Description

Technical Field

[0001] The present disclosure relates to an electronic device.

Background Art

[0002] In recent years, in imaging devices, due to the increase in brightness and resolution of liquid crystal panels, the power consumption of liquid crystal panels and backlights has been increasing. In addition, conventionally, with an emphasis on the performance and cost of liquid crystal panels, there are many configurations in which a liquid crystal panel and a touch panel are purchased separately and used in combination. In the case of this configuration, from the viewpoint of assembly cost, a structure is often adopted in which an air layer is provided between the liquid crystal panel and the touch panel.

[0003] In a configuration in which an air layer is provided between the liquid crystal panel and the touch panel, due to the increase in power consumption of the liquid crystal panel and the backlight, a temperature difference occurs between the liquid crystal panel and the touch panel, and dew condensation may occur on the glass provided on the back surface of the touch panel. When dew condensation occurs, it becomes difficult to visually recognize the screen of the liquid crystal panel, which is a disadvantage to the user. In addition, once dew condensation occurs, it does not disappear until the temperature of the surface of the touch panel rises. Therefore, the user needs to wait for shooting until the display of the liquid crystal panel can be visually recognized and used. In particular, in a small liquid crystal panel mounted on an imaging device such as a video camera, since there are size limitations, it is also difficult to take measures against dew condensation such as mounting a fan in the liquid crystal panel unit.

[0004] Patent Document 1 discloses a technique for guiding heat generated from a heat source inside the housing of an imaging device to the glass surface on the front surface of a lens provided in the same housing to prevent dew condensation.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In Patent Document 1, since the glass surface to be protected from condensation is formed of the same housing as the imaging device main body, it is possible to guide the heat inside the housing to the glass surface by means of a duct. However, when the condensation prevention target is configured separately from the device main body, there is a problem that heat cannot be guided to the condensation prevention target by the duct arranged inside the device main body.

[0007] The present disclosure has been made in view of the above problems, and an object thereof is to provide an electronic device that can quickly eliminate condensation generated on the display surface of a display unit configured separately from the device main body and shorten the waiting time until the display unit can be used.

Means for Solving the Problems

[0008] The electronic device of the present disclosure includes a device main body, a display unit movably connected to the device main body and having a display surface, and a heat radiating unit for radiating heat generated inside the device main body to the outside, and the display unit is movable to a position where the display surface faces the heat radiating unit.

Effects of the Invention

[0009] According to the present disclosure, an electronic device is realized that can quickly eliminate condensation generated on a display unit configured separately from the device main body and shorten the waiting time until the display unit can be used.

[0011] [Basic Configuration and Functions of Image Display Devices in Embodiments] Specifically, when disclosing the embodiments, the basic configuration and functions of the electronic devices in the embodiments will be described.

[0012] The electronic device according to the present disclosure is, for example, an imaging device, and includes a device main body and a display unit that is movably connected to the device main body and has a display surface for displaying images, characters, various setting information, and the like. A heat radiation part for radiating heat generated inside the device main body to the outside is provided in the device main body. The heat radiation part is, for example, an exhaust port provided on the exterior of the device main body. In the electronic device according to the present disclosure, the heat radiated from the heat radiation part to the outside of the device main body is used to remove dew condensation generated on the display unit. That is, the display unit is movable to a position where the display surface faces the heat radiation part, and by moving the display unit to that position and warming the display surface with the heat radiated from the heat radiation part, the dew condensation generated on the display unit is removed. In this way, with a simple method, the dew condensation on the display unit is eliminated early, and the waiting time until the display unit can be used is shortened.

[0013] In the electronic device of the present disclosure, the display unit is separate from the device body, and a connection mechanism is provided that connects the display unit to the device body and enables the display unit to be movable to at least two different positions, including a position where the display surface faces the heat dissipation part. It is preferable that the position where the display surface of the display unit faces the heat dissipation part also serves as the position where the display unit is housed with respect to the device body, which is convenient for the user. Other positions of the display unit include the position where the user uses the display unit, for example, in the case of an imaging device, the shooting position and the setting position for inputting characters and various information.

[0014] The electronic device of the present disclosure is provided with a mechanism for dissipating heat from the heat dissipation part. As a specific example of the heat dissipation mechanism, a mechanism having a cooling fan for transferring the heat generated inside the device body and a duct for guiding the heat transferred by the cooling fan to the heat dissipation part is preferable. Together with this heat dissipation mechanism, a position detection unit for detecting whether the display surface of the display unit is in a position facing the heat dissipation part may be provided. The heat dissipation mechanism adjusts the operation of the cooling fan based on the detection result by the position detection unit. When it is determined by the position detection unit that the display surface is in a position facing the heat dissipation part, for example, the dew condensation on the display unit can be quickly removed by increasing the rotation speed of the cooling fan.

[0015] As another specific example of the heat dissipation mechanism, a mechanism in which the heat dissipation part is a part of the exterior of the device body and has a heat conduction member for transferring the heat generated inside the device body to a part of the exterior can be considered. In this case, heat can be dissipated from the exterior of the device body without providing a structure such as an exhaust port in the device body, and dew condensation on the display unit can be removed with a simple configuration.

[0016] Also, in the electronic device of the present disclosure, it is preferable to form a closed space at the facing position between the heat dissipation part of the device body and the display surface of the display unit when removing dew condensation. Specifically, when the display unit moves to a position where the display surface and the heat dissipation part face each other, a closed space is formed at the position where the display surface and the heat dissipation part face each other. By forming a closed space at this position, the heat released from the heat dissipation part stays in the closed space without immediately escaping to the outside air, and the display surface can be efficiently warmed to quickly and surely eliminate dew condensation.

[0017] Here, in order to form a closed space, for example, a first convex portion is arranged on the display surface of the display unit, and a second convex portion is arranged on the exterior of the device body. When the display unit moves to a position where the display surface and the heat dissipation unit face each other, the first convex portion abuts on the exterior of the device body, and the second convex portion abuts on the display surface, and the first convex portion and the second convex portion are combined to form a frame-shaped member. At this time, a substantially closed space surrounded by the display surface, the heat dissipation unit provided on the device body, and the frame-shaped member is formed. In this configuration, when the display unit is not placed at a position for dew condensation elimination, for example, when it is inverted and the back surface opposite to the display surface of the display unit faces the heat dissipation unit, since the first convex portion is not located at the opposing portion and only the second convex portion exists, a closed space is not formed. Therefore, heat does not stay at the opposing portion, and it is possible to efficiently dissipate heat inside the device body.

[0018] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Note that in the following embodiments, the invention according to the claims is not limited. Although a plurality of features are described in the embodiments, not all of these plurality of features are essential to the invention, and the plurality of features may be arbitrarily combined.

[0019] [First Embodiment] Hereinafter, an imaging device which is an electronic device according to the first embodiment will be described in detail with reference to the drawings.

[0020] [Configuration of Imaging Device]< First, the configuration of the imaging device 100 will be described with reference to FIGS. 1 and 2. In order to simplify the following description, an XYZ coordinate system is defined as follows.

FIG. 2 is a perspective view showing the internal components of the imaging device 100, (a) is a front perspective view of the imaging device 100, and (b) is a rear perspective view of the imaging device 100.

[0022] As shown in FIG. 1, the imaging device 100 includes a device body 102 and a lens 103. The device body 102 has, inside thereof, a control circuit board 110 that controls the entire imaging device 100, an imaging element 116 that converts the light incident from the lens 103 into an electrical signal, a power supply unit (not shown), a recording unit for recording images, and various operation units and the like. These components perform the main functions of the imaging device. And, as shown in FIG. 1(a), the lens 103 is attached to the imaging device 100 on the side of the subject to be photographed (+Z direction) and can be exchanged according to the shooting situation.

[0023] As shown in FIG. 1(a), on the left side (-X direction) of the device body 102, there are an air intake port 105 for sucking cool outside air into the body by a forced air cooling mechanism using a cooling fan 113 described later, and operation units 311 such as a release switch and a mode dial.

[0024] As shown in FIG. 1(b), on the right side (+X direction) of the device body 102 as viewed from the subject side, there is an exhaust port 104 for discharging the hot air inside the body to the outside by a forced air cooling mechanism using a cooling fan 113 described later. Also, on the right side (+X direction) of the device body 102, a display unit 107 for checking the captured video is movably connected, and a rotation detection unit (not shown) is mounted inside a rotation mechanism 210 which is a connection mechanism, and an open / close detection unit (not shown) is mounted inside the imaging device body 102.

[0025] The display unit 107 is provided with a touch panel 200 for checking the captured image and inputting to the apparatus main body 102, and the touch panel 200 is configured to form a part of the exterior of the display unit 107. Further, a first convex portion 201 is provided on at least one side of the outer periphery of the touch panel 200, and the imaging apparatus main body 102 has a second convex portion 202 at a position surrounding the outer periphery of the touch panel 200 at a first position which is a dew condensation elimination position described later for the display unit 107. The second convex portion 202 may be constituted by the exterior of the imaging apparatus main body 102, or may be constituted by using a cushioning material or the like.

[0026] <Internal components of the apparatus main body> The internal components of the imaging apparatus main body 102 will be described with reference to FIGS. 2 and 3. FIG. 3 is an exploded perspective view showing the internal components of the imaging apparatus 100. As shown in FIGS. 2 and 3, inside the apparatus main body 102, a control circuit board 110, a first duct 111, a second duct 112, a cooling fan 113, an imaging element board 115, and an imaging element 116 are provided. A heat dissipation mechanism is constituted including the first duct 111, the second duct 112, and the cooling fan 113. In this embodiment, only the components related to the present invention are described, and the description of other components is omitted.

[0027] An element 117 serving as a heat source is mounted on the control circuit board 110 that controls the functions of the imaging apparatus main body 102. The first duct 111 is connected to the intake side (+Z direction) of the cooling fan 113, and the second duct 112 is connected to the exhaust side (+X side) of the cooling fan 113. The cooling fan 113 is a so-called centrifugal fan, and is configured to discharge the air sucked from the surface direction in the centrifugal (side surface) direction. Here, the imaging apparatus 100 is configured to take in air from the intake port 105 described above by the rotation of the cooling fan 113, and discharge the air from the exhaust port 104 via the cooling fan 113 to dissipate heat.

[0028] FIG. 4 is a block diagram showing the system configuration of the imaging apparatus 100 according to the present embodiment. The system control unit 310 is mounted on the control circuit board 110 and is composed of a microcomputer or the like having a ROM, a RAM, an A / D converter, a D / A converter, and a built-in memory. Further, the system control unit 310 has an image processing unit 310a that performs necessary signal processing on the captured image data.

[0029] An operation unit 311 such as a release switch and a mode dial is connected to the system control unit 310. The display unit 107 incorporates a liquid crystal panel 108, a backlight 109 that illuminates from the back of the liquid crystal, and a touch panel 200 that performs input by a touch sensor. Further, a position detection unit having an open / close detection unit 212 and a rotation detection unit 211 for detecting the position of the display unit 107 is provided. The open / close detection unit 212 detects the opening and closing of the display unit 107, and the rotation detection unit 211 detects the rotation of the display unit 107, and outputs respective detection signals to the system control unit 310. The system control unit 310 acquires the detection signals output by the open / close detection unit 212 and the rotation detection unit 211, and determines the position of the display unit 107. Thereafter, display control of the display unit 107, operation control of the image processing unit 310a, and control of the cooling fan 113 are performed.

[0030] <Explanation of the dew condensation elimination structure of the touch panel> Using FIG. 5, a method for eliminating dew condensation on the touch panel 200 provided in the display unit 107 will be described. In FIG. 5, (a) is a rear view of the imaging device main body 102 when the display unit 107 is in the first position (dew condensation elimination position), and (b) is a cross-sectional view taken along the dashed-dotted line X-X in (a).

[0031] The touch panel 200 provided in the display unit 107 faces the exhaust port 104 of the device main body 102 and has a positional relationship in which at least a part overlaps in the projection in the X direction. As shown in FIG. 5(b), 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 back surface (-Z direction) of the control circuit board 110. The intake port 105 of the imaging device main body 102 is connected to the first duct 111, and the exhaust port 104 is connected to the second duct 112.

[0032] The cooling fan 113 takes in outside air as indicated by the arrow from the air intake 105, and air flows through the first duct 111. Then, the cooling fan 113 sucks in the air that has passed through the first duct 111 as indicated by the arrow, and exhausts the air sucked in by the cooling fan 113 to the second duct 112. The warmed air that has passed through the second duct 112 is discharged outside the apparatus main body 102 as indicated by the arrow from the exhaust port 104.

[0033] Here, the first duct 111 and the second duct 112 are made of a metal material with high thermal conductivity, and fins (not shown) may be erected in their respective flow paths to improve heat exchange with air. Also, the first duct 111 and the second duct 112 may be integrally formed.

[0034] At least one or more elements 117 are mounted on the control circuit board 110. The element 117 is an element that requires a large amount of power, such as an image processing engine. The heat generated by the high-power-consuming element 117 is transferred to the first duct 111 via the heat conduction member 119. The heat conduction member 119 is, for example, a heat-dissipating rubber with high thermal conductivity. The air that has been heated by transferring heat in the first duct 111 is discharged from the exhaust port 104, and is configured to hit the surface of the touch panel 200 located at a position facing the exhaust port 104.

[0035] In the imaging apparatus 100, a first convex portion 201 is provided on the touch panel 200 which is the display surface of the display unit 107, and a second convex portion 202 is provided on the exterior of the apparatus main body 102. In the present embodiment, the first convex portion 201 is linear and the second convex portion 202 is U-shaped so as to form a rectangular shape when combined. The second convex portion 202 is arranged on the exterior of the apparatus main body 102 so as to include the exhaust port 104 which is a heat radiating portion.

[0036] When the display unit 107 moves to the first position where the dew condensation is eliminated, the first convex portion 201 provided on the display unit 107 and the second convex portion 202 provided on the apparatus main body 102 are combined to form a frame-shaped member. At this time, a substantially closed space is formed by the touch panel 200, the portion including the exhaust port 104 of the exterior of the apparatus main body 102, and the frame-shaped member. By forming the closed space, the warmed air discharged from the exhaust port 104 stays in the closed space without immediately escaping to the outside air, and the surface of the touch panel 200 can be efficiently warmed. That is, by efficiently applying the air warmed inside the apparatus main body 102 to the touch panel 200 to warm it, it becomes possible to quickly eliminate the dew condensation generated inside the touch panel 200a.

[0037] Next, the flow of the air discharged from the exhaust port 104 when the display unit 107 is in a predetermined position, the display content of the display unit 107, and the control of the cooling fan 113 and the control circuit board 110 will be described with reference to FIGS. 6, 7, and 8. The predetermined positions include a first position (dew condensation elimination position), a second position (use state), and a third position (inverted storage position).

[0038] In FIG. 6, (a) is a top view of the imaging apparatus 100 when the display unit 107 is in the first position (dew condensation elimination position), (b) is a cross-sectional view taken along the dashed-dotted line A-A in (a), and (c) is a side view showing the display surface of the display unit 107. In FIG. 7, (a) is a top view of the imaging apparatus 100 when the display unit 107 is in the second position (use state), and (b) is a cross-sectional view taken along the dashed-dotted line B-B in (a). In FIG. 8, (a) is a top view of the imaging apparatus 100 when the display unit 107 is in the third position (inverted storage position), (b) is a cross-sectional view taken along the dashed-dotted line C-C in (a), and (c) is a side view for explaining the display surface of the display unit 107.

[0039] Figure 6(b) shows the state near the exhaust port 104 at the first position (dew condensation elimination position). The arrows in the figure represent the air flow. At the first position, the first convex portion 201 of the display unit 107 and the second convex portion 202 of the apparatus main body 102 are combined to form a frame-shaped member, and a substantially closed space is formed. At this time, the warmed air discharged from the exhaust port 104 is supplied into the closed space formed by the frame-shaped member so as to hit the surface of the touch panel 200. By the air remaining in the closed space, the temperature of the surface of the touch panel 200 is efficiently increased.

[0040] Here, as shown in FIG. 6(c), when the display unit 107 is in the first position, since there is no need to display an image on the display unit 107, a white screen or the like is displayed. At this time, it is preferable to increase the temperature of the inside 200a of the touch panel by adjusting the backlight 109 disposed behind the liquid crystal panel 108 to a high brightness. Further, in order to discharge warmer air from the exhaust port 104, the rotational speed of the cooling fan 113 may be increased, or the power consumption of the element 117 mounted on the control circuit board 110 may be increased.

[0041] Figure 7(b) shows the state near the exhaust port 104 at the second position (use state). At the second position, since the touch panel 200 of the display unit 107 is open, the warmed air discharged from the exhaust port 104 is immediately released into the outside air. On the display unit 107, characters such as "normal use mode" are displayed together with the captured image. Further, in order to set the power consumption of the apparatus main body 102 to the normal use value, the rotational speed of the cooling fan 113 and the power consumption of the element 117 are controlled to the normal use values.

[0042] FIG. 8(a) shows the state near the exhaust port 104 at the third position (inverted storage position). At the third position, the touch panel 200 provided with the first convex portion 201 on the surface faces outward, and only the second convex portion 202 is located at the opposing portion with the back surface of the display portion 107 of the apparatus main body 102. At this time, the warmed air discharged from the exhaust port 104 hits the surface of the exterior cover 230 located at the position facing the touch panel 200 on the back surface of the display portion 107, and is discharged from the open portion above the second convex portion 202 in the apparatus main body 102. Therefore, heat does not stay in the control circuit board 110 etc. of the apparatus main body 102, and cooling of the element 117 etc. by the cooling fan 113 is possible.

[0043] Here, when dew condensation has occurred on the display portion 107, as shown in FIG. 8(c), a message for prompting movement to the first position (dew condensation elimination position), for example, "Please invert the panel to eliminate dew condensation" etc. is displayed. Also, in order to avoid warming the exterior cover 230 and increasing dew condensation, the system control unit 310 adjusts the rotation speed of the cooling fan 113 to a low speed and controls the power consumption of the element 117 to the value during normal use. Also, the second convex portion 202 disposed on the apparatus main body 102 can serve as a receiving portion in the -X direction for suppressing rattling of the display portion 107 when performing an input operation on the touch panel 200 at the third position (inverted storage position).

[0044] As described above, in the imaging apparatus 100 according to the present embodiment, the heat generated inside the apparatus main body 102 is utilized to apply the air warmed inside to the surface of the touch panel 200. Thereby, the surface temperature of the touch panel 200 rises, and the inner side 200a of the touch panel can reach the dew point earlier. That is, it becomes possible to eliminate the dew condensation generated on the inner side 200a of the touch panel at an early stage.

[0045] [Second Embodiment] Hereinafter, an imaging device which is an electronic device according to the second embodiment will be described in detail with reference to the drawings. In this embodiment, since only the heat radiating portion and the heat radiating mechanism of the imaging device are different from those of the first embodiment, the heat radiating portion and the heat radiating mechanism will be described here.

[0046] FIG. 9 is a schematic diagram showing the imaging device 500 according to this embodiment, where (a) is a rear view and (b) is a cross-sectional view taken along the dashed-dotted line K-K of (a). Inside the apparatus main body 102, a heat radiating mechanism having heat conducting members 119 and 511 that transfer heat generated inside to a part of the exterior is provided. In this case, a part of the exterior of the apparatus main body 102 serves as the heat radiating portion 512. Specifically, one end of a heat conducting member 511 capable of heat transfer such as a heat pipe is thermally connected to an element 117 mounted on the control circuit board 110 by a heat conducting member 119 such as a heat sink sheet. The other end of the heat conducting member 511 is connected to the heat radiating portion 512 of the apparatus main body 102.

[0047] In the above heat radiating mechanism, the heat conducting member 511 can transfer the heat generated from the element 117 to the heat radiating portion 512 provided on the exterior of the imaging device 500. The heat transferred to the heat radiating portion 512 is released from the exterior side of the heat radiating portion 512 to the outside of the apparatus main body 102.

[0048] The heat radiated from the heat radiating portion 512 can warm the surface of the touch panel 200 of the display portion 107 at the first position (dew condensation elimination position) facing the heat radiating portion 512. Thereby, it is possible to eliminate the dew condensation inside the touch panel 200a by raising the temperature of the surface of the touch panel 200.
