  Of the pair of rotating plates 32 and 33, the second rotating plate 33 is formed with a pair of restricting pieces 55 a and 55 b that come into contact with the stopper protrusion 41 of the fixed plate 31 described above. The pair of restricting pieces 55a and 55b are disposed at an angular position of approximately 90 ° with the support shaft 34 as the center, and the main plate facing the first rotating plate 32 is punched out of the second rotating plate 33. It is bent on the surface side. On the other hand, the first rotating plate 32 is formed with a pair of openings 56a and 56b for allowing the pair of restricting pieces 55a and 55b to pass therethrough.

  In the movable hinge mechanism 20, when the pair of rotary plates 32 and 33 rotate in one direction around the support shaft 34 with respect to the fixed plate 31, one restriction piece 55 a is formed at one end of the stopper projection 41. On the other hand, when the pair of rotating plates 32 and 33 rotate in the other direction around the support shaft 34 with respect to the fixed plate 31, the other regulating piece 55 b contacts the other end of the stopper projection 41. Will be. Thereby, the angle range in which the grip part 4 is rotated with respect to the main body part 2 is restricted to approximately 90 °.

  The rotating hinge mechanism 20 is a first friction mechanism for stably holding the grip portion 4 with respect to the main body portion 2 at an arbitrary angular position where the grip portion 4 is rotated with respect to the main body portion 2. 57 and a second friction mechanism 58 are provided.

  The first friction mechanism 57 generates a friction on the inner peripheral side between the fixed plate 31 and the first rotating plate 32, and therefore, a spring plate 59 and a pressure plate arranged with the support shaft 34 penetrating therethrough. 60 and a friction plate 61.

  In the spring plate 59, a through hole 59a having substantially the same diameter as the first shaft portion 34a of the support shaft 34 is formed at the center of the substantially disc-shaped sheet metal, and the cross-sectional shape in the thickness direction is substantially C-shaped. It is a so-called spring washer.

  The pressure plate 60 is made of a substantially disc-shaped sheet metal having substantially the same diameter as the spring plate 59, and a through hole 60 a having substantially the same diameter as the second shaft portion 34 b of the support shaft 34 is formed at the center thereof.

In addition, a positioning piece 60 b that serves as a rotation stopper for the pressure plate 60 is formed on the outer periphery of the pressure plate 60 so as to be bent at a right angle with respect to the main surface of the pressure plate 60. On the other hand, the fixing plate 31 is formed with a notch recess 62 formed so as to partially cut out the periphery of the shaft hole 36, and the pressure plate 60 has the through hole 60 a as the second shaft of the support shaft 34. When the positioning piece 60b is engaged with the notch recess 62 of the fixing plate 31 with the portion 34b penetrating, the spring plate 59 is positioned and fixed to the fixing plate 31 while being sandwiched between the fixing plate 31 and the positioning plate 60b. ing.

  The friction plate 61 is made of a substantially disc-shaped high friction member having substantially the same diameter as the pressure plate 60, and a through hole 61 a having substantially the same diameter as the second shaft portion 34 b of the support shaft 34 is formed at the center thereof. Is formed. The friction plate 61 is disposed in a state of being sandwiched between the rotating plate 32 and the pressure plate 60 with the second shaft portion 34b of the support shaft 34 passing through the through hole 61a.

  Therefore, in the first friction mechanism 57, the spring plate 59 compressed between the fixed plate 31 and the first rotating plate 32 presses the pressure plate 60, and the pressure plate 60 presses against the friction plate 61. As a result, moderate friction can be generated.

  The second friction mechanism 58, together with the ring portion 46 of the outer peripheral ring plate 45 described above, generates the friction on the outer peripheral side between the fixed plate 31 and the first rotating plate 32. The spring plate 63 is disposed in a compressed state between the outer peripheral portion of the rotary plate 32.

  The spring plate 63 is made of a substantially annular sheet metal having substantially the same diameter as the ring portion 46 of the outer peripheral ring plate 45, and has a shape that is bent in a wave shape in the thickness direction. In addition, at a position where the outer peripheral portion of the spring plate 63 is divided into approximately two equal parts in the circumferential direction, a pair of positioning pieces 64 that serve as a rotation stop for the spring plate 63 are perpendicular to the main surface of the spring plate 63. It is bent and formed. On the other hand, the fixed plate 31 is formed with a pair of positioning holes 65 into which the pair of positioning pieces 64 are engaged. The spring plate 63 is sandwiched between the fixed plate 31 and the outer peripheral portion of the first rotating plate 32, and the pair of positioning pieces 64 are engaged with the pair of positioning holes 65. It is positioned and fixed to the fixed plate 31.

  Therefore, in the second friction mechanism 58, the spring plate 63 compressed between the fixed plate 31 and the outer peripheral portion of the first rotating plate 32 presses the first rotating plate 32, and this first rotation. Appropriate friction can be generated by pressing the outer peripheral portion of the plate 32 against the ring portion 46 of the outer peripheral ring plate 45.

  As described above, in the rotating hinge mechanism 20, the body portion 2 and the grip portion 4 are rotatably supported, and the inner peripheral side between the fixed plate 31 and the first rotating plate 32 and By providing the first friction mechanism 57 and the second friction mechanism 58 for applying friction to the outer peripheral side, the grip portion 4 can be appropriately and stably held at an arbitrary angular position with respect to the main body portion 2. It is.

  Further, in the rotary hinge mechanism 20, even when the first friction mechanism 57 and the second friction mechanism 58 are provided, the main body portion 2 and the grip through the first opening 40 and the second opening 54 are provided. The harness 66 can be easily routed between the body 4 and the harness 66 that is routed between the main body 2 and the grip 4.

  Further, in the rotating hinge mechanism 20, even when a click mechanism that provides a click feeling at a predetermined position when the grip portion 4 is rotated is provided, the inner peripheral spring plate 59 and the outer peripheral spring plate are provided. It is possible to keep the friction constant without affecting the pressing by 63.

  Therefore, in the digital video camera 1 having such a rotating hinge mechanism 20, the entire apparatus is further reduced in size, and the grip portion 4 is appropriately and stably held at an arbitrary angular position with respect to the main body portion 2. Is possible.

  By the way, in the digital video camera 1 described above, as shown in FIG. 11, a harness 66 for electrically connecting the main body 2 side and the grip 4 side is a first opening of the rotary hinge mechanism 20. Through the part 40 and the second opening 54, it is routed between the inside of the housing on the main body 2 side and the inside of the housing on the grip 4 side.

  Here, as shown in FIGS. 12 and 13, the first opening 40 and the second opening 54 have an angle range in which the grip part 4 is rotated with respect to the main body part 2 (here, 90. In the angle range of 0 °, at least a part thereof is formed to overlap.

  In this case, the harness 66 routed between the main body 2 and the grip 4 is between the first opening 40 and the second opening 54 that overlap each other (hereinafter referred to as the overlap portion 67). The harness 66 can be bent gently, and the harness 66 can be easily routed through the overlap portion 67.

  Specifically, as shown in FIG. 14, the harness 66 is a long flexible printed wiring board (hereinafter referred to as an FPC 66) formed with a predetermined width, and follows the rotational movement of the grip portion 4. In order to be able to do so, a curved portion 66a curved in the main surface is provided in the intermediate portion. As shown in FIG. 15, the curved portion 66 a is a portion that is folded back between the first opening 40 and the second opening 54 that overlap each other, and is a first opening that is centered on the support shaft 34. 40 and the second opening 54 have substantially the same radius of curvature.

  As shown in FIGS. 11, 12 and 13, the FPC 66 has a curved portion 66 a that is substantially U-shaped through an overlap portion 67 between the first opening 40 and the second opening 54. The one end side is drawn to the main body part 2 side through the second opening 54 and the other end side is drawn to the grip part 4 side through the first opening 40.

  Here, the FPC 66 folded back in the overlap portion 67 follows the rotational movement of the pair of rotating plates 32 and 33 with respect to the fixed plate 31 and displaces the folding position of the bending portion 66 a in the overlap portion 67. It will be.

At this time, the angle at which the folding position of the FPC 66 shown in FIG. 15 is displaced is β / 2 with respect to the angle β at which the pair of rotary plates 32 and 33 shown in FIG. 11 is rotated with respect to the fixed plate 31. Therefore, in order to form the overlap portion 67 between the first opening 40 and the second opening 54, at least the angular range of the first opening 40 and the second opening 54 is set to the grip portion. 4 needs to be more than half of the maximum angle (β _m ) rotated with respect to the main body 2.

Specifically, as shown in FIG. 12, the angle range of the first opening 40 is set so that the grip portion 4 has a main body portion so that the connector 68 attached to the FPC 66 can be easily passed after the rotary hinge mechanism 20 is assembled. The angle range (β _m ) rotated with respect to 2 is approximately 90 °. In addition, a first guard member 69 for protecting the FPC 66 passes through the inside of the ring portion 46 of the outer peripheral ring plate 45 between the fixed plate 31 and the first rotating plate 32 in the first opening 40. It is arranged in a sandwiched state.

On the other hand, the angle range of the second opening 54 is 45 °, which is half the maximum angle (β _m / 2) at which the grip 4 is rotated with respect to the main body 2, and at least a part of the first opening 54. 45 ° + α is obtained by adding an overlap angle α for overlapping the opening 40. In addition, a second guard member 70 for protecting the harness is disposed in the second opening 54 so as to be sandwiched between the pair of rotating plates 32 and 33.

  The first opening 40 and the second opening 54 are configured such that the first opening 40 and the one end 40 a of the first opening 40 are within an angular range in which the pair of rotating plates 32 and 33 are rotated with respect to the fixed plate 31. A part so as to form an overlap portion 67 between the other end 54 b of the second opening 54 or between the other end 40 b of the first opening 40 and one end 54 a of the second opening 54. Are superimposed.

  As described above, in the rotating hinge mechanism 20, the overlap portion in which the first opening 40 and the second opening 54 overlap in the angular range in which the grip portion 4 is rotated with respect to the main body portion 2. 67 is formed, it is possible to gently bend the harness 66 routed between the main body portion 2 and the grip portion 4 at the overlap portion 67, and through the overlap portion 67. The harness 66 can be easily routed.

  Further, in the rotating hinge mechanism 20, the folding width of the harness 66 is not affected by the gap S formed between the fixed plate 31 and the first rotating plate 32, so that the gap S is narrowed. It is also possible to reduce the thickness of the mechanism itself.

  Therefore, in the digital video camera 1 having such a rotating hinge mechanism 20, the entire apparatus is further reduced in size while maintaining the degree of freedom of the harness 66 routed between the main body 2 and the grip 4. Can be achieved. In addition, it is possible to prevent the harness 66 from being caught, disconnected, cut, or the like when the grip portion 4 is rotated with respect to the main body portion 2. In particular, when a double-sided flexible printed wiring board is used as the harness 66, the number of wirings is increased and the bending resistance is inferior to that of a single-sided flexible printed wiring board. Further, in this digital video camera 1, since the harness 66 can be routed after the rotary hinge mechanism 20 is assembled, it is possible to reduce the manufacturing cost.

  The digital video camera 1 has a configuration in which the fixed plate 31 is attached to the grip portion 4 side and the pair of rotating plates 32 and 33 are attached to the main body portion 2 side. It is also possible to adopt a configuration in which the fixed plate 31 is attached to the main body portion 2 side and the pair of rotating plates 32 and 33 are attached to the grip portion 4 side.

  Further, in addition to the FPC described above, when a harness-free harness (electric wire) is used in addition to the above-described FPC, the harness becomes stiffer than the conventional one. It is effective.

  Note that the present invention is not limited to the digital video camera 1 in which the grip portion 4 is rotatably attached to the main body portion 2 via the rotary hinge mechanism 20. The mechanism 20 can be widely applied to electronic devices in which a rotating part is rotatably attached to a main body part in addition to such an imaging device such as a digital video camera or a digital still camera.
