Abstract
Description
[Technical field]
[0001] The present invention relates to an imaging device and an imaging system, and more particularly to a technique for cooling a recording medium attached to an imaging device. [Background technology]
[0002] There is a demand for high image quality of recorded video. In order to meet such needs, when high image quality is attempted by increasing the resolution and the frame rate, the amount of power consumption increases due to the signal processing load inside the imaging device. In particular, the amount of heat generated by the imaging section, image processing section, recording media, etc. increases, and since these generally decrease in performance when they become hot, it is necessary to provide a structure for cooling these inside the imaging device. Therefore, an imaging device that is mainly intended for video shooting (i.e., recording of video) and has a structure for cooling the recording media has been proposed. For example, Patent Document 1 discloses an imaging device that cools the recording media by providing an air-cooling duct so as to overlap with the main surface of the recording media when viewed from a direction perpendicular to the main surface of the recording media. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent Publication No. 2021-34789 Summary of the Invention [Problem to be solved by the invention]
[0004] There is concern that the amount of heat generated by recording media will increase further in the future as the writing bit rate increases to achieve higher image quality. Therefore, it is necessary to efficiently cool the recording media, but at the same time, it is necessary to avoid or suppress the increase in size of the imaging device.
[0005] In contrast, in the imaging device described in Patent Document 1, the structure of the air-cooling duct for cooling the multiple heat-generating parts inside the imaging device is complex, so it is not easy to increase the cooling efficiency of the recording media while avoiding or minimizing the increase in size of the imaging device.
[0006] The present invention has been made in consideration of the above problems, and has an object to provide an imaging device that is capable of efficiently cooling a recording medium while preventing an increase in size. [Means for solving the problem]
[0007] The imaging device of the present invention is an imaging device comprising a gripping portion, a media slot provided inside the gripping portion, an intake port, an exhaust port, a cooling duct connecting the intake port and the exhaust port, and a first heat transfer member that transfers heat from the media slot to the cooling duct, wherein the cooling duct has a cooling fan that flows air inside the cooling duct from the intake port toward the exhaust port, and an intake side duct connected to the intake port and provided so as to overlap at least a portion of the media slot in the gripping portion when viewed from the optical axis direction of the imaging device. Effect of the Invention
[0008] According to the present invention, it is possible to realize an imaging device that is capable of efficiently cooling a recording medium while preventing an increase in size. [Brief description of the drawings]

[0010] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
[0011] First Embodiment Fig. 1 is a perspective view showing the appearance of an imaging system 100 according to the first embodiment. Fig. 1(a) is a front perspective view of the imaging system 100, and Fig. 1(b) is a rear perspective view of the imaging system 100. The imaging system 100 includes an imaging device 102 and a lens barrel 103 attached to the front of the imaging device 102. The lens barrel 103 is configured as a so-called interchangeable lens that can be replaced (attached and detached) with respect to the imaging device 102 depending on the shooting scene. However, the imaging device 102 and the lens barrel 103 may be configured as an integral and inseparable unit.
[0012] For convenience of explanation, an XYZ Cartesian coordinate system is defined for the imaging system 100 as shown in FIG. 1. As shown in FIG. 1, the Z direction is the front-rear direction of the imaging device 102, the Y direction is the height direction of the imaging device 102, and the X direction is the width direction of the imaging device 102. The Z direction is parallel to the optical axis of the lens barrel 103 and perpendicular to the imaging surface of the imaging element 109 (see FIG. 2), and the direction from the imaging system 100 toward the subject (not shown) (the direction from the back side to the front side of the imaging system 100) is defined as the positive direction (+Z). Regarding the X direction, the direction from left to right when the imaging system 100 is viewed from the positive direction of the Z direction is defined as the positive direction (+X). Regarding the Y direction, the direction from the bottom surface toward the top surface of the imaging device 102 is defined as the positive direction (+Y).
[0013] The lens barrel 103 forms an image of incident light on the imaging surface of the imaging element 109 (see FIG. 2). A first intake port 105 and a second intake port 106 for drawing outside air into the inside of the imaging device 102 are provided on the bottom surface of the imaging device 102. In addition, an exhaust port 104 for discharging heat generated inside the imaging device 102 to the outside is provided on the right side surface of the imaging device 102 when viewed from the subject side. The first intake port 105 and the second intake port 106 are connected to the exhaust port 104 by a cooling duct. The configuration of the cooling duct will be described in detail later.
[0014] A recording media insertion port 107 is provided on the left side surface (-X side surface) of the imaging device 102 when viewed from the subject side, for inserting and removing a recording medium (not shown) into and from a media slot provided inside the imaging device 102. In addition, a battery insertion port 108 is provided on the left side of the bottom surface of the imaging device 102 for inserting and removing a battery (not shown).
[0015] The imaging device 102 is provided with a battery cover (not shown) for opening and closing the battery insertion port 108. The imaging device 102 also has a power button, a shutter button, and a menu button and a selection button for performing various settings of the imaging system 100, but these are not directly related to the present invention and therefore are not shown in the drawings and will not be described.
[0016] Fig. 2 is a perspective view showing the configuration of the main parts of the imaging device 102. Fig. 2(a) is a front perspective view of the main parts, and Fig. 2(b) is a rear perspective view of the main parts. Fig. 3(a) is an exploded perspective view of the main parts corresponding to Fig. 2(a), and Fig. 3(b) is an exploded perspective view of the main parts corresponding to Fig. 2(b). Here, the main parts shown are the imaging element 109, the intake duct 110, the control circuit board 111, the exhaust duct 112, the cooling fan 113, the first media slot 114, and the second media slot 115.
[0017] The control circuit board 111 has an imaging element 109 mounted on its +Z side surface, and a first media slot 114 and a second media slot 115 mounted on its opposite -Z side surface. The control circuit board 111 also has various electronic components mounted thereon, such as a control circuit (not shown) that performs overall control of the imaging system 100. The imaging element 109 is, for example, a CMOS sensor, and converts light incident from the lens barrel 103 into an electrical signal to generate an image signal. The first media slot 114 and the second media slot 115 each house a recording medium (not shown). A recording medium (not shown) can be inserted and removed from the first media slot 114 and the second media slot 115 through the recording media insertion port 107. In the following description, when the first media slot 114 and the second media slot 115 are not to be distinguished from each other, they may be simply referred to as "media slots."
[0018] The intake side duct 110, the exhaust side duct 112, and the cooling fan 113 configure a cooling duct that releases heat generated inside the imaging device 102 to the outside air. An intake side duct inlet 110a is provided on the lower surface (-Y surface) of the intake side duct 110. The intake side duct 110 is disposed so that the intake side duct inlet 110a is airtightly connected to the first intake port 105 and the second intake port 106. An intake side duct outlet 110b is provided on the rear surface (-Z surface) of the intake side duct 110, and the cooling fan 113 is attached to the intake side duct outlet 110b.
[0019] The cooling fan 113 is a so-called centrifugal fan that draws in air from an intake port 113a facing the intake duct outlet 110b and expels the drawn air from a side exhaust port 113b. The exhaust duct 112 has an exhaust duct inlet 112a and an exhaust duct outlet 112b. The exhaust duct 112 is arranged so that the exhaust duct inlet 112a is airtightly connected to the side exhaust port 113b of the cooling fan 113 and the exhaust duct outlet 112b is airtightly connected to the exhaust port 104.
[0020] Therefore, by driving the cooling fan 113, outside air (air) flows into the intake side duct 110 from the first intake port 105 and the second intake port 106. The air that flows into the intake side duct 110 passes through the cooling fan 113 and the exhaust side duct 112, and is discharged to the outside from the exhaust port 104. In this way, the air flowing inside the cooling duct is heated by heat generated in the heat-generating components inside the image capturing device 102 while passing through the inside of the image capturing device 102, and is discharged to the outside, thereby cooling the heat-generating components (in other words, a rise in temperature is suppressed).
[0021] Next, a method of heat transfer from the first media slot 114 and the second media slot 115 to the cooling duct will be described. Note that recording media is stored in the media slots, and the recording media generates heat as a result of signal processing on the recording media. Therefore, although the recording media stored in the media slot is the target for cooling by the cooling duct, the recording media is cooled via the media slot, so for convenience in the following description, expressions such as "the media slot is cooled" will be used.
[0022] Fig. 4 is an exploded perspective view showing a heat transfer configuration from the media slot to the intake duct 110. Fig. 4(a) is an exploded rear perspective view, and Fig. 4(b) is an exploded front perspective view.
[0023] The intake side duct 110 is disposed on the rear side (-Z side) of the media slot, and a heat transfer member 120 is attached to the rear side of the first media slot 114 to transfer heat from the first media slot 114 to the intake side duct 110. Also, on the front side (+Z surface) of the intake side duct 110, a substantially rectangular opening 110c is provided at a position that overlaps with the heat transfer member 120 when viewed from the optical axis direction (a position that overlaps with the heat transfer member 120 on the optical axis projection surface).
[0024] 5 is a perspective view of heat transfer member 120. Heat transfer member 120 has sheet-shaped (thin plate-shaped) base 121 and a plurality of fins 122 protruding from base 121. Base 121 is made of, for example, Poron (registered trademark), which is an elastic material. The plurality of fins 122 is made of, for example, a graphite sheet. The graphite sheet is wrapped around base 121 and is partially folded and overlapped to form the plurality of fins 122.
[0025] Fig. 6(a) is a bottom view showing the assembled state of the first media slot 114, the heat transfer member 120, and the intake side duct 110. Fig. 6(b) is a cross-sectional view taken along the line MA-MA in Fig. 6(a). Fig. 7(a) is a front view showing the assembled state of the first media slot 114, the heat transfer member 120, and the intake side duct 110. Fig. 7(b) is a cross-sectional view taken along the line MB-MB in Fig. 7(a).
[0026] The surface of the heat transfer member 120 on which the multiple fins 122 are not formed is adhered to the surface of the first media slot 114, but this is not limiting, and the surface may be pressed against the surface of the first media slot 114 when the control circuit board 111 and the cooling duct are assembled. The multiple fins 122 of the heat transfer member 120 protrude from the opening 110c toward the inside of the intake side duct 110.
[0027] 6(b) shows a dashed line frame indicating the outermost shape 125 of the heat transfer member 120 (base portion 121), and the outermost shape 125 of the heat transfer member 120 encompasses the outer periphery of the opening 110c of the intake side duct 110. Therefore, the outer periphery of the surface on which the multiple fins 122 are formed in the base portion 121 of the heat transfer member 120 is in pressure contact with the peripheral portion of the opening 110c on the surface on which the opening 110c is formed in the intake side duct 110. In other words, the outer periphery of the base portion 121 is sandwiched and compressed between the first media slot 114 and the intake side duct 110 in the Z direction, thereby blocking the opening 110c.
[0028] Here, an elastic material is used for base 121, and the graphite sheet surrounding base 121 is thin (has a small thickness). Therefore, even if a step occurs between base 121 and the graphite sheet forming multiple fins 122 as shown in FIG. 5, this step is absorbed by the deformation of base 121. As a result, no gap communicating with opening 110c occurs between heat transfer member 120 and intake duct 110. In other words, opening 110c is airtightly closed, and therefore dust or water droplets that have entered intake duct 110 by cooling fan 113 will not enter the inside of imaging device 102.
[0029] As described above, in the first embodiment, the first media slot 114 and the intake side duct 110 are thermally connected by the base portion 121 of the heat transfer member 120. In addition, by having a plurality of fins 122 protruding into the inside of the intake side duct 110, it becomes possible to efficiently dissipate heat to the air flowing inside the intake side duct 110.
[0030] Here, as shown in FIG. 6(b), a part of the area EA in which the intake duct entrance 110a of the intake duct 110 is extended in the +Y direction in the intake duct 110 overlaps with the media slot on the optical axis projection surface. In addition, inside the intake duct 110, air flows as shown by the arrow AF1 shown in FIG. 6(b) and the arrow AF2 shown in FIG. 7(b). Therefore, as shown in FIG. 6 and FIG. 7, the heat transfer member 120 has multiple fins 122 arranged approximately parallel to the flow of air in the area EA. In this way, heat can be efficiently transferred from the multiple fins 122 to the air flowing through the intake duct 110, thereby making it possible to cool the first media slot 114.
[0031] In the first embodiment, only the configuration for cooling the first media slot 114 is shown, but a similar cooling configuration can be applied to the second media slot 115. Also, one heat transfer member 120 may be arranged to straddle the first media slot 114 and the second media slot 115. In this case, there is a concern that the base portion 121 of the heat transfer member 120 may not be pressed against the intake side duct 110 in the vicinity of the gap between the first media slot 114 and the second media slot 115. To address this problem, for example, a filler for pressing the base portion 121 against the intake side duct 110 may be placed in the gap formed between the first media slot 114 and the second media slot 115. This can prevent air from leaking into the inside of the imaging device 102 from the opening 110c.
[0032] <Second embodiment> Fig. 8(a) is a simplified rear view of the imaging system 100A according to the second embodiment. Fig. 8(b) is a cross-sectional view taken along the line MC-MC shown in Fig. 8(a). Fig. 9 is a bottom view of the imaging system 100A. Fig. 9(b) is a cross-sectional view taken along the line MD-MD shown in Fig. 9(a).
[0033] The imaging system 100A includes an imaging device 102A and a lens barrel 103 provided in front of the imaging device 102A. The external configuration of the imaging device 102A is the same as that of the imaging device 102 according to the first embodiment, and the same components of the imaging device 102A as those of the imaging device 102 are denoted by the same reference numerals and will not be described.
[0034] As in the first embodiment, a first media slot 114 and a second media slot 115 are mounted on the control circuit board 111. As shown in Fig. 8(b) , in the second embodiment, at least one heat source heating element 401 is further mounted on the control circuit board 111. The heating element 401 is, for example, an element consuming a large amount of power, such as an image processing semiconductor (image processing engine) or an MPU.
[0035] Instead of the intake side duct 110 of the imaging system 100, the imaging system 100A includes an intake side duct 160. The configuration of the intake side duct 160 is the same as that of the intake side duct 110, except that it does not include the opening 110c and has a dividing rib 404.
[0036] In the imaging device 102A, the first media slot 114, the second media slot 115, and the heat generating element 401 are each in contact with the +Z surface of the intake duct 160 via a heat transfer member 402. The heat transfer member 402 is made of, for example, a heat dissipation rubber, and is in a state of being compressed with a constant force in the Z direction.
[0037] Therefore, heat generated in the first media slot 114, the second media slot 115, and the heat generating element 401 is transferred to the outer wall surface of the wall portion on the +Z side of the intake side duct 160 via the heat transfer member 402, and the intake side duct 160 is heated. Heat exchange occurs between the inner wall surface of the wall portion on the +Z side of the intake side duct 160 and the air flowing inside the intake side duct 110, and the heated air is released to the outside of the imaging system 100A. As a result, the first media slot 114, the second media slot 115, and the heat generating element 401 are cooled, and a rise in temperature is suppressed.
[0038] The imaging system 100A has a gripping part 216 that is a part where the user grips the imaging device 102A, and in the imaging system 100A, a part within an elliptical area EB indicated by a dashed line in Fig. 8(b) is the gripping part 216. Although not shown, operating members such as various buttons and switches for performing various settings and imaging operations of the imaging system 100A are arranged on the top surface and back surface of the gripping part 216. Therefore, the optical axis direction length (Z direction length) H of the gripping part 216 is determined in consideration of the balance between gripping ease and operability.
[0039] 8(b), in the imaging system 100A, the optical axis direction length of the portion of the intake side duct 160 included in the gripping portion 216 is made shorter than the optical axis direction length of the other portions, thereby suppressing an increase in the optical axis direction length H of the gripping portion 216. Conversely, in the intake side duct 160, by increasing the optical axis direction length of the portions other than the gripping portion 216, it is possible to increase the amount of air flowing through the intake side duct 160 and improve the heat dissipation efficiency.
[0040] The air flow in the intake duct 160 will be described in detail below. The flow path of the air (outside air) flowing into the intake duct 160 from the first intake port 105 and the second intake port 106 by the cooling fan 113 is divided by the dividing rib 404 as shown in Fig. 9(b). Therefore, the air flowing in from the first intake port 105 and the air flowing in from the second intake port 106 flow through separate flow paths, then merge near the intake duct outlet 110b and flow into the cooling fan 113, and then pass through the exhaust duct 112 and are discharged from the exhaust port 104.
[0041] At this time, the air flowing into the intake side duct 160 from the first intake port 105 flows through the media cooling flow path 405 (first flow path) formed by the dividing rib 404 as shown by the arrow AF3. This cools the first media slot 114 and the second media slot 115 arranged in series along the air flow in the media cooling flow path 405. On the other hand, the air flowing into the intake side duct 160 from the second intake port 106 flows through the element cooling flow path 406 (second flow path) formed by the dividing rib 404 as shown by the arrow AF4, and cools the heat generating element 401. With this configuration, the cooling efficiency of the first media slot 114, the second media slot 115, and the heat generating element 401 can be improved.
[0042] Generally, the power consumption of the heat generating element 401 such as an image processing semiconductor is larger than the power consumption of the recording media accommodated in the first media slot 114 and the second media slot 115. Therefore, it is desirable to make the air flow rate of the element cooling channel 406 larger than the air flow rate of the media cooling channel 405. In consideration of such a requirement, in the imaging system 100A, as shown in FIG. 9(a), the opening area of the second intake port 106 is larger than the opening area of the first intake port 105. In addition, in the imaging system 100A, as can be seen from FIG. 8(b) and FIG. 9(b), the element cooling channel 406 is provided in a portion of the intake side duct 160 that is longer in the optical axis direction.
[0043] As described above, in the second embodiment, the airflow paths for cooling the first media slot 114 and the second media slot 115 are separated from the airflow paths for cooling the heat generating element 401. This allows the recording media and the heat generating element 401 to be cooled efficiently. Also, the optical axis direction length of the intake duct 110 is shorter at the gripping portion 216 than at other portions. This makes it possible to ensure appropriate air flow rates in each of the media cooling flow path 405 and the element cooling flow path 406 while suppressing an increase in the optical axis direction length H of the gripping portion 216.
[0044] <Third embodiment> Fig. 10 is an external perspective view of an imaging system 100B according to a third embodiment. Fig. 10(a) is a front perspective view of the imaging system 100B, and Fig. 10(b) is a rear perspective view of the imaging system 100B. Note that among the components of the imaging system 100B, the same components as those of the imaging system 100 are denoted by the same reference numerals and will not be described.
[0045] The imaging system 100B includes an imaging device 102B and a lens barrel 103 provided in front of the imaging device 102B. On the top surface of the imaging device 102B, there are provided a power switch 211 for switching the power of the imaging device 102B on / off, a mode dial 212 for switching between a still image recording mode and a video recording mode, and a mode dial 213 for starting / stopping still image and video capture.
[0046] On the rear surface of the imaging device 102B, there are provided a display device 215 such as a liquid crystal display panel for displaying settings and status of the imaging device 102B, displaying a live view, displaying captured images, and the like, and a plurality of operation members 214 for setting the imaging device 102B and performing a capturing operation. In addition, an exhaust port 104 is provided on the right side surface of the imaging device 102B. On the left side of the imaging device 102B, a gripping portion 216 is provided, and an intake port 221 and a card cover 218 are provided on the gripping portion 216. The card cover 218 is a movable member that can transition between an open position that exposes the recording media insertion slot 107 (see FIG. 11) to the outside and a closed position that covers and conceals the recording media insertion slot 107.
[0047] FIG. 11 is a left side view of the imaging device 102B. The card cover 218 is not shown in FIG. 11, and therefore, the state in which the two recording media insertion openings 107 covered by the card cover 218 during normal use of the imaging system 100B are exposed is shown. The recording media insertion openings 107 are openings for inserting and removing the recording media 234 (see FIG. 12(b)) into and from the first media slot 114 and the second media slot 115. The first media slot 114 and the second media slot 115 are arranged side by side in the Y direction, which is the height direction of the imaging device 102B, on the grip part 216. By opening the card cover 218, the user can insert and remove the recording media 234 (see FIG. 12(b)) into and from the first media slot 114 and the second media slot 115 through the recording media insertion openings 107. The recording media 234 is, for example, a semiconductor memory card or the like.
[0048] Fig. 12 is a diagram showing the configuration of a cooling duct provided inside the imaging device 102B, Fig. 12(a) is a cross-sectional view taken along the arrow ME-ME shown in Fig. 11, and Fig. 12(b) is an enlarged view of an area EC shown by a dashed line in Fig. 12(a).
[0049] An imaging element 109, a control circuit board 111, a media board 231, and a cooling duct are arranged inside the imaging device 102B. The cooling duct in the third embodiment is composed of an intake duct 223, an intermediate duct 225a, a cooling fan 113, and an exhaust duct 225b.
[0050] Control circuit board 111 and media board 231 are electrically connected by connector 233. A rigid-flexible board (rigid FPC) is used for media board 231, and first media slot 114 and second media slot 115 are mounted on a rigid portion (hard portion 231a1 described later) of the rigid FPC. Note that media board 231 may be integrated with control circuit board 111.
[0051] In the area EC, a heat exchange section is formed for cooling the recording media 234 housed in the first media slot 114 and the second media slot 115 of the imaging device 102B.
[0052] As shown in FIG. 12(a), one end of the intake side duct 223 is airtightly connected to the intake port 221. As shown in FIG. 12(b), the +Z side wall surface of the intake side duct 223 and the second media slot 115 are thermally connected via a heat transfer member 402. The heat transfer member 402 may be made of, for example, heat dissipation rubber. The -Z side wall of the intake side duct 223 is formed by the hard part 231a2 constituting the media substrate 231. Although not shown in FIG. 12, the first media slot 114 is also thermally connected to the +Z side wall surface of the intake side duct 223 via the heat transfer member 402.
[0053] Heat generated by the recording media stored in the first media slot 114 and the second media slot 115 is transferred to the intake side duct 223 via the heat transfer member 402. The heat transferred to the intake side duct 223 is further transferred to the air flowing through the intake side duct 223, thereby cooling the recording media and suppressing a rise in temperature.
[0054] Here, we will explain the air flow in the intake side duct 223. Figure 13 is a cross-sectional view taken along the arrows MF-MF in Figure 12(a). The intake side duct 223 is made of a metal material with good thermal conductivity, such as magnesium, except for the portion formed by the hard part 231a2 (see Figure 12(b)).
[0055] The outside air that flows from the intake port 221 into the intake side duct 223 flows in the -X direction and then flows in the +Y direction. At this time, the intake side duct 223 is configured to be approximately U-shaped on the optical axis direction projection plane so that the air flows as shown by the arrow AF5 through the area ED that overlaps the first media slot 114 and the second media slot 115 on the projection plane viewed from the optical axis direction (Z direction). Also, as described above, the first media slot 114 and the second media slot 115 are each in thermal contact with the +Z side wall of the intake side duct 223 via the heat transfer member 402. Therefore, the air that flows in from the intake port 221 flows as shown by the arrow AF5 so as to make a U-turn inside the intake side duct 223, and at that time, heat exchange is performed with the first media slot 114 and then with the second media slot 115. In this way, it is possible to cool the first media slot 114 and the second media slot 115 with a single airflow.
[0056] The downstream opening of the intake side duct 223 is connected to the intake side opening of the flat intermediate duct 225a, and the air flow path from the intake side duct 223 to the intermediate duct 225a is formed approximately parallel to the X direction. A cooling fan 113 is attached to the intermediate duct 225a, and the intake side opening of the exhaust side duct 225b is airtightly connected to the exhaust port of the cooling fan 113, and the exhaust side opening of the exhaust side duct 225b is airtightly connected to the exhaust port 104. Therefore, when the cooling fan 113 is driven, air flows in the order of the intake side duct 223, the intermediate duct 225a, the cooling fan 113, and the exhaust side duct 225b, and the first media slot 114 and the second media slot 115 are forcibly air-cooled.
[0057] The arrangement of intake duct 223 (cooling duct) is subject to the following first and second constraints. The first constraint is that first media slot 114 and second media slot 115 are provided near the exterior on the -Z side of imaging device 102B so that recording media 234 can be easily inserted and removed when card cover 218 is opened. The second constraint is that a board on which operation member 214 is mounted needs to be placed on grip portion 216 on the back surface of imaging device 102B.
[0058] In response to such constraints, in the second embodiment, the -Z side wall of the intake side duct 223 is formed of a media substrate 231, thereby suppressing the thickness of the intake side duct 223 in the optical axis direction and enabling the mounting of the operation member 214. Also, by making the intake side duct 223 approximately U-shaped on the optical axis direction projection plane, it is possible to cool the first media slot 114 and the second media slot 115.
[0059] Next, we will explain the features of the media substrate 231 for improving the cooling efficiency of the first media slot 114 and the second media slot 115. Fig. 14(a) is a cross-sectional view taken along the arrow MG-MG shown in Fig. 12, and Fig. 14(b) is an enlarged view of region EF in Fig. 14(a).
[0060] Area EF shown in Fig. 14(a) corresponds to area EC shown in Fig. 12(a) and shows a heat exchange unit for cooling first media slot 114 and second media slot 115. Fig. 14(c) is a perspective view showing the arrangement of members constituting the heat exchange unit in area EF.
[0061] As described above, a rigid FPC is used for the media board 231, and the rigid parts 231a1 and 231a2 and the flexible part 231b connecting the rigid parts 231a1 and 231a2 are included. The rigid parts 231a1 and 231a2 have the same rigidity as a printed circuit board.
[0062] The first media slot 114 and the second media slot 115 are mounted on one surface of the rigid part 231a1. The rigid part 231a2 forms part of the wall of the intake duct 223 (see FIG. 12(b)). The flexible part 231b has flexibility (flexibility) and has a curved shape bent approximately 180 degrees into a U-shape so that the rigid parts 231a1 and 231a2 are arranged opposite each other in the optical axis direction.
[0063] Heat is transferred from the first media slot 114 and the second media slot 115 to the intake duct 223 via roughly two heat transfer paths.
[0064] As described above, the first heat transfer path is a heat transfer path from the first media slot 114 and the second media slot 115 to the intake side duct 223 via the heat transfer member 402.Since the first heat transfer path has already been explained, its explanation will be omitted here.
[0065] The second heat transfer path is a heat transfer path via a copper pattern provided on the media board 231. Heat generated in the recording medium 234 is transferred to the media board 231 on which the first media slot 114 and the second media slot 115 are mounted. In the media board 231, the heat is transferred in the order of the hard part 231a1, the flexible part 231b, and the hard part 231a2 via the copper pattern, as shown by the arrow AT1 in Fig. 14(b). Since the hard part 231a2 constitutes the wall surface of the intake side duct 223, heat exchange takes place between the hard part 231a2 and the air flowing through the intake side duct 223.
[0066] In this way, in the imaging device 102, heat is transferred from the -Z side surfaces of the first media slot 114 and the second media slot 115 to the intake side duct 223 via the heat transfer member 402. Also, heat is transferred from the +Z side surfaces of the first media slot 114 and the second media slot 115 to the intake side duct 223 via the rigid portion 231a1, the flexible portion 231b, and the rigid portion 231a2. In this way, heat can be efficiently transferred from the first media slot 114 and the second media slot 115 to the intake side duct 223, and the heat can be exhausted to the air flowing through the intake side duct 223.
[0067] In addition, from the viewpoint of increasing the heat transfer efficiency in the second heat transfer path, it is preferable to provide a continuous copper pattern in the region other than the circuit of the hard part 231a and the flexible part 231b. In this case, by forming a copper pattern from the -Z side surface of the hard part 231a1 through the flexible part 231b to the +Z side surface of the hard part 231a2, it is possible to efficiently perform heat exchange between the hard part 231a2 and the air flowing through the intake side duct 223. In addition, a plurality of fins (not shown) for heat dissipation may be arranged on the +Z side surface of the hard part 231a2, that is, on the surface forming the inner wall of the intake side duct 223. This makes it possible to more efficiently perform heat exchange between the hard part 231a2 and the air flowing through the intake side duct 223.
[0068] Incidentally, in order to convert the operation of the operating member 214 into an electrical signal, a board on which a switch is mounted is required inside the operating member 214. As described above, by mounting the switch of the operating member 214 on the rigid portion 231a2 of the media board 231 and forming one side surface of the intake side duct 223, it is possible to shorten the length of the grip portion 216 in the optical axis direction.
[0069] Next, a modified example of the structure of the region EF (see FIG. 14), that is, a modified example of the heat exchange section, will be described. FIG. 15 is a perspective view illustrating the configuration of a media substrate 232, which is a modified example of the media substrate 231, and the heat transfer path from the media substrate 232.
[0070] The media board 232 is composed of rigid parts 232a1, 232a2, 232a3 and flexible parts 232b1, 232b2. The rigid part 232a1 is equipped with the first media slot 114 and the second media slot 115. The rigid parts 232a2, 232a3 are connected airtight in the Y direction and form the -Z side wall of the intake duct 223. The flexible part 232b1 connects the rigid parts 232a1, 232a2 in a state of being curved in an approximately U-shape on the +Y side of the rigid parts 232a1, 232a2. Similarly, the flexible part 232b2 connects the rigid parts 232a1, 232a3 in a state of being curved in an approximately U-shape on the -Y side of the rigid parts 232a1, 232a3.
[0071] Heat is transferred from the first media slot 114 and the second media slot 115 to the intake duct 223 via the heat transfer member 402 through the first heat transfer path described with reference to Fig. 14. Also, in areas of the rigid parts 232a1, 232a2, 232a3 and the flexible parts 232b1, 232b2 other than the circuits, a copper pattern (not shown) is preferably arranged, similarly to the media substrate 231.
[0072] With the above configuration, media substrate 232 has a heat transfer path indicated by arrow AT2 in addition to the heat transfer path indicated by arrow AT1 corresponding to the second heat transfer path of media substrate 231. Therefore, when media substrate 232 is used, it is possible to more effectively dissipate heat generated in first media slot 114 to intake duct 223 compared to when media substrate 231 is used.
[0073] As described above, in the third embodiment, heat is dissipated from the first media slot 114 and the second media slot 115 mounted on the media substrates 231, 232 to the intake side duct 223 via the heat transfer member 402. In addition, by using a rigid FPC having multiple hard parts and at least one flexible part as the media substrates 231, 232 and forming the wall of the intake side duct 223 with the hard parts, heat is dissipated from the hard parts to the intake side duct 223 via the flexible parts. With this configuration, it is possible to efficiently dissipate heat from the first media slot 114 and the second media slot 115 to the intake side duct 223.
[0074] In the above description, the configuration of the imaging device main body having two media slots has been described, but the number of media slots may be one or more than three. When there are three or more media slots, a flow path may be formed so that air flows sequentially through the areas in the intake duct 223 where the three media slots are thermally connected to each other.
[0075] <Fourth embodiment> In the fourth embodiment, a configuration in which the battery storage section is used to cool the media slot will be described. Fig. 16 is an external perspective view showing an image capture system 100C as viewed from the bottom side. The image capture system 100C is composed of an image capture device 102C, a lens barrel 103, and an external cooling module 600. Compared to the image capture device 102 described in the first embodiment, the image capture device 102C differs in that it does not include a second intake port 106, but the other configurations are the same as those of the image capture device 102.
[0076] The grip 216 of the imaging system 100C is provided with a battery storage section 700. The battery storage section 700 stores a battery (not shown). A removable battery cover (not shown) is provided in the battery storage section 700, but the battery cover is not shown in FIG.
[0077] The battery storage section 700 is provided with an electrical contact 710. When a battery (not shown) is stored in the battery storage section 700, the terminal of the battery comes into contact with the electrical contact 710, whereby power is supplied from the battery to the imaging system 100.
[0078] Inside the grip 216 of the imaging device 102C, a first media slot 114 and a second media slot 115 are arranged adjacent to the battery storage section 700. As in the first embodiment, the user can insert and remove a recording medium (not shown) through a recording media insertion slot 107 provided on the left side surface of the imaging device 102C.
[0079] 17A and 17B are external perspective views of an external cooling module 600 (hereinafter referred to as the "cooling module 600") that is detachable from the imaging device 102C. Fig. 17A is a rear perspective view of the cooling module 600, and Fig. 17B is a front perspective view of the cooling module 600.
[0080] The cooling module 600 has an intake port 606, an exhaust port 605, a cooling fan 607, a partition plate 608, and an electrical contact 609. A battery (not shown) is also attached to the cooling module 600, and power can be supplied from the electrical contact 609 to the image capture device 102C.
[0081] Fig. 18 is a perspective view of the appearance of an imaging system 1000 configured by mounting a cooling module 600 on an imaging system 100C. Fig. 18(a) is a rear perspective view of the imaging system 1000, and Fig. 18(b) is a front perspective view of the imaging system 1000.
[0082] The cooling module 600 is usually used for the purpose of enhancing the cooling function of a cooling duct provided in the image capture device 102C. Therefore, as shown in Fig. 19(b) later, the length in the optical axis direction of the part of the cooling module 600 that is disposed on the lower side (-Y side) of the grip part 216 of the image capture device 102C is set to a length that does not block the first intake port 105.
[0083] When the cooling module 600 is attached to the imaging device 102 described in the first embodiment, the second air intake 106 provided in the imaging device 102 is blocked by the cooling module 600. Therefore, in order to make it possible to attach the cooling module 600 to the imaging device 102, it is necessary to take measures such as providing a ventilation path communicating with the second air intake 106 or changing the shape of the second air intake 106 so as not to block it.
[0084] Furthermore, the mechanism for holding the cooling module 600 in the mounted state relative to the image capture device 102C is not particularly limited. For example, the cooling module 600 may be held by friction between the partition plate 608 and the wall surface of the battery storage section 700 (press-fitting), or a tripod base having a female thread may be provided on the bottom surface of the image capture device 102C, and the cooling module 600 may be provided with a male thread that screws into the tripod base.
[0085] Fig. 19 is a diagram for explaining a configuration for cooling various heat generating elements in the imaging system 100. Fig. 19(a) is a front view of the imaging system 1000, Fig. 19(b) is a cross-sectional view taken along the arrows KA-KA shown in Fig. 19(a), and Fig. 19(c) is a cross-sectional view taken along the arrows KB-KB shown in Fig. 19(a).
[0086] 19(b), when the cooling module 600 is attached to the imaging device 102, the partition plate 608 is inserted into the battery storage section 700 and the electrical contacts 609 come into contact with electrical contacts 710 provided in the battery storage section 700. This allows power to be supplied to the imaging device 102 from a battery (not shown) stored in the cooling module 600. The internal space of the battery storage section 700 is divided by the partition plate 608 into a -Z side space 700a and a +Z side space 700b in a state of communication on the +Y side.
[0087] When cooling fan 607 of cooling module 600 is driven, outside air flows into -Z side space 700a from intake port 606. The air thus flowing into space 700a flows in this order through -Z side space 700a, the +Y side communication passage, and +Z side space 700b, as shown by arrow FA8, and is then exhausted from exhaust port 605.
[0088] The control circuit board 111 on which the first media slot 114 and the second media slot 115 are mounted is disposed so as to be close to or in contact with the -Z side wall surface of the battery housing section 700. Thus, heat is transferred from the first media slot 114 and the second media slot 115 to the air flowing through the -Z side space 700a via the control circuit board 111 and the -Z side wall surface of the battery housing section 700. In this way, the first media slot 114 and the second media slot 115 are cooled, and the heated air is discharged from the exhaust port 605.
[0089] In the fourth embodiment, in addition to cooling the media slot described above, various heat generating elements mounted on the imaging device 102C are cooled using the battery housing section 700. Specifically, as shown in Fig. 19(c), heat generated by the imaging element 109 is transferred by the heat transfer member 611 to the wall surface on the +X side of the battery housing section 700, and is transferred from the wall surface on the +X side of the battery housing section 700 to the air flowing inside the battery housing section 700. This allows the imaging element 109 to be cooled. Note that the heat transfer member 611 may be configured to transfer heat generated by heat generating elements other than the imaging element 109.
[0090] 19(b) and (c), a heat transfer member 613 is disposed inside the gripping part 216 so as to be adjacent to a wall surface on the +Z side of the battery storage part 700. By configuring the heat generated by a heat generating element (not shown) provided inside the imaging device 102 to be transferred to the heat transfer member 613, the heat can be transferred from the wall surface on the +Z side of the battery storage part 700 to the air flowing inside the battery storage part 700, thereby cooling the heat generating element.
[0091] 19(c), a cutout 614 may be provided on the surface of the battery housing 700 on which the heat transfer members 611, 613 are arranged, so that a part of the heat transfer members 611, 613 is exposed to the space of the battery housing 700. This improves the efficiency of heat transfer from the heat transfer members 611, 613 to the air flowing inside the battery housing 700, making it possible to more effectively cool the imaging element 109 and the heat generating element. In the above description, the cooling module 600 is attached to the imaging device 102C, but the cooling module 600 can also be attached to the imaging device 102B according to the third embodiment.
