Description

  The present invention relates to a mounting aid for mounting an imaging device at an inappropriate position, and an imaging device unit including the same.

  Generally, an imaging device such as a camera or a video recorder is provided with a mounting portion that can be mounted on a tripod or the like. The imaging device can be fixed to any place by attaching it to a tripod or the like through the attaching part (see, for example, Patent Document 1).

JP 2008-14979 A

  Here, when attached to a tripod or the like, the attachment portion of the imaging device is provided at the lower part of the imaging device so as to be an image in the direction normally viewed when reproducing a recorded image. It is fixed from the bottom while the imaging device is placed on a table or the like. Therefore, for example, when the image pickup apparatus is attached to the ceiling in order to record an image from the ceiling, an image in a state in which the attachment portion is located above and an image (photographed image) at the time of reproduction is normally viewed. Is rotated 180 degrees around the normal. Similarly, when an imaging device is attached to a side such as a side wall because there is no place to place a tripod or the positional relationship with the object to be imaged, the attachment portion is located horizontally and the photographed image is usually viewed The image of the state is rotated 90 degrees around the normal.

  Therefore, according to the present invention, an attachment assisting tool capable of attaching an imaging device so as to be able to take an image in a normally viewed state at an inappropriate position where the taken image rotates around the normal when the imaging device is attached at the attachment portion. And it aims at providing an imaging device unit provided with this.

(1) A supporting member formed to support at least the mounting portion of the imaging device provided with a mounting portion at a lower portion, and the mounting portion mounts the imaging device at the mounting portion. In the imaging device, the member attachment means for attaching the support member to the inappropriate position where it rotates and the image of the image that is usually viewed on the support member attached to the inappropriate position can be photographed. And a device fixing means capable of fixing the mounting portion.

  According to this, it is possible to capture an image in a direction normally viewed from the inappropriate position even in the imaging device provided with the mounting portion at the lower portion by attaching to the inappropriate position via the mounting aid. For example, an image pickup device having an attachment portion at the lower part is photographed from an image in a direction usually viewed in the state of being suspended from above, or an image in a direction usually observed in the state supported from the side Can be

  The improper portion may be a portion where the captured image is rotated around the normal of the captured image when the imaging device is directly attached by the attachment portion to the imaging device in which the attachment portion is provided at the lower portion. It is more preferable that the unsuitable portion be a portion where the photographed image rotates 90 degrees or more around the normal line when the mounting portion is directly attached. For example, a ceiling or a side wall, a frame that configures these, or the like may be used. Even if an imaging device is attached to a ceiling, a side wall, a frame that constitutes these, etc., it is possible to prevent an image rotated by 180 degrees and an image rotated by 90 degrees from being photographed.

  As an image to be usually viewed, when a display device capable of displaying a captured image is installed in a normal state and the captured image is displayed on the display device, the user is uncomfortable with the captured image displayed on the display device It may be configured to be viewed as an image that is hard to feel. An image that does not make the user feel uncomfortable may be an image that is not recognized as the displayed captured image being rotated up and down, and in particular, it may be an image in which the horizontal inclination is recognized to be equal to or less than a predetermined angle. . The predetermined angle may be, for example, 90 degrees.

  In particular, an excellent effect is exhibited in a configuration in which a photographed image is displayed on a rectangular display screen. In addition, in particular, when the photographed image is displayed on a horizontally long screen with an aspect ratio of 4: 3 or 16: 9, for example, the most excellent effect is exhibited. For example, when the display device is a television monitor, it is preferable that the displayed photographed image is an image which is less likely to be uncomfortable when the display device is usually installed on a television stand or the like without rotating the monitor.

  The mounting portion may be formed so as to be capable of capturing a horizontal image in a direction that is normally viewed when fixed to the horizontal mounting base from below. For example, it may be possible to capture a horizontal image in a direction that is normally viewed simply by attaching the mounting portion to a horizontally adjusted camera platform.

  The shape of the support member may be C-shaped, U-shaped, Z-shaped or annular. The ring shape may be, for example, an oval ring shape, but may be a circle. Furthermore, it is more preferable to have a support portion capable of supporting at least the attachment portion. For example, when the attachment portion is formed in a planar shape, the support portion may be formed in a flat shape, and when the attachment portion is formed in a curved surface, the support portion may be formed in a curved shape. That is, it is good to make it a surface contact with a support part and an attachment part. Also, for example, when the mounting portion is provided with a screw hole for fixation, the support portion may be able to support at least the screw hole. Further, the support member may be constituted by a plurality of members, for example, by connecting a plurality of members, but it is more preferable to constitute as a single member.

  As the member attachment means, it is preferable that the support member be attachable to an inappropriate place, and it is more preferable that the support member be firmly attachable to an inappropriate place so as not to be affected by forces such as vibration and inertial force. By firmly attaching the support member, the attachment state of the support member is maintained even when vibrations, sudden inertia forces and the like occur. Further, it is preferable that the member attachment portion be of the same type and the same standard as the device fixing means.

  As the device fixing means, the mounting portion may be fixed to the support member. For example, when the mounting portion is provided with a male screw, a screw hole may be used. When a screw hole of a predetermined size (for example, a 1/4 inch screw hole or the like) is formed in the mounting portion, a screw that can be screwed into the screw hole (1/4 inch screw in the above example) You should do it. Furthermore, in the case where the attachment hole is provided with a restriction hole for restricting the rotation of the imaging device, it is preferable to provide a projection that can be inserted into the restriction hole. By fixing the mounting portion to the support member in the state where the projection is inserted into the restriction hole, for example, even when the fixing by the device fixing means is loosened, the imaging device is not unnecessarily rotated.

(2) The support member is characterized in that the inside of the support member is formed to be rotatable about the normal line.

  According to this, by rotating the imaging device inside the support member attached to the inappropriate position, it is possible to easily adjust so that the captured image becomes a horizontal image in the direction in which the image is normally viewed. For example, even when the support member is attached to an inappropriate location or an inclined inappropriate location erected in the vertical direction, the captured image can be easily made to be a horizontal image in a direction usually viewed by rotating the imaging device. it can.

  The inside of the support member may be a portion surrounded by the support member. For example, the support member may be configured to surround at least a part of the imaging device. It is preferable that the inner surface side of the support member faces the outer surface side of the imaging device, and the distance between the inner surface of the facing support member and the outer surface of the imaging device does not have to be uniform. Good.

  In particular, the support member may be configured such that the user can insert the imaging device inside the support member. As the insertion direction, for example, when the support member is formed in a C shape or a U-shape, the width in which the side surface side in the surrounding direction (for example, the circumferential direction) of the support member is notched is larger than the diameter of the imaging device It is good to do. In this way, the imaging device can be easily inserted from the side surface notch of the support member (e.g., the space in the circumferential direction of the C-shape or the U-shape). Further, the width of the side surface of the support member in the surrounding direction (for example, the circumferential direction) is notched so that the width is smaller than the diameter of the imaging device to elastically deform the support member. It may be configured to be inserted.

  In the case where the imaging device is inserted from the direction perpendicular to the direction surrounding the insertion direction (for example, the circumferential direction) (for example, when the imaging device is inserted from the side that looks like a C character C), the insertion Preferably, the support device is configured such that the user can insert the imaging device in the direction.

  Note that the support member may be elastically deformed to be able to insert the imaging device, and it is more preferable to be able to insert the imaging device without being elastically deformed. In the case of insertion without being elastically deformed, it is more preferable to make the shape of the inner peripheral surface of the support member similar to the shape of the outer peripheral surface of the imaging device.

  The shape of the support member which can rotate inside the imaging device may be C-shaped or U-shaped, and may be annular. Further, as the size of the support member, it is preferable that the size of the rectangular box-like or cylindrical image-pickup apparatus can be rotated inside. That is, it is preferable that the shortest distance from the rotation axis of the imaging device to the inner surface of the support member be longer than the maximum distance from the rotation axis of the imaging device to the outer edge.

(3) The support member is characterized in that the end is not exposed to the outside.

  According to this, since the end portion is not exposed to the outside of the support member, even when the user unnecessarily touches the support member, it is possible to prevent an injury or the like of the user.

  As the outside, for example, when the support member is configured to surround at least a part of the imaging device, the support member may have a direction outside the surrounding direction. As a shape in which the end portion is not exposed to the outside, for example, a shape in which a C-shaped or U-shaped end portion is intruded into the inside may be used. More preferably, the support member has an endless annular shape. In addition, it is preferable to chamfer the end portion to make the end portion a curved surface.

(4) The support member is at least the central axis of the imaging device having the substantially planar mounting portion formed in a direction orthogonal to the central axis of the imaging device from the substantially cylindrical outer peripheral surface of the imaging device It is characterized in that it is formed in a ring shape having an inner circumferential surface of a radius equal to or greater than the distance from the outer edge of the mounting portion to the outer edge.

  According to this, it is possible to rotatably support the substantially cylindrical imaging device having the substantially planar attachment portion around the central axis.

  The ring shape may be a C shape that covers at least a semicircle or more of the outer peripheral surface of the imaging device. It is more preferable to form an annular shape that covers the entire outer peripheral surface of the imaging device. The annular shape may include an ellipse, but in particular, may be configured to include a true circle.

  The support member may extend from the tip of the imaging device in the imaging direction of the imaging device, and the extension portion may have a hood portion capable of restricting unnecessary light entering. In this case, the photographed image may be configured not to be caught by the hood portion. As a configuration in which the photographed image is not deceived by the hood portion, for example, it is preferable to extend from the tip of the imaging device in the imaging direction of the imaging device, but not to reach the range of the angle of view of the imaging device . By providing the hood portion, unnecessary light can be prevented from entering the imaging device. A lens filter or the like for protecting the lens of the imaging device may be attached to the hood portion. For example, a lens filter or the like for protecting the lens of the imaging device may be attached to the hood portion, and a threaded portion for filter attachment fitted with a screw of the filter may be provided.

  The support member may be extended in the direction opposite to the imaging direction of the imaging device to provide a rear end extension for protecting the rear end portion of the imaging device. By providing the rear end extending portion, when the SD card or the like is configured to be attachable to the rear end portion of the imaging device, it is possible to reduce easy removal of the SD card or the like. In this case, when the power cable or the like is connected to the rear end, it is preferable to provide a notch or the like for avoiding the connection position of the power cable.

(5) The support member has a flat portion capable of surface contact with the attachment portion.

  According to this, by bringing the mounting portion of the imaging device into surface contact with the flat portion of the support member, it is possible to prevent the imaging device from being unnecessarily rotated around the normal line of the captured image.

(6) The mounting portion has a screw hole in which a screw of a predetermined size can be screwed, and the flat portion of the support member has a through hole capable of penetrating the screw of the predetermined size. The device fixing means includes a screw capable of fixing the imaging device to the support member by being screwed into the screw hole through the through hole.

  According to this, it is possible to firmly fix the imaging device to the support member by fixing the imaging device in surface contact with the support member with a screw. The screw holes in the mounting portion may be screw holes for mounting on a general camera tripod. In addition, the device fixing means may be a screw equivalent to a screw for mounting on a tripod of a general camera. In this way, it is possible to easily remove the imaging device from the mounting aid and attach it to a tripod of a general camera, or remove it from the tripod and attach it to the attachment aid. . The screw holes in the mounting portion may be 1/4 inch screw holes, and the device fixing means may be 1/4 inch screws. In this case, the through hole may be formed so as to be able to penetrate the screw portion of the 1/4 inch screw and engage the head portion.

(7) The through hole is formed in an elongated hole shape extending around a central axis of the imaging device fixed to the support member.

  According to this, the imaging device can be fixed to the support member in a state in which the imaging device is rotated inside the support member. If a gap is generated between the rotated imaging device and the support member, an elastic member may be disposed between the imaging device and the support member.

(8) The apparatus is characterized in that the support member and the device fixing means are connected.

  According to this, since the device fixing means is connected to the support member, it is possible to prevent the device fixing means from being lost. For example, a connecting member rotatably connected to the support member may be provided. For example, in the case where the imaging device is fixed to the support member with a 1/4 inch screw, the provision of a connecting member that rotatably connects the 1/4 inch screw to the support member prevents the 1/4 inch screw from being eliminated.

(9) An imaging device unit comprising: a mounting aid; and an imaging device fixable to the mounting aid.

  According to this, it is possible to provide an imaging device that can be attached to an inappropriate point. The support member of the mounting aid and the imaging device may be provided with a rotation angle display unit capable of displaying the relative rotation angle of the imaging device with respect to the mounting aid.

  First, the initialized SD card 211 is attached to the SD slot unit 210 of the drive recorder 200. Next, as shown in FIG. 5A, the mounting aid 300 is mounted from the front of the drive recorder 200. Specifically, the drive recorder 200 is inserted into the ring member 301 of the attachment aid 300. At this time, the minimum length R3 from the center of gravity of the ring member 301 to the inner circumferential surface is formed to be longer than the maximum outer diameter R2 in the direction orthogonal to the center axis Z from the center axis Z of the drive recorder 200 Thus, the drive recorder 200 can be easily inserted into the ring member 301 and can be rotated about the central axis Z. In addition, when the power supply cable 308 provided on the rear end side is engaged with the ring member 301 when inserted from the front, the drive recorder 200 is prevented from being unnecessarily dropped from the ring member 301.

  Next, when the ring member 301 is inserted to the attachment portion 204 of the drive recorder 200, the drive recorder 200 is rotated about the central axis Z, and the flat portion 204a of the attachment portion 204 of the drive recorder 200 (1) Place it on the plane portion 301b. As a result, the flat surface portion 204 a of the mounting portion 204 makes surface contact with the first flat surface portion 301 b of the ring member 301, and the first flat surface portion 301 b can support the drive recorder 200. Also, by making the surface contact, unnecessary rotation of the drive recorder 200 at the time of installation is prevented.

  In this state, the 1/4 inch fixing bolt 303 is inserted into the 1/4 inch screw hole 205 provided in the plane portion 204a from below the first plane portion 301b (from outside the ring member 301) through the through hole 301d.

At this time, since the 1⁄4 inch fixing bolt 303 has a hexagonal head, the drive recorder 200 can be firmly fixed to the ring member 301. Further, since the ring member 301 is fixed in front of the microphone 207, it does not affect the collection of sound by the microphone 207 after attachment.

  When the ring member 301 is fixed to the drive recorder 200, the ring member 301 is fixed to the ceiling portion 401 of the forklift 400 with the lens cover 203 directed forward. Specifically, as shown in FIG. 5 (b), the second flat surface portion 301c of the ring member 301 to which the drive recorder 200 is fixed is brought close to the ceiling portion 401, and as shown in FIG. 6 (a), The 1⁄4 inch bolt 302 a passing through the through hole 402 formed in the ceiling portion 401 is screwed into the 1⁄4 inch nut 302 b joined to the 2 flat portion 301 c. At this time, the ring member 301 is fixed to the ceiling portion 401 while the lens cover 203 is directed forward and the direction around the vertical direction Y is adjusted. Thus, in the state where the drive recorder 200 is suspended from the ceiling portion 401, it is possible to capture an image in the same direction as the state that is normally viewed. In addition, the image of the state visually recognized normally means the image which becomes the same as the up-down direction of the direction in case a user visually recognizes from the ceiling part 401, for example.

  When the ring member 301 is fixed to the ceiling portion 401, the drive recorder 200 and the forklift 400 are connected with a commercially available strap via the strap holes 209 to prevent the drive recorder 200 from falling. Note that this work is optional. When the drive recorder 200 and the forklift 400 are connected, the power cable 308 is connected to the battery (not shown) of the forklift 400, thereby completing the installation of the drive recorder 200.

  As described above, according to the attachment assisting tool 300 according to the first embodiment, the drive recorder 200 provided with the attaching portion 204 in the lower part can capture an image in a state in which it is normally visually recognized. It can attach in the state suspended from the ceiling part 401. FIG.

Next, an imaging device unit 100A according to a second embodiment of the present invention will be described with reference to FIGS. 7 and 8 while using FIG. The imaging device unit 100A according to the second embodiment differs from the first embodiment in the attachment aid. Therefore, the difference from the first embodiment, that is, the attachment assisting tool will be mainly described, and the other configurations are denoted by the same reference numerals as the first embodiment, and the description thereof will be omitted. Moreover, in this embodiment, it demonstrates using the inclination flame | frame 410 provided in the ceiling part 401 of the forklift 400 as an unsuitable point.

  First, a schematic configuration of the imaging device unit 100A will be described with reference to FIG. 1 and FIG. Fig.7 (a) is a front view of the attachment aid 300 which concerns on 1st Embodiment, (b) is a side view, (c) is a bottom view.

  As shown in FIG. 1, the imaging device unit 100A includes a drive recorder 200, a mounting aid 300A for mounting the drive recorder 200 on the inclined frame 410 of the ceiling 401 of the forklift 400, the drive recorder 200 and the mounting aid 300. And a buffer member 310 disposed therebetween.

  As shown in FIGS. 7 (a) to 7 (c), the mounting aid 300A includes the ring member 304 for fixing the drive recorder 200 and the ring member 304 at an inappropriate position (in the present embodiment, the inclined frame 410 of the forklift 400). ) And a 1/4 inch fixing bolt 303 for fixing the ring member 304 to the drive recorder 200. As shown in FIG.

  As shown in FIG. 7A, the ring member 304 includes a curved surface portion 304 a whose inner peripheral surface is formed in a curved surface shape, and a second flat surface portion 301 c connected to the inclined frame 410 of the forklift 400. The drive recorder 200 is formed in an annular shape that can be inserted therein and in which the drive recorder 200 can be rotated. Specifically, in the ring member 304, the minimum length (length from the second flat portion 301c) R3 from the center of gravity to the inner peripheral surface of the ring member 304 is the central axis Z to the central axis Z of the drive recorder 200. It is formed to be longer than the maximum outer diameter R2 in the orthogonal direction (R2 <R3). By making the minimum length R3 from the center of gravity of the ring member 304 longer than the maximum outer diameter R2 from the center axis Z of the drive recorder 200, the drive recorder 200 can rotate around the center axis Z inside of it. .

  The axial length of the ring member 304 (the length in the direction in which the drive recorder 200 is inserted) is shorter than the length of the main body portion 201 of the drive recorder 200, and the axial length of the flat portion 204 a of the main body portion 201 is It is formed to be longer than the length. In the present embodiment, with the drive recorder 200 fixed to the ring member 304, the tip end side in the axial direction of the ring member 304 does not extend from the tip end of the drive recorder, and the rear end side in the axial direction extends above the microphone 207 It is formed to have a length that does not extend.

  The curved surface portion 304 a is formed in a curved surface shape in which the distance (radius) from the center of gravity to the inner circumferential surface is R4. The distance R4 from the center of gravity is longer than the distance to the second plane portion 301b which is the minimum length R3 from the center of gravity (R3 <R4), and does not prevent the rotation of the drive recorder 200 inserted into the ring member 301. It is supposed to be. Further, in the curved surface portion 304a, an elongated hole 304b which extends in the circumferential direction centering on the center of gravity and which can penetrate the bolt portion of the 1/4 inch fixing bolt 303 is formed, and within the range where the elongated hole 304b is formed. The drive recorder 200 can be fixed by the 1⁄4 inch fixing bolt 303 at any position in the circumferential direction. Further, by making the curved surface portion into a curved surface shape as in the first embodiment, unnecessary protrusion is eliminated, and the ring member can be miniaturized.

  The buffer member 310 is formed in a plate shape by an elastic member, and by interposing the drive recorder 200 and the ring member 304, transmission of vibration to the drive recorder 200 is alleviated. In addition, the loosening of the 1⁄4 inch fixing bolt 303 screwed into the 1⁄4 inch screw hole 205 is prevented. The buffer member may be any material that can be elastically deformed, such as synthetic rubber or sponge. In this embodiment, it is formed of a synthetic rubber.

  Further, the buffer member 310 is formed with an elongated hole having substantially the same shape as the elongated hole 304 b formed in the curved surface portion 304 a of the ring member 304, and even when the buffer member 310 is disposed, it is fixed at 1/4 inch. The bolt 303 is movable along the elongated hole 304 b.

  Next, a method of attaching the imaging device unit 100A according to the present embodiment will be described with reference to FIG. In this embodiment, the case where the imaging device unit 100A is attached to the through hole 411 formed in advance in the inclined frame 410 of the ceiling portion 401 of the forklift 400 will be described. FIG. 8 is a view showing a state in which the drive recorder 200 according to the second embodiment is attached to the tilt frame 410. As shown in FIG.

  First, the initialized SD card 211 is attached to the SD slot unit 210 of the drive recorder 200. Further, the buffer member 310 is disposed on the curved surface portion 304 a of the ring member 304.

  Next, the mounting aid 300A is attached from the front of the drive recorder 200. Specifically, the drive recorder 200 is inserted into the ring member 304 so that the buffer member 310 is sandwiched between the drive recorder 200 and the curved surface portion 304 a.

  Next, when the ring member 304 is inserted to the attachment portion 204 of the drive recorder 200, the 1/4 inch screw hole 205 provided in the flat surface portion 204a of the attachment portion 204 is inserted from outside the ring member 304 through the elongated hole 304b. Then, the 1/4 inch fixing bolt 303 is screwed to temporarily fix the drive recorder 200 to the ring member 304.

  When the ring member 304 is temporarily fixed to the drive recorder 200, the ring member 304 is then fixed to the inclined frame 410 of the ceiling portion 401 of the forklift 400 with the lens cover 203 directed forward. Specifically, first, the second flat surface portion 301c of the ring member 304 to which the drive recorder 200 is fixed is brought into proximity so as to be substantially parallel to the inclined frame 410, and 1/4 joined to the second flat surface portion 301c. The 1⁄4 inch bolt 302 a passing through the through hole 402 formed in the ceiling portion 401 is screwed into the inch nut 302 b.

  When the ring member 304 is fixed to the tilt frame 410, the 1/4 inch fixing bolt 303 is then loosened so that the temporarily fixed drive recorder 200 can be rotated. When the drive recorder 200 becomes rotatable, the drive recorder 200 is rotated so that the mounting portion 204 of the drive recorder 200 is positioned below the vertical direction Y as shown in FIG. When the mounting portion 204 of the drive recorder 200 is located below the vertical direction Y, the 1⁄4 inch fixing bolt 303 is tightened to fix the drive recorder 200 to the ring member 304. Thus, in the state where the drive recorder 200 is suspended from the ceiling portion 401, it is possible to capture an image in the same direction as the state that is normally viewed.

  When the ring member 304 is fixed to the inclined frame 410, the drive recorder 200 and the forklift 400 are connected with a commercially available strap via the strap hole 209 to prevent the drive recorder 200 from falling. Note that this work is optional. When the drive recorder 200 and the forklift 400 are connected, the power cable 308 is connected to the battery (not shown) of the forklift 400, thereby completing the installation of the drive recorder 200.

  As described above, according to the attachment assisting tool 300A according to the second embodiment, even when the drive recorder 200 provided with the attaching portion 204 at the lower portion is attached to the inclined frame 410 of the ceiling portion 401, the attaching portion 204. Can be fixed at a position where the drive recorder 200 is rotated so that the position of the drive recorder 200 is located below the vertical direction Y, and an image in a normally viewed state can be photographed.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to both above-mentioned embodiments (henceforth "this embodiment"). Further, the effects described in the present embodiment only list the most preferable effects resulting from the present invention, and the effects according to the present invention are not limited to those described in the present embodiment.

  For example, in the present embodiment, the drive recorder has been described as an example of the imaging apparatus, but the present invention is not limited to this. The imaging apparatus may be, for example, a substantially cylindrical camera or a video recorder used for home security, leisure, sports, etc. provided with a mounting portion at the lower part.

  Moreover, in this embodiment, although it demonstrated using the 1⁄4 inch fixing bolt 303 as an apparatus fixing means, this invention is not limited to this. The device fixing means only needs to be able to fix the drive recorder 200 to the ring members 301 and 304. For example, when the mounting portion is provided with a male screw, it may be a screw hole. When a screw hole of a predetermined size (for example, a 1/4 inch screw hole or the like) is formed in the mounting portion, a screw (1/4 inch screw) that can be screwed into the screw hole may be used. Furthermore, when the attachment hole is provided with a restriction hole for restricting the rotation of the imaging device, it is preferable to provide a protrusion that can be inserted into the restriction hole. By fixing the mounting portion to the support member in the state where the projection is inserted into the restriction hole, for example, even when the fixing by the device fixing means is loosened, the imaging device is not unnecessarily rotated.

  Further, in the present embodiment, although the 1/4 inch bolt 302a and the 1/4 inch nut 302b are used as the component attachment means, the present invention is not limited to this. The component attachment means should be able to attach the ring members 301 and 304 to an inappropriate location, and the ring members 301 and 304 can be attached firmly to an inappropriate location so as not to be affected by forces such as vibration and inertia. Then it is better. By firmly attaching the ring members 301 and 304, the attachment state of the ring members 301 and 304 is maintained even when vibrations, sudden inertia forces and the like occur. Further, it is preferable that the member attachment portion be of the same type and the same standard as the device fixing means.

  Also, for example, in the present embodiment, the ring members 301 and 304 are used as the support members, but the present invention is not limited to this. The supporting member may have at least a supporting portion for supporting the drive recorder 200 and a connecting portion for connecting to an inappropriate place. For example, C-shaped, U-shaped, Z-shaped and L-shaped members may be used. Further, it is more preferable that the support member be shaped such that a rectangular box-like or cylindrical imaging device can rotate around the normal line of the photographed image inside. The internal rotation makes it possible to adjust horizontally when installed at an inappropriate point. For example, when the support member is formed in a C shape, a U-shape, or an annular shape, the shortest distance from the rotation axis of the imaging device to the inner surface of the support member is greater than the maximum distance from the rotation axis of the imaging device to the outer edge It may be formed to be long.

  Furthermore, the support member may be shaped such that the end is not exposed to the outside. By doing this, for example, an injury or the like when the user touches the support member can be prevented. As a shape in which the end portion is not exposed to the outside, for example, a shape in which a C-shaped or U-shaped end portion is intruded into the inside may be used. More preferably, the support member has an endless annular shape. In addition, it is preferable to chamfer the end portion to make the end portion a curved surface.

  Further, in the present embodiment, the ring members 301 and 304 are formed to be able to support the mounting portion 204 of the drive recorder 200, but the present invention is not limited to this. For example, the ring member may be extended from the tip of the drive recorder 200 in the imaging direction Z1 of the drive recorder 200, and a hood may be provided inside the drive recorder 200 to prevent unnecessary light from entering. In this case, it is preferable to prevent the image from being broken by the hood portion. The lens filter may be attachable to the hood portion.

  Also, for example, the ring member is extended in the direction opposite to the imaging direction Z1 of the drive recorder 200 to prevent the SD card 211 from being unnecessarily pulled out from the SD slot 210 provided at the rear end of the drive recorder 200. A rear end extension may be provided. In this case, in order to avoid interference with the microphone 207 and the power supply cable 208, the portion may be cut away.

  Further, in the second embodiment, the drive recorder 200 is rotated inside the ring member 304 to horizontally fix the drive recorder 200. For example, the rotation angle of the drive recorder 200 and the ring member 304 It is preferable to provide a rotation amount display unit for displaying For example, when mounting a plurality of imaging device units on a plurality of forklifts of the same type, the rotational position of the drive recorder can be easily aligned simply by matching the rotation amounts displayed on the rotation amount display unit.

  In this embodiment, the power supply cable 308 provided on the rear end side when inserted from the front engages with the ring member 301, so that the drive recorder 200 is prevented from being unnecessarily dropped from the ring member 301. However, the drop prevention structure is not limited to this, and may be realized by another structure. For example, a protrusion may be provided on the outer peripheral portion closer to the center in the axial direction than the power cable, and the protrusion may be configured to abut on the ring member 301 to prevent the falling off. This also reduces the possibility of damaging the power cord.

  Further, in the present embodiment, the 1⁄4 inch nut 302b is disposed outside the second flat surface portion 301c, but may be disposed inside the second flat surface portion 301c (the side through which the drive recorder 200 is inserted). With this configuration, the second flat surface portion 301c can be in surface contact with the ceiling portion 401 and the inclined frame 410 of the forklift 400, and the ring members 301 and 304 can be firmly attached. In this case, it is preferable that (maximum outer diameter R2 + height of 1/4 inch nut 302b) <minimum length R3 from the center of gravity.

  Further, instead of arranging the 1/4 inch nut 302b, the through hole 301e of the second flat portion 301c may be screwed so that the threaded portion of the 1/4 inch bolt 302a can be screwed. With this configuration, the second flat surface portion 301c can be in surface contact with the ceiling portion 401 and the inclined frame 410 of the forklift 400, and the ring members 301 and 304 can be firmly attached. In addition, the number of parts can be reduced. In this case, it is preferable that the maximum outer diameter R2 <the minimum length R3 from the center of gravity.
