  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1A is a perspective view of a digital video camera as an example of an embodiment of an imaging apparatus according to the present invention as seen from the back side, and FIG. 1B is a perspective view of the digital video camera shown in FIG. FIG. FIG. 2 is a perspective view showing a state in which a battery is attached to the digital video camera shown in FIG. In the figure, Z denotes the optical axis, and the subject side (front side) is described as + Z direction, and the photographer side (back side) is described as −Z direction.

  As shown in FIG. 1, a digital video camera 100 according to the present embodiment (hereinafter referred to as camera 100) has a lens unit 300 disposed on the front side, and an operation such as manual focusing is performed on the outer periphery of the lens unit 300. A possible operating ring 103 is provided. A display unit 101 made of an LCD or the like is supported on the left side as viewed from the back side of the camera 100 so as to be openable and closable.

  On the back side of the camera 100, a finder unit 102, a battery chamber 104, a battery release switch 105, a recording button 116, battery mounting guides 106a and 106b, a battery chamber inlet 107, and battery lock units 113a and 113b are provided. . The battery mounting guides 106 a and 106 b are not shown in the figure, but the same is provided on the opposite side in the battery chamber 104.

  A first grip portion 114 having a grip main surface 114a to be gripped by the user is provided on the left side when the camera 100 is viewed from the front side. Main intake ports 108a and 108b are provided on the front side of the camera 100 of the first grip portion 114, and a second grip portion 115 and an exhaust port 109 are provided on the back side of the camera 100 of the first grip portion 114. ing. Further, on the top surface of the camera 100, a microphone unit 110 is provided on the front side, and a zoom key 111 is provided on the back side.

  A first grip belt holder 117 is provided on the first grip portion 114 side of the exhaust port 109 in the region of the second grip portion 115. The first grip belt holder 117 is formed with a hole 117a for passing a grip belt (not shown) and a hole 117b for passing a strap belt (not shown), and the hole 117b is disposed above the hole 117a. Has been.

  Further, a second grip belt holder 118 is provided on the main gripper port 108b side of the first grip portion 114. The second grip belt holder 118 is formed with a hole 118a through which the grip belt is passed and a hole 118b through which the strap belt is passed, and the hole 118b is arranged above the hole 118a.

  The grip belt passed through the hole portion 117a and the hole portion 118a is a belt for holding a hand for the user to grip the camera 100. Further, both ends of the strap belt are passed through the hole 117b and the hole 118b, and each is fixed to the camera 100. As a result, the user can carry the strap belt on the shoulder.

  Further, the hole 117a through which the grip belt passes and the hole 117b through which the strap belt pass are formed in the first grip belt holder 117 which is the same component, and are arranged in the vicinity. This reduces the number of places where the camera 100 requires strength compared to forming the hole 117a and the hole 117b at separate positions, and enables downsizing. Similarly, the hole 118a through which the grip belt passes and the hole 118b through which the strap belt pass are also formed in the second grip belt holder 118, which is the same component, and are arranged in the vicinity. This reduces the number of places where the camera 100 needs strength compared to disposing the hole 118a and the hole 118b separately from each other, and enables miniaturization.

  The holes 117b and 118b through which the strap belt is passed are arranged on the upper side of the camera 100 in the height direction of the holes 117a and 118a through which the grip belt is passed. The hole 117b and the hole 118b through which the strap belt is passed have a long hole shape that is long in the height direction (vertical direction) of the camera 100 perpendicular to the optical axis (Z axis). The hole 117a and the hole 118a through which the grip belt is passed are formed in a long hole shape whose upper end side is inclined outward in the width direction of the camera 100 with respect to the hole 117b and the hole 118b through which the strap belt is passed. Thereby, the user can use each belt without impairing the feeling of use of each of the grip belt and the strap belt.

  Further, the hole 117b through which the strap belt is passed and the hole 118b are arranged apart from each other in the vertical direction of the camera 100 with the optical axis (Z axis) interposed therebetween. Since the optical axis is arranged in the vicinity of the approximate center of gravity of the camera housing 200, when the user carries the camera 100 using the strap belt, the camera 100 is stable and easy to carry.

  The camera 100 sucks outside air from the direction of arrow A at the battery chamber inlet 107, sucks outside air from the directions of arrows B and C at the main inlets 108 a and 108 b, and exhausts the air in the direction of arrow D at the outlet 109. The inside of the camera 100 is cooled. The D direction is an outer direction in the width direction of the camera 100 that is substantially orthogonal to the pressing direction (optical axis direction) of the recording button 116. The recording button 116 corresponds to an example of the operation button of the present invention.

  The grip main surface 114a is a part of the first grip portion 114, and is a surface on which the palm of the user mainly contacts. The second grip portion 115 includes an extending portion 115a provided extending in the D direction from the surface on which the recording button 116 of the camera 100 is disposed, and the extending portion 115a is the main grip surface when viewed from the optical axis direction. It has a shape protruding in the D direction from 114a. The user grips the second grip portion 115 with the thumb and forefinger, grips the palm to the main grip surface 114a, and grips the first grip portion 114 with each finger from the index finger to the little finger, thereby making the camera 100 easy. It is possible to grip. Further, the recording button 116 can be easily pushed and operated while the camera 100 is gripped.

  Further, since the exhaust port 109 which is a ventilation portion is disposed in the second grip portion 115, the exhaust port 109 is disposed in a space between the thumb and the index finger when the camera 100 is gripped. . For this reason, when the user grips the camera 100, the exhaust port 119 can be prevented from being accidentally blocked. Specifically, the first grip belt holder 117 is disposed on the subject side from the exhaust port 109 in the region of the second grip portion 115, and the grip main surface is interposed between the first grip belt holder 117 and the second grip belt holder 118. 114a is arranged.

  Accordingly, the first grip belt holder 117 is disposed between the user's index finger and the exhaust port 109, and the user's index finger gripping the camera 100 can be prevented from blocking the exhaust port 109. Further, the grip belt itself (not shown) is arranged so as not to block the exhaust port 109.

  Further, the first grip belt holder 117 is configured to cover at least a part of the surface of the metal member for ensuring strength with a resin. At least a part includes a portion that may be touched by a user's hand or the like. Since the resin has low thermal conductivity, the first grip belt holder 117 is not easily heated even when the hot air exhausted from the exhaust port 109 hits the first grip belt holder 117. As a result, the first grip belt holder 117 is configured to prevent the user from feeling uncomfortable due to heat even when the user touches the first grip belt holder 117 while ensuring strength.

  The battery lock portions 113 a and 113 b are urged in the −Z direction by an elastic member (not shown) and protrude from the battery chamber 104 in a normal state. The battery release switch 105 is a slide switch that can be operated in the + Z direction, and the battery release switch 105 and the battery lock portions 113a and 113b are integrated. For this reason, along with the sliding operation of the battery release switch 105, the battery lock portions 113a and 113b can be retracted to a position where they do not protrude from the battery chamber 104.

  As shown in FIG. 2, the battery 112 is detachably attached to the battery chamber 104. In such a mounted state, movement of the battery 112 in the −Z direction is restricted by engagement of a claw portion (not shown) provided in the battery 112 with the battery mounting guides 106 a and 106 b provided in the battery chamber 104. The

  Further, the battery lock portions 113 a and 113 b protruding from the battery chamber 104 support the bottom surface portion 112 a of the battery 112, so that the battery 112 is held in the battery chamber 104. In this state (FIG. 2), the battery chamber intake 107 is exposed to the outside, so that outside air can be sucked from the battery chamber intake 107 even when the battery 112 is attached.

  Next, the internal structure of the camera 100 will be described with reference to FIGS. 3A is a perspective view of the internal structure of the camera 100 as viewed from the back side, and FIG. 3B is a perspective view of the internal structure of the camera 100 as viewed from the front side. FIG. 4 is a partially enlarged view of FIG.

  As shown in FIG. 3, the camera housing 200 is provided with holder mounting bosses 201a to 201k and sensor mounting bosses 202a to 202c for screwing a holder metal plate 500 (see FIG. 7) described later. As shown in FIG. 4, concentric concave portions 218a to 218c that are slightly larger than the outer shape of the sensor mounting bosses 202a to 202c are provided outside the sensor mounting bosses 202a to 202c. Adjustment coil springs 216a to 216c are attached to the recessed portions 218a to 218c so as to fit along the outer shapes of the sensor attachment bosses 202a to 202c.

  In addition, the imaging unit 260 is positioned on the rear end face of the camera housing 200 by fitting the positioning holes 210a and 210b of the sensor mounting plate 208 into the positioning pins 203a and 203b provided in the camera housing 200. Installed in a state. The image sensor 206 mounted on the sensor substrate 207 is fixed to the sensor mounting plate 208 by an adhesive or the like and integrated.

  The connection connector 217 mounted on the sensor board 207 is electrically connected to a main board 901 (see FIG. 9) described later, and can send image information obtained from the image sensor 206 to the main board 901. . A part of the surface of the sensor substrate 207 opposite to the imaging element 206 is a copper foil exposed portion 212, and the copper foil exposed portion 212 has a sheet-like heat conduction that is slightly smaller than the copper foil exposed portion 212. An adhesive member 213 is affixed. The heat radiating fin 214 is attached to the heat conductive adhesive member 213 so that a part or all of the flange surface thereof overlaps with the image sensor 206 in the optical axis direction. As a result, the radiating fin 214 is thermally connected to the copper foil exposed portion 212 via the heat conductive adhesive member 213, and the heat generated in the sensor substrate 207 is transferred to the radiating fin 214.

  The imaging unit 260 attached to the camera housing 200 is temporarily fixed by inserting the adjustment screws 215a to 215c into the through holes 209a to 209c of the sensor attachment plate 208 and fastening them to the sensor attachment bosses 202a to 202c. The Then, after adjusting the angle of the imaging unit 260 in this state, the imaging unit 260 is permanently fixed to the camera housing 200 with an adhesive or the like.

  Next, a method for adjusting the angle of the imaging unit 260 will be described with reference to FIG. I will explain. 5A is a rear view of the camera housing 200 in a state where the imaging unit 260 is temporarily fixed, FIG. 5B is an enlarged cross-sectional view taken along line MM in FIG. 5A, and FIG. FIG. 6 is an enlarged cross-sectional view taken along line MM in FIG. 5A when the angle of the imaging unit 260 is adjusted.

  In the state of FIG. 5B, the imaging unit 260 receives the urging force in the −Z direction by the adjustment coil spring 216a. When the adjustment screw 215a is loosened in this state, the imaging unit 260 is also pushed up by the biasing force of the adjustment coil spring 216a, and the portion (N axis) supported by the adjustment screws 215b and 215c shown in FIG. As a result, the inclination shown in FIG. 5C is obtained.

  Similarly, when the adjustment screws 215b and 215c are loosened, the imaging unit 260 is pushed up by that amount by the urging force of the adjustment coil springs 216b and 216c, and an inclination is generated. In this way, by adjusting the amount of looseness of the adjustment screws 215a to 215c, the imaging unit 260 can be adjusted to an arbitrary position and posture.

  6A is a perspective view showing a state in which the holder metal plate 500 and the sensor duct unit 400 are attached to the camera housing 200 to which the imaging unit 260 is attached, and FIG. 6B is an exploded perspective view of the sensor duct unit 400. FIG.

  As shown in FIG. 6 (a), the holder metal plate 500 is attached by screws 501a to 501k (screws 501g to 501k are not shown) at positions corresponding to the holder mounting bosses 201a to 201k (see FIG. 3) of the camera housing 200. It has been. In addition, the sensor duct unit 400 is attached to the holder metal plate 500 by screws 601 a to 601 c so as to cover the imaging unit 260.

  As shown in FIG. 6B, the sensor duct unit 400 includes a sensor duct 401, a sensor duct lid 402, an elastic member 404, an intake port elastic member 412, and an exhaust port elastic member 413. Is provided with an opening 403. The opening 403 has an opening area in which the tip of the fin portion 214b of the heat radiating fin 214 can be inserted in the assembled state. The elastic member 404 is attached to the sensor duct lid 402 via a double-sided tape (not shown).

  The opening area of the opening 407 of the elastic member 404 is larger than the opening 403 of the sensor duct lid 402. The elastic member 104 is disposed so as to surround the opening 403 along the periphery of the opening 403 of the sensor duct lid 402. The sensor duct 401 and the sensor duct lid 402 are integrated by fastening the screws 406a to 406b with the bosses 409a to 409b through the through holes 408a to 408b of the sensor duct lid 402.

  The sensor duct 401 is provided with an intake port 410 and an exhaust port 411. The intake port 410 and the exhaust port 411 are respectively provided with an intake port elastic member 412 and an exhaust port elastic member 413 having a low heat transfer coefficient, such as sponge. Is affixed with a double-sided tape (not shown). The intake port 410 corresponds to the battery chamber intake port 107.

  Next, a heat dissipation structure of the imaging unit 260 using the sensor duct unit 400 will be described with reference to FIGS. FIG. 7 is a rear view of FIG. FIG. 8A is an enlarged sectional view taken along the line P-P in FIG.

  As shown in FIG. 8A, the inner wall surface of the sensor duct 401 is a concave surface that is opposed to the radiating fin 214 in the Z direction and has a concave shape in order to secure a gap with the tip of the fin portion 214b. The part 401a and the flat part 401b which is an area | region other than that are provided. The distance h0 from the tip of the fin portion 214b to the concave surface portion 401a is set to a distance larger than the amount of displacement in the optical axis direction of the imaging unit 260 that is displaced by adjusting the tilt angle of the imaging unit 260. Specifically, a sufficient distance is secured so that the fin portion 214b and the concave surface portion 401a do not come into contact with each other due to the movement of the tip of the fin portion 214b by adjusting the tilt angle of the imaging unit 260 or the deformation of the concave surface portion 401a due to impact or the like. Yes.

  In addition, the elastic member 404 is assembled in a charged state between the flange surface 214 a of the radiating fin 214 and the sensor duct lid 402. The charge amount of the elastic member 404 is sufficiently ensured so that the hermeticity with respect to the outside is maintained regardless of the direction in which the image pickup unit 260 moves including ± Z in accordance with the angle adjustment described above.

  As shown in FIG. 7, the sensor duct unit 400 is connected to the battery chamber inlet 107 (see FIG. 1A) via the inlet elastic member 412 at the inlet 410. For this reason, the air sucked from the battery chamber intake port 107 flows into the intake port 410 in the direction of arrow E in FIG. 7, and passes through the heat radiation fins 214 on the way to take the heat of the sensor substrate 207 (FIG. 8A )), Flows in the direction of the arrow as it is, and is exhausted from the exhaust port 411 in the direction of the arrow F.

  As shown in FIG. 8B, when the plane portion 401c is entirely separated from the heat radiating fins 214, when the inflow air passes through the region of the heat radiating fins 214, the air flow resistance difference causes the difference between the air radiating fins 214. Many flows in the region between the tip of the fin portion 214b and the flat portion 401c. On the other hand, as shown in FIG. 8A, the flow of air is limited by providing the concave surface portion 401a, and the air can be more positively applied to the fin portion 214b of the radiating fin 214.

  Further, as shown in FIG. 8C, a rib 401d is formed in the sensor duct 401 in the direction perpendicular to the air flow direction, for example, to prevent the air flow between the area of the concave surface portion 401a and the fin portion 214b. Then, compared to FIG. 8A, it becomes difficult for air to flow in the region of the distance h0. Thereby, air can be positively applied to the fin part 214b. The rib 401d is disposed between adjacent fin portions 214b.

  As described above, the distance h1 perpendicular to the optical axis direction of the fin portion 214b and the rib 401d is also affected by the movement of the tip of the fin portion 214b by the angle adjustment of the imaging unit 260, the deformation of the concave surface portion 401a due to an impact, or the like. In consideration, it is desirable to secure a sufficient distance.

  Next, a heat dissipation structure of the main board 901 using the main duct 902 will be described with reference to FIGS. FIG. 9 is an exploded perspective view showing a state in which the main board 901, the main duct 902, the main duct lid 903, and the cooling fan 904 are further attached from the state of FIG. 10A is a view of the assembly of FIG. 9 as viewed from the direction of the arrow X, and FIG. 10B is a cross-sectional view taken along the line QQ of FIG. 10A. In FIG. 10A, the main duct lid 903 is not shown for convenience of explanation.

  As shown in FIG. 9, the main substrate 901 is disposed on a plane that is substantially parallel to the side surface of the camera housing 200, that is, on a plane that intersects substantially at right angles to the plane on which the sensor substrate 207 is disposed. The side of the main substrate 901 facing the holder sheet metal 500 is thermally connected to the holder sheet metal 500 via a heat conductive elastic member (not shown). Similarly, the side of the main board 901 facing the main duct 902 is thermally connected to the main duct 902 via a heat transfer elastic member (not shown).

  As a result, the heat generated in the main board 901 is divided into two paths: a path that diffuses into the camera 100 through the holder metal plate 500 and a path that is exhausted to the outside by forced air cooling through the main duct 902. Heat is dissipated. Further, in order to further enhance the effect of diffusing heat into the camera 100 through the holder sheet metal 500, the holder sheet metal 500 is made of a material having a high heat transfer coefficient such as an aluminum alloy, and around the camera casing 200 as much as possible. A lot of area is taken to surround. The main duct 902 corresponds to an example of the air duct of the present invention.

  The main duct 902 includes radiating fins 902a and flat portions 902b (FIG. 10B) that are substantially parallel to the main substrate 901 and on which the radiating fins 902a are formed. As shown in FIG. 10B, the main duct lid 903 includes an opening 903a for allowing air to flow between the cooling fan 904, a flat portion 903b facing the heat radiating fin 902a, and a heat radiating fin 902a of the main duct 902. And a flat portion 903c facing the non-exposed region. Note that the cooling fan 904 is constituted by, for example, a centrifugal fan. The cooling fan 904 is attached to the main duct 902 so that the rotation axis P is substantially orthogonal to the main board.

  Here, the distance from the flat portion 902b of the main duct 902 to the flat portion 903b of the main duct lid 903 (height of the radiation fin 902a) is h2, and the distance from the flat portion 902b to the flat portion 903c of the main duct lid 903 is h3. And

  The air flow in the main duct 902 is first sucked from the directions of arrows B and C shown in FIG. 10B through the air inlets 902c and 902d, and the sucked air flows into the flat portion 902b and the flat portion 903b. Pass through the space between. The air passing through the space between the flat surface portion 902b and the flat surface portion 903b takes heat from the radiating fin 902a, passes through the space between the flat surface portion 902b and the flat surface portion 903c, flows to the cooling fan 904, and exhausts the air outlet 904a. Is exhausted in the direction of arrow D. The intake ports 902c and 902d correspond to the intake ports 108a and 108b in FIG. 1B, and the exhaust port 904a corresponds to the exhaust port 109 in FIG. 1B.

  By the way, since the ventilation resistance of air is mainly determined by the cross-sectional area of the flow path, the cross-sectional integral flow path of the heat radiation fin 902a becomes narrow in the region where the heat radiation fin 902a is disposed. For this reason, if the flow path cross-sectional area of the area where the heat dissipating fins 902a are disposed is the same as the area where the heat dissipating fins 902a are not disposed, the area where the heat dissipating fins 902a are not disposed is the dimension in the cross-sectional integral height direction of the heat dissipating fins Can be suppressed (h2-h3).

  As a result, the cooling fan 904 can be placed close to the optical axis, in other words, at a position lower than the radiation fin 902a, and the main duct 902 including the cooling fan 904 can be downsized. Further, if the heat dissipation structure of the main duct 902 including the cooling fan 904 is downsized and disposed inside the first grip part 114, the first grip part 114 can be brought close to the optical axis, and the position of the center of gravity of the camera 100 As a result, the first grip portion 114 approaches and the ease of holding is improved.

  The main duct 902 is provided with a duct connection opening 905 for connecting to the exhaust port 411 of the sensor duct unit 400. The duct connection opening 905 is disposed on the opposite side of the rotation axis P of the cooling fan 904 with respect to the air flow flowing from the arrow B direction and the arrow C direction in FIG. 10B to the cooling fan 904. Has been. As a result, the air flow from the arrow B direction and the arrow C direction toward the cooling fan 904 and the air flow from the exhaust port 411 of the sensor duct unit 400 toward the cooling fan 904 cool without interfering with each other. Guided to fan 904. For this reason, it becomes possible to efficiently exhaust the air flows from the two directions.

  Further, since the air that has been warmed by passing through the radiation fins 902a flows to the cooling fan 904, it is difficult for the air to flow toward the duct connection opening 905 on the opposite side of the radiation fins 902a with the cooling fan 904 interposed therebetween. . Furthermore, the exhaust port 411 and the duct connection opening 905 are in contact only via the exhaust port elastic member 413 having a lower thermal conductivity than the main duct 902 and the sensor duct 401. For this reason, it is possible to minimize the heat of the main duct 902 from being transmitted to the sensor duct unit 400 via the duct connection opening 905.

  The main duct 902 is formed of an aluminum die cast component having high thermal conductivity and high rigidity. The first grip belt holder 117 and the second grip belt holder 118 are mechanically connected to the main duct 902 with screws or the like and fixed. As a result, the first grip belt holder 117 and the second grip belt holder 118 are mechanically connected to the main duct 902 that is an integral high-rigidity component, and thus have high strength.

  Further, the metal portions of the first grip belt holder 117 and the second grip belt holder 118 are mechanically connected to the main duct 902 with screws or the like in a state where at least one bending process is performed and fixed. Thereby, when the camera 100 is dropped, the impact transmitted from the first grip belt holder 117 and the second grip belt holder 117 to the main duct 902 can be reduced.

  As described above, according to the present embodiment, when the user grips the camera 100, it is possible to prevent the exhaust port 109, which is a ventilation unit, from being accidentally blocked by hand, and to grip the camera 100. Can be made easier.

  The configuration of the present invention is not limited to that exemplified in the above embodiment, and the material, shape, dimensions, form, number, arrangement location, and the like can be changed as appropriate without departing from the scope of the present invention. It is.
