Description

[Technical field]

[0001] The present invention relates to an imaging device and an electronic device. [Background technology]

[0002] There is a demand for higher image quality for recorded video. In order to meet such needs, when attempting to achieve higher image quality by increasing the resolution and frame rate, the amount of power consumed 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 lose performance when they become too hot, it is necessary to provide a structure for cooling these inside the imaging device. Thus, an imaging device has been proposed that is primarily intended for video shooting (i.e., recording video) and has a structure for cooling the recording media (see, for example, Patent Document 1). [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] The imaging device described in the above Patent Document 1 is equipped with multiple ducts to cool multiple heat sources, including a media board on which a media slot for storing recording media is mounted, which inevitably makes the imaging device larger. In addition, since the media board and the cooling ducts are thermally connected, the recording media is cooled via the media board and the media slot. Therefore, it cannot be said that the cooling efficiency of the recording media is high.

[0005] An object of the present invention is to provide an imaging device that is capable of efficiently cooling a recording medium while avoiding an increase in size. [Means for solving the problem]

[0006] The imaging device of the present invention is an imaging device comprising an imaging element, a media board having a media slot for storing recording media, a cooling duct containing an air-cooling fan, and a heat conductive member attached to the cooling duct and thermally connecting the recording media stored in the media slot to the cooling duct, wherein the heat conductive member is capable of transitioning between a state in contact with the recording media stored in the media slot and a state away from the recording media. Effect of the Invention

[0007] According to the present invention, it is possible to realize an imaging device that is capable of efficiently cooling a recording medium while avoiding an increase in size. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1(a) is an exploded perspective view of an imaging system 1 according to an embodiment. The imaging system 1 is composed of an imaging device 2 and a lens barrel 3 that is detachable from the imaging device 2. Fig. 1(b) is a rear perspective view of the imaging device 2.

[0010] For convenience of explanation, an XYZ Cartesian coordinate system is defined for the imaging system 1 as shown in FIG. 1. As shown in FIG. 1, the Z direction is the front-rear direction of the imaging device 2, the Y direction is the height direction of the imaging device 2, and the X direction is the width direction of the imaging device 2. The Z direction is parallel to the optical axis of the lens barrel 3 and perpendicular to the imaging surface of the imaging element 201 (see FIG. 2), and the direction from the imaging system 1 toward the subject (not shown) (the direction from the back side to the front side of the imaging system 1) is defined as the positive direction (+Z). Regarding the X direction, the direction from left to right when the imaging system 1 is viewed from the +Z side 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 2 is defined as the positive direction (+Y).

[0011] An annular mount 101 provided on the front surface of the imaging device 2 enables attachment and detachment of the lens barrel 3 by a known bayonet system. The imaging device 2 and the lens barrel 3 may be integrally configured and inseparably connected.

[0012] A convex portion 121 protruding toward the +Z side is provided on the -X side of the imaging device 2. The convex portion 121 is used as a gripping portion that is held by the user with the right hand when using the imaging system 1. The convex portion 121 is provided with a storage section (hereinafter referred to as a "battery storage section") for the battery 107 (see FIG. 4).

[0013] An intake port 113 is provided on the rear surface of the imaging device 2, an exhaust port 116 is provided on the +X side surface of the imaging device 2, and a media cover 125 that can be opened and closed by a rotating motion is provided on the top surface of the imaging device 2. As shown in FIG. 1(b), when the media cover 125 is operated to the open position, a media insertion / removal opening 126 and an engagement portion 166 are exposed to the outside. By operating the media cover 125 to the open position, a user can insert and remove a recording medium 129 through the media insertion / removal opening 126 into a first media slot 146 and a second media slot 147 (see FIG. 2(b)) provided inside the imaging device 2. The engagement portion 166 is a portion for holding the media cover 125 in the closed position, and its details will be described later with reference to FIG. 9.

[0014] FIG. 2 is an exploded perspective view of the imaging device 2, with FIG. 2(a) being a front perspective view and FIG. 2(b) being a rear perspective view. Note that in FIG. 2, components that are not related to the present invention are omitted from the illustration. From the front side to the rear side of the imaging device 2, a front base member 127, an imaging unit 200, a control board 104, and a cooling duct 108 are arranged. On the rear side of the cooling duct 108, a media board 148 on which a first media slot 146 and a second media slot 147 are mounted is arranged. Note that in the following description, when there is no need to distinguish between the first media slot 146 and the second media slot 147, they may be simply referred to as "media slots" as appropriate.

[0015] The imaging device 2 includes a rear base member (not shown) on the rear side (-Z side) that constitutes the housing of the imaging device 2 together with the front base member 127. The media cover 125 is rotatably held by the rear base member. The media board 148 is also held by the rear base member and is not in contact with the rear side (-Z side surface) of the cooling duct 108 (see FIG. 9).

[0016] Fig. 3 is an exploded perspective view of the structure from the control board 104 to the media slots, with Fig. 3(a) being a rear perspective view and Fig. 3(b) being a front perspective view. The cooling duct 108 is generally composed of a duct case 109 and an air-cooled fan 110. The duct case 109 is composed of a first case member 130 that mainly forms the front and top and bottom surfaces of the cooling duct 108, and a second case member 133 that mainly forms the back surface of the cooling duct 108.

[0017] 3, the cooling duct 108 has a small length in the Z direction and a generally flat rectangular parallelepiped shape when viewed from the Z direction. In the imaging device 2, the cooling duct 108 is configured in such a generally flat plate shape, thereby preventing the cooling duct 108 from becoming large in size in the Z direction.

[0018] A plurality of airflow adjustment plates 131 are provided substantially parallel to the X direction on a surface of the first case member 130 that faces the inside of the cooling duct 108 (the front air passage side). Similarly, a plurality of airflow adjustment plates 134 are provided substantially parallel to the X direction on a surface of the second case member 133 that faces the inside of the cooling duct 108 (the rear air passage side). Note that the airflow adjustment plates 131 and 134, which will be described in detail later, play a role in determining the direction in which air flows in the front and rear air passages of the cooling duct 108, and also function as heat dissipation fins that increase the heat dissipation efficiency for the air flowing in the front and rear air passages.

[0019] The air-cooled fan 110 is fixed to a fastening portion 136 provided on the first case member 130, and is contained within the cooling duct 108. The air-cooled fan 110 is a double-suction centrifugal fan that takes in air from both the +Z side and the -Z side.

[0020] An element group 128 is mounted on the rear surface (-Z side surface) of the control board 104. The element group 128 includes heat generating elements that generate heat by performing various operations, such as an MPU that performs overall control of the imaging system 1. A heat dissipation rubber 139 with high thermal conductivity is sandwiched between the front surface (+Z side surface) of the cooling duct 108 and the element group 128. Note that, although only one element group 128 including heat generating elements is shown here, when there are multiple element groups 128 including heat generating elements, the element groups 128 are individually thermally connected to the front surface of the cooling duct 108 via the heat dissipation rubber 139.

[0021] Two elastic heat conductive members 141 are attached to the rear surface (-Z side surface) of the cooling duct 108. A media substrate 148 is disposed on the rear surface side of the cooling duct 108 so as not to come into contact with the elastic heat conductive members 141. A first media slot 146 and a second media slot 147 are mounted on the media substrate 148. The media slots are members that enable the recording medium 129 to be mounted on the media substrate 148. Although details will be described later, the elastic heat conductive members 141 come into contact with the recording medium 129 housed in the media slots when the media cover 125 is in the closed position, and are spaced apart from the recording medium 129 housed in the media slots when the media cover 125 is in the open position.

[0022] Next, a description will be given of heat generated inside the imaging device 2 and the air flow inside the cooling duct 108. Fig. 4 is a cross-sectional view showing a schematic configuration on a plane including the optical axis A of the imaging system 1 and perpendicular to the Y direction. Note that in Fig. 4, hatching is omitted for some cross sections, and the sizes of some components are exaggerated.

[0023] Light incident on the lens barrel 3 forms an image on the image sensor 201. The image sensor 201 converts the optical image into an image signal consisting of an electrical signal by photoelectric conversion and outputs the image signal. The image signal output from the image sensor 201 is transferred via the flexible substrate 202 to the element group 128 mounted on the control substrate 104 arranged on the rear side (-Z side) of the imaging unit 200. The element group 128 includes various semiconductor elements that perform overall control of the imaging system 1 and image processing, and the element group 128 converts the transferred image signal into image data consisting of a digital signal, and further performs predetermined image processing to generate image data for recording or image data for display.

[0024] Captured image information, including information such as setting values ​​in the imaging system 1 at the time of shooting and image data for recording and display, is saved (stored) in a recording medium 129 housed in a media slot. The recording medium 129 is, for example, a portable SD card or a CFexpress card. In the imaging system 1, it is possible to select a mode in which captured image information is recorded in only one of the two recording media 129 housed in the first media slot 146 and the second media slot 147, respectively, and a mode in which the same captured image information is recorded in both.

[0025] A battery 107 is stored in a battery storage section provided in the convex portion 121. The battery 107 supplies the imaging element 201, the element group 128, the first media slot 146, and the second media slot 147 with power required for their operation.

[0026] As described above, the imaging element 201 and the element group 128 generate heat as a result of their respective operations. Furthermore, the recording medium 129 generates heat as a result of operations such as writing captured image information to the recording medium 129 in the first media slot 146 and the second media slot 147. The heat generated inside the imaging device 2 is transferred to the cooling duct 108, as described below, and is further transferred to the air flowing inside the cooling duct 108, and is released to the outside air (outside the imaging system 1).

[0027] Specifically, inside the cooling duct 108, a front air passage 111 (first air passage) and a rear air passage 112 (second air passage) are formed to sandwich the air-cooled fan 110 in the Z direction. Openings are formed on a pair of end faces in the X direction of the cooling duct 108, and the opening on one of the -X side faces is airtightly connected to the air intake port 113, and the opening on the other +X side face is also a fan exhaust port for the air-cooled fan 110 and is airtightly connected to the exhaust port 116. The air-cooled fan 110 housed inside the cooling duct 108 has openings for intake (hereinafter referred to as "fan intake ports") on each of a pair of faces (the front face (the +Z side face) and the rear face (the -Z side face)) perpendicular to the optical axis direction.

[0028] When the air-cooled fan 110 is driven, the air that flows into the cooling duct 108 from the intake port 113 is guided to a front air passage 111 between the first case member 130 and the front surface of the air-cooled fan 110. The air flowing through the front air passage 111 flows into the inside of the air-cooled fan 110 from a fan intake port (first fan intake port) on the front surface of the air-cooled fan 110, and is then discharged from the exhaust port 116. This route is a first air passage AF1 shown by a dashed line. The air that flows into the cooling duct 108 from the intake port 113 is guided to a rear air passage 112 between the second case member 133 and the rear surface of the air-cooled fan 110. The air flowing through the rear air passage 112 flows into the inside of the air-cooled fan 110 from a fan intake port (second fan intake port) on the rear surface of the air-cooled fan 110, and is then discharged from the exhaust port 116. This route is the second air passage AF2 indicated by the dashed line.

[0029] Next, the air flow (first air passage AF1, second air passage AF2) inside cooling duct 108 will be described in more detail. Fig. 5 is a cross-sectional view taken along arrow BB in Fig. 4. As shown in Fig. 5, air intake port 113 is divided in the Y direction into a first air intake area 113a in the center and two second air intake areas 113b on the +Y side and -Y side of first air intake area 113a.

[0030] 3, airflow adjustment plates 134 are provided on the inner surface of the second case member 133 at a predetermined interval in the Y direction and approximately parallel to the X direction. When viewed from the Z direction, the first air intake area 113a is at approximately the same height in the Y direction as the fan intake port 110a on the rear surface of the air-cooled fan 110. Therefore, the air that flows from the first air intake area 113a into the rear air passage 112 is guided by the airflow adjustment plate 134 and travels in the +X direction, and then flows into the inside of the air-cooled fan 110 mainly from the -X side of the fan intake port 110a on the rear surface of the air-cooled fan 110. This airflow makes it possible to efficiently cool the recording media 129 stored in the second media slot 147, which is particularly located on the -X side of the two media slots.

[0031] The second air intake area 113b is located on the +Y side and -Y side of the first air intake area 113a. The +X end of the air flow adjustment plate 134 is not in contact with the +X side inner wall of the second case member 133. Therefore, the air that flows from the second air intake area 113b into the rear air passage 112 is guided by the air flow adjustment plate 134 to the +X side wall surface of the rear air passage 112 or its vicinity, and then reverses in the -X direction. The reversed air flow thus generated flows into the inside of the air-cooled fan 110 mainly from the +X side of the fan intake port 110a. At that time, the reversed air flow can efficiently cool the recording media 129 stored in the first media slot 146, which is located on the +X side of the two media slots.

[0032] The air flow in the front air passage 111 is similar to the air flow in the rear air passage 112. Fig. 4 shows, for convenience, a configuration in which two element groups 128 are arranged in the X direction as an example in which a cooling effect similar to the cooling effect caused by the air flow in the rear air passage 112 described above can be obtained. On the other hand, in a configuration in which heat is conducted from the control board 104 to the front surface of the cooling duct 108 (first case member 130) from one point in the element group 128 as shown in Fig. 3, it is not necessarily necessary to generate the above-mentioned reverse airflow in the front air passage 111.

[0033] With the above configuration, heat generated in the element group 128 is transferred to the front surface of the cooling duct 108 via the heat dissipation rubber 139, and is then transferred to the air flowing through the front air passage 111, and is released to the outside (outside air) of the image capture device 2. The elastic heat conductive member 141 is in contact with the recording media 129. The contact mechanism will be described in detail later. Heat generated in the recording media 129 housed in each of the two media slots is transferred to the rear surface of the cooling duct 108 via the two elastic heat conductive members 141, and is then transferred to the air flowing through the rear air passage 112, and is released to the outside (outside air) of the image capture device 2. In this way, it is possible to efficiently release heat generated inside the image capture device 2 to the outside air.

[0034] 6(a) is a perspective view of cooling duct 108 with elastic heat conductive member 141 attached. Duct air inlet 137 is formed on the -X side surface of cooling duct 108, and duct air inlet 137 is airtightly connected to air inlet 113.

[0035] Elastic heat conductive member 141 has base 143 including fixing portion 142 fixed to the back surface of second case member 133 constituting cooling duct 108, and protrusion 144 formed integrally with base 143 and protruding to the -Z side. The Z direction position of protrusion 144 changes when end 145 on the +Y side of protrusion 144 is pressed by media cover 125, as described below.

[0036] 6(b) is a schematic diagram showing the configuration of the first media slot 146 and the second media slot 147, and how the recording media 129 is inserted into and removed from the media slots. The first media slot 146 and the second media slot 147 each store recording media 129 of the same shape. However, this is not limited to the configuration, and the first media slot 146 and the second media slot 147 may each store recording media of different shapes or standards.

[0037] A first media slot 146 and a second media slot 147 are mounted on the media substrate 148, and openings 149, 150 are formed in areas facing the protrusion 144 of the elastic heat conductive member 141 in the optical axis direction (Z direction). In other words, when viewed from the optical axis direction, the entire area of ​​the openings 149, 150 is included in the area of ​​the recording medium 129 stored in the media slot, and the entire area of ​​the protrusion 144 is included in the entire area of ​​the openings 149, 150. As will be described in detail later, when the media cover 125 is closed, the protrusion 144 of the elastic heat conductive member 141 enters the openings 149, 150 and is in contact with the recording medium 129, and heat is directly transferred from the recording medium 129 to the elastic heat conductive member 141.

[0038] 7(a) is an exploded perspective view of the media cover 125. The media cover 125 is composed of a rotating cover 152, a sliding cover 153, a sliding cover holding member 154, and a biasing member 155. The sliding cover holding member 154 is fixed to the sliding cover 153 with a screw, with the rotating cover 152 sandwiched between the sliding cover holding member 154 and the sliding cover 153. The biasing member 155 is fixed to the rotating cover 152 with a screw, with the sliding cover holding member 154 sandwiched between the biasing member 155 and the rotating cover 152. In this way, the sliding cover 153 and the sliding cover holding member 154 are held slidably together with respect to the rotating cover 152 and the biasing member 155, the details of which will be described later with reference to FIG. 8.

[0039] Fig. 7(b) is a perspective view of the rotating cover 152. Fig. 7(c) is a perspective view of the slide cover 153. Fig. 7(d) is a perspective view of the slide cover holding member 154. Fig. 7(e) is a perspective view of the biasing member 155.

[0040] The rotating lid 152 is a sheet metal member and has appropriate elasticity. The rotating lid 152 has a rotating shaft 156, a sliding portion 157, an arm portion 158, and a convex portion 159. Both ends of the rotating shaft 156 are held by the housing of the imaging device 2, whereby the media cover 125 is held rotatably relative to the housing of the imaging device 2. The sliding cover 153 is a resin member and has a sliding portion 160, a first recess 161, a second recess 162, and an engagement portion 163. The sliding cover holding member 154 is a resin member and has a sliding portion 164. The biasing member 155 has a convex portion 165.

[0041] Fig. 8 is a perspective view illustrating the sliding action of media cover 125. Fig. 8(a) shows the state of media cover 125 in the closed position that covers media insertion / removal slot 126. When media cover 125 is in the closed position, slide cover 153 and slide cover holding member 154 are in a state in which convex portion 159 of rotating lid 152 engages with first concave portion 161 (see Fig. 7(c)) of slide cover 153. The state of media cover 125 shown in Fig. 8(a) is referred to as the "storage state."

[0042] FIG. 8(b) shows a state in which the slide cover 153 and the slide cover holding member 154 are pulled out relative to the rotating cover 152 in order to transition the media cover 125 from the closed position to the open position. The slide cover 153 and the slide cover holding member 154 are capable of sliding integrally with the rotating cover 152 within a predetermined range in a direction perpendicular to both the direction in which the slide cover 153 is attached and the X direction. When the media cover 125 is in the pulled out state, the slide cover 153 and the slide cover holding member 154 are in a state in which the convex portion 159 of the rotating cover 152 is engaged with the second concave portion 162 of the slide cover 153 (see FIG. 7(c)). The state of the media cover 125 shown in FIG. 8(b) is referred to as the "pulled out state."

[0043] FIG. 9 is a diagram for explaining the opening and closing operation of the media cover 125 and the heat conduction from the recording medium 129 to the elastic heat conductive member 141. FIG. 9(a) is a top view of the imaging system 1 when the media cover 125 is in the closed position and in the stored state, and FIG. 9(b) is a cross-sectional view along the arrow CC shown in FIG. 9(a). FIG. 9(c) is a top view of the imaging system 1 in a state in which the media cover 125 has been transitioned from the state of FIG. 9(a) to the drawn-out state, and FIG. 9(d) is a cross-sectional view along the arrow DD shown in FIG. 9(c). FIG. 9(e) is a top view of the imaging system 1 in a state in which the media cover 125 has been transitioned from the state of FIG. 9(c) to the open position by rotating approximately 90° around the rotation shaft 156, and FIG. 9(f) is a cross-sectional view along the arrow EE shown in FIG. 9(e).

[0044] 9(a) and (b), the media cover 125 is in a stored state, and the engagement portion 163 of the slide cover 153 engages with the engagement portion 166 provided on the rear base member, thereby holding the media cover 125 in the closed position.

[0045] When the media cover 125 is held in the closed position, the convex portion 165 of the biasing member 155, which rotates integrally with the rotating cover 152, comes into contact with the end portion 145 on the +Y side of the protrusion 144 of the elastic heat conducting member 141, and the protrusion 144 protrudes to the -Z side through the openings 149, 150. This causes the protrusion 144 to come into contact with the recording medium 129 stored in the media slot. In this way, it is possible to transmit heat generated by the recording medium 129 to the cooling duct 108 via the elastic heat conducting member 141. Note that by forming the biasing member 155 from a material with low thermal conductivity such as resin, it is possible to suppress a rise in temperature of the media cover 125 even if the protrusion 165 is in contact with the elastic heat conducting member 141.

[0046] When slide cover 153 and slide cover holding member 154 are slid toward the -Z side from the state shown in Fig. 9(a), engagement portion 163 and engagement portion 166 are disengaged, and media cover 125 enters the state shown in Fig. 9(c). In the states shown in Figs. 9(c) and (d), media cover 125 is in the pulled-out state, but media insertion / removal opening 126 is hidden by media cover 125.

[0047] When the media cover 125 is rotated from the state shown in Fig. 9(c), the media cover 125 transitions to the open position, and assumes the state shown in Fig. 9(e) and (f), in which the recording medium 129 can be inserted and removed from the media slot. In this way, the media cover 125 can transition between the closed position shown in Fig. 9(a) and the open position shown in Fig. 9(e), and conversely, the media cover 125 can be returned to the closed position by operating the media cover 125 in the order of Fig. 9(e), Fig. 9(c), and Fig. 9(a).

[0048] 9(e) and (f), the convex portion 165 of the biasing member 155 is spaced apart from the end portion 145 on the +Y side of the protrusion portion 144 of the elastic heat conductive member 141. Therefore, the protrusion portion 144 of the elastic heat conductive member 141 retracts to the +Z side, and the protrusion portion 144 is spaced apart from the recording medium 129. Therefore, even if the recording medium 129 is inserted or removed from the media slot in the state of FIG. 9(e) and (f), the recording medium 129 will not be damaged by the protrusion portion 144. For example, in the recording medium 129, as shown in FIG. 9(f), a plurality of contact portions 167 for communicating with the imaging device 2 may be exposed to the outside, but the contact portions 167 will not be damaged by the protrusion portion 144.

[0049] As described above, in the imaging device 2, the heat-generating element group 128 provided inside the imaging device 2 is thermally connected to the air-cooled fan 110 via the heat dissipation rubber 139. Also, instead of the media slot being thermally connected to the cooling duct as in the conventional case, the recording medium 129 housed in the media slot is thermally directly connected to the cooling duct 108 via the elastic heat conductive member 141. In this way, it is possible to cool the element group 128 and the recording medium 129 while preventing the imaging device 2 from becoming larger, and in particular, it is possible to cool the recording medium 129 more efficiently than in the past.
