The appendage 60 accommodates an electrical configuration for transmitting the video signal of the rear camera 63 to the recorder body 10 through the signal cable 40 in a casing 61 having a substantially rectangular parallelepiped shape that is thin in the front-rear direction. As shown in FIGS. 5A, 5B, and 6B, the attachment 60 is attached to the recorder main body 10 so that the upper surface is in contact with the lower surface of the recorder main body 10.

  FIG. 9 shows a configuration of the left side surface of the recorder main body 10 in a state where the signal cable 40 and the attachment 60 are detached from the recorder main body 10. FIG. 10A shows the configuration of the upper surface of the recorder body 10 in the same state.

  As can be understood from FIGS. 9 and 10A, the groove 18 for accommodating a part of the cable main body 41 is provided from the upper end to the lower end of the side surface of the recorder main body 10 along the vertical direction. The groove 18 forms a substantially semicircular space having a horizontal cross section parallel to the front, rear, left and right and having a diameter slightly larger than the diameter of the cable body 41. The signal cable 40 is accommodated in this substantially semicircular space. The above-described approximately semicircular space may be understood as a rounded approximately semirectangular space.

  The groove 18 further has a plurality of tightening portions 181 at positions separated in the vertical direction. The fastening portion 181 forms a space narrower than other portions of the groove 18 in the horizontal cross section. The cable body 41 of the signal cable 40 is covered with a film having elasticity, and the fastening portion 181 uses the elasticity of this film to sandwich the cable body 41 to such an extent that the film is slightly deformed. Thus, the cable body 41 is held more firmly than the other portions of the groove 18.

  FIG. 10B shows a configuration of the lower surface of the recorder main body 10 in a state where the signal cable 40 and the appendage 60 are detached from the recorder main body 10. As can be understood from FIG. 10B, the lower surface of the recorder main body 10 has two fitting holes 29 that function as engaging portions with the appendage 60.

  The fitting hole 29 has a configuration in which a first hole portion 291 and a second hole portion 293 having a shorter width in the front-rear direction than the first hole portion 291 communicate with each other. The first hole portion 291 is formed in a size that allows the fitting protrusion 67 provided in the attachment body 60 to be inserted, and the second hole portion 293 is smaller than the width of the head portion 671 of the fitting protrusion 67 in the front-rear direction. Formed.

  As shown in FIGS. 11, 12A, 12B, and 12C, the appendage 60 includes two fitting protrusions 67 that function as an engaging portion with the recorder main body 10 on the upper surface thereof. The fitting protrusion 67 includes a head 671 and a base 673 that supports the head 671.

  The base 673 includes a first base 674 and a second base 675 that is wider in the front-rear direction than the first base 674. The head 671 extends in a plate shape in the horizontal direction (front-rear and left-right directions) above the first base 674 and the second base 675. The first base portion 674 is provided so as to be disposed closer to the second hole portion 293 than the second base portion 675 when the fitting protrusion 67 is inserted into the fitting hole 29 of the recorder body 10.

  As can be understood from the shapes of the fitting holes 29 and the fitting protrusions 67, the appendix 60 has the user attaching the fitting protrusions 67 to the first holes 291 of the recorder body 10 and the first base 674 to the second. The attachment 60 is slid to the second hole 293 side along the lower surface of the recorder body 10 in a state of being inserted so as to face the hole 293 side, and is attached and fixed to the recorder body 10.

  When the appendage 60 is attached to the recorder main body 10, the head 671 of the fitting protrusion 67 is disposed inside the casing 11 of the recorder main body 10 and constitutes the periphery of the second hole 293 of the casing 11. Interfering with the part is prevented from moving downward. Further, the second base portion 675 of the fitting protrusion 67 interferes with the housing 11 at the boundary between the first hole portion 291 and the second hole portion 293, and the attachment 60 further moves to the second hole portion 293 side. To stop doing. In this way, the appendage 60 is detachably attached to the recorder main body 10 in a sliding manner, and is positioned at a predetermined position with respect to the recorder main body 10.

  The user moves the attachment 60 attached to the recorder main body 10 in the direction opposite to that at the time of attachment and arranges the fitting protrusion 67 at a position overlapping the first hole 291, and then moves the attachment 60 downward. By moving it, the appendage 60 can be detached from the recorder main body 10.

According to the above slide structure, the attachment / detachment structure of the appendage 60 can be provided in the drive recorder 1 in a compact manner.
In addition, as shown in FIG. 13, the signal cable 40 used in the present embodiment is provided with a cable body 41 and a male cable provided at the upper end of the cable body 41 and connected to the signal cable connection portion 23 of the recorder body 10. The connector 43 and a male connector 45 provided at the lower end of the cable body 41 and connected to the signal cable connection portion 65 of the appendage 60 are provided.

  Specifically, in this embodiment, two signal cables 40 having different lengths of the cable body 41 are prepared. The short signal cable 40 is used when the appendage 60 is attached to the recorder body 10. The long signal cable 40 is used when the appendage 60 is removed from the recorder body 10. Since the structure of these two signal cables 40 is the same except that the length of the cable body 41 is different, in this specification, these signal cables 40 will be described without distinction using the same reference numerals and the same drawings.

  The first feature of the signal cable 40 is that the male connector 45 connected to the appendage 60 has an L-shaped upper surface 451 and lower surface 453 as shown in FIGS. 14A and 14B. That is, the cable body 41 extends upward. Specifically, the cable body 41 extends upward from a portion exposed from the signal cable connection portion 65 of the appendix 60 at the end opposite to the tip portion where the terminal portion 459 of the male connector 45 is provided. ing.

  The male connector 45 is attached to the left side of the appendage 60. When the attachment 60 is attached to the recorder main body 10, the upper left side of the male connector 45 is disposed approximately below the groove 18 of the recorder main body 10. The cable body 41 extends from the upper left side of the male connector 45.

  For this reason, the fact that the cable body 41 extends from the upper left side of the male connector 45 means that the cable body 41 does not impair the aesthetics of the drive recorder 1 when the male connector 45 is attached to the attachment 60. Can be guided to the groove 18 of the recorder main body 10. Furthermore, such a positional relationship between the cable body 41 and the male connector 45 contributes to good operability regarding attachment and detachment of the male connector 45 to and from the appendage 60.

  The second feature of the signal cable 40 is that the cable body 41 extends upward from the upper surface 431 of the male connector 43 connected to the recorder body 10 as shown in FIGS. 15A and 15B.

  The male connector 43 includes a terminal portion 439 at a lower portion thereof, and the terminal portion 439 is covered with the signal cable connection portion 23 of the recorder body 10 when the male connector 43 is attached to the recorder body 10. On the other hand, the upper portion of the male connector 43 is not covered with the signal cable connection portion 23 and the upper surface 431 is exposed. The cable body 41 extends upward from the exposed upper surface 431.

  The male connector 43 is attached to the upper surface of the recorder body 10. For this reason, the fact that the cable body 41 extends from the upper surface 431 of the male connector 43 contributes to good operability related to attachment and detachment of the male connector 43 to and from the recorder body 10.

  As can be understood from FIG. 1, when the male connector 43 is attached to the recorder main body 10, the portion of the cable main body 41 located near the male connector 43 is wired so as to protrude upward from the recorder main body 10. The However, since the protruding portion is arranged at the upper part of the passenger compartment with the stay 30 on the side, the aesthetic appearance of the drive recorder 1 is not greatly impaired.

  The cable body 41 is once guided upward from the male connector 43 and then guided downward by bending. For this reason, the force which is going to cancel curvature in the cable main body 41 does not act largely by the relationship with gravity. Therefore, when the cable main body 41 is accommodated in the groove 18, the lateral force that causes the cable main body 41 to come out of the groove 18 does not act greatly. Therefore, the connection of the cable main body 41 to the male connector 43 is advantageous in terms of aesthetics.

  Next, the state where the attachment 60 is detached from the recorder body 10 will be described in detail. In this case, as shown in FIG. 16A, the cable main body 41 of the signal cable 40 connected to the recorder main body 10 is hooked on the hooking portion 315 of the stay 30 and passes through the right end of the windshield from the upper part of the passenger compartment. Wired to the dashboard D (see FIG. 2B). Here, a signal cable 40 having a long cable body 41 is used.

  On the other hand, as shown in FIG. 16B, the appendage 60 is attached to the pedestal 80 in a posture that is upside down from the posture that is attached to the cable body 41. The appendage 60 is disposed on the dashboard D so that the rear camera 63 faces the passenger compartment. The male connector 45 of the signal cable 40 is connected to the signal cable connection portion 65 in the same manner as when attached to the recorder body 10 in the appendage 60.

  As shown in FIGS. 17, 18 </ b> A, 18 </ b> B, 19 </ b> A, and 19 </ b> B, the pedestal 80 includes a base portion 81, a movable portion 85, and a ball stud 89 formed integrally with the movable portion 85. The base 81 has a lower surface 811 that contacts the dashboard D. The base 81 has a mountain shape that is raised upward, and includes a socket 813 at the top. The socket 813 is configured to accommodate the ball portion 891 of the ball stud 89. A combination of the ball stud 89 and the socket 813 constitutes a ball joint that connects the movable portion 85 to the base portion 81 so that the movable portion 85 can be displaced.

  The movable portion 85 is configured as a plate having a surface 851 having a shape corresponding to the upper surface of the appendage 60, and functions as a support portion that supports the appendage 60. The movable portion 85 has two fitting holes 87 at positions corresponding to the fitting protrusions 67 of the appendage 60. The two fitting holes 87 correspond to the engaging portions with the appendage 60.

  The fitting hole 87 has the same configuration as the fitting hole 29 (see FIG. 10B) of the recorder body 10. That is, the fitting hole 87 is configured such that the first hole portion 871 and the second hole portion 873 having a shorter width in the front-rear direction than the first hole portion 871 communicate with each other. The first hole portion 871 is formed to a size that allows the fitting protrusion 67 provided in the appendage 60 to be inserted, and the second hole portion 873 is smaller than the width of the head portion 671 of the fitting protrusion 67 in the front-rear direction. Formed.

  As can be understood from the shape of the fitting hole 87, the appendage 60 allows the user to place the fitting protrusion 67 on the first hole portion 871 of the movable portion 85 and the first base portion 674 on the second hole portion 873 side. The attachment 60 is attached and fixed to the movable portion 85 by sliding the appendage 60 along the surface 851 of the movable portion 85 toward the second hole portion 873 in the state of being inserted so as to face. The state in which the appendage 60 is attached to the movable portion 85 is shown in FIGS. 20A, 20B, 21A, and 21B.

  Since the movable portion 85 is connected to the base portion 81 through the ball stud 89, even if the lower surface 811 of the base portion 81 is fixed on the dashboard D of the vehicle, for example, through an adhesive sheet, the attachment 60 on the movable portion 85 is used. Is rotatable around a socket 813 in a wide angle range. Specifically, it is possible to change the direction of 360 degrees on the horizontal plane, and it is possible to incline within a range of about 180 degrees on a plane perpendicular to the horizontal plane.

  According to the drive recorder 1 of the present embodiment described above, the user can drive the drive recorder 1 by fixing the drive recorder 1 to the upper part of the passenger compartment, for example, the windshield W with the appendage 60 attached to the recorder body 10. The recorder 1 can be compactly arranged in the vehicle interior in a posture capable of photographing the outside of the vehicle and the vehicle interior.

  That is, the user can install the front camera 13 and the rear camera 63 in the vehicle interior in a compact manner. Furthermore, the postures of the front camera 13 and the rear camera 63 can be adjusted simultaneously.

  However, in a state where the attachment 60 is attached to the recorder main body 10, there is a possibility that the interior of the vehicle interior cannot be satisfactorily photographed by the rear camera 63 due to the direction and position of the front camera 13. For example, it is not preferable that the drive recorder 1 significantly interferes with the driver's field of view. For this reason, there are restrictions on the installation location of the drive recorder 1.

  Due to this restriction, there is a possibility that an area desired by the user cannot be photographed satisfactorily with the rear camera 63 in a state where the attachment 60 is attached to the recorder body 10. Specifically, there is a possibility that the driver cannot be photographed well with the rear camera 63. This restriction is influenced by the vehicle shape, vehicle size, vehicle interior structure, vehicle compartment size, and the like, and varies greatly depending on the vehicle type.

The drive recorder 1 of the present embodiment can improve the situation in which the shooting environment is limited in this manner by removing the appendage 60 from the recorder body 10.
That is, according to the drive recorder 1 of the present embodiment, the user can adjust the posture of the rear camera 63 almost without being affected by the posture of the front camera 13 by removing the appendage 60 from the recorder body 10. Can do.

  Therefore, the user installs the recorder body 10 on the passenger seat side in the upper part of the passenger compartment with the appendage 60 removed from the recorder body 10, and attaches the appendage 60 to the driver seat on the dashboard D via the pedestal 80. By arrange | positioning in the side, the driver | operator side in a vehicle interior can be image | photographed favorably, suppressing the recorder main body 10 interfering with a driver | operator's view.

  Since the rear camera 63 is not normally installed for the purpose of photographing the outside of the vehicle, the rear camera 63 can be installed at a position on the dashboard D that is lower than the driver's field of view. Even if it is arranged on the seat side, it does not easily interfere with the driver's field of view.

  As described above, according to the present embodiment, when the appendix 60 is attached to the recorder main body 10 and an attempt is made to photograph the inside and outside of the vehicle well, the drive recorder 1 is only at a position that obstructs the driver's view. Even in an environment where the attachment 60 is removed, the attachment 60 is used in a state where it is detached from the recorder main body 10, so that the installation freedom of the recorder main body 10 is increased, and the inside and outside of the vehicle are excellent while ensuring the driver's visibility. Can be taken. Therefore, according to the present embodiment, it is possible to provide the drive recorder 1 that is highly convenient for shooting in a plurality of directions such as outside the vehicle and in the vehicle interior.

  The drive recorder 1 of the present embodiment inputs the video signal of the attachment 60 to the recorder main body 10 via the signal cable 40, and the groove 18 for accommodating a part of the signal cable 40 is provided in the recorder main body 10. It is also meaningful to prepare for the side. Furthermore, the drive recorder 1 has a latching portion 315 for latching the signal cable 40 in a path for guiding the signal cable 40 from the appendage 60 on the dashboard D to the recorder body 10. Therefore, according to this drive recorder 1, the signal cable 40 is not conspicuous and can be stably arranged so as not to be shaken by the vibration of the vehicle.

  In the present embodiment, it is also significant that a sliding engagement structure is adopted as a configuration for detachably attaching the appendage 60 to the recorder body 10. The sliding type engaging structure is a compact structure, and allows the attachment body to be detachably attached to the main body.

  In the present embodiment, the base 80 for supporting the attachment 60 removed from the recorder body 10 and fixing it to the vehicle is fitted on the surface 851 supporting the attachment 60 with the fitting protrusion 67 of the attachment 60. It is also meaningful to have a fitting hole 87 that fits together. According to this configuration, when the appendage 60 is detached from the recorder main body 10, the attachment protuberance 67 for attachment to the recorder main body 10 can be effectively used to stably arrange the appendage 60 on the vehicle.

  In the present embodiment, it is also meaningful that the pedestal 80 includes a movable portion 85 connected through the base portion 81 and the ball stud 89. According to the present embodiment, it is possible to provide the drive recorder 1 with a high degree of freedom regarding the posture of the rear camera 63.

  In addition, it goes without saying that the present disclosure is not limited to the exemplary embodiments described above, and can take various forms. For example, the appendage 60 may be configured to transmit a video signal to the recorder main body 10 by a wireless method as shown in FIG. 22 instead of a wired method using the signal cable 40. In this case, the wireless communication circuits C1 and C2 can be incorporated in each of the recorder body 10 and the appendage 60.

  The power supply to the electric circuit of the appendage 60 may be realized by mounting a rechargeable or non-rechargeable battery on the appendage 60. 23A and 23B, power supply terminal portions T1 and T2 are provided in the fitting hole 29 of the recorder body 10 and the fitting protrusion 67 of the appendage 60, respectively, and as shown in FIG. When the appendage 60 is attached to the recorder body 10, power may be supplied from the recorder body 10 to the appendage 60 through the terminal portions T1 and T2. When the rechargeable battery B is mounted on the appendage 60, the rechargeable battery B may be charged using this supplied power.

  The engagement structure between the recorder main body 10 and the appendage 60 may not be a slide type, may be realized by a snap fit, or other detachable connection structure may be used. From the viewpoint of user convenience, it goes without saying that it is preferable to employ an engagement structure in which the attachment 60 can be attached to and detached from the recorder body 10 without using a tool such as a screwdriver.

  In addition, the attachment location of the appendage 60 in the recorder main body 10 is not limited to the lower surface, but may be a side surface. The engagement structure is provided at a plurality of locations, and the user selectively attaches to one of the locations. The drive recorder 1 may be configured so that the body 60 can be attached.

  The functions of one constituent element in the above embodiment may be distributed among a plurality of constituent elements. Functions of a plurality of components may be integrated into one component. A part of the configuration of the above embodiment may be omitted. At least a part of the configuration of the embodiment may be added to or replaced with the configuration of the other embodiment. Any aspect included in the technical idea specified from the wording of the claims is an embodiment of the present disclosure.
