding member 50 prevents the flexible substrate 21 from being exposed to the outside in the vicinity of the bent portion 24c of the support frame 22 as the support member 23 rotates, and can be rotated to one end side of the front cover 40b. Is engaged. The engagement support portion 43 is formed with a shaft support portion that supports a support shaft 44 that is inserted through the bearing portion of the shielding member 50, and rotatably supports one end side of the shielding member 50.

  Next, the shielding member 50 engaged with the hinge cover 40 will be described. The shielding member 50 shields the flexible substrate 21 from the outside between the eye cup 16 and the hinge cover 40 and is formed of a substantially rectangular cylindrical member. The shielding member 50 has a length that is slightly shorter than the length between the pair of support arms 24, 24 in the longitudinal direction, and the engagement support portion 43 of the hinge cover 40 and the eye cup 16 in the short direction perpendicular to the longitudinal direction. The opening 19 has a length longer than the distance from the edge 20 formed in the opening 19.

  The shielding member 50 is formed with a bearing portion through which the support shaft 44 supported by the engagement support portion 43 of the hinge cover 40 is inserted on the long side 51 on one side in the short side direction. It is supported movably. Further, the shielding member 50 has a long side 52 on the other side in the short side direction locked to an edge portion 20 formed in the opening 19 of the eye cup 16. Thus, in the hinge mechanism 3, as shown in FIGS. 6A to 6C, the eye cup 16, the shielding member 50, and the hinge cover 40 are connected. Then, when the support member 23 is rotated with respect to the support frame 22, the shielding member 50 is rotated integrally with the support member 23 on the long side 51 side engaged with the hinge cover 40, and the edge portion of the eye cup 16. The side of the long side 52 locked to 20 slides on the edge portion 20.

  The shielding member 50 has long sides 51 and 52 on both sides in the short direction, and the flexible substrate 21 can be inserted. Accordingly, as shown in FIG. 7A, the hinge mechanism 3 includes the opening 19 of the eye cup 16, the hollow portion of the shielding member, and the inside of the hinge cover 40. The flexible substrate 21 led out from the inside passes through the hollow portion of the shielding member 50 and the inside of the hinge cover 40 and reaches the liquid crystal monitor 4. Therefore, the imaging apparatus 1 does not expose the flexible substrate 21 from the back surface 2 c of the camera body 2 to the inside of the liquid crystal monitor 4, and can prevent adhesion or damage of dust or water droplets.

  In addition, the torsion coil spring 53 is engaged with the shielding member 50 at the end of the long side 51 on one side in the short side direction that is engaged and supported by the hinge cover 40. The torsion coil spring 53 always rotates and biases the shielding member 50 in one direction with the support shaft 44 pivotally supported by the engagement support portion 43 of the hinge cover 40 as a fulcrum, so that the opening 19 and the shielding member of the eye cup 16 are rotated. 50 to prevent a clearance from being generated.

  That is, as shown in FIG. 7B, the torsion coil spring 53 has an annular portion through which the support shaft 44 is inserted, one end abuts against the hollow interior of the shielding member 50, and the other end is a surface of the hinge cover 40. It is latched by the engagement support part 43 formed in the cover 40b. Accordingly, the torsion coil spring 53 is urged to rotate in the direction of arrow A in FIG. 7B in which the long side 52 side of the shielding member 50 is always brought into contact with the edge portion 20 formed in the opening 19 of the eyecup 16. is doing.

  Thus, the torsion coil spring 53 urges the shielding member 50 to rotate, so that the hinge mechanism 3 is shown in FIG. 8A from the state of FIG. 7A in which the support member 23 is rotated downward. 8B, the long side 52 side of the shielding member 50 is slidably contacted with the edge portion 20 of the opening 19 of the eye cup 16, as shown in FIG. 8B. As shown in FIG. 9A, when the support member 23 is rotated to a position of approximately 90 °, the long side 52 side of the shielding member 50 is located on the opening 19 of the eye cup 16 as shown in FIG. There is no sliding between the shielding member 50 and the opening 19 of the eye cup 16 due to sliding contact with the edge portion 20. Accordingly, the hinge mechanism 3 can reliably shield the flexible substrate 21 from being exposed from between the shielding member 50 and the opening 19 of the eye cup 16 in the entire process of the rotation operation of the support member 23. it can. Similarly, when the support member 23 is returned from the position shown in FIG. 9 to the position shown in FIG. 7, no clearance appears between the shielding member 50 and the opening 19 of the eye cup 16.

  Further, since the hinge mechanism 3 is provided with the bent portion 24 c on the support arm 24, the hinge cover 40 cannot be attached, and the vicinity of the bent portion 24 c is exposed to the outside as the support member 23 rotates. However, the flexible substrate 21 can be reliably shielded by disposing the shielding member 50 in the bent portion 24c.

  As shown in FIGS. 8 and 9, the camera body 2 is formed with a shielding plate 55 that protrudes from the opening 19 of the eye cup 16 on the back surface 2 c. The shielding plate 55 shields the flexible substrate 21 disposed between the support arms 24 and 24 of the support member 23 from below the camera body 2 when the liquid crystal monitor 4 is rotated to the upper surface 2 b side of the camera body 2. To do. The shielding plate 55 is formed so as to protrude between the support arms 24 and 24 by attaching the support frame 22 to the back surface 2 c of the camera body 2, and the flexible substrate 21 is arranged between the lower surface of the lens block 17 of the finder block 15. Established.

  Here, as shown in FIGS. 10A to 10C, in the hinge mechanism 3, the edge portion 20 of the opening portion 19 of the eye cup 16 with which the long side 52 of the shielding member 50 is in sliding contact is chamfered in a round shape. Therefore, smooth sliding of the shielding member 50 is possible. That is, the edge portion 20 is chamfered in the rotational direction of the shielding member 50 over the entire side where the long side 52 of the shielding member 50 contacts. Further, the shielding member 50 is reciprocated on the same track that is in sliding contact with the edge portion 20 in the entire rotation of the liquid crystal monitor 4 while the long side 52 is biased toward the edge portion 20 by the torsion coil spring 53. In the hinge mechanism 3, the edge portion 20 of the opening 19 of the eye cup 16 is chamfered in a rounded shape, so that the shielding member 50 is stably brought into the edge portion 20 during the entire rotation of the liquid crystal monitor 4. It is possible to prevent sliding noise and shading of the shielding member 50 by sliding.

  Next, the liquid crystal monitor 4 that is rotatably supported by the camera body 2 via the hinge mechanism 3 will be described. As shown in FIG. 11, the liquid crystal monitor 4 includes a panel housing 60 formed in a substantially rectangular shape, and a support connected to the liquid crystal module 61 and the support arms 24 and 24 of the hinge mechanism 3 in the panel housing 60. A base 62 is provided.

  The panel housing 60 is formed by butting and joining the front half 60a and the back half 60b. The front half 60a is formed with a rectangular window 65 that faces the liquid crystal module 61 outward. As shown in FIG. 12A, the back half 60b is formed with a rectangular recess 66 into which the support member 23 of the hinge mechanism 3 enters.

  The concave portion 66 is formed from the substantially central portion of the back half 60b to the upper edge side, and has a width sufficient to fit the support member 23 to which the hinge cover 40 is attached. Further, the recess 66 has a lower end 24b of the support arm 24 inserted therethrough to form a rotation support portion 67 that is rotatably supported. The rotation support part 67 is faced between a pair of slits 67a through which the other ends 24b of the pair of support arms 24 and 24 are inserted, and the pair of slits 67a and 67a, and is a flexible substrate led out from the hinge cover 40. And an insertion port 67b into which 21 is inserted.

  By providing such a recess 66, as shown in FIG. 12B, the panel housing 60 has the shaft hole 38 in the other end 24b of the support arms 24, 24 in the slits 67a, 67a of the rotation support portion 67. The flexible substrate 21 that is pivotally connected and inserted through the hinge cover 40 of the hinge mechanism 3 is inserted through the insertion port 67b and connected to the liquid crystal module 61 disposed inside the housing.

  When the panel housing 60 is rotated around the rotation support portion 67 supported by the support member 23, the hinge cover 40 attached to the support member 23 is fitted into the recess 66. Therefore, the panel housing 60 has the camera body 2 made thinner by fitting the hinge cover 40 of the hinge mechanism 3 into the recess 66 in the basic posture in which the liquid crystal monitor 4 contacts the back surface 2c of the camera body 2. In addition, the back half 60b can be brought into close contact with the back surface 2c of the camera body 2, and shakiness of the liquid crystal monitor 4 in the basic posture can be prevented.

  In the basic posture in which the liquid crystal monitor 4 is rotated toward the back surface 2 c of the camera body 2, the imaging device 1 is configured such that each end 24 a of the support arm 24, 24 of the hinge mechanism 3 is positioned immediately above the panel housing 60. The support frame 22 that supports the one ends 24 a of the support arms 24 and 24 is covered with the eye cup 16. That is, as described above, the hinge mechanism 3 is provided with the insertion holes 26 through which the lens block 18 of the finder block 15 is inserted and supported in the frame body 25 of the support frame 22, and the support arms 24, A pair of mounting pieces 27, 27 that support 24 are erected. In this way, the hinge mechanism 3 is provided with the support arms 24 and 24 of the support member 23 that supports the liquid crystal monitor 4 at substantially the same height as the finder block 15, so that the finder block 3 as shown in FIGS. 1 and 2. 15 and the hinge mechanism 3 have substantially the same height, and the liquid crystal monitor 4 can be disposed immediately below the finder block 15.

  Therefore, the imaging apparatus 1 can be made shorter and improve portability and designability compared to an imaging apparatus in which the finder block 15, the hinge mechanism 3, and the liquid crystal monitor 4 are arranged in parallel in the height direction. . Moreover, the large-sized liquid crystal monitor 4 can be mounted without increasing the height of the camera body 2, and visibility can be improved.

  Although the imaging apparatus to which the present invention is applied has been described above, the present invention can be applied not only to the imaging apparatus 1 including the electronic viewfinder 10 but also to an imaging apparatus including an optical viewfinder (OVF). . Further, the present invention can be applied not only to the imaging device 1 including the liquid crystal monitor 4 but also to an imaging device including any display monitor such as an organic EL display.

  The present invention can be applied not only to a digital camera and a silver salt camera, but also to a video camera in which a monitor is supported so as to be rotatable with respect to the apparatus main body. Further, the hinge mechanism to which the present invention is applied can be applied to a hinge part in any electronic device such as a mobile phone and a laptop PC.
