Description

  The present invention relates to an imaging apparatus such as a digital camera, and particularly relates to an imaging apparatus with improved heat dissipation characteristics.

  In recent years, heat generation of the image sensor has become a problem due to the increase in size and the number of pixels of the image sensor. Still camera such as a digital camera is required to have a moving image shooting function, which accelerates the problem of heat generation of the image sensor. In order to capture high-quality moving images, the drive frequency of the image sensor tends to increase.

  In addition, in control LSIs and signal processing LSIs for processing and recording high pixel image data and moving image data, higher integration has progressed and drive frequency has increased. Therefore, the heat generated from these LSIs cannot be ignored.

  Even in such a situation, the demand for downsizing and thinning of the imaging device continues. Therefore, these heat generation problems must be solved without enlarging the imaging device itself.

  As for heat dissipation of the image sensor, it is common to attach a heat radiating plate to the back surface of the image sensor. Patent Document 1 describes a heat radiating device for a charge coupled device in which a heat radiating plate is attached to the back surface of an image sensor. Patent Document 2 describes a heat radiating device for a camera in which a heat radiating plate is attached to the back surface of an image sensor. Further, Patent Document 3 describes a heat dissipation structure for an image sensor in which a heat dissipation plate and a heat dissipation portion are connected by a heat dissipation path extending to the heat dissipation plate.

  However, it is difficult to efficiently dissipate the heat generated by the image sensor only with the heat sink attached to the back surface of the image sensor. In addition, there are heat sources such as a control LSI and a signal processing LSI in addition to the image sensor. On the other hand, the demand for downsizing and thinning of the imaging device is severe, and since it is a portable device, it is not preferable to easily dissipate heat to the housing.

  An object of the present invention is to provide an imaging device that solves the above-described problems and further improves the heat dissipation efficiency.

  In order to solve the above problems, an imaging apparatus according to the present invention includes a battery storage case formed of a heat conductive material, a first heat radiating plate supported at one end on the front side of the battery storage case, and the battery storage. A second heat radiating plate supported at one end on the back side of the case, wherein the first heat radiating plate and the second heat radiating plate face each other.

  As described above, according to the present invention, the battery housing in which the first heat radiating plate disposed from the front surface of the imaging device and the second heat radiating plate disposed from the back surface of the imaging device are formed of a heat conductive material. Since the case is mechanically and thermally connected, it is possible to increase the heat radiation area, thereby providing an effect of providing an imaging device with improved heat radiation efficiency.

(Embodiment)
Hereinafter, a digital camera according to an embodiment of the present invention will be described in detail with reference to the drawings.
(1. Appearance)
FIG. 1 is an external view of a digital camera according to an embodiment of the present invention. FIG. 1A is a front view, and FIG. 1B is a rear view.

  The digital camera according to the embodiment of the present invention is an interchangeable lens type digital camera, and various types of interchangeable lenses can be attached to the mount 101 to enjoy photographing. A plurality of electrical contacts 102 are provided in a circular arc shape on a part of the inner periphery of the mount 101. When the interchangeable lens is attached to the mount 101, communication between the digital camera and the interchangeable lens becomes possible via the electrical contact 102. The digital camera acquires information specific to the interchangeable lens from the interchangeable lens and controls the operation of the interchangeable lens according to the shooting conditions. When the interchangeable lens is rotated while pressing the lens removal button 103, the interchangeable lens can be detached from the mount 101.

  Since the digital camera according to the embodiment of the present invention is not a so-called single-lens reflex digital camera, it does not include a movable mirror that switches whether the incident light from the interchangeable lens is guided to the image sensor or the optical viewfinder. Therefore, the image sensor 104 can be directly viewed inside the mount 101. However, an ultrasonic filter for removing attached dust and an optical low-pass filter for removing high-frequency components of incident light are disposed on the front surface of the image sensor 104.

  On the upper surface of the digital camera, operation members such as a shutter button 105 for instructing shooting and mode dials 106 and 107 for making various settings related to shooting are arranged. A pop-up strobe 108 is built in the upper surface of the digital camera. FIG. 1 shows a state in which the strobe 108 is stored. On the top of the strobe 108, a hot shoe 109 to which an external strobe device or the like having a larger light emission amount can be attached is provided. Metal fittings 110 for attaching straps are provided on the left and right sides of the digital camera.

  A movable monitor 111 is disposed on the back of the digital camera. The movable monitor 111 employs a flat display such as a liquid crystal monitor. The movable monitor 111 displays an image based on incident light imaged on the image sensor 104. In the state shown in FIG. 1B, the display surface of the movable monitor 111 is closed to the digital camera side. The movable monitor 111 can be opened to the near side of FIG. The movable monitor 111 can rotate around the Y axis. Therefore, the position of the movable monitor 111 can be adjusted to the position where it is most visible according to the shooting conditions.

  The digital camera according to the embodiment of the present invention also includes an electronic viewfinder 112 in addition to the movable monitor 111. The electronic viewfinder 112 is composed of a small liquid crystal monitor and an eyepiece optical system, and displays an image based on incident light imaged on the image sensor 104, similarly to the movable monitor 111. Since the electronic viewfinder 112 is a type of viewfinder, a clear image can be visually recognized by the electronic viewfinder 112 even when the external monitor is too bright and it is difficult to visually recognize the movable monitor 111. An eye sensor 113 is arranged in the vicinity of the electronic viewfinder 112. The eye sensor 113 detects an eyepiece with respect to the electronic viewfinder 112. When the eye sensor 113 detects an eyepiece on the electronic viewfinder 112, the display of the image based on the incident light imaged on the image sensor 104 is switched from the movable monitor 111 to the electronic viewfinder 112.

On the back of the digital camera, various operation buttons 114 including a cross key and operation members such as an operation dial 115 are arranged. By using these operation members, detailed settings such as shooting and reproduction can be performed. A slot into which a memory card can be inserted is provided on the right side when viewed from the back of the digital camera. This slot is concealed by a cover 116.
(2. Overall configuration)
FIG. 2 is an exploded perspective view of the digital camera according to the embodiment of the present invention. The digital camera according to the embodiment of the present invention includes a front case 201, a first heat sink 202, a mount unit 203, a battery unit 204, a second heat sink 205, a main board 206, and a rear case 207 from the front side. Configured in order.

  The mount unit 203 is based on a frame made of a material having high thermal conductivity and rigidity such as aluminum. The mount unit 203 includes, from the front side, a mount 101 having an electrical contact 102, a shutter, and an image sensor 104 having an ultrasonic filter and an optical low-pass filter. The image sensor 104 serves as a heat source. In addition, the digital camera according to the embodiment of the present invention maintains the shutter open during the monitor display for determining the composition and during the moving image shooting. Therefore, in order to maintain the shutter open, the shutter curtain is electromagnetically operated by a solenoid. When a shutter with a fixed structure is employed, the solenoid may become a heat source. The solenoid exists in the vicinity of the stepping motor 203a for charging the shutter.

  The battery unit 204 includes a battery storage case and a bottom plate 204d. The battery storage case is configured to wrap the battery 204c by a battery storage case 1 / 204a disposed on the front side and a battery storage case 2 / 204b disposed on the back side. The battery storage case 1 / 204a and the battery storage case 2 / 204b are made of metal having high thermal conductivity. A part of the battery storage case 1 / 204a is bent and mechanically and thermally connected to the battery storage case 2 / 204b.

  Note that the battery storage case does not have to be constituted only by the battery storage case 1 / 204a and the battery storage case 2 / 204b. The battery storage case may be configured to include a member using resin or the like in part. Further, the battery storage case may be entirely configured by a member using resin or the like, and may be configured so as to surround the periphery thereof by the battery storage case 1 / 204a and the battery storage case 2 / 204b. Further, the battery storage case 1 / 204a and the battery storage case 2 / 204b may be integrated. In short, the battery housing case 1 / 204a and the battery housing case 2 / 204b or the battery housing case in which these are integrated, the first heat radiating plate 202 disposed from the front of the digital camera and the back of the digital camera. What is necessary is just to be able to connect the 2nd heat sink 205 thermally.

  The bottom plate 204d is made of a metal having high thermal conductivity. The bottom plate 204 d is mechanically and thermally connected to an extending portion 202 b that is partially bent toward the bottom surface of the first heat radiating plate 202. The bottom plate 204d is mechanically and thermally connected to an extending portion 208a that is partially bent to the bottom surface side of the third heat radiating plate 208. Therefore, the first heat radiating plate 202 disposed on the front surface of the digital camera and the third heat radiating plate 208 disposed on the inner side of the rear housing 207 can be thermally connected by the bottom surface plate 204d. A screw hole 204e for receiving a screw such as a tripod is attached to the bottom plate 204d. In the digital camera according to the present embodiment, the bottom plate 204d is used for heat dissipation. Therefore, it is desirable to form the screw hole 204e with a member having low thermal conductivity so that heat is not transmitted to the screw hole 204e exposed to the outside of the housing.

  A part of the bottom plate 204d may be mechanically and thermally connected to the battery storage case 1 / 204a and / or the battery storage case 2 / 204b. Further, a part of the bottom plate 204d may be mechanically and thermally connected to the second heat radiating plate 205. In the digital camera according to the present embodiment, the bottom plate 204d is included in the battery unit 204, but one or more of the first heat sink 202, the second heat sink 205, and the third heat sink 208 are included. The bottom plate may be formed by bending the part to the bottom. A configuration in which the bottom plate 204d is not used for heat dissipation is also conceivable. When the bottom plate 204d is not used for heat dissipation, it is not necessary to consider the thermal conductivity of the member that forms the screw hole 204e. Therefore, the screw hole 204e can be formed of a member having higher rigidity.

  The main board 206 is a printed board on which an electric circuit including a CPU 206a in which a control LSI and a signal processing LSI are integrated is mounted. If the state in which the load on the CPU 206a increases due to moving image shooting or the like continues, the CPU 206a becomes a heat source. In addition to the CPU 206a, the main board 206 has a slot 206b into which a memory card can be inserted, and a terminal for connecting an external personal computer, a printer, a television receiver, and the like to the digital camera according to the embodiment of the present invention. A group 206c and the like are mounted.

  The battery unit 204, the first heat radiating plate 202, and the second heat radiating plate 205 are assembled so as to enclose the mount unit 203. The mount unit 203 includes an image sensor 104 that is a heat source and a solenoid that may be a heat source. The first heat sink 202 is mechanically and thermally connected to the battery storage case 1 / 204a. In order to further strengthen the thermal connection between the first heat radiating plate 202 and the battery storage case 1 / 204a, the first heat radiating plate 202 is provided with an extending portion 202a that is in close contact with the battery storage case 1 / 204a. Yes. The second heat radiating plate 205 is mechanically and thermally connected to the battery storage cases 2 and 204b. In order to further strengthen the thermal connection between the second heat radiating plate 205 and the battery storage case 2 / 204b, the second heat radiating plate 205 is provided with an extending portion 205a that is in close contact with the battery storage case 2 / 204b. Yes.

  The front housing 201, the first heat radiating plate 202, the mount unit 203, and the battery storage case 1 / 204a are fastened together with screws. Moreover, the 2nd heat sink 205 and battery storage case 2 * 204b are fastened together with a screw | thread. However, the connection between the extending portion 202a of the first heat radiating plate 202 and the battery storage case 1 / 204a and the connection between the second heat radiating plate 205 and the battery storage case 2 / 204b may be performed by a heat conductive adhesive, You may carry out with a conductive adhesive tape. Moreover, even if it is a case where it fastens with a screw | thread, you may apply | coat a heat conductive grease to a contact part.

  The first heat radiating plate 202 alone can only radiate the heat generated by the image sensor 104 and the solenoid through the frame that is the basis of the mount unit 203. However, in the digital camera according to the present embodiment, since the first heat radiating plate 202 is thermally connected to the second heat radiating plate 205 via the battery storage case, the heat absorbed by the second heat radiating plate 205 is absorbed. Heat can be radiated from the battery storage case and the first heat radiating plate 202. Further, the second heat radiating plate is formed not only on the back side of the image sensor 104 but also on the back side of the solenoid. Accordingly, the second heat radiating plate 205 can absorb not only the heat generated by the image sensor 104 but also the heat generated by the solenoid. In other words, the first heat radiating plate 202, the second heat radiating plate 205, and the battery storage case are linked to each other, while the heat radiating by the first heat radiating plate 202, the heat absorption by the second heat radiating plate, and the battery storage case. The first heat radiating plate 202 and the second heat radiating plate 205 are also responsible for heat dissipation.

  As described above, the first heat radiating plate 202 arranged from the front surface of the digital camera according to the embodiment of the present invention and the second heat radiating plate 205 arranged from the back surface are thermally connected through the battery storage case. By doing so, the heat dissipation area can be further increased. The battery storage case is preferably made of metal in order to hold the heavy battery 204c. Therefore, the battery storage case made of metal can be used for thermal connection between the first heat radiating plate 202 and the second heat radiating plate 205, and the battery storage case itself can be used for heat dissipation.

  Here, if the bottom plate 204d is added, the heat radiation area can be further increased. A screw hole 204e for receiving a screw such as a tripod is attached to the bottom plate 204d. The bottom plate 204d is preferably made of metal in order to firmly fix the digital camera according to the embodiment of the present invention to a tripod or the like. Therefore, the heat radiation area can be further increased by mechanically and thermally connecting the bottom plate 204d made of metal to the extending portion 202b bent to the bottom surface side of the first heat radiation plate 202. Further, the bottom plate 204d is mechanically and thermally connected to the extending portion 208a bent to the bottom surface side of the third heat radiating plate 208, so that the heat absorbed by the third heat radiating plate 208 and the first heat radiating plate Heat can be radiated from the plate 202. The third heat radiating plate 208 is on the back side of the main board 206 and absorbs heat generated by a heat source mounted on the main board 206 such as the CPU 206a.

  Although not adopted in the digital camera according to the present embodiment, a new heat radiating plate mechanically and thermally connected to the battery storage case may be provided on the top of the mount unit 203. Then, the heat radiation area can be further increased. Moreover, since the heat dissipated in the air in the casing rises, the first heat radiating plate 202, the second heat radiating plate 205, the bottom surface plate 204d, the third heat radiating plate are provided by the new heat radiating plate provided on the top of the mount unit 203. The heat dissipated in the air in the housing without being absorbed by the heat radiating plate 208 can be efficiently absorbed. Further, since many operation members are arranged on the upper surface of the digital camera, there is an effect that heat is not transmitted to the upper surface of the digital camera as much as possible.

  At this time, it is more efficient if the new heat radiating plate also serves as a reinforcement of the hot shoe 109 that may be attached with a heavy external strobe device or the like. The new heat radiating plate may be mechanically and thermally connected to any one or more of the first heat radiating plate 202, the second heat radiating plate 205, and the third heat radiating plate 208. Further, any one or a part of the first heat radiating plate 202, the second heat radiating plate 205, and the third heat radiating plate 208 may be bent to the upper part of the mount unit 203 to form a new heat radiating plate.

  A main substrate 206 is disposed on the back side of the second heat radiating plate 205. A CPU 206a, which is a heat source, is mounted on the main board 206. Between the second heat radiation plate 205 and the CPU 206a, a leaf spring 206d and a heat conduction sheet 206e made of phosphor bronze which is a material having a very high thermal conductivity are interposed. The leaf spring 206d is mechanically and thermally connected to the second heat radiating plate 205. The leaf spring 206d itself is brought into pressure contact with the CPU 206a via the heat conductive sheet 206e by the elastic force of the leaf spring 206d. Thus, the heat generated by the CPU 206a can be efficiently guided to the second heat radiating plate 205.

Further, the battery unit 204, the first heat radiating plate 202, and the second heat radiating plate 205 are assembled so as to enclose the mount unit 203 based on a frame made of a highly rigid material. Therefore, if the second heat radiating plate 205 is configured to be in direct contact with the CPU 206a, the CPU 206a may be destroyed due to an impact caused by dropping of the digital camera or the like. Even if the CPU 206a is not destroyed, there is a possibility that a crack may occur in the soldering portion that connects the CPU 206a to the main board 206. Such a problem can be avoided by interposing a leaf spring 206d between the second heat radiating plate 205 and the CPU 206a as in the digital camera according to the embodiment of the present invention.
(3. Structure of main parts)
FIG. 3 is a perspective view of a state in which the mount unit and the battery unit are assembled. FIG. 3A is a perspective view seen from the front side, and FIG. 3B is a perspective view seen from the back side. The battery 204c, the bottom plate 204d and other parts other than the main part of the battery unit 204 are omitted.

  In a state where the mount unit 203 and the battery unit 204 are assembled, the mount unit 203 including the imaging element 104 that is a heat source and a solenoid that may be a heat source is sandwiched between the first heat sink 202 and the second heat sink 205. Is done. And the 1st heat sink 202 and the 2nd heat sink 205 are thermally connected via the battery storage case comprised by battery storage case 1 * 204a and battery storage case 2 * 204b. When the first heat radiating plate 202, the second heat radiating plate 205, and the battery storage case are viewed from above, they have a substantially “U” shape, and the mount unit 203 is taken into the inside.

  The first heat radiating plate 202 absorbs heat generated by the imaging element 104 and the solenoid via the frame 203b that is the basis of the mount unit 203. The second heat radiating plate 205 absorbs not only the heat generated by the image sensor 104 but also the heat generated by the solenoid. The second heat radiating plate 205 absorbs heat generated by the CPU 206a via the leaf spring 206d and the heat conductive sheet 206e. The first heat radiating plate 202 and the second heat radiating plate 205 themselves absorb heat and also radiate heat, but the heat absorbed by the first heat radiating plate 202 and the second heat radiating plate 205 is absorbed by the battery storage case 1 / 204a. Heat is also radiated from the battery storage case constituted by the battery storage cases 2 and 204b.

  As described above, the first heat radiating plate disposed from the front surface of the imaging device and the second heat radiating plate disposed from the back surface are thermally connected via the battery storage case preferably made of metal. By doing so, the heat dissipation area can be further increased. In addition, the battery storage case often occupies from the front side to the back side of the image pickup device as the image pickup device is recently thinned, and is often located relatively far from the heat source. It is convenient for thermally connecting the first heat radiating plate and the second heat radiating plate and efficiently radiating the heat absorbed by the first heat radiating plate and the second heat radiating plate. Furthermore, by arranging a printed circuit board on which a control LSI or a signal processing LSI as a heat source is mounted on the back side of the second heat radiating plate, the heat generated by these LSIs can be efficiently absorbed by the second heat radiating plate. The heat can be dissipated from the battery storage case. Furthermore, you may provide the new heat sink thermally connected with any one or more of a battery storage case, a 1st heat sink, a 2nd heat sink at the upper part and the lower part of a mount unit. In addition, on the back side of the printed circuit board, there is a third heat radiating plate thermally connected to one or more of a battery housing case, a second heat radiating plate, and a new heat radiating plate provided on the upper and lower parts of the mount unit. It may be provided.

  In short, the basic technical idea of the present invention is to thermally connect a plurality of heat radiating plates arranged in the width direction of the image pickup apparatus by means of thermally conductive members arranged in the depth direction of the image pickup apparatus.

  The plurality of heat radiating plates arranged in the width direction of the imaging device are preferably arranged so as to sandwich the heat generation source. In the digital camera according to the present embodiment, the first heat radiating plate 202 and the second heat radiating plate 205 are arranged. As a result, the image pickup element 104 as a heat source and the mount unit 203 including the solenoid are sandwiched. However, the second heat radiating plate 205 can also absorb heat generated by the CPU 206a, which is a heat generation source mounted on the main board 206 existing on the back surface thereof. At this time, a plate spring 206d having a high thermal conductivity is interposed between the second heat radiating plate 205 and the CPU 206a so that the CPU 206a is not destroyed by an impact such as dropping of the digital camera.

  Further, the main board 206 on which the CPU 206a as the heat generation source is mounted is sandwiched between the second heat sink 202 and the third heat sink 208. Further, the bottom plate 204 d can be used for heat dissipation, and the mount unit 203 can be sandwiched between the bottom plate 204 d and a new heat dissipating plate provided above the mount unit 203. By providing a new heat radiating plate above the mount unit 203, this heat is efficiently absorbed by utilizing the property that the heat dissipated in the air in the housing rises without being absorbed by the other heat radiating plates. be able to.

  On the other hand, if the heat conductive member arranged in the depth direction of the imaging device can thermally connect the heat radiating plate arranged from the front surface of the imaging device and the heat radiating plate arranged from the back surface of the imaging device. Good. In the digital camera according to the embodiment of the present invention, the battery storage case is used, but the battery storage case is not necessarily required. If there is a member or the like for ensuring the rigidity in the depth direction of the imaging device, it can also be used. In the digital camera according to the embodiment of the present invention, the first heat radiating plate 202 and the second heat radiating plate 205 are thermally connected only by the battery housing case, but a plurality of heat radiating members are used to radiate a plurality of heat. A structure in which the plates are thermally connected can also be employed. Exemplifying the digital camera according to the embodiment of the present invention, a battery storage case is used to thermally connect the first heat sink 202 and the second heat sink 205 on the left side when the digital camera is viewed from the front. Then, on the right side when the digital camera is viewed from the front, a sheet metal or the like that reinforces the opening of the cover of the terminal group 206c is used to thermally connect the first heat sink 202 and the second heat sink 205. You can also.

  In this embodiment, the case where the present invention is applied to an interchangeable lens digital camera that does not include a movable mirror is illustrated. However, the present invention is a so-called single-lens reflex digital camera that includes a movable mirror. Even a digital camera that is not a lens interchangeable type can be applied.

  According to the present invention, it is possible to provide an imaging device with further improved heat dissipation efficiency, and therefore it can be applied to an imaging device such as a digital camera.
