Description

The present invention relates to an imaging device and an imaging system including the imaging device.

Conventionally, there are known imaging devices such as security cameras and drive recorders that can change the shooting direction of a camera mounted at an arbitrary mounting location by changing the orientation of the camera lens with respect to the mounting member. For example, in a drive recorder, a drive recorder main body having a cylindrical portion (hereinafter referred to as a “dorareco main body”) is attached to the windshield of a vehicle with the cylindrical portion horizontal, and is vertically oriented with the horizontal direction as a rotation axis. It is known that the photographing direction can be changed by rotating the image (see, for example, Patent Document 1).

JP-A-2010-105530

Here, the above-mentioned drive recorder is generally attached to the windshield of a vehicle and used for photographing the front of the vehicle, but can it be attached to the rear glass of the vehicle 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 with an attachment member and then the camera is faced with the rear glass, one of the attachment members attached to the rear glass. The part may be reflected in the image taken 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. It was also found that when the camera is attached to the rear glass, there are various problems such as it is desirable to make the camera as small as possible to make it inconspicuous.

Therefore, it is an object of the present invention to provide, for example, a small image pickup device that can be attached to a desired attachment position while preventing reflection of the attachment member, and an image pickup system including the image pickup device.

(1) An imaging device including a camera and a mounting member for mounting the camera at a desired mounting location, wherein the mounting member is abbreviated as a supporting means for supporting the camera and a shooting direction of the camera. An imaging device characterized by having a mounting plate that is configured to be mountable at the desired mounting location on one side orthogonal to the camera and extends in a direction away from the lens of the camera.

According to this, when the camera is mounted at the desired mounting location so that the desired mounting location and the lens are substantially facing each other, the camera is mounted on the image captured by the camera while gaining the mounting area of the mounting plate for the desired mounting location. The lens and the mounting plate can be brought close to each other so that the plate is not reflected. That is, the size of the camera can be reduced while the reflection of the mounting member is prevented.

For example, if the mounting plate is made smaller to eliminate glare, the mounting plate may be easily peeled off or become unstable when it is attached to a desired mounting location with double-sided tape or the like. By extending the lens in the direction away from the lens, the mounting area of the mounting plate can be increased while suppressing the influence on the reflection. That is, the mounting plate can be made difficult to peel off from the desired mounting location and can be stabilized at the desired mounting location.

The desired mounting location may be a desired location in a 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 supporting means may be configured to support the camera so that the direction of the lens of the camera can be changed, and it is even more preferable to support the camera so as to be rotatable. In particular, it is preferable to support the camera so that it can rotate 360 degrees. For example, when the camera has a substantially cylindrical shape, the supporting means may have a ring shape.

When the supporting means supports the camera so as to be rotatable, the camera may be supported so as to rotate smoothly, and the camera may be supported so as to rotate stepwise. For example, the camera may be supported so as to rotate by 5 degrees with respect to the rotation support member.

Further, when the support means rotatably supports the camera, it is preferable to provide a fixing means for fixing the support means at an arbitrary rotation position. As the fixing means, for example, it may be configured to rotate when a rotational torque of more than a predetermined value is applied and to hold a rotational position when a rotational torque of less than a predetermined value is applied. The rotation torque above the predetermined value may be, for example, the rotation torque caused by the user rotating the camera, and the rotation torque below the predetermined value may be the rotation torque acting by vibration of the mounting location (for example, the 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 to sandwich the supporting means.

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

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

The direction away from the lens may be the radial direction with respect to the lens, and in this case, a substantially fan shape is preferable. Further, the direction away from the lens may be such that it extends in one of the radial directions, and in this case, it may have a substantially rectangular shape. For example, when the camera has a substantially cylindrical shape and the lens is arranged 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 the camera does not need to be peeled off from the mounting location when the camera is attached to an arbitrary mounting location with double-sided tape. It suffices to have a sticking area where the double-sided tape can exert its force. In this case, the mounting surface of the mounting plate may be substantially flat, and by making the mounting surface substantially flat, for example, the mounting plate can be easily attached to an arbitrary mounting location with double-sided tape. For example, the length in the direction 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 have a substantially cylindrical portion in a part thereof, and the camera may have a substantially cylindrical shape as a whole. By making the entire camera substantially cylindrical, the change in the shape of the camera when the camera is rotated can be reduced. For example, even if the camera is rotated after being attached to an arbitrary mounting location, it can be used without discomfort. Can be done. Further, by making the entire camera substantially cylindrical, for example, the camera can be easily picked up, and the camera can be easily rotated when the shooting direction is changed. Furthermore, by making the entire camera substantially cylindrical, the appearance of the camera can be made to look cute.

Further, the camera may be configured to use a wide-angle lens, for example, a wide-angle lens having a diagonal of 150 to 170 degrees may be used. For example, when it is attached to the windshield of a car, it is possible to shoot a range up to the extent that the pillow is reflected at a diagonal of 160 degrees, and it is possible to shoot 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 vehicle on the road outside the work vehicle such as a forklift. Therefore, it can be confirmed from the recorded video that the work vehicle such as a forklift stepped on something, dropped the luggage, or had a step.

(2) The mounting plate is characterized by having notches at both ends on the lens side in a direction substantially orthogonal to the away direction when the mounting plate is located on the one side of the camera.

According to this, the lens and the mounting member can be brought closer to each other than when the notch is not provided. For example, the mounting plate can be placed in the immediate vicinity of the lens. That is, the camera unit can be further miniaturized. In particular, even when a wide-angle lens is used, by cutting out both ends on the lens side, the lens and the mounting plate can be brought close to each other without the mounting plate being reflected 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 taken by the camera, and in particular, a shape and / or a shape that takes into account the distortion of the shooting range of the camera caused by the configuration of the optical system or the like. Or it may be a range.

For example, the shape of the notch may be rectangular, and by notching in a rectangular shape, the notch can be formed more easily and reliably.

(3) The mounting member is characterized by having a band mounting means capable of mounting a fixing band for fixing the mounting member mounted at the desired mounting location to the desired mounting location.

According to this, the mounting member attached to the desired mounting location can be fixed with a fixing band so as not to fall off from the desired mounting location. For example, even when the adhesive strength of the double-sided tape is reduced when the mounting member is attached to the outside of the vehicle with double-sided tape, it is possible to prevent the mounting member from falling off from a desired mounting location.

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

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

Further, it may be provided at the connecting portion between the mounting plate and the supporting means. When the band mounting means is provided at the connecting portion between the mounting plate and the supporting means, it is preferable to provide the band mounting means so that the strength of the connecting portion does not decrease. For example, when the connecting portion is provided with an insertion hole through which the fixing band can be inserted, the connecting portion may be made larger so that the strength of the connecting portion is increased, and the insertion hole is provided to the extent that the strength of the connecting portion is not reduced. It is good to make it the size of.

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

For example, as the band mounting means, it is preferable that the fixing band is a locking portion that can be locked. In this case, the mounting plate and the frame are collectively held by the fixing band with the fixing band locked to the locking portion. It is good to have a structure to fix it. Further, as the band mounting means, it is preferable to use an insertion hole through which the fixing band can be inserted. In this case, the mounting plate and the frame are collectively fixed by the fixing band with the fixing band inserted. Good.

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

(4) The mounting plate is characterized in that it is connected to the supporting means so as to be symmetrical in a direction orthogonal to the separating direction.

According to this, when the camera is mounted at the desired mounting location so that the desired mounting location and the lens are substantially facing each other, the lens and the desired mounting 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 photographed. Further, for example, after mounting the lens at a desired mounting location, the lens can be brought close to the desired mounting location in a state where the camera is rotated so that the lens faces the desired mounting location.

As a configuration in which the mounting plate is connected to the support means so as to be symmetrical in a direction substantially orthogonal to the separation direction, for example, the central portion in the direction orthogonal to the separation direction is more than another portion in the orthogonal direction. Also, it is preferable to connect to the outer peripheral surface of the supporting means in a state of being close to the outer peripheral surface of the supporting means. For example, when the mounting plate has a substantially rectangular shape, it is preferable that the center of the mounting plate in the lateral direction is connected so as to be closest to the outer peripheral surface of the supporting means.

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

According to this, when the camera is mounted at a desired mounting location, the direction 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 used as a monitor. The camera can be rotated and adjusted so that the projected image is a normally visible 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 defined as the center of rotation. You can easily change the shooting direction of the camera.

The camera may have a shape having a substantially cylindrical portion in a part thereof, and it is more preferable that the camera has a substantially cylindrical shape as a whole. By making the entire camera substantially cylindrical, it is possible to reduce the change in the shape of the camera when the camera is rotated. For example, even if the camera is rotated after being mounted at a desired mounting location, it can be used without discomfort. Can be done. Further, by making the entire camera substantially cylindrical, for example, the camera can be easily picked up, and the camera can be easily rotated when the shooting direction is changed. Furthermore, by making the entire camera substantially cylindrical, the appearance of the camera can be made to look cute.

Further, the entire camera may have a substantially cylindrical shape, and a flat portion may be provided by cutting out a part on the outer peripheral surface. In this case, it is preferable to arrange a monitor for displaying an image on a flat surface portion.

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

When arranging the lens on the outer peripheral surface of the camera, the lens should be arranged on the outer peripheral surface of the substantially cylindrical portion so as not to protrude outward from at least the mounting plate so that the image is not blurred by the outer peripheral surface. It is preferable to dispose of it on the outer peripheral surface. The size of the camera can be reduced by preventing the lens from protruding from the outer peripheral surface as much as possible. You can also keep your camera clean.

The camera may have a concave portion in which the rotation support portion is arranged, 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. It is even better to configure it 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 located on the same plane, the overall shape of the camera can be made neat.

Further, for example, when the housing of the camera is formed of two members, the screw portion connecting the two members may be formed in a concave portion in which the rotation support portion is arranged. By forming the concave portion, the screw portion can be hidden when the rotation support portion is arranged.

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

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

The hole may be formed, for example, 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 so, it is possible to make the inside of the hole portion in which the connection portion of the connection cable is connected to the connected portion waterproof. Further, 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 an HDMI male connector can be connected.

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

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

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

By providing a groove 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.

Further, by providing a protrusion on the inner wall of the hole, for example, when the connection part of the connection cable is attached to the hole, it is connected to the connector part (for example, a male connector) of the connection part of the connection cable. If the connection directions of the parts (for example, female connector) do not match, the tip of the mold part of the connection part can come into contact with the protrusion of the hole, so the connector part provided at the tip of the connection part becomes unnecessary. It is possible to prevent damage or the like by contacting the connected portion. In this case, the length of the protrusion may be longer than the length of the connector.

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

According to this, it is possible to easily attach / detach the connection portion of the connection cable to the connected portion. For example, if the camera is approximately cylindrical, you can cover the connection by simply pinching the cylindrical part of the camera with one hand and the connection part of the connection cable with the other hand, and then pulling it in the opposite direction to the camera. It can be pulled out from the connection.

Further, for example, when the camera has a substantially cylindrical shape and the mounting plate extends in the axial direction, the mounting plate can be made inconspicuous by connecting the connecting portion of the connecting cable to the connected portion.

Further, 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 and detached in the axial direction with respect to the connected portion, so that the connecting portion of the connecting cable It is possible to prevent the mounting plate from peeling off from the mounting location when attaching or detaching the mounting plate.

The hole portion may be formed in a size that allows the connection portion of the connection cable fitted with the packing such as an O-ring to be inserted, and the hole portion may be formed in a size that allows the packing to be appropriately crushed. By forming in this way, it is possible to make the connection portion between the connected portion inside the hole portion and the connection portion of the connection cable waterproof. In this case, it is preferable to provide a mounting portion (for example, a mounting groove) to which a packing such as an O-ring can be attached to the connecting portion of the connection cable. By providing the mounting portion, the packing such as the O-ring is less likely to come off from the connecting portion of the connecting cable when the connecting portion of the connecting cable is inserted into the hole portion.

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

According to this, since the connected portion is provided at the end of the hole provided in the axial direction, for example, the connecting portion (for example, HDMI male connector) of the connecting cable is connected to the connected portion (for example, HDMI female). It can be made difficult to disconnect from the connector).

(10) It is characterized in that it includes the above-mentioned imaging device, a recording device for recording image data taken by the camera of the imaging device, and a connection cable for connecting the camera and the recording device.

According to this, the camera can be miniaturized by separately configuring the camera and the recording device for recording the image captured by the camera.

The connection cable may be configured to be connected to the camera and the recording device in a fixed state (for example, a state in which the connection cable cannot be pulled out from the camera and the recording device). By making the configuration so that it cannot be pulled out, it is possible to prevent the connection cable from being unnecessarily pulled out from the camera or recording device. The configuration that cannot be pulled out may be a configuration that cannot be pulled out from the beginning, or a configuration that cannot be pulled out once connected. Further, once connected, it may be configured to be difficult to pull out. The configuration that makes it difficult to pull out may be a configuration for the imaging device and the connected portion.

Further, it is preferable that the camera and the recording device are detachably attached to each other, and it is more preferable that the camera is detachably attached to the camera. With such a configuration, it is possible to prevent the entire imaging system from being removed or replaced, for example, at the time of maintenance or failure.

Further, the connection cable may have a configuration in which the shape of the molded portion of the connection cable is different between the camera side and the recording device side while the electrical wiring is the same. For example, the shape of the mold portion on the camera side may be a substantially cylindrical shape, and the shape of the mold portion on the recording device side may be a substantially rectangular parallelepiped shape. For example, it is preferable to have a configuration in which the connection destination of the connection cable is uniquely determined. By making the shape of the mold part different, for example, the mold part on the camera side that you want to make waterproof for outdoor installation is made into a substantially cylindrical shape so that it can enter the inside of the camera, and the mounting location is for waterproofing. When the mold portion on the recording device side that does not require waterproofing is formed into a substantially rectangular parallelepiped shape so as not to enter the inside of the recording device, it is possible to prevent accidental connection. Further, when the shape is substantially cylindrical, 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 characterized in that it is detachably configured in the imaging device and the recording device.

According to this, it is possible to select a connection cable of a required length and connect the image pickup device and the recording device. Therefore, depending on the relationship between the mounting location of the image pickup device and the mounting position of the recording device, the connection cable can be connected. It is possible to prevent the length from becoming insufficient or being too long. Further, for example, since the camera can be rotated without connecting the connection cable, 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 a video, it is possible to prevent the video from being displayed by lengthening the cable length using a connector. In addition, it is possible to prevent the connection cable from becoming an obstacle due to being too long.

In addition, the image pickup device, the recording device, and the connection cable can be individually repaired or replaced at the time of maintenance or failure.

The connector portion of the connection portion of the connection cable may be a non-circular connector. For example, a connector portion having a substantially rectangular parallelepiped shape may be used. A standardized connector may be used as the connector portion of the connection portion of the connection cable, 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 with a small size and low cost. In particular, using a pin different from the standardized connector standard, for example, in the case of the connector part 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. The number of pins may be, for example, 8 pins. In particular, it is preferable to use a connector capable of transmitting both power and video. Power may be supplied from the main body side, or conversely, power may be supplied to the main body from the camera.

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

The hole may be formed, for example, 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 so, it is possible to make the inside of the hole portion in which the connection terminal of the connection portion of the connection cable is connected to the connected terminal waterproof. Further, the connected terminal may be, for example, an HDMI female connector to which an HDMI male connector can be connected when the connection terminal of the connection portion of the connection cable is an HDMI male connector.

(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 attached to the hole portion with a predetermined packing attached. It is a feature.

According to this, by making the hole portion and the connection portion of the connection cable substantially cylindrical, it is possible to improve the waterproof performance when the packing is interposed between the hole portion and the connection portion of the connection cable.

The predetermined packing may be, for example, 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 mounting portion may be formed so that the portion where the O-ring is engaged with the mounting portion is larger than the 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 portion, the connection terminal of the connecting portion of the connection cable and the connected terminal can be easily connected. In other words, the connection terminal of the connection cable and the connected terminal can be easily connected even when the connected terminal in the hole cannot be seen. For example, when the connection portion of the connection cable has a substantially cylindrical shape with respect to the substantially cylindrical hole portion, it can be easily connected to the connected terminal simply by rotating the connection portion and searching for the guide portion.

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

By providing a groove 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.

Further, by providing a protrusion on the inner wall of the hole, for example, when the connection part of the connection cable is attached to the hole, it is connected to the connection terminal (for example, a male connector) of the connection part of the connection cable. 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 protrusion of the hole, so the connection terminal is unnecessary to come into contact with the connected terminal and be damaged. It can be prevented from doing so. In this case, for example, the length of the protrusion may be longer than the length of the connection terminal.

(15) The guide means is characterized by having 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 attached to the hole portion, the connection directions of the connection terminal (for example, male connector) and the connected 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 being unnecessarily contacted with the connected terminal and being damaged. The guide protrusion may be formed so as to be longer than the length of the connection terminal in the connection direction.

(16) The connection portion is located at the primary insertion portion where the connection terminal is arranged and the guide groove is formed, and the secondary insertion portion downstream of the insertion direction of the primary insertion portion, and the predetermined packing is mounted. It is characterized by having an insertion portion.

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

According to the present invention, for example, it is possible to provide a small image pickup apparatus that can be attached to a desired attachment position while preventing reflection of the attachment member, and an image pickup system including the image pickup apparatus.

For example, the camera 210 according to the present embodiment has a neat shape that is not provided with a liquid crystal monitor, an operation button, an SD slot, or the like, and is not provided with a fixing hole for mounting a tripod. There is.

As shown in FIGS. 4A and 4B, the bracket 200 is formed in a substantially annular shape and can be attached to a ring portion 201 that rotatably supports the camera 210 about the central axis A and an attachment location. The mounting plate 202 and the connecting portion 203 for connecting the ring portion 201 and the mounting plate 202 are provided.

The ring portion 201 is formed in a substantially annular shape, and in the present 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 about 10. It is formed in a substantially annular shape in the shape of a 2 mm band.

The ring portion 201 can be mounted on the base end side (hereinafter, simply referred to as “base end side”) in the central axis A direction of the camera 210, and when the camera 210 is mounted, the camera 210 is relative to the ring portion 201. The diameter of the inner peripheral surface 201b (hereinafter referred to as “inner diameter”) is slightly larger than the outer diameter of the mounting recess 214 described later (see, for example, FIG. 5A) of the camera 210 so as to be rotatable. It is formed to be large. In the present embodiment, the inner diameter of the ring portion 201 is formed to be 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 when the camera 210 is mounted, 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. It is formed so as to be located at substantially the same diameter as the outer diameter of the outer peripheral surface 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 formed to be about 33 mm, which is the same diameter 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 portion 201, the meshing portion 204 is provided on the side surface 201c that comes into contact with the camera 210 when the camera 210 is attached to the ring portion 201. 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 the side surface 201d has a substantially planar shape capable of contacting 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 camera 210 is oriented in the longitudinal direction along the central axis A. It is connected to the ring portion 201 via the connecting portion 203 so as to extend in the direction away from the lens 231 of the lens 231 (see, for example, FIGS. 3A to 3C). In the present embodiment, the mounting plate 202 is slightly narrowed in the direction away from the lens of the camera 210, and the length of the mounting plate 202 in the longitudinal direction is about 39 mm, which is the maximum length in the lateral direction. Is formed to be 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 201c of the ring portion 201 as the 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 manual direction. The shapes and ranges of the cutouts 205a and 205b are set based on the range of the image captured by the camera 210, and in particular, the distortion of the imaging range of the camera 210 caused by the configuration of the optical system or the like is taken into consideration. It has been set. In the present embodiment, the shapes and ranges of the cutouts 205a and 205b are formed in a substantially rectangular shape in consideration of these, and even when the camera 210 is rotated relative to the bracket 200, it is attached. The board 202 is not reflected. Further, the notch portion 205a and the notch portion 205b are formed so as to be symmetrical with respect to the central axis A. The end portion of the mounting plate 202 formed by notching in a substantially rectangular shape is formed in an R shape so as to have no corners.

A sticking surface 202a to which a double-sided tape for attaching to the mounting portion can be attached is provided on a portion of the mounting plate 202 excluding the cutouts 205a and 205b. 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 sticking surface 202a is formed in a rectangular shape to which a commercially available double-sided tape or the like can be stuck. Further, the sticking surface 202a protrudes slightly from the mounting plate 202 in the thickness direction of the mounting plate 202, so that the place where the double-sided tape is stuck on the mounting plate 202 can be immediately identified.

It should be noted that the sticking surface 202a has a sticking area on which the double-sided tape can exert an adhesive force such that the bracket 200 stuck to the mounting place while supporting the camera 210 does not easily peel off from the mounting place. Often, in the present embodiment, in order to increase the sticking area of the sticking surface 202a, the mounting plate protrudes from the base end portion 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 is composed. Depending on the adhesive strength of the double-sided tape, the protruding length can be shortened. By extending the mounting plate 202 in the direction away from the lens 231, the mounting area of the mounting plate 202 can be increased while the base end portion of the mounting plate 202 is as close to the lens 231 as possible.

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

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 penetrates 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-shaped binding band can be inserted. For example, in the insertion hole 203a, when the bracket 200 is attached to the frame of a forklift, the attachment plate 202 and the frame are collectively wound with a binding band so that the attachment plate 202 is pressed against the frame, and the attachment plate 202 is framed. It is used when fixing to. That is, the insertion hole 203a serves as an insurance for enabling the binding band to be used 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 removed even when the mounting plate 202 is peeled off from the mounting location of the vehicle due to the bracket 200 being exposed to wind and rain or the like. It is possible to prevent the camera from falling from the mounting location.

As shown in FIGS. 5 and 6, the camera 210 includes a camera housing 211 and a camera module 229 built in the camera housing 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 housing 211 substantially cylindrical, for example, the camera 210 can be easily rotated with respect to the bracket 200, the appearance is neat, and the size is small and cute. Further, for example, even if the camera 210 is rotated, there is little change in the outer shape (for example, it is basically a substantially cylindrical shape when viewed from anywhere), so that it is difficult for the user to feel a sense of discomfort.

A lens arranging portion 212 on which the lens 231 of the camera module 229 is arranged is provided on the tip side (hereinafter, simply referred to as “tip side”) of the camera housing 2111 in the direction of the central axis A. The lens arranging portion 212 is a camera housing 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 (see, for example, FIGS. 2B and 2C). Further, the lens arrangement portion 212 is provided on the outer peripheral surface 211a of the camera housing 211 at a substantially central portion in the central axis A direction.

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. In the present embodiment, this portion is exposed. 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 arrangement portion 212, and as shown in FIG. 6, the lens 231 of the camera module 229 built in the camera housing 211 is formed from the opening 213. It is designed to be exposed via the packing 232. 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), it is possible to prevent unnecessary water from entering through the opening 213.

Nothing is provided on the tip side of the lens arrangement portion 212 of the camera housing 211, that is, the tip portion of the camera housing 211 (tip portion of the camera 210), and for example, double-sided tape or the like can be attached. It is almost flat.

A mounting recess 214 to which the ring portion 201 of the bracket 200 can be mounted is provided on the base end side of the lens arrangement portion 212 of the camera housing 211. The mounting recess 214 is provided 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 located 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 so as 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, it can come into contact with the side surface 201c of the ring portion 201 (see, for example, FIG. 4B). 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 capable of meshing with the meshing portion 204 of the ring portion 201 in a part in the circumferential direction (in the present embodiment, a semicircular region). The meshing portion 216 is composed of a plurality of concave portions 216a and convex portions 216b adjacent to each other, and by meshing with any of the plurality of concave portions 204a and convex portions 204b of the meshing portion 204 of the ring portion 201, the camera 210 and the bracket It regulates the rotation relative to 200.

The meshing portion 216 and the meshing portion 204 are formed so as to regulate the rotation in increments of 5 degrees. By configuring so as to regulate the 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.

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

Here, the length of the mounting recess 214 in the central axis A direction is slightly shorter than the length of the ring member 21 in the central axis A direction when the ring portion 201 of the bracket 200 is mounted in the mounting recess 214. Is formed in. Therefore, when the ring portion 201 of the bracket 200 is mounted in the mounting recess 214, the above-mentioned regulation surface 218 is located inside the side surface 201d of the ring portion 201. As a result, when the fixing member 250 is screwed into the screw portion 217 after mounting the ring portion 201 in the mounting recess 214, the ring portion 201 comes into contact with the fixing member 250 without being restricted by the regulation surface 218. It is sandwiched between the surface 215 and the ring portion 201 can be fixed. 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 meshing portion 204 of the ring portion 201 and the meshing portion 216 of the contact surface 215 can be disengaged. For example, the ring portion 201 is 5 on the mounting recess 214. It becomes rotatable in increments.

On the base end side of the screw portion 217 of the camera housing 211 (base end portion of the camera housing 211), the tip end portion of the first connection portion 400 (for example, see FIG. 8A) of the connection cable 40, which will be described later, is attached. An insertable portion 219 is provided. The insertion portion 219 is formed in a substantially cylindrical shape centering on the central axis A and penetrating the central portion of the screw portion 217 in the direction of the central axis A, and is connected to the inner wall of the screw portion 217 by a plurality of ribs 219a. (See, for example, FIG. 5 (a)). 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 portion 217 and the insertion portion 219 with a plurality of ribs 219a, the insertion portion 219 can be reinforced without unnecessarily increasing the amount of resin.

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

The deepest portion of the insertion portion 219 is located around the mounting recess 214 in the direction of the central axis A. That is, the insertion portion 219 has a depth up to the mounting recess 214, and the tip of the first connection portion 400 can be inserted up to the mounting recess 214. Further, an HDMI female connector to which an HDMI male connector (hereinafter, simply referred to as “male connector”) 401 (see, for example, FIG. 8A) of the first connection portion 400, which will be described later, can be connected to the deepest portion of the insertion portion 219. A connector arranging portion 219b (hereinafter, simply referred to as a “female connector”) can be provided (see, for example, FIG. 2 (f)). The connector arranging portion 219b is formed by an opening having substantially the same shape as the female connector 220, and the male connector 401 of the first connecting 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 kept waterproof 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.

Further, on the inner wall of the insertion portion 219, a guide protrusion 221 for guiding the male connector 401 of the first connection portion 400 toward the female connector 230 is provided. 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 the guide groove 408 (see, for example, FIG. 8A) described later of the first connection portion 400. Then, in a state where 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, the outer shape and the pin arrangement are matched), the male connector 401 is directed toward the female connector 230. 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 at the deepest portion of the insertion portion 219. The male connector 401 and the female connector 230 can be easily connected even when the above is arranged. 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 cannot be seen.

Further, the guide protrusion 221 is provided above the long side of the substantially rectangular female connector 230.

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, the handle portion 405 is not inserted into the insertion portion 219. It is the part that the user grasps. The bellows portion 406 is provided at the base end of the first connection portion 400, and is provided so that the first connection portion 400 and the cord portion 420 can be flexibly moved.

The first connection unit 400 is designed so that the correspondence with the connection target (insertion unit 219 in the present embodiment) is uniquely specified.

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, the description thereof will be omitted. The mold portion 412 is formed in a substantially rectangular shape similar to the HDMI terminal so that the insertion direction of the male connector can be easily understood, similarly to the connection portion of a general HDMI cable. Further, the mold portion 412 is not inserted into the connection portion (for example, see FIG. 9A) 400 described later of the recording device 30. That is, unlike the first connection portion 400, the second connection portion 410 is configured such that only the male connector 411 is inserted into the connection portion 400.

The connection cable 40 has a plurality of cord portions 420 having different lengths, and for example, a required length is required according to the distance between the place where the camera unit 20 is arranged and the place where the recording device 30 is arranged. The one having the code portion 420 of the above can be appropriately selected.

As shown in FIG. 9A, the recording device 30 is formed in a rectangular box shape, and has a plurality of connection portions 300 (four in the present embodiment) to which the second connection portion 410 can be connected. It is configured to include an SD card slot section 301 into which an SD card is mounted and a microphone section 302 for recording sound.

The connection portion 300 is provided with a female connector 303 to which the male connector 411 of the second connection portion 410 can be connected, and the tip of the female connector 303 is exposed. That is, only the male connector 411 is connected to the connection portion 300. In other words, the configuration is not waterproofed. The SD card slot portion 301 is provided for recording an image taken by the camera 210 on the attached SD card. In the present embodiment, the camera 210 itself does not have a recording medium and is configured to be recorded by the recording device 30. As a result, the camera 210 can be miniaturized. 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 luggage processed by the work vehicle, and the like.

Further, a sensor unit 5 is connected to the recording device 30, and an acceleration sensor and a gyro sensor are built in the sensor unit 5. A triangular mark 50 for defining the traveling direction and a horizontal line 51 for defining the horizontal direction are drawn on the sensor unit 5, and the triangular mark (traveling direction) and the horizontal line (the traveling direction) and the horizontal line (for the vehicle to be actually mounted) are drawn. It is designed to be installed so that it matches the horizontal direction). By providing a gyro sensor, for example, even in a vehicle steered by the rear wheels such as a forklift, the movement of the vehicle (for example, in the case of a forklift, the movement when the rear wheels are steered to perform a rotating motion, etc.) is detected. You will be able to.

Next, a method of using the drive recorder 1 configured as described above will be described with reference to FIGS. 10 to 12. In the following, a case where the above-mentioned drive recorder 1 is attached to the rear glass 101 of the one-box type vehicle 100 and a case where the drive recorder 1 is attached to a forklift 110 which is an example of a work vehicle will be described.

First, a case where the one-box type vehicle 100 is attached to the rear glass 101 for use will be described with reference to FIG. Here, when 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 using. FIG. 10 is a diagram showing 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 on the rear glass 101 is determined. Here, when it is attached to the rear glass 101, it must be attached to a place avoiding the heat ray 102 arranged on the rear glass 101. That is, a place other than the place where the heat ray 102 is arranged becomes a desired place. In this embodiment, it is attached to the upper right end of the rear glass 101.

After the mounting location is determined, next, a connection cable 40 having a length corresponding to the distance between the mounting location and the drive recorder mounted on the windshield is prepared. It is preferable that the connection cable 40 has a length corresponding to the distance and is prepared in advance. By using a connection cable that is as long as the required distance, for example, the cord will not be too long or too long to get in the way. In particular, by extending the cord with the connector, problems such as the image not being displayed are eliminated. This is possible because the camera unit 20 and the connection cable 40 are separately configured.

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

When the mounting plate 202 is attached 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 portion 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 come into contact with the mounting plate 202. Further, even if the camera 210 faces the rear glass 101, the lens 231 is not hidden by the mounting plate 202 and shooting 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 then screwed into the camera 210 to fix the camera 210 to the bracket 200.

After fixing the camera 210 to the bracket 200, the first connection portion 400 of the connection cable 40 is then connected to the camera 210. Specifically, first, the handle portion 405 of the first connection portion 400 is pinched, and the primary insertion portion 403 is inserted into the insertion portion 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 inserted. It comes into contact with the guide protrusion 221 and the primary insertion portion 403 cannot be inserted any more. That is, if 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. Further, at this time, since the length of the male connector 401 provided at the tip 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. It will not come into contact and be damaged.

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. Further, since the first connection portion 400 includes the bellows portion 406, the burden on the cord portion 420 due to rotation is reduced. Further, at this time, the user may support the camera 210 with the other hand, and since the camera 210 is also formed in a substantially cylindrical shape, it 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 that time, even when a force is applied in the direction away from the rear glass 101 from the base end side, the mounting plate 202 does not easily peel 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 portion 400, the secondary insertion portion 404 can be inserted into the insertion portion 219. At this time, first, the front of the portion where the O-ring 407 of the secondary insertion portion 404 is mounted is inserted, and when the secondary insertion portion 404 is further pushed in from there, the O-ring 407 is crushed and the secondary insertion portion 404 is crushed. Is 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 water or the like is prevented from entering. At this time, by engaging the guide protrusion 221 and the guide groove 408, the connection direction of the male connector 401 and the connection direction of the female connector 230 match, 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 connection 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 the image captured by the camera 210 can be confirmed on the liquid crystal monitor of the drive recorder. When the image of the camera is projected 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 the notches 205a and 205b are provided at both ends of the mounting plate 202 of the bracket 200 on the lens side, the LCD monitor can be used even when the camera 210 is facing 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. Further, even when the mounting plate 202 extends in the direction away from the lens 231 because the first connecting portion 400 is connected to the base end portion of the camera 210, the mounting plate 202 does not stand out.

Next, a case where the drive recorder 1 is attached to the forklift 110 and used will be described with reference to FIGS. 11 and 12. FIG. 11 is a diagram 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 simultaneously displays the working state of the forklift 110 and the driver driving the forklift 110, so that the camera unit 20 can display the upper frame 111 of the forklift 110. It is attached to the back of.

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

When the mounting plate 202 is attached to the lower surface 111a of the upper frame 111, the mounting plate 202 is then pressed against the upper frame 111 by inserting a binding band (not shown) through the insertion hole 203a and winding it around the upper frame 111. Fix it. As a result, for example, even if the bracket 200 is exposed to wind and rain and the adhesive strength of the double-sided tape on the mounting surface 202a is reduced, the bracket 200 is prevented from falling off from 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 portion 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 driver and the luggage placed on the claw 113 of the forklift 110 can be simultaneously photographed by the camera 210. When the rotation position (shooting 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.

After fixing the camera 210 to the bracket 200, the recording device 30 is then housed under the sheet 112. By storing it under the sheet 112, the recording device 30 will not get wet in the 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 portion 400 of the connection cable 40 is connected to the camera unit 20, and the second connection portion 410 is connected to the recording device 30. Since the connection of the first connection unit 400 to the camera unit 20 is the same as described above, the description thereof will be omitted here.

As described above, when the first connection portion 400 is connected to the camera 210, the inside of the insertion portion 219 is sealed by inserting the O-ring 407 into the insertion portion 219 while being crushed, so that rain, dust, etc. invade. 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 damaged due to water or dust entering the inside of the camera 210. In the camera 210, the packing 232 is also arranged in the lens arrangement portion 212, and the packing 223 is also arranged between the first housing 211b and the second housing 211c, so that rain, dust, etc. can be removed from here. There is no entry. That is, the camera 210 becomes completely waterproof by connecting the first connection portion 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 may become unnecessarily long and obstructive, or the cord length may become insufficient. Be prevented. In particular, in the case of a work vehicle such as a forklift, it is possible to prevent an unnecessarily long cord from being caught in something and causing an accident or the like.

After connecting the first connection unit 400 to the camera 210, the second connection unit 410 is then connected to the connection unit 300 of the recording device 30. After connecting the second connection portion 410 to the recording device 30, the sensor unit 50 is then attached to the forklift 110 around the seat 112. The sensor unit 50 may be attached near a place that becomes the center of rotation when the rear wheels are steered with the front wheels of the forklift 110 stopped. In this embodiment, it is attached to the lower part of the sheet 112. By attaching it to the lower part of the seat 112, the recording of the rotational movement of the forklift 110 and the driver's feeling due to the rotation of the forklift 110 can be made close to each other. When the sensor unit is attached, the attachment is completed by connecting the power supply to the recording device 30.

Next, a reproduction screen when the photographed image photographed by the camera unit 20 attached to the forklift 110 is reproduced by a personal computer or the like will be described with reference to FIG.

On the left side of the file list screen 60, that is, on the upper left 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 displayed. For example, when images taken by a plurality of cameras are recorded on the image screen 62, the images taken by the respective cameras can be projected at the same time. For example, when shooting with four cameras, four screens can be projected at the same time. 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.

Further, on the video screen, by performing a predetermined process (for example, right-clicking with the cursor on the video screen 62), vertical flipping, horizontal flipping, XX degree rotation, etc. can be performed. .. By performing this operation, even if the captured image is tilted or inverted depending on the orientation of the camera, the image can be returned to the normally visible state. 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 played back.

Below the video screen 62, an operating state screen 63 of the photographing target (forklift 110 in FIG. 12) detected by the acceleration sensor and the gyro sensor is arranged. The operation of the forklift 110 is displayed on the operation state screen 63 by numerical values and graphs.
