The axis P (second rotation axis) is the center of rotation of the pan unit 30 with respect to the base unit 20 in the pan direction. The axis T (first rotation axis) is the rotation center of the tilt unit 40 in the tilt direction with respect to the pan unit 30. The axis P and the axis T are orthogonal to each other. As described above, in the electronic device 100, the base unit 20 and the pan unit 30 are arranged vertically. The tilt unit 40 has a lens unit 50 and is rotatable around an axis T with respect to the pan unit 30. That is, the lens unit 50 is rotatable around each of the axis T and the axis P. With such a configuration, the electronic device 100 can rotate the lens unit 50 in the pan direction and the tilt direction, which are rotation directions of two axes orthogonal to the base unit 20. For this reason, imaging | photography of various directions and angles is attained.

  The tilt unit 40 including the lens unit 50 includes three units of a right cover (first cover) 320, a left cover (second cover) 321, and a lens cover (third cover) 322 formed of a transparent member.

The left cover 321 covers the left side surface (second side surface) of the lens unit 50. The lens cover 322 covers the front of the lens unit 50. Further, the exterior member protects a tilt drive unit 350 and a tilt position detection unit 360 which will be described later. The electronic device 100 includes a tilt unit 40 including a lens unit 50 protected by the exterior member, a pan unit 30, and a base unit 20. The pan unit 30 has a pan base 310 and a pan rotary plate 330. The base unit 20 has a base cover 210, a control substrate 220 and a bottom cover 230.

  The electronic device 100 is provided with a wireless communication unit (not shown) inside thereof. The wireless communication unit enables wireless operation from an external device. For example, by performing wireless communication with an electronic device such as a smartphone, it is possible to perform wireless operations such as remote shooting with the electronic device 100 and transfer of a moving image acquired by the electronic device 100. The control board 220 is mounted with a CPU that performs image processing, a memory, and the like. In addition, the control board 220 is mounted with a driver IC that performs drive control of the pan unit 30 and the tilt unit 40. A flexible printed circuit (FPC) 231 and a recording unit (not shown) are mounted on the bottom cover 230. Specifically, the recording unit is a printed circuit board mounted with a connector capable of accommodating a card type nonvolatile memory, and is electrically connected to the control substrate 220 through the FPC 231. The electronic device 100 can record an image by writing the image data generated by the control board 220 into the card-type nonvolatile memory mounted in the recording unit.

  Bundles 51 extending from the lens unit 50 are electrically connected to the control substrate 220. Specifically, the bundle 51 includes a plurality of electric wires in which the core wire of the conductor is covered with an insulator, a connector connected to both ends of the electric wires, and an adhesive tape for bundling the electric wires over a predetermined length. It is configured. The electric wire used for the bundle wire 51 may adopt a coaxial cable configured of an inner conductor, an insulator, an outer conductor, and a protective coating, as necessary.

  The pan base 310 includes a pan chassis 311 formed by pressing a plate-like metal, a pan base 312 made of resin, and a blind member (fastening member) 370 of the bundle wire 51. The pan chassis 311 is a support member that rotatably supports the lens unit 50 about the axis T. The pan base 312 is a holding member that holds the pan chassis 311. The blind member 370 is a component for making it difficult to see at least a part of the inner bundle line 51 which can be seen from the lens cover 322 which is a transparent exterior. The pan chassis 311 and the blind member 370 are fixed to the pan base 312 by screws (not shown).

  The right cover 320 and the left cover 321 are fixed by screws 380 a to 380 d from the direction parallel to the axis P (third direction) via the pan base 312. As described later, when the screws 380a to 380d for fixing the right cover 320 and the left cover 321 are viewed from the third direction, an area including the lens unit 50, the tilt drive unit 350, and the tilt position detection unit 360. Provided within the range (projected range) of

  The tilt unit 40 is respectively fitted in a pair of rotation support holes (bearings) 311 a provided in the pan chassis 311 by the tilt shaft portions 40 a provided on the side surfaces of the tilt unit 40. After the tilt shaft portion 40a is fitted, the rotation support hole 311a is fastened to the pan chassis 311 by a screw. Thereby, the tilt unit 40 is supported so as to be rotatable in the tilt direction about the axis T with respect to the pan base 310. Further, the pan unit 30 including the tilt unit 40 is fitted to the rotation support hole (bearing portion) 210 a provided in the base cover 210 with the pan shaft 312 a of the pan base 312. Then, the pan rotary plate 330 having an annular shape is fastened to the pan base 312 by the screw 340 from the inside of the base cover 210. Thus, the pan unit 30 is supported rotatably in the pan direction about the axis P with respect to the base cover 210. The elastic member 325 is disposed between the pan base 312 and the right cover 321 and between the pan base 312 and the left cover 320 to prevent water immersion to the inside of the electronic device 100.

  Next, with reference to FIG. 3, a configuration of an actuator for causing the tilt unit 40 to be rotationally driven about the axis T in the tilt direction and a configuration of a detection unit that detects the rotational position of the tilt unit 40 will be described. FIG. 3 is an exploded perspective view of the pan unit 30, and shows a state in which the tilt unit 40 is incorporated into the pan unit 30. FIG. 3A and 3B respectively show the pan unit 30 (tilt unit 40) from different viewpoints.

  In FIGS. 3A and 3B, the pan chassis 311 has a flat portion where it is fastened to the pan base 312 by a screw (not shown), and a pair of arm portions 311c having flat surfaces perpendicular to the flat portion. It consists of A blindfold member 370 is provided at a flat portion of the pan chassis 311. A rotation support hole 311 a rotatably supporting the tilt unit 40 is formed at the tip of the arm 311 c. The rotation support hole 311 a is formed by injection molding of a resin (for example, polyacetal (POM) or the like) which is low in friction and excellent in slidability. However, the rotation support hole 311 a is not limited to the resin material, and a rolling bearing such as a ball bearing or a roller bearing may be adopted. The tilt rotary plate 41 is fixed to one side surface of the tilt unit 40 by a screw, and has an integral structure. Then, on the other side surface of the tilt unit 40, a tilt reflection scale 42 is affixed and fixed with a double-sided tape (not shown). In a state where the tilt rotary plate 41 and the tilt reflection scale 42 are fixed to the tilt unit 40, the tilt shaft portion 40a is fitted in the rotation support hole 311a and held rotatably around the axis T.

  An opening 311 d is formed at the bottom of the pan chassis 311. An opening 311e and an opening 311f are formed in the arm 311c. A tilt drive unit (drive unit) 350 and a tilt position detection unit (position detection unit) 360 are fixed to the arm 311 c of the pan chassis 311. The tilt drive unit 350 drives the tilt unit 40 to rotate the lens unit 50. That is, the tilt drive unit 350 drives the lens unit 50 to rotate about the axis T. The tilt position detection unit 360 detects the rotation of the tilt unit 40 and detects the position of the lens unit 50. That is, the tilt position detection unit 360 detects the position of the lens unit 50 driven by the tilt drive unit 350. The tilt drive unit 350 is disposed to enter the inside of the opening 311 e provided in the arm 311 c of the pan chassis 311. The tilt position detection unit 360 is arranged to intrude inside the opening 311 f.

  The tilt drive unit 350 is an actuator called a general ultrasonic motor (vibration type motor) of a method of driving a driven body by using ultrasonic vibration. The ultrasonic motor needs to be held down by a constant pressure in order to transmit ultrasonic vibration to a driven body by a component called a vibrator. The mechanism will be described below. The tilt drive unit 350 includes a tilt drive unit 351, a felt 352, a presser 353 formed of resin, a spring 354, and a case 355.

  FIG. 4 is an exploded perspective view of the tilt drive unit 351. As shown in FIG. In FIG. 4, the vibrator 351 a is in pressure contact with the tilt rotary plate 41 of the tilt unit 40. The piezoelectric element 351 b applies ultrasonic vibration to the vibrator 351 a. The FPC 351 c is a wiring material which is bonded and fixed to the piezoelectric element 351 b and applies a high frequency voltage to the piezoelectric element 351 b, and is a so-called flexible printed circuit (FPC). The base member 351d holds these components together. The tilt drive unit 351 is a composite component combining these. Note that the FPC 351c is drawn by extracting only the necessary outer shape, and unnecessary portions are omitted in the description.

  The FPC 351c constituting the tilt drive unit 351 is directly connected to the control substrate 220 shown in FIG. 2, receives a control signal from the driver IC, and applies a predetermined high frequency voltage to the piezoelectric element 351b. The vibrator 351a has a plurality of contact points 351e. When a high frequency voltage is applied to the piezoelectric element 351b, vibration corresponding to the frequency is excited in the vibrator 351a. By controlling this vibration, the vibrator 351a and the tilt rotary plate 41 can be moved relative to each other, so that the tilt unit 40 can be moved relative to each other.

  Further, in the tilt drive unit 350 shown in FIGS. 3A and 3B, it is preferable that the plurality of contact points 351e provided on the vibrator 351a be uniformly pressed against the tilt rotary plate 41. . Therefore, as shown in FIG. 3A, the spring 354 of the tilt drive unit 350 presses the tilt drive unit 351 via the felt 352 and the presser 353. The presser 353 is disposed inside the base member 351 d of the drive unit 351, is slidable in a direction parallel to the axis T, and plays a role of transmitting the pressure of the spring 354 as a wide range of surface pressure. The felt 352 is disposed between the presser 353 and the drive unit 351, and plays a role as a damping material that prevents the vibration generated by the vibrator 351a from being transmitted to the presser 353 or the spring 354 side.

  As shown in FIGS. 3A and 3B, the drive unit 351, the felt 352, the presser 353, and the spring 354 are disposed so as to overlap between the case 355 and the tilt unit 40. . Therefore, by fixing the case 355 to the arm portion 311 c with a screw, the pressurized state can be uniformly maintained. Thus, the driven body of the ultrasonic motor always receives a constant pressure. Considering stable drive control and durability, high smoothness and wear resistance are required on the surface with which the contact point 351e of the vibrator 351a contacts. Therefore, in order to form a smooth flat surface, the surface processing such as lapping is applied to the friction sliding surface 41 a which is a flat surface where the contact point 351 e contacts the tilt rotation plate 41. Further, by employing a stainless steel material as the material of the tilt rotary plate 41 and performing a hardening process on the friction sliding surface 41 a by a nitriding process or the like, high flatness and wear resistance can be obtained. However, in order to obtain flatness and wear resistance, it is not limited to the above-mentioned processing method, for example, in order to obtain wear resistance, carbon is added to the surface of the friction sliding surface 41 a and hardened. You may use the carbonizing method.

  Position detection means for tilt rotation of the tilt unit 40 is composed of a tilt optical sensor 363 and a tilt reflection scale 42. The details will be described below. The tilt position detection unit 360 is composed of an FPC 362 and a spacer 361 which are disposed on the arm portion 311 c of the pan chassis 311 opposite to the tilt drive unit 350. The tilt optical sensor 363 is mounted on the FPC 362. Then, a part of the tilt optical sensor 363 is disposed so as to intrude into the opening 311f formed in the arm 311c, and the tilt reflective scale 42 is opposed so as to be spaced at a predetermined distance. It is fixed. The FPC 362 is connected to the control substrate 220 via a wiring path formed inside the electronic device 100, and can output the detection result of the tilt optical sensor 363 to the CPU. Note that the FPC 362 is drawn by extracting only the necessary outer shape, and unnecessary portions are omitted in the description.

  An optical grating 42 a is formed around the tilt shaft portion 40 a in the tilt reflection scale 42 fixed to the tilt unit 40. The optical grating 42a has a pattern of light and dark arranged in the circumferential direction of the tilt shaft portion 40a at a constant cycle. As a base material used for the tilt reflective scale 42, a resin such as acrylic (PMMA) or polycarbonate (PC) is applied. Then, an optical grating 42a made of an aluminum film is formed as a reflective film on the surface of the base material. In addition, the base material of the reflective scale 42 for tilting is not limited to the above-mentioned base material, According to a use or the objective, it can select variously. For example, materials such as quartz glass, blue plate glass and silicon wafer may be used. The material of the reflective film is not limited to the aluminum film, and another reflective film such as a chromium film may be employed.

  The tilt optical sensor 363 mounted on the FPC 362 integrally packages a light emitting unit for emitting light to the tilt reflective scale 42 and a light receiving unit for receiving reflected light from the tilt reflective scale 42. It is a sensor. The light emitting unit is, for example, a light emitting diode, and the light receiving unit is, for example, a phototransistor. The light receiving unit receives the reflected light obtained by reflecting the light emitted by the light emitting unit on the light and dark pattern formed on the optical grating 42a. The tilt optical sensor 363 irradiates light to the optical grating 42 a arranged at a constant period from the light emitting portion to the tilt reflection scale 42, and the light reflected by the optical grating 42 a is provided to the tilt optical sensor 363. The light receiving portion receives light and converts it into an electric signal. At this time, the light reflected by the optical grating 42a forms an image of a reflection pattern, that is, a so-called reflectance distribution image. The light receiving unit photoelectrically converts this reflectance distribution image and outputs an electric signal of a sinusoidal waveform according to the light quantity distribution of the reflectance distribution image. When the tilt reflection scale 42 and the tilt optical sensor 363 move relative to each other, the reflectance distribution image formed on the light receiving portion from the optical grating 42 a changes. By reading a sinusoidal electric signal according to this change, it is possible to detect the amount of relative movement between the tilt reflective scale 42 and the tilt optical sensor 363, that is, the amount of rotation of the tilt unit 40.

  Next, with reference to FIG. 5, the configuration of an actuator for causing the pan unit 30 to rotate about the axis P in the pan direction and the configuration of a detection unit that detects the rotational position of the pan unit 30 will be described. FIG. 5 is an exploded perspective view of the pan drive unit 250 and shows a state in which the actuator for driving the pan unit 30 and the rotation detection unit of the pan unit 30 are incorporated into the base cover 210. In the base cover 210, the pan unit 30 excluding the exterior member configured in advance of the three parts of the right cover 320, the left cover 321, and the lens cover 322 of the transparent member is incorporated. The pan unit 30 is rotatably held in the pan direction about the axis P with respect to the base cover 210.

  A pan rotation plate 330 is fixed to the pan base 312 from the bottom side of the electronic device 100 by a screw. A pan reflection scale 331 is affixed and fixed to the pan rotation plate 330 via a double-sided tape (not shown). After the pan rotary plate 330 and the pan reflection scale 331 are incorporated into the base cover 210, the main chassis 240 is incorporated from the bottom side of the electronic device 100 and fixed by screws. In the main chassis 240, in addition to the screw holes for fixing to the base cover 210, openings 240a and 240b are formed. The opening 240 b has an opening shape in which a circular opening and a rectangular opening are adjacent to each other. The bundle of wires 51 extending from the tilt unit 40 is routed through the circular opening of the opening 240 b and connected to the control substrate 220.

  An actuator for driving the pan unit 30 and a sensor for detecting the rotation of the pan unit 30 are fixed to the main chassis 240. Specifically, the pan drive unit 250 is arranged to intrude inside the rectangular opening of the opening 240b. In addition, the pan position detection unit 260 is arranged to intrude into the inside of the opening 240a. Similar to the tilt drive unit 350 described above, the pan drive unit 250 is an actuator as a general ultrasonic motor that drives an object to be driven using ultrasonic vibration. For this reason, it is necessary to hold | maintain in the state which applied fixed pressure similarly to the tilt drive unit 350. FIG. The mechanism will be described below. The pan drive unit 250 includes a pan drive unit 251, a felt 252, a presser 253, a spring 254, and a case 255.

  FIG. 6 is an exploded perspective view of the pan drive unit 251. As shown in FIG. In FIG. 6, the vibrator 251 a is in pressure contact with the pan rotary plate 330. The piezoelectric element 251 b applies ultrasonic vibration to the vibrator 251 a. The FPC 251 c is a wiring material for bonding and fixing the piezoelectric element 251 b and applying a high frequency voltage to the piezoelectric element 251 b, and is a so-called flexible printed circuit. The base member 251 d holds these parts together. The pan drive unit 251 is a composite part combining these.

  The FPC 251 c constituting the pan drive unit 251 is directly connected to the control substrate 220 shown in FIG. 2 and receives a control signal from the driver IC to apply an arbitrary high frequency voltage to the piezoelectric element 251 b. The vibrator 251a has a plurality of contact points 251e. When a high frequency voltage is applied to the piezoelectric element 251b, vibration corresponding to the frequency is excited in the vibrator 251a. By controlling this vibration, the vibrator 251a and the pan rotary plate 330 can be relatively moved, and the pan unit 30 can be relatively moved. The FPC 251 c is drawn by extracting only the necessary outer shape, and unnecessary portions are omitted for explanation.

  Further, in the pan drive unit 250 shown in FIG. 5, the plurality of contact points 251 e are equally applied to the pan rotation plate 330 similarly to the tilt drive unit 350 shown in FIGS. 3 (a) and 3 (b). It is preferable to press. For this reason, as shown in FIG. 5, the spring 254 of the pan drive unit 250 holds the pan drive unit 251 via the felt 252 and the presser 253. The presser 253 is disposed inside the base member 251d of the pan drive unit 251, is slidable in a direction parallel to the axis P, and has a role of transmitting the pressure of the spring 254 as a wide range of surface pressure. The felt 252 is disposed between the presser 253 and the pan drive unit 251, and plays a role as a damping material that prevents the vibration generated by the vibrator 251a from being transmitted to the presser 253 and the spring 254 side.

  As shown in FIG. 5, the pan drive unit 251, the felt 252, the presser 253, and the spring 254 are disposed in an overlapping manner between the case 255 and the pan unit 30. Therefore, by fixing the case 255 to the main chassis 240 with a screw, the pressurized state can be maintained uniformly. Considering stable drive control and durability, high smoothness and wear resistance are required on the surface with which the contact point 251e of the vibrator 251a contacts. Therefore, in order to form a smooth flat surface, the surface processing such as lapping is applied to the friction sliding surface 330a which is a flat surface where the contact point 251e contacts the pan rotary plate 330. In addition, a stainless steel material is employed as the material of the pan rotary plate 330, and a high degree of flatness and wear resistance can be obtained by subjecting the friction sliding surface 330a to a hardening treatment such as a nitriding treatment. In addition, in order to obtain flatness and abrasion resistance, it is not limited to the above-mentioned processing method, for example, in order to obtain abrasion resistance, the corrosion which adds and hardens carbon on the surface of friction sliding face 330a is carried out. The charcoal method may be used.

  The pan position detection means of the pan unit 30 has a pan optical sensor 262 and a pan reflection scale 331. The details will be described below. The FPC 261 included in the pan position detection unit 260 is fixed to the main chassis 240 by a screw. At this time, the pan optical sensor 262 mounted on the FPC 261 is arranged such that a part of the pan optical sensor 262 intrudes into the opening 240 a. The FPC 261 is fixed so that the pan optical sensor 262 and the pan reflection scale 331 face each other at a predetermined distance. The FPC 261 is connected to the control substrate 220 via a wiring path formed inside the electronic device 100, and can output the detection result of the pan optical sensor 262 to the CPU. The FPC 261 is drawn by extracting only the necessary outer shape, and unnecessary portions are omitted in the description.

  An optical grating 331 a is formed around the pan shaft portion 312 a on the pan reflection scale 331 fixed to the pan unit 30. The optical grating 331 a has a pattern of light and dark arranged in the circumferential direction of the pan shaft portion 312 a with a constant period. The base material used for bread reflective scale 331 is a resin such as acrylic (PMMA) or polycarbonate (PC). Then, an optical grating 331 a made of an aluminum film is formed as a reflective film on the surface of the base material. In addition, the base material of the reflection scale 331 for bread is not limited to the above-mentioned base material, and can be variously selected according to the application and purpose. For example, materials such as quartz glass, blue plate glass and silicon wafer may be used. The material of the reflective film is not limited to the aluminum film, and a chromium film or the like may be employed.

  The pan optical sensor 262 mounted on the FPC 261 integrally packages a light emitting unit for irradiating light to the pan reflection scale 331 and a light receiving unit for receiving light reflected from the pan reflection scale 331. It is a sensor. The light emitting unit is, for example, a light emitting diode, and the light receiving unit is, for example, a phototransistor. The light receiving portions are arranged at a plurality of places in the range where the reflected light obtained by reflecting the light emitted from the light emitting portion to the light and dark pattern formed on the optical grating 331 a is incident. The pan optical sensor 262 irradiates light to the optical grating 331a arranged at a constant period from the light emitting portion to the pan reflection scale 331, and the light reflected by the optical grating 331a is provided to the pan optical sensor 262. The light receiving portion receives light and converts it into an electric signal. At this time, the light reflected by the optical grating 331 a forms an image of a reflection pattern, that is, a so-called reflectance distribution image. The light receiving unit photoelectrically converts the reflectance distribution image and outputs a sine wave electric signal according to the light amount distribution of the reflectance distribution image. When the pan reflection scale 331 and the pan optical sensor 262 move relative to each other, the reflectance distribution image formed on the light receiving portion from the optical grating 331 a changes. By reading a sinusoidal electric signal according to this change, the relative movement amount of the pan reflection scale 331 and the pan optical sensor 262, that is, the rotation amount of the pan unit 30 can be detected. The above is the details of the drive of the tilt unit 40 and the pan unit 30 of the electronic device 100.

  Next, referring to FIG. 7, an exterior structure for protecting the tilt unit 40 including the lens unit 50 will be described. FIG. 7 is a perspective view of the pan unit 30. As shown in FIG. FIG. 7 (a) is a front perspective view of the pan unit 30 including the left cover 321 and the right cover 320, which are exterior members, and the tilt unit 40 before the lens cover 322 is incorporated, and FIG. 7 (b) is a rear perspective view. Figure is shown. In FIG. 7A, screw holes 312a and 312b of the pan base 312 are provided to fix the left cover 321 and the right cover 320, which are exterior members, with screws. In FIG. 7B, screw holes 312c and 312d of the pan base 312 are provided for screwing the left cover 321 and the right cover 320, which are exterior parts, respectively. In FIG. 7A, the screw fastening portion 370a of the screw hole 312d is integrally formed with the blindfold part 370.

  8 and 9 are exploded perspective views of the pan unit 30, in which the left cover 321, the right cover 320, the lens cover 322, and the double-sided adhesive tape 323, which are exterior members, are incorporated into the pan unit 30 including the tilt unit 40. Is shown. In FIG. 8 in which FIGS. 8 and 9 are viewed from different points of view, the elastic member 325 is disposed between the pan base 312 and the right cover 321 and between the pan base 312 and the left cover 320. , It plays a role to prevent the water from entering into the inside from the joint part of the covers. The elastic member 325 is also disposed between the left cover 321 and the right cover 320. Details of the configuration for preventing water immersion from the mating portion of the respective covers by the elastic members 325 to the inside will be described later.

  Next, the order of assembly of each part will be described. As shown in FIG. 8, first, the elastic member 325 pans from the upper surface side of the tilt unit 40 to the pan unit 30 including the tilt unit 40 while expanding the ring-shaped portion (circular portion) 325 a of the elastic member 325. It assembles according to wall 312 f of base 312. Next, the right cover 320 is assembled from the XB direction of the tilt rotation axis T of the tilt unit 40. Next, the left cover 321 is assembled on the tilt rotation axis T of the tilt unit 40 from the XA direction opposite to the right cover 320. As described above, in the present embodiment, the right cover 320 is attached from a first direction (XA direction) parallel to the axis T, and the left cover 321 is a second direction (XB direction) opposite to the first direction. It is attached from.

  Next, the screws 380a, 380b, 380c and 380d are fastened from the lower side (bottom side) of the pan base 312 through the screw holes 312a, 312b, 312c and 312d of the pan base 312, respectively. As described above, the right cover 320 and the left cover 321 are respectively fixed from the bottom side of the lens unit 50 by the screws 380a, 380b, 380c, and 380d.

  Specifically, as shown in FIG. 9, the screw 380a is fastened to the screw fastening portion 320a of the right cover 320 via the screw hole 312a of the pan base 312 and the screw hole 321a of the left cover 321. The screw 380 b is fastened to the screw portion 320 b of the right cover 320 through the screw hole 312 b of the pan base 312. The screw 380 c is fastened to the screw portion 320 c of the right cover 320 through the screw hole 312 c of the pan base 312. The screw 380 d is fastened to the screw portion 370 a of the blindfold part 370 of FIG. 7B via the screw hole 312 d of the pan base 312 and the screw hole 321 d of the left cover 321. As described above, the left cover 321 and the right cover 320, which are exterior components for protecting the tilt unit 40, are fixed to the pan base 312 by the four screws.

  Next, the double-sided adhesive tape 323 is attached to the front groove portion 321 b of the left cover 321 and the front groove portion 320 d of the right cover 320. Thereafter, the lens cover 322 is attached from above to complete the assembly of the exterior member for protecting the tilt unit 40. The double-sided tape 323 may be a waterproof double-sided tape. The lens cover 322 needs to be made of a transparent member at a position covering an angle of view of at least the rotational movable range of the lens unit 50 that tilts and rotates around the axis T. However, when the double-sided adhesive tape 323 adheres to a transparent portion, the adhesive double-sided adhesive tape can be seen from the appearance side, and the appearance is not good in design. For this reason, it is possible to devise that the double-sided tape 323 can not be seen from the appearance by applying partial coating, printing, etc. only to the portion where the double-sided tape 323 is stuck. Further, partial coating, printing, and the like lead to an increase in the cost of parts, so the lens cover 322 may be formed by two-color molding. For example, the portion covering the lens unit 50 may be formed of a transparent member, and the other portion to which the double-sided adhesive tape 323 is attached may be formed of two materials such as a normal black resin.

  When the exterior members for protecting the tilt unit 40 shown in FIG. 7 are incorporated as an integral exterior part without being divided into left and right separately, they are incorporated from above, perpendicular to the tilt direction about the axis T It will be. In this case, the fastening screw position for fixing the integral exterior member needs to be disposed further outside the portion where the tilt drive unit 350 and the tilt position detection unit 360 are disposed. That is, the fastening screw position needs to provide a screw fixing portion outside the outermost periphery of the pan base 312. For this reason, an exterior cover will enlarge by the part of a screw fastening part. However, in the configuration of the present embodiment, the exterior cover is divided into the left cover 321 and the right cover 320, and assembled from both sides (XA direction, XB direction) in the tilt direction about the axis T. With such a configuration, the screws 380a, 380b, 380c, and 380d for fixing the left cover 321 and the right cover 320 are within the projection range from the top surface of the tilt drive unit 350, the tilt position detection unit 360, and the lens unit 50. It can be arranged. For this reason, it is not necessary to make the exterior cover protecting the tilt unit 40 extra large by the screw fastening amount, and it becomes possible to arrange the fastening screw. That is, the electronic device 100 can be miniaturized without increasing the size of the exterior member.

  Next, with reference to FIG. 10 to FIG. 13, the structure of the screw fastening portion for fixing the above-mentioned exterior members (left cover 321, right cover 320, lens cover 322) will be described. FIG. 10 is a bottom view (viewed from the bottom side) of the pan base 312 incorporating the exterior members (the left cover 321, the right cover 320, and the lens cover 322) for protecting the tilt unit 40. FIG. 11 is a cross-sectional view taken along the line A-A in FIG. FIG. 12 is a cross-sectional view taken along the line B-B in FIG. FIG. 13 is a cross-sectional view taken along the line R-R in FIG.

  The AA cross-sectional view of FIG. 11 is a cross-sectional view of the fixing portion of the screw (first screw) 380 d. The arrow YA direction in FIG. 11 is the fastening direction of the screw 380 d. The screw hole 321d of the left cover 321 is sandwiched between the screw portion 312d of the pan base 312 and the screw fastening portion 370a of the blind part 370, and is screwed by the screw 380d. Here, the contact surface 370aa of the screw fastening portion 370a of the blindfold member 370 and the contact surface 321da of the left cover 321 have an inclined surface shape that can contact each other. The inclined surface shape of the contact surface 321da of the left cover 321 is perpendicular to the left cover assembly direction XA, and becomes lower toward the outer peripheral direction from the rotation center (axis P) of the pan unit 30. The depth direction from the front of the sheet of FIG. 11 is the assembly direction XA of the left cover 321.

  The contact surface 321da of the left cover 321 is highest at the side of the axis P, which is the pan rotation center, and becomes lower as it is perpendicular to the assembly direction XA of the left cover 321 and toward the outer peripheral side. The abutment surface 370aa of the blind part 370 having the screw fastening portion 370a has a similar inclined surface shape to abut the abutment surface 321da of the left cover 321. As shown in FIG. 11, the left cover 321 having the inclined surface 321da when the screw 380d is tightened in the YA direction by forming the contact surfaces of the screw fastening portions in an inclined shape, as shown in FIG. Force in the direction of ZA is generated. The ZA direction is perpendicular to the assembly direction XA of the left cover 321, and is directed to an axis P which is a pan rotation center. For this reason, the left cover 321 always exerts a force toward the axis P, which is the pan rotation center, by the fastening of the screw 380d.

  In this manner, the screw 380 d abuts the contact surface 321 da of the left cover 321 and the contact surface 370 aa of the blindfold component 370 and the left cover 321 is held between the blind component 370 and the pan base 312. It is fixed to 321. Further, the contact surface 321 da of the left cover 321 and the contact surface 370 aa of the blind component 370 are inclined toward the bottom of the lens unit 50 from the axis P toward the outside of the electronic device 100.

  Next, with reference to FIG. 12, the structure of the screw (second screw) 380a will be described. The difference in configuration from the A-A cross-sectional view of FIG. 11 is that the screw fastening portion 320 a of the screw 380 a is integrally formed with the right cover 320. The screw portion 321 a of the left cover 321 is sandwiched and held by the screw hole portion 321 a of the pan base 321 and the screw fastening portion 320 a of the right cover 320. Therefore, it is possible to suppress the opening of the left cover 321 and the right cover 322 each other. The contact surface is inclined when the screw 380a is tightened in the YB direction by forming the contact surface 321aa of the screw fastening portion of the left cover 320 and the contact surface 320aa of the right cover 320 in an inclined shape. Therefore, a force in the ZB direction in FIG. 12 is generated. The ZB direction is perpendicular to the assembly direction of the left cover 321, and is directed to the axis P, which is the center of pan rotation. Therefore, the left cover 321 always generates a force toward the axis P, which is the pan rotation center, by the fastening of the screw 380a.

  As described above, the screw 380a abuts the contact surface 321aa of the left cover 321 and the contact surface 320aa of the screw fastening portion 320a of the right cover 320, and the left cover 321 is held between the screw fastening portion 320a and the pan base 312 It is fixed to the left cover 321 in the closed state. Further, the contact surface 321aa of the left cover 321 and the contact surface 320aa of the screw fastening portion 320a of the right cover 320 are inclined so as to approach the bottom surface side of the lens unit 50 from the axis P toward the outside of the electronic device 100. doing.

  Next, with reference to FIG. 13, the configuration of the screw (third screw) 380b will be described. The difference between the screw 380a in FIG. 11 and the screw 380d in FIG. 12 is that the screw fastening portion 320b of the screw 380b of the right cover 320 is in direct contact with the screw hole 312b of the pan base. That is, the contact surface 320ba of the screw 380b of the right cover 320 and the contact surface 312bb of the screw hole 312b of the pan base 312 are in contact with each other, and are inclined along each other. The sloped shape of the contact surface 320ba of the right cover 320 is perpendicular to the right cover assembly direction XB. Further, the contact surface 320ba has a shape that increases in the outer circumferential direction from the axis P, which is the pan rotation center. The depth direction from the front of the sheet of FIG. 13 is the assembly direction XB of the right cover 320. The contact surface 321ba of the right cover 320 is lowest at the side of the axis P which is the pan rotation center, and becomes higher as it is perpendicular to the assembly direction XB of the right cover 320 and toward the outer peripheral side.

  Thus, the screw 380 b is fixed to the right cover 320 in a state where the contact surface 320 ba of the right cover 320 and the contact surface 312 bb of the pan base 312 are in contact with each other. Further, the contact surface 320ba of the right cover 320 and the contact surface 312bb of the pan base 312 are respectively inclined away from the bottom surface side of the lens unit 50 from the axis P toward the outside of the electronic device 100.

  As shown in FIG. 13, when the screw 380 b is tightened in the YC direction by forming the contact surfaces of the screw fastening portions in an inclined shape, the right cover 320 having the inclined surface 320 ba is shown in FIG. A force is generated in the direction of ZB. The ZB direction is perpendicular to the assembly direction XB of the right cover 320, and is directed to an axis P which is a pan rotation center. For this reason, the right cover 320 is constantly urged toward the axis P, which is the pan rotation center, by the fastening of the screw 380b. The screw 380c can be configured the same as the screw 380b. If the screw 380c has the same configuration as the above-described screw 380b, the vector of force is directed in the ZA direction. Therefore, the right cover 320 is perpendicular to the XB direction which is the assembling direction, and a force is generated toward the axis P which is the pan rotation center. With such a configuration, for example, even when an impact is applied when the electronic device 100 is dropped, the left cover 321 and the right cover 320 can be easily opened in the direction opposite to the assembly direction (XA direction, XB direction). It can be suppressed.

  Next, the configuration for suppressing the opening of the upper surface portion of the left cover 321, the right cover 320, and the lens cover 322 will be described. As shown in detail G of FIG. 9, the lens cover 322 has two insertion parts 322a (first claw-shaped parts) and insertion parts (second claw-shaped parts) 322b in the upper surface part. The insertion portion 322a is inserted into the groove 321e of the left cover 321 shown in detail E in FIG. The insertion portion 322 b is inserted into the groove 320 e of the right cover 320 shown in detail F in FIG. 8. The side surface 322aa of the insertion portion 322a of the lens cover 322 and the side surface 322bb of the insertion portion 322b abut on the side surface 321f of the groove 321e of the left cover 321 and the side 320f of the groove 320e of the right cover 320, respectively. In this manner, the two insertion portions 322 a and 322 b of the lens cover 322 suppress the opening of the upper portions of the left cover 321 and the right cover 320.

  According to the present embodiment, by dividing the exterior member protecting the tilt unit 40 including the lens unit 50 into right and left, the projection area when the electronic device 100 is viewed from the top can be reduced. In addition, it is possible to suppress the opening of the exterior member that is likely to be generated by an impact due to a drop or the like of the electronic device 100, and it is possible to provide the compact electronic device 100 that is strong by the impact.
