Description

[Technical field]

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

[0002] In imaging devices, as the resolution and frame rate of recorded images increase, the signal processing load and power consumption become larger, and the amount of heat generated by signal processing units such as the imaging unit and recording medium (recording media) increases.

[0003] The performance of electronic components in an imaging device decreases at high temperatures, so it is necessary to provide a cooling structure inside the device. A heat dissipation structure that forcibly cools the inside of an imaging device is disclosed in Patent Document 1. The imaging device in Patent Document 1 has a built-in forced air-cooling flow path, and after external air supplied from an air intake on the back of the device is passed through the forced air-cooling flow path for heat exchange, the air is exhausted from an exhaust port on the side of the device, thereby cooling the main heat source inside the device.

[0004] [Patent Document 1] Patent Publication No. 2022-77037 Summary of the Invention [Problem to be solved by the invention]

[0005] However, Patent Document 1 does not take into consideration cooling of the recording medium. If a new structure for cooling the recording medium were added, the device would become larger. As the writing bit rate increases due to future improvements in image quality, the amount of heat generated by the recording medium is expected to increase further, making it necessary to efficiently cool the recording medium.

[0006] An object of the present invention is to efficiently cool a recording medium while suppressing an increase in size. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the imaging device of the present invention is characterized in having a gripping portion that is disposed on the imaging device body and is gripped during use; a control board provided on the imaging device body and approximately perpendicular to the optical axis direction; a storage portion mounted on the control board at a position that does not overlap with the gripping portion when viewed from the optical axis direction and capable of storing a recording medium; and a heat dissipation duct that is disposed at a position that does not overlap with the gripping portion when viewed from the optical axis direction and is thermally connected to the storage portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] (First embodiment) 1(a) and (b) are perspective views of an imaging device according to a first embodiment of the present invention. To simplify the following description, the XYZ coordinate system is defined as follows. The direction of the imaging optical axis (optical axis O direction) of the imaging device 100 is the Z axis, and the subject direction is positive (+Z). On a plane perpendicular to the Z axis, the width direction (left-right direction) of the imaging device 100 is the X axis, and the right side as viewed from the subject side (+Z side) is positive (+X). The top-bottom direction of the imaging device 100 is the Y axis, and the direction toward the sky is positive (+Y). Therefore, FIG. 1(a) is a front perspective view of the imaging device 100, and FIGS. 1(b) and (c) are rear perspective views of the imaging device 100.

[0012] The imaging device 100 is composed of an imaging device body 102 and a lens 103. Inside the imaging device body 102, components including the main functions of an imaging device are arranged, such as a control circuit board 110 (see FIG. 2(a)), an imaging element 116 (see FIG. 2(b)), a power supply unit, a recording unit for recording images, and various operation units. As shown in FIG. 1(a), a lens 103 is attached to the subject side (+Z side) of the imaging device body 102. The lens 103 is replaceable according to the shooting conditions.

[0013] As shown in Fig. 1(a), an exhaust port 104 and an insertion port 106 are provided on the right side surface (+X side surface) of the imaging device body 102. Air that has become hot inside the body is exhausted from the exhaust port 104 by a forced air-cooling mechanism using a cooling fan 113 (Fig. 2(a)), which will be described later. When mounting a recording medium 401 (recording medium) in a media slot 118 (see Fig. 3), which will be described later, the recording medium 401 is inserted from the insertion port 106.

[0014] As shown in Fig. 1(b), an intake port 105 is provided on the bottom surface (-Y side surface) of the imaging device body 102. Therefore, the intake port 105 and the exhaust port 104 are provided on different surfaces of the imaging device body 102. The insertion port 106 is provided on the right side surface, which is the same surface as the surface on which the exhaust port 104 is arranged in the imaging device body 102 (Fig. 1(a)).

[0015] Cool air is drawn into the main body from the air intake 105 by a forced air-cooling mechanism using a cooling fan 113 (FIGS. 2(a) and (b)). A display unit 107 on which the captured image can be checked is mounted on the rear surface (-Z side surface) of the imaging device main body 102. A grip unit 120 is disposed on the left side of the imaging device main body 102 for the photographer to grip the imaging device main body 102 when using the imaging device 100.

[0016] The internal components of the imaging device 100 will be described with reference to Figures 2 and 3. Figures 2(a) and 2(b) are respectively a rear perspective view and a front perspective view of the internal components of the imaging device 100. Figure 3 is an exploded rear perspective view of the internal components of the imaging device 100. In Figures 2 and 3, illustrations of components other than the main components are omitted.

[0017] As shown in FIGS. 2 and 3, the interior of the imaging device 100 mainly comprises a control circuit board 110, a first duct 111, a second duct 112, a cooling fan 113, a battery 114, an imaging element board 115, and an imaging element 116.

[0018] The control circuit board 110 is a control board that controls the entire imaging device 100. The control circuit board 110 is mounted with elements 117 (117a, 117b), both of which are heat sources, and a media slot 118. The media slot 118 is a storage section that removably stores a recording medium 401, which is an example of a recording medium for recording data, etc. The elements 117a and 117b are examples of heat sources other than the storage section.

[0019] 3, the first duct 111 includes a first duct intake section 111a and a first duct exhaust section 111b. The second duct 112 includes a second duct intake section 112a and a second duct exhaust section 112b. The first duct 111 is connected to the intake side (+Z side) of the cooling fan 113, and the second duct 112 is connected to the exhaust side (+X side) of the cooling fan 113.

[0020] The cooling fan 113 is a so-called centrifugal fan that is configured to suck in air from a surface direction and expel it in a centrifugal (side) direction. The imaging device 100 takes in air (outside air) from an intake port 105 (FIG. 1(b)) by the rotation of the cooling fan 113, and exhausts the air from an exhaust port 104 (FIG. 1(a)) via the cooling fan 113 to dissipate heat.

[0021] A “heat dissipation duct” that cools the inside of the imaging device 100 is composed of a first duct 111 , a second duct 112 and a cooling fan 113 .

[0022] The heat dissipation structure of the imaging device 100 will be described with reference to Figures 4 and 5. Figure 4(a) is a bottom view of the imaging device 100. Figure 4(b) is a cross-sectional view taken along line AA in Figure 4(a). Figure 5(a) is a rear view of the imaging device 100. Figure 5(b) is a cross-sectional view taken along line BB in Figure 5(a).

[0023] As shown in Fig. 5(b), the control circuit board 110, the imaging element board 115, and the imaging element 116 are arranged substantially perpendicular to the optical axis direction. Various operation buttons (not shown) for performing various setting operations and release operations are provided on the top and back surfaces of the grip part 120 (Fig. 5(b)). A battery 114 that supplies power to the imaging device 100 is arranged inside the grip part 120. A part of the -X side of the control circuit board 110 is located on the back side of the battery 114 inside the grip part 120. The length 120a of the grip part 120 in the optical axis direction is determined in consideration of the balance between gripping ability and operability.

[0024] By arranging the first duct 111, the second duct 112 and the cooling fan 113 that constitute the heat dissipation duct at a position away from the grip portion 120 when viewed from the optical axis direction, the length 120a of the grip portion 120 in the optical axis direction is prevented from becoming too long.

[0025] The flow path inside the imaging device main body 102 will be described. The first duct 111, the second duct 112, and the cooling fan 113 are arranged substantially parallel to the control circuit board 110 on the rear side (-Z side) of the control circuit board 110 (FIG. 5(b)). The intake port 105 and the first duct intake section 111a are connected (FIG. 4(b)), and the exhaust port 104 (FIG. 1(a)) and the second duct exhaust section 112b (FIG. 3) are connected.

[0026] By the rotation of the cooling fan 113, outside air is taken in from the intake port 105 and the first duct intake section 111a, and the air flows in the first duct 111 in the direction of the arrow F1 (+Y direction) (FIG. 4(b)). Then, as shown in FIG. 5(b), the air passes through the first duct 111 in the direction of the arrow F2 (-Z direction), and is then sucked into the cooling fan 113 from the first duct exhaust section 111b. The air sucked in by the cooling fan 113 is introduced into the second duct 112 from the second duct intake section 112a (FIG. 3), and flows in the direction of the arrow F3 (+X direction) (FIG. 5(b)). Then, after passing through the second duct 112, the air is exhausted to the outside of the imaging device body 102 from the second duct exhaust section 112b (FIG. 3) and the exhaust port 104 (FIG. 1(a)).

[0027] Here, both the first duct 111 and the second duct 112 are made of metal members with high thermal conductivity. Note that fins (not shown) may be provided in the flow path of each duct to enhance heat exchange with the air. Also, the first duct 111 and the second duct 112 may be integrally constructed.

[0028] Also, the thickness of the second duct 112 in the Z direction is greater than the thickness of the first duct 111. Therefore, the second duct 112 has a larger flow path cross-sectional area (a cross-sectional area perpendicular to the flow path direction) than the first duct 111. Here, the flow path cross-sectional area of ​​the first duct 111 is the cross-sectional area perpendicular to the F1 direction. The flow path cross-sectional area of ​​the second duct 112 is the cross-sectional area perpendicular to the F3 direction. As a result, the flow speed of the second duct 112 is slower than that of the first duct 111, and the wind exhausted from the exhaust port 104 becomes weaker, thereby reducing discomfort felt by the user when the exhaust wind hits him.

[0029] 5(b), at least two elements (electronic components) that are heat sources are mounted on the control circuit board 110. The power consumption of the element 117a is higher than the power consumption of the element 117b. The element 117a is an element that requires a large amount of power, such as an image processing engine. Of the heat sources other than the recording medium 401, the element 117a may be the main heat source on the control circuit board 110.

[0030] The element 117a, which has a high need for heat dissipation, is disposed on a substantial projection of the first duct 111 in the optical axis direction (Z direction). Therefore, the element 117a overlaps with a part of the first duct 111 when viewed from the optical axis direction. This allows the heat of the element 117a to be efficiently transferred to the first duct 111 via the heat conductive member 119a. Here, the heat conductive member 119a is made of, for example, heat dissipation rubber with high thermal conductivity. On the other hand, the element 117b, which has a low need for heat dissipation, is disposed within the gripping portion 120. The element 117b overlaps with at least a part of the gripping portion 120 when viewed from the optical axis direction.

[0031] Moreover, the media slot 118 is disposed at the end of the control circuit board 110 opposite the grip part 120 (+X side) in the left-right direction. That is, the grip part 120 is disposed at the right end part (one end part) of the imaging device body 102, and the media slot 118 is disposed at the left end part (other end part) of the imaging device body 102.

[0032] The media slot 118 is thermally connected to the second duct 112 disposed on the rear side (-Z side) thereof via the heat conductive member 119b. As a result, heat generated by the recording medium 401 inserted into the media slot 118 is transferred to the second duct 112 via the media slot 118 and the heat conductive member 119b.

[0033] That is, heat from the high power consumption element 117a on the control circuit board 110 is transferred to the first duct 111, heat from the recording medium 401 is transferred to the second duct 112, and is dissipated outside the imaging device body 102 through the above-mentioned flow path.

[0034] According to this embodiment, the media slot 118 is mounted on the control circuit board 110 at a position that does not overlap the grip part 120 when viewed from the optical axis direction. The heat dissipation ducts (first duct 111, second duct 112, and cooling fan 113) are arranged at a position that does not overlap the grip part 120 when viewed from the optical axis direction, and the second duct 112 is thermally connected to the media slot 118. Since neither the media slot 118 nor the heat dissipation ducts overlap the grip part 120 when viewed from the optical axis direction, the length 120a of the grip part 120 in the optical axis direction is prevented from becoming long. In addition, since the media slot 118 and the second duct 112 are thermally connected, the heat of the media slot 118 and the recording medium 401 can be efficiently dissipated. Therefore, the recording medium (recording medium 401) can be efficiently cooled while preventing the device from becoming large.

[0035] Furthermore, the first duct 111 and the second duct 112 are parallel to the control circuit board 110, which contributes to suppressing the expansion of the imaging device 100 in the optical axis direction.

[0036] In particular, when viewed from the optical axis direction, the media slot 118 does not overlap with the first duct 111 but overlaps with a part of the second duct 112, and when viewed from the left-right direction (X direction), the media slot 118 does not overlap with the second duct 112 but overlaps with a part of the first duct 111. In other words, the media slot 118 is disposed in a space formed on the +X side and +Z side by the first duct 111 and the second duct 112. This allows the media slot 118 to be disposed by making effective use of the space, which contributes to the miniaturization of the imaging device 100.

[0037] Furthermore, since element 117a, which is a heat source other than media slot 118 mounted on control circuit board 110, is thermally connected to first duct 111, element 117a can also be efficiently cooled.

[0038] In addition, since the flow passage cross-sectional area of ​​the second duct 112 is larger than the flow passage cross-sectional area of ​​the first duct 111, discomfort caused by the exhaust air from the second duct 112 can be reduced.

[0039] Second embodiment The second embodiment of the present invention will be described with reference to Figures 6 to 9. In an imaging device 300 of this embodiment, parts not specifically mentioned are similar to those described as the first embodiment.

[0040] 6(a), (b) and (c) are a front perspective view, a rear perspective view and a right side view of the imaging device 300. Fig. 7 is a front perspective view of the internal components of the imaging device 300.

[0041] As shown in Fig. 6(a), the imaging device 300 is composed of an imaging device main body 302 and a lens 303. As shown in Fig. 7, inside the imaging device main body 302, there are arranged components including the main functions of the imaging device, such as a control circuit board 310, an imaging element 316, a power supply unit, a recording unit for recording images, and various operation units.

[0042] As shown in Fig. 6(b), a first air intake 305 and a second air intake 325 are provided on the bottom surface (-Y side surface) of the imaging device body 302. A forced air cooling mechanism using a cooling fan 313 (Fig. 7) draws cool outside air into the body from the first air intake 305 and the second air intake 325. A display unit 307 that allows the user to check the captured image is mounted on the rear surface (-Z side surface) of the imaging device body 302.

[0043] As shown in Fig. 6(c), an exhaust port 304, an insertion port 306, and a connection terminal 350 are provided on the right side surface 320 (+X side surface) of the imaging device main body 302. Two connection terminals 350 are provided side by side in the Y direction. Air that has become hot inside the main body is exhausted from the exhaust port 304 by a forced air-cooling mechanism using a cooling fan 313. When mounting a recording medium 401 in the media slot 318 (Fig. 7), the recording medium 401 is inserted from the insertion port 306.

[0044] The connection terminal 350 is a terminal for communicating with an external device, and a plurality of (for example, two) connection terminals are provided. The third intake port 321 is disposed between the two connection terminals 350 in the Y direction. When viewed from the +X side, the insertion port 306 is located between the exhaust port 304 and the third intake port 321. Therefore, in the optical axis direction, the media slot 318 is located between the exhaust port 304 and the third intake port 321.

[0045] The internal configuration of the imaging device 300 will be described with reference to Fig. 7 and Fig. 8. Fig. 8(a) and (b) are respectively a rear exploded perspective view and a front exploded perspective view showing the internal configuration of the imaging device 300. In Fig. 7 and Fig. 8, illustrations of components other than the main components are omitted.

[0046] 8(a) and 8(b), the imaging device 300 mainly includes a control circuit board 310, a first duct 311, a second duct 312, a cooling fan 313, a duct connection section 330, a battery 314 (FIG. 7), and an imaging section 309. The imaging section 309 includes an imaging element board 315, an imaging element 316, and a holding metal plate 357 (FIG. 7).

[0047] Imaging element 316 is mounted on imaging element board 315 substantially parallel to imaging element board 315, and imaging element board 315 is fixed to holding metal plate 357 with adhesive or the like. Control circuit board 310 is a control board that controls the entire imaging device 300. An element 317 and a media slot 318, both of which are heat sources, are mounted on control circuit board 310.

[0048] The first duct 311 includes a first duct exhaust section 311b and a connecting intake section 344. The second duct 312 includes a second duct intake section 312a. The first duct 311 is connected to the cooling fan 313 via the first duct exhaust section 311b, and the second duct 312 is connected to the cooling fan 313 via the second duct intake section 312a. The imaging device 300 takes in air from the first intake port 305 (FIG. 6(b)) by the rotation of the cooling fan 313, and exhausts the air from the exhaust port 304 (FIGS. 6(a) and (c)) via the cooling fan 313 to dissipate heat.

[0049] 8(a), the second duct 312 is disposed on the rear side (-Z side) of the media slot 318, which is a heat source. The media slot 318 and the second duct 312 are thermally connected via a thermally conductive first elastic member 354. As a result, heat generated from the recording medium 401 inserted into the media slot 318 is transferred to the second duct 312 via the media slot 318 and the first elastic member 354.

[0050] Further, a third duct 340 is disposed between the imaging unit 309 and the control circuit board 310 in the optical axis direction. That is, the third duct 340 is disposed on the opposite side (+Z side) of the control circuit board 310 from the side on which the media slot 318 is mounted. The third duct 340 forms a flow path inside by cooperation of a third duct main body 341 and a third duct cover member 342. The third duct main body 341 is thermally connected to the holding sheet metal 357 via a second elastic member 352 having thermal conductivity. On the other hand, the third duct cover member 342 is thermally connected to the control circuit board 310 via a third elastic member 353 having thermal conductivity.

[0051] The area of ​​the third duct 340 to which the third elastic member 353 is connected, and the area of ​​the third elastic member 353 and the mounting range of the media slot 318 on the control circuit board 310 at least partially overlap when viewed from the optical axis direction. That is, the media slot 318 and the third duct 340 at least partially overlap when viewed from the optical axis direction. The control circuit board 310 and the third duct 340 are thermally connected in the range where the media slot 318 and the third duct 340 overlap when viewed from the optical axis direction.

[0052] With this configuration, heat from the imaging unit 309 and the media slot 318 is transferred to the third duct 340, and the imaging unit 309 and the media slot 318 are cooled by the wind (outside air) passing through the third duct 340.

[0053] Further, the third duct body 341 has an extension portion 308. The extension portion 308 is a portion that extends in the +X direction, and is a portion of the third duct body 341 that does not form a flow path. A flexible cable 351 having a connection terminal 350 mounted thereon is fixed to the extension portion 308. The flexible cable 351 is electrically connected to the control circuit board 310.

[0054] The following describes the heat dissipation structure and air flow of the image capture device 100. A “heat dissipation duct” that cools the inside of the image capture device 100 is made up of a first duct 311, a second duct 312, and a cooling fan 313.

[0055] Fig. 9(a) is a bottom view of the imaging device 300. Fig. 9(b) is a cross-sectional view taken along line CC in Fig. 9(a). Fig. 9(c) is a schematic top view of the imaging device 300. In Fig. 9(c), the exterior is shown by dashed lines to explain the internal structure.

[0056] The air flows through the first duct 311 and the second duct 312 are the same as those in the first embodiment, and therefore will not be described. The following mainly describes the flow of outside air related to the cooling of the media slot 318 through the third duct 340.

[0057] 9(b) and (c), outside air 322 is supplied to the third duct 340 from a third intake port 321 (FIG. 6(c)) on the right side surface 320 of the imaging device body 302 and a second intake port 325 (FIG. 6(b)) on the bottom surface of the imaging device body 302. The third duct 340 is connected to a connection intake section 344 (FIG. 8(a)) of the first duct 311 via a duct connecting section 330 above the control circuit board 310.

[0058] The outside air 322 supplied from the third intake port 321 and the second intake port 325 cools the imaging unit 309 and the media slot 318 as it passes through the third duct 340 due to an airflow generated by the cooling fan 313. The air that has cooled these passes through the duct connecting portion 330, merges with the first duct 311, and is then discharged from the exhaust port 304 (FIGS. 6(a) and (c)). Thus, the duct connecting portion 330 provides a communication passage that allows the air taken into the third duct 340 to merge with the flow path in the first duct 311.

[0059] According to this embodiment, the media slot 318 is mounted on the control circuit board 310 at a position that does not overlap with the grip part 120 when viewed from the optical axis direction. The heat dissipation ducts (first duct 311, second duct 312, and cooling fan 313) are arranged at positions that do not overlap with the grip part 120 when viewed from the optical axis direction, and the second duct 312 is thermally connected to the media slot 118. Therefore, the same effect as the first embodiment can be achieved in terms of efficiently cooling the recording medium 401 while suppressing an increase in size.

[0060] Furthermore, when viewed from the optical axis direction, the media slot 318 and the third duct 340 at least partially overlap each other, and the control circuit board 310 and the third duct 340 are thermally connected within the range where the media slot 318 and the third duct 340 overlap. Therefore, heat from the recording medium 401 is efficiently transferred to the third duct 340 through the third elastic member 353. Furthermore, heat from the recording medium 401 is transferred to the second duct 312 through the first elastic member 354. Therefore, the recording medium 401 can be dissipated from both directions in the optical axis direction by the third duct 340 and the second duct 312, making it possible to cool the recording medium even more efficiently.

[0061] Moreover, the third duct 340 is located between the control circuit board 310 and the image sensor 316 in the optical axis direction, and is thermally connected to the image sensor 316. As a result, the third duct 340 has a function of cooling the control circuit board 310 or the image sensor 316 and a function of cooling the recording medium 401, which contributes to suppressing an increase in size without increasing the number of components.

[0062] Furthermore, since the connection terminal 350 for connecting an external device is fixed to the extension portion 308 which is a portion of the third duct 340 that does not form a flow path, a rise in temperature of the connection terminal 350 can be avoided.

[0063] (Third embodiment) The third embodiment of the present invention will be described with reference to Figures 10 to 16. In the imaging device 100 of this embodiment, parts not specifically mentioned are similar to those described as the first embodiment. For example, the air flow in the first duct 111 is similar to that in the first embodiment.

[0064] 10 is a rear perspective view showing the cooling structure for the recording medium 401. The recording medium 401, which is a heat source, is inserted into a media slot 402 mounted on the control circuit board 110. Heat generated by the recording medium 401 is transferred to the second duct 403 via the media slot 402. As in the first embodiment, air generated by the cooling fan 113 flows into the second duct 403. This allows the heat of the recording medium 401 transferred to the second duct 403 to be discharged to the outside of the imaging device 100.

[0065] 11(a) and (b) are respectively a rear exploded perspective view and a front exploded perspective view showing the cooling structure of the recording medium 401. The second duct 403 includes a duct base member 405, a film member 406, and a duct case member 407. The duct base member 405 is formed of plastic or metal die casting. A frame opening 408 is formed in the duct base member 405 on the optical axis projection of the recording medium 401. In addition, the -Z side surface around the frame opening 408 of the duct base member 405 serves as an attachment surface 409.

[0066] The film member 406 is formed of a thin, highly flexible film material such as polyethylene, polypropylene, or polyvinyl chloride. The film member 406 may be made of a material in which fibrous raw materials are laminated, or a laminated graphite sheet. The film member 406 has an adhesive layer 410 made of a double-sided tape, adhesive, or the like. The adhesive layer 410 is attached to an attachment surface 409, whereby the frame opening 408 is sealed by the film member 406.

[0067] Next, the assembly sequence of the cooling structure will be described. First, the worker attaches the control circuit board 110 to the fastening parts 411a and 411b of the duct base member 405 using the screws 412a and 412b. Next, the worker attaches the adhesive layer 410 of the film member 406 to the attachment surface 409 of the duct base member 405. At this time, the film member 406 and the media slot 402 come into contact with each other. The detailed positional relationship between the film member 406 and the media slot 402 will be described later. Next, the worker covers the duct base member 405 with the duct case member 407. As a result, a sealed flow path is formed in the second duct 403. The duct case member 407 and the duct base member 405 form the frame part of the second duct 403.

[0068] FIG. 12 is a perspective view showing the media slot 402 and the recording medium 401. The detailed shape of the media slot 402 will be described. In this embodiment, the media slot 402 has an arm 413 for removing static electricity from the recording medium 401 and removing backlash. The arm 413 is bent in the +Z direction and comes into contact with the inserted recording medium 401. A storage section opening 414 is also formed around the arm 413. That is, the media slot 402 has two arms 413 cut and raised inward at the storage section opening 414, and these arms 413 come into contact with the recording medium 401 stored in the media slot 402. The media slot 402 also has a step 415 on the side (-Z side) facing the second duct 403 in the optical axis direction.

[0069] Next, the manner in which the media slot 402 and the film member 406 come into contact with each other will be described with reference to FIGS.

[0070] Fig. 13 is a cross section taken along line DD in Fig. 10. Fig. 14 is an enlarged view of part F in Fig. 13. Fig. 15 is an enlarged view of part G in Fig. 13.

[0071] The second duct 403 is configured from the frame portion (duct case member 407 and duct base member 405) and the film member 406. The film member 406 is a heat transfer member that is more flexible than the frame portion.

[0072] Of the film member 406, the portion exposed into the duct from frame opening 408 (FIG. 11(a)) of duct base member 405 contacts media slot 402 over substantially the entire area. Because film member 406 is thin and highly flexible, it is possible to transfer heat from recording media 401 into second duct 403 without applying excessive load to media slot 402 and recording media 401.

[0073] 14, media slot 402 has a step 415. Because film member 406 is highly flexible and cooling fan 113 creates a positive pressure inside second duct 403, film member 406 and media slot 402 can come into contact on the left and right of step 415. By increasing the contact area between film member 406 and second duct 403, the heat dissipation efficiency of recording media 401 is improved.

[0074] 15, the tip of arm 413 abuts against recording medium 401. Storage opening 414 of media slot 402 is sealed with film member 406, thereby ensuring airtightness of the flow path of second duct 403.

[0075] Next, the positional relationship in the Z direction between the control circuit board 110, the media slot 402, and the second duct 403 will be described with reference to Fig. 16. Fig. 16 is a cross-sectional view taken along the line EE in Fig. 10.

[0076] 16, in the Z direction, part of the upper end of the media slot 402 is inside the frame opening 408 of the duct base member 405. In other words, in the optical axis direction, part of the media slot 402 fits inside the frame opening 408. By arranging the media slot 402 so that it fits into the frame opening 408 by the thickness H of the duct base member 405, it is possible to reduce the thickness J from the control circuit board 110 to the second duct 403 without reducing the flow path width I.

[0077] Furthermore, in this embodiment, the adhesive force and the positive pressure generated by the cooling fan 113 ensure close contact between the film member 406 and the media slot 402. However, instead of or in addition to adhesion, an adhesive member may be provided between the film member 406 and the media slot 402 to ensure close contact.

[0078] According to this embodiment, the media slot 402 is mounted on the control circuit board 110 at a position that does not overlap with the grip part 120 when viewed from the optical axis direction. The heat dissipation ducts (first duct 111, second duct 403, and cooling fan 113) are arranged at positions that do not overlap with the grip part 120 when viewed from the optical axis direction, and the second duct 403 is thermally connected to the media slot 402. Therefore, the same effect as the first embodiment can be achieved in terms of efficiently cooling the recording medium 401 while suppressing an increase in size.

[0079] Moreover, the second duct 403 is composed of a frame portion (duct case member 407 and duct base member 405) and a film member 406, and the film member 406 is thermally connected to the media slot 402. This allows the media slot 402 to dissipate heat using not only the first duct 111 but also the second duct 403, thereby improving the cooling effect of the recording medium 401. Furthermore, since the film member 406 is more flexible than the frame portion, the thermal connection between the second duct 403 and the recording medium 401 becomes stronger, and the cooling effect can be further improved.

[0080] Moreover, film member 406 is configured in a sheet shape and is arranged so as to block frame opening 408 formed in the frame portion from the inside. Storage section opening 414 of media slot 402 is also covered with film member 406. Furthermore, film member 406 is fixed to the inner surface of the frame portion by adhesion or bonding, and since the inside of second duct 403 is at a positive pressure, the adhesion between film member 406 and second duct 403 is high even if step portion 415 is present. As a result, a decrease in cooling efficiency can be suppressed.

[0081] In addition, in the media slot 402, two arms 413 cut and raised inward at the storage opening 414 abut against the recording medium 401, so that the holding of the recording medium 401 and the thermal connection with the recording medium 401 can be strengthened.

[0082] Furthermore, since a portion of the media slot 402 is recessed within the frame opening 408 in the optical axis direction, expansion in the optical axis direction can be suppressed.

[0083] (Fourth embodiment) A fourth embodiment of the present invention and its modified examples will be described with reference to Figures 17 to 24. In an imaging device 700 of this embodiment, parts that are not particularly mentioned are similar to those described as the first embodiment.

[0084] 17(a) and (b) are respectively a front perspective view and a rear perspective view of an imaging device 700. The imaging device 700 is composed of an imaging device body 500 and a lens 504. The imaging device body 500 is provided with a media cover 551 and a terminal cover 554.

[0085] Figures 18(a) and (b) are front perspective views of the imaging device 700. Figures 18(a) and (b) show a state in which the media cover 551 and the terminal cover 554 are open.

[0086] The imaging device body 500 has a gripping portion 503, an exhaust port 501, an intake port 502, and a media slot 519. The exhaust port 501 and the intake port 502 are respectively arranged at the end of the +X side of the imaging device body 500 and at the bottom. The media slot 519 is arranged at the end of the +X side of the imaging device body 500. The media slot 519 has a media insertion portion 550 which is a media insertion portion for inserting a recording medium 520. The media insertion portion 550 is arranged on the +Z side of the exhaust port 501 at the end of the +X side of the imaging device body 500 (FIG. 18(a)). Therefore, the exhaust port 501 and the media insertion portion 550 are arranged at the end of the imaging device body 500 on the opposite side (+X side) from the side where the gripping portion 503 is arranged in the left-right direction.

[0087] A media cover 551 covers the media insertion portion 550. The media cover 551 is opened and closed by rotating about a media cover rotation shaft 552 (FIG. 21) relative to the imaging device main body 500, and transitions the media insertion portion 550 between a closed state and an exposed state.

[0088] The imaging device body 500 is provided with a detection switch (not shown) that detects the closed state of the media cover 551. When the recording medium 520 is inserted into the media slot 519 and it is detected that the media cover 551 is closed, the control circuit board 517 becomes able to access the recording medium 520.

[0089] The terminal cover 554 is disposed on the upper surface of the imaging device main body 500, and is opened and closed by rotating about a terminal cover rotation shaft 555 (FIG. 21) described later, transitioning the connection terminal 553 between a closed state and an exposed state. With the terminal cover 554 in an open state, a connection plug 564 can be attached to the connection terminal 553. FIG. 18(b) shows a state in which the connection plug 564 is attached and the recording medium 520 protrudes from the media slot 519.

[0090] The display unit 560 (FIG. 17(b)) displays captured images and captured information. As shown in FIGS. 17(a) and 17(b), the pivot support 561 is disposed at the end (the end on the +X side) of the imaging device body 500 opposite the grip unit 503 in the X direction. The pivot support 561 supports the display unit 560 rotatably in two directions relative to the imaging device body 500. First, the pivot support 561 supports the display unit 560 rotatably by a predetermined angle around a rotation axis 562 parallel to the Y direction. The pivot support 561 also supports the display unit 560 rotatably by a predetermined angle around a rotation axis 563 parallel to the X direction.

[0091] Fig. 19(a) and (b) are respectively a schematic horizontal cross-sectional view and a ZY cross-sectional view of the imaging device body 500. Fig. 20(a) is a schematic ZY cross-sectional view of the imaging device body 500 taken along a cross section passing through the connection terminal 553. Fig. 20(b) is an enlarged view of part B in Fig. 20(a). Fig. 21 is a front perspective view showing the internal configuration of the imaging device body 500. In Figs. 19 to 21, illustrations of components other than the main components are omitted.

[0092] Fig. 22(a) is a front view showing the internal configuration of the imaging device main body 500. Fig. 22(b) is a cross-sectional view taken along line FF in Fig. 22(a). Fig. 22(c) is an enlarged view of part C in Fig. 22(b).

[0093] The main components inside the imaging device will be described with reference to Figures 19 to 22. The heat dissipation duct in this embodiment is made up of a first duct 511, a second duct 512, and a cooling fan 513 (Figure 19(a)).

[0094] 21, control circuit board 517 is disposed on the +Z side of the heat dissipation duct. Imaging element 523 is mounted on the +Z side of control circuit board 517. Element 518 (FIG. 19(a)) is mounted on the -Z side of control circuit board 517. Heat from element 518 is conducted to first duct 511.

[0095] As shown in FIG. 19(a), a media slot 519 is mounted on the surface (-Z side) of the control circuit board 517 facing the second duct 512. In this embodiment, two media slots 519 are mounted side by side in the Y direction (FIG. 20(a)). Between the media slot 519 and the second duct 512 in the Z direction, a thermally conductive rubber 521 is disposed in contact with both. Heat from the recording medium 520 is transmitted to the second duct 512 via the media slot 519 and the thermally conductive rubber 521. The battery 522 is disposed in the grip portion 503.

[0096] Connection terminal 553 with an insertion portion facing upward is mounted on the end of control circuit board 517 on the +X side and +Y side (FIGS. 21 and 22(c)). Note that connection terminal 553 is mounted on control circuit board 517, but is not limited to this, and may be mounted on another circuit board arranged in parallel close to control circuit board 517.

[0097] Connection terminal 553 is located on the opposite side (+Z side) of control circuit board 517 from the side on which media slot 519 is mounted in the optical axis direction (FIGS. 20(a) and (b)). That is, media slot 519 and connection terminal 553 are located on different faces of control circuit board 517 and are close to each other in the Z direction. However, the insertion direction of media slot 519 is the X direction, and the insertion direction of connection terminal 553 is the Y direction, so that on the external surface, the insertion portions of the two are not close to each other.

[0098] As shown in FIGS. 19(a) and 19(b), the first duct 511 forms a space on the +Z side of the fan intake 514 of the cooling fan 513, and is connected to the intake 502 (FIGS. 17(b) and 19(b)). The second duct 512 forms a space extended in the +X direction from the fan exhaust 515 of the cooling fan 513, and is connected to the exhaust 501 (FIGS. 17(a) and 19(a)). The width of the flow path formed by the second duct 512 is the width of the fan exhaust 515 in the Z direction. Therefore, as a flow path of the heat dissipation duct, a forced air-cooling flow path is formed that is connected from the intake 502 of the imaging device main body 500 to the first duct 511, the cooling fan 513, the second duct 512, and the exhaust 501.

[0099] Shooting operation generates heat in elements 518 on the control circuit board 517 and in the recording medium 520. This activates the cooling fan 513, which draws in outside air from the intake port 502 (FIG. 19(b)). The air warmed by the heat transmitted to the first duct 511 and the second duct 512 is then exhausted from the exhaust port 501 (FIG. 19(a)).

[0100] As shown in FIGS. 21 and 22( c ), the media cover 551 is rotatable about a media cover rotation shaft 552 , and the terminal cover 554 is rotatable about a terminal cover rotation shaft 555 .

[0101] 22(c), the end face on the +Z side of the second duct 512 is recessed with respect to the end face on the +Z side of the first duct 511. Therefore, the second duct 512 has a step portion 516 recessed in the optical axis direction (-Z side) with respect to the first duct 511. A media cover 551 and a media cover rotation shaft 552 which is a rotation mechanism of the media cover 551 are arranged in this step portion 516. Furthermore, a terminal cover 554 and a terminal cover rotation shaft 555 which is a rotation mechanism of the terminal cover 554 are arranged in the step portion 516. This allows the space of the step portion 516 to be effectively utilized, thereby suppressing an increase in the thickness of the main body.

[0102] Since the media cover 551 and the terminal cover 554 are disposed on different sides of the imaging device body 500, the covers do not interfere with each other when opening and closing. Even when the connection plug 564 is attached to the connection terminal 553, the connection plug 564 does not get in the way when inserting and removing the recording medium 520 into and from the media slot 519.

[0103] Moreover, when an accessory device (not shown) is attached to the upper surface of imaging device main body 500 and the accessory device is connected to connection terminal 553, the attachment state of the accessory device can be easily visually confirmed. Furthermore, when holding imaging device main body 500, a user usually holds gripping portion 503 and the end portion opposite gripping portion 503, so that connection plug 564 extending upward from imaging device main body 500 does not get in the way of holding the body.

[0104] 23(a) and (b) are front perspective views of the imaging device 700 showing the operation of the display unit 560. Fig. 23(a) shows a state in which the display unit 560 is rotated 180° in the open direction around a rotation axis 562 (Fig. 17(b)) relative to the imaging device main body 500. Fig. 23(b) shows a state in which the display unit 560 is rotated 90° around a rotation axis 563 (Fig. 17(b)) from the state shown in Fig. 23(a).

[0105] When the display unit 560 is rotated, the display unit 560 rotates within a range close to the media cover 551. However, since the imaging device main body 500 is enabled to operate on the condition that the media cover 551 is detected to be closed during shooting, the display unit 560 and the media cover 551 do not usually interfere with each other during shooting. Also, since the connection terminal 553 is disposed on the top surface of the main body (FIG. 18(a)), even if the connection plug 564 is attached, the display unit 560 and the connection plug 564 do not interfere with each other.

[0106] According to this embodiment, the media slot 519 is mounted on the control circuit board 517 at a position that does not overlap with the grip part 503 when viewed from the optical axis direction. The heat dissipation ducts (first duct 511, second duct 512, and cooling fan 513) are arranged at positions that do not overlap with the grip part 503 when viewed from the optical axis direction, and the second duct 512 is thermally connected to the media slot 519. Therefore, the same effect as in the first embodiment can be achieved in terms of efficiently cooling the recording medium 520 while suppressing an increase in size.

[0107] Furthermore, since the connection terminal 553 is disposed at a position that does not overlap with either the exhaust port 501 or the medium insertion portion 550 when viewed from the optical axis direction, it is possible to suppress expansion in the optical axis direction.

[0108] Further, a media cover 551, a media cover rotation shaft 552, a terminal cover 554, and a terminal cover rotation shaft 555 are arranged in a stepped portion 516 formed by recessing the second duct 512 in the optical axis direction relative to the first duct 511. This allows the space of the stepped portion 516 to be effectively utilized, thereby suppressing the enlargement of the device.

[0109] A modified example of this embodiment will be described with reference to Figures 24(a) and (b). Figures 24(a) and (b) are respectively a front perspective view and a rear perspective view of the upper right end portion of the modified imaging device main body 500. In this modified example, a terminal cover 557 is used instead of the terminal cover 554. Figures 24(a) and (b) show the terminal cover 557 in a closed state, and Figure 24(b) shows the terminal cover 557 in an open state and a connection plug 564 connected to the connection terminal 553.

[0110] Terminal cover 557 is prevented from coming off from imaging device body 500 by flexible connecting portion 556. By pulling terminal cover 557 out from imaging device body 500 in the +Y direction and rotating it about the Y axis, connection terminal 553 is exposed and connection plug 564 can be attached. Even in this configuration, flexible connecting portion 556 is disposed at step portion 516, so that an increase in the thickness of imaging device body 500 in the Z direction is suppressed.

[0111] In each embodiment, the term "substantially" does not mean to exclude "completely." For example, "substantially the entire area," "substantially on projection," "substantially parallel," and "substantially perpendicular" are intended to include the complete "entire area," "on projection," "parallel," and "perpendicular," respectively.
