Description

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

  In general, an imaging device such as a camera or a video recorder is provided with an attachment portion that can be attached to a tripod or the like. The imaging apparatus can be fixed to an arbitrary place by attaching it to a tripod or the like via an attachment part (see, for example, Patent Document 1).

JP 2008-14979 A

  Here, the attachment part of the imaging device is provided at the lower part of the imaging device so that when attached to a tripod or the like, an image that is normally visually recognized when a recorded image is reproduced, the tripod cloud The imaging apparatus is fixed from below with the imaging apparatus mounted on a table or the like. Therefore, for example, when an image pickup device is to be attached to the ceiling in order to record an image from the ceiling, the attachment portion is positioned above, and an image (photographed image) when reproduced is normally viewed Rotate 180 degrees around the normal. Similarly, if there is no place to place a tripod or if the imaging device is to be attached to a side part such as a side wall due to the positional relationship with the subject to be photographed, the attachment part is positioned sideways and the photographed image is normally visually recognized. It becomes what rotated 90 degree | times around the normal line with respect to the image of a state.

  Therefore, the present invention provides an attachment auxiliary tool capable of attaching an imaging device so that an image that is normally visually recognized can be taken at an inappropriate location where the captured image rotates around the normal line when the imaging device is attached at the attachment portion. It is another object of the present invention to provide an image pickup apparatus unit including the same.

(1) A support member formed so as to be capable of supporting at least the mounting portion of the imaging device provided with a mounting portion at a lower portion, and when the imaging device is mounted by the mounting portion, the captured image is around the normal line of the captured image. The member of the imaging apparatus is configured so that a normally visible image can be taken on a member attaching means for attaching the support member to an inappropriate place that rotates, and the support member attached to the inappropriate place. And an apparatus fixing means capable of fixing the attachment portion.

  According to this, by attaching to an unsuitable place via an attachment auxiliary tool, the image of the direction normally visually recognized can be image | photographed from an unsuitable place also in the imaging device with which the attaching part was provided in the lower part. For example, an image capturing device having a mounting portion at the bottom is photographed in an orientation that is normally viewed while suspended from above, or an image that is normally viewed while being supported from the side. Can be.

  The improper location may be a location where the captured image rotates around the normal of the captured image when the imaging device is directly mounted at the mounting portion with respect to the imaging device having the mounting portion provided at the lower portion. The unsuitable part is more preferably a part where the photographed image is rotated 90 degrees or more around the normal line when the attachment part is directly attached. For example, it may be a ceiling, a side wall, and a frame constituting them. Even if the imaging device is attached to the ceiling, the side wall, and the frames constituting these, it is possible to prevent an image rotated by 180 degrees or an image rotated by 90 degrees from being captured.

  As a normally viewed image, 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 feels uncomfortable with the captured image displayed on the display device. It is good to comprise so that it may be visually recognized as an image which is hard to feel. The image that does not feel uncomfortable is particularly preferably an image that is not recognized that the displayed captured image is rotated up and down, and in particular, an image that is recognized as having a horizontal inclination of a predetermined angle or less. . For example, the predetermined angle may be 90 degrees.

  In particular, an excellent effect is exhibited in a configuration in which a captured image is displayed on a rectangular display screen. In particular, the most excellent effect is exhibited when a captured image is displayed on a horizontally long screen having a screen aspect ratio of 4: 3 or 16: 9, for example. For example, if the display device is a television monitor, the displayed captured image may be an image that does not feel uncomfortable in a state where it is normally installed on a television stand or the like without rotating the monitor.

  Note that when the mounting portion is fixed to the horizontal mounting base from below, it is preferable that the mounting portion is formed so as to be able to capture a horizontal image in a direction that is normally visually recognized. For example, it is preferable that a horizontal image in a normally visually recognized direction can be picked up simply by attaching a mounting portion to a horizontally adjusted pan head.

  The shape of the support member may be a C shape, a U shape, a Z shape, or an annular shape. As an annular shape, for example, an elliptical annular shape may be used, but a circle is more preferable. Further, it is more preferable to have a support portion that can support at least the attachment portion. For example, when the attachment portion is formed in a flat shape, the support portion may be flat, and when the attachment portion is formed in a curved shape, the support portion may be formed in a curved shape. That is, it is good to make it the structure which makes a support part and an attachment part surface-contact. In addition, for example, when a fixing screw hole is provided in the mounting portion, the support portion may support at least the screw hole. Moreover, although a support member may be comprised from several members, for example, connecting and comprising a some member, it is still more preferable to comprise as a single member.

  As the member attaching means, it is sufficient that the support member can be attached to an inappropriate location, and it is more preferable that the support member can be firmly attached to the inappropriate location so as to be hardly affected by a force such as vibration or inertia force. By firmly attaching the support member, the attachment state of the support member is maintained even when vibration, a sudden inertia force, or the like occurs. Further, the member mounting portion may be the same type and the same standard as the device fixing means.

  As the device fixing means, the attachment portion may be fixed to the support member. For example, when the attachment portion is provided with a male screw, the attachment portion may be a screw hole. In addition, when a screw hole of a predetermined size (for example, a 1/4 inch screw hole) is formed in the mounting portion, a screw that can be screwed into the screw hole (in the above example, a 1/4 inch screw) It is good to do. Furthermore, when a restriction hole for restricting the rotation of the imaging device is provided in the attachment portion, a protrusion that can be inserted into the restriction hole may be provided. By fixing the attachment portion to the support member in a state where the projection portion is inserted into the restriction hole, for example, even when the fixing by the device fixing means is loosened, the imaging device does not rotate unnecessarily.

(2) The support member is formed in a shape that allows the imaging device to rotate around the normal line.

  According to this, by rotating the imaging device inside the support member attached to an inappropriate place, the captured image can be easily adjusted so as to be a horizontal image in a direction that is normally visually recognized. For example, even when a support member is attached to an inappropriate place standing in the vertical direction or an inappropriate place inclined, the captured image can be easily converted into a horizontal image that is normally visually recognized 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. The inner surface side of the support member may be configured to face the outer surface side of the imaging device, and the distance between the inner surface of the opposing support member and the outer surface of the imaging device may not be uniform, but may be configured to be as uniform as possible. Good.

  In particular, the support member may be configured so that the user can insert the imaging device inside the support member. As an insertion direction, for example, when the support member is configured in a C shape or a U-shape, a configuration in which the width of notching the side surface in the surrounding direction (for example, the circumferential direction) of the support member is larger than the diameter of the imaging device Good. If it does in this way, an imaging device can be easily inserted from the side notch part (for example, space part in the peripheral direction of C character or U character) of a support member. Further, the width of notching the side surface in the surrounding direction (for example, the circumferential direction) of the support member is made smaller than the diameter of the imaging device, the support member is elastically deformed, and the imaging device is removed from the side notch portion of the support member. You may make it the structure inserted.

  Further, when the imaging device is inserted from a 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 of the C-shaped surface that appears to be C), the insertion is performed. The support member may be configured so that the user can insert the imaging device in the direction.

  Note that the imaging device may be configured to be insertable by elastically deforming the support member, and more preferably configured to be insertable without being elastically deformed. In the case of inserting without elastic deformation, the shape of the inner peripheral surface of the support member is more preferably similar to the shape of the outer peripheral surface of the imaging device.

  The shape of the support member that can rotate inside the imaging apparatus may be a C shape or a U shape, and more preferably an annular shape. In addition, the size of the support member may be a size that allows the rectangular box-shaped or cylindrical imaging device to rotate 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 is longer than the maximum distance from the rotation axis of the imaging device to the outer edge.

(3) The support member is formed in a shape whose 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 touches the support member unnecessarily, it is possible to prevent the user from being injured.

  As the outside, for example, when the support member is configured to surround at least a part of the imaging device, it is preferable that the direction be outside the surrounding direction. The shape in which the end portion is not exposed to the outside may be, for example, a shape in which the end portion formed in a C shape or a U shape enters the inside. More preferably, the support member is an endless ring. Further, the end portion may be chamfered and the end portion may be curved.

(4) The support member includes at least the central axis of the imaging apparatus having the substantially planar mounting portion formed in a direction orthogonal to the central axis of the imaging apparatus from a substantially cylindrical outer peripheral surface of the imaging apparatus. It is formed in the ring shape which has the internal peripheral surface of a radius more than the distance from the outer edge of the said attachment part.

  According to this, it is possible to support the substantially cylindrical imaging device having the substantially planar mounting portion so as to be rotatable around the central axis.

  The ring shape may be a C shape that covers at least a semicircle of the outer peripheral surface of the imaging device. It is even better to have an annular shape that covers the entire outer peripheral surface of the imaging device. The annular shape may include an ellipse, but it is particularly preferable to include a perfect circle.

  In addition, the support member may be configured to have a hood portion that extends from the distal end of the imaging device toward the imaging direction of the imaging device and that can restrict unnecessary light from entering the extended portion. In this case, it may be configured such that the captured image is not cut by the hood portion. As a configuration in which the captured image is not disposed by the hood portion, for example, the extension degree may be set so as to extend from the front end of the imaging device toward the imaging direction of the imaging device but does not 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 apparatus. More preferably, a lens filter or the like for protecting the lens of the imaging device can be attached to the hood portion. For example, a filter mounting threaded portion that fits with a filter screw may be provided in the hood portion so that a lens filter or the like for protecting the lens of the imaging device can be mounted.

  In addition, the support member may be extended in a direction opposite to the imaging direction of the imaging device to provide a rear end extension portion that protects the rear end portion of the imaging device. By providing the rear end extending portion, when the SD card or the like can be mounted on the rear end portion of the imaging apparatus, it is possible to reduce the fact that the SD card or the like is easily pulled out. In this case, when a power cable or the like is connected to the rear end, a notch or the like for avoiding the connection position of the power cable may be provided.

(5) The support member has a flat portion that can come into surface contact with the mounting portion.

  According to this, it is possible to prevent the image pickup device from rotating around the normal line of the picked-up image by bringing the attachment portion of the image pickup device into surface contact with the flat portion of the support member.

(6) The mounting portion has a screw hole into which a screw of a predetermined size can be screwed, and the flat portion of the support member has a through hole through which the screw of the predetermined size can pass. 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, the imaging device can be firmly fixed to the support member by fixing the imaging device in surface contact with the support member with the screw. The screw hole of the attachment portion may be a screw hole for attachment to a general camera tripod. The device fixing means may be a screw equivalent to a screw for mounting on a general camera tripod. In this way, it is possible to easily remove the imaging device from the main mounting aid and attach it to a general camera tripod, or remove it from the tripod and attach it to the main mounting aid. . The screw hole of the mounting portion may be a 1/4 inch screw hole, and the device fixing means may be a 1/4 inch screw. In this case, the through hole may be formed so as to be able to pass through the threaded portion of the 1/4 inch screw and engage the head portion.

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

  Accordingly, the imaging device can be fixed to the support member while being rotated inside the support member. When 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 support member and the device fixing means are connected to each other.

  According to this, since the apparatus fixing means is connected to the support member, it is possible to prevent the apparatus fixing means from being lost. For example, a connecting member that is rotatably connected to the support member may be provided. For example, when the imaging apparatus is fixed to the support member with a 1/4 inch screw, it is possible to prevent the 1/4 inch screw from being lost by providing a connecting member that rotatably connects the 1/4 inch screw to the support member.

(9) An imaging apparatus unit comprising an attachment assisting tool and an imaging device that can be fixed to the attachment assisting tool.

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

  According to the present invention, an attachment auxiliary tool capable of attaching an imaging device so that an image that is normally visually recognized can be taken at an inappropriate location where the captured image rotates around the normal line when the imaging device is attached at the attachment portion. And an imaging device unit provided with this can be provided.

It is formed in a planar shape. Further, the length in the horizontal direction X orthogonal to the axial direction of the first plane portion 301b is formed to be longer than the length in the plane direction orthogonal to the axial direction of the plane portion 204a of the drive recorder 200 (see FIG. 6 (b)), the entire surface of the flat portion 204a of the drive recorder 200 is formed so as to be in surface contact. By bringing the flat surface portion 204a of the drive recorder 200 into contact with the first flat surface portion 301b, the drive recorder 200 is prevented from rotating unnecessarily when the drive recorder 200 is fixed. In addition, the drive recorder 200 can be stabilized on the first plane portion 301b.

  The first flat surface portion 301b is formed with a through hole 301d that can penetrate a threaded portion of a 1/4 inch screw. In the present embodiment, the through hole 301d is formed at a substantially central portion of the first flat surface portion 301b. In addition, you may provide the projection part engageable with the control hole 206 in the 1st plane part 301b. In this case, (maximum outer diameter R2 + height of protrusion) <minimum length R3 from the center of gravity. By engaging the protrusion with the restriction hole 206, unnecessary rotation of the drive recorder 200 around the horizontal direction X is prevented. In the present embodiment, the length in the horizontal direction X of the first flat surface portion 301b is slightly longer than the length in the horizontal direction orthogonal to the axial direction of the flat surface portion 204a, so that the horizontal direction X of the drive recorder 200 is centered. This prevents unnecessary rotation.

  The second flat surface portion 301c is a portion located above the vertical direction Y when the ring member 301 is attached to the ceiling portion 401 of the forklift 400, and the upper surface is formed in a flat shape so that the 1/4 inch nut 302b can be joined.

The second flat surface portion 301c is formed with a through hole 301e that communicates with the 1/4 inch nut 302b and through which the screw portion of the 1/4 inch bolt 302a can be inserted. It is formed at a substantially central portion of the two plane portions 301c.

  The 1/4 inch nut 302b is joined to the upper surface of the second flat portion 301c so as to communicate with the through hole 301e. The 1/4 inch bolt 302a is formed to be able to be screwed to the 1/4 inch nut 302b through a through hole 402 provided in the ceiling portion 401 of the forklift 400. As described above, the ring member 301 is fixed to the ceiling portion 401 by screwing the 1/4 inch bolt 302a to the 1/4 inch nut 302b joined to the second plane portion so as to sandwich the ceiling portion 401. Is done. At that time, the ¼ inch bolt 302a is screwed into the ¼ inch nut 302b to achieve strong attachment. For example, even when vibration or a sudden inertia force is generated, the attachment state of the ring member 301 is maintained. Maintained.

  The 1/4 inch fixing bolt 303 is formed so as to be able to be screwed into a 1/4 inch screw hole 205 provided in the mounting portion 204 of the drive recorder 200. Specifically, the 1/4 inch fixing bolt 303 includes a screw portion having a diameter of about 6 mm and a length of about 4.5 mm, and a hexagonal head portion. The 1/4 inch fixing bolt is firmly attached to the first flat surface portion 301b of the drive recorder 200 by screwing the screw portion into the 1/4 inch screw hole 205 with a hexagonal head portion.

  Next, a method for attaching the imaging device unit 100 according to the present embodiment will be described with reference to FIGS. 5 and 6. In the present embodiment, the case where the imaging device unit 100 is attached to a through hole 402 formed in advance in the ceiling 401 of the forklift 400 will be described. FIG. 5A is a diagram showing a state in which the drive recorder 200 is fixed to the attachment assisting tool 300, and FIG. 5B is a diagram showing a state in which the attachment assisting tool 300 to which the drive recorder 200 is fixed is attached to the ceiling portion 401. It is. FIG. 6A is a side view showing a state where the drive recorder 200 according to the first embodiment is attached to the ceiling 401, and FIG. 6B is a front view.

  First, the initialized SD card 211 is inserted into the SD slot 210 of the drive recorder 200. Next, as shown in FIG. 5A, the mounting aid 300 is attached from the front of the drive recorder 200. Specifically, the drive recorder 200 is inserted into the ring member 301 of the mounting aid 300. At this time, the minimum length R3 from the center of gravity of the ring member 301 to the inner peripheral surface is formed to be longer than the maximum outer diameter R2 in the direction orthogonal to the central axis Z from the central axis Z of the drive recorder 200. Therefore, the drive recorder 200 can be easily inserted into the ring member 301 and can be rotated around the central axis Z. Further, when the power 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 unnecessarily falling off the ring member 301.

  Next, when the ring member 301 is inserted up to the mounting 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 mounting portion 204 of the drive recorder 200 is moved to the first portion of the ring member 301. It mounts on the 1 plane part 301b. As a result, the flat surface portion 204 a of the attachment portion 204 comes into 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. Further, the surface contact prevents unnecessary rotation of the drive recorder 200 during installation.

  In this state, the 1/4 inch fixing bolt 303 is inserted into the 1/4 inch screw hole 205 provided in the flat portion 204a from the bottom of the first flat portion 301b (from the outside of the ring member 301) through the through hole 301d. Screw together. As a result, the ring member 301 is sandwiched between the drive recorder 200 and the 1/4 inch fixing bolt 303, and the drive recorder 200 is fixed to the ring member 301. 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, the sound collection by the microphone 207 after the attachment is not affected.

  Once the ring member 301 is fixed to the drive recorder 200, the ring member 301 is then fixed to the ceiling 401 of the forklift 400 with the lens cover 203 facing forward. Specifically, as shown in FIG. 5B, 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. The 1/4 inch bolt 302a penetrating through the through hole 402 formed in the ceiling portion 401 is screwed into the 1/4 inch nut 302b joined to the two plane portions 301c. 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. As a result, 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 in a state that is normally visually recognized. Note that the image that is normally viewed refers to an image that is similar to the vertical direction of the direction when the user visually recognizes from the ceiling 401, for example.

  When the ring member 301 is fixed to the ceiling 401, the drive recorder 200 and the forklift 400 are connected with a commercially available strap through the strap hole 209 to prevent the drive recorder 200 from falling. This operation is optional. When the drive recorder 200 and the forklift 400 are connected, the power cable 308 is connected to a battery (not shown) of the forklift 400, whereby the installation of the drive recorder 200 is completed.

  As described above, according to the attachment assisting tool 300 according to the first embodiment, the drive recorder 200 provided with the attachment portion 204 at the lower portion can be used to capture an image that is normally visually recognized. It can be attached in a state of being suspended from the ceiling portion 401.

Second Embodiment
Next, an imaging apparatus unit 100A according to a second embodiment of the present invention will be described with reference to FIGS. The imaging apparatus unit 100A according to the second embodiment is different from the first embodiment in the attachment assisting tool. Therefore, here, the points that are different from the first embodiment, that is, the mounting aids will be mainly described, and the other components will be denoted by the same reference numerals as those in the first embodiment, and the description thereof will be omitted. Moreover, in this embodiment, it demonstrates using the inclination frame 410 provided in the ceiling part 401 of the forklift 400 as an unsuitable location.

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

  As shown in FIG. 1, the imaging apparatus unit 100A includes a drive recorder 200, an attachment aid 300A for attaching the drive recorder 200 to the inclined frame 410 of the ceiling 401 of the forklift 400, the drive recorder 200, and the attachment aid 300. And a buffer member 310 disposed between the two.

  As shown in FIGS. 7A to 7C, the attachment assisting tool 300A includes a ring member 304 for fixing the drive recorder 200, and the ring member 304 at an inappropriate place (in this embodiment, the inclined frame 410 of the forklift 400). 1/4 inch bolts 302a and 1/4 inch nuts 302b, and 1/4 inch fixing bolts 303 for fixing the ring member 304 to the drive recorder 200.

  As shown in FIG. 7A, the ring member 304 includes a curved surface portion 304a whose inner peripheral surface is formed in a curved shape, and a second flat surface portion 301c connected to the inclined frame 410 of the forklift 400. In addition, the drive recorder 200 can be inserted, and the drive recorder 200 is formed in an annular shape in which the drive recorder 200 can rotate. Specifically, the ring member 304 has a minimum length R3 from the center of gravity of the ring member 304 to the inner peripheral surface (a length from the second plane portion 301c) R3 to the center 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 be rotated around the center axis Z inside. .

  Further, 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 is smaller in the axial direction of the flat portion 204a of the main body portion 201. 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 to above the microphone 207. It is formed to have a length that does not extend.

  The curved surface portion 304a is formed in a curved surface shape having a distance (radius) from the center of gravity to the inner peripheral surface of R4. The distance R4 from the center of gravity is longer than the distance from the center of gravity to the second plane portion 301b, which is the minimum length R3 (R3 <R4), and does not hinder the rotation of the drive recorder 200 inserted into the ring member 301. It is like that. The curved surface portion 304a is formed with a long hole 304b extending in the circumferential direction around the center of gravity and penetrating the bolt portion of the 1/4 inch fixing bolt 303, and within the range where the long hole 304b is formed. The drive recorder 200 can be fixed by a 1/4 inch fixing bolt 303 at an arbitrary position in the circumferential direction. Further, similarly to the first embodiment, the curved surface portion has a curved surface shape, so that unnecessary protrusions are eliminated, and the ring member can be downsized.

  The buffer member 310 is formed in a plate shape by an elastic member, and the vibration transmission to the drive recorder 200 is mitigated by being sandwiched between the drive recorder 200 and the ring member 304. Further, the 1/4 inch fixing bolt 303 screwed into the 1/4 inch screw hole 205 is prevented from loosening. The buffer member may be any elastically deformable material such as synthetic rubber or sponge. In this embodiment, it is formed of synthetic rubber.

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

  Next, a method for attaching the imaging device unit 100A according to the present embodiment will be described with reference to FIG. In the present embodiment, the case where the imaging device unit 100A is attached to a through-hole 411 formed in advance on 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 inclined frame 410.

  First, the initialized SD card 211 is inserted into the SD slot 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 304a.

  Next, when the ring member 304 is inserted to the mounting portion 204 of the drive recorder 200, the 1/4 inch screw hole 205 provided in the flat portion 204a of the mounting portion 204 is inserted into the 1/4 inch screw hole 205 from the outside of 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.

  Once 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 facing forward. Specifically, first, the second flat surface portion 301c of the ring member 304 to which the drive recorder 200 is fixed is brought close to the inclined frame 410 so as to be joined to the second flat surface portion 301c. A 1/4 inch bolt 302a penetrating through a through hole 402 formed in the ceiling portion 401 is screwed into the inch nut 302b.

  When the ring member 304 is fixed to the inclined 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 positioned 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. As a result, 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 in a state that is normally visually recognized.

  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 through the strap hole 209 to prevent the drive recorder 200 from falling. This operation is optional. When the drive recorder 200 and the forklift 400 are connected, the power cable 308 is connected to a battery (not shown) of the forklift 400, whereby the installation of the drive recorder 200 is completed.

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

  As mentioned above, although embodiment of this invention was described, this invention is not limited to both embodiment mentioned above (henceforth "this embodiment"). In addition, the effects described in the present embodiment are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the present embodiment.

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

  Moreover, in this embodiment, although 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, in the case where a male screw is provided in the mounting portion, the device fixing means may be a screw hole. Further, when a screw hole of a predetermined size (for example, a 1/4 inch screw hole or the like) is formed in the attachment portion, a screw (1/4 inch screw) that can be screwed into the screw hole may be used. Furthermore, when a restriction hole for restricting the rotation of the imaging device is provided in the attachment portion, a protrusion that can be inserted into the restriction hole may be provided. By fixing the attachment portion to the support member in a state where the projection portion is inserted into the restriction hole, for example, even when the fixing by the device fixing means is loosened, the imaging device does not rotate unnecessarily.

  In the present embodiment, the 1/4 inch bolt 302a and the 1/4 inch nut 302b are used as the component mounting means, but the present invention is not limited to this. The component attaching means only needs to be able to attach the ring members 301 and 304 to an inappropriate location, and can firmly attach the ring members 301 and 304 to an inappropriate location so as not to be easily affected by a force such as vibration or inertia force. Even better. By firmly attaching the ring members 301 and 304, the attachment state of the ring members 301 and 304 is maintained even when vibration, a sudden inertia force, or the like occurs. Further, the member mounting portion may be the same type and the same standard as the device fixing means.

  For example, in the present embodiment, the annular ring members 301 and 304 are used as the support members, but the present invention is not limited to this. The support member only needs to have at least a support portion that supports the drive recorder 200 and a connection portion that is connected to an inappropriate location. For example, C-shaped, U-shaped, Z-shaped and L-shaped members may be used. Further, it is more preferable that the support member has a rectangular box-like or columnar imaging device that can rotate around the normal line of the captured image. By making it possible to rotate inside, it can be adjusted horizontally when attached to an inappropriate place. 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 larger than the maximum distance from the rotation axis of the imaging device to the outer edge. It is good to form so that it may become long.

  Further, the support member may have a shape in which the end portion is not exposed to the outside. By doing in this way, the injury etc. when a user touches a supporting member can be prevented, for example. The shape in which the end portion is not exposed to the outside may be, for example, a shape in which the end portion formed in a C shape or a U shape enters the inside. More preferably, the support member is an endless ring. Further, the end portion may be chamfered and the end portion may be curved.

  In the present embodiment, the ring members 301 and 304 are formed so as 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, a 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 portion that prevents unnecessary light from entering the drive recorder 200 may be provided. In this case, it is preferable that the image is not drawn by the hood portion. A lens filter may be attached to the hood.

  Further, for example, the ring member is extended in the direction opposite to the imaging direction Z1 of the drive recorder 200, and the SD card 211 is prevented from being unnecessarily removed from the SD slot portion 210 provided at the rear end portion 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 cable 208, the part is preferably cut out.

  In the second embodiment, the drive recorder 200 is rotated inside the ring member 304 and the drive recorder 200 is fixed horizontally. For example, the rotation angle of the drive recorder is set between 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 positions of the drive recorders can be easily aligned only by matching the rotation amounts displayed on the rotation amount display unit.

  In the present embodiment, when the power 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 detached from the ring member 301. However, the drop-off 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 contact the ring member 301 to prevent falling off. In this way, the possibility of damaging the power cord can be reduced.

  In the present embodiment, the ¼ 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). By comprising in this way, the 2nd plane part 301c can be surface-contacted with the ceiling part 401 and the inclination frame 410 of the forklift 400, and the ring members 301 and 304 can be attached firmly. In this case, it is preferable that (the maximum outer diameter R2 + 1/4 inch nut 302b height) <the minimum length R3 from the center of gravity.

  Instead of arranging the 1/4 inch nut 302b, a screw may be formed in the through hole 301e of the second flat portion 301c so that the screw portion of the 1/4 inch bolt 302a can be screwed. By comprising in this way, the 2nd plane part 301c can be surface-contacted with the ceiling part 401 and the inclination frame 410 of the forklift 400, and the ring members 301 and 304 can be attached firmly. 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.
