Description

TECHNICAL FIELD The present invention relates to in-vehicle equipment such as a drive recorder, and more specifically, to an improvement in the mounting structure of in-vehicle equipment of the type that is mounted on the windshield of a vehicle.

A drive recorder that stores vehicle situation information before and after an automobile accident (forward image, vehicle speed, sudden acceleration and deceleration, etc.) will provide useful information for verification in the event of an automobile collision accident. In particular, it is widely used in transportation vehicles such as trucks, commercial vehicles such as taxis and buses, and is also being installed in general vehicles.

This drive recorder is capable of storing forward images for a certain period of time before and after the occurrence of an accident, sudden braking, etc., and driving data indicating the driver's driving operation (brake operation, turn signal operation, driving route, etc.). It is configured. To briefly explain the configuration for storing video data, a CCD camera constantly captures images of the vehicle and its surroundings from the driver's point of view (field of view), and the captured images are stored in a temporary storage memory such as a ring buffer. Remember. The video stored in this temporary storage memory is successively updated to the latest one, and the past video data is held for the set time. On the other hand, drive recorders are equipped with sensors such as acceleration sensors that detect impacts that occur during accidents, sudden braking, or sudden steering. The image of the previous fixed period is read out from the temporary storage memory and stored in non-volatile memory (SD memory card etc.), and after the threshold is exceeded, the image of the CCD camera captured after that is directly or temporarily stored in the non-volatile memory It has a function to save the video and the running data for a predetermined time before and after the impact in the non-volatile memory (SD card) by storing it via the storage memory.
Then, when an accident occurs, it is possible to clearly testify the legitimacy of the driver based on the vehicle condition information (images, etc.) of the own vehicle stored in the nonvolatile memory. In addition, when the drive recorder detects rough and dangerous driving maneuvers such as abrupt steering or braking, it emits a warning sound or the like to call attention to the driver, giving the driver a sense of tension. can.

Since the drive recorder captures and stores images in front of the vehicle, the drive recorder is usually attached to the windshield of the vehicle or the like. Specifically, as shown in Patent Documents 1 and 2, a mounting member having a mounting surface inclined at a predetermined angle with respect to the main body is provided on the upper surface of a flat rectangular main body in which a CCD camera, a sensor, etc. are built, Adhesive tape, double-sided adhesive tape, suction cups, etc. provided on the mounting surface are used to adhere and fix to a predetermined position on the windshield.

However, since the inclination of the windshield differs depending on the type of vehicle, there is a problem that if the mounting structure is fixed, it cannot be mounted depending on the vehicle. The invention disclosed in Patent Document 2 proposes a technique for detecting the orientation of the main body of the drive recorder and correcting the image captured by the CCD camera on the premise that the mounting orientation of the main body of the drive recorder is changed. . Although it is possible to prepare a plurality of types of mounting members (mounting jigs) according to the inclination of the windshield and mount the drive recorder using the mounting jig suitable for the vehicle to be mounted, such a configuration does not Selling multiple types of mounting members as a set is not preferable because the user also purchases unnecessary mounting jigs. Therefore, there is still no suitable drive recorder that can be mounted on vehicles with different inclinations of windshields.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a drive recorder and other in-vehicle equipment that can be used for different types of vehicles with a single unit configuration.

In order to achieve the above object, an in-vehicle device according to the present invention includes (a) a cylindrical case portion, a movable portion for moving electronic components housed in the case portion in a circumferential direction, and and a mounting portion for fixing a case portion to a mounting portion of a vehicle, wherein wiring for supplying power to the electronic component is led out from the side surface of the case portion. As for drawing out the wiring, as in the embodiment, a jack may be provided and the wiring may be attached/detached to/from the jack, or the wiring may be directly connected to the main body.
An in-vehicle device according to the present invention includes (1) a "mounting bracket" comprising a "main body", a ring portion rotatably mounted on the outer peripheral surface of the main body, and a mounting member connected to the outside of the ring portion. and a "fixing member" for fixing the ring portion to the main body.

The fixing member corresponds to the nut member 40 in the embodiment. As described in (2) below, it is preferable to fasten the fixing member to the main body by using a screw mechanism like the nut part, because it can be realized with a simple structure, but it is preferable to fix it using a spring. Alternatively, it may be fixed by an appropriate locking mechanism. Furthermore, the ring portion is not limited to being fixed by sandwiching the ring portion between the fixing member and the main body as in the embodiment. Various mechanisms can be employed, such as fixing by In addition, although the fixing member is detachable from the main body in the embodiment, it is of course possible to prevent it from being detached from the main body. However, if the fixing member is detachable from the main body, the fixing member can be installed in different vehicles in advance, and one main body can be used by transferring between the different vehicles.

Furthermore, in the embodiments, the ring portion is attached to the outer peripheral surface of the main body and arranged so as to be exposed to the outside, but the present invention is not limited to this, and all or part of the ring portion is inside the main body. A stored configuration may also be adopted. In addition, in combination with connecting the mounting member to the outside of the ring portion, if the ring portion is mounted on the outer peripheral surface of the main body and exposed to the outside, the configuration is simplified and the outer peripheral surface of the exposed ring portion is simplified. It is preferable because it is easy to adjust the relative angular position between the ring portion and the main body by holding and rotating the ring portion.

Further, although the rotatable angle is the entire circumference of 360 degrees in this embodiment, it may be a predetermined angle range. Furthermore, if the shape of the main body is based on a cylindrical shape as in the embodiment, the design is consistent with that of the ring portion and is also pleasing to the eye. can be taken.

Further, if the ring portion is attached to one end side of the main body as in the embodiment, it is easy to adjust the angle and fix it, but it is also possible to adopt a layout in which it is installed near the center.

In the present invention, since the ring portion is rotatably attached to the main body, the ring portion and the main body are rotated relative to each other before fixing to the main body to adjust the relative angular position of the main body and the ring portion (bracket). Can be set to any desired state. And by fixing it in that state, it is possible to change and adjust the relative angular position between the mounting member fixed to the windshield etc. by adhesion etc. and the main body, while adopting a single unit configuration, different vehicles ( different windshield angles).

(2) The fixing member may fix the ring portion by sandwiching the ring portion with the main body. This is preferable because switching between fixing (positioning by stopping rotation) and releasing (rotatable and angle-adjustable) of the ring portion can be easily performed. In particular, if the clamping force can be adjusted, temporary fixing can be performed in a lightly tightened state, and the position adjustment work can be performed more easily.

(3) It is preferable to interpose a packing between the fixing member and the ring portion. By using the elastic force of the packing, the gap between the fixing member and the main body is narrowed, and in addition to the effect of tightening the ring portion, the elastic force of the packing can improve the tightening force. Therefore, for example, the distance between the fixing member and the main body is set slightly wider than the width of the ring (the distance in the case of making this slightly wider is appropriately changed depending on other factors such as the thickness of the packing), and the elastic force of the packing is increased. Temporary fixation can be achieved by fixing the ring portion by using it. By exhibiting such a temporary fixing effect, for example, when installing in a vehicle, the main body must always be supported by hand if there is no packing, but if there is packing, it is possible to release the hand. Also, when adjusting the angle, for example, it is difficult to check the angle by supporting the ring portion by hand while it is pressed against the main body. Even if the angle is temporarily fixed, it is possible to easily confirm whether or not the angle can be fixed. Therefore, it exhibits an excellent effect of facilitating installation and adjustment even in a narrow space such as a vehicle interior.

Furthermore, when rubber is used as the packing, in addition to the temporary fixing effect described above, it also exhibits anti-vibration and anti-slip effects, so it exhibits excellent stability not only when installing in-vehicle equipment but also during use. It is more preferable because

(4) The one end of the main body and the fixing member may be connected by a screw mechanism. With such a configuration, by tightening the screw, the distance between the main body and the fixing member can be narrowed, and the mounting bracket can be firmly fixed with a simple structure. In this embodiment, the male thread is formed on the main body side and the female thread is formed on the nut portion side, which is the fixing member. .

(5) Concavities and convexities are formed on at least a part of the facing surfaces of the main body and the ring portion, and when the ring portion is fixed by the fixing member, the concavities and convexities match each other. good. Rotation of the mounting bracket can be restrained to some extent by the tightening force between the fixing member and the main body. Moreover, although the unevenness|corrugation was formed continuously over the perimeter in embodiment, you may arrange|position discretely. However, it is preferable to form them continuously because the rotation angle can be finely adjusted.

(6) Preferably, the end face is positioned on a plane orthogonal to the axis of the ring portion. That is, in order to suppress the rotation, various positions (surfaces) can be used for the facing surface forming the unevenness. can also be set to However, if it is formed on the inner peripheral surface, when adjusting the angle, it is necessary to shift the ring part to a position where the unevenness of the main body is not formed, set the angle in that state, and then insert it again. be. Therefore, as in (6), if the surface (side surface) perpendicular to the axis of the ring portion is provided with unevenness, there is no such problem (rotation becomes possible if the firm engagement of the unevenness is released). preferable. The invention described in (6) is realized by the embodiment.

(7) It is preferable that the unevenness has a shape having an inclined surface that is inclined along the rotation direction of the ring portion. The shape of the inclined surface may be a flat surface (taper: triangular wave-like unevenness) as in the embodiment, may be appropriately curved (wavy shape), or may be spherical (hemispherical). well, and can take a variety of forms. Since it is slanted along the direction of rotation, even if the protrusions and recesses are fitted to each other to some extent, the fixing force to the ring portion is weak (the tightening force between the main body and the fixing member is weak). , when a strong force is applied in the direction of rotation, it is possible to overcome the unevenness of each other and rotate, that is, the angle can be adjusted. On the other hand, if the unevenness has a side wall extending in a direction perpendicular to the direction of rotation, for example, like a square wave, it will be in a completely fitted state, making adjustment difficult (angle adjustment in a state where the fitting is released). Is required).

(8) It is preferable that the installation surface of the switch formed on the surface of the main body is a flat surface, and the field of view of the camera is directed to the opposite side of the installation surface. (9) In this case, it is more preferable that the direction of the flat surface and the direction of the field of view are set to be perpendicular to each other. When a camera is provided and the front is photographed like a drive recorder, it is difficult to directly confirm the direction of the camera facing forward from the inside of the vehicle. However, since the installation surface of the switch (which faces the inside of the vehicle because it is operated by the driver, etc.) is made flat and the field of view of the camera is directed to the opposite side of the flat surface, the installation surface (flat) Since the orientation of the camera with respect to the surface is known, the orientation of the camera can be estimated from the orientation of the installation surface. At this time, if the direction of the camera is perpendicular to the flat surface as in invention (9), for example, if the installation surface is parallel to the vertical direction, the camera will face the horizontal direction. , the direction of which can be inferred more easily. However, even if they are not necessarily perpendicular to each other, there is no problem because it can be estimated if the orientation of the camera with respect to the installation surface is determined.

(10) It is preferable that the GPS antenna built in the main body is arranged obliquely upward. The slanted upward arrangement means that the GPS antenna surface is oriented obliquely upward with reference to the basic posture of the main body (the standard posture when the in-vehicle device is installed in the vehicle). By doing so, for example, even if the orientation of the main body (for example, the orientation of the camera in the case of a built-in camera) is directed downward, the GPS antenna can obtain good GPS reception sensitivity.

(11) It is preferable that wiring for supplying power to an electronic device mounted in the main body is led out from the side surface of the main body. As for drawing out the wiring, as in the embodiment, a jack may be provided and the wiring may be attached/detached to/from the jack, or the wiring may be directly connected to the main body. In either case, if the wiring (power supply) is drawn out from the side, the wiring can be hidden behind the rear-view mirror, which makes the appearance more beautiful.

(12) An operation switch may be arranged on the front surface of the main body, and a volume operation section for adjusting the volume of a built-in speaker may be arranged on the side surface of the main body. In this way, switches that are frequently used are placed on the front side, so that they are easy to operate.

(13) The main body is provided with a card slot for loading a memory card for storing recorded data, and the outlet of the card slot is set on the end face opposite to the fixing bracket. do it. This makes it easier to attach and remove a memory card such as an SD card from the card slot.

(14) The fixing member may be attached to a side surface of the main body, a part of which may be provided with an opening, and a side surface of the main body located within the opening may be provided with an interface with the outside. The opening corresponds to the "through hole 42" in the embodiment. Also, the interface corresponds to the DC jack 15 and the volume dial 23 in the embodiment. Thus, by providing an opening when the fixing member is attached to the side surface of the main body, a part of the side surface of the main body can be exposed to the outside through the opening. Therefore, by arranging an interface with the outside mounted inside the main body in such an exposed portion, it is possible to efficiently install the operation target in the limited space of the main body. Furthermore, by locating the interface and the fixing member close to each other, the user can easily pay attention to the state of the fixing member when operating the interface, and can naturally and easily check whether there is any looseness or the like.
(15) The in-vehicle device having each of the configurations described above may be a drive recorder. Of course, other in-vehicle devices may be used.

In the present invention, since the ring portion of the mounting bracket is rotatably attached to the main body, it is possible to change the relative rotational angle relationship between the mounting member of the mounting bracket and the main body. The configuration can accommodate different types of vehicles.

A preferred embodiment of a drive recorder according to the present invention will be described below with reference to the accompanying drawings. First, the drive recorder of the present embodiment has a cylindrical main body 10 and has a mounting bracket 30 attached to one axial end of the main body 10 .

The main body 10 is configured by butting together a first case 11 and a second case 12 which are divided into two (halved) front and rear. As shown in FIGS. 2 to 4 and the like, the one end portions 11a and 12a of the first case 11 and the second case 12 are formed to be one size smaller in external dimensions, and the one end portions 11a and 12a and the axis of the main body are formed. A step is formed between the central part of the direction. A triangular wave-like (sawtooth-like) tooth portion 17 is formed on the wall surface having the step. Furthermore, a male thread 18 is formed on the outer peripheral surface of the distal end side of the one end portions 11 a and 12 a of the first case 11 and the second case 12 .

The mounting bracket 30 is erected on a ring portion 31 having an inner diameter substantially matching (slightly larger) than the outer diameters of the one ends 11 a and 12 a of the first case 11 and the second case 12 , and the outer peripheral surface of the ring portion 31 . and a mounting plate 33 provided at the tip of the connecting column portion 32 . As shown in FIG. 5 , the mounting plate 33 is arranged obliquely at a predetermined angle with respect to the diameter direction of the ring portion 31 .

Further, on one side of the ring portion 31 (the side facing the main body 10), a tooth portion 34 is formed over the entire circumference. The tooth portion 34 is set to have the same size and shape so as to match the tooth portion 17 formed on the main body 10 . Furthermore, as shown in FIG. 6, the width D of the ring portion 31 is substantially the same as the width D1 of the flat portion (region where the male screw 18 is not formed) of the one ends 11a and 12a of the first case 11 and the second case 12. I have to. Of course, it may be set wider than D1 (D1<D), but in that case, it should be set shorter than the width D2 to the tip including the male screw 18 (D1<D<D2). A nut member 40 is attached to the male screw 18 . The nut member 40 is in the form of a flat disk-shaped cap, and has a female thread formed on its inner peripheral surface 41 to match the male thread 18 . A circular through hole 42 is formed in the central portion of the nut member 40 . Small semicircular projections 11d and 12d (small circular projections) of the main body are exposed to the outside from the through holes 42, and user operation objects such as the volume dial 23 and the DC jack 15 are located on the exposed portions of the projections. are provided. By adopting such a configuration, it is possible to install the operation target in the limited space of the main body 10, and as a result of attracting the user's attention during operation, it is possible to easily check whether the nut member 40 is loose. .

As a result, when the ring portion 31 is attached to the one ends 11a and 12a of the first case 11 and the second case 12, the ring portion 31 rotates around the central axis of the first case 11 and the second case 12. It can be rotated forward and backward relative to the portions 11a and 12a. By engaging the teeth 17 provided on the main body 10 with the teeth 34 provided on the ring portion 31, the rotation is suppressed.

On the other hand, when the ring portion 31 is attached to the one end portions 11 a and 12 a of the first case 11 and the second case 12 as described above, the male screw 18 protrudes outside the ring portion 31 . Therefore, the nut member 40 is attached to the projecting male screw 18 . By firmly fastening the female thread of the nut member 40 and the male thread 18 of the main body 10, the gap between the nut member 40 and the stepped portion where the tooth portion 17 of the main body 10 is formed is narrowed, and the main body 10 and the nut The ring portion 31 can be sandwiched between the member 40 and the member 40 with a predetermined force. When the nut member 40 is loosened, the rotation of the ring portion 31 and thus the mounting bracket 30 is prevented by engaging the tooth portions 17 and 34 with each other. Therefore, the relative angular positional relationship between the main body 10 and the mounting bracket 30 can be set (adjusted) to an arbitrary position and fixed at that position. In other words, when the plane (direction) parallel to the joint surfaces of the first case 11 and the second case 12 is defined as the basic vertical direction of the main body 10, the angle between the vertical direction and the mounting plate 33 of the mounting bracket 30 is can be changed.

A double-sided tape (not shown) or other adhesive member is attached to the upper surface of the mounting plate 33, and the double-sided tape is used to adhere and fix to the windshield of the vehicle. Therefore, the drive recorder of this embodiment can be adjusted according to various windshield angles (25 to 75 degrees). That is, the mounting plate 33 is parallel to the angle of the windshield, but since the relative angle of the main body 10 to the mounting plate 33 (mounting bracket 30) can be adjusted as described above, the angle of the mounting plate 33 (windshield) Regardless, the body 10 can have its base vertical orientation parallel to, for example, a vertical plane (relative to the ground). Of course, the angle formed by the basic vertical direction of the main body 10 and the vertical plane to the ground can also be set to an appropriate angle. Therefore, one drive recorder can be installed in different types of vehicles.

Furthermore, by firmly tightening the nut member 40, the teeth 17 of the main body 10 and the teeth 34 of the mounting bracket 30 are firmly meshed with each other to reliably prevent the rotation thereof. Even if a shock is applied to the body 10, the orientation and posture of the main body 10 can maintain the basic posture when the drive recorder is attached to the windshield (as long as the mounting plate 33 does not peel off from the windshield) and can be firmly fixed. can.

Furthermore, as shown in FIG. 3 and the like, a packing 50 made of an elastic material such as rubber is arranged inside the nut member 40 (on the main body 10 side). The inner diameter of the packing 50 is set to be substantially the same as or slightly larger than the outer diameter of the male thread 18 of the main body 10 , and the outer diameter of the packing 50 is set to be one size smaller than the outer diameter of the ring portion 31 . The thickness of the packing 50 is made uniform over the entire circumference. In the present embodiment, the width D of the ring portion 31 and the width D1 of the flat portions (regions where the male threads 18 are not formed) of the one ends 11a and 12a of the first case 11 and the second case 12 are substantially the same. When the ring portion 31 is attached to the one end portions 11a and 12a, the tips of the flat portions of the one end portions 11a and 12a and the end surface of the ring portion 31 on the side of the nut member 40 are substantially flush with each other. One surface of the packing 50 can contact the main body 10 and the ring portion 31 beyond the male thread 18 , and the other surface of the packing 50 contacts the inner surface of the nut member 40 .

When the width D of the ring portion and the lengths D1 and D2 of the one end portions 11a and 12a are set so as to satisfy D1<D<D2, the packing 50 has a ring shape (doughnut shape) with a uniform thickness. ), it is preferable to provide the ring portion with an annular convex portion that fits in the stepped portion between D and D1.

By additionally arranging the packing 50 in this way, loosening due to vibration can be prevented, unnecessary recording triggered by vibration as a drive recorder can be prevented, and an accident image can be more reliably recorded at the time of impact. Of course, this packing 50 does not necessarily have to be provided.

Next, the arrangement structure of each component to be mounted inside the main body 10 and the external exposure structure of the component will be described. As shown in FIG. 7, a CCD camera 13, a GPS antenna 14, a DC jack 15, a power supply circuit, and the like are mounted on the first case 11 side. A circular opening 11b is formed at a predetermined position of the first case 11 (a position facing the CCD camera 13), and the CCD camera 13 is exposed to the outside through the opening 11b.

In addition, the GPS antenna 14 is arranged at a predetermined angle with respect to the vertical direction of the main body 10 (the plane (direction) parallel to the joint surfaces of the first case 11 and the second case 12), and is directed obliquely upward. (See FIG. 13, etc.). As a result, even when the field of view of the CCD camera 13 is set obliquely downward when mounted on a truck or the like, good GPS reception sensitivity can be obtained.

As shown in FIGS. 7 and 8, the DC jack 15 is arranged parallel to the axial direction of the main body 10 and exposed at one end of the main body 10 . That is, as shown in FIG. 1 and the like, a window hole 11c is formed at a predetermined position in the end surface (side surface perpendicular to the axial direction) of the one end portion 11a of the first case 11, and the DC jack 15 extends through the window hole 11c. exposed to the outside through By attaching a DC plug (not shown) attached to one end of a power cable connected to a cigar socket, for example, to the DC jack 15, the drive recorder of the present embodiment can be supplied with power from the vehicle battery. and Since the power cable is pulled out from the side of the main body 10 in this way, the power cable can be hidden in the rearview mirror by attaching the drive recorder to the side of or near the rearview mirror, and the appearance is improved. be able to.

Further, as shown in FIGS. 7 and 8, a locking claw 12c is provided at a predetermined position on the joint surface of the second case 12. As shown in FIG. A recess for locking is formed in the joint surface of the first case 11 at a position corresponding to the locking claw 12c. and recesses engage with each other to position and prevent misalignment (particularly axial movement). Further, small semicircular projections 11d and 12d are formed on the end surfaces (side surfaces perpendicular to the axial direction) of the one ends 11a and 12a of the first and second cases 11 and 12, respectively. When the first and second cases 11 and 12 are butted against each other, both convex portions 11d and 12d are brought against each other to form a small circular convex portion. By fitting an annular stop member 16 to the protrusions 11d and 12d, it is possible to further enhance the effect of preventing deviation due to vibration. Furthermore, when the nut member 40 is tightened, the protrusions 11d and 12d enter the through hole 42 of the nut member 40 and are exposed to the outside from the axial side surfaces.

On the other hand, as shown in FIGS. 9 and 10, on the side of the second case 12, a man-machine interface such as a switch section 20, a display section 21, an SD card slot 22, a volume dial 23, etc., and a control circuit are mounted. . The control circuit is a circuit for realizing the basic functions of the drive recorder. Data such as captured images are stored in a non-volatile memory. Although not shown, an output device such as a speaker is also mounted. For example, the operation sound of the switch unit 20 and various messages (guides, warnings, etc.) are reported from the speaker. A volume dial 23 adjusts the output level of this speaker. Further, on the second case 12 side, an acceleration sensor for detecting a collision or the like and other electronic components and electronic circuits for realizing the functions of a drive recorder are incorporated.

Furthermore, as shown in FIG. 11, the first case 11 and the second case 12 have flat surfaces 11e and 12e parallel to the joint surface on the opposite side to the joint surface. Therefore, both flat surfaces 11e and 12e are set parallel (see FIG. 12). The CCD camera 13 is exposed to the outside from the flat surface 11e of the first case 11 (the circular opening 11b is formed in this flat surface 11e), and the direction of the field of view of the CCD camera 13 is aligned with the flat surface 11e. It is set so as to be in a direction orthogonal to 11e.

On the other hand, on the flat surface 12e of the second case 12, the switch section 20 and the display section 21 are arranged. When the drive recorder is attached to the windshield, the first case 11 (CCD camera 13) faces the front of the vehicle and the second case 12 faces the inside of the vehicle. Therefore, it is difficult for a user such as a driver in the vehicle to directly check the orientation of the CCD camera 13 . However, in the present embodiment, the flat surface 11e of the first case 11 and the flat surface 12e of the second case 12 are set to be parallel, so that the flat surface 12e of the second case 12 faces the inside of the vehicle. is the direction of the flat surface 11e of the first case 11 and the CCD camera 13 as it is, so the direction of the CCD camera 13 can be estimated by looking at the directions of the switch unit 20 and the display unit 21 (flat surface 12e). The orientation of the CCD camera 13 can be easily adjusted.

The volume dial 23 mounted in the second case 12 is arranged on the one end 12a side of the second case 12, and is formed in a small semicircular shape on the end surface (side surface perpendicular to the axial direction) of the one end 12a. A part of the volume dial 23 protrudes outside from a longitudinal slit 12f provided in the convex portion 12d of the dial 23, so that it can be rotated. Furthermore, the SD card slot 22 is arranged on the side surface of the second case 12 opposite to the one end 12a (see FIG. 11, etc.). In this way, among the man-machine interfaces, by arranging frequently used items such as the switch unit 20 on the front side and arranging less frequently used items such as the volume dial 23 and the SD card slot 22 on the side surface, , operability is improved. Furthermore, since the SD card slot 22 is arranged on the side, there is no front crow or roof in the insertion/removal direction of the SD card 60. Therefore, regardless of the tilt angle of the windshield to which the drive recorder is installed and the orientation of the drive recorder, the SD card can be The card 60 can be easily attached and detached. Moreover, since the SD card slot 22 is arranged on the side opposite to the mounting bracket 30, the SD card 60 can be easily attached to and removed from the SD card slot 22. FIG.

Furthermore, in the form shown in FIG. 1 and the like, when viewed from the driver, the SD card slot 22 is located on the right side, and the mounting bracket 30 (DC jack 15, volume dial 23) is located on the left side.
