Further, in this specification, the side of the imaging device on which the subject is present is referred to as the "front side", and the side of the imaging device on which the subject is present is referred to as the "rear side".

As shown in FIGS. 1 to 3, in the case of the present embodiment, the housing of the imaging device 10 includes a front casing 12 positioned on the front side, a top casing 13 positioned on the upper side, and a rear casing 14 positioned on the rear side. and a side casing 16 located on the left side.

As shown in FIG. 1, the front casing 12 is provided with a lens mounting portion. It should be noted that the lens mounting portion is hidden by the lens cap 18 in the drawing. Further, the front casing 12 is provided with a handgrip portion 12a that is gripped by the user's right hand. Furthermore, the front casing 12 is provided with a plurality of man-machine interfaces.

A plurality of man-machine interfaces such as a shutter button 20 are provided on the top casing 13 .

As shown in FIGS. 2 and 3, the rear casing 14 is provided with a viewfinder 22 . Also, the rear casing 14 is provided with a plurality of man-machine interfaces such as a dial 24 . Some man-machine interfaces such as the dial 24 are located on the right side of the outer surface of the rear casing 14 (that is, the rear surface of the imaging device 10) so that they can be operated with the thumb of the user's right hand holding the handgrip portion 12a. are placed in

Furthermore, as shown in FIGS. 2 and 3, in the case of the present embodiment, a monitor 26 is mounted on the left portion of the outer surface of the rear casing 14. As shown in FIG. Specifically, the monitor 26 is attached to a rectangular plate-shaped tilt base 28 via a hinge 30 . A raised portion 14b having a flat top surface 14a is formed on the outer surface of the rear casing 14. As shown in FIG. A tilt base 28 is provided so as to be tiltable with respect to the top surface 14a of the raised portion 14b. Specifically, the tilt base 28 rotates around a rotation center line extending in the left-right direction (Y-axis direction) of the imaging device 10 . Note that FIG. 2 shows the tilt base 28 in a state in which the tilt base 28 is closest to the top surface 14a of the raised portion 14b, ie, the tilt base 28 is positioned at the retracted position.

The monitor 26 is, for example, a liquid crystal monitor having a display surface 26a. For example, the monitor 26 displays an image (through-the-lens image) represented by image data captured by an imaging device and image-processed by an image processing unit. The monitor 26 is provided on the tilt base 28 so as to be movable between a position overlapping the tilt base 28 and a position separated from the tilt base 28 . Specifically, the monitor 26 is supported by the hinge 30 so as to be rotatable around a rotation center line C1 extending in the left-right direction (Y-axis direction) of the imaging device 10 . The hinge 30 is supported by the tilt base 28 so as to be rotatable around a rotation center line C2 that is orthogonal to the rotation center line C1 and parallel to the tilt base 28. As shown in FIG. With such a hinge 30, the monitor 26 is stored with its display surface 26a overlapping the tilt base 28 as shown in FIG. Further, as shown in FIG. 3, the monitor 26 can take a posture that is separated from the tilt base 28 and that the display surface 26a faces the rear of the imaging device 10. As shown in FIG.

An arc-shaped concave portion 28a is formed at the right end of the tilt base 28 so that the monitor 26 can be easily rotated around the rotation center line C2 from the retracted state shown in FIG. A portion of the display surface 22a of the monitor 26 overlapping the tilt base 28 is exposed by the recess 28a. As a result, the user's finger can easily be placed on the exposed portion, that is, the free end of the monitor 26 (that is, the distal end farther from the hinge 30 in the left-right direction (Y-axis direction)), and as a result, the user can easily rotate the monitor 26. (compared to the case where there is no recess 28a).

In addition, the concave portion 28 a of the tilt base 28 prevents the thumb of the right hand of the user who rotates the dial 24 from contacting the tilt base 28 . Thereby, the user can smoothly rotate the dial 24 without feeling any stress. In other words, the existence of this concave portion 28a enables the dial 24 to be arranged near the tilt base 28, and as a result, the size of the imaging device 10 in the left-right direction (Y-axis direction) can be reduced. .

Furthermore, in the case of this embodiment, the rear casing 14 is provided with an intake port and an exhaust port.

FIG. 4 is a rear perspective view of the imaging device disassembled for maintenance. Also, FIG. 5 is a rear perspective view of the image pickup apparatus with the air inlet cover removed. FIG. 6 is a side perspective view of the imaging device with the side casing removed. 4 shows the front casing 12 with the top casing 13 attached.

As shown in FIGS. 4 and 5, the rear casing 14 is provided with an intake port 14c for drawing outside air into the imaging device 10. As shown in FIGS. Specifically, an intake port 14c is formed from the top surface 14a of the raised portion 14b of the rear casing 14 to the side surface 14d of the raised portion 14b on the dial 24 side.

In order to prevent large foreign objects from entering the air intake 14c, an air intake cover 32 is attached to the air intake 14c. In the case of this embodiment, the intake port cover 32 is fixed to the rear casing 14 with one screw 34 in order to facilitate cleaning of the inside of the imaging device 10 near the intake port 14c. The screw 34 is attached to the rear casing 14 in the front-rear direction (X-axis direction) of the imaging device 10 . 2, the screw 34 is provided at a position covered by the tilt base 28 in the retracted state as shown in FIG. 2, and when the tilt base 28 is tilted as shown in FIG. A tool for rotating the screw 34 is provided at a position where the screw 34 can be accessed in the front-rear direction (X-axis direction).

Incidentally, as shown in FIG. 2, the recess 28a of the tilt base 28 is positioned on the intake port cover 32. As shown in FIG. To explain, when the tilt base 28 is in the retracted state as shown in FIG. 2, the right end of the tilt base 28 covers a portion of the intake port cover 32 (that is, the intake port 14c). As a result, compared to the case where the tilt base 28 is tilted away from the top surface 14a of the raised portion 14b as shown in FIG. 3, the intake efficiency of the intake port 14c is lowered. The concave portion 28 a of the tilt base 28 in the retracted state is positioned on the intake port cover 32 in order to suppress a decrease in intake efficiency when the tilt base 28 is in the retracted state.

As shown in FIG. 6, the rear casing 14 is provided with an exhaust port 14e for exhausting external air drawn into the imaging device 10 through the intake port 12c. Specifically, an exhaust port 14 e is formed in the left portion of the rear casing 14 .

The exhaust port 14e is prevented from entering large foreign matter by an exhaust port cover portion 16a formed in the side casing 16. As shown in FIG. In this embodiment, the side casing 16 is attached to the front casing 12 and the rear casing 14 with three screws 36 in order to facilitate cleaning of the inside of the imaging device 10 near the exhaust port 14e. The side casing 16 is provided with a door-shaped cover 40 for protecting the earphone jack 38, and a door-shaped cover 46 for protecting the USB terminal connector 42 and the HDMI (registered trademark) connector 44. there is

FIG. 7 is a front perspective view of the imaging device disassembled into a front unit and a rear unit. 7 shows the front casing 12 with the top casing 13 attached.

As shown in FIGS. 4 and 7, the front unit 50 is constructed by incorporating a plurality of components into the front casing 12, and the rear unit 52 is constructed by incorporating a plurality of components into the rear casing 14. As shown in FIGS. 4 and 7, flexible cables and the like for electrically connecting the front unit 50 and the rear unit 52 are omitted.

As shown in FIG. 4, a board 54 is provided inside the front unit 50 . In the case of the present embodiment, the substrate 54 is provided over the entire front casing 12 in the left-right direction (Y-axis direction) of the imaging device 10 . A memory 56 such as a DRAM, an IC chip 58 for image processing, and the like are mounted on the rear surface of the substrate 54 (surface on the rear side of the imaging device 10). In this embodiment, memory 56 and IC chip 58 are provided on the left side of substrate 54 .

A card connector 60 into which a recording medium M is detachably inserted is provided on the rear surface of the substrate 54 . The recording medium M is a card-type recording medium (so-called memory card), such as a CFexpress card. Specifically, the card connector 60 is roughly composed of a portion of the substrate 54 provided with terminals (not shown) for electrically connecting to the terminals of the recording medium M, and a portion of the substrate 54 for receiving the recording medium M. It is composed of a connector frame (recording medium accommodating portion) 62 that covers the board 54 with a space therebetween and maintains contact between the terminals on the substrate 54 and the terminals of the recording medium M. As shown in FIG. The connector frame 62 is made by processing a thin plate of metal such as stainless steel. In this embodiment, the card connector 60 is provided on the right side of the board 54 away from the memory 56 and the IC chip 58 . Access to the card connector 60 of the recording medium M is made possible by opening a connector cover 64 provided on the right side of the imaging device 10 .

As shown in FIG. 7, a radiator plate 66 is provided inside the rear unit 52 . The heat sink 66 is a plate-like member made of a metal material such as copper having high thermal conductivity. The heat sink 66 cools the recording medium M inserted into the card connector 60 by absorbing heat from the connector frame 62 of the card connector 60 . Further, in the case of the present embodiment, the heat sink 66 absorbs heat from the memory 56 and the IC chip 58 (heat source) to cool them. In the case of the present embodiment, the radiator plate 66 is not provided over the entire rear casing 14 in the left-right direction (Y-axis direction) of the imaging device 10, but is provided from the central portion to the left portion of the rear casing 14. there is

The imaging device 10 has a heat transfer element that thermally connects the memory 56 , IC chip 58 and card connector 60 provided in the front unit 50 and the radiator plate 66 provided in the rear unit 52 .

8A and 8B are perspective views of the imaging device showing heat transfer elements that thermally connect the front unit and the rear unit. 8A is a front perspective view and FIG. 8B is a rear perspective view. 8A and 8B show the front casing 12 with the top casing 13 attached.

As shown in FIGS. 8A and 8B, the radiator plate 66 faces the memory 56 and the IC chip 58 in the thickness direction of the substrate 54, that is, in the front-rear direction (X-axis direction) of the imaging device 10. As shown in FIGS. Therefore, in order to thermally connect the memory 56 and the IC chip 58 to the radiator plate 66, silicon adhesive sheets 68 and 70 having high thermal conductivity and flexibility are arranged therebetween. The silicon adhesive sheets 68 and 70 are in surface contact with the memory 56 and the IC chip 58, and are also in surface contact with the front surface 66a of the heat sink 66 (surface on the front side of the imaging device 10). A silicon adhesive sheet 72 is also placed between the portion of the substrate 54 near the memory 56 and the IC chip 58 and the radiator plate 66 . The silicon adhesive sheet 72 is in surface contact with the substrate 54 and in surface contact with the radiator plate 66 . Heat from the memory 56 , the IC chip 58 and the substrate 54 is transferred to the radiator plate 66 through these silicon adhesive sheets 68 , 70 and 72 .

The silicone adhesive sheets 68, 70, and 72 have self-adhesiveness that allows repeated attachment. Therefore, when the imaging device 10 is disassembled into the front unit 50 and the rear unit 52 for maintenance, the silicon adhesive sheets 68, 70, and 72 are attached to the memory 56, the IC chip 58, and the substrate as shown in FIG. 54 (or remains on the heat sink 66). When the maintenance is completed and the front unit 50 and the rear unit 52 are reassembled, the silicon adhesive sheets 68, 70 and 72 heat the memory 56, the IC chip 58, the substrate 54 and the radiator plate 66 again. connected to each other. Therefore, the imaging device 10 ensures high heat dissipation for the memory 56, the IC chip 58, and the substrate 54, and has high maintainability (easiness of disassembly and assembly). In other words, the thermal connections between the memory 56, the IC chip 58, the substrate 54 and the radiator plate 66 are released only by disassembling the front unit 50 and the rear unit 52. FIG. Further, thermal connection between the memory 56, the IC chip 58, the substrate 54 and the heat sink 66 is established only by combining the front unit 50 and the rear unit 52 together. As a result, the user does not have to do anything with regard to the thermal connections between memory 56 , IC chip 58 , substrate 54 and heat sink 66 .

On the other hand, as shown in FIGS. 8A and 8B, the heat sink 66 faces the connector frame 62 of the card connector 60 in the thickness direction of the board 54, that is, in the front-rear direction (X-axis direction) of the imaging device 10. not Specifically, the heat sink 66 is provided at a position leftwardly away from the connector frame 62 of the card connector 60 . As a means for thermally connecting the connector frame 62 of the card connector 60 and the radiator plate 66 which are separated in this way, the imaging device 10 has a thermally conductive sheet 74 .

As shown in FIG. 8A, the thermally conductive sheet 74 is a flexible sheet with high thermal conductivity, and in the case of the present embodiment, extends in the left-right direction (Y-axis direction) of the imaging device 10. It is a strip-shaped thin sheet. Moreover, in the case of the present embodiment, the thermally conductive sheet 74 is a graphite sheet. A graphite sheet is made by processing graphite having high thermal conductivity into a thin sheet.

As shown in FIGS. 7 and 8A, one end (first portion) 74a of the heat conductive sheet 74 is attached and fixed to the right end of the radiator plate 66 included in the rear unit 52 via the adhesive sheet 76. As shown in FIG. ing. As a result, the heat conductive sheet 74 is included in the rear unit 52 .

In order to easily disassemble the front unit 50 and the rear unit 52 , the heat conductive sheet 74 is not fixed to the connector frame 62 of the card connector 60 included in the front unit 50 . The heat-conducting sheet 74 simply surface-contacts the top plate portion 62a of the connector frame 62 via the other end (second portion) 74b. The imaging device 10 has a cushion member 78 that biases the other end 74b of the heat conductive sheet 74 toward the top plate portion 62a of the connector frame 62 in order to maintain the surface contact.

The cushion member 78 is made of an elastic material such as urethane foam and has lower rigidity than the connector frame 62 . In the case of this embodiment, the cushion member 78 is attached to the second portion 74b of the heat conductive sheet 74 via the adhesive sheet 80 . The cushion member 78 is provided on the rear casing 14 and supported by a base plate (cushion member support member) 82 to which a man-machine interface such as the dial 24 provided on the rear casing 14 is attached.

The second portion 74b of the heat conductive sheet 74 is sandwiched between the top plate portion 62a of the connector frame 62 and the cushion member 78 when the front unit 50 and the rear unit 52 are combined. In that state, the cushion member 78 is compressed and deformed between the connector frame 62 and the base plate 82 . As a result, the cushion member 78 urges the second portion 74b of the heat conductive sheet 74 toward the connector frame 62 with an urging force that does not deform the connector frame 62 . Thereby, contact between the heat conductive sheet 74 and the connector frame 62 is maintained. As a result, the connector frame 62 is thermally connected to the radiator plate 66 via the heat conductive sheet 74 .

When the imaging device 10 is disassembled into the front unit 50 and the rear unit 52 for maintenance, the second portion 74b of the heat conductive sheet 74 is separated from the top plate portion 62a of the connector frame 62. As shown in FIG. When the maintenance is completed and the front unit 50 and the rear unit 52 are reassembled, the second portion 74b of the heat conductive sheet 74 comes into surface contact with the top plate portion 62a of the connector frame 62 again. Therefore, the image capturing apparatus 10 can ensure high heat dissipation with respect to the connector frame 62, specifically, the recording medium M inserted in the connector frame 62, and high maintainability (easiness of disassembly and assembly). Prepare. That is, the thermal connection between the connector frame 62 and the radiator plate 66 is released only by disassembling the front unit 50 and the rear unit 52 . Further, thermal connection between the connector frame 62 and the heat sink 66 is established simply by combining the front unit 50 and the rear unit 52 . As a result, at the time of maintenance such as repair, there is no need to perform any work regarding the thermal connection between the connector frame 62 and the heat sink 66 . Moreover, the heat conductive sheet 74 is not broken when the rear unit 52 is removed, and can be reused.

In this embodiment, the cushion member 78 is attached to the second portion 74b of the heat conductive sheet 74 via the adhesive sheet 80. As shown in FIG. Alternatively, the cushion member 78 may be attached to the base plate 82 without being attached to the heat conductive sheet 74 . Also, instead of the base plate 82 , another member for supporting the cushion member 78 may be provided in the rear unit 52 .

In this embodiment, the radiator plate 66 is cooled by outside air.

9A and 9B show the rear unit with the heat sink removed. 9A is a front perspective view and FIG. 9B is a rear perspective view. Note that the monitor 26, tilt base 28, and hinge 30 are omitted in FIGS. 9A and 9B.

As described above and as shown in FIG. 9A, the rear casing 14 of the rear unit 52 is provided with the intake port 14c. The outside air that has passed through the intake port 14 c flows between the radiator plate 66 and the rear casing 14 . A fan 84 is attached to the rear surface 66 b of the radiator plate 66 facing the rear casing 14 in order to generate such an inflow of outside air. That is, fan 84 is included in rear unit 52 .

In this embodiment, the fan 84 is a sirocco fan, as shown in FIG. 9B. Specifically, the fan 84 sucks the outside air in the extending direction (X-axis direction) of the rotation center line R of the fan through the suction port 84a. Further, the fan 84 blows out the sucked outside air in a direction perpendicular to the extending direction of the rotation center line R (Y-axis direction) through the blowout port 84b. Note that the fan 84 is provided in the rear unit 52 so that the extending direction of the rotation center line R thereof is parallel to the front-rear direction of the imaging device 10 .

A heat sink 86 is arranged in front of the outlet 84 b of the fan 84 . The heat sink 86 is attached to and thermally connected to the rear surface 66 b of the heat sink 66 . The heat sink 86 also includes a plurality of fins 86a extending in the horizontal direction (Y-axis direction) of the imaging device 10 and arranged in the height direction (Z-axis direction) at intervals.

When the fan 84 rotates, outside air is drawn into the imaging device 10 through the intake port 14c (the intake port cover 32) of the rear casing 14. As shown in FIG. The taken outside air enters the fan 84 through the suction port 84a and is blown out through the blowout port 84b. The blown outside air passes between the plurality of fins 86 a of the heat sink 86 . At that time, the outside air takes the heat transferred from the radiator plate 66 to the heat sink 86 through the plurality of fins 86a. Then, the outside air in a high-temperature state by taking heat is discharged to the outside of the imaging device 10 through the exhaust port 14 e (exhaust port cover portion 16 a ) of the rear casing 14 . Such a flow of outside air cools the heat sink, and as a result cools the connector frame 62, the memory 56, the IC chip 58, and the substrate 54 of the card connector 60, which are thermally connected to the heat sink 66. .

According to the present embodiment as described above, it is possible to achieve high maintainability while ensuring high heat dissipation performance for the recording medium in an imaging apparatus that stores captured moving images and the like in a removable recording medium. That is, even if the connector of the recording medium and the heat sink are included in separate units when the imaging apparatus is disassembled into a plurality of units for maintenance, the heat between the connector frame of the connector and the heat sink is Connections can be easily and reversibly broken.
