The head 671 extends horizontally (front-back, left-right direction) in a plate shape at the upper part of the first base portion 674 and the second base portion 675. The first base portion 674 is provided so as to be arranged on the second hole portion 293 side of the second base portion 675 when the fitting protrusion 67 is inserted into the fitting hole 29 of the recorder main body 10.

As can be understood from the shapes of the fitting hole 29 and the fitting protrusion 67, the user can attach the fitting protrusion 67 to the first hole portion 291 of the recorder main body 10 and the first base portion 674 to the second. The appendage 60 is attached to and fixed to the recorder main body 10 by sliding the appendage 60 toward the second hole 293 side along the lower surface of the recorder main body 10 in a state of being inserted so as to face the hole 293 side.

When the appendage 60 is attached to the recorder body 10, the head 671 of the fitting projection 67 is arranged inside the housing 11 of the recorder body 10 and constitutes the periphery of the second hole 293 of the housing 11. It interferes with the part and is prevented from moving downward. Further, the second base portion 675 of the fitting projection 67 interferes with the housing 11 at the boundary between the first hole portion 291 and the second hole portion 293, and the appendage 60 further moves to the second hole portion 293 side. Stop doing. In this way, the accessory 60 is detachably attached to the recorder main body 10 by a slide method, and is positioned at a predetermined position with respect to the recorder main body 10.

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

According to the above slide structure, the attachment / detachment structure of the accessory 60 can be compactly provided on the drive recorder 1.
In addition, as shown in FIG. 13, the signal cable 40 used in the present embodiment is a male type provided at the cable main body 41 and the upper end of the cable main body 41 and connected to the signal cable connecting portion 23 of the recorder main body 10. It includes a 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 accessory 60.

Specifically, in the present embodiment, two signal cables 40 having different lengths of the cable main 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 structures of these two signal cables 40 are the same except that the length of the cable body 41 is different, these signal cables 40 will be described in the present specification 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 a lower surface 453, as shown in FIGS. 14A and 14B. The cable body 41 extends upward from the cable body 41. Specifically, the cable body 41 extends upward from a portion exposed from the signal cable connection portion 65 of the accessory 60 at the end portion opposite to the tip portion provided with the terminal portion 459 of the male connector 45. ing.

The male connector 45 is mounted on the left side of the appendage 60. Then, when the appendage 60 is attached to the recorder main body 10, the left side of the upper surface of the male connector 45 is arranged approximately below the groove 18 of the recorder main body 10. The cable body 41 extends from the left side of the upper surface of the male connector 45.

Therefore, the fact that the cable body 41 extends from the left side of the upper surface of the male connector 45 means that the cable body 41 does not spoil the aesthetic appearance of the drive recorder 1 when the male connector 45 is attached to the accessory 60. Can be guided to the groove 18 of the recorder body 10. Further, such a positional relationship between the cable body 41 and the male connector 45 contributes to good operability regarding attachment / detachment of the male connector 45 to the appendage 60.

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

The male connector 43 includes a terminal portion 439 below the male connector 43, and the terminal portion 439 is covered with a signal cable connection portion 23 of the recorder main body 10 when the male connector 43 is attached to the recorder main body 10. On the other hand, the upper portion of the male connector 43 is not covered by 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 mounted on the upper surface of the recorder main body 10. Therefore, the fact that the cable body 41 extends from the upper surface 431 of the male connector 43 contributes to good operability regarding attachment / detachment of the male connector 43 to 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 in the vicinity of the male connector 43 is wired so as to project upward from the recorder main body 10. NS. However, since this protruding portion is arranged in the upper part of the vehicle interior with the stay 30 present next to it, the aesthetic appearance of the drive recorder 1 is not significantly impaired.

The cable body 41 is once guided upward from the male connector 43, and then is guided downward by bending. Therefore, the force for eliminating the curvature in the cable body 41 does not greatly act in relation to gravity. Therefore, when the cable body 41 is housed in the groove 18, the lateral force that causes the cable body 41 to come off the groove 18 does not exert a large force. Therefore, such a connection of the cable body 41 to the male connector 43 is also advantageous in terms of aesthetics.

Subsequently, the state in which the appendage 60 is removed from the recorder main body 10 will be described in detail. In this case, as shown in FIG. 16A, the cable body 41 of the signal cable 40 connected to the recorder body 10 is hooked on the hooking portion 315 of the stay 30 and passes from the upper part of the passenger compartment to the right end of the windshield. Wired to 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 upside down from the posture of being attached to the cable body 41. The accessory 60 is arranged on the dashboard D so that the rear camera 63 faces the passenger compartment side. The male connector 45 of the signal cable 40 is connected to the accessory 60 to the signal cable connection portion 65 in the same manner as when it is attached to the recorder main body 10.

The pedestal 80 includes a base 81, a movable portion 85, and a ball stud 89 integrally formed with the movable portion 85, as shown in FIGS. 17, 18A, 18B, 19A, and 19B. The base 81 has a lower surface 811 in contact with the dashboard D. The base 81 has a mountain-shaped shape that rises upward, and a socket 813 is provided on the top thereof. The socket 813 is configured to accommodate the ball portion 891 of the ball stud 89. By combining the ball stud 89 and the socket 813, the pedestal 80 is configured with a ball joint that displaceably connects the movable portion 85 to the base 81.

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 for supporting 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 engagement portion with the appendage 60.

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

As can be understood from the shape of the fitting hole 87, the user attaches the fitting protrusion 67 to the first hole portion 871 of the movable portion 85, and the first base portion 674 to the second hole portion 873 side. The appendage 60 is attached to and fixed to the movable portion 85 by sliding the appendage 60 toward the second hole 873 side along the surface 851 of the movable portion 85 while being inserted so as to face the movable portion 85. The state in which the accessory 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 81 through the ball stud 89, even if the lower surface 811 of the base 81 is fixed on the dashboard D of the vehicle, for example, through an adhesive sheet, the appendage 60 on the movable portion 85 Is rotatable about a wide angle range around the socket 813. Specifically, it is possible to change the direction by 360 degrees on the horizontal plane, and it is possible to incline within a range of about 180 degrees on the plane perpendicular to the horizontal plane.

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

That is, the user can compactly install the front camera 13 and the rear camera 63 in the vehicle interior. Further, the postures of the front camera 13 and the rear camera 63 can be adjusted at the same time.

However, when the accessory 60 is attached to the recorder main body 10, the direction and position of the front camera 13 may be restricted, and the rear camera 63 may not be able to take a good picture of the interior of the vehicle. For example, it is not preferable that the drive recorder 1 greatly interferes with the driver's field of vision. Therefore, there are restrictions on the installation location of the drive recorder 1.

Due to this limitation, when the accessory 60 is attached to the recorder main body 10, the rear camera 63 may not be able to satisfactorily photograph the area desired by the user. Specifically, there is a possibility that the rear camera 63 cannot take a good picture of the driver. It should be noted that this restriction is affected by the vehicle shape, vehicle size, vehicle interior structure, vehicle interior size, etc., 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 restricted by removing the accessory 60 from the recorder main body 10.
That is, according to the drive recorder 1 of the present embodiment, the user adjusts the posture of the rear camera 63 by removing the accessory 60 from the recorder main body 10 so as to be substantially unaffected by the posture of the front camera 13. Can be done.

Therefore, the user installs the recorder body 10 on the passenger seat side in the upper part of the passenger compartment with the accessory 60 removed from the recorder body 10, and installs the accessory 60 in the driver's seat on the dashboard D via the pedestal 80. By arranging it on the side, it is possible to take a good picture of the driver side in the vehicle interior while suppressing the recorder main body 10 from interfering with the driver's field of view.

Since the rear camera 63 is not normally installed for the purpose of photographing the outside of the vehicle, it can be installed at a position on the dashboard D which is lower than the driver's field of view. Therefore, the accessory 60 operates more than the recorder body 10. Even if it is placed on the seat side, it is unlikely to interfere with the driver's field of vision.

As described above, according to the present embodiment, when the accessory 60 is attached to the recorder main body 10 and an attempt is made to take a good picture of the inside and outside of the vehicle, the drive recorder 1 is located only at a position that obstructs the driver's field of vision. By using the accessory 60 with the accessory 60 removed from the recorder body 10, the degree of freedom in installing the recorder body 10 is increased, and the driver's field of vision is well secured while the inside and outside of the vehicle are good. Can be taken. Therefore, according to the present embodiment, it is possible to provide the drive recorder 1 which is highly convenient for photographing in a plurality of directions such as outside the vehicle and inside the vehicle.

The drive recorder 1 of the present embodiment inputs the video signal of the accessory 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. Further, the drive recorder 1 has a hooking portion 315 for hooking the signal cable 40 on the path leading the signal cable 40 from the accessory 60 on the dashboard D to the recorder main body 10. Therefore, according to the drive recorder 1, the signal cable 40 can be stably arranged so as not to be conspicuous and to be shaken by the vibration of the vehicle.

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