  2. Description of the Related Art Conventionally, there has been known an imaging apparatus capable of changing the shooting direction of a camera attached to an arbitrary attachment location by changing the orientation of the camera lens with respect to an attachment member, such as a security camera or a drive recorder. For example, in a drive recorder, a drive recorder main body having a cylindrical portion (hereinafter referred to as “Drareco main body”) is attached to a vehicle windshield with the cylindrical portion being horizontal, and the horizontal direction is the vertical axis. A configuration in which the photographing direction can be changed by rotating is known (for example, see Patent Document 1).

JP 2010-105530 A

  Here, the drive recorder described above is generally affixed to a vehicle windshield and used to photograph the front of the vehicle. However, the drive recorder can be affixed to a vehicle rear glass and used as a rear camera for photographing the rear of the vehicle. Thought.

  However, for example, in the case of a one-box type vehicle in which the rear glass is erected almost vertically, if the camera is attached to the rear glass after the camera is attached to the rear glass by the mounting member, one of the mounting members attached to the rear glass is used. May appear in the image captured by the camera. In particular, when a wide-angle lens is used, the mounting member is likely to be reflected, which may affect the reproduced image. Moreover, when attaching a camera to a rear glass, it discovered that there existed various subjects, such as it being desirable to make it as small as possible and to make it inconspicuous.

  Accordingly, an object of the present invention is to provide, for example, a small imaging device that can be attached to a desired attachment location in a state in which the reflection of the attachment member is prevented, and an imaging system including the same.

(1) An imaging apparatus comprising a camera and an attachment member for attaching the camera to a desired attachment location, wherein the attachment member is substantially the same as a support means for supporting the camera, and a photographing direction of the camera. An image pickup apparatus comprising: an attachment plate configured to be attachable to the desired attachment location on one side orthogonal to each other and extending in a direction away from the lens of the camera.

  According to this, when the camera is attached to the desired attachment location so that the desired attachment location and the lens face each other, it is attached to the image captured by the camera while increasing the attachment area of the attachment plate to the desired attachment location. The lens and the mounting plate can be brought close to each other so that the plate is not reflected. That is, it is possible to reduce the size of the camera while preventing the attachment member from being reflected.

  For example, if the mounting plate is made small in order to eliminate reflections, the mounting plate may be easily peeled off or unstable when it is attached to a desired mounting location with double-sided tape. By extending in the direction away from each other, the mounting area of the mounting plate can be increased while suppressing the influence on the reflection. That is, it is possible to make the mounting plate difficult to peel off from a desired mounting location and to stabilize the mounting plate with respect to the desired mounting location.

  The desired mounting location may be a desired location where the camera can be mounted, for example, a desired location on the rear glass of the vehicle or a desired location on the window glass of the building.

  The support means may be configured to support the camera so that the direction of the lens of the camera can be changed, and more preferably configured to support the camera rotatably. In particular, it is preferable to support the camera so that the camera can rotate 360 degrees. For example, when the camera has a substantially cylindrical shape, the support means may be ring-shaped.

  In the case where the support means supports the camera in a rotatable manner, the camera may be configured to support the camera so that the camera rotates smoothly, and the camera may be configured to support the camera so as to rotate stepwise. For example, it is good to set it as the structure supported so that a camera may rotate 5 degree | times with respect to a rotation support member.

  In the case where the support means is configured to rotatably support the camera, a fixing means for fixing the support means at an arbitrary rotational position may be provided. For example, the fixing means may be configured to rotate when a predetermined or higher rotational torque is applied, and to hold the rotational position when a rotational torque less than a predetermined value is applied. For example, the rotation torque that is greater than or equal to a predetermined value may be a rotation torque caused by the user rotating the camera, and the rotation torque that is less than the predetermined value may be a rotation torque that acts due to vibration of an attachment location (for example, a vehicle). . Further, it is more preferable that the support means is sandwiched and fixed between the camera and the fixing means. In this case, the fixing means may be a fixing member that is screwed into the camera and holds the supporting means.

  The mounting plate may be configured to extend from the support means in a direction away from the lens, and more preferably from the end of the support means. For example, the mounting plate may be configured to be directly or indirectly connected to the support means.

  The shape of the mounting plate is not particularly limited, but may be a rectangular shape, and at least the length in the direction away from the lens may be longer than the length in the direction substantially perpendicular to the direction away from the lens. For example, it is good to make it the substantially rectangular shape which made the direction away from a lens the longitudinal direction.

  The direction away from the lens may be a radial direction with respect to the lens, and in this case, it may be a substantially fan shape. Further, the direction away from the lens may be configured to extend in one of the radial directions, and in this case, it may be substantially rectangular. For example, when the camera is substantially cylindrical and a lens is disposed on the outer peripheral surface, the direction may be along the central axis of the camera.

  The length of the mounting plate in the direction away from the lens (for example, the length in the longitudinal direction) is such that, for example, when the camera is attached to any mounting location with double-sided tape, the camera is not unnecessarily peeled off from the mounting location. What is necessary is just to have an affixing area where the double-sided tape can exert force. In this case, the mounting surface of the mounting plate may be substantially flat. By making the mounting surface substantially flat, for example, the mounting plate can be easily attached to any mounting location with double-sided tape. For example, the length away from the lens may be configured so as not to protrude from the end of the camera as much as possible.

  The camera may be configured to have a substantially cylindrical portion in part, and more preferably has a substantially cylindrical shape as a whole. By making the entire camera into a substantially cylindrical shape, changes in the shape of the camera when the camera is rotated can be reduced. For example, it can be used without discomfort even if it is rotated after being attached to any mounting location Can do. Further, by making the entire camera into a substantially cylindrical shape, for example, the camera can be easily picked, and the camera can be easily rotated when changing the shooting direction. Furthermore, by making the entire camera into a substantially cylindrical shape, the appearance of the camera can be shown cute.

  The camera may be configured to use a wide-angle lens, for example, a wide-angle lens having a diagonal angle of 150 to 170 degrees. For example, when attached to the windshield of a car, it is possible to take a picture of the range up to the extent where a pillow appears at a diagonal of 160 degrees, and it is possible to take pictures of the situation of a vehicle traveling in the right and left lanes when stopping at an intersection. . Further, for example, in a work vehicle such as a forklift, it is possible to take a picture including a road on the outer side of the work vehicle such as a forklift. For this reason, it is possible to confirm from a recorded image that a work vehicle such as a forklift has stepped on something, dropped a load, or has a step.

(2) The mounting plate has notches at both ends on the lens side in a direction substantially orthogonal to the separating direction when positioned on the one side of the camera.

  According to this, the lens and the attachment member can be brought closer to each other than in the case where the notch portion is not provided. For example, the mounting plate can be disposed in the immediate vicinity of the lens. That is, the camera unit can be further downsized. In particular, even when a wide-angle lens is used, the lens and the mounting plate can be brought close to each other without cutting the both ends on the lens side so that the mounting plate does not appear in the image captured by the camera.

  The shape of the notch may be a shape and / or a range based on the range of the image captured by the camera, and in particular, a shape and / or a distortion taking into account the distortion of the shooting range of the camera caused by the configuration of the optical system or the like. Or the range.

  For example, the shape of the cutout portion may be a rectangular shape, and the cutout portion can be formed more easily and reliably by cutting out into a rectangular shape.

(3) The attachment member includes band attachment means capable of attaching a fixing band for fixing the attachment member attached to the desired attachment location to the desired attachment location.

  According to this, it can fix with a fixed band so that the attachment member attached to the desired attachment location may not drop from a desired attachment location. For example, even when the attachment member is attached to the outside of the vehicle with a double-sided tape, the attachment member can be prevented from falling off from a desired attachment location even when the adhesive strength of the double-sided tape is reduced.

  For example, the fixing band may be configured to be wound around and fixed to a frame of a work vehicle such as a forklift, and more preferably to have a one-way mechanism that can be tightened only in one direction and does not loosen once tightened. The shape of the fixed band is preferably a band shape. As the fixed band, for example, a binding band may be used.

  The band attachment means may be provided on the surface opposite to the attachment surface of the attachment plate, or may be provided on the support means.

  Moreover, it is good also as a structure provided in the connection part between an attachment board and a support means. In the case where the band attachment means is provided at the connection portion between the attachment plate and the support means, it is preferable to provide the connection portion so that the strength of the connection portion does not decrease. For example, in the case where an insertion hole through which the fixing band can be inserted is provided in the connection portion, the connection portion may be configured to be large so that the strength of the connection portion is increased, and the insertion hole does not decrease the strength of the connection portion. It is good to make it a size.

  Further, the band attaching means may be configured such that the fixing band can be attached so that the fixing band fixes the attachment member in a state where the attachment plate is pressed against the desired attachment place. It is preferable that the fixing band can be attached so that the fixing band fixes the attachment member in a state of being sandwiched together. For example, when the attachment plate is attached to the frame of a work vehicle such as a forklift, the band attachment means may be configured so that the attachment plate can be fixed together with the frame with a fixed band.

  For example, the band mounting means may be a locking portion that can lock the fixing band. In this case, the mounting plate and the frame are collectively bundled with the fixing band in a state where the fixing band is locked to the locking portion. It is good to have a configuration that is fixed. Also, the band mounting means may be an insertion hole through which the fixed band can be inserted. In this case, with the fixed band inserted, the mounting plate and the frame are fixed together with the fixed band. Good.

  For example, when the fixing band is fixed to the mounting plate together with the frame of the work vehicle such as a forklift, the insertion hole is formed so that the fixing band can be inserted in a direction that can be wound in a direction substantially orthogonal to the longitudinal direction of the frame. Good. In this way, the mounting plate can be easily fixed to the frame, and the fixing band can be shortened.

(4) The mounting plate is connected to the support means so as to be symmetric in a direction orthogonal to the separating direction.

  According to this, when the camera is attached to the desired attachment location so that the desired attachment location and the lens substantially face each other, the lens and the desired attachment location can be brought close to each other. For example, when the camera is attached to the rear glass of the vehicle, it is possible to prevent the camera reflected on the rear glass of the vehicle from being shot. Further, for example, after the lens is attached to a desired attachment location, the lens and the desired attachment location can be brought close to each other in a state where the camera is rotated and the lens faces the desired attachment location.

  As a configuration in which the mounting plate is connected to the support means so as to be symmetric in the direction substantially perpendicular to the separating direction, for example, the central part in the direction orthogonal to the separating direction is more than the other part in the orthogonal direction. Alternatively, it is preferable to connect the outer peripheral surface of the support means to the outer peripheral surface of the support means in a state of being close to the outer peripheral surface of the support means. For example, when the mounting plate has a substantially rectangular shape, the mounting plate may be connected so that the center in the short direction of the mounting plate is closest to the outer peripheral surface of the support means.

(5) The camera has a substantially cylindrical portion, the support means has a rotation support portion that rotatably supports the substantially cylindrical portion, and the mounting plate is substantially in the axial direction of the substantially cylindrical portion. It extends in a direction away from the lens in parallel.

  According to this, when attached to a desired attachment location, the orientation of the camera can be easily changed by rotating the camera relative to the rotation support portion. For example, when the camera lens is provided at the tip of the substantially cylindrical portion in the axial direction (for example, when the shooting direction of the camera is substantially parallel to the axial direction of the substantially cylindrical portion), the image captured by the camera is displayed on the monitor. The image can be adjusted by rotating the camera so that the image when projected is a normally visually recognized image. When the camera lens is provided on the outer peripheral surface of the substantially cylindrical portion (when the shooting direction of the camera is substantially parallel to the direction substantially orthogonal to the axial direction), the axial direction of the substantially cylindrical portion is the center of rotation. The shooting direction of the camera can be easily changed.

  The camera may have a shape having a substantially cylindrical portion in part, and it is further preferable that the camera has a substantially cylindrical shape as a whole. By making the entire camera into a substantially cylindrical shape, changes in the shape of the camera when the camera is rotated can be reduced. For example, even if it is rotated after being attached to the desired mounting location, it can be used without a sense of incongruity Can do. Further, by making the entire camera into a substantially cylindrical shape, for example, the camera can be easily picked, and the camera can be easily rotated when changing the shooting direction. Furthermore, by making the entire camera into a substantially cylindrical shape, the appearance of the camera can be shown cute.

  Alternatively, the entire camera may be formed in a substantially cylindrical shape, and a part on the outer peripheral surface may be cut out to provide a flat portion. In this case, it is preferable to arrange a monitor that projects an image on the plane portion.

  The lens of the camera is preferably disposed at the tip of the substantially cylindrical portion in the axial direction, and more preferably is disposed on the outer peripheral surface of the substantially cylindrical portion.

  When the lens is disposed on the outer peripheral surface of the camera, the lens should be disposed on the outer peripheral surface of the substantially cylindrical portion so as not to protrude at least outward from the mounting plate so that an image is not captured by the outer peripheral surface. It is good to arrange | position on an outer peripheral surface. The camera can be reduced in size by preventing the lens from protruding from the outer peripheral surface as much as possible. In addition, the camera can be refreshed.

  The camera may be configured such that the portion where the rotation support portion is disposed is concave, and when the rotation support portion is attached, the outer peripheral surface of the rotation support portion and the outer peripheral surface of the substantially cylindrical portion are located on substantially the same plane. More preferably, it is configured in such a concave shape. By configuring the outer peripheral surface of the rotation support portion and the outer peripheral surface of the substantially cylindrical portion to be on the same plane, the overall shape of the camera can be made clear.

  For example, when the camera casing is formed of two members, a screw portion that connects the two members may be formed in a concave portion in which the rotation support portion is disposed. By forming the concave portion, the screw portion can be hidden when the rotation support portion is disposed.

  (6) The camera has a hole portion, and a connected portion to which a connection portion of a connection cable can be connected is provided in the hole portion.

  According to this, a to-be-connected part can be hidden. For example, it is possible to prevent the connected portion from being exposed to the outside.

  For example, the hole may be formed so that the connection portion of the connection cable to which the packing is attached can be inserted while the packing is in close contact with the inner wall. By doing in this way, the inside of the hole part in the state where the connection part of the connection cable was connected to the to-be-connected part can be waterproofed. For example, when the connector of the connection portion of the connection cable is an HDMI male connector, the connected portion may be an HDMI female connector to which the HDMI male connector can be connected.

  (7) The connecting portion provided in the hole is provided with guide means capable of guiding the connecting portion of the connection cable.

  According to this, even when the connected portion is provided in the hole, the connecting portion of the connection cable and the connected portion can be easily connected. In other words, even when the connected portion in the hole is not visible, the connecting portion of the connection cable and the connected portion can be easily connected. For example, when the connection portion of the connection cable has a substantially cylindrical shape with respect to the substantially cylindrical hole portion, the connection portion can be easily connected only by searching the guide portion by rotating the connection portion.

  As the guiding means, for example, a projection may be provided at the connection portion of the connection cable, and a groove may be provided on the inner wall of the hole portion so that the projection can be guided toward the connected portion. It is more preferable that a groove is provided and a protrusion that can guide the groove to the connected portion is provided on the inner wall of the hole.

  By providing the groove portion in the connection portion of the connection cable, for example, it becomes easy to attach a packing such as an O-ring to the connection portion of the connection cable.

  In addition, by providing a protrusion on the inner wall of the hole, for example, when the connection portion of the connection cable is mounted in the hole, the connector portion (for example, male connector) of the connection portion of the connection cable is connected. If the connection direction of the part (for example, female connector) does not match, the tip of the mold part of the connection part can come into contact with the protruding part of the hole part, so the connector part provided at the tip of the connection part is unnecessary It is possible to prevent breakage due to contact with the connected portion. In this case, it is preferable that the length of the protruding portion is longer than the length of the connector portion.

  (8) The hole portion is formed at an end portion of the substantially cylindrical portion in the axial direction, and the connected portion is provided so that the connection portion of the connection cable is detachable in the axial direction. It is characterized by that.

  According to this, attachment / detachment of the connection part of the connection cable with respect to a to-be-connected part can be made easy. For example, if the camera has a substantially cylindrical shape, hold the connection part by simply pulling the connection part of the connection cable with the other hand while pulling the connection part of the connection cable with the other hand. Can be pulled out from the connection.

  For example, when the camera has a substantially cylindrical shape and the attachment plate extends in the axial direction, the attachment plate can be made inconspicuous by connecting the connection portion of the connection cable to the connection portion.

  Furthermore, for example, when the camera has a substantially cylindrical shape and the mounting plate extends in the axial direction, the connecting portion of the connecting cable can be attached to and detached from the connecting portion in the axial direction. When attaching and detaching, the attachment plate can be made difficult to peel off from the attachment location.

  For example, the hole portion may be formed in a size that allows a connection portion of a connection cable fitted with a packing such as an O-ring to be inserted, and may have a size such that the packing is appropriately crushed. By forming in this way, the connection location between the connected portion inside the hole and the connection portion of the connection cable can be waterproofed. In this case, it is good to provide the attachment part (for example, attachment groove | channel) which can attach packing, such as an O-ring, to the connection part of a connection cable. Providing the attachment portion makes it difficult for the packing such as an O-ring to come off from the connection portion of the connection cable when the connection portion of the connection cable is inserted into the hole.

  (9) The hole is formed in a deepest portion of the substantially cylindrical portion in the axial direction, and the connected portion is provided so that the connecting portion of the connection cable is detachable in the axial direction. And

  According to this, since the connected portion is provided at the end of the hole portion provided in the axial direction, for example, the connecting portion (for example, HDMI male connector) of the connection cable is connected to the connected portion (for example, HDMI female). Connector).

  (10) The image pickup apparatus described above, a recording apparatus that records image data captured by the camera of the imaging apparatus, and a connection cable that connects the camera and the recording apparatus are provided.

  According to this, the camera can be reduced in size by separately configuring the camera and the recording device that records the video captured by the camera.

  The connection cable may be configured to be connected in a state of being fixed to the camera and the recording device (for example, a state in which the connection cable is not pulled out from the camera and the recording device). By adopting a structure that does not pull out, it is possible to prevent the connection cable from being unnecessarily pulled out from the camera or the recording device. The structure that cannot be pulled out may be a structure that cannot be pulled out from the beginning, or a structure that cannot be pulled out once connected. Moreover, it is good also as a structure which becomes difficult to pull out once it connects. The configuration that makes extraction difficult may be a configuration for the imaging device and the connected portion.

  Moreover, it is good to comprise so that attachment or detachment to either one of a camera and a recording device is more preferable. With this configuration, for example, it is possible to prevent the entire imaging system from being removed or replaced during maintenance or failure.

  The connection cable may have a configuration in which the shape of the molding portion of the connection cable is different between the camera side and the recording device side in the same electrical wiring state. For example, the shape of the mold part on the camera side may be a substantially cylindrical shape, and the shape of the mold part on the recording apparatus side may be a substantially rectangular parallelepiped shape. For example, it is preferable that the connection destination of the connection cable is uniquely determined. By adopting a configuration that makes the shape of the mold part different, for example, the camera side mold part that is to be waterproofed for outdoor installation is made into a substantially cylindrical shape and enters the inside of the camera. When the mold part on the recording apparatus side that is not required to be waterproof is formed in a substantially rectangular parallelepiped shape so as not to enter the inside of the recording apparatus, erroneous connection can be prevented. Furthermore, when it is made a substantially cylindrical shape, it is preferable that the connection direction can be known immediately. For example, a mark indicating the connection direction may be provided.

  (11) The connection cable is configured to be detachable from the imaging device and the recording device.

  According to this, since it is possible to connect the imaging device and the recording device by selecting a connection cable having a required length, depending on the relationship between the mounting location of the imaging device and the installation position of the recording device, etc. It is possible to prevent the length from becoming insufficient or the length from being too long. Further, for example, since the camera can be rotated in a state where the connection cable is not connected, the camera can be easily rotated. For example, when rotating the camera in a narrow place, the connection cable does not get in the way.

  For example, when transmitting a large amount of data such as video, it is possible to prevent the video from being lost by increasing the cable length using the connector. Moreover, it can be prevented that the connection cable is too long.

  In addition, at the time of maintenance or failure, it is possible to individually repair or replace the imaging device, the recording device, and the connection cable.

  The connector portion of the connection portion of the connection cable may be a non-circular connector. For example, it may be a substantially rectangular parallelepiped connector portion. As the connector portion of the connection portion of the connection cable, a standardized connector may be used, and in particular, a connector standardized for a specific application may be used. For example, it is more preferable to use a USB or HDMI cable connector (hereinafter referred to as “HDMI connector”). By using a standardized HDMI connector, the number of pins can be increased in size and cost. In particular, by using pins different from the standard of the standardized connector, for example, in the case of a connector portion of a USB cable, only 5 pins can be taken, but in the case of an HDMI connector, 5 pins or more (for example, 12 pins or more) ) Can be taken. For example, the number of pins may be 8 pins. In particular, it is preferable to use a connector that can transmit both power and video. The power may be supplied from the main body side, or vice versa.

  (12) The camera has a hole, and a connected terminal to which a connection terminal provided at a tip of the connection portion of the connection cable is connectable is provided in the hole. .

  According to this, the connected terminal can be hidden. For example, it is possible to prevent the connected terminal from being exposed to the outside.

  For example, the hole may be formed so that the connection portion of the connection cable to which the packing is attached can be inserted while the packing is in close contact with the inner wall. By doing in this way, the inside of the hole part of the state in which the connection terminal of the connection part of the connection cable was connected to the to-be-connected terminal can be waterproofed. Further, for example, when the connection terminal of the connection portion of the connection cable is an HDMI male connector, the connected terminal may be an HDMI female connector to which the HDMI male connector can be connected.

  (13) The hole portion is formed in a substantially cylindrical shape, and the connection portion of the connection cable is formed in a substantially cylindrical shape that can be mounted in the hole portion in a state where a predetermined packing is mounted. Features.

  According to this, the waterproof performance in the case where packing is interposed between the hole portion and the connection portion of the connection cable can be improved by forming the hole portion and the connection portion of the connection cable in a substantially cylindrical shape.

  For example, the predetermined packing may be an O-ring, and the connection portion may be provided with a mounting groove to which the O-ring can be attached. In this case, the attachment portion may be formed so that a portion where the O-ring is engaged with the attachment portion is larger than a portion where the O-ring is exposed.

  (14) A guide means for guiding the connection terminal of the connection portion to the connected terminal provided in the hole is provided.

  According to this, even when the connected terminal is provided in the hole, the connecting terminal of the connecting portion of the connection cable and the connected terminal can be easily connected. In other words, even when the connected terminal in the hole is not visible, the connection terminal of the connection cable and the connected terminal can be easily connected. For example, when the connection portion of the connection cable has a substantially cylindrical shape with respect to the substantially cylindrical hole portion, the connection portion can be easily connected simply by searching the guide portion by rotating the connection portion.

  As the guiding means, for example, a projection may be provided in the connection portion of the connection cable, and a groove on the inner wall of the hole may be provided to guide the projection toward the connected terminal. It is more preferable that a groove is provided and a protrusion that can guide the groove to the connected terminal is provided on the inner wall of the hole.

  By providing the groove portion in the connection portion of the connection cable, for example, it becomes easy to attach a packing such as an O-ring to the connection portion of the connection cable.

  In addition, by providing a projection on the inner wall of the hole, for example, when the connection portion of the connection cable is mounted in the hole, the connection terminal (for example, male connector) of the connection portion of the connection cable is connected. If the connection direction with the terminal (for example, female connector) does not match, the tip of the connection part can come into contact with the protruding part of the hole. Can be prevented. In this case, for example, the length of the protruding portion may be longer than the length of the connection terminal.

  (15) The guide means includes a guide protrusion provided in the hole portion and a guide groove provided in the connection portion.

  According to this, when the connection portion of the connection cable is mounted in the hole portion, the connection directions of the connection terminal (for example, male connector) and the connection target terminal (for example, female connector) of the connection portion of the connection cable match. If not, the tip of the connecting portion and the protruding portion of the hole can be brought into contact with each other, so that it is possible to prevent the connecting terminal from unnecessarily coming into contact with the connected terminal and being damaged. The guide protrusion may be formed to be longer than the length of the connection terminal in the connection direction.

  (16) The connection portion is provided with a primary insertion portion in which the connection terminal is disposed and the guide groove is formed, and a secondary insertion portion that is located downstream in the insertion direction of the primary insertion portion and to which the predetermined packing is attached. And an insertion portion.

  According to this, the guide protrusion provided in the hole and the guide groove of the connection cable can be engaged before the predetermined packing is attached to the hole. That is, the guide protrusion and the guide groove can be easily engaged. For example, the guide protrusion can be easily found by rotating the connecting portion.

In the following, the desired attachment location is simply referred to as the attachment location.

  As shown in FIGS. 2 and 3, the camera unit 20 includes a mounting bracket (hereinafter simply referred to as “bracket”) 200 that can be mounted at a mounting location, a substantially cylindrical shape, and a bracket that is centered on a central axis A. 200 includes a camera 210 that is rotatably supported by 200, and a fixing member 250 that fixes the camera 210 to the bracket 200 at an arbitrary rotational position.

  That is, the camera unit 20 changes the shooting direction of the camera 210 at the attachment location by rotating the camera 210 relative to the bracket 200 attached at the attachment location, and the camera 210 is attached to the bracket 200 by the fixing member 250. By fixing to the desired position, it is possible to shoot a desired photographic subject from the attachment location.

  In this embodiment, the camera 210 is formed in a substantially cylindrical shape having a diameter of about 33 mm and a length in the direction of the central axis A of about 50 mm. For example, the camera 210 is attached to the rear glass of a vehicle or the frame of a forklift. The size and shape are relatively inconspicuous. For example, the camera 210 according to the present embodiment has a neat shape that is not provided with a liquid crystal monitor, operation buttons, an SD slot, and the like, and is not provided with a fixing hole for attaching a tripod. Yes.

  As shown in FIGS. 4A and 4B, the bracket 200 is formed in a substantially annular shape, and can be attached to a mounting portion and a ring portion 201 that rotatably supports the camera 210 around the central axis A. And a connecting portion 203 that connects the ring portion 201 and the mounting plate 202 to each other.

  The ring portion 201 is formed in a substantially annular shape, and in this embodiment, the length (width) in the direction of the central axis A is about 10 mm, and the length (thickness) in the direction toward the central axis A is about. It is formed in a 2 mm belt-like substantially ring shape.

  The ring unit 201 can be mounted on the base end side in the central axis A direction of the camera 210 (hereinafter simply referred to as “base end side”), and the camera 210 is relative to the ring unit 201 when the camera 210 is mounted. The inner peripheral surface 201b has a diameter (hereinafter, referred to as “inner diameter”) slightly smaller than an outer diameter of a mounting recess 214 (to be described later) of the camera 210 (see, for example, FIG. 5A) so that the rotation is possible. It is formed to be large. In the present embodiment, the inner diameter of the ring part 201 is about 29 mm.

  Further, the diameter of the outer peripheral surface 201a of the ring portion 201 (hereinafter referred to as “outer diameter”) is such that the outer peripheral surface 201a of the ring portion 201 and the outer peripheral surface of the camera 210 are substantially on the same plane when the camera 210 is mounted. The outer diameter of the camera 210 is substantially the same as the outer diameter of the camera 210 (for example, the same diameter, or slightly smaller or larger). In the present embodiment, the outer diameter of the ring portion 201 is about 33 mm, which is the same as the outer diameter of the outer peripheral surface of the camera 210 (see, for example, FIG. 3A).

  Of the side surfaces 201c and 201d orthogonal to the outer peripheral surface 201a and the inner peripheral surface 201b of the ring unit 201, when the camera 210 is mounted on the ring unit 201, the side surface 201c that comes into contact with the camera 210 is provided with a meshing unit 204. ing. The meshing portion 204 is composed of a plurality of serrated concave portions 204a and convex portions 204b formed adjacent to each other in the circumferential direction. On the other hand, nothing is provided on the side surface 201d opposite to the side surface 201c, and it has a substantially planar shape that can come into contact with the fixing member 250.

  As shown in FIG. 4C, the mounting plate 202 is formed in a substantially rectangular plate shape, and when the camera 210 is mounted on the ring portion 201, the longitudinal direction is along the central axis A and the camera 210. It is connected to the ring part 201 via the connecting part 203 so as to extend in a direction away from the lens 231 (see, for example, FIGS. 3A to 3C). In this embodiment, the mounting plate 202 is slightly thinner in the direction away from the lens of the camera 210. The length of the mounting plate 202 in the longitudinal direction is about 39 mm, and the maximum length in the short direction. Is about 28 mm.

  Further, as shown in FIGS. 4C and 4D, the mounting plate 202 extends along the central axis A with the side surface 201 c of the ring portion 201 as a base end, and is short at the base end portion of the mounting plate 202. Notches 205a and 205b are provided on both sides in the hand direction. The shape and range of the cutout portions 205a and 205b are set based on the range of the image captured by the camera 210, and in particular, distortion of the shooting range of the camera 210 caused by the configuration of the optical system or the like is taken into account. Is set. In the present embodiment, the shape and range of the notches 205a and 205b are formed in a substantially rectangular shape taking these into consideration, and the notches 205a and 205b are attached even when the camera 210 is rotated relative to the bracket 200. The plate 202 is not reflected. Further, the notch 205a and the notch 205b are formed so as to be symmetric with respect to the central axis A. In addition, the edge part of the attachment board 202 formed by notching into a substantially rectangular shape is formed in R shape so that a corner may be eliminated.

  A portion of the mounting plate 202 excluding the notches 205a and 205b is provided with a pasting surface 202a to which a double-sided tape for mounting at the mounting location can be pasted. That is, the bracket 200 is configured to be attached to the attachment location by attaching the attachment plate 202 to the attachment location with double-sided tape. The affixing surface 202a is formed in a rectangular shape to which a commercially available double-sided tape or the like can be affixed. Further, the affixing surface 202a protrudes slightly in the thickness direction of the attachment plate 202 from the attachment plate 202, so that the location where the double-sided tape is affixed on the attachment plate 202 can be readily seen.

  Note that the affixing surface 202a has an affixing area where the double-sided tape can exert an adhesive force such that the bracket 200 affixed to the attachment location while supporting the camera 210 is not easily peeled off from the attachment location. In this embodiment, in order to increase the bonding area of the bonding surface 202a, the mounting plate protrudes from the base end of the camera 210 by about 10 mm in a direction substantially flat with the central axis A direction and away from the lens 231. It has a configuration. Depending on the adhesive strength of the double-sided tape, the protruding length can be shortened. By extending the attachment plate 202 in a direction away from the lens 231, the attachment area of the attachment plate 202 can be increased in a state where the base end portion of the attachment plate 202 is as close as possible to the lens 231.

  Further, the mounting plate 202 is connected to the ring portion 201 via the connecting portion 203 so as to be symmetric in the short direction. In other words, when the attachment surface 202a is viewed from the front, the center in the short direction of the attachment plate 202 is connected to the ring part 201 via the connecting part 203 so as to be located on the central axis A. In other words, when the attachment surface 202a is viewed from the side, the center of the attachment plate 202 in the short direction is closest to the ring portion 201, and both sides thereof are symmetrical, and the ring portion 201 is interposed via the connecting portion 203. (See, for example, FIGS. 2E and 2F).

  The connecting portion 203 is interposed between the ring portion 201 and the mounting plate 202, and the connecting portion 203 is provided with an insertion hole 203a through which a binding band (not shown) can be inserted. The insertion hole 203a passes through the connecting portion 203 substantially parallel to the circumferential direction of the ring portion 201, and is formed in a substantially rectangular parallelepiped shape so that a band-like binding band can be inserted. For example, the insertion hole 203a is formed by winding the attachment plate 202 and the frame together with a binding band so that the attachment plate 202 is pressed against the frame when the bracket 200 is attached to the frame of the forklift. Used when fixing to. That is, the insertion hole 203a plays a role of insurance for enabling the use of a binding band for preventing the bracket 200 from falling.

  By providing the insertion hole 203a, for example, when the camera unit 20 is mounted outside the vehicle, the camera unit 20 can be mounted even when the bracket 200 is exposed to wind and rain and the mounting plate 202 is peeled off from the mounting position of the vehicle. It can be prevented from dropping from the mounting location.

  As shown in FIGS. 5 and 6, the camera 210 includes a camera casing 211 and a camera module 229 built in the camera casing 211.

  As shown in FIGS. 5A and 5B, the camera housing 211 is formed in a substantially cylindrical shape having an outer diameter of about 33 mm and a length in the central axis direction of about 50 mm. By making the camera casing 211 into a substantially cylindrical shape, for example, the camera 210 can be easily rotated with respect to the bracket 200, the appearance is clean, and it is small and cute. For example, even if the camera 210 is rotated, there is little change in the outer shape (for example, basically a substantially cylindrical shape when viewed from anywhere), so that it is difficult for the user to feel uncomfortable.

  A lens placement portion 212 in which the lens 231 of the camera module 229 is disposed is provided on the distal end side (hereinafter, simply referred to as “front end side”) in the central axis A direction of the camera housing 2111. The lens placement unit 212 is arranged so that the lens 231 faces in the direction orthogonal to the central axis A, and the lens 231 does not protrude from the mounting surface 202a of the mounting plate 202 in the direction orthogonal to the central axis A. It is formed on the outer peripheral surface 211a of 211 (for example, refer FIG.2 (b) and (c)). The lens placement portion 212 is provided at a substantially central portion in the direction of the central axis A on the outer peripheral surface 211 a of the camera housing 211.

  It should be noted that the outer peripheral surface 211a of the camera housing 211 is a portion that is exposed without being hidden by the bracket 200 and the fixing member 250 when the bracket 200 and the fixing member 250 are attached. The length in the direction of the central axis A is about 30 mm. Further, the length of the portion hidden by the bracket 200 and the fixing member 250 in the central axis A direction is about 20 mm.

  An opening 213 for exposing the lens 231 is formed in the lens placement unit 212, and the lens 231 of the camera module 229 built in the camera housing 211 is formed from the opening 213, as shown in FIG. 6. It is exposed through the packing 232. Note that the opening 213 in the present embodiment is formed in a circular shape having a diameter of about 13 mm. By interposing the packing 232 between the opening 213 and the lens 231 (camera module 229), unnecessary intrusion of water from the opening 213 is prevented.

  Nothing is provided at the distal end side of the lens arrangement portion 212 of the camera housing 211, that is, the distal end portion of the camera housing 211 (the distal end portion of the camera 210), and for example, a double-sided tape or the like can be attached. It is substantially planar.

  On the proximal end side of the lens arrangement portion 212 of the camera housing 211, a mounting recess 214 in which the ring portion 201 of the bracket 200 can be mounted is provided. The mounting recess 214 has an outer periphery so that when the camera 210 is mounted on the ring portion 201 of the bracket 200, the outer peripheral surface 201a of the ring portion 201 and the outer peripheral surface 211a of the camera housing 211 are positioned on the same plane. It is formed in a concave shape with respect to the surface 211a. That is, the mounting recess 214 is formed in a concave shape with respect to the outer peripheral surface 211a by the thickness of the ring portion 201 of the bracket 200 (about 2 mm in this embodiment). Further, the outer diameter of the mounting recess 214 is formed to be slightly smaller than the inner diameter of the ring portion 201 of the bracket 200 so that the ring portion 201 of the bracket 200 can rotate on the mounting recess 214.

  At the boundary between the outer peripheral surface 211a and the mounting recess 214, when the ring portion 201 of the bracket 200 is mounted on the mounting recess 214, the side surface 201c of the ring portion 201 (see, for example, FIG. 4B) can be contacted. The contact surface 215 is erected in a direction orthogonal to the central axis A. The contact surface 215 is formed with a meshing portion 216 that can mesh with the meshing portion 204 of the ring portion 201 in a part of the circumferential direction (in this embodiment, a semicircular region). The meshing portion 216 includes a plurality of concave portions 216a and convex portions 216b adjacent to each other, and meshes with any of the plurality of concave portions 204a and convex portions 204b of the meshing portion 204 of the ring portion 201, whereby the camera 210 and the bracket The relative rotation with 200 is regulated.

  Note that the meshing portion 216 and the meshing portion 204 are formed so as to restrict rotation in increments of 5 degrees. By configuring so as to restrict rotation in increments of 5 degrees, the orientation of the camera 210 can be adjusted to a desired orientation when the camera unit 20 is attached to the vehicle.

  On the proximal end side of the mounting recess 214 of the camera housing 211, a screw portion 217 that can be screwed toward the distal end side is provided. The screw portion 217 is formed in a concave shape with respect to the mounting recess 214, and a regulating surface 218 that regulates the screwing amount of the fixing member 250 in the axial direction is formed at the boundary between the mounting recess 214 and the screw portion 217. It is erected in a direction orthogonal to A.

  Here, the length of the mounting recess 214 in the direction of the central axis A is slightly shorter than the length of the ring member 21 in the direction of the central axis A when the ring portion 201 of the bracket 200 is mounted in the mounting recess 214. Is formed. Therefore, when the ring portion 201 of the bracket 200 is mounted in the mounting recess 214, the above-described restriction surface 218 is positioned inside the side surface 201d of the ring portion 201. Thus, when the fixing member 250 is screwed into the screw portion 217 after the ring portion 201 is attached to the attachment recess 214, the fixing member 250 is not restricted by the restricting surface 218, and the ring portion 201 contacts the fixing member 250. The ring portion 201 can be fixed by being sandwiched between the surfaces 215. At this time, the meshing portion 204 of the ring portion 201 and the meshing portion 216 of the contact surface 215 mesh with each other, and the rotation of the ring portion 201 on the mounting recess 214 is restricted.

  On the other hand, when the screwing amount of the fixing member 250 is reduced, the engagement between the engagement portion 204 of the ring portion 201 and the engagement portion 216 of the contact surface 215 can be released. It can be rotated in steps.

  A proximal end side of the screw portion 217 of the camera housing 211 (a proximal end portion of the camera housing 211) is provided with a distal end portion of a first connection portion 400 (for example, see FIG. 8A) of the connection cable 40 described later. An insertable insertion portion 219 is provided. The insertion portion 219 is formed in a substantially cylindrical shape that passes through the central portion of the screw portion 217 in the direction of the central axis A with the central axis A as the center, and is connected to the inner wall of the screw portion 217 by a plurality of ribs 219a. (For example, see FIG. 5A). In the present embodiment, the insertion portion 219 is connected to the inner wall of the screw portion 217 by eight ribs 219a provided radially. By connecting the screw part 217 and the insertion part 219 with a plurality of ribs 219a, the insertion part 219 can be reinforced without unnecessarily increasing the amount of resin.

  Further, the insertion portion 219 is formed in a size that allows the distal end portion of the first connection portion 400 to which an O-ring 407 (see, for example, FIG. 8A) is attached to be inserted while the O-ring 407 is crushed. . For example, the first connection portion 400 to which the O-ring 407 having a thickness of 1.5 mm is attached is formed in a size that can be inserted while the O-ring is crushed by 0.2 to 0.3 mm. By inserting the first connection part 400 into the insertion part 219 while crushing the O-ring 407, the inside of the insertion part 219 is sealed by the first connection part 400, and the inside of the insertion part 219 can be waterproofed.

  The deepest portion of the insertion portion 219 is located around the mounting recess 214 in the central axis A direction. That is, the insertion portion 219 has a depth up to the mounting recess 214 position, and the distal end portion of the first connection portion 400 can be inserted to the vicinity of the mounting recess 214. Further, an HDMI female connector to which an HDMI male connector (hereinafter simply referred to as “male connector”) 401 (for example, see FIG. 8A) described later of the first connection portion 400 can be connected to the deepest portion of the insertion portion 219. A connector disposition portion 219b (hereinafter simply referred to as “female connector”) 230 is provided (see, for example, FIG. 2F). The connector placement portion 219b is configured by an opening substantially the same shape as the female connector 220, and the male connector 401 of the first connection portion 400 inserted into the insertion portion 219 is connected to the female connector 220 exposed from the opening. It has become. At this time, since the inside of the insertion portion 219 is waterproofed by the O-ring 407, water does not enter the connection portion between the male connector 401 and the female connector 230 from the insertion portion 219.

  In addition, a guide protrusion 221 that guides the male connector 401 of the first connection portion 400 toward the female connector 230 is provided on the inner wall of the insertion portion 219. The guide protrusion 221 is formed substantially parallel to the central axis A from the deepest portion of the insertion portion 219, and engages with a guide groove 408 (for example, see FIG. 8A) described later of the first connection portion 400. Thus, the male connector 401 is directed toward the female connector 230 in a state in which the orientation of the male connector 401 of the first connection portion 400 and the orientation of the female connector 230 are matched (for example, in a state where the outer shape and the pin arrangement are matched). I will guide you. When the first connection portion 400 is inserted into the insertion portion 219, the male connector 401 is guided to the female connector 230 by the guide protrusion 221 and the guide groove 408, so that the female connector 230 is placed at the deepest portion of the insertion portion 219. Even when is provided, the male connector 401 and the female connector 230 can be easily connected. For example, the male connector 401 can be easily connected to the female connector 230 even if the female connector 230 inside the insertion portion 219 is not visible.

  The guide protrusion 221 is provided above the long side of the substantially rectangular female connector 230. Therefore, the guide groove 408 is also provided above the long side of the male connector 401 of the first connection part 400, so that the guide groove 408 is formed in a relatively thick part of the first connection part 400. It has become.

  The guide protrusion 221 is formed so as to be at least longer than the length of the first connection portion 400 in the connection direction of the male connector 401, and when the distal end portion of the first connection portion 400 is inserted into the insertion portion 219. The male connector 401 and the female connector 230 are not directly in contact with each other. Further, the guide protrusion 221 is formed so as to be at least shorter than the length of the first connection portion 400 to an O-ring 407 described later. By making the distance to the O-ring 407 as short as possible, the O-ring 407 can be inserted deeper into the insertion portion 219. For example, the first connection portion 400 inserted into the insertion portion 219 is inserted into the insertion portion 219. It can be difficult to get out of.

  In addition, a mark 222 indicating the position of the guide projection 221 is provided at the entrance of the insertion portion 219, which is an end of the insertion projection 221 on the extension line of the guide projection 221. The mark 222 is located inside the insertion portion 219 to the user. The position of the guide protrusion 221 can be predicted to some extent. In addition, the guide protrusion 221 is disposed on one of the plurality of ribs 219a and an extension line in the radial direction.

  As shown in FIG. 6, the camera housing 211 includes a first housing 211b and a second housing 211c that can be fitted to the first housing 211b. That is, the camera housing 211 can be divided into a first housing 211b and a second housing 211c. The camera housing 211 can take out or house the camera module 229 by dividing the first housing 211b and the second housing 211c.

  The first housing 211b is provided with a screw part 217 and an insertion part 219 integrally formed. Parts other than the screw part 217 and the insertion part 219 (such as the mounting recess 214 and the outer peripheral surface 211a) The first casing 211b and the second casing 211c are substantially equally divided. Therefore, the camera casing 211 is provided with a packing 223 formed along the cross section of the first casing 211b and the second casing 211c between the first casing 211b and the second casing 211c. By doing so, it is configured so that water or the like does not enter between the first housing 211b and the second housing 211c.

  In addition, the first casing 211b and the second casing 211c are fixed while the packing 223 is crushed by fitting the first casing 211b and the second casing 211c and then fastening with screws. It is configured. In the present embodiment, the first housing 211b and the second housing 211c are fixed by four screws 224, and the first housing 211b and the second housing 211c are fixed. There are two screw stoppers on the outer peripheral surface 211 a and two on the mounting recess 214. Specifically, screw holes 225a, 225b, 225c, and 225d through which the screws 224 pass are formed in the outer peripheral surface 211a and the mounting recess 214 of the second casing 211c, and the screw holes 225a are formed inside the first casing 211c. , 225b, 225c, and 225d, screw grooves 226a, 226b, 226c, and 226d are formed.

  The screw 224 is inserted into the screw holes 225a, 225b, 225c, and 225d with a seal washer interposed therebetween, so that intrusion of water or the like from the screw holes 225a, 225b, 225c, and 225d is prevented. It has become. Further, by forming the screw holes 225c and 225d in the mounting recesses 214c and 214d, the screw holes 225c and 225d and the screws 224 in the screw holes 225c and 225d can be hidden when the camera 210 is mounted on the bracket 200. become able to.

  The camera module 229 is disposed so that the female connector 230 is positioned on the central axis A, and is fixed to the first housing 211b so that the female connector 230 is positioned on the central axis A. In the present embodiment, the female connector 230 is disposed so as to be positioned on the central axis A by the combination of the boards, and the screw 227 is screwed into screw holes 228a and 228b formed on the inner surface of the first housing 211b. Thus, the female connector 230 is fixed to the first housing 211b so as to be positioned on the central axis A. As a result, the female connector 230 is positioned at the connector placement portion 219b formed on the central axis A.

  A wide-angle lens is used as the lens 231 of the camera module 229. In the present embodiment, a wide-angle lens having a diagonal of 150 to 170 degrees is used. By using such a wide-angle lens, for example, when mounted on the windshield of a vehicle, it is possible to capture a range up to the extent that a pillow appears at a diagonal of 160 degrees, a vehicle traveling in the right and left lanes, etc. Can be taken. In addition, for example, when it is attached to a work vehicle such as a forklift, it is possible to take a picture including a thing on a road outside the work vehicle such as a forklift. For this reason, it is possible to confirm from a recorded image that a work vehicle such as a forklift has stepped on something, dropped a load, or has a step. In addition, it is possible to confirm the presence / absence of a finger pointing inspection performed by a driver before boarding.

  As shown in FIGS. 7A and 7B, the fixing member 250 is formed in a cap shape that can be attached to the base end portion of the camera 210, and from the base end side of the camera 210 to the screw portion 217. A screw groove 251 is formed on the inner peripheral surface 250a so that it can be screwed. Further, when the fixing member 250 is screwed into the screw portion 217, the outer peripheral surface of the camera 210 (the outer peripheral surface 211a of the camera housing 211) and the outer peripheral surface 250b of the fixing member 250 are substantially on the same plane. The outer diameter of the camera 210 is formed so as to be substantially the same as the outer diameter of the outer peripheral surface of the camera 210 (the outer diameter of the outer peripheral surface 211a of the camera housing 211) (for example, the same diameter or slightly smaller or slightly larger).

  Further, as shown in FIG. 8C, the male connector 401 includes an engaging portion provided on the HDMI female connector (in this embodiment, the female connector 230), similarly to the existing HDMI male connector. Engageable engaged portions 401a and 401b are provided.

  In addition, the first connection unit 400 is small and inexpensive by using an HDMI terminal, so that more pins can be arranged. For example, in the case of a USB terminal, only 5 pins can be taken, but by using an HDMI terminal, pins of 5 pins or more can be arranged. Further, for example, the thickness of the cord portion 430 can be reduced by reducing the number of pins, compared to using an existing HDMI cable having 12 pins.

  In addition, these pins include a power supply pin. The connection cable 40 can supply power from, for example, a device connected to the first connection unit 400 to a device connected to the second connection unit 410. The power can be supplied from the device connected to the second connection unit 410 to the device connected to the first connection unit 400. That is, the connection cable 40 can supply power in both directions. For example, when the second connection unit 410 is connected to a drive recorder that is supplied with power from a cigar socket of a vehicle, and the first connection unit 400 is connected to the camera unit 20, the camera unit 20 is connected via the drive recorder. Power can be received from the cigar socket of the vehicle.

  As shown in FIG. 8A, the mold part 402 is formed in a substantially cylindrical shape, and in order from the distal end side, a primary insertion part 403, a secondary insertion part 404, a handle part 405, and a bellows part. 406. The primary insertion portion 403 is formed so that it can be inserted into the insertion portion 219 without the guide protrusion 221 and the guide groove 408 provided in the insertion portion 219 being engaged with each other. is there. A guide groove 408 is formed in the primary insertion portion 403, and the guide protrusion 221 of the insertion portion 219 and the guide groove 408 of the primary insertion portion 403 are engaged (the guide protrusion 221 enters the guide groove 408). The mold part 402 can be further inserted into the insertion part 219.

  The secondary insertion portion 404 is a portion that can be inserted when the guide protrusion 221 and the guide groove 408 are engaged with each other, and when the male connector 401 and the female connector 230 are connected, the entire portion enters the insertion portion 219. The secondary insertion portion 404 is provided with a mounting groove 404a for mounting the O-ring 407. In this embodiment, the mounting groove 404a that can be mounted so that an O-ring having a thickness of 1.5 mm protrudes 0.5 mm. Is formed. That is, the mounting groove 404a is a groove having a depth of 1.0 mm.

  The handle portion 405 is a portion that is not inserted into the insertion portion 219 even when the male connector 401 and the female connector 230 are connected, and when the primary insertion portion 403 and the secondary insertion portion 404 are inserted into the insertion portion 219, It is the part that the user grabs. The bellows part 406 is provided at the base end of the first connection part 400, and is provided so that the first connection part 400 and the cord part 420 can be moved flexibly.

  The first connection unit 400 is uniquely specified to correspond to the connection target (in the present embodiment, the insertion unit 219).

  As shown in FIG. 1, the second connection portion 410 includes an HDMI male connector (hereinafter simply referred to as “male connector”) 411 and a resin-molded mold portion 412. Since the male connector 411 has the same configuration as the male connector 401, description thereof is omitted. The mold part 412 is formed in a substantially rectangular shape that is substantially similar to the HDMI terminal so that the insertion direction of the male connector can be easily understood in the same manner as the connection part of a general HDMI cable. Further, the mold part 412 is not inserted into a connection part 400 (for example, see FIG. 9A), which will be described later, of the recording apparatus 30. That is, unlike the first connection part 400, the second connection part 410 is configured such that only the male connector 411 is inserted into the connection part 400.

  There are a plurality of connecting cables 40 having different lengths of the cord portion 420. For example, a necessary length according to the distance between the place where the camera unit 20 is placed and the place where the recording device 30 is placed. The one having the code part 420 can be selected as appropriate.

  As shown in FIG. 9A, the recording device 30 is formed in a rectangular box shape, and a plurality of connection portions 300 (four in this embodiment) to which the second connection portion 410 can be connected; An SD card slot section 301 into which an SD card is inserted and a microphone section 302 for recording sound are provided.

  A female connector 303 capable of connecting the male connector 411 of the second connection portion 410 is disposed in the connection portion 300, and the tip of the female connector 303 is exposed. That is, only the male connector 411 is connected to the connection unit 300. In other words, the waterproof process is not performed. The SD card slot unit 301 is provided for recording an image taken by the camera 210 on the loaded SD card. In this embodiment, the camera 210 itself does not have a recording medium, and is configured to be recorded by the recording device 30. Thereby, the camera 210 can be reduced in size. The microphone unit 302 is housed inside the recording device 30 and can record the voice of the worker, the movement of the work vehicle during work, the sound of the luggage processed by the work vehicle, and the like.

  In addition, the sensor unit 5 is connected to the recording apparatus 30, and the sensor unit 5 includes an acceleration sensor and a gyro sensor. The sensor unit 5 has a triangular mark 50 for defining the traveling direction and a horizontal line 51 for defining the horizontal direction. The triangular mark (traveling direction) and the horizontal line ( It is designed to be installed in the same state as the horizontal direction. By providing a gyro sensor, for example, even in a vehicle that is steered by a rear wheel, such as a forklift, the movement of the vehicle (for example, in the case of a forklift, the movement when the rear wheel is steered and rotated) is detected. Will be able to.

  Next, the usage method of the drive recorder 1 comprised as mentioned above is demonstrated, referring FIGS. 10-12. In the following, the case where the above-described drive recorder 1 is used by being attached to the rear glass 101 of the one-box type vehicle 100 and the case where it is used by being attached to a forklift 110 which is an example of a work vehicle will be described.

  First, the case where it uses by attaching to the rear glass 101 of the one-box type vehicle 100 is demonstrated, referring FIG. Here, the camera unit 20 is connected to the drive recorder attached to the windshield of the vehicle 100 in advance via the connection cable 40, and the camera unit 20 is used as a second camera for photographing the rear of the vehicle. Will be described. FIG. 10 is a diagram illustrating a state in which the camera unit 20 according to the present embodiment is attached to the rear glass 101 of the vehicle 100.

  When attaching the camera unit 20 to the rear glass 101, first, the attachment location of the camera unit 20 in the rear glass 101 is determined. Here, when attaching to the rear glass 101, you have to attach to the place which avoided the heat ray 102 arrange | positioned in the rear glass 101. FIG. That is, a place other than the place where the hot wire 102 is disposed is a desired place. In the present embodiment, the rear glass 101 is attached to the upper right end.

  After the attachment location is determined, a connection cable 40 having a length corresponding to the distance between the attachment location and the drive recorder attached to the windshield is prepared. The connection cable 40 is preferably selected and prepared in advance with a length corresponding to the distance. By using a connection cable having a length corresponding to the required distance, for example, the length of the cord is not short, or the cord is not too long to get in the way. In particular, the occurrence of problems such as no video being displayed by extending the cord with the connector is eliminated. This is possible because the camera unit 20 and the connection cable 40 are configured separately.

  When the connection cable 40 is prepared, the release sheet of the double-sided tape attached to the mounting surface 202a of the mounting plate 202 of the bracket 200 is then peeled off so that the central axis A of the ring portion 201 is substantially parallel to the horizontal direction. The attachment plate 202 is attached to the rear glass 101. By pasting in this way, when the camera 210 is supported by the ring unit 201, a wide-angle image of the vehicle in the left-right direction can be taken with the camera 210. For example, the situation of a vehicle traveling in the right and left lanes can be photographed.

  Once the mounting plate 202 is affixed to the rear glass 101, the mounting recess 214 of the camera 210 is then mounted on the ring portion 201. When the mounting recess 214 is mounted on the ring unit 201, the camera 210 is rotated so that the lens 231 of the camera 210 faces the outside of the vehicle. In the present embodiment, the camera 210 is rotated so that the rear glass 101 and the lens 231 face each other. At this time, for example, even if the camera 210 is rotated 360 degrees, the lens 231 does not contact the mounting plate 202. Further, even when the camera 210 faces the rear glass 101, the lens 231 is not hidden by the mounting plate 202 and photographing cannot be performed. Further, since the connection cable 40 is not connected, the camera 210 can be easily rotated. When the camera 210 is rotated, the fixing member 250 is next screwed into the camera 210 to fix the camera 210 to the bracket 200.

  When the camera 210 is fixed to the bracket 200, the first connection part 400 of the connection cable 40 is then connected to the camera 210. Specifically, first, the handle part 405 of the first connection part 400 is picked and the primary insertion part 403 is inserted into the insertion part 219 of the camera 210. When the primary insertion portion 403 is inserted into the insertion portion 219, when the guide protrusion 221 provided on the inner wall of the insertion portion 219 and the guide groove 408 of the primary insertion portion 403 are not engaged, the tip of the primary insertion portion 403 is It abuts on the guide protrusion 221 so that the primary insertion portion 403 cannot be inserted any more. That is, when the connection direction of the male connector 401 and the connection direction of the female connector 230 do not match, the primary insertion portion 403 cannot be inserted more than necessary. At this time, since the length of the male connector 401 provided at the distal end of the primary insertion portion 403 in the insertion direction is shorter than the length of the guide protrusion 221 in the insertion direction, the male connector 401 and the female connector 230 are unnecessary. There is no damage due to contact.

  Next, the user rotates the handle portion 405 with the primary insertion portion 403 inserted into the insertion portion 219 to engage the guide protrusion 221 and the guide groove 408. At this time, since the handle portion 405 is formed in a substantially cylindrical shape, the user can easily rotate the first connection portion 400. In addition, since the first connecting portion 400 includes the bellows portion 406, the burden on the cord portion 420 due to rotation is reduced. At this time, the user may support the camera 210 with the other hand, and the camera 210 is also formed in a substantially cylindrical shape, and can be easily supported. Further, since the insertion portion 219 is provided at the base end portion of the camera 210 and the mounting plate 202 of the bracket 200 extends in a direction away from the base end portion substantially parallel to the central axis A, the first connection portion 400 is rotated. At this time, even when a force acts in a direction away from the rear glass 101 from the base end side, the mounting plate 202 is not easily peeled off from the rear glass 101.

  When the guide protrusion 221 and the guide groove 408 are engaged by the rotation of the first connection part 400, the secondary insertion part 404 can be inserted into the insertion part 219. At this time, first, the portion up to the portion where the O-ring 407 of the secondary insertion portion 404 is attached is inserted, and when the secondary insertion portion 404 is further pushed in from there, the secondary insertion portion 404 is crushed while the O-ring 407 is crushed. Are inserted into the insertion portion 219. By inserting the O-ring 407 into the insertion portion 219 while being crushed, the inside of the insertion portion 219 is sealed, and entry of water or the like is prevented. At this time, since the guide protrusion 221 and the guide groove 408 are engaged with each other, the connection direction of the male connector 401 and the connection direction of the female connector 230 coincide with each other, so that the guide groove 408 is guided by the guide protrusion 221. The male connector 401 and the female connector 230 are connected.

  When the male connector 401 and the female connector 230 are connected, the second connecting portion 410 is then connected to the drive recorder. When the second connection unit 410 is connected to the drive recorder, power is supplied from the drive recorder to the camera 210 via the connection cable 40, and an image taken by the camera 210 can be confirmed on the liquid crystal monitor of the drive recorder. When the video of the camera is displayed on the liquid crystal monitor, the user adjusts the shooting direction of the camera 210 while looking at the liquid crystal monitor. At this time, since notches 205a and 205b are provided at both ends of the mounting plate 202 of the bracket 200 on the lens side, the liquid crystal monitor can be used even when the camera 210 faces the rear glass 101 or the camera 210 is rotated. The mounting plate 202 is not reflected.

  Further, since the camera 210 is formed in a substantially cylindrical shape, it is relatively inconspicuous even when attached to the rear glass 101. Even when the mounting plate 202 extends away from the lens 231, the mounting plate 202 does not stand out because of the configuration in which the first connecting portion 400 is connected to the base end portion of the camera 210.

  Next, the case where the drive recorder 1 is used by being attached to the forklift 110 will be described with reference to FIGS. 11 and 12. FIG. 11 is a view showing a state in which the drive recorder 1 according to the present embodiment is attached to the forklift 110.

  As shown in FIG. 11, when the drive recorder 1 is attached to the forklift 110, the camera unit 20 is mounted on the upper frame 111 of the forklift 110 so that the camera unit 20 can simultaneously display the working state of the forklift 110 and the driver operating the forklift 110. It is attached behind.

  Specifically, first, the release sheet of the double-sided tape affixed to the attachment surface 202a of the attachment plate 202 of the bracket 200 is peeled off, and the attachment plate so that the central axis A of the ring part 201 is substantially parallel to the horizontal direction. 202 is affixed to the lower surface 111 a behind the upper frame 111. By sticking in this way, when the camera 210 is supported by the ring unit 201, the camera 210 can take a wide-angle image in the left-right direction of the forklift.

  When the mounting plate 202 is affixed to the lower surface 111a of the upper frame 111, next, a binding band (not shown) is inserted through the insertion hole 203a and wound around the upper frame 111 so that the mounting plate 202 is pressed against the upper frame 111. Fix it. Thereby, for example, even when the adhesive force of the double-sided tape on the mounting surface 202a is reduced by exposing the bracket 200 to wind and rain, the bracket 200 is prevented from falling off the upper frame 111.

  When the binding band is wound around the upper frame 111, the mounting recess 214 of the camera 210 is then mounted on the ring portion 201. When the mounting recess 214 is mounted on the ring unit 201, the camera 210 is rotated so that the lens 231 of the camera 210 faces the driver. When the lens 231 of the camera 210 is directed toward the driver from the rear of the upper frame 111, the camera and the load placed on the claw 113 of the forklift 110 can be simultaneously photographed by the camera 210. When the rotational position (photographing direction) of the camera 210 is determined, the fixing member 250 is then screwed into the camera 210 to fix the camera 210 to the bracket 200.

  When the camera 210 is fixed to the bracket 200, the recording device 30 is then stored under the sheet 112. By storing the sheet under the sheet 112, the recording device 30 is not wetted by rain. Next, the camera unit 20 and the recording device 30 are connected by a connection cable 40 having a cord length corresponding to the distance between the camera unit 20 and the recording device 30. Specifically, the first connection part 400 of the connection cable 40 is connected to the camera unit 20, and the second connection part 410 is connected to the recording apparatus 30. In addition, since the connection of the 1st connection part 400 to the camera unit 20 is the same as that of the above-mentioned, the description is abbreviate | omitted here.

  As described above, when the first connection portion 400 is connected to the camera 210, the insertion portion 219 is sealed by being inserted into the insertion portion 219 while the O-ring 407 is crushed. Is prevented. Therefore, even in a place exposed to wind and rain such as the upper frame 111 of the forklift 110, it is possible to prevent the camera 210 from being broken due to water or dust entering the camera 210. In the camera 210, the packing 232 is also arranged in the lens arrangement unit 212, and the packing 223 is also arranged between the first casing 211b and the second casing 211c. There is no entry. That is, the camera 210 is completely waterproofed by connecting the first connection unit 400.

  Further, by using the connection cable 40 having a cord length corresponding to the distance between the camera unit 20 and the recording device 30, the cord becomes unnecessarily long and obstructs, or the cord length becomes insufficient. Is prevented. In particular, in the case of a work vehicle such as a forklift, it is possible to prevent an accident or the like from occurring due to an unnecessarily long cord being caught by something.

  When the first connection unit 400 is connected to the camera 210, the second connection unit 410 is then connected to the connection unit 300 of the recording apparatus 30. When the second connecting portion 410 is connected to the recording apparatus 30, the sensor unit 50 is then attached around the seat 112 of the forklift 110. The sensor unit 50 is preferably attached in the vicinity of a location that becomes the center of rotation when the rear wheels are steered with the front wheels of the forklift 110 stopped. In this embodiment, the sheet 112 is attached to the lower side. By attaching to the lower part of the seat 112, it is possible to make the recording of the rotational movement of the forklift 110 closer to the driver's feeling due to the rotation of the forklift 110. When the sensor unit is attached, the attachment is completed by connecting the power source to the recording device 30.

  Next, a reproduction screen when a photographed image photographed by the camera unit 20 attached to the forklift 110 is reproduced on a personal computer or the like will be described with reference to FIG. FIG. 12 is a diagram illustrating a captured image displayed on a liquid crystal monitor using a PC viewer.

  In order to view the video shot by the camera unit 20 and recorded on the SD card of the recording device 30 on a personal computer, it is necessary to download dedicated software to the personal computer. By downloading dedicated software to a personal computer or the like, the photographed image recorded on the SD card can be viewed on the personal computer. Hereinafter, a screen on a personal computer displayed by dedicated software is referred to as a PC viewer.

  As shown in FIG. 12, the PC viewer is composed of four screens. First, a file list screen 60 on which a file list is displayed is arranged on the upper right. On the file list screen 60, a list of files recorded on the SD card is displayed. In the file list, shooting date and time, time, and the like are also displayed.

For example, in FIG. 12, since the camera 210 is attached to the forklift 110, a picture of the forklift is displayed. For example, when the camera 210 is attached to an ordinary automobile, a picture of the ordinary automobile is displayed. When the camera 210 is attached to a motorcycle, the picture of the motorcycle is displayed. Further, for example, when a camera is mounted on a factory line, a picture of the factory line is displayed. Further, as shown in the attachment target display screen 61, the three-dimensional direction and the rotation direction are displayed in X, Y, Z, and W in this picture.

  On the left side of the file list screen 60, that is, on the upper left side of the PC viewer, there is a video screen 62 on which the video of the file selected on the file list screen 60 is shown. For example, in the case where videos shot using a plurality of cameras are recorded, the video screen 62 can simultaneously display videos shot by each camera. For example, when images are taken with four cameras, four screens can be projected simultaneously. In addition, any one of the four screens can be projected larger than the other three, or only the screen of the camera to be projected can be projected.

  In addition, on the video screen, by performing predetermined processing (for example, right-clicking with the cursor placed on the video screen 62, etc.), it can be flipped upside down, flipped left and right, and rotated by OO degrees. . By performing this operation, it is possible to return the video to a state where it is normally viewed even when the captured image is tilted or inverted depending on the direction of the camera. If this operation is performed once, the state in which the rotation function is reflected is maintained even when another file on the file list is reproduced.

  Below the video screen 62, an operation state screen 63 of an imaging target (forklift 110 in FIG. 12) detected by an acceleration sensor and a gyro sensor is arranged. The operation state screen 63 displays the operation of the forklift 110 with numerical values and graphs. The user can check the operation of the forklift 110 by looking at the numerical value and the graph.
