[0003] [Patent Document 1] JP 2019-139333 A Summary of the Invention [Problem to be solved by the invention]

[0004] For example, a forward driving direction drive recorder may be disposed in an upper area of ​​a windshield for legal reasons or to avoid interfering with the driver's field of vision while driving. In this case, it may be difficult for a person inside the vehicle (e.g., the driver) to see the information displayed on the display unit. On the other hand, for example, from the driver of a rear vehicle, the display unit may be positioned almost directly opposite the display surface. This may cause problems such as the driver of the rear vehicle seeing the information displayed on the display surface, or causing a distraction to the driver of the rear vehicle, which may interfere with driving. Therefore, there is a demand for a balance between ease of viewing the display content for people inside the vehicle and difficulty of viewing the display content for people outside the vehicle.

[0005] The purpose of the present invention is not limited to this, and the applicant intends to obtain rights for configurations that aim to obtain effects from parts of the configurations disclosed in this specification and drawings, etc., through divisional applications, amendments, etc. For example, this specification discloses a problem in which the part described as "can be" in this specification is read as "the problem is to be." The problems are described as independent, and the applicant intends to obtain rights for the configurations for solving these problems alone through divisional applications, amendments, etc. Even if the problem is implicitly understood from the description in the specification, the applicant intends to include part of the configurations described in this specification in the scope of the patent claim by amendment or divisional application. Problems that combine these independent problems are also disclosed. [Means for solving the problem]

[0006] (1) An in-vehicle device is provided that includes a camera and a display unit having a display surface, and when the camera is pointed in a first direction capable of capturing an image of an area outside the vehicle, the display surface faces a second direction in which a specified riding area inside the vehicle is located.

[0007] In this way, when the camera is directed in a first direction in which it can capture an image of an area outside the vehicle, the display surface necessarily faces in a second direction in which a specific boarding area is located inside the vehicle, making it possible to make the display content on the display surface easy for people in that boarding area to see, and difficult for people outside the vehicle to see. Therefore, it is possible to achieve both ease of viewing the display content for people inside the vehicle and difficulty of viewing the display content for people outside the vehicle.

[0008] (2) The first direction and the second direction may be non-parallel to each other.

[0009] In this way, even if the direction in which the shooting area outside the vehicle is located as seen from the camera and the direction in which a specific boarding area is located inside the vehicle as seen from the display surface are non-parallel, the content displayed on the display surface can be easily seen by people in that boarding area.

[0010] (3) When the photographing area exists in the traveling direction of the vehicle, the second direction may be inclined at a predetermined angle with respect to a direction opposite to the traveling direction of the vehicle.

[0011] In this way, when photographing the shooting area in the direction of travel of the vehicle, even if there is no specified boarding area on the opposite side, the display content can be easily viewed from that boarding area, and the display content can be made difficult to view from the opposite direction of travel of the vehicle, where there may be a vehicle behind.

[0012] (4) The second direction may be a direction rotated by the predetermined angle in one direction in a vehicle width direction of the vehicle from the reverse direction.

[0013] In this way, the display surface faces a direction rotated by a predetermined angle in one direction in the vehicle width direction from the opposite direction to the traveling direction of the vehicle, so that the display contents can be easily viewed from the riding area, and the display contents can be made difficult to view from the opposite direction of the traveling direction of the vehicle where a rear vehicle may be present. For example, even if the in-vehicle device is disposed near the center in the vehicle width direction on the windshield side of the vehicle, the display contents on the display surface can be easily viewed by a person sitting in the driver's seat or the passenger seat.

[0014] (5) The second direction may be a direction rotated downward from the reverse direction by the predetermined angle.

[0015] In this way, even if the eyes of a person in the riding area are located below the display surface, the display content can be seen, and the display content can be made difficult to see from the opposite direction of the vehicle's traveling direction, where a rear vehicle may be present. For example, when the in-vehicle device is disposed in the area on the windshield side of the vehicle, the display content on the display surface can be made easy to see for a person sitting in the driver's seat or the passenger seat.

[0016] (6) The passenger area may be an area where the driver's seat or passenger seat of the vehicle is located.

[0017] In this way, a person in the driver's seat or the passenger seat can easily view the contents displayed on the display screen without having to stand up or take a position that requires them to peer at the display screen.

[0018] (7) The viewing angle of the display surface may be set so that the content displayed on the display surface is visible from the boarding area but is more difficult to see from the opposite direction of the vehicle's travel.

[0019] In this way, when the viewing angle of the display surface is limited, the display content can be made difficult to see from the opposite direction of travel of the vehicle, where there may be a vehicle behind, while not impeding the visibility of the display content by people in a specified riding area.

[0020] (8) When the display device is disposed on a side of a rearview mirror of the vehicle in a traveling direction of the vehicle, the second direction may be a direction in which the display surface does not face the rearview mirror.

[0021] In this way, when the in-vehicle device is placed behind the rearview mirror to make its presence less noticeable, the display contents on the display surface can be unobstructed from a specified passenger area, and from the opposite direction of the vehicle's travel direction, where there may be a vehicle behind, the display surface is hidden by the rearview mirror, making it difficult to see the display contents on the display surface.

[0022] (9) The display surface may be a first display surface facing a second direction in which a first boarding area in the vehicle is located, and the display unit may further have a second display surface facing a third direction in which a second boarding area in the vehicle is located.

[0023] In this way, both the person in the first passenger area and the person in the second passenger area can see the display content on the display surface. For example, the display content can be easily seen by both the person in the driver's seat and the person in the passenger seat.

[0024] (10) The electronic device may have a case in which the camera and the display unit are provided, and the camera lens and the display surface may be fixedly provided to the case.

[0025] In this way, the relationship between the direction in which the camera lens faces and the direction in which the display surface faces is fixed, so that by adjusting the direction in which the camera lens faces, the direction in which the display surface faces can be set to a direction in which the display content can be easily viewed from a specified riding area, making it easy to adjust the position and attitude of the in-vehicle equipment.

[0026] (11) It is preferable that the device has an operation part facing the second direction.

[0027] In this manner, the operating unit faces the second direction, making it easier for people in a specified boarding area to view the display content on the display surface and to operate the operating unit.

[0028] (12) It is preferable to have a second camera capable of photographing the second direction.

[0029] In this way, since the second camera can capture an image in the second direction, it is possible to easily capture an image of a person viewing the display content on the display surface or the surrounding area from the front side.

[0030] (13) The display unit may display disaster information related to the disaster.

[0031] In this way, disaster-related information, which is one type of information of high importance that should be notified to people inside the vehicle, can be made easily recognizable to people in a specified passenger area.

[0032] (14) It is preferable that the image captured by the camera is recorded by a drive recorder.

[0033] In this way, it is possible to achieve both ease of viewing of the display content for people inside the vehicle and difficulty of viewing of the display content for people outside the vehicle.

[0034] (15) There is provided an imaging device comprising a camera and a display unit having a display surface, wherein when the lens of the camera is pointed in a first direction, the display surface faces a second direction that has a component in the opposite direction to the first direction and is non-parallel to the first direction, and the angle between the first direction and the second direction is fixed.

[0035] In this way, when the camera lens is pointed in a first direction, it necessarily faces a second direction which has a component in the opposite direction to the first direction and is non-parallel to the first direction. Therefore, while photographing the desired direction, the display content on the display surface can be easily viewed from the second direction, and the display content can be difficult to view from the opposite side of the lens.

[0036] The above-mentioned inventions (1) to (15) can be arbitrarily combined. For example, the invention shown in (1) may be combined with at least a portion of the configuration of at least one of the inventions from (2) onward. In particular, the invention shown in (1) may be combined with at least a portion of the configuration of at least one of the inventions from (2) onward. The applicant intends to obtain patent rights, design rights, etc. for those including these configurations by filing amendments, divisional applications, or applications for conversion to design registration applications. Effect of the Invention

[0037] According to the present invention, for example, at least one of the following effects can be achieved: It is possible to achieve both ease of viewing of the display content for people inside the vehicle and difficulty of viewing the display content for people outside the vehicle. For example, it is possible to make the display content of the display unit easy for the driver to view, and difficult for the driver of a vehicle behind to view the display content.

[0038] The effect of the invention of the present application is not limited to this, and the effect achieved from the configuration disclosed in the specification and drawings, etc. is also disclosed, and there is an intention to obtain rights to the configuration achieving said effect through divisional application, amendment, etc. For example, in this specification, the part that states "can..." is a description that clearly indicates the effect achieved, and there are parts that show the effect even without the description "can...". Also, there are effects that can be understood from the configuration even without such a description. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0040] Hereinafter, embodiments of the present invention will be described with reference to the drawings. These drawings are used to explain technical features that the present invention can employ. The configurations and shapes of the devices described are merely illustrative examples, and the present invention should not be interpreted as being limited thereto. Various changes, modifications, and improvements can be made based on the knowledge of those skilled in the art without departing from the scope of the present invention.

[0041] [Background of the idea] 20 is a diagram showing the external configuration of a drive recorder 90 and an example of its arrangement. The drive recorder 90 is a drive recorder according to a conventional configuration, and is arranged to capture the traveling direction of the vehicle. In the drive recorder 90, the camera lens and the display surface are back-to-back and face in opposite directions. In this example, the direction of the optical axis of the lens and the normal direction of the display surface are both horizontal or nearly horizontal.

[0042] The drive recorder 90 may be placed in an upper area of ​​the windshield for legal reasons or to avoid interfering with the driver's view while driving. In addition, one of the best positions for mounting the drive recorder is behind the rear-view mirror. In this way, the drive recorder 90 does not block the driver's view in the direction of travel, and the drive recorder 90 is difficult to see from people inside the vehicle, which may be aesthetically desirable. For this reason, users of the drive recorder 90 have a positive motivation to place it behind the rear-view mirror. However, if the drive recorder 90 is placed in this way, the display unit provided on the drive recorder 90 is hidden behind the rear-view mirror as shown in Figures 20(a) to 20(c). It becomes difficult for people inside the vehicle, such as the driver, to see the display content of the display unit. In addition, even if the drive recorder 90 is not placed behind the rear-view mirror, the drive recorder 90 is located relatively high up, so when the driver wants to see the display content, he or she needs to take a posture that puts a strain on the driver, such as looking up diagonally upward.

[0043] For example, in a sports car, the windshield may be inclined at a steep angle, and in this case, if the upper portion of the windshield is located directly above the driver, the above problem becomes more noticeable.

[0044] On the other hand, for example, from the driver of the rear vehicle, the display surface of the display unit of the drive recorder may be in a positional relationship almost directly facing the driver of the rear vehicle. Therefore, the information displayed on the display surface may be visible to the driver of the rear vehicle. In addition, the driver of the rear vehicle may be concerned about the display content of the display unit and may focus on it or feel it is dazzling. These may be a cause of distraction for the driver of the rear vehicle and may interfere with the driving.

[0045] For the reasons stated above, the inventors of the present application believe that there is a need for a drive recorder that can simultaneously make the displayed content easy to see for people inside the vehicle, and difficult to see for people outside the vehicle.

[0046] [First embodiment of the drive recorder] 1 to 8 and 19 show a first embodiment of a drive recorder 10. The drive recorder 10 is an example of an in-vehicle device and an image capturing device. The drive recorder 10 of this embodiment has a flat, upright main body case 13, in which various circuit boards and devices are mounted. The main body case 13 is attached and fixed to, for example, a windshield 2 of a vehicle, which is an example of an attachment portion, via a bracket 18, which is an example of an attachment member. The vehicle may be, for example, a private car or a commercial car, and the vehicle types may be passenger cars, buses, trucks, special vehicles such as forklifts, etc.

[0047] The main body case 13 is constructed by connecting a first case 14 and a second case 15 which are divided into two parts, front and rear. The first case 14 and the second case 15 are box-shaped with their opposing faces open, and are connected by a predetermined connecting means with their tip faces butted against each other. The connecting means may, for example, be a protrusion provided on one of the first case 14 and the second case 15, and a recess provided on the other case that links with the protrusion, and the protrusion and the recess may be fitted together, and it is particularly preferable to fix them using fastening means such as bolts, nuts, and screws.

[0048] Both the first case 14 and the second case 15 are long horizontally, and when the drive recorder 10 is installed in the vehicle, the first case 14 is located in the direction of travel of the vehicle and faces the windshield 2. When the drive recorder 10 is installed in the vehicle, the second case 15 is located on the rear side of the vehicle and faces the inside of the vehicle.

[0049] In this embodiment, the vertical direction is the up-down direction of the vehicle, and the direction perpendicular to the vertical direction is the horizontal direction. Therefore, any direction within 360 degrees within a horizontal plane perpendicular to the vertical direction is also the horizontal direction.

[0050] The surface 14a of the first case 14 is a flat surface, and the camera 17 is disposed near the center of the longitudinal direction of the left and right sides (for example, the vehicle width direction when placed on the vehicle) and slightly above the vertical direction. The camera 17 has an imaging element (for example, a CMOS or CCD) and a lens 17a (not shown). The camera 17 is mounted in the main body case 13 so that the direction of the optical axis of the lens 17a, which is the direction of the camera 17, is parallel to the normal direction of the surface 14a. When the surface 14a of the first case 14 is oriented horizontally in the traveling direction of the vehicle, for example, the lens 17a of the camera 17 faces the traveling direction (forward) of the vehicle. The camera 17 photographs an area (hereinafter referred to as the "photographing area") that exists in the traveling direction of the vehicle. The photographing area is an area outside the vehicle. The direction in which the camera 17 (lens 17a) faces is an example of the first direction.

[0051] The first case 14 is a box-like shape that is deeper than the second case 15, and has a top surface 14b that has a predetermined length in the front-to-rear direction of the vehicle. The top surface 14b is provided with an insertion port 28 for a pin jack to which the plug of the power cable 27 is attached, and an insertion port 30 for a female connector to which the min USB connector terminal of the communication cable 29 is attached.

[0052] The top surface 14b is provided with a joint rail 16. The joint rail 16 extends in the front-rear direction, and two rails, one on the left and one on the right, are provided at a predetermined distance. A bracket 18 is detachably attached between the two joint rails 16.

[0053] Bracket 18 has a flat mounting portion 22 having an attachment surface to be attached to windshield 2, a pair of ball studs 23 formed to stand up from mounting portion 22, a socket portion 24 into which the ball portion at the tip of ball stud 23 is attached, a nut 26 that is removably attached around socket portion 24, and a base member 25 that is formed as a pair with socket portion 24.

[0054] Socket portion 24 has notches 24a that extend from the tip side toward base member 25 at predetermined angular intervals in the circumferential direction, and the small pieces between adjacent notches 24a are flexible. In addition, a male thread is provided on the outer periphery of socket portion 24, and a nut 26 that fits onto the male thread is attached to the outer periphery of socket portion 24. As a result, before nut 26 is tightened with the ball portion of ball stud 23 fitted into socket portion 24, socket portion 24 rotates in a desired direction along the circumferential surface of the ball portion, making it possible to change the attitude and position of mounting portion 22, and when nut 26 is tightened, the angular position is fixed.

[0055] The bracket 18 is detachably attached by sliding the base member 25 between the pair of joint rails 16. Then, an adhesive member 21 such as a double-sided adhesive tape is affixed to the mounting portion 22, and the bracket 18 is affixed to the windshield 2 of the vehicle via the adhesive member 21.

[0056] In this embodiment, the bracket 18 is fixed by attaching the mounting portion 22 to the vicinity of the center in the width direction on the upper side of the windshield via the adhesive member 21. As a result, as shown in FIG. 4, for example, the drive recorder 10 to which the bracket 18 is attached is located on the traveling direction side of the rear-view mirror 31 (hereinafter, sometimes referred to as the rear side of the rear-view mirror 31), and when a person in the vehicle faces the rear-view mirror 31, almost the entire inside of the main body case 13 of the drive recorder 10 is hidden by the rear-view mirror 31. In this way, the drive recorder 10 does not block the driver's view in the traveling direction and the drive recorder 10 is difficult to see from people inside the vehicle, which may be desirable from the viewpoint of aesthetics.

[0057] The second case 15 is a box-shaped body with a shallower bottom than the first case 14. The surface 15a opposite to the opening surface of the second case 15 is divided into two parts, left and right, in the longitudinal direction. When looking at the surface 15a from inside the vehicle, the first region R1 on the left side is a flat surface parallel to the surface 14a of the first case 14, and the second region R2 on the right side is an inclined surface approaching the surface 14a of the first case 14 as it approaches the end. Since the first region R1 is parallel to the surface 14a of the first case 14, for example, the orientation of the camera 17 (lens 17a) can be aligned based on the first region R1. Since the lens 17a is exposed to the outside of the first case 14, a person can adjust the position and attitude of the drive recorder 10 while looking at the lens 17a so that the desired shooting area can be shot.

[0058] Such alignment can be performed, for example, by attaching bracket 18 to the windshield and loosening nut 26 with bracket 18 attached to main body case 13. Then, the orientation of first region R1, and therefore the orientation of lens 17a of camera 17, is set to a desired orientation, for example, the traveling direction of the vehicle, and nut 26 is tightened in this state, whereby lens 17a of camera 17 is fixedly provided.

[0059] In this embodiment, the first region R1 and the second region R2 on the surface 15a of the second case 15 face in different directions. That is, since the first region R1 is a plane parallel to the surface 14a of the first case 14, it faces the opposite direction on the same line as the direction of the camera 17. Therefore, for example, when the drive recorder 10 is attached to a vehicle, if the optical axis of the camera 17 is arranged to face the traveling direction of the vehicle, the surface 15a of the first region R1 faces the opposite direction of the traveling direction of the vehicle. If the traveling direction of the vehicle is the horizontal direction, the opposite direction to the traveling direction of the vehicle is also the horizontal direction. In this case, the opposite direction to the traveling direction of the vehicle can be said to be directly behind the vehicle. Therefore, for example, if the first region R1 is used as a reference plane and the first region R1 is arranged to face the traveling direction of the vehicle, the lens 17a of the camera 17 can be directed to the traveling direction of the vehicle.

[0060] The opening of the second case 15 has its long side formed parallel to the first region R1 and the second region R2 of the surface 15a, and the side of the long side facing the first region R1 in the longitudinal direction forms a straight side 15d parallel to the surface 14a of the first case 14, and the side facing the second region R2 forms an inclined side 15e.

[0061] The opening surface of the first case 14 is aligned with the opening surface of the second case 15. The first case 14 has a uniform depth from one side in the longitudinal direction of the first region R1 to a predetermined position beyond the center, and gradually becomes shallower on the other side. Accordingly, the opening surface of the first case 14 has a straight side 14d parallel to the surface 14a on one side in the longitudinal direction of the long side, and an inclined side 14e on the other side. The inclination angle of the inclined side 14e is set to be equal to that of the inclined side 15e of the second case 15.

[0062] In this embodiment, the first region R1 side of the second region R2 of the surface 15a of the second case 15 is shaped to protrude outward from the first region R1. The display unit 19 (display surface 19a) is provided in the second region R2. The display contents of the display surface 19a include display elements exemplified by characters, images (for example, stored by the function of the drive recorder), and icons. The display surface 19a is a rectangular display area, but may be an area of ​​other shape. The display surface 19a faces in a second diagonal horizontal direction. In this embodiment, the display surface 19a faces in the same horizontal direction as the first region R1, which is the same as the orientation of the second region R2. In this embodiment, the direction in which the display surface 19a faces is the normal direction of the display surface 19a. The direction in which the display surface 19a faces is non-parallel to the direction in which the camera 17 (lens 17a) faces. The direction in which the display unit 19 (display surface 19a) faces is an example of the second direction. In this embodiment, the display surface 19a faces a direction rotated by a predetermined angle from the opposite direction of the vehicle's traveling direction to one side in the vehicle width direction. Here, the one side in the vehicle width direction is the side where the driver's seat is located. The predetermined angle is, for example, 45 degrees, but is not limited to this. The driver's seat is a seat provided in the boarding area of ​​the vehicle. The boarding area is an area in which a person in the vehicle is or may be present. When the vehicle is traveling, the driver sits in the driver's seat.

[0063] Moreover, the display unit 19 is composed of, for example, a liquid crystal display (LCD). The display surface 19a of the display unit 19 has a predetermined viewing angle. Therefore, when the display surface 19a is viewed obliquely outside the viewing angle, the display contents cannot be seen or are barely visible. In this embodiment, the second region R2 is disposed on the right side when viewing the surface 15a from inside the vehicle, so that in a right-hand drive vehicle, it is located on the driver's seat side, and the display surface 19a is disposed so as to face the driver's seat side at an angle to the right with respect to the rear side of the vehicle. Therefore, the driver sitting in the driver's seat will, for example, be almost directly facing the display surface 19a. The display surface 19a may be provided with, for example, a viewing angle limiting sheet as a viewing angle limiting member that limits the viewing angle.

[0064] As described above, the lens 17a of the camera 17 and the display surface 19a of the display unit 19 are fixedly provided with respect to the case of the drive recorder 10. In this way, by adjusting the direction in which the lens 17a of the camera 17 faces, the direction in which the display surface 19a faces is set to a direction in which the display content is easily visible from the driver's seat side, so that it is possible to easily adjust the position and attitude of the drive recorder 10.

[0065] Also, the driver's seat where the driver sits is located at a position slightly shifted in the vehicle width direction from the opposite direction of the driving direction of the vehicle of the drive recorder 10. Even in such a case, the driver can see the display surface 19a within the range of a viewing angle from the front or almost the front, and can easily view the display contents of the display surface 19a without, for example, standing up or taking a posture such as looking into the display surface. In particular, when the drive recorder 10 is located behind the rearview mirror 31, in other words, on the windshield side of the vehicle and near the center in the vehicle width direction, the display contents of the display surface can be easily viewed by the person sitting in the driver's seat. On the other hand, from the opposite direction of the driving direction of the vehicle where a rear vehicle may exist, the display contents are viewed from a direction outside the viewing angle, making it difficult to view the display contents.

[0066] In addition, when the drive recorder 10 is arranged behind the rear-view mirror 31 (the side in the traveling direction of the vehicle), the display surface 19a is configured to face in a direction that does not face the rear-view mirror 31. In this way, the drive recorder 10 is arranged behind the rear-view mirror 31, making its presence less noticeable, and it is possible to prevent the display contents of the display surface 19a from being visually recognized from the driver's seat side. Furthermore, since the display surface 19a is hidden by the rear-view mirror 31 from the opposite direction of the traveling direction of the vehicle, where a rear vehicle may be present, it is possible to make the display contents of the display surface 19a less visible.

[0067] Even if the main body case 13 of the drive recorder 10 is shifted, for example, in the front-rear or left-right direction, rather than being arranged so as to be hidden behind the rear-view mirror 31, the display surface 19a faces the driver's seat at an angle to the right and does not face directly behind the vehicle, so that the display contents are difficult to see from outside the vehicle. In particular, from the opposite direction of the traveling direction of the vehicle, where a rear vehicle may be present, the display is not only outside the viewing angle but also far away, so that the driver of the rear vehicle will not stare at it, it is not dazzling, it is not distracting, and it is possible to suppress interference with driving.

[0068] The installation of the drive recorder 10 can also be described as follows. If the display surface 19a is oriented in a direction that is easy to see from the driver's seat, the camera 17 can naturally be made to face an appropriate direction, such as the direction of travel of the vehicle. For example, even if the case of the drive recorder 10 is located behind the rearview mirror 31 and is hidden by the rearview mirror 31, making it difficult to adjust the orientation of the camera 17, the orientation of the camera 17 can be adjusted based on the orientation of the display surface 19a.

[0069] [Second embodiment of the drive recorder] This form of drive recorder is based on the knowledge that the mounting location is in the upper area of ​​the windshield, the lens is in the direction of vehicle travel, and the positional relationship is roughly fixed, with the lens being located diagonally below the driver's seat when viewed from the position of the drive recorder.

[0070] 9 to 13 show a second embodiment of the drive recorder 40. In this embodiment, a main body case 43 in which the camera 41, the display unit 42, etc. are mounted is cylindrical. A bracket 45, which is an example of an attachment member, is attached to one end of the cylindrical main body case 43 in the axial direction. The bracket 45 includes, for example, a ring-shaped portion 45a that faces the outer circumferential surface of the main body case 43 and has a rotatable arc surface on its inner circumferential surface, a connecting portion 45b that is integrally formed on the outer circumferential surface of the ring-shaped portion 45a, and a plate-shaped attachment portion 45c that is integrally formed at the tip of the connecting portion 45b.

[0071] In this embodiment, the outer diameter of one end of the main body case 43 is reduced, and the ring-shaped portion 45a is attached to the reduced portion. As a result, a wall 43d is formed on the axially inner side of the portion of the one end of the main body case 43 with the reduced outer diameter, and one axial surface of the ring-shaped portion 45a attached to the portion abuts against the wall 43d. Then, with the bracket 45 attached to the one end of the main body case 43 in this manner, the fixing member 46 is attached to one end of the main body case 43, and both axial side surfaces of the bracket 45 are sandwiched and fixed between the fixing member 46 and the wall 43d of the main body case 43. The main body case 43 and the ring-shaped portion 45a are configured to be relatively rotatable, and are configured to be fixed at an appropriate angular position. Fixing at such a predetermined angle position can be achieved by, for example, providing a female threaded portion on the inner surface of fixing member 46, forming a male threaded portion on the outer peripheral surface of one end side of main body case 43, engaging these female threaded portion with the male threaded portion, and tightening the screw to narrow the distance between the tip of fixing member 46 and wall 43d of main body case 43, thereby sandwiching and fixing ring-shaped portion 45a, or by providing a recess and projection that can be fitted into the inner surface of ring-shaped portion 45a and the outer peripheral surface of the part of one end side of main body case 43, so that the angle is fixed at the position where the recess and projection are fitted, and when force is applied in the rotational direction, the recess and projection are released to allow rotation.Various configurations can be adopted.

[0072] Then, an adhesive member 47 such as double-sided tape is affixed to the surface of the mounting portion 45c on the side not connected to the connecting portion 45b, and the bracket 45 is attached to a predetermined position on the windshield 2 using the adhesive member 47. As a result, the main body case 43 supported by the bracket 45 is suspended and fixed to the predetermined position on the windshield 2.

[0073] Inside the cylindrical main body case 43, for example, a first circuit board 51 and a second circuit board 52 connected by a connector 53 are arranged in a front-to-back overlapping posture. The first circuit board 51 includes, for example, a CPU, a memory, an image pickup element of the camera 41, a control unit of the display unit 42, and the like, and is arranged so that the lens 41a of the camera 41 is exposed on the outer surface of the main body case 43. The first circuit board 51 is connected to the display unit 42 via a connection unit 48. The connection unit 48 is a wiring unit formed of, for example, a flexible printed circuit board (FPC), and supplies various signals (for example, scanning line driving signals and data line driving signals) for driving the display unit 42 and signals (video signals) that define the display contents. In this embodiment, the lens 41a is directed in the traveling direction of the vehicle, so that the camera 41 captures an image capturing area that exists in the traveling direction of the vehicle (an example of a first direction). The image capturing area is an area outside the vehicle. Note that the direction in which the camera 41 (lens 41a) faces is an example of the first direction. Since the lens 41a is exposed to the outside of the main body case 43, a person can adjust the position and attitude of the drive recorder 40 while looking at the lens 41a so as to be able to capture a desired capture area.

[0074] The second circuit board 52 has, for example, a power supply control circuit and is equipped with, for example, an electric double layer capacitor 54, an SD card connector 55, an operation switch 56, etc. The operation switch 56 and the SD card connector 55 are preferably arranged so as to be exposed on the side surface 43a, etc. of the main body case 43, and can be operated from the side surface 43a. In this embodiment, the operation switch 56, etc. is provided on the side surface 43a on the right side as seen by the driver, etc., who is a person inside the vehicle, in this example, the side surface 43a on the mounting side of the bracket 45. This allows the operation switch 56, etc. to be arranged on the driver's side, improving operability for the driver.

[0075] A flat surface 43b is provided at a predetermined position on the circumferential surface of the main body case 43. One end of the flat surface 43b in the longitudinal direction reaches a side surface 43c of the main body case 43 on the side where the bracket 45 is not attached. The display surface 42a of the display unit 42 is arranged on the flat surface 43b. The display surface 42a is a rectangular display area that is long in the axial direction of the main body case 43, but may be an area of ​​another shape. The direction in which the display surface 42a of the display unit 42 faces is non-parallel to the direction in which the camera 41 (lens 41a) faces. The display unit 42 is composed of, for example, an LCD. The camera 41 and the display unit 42 are fixedly provided on the main body case 43 so that the direction of the display surface 42a of the display unit 42, i.e., the normal direction L1 of the display surface 42a, and the optical axis L2 of the lens 41a of the camera 41 intersect at a predetermined angle. Therefore, for example, when main body case 43 is rotated around an axis while attached to bracket 45, the orientation of camera 41 is swung up and down, and rotates while maintaining the angle between display surface 42a of display unit 42 and camera 41 (lens 41a).

[0076] In this embodiment, the display surface 42a is rotated downward by a predetermined angle from the opposite direction to the traveling direction of the vehicle. When the lens 41a is directed toward the traveling direction of the vehicle, the display surface 42a faces diagonally downward (an example of the second direction) (see FIG. 9, etc.). In this embodiment, the direction in which the display surface 42a faces is the normal direction of the display surface 42a. The predetermined angle is, for example, 45 degrees, but is not limited to this.

[0077] The appearance of the drive recorder 40 when viewed from each of the directions (A), (B), (C), and (D) in Fig. 11 is as shown in Fig. 12(a), (b), (c), and (d), respectively. As shown in Fig. 12(d), when the camera 41 is, for example, horizontally facing the traveling direction of the vehicle, as is clear from Fig. 13, when the driver sitting in the driver's seat directs his or her gaze diagonally upward (see Fig. 12(B)), he or she faces the display surface 42a directly and can view the screen at a shallow angle, making the displayed content easy to see.

[0078] As described above, the problems of the conventional configuration can be solved simply by rotating display surface 42a downward by a predetermined angle with respect to the direction of the optical axis of lens 41a of camera 41. Furthermore, since cylindrical main body case 43 is suitable for a structure in which display unit 42 (e.g., a liquid crystal display) is angled, and connecting portion 48 connecting display unit 42 and first circuit board 51 is formed flexibly, no unreasonable structure is required. Furthermore, if display unit 42 is a relatively inexpensive liquid crystal display, the viewing angle of such a liquid crystal display is relatively narrow, and therefore the effect of improving the apparent image quality can be expected.

[0079] In addition, the lens 41a of the camera 41 and the display surface 42a of the display unit 42 are fixedly provided to the main body case 43 of the drive recorder 40. In this way, by adjusting the direction in which the lens 41a of the camera 41 faces, the direction in which the display surface 42a faces is set to a direction in which the display contents are easily visible from below, so that the position and posture of the drive recorder 40 can be easily adjusted. Since the driver is sitting in the driver's seat, the driver (the driver's eyes) are present below the drive recorder 40. Therefore, the driver can view the display surface 42a within a range of viewing angles such as from the front, making it easier to view the display contents of the display surface 42a. (See viewpoint (B) in FIG. 13). For example, a viewing angle control sheet may be provided on the display surface 42a as a viewing angle control member that controls to narrow the viewing angle.

[0080] On the other hand, for a person in the opposite direction of the traveling direction of a vehicle where a rear vehicle may exist, for example, a person riding in the rear vehicle, the display surface 42a is viewed from directly behind, and is viewed from a direction outside the viewing angle of the display surface 42a (see (A) in FIG. 11). Therefore, it is possible to make the display content difficult to see from outside the vehicle. In particular, from the opposite direction of the traveling direction of a vehicle where a rear vehicle may exist, the display surface 42a is not only in a direction outside the viewing angle, but also at a distance, so that the driver of the rear vehicle, etc., will not stare at the display surface 42a, it will not be dazzling, and it will not be distracting, and it is possible to suppress the display surface 42a from interfering with driving.

[0081] Furthermore, when the drive recorder 40 having such a configuration is arranged on the rear side (the side in the traveling direction of the vehicle) of the rearview mirror 31 as in the first embodiment, as shown in, for example, Fig. 13, the display surface 42a faces downward in the opposite direction to the traveling direction of the vehicle. In this way, the drive recorder 40 is arranged behind the rearview mirror 31 and its presence is not noticeable. Furthermore, as shown in viewpoint (A) in Fig. 12, the display surface 42a is hidden by the rearview mirror 31 from the opposite direction to the traveling direction of the vehicle where a rear vehicle may be present, so that the display content of the display surface 42a can be made difficult to see.

[0082] Furthermore, the display surface 42a faces in a direction rotated downward by a predetermined angle from the opposite direction of the vehicle's travel direction, and if the angle is set to 45 degrees assuming that a tall person's line of sight is horizontal to the drive recorder 40 and that the windshield 2 is tilted so that the drive recorder 40 is located near overhead, for example, there will be a margin of 15 degrees even if the viewing angle of the display surface 42a is 60 degrees up and down. This is good because the drive recorder 40 can be seen even when the windshield 2 is tilted and the drive recorder 40 is located near overhead, for example.

[0083] The installation of the drive recorder 40 can also be described as follows. If the display surface 42a is oriented in a direction that is easy to see from the driver's seat, the camera 41 can naturally be made to face an appropriate direction, such as the direction of travel of the vehicle. For example, even if the case of the drive recorder 40 is located behind the rearview mirror 31 and is hidden by the rearview mirror 31, making it difficult to adjust the orientation of the camera 41, the orientation of the camera 17 can be adjusted based on the orientation of the display surface 42a.

[0084] [Various modified examples of drive recorders] The direction in which the display surface of the display unit faces may be rotated by a predetermined angle in one direction of the vehicle width direction and downward by a predetermined angle with respect to the direction opposite to the traveling direction of the vehicle. For example, in the drive recorder 40 having the cylindrical main body case 43 as in the second embodiment, the display surface 42a of the display unit 42 may be inclined so as to face diagonally, for example, diagonally rightward, with respect to the direction opposite to the traveling direction of the vehicle so as to face the driver's seat side. For example, in FIG. 14, the flat surface portion 43b provided on the main body case 43 may be inclined so that the area on the driver's seat side protrudes in the direction opposite to the traveling direction of the vehicle and the area on the passenger seat side recedes. In this way, it is expected that the display contents of the display surface will be more easily visible to the driver and the display contents of the display surface will be less easily visible from the rear vehicle, etc.

[0085] Also, as shown in FIG. 15, for example, the display unit 42 may have two display surfaces 42a, 42b (examples of the first display surface and the second display surface) arranged on the left and right, with one of the two display surfaces 42a facing an oblique direction (an example of the second direction) toward the driver's seat side (an example of the first riding area) of a right-hand drive vehicle, and the other display surface 42b facing an oblique direction (an example of the third direction) toward the passenger seat side (an example of the second riding area) of a right-hand drive vehicle. In the figure, for example, the portion between the two display surfaces 42a, 42b may be a flat surface portion 43b that protrudes most forward and inclines toward the left and right sides. The area where the passenger seat is arranged is an example of a riding area that is an area where a person in the vehicle exists or may exist.

[0086] In this way, the display contents can be seen by both the driver's seat and the passenger seat, and can be applied as is to left-hand drive vehicles. The contents displayed on the two display surfaces 42a, 42b may be the same or different. If the contents are different, appropriate information can be provided to each person.

[0087] In this case, the two display surfaces 42a, 42b may be configured with separate liquid crystal displays, or may be configured with a single member using a curved or bendable liquid crystal display, etc. As a display unit other than a liquid crystal display, for example, an organic EL display, electronic paper, etc. may be used.

[0088] Also, as shown in FIG. 16, it is preferable to provide an operation unit 57 around the display unit 42 (display surface 42a). The operation unit 57 faces the same direction as the display surface 42a. The operation unit 57 is provided on the same surface of the main body case 43 as the surface on which the display surface 42a is provided. The operation unit 57 is, for example, a push-type physical button, but may be a slide-type or other type physical button. The number of operation units 57 is three in the example of FIG. 16, but is not limited to this. In this way, in addition to making the display contents easy to see, it is preferable that the operation unit is easy to operate. Since the operation unit 57 faces the direction of the driver sitting in the driver's seat, for example, like the display surface 42a, the driver can easily confirm the position of the operation unit 57, and even if a plurality of operation units 57 are provided, it is easy to confirm the position of each operation unit 57 while sitting, and to operate the desired operation unit 57 from that position. For example, there are cases where the driver can operate the desired operation unit 57 while sitting in the driver's seat. In the illustrated example, the operation unit 57 is separately disposed outside the display surface 42a of the display unit 42, but for example, a touch sensor or a proximity sensor may be used as the operation unit and the operation unit may be disposed on top of the display surface 42a. In this way, it is preferable to dispose an output means for outputting information from an LED or other light-emitting unit, instead of an input means. Since the flat portion 43b on which the display surface 42a of the display unit 42 is provided faces the driver, etc., the light-emitting state of the light-emitting unit, etc., is easily visible.

[0089] Furthermore, as shown in FIG. 17, for example, the second camera 58 may be disposed around the display surface 42a. The second camera 58 is provided so as to be able to capture the direction in which the display surface 42a faces. The second camera 58 is provided at a position where the display surface 42a and the lens of the second camera 58 can be simultaneously viewed, such as the same surface of the main body case 43 on which the display surface 42a is provided. In this way, the second camera 58 can easily capture the person or surroundings sitting in the driver's seat and / or the passenger seat in the vehicle from the front side. Therefore, for example, by capturing the posture of the driver, the drive recorder is suitable for incorporating functions of a DMS (driver monitoring system) such as detection of driver drowsiness or driver's distraction. In addition, the second camera 58 may be a thermograph to measure and record the body temperature of the user such as the driver, so that the health condition can be managed.

[0090] In the above-described embodiment and modified examples, the shape of the main body case 43 is based on a cylindrical shape, but the shape is arbitrary, and various shapes such as a sphere, a hemisphere, or a rectangular parallelepiped may be used.

[0091] [Disaster warning function] The drive recorder in the above-mentioned embodiment and modified examples may have a disaster warning function. For example, the control unit of the drive recorder may have a means for acquiring disaster information and may control the display unit to display a warning based on the acquired disaster information on the display surface 19a or 42a. The disaster information is information related to a disaster. The disaster information may include information related to either or both of a disaster that has already occurred (e.g., earthquake, landslide, etc.) or a disaster that is expected to occur (e.g., weather-related disasters such as tornadoes and typhoons, etc.).

[0092] The means for acquiring disaster information may, for example, have a function for receiving disaster and crisis information (an example of disaster information) from Michibiki. In this way, it is advantageous because the GPS unit for acquiring location information can be used as well.

[0093] The control unit may then be configured not to issue a disaster information warning if the location of the acquired disaster / crisis information is far from the current location, but to issue a warning about disaster information, etc., if the location is within a set distance, for example.

[0094] The disaster information warning may be displayed on the display surface 19a or 42a. For example, if the drive recorder is positioned so that the display surface faces directly behind the vehicle, and is particularly hidden behind the rear-view mirror, the driver cannot see a predetermined notification screen displayed on the display surface to report a disaster. In contrast, in this embodiment, the display surface 19a or 42a faces the driver, etc., and even if the drive recorder 40 is located behind the rear-view mirror 31, the driver, etc. can easily see the display content. Therefore, when a notification screen is displayed on the display surface 19a or 42a to issue a warning based on disaster information, the driver, etc. can be appropriately informed of the warning. The driver can see and understand the display content, and therefore can take appropriate action in response to the warning.

[0095] Furthermore, the warning may be, for example, by displaying an icon 60 (an icon representing a tsunami in the illustrated example) on the display surface 19a or 42a in accordance with the content of the disaster or crisis (see FIG. 18, etc.). In this way, even if the display surface 19a or 42a is small, for example, the driver or the like can be appropriately notified of the occurrence of a disaster or crisis and its content.

[0096] Furthermore, the warning may be made by voice in addition to the display surface 19a or 42a. The warning may be changed according to the situation, such as the driving location and speed. For example, if an earthquake warning is issued while driving on an urban road at a certain speed or less, an icon corresponding to the earthquake is displayed on the display surface 19a or 42a and a voice message such as "Please park the car on the left side of a place that is considered safe" is output from the speaker. Furthermore, the content of the warning may be changed by user settings.

[0097] The control unit may also have a function to guide users to emergency evacuation shelters in the event of a disaster. In the case of a tsunami, the control unit may have a function to guide users to nearby safe locations above sea level, rather than to emergency evacuation shelters. In addition to announcing the location, the control unit may also have a function to provide route guidance.

[0098] Furthermore, when the control unit receives disaster information, it may display a "Confirm" button or the like on the display surface 19a or 42a, and after the user touches the screen, it may forcibly switch the screen on the display surface 19a or 42a to the earthquake disaster support mode and notify the user of the necessary information. It may also be configured so that the earthquake disaster support mode returns to the normal screen upon a specific user operation.

[0099] According to this embodiment, it is possible to make it easier for the driver and other people in the vehicle to recognize information related to a disaster that has occurred, which is one type of information of high importance that should be notified to people in the vehicle. Of course, information other than disaster information may be displayed on the display surface.

[0100] In the above embodiment, the visual recognition of the display surface 19a, 42a from the driver's seat side (driver), which is an example of the riding area, has been described, but the present invention can also be applied to the visual recognition of the display surface 19a, 42a from the passenger seat side (person sitting in the passenger seat). In this case, the display surface 19a, 42a only needs to face the passenger seat side. The same applies when applied to a left-hand drive vehicle. The vehicle may be various vehicles such as public transportation vehicles such as trains, monorails, and linear motor cars. This is because, if the vehicle is one in which people ride, there is a riding area that is an area where the driver, who is a person inside the vehicle, is present or may be present. The riding area may or may not have a seat. The present invention may also be applied to a drive recorder in which the mounting location of the drive recorder is not limited to the windshield, but is a location such as the ceiling, sun visor, or dashboard of the vehicle.

[0101] The in-vehicle device of the present invention may be any device other than a drive recorder as long as it has a camera and a display unit.

[0102] In light of the above-described embodiment and modified examples, the present invention can be understood as follows. The photographing device includes a camera and a display unit having a display surface, and when the camera is directed in a first direction, the display surface faces a second direction having a component in the opposite direction to the first direction and being non-parallel to the first direction, and the angle between the first direction and the second direction is fixed. Such a photographing device may be an in-vehicle device, a surveillance camera, or other photographing device. In this way, when the lens of the camera is directed in the first direction, it necessarily faces the second direction having a component in the opposite direction to the first direction and being non-parallel to the first direction, so that while photographing a desired direction, it is possible to easily view the display content on the display surface from the second direction and to make the display content difficult to view from the opposite side of the lens.

[0103] The scope of the present invention is not limited to the configurations explicitly described in the specification, but includes combinations of various aspects of the present invention disclosed in this specification. The configurations of the present invention that are to be patented are specified in the attached claims, but it is our intention to include configurations disclosed in this specification in the claims in the future, even if they are not currently specified in the claims.

[0104] The present invention is not limited to the configuration described in the above-mentioned embodiment. The components of each of the above-mentioned embodiments and modifications may be arbitrarily selected and combined. Any components of each of the embodiments and modifications may be arbitrarily combined with any components described in the means for solving the invention or any components that embody any components described in the means for solving the invention. We intend to acquire rights to these as well through amendments to this application or divisional applications. Even if there is a description such as "in the case of" or "when", this is not intended to describe a configuration that is limited to that case or time. We also disclose configurations that are not in these cases or times, and we intend to acquire rights. Furthermore, the parts described in order are not limited to this order. We also disclose configurations in which some parts are deleted or the order is changed, and we intend to acquire rights.

[0105] In addition, we intend to obtain rights to the overall design or partial design by converting to a design registration application. The drawings depict the entire device in solid lines, but they include not only the overall design but also partial designs claimed for a part of the device. For example, some parts of the device may be partial designs, and the drawings include some parts of the device as partial designs regardless of the parts. A part of the device may be a part of the device, or a part of that part. We intend to obtain rights to the overall design, as well as partial designs in which any part of the solid line part of the drawing is shown as a broken line part. In addition, the modules, parts, and components inside the device's casing, all of which are shown in the drawings, are subject to trade independently, and we intend to obtain rights to them by converting to a design registration application.
