[Technical Field]

[0001] The present invention relates to an imaging device with a detachable cooling device. [Background technology]

[0002] Conventionally, imaging devices have been provided with a heat dissipation structure to suppress temperature rise, as the amount of heat generated increases due to increased power consumption associated with higher functionality and the miniaturization of electronic components.

[0003] Patent Document 1 discloses a configuration for cooling the interior and exterior of an imaging device by forming an intake port and an exhaust port in the rear cover of the imaging device and providing a duct between the exterior side of the rear cover and the interior side of a display unit located further on the exterior.

[0004] Patent Document 2 discloses a configuration that includes an intake and exhaust port that leads to the inside of an imaging device and a blower that creates an air flow in the internal space of the imaging device when attached to the imaging device, thereby increasing the portability of the imaging device and cooling the inside and exterior of the imaging device as needed.

[0006] However, the configuration of Patent Document 1 does not allow for a detachable blower that passes air through the duct, making it impossible to improve cooling capacity. Also, the placement of the intake and exhaust ports is limited to within the rear cover, limiting the flexibility of the placement of the intake and exhaust ports.

[0007] In the configuration of Patent Document 2, the air intake of the imaging device is provided in the tripod mounting means, which limits the placement of the air intake. In addition, no duct is provided inside the imaging device, which means that the air from the blower means is easily diffused.

[0026] The tripod mount 123 is provided on the bottom surface of the camera body 100 and is an attachment member used when attaching an external accessory that can be attached to the camera body 100, such as an external cooling accessory 200, which will be described later.

[0027] The battery cover 124 is a cover for housing a battery (not shown) and is detachably attached to the bottom exterior member 132.

[0028] The rear exterior member (first exterior member) 125 is an exterior member that constitutes the rear surface (first surface) of the exterior of the housing of the camera body 100, and is made of metal, polycarbonate, etc. The rear exterior member 125 includes a body air intake (first opening) 125a provided on the bottom side of the camera body 100, and a storage section exterior surface (storage surface) 125ba that is part of the rear surface and that stores the rear display section 101.

[0029] Side exterior member (second exterior member) 126 is an exterior member that forms the left side (second surface) of the exterior of the housing of camera body 100 when viewed from the back of camera body 100, and is made of metal, polycarbonate, etc. Side exterior member 126 is provided with a body exhaust port 126a.

[0030] The bottom exterior member 132 is an exterior member that forms the bottom surface of the exterior of the housing of the camera body 100, and is made of metal, polycarbonate, or the like.

[0031] 2 is an explanatory diagram of an external cooling accessory (cooling device) 200 that can be attached to and detached from the camera body 100. Fig. 2(a) is a front perspective view of the external cooling accessory 200, and Fig. 2(b) is a cross-sectional view taken along line AA in Fig. 2(a).

[0032] The external cooling accessory 200 includes an accessory exterior 201, a tripod screw 202, a tripod screw operating unit 203, a fan (air blowing means) 204, an accessory air intake 205, an accessory exhaust 206, and an accessory cushion member (third sealing member) 207. By operating the tripod screw operating unit 203 and rotating the tripod screw 202, the camera body 100 and the external cooling accessory 200 can be fixed together. The accessory cushion member 207 is provided on the upper surface of the accessory exhaust 206.

[0033] By driving the fan 204, a second duct (second flow path) 208 is formed inside the external cooling accessory 200 from an accessory intake port 205 indicated by arrow F via the fan 204 to an accessory exhaust port 206. A battery (not shown) is detachably mounted inside the external cooling accessory 200. The external cooling accessory 200 includes a power terminal 252a and a communication terminal 252b. The power terminal 252a enables power supply between the camera body 100 and the external cooling accessory 200. The communication terminal 252b enables communication between the camera body 100 and the external cooling accessory 200.

[0034] Figure 3 is an external view of the camera body 100 and the external cooling accessory 200. Figure 3(a) is a view of the camera body 100 from the front when the external cooling accessory 200 is not attached. Figure 3(b) is a view of the camera body 100 from the front when the external cooling accessory 200 is attached, i.e., a view of the camera system made up of the camera body 100 and the external cooling accessory 200.

[0035] 3(a) is used when there is no need to cool the inside of the camera body 100. Because there is no need to attach the external cooling accessory 200, there is an advantage that the portability of the camera body 100 is excellent for users who do not need the camera body 100 to be cooled.

[0036] External cooling accessory 200 is fixed by removing battery cover 124 from camera body 100 and engaging tripod mount 123 with tripod screw 202. When fan 204 is driven, a flow path is formed from accessory intake port 205 to body exhaust port 126a, as shown by arrow F. This allows heat inside camera body 100 to be cooled when fan 204 is driven.

[0037] As explained above, external cooling accessory 200 only needs to be attached to camera body 100 when cooling is required inside camera body 100. By giving the user the option of attaching or detaching external cooling accessory 200 depending on the user's application, it is possible to achieve both portability of camera body 100 and cooling performance as needed.

[0038] Figure 4 is a system diagram of the camera body 100 and the external cooling accessory 200. Figure 4(a) is a system diagram of the camera body 100 in the state shown in Figure 3(a), and Figure 4(b) is a system diagram of the camera body 100 and the external cooling accessory 200 in the state shown in Figure 3(b).

[0039] The main circuit board 142 is a printed wiring board (PWB) on which various components, such as a CPU 143, which is a heat-generating component, are mounted. The CPU 143 controls the overall operation of the camera body 100, controlling each functional block of the camera body 100 and performing the necessary calculations in accordance with a computer program loaded from memory 152. The power supply 150 supplies power to each circuit within the camera body 100. The imaging element 141 is composed of a CCD or CMOS sensor, and performs photoelectric conversion of an optical image of a subject to output an image signal. The image signal output from the imaging element 141 is converted into image data by the image processing unit 151 and output to the CPU 143. The shutter 156 is disposed in front of the imaging element 141 and adjusts the exposure time of the imaging element 141. The shutter control unit 154 drives the shutter 156 based on a signal input from the CPU 143. When the mode changeover switch 104 is operated by the user, the operation detection unit 157 outputs a signal to the CPU 143 and changes the photographing conditions such as exposure and shutter speed.

[0040] The user can select a desired video capture mode from multiple video capture modes by operating the mode selector switch 104. Video capture modes include, for example, a high-quality mode and a low-quality mode. When capturing video in the low-quality mode, the amount of heat generated by electronic components such as the image sensor 141 and CPU 143 is small, allowing for a longer video capture time. On the other hand, when capturing video in the high-quality mode, the processing load on the image sensor 141, CPU 143, etc. is heavy, resulting in a larger amount of heat generated by electronic components and media (not shown). If the amount of heat generated becomes too great and exceeds the allowable temperature, thermal runaway or a shortened product lifespan may occur, forcing the video capture time to be shortened. In such cases, an external cooling accessory 200 can be attached to the camera body 100.

[0041] External cooling accessory 200 includes power supply 250, control board 251, and connection terminal 252, and is connected to camera body 100 via connection terminal 252 and connection terminal 150 provided on camera body 100 so that power can be supplied and communication can be performed. Power supply 250 supplies power to each circuit unit within camera body 100 via connection terminal 252. Control board 251 drives fan 204 based on a signal input from CPU 143.

[0042] The internal configuration and cooling method of the camera body 100 will be described below. Fig. 5 is an explanatory diagram of the inside of the camera body 100. Fig. 5(a) is an exploded perspective view of the inside of the camera body 100 when the external cooling accessory 200 is not attached, as viewed from the front. Fig. 5(b) is a perspective view of the inside of the camera body 100 when the external cooling accessory 200 is attached, as viewed from the front. Fig. 5(c) is a cross-sectional view taken along line BB in Fig. 5(b). Fig. 5(d) is a partial enlarged view of part C in Fig. 5(c).

[0043] The rear exterior member 125 includes a storage compartment interior surface 125bb, which is the back side of the storage compartment exterior surface 125ba, and a wall surface 125c formed to protrude in the Z direction from the storage compartment interior surface 125bb. A sheet metal member (heat dissipation member) 127 is disposed inside the housing, facing the rear surface of the camera body 100 (the surface of the rear exterior member 125 facing the storage compartment exterior surface 125ba) and the surface opposite (the surface of the rear exterior member 125 facing the storage compartment interior surface 125bb). The outer periphery of the sheet metal member 127 is formed along the wall surface 125c of the rear exterior member 125. In this embodiment, the sheet metal member 127 is assumed to be made of an aluminum alloy, but this is not limited to this. A first cushion member (first sealing member) 128 is attached to the wall surface 125c, and is disposed between the sheet metal member 127 and the wall surface 125c. The sheet metal member 127 is fixed to the wall surface portion 125c in the Z direction by fastening members 129 via the first cushion member 128.

[0044] The first CPU (second heat generating member) 143a and the second CPU (first heat generating member) 143b are disposed on the sheet metal member 127 side of the main circuit board 142 in the Z direction. The first CPU 143a and the second CPU 143b have different amounts of heat generation. In this embodiment, the first CPU 143a generates less heat than the second CPU 143b. A first heat dissipation member (second heat dissipation member) 144a is disposed between the sheet metal member 127 and the first CPU 143a, and a second heat dissipation member (first heat dissipation member) 144b is disposed between the sheet metal member 127 and the second CPU 143b. The first heat dissipation member 144a is in thermal contact with the first CPU 143a and transfers heat generated from the first CPU 143a to the sheet metal member 127. The second heat dissipation member 144b is in thermal contact with the second CPU 143b and transfers heat generated from the second CPU 143b to the sheet metal member 127. In this embodiment, the first heat dissipation member 144a is assumed to be heat-conductive rubber and the second heat dissipation member 144b is assumed to be a graphite sheet, but this is not limited to this. The side exterior member 126 has a protrusion 126b formed on the back side of the surface on which the main body exhaust port 126a is provided, protruding in the X direction. A second cushion member (second sealing member) 130 is attached to the tip surface of the protrusion 126b.

[0045] In this embodiment, by forming body air inlet 125a in rear exterior member 125 and body exhaust outlet 126a in side exterior member 126, it is possible to prevent rear exterior member 125 from becoming too large. This makes it possible to reduce the weight of camera body 100. Furthermore, by forming body air inlet 125a and body exhaust outlet 126a in separate exterior members, it is possible to increase the degree of freedom in arranging body air inlet 125a and body exhaust outlet 126a.

[0046] In this embodiment, body intake vent 125a is provided on the bottom surface, where there are fewer operating members than on the top and back surfaces described in Fig. 1, and body exhaust vent 126a is provided on the left side when viewed from the back of camera body 100. This allows the user to operate camera body 100 without blocking body intake vent 125a and body exhaust vent 126a.

[0047] The thickness of first cushion member 128 is greater than the clearance in the Z direction between wall surface portion 125c and sheet metal member 127. As a result, when sheet metal member 127 is fixed to wall surface portion 125c by fastening member 129, first cushion member 128 is always pressed in the Z direction. With the above configuration, first duct (first flow path) 131 is formed in camera body 100 from body intake port 125a to junction portion 127a via the outer circumferential shape of sheet metal member 127. First duct 131 can ensure internal sealing by first cushion member 128 and second cushion member 130 being pressed.

[0048] The accessory cushion member 207 is disposed so as to overlap the outer periphery of the main body air intake 125a in the Y direction. The thickness of the accessory cushion member 207 is greater than the clearance in the Y direction between the accessory exterior 201 and the rear exterior member 125 and the bottom exterior member 132. As a result, when the external cooling accessory 200 is attached to the camera body 100, the accessory cushion member 207 is always pressed in the Y direction. With the above configuration, a tight seal is ensured from the accessory exhaust port 206 to the main body air intake 125a when the fan 204 is driven, and a flow path indicated by arrow F in the figure can be formed from the accessory air intake 205 to the first duct 131. Note that, to ensure this flow path, the clearance in the Z direction between the storage compartment interior surface 125bb and the sheet metal member 127 that constitutes the first duct 131 is made greater than the thickness of the sheet metal member 127.

[0049] Heat generated from the first CPU 143a and the second CPU 143b is transferred to the sheet metal member 127 via the first heat dissipation member 144a and the second heat dissipation member 144b, respectively. The heat from the sheet metal member 127 is cooled by air flowing from the accessory air intake 205 to the first duct 131. In a shooting mode in which the amount of heat generated by the heat source of the camera body 100, including the first CPU 143a and the second CPU 143b, is small, the external cooling accessory 200 is not attached. On the other hand, in a shooting mode in which the amount of heat generated is large, the external cooling accessory 200 is attached and the fan 204 is driven, thereby constructing a camera system. This makes it possible to improve heat dissipation while ensuring the portability of the camera body 100, thereby increasing the user's options.

[0050] Figure 6 is a side view of the camera body 100. Figure 6(a) shows the state where the terminal cover 105 has been removed, and Figure 6(b) shows the state where the terminal cover 105 has been attached.

[0051] Camera body 100 has a USB terminal (first connection portion) 145 and an HDMI (registered trademark) terminal (second connection portion) 146. USB terminal 145 and HDMI terminal 146 are arranged so as to be exposed from openings in side surface exterior member 126. USB terminal 145 and HDMI terminal 146 are protected by terminal cover 105 when not in use. In this embodiment, HDMI terminal 146 has a larger area (projected area) on side surface exterior member 126 than USB terminal 145. Body exhaust port 126a is arranged behind USB terminal 145 in the Z direction and above HDMI terminal 146 in the Y direction. By arranging body exhaust port 126a in the space created by the difference in area between USB terminal 145 and HDMI terminal 146, it is possible to prevent terminal cover 105 from expanding rearward in the Z direction and reduce the size and weight of camera body 100 in the Z direction. The USB terminal 145 and the HDMI terminal 146 may be mounted on the main circuit board 142 or on a circuit board (not shown) that is arranged parallel to the main circuit board 142 .

[0052] Fig. 7 is an internal view of the camera body 100. Fig. 7(a) is a cross-sectional view taken along line DD in Fig. 6(b). Fig. 7(b) is an enlarged view of part E in Fig. 7(a). Fig. 7(c) is an exploded perspective view of the interior of the camera body 100 as seen from the rear.

[0053] In this embodiment, the second CPU 143b generates more heat than the first CPU 143a. The wall surface portion 125c forms the wall surface of the first duct 131 and includes a bent portion 125d that forcibly bends the air entering through the main body air inlet 125a toward the main body air outlet 126a. The second CPU 143b is disposed near the main body air inlet 125a side relative to the bent portion 125d. Generally, the pressure is high on the outside of the flow path and low on the inside, resulting in a high flow rate on the inside and a low flow rate on the outside. As indicated by arrow F, the first duct 131 forms a flow path in which the second CPU 143b side has a high flow rate on the inside and the first CPU 143a side has a low flow rate on the outside. As described above, by increasing the flow rate near the second CPU 143b, which generates a large amount of heat, the amount of heat dissipated by the second CPU 143b can be efficiently increased within a limited flow path.

[0054] Second cushion member 130 is disposed in the X direction between junction 125e of rear exterior member 125, junction 127a of sheet metal member 127, junction 128a of first cushion member 128, and protrusion 126b of side exterior member 126. When side exterior member 126 is attached to camera body 100 in the X direction, the thickness of second cushion member 130 is greater than the clearance in the X direction between protrusion 126b and junctions 125e, 127a, and 128a. As a result, when side exterior member 126 is attached to camera body 100 in the X direction, second cushion member 130 is always pressed in the X direction. With the above configuration, sealing is ensured from the first duct 131 to the main body exhaust port 126a when the fan 204 is driven, and it is possible to form a flow path indicated by arrow F from the main body intake port 125a to the main body exhaust port 126a, as shown in Figure 7(a).

[0055] The multi-controller 109, rear electronic dial 110, SET button 111, first to fourth button groups 113-116, grip unit 121, etc. are arranged in positions that do not overlap with the first duct 131 when viewed from the Z direction. Furthermore, the first CPU 143a, which generates less heat than the second CPU 143b, is arranged in a position close to the grip unit 121. Furthermore, in this embodiment, the thermal conductivity of the first heat dissipation member 144a is set lower than that of the second heat dissipation member 144b. In this way, the first CPU 143a and second CPU 143b, which are heat sources, and the sheet metal member 127, which receives their heat, are intentionally placed farther away in the X and Y directions from components that the user touches.
