Description

[Technical Field]

[0001] The present invention relates to an electronic device, and more particularly to a drip-proof structure for an operating member of an electronic device. [Background technology]

[0002] 2. Description of the Related Art In electronic devices such as digital cameras, various operation members such as dials, levers, and buttons can be used to set shooting conditions and select functions.

[0003] Although touch panels and other operating methods have become available in recent years, physical operating components have many advantages, such as being able to be operated blindly and being easy to operate even when wearing gloves.

[0004] On the other hand, digital cameras are electronic devices that are also expected to be used outdoors, and it is desirable for them to have a structure that prevents the intrusion of water droplets such as rain.

[0005] The dustproof and drip-proof structure of the housing often uses a structure in which an elastic material such as rubber or sponge is sandwiched into gaps to seal them.

[0006] However, in the case of an operating member, there is a range of motion for the user to operate it, and an insertion hole exists in the housing through which a detection unit passes in order to detect the state.

[0007] If the range of motion is sealed by compressing the elastic member, frictional force will become a large resistance, which may result in a loss of light operation and a clicking sensation.

[0008] If the entire circumference of the insertion opening is sealed, there is a concern that the operating section will become larger and the degree of freedom in placement will be reduced.

[0009] Furthermore, in the case of a rotary operating member, the compression direction and the operating direction are often different, and the elastic member is dragged with each repeated operation, which may gradually deteriorate and impair the drip-proof performance.

[0010] Patent Document 1 proposes a convertible PC that can be used as a tablet by rotating the keyboard 360 degrees.

[0011] A configuration has been proposed in which, when a user accidentally spills a liquid such as a drink, the liquid seeps in through the gaps in the key tops and is drained away without coming into contact with the electronic components.

[0012] By providing a drainage path below the insertion port of the drive part that raises and lowers the frame located around the keyboard, the flow path of liquid that has entered the insertion port can be controlled, preventing leakage into electronic components and allowing the liquid to be drained outside the housing.

[0013] Furthermore, since the structure does not use a rubber packing or the like to prevent fluid from entering, the operability of the key tops, which are movable parts, is not impaired. [Prior art documents] [Patent documents]

[0014] [Patent Document 1] Patent No. 6055060 Summary of the Invention [Problem to be solved by the invention]

[0015] However, since digital cameras and the like are products that are held by the user and can be tilted in various directions, it is very difficult to control the flow path of the liquid that has entered, as in the conventional configuration disclosed in Patent Document 1.

[0016] Even if it were possible to vent the moisture, if the humidity inside the housing increases, there are concerns that precision parts may corrode and that condensation may form on the viewfinder due to temperature differences.

[0017] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an electronic device that can prevent liquid from entering the housing through the insertion opening of the detection unit without impairing the operability of the rotary operation member. [Means for solving the problem]

[0018] In order to achieve the above object, an electronic device of the present invention is an electronic device having a rotary operation member that performs an operation input by rotation, and a holding part that holds the rotary operation member and has a part exposed to the exterior, the holding portion includes a wall portion covering an outer periphery of the rotation operation member, an insertion hole for inserting the rotation operation member into the housing, a convex portion covering the periphery of the insertion hole, and a first flow path surface provided between the convex portion and the wall portion, The wall portion has a cutout portion formed by removing a portion of the wall portion and having a height lower than that of the convex portion, the first flow path surface is in contact with the cutout portion, and the structure is such that liquid accumulated on the first flow path surface can be discharged from the cutout portion. [Effects of the Invention]

[0019] According to the present invention, it is possible to provide an electronic device that can prevent liquid from entering the housing through the insertion opening of the detection unit without impairing the operability of the rotary operation member. [Brief explanation of the drawings]

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In each embodiment, common elements are designated by the same reference numerals.

[0022] The embodiment described below is an example for realizing the present invention, and should be appropriately modified or changed depending on the configuration of the device to which the present invention is applied and various conditions, and the present invention is not limited to the embodiment described below.

[0023] Furthermore, parts of the embodiments described below may be combined as appropriate. [Example]

[0024] First, the basic configuration of an imaging device 100, which is an electronic device according to an embodiment of the present invention, will be described with reference to Fig. 1. Fig. 1(a) is an external perspective view of the imaging device 100 as seen from the front, and Fig. 1(b) is an external perspective view as seen from the back.

[0025] (Basic configuration of the imaging device 100) A lens mount 11 is provided on the front surface of the imaging device 100, to which various optical lenses (not shown) can be attached.

[0026] Inside the lens mount 11, an imaging element 10 and a lens communication terminal 12 for communicating with the optical lens are provided.

[0027] A still image or a moving image can be captured by forming an image of a subject on the image sensor 10 through an optical system of optical lenses.

[0028] The optical lens and the imaging device 100 communicate with each other via the lens communication terminal 12 as needed, and drive and correction of the optical lens, settings for imaging, etc. are performed.

[0029] A grip 7 is provided on the side of the imaging device 100, and the user can grip the imaging device 100 in his or her right hand and operate various operation members using the index finger and thumb.

[0030] A release switch 1 is provided on the top surface of the imaging device 100, and pressing it can command the start of capturing a still image.

[0031] The power lever 20, the mode button 21, and the upper electronic dial 22 are a group of operating members arranged coaxially. The power lever 20 is an operating member that controls the power supply of the image capture device 100. When the power lever 20 is turned on, power is supplied from a battery (not shown), and the image capture device 100 starts up.

[0032] In addition to ON and OFF, it also has a LOCK phase that disables input from the operating member, the details of which will be described later.

[0033] The upper electronic dial 22 is a rotary operation member that can change various setting values ​​and items depending on the amount of rotation. There is no limit to the rotation, and it can be rotated left and right without limit.

[0034] The mode button 21 is an operating member for changing the shooting mode, and by pressing it and then rotating the upper electronic dial 22, the shooting mode can be switched between shutter speed priority mode, aperture priority mode, and the like.

[0035] An interface unit 8 is provided on the side of the imaging device 100 opposite to the grip unit 7.

[0036] In Figure 1(a), the device is shown covered with a rubber cap, but inside the cap are various communication terminals (not shown) such as a headphone jack, microphone jack, HDMI terminal, and USB terminal.

[0037] It connects and communicates with external devices such as PCs, external microphones, and external recording devices.

[0038] A video / still image switching lever 24 is provided on the top surface near the interface unit 8. The video / still image switching lever 24 is a rotary operating member with two phases, and by rotating it, it is possible to easily switch between video shooting mode and still image shooting mode.

[0039] An electronic viewfinder 2 is provided at the top center of the rear surface of the imaging device 100.

[0040] The electronic viewfinder 2 incorporates a liquid crystal panel (not shown) as a display device and a diopter adjustment lens, and the user can check the shooting angle, focus, color, etc. by looking into the electronic viewfinder 2.

[0041] The rear LCD 3 and top LCD 4 are also display members. Similar to the electronic viewfinder 2, the rear LCD 3 can display information about captured images, various setting values, menu screens, and the like.

[0042] The top LCD 4 is a component that mainly displays the shooting mode and setting values, and when using the mode button 21, for example, the shooting mode can be switched while checking the display.

[0043] The media insertion section 5 is a slot member into which recording media such as an SD card or a CFexpress card is inserted, and is shown covered with a cover in Figure 1(b). The user can manually open the cover and insert various types of recording media into the slot (not shown) of the media insertion section 5.

[0044] (Mode button 21, upper electronic dial 22) Next, with reference to FIG. 2, the configurations of the mode button 21 and the upper electronic dial 22, which are operation members of the electronic device according to the embodiment of the present invention, will be described.

[0045] 2 is an exploded perspective view of the group of operating members including the power lever 20, the mode button 21, and the upper electronic dial 22. As shown in FIG.

[0046] The mode button 21 is slidably held by a mode button support member 213, and pressing the mode button 21 can be detected when the tip of the mode button 21 presses a metal dome switch 214 mounted on a first flexible substrate 215 located below.

[0047] An elastic sponge member 212 is provided between the mode button 21 and the upper electronic dial 22 so as to be in a compressed state, thereby reducing the gap and preventing the intrusion of dust, dirt, and water droplets.

[0048] The mode button 21 is provided with a rotation stopper shape 21 a that fits into a rotation stopper groove 213 a provided in the mode button support member 213 .

[0049] This prevents the mode button 21 from rotating around the sliding axis due to the pull of the rotation of the upper electronic dial 22.

[0050] With the above configuration, the mode button 21 can detect when pressed by the user and provides good operability. Also, because the operation surface of the mode button 21 does not rotate, problems such as characters and symbols printed on the operation surface being tilted or the operation surface rotating and causing discomfort during operation can be prevented.

[0051] The upper electronic dial 22 has a shaft portion 22a that is rotatably and slidably fitted into a dial fitting hole 202a of the base member 202.

[0052] A click cam metal plate 224 and a phase metal plate 225 are arranged below the base member 202, that is, inside the housing, and both are fixed to the underside of the shaft portion 22a of the upper electronic dial 22 by screw fastening.

[0053] The dial click ball 222 is biased by a dial click spring 223 so as to abut against the cam surface of a click cam metal plate 224 .

[0054] When a user rotates the upper electronic dial 22, the fixed click cam metal plate 224 also rotates synchronously, and the crests of the cam surface push back the dial click ball 222, and the dial click ball 222 falls into the troughs, repeating this action, giving a click feeling.

[0055] Two photointerrupters 226 mounted on the first flexible substrate 215 are arranged on the opposing surfaces of the phase metal plate 225 .

[0056] The photointerrupter 226 is a package component in which a light emitting element and a light receiving element are arranged facing each other, and can detect when an obstruction passes between them.

[0057] The phase metal plate 225, which is the shielding object in this configuration, is provided with shielding portions 225a that correspond to half of the peaks (valleys) of the click cam metal plate 224, and the amount of rotation can be counted by detecting the two states of shielding and transmission each time it passes through the photointerrupter 226.

[0058] The two photointerrupters 226 are arranged at different phases, and the rotation direction of the upper electronic dial 22 can be detected by comparing the timing at which the passage of the shielding portion 225a is detected.

[0059] With the above configuration, the upper electronic dial 22 gives a clicking sensation in response to the user's rotation operation, and it is possible to detect in which direction and by how many clicks it has been rotated.

[0060] Furthermore, since the number of clicks can be detected without contact, there is little risk of deterioration due to wear or poor contact, making it highly durable.

[0061] A first flexible board 215 on which a metal dome switch 214 and a photointerrupter 226 are mounted, and a second flexible board 206 on which a three-position switch 205, which is the detection part of the power lever 20, is mounted, are supported by a resin cover part 207.

[0062] The cover part 207 is fixed to the base member 202 by screw fastening.

[0063] Furthermore, by covering the underside of the base member 202, the cover part 207 also functions as a lid member that holds the lever click ball 203, the lever click spring 204, the dial click ball 222, and the dial click spring 223 so that they do not fall off.

[0064] (Configuration of power lever 20) Next, the configuration of the power lever 20 will be described with reference to FIGS.

[0065] FIG. 3 is a perspective view showing the appearance of the on / off lever 20 as a single component.

[0066] FIG. 4 is a perspective view of the imaging device 100 excluding the operation members of the power lever 20, the mode button 21, and the upper electronic dial 22, and shows the shape in which the operation members are attached.

[0067] FIG. 5 is a cross-sectional view of the operating members including the power lever 20, the mode button 21, and the upper electronic dial 22.

[0068] The power lever 20 has a fitting surface 20 a rotatably and slidably fitted to a lever fitting shaft 202 b of the base member 202 , and is disposed coaxially with and below the upper electronic dial 22 .

[0069] To make it easier for the user to operate the imaging device 100 from the top side, the operation unit 20b (Figures 3 and 5(b)) is shaped to protrude above the mode button 21 and upper electronic dial 22, making it easier for the user to place their fingers on it.

[0070] As shown in Figure 3, a click cam surface 20c and a phase detection leg 20d are provided at the bottom of the power lever 20, and in order to insert these into the inside of the housing, an insertion hole 202c is provided at the opposing position of the base member 202 shown in Figure 4.

[0071] The insertion opening 202c is opened in a range that takes into consideration the movable angle so that the click cam surface 20c of the power lever 20 and the phase detection leg 20d do not interfere with each other.

[0072] A convex shape 202d is provided around the entire periphery of the insertion opening 202c for drip-proofing, the function of which will be described in detail later.

[0073] FIG. 5(b) is a cross-sectional view of the operating member group shown in FIG. 5(a) taken along line AA.

[0074] A lever click ball 203 is disposed below the base member 202 and is biased by a lever click spring 204 so as to come into contact with a click cam surface 20 c provided in the radial direction of the power lever 20 .

[0075] When a user rotates the power lever 20, the click cam surface 20c rotates, and the crest of the click cam surface 20c pushes back the lever click ball 203, and the lever click ball 203 falls into the trough, repeating this action to give a click feeling.

[0076] Although not shown in FIG. 5(b), the phase detection leg 20d is also inserted into the housing and is positioned so that the detection portion 205a of the three-position switch 205 mounted on the second flexible substrate 206 is engaged.

[0077] (Phase and detection when power lever 20 is operated) Next, with reference to FIG. 6, the phase and detection when the power lever 20 is operated will be described.

[0078] 6(a) to 6(c) are top views of the power lever 20 at each operation phase, and FIGS. 6(d) to 6(f) are bottom views showing the state of the click cam surface 20c and the phase detection leg 20d at each operation phase of the power lever 20.

[0079] The bottom surface is normally covered by a cover part 207, but for the sake of explanation, the cover part 207 is shown removed.

[0080] FIG. 6(a) shows the state in which the operating portion 20b of the power lever 20 is rotated to the left end, which indicates the power OFF state.

[0081] FIG. 6(d) shows the internal state in the power-off state, with the detection portion 205a of the three-position switch 205 being tilted to the left in the drawing by the phase detection leg 20d of the power lever 20.

[0082] The lever click ball 203 is biased by a lever click spring 204 to the valley portion at the right end of the click cam surface 20c.

[0083] This maintains the phase of the power lever 20 and fixes it so that it does not move inadvertently when no operating force is applied.

[0084] FIG. 6(b) shows the state in which the operating part 20b of the power lever 20 is rotated 15 degrees to the right, which represents the LOCK state.

[0085] The LOCK state is a state in which the power is on but input from specific operating members is not accepted, and is used to prevent erroneous operation during shooting and when you want to use the camera with fixed settings.

[0086] FIG. 6(e) shows the internal state in the LOCK state, where the detection section 205a of the three-position switch 205 is at the center phase of the phase detection leg 20d.

[0087] Similarly, the lever click ball 203 moves to the central valley of the click cam surface 20c and is held there by the bias of the lever click spring 204.

[0088] FIG. 6(c) shows the state in which the operating part 20b of the power lever 20 has been rotated 30 degrees to the right from the state in FIG. 6(a), and represents the power-on state.

[0089] Unlike the LOCK state in FIG. 6(b), this is a state in which all operating members are functional.

[0090] FIG. 6(f) shows the internal state in the ON state, where the detection portion 205a of the three-position switch 205 is tilted to the right in the figure by the phase detection leg 20d of the power lever 20.

[0091] The lever click ball 203 moves to the valley at the left end of the click cam surface 20c and is held there by the bias of the lever click spring 204.

[0092] The phase and internal state when the on / off lever 20 is operated have been described above with reference to Fig. 6. The on / off lever 20 can be switched between and maintained in three phases: OFF, LOCK, and ON, and the phase can be detected by tilting the detection section 205a of the three-position switch 205 accordingly.

[0093] (Power lever 20 clearance and waterproof function) Next, the clearance relationship and drip-proof function of the power lever 20, which is an operating member of the electronic device according to the embodiment of the present invention, will be described with reference to FIGS. 4, 5(d) and 7. FIG.

[0094] The peripheral shape of the on / off lever 20 will be described with reference to FIG.

[0095] The periphery of the power lever 20 is covered with a wall shape SS formed by the base member 202, and only on the back side is a notch K where the wall shape SS has been removed.

[0096] The base member 202 that holds the operation member group has a flow channel surface SH and a flow channel surface SL that serve as the discharge flow channel surfaces for water droplets.

[0097] As shown in FIG. 7, the flow passage surface SH, which is the movable range of the on / off lever 20, is largely exposed to the outside.

[0098] For example, when water droplets fall due to rain, it is expected that a large amount of water will flow into the flow path surface SH, which has a large exposed area, and since it is located higher than the flow path surface SL, the water will flow as shown by the arrow F1 in Figure 4.

[0099] By creating a difference in elevation on the flow path surface and covering the surrounding area with a wall shape SS, a water flow can be created that flows toward the cutout part K, which serves as the outlet.

[0100] Next, the gap relationship between the on / off lever 20 and the surrounding shape will be described with reference to Fig. 5(d). Fig. 5(c) is a cross-sectional view taken along line BB in Fig. 5(a), and Fig. 5(d) is an enlarged view of range C in Fig. 5(c).

[0101] The power lever 20 forms a clearance L1 in the radial direction with the wall shape SS that covers the outer periphery.

[0102] The convex shape 202d of the base member 202 is provided so as to protrude higher than the flow path surface SL.

[0103] The on / off lever 20 is shaped to cover the convex shape 202d, and a clearance L2 is formed in the radial direction between the on / off lever 20 and the outer circumferential surface of the convex shape 202d.

[0104] The clearance L2 is set to be narrower than the clearance L1, and when a liquid W flows in as shown in FIG. 5(d), for example, the narrower clearance L2 provides greater resistance to the intrusion of water due to surface tension.

[0105] The clearance L3, which is located inside the clearance L2 and is formed in the thrust direction by the on / off lever 20 and the upper surface of the convex shape 202d, is narrower than the clearance L2, resulting in a structure in which the resistance gradually increases. Therefore, the liquid W that has flowed in does not penetrate into the housing, but is easily able to flow into the gap between the on / off lever 20 and the wall shape SS.

[0106] FIG. 7 shows a part of the top surface of the imaging device 100, and illustrates the drainage path of water droplets around the power lever 20.

[0107] As mentioned above, it is assumed that water droplets flow in mostly from the flow path surface SH, which has a large exposed area, and after flowing down to the flow path surface SL, they pass between the power lever 20 and the wall shape SS and head toward the cutout portion K, which is the outlet.

[0108] At this time, the path F2 leading to the discharge and the operating direction F3 of the power lever 20 are coaxial rotation directions, so that even when the power lever 20 is operated with water droplets accumulated in the gap, the water pushed out by the power lever 20 is properly discharged without heading toward the insertion opening 202c of the base member 202.

[0109] The drip-proof structure of the power lever 20 of the imaging device 100, which is an electronic device according to an embodiment of the present invention, has been described above.

[0110] By providing a convex shape 202d around the insertion hole 202c of the base member 202, and by providing a wall shape SS surrounding the power lever 20 and a notch K serving as a drainage hole, it is possible to prevent liquid from entering the housing.

[0111] Furthermore, since the intrusion of liquid is prevented by controlling the flow path rather than sealing by compression using an elastic member, the operability is not impaired.

[0112] The features of the embodiments of the present invention described above are summarized below.

[0113] The first aspect of the invention will be described with reference to FIGS. 4, 5b, 5c, 5d, and 7. FIG.
