Description

[Technical field]

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

[0002] In recent imaging devices, the improvement in image quality has led to an increase in heat generation in signal processing units such as the imaging unit, making cooling inside the device important. Patent Document 1 discloses an imaging device with a heat dissipation structure that forcibly cools the inside of the imaging device.

[0003] The imaging device in Patent Document 1 has a forced air-cooling passage built into the grip section that is held by the photographer, and outside air is drawn in through an air intake on the front side of the device, passes through the forced air-cooling passage for heat exchange, and is then exhausted from an exhaust port on the rear side of the device, thereby cooling the main heat source inside the device.

[0004] [Patent Document 1] JP 2019-9553 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the future, as the writing bit rate increases to achieve higher image quality, there is concern that the recording media will generate more heat, and therefore the recording media will also need to be cooled efficiently. However, Patent Document 1 does not mention cooling the recording media contained in the grip section.

[0006] The cooling structure of Patent Document 1 is suitable for cases where the main circuit board for controlling the entire imaging device is arranged parallel to the optical axis. However, it is not easy to apply the cooling structure to cases where the main circuit board is arranged perpendicular to the optical axis, as in many grip-integrated interchangeable lens imaging devices.

[0007] An object of the present invention is to efficiently cool a recording medium. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the imaging device of the present invention is characterized in having a protrusion protruding toward the subject in the optical axis direction, a grip section provided at the end of the device body, a media board having a media storage section for storing recording media mounted thereon and arranged on the opposite side of the protrusion from the subject in the optical axis direction, a main circuit board arranged approximately perpendicular to the optical axis, a cooling duct including a first extension section extending within the grip section in a direction intersecting the optical axis direction, and thermally connected to the media board and the main circuit board, and an air-cooled fan that introduces air into the cooling duct. Effect of the Invention

[0009] According to the present invention, the recording medium can be cooled efficiently. [Brief description of the drawings]

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] (First embodiment) 1(a) and (b) are perspective views of an imaging device according to a first embodiment of the present invention. The imaging device 1 is a camera in which a lens 101 and a battery 105 are detachably attached to a device body 100. The optical axis of the imaging device 1 is designated as C0.

[0013] FIG. 1(a) shows a state in which a lens 101 and a battery 105 are attached to a device body 100, and FIG. 1(b) shows a state in which the lens 101 and the battery 105 are removed from the device body 100.

[0014] Hereinafter, the directions of each part will be referred to based on the X, Y, and Z coordinate axes shown in FIG. 1 and the like. For convenience, the subject side in the direction parallel to the optical axis C0 will be referred to as the front. The optical axis C0 is parallel to the Z direction. For example, in FIG. 1(a) and (b), the +Y direction / -Y direction is upward / downward, and the +Z direction / -Z direction is forward / backward. The +X direction / -X direction is rightward / leftward when viewed from the subject side. Therefore, FIG. 1(a) and (b) are respectively a front perspective view and a rear perspective view of the imaging device 1.

[0015] 2(a) and (b) are rear perspective views of the imaging device 1. A media lid 150 is attached to the device body 100 so as to be able to open and close. Fig. 2(a) shows a state in which the media lid 150 is closed relative to the device body 100, and Fig. 2(b) shows a state in which the media lid 150 is open relative to the device body 100.

[0016] 1(a) and (b), a power switch 103 for turning the power on and off and a capture button 104 for starting and stopping still image capture and video capture are disposed on the top of the device body 100. A battery 105 for supplying power to operate the imaging device 1 is housed detachably in the bottom of the device body 100. A grip section 110 for the photographer to hold is provided on the end of the device body 100 on the -X side. The grip section 110 has a protruding section 111 that protrudes toward the subject side (forward). The protruding section 111 is a portion for the user to hook his / her finger on.

[0017] Further, an air intake 1341 is arranged on the front side of the device body 100, which draws (introduces) cool outside air into the device body 100 by a heat dissipation structure H (FIG. 4) using a cooling fan 131, which will be described later. At least a part of the air intake 1341 is arranged so as to hang over the protruding part 111 of the grip part 110. An exhaust port 135 is arranged on the end part on the +X side opposite the grip part 110 in the X direction (left-right direction) to exhaust hot air inside the device body 100 to the outside.

[0018] As shown in FIG. 2(a), a display panel 106 on which a captured image is displayed and an operation unit 102 including buttons and dials for the photographer to change the capture settings are disposed on the rear side of the device body 100. A media cover 150 is disposed on the -X side of the device body 100. The recording medium 141 is a recording medium for storing captured data. As shown in FIG. 2(b), opening the media cover 150 opens a media insertion opening 143a (insertion opening) in a media slot 143 (media storage section) described later, allowing the recording medium 141 to be inserted and removed from the media slot 143. The media cover 150 is an opening / closing cover that opens and closes the media insertion opening 143a, and protects the recording medium 141 stored in the media slot 143.

[0019] An outline of the internal structure of the imaging device 1 will be described with reference to Figures 3 and 4. Figure 3 is a rear view of the imaging device 1. Figure 4 is a cross-sectional view taken along line AA in Figure 3, showing an XZ cross section including the optical axis C0.

[0020] 4, an imaging element board 161, a main circuit board 170, a media board 140, etc. are arranged inside the device body 100. An imaging element 160 that converts light entering through the lens 101 into an electrical signal is mounted on the imaging element board 161. The main circuit board 170 controls the entire imaging device 1. A media slot 143 that accommodates a recording medium 141 is mounted on the media board 140.

[0021] The imaging element substrate 161 is fixed to a metallic substrate holding member 162. By adjusting the mounting position of the substrate holding member 162, the distance between the lens attachment portion to which the lens 101 is attached and the imaging element 160 can be adjusted to a desired distance.

[0022] Inside the device body 100, the main circuit board 170 is disposed on the rear side of the imaging element board 161, perpendicular to the optical axis C0. The media slot 143 is disposed behind the protrusion 111. That is, the media board 140 is disposed on the opposite side (-Z side) from the subject side in the direction of the optical axis C0 with respect to the protrusion 111. This is in consideration of the layout of the components inside the device body 100 and the operability of inserting and removing the recording media 141.

[0023] The heat dissipation structure H included in the device body 100 will be described using Figures 5 and 6 in addition to Figure 4. Figures 5(a), (b), 6(a), and (b) are a front perspective view, an exploded front perspective view, a rear perspective view, and an exploded rear perspective view of the heat dissipation structure H and its periphery inside the device body 100, respectively.

[0024] During shooting operation of the imaging device 1, the electric elements mounted on the imaging element board 161 and the main circuit board 170 consume power and generate heat. Furthermore, the recording medium 141 also generates heat as the shooting data is recorded. In particular, when shooting high-resolution, high-bit-rate video, the power consumption of each electric element increases and the power consumption of the recording medium 141 also increases, so that each part is likely to become hot. For this reason, a heat dissipation structure H is provided inside the device body 100 to prevent performance degradation of the electric elements and the recording medium 141 and a rise in temperature of the exterior surface.

[0025] The heat dissipation structure H includes a cooling duct 120. The cooling duct 120 is thermally connected to the media substrate 140 and the main circuit substrate 170. The cooling duct 120 includes a first extension portion D1 and a second extension portion D2. The first extension portion D1 is a portion that is extended in a direction intersecting the optical axis C0 direction within the grip portion 110 (inside the grip portion). The extension direction of the first extension portion D1 may be parallel to the optical axis C0 direction. The second extension portion D2 is a portion that is extended along the main circuit substrate 170 and is approximately perpendicular to the optical axis C0 direction. When viewed from the +Y side, the cooling duct 120 is approximately L-shaped as a whole. This forms a long air flow path, enlarging the surface area, and improving the amount of heat dissipation of the cooling duct 120. Furthermore, the heat transfer path from the heat generating portion inside the device main body 100 to the cooling duct 120 is simplified.

[0026] In particular, the layout is such that the main circuit board 170 is perpendicular to the optical axis C0, and the media board 140 is disposed at the rear or behind the grip part 110. This layout is advantageous in that it makes it easy to arrange the cooling duct 120 close to the main circuit board 170 and the media board 140, which require heat dissipation. In the first extension part D1, air flows mainly in a direction intersecting the optical axis C0 direction, and in the second extension part D2, air flows mainly in a direction along the main circuit board 170 (+X direction).

[0027] 6(b) is a portion on the main circuit board 170 where an electric element that generates heat is mounted. The heat conducting member 172 is disposed so as to be sandwiched between the main circuit board 170 and the cooling duct 120 in the direction of the optical axis C0. The heat conducting member 172 contacts the heat generating member 171 on the front side and contacts the cooling duct 120 on the rear side, thereby efficiently transferring heat from the main circuit board 170 to the cooling duct 120.

[0028] The thermally conductive member 142 is disposed so as to be sandwiched between the media substrate 140 and the cooling duct 120 in the optical axis direction. The thermally conductive member 142 contacts the cooling duct 120 on the front side and contacts the media substrate 140 on the rear side, thereby efficiently transferring heat from the recording medium 141 to the cooling duct 120.

[0029] As shown in Figs. 4 and 5(b), a power supply circuit board 180 is disposed inside the grip portion 110 as a circuit board different from both the main circuit board 170 and the media board 140. The power supply circuit board 180 is thermally connected to the first extension portion D1 along the first extension portion D1. A heat transfer path from the heat generating portion 181 of the power supply circuit board 180 to the cooling duct 120 is simply formed via the heat conductive member 182. This allows the power supply circuit board 180 disposed inside the grip portion 110 to be efficiently cooled.

[0030] Cooling duct 120 is made of a metal with high thermal conductivity such as aluminum. Exhaust duct 133 is connected to cooling fan 131, which is an air-cooling fan. Cooling fan 131 introduces air into cooling duct 120. Outside air taken in by cooling fan 131 from intake port 1341 (FIG. 4) becomes air flowing inside cooling duct 120. The air exchanges heat with cooling duct 120, which has become hot due to heat transfer from a heat generating part, and the air increases in temperature, and is then discharged to the outside from exhaust port 135 (FIG. 4) via exhaust duct 133.

[0031] In addition, an elastic member 123 is sandwiched between the cooling duct 120 and the cooling fan 131. This prevents air circulating inside the cooling duct 120 from leaking and prevents foreign matter such as dust from entering the inside of the device main body 100.

[0032] Next, the heat transfer path from the recording medium 141 to the cooling duct will be described with reference to FIGS.

[0033] Figures 7(a) to (c) are rear perspective cross-sectional views of the -X side end in the cross section along line AA in Figure 3. These figures show a series of operations in which, with recording medium 141 inserted into media slot 143 of device body 100, media cover 150 moves from an open state, through a closed state, to a locked state.

[0034] 7(a) and (b) respectively show an open state and a closed state of the media lid 150. Fig. 7(c) shows a state in which the media lid 150 is closed and locked relative to the device main body 100.

[0035] The heat of the recording medium 141 is dissipated by being transferred to the cooling duct 120 via the media board 140 (FIG. 4) on which the media slot 143 is mounted. If a direct heat transfer path could be configured from the recording medium 141 to the cooling duct 120, the heat dissipation effect could be further improved. However, since the recording medium 141 is inserted into and removed from the device body 100, it is necessary to configure the heat transfer path so as to minimize the impact on the operability of insertion and removal, and the impact on durability when repeated insertion and removal are performed. Therefore, in this embodiment, a method is adopted in which the heat transfer path from the recording medium 141 to the cooling duct 120 is configured to pass through the media lid 150.

[0036] 7(a), when the media lid 150 is open, the media insertion opening 143a of the media slot 143 is open, allowing insertion / removal of the recording medium 141. In this state, the duct side surface 121, which is a part of the side surface on the -X side of the cooling duct 120, is exposed.

[0037] The media cover 150 is supported on the device body 100 so as to be rotatable about a rotation shaft 151. As shown in Fig. 7(b), the media cover 150 rotates about the rotation shaft 151 to close, thereby protecting the recording medium 141. Then, the closed media cover 150 is slid together with the rotation shaft 151 in the Z direction, and is locked to the device body 100 by a locking mechanism (not shown) (Fig. 7(c)). In this locked state, the media cover 150 does not rotate in the open direction.

[0038] As shown in Fig. 7(c), in the locked state, the contact portion 152 of the media lid 150 contacts the back surface of the recording medium 141, and the contact portion 153 contacts the duct side surface 121 (Fig. 7(a)) of the cooling duct 120. This forms a heat transfer path from the recording medium 141 to the cooling duct 120 via the media lid 150. At least the contact portions 152 and 153 of the media lid 150 may be made of a heat conductive material.

[0039] According to this embodiment, the cooling duct 120 includes a first extension portion D1 extending in a direction intersecting the optical axis direction, and is thermally connected to the media board 140 and the main circuit board 170. By arranging the first extension portion D1 inside the grip portion 110, the first extension portion D1 can be arranged in the vicinity of the media board 140, and the heat dissipation efficiency of the recording medium 141 is improved. In addition, the cooling duct 120 has a substantially L-shape, which enhances heat dissipation performance and facilitates heat transfer from heat-generating components. Therefore, the recording medium 141 can be efficiently cooled.

[0040] In particular, even in a configuration in which the main circuit board 170 is disposed substantially perpendicular to the optical axis C0 and the media board 140 is disposed rearward of the protrusion 111, a structure for cooling the recording medium 141 can be easily realized. Moreover, the cooling duct 120 that cools the main circuit board 170 can also be used to cool the recording medium 141, making it possible to reduce the complexity of the configuration.

[0041] Moreover, since at least a portion of the intake port 1341 is disposed in the protruding portion 111, cool air can be efficiently supplied to the first extension portion D1. From this viewpoint, the entire intake port 1341 may be disposed in the protruding portion 111. Furthermore, since the exhaust port 135 is disposed at the end opposite to the grip portion 110 in the left-right direction, a long path from the intake port 1341 to the exhaust port 135 can be ensured, which contributes to improved cooling efficiency.

[0042] Furthermore, when the media lid 150 is in the closed state, the contact portion 152 that is a part of the media lid 150 comes into contact with the recording medium 141 , so that heat from the recording medium 141 can be released through the media lid 150 .

[0043] In addition, when the media lid 150 is in the closed state, the abutment portion 153 , which is another part of the media lid 150 , contacts the duct side surface 121 of the cooling duct 120 , so that the heat of the air inside the cooling duct 120 can be released through the media lid 150 .

[0044] Second embodiment 8 and 9 are respectively a front perspective view and a rear perspective view of an imaging device according to a second embodiment of the present invention. This embodiment differs from the first embodiment mainly in the configurations of the media lid 150 and the cooling duct 120. The parts that differ from the first embodiment will be mainly described.

[0045] Fig. 9 shows a state in which the media lid 150 is open. Fig. 10 is a cross-sectional view similar to Fig. 4, taken along the XZ cross section including the optical axis C0.

[0046] 8 and 10, the air intake 1342 is disposed at a position recessed (concave) toward the -X side with respect to the protruding portion 111 of the grip portion 110. This makes it possible to prevent the air intake 1342 from being blocked by the hand of the photographer holding the grip portion 110, and ensures a sufficient amount of air to be taken into the cooling duct 120. In addition, since the hole shape of the air intake 1342 is difficult to see even when viewed from the front side where it is easily visible, it becomes easier to dispose the air intake 1342 on the front side without spoiling the appearance.

[0047] Figures 11(a) to (c) are rear perspective cross-sectional views of the -X side end in an XZ cross-section including the optical axis C0. Figures 12(a), (b), and 13 are cross-sectional views in an XZ cross-section including the optical axis C0, and correspond to Figures 11(a) to (c). Figures 11(a) to (c), 12(a), (b), and 13, like Figures 7(a) to (c), show a series of operations from when the media cover 150 is in the open state, through the closed state, to when it is in the locked state, with the recording medium 141 inserted in the media slot 143.

[0048] Figures 11(a), (b), and (c) respectively show the open, closed, and locked states of the media lid 150. Figures 12(a) and (b) respectively show the open and closed states of the media lid 150. Figure 13 shows the media lid 150 in the locked state.

[0049] 11(a) and 12(a), when the media cover 150 is open, the media insertion opening 143a of the media slot 143 is open, allowing the insertion / removal of the recording medium 141. Also, in this state, the duct hole 122 formed on the -X side surface of the cooling duct 120 is exposed. The duct hole 122 communicates with the air flow path of the cooling duct 120.

[0050] As shown in FIG. 13, the media cover 150 includes a cover member 154, a heat conductive member 155, and an elastic member 157. The elastic member 157 is, for example, a coil spring, but may be a member such as rubber. The heat conductive member 155 integrally includes abutting portions 152 and 153, a fin shape 156 (heat dissipation fin), and a locking portion 158. The cover member 154 integrally includes a claw portion 154a. The elastic member 157 is disposed so as to be interposed between the locking portion 158 and the claw portion 154a. The heat conductive member 155 is supported so as to be movable parallel to the cover member 154 in the direction of expansion and contraction of the elastic member 157.

[0051] The media cover 150 protects the recording medium 141 by rotating about the rotation shaft 151 from the open state shown in Figures 11(a) and 12(a) to the closed state (Figures 11(b) and 12(b)). The media cover 150 is slid from the closed state together with the rotation shaft 151 in the +Z direction to a locked state in which it is fixed to the device body 100 by a fixing mechanism (not shown) (Figures 11(c) and 13).

[0052] That is, in the process of sliding cover member 154 in the +Z direction from the closed state to the locked state, claw portion 154a presses engaging portion 158 toward the +Z side via elastic member 157, causing heat conduction member 155 as a whole to move toward the +Z side. When abutment portion 152 eventually abuts against recording medium 141, the movement of heat conduction member 155 almost stops. As cover member 154 slides further toward the +Z side, elastic member 157 is compressed, and eventually media lid 150 enters the locked state (FIGS. 11(c) and 13).

[0053] In the locked state, the engaging portion 158 is biased toward the +Z side by the biasing force of the compressed elastic member 157. As a result, the entire heat conducting member 155 is biased toward the +Z side, so that the abutting portion 152 is in pressure contact with the -Z side surface of the recording medium 141. This ensures that heat is transferred from the recording medium 141 to the heat conducting member 155.

[0054] In the locked state, the abutment portion 153 blocks the duct hole 122, and the fin shape 156 is inserted into the air flow path of the cooling duct 120 through the duct hole 122. This allows the heat of the air in the cooling duct 120 to be released through the media cover 150. A cushion 124 (FIGS. 12(a) and 13) is attached around the duct hole 122. In the locked state, the cushion 124 is sandwiched between the periphery of the duct hole 122 and the abutment portion 153, thereby preventing air from leaking from the duct hole 122.

[0055] According to this embodiment, it is possible to obtain the same effect as the first embodiment in terms of efficiently cooling the recording medium 141. Furthermore, since a heat transfer path from the recording medium 141 to the cooling duct 120 is formed via the media cover 150, it is possible to further increase the cooling efficiency of the recording medium 141.

[0056] (Third embodiment) An imaging device according to a third embodiment of the present invention will be described. Fig. 14 is a cross-sectional view similar to Fig. 4, taken along an XZ plane including the optical axis C0. This embodiment differs from the first embodiment mainly in that the arrangement of the cooling fan 131 is different.

[0057] 14, the cooling fan 131 is disposed so that a part of it fits inside the protruding portion 111 of the grip portion 110. Here, a device such as the imaging device 1 in which the grip portion 110 is integrally provided at one end of the device body 100 and the main circuit board 170 is disposed perpendicular to the optical axis C0 is often short in the Z direction and long in the X direction. Here, when the cooling fan 131 is mounted on the device body 100, if the cooling fan 131 and the main circuit board 170 are disposed so as to overlap in the Z direction, the dimension in the Z direction becomes large.

[0058] Therefore, in this embodiment, by disposing a part of the cooling fan 131 inside the protruding portion 111, it is possible to mount the cooling fan 131 inside the apparatus body 100 while suppressing an increase in the size in the Z direction.

[0059] Outside air taken in from intake port 1341 by cooling fan 131 passes through intake duct 132, and then passes through cooling fan 131 and cooling duct 120 in that order. The air exchanges heat with cooling duct 120, which has become hot due to heat transfer from a heat generating part, and the temperature of the air increases. Then, the air is discharged to the outside from exhaust port 135.

[0060] According to this embodiment, in terms of efficient cooling of the recording medium 141, the same effect as in the first embodiment can be achieved.

[0061] Furthermore, since a portion of the cooling fan 131 fits inside the protruding portion 111, the increase in size in the Z direction can be suppressed.

[0062] In this embodiment, the configuration other than the arrangement of the cooling fan 131 may be the same as that of either the first or second embodiment.

[0063] In each of the above embodiments, the positional relationship between main circuit board 170 and cooling duct 120 in the Z direction is such that cooling duct 120 is disposed on the -Z side of main circuit board 170. However, these positional relationships may be reversed. Also, the intake ports 1341 and 1342 are disposed at the base of protrusion 111 on the +X side of grip portion 110. However, intake ports 1341 and 1342 may be provided at the tip or -X side of protrusion 111, and may further be disposed biased toward either the top surface side or the bottom surface side in the Y direction.

[0064] In each embodiment, the term "approximately" does not mean to exclude complete. For example, "approximately perpendicular" and "approximately L-shaped" are intended to include complete perpendicular and approximately L-shaped, respectively.

[0065] Although the present invention has been described in detail based on the preferred embodiments, the present invention is not limited to these specific embodiments, and various forms within the scope of the gist of the present invention are also included in the present invention. Parts of the above-described embodiments may be combined as appropriate.

[0066] The disclosure of this embodiment includes the following configuration. (Configuration 1) A grip portion provided at an end of a main body of the device, the grip portion including a protruding portion protruding toward a subject in an optical axis direction; a media substrate on which a media storage section for storing a recording medium is mounted and which is disposed on an opposite side of the protrusion from an object side in the optical axis direction; A main circuit board disposed substantially perpendicular to the optical axis; a cooling duct including a first extension portion extending in a direction intersecting the optical axis direction within the grip portion, the cooling duct being thermally connected to the media board and the main circuit board; and an air-cooling fan that introduces air into the cooling duct.
