In this embodiment, directions indicated by "upper direction", "lower direction", "left direction", "right direction", "front direction", and "rear direction" are set as relative directions with respect to the camera shown in each figure for the purpose of convenience of explanation.

[0100] <Camera of Embodiment>

[0101] Figure 1 is a simple perspective view showing an example of the camera 100 in the embodiment, as viewed from the left front. Figure 2 is a simple perspective view showing the camera 100 shown in Fig. 1, as viewed from the right front. Figure 1 As an example of a camera, for example, a digital camera or a single-lens reflex camera capable of taking moving pictures, or the like can be given. As shown in Fig. 1, the camera 100 includes a frame 110 constituting a main body of the camera 100, and a lens 120 mounted to the frame 110. Figure 1 Figure 2

[0102] ​​The frame body 110 is formed in a substantially cubic shape. A first air inlet portion 110a is provided at a lower left end portion of the frame body 110. Also, a second air inlet portion 110b is provided at a lower right end portion of the frame body 110. The first air inlet portion 110a and the second air inlet portion 110b are opening portions that can suck air outside the frame body 110 into the inside of the frame body 110. The first air inlet portion 110a and the second air inlet portion 110b are, for example, constituted by a plurality of openings in a slit shape.

[0103] Also, an air outlet portion 110c is provided at an upper right end portion of the frame body 110. The air outlet portion 110c is an opening portion that can discharge air inside the frame body 110 to the outside of the frame body 110. The air outlet portion 110c is, for example, constituted by a plurality of openings in a slit shape.

[0104] The openings constituting the air outlet portion 110c are, for example, formed from the upper wall to the right side wall of the frame body 110. Although not shown in the drawing, the openings constituting the first air inlet portion 110a are formed from the left side wall to the lower wall, and the openings constituting the second air inlet portion 110b are formed from the right side wall to the lower wall.

[0105] Also, a cover portion 119 of a recording portion 112 (described later) for insertion and extraction of a recording medium is provided at a lower portion of the left side wall of the frame body 110. Figure 5 Image pickup data of the image pickup apparatus 100 is recorded in the recording medium.

[0106] The lens 120 is mounted on the front surface side (front surface) of the frame body 110. The lens 120 is replaceable. The lens 120 includes at least an imaging lens such as a focusing lens or a zoom lens.

[0107] Figure 3 is a drawing showing an example of the flow of air inside the frame body 110. In Figure 3 , parts unnecessary for easy observation of the flow of air are omitted from the description. As Figure 3 indicated in the drawing, in the frame body 110, an air-cooling fan 111 as an example of an "air-cooling device" of the present application is provided at a substantially central portion thereof. The air-cooling fan 111 is provided with a space from the air outlet portion 110c provided at the upper right end portion of the frame body 110. The space from the air outlet portion 110c means that the air-cooling fan 111 is not provided in the vicinity of the air outlet portion 110c. The space means, for example, that a space of a degree in which a heat generating body such as an electronic part can be disposed or a space in which an actual disposition is possible is present between the air-cooling fan 111 and the air outlet portion 110c. In addition, the air-cooling device can be, for example, a blower or a compressor.

[0108] The air-cooling fan 111 generates an air current from the first air inlet portion 110a and the second air inlet portion 110b toward the air outlet portion 110c inside the frame body 110. For example, the air-cooling fan 111 generates the air current by rotating, as Figure 3air outside the frame body 110 flows into the frame body 110 from the first air inlet 110a provided at the lower left end portion of the frame body 110 and the second air inlet 110b provided at the lower right end portion of the frame body 110, and is caused to flow out to the outside of the frame body 110 from the air outlet 110c provided at the upper right end portion of the frame body 110 by the air cooling fan 111.

[0109] Further, a flow regulating member 110d for regulating the flow of air in the frame body 110 is provided at the central lower end portion in the frame body 110. The flow regulating member 110d is provided at the upstream side of the air flow (the lower side in Figure 3 Figure 3 Figs. 16 and 17) indicated by the solid arrows. The upstream side of the air flow refers to the first air inlet 110a and the second air inlet 110b side (not the air outlet 110c side) in the frame body 110. The flow regulating member 110d is a convex portion type member protruding from the lower wall of the frame body 110 toward the upper wall direction. The height dimension H of the flow regulating member 110d is smaller than the width dimension W. The flow regulating member 110d regulates the intake of air from the first air inlet 110a and the second air inlet 110b. As indicated by the solid arrows, the flow regulating member 110d regulates the air flowing into the frame body 110 from the first air inlet 110a and the second air inlet 110b to rise in the direction of the air cooling fan 111.

[0110] Figure 4 is a view of the heat radiating members provided in the frame body 110 as viewed from the rear side of the camera 100. Figure 5 is a view of the heat radiating members provided in the frame body 110 as viewed from the left side of the camera 100. As Figure 4 Figure 5 indicated in Figs. 16 and 17, the first heat radiating member 113, the second heat radiating member 114, the third heat radiating member 116, and the fourth heat radiating member 118 are provided in the frame body 110. Further, the recording section 112, the main substrate 115, and the imaging section 117 are provided in the frame body 110.

[0111] The first heat radiating member 113 and the second heat radiating member 114 are heat radiating members mounted to the recording section 112. The first heat radiating member 113 is composed of a heat sink having a plurality of heat radiating fins. The first heat radiating member 113 is provided at the upstream side of the air flow (the lower side in Figure 3 Figure 4 Figure 5 The second heat radiating member 114 is composed of a heat transfer sheet or a heat radiating sheet having high heat transfer properties. The second heat radiating member is, for example, a metal sheet, a graphite sheet, a copper adhesive tape, an aluminum adhesive tape, or the like which can be attached to the recording section 112.

[0112] ​​​​The recording section 112 is a device into which a recording medium for recording the image pickup data of the image pickup device 100 is inserted. The recording section 112 is provided at the lower left of the rear portion inside the frame 110. In this example, the recording section 112 is provided along the rear wall of the frame 110 on the more rear side than the air cooling fan 111. The recording section 112 has a medium housing section 112a and a first electronic component 112b.

[0113] The medium housing section 112a is a portion that houses the recording medium. An insertion port 112c for inserting and removing the recording medium is provided in the medium housing section 112a. The medium housing section 112a is configured so that the insertion port 112c is exposed to the outside from the left side wall of the frame 110. The insertion port 112c of the medium housing section 112a is provided with a cover section 119 as shown. The first electronic component 112b is, for example, an electronic substrate that performs processing of writing the image pickup data to the recording medium housed in the medium housing section 112a. The recording medium is, for example, a memory card of CFexpress Type B or XQD. Figure 1

[0114] The first and second heat dissipation components 113 and 114 cool the recording section 112 by absorbing heat emitted from the recording section 112 and dissipating the heat to the air. The first heat dissipation component 113 is attached to the first electronic component 112b of the recording section 112 and performs heat dissipation of the first electronic component 112b. The second heat dissipation component 114 is attached to the medium housing section 112a of the recording section 112 and performs heat dissipation of the medium housing section 112a. Heat conduction is performed between the medium housing section 112a and the recording medium housed therein. Therefore, heat generated by the recording medium is included in the heat dissipation from the medium housing section 112a. The second heat dissipation component 114 performs heat dissipation of the medium housing section 112a and the recording medium housed therein.

[0115] The third heat dissipation component 116 is a heat dissipation component that is attached to the main substrate 115, which is an example of the "second electronic component" of the present application, and is composed of a heat sink having a plurality of heat dissipation fins. The third heat dissipation component 116 is provided on the more upstream side of the air current than the air cooling fan 111 (the lower side in FIGS. 1 and 2). Figure 3 Figure 4 Figure 5 The third heat dissipation component 116 is provided in the same space as the first heat dissipation component 113 on the more upstream side of the air current than the air cooling fan 111.

[0116] The main substrate 115 is, for example, an electronic substrate that performs image pickup control or image processing of the image pickup device 100. The main substrate 115 is provided at the right end portion inside the frame 110. In this example, the main substrate 115 is provided along the right side wall of the frame 110 on the more right side than the air cooling fan 111. The third heat dissipation component 116 cools the main substrate 115 by absorbing heat emitted from the main substrate 115 and dissipating the heat to the air.​​​

[0117] The fourth heat dissipation member 118 is a heat dissipation member installed to the imaging section 117 and is composed of a heat sink having a plurality of heat dissipation fins. The fourth heat dissipation member 118 is provided at a portion thereof on the upstream side of the air flow indicated by the solid arrow in Fig. 1 (the lower side in Figs. 2 and 3) than the air cooling fan 111. Figure 3 Figure 4 Figure 5

[0118] The imaging section 117 has an imaging element 117a and a third electronic member 117b. The imaging section 117 is provided in the front portion in the frame 110 in opposition to the lens 120. In the present example, the imaging section 117 is provided on the front side than the air cooling fan 111 along the front wall of the frame 110. With respect to the imaging element 117a and the third electronic member 117b, the third electronic member 117b is disposed on the back side of the imaging element 117a in the optical axis direction of the lens 120. Light radiated from the lens 120 is imaged on the imaging element 117a.

[0119] The imaging element 117a is composed of, for example, a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor, or the like. The third electronic member 117b includes a signal processing circuit that performs sampling processing or digital conversion processing, or the like, on an imaging image signal output from the imaging element 117a. Further, the third electronic member 117b includes an image processing section that performs digital signal processing on the imaging image signal processed by the signal processing circuit to generate imaging image data in, for example, a JPEG (Joint Photographic Experts Group) format, or the like.

[0120] Figure 6 is a perspective view showing an example of the arrangement relationship of the fourth heat dissipation member 118 and the air cooling fan 111. As shown in Fig. 4, the fourth heat dissipation member 118 has a base portion 118a, first heat dissipation fins 118b, and second heat dissipation fins 118c. Figure 6

[0121] The base portion 118a is a plate-shaped member on which the third electronic member 117b is installed. The third electronic member 117b is installed on a surface (front surface) of the base portion 118a disposed on the side on which the lens 120 is disposed in the frame 110. The base portion 118a is composed of a metal member such as aluminum or copper having high thermal conductivity.

[0122] ​​​​The first heat dissipation fin 118b and the second heat dissipation fin 118c are provided on a surface (a rear surface) of the base 118a on a side opposite to a side on which the third electronic component 117b is mounted. The first heat dissipation fin 118b is a heat dissipation fin provided on an upper portion of the rear surface of the base 118a and is composed of a plurality of fins extending from the base 118a in parallel with each other. The second heat dissipation fin 118c is a heat dissipation fin provided on a lower portion of the rear surface of the base 118a and is composed of a plurality of fins extending from the base 118a in parallel with each other, like the first heat dissipation fin 118b. The plurality of fins of the first heat dissipation fin 118b and the second heat dissipation fin 118c are arranged in the left-right direction.

[0123] The first heat dissipation fin 118b and the second heat dissipation fin 118c are fins that dissipate heat of the third electronic component 117b. The fins that dissipate heat of the third electronic component 117b mean that the first heat dissipation fin 118b and the second heat dissipation fin 118c are heat 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 can be directly connected to the third electronic component 117b, or can be connected to the third electronic component 117b via other heat conductive members. 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.

[0124] The air-cooling fan 111 is provided at least in part between the first heat dissipation fin 118b and the second heat dissipation fin 118c. The air-cooling fan 111 is provided between the first heat dissipation fin 118b and the second heat dissipation fin 118c in the air supply 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 configuration, the first heat dissipation fin 118b and the second heat dissipation fin 118c can release heat of the third electronic component 117b into the airflow of the air-cooling fan 111 (into the airflow indicated by the solid arrow in FIG. 11). Figure 3

[0125] Figure 7 is a perspective view showing an example of the configuration relationship of the first heat dissipation member 113 and the third heat dissipation member 116. As shown in Figure 7 , the first heat dissipation member 113 has a base 113a and a heat dissipation fin 113b. Also, the third heat dissipation member 116 has a base 116a and a heat dissipation fin 116b.

[0126] ​The base 113a of the first heat dissipation component 113 is a plate-shaped component on which the first electronic component 112b of the recording unit 112 is mounted. The first electronic component 112b is mounted on the side (rear side) of the base 113a, which is disposed within the frame 110, on the side where the rear wall of the frame 110 is located. The base 113a is made of a metal component such as aluminum or copper, which has high thermal conductivity.

[0127] Heat dissipation fins 113b are disposed on the front side of the base 118a opposite to the side where the first electronic component 112b is mounted, and are composed of a plurality of fins extending parallel to each other from the base 113a. Heat dissipation fins 113b are fins for dissipating heat from the first electronic component 112b. A fin for dissipating heat from the first electronic component 112b means that heat dissipation fins 113b are heat-conducting components thermally connected to the first electronic component 112b. For example, heat dissipation fins 113b can be directly connected to the first electronic component 112b, or they can be connected to the first electronic component 112b via other heat-conducting components. In this example, heat dissipation fins 113b are connected to the first electronic component 112b via the base 113a. Heat dissipation fins 113b dissipate heat conducted from the first electronic component 112b to the base 118a. Furthermore, as... Figure 4 and Figure 5 As explained in the document, the first heat dissipation component 113 is located upstream of the airflow than the air-cooled fan 111, but it is sufficient that the heat dissipation fins 113b in the first heat dissipation component 113 are located upstream of the airflow than the air-cooled fan 111, and the base 118a can extend to the height of the air-cooled fan 111.

[0128] The base 116a of the third heat dissipation component 116 is a plate-shaped component on which the main substrate 115 is mounted. The main substrate 115 is mounted on the side (right side) of the base 116a, which is located within the frame 110, on the side where the right wall of the frame 110 is located. The base 116a is made of a metal component such as aluminum or copper, which has high thermal conductivity.

[0129] Heat dissipation fins 116b are disposed on the side of the base 116a opposite to the side on which the main substrate 115 is mounted (the left side), and are composed of a plurality of fins extending parallel to each other from the base 116a. Heat dissipation fins 116b are fins for dissipating heat from the main substrate 115. A fin for dissipating heat from the main substrate 115 means that heat dissipation fins 116b are thermally connected to the main substrate 115. For example, heat dissipation fins 116b can be directly connected to the main substrate 115, or they can be connected to the main substrate 115 via other thermally connected components. In this example, heat dissipation fins 116b are connected to the main substrate 115 via the base 116a. Heat dissipation fins 116b dissipate heat conducted from the main substrate 115 to the base 116a.

[0130] The arrangement direction of the heat dissipation fins 113b in the first heat dissipation component 113 is different from the arrangement direction of the heat dissipation fins 116b in the third heat dissipation component 116. For example, the arrangement direction of the heat dissipation fins 113b differs from that of the heat dissipation fins 116b by approximately 90°. Multiple fins in the heat dissipation fins 113b are arranged in a left-right direction. In contrast, multiple fins in the heat dissipation fins 116b are arranged in a front-back direction.

[0131] The arrangement spacing of the heat dissipation fins 113b in the first heat dissipation component 113, the arrangement spacing of the heat dissipation fins 116b in the third heat dissipation component 116, and the arrangement spacing of the first heat dissipation fin 118b and the second heat dissipation fin 118c in the fourth heat dissipation component 118 (see reference). Figure 6 The configuration intervals of the two are different from each other.

[0132] The arrangement direction of the heat dissipation fins 113b in the first heat dissipation component 113 is the same left-right direction as the arrangement direction of the first heat dissipation fins 118b and the second heat dissipation fins 118c in the fourth heat dissipation component 118. However, the arrangement spacing of the heat dissipation fins 113b is different from that of the first heat dissipation fins 118b and the second heat dissipation fins 118c. Therefore, it is difficult to arrange the heat dissipation fins alternately to avoid interference between the heat dissipation fins of the two heat dissipation components. Therefore, a cutout 113c is formed on the heat dissipation fins 113b of the first heat dissipation component 113 so that the heat dissipation fins do not interfere with each other regardless of the difference in the arrangement spacing of the two heat dissipation fins.

[0133] As described above, the imaging device 100 of this embodiment includes: a first heat dissipation member 113, which is disposed upstream of the airflow from the air-cooled fan 111 and includes heat dissipation fins 113b for dissipating heat from the first electronic component 112b in the recording unit 112; and a second heat dissipation member 114, which is composed of heat dissipation fins for dissipating heat from the medium container 112a in the recording unit 112. According to this structure, heat generated in the first electronic component 112b of the recording unit 112 can be conducted to the first heat dissipation member 113, and heat generated in the medium container 112a of the recording unit 112 can be conducted to the second heat dissipation member 114. Furthermore, the external gas introduced from the first air intake 110a and the second air intake 110b is used to effectively cool the heat-conducting first heat dissipation member 113 and the second heat dissipation member 114 by passing through the low-temperature airflow generated by the air-cooled fan 111. Thus, by using the first heat dissipation component 113 and the second heat dissipation component 114 to dissipate heat from the recording unit 112, the cooling performance of the recording unit 112 can be improved.

[0134] Further, the imaging device 100 is provided with a third heat dissipation member 116 which is disposed on an upstream side of the airflow than the air cooling fan 111 and which includes a heat dissipation fin 116b which performs heat dissipation of the main substrate 115, and the arrangement direction of the heat dissipation fin 113b of the first heat dissipation member 113 which performs heat dissipation of the recording section 112 is different from the arrangement direction of the heat dissipation fin 116b of the third heat dissipation member 116 which performs heat dissipation of the main substrate 115. According to this structure, interference of heat dissipation from the heat dissipation fin 113b in the first heat dissipation member 113 and heat dissipation from the heat dissipation fin 116b in the third heat dissipation member 116 can be suppressed. Thus, the cooling performance of the recording section 112 can be further improved.

[0135] Further, the imaging device 100 is provided with a fourth heat dissipation member 118 which includes a first heat dissipation fin 118b and a second heat dissipation fin 118c which perform heat dissipation of the third electronic component 117b in the imaging section 117, and at least a part of the air cooling fan 111 is disposed between the first heat dissipation fin 118b and the second heat dissipation fin 118c. According to this structure, the space inside the frame 110 can be effectively used, and the imaging device 100 can be miniaturized.

[0136] Further, in the imaging device 100, the arrangement interval of the heat dissipation fin 113b in the first heat dissipation member 113, the arrangement interval of the heat dissipation fin 116b in the third heat dissipation member 116, and the arrangement interval of the first heat dissipation fin 118b and the second heat dissipation fin 118c in the fourth heat dissipation member 118 are different. According to this structure, by making the arrangement interval of the heat dissipation fin different according to the amount of heat dissipation of the electronic component mounted on each heat dissipation member or the flow path of the cooling air, the cooling performance of the recording section 112 which has a large amount of heat dissipation can be further improved. Further, in the imaging device 100, the notch portion 113c is provided on the heat dissipation fin 113b of the first heat dissipation member 113, so interference of the heat dissipation fin 113b and the first heat dissipation fin 118b and the second heat dissipation fin 118c of the fourth heat dissipation member 118 can be prevented, and the heat dissipation performance of the recording section 112 based on the first heat dissipation member 113 can be maintained.

[0137] <First Heat Dissipation Member 113>

[0138] Figure 8 is a view which shows a first modification example of the structure of the first heat dissipation member 113. As shown in FIG. 15, the first heat dissipation member 113 is provided with a heat dissipation fin 113b which performs heat dissipation of the recording section 112, and the arrangement direction of the heat dissipation fin 113b is different from the arrangement direction of the heat dissipation fin 116b of the third heat dissipation member 116 which performs heat dissipation of the main substrate 115. Figure 8As shown in FIG. 1 1, in the heat dissipation fins 113b of the first heat dissipation member 113, holes 113d can be provided in each of the heat dissipation fins 113b. The holes 113d in the first modification example are provided with a plurality of circular holes. However, the shape and number of the holes are not particularly limited. Also, the holes can be provided in the heat dissipation fins of the other heat dissipation members (the third heat dissipation member 116, the fourth heat dissipation member 118) as well.

[0139] Figure 9 FIG. 12 is a view showing a second modification example of the structure of the first heat dissipation member 113. As shown in FIG. 12, in the heat dissipation fins 113b of the first heat dissipation member 113, protrusions 113e can be provided in each of the heat dissipation fins 113b. The protrusions 113e are formed by cutting the heat dissipation fins 113b by punching or the like and bending the cut portions to form the cut portions in, for example, an L shape. Also, the protrusions can be provided in the heat dissipation fins of the third heat dissipation member 116 and the fourth heat dissipation member 118 as well. Figure 9

[0140] Thus, by providing the holes 113d or the protrusions 113e in the heat dissipation fins 113b of the first heat dissipation member 113, the flow of heat generated in the first electronic member 112b (the recording section 112) can be prevented from stagnating between the heat dissipation fins 113b, and thus the heat dissipation effect can be improved.

[0141] <First Heat Dissipation Member 113>

[0142] Figure 10 FIG. 13 is a view showing a first attachment example of the second heat dissipation member 114. As shown in FIG. 13, a graphite sheet, which is an example of the second heat dissipation member 114, is attached across the left side wall 110e of the frame 110 and the medium accommodating section 112a. Specifically, the graphite sheet is attached across from the inner side surface of the left side wall 110e to the upper surface of the medium accommodating section 112a. Thus, heat generated in the medium accommodating section 112a can be conducted to the wall 110e of the frame 110 via the graphite sheet, and thus the heat dissipation effect can be improved. Figure 10

[0143] FIG. 14 is a view showing a second attachment example of the second heat dissipation member 114. As shown in FIG. 14, the second heat dissipation member 114 (for example, a graphite sheet) can be attached in multiple layers. For example, another second heat dissipation member 114b can be attached between the second heat dissipation member 114a, which is attached across the left side wall 110e of the frame 110 and the medium accommodating section 112a, and the medium accommodating section 112a. Figure 11 Figure 11

[0144] ​​​Furthermore, the overlapping second heat dissipation component 114b can extend from the media receiving portion 112a and extend across other parts of the frame 110 or the first electronic component 112b of the recording portion 112. In this example, the overlapping second heat dissipation component 114b is attached across the media receiving portion 112a and the first electronic component 112b. In addition, two graphite sheets are attached in this example, but it is not limited to this. For example, one graphite sheet can be attached across the frame 110, the media receiving portion 112a, and the first electronic component 112b. According to the second attachment example, not only is the heat generated in the media receiving portion 112a conducted to the frame 110 via the graphite sheet, but it can also be conducted to the first heat dissipation component 113 mounted on the first electronic component 112b via the graphite sheet and the first electronic component 112b, thereby further improving the heat dissipation effect.

[0145] Figure 12 This is a diagram showing the third attachment example of the second heat dissipation component 114. (See attached diagram.) Figure 12 As shown, the second heat dissipation component 114c, which overlaps and is attached to the second heat dissipation component 114a (e.g., a graphite sheet), can be attached such that it extends downward toward the dielectric container 112a and crosses the first heat dissipation component 113 on which the first electronic component 112b is mounted. According to the third attachment example, not only is the heat generated in the dielectric container 112a conducted to the frame 110 via the graphite sheet, but it can also be conducted to the first heat dissipation component 113, thereby further improving the heat dissipation effect.

[0146] Figure 13 This is the fourth attached figure showing the second heat dissipation component 114. (See attached figure.) Figure 13 As shown, the second heat dissipation component 114 (e.g., a graphite sheet) can be attached to the cover portion 119 of the medium receiving portion 112a.

[0147] The cover 119 is mounted on the left side wall 110e of the frame 110 in a rotatable manner by rotating about the rotation axis 119c. Figure 13 The cover 119 indicates the closed state. The cover 119 has a fixing member 119a for heat dissipation of the medium receiving part 112a and a resin cover 119b disposed in the center of the fixing member 119a. The fixing member 119a is made of a metal component such as aluminum or copper with high thermal conductivity, for example.

[0148] The second heat dissipation component 114 is attached across the left side wall 110e and the cover 119 of the frame 110. Specifically, the second heat dissipation component 114 is attached across the outer side of the left side wall 110e, the outer side of the fixing component 119a, and the inner side of the resin cover 119b.

[0149] The second heat dissipation component 114 is connected to the fixing component 119a.

[0150] Figure 14 is a diagram showing a state in which the cover portion 119 is opened. Figure 13 Figure 14 As shown, by opening the cover portion 119, the insertion port 112c of the medium accommodating portion 112a is exposed from the wall 110e of the frame body 110 on the left side to become a state in which a recording medium can be inserted and removed. According to the third attachment example, heat generated in the medium accommodating portion 112a can be conducted to the wall 110e of the frame body 110 via the graphite sheet attached to the cover portion 119, and thus the heat dissipation effect can be improved.
