[0027] An example of an embodiment of the present invention will be described below with reference to the drawings. Note that in this embodiment, the terms "upward," "downward," "leftward," "rightward," "forward," and "rearward" are used, but these directions are relative directions set for the imaging device shown in each drawing for the sake of convenience.

[0028] <Imaging device according to an embodiment> Fig. 1 is a simplified perspective view showing an example of an imaging device 100 according to this embodiment, as seen from the left front. Fig. 2 is a simplified perspective view of the imaging device 100 shown in Fig. 1, as seen from the right front. Examples of imaging devices include digital cameras and single-lens reflex cameras capable of capturing video. As shown in Figs. 1 and 2, the imaging device 100 includes a housing 110 that constitutes the main body of the imaging device 100, and a lens 120 attached to the housing 110.

[0029] The housing 110 is formed in a substantially cubic shape. A first intake section 110a is provided at the lower left end of the housing 110. Furthermore, a second intake section 110b is provided at the lower right end of the housing 110. The first intake section 110a and the second intake section 110b are openings that can take in air from outside the housing 110 into the housing 110. The first intake section 110a and the second intake section 110b are configured with, for example, a plurality of slit-shaped openings.

[0030] Furthermore, an exhaust section 110c is provided at the upper right end of the housing 110. The exhaust section 110c is an opening that can expel air inside the housing 110 to the outside of the housing 110. The exhaust section 110c is configured with, for example, a plurality of slit-shaped openings.

[0031] The opening that constitutes the exhaust section 110c is formed, for example, from the upper wall to the right side wall of the housing 110. Although not shown in the figure, the opening that constitutes the first intake section 110a is formed from the left side wall to the bottom wall, and the opening that constitutes the second intake section 110b is formed from the right side wall to the bottom wall.

[0032] A cover 119 for a recording unit 112 (described later in FIG. 5) into which a recording medium is inserted is provided at the bottom of the left side wall of the housing 110. Image data captured by the imaging device 100 is recorded on the recording medium.

[0033] The lens 120 is attached to the front side (front surface) of the housing 110. The lens 120 is replaceable. The lens 120 includes at least an imaging lens such as a focus lens or a zoom lens.

[0034] FIG. 3 is a diagram illustrating an example of airflow within the housing 110. Note that components unnecessary for explanation are omitted in FIG. 3 to make the airflow easier to see. As shown in FIG. 3, an air-cooling fan 111, which is an example of the "air-cooling device" of the present invention, is provided in the approximate center of the housing 110. The air-cooling fan 111 is provided with a gap between it and an exhaust section 110c provided at the upper right end of the housing 110. "A gap between the air-cooling fan 111 and the exhaust section 110c" means that the air-cooling fan 111 is not provided near the exhaust section 110c. "A gap" means, for example, that there is enough space between the air-cooling fan 111 and the exhaust section 110c to accommodate a heat-generating element such as an electronic component, or that there is enough space for the heat-generating element to be actually disposed therein. Note that the air-cooling device may be, for example, a blower or a compressor.

[0035] The air-cooling fan 111 generates an air current from the first intake section 110a and the second intake section 110b toward the exhaust section 110c inside the housing 110. For example, as shown by the solid arrows in Fig. 3, the air-cooling fan 111 rotates to cause air outside the housing 110 to flow into the housing 110 through the first intake section 110a provided at the lower left end of the housing 110 and the second intake section 110b provided at the lower right end of the housing 110, pass through the air-cooling fan 111, and then flow out of the housing 110 through the exhaust section 110c provided at the upper right end of the housing 110.

[0036] Furthermore, a rectifying member 110d for regulating the air flow inside the housing 110 is provided at the lower center end inside the housing 110. The rectifying member 110d is provided upstream of the airflow indicated by the solid arrow in FIG. 3 (lower side in FIG. 3) from the air-cooling fan 111. The upstream side of the airflow refers to the side of the first intake section 110a and the second intake section 110b inside the housing 110 (not the side of the exhaust section 110c). The rectifying member 110d is a convex member that protrudes from the bottom wall of the housing 110 toward the top wall. The height dimension H of the rectifying member 110d is smaller than the width dimension W. The rectifying member 110d rectifies the air intake from the first intake section 110a and the second intake section 110b. The airflow regulating member 110d regulates the air that has flowed into the housing 110 from the first air intake section 110a and the second air intake section 110b so that the air rises in the direction of the air-cooling fan 111, as indicated by the solid arrow.

[0037] Fig. 4 is a diagram of the heat dissipation members provided in the housing 110 as seen from the rear side of the imaging device 100. Fig. 5 is a diagram of the heat dissipation members provided in the housing 110 as seen from the left side of the imaging device 100. As shown in Figs. 4 and 5, a first heat dissipation member 113, a second heat dissipation member 114, a third heat dissipation member 116, and a fourth heat dissipation member 118 are provided in the housing 110. Also provided in the housing 110 are a recording unit 112, a main board 115, and an imaging unit 117.

[0038] The first heat dissipation member 113 and the second heat dissipation member 114 are heat dissipation members attached to the recording unit 112. The first heat dissipation member 113 is composed of a heat sink having a plurality of heat dissipation fins. The first heat dissipation member 113 is provided upstream of the airflow indicated by the solid arrow in FIG. 3 from the air-cooling fan 111 (lower in FIGS. 4 and 5). The second heat dissipation member 114 is composed of a heat transfer sheet or heat dissipation sheet with high thermal conductivity. The second heat dissipation member is, for example, a metal sheet, graphite sheet, copper foil tape, aluminum tape, or the like that can be attached to the recording unit 112.

[0039] The recording unit 112 is a device into which a recording medium for recording imaging data of the imaging device 100 is inserted and removed. The recording unit 112 is provided in the lower left rear portion inside the housing 110. In this example, the recording unit 112 is provided behind the cooling fan 111 and along the rear wall of the housing 110. The recording unit 112 has a medium housing unit 112a and a first electronic component 112b.

[0040] The medium storage section 112a is a section in which a recording medium is stored. The medium storage section 112a is provided with an insertion port 112c for inserting and removing a recording medium. The medium storage section 112a is arranged so that the insertion port 112c is exposed to the outside from the left side wall of the housing 110. The lid section 119 shown in FIG. 1 is attached to the insertion port 112c of the medium storage section 112a. The first electronic component 112b is, for example, an electronic board that performs a process of writing imaging data to the recording medium stored in the medium storage section 112a. The recording medium is, for example, a CFexpress Type B or XQD memory card.

[0041] The first heat dissipation member 113 and the second heat dissipation member 114 cool the recording unit 112 by absorbing heat generated by the recording unit 112 and dissipating it into the air. The first heat dissipation member 113 is attached to the first electronic component 112b of the recording unit 112 and dissipates heat from the first electronic component 112b. The second heat dissipation member 114 is attached to the medium housing unit 112a of the recording unit 112 and dissipates heat from the medium housing unit 112a. Heat is conducted between the medium housing unit 112a and the recording medium housed therein. Therefore, heat dissipated from the medium housing unit 112a includes heat generated by the recording medium. The second heat dissipation member 114 dissipates heat from the medium housing unit 112a and the recording medium housed therein.

[0042] The third heat dissipation member 116 is a heat dissipation member attached to the main board 115, which is an example of the "second electronic member" of the present invention, and is configured as a heat sink with multiple heat dissipation fins. The third heat dissipation member 116 is provided upstream of the air-cooling fan 111 in the airflow indicated by the solid arrow in Fig. 3 (lower in Figs. 4 and 5). The third heat dissipation member 116 is arranged in the same space as the first heat dissipation member 113, upstream of the air-cooling fan 111 in the airflow.

[0043] The main board 115 is an electronic board that performs, for example, image capture control and image processing of the imaging device 100. The main board 115 is provided at the right end inside the housing 110. In this example, the main board 115 is provided to the right of the cooling fan 111, along the right side wall of the housing 110. The third heat dissipation member 116 cools the main board 115 by absorbing heat generated by the main board 115 and dissipating the heat into the air.

[0044] The fourth heat dissipation member 118 is a heat dissipation member attached to the imaging unit 117, and is configured as a heat sink having a plurality of heat dissipation fins. A part of the fourth heat dissipation member 118 is provided on the upstream side of the airflow indicated by the solid arrow in Fig. 3 relative to the air-cooling fan 111 (lower side in Figs. 4 and 5).

[0045] The imaging unit 117 has an imaging element 117a and a third electronic component 117b. The imaging unit 117 is provided in the front part of the housing 110 so as to face the lens 120. In this example, the imaging unit 117 is provided along the front wall of the housing 110, ahead of the cooling fan 111. The imaging element 117a and the third electronic component 117b are arranged such that the third electronic component 117b is on the rear side of the imaging element 117a in the optical axis direction of the lens 120. Light incident from the lens 120 forms an image on the imaging element 117a.

[0046] The imaging element 117a is configured, for example, by a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor. The third electronic component 117b includes a signal processing circuit that performs sampling processing, digital conversion processing, etc. on the captured image signal output from the imaging element 117a. The third electronic component 117b also includes an image processing unit that performs digital signal processing on the captured image signal processed by the signal processing circuit to generate captured image data in, for example, a JPEG (Joint Photographic Experts Group) format.

[0047] Fig. 6 is a perspective view showing an example of the positional relationship between the fourth heat dissipation member 118 and the air-cooling fan 111. As shown in Fig. 6, the fourth heat dissipation member 118 has a base 118a, a first heat dissipation fin 118b, and a second heat dissipation fin 118c.

[0048] The base 118a is a plate-like member to which the third electronic component 117b is attached. The third electronic component 117b is attached to the surface (front surface) of the base 118a disposed inside the housing 110, on which the lens 120 is provided. The base 118a is made of a metal member such as aluminum or copper that has high thermal conductivity.

[0049] The first heat dissipation fin 118b and the second heat dissipation fin 118c are provided on the surface (rear surface) of the base 118a opposite to the side on which the third electronic component 117b is attached. The first heat dissipation fin 118b is a heat dissipation fin provided on the upper part of the rear surface of the base 118a and is composed of multiple fins extending parallel to each other from the base 118a. The second heat dissipation fin 118c is a heat dissipation fin provided on the lower part of the rear surface of the base 118a and is composed of multiple fins extending parallel to each other from the base 118a, similar to the first heat dissipation fin 118b. The multiple fins of the first heat dissipation fin 118b and the second heat dissipation fin 118c are arranged in the left-right direction.

[0050] The first heat dissipation fin 118b and the second heat dissipation fin 118c are fins that dissipate heat from the third electronic component 117b. The fins that dissipate heat from the third electronic component 117b mean that the first heat dissipation fin 118b and the second heat dissipation fin 118c are thermally conductive members that are thermally connected to the third electronic component 117b. For example, the first heat dissipation fin 118b and the second heat dissipation fin 118c may be in direct contact with the third electronic component 117b or may be connected to the third electronic component 117b via another thermally conductive member. In this example, the first heat dissipation fin 118b and the second heat dissipation fin 118c are connected to the third electronic component 117b via the base 118a. The first heat dissipation fin 118b and the second heat dissipation fin 118c dissipate heat conducted from the third electronic component 117b to the base 118a.

[0051] At least a portion of the air-cooling fan 111 is provided between the first heat dissipation fin 118b and the second heat dissipation fin 118c. "Provided between the first heat dissipation fin 118b and the second heat dissipation fin 118c" means that the air-cooling fan 111 is provided between the first heat dissipation fin 118b and the second heat dissipation fin 118c in the air blowing direction of the air-cooling fan 111. In this example, a portion of the front side of the air-cooling fan 111 is provided between the first heat dissipation fin 118b and the second heat dissipation fin 118c. With this arrangement, the first heat dissipation fin 118b and the second heat dissipation fin 118c can dissipate heat from the third electronic component 117b into the airflow of the air-cooling fan 111 (into the airflow indicated by the solid arrow in FIG. 3).

[0052] Fig. 7 is a perspective view showing an example of the positional relationship between the first heat dissipation member 113 and the third heat dissipation member 116. As shown in Fig. 7, the first heat dissipation member 113 has a base 113a and heat dissipation fins 113b. The third heat dissipation member 116 has a base 116a and heat dissipation fins 116b.

[0053] The base 113a of the first heat dissipation member 113 is a plate-shaped member to which the first electronic member 112b of the recording unit 112 is attached. The first electronic member 112b is attached to the surface (rear surface) of the base 113a disposed inside the housing 110, on the side where the rear wall of the housing 110 is provided. The base 113a is made of a metal member such as aluminum or copper that has high thermal conductivity.

[0054] The heat dissipation fins 113b are provided on the surface (front surface) of the base 118a opposite to the side on which the first electronic component 112b is attached, and are composed of multiple fins extending parallel to one another from the base 113a. The heat dissipation fins 113b are fins that dissipate heat from the first electronic component 112b. The fins that dissipate heat from the first electronic component 112b mean that the heat dissipation fins 113b are thermally conductive members that are thermally connected to the first electronic component 112b. For example, the heat dissipation fins 113b may be in direct contact with the first electronic component 112b, or may be connected to the first electronic component 112b via another thermally conductive member. In this example, the heat dissipation fins 113b are connected to the first electronic component 112b via the base 113a. The heat dissipation fins 113b dissipate heat conducted from the first electronic component 112b to the base 118a. As described in Figures 4 and 5, the first heat dissipation member 113 is located upstream of the airflow from the air-cooling fan 111, but it is sufficient that the heat dissipation fins 113b of the first heat dissipation member 113 are located upstream of the airflow from the air-cooling fan 111, and the base 118a may extend to the height of the air-cooling fan 111.

[0055] Base 116a of third heat dissipation member 116 is a plate-shaped member to which main board 115 is attached. Main board 115 is attached to the surface of base 116a, which is disposed inside housing 110, on the side where the right wall of housing 110 is provided (the right surface). Base 116a is made of a metal member such as aluminum or copper that has high thermal conductivity.

[0056] The heat dissipation fins 116b are provided on the surface (left surface) of the base 116a opposite to the side on which the main board 115 is attached, and are composed of a plurality of fins extending parallel to one another from the base 116a. The heat dissipation fins 116b are fins that dissipate heat from the main board 115. The fins that dissipate heat from the main board 115 mean that the heat dissipation fins 116b are thermally conductive members that are thermally connected to the main board 115. For example, the heat dissipation fins 116b may be in direct contact with the main board 115, or may be connected to the main board 115 via another thermally conductive member. In this example, the heat dissipation fins 116b are connected to the main board 115 via the base 116a. The heat dissipation fins 116b dissipate heat conducted from the main board 115 to the base 116a.

[0057] The arrangement direction of the heat dissipation fins 113b of the first heat dissipation member 113 is different from the arrangement direction of the heat dissipation fins 116b of the third heat dissipation member 116. The arrangement direction of the heat dissipation fins 113b and the arrangement direction of the heat dissipation fins 116b differ by, for example, about 90°. The multiple fins of the heat dissipation fins 113b are arranged in the left-right direction. In contrast, the multiple fins of the heat dissipation fins 116b are arranged in the front-rear direction.

[0058] The arrangement intervals of the heat dissipation fins 113b in the first heat dissipation member 113, the arrangement intervals of the heat dissipation fins 116b in the third heat dissipation member 116, and the arrangement intervals of the first heat dissipation fins 118b and the second heat dissipation fins 118c (see Figure 6) in the fourth heat dissipation member 118 are different from each other.

[0059] The arrangement direction of the heat dissipation fins 113b of the first heat dissipation member 113 and the arrangement direction of the first heat dissipation fins 118b and second heat dissipation fins 118c of the fourth heat dissipation member 118 are the same, i.e., the left-right direction. However, the arrangement interval of the heat dissipation fins 113b and the arrangement interval of the first heat dissipation fins 118b and second heat dissipation fins 118c are different. For this reason, it is difficult to arrange the heat dissipation fins of both heat dissipation members alternately so that they do not interfere with each other. Therefore, notches 113c are formed in the heat dissipation fins 113b of the first heat dissipation member 113 to prevent the heat dissipation fins from interfering with each other regardless of the difference in arrangement interval between the two heat dissipation fins.

[0060] As described above, the imaging device 100 of this embodiment includes the first heat dissipation member 113, which is provided upstream of the air-cooling fan 111 in the airflow and includes heat dissipation fins 113b that dissipate heat from the first electronic component 112b in the recording unit 112, and the second heat dissipation member 114, which is made of a heat dissipation sheet that dissipates heat from the medium containing portion 112a in the recording unit 112. With this configuration, heat generated in the first electronic component 112b of the recording unit 112 is conducted to the first heat dissipation member 113, and heat generated in the medium containing portion 112a of the recording unit 112 is conducted to the second heat dissipation member 114, so that the first heat dissipation member 113 and the second heat dissipation member 114 to which the heat has been conducted can be effectively cooled by a low-temperature airflow generated by the air-cooling fan 111 using outside air drawn in from the first intake portion 110a and the second intake portion 110b. By using the first heat dissipation member 113 and the second heat dissipation member 114 to dissipate heat from the recording unit 112 in this manner, the cooling performance of the recording unit 112 can be improved.

[0061] The imaging device 100 is further provided with a third heat dissipation member 116 that is disposed upstream of the air-cooling fan 111 in the airflow and includes heat dissipation fins 116b that dissipate heat from the main board 115, and the arrangement direction of the heat dissipation fins 113b of the first heat dissipation member 113 that dissipates heat from the recording unit 112 is different from the arrangement direction of the heat dissipation fins 116b of the third heat dissipation member 116 that dissipates heat from the main board 115. This configuration can suppress interference between heat dissipation from the heat dissipation fins 113b of the first heat dissipation member 113 and heat dissipation from the heat dissipation fins 116b of the third heat dissipation member 116. This can further improve the cooling performance of the recording unit 112.

[0062] The imaging device 100 further includes a fourth heat dissipation member 118 including first and second heat dissipation fins 118b and 118c that dissipate heat from the third electronic component 117b in the imaging unit 117, and at least a portion of the cooling fan 111 is provided between the first and second heat dissipation fins 118b and 118c. This configuration allows for effective use of the space within the housing 110, and enables the imaging device 100 to be made smaller.

[0063] In the imaging device 100, the arrangement intervals of the heat dissipation fins 113b on the first heat dissipation member 113, the arrangement intervals of the heat dissipation fins 116b on the third heat dissipation member 116, and the arrangement intervals of the first heat dissipation fins 118b and the second heat dissipation fins 118c on the fourth heat dissipation member 118 are different. With this configuration, the arrangement intervals of the heat dissipation fins are varied depending on the heat dissipation amount of the electronic components attached to each heat dissipation member and the flow path of the cooling air, thereby further improving the cooling performance of the recording unit 112, which dissipates a large amount of heat. In addition, in the imaging device 100, the notch portions 113c are provided in the heat dissipation fins 113b of the first heat dissipation member 113, so that interference between the heat dissipation fins 113b and the first heat dissipation fins 118b and the second heat dissipation fins 118c of the fourth heat dissipation member 118 can be prevented, and the heat dissipation performance of the recording unit 112 by the first heat dissipation member 113 can be maintained.

[0064] <Modifications of the first heat dissipation member 113> FIG. 8 is a diagram showing a first modified example of the configuration of the first heat dissipation member 113. As shown in FIG. 8, holes 113d may be provided in each of the heat dissipation fins 113b of the first heat dissipation member 113. The holes 113d in the first modified example are multiple circular holes. The shape and number of the holes are not particularly limited. Furthermore, holes may be provided in the heat dissipation fins of other heat dissipation members (third heat dissipation member 116, fourth heat dissipation member 118) as well, without being limited to the first heat dissipation member 113.

[0065] 9 is a diagram showing a second modified example of the configuration of the first heat dissipation member 113. As shown in FIG. 9, the heat dissipation fins 113b of the first heat dissipation member 113 may each be provided with a cut-and-raised portion 113e. The cut-and-raised portion 113e is formed by cutting the heat dissipation fin 113b by punching or the like and bending the cut portion to raise the cut portion into, for example, an L-shape. Note that the heat dissipation fins of the third heat dissipation member 116 and the fourth heat dissipation member 118 may also be provided with a cut-and-raised portion in a similar manner.

[0066] In this way, by providing holes 113d or cut-outs 113e in the heat dissipation fins 113b of the first heat dissipation member 113, the flow of heat generated in the first electronic component 112b (recording section 112) can be prevented from stagnating between the heat dissipation fins 113b, thereby improving the heat dissipation effect.

[0067] <Attachment example of second heat dissipation member 114> Fig. 10 is a diagram showing a first example of attachment of second heat dissipation member 114. As shown in Fig. 10, a graphite sheet, which is an example of second heat dissipation member 114, is attached across left wall 110e of housing 110 and medium containing section 112a. Specifically, it is attached across from the inner surface of left wall 110e to the top surface of medium containing section 112a. This allows heat generated in medium containing section 112a to be conducted to wall 110e of housing 110 via the graphite sheet, thereby improving the heat dissipation effect.

[0068] Fig. 11 is a diagram showing a second example of attachment of the second heat dissipation member 114. As shown in Fig. 11, a plurality of second heat dissipation members 114 (e.g., graphite sheets) may be attached in layers. For example, a second heat dissipation member 114a may be attached across the left wall 110e of the housing 110 and the medium containing section 112a, and another second heat dissipation member 114b may be attached between the medium containing section 112a.

[0069] Furthermore, the second heat dissipation member 114b may be attached so that it extends from the medium containing portion 112a and extends over other portions of the housing 110 or over the first electronic component 112b of the recording unit 112. In this example, the second heat dissipation member 114b is attached so as to extend over the medium containing portion 112a and the first electronic component 112b. While two graphite sheets are attached in this example, this is not limiting. For example, one graphite sheet may be attached so as to extend over the housing 110, the medium containing portion 112a, and the first electronic component 112b. According to the second attachment example, heat generated in the medium containing portion 112a is not only conducted to the housing 110 via the graphite sheet, but also conducted to the first heat dissipation member 113 attached to the first electronic component 112b via the graphite sheet and the first electronic component 112b, thereby further improving the heat dissipation effect.

[0070] 12 is a diagram showing a third example of attachment of the second heat dissipation member 114. As shown in FIG. 12, the second heat dissipation member 114c attached to and overlapping the second heat dissipation member 114a (e.g., a graphite sheet) may be attached so that it extends below the medium containing portion 112a and straddles the first heat dissipation member 113 to which the first electronic component 112b is attached. According to the third example of attachment, heat generated in the medium containing portion 112a can be conducted not only to the housing 110 via the graphite sheet, but also to the first heat dissipation member 113, thereby further improving the heat dissipation effect.

[0071] Fig. 13 is a diagram showing a fourth example of attachment of the second heat dissipation member 114. As shown in Fig. 13, the second heat dissipation member 114 (for example, a graphite sheet) may be attached to the lid 119 of the medium containing section 112a.

[0072] The lid 119 is attached to the left wall 110e of the housing 110 so as to be able to open and close by rotating about a rotation axis 119c. Figure 13 shows the lid 119 in a closed state. The lid 119 has a fixing member 119a that dissipates heat from the medium containing section 112a, and a resin cover 119b provided in the center of the fixing member 119a. The fixing member 119a is made of a metal member such as aluminum or copper that has high thermal conductivity.

[0073] Second heat dissipation member 114 is attached across left wall 110e and lid 119 of housing 110. Specifically, second heat dissipation member 114 is attached across the outer surface of left wall 110e, the outer surface of fixing member 119a, and the inner surface of resin cover 119b. Second heat dissipation member 114 is connected to fixing member 119a.

[0074] Figure 14 is a diagram showing a state in which lid 119 shown in Figure 13 is open. As shown in Figure 14, when lid 119 is open, insertion slot 112c of medium containing unit 112a is exposed from left wall 110e of housing 110, allowing the insertion and removal of a recording medium. According to the third attachment example, heat generated in medium containing unit 112a can be conducted to wall 110e of housing 110 via the graphite sheet attached to lid 119, thereby improving the heat dissipation effect.
