Description

[Technical field]

[0001] The present invention relates to an electronic device having a swivel drive device, and more particularly to an electronic device that uses a wire for connection between a swivel drive unit and a fixed unit. [Background technology]

[0002] In recent years, multi-purpose cameras have become popular, allowing users to connect the installed camera to smartphones, PCs, tablet devices, etc. via wireless communication, allowing them to check the camera's footage from a distance.

[0003] By combining this type of camera with technologies such as image recognition and artificial intelligence, it is beginning to be applied to a variety of services.

[0004] For example, the applications range from supporting outdoor work, such as monitoring the progress and health of workers at construction sites, to installing devices in elderly care facilities to prevent people from forgetting to take their regular medications or taking the wrong medication.

[0005] One example of a housing configuration that can be applied to such a multi-purpose camera is a camera device in which the imaging direction can be set by horizontal rotation and vertical rotation (Patent Document 1).

[0006] In Patent Document 1, an imaging device and a vertical rotation mechanism are housed inside the horizontal rotation part, and further, a horizontal rotation mechanism, a horizontal rotation drive mechanism, and a vertical rotation drive mechanism are housed inside the fixed part.

[0007] The imaging signals of the imaging device housed inside the rotating part are transmitted to the inside of the fixed part and processed by the control board.

[0008] As the transmission means, for example, a flexible cable or the like as described in Patent Documents 2 and 3 is adopted, and is configured to be able to follow the movement of the movable part relative to the fixed part. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] JP 2002-369038 A [Patent Document 2] Japanese Patent Application Publication No. 8-178182 [Patent Document 3] JP 2014-212392 A Summary of the Invention [Problem to be solved by the invention]

[0010] However, in Patent Document 2, the cable is configured to be loosened without being restrained within the device.

[0011] Although such a configuration can reduce the stress on the cable caused by the movement of the movable part, a greater amount of slack is required to reduce the stress on the cable connection part, which is not suitable for miniaturization.

[0012] Moreover, in Patent Document 3, the cable is slackened in the radial direction, which results in a large projected area.

[0013] There was little consideration given to making the installation footprint small so that the imaging device could be installed anywhere, or to making the body size small and low-profile, so it was not necessarily easy to use as a multi-purpose camera.

[0014] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a slewing drive device which is compact and yet achieves a wiring structure capable of reducing stress on the wiring and wiring connections. [Means for solving the problem]

[0015] In order to achieve the above object, an electronic device of the present invention is an electronic device including a movable cylinder, a support cylinder that rotatably supports the movable cylinder around a panning rotation axis, a flexible wiring that connects a panning control board provided on the support cylinder, and a housing area that connects the movable cylinder and the support cylinder and houses the flexible wiring, the flexible wiring has a first fixed portion formed on the movable cylinder side and a second fixed portion formed on the support cylinder side, In the accommodation area, the first fixed portion is fixed to a first fixed portion of the movable cylinder, In the storage area, the second fixed portion is fixed by the second fixing portion of the support tube. 、 The second fixed portion is fixed so as to be aligned along the panning rotation axis of the movable barrel within the accommodation area of ​​the support barrel, and is fixed so as not to be aligned along the panning rotation axis of the movable barrel within the accommodation area of ​​the movable barrel, The second fixed portion is a bush member that is integrated with the flexible wiring so as to cover the outer periphery of the flexible wiring. It is characterized by: Effect of the Invention

[0016] According to the present invention, it is possible to provide a slewing drive device that is compact and yet realizes a wiring structure that can reduce stress on the wiring and wiring connections. [Brief description of the drawings]

[0018] Hereinafter, an image pickup device 100 as an electronic device according to an embodiment of the present invention will be described with reference to the accompanying drawings. Note that in the drawings, the same components are denoted by the same symbols.

[0019] The support cylinder 1 (fixed part) and the movable cylinder 2 (movable part) of the present invention are not limited to a cylindrical shape, and may be a rectangular shape (for example, a rectangular parallelepiped). EXAMPLES

[0020] Fig. 1 is a perspective view of an image pickup device 100 as an electronic device according to an embodiment of the present invention. Fig. 2(A) and Fig. 2(B) are exploded perspective views of the image pickup device 100 according to an embodiment of the present invention.

[0021] (Perspective view of the imaging device 100) The imaging device 100 is mainly composed of a movable section 2 and a fixed section 1. The movable section 2 is mainly composed of a top cover 10, a tilt unit 20, a pan unit base 30, and a pan unit rotating plate 40.

[0022] The fixed portion 1 mainly comprises a base cover 50, a chassis unit 60, a board assembly 70, and a bottom unit 80.

[0023] The movable part 2 is placed on top of the fixed part 1, and is held relative to the fixed part 1 so as to be capable of horizontal rotation (panning) around a rotation axis P as the center of rotation.

[0024] The top cover 10 has a transparent dome 11 molded from a transparent resin material such as acrylic resin.

[0025] The pan unit base 30 is disposed inside the top cover 10 and fixes and holds the top cover 10 with a number of screws.

[0026] The tilt unit 20 is disposed inside the top cover 10 and is held so as to be capable of vertical rotation (tilting) with a rotation axis T as the center of rotation with respect to the pan unit base 30.

[0027] The rotation axis P and the rotation axis T are perpendicular to each other, but they do not necessarily have to be perpendicular to each other.

[0028] A barrel unit 21 having an imaging optical system is disposed inside the tilt unit 20. The barrel unit 21 has an imaging element (not shown) inside.

[0029] This imaging element is composed of a photoelectric conversion element such as a CCD (Charge Coupled Device) sensor or a CMOS (Complementary MOS) sensor, a low-pass filter, and the like.

[0030] The low-pass filter prevents infrared rays from entering the lens, and prevents color moiré and other problems from occurring.

[0031] The imaging element is mounted on a printed circuit board (not shown) together with other electronic components inside the tilt unit 20, and a cable 22 is electrically connected to this printed circuit board.

[0032] The base 30 has a tilt drive source 32 that drives the driven body 20 .

[0033] The flexible wiring 31 connected to the drive source 32 is routed through the accommodation area S and electrically connected to the control board 70.

[0034] (bundle line 22) As shown in FIG. 3(A), the bundled wire 22 specifically includes a plurality of electric wires 22a each having a conductor core covered with an insulator, and connectors 22b, 22c connected to both ends of the electric wires 22a.

[0035] The electric wire 22a is bound with adhesive tape or the like (not shown) at positions close to the connectors 22b and 22c.

[0036] The electric wires 22a used in the bundle 22 may be a coaxial cable composed of an inner conductor, an insulator, an outer conductor, and a protective coating, if necessary.

[0037] The bundled wires 22 extend from the rear surface of the tilt unit 20 with one connector 22b electrically connected to a printed circuit board inside the tilt unit 20, and the other connector 22c electrically connected to the board assembly 70 on the fixed part 1 side.

[0038] The cable 22 further has a first fixed portion 22d and a second fixed portion 22e. The first fixed portion 22d is fixed to the rear surface of the tilt unit 20, and the second fixed portion 22e is fixed within the fixing portion 1.

[0039] In the imaging device 100 which is an embodiment of the present invention, the second fixed portion 22e of the cable 22 consists of a bush member 22f which is integrated to cover the outer periphery of the cable 22, and the cable 22 is fixed within the fixed portion 1 via this bush member 22f.

[0040] It is preferable that the bush member 22f is integrated with the bundle of wires 22 by means of pressure bonding, adhesion, insert molding, or the like.

[0041] The first fixed portion 22d of the cable 22 is made of an elastic member 22j such as a cushion, and the cable 22 is fixed to the rear surface of the tilt unit 20 via this elastic member 22j.

[0042] The bush member 22f is a cylindrical or doughnut-shaped mechanical part that is fitted onto a shaft or a cylindrical member to fill a gap or act as a buffer.

[0043] The region between the first fixed portion 22d and the second fixed portion 22e is a flexible excess portion 22g.

[0044] This surplus length portion 22g bends and twists within a surplus length accommodation area S, which will be described later, and thereby follows the panning drive and tilting drive of the movable part 2 relative to the fixed part 1.

[0045] The extra length 22g must be set to have at least a length necessary for the movable part 2 to follow the panning drive and tilting drive relative to the fixed part 1.

[0046] In order to ensure that the excess portion 22g has a length sufficient to provide sufficient flexibility within the limited excess length storage area S, it is preferable that the excess portion 22g be fixed at two points, the first fixed portion 22d and the second fixed portion 22e, as described above.

[0047] If a third fixed portion were added to the excess length portion 22g, the flexibility of the excess length portion 22g would be impaired, making it difficult for the excess length portion 22g to smoothly follow the panning drive and tilting drive.

[0048] However, when the surplus length portion 22g bends and twists, the surplus length portion 22g abuts to some extent against the inner walls that define the slack length accommodation area S, etc., which does not need to be considered as a problem.

[0049] Furthermore, as long as the length necessary for the movable part 2 to follow the panning drive and tilting drive relative to the fixed part 1 is secured, it is possible to increase the number of fixing points within the first fixed part 22d and the second fixed part 22e.

[0050] This makes it possible to more firmly fix the cable 22 without impeding the ability to follow the panning drive and tilting drive.

[0051] (Method of fixing the bundle of wires 22 to a fixing object via a bush member 22f) A method of fixing the cable bundle 22 to an object to be fixed via a bush member 22f will be described with reference to Figs. 3(B) and 3(C).

[0052] 3(B) and 3(C) are diagrams showing a method of fixing the bush member 22f by engaging it with an object to be fixed.

[0053] As shown in FIG. 3B, for example, an end of an opening 60a provided in a base chassis 601 described later is engaged with a recess 22i along a direction perpendicular to the opening 60a provided in a bush member 22f.

[0054] This allows the cable 22 to be securely fixed to the object to which it is fixed, and prevents the cable 22 from easily coming loose from the object.

[0055] The bushing member 22f may be press-fitted into the opening 60a, and in this case, it is preferable that the bushing member 22f is made of an elastic material such as a rubber material.

[0056] FIG. 3C shows a case where a relatively large connector is used as the connector 22c of the bundled wires 22.

[0057] In this case, as the connector 22c of the cable 22 becomes larger, the opening 60a of the base chassis 601 for inserting the connector 22c also becomes larger.

[0058] As a result, if one were to attempt to engage the recess 22i of the bush member 22f with the end of the opening 60a as in Figure 3(B), the bush member 22f would also need to be made larger, which would make it difficult to assemble when inserting the bundled wires 22 into the opening 60a.

[0059] Therefore, as shown in FIG. 3C, by fixing the bush member 22f of the cable 22 to the base chassis 601 via separate members such as holding members 6200 and 6300, the ease of assembly can be improved.

[0060] In addition to the above-described method of fixing the cable 22, the bush member 22f may be fixed to the object by screws or adhesive.

[0061] Moreover, the above-mentioned method of fixing the cable 22 can of course also be applied to the tilt unit 20 side.

[0062] In the tilt unit 20, a pair of shafts are formed on both side surfaces of the lens barrel unit .

[0063] In addition, the pan unit base 30 is provided with a pair of bearings capable of supporting the shaft of the tilt unit 20 around the rotation axis T.

[0064] By fitting these shaft portions and bearing portions together, the tilt unit 20 is held rotatably relative to the pan unit base 30.

[0065] Next, in the bread unit base 30, a hollow rotating shaft 30a extending in the thrust direction of the rotating shaft P is formed.

[0066] Further, the base cover 50 has a cylindrical portion 50a extending in the thrust direction of the rotation shaft P.

[0067] The hollow rotating shaft 30a and the cylindrical portion 50a are fitted together, so that the bread unit base 30 is configured to be rotatable with respect to the base cover 50.

[0068] In addition, the bread unit base 30 is assembled to the base cover 50 so as to be sandwiched between the bread unit base 30 and the bread unit rotating plate 40, and is held rotatably about the rotation axis P.

[0069] Furthermore, the pan unit base 30 has a flexible substrate 31 and a tilt drive unit 32 electrically connected to the flexible substrate 31 .

[0070] The flexible substrate 31 is electrically connected to the substrate assembly 70 inside the fixed portion 1 and is configured to follow the panning drive of the pan unit base 30 relative to the fixed portion 1 .

[0071] When an arbitrary drive signal is input from the substrate assembly 70, the tilt drive unit 32 outputs a drive force to perform tilting drive on the tilt unit 20.

[0072] The chassis unit 60 includes a base chassis 601 and a plurality of metal supports.

[0073] The base chassis 601 is made of a material such as aluminum or stainless steel (SUS), and is formed by pressing or drawing into a desired shape.

[0074] The multiple metal posts are made of materials such as SUS material or brass (BS material), and are joined and fixed to the base chassis 601.

[0075] Each support post is tapped so that it can be fastened with a screw. The chassis unit 60 is fixed to the base cover 50 with a screw (not shown).

[0076] The chassis unit 60 further includes a pan drive unit 610. The pan drive unit 610 includes a flexible substrate, one end of which is electrically connected to and fixed to the substrate assembly 70.

[0077] When an arbitrary drive signal is input from the substrate assembly 70, the pan drive unit 610 outputs a drive force to drive the pan unit rotating plate 40 in a panning manner.

[0078] The board assembly 70 abuts against metal posts of the chassis unit 60 and is fixed with screws.

[0079] Further, in the center of the base chassis 601 of the chassis unit 60, an opening 60a having a roughly circular shape is formed.

[0080] The cable 22 and the flexible board 31 are inserted into the opening 60a, so that the board assembly 70 can be accessed.

[0081] The bottom unit 80 is provided with a battery for operating the imaging device 100, operation buttons that can be pressed from the outside, and the like.

[0082] The bottom unit 80 is attached to the base cover 50 with screws (not shown) to complete the fixed portion 1, and the imaging device shown in FIG. 1 is completed.

[0083] (Explanation of the block diagram in Figure 7) FIG. 7 is a block diagram showing an example of the configuration of an image pickup apparatus 100 as an example of the image pickup apparatus of the present invention.

[0084] In FIG. 7, the system control unit 219 includes a processor (eg, a CPU, a GPU, a microprocessor, an MPU, etc.) and a memory (eg, a DRAM, an SRAM, etc.).

[0085] These execute various processes and control each block of the imaging device 100.

[0086] The non-volatile memory (EEPROM) 210 is an electrically erasable and recordable memory, and stores constants, programs, etc. for operating the control unit.

[0087] 7, a zoom unit 201 includes a zoom lens that changes magnification. A zoom drive control section 202 controls the drive of the zoom unit 201.

[0088] The focus unit 203 includes a lens for adjusting the focus. The focus drive control unit 204 controls the drive of the focus unit 203.

[0089] In the imaging unit 206, an imaging element such as a CCD or CMOS converts an optical image input through an optical system into an electrical signal, and outputs charge information according to the amount of incident light to an image processing unit 207 as analog image data.

[0090] An image processing unit 207 applies image processing such as distortion correction, white balance adjustment, and color interpolation processing to the digital image data output by A / D conversion, and outputs the digital image data after the processing.

[0091] The digital image data output from the image processing unit 207 is converted into a recording format such as JPEG format by the image recording unit 208 and sent to the memory 209 and video output unit 212 .

[0092] The lens barrel rotation drive section 205 drives the tilt drive unit 32 and the pan drive unit 610 to drive the lens barrel in the tilt direction and the pan direction.

[0093] The device shaking detection unit 222 includes, for example, an angular velocity meter (gyro sensor) that detects the angular velocity of the imaging device 100 in three axial directions, and an accelerometer (acceleration sensor) that detects the acceleration of the device in three axial directions.

[0094] The device vibration detection unit 222 calculates the rotation angle of the device, the amount of shift of the device, and the like based on the detected signal.

[0095] A microphone (audio input unit) 213 acquires an audio signal from the surroundings of the imaging device, and transmits the signal to an audio processing unit 214 after A / D conversion via an amplifier or the like.

[0096] The audio processing unit 214 performs audio processing such as optimization of the input digital audio signal.

[0097] Then, the audio signal processed by the audio processing unit 214 is sent to the memory 209 by the system control unit 219 .

[0098] The memory 209 temporarily stores the image signal and the audio signal obtained by the image processor 207 and the audio processor 214 .

[0099] The image processing unit 207 and the audio processing unit 214 read out the image signal and the audio signal temporarily stored in the memory 209, and encode the image signal and the audio signal, respectively, to generate a compressed image signal and a compressed audio signal.

[0100] The system control unit 219 transmits these compressed image signals and compressed audio signals to the recording and reproducing unit 216 .

[0101] A recording / playback unit 216 records onto a recording medium 217 the compressed image signal and compressed audio signal generated by the image processing unit 207 and audio processing unit 214, as well as other control data relating to image capture.

[0102] The recording medium 217 may be a recording medium 217 built into the imaging device 100 or a removable recording medium 217 .

[0103] The recording medium 217 can record various data such as compressed image signals, compressed audio signals, and audio signals generated by the imaging device 100, and a medium having a larger capacity than the non-volatile memory 210 is generally used.

[0104] For example, the recording medium 217 includes any type of recording medium 217, such as a hard disk, an optical disk, a magneto-optical disk, a CD-R, a DVD-R, a magnetic tape, a non-volatile semiconductor memory, a flash memory, and the like.

[0105] The recording / playback unit 216 reads (plays back) compressed image signals, compressed audio signals, audio signals, various data, and programs recorded on the recording medium 217 .

[0106] The system control unit 219 then transmits the read compressed image signal and compressed audio signal to the image processing unit 207 and audio processing unit 214 .

[0107] The image processing unit 207 and the audio processing unit 214 temporarily store the compressed image signal and the compressed audio signal in the memory 209, decode them in a predetermined procedure, and transmit the decoded signals to the video output unit 212 and the speaker (audio output unit) 215.

[0108] A speaker (audio output unit) 215 outputs a preset audio pattern during shooting or the like.

[0109] The LED control unit 211 controls a preset lighting and blinking pattern of the LEDs provided in the imaging device 100 during shooting or the like.

[0110] The video output unit 212 is, for example, a video output terminal, and transmits an image signal to display a video on a connected external display or the like.

[0111] The communication unit 218 performs communication between the image capture device 100 and an external device, and transmits and receives data such as audio signals, image signals, compressed audio signals, and compressed image signals.

[0112] The image capturing apparatus 100 also receives control signals related to image capturing, such as commands to start and stop image capturing, and pan / tilt and zoom drive, and drives the image capturing apparatus 100 according to instructions from an external device that can communicate with the image capturing apparatus 100 .

[0113] The communication unit 218 is, for example, a wireless communication module such as an infrared communication module, a Bluetooth communication module, a wireless LAN communication module, or a GPS receiver.

[0114] The power supply control unit 220 is made up of a battery detection circuit, a DC-DC converter, a switch circuit for switching between blocks to which electricity is applied, and the like, and detects whether a battery is attached, the type of battery, and the remaining battery level.

[0115] It also controls a DC-DC converter based on the detection result and instructions from the system control unit, and supplies the necessary voltage to each unit including the recording medium 217 for the necessary period.

[0116] The power supply unit 221 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, an AC adapter, or the like.

[0117] The power supply unit 221 and the power supply control unit 220 are connected via a camera side power supply connector and a power supply connector.

[0118] (Cross-sectional view of the main part of the wiring inside the imaging device 100) FIG. 4 is a cross-sectional view of a main part for explaining the configuration of wiring inside the imaging device 100 as an electronic device.

[0119] The imaging device 100 has a movable cylinder 2 and a support cylinder 1 that supports the movable cylinder 2 rotatably about a panning rotation axis P.

[0120] The imaging device 100 also includes a flexible wiring 22 that connects the panning control board 70 provided on the support barrel, and a housing area S that connects the movable barrel 2 and the support barrel 1 and houses the flexible wiring 22.

[0121] For ease of explanation, a cross-sectional view taken at the center of the first fixed portion 22d of the cable 22 in the vicinity of the tilt unit 20 is shown, and a cross-sectional view taken at the center of the rotation axis P in the vicinity of the fixed portion 1 is shown.

[0122] The cable 22 and the flexible board 31 are inserted through the inside of the hollow rotating shaft 30a extending in the thrust direction of the rotating axis P of the pan unit base 30 and through an opening 60a provided in the center of the base chassis 601, and are connected to the board assembly 70.

[0123] A first fixed portion 22d of the cable 22 is fixed to the rear surface of the tilt unit 20, and a second fixed portion 22e is fixed to a base chassis 601 in the fixed portion 1.

[0124] As a result, the surplus length portion 22g of the cable 22 is accommodated in the surplus length accommodating area S formed between the first fixed portion 22d and the second fixed portion 22e.

[0125] In the slack accommodating area S, the slack portion 22g of the cable 22 behaves so as to follow the panning and tilting movements of the movable part 2 relative to the fixed part 1.

[0126] During panning and tilting, the second fixed portion 22e is likely to be subjected to a load due to bending and twisting of the excess length portion 22g.

[0127] Therefore, by fixing the cable 22 via the bush member 22f integrated with the cable 22 as described above, the positional fluctuation of the fixed portion can be more reliably suppressed.

[0128] On the other hand, the first fixed portion 22d is dominated by a load caused by bending of the extra length portion 22g during tilting drive, and is not likely to be subjected to a load caused by twisting.

[0129] Therefore, a fixing method that is somewhat rougher than that for the second fixed portion 22e may be adopted.

[0130] In the imaging device 100 of this embodiment, an elastic member 22j such as a cushion is used for the first fixed portion 22d.

[0131] The upper cover 20a and the lower cover 20b constituting the tilt unit 20 sandwich an elastic member 22j to fix the cable 22 in place.

[0132] By employing an elastic member 22j for the first fixed portion 22d, not only can the positional fluctuation of the fixed portion be more reliably suppressed, but also the stress applied to the bundled wires 22 when clamped between the upper cover 20a and the lower cover 20b can be reduced.

[0133] On the other hand, the flexible substrate 31 is wound around the cable 22 multiple times within the slack receiving area S, and is connected to the substrate assembly 70.

[0134] One end 31a of the flexible substrate 31 is adhesively fixed to the pan unit base 30 with double-sided tape or the like (not shown), and the other end 31b is adhesively fixed to a vertical wall portion 620a provided on a first holding member 620 (described later) with double-sided tape or the like (not shown).

[0135] As a result, the wound portion 31c of the flexible substrate 31 is accommodated together with the surplus portion 22g of the cable 22 at a predetermined position within the surplus length accommodation area S.

[0136] This wound portion 31c, within the slack length accommodation area S, behaves in a loose or tight manner, thereby following the panning movement of the movable portion 2 relative to the fixed portion 1.

[0137] In this embodiment, the flexible wiring 22 has a first fixed portion 22d formed on the movable cylinder side and a second fixed portion 22e formed on the supporting cylinder side.

[0138] In the accommodation area S, the first fixed portion 22d is fixed to the first fixed portion of the movable barrel 2.

[0139] In the accommodation area S, the second fixed portion 22e is fixed by the second fixing portion of the support cylinder 1.

[0140] The second fixed portion 22e is fixed so as to be aligned along the panning rotation axis P of the movable barrel 2 within the storage area S of the support barrel 1, and is fixed so as not to be aligned along the panning rotation axis P of the movable barrel 2 within the storage area S of the movable barrel 2.

[0141] The second fixed portion 22e is a bush member 22f that is integrated with the flexible wiring 22 so as to cover the outer periphery of the flexible wiring 22.

[0142] The movable cylinder 2 has a base 30 supported on the support cylinder 1 so as to be rotatable around a panning rotation axis P, and a driven body 20 supported on the base 30 so as to be rotatable around a tilt rotation axis T extending in a direction different from the panning rotation axis P.

[0143] The flexible wiring 22 is led out from the driven body 20 .

[0144] The first fixed portion 22d is an elastic member 22j provided on the outer periphery of the flexible wiring 22.

[0145] The elastic member 22j is clamped in the driven body 20.

[0146] The first fixed portion 22d of the flexible wiring 22 is fixed to the driven body 20 at a position a predetermined distance L away from the panning rotation axis P of the base 30 in a direction parallel to the tilt rotation axis T of the driven body 20.

[0147] Within the accommodation area S of the movable cylinder 2, the flexible wiring 22 is loosened in the direction opposite to the direction in which it is drawn out from the driven body 20.

[0148] The support tube 1 has a first holding member 620 that holds the flexible wiring 31, and a second holding member 630 that, together with the first holding member 620, fixes the bush member 22f.

[0149] The bush member 22f has an engagement portion 22i provided in a direction perpendicular to the wiring direction of the flexible wiring 22 and a contact portion 22h formed at a position closer to the tip of the flexible wiring 22 than the engagement portion 22i.

[0150] Between the base 30 and the control board 70, the engagement portion 22i engages with an engagement portion 630a provided on the second holding member 630, and the abutment portion 22h abuts against an abutment portion 620b provided on the first holding member 620.

[0151] (Method of fixing the bundled wires 22 inside the fixing part 1 and method of fixing the flexible board 31) Next, a method for fixing the cable 22 inside the fixed portion 1 and a method for fixing the flexible board 31 will be specifically described with reference to FIG.

[0152] FIG. 5 is an exploded perspective view showing a detailed configuration of parts for fixing the cable 22 and the flexible board 31 inside the fixing part 1. As shown in FIG.

[0153] Directly below the slack accommodation area S, a first holding member 620 and a second holding member 630 are disposed.

[0154] The first holding member 620 has an upright wall portion 620a that protrudes along the rotation axis P toward the tilt unit 20 side, and the other end 31b of the flexible substrate 31 is adhesively fixed to this upright wall portion 620a.

[0155] The first holding member 620 is attached to the base chassis 601 so that the standing wall portion 620a is inserted into the slack length accommodation area S.

[0156] As a result, the wound portion 31c of the flexible substrate 31 is accommodated in the slack accommodating area S at a predetermined position.

[0157] The second holding member 630 has an engaging portion 630a along a direction substantially perpendicular to the rotation axis P, and a recess 22i of a bush member 22f integrated with the cable 22 so as to cover the outer periphery of the cable 22 engages with the engaging portion 630a.

[0158] Then, the second holding member 630 is positioned on the first holding member 620 while holding the cable 22 .

[0159] At the same time, the first holding member 620 is attached to the base chassis 601 with the abutment portion 22h of the bush member 22f abutting against the abutment portion 620b of the first holding member 620.

[0160] As a result, the cable 22 is held along the rotation axis P, and the slack portion 22g of the cable 22 is accommodated in the slack accommodation area S.

[0161] Furthermore, since the bush member 22f abuts against the first retaining member 620 while being engaged with the second retaining member 630, when the cable 22 twists within the slack storage area S, the cable 22 does not rotate inadvertently.

[0162] Since the cable 22 is fixed to the fixed portion 1 via the integrated bush member 22f in the above-described configuration, the cable 22 can be prevented from being easily pulled out.

[0163] In other words, when the surplus length portion 22g of the cable 22 bends and twists within the surplus length accommodation area S, it can follow the panning and tilting movements of the movable part 2 while always maintaining a constant length.

[0164] Furthermore, when the slack portion 22g of the cable 22 bends and twists within the slack accommodation area S, the position of the cable 22 does not fluctuate, so that a load is prevented from being applied to the connection portion to the board.

[0165] Furthermore, since the bush member 22f is positioned by the first holding member 620 that adhesively fixes and holds the flexible substrate 31, the positional relationship between the cable 22 and the flexible substrate 31 can be easily controlled.

[0166] That is, it becomes easy to set the positions of the cable 22 and the flexible board 31 so that they do not interfere with each other when they move, and this makes it possible to prevent problems such as disconnection caused by such interference.

[0167] Furthermore, when the movable part 2 is driven to pan, the cable 22 is only twisted about the rotation axis P and does not bend unnecessarily, so that the area occupied by the cable 22 within the imaging device 100 can be made as small as possible.

[0168] In other words, the slack length accommodation area S can be made smaller, and as a result, the imaging device 100 can be made more compact.

[0169] In addition, in the embodiment of the present invention, the cable 22 and the flexible board 31 are inserted through the extra length accommodation area S including the inside of the hollow rotation shaft 30a of the pan unit base 30 and connected to the board assembly .

[0170] This eliminates the need to pull out the cable 22 and the flexible board 31 from the side of the pan unit base 30.

[0171] As a result, it is possible to minimize the space occupied by the cable 22 and the flexible substrate 31 as they bend to follow the movable body 2.

[0172] That is, when viewed along the axis P, the imaging device 100 can be made smaller in size than when the cable 22 and the flexible board 31 are drawn out from the side of the pan unit base 30.

[0173] On the other hand, as the imaging device 100 is made more compact and the slack accommodation area S becomes smaller, the length of the slack portion 22g of the cable 22 that can be accommodated in the slack accommodation area S becomes shorter.

[0174] In an embodiment of the present invention, the excess length storage area S is efficiently used, and the excess length portion 22g of the cable 22 is configured to have a sufficient length to follow the panning and tilting drive of the movable part 2 relative to the fixed part 1.

[0175] (Top view of imaging device 100) Fig. 6 shows a top view of an image pickup apparatus 100 according to an embodiment of the present invention. For ease of explanation, the top cover 10 is not shown in Fig. 6, and the lens barrel unit 21 and the cable 22 are indicated by dashed lines.

[0176] A first fixed portion 22d of the cable 22 connected to the barrel unit 21 by a connector 22b is fixed and held on the rear surface of the tilt unit 20 at a position a predetermined distance L away from the rotation axis P in a direction parallel to the rotation axis T.

[0177] The slack portion 22g of the cable 22 is accommodated in the slack accommodation area S so as to slacken in the direction opposite to L in a direction parallel to the rotation axis T, and is fixed and held along the rotation axis P.

[0178] This allows the extra length 22g of the cable 22 to have a sufficient length required for the movable part 2 to follow the panning drive and tilting drive relative to the fixed part 1.

[0179] The support cylinder 1 (fixed part) and the movable cylinder 2 (movable part) of the present invention are not limited to a cylindrical shape, and may be a rectangular shape (for example, a rectangular parallelepiped).

[0180] Although the preferred embodiments and application examples of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and changes are possible within the scope of the gist of the present invention.
