Description

  The present invention relates to an in-vehicle device such as a drive recorder, and more specifically to an improvement in an attachment structure in an in-vehicle device of a type that is particularly attached to a windshield of a vehicle.

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

  This drive recorder is capable of storing a front video and a driving data indicating a driver's driving operation (brake operation, turn signal operation, driving route, etc.) for a certain period before and after the occurrence of an accident or sudden braking. It has a configuration. Briefly explaining the configuration for storing video data, the CCD camera always images the vehicle and surroundings from the viewpoint (view) of the driver, and the captured video is stored in a temporary storage memory such as a ring buffer. Remember. The video stored in the temporary storage memory is sequentially updated to the latest one, and the past video data is held for the set time. On the other hand, the drive recorder is equipped with a sensor that detects an impact such as an acceleration sensor or an impact that occurs during sudden braking or sudden steering. If the output value of the sensor exceeds the threshold, the threshold is exceeded (impact detection). The previous video for a certain period is read from the temporary storage memory and stored in a non-volatile memory (such as an SD memory card). After the threshold value is exceeded, the captured image of the CCD camera is directly or temporarily stored in the non-volatile memory. By storing via a storage memory, it has a function to save images and running data for a predetermined time before and after the impact in a nonvolatile memory (SD card).

  When an accident occurs, it is possible to clearly testify the validity of the driver based on the vehicle status information (video etc.) of the own vehicle stored in the non-volatile memory. In addition, when the drive recorder detects a rough and dangerous driving operation such as a sudden handle or a sudden brake, it may give a certain tension to the driver by alerting the driver with a warning sound or the like. it can.

Since this drive recorder captures and stores a front image of the vehicle, the drive recorder is usually attached to the windshield of the vehicle. 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, and the like are incorporated, Adhesive and fixed in place on the windshield using adhesive tape, double-sided adhesive tape, suction cups, etc. provided on the mounting surface.

  However, since the inclination of the windshield differs depending on the type of vehicle, if the mounting structure is fixed, there is a problem that it cannot be mounted depending on the vehicle. In the invention disclosed in Patent Document 2, on the premise that the mounting posture of the main body of the drive recorder is changed, a technique for detecting the posture of the main body and correcting the image taken by the CCD camera is proposed. . And while preparing multiple types of mounting members (mounting jigs) according to the inclination of the windshield and attaching the drive recorder using a mounting jig suitable for the vehicle to be mounted, in such a configuration, When a plurality of types of attachment members are sold as a set, an attachment jig unnecessary for the user is purchased, which is not preferable. Therefore, there is still no suitable drive recorder that can be mounted in correspondence with vehicles having different windshield tilts.

  An object of the present invention is to provide a drive recorder and other in-vehicle devices that can handle different types of vehicles with a single unit configuration.

In order to achieve the above-described object, the in-vehicle device according to the present invention needs to (1) adjust the posture of the electronic component that rotates integrally with the case by rotating the case portion that stores the electronic component. A vehicle-mounted device comprising: the case portion; a ring portion that is rotatably mounted on the case portion; and an attachment member that is connected to the outside of the ring portion and is fixed to an attachment location of the vehicle. “A mounting bracket” and a fixing member that fixes the ring portion to the case portion, and a portion of the case portion that faces the inner peripheral surface of the ring portion is equal to or smaller than the inner diameter of the ring portion. At the same time, an arc surface for guiding the rotation is formed .

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 using a screw mechanism like a nut portion because it can be realized with a simple configuration, but it is fixed using a spring. Or may be fixed by an appropriate locking mechanism. Further, the present invention is not limited to the one in which the ring portion is sandwiched and fixed between the fixing member and the case portion (the “main body 10” in the embodiment) as in the embodiment, and for example, extends from the outside to the inside of the ring portion. Various mechanisms such as fixing by screwing using screws (bolts) or the like can be adopted. In the embodiment, the fixing member is detachable from the case portion (main body) . However, the fixing member may of course not be detached from the main body. However, if the fixing member can be detached from the main body, the fixing member can be installed in different vehicles in advance, and one main body can be used by changing between the different vehicles.

Further, in the embodiment, the ring portion is mounted on the outer peripheral surface of the case portion (main body) and is arranged so as to be exposed to the outside, but the present invention is not limited to this, and the ring portion is wholly or partially. May be configured to be housed in the case part (main body) . In addition, coupled with connecting the mounting member to the outside of the ring part, the ring part is attached to the outer peripheral surface of the case part (main body) and exposed to the outside, so that the structure becomes simple and the exposed ring It is preferable because it is easy to adjust the relative angular position between the ring part and the main body by rotating with the outer peripheral surface of the part.

Further, in this embodiment, the rotatable angle is 360 degrees, but it may be a predetermined angle range. Furthermore, if the shape of the case part (main body) is based on an overall cylindrical shape as in the embodiment, the design is uniform with the ring part, but it is not necessarily required to be cylindrical. Any shape can be taken.

Furthermore, if the mounting position of the ring part is attached to one end side of the case part (main body) as in the embodiment, the angle can be easily adjusted and fixed, but the layout installed from the center is adopted. Also good.

In the present invention, the ring portion, so rotatably mounted with respect to the case portion (body), before fixing to the case portion (body), body and ring portion rotated relative to the ring portion and the body The relative angular position of (bracket) can be set to a desired state. And by fixing in that state, it is possible to change / adjust the relative angular position between the mounting member fixed to the windshield or the like by bonding or the like and the case part (main body) , while adopting a single unit configuration. Can be mounted on different vehicles (different windshield angles).

(2) The said fixing member shall clamp the said ring part between the said case parts, and shall fix the ring part. This is preferable because it can be easily switched between fixing (positioning by stopping rotation) and releasing (rotating and adjusting the angle) of the ring portion. In particular, if the pinching force can be adjusted, temporary fixing can be performed in a lightly tightened state, and the position adjustment operation can be performed more easily.

(3) It is better if a packing is interposed between the fixing member and the ring portion. By using the elastic force of the packing, the tightening force can be improved by the elastic force of the packing in addition to the effect of tightening the ring portion by narrowing the distance between the fixing member and the main body. Therefore, for example, the distance between the fixing member and the case portion (main body) is set to be 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 packing. If the ring portion is fixed by using the elastic force of, temporary fixing can be performed. By exhibiting the temporary fixing effect in this manner, for example, when mounting in a vehicle, the case portion (main body) must always be supported by hand if there is no packing, but if there is packing, the hand can be released. When adjusting the angle or the like, it is difficult to check the angle by supporting the ring part against the case part (main body) by hand, for example, but it is temporarily fixed with packing. Therefore, even if it is not supported by hand, it can be easily confirmed whether the angle can be fixed with the angle temporarily fixed. Therefore, the excellent effect of facilitating installation and adjustment even in a narrow space inside the vehicle is exhibited.

  In addition, when rubber material is used for the packing, in addition to the temporary fixing effect described above, it also exhibits vibration prevention and anti-skid effects, so it has excellent stability not only when mounting on-vehicle equipment but also when used. Therefore, it is more preferable.

(4) The fixing member may be connected to the case portion by a screw mechanism. With such a configuration, by fastening the screw, the interval between the case portion (main body) and the fixing member can be narrowed, and the mounting bracket can be firmly fixed with a simple configuration. In this embodiment, the male thread is formed on the case part (main body) side and the female thread is formed on the nut part side which is a fixing member. Of course it is good.

(5) Concavities and convexities are formed on at least a part of the inner peripheral surface of the ring portion and the facing surface of the case portion facing the ring portion, and the ring portion and the case portion rotate at least without the unevenness being aligned. possible and position it becomes movable in the axial direction until made, the when the ring portion is fixed by the fixing member, not good when the unevenness is such mutual coincidence.

(6) Preferably, when unevenness is formed on at least a part of the side surface orthogonal to the inner peripheral surface of the ring portion and the facing surface of the case facing the ring portion, and the ring portion is fixed by the fixing member Is to make the irregularities coincide. That is, in order to suppress the rotation, various positions (surfaces) can be used as the opposing surface that forms the irregularities. For example , the internal gear that is one aspect of the invention of (5) described above can be used. It can also be provided on the inner peripheral surface of the ring portion as in a similar form. However, when it is formed on the inner peripheral surface, when adjusting the angle, once the ring portion is shifted to a position where the unevenness of the case portion (main body) is not formed, and after setting the angle in that state, You need to plug it in again. Therefore, as shown in (6), if the surface (side surface) orthogonal to the axis of the ring part is uneven, there is no such problem (the rotation is possible if the solid uneven engagement is released). preferable. The invention described in (6) is realized by the embodiment.
Although the rotation of the mounting bracket can be suppressed to some extent by the fixing member, the rotation can be more reliably suppressed by providing irregularities at appropriate positions. Moreover, although unevenness was continuously formed 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.

(7) The unevenness formed on the side surface orthogonal to the inner peripheral surface of the ring portion and at least a part of the facing surface of the case portion opposed thereto has an inclined surface inclined along the rotation direction of the ring portion. It is good to have a shape that it has. The shape constituting the inclined surface may be a flat surface (taper: triangular wave-shaped unevenness) as in the embodiment, may be appropriately curved (wave shape), or may be a spherical surface (hemispherical surface). It can take various forms. Since it is inclined along the rotation direction, even if the unevenness of each other fits to some extent, the fixing force to the ring part is weak (the tightening force between the main body and the fixing member is weak), and in the case of temporary fixing When a strong force is applied in the rotation direction, the rotation can overcome the mutual irregularities, that is, the angle can be adjusted. On the other hand, if the unevenness has a side wall extending in a direction orthogonal to the rotation direction, for example, a rectangular wave, it is difficult to adjust (angle adjustment in a state where the fitting is released). Is required).

(8) The installation surface of the switch formed on the surface of the case portion is flattened so that the field of view of the camera, which is one of the electronic components housed in the case portion, faces away from the installation surface. The camera may take a picture of the outside of the case portion . (9) In this case, it is more preferable that the flat surface and the field of view are set to be orthogonal 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 the front from the inside of the vehicle. However, 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 camera's field of view is directed to the opposite side of the flat surface. Since the orientation of the camera with respect to (surface) is known, the orientation of the camera can be estimated from the orientation of the installation surface. At this time, if the orientation of the camera is orthogonal to the flat surface as in the invention of (9), for example, if the installation surface is parallel to the vertical direction, the camera will face the horizontal direction. The direction can be estimated more easily. However, even if they are not necessarily orthogonal, there is no problem because the direction of the camera relative to the installation surface can be estimated.

(10) The GPS antenna built in the case section may be disposed obliquely upward with reference to a standard posture when installing the in-vehicle device in the vehicle . “Arranged obliquely upward” means that the GPS antenna surface is directed obliquely upward with respect to the basic posture of the main body (standard posture when the vehicle-mounted device is installed in the vehicle). In this way, for example, even if the orientation of the main body (for example, the orientation of the camera when the camera is incorporated) is downward, the GPS antenna can obtain good GPS reception sensitivity.

(11) the lead wires for supplying power to the electronic components mounted within the case portion, it is preferable to be performed from one side that intersects the axis of the rotation center of the case portion. The wiring may be pulled out by providing a jack and attaching / detaching the wiring to / from the jack as in the embodiment, or connecting the wiring directly to the case portion (main body) . In either case, if the wiring (power supply) is pulled out from the side surface, the wiring can be hidden in the rearview mirror, so that it looks beautiful.

(12) When an operation switch is arranged on a surface parallel to the rotation center axis of the case section, and a volume operation section for adjusting the volume of the built-in speaker is arranged on a side surface intersecting with the rotation center axis of the case section. Good. In this way, since it is possible to the front facing frequently used switches to the user, it makes the manipulation easy.

(13) the mounting bracket is provided on one end side of the shaft of the rotational center of the case portion, inside the casing section comprises a card slot for mounting a memory card for storing recorded data, the It is preferable that an outlet of the card slot provided in the case portion is set on an end surface opposite to the fixing bracket. This makes it easy to attach and remove a memory card such as an SD card to / from the card slot.

(14) The fixing member is attached to one side surface of the rotation center shaft of the case portion, and an opening portion is provided in a part thereof, and the side surface of the case portion located in the opening portion is connected to the outside. An interface may be provided. The opening corresponds to the “through hole 42” in the embodiment. In the embodiment, the interface corresponds to the DC jack 15 or the volume dial 23. Thus, when attaching the fixing member to the side surface of the case portion (main body) , by providing the opening portion, a part of the side surface of the case portion (main body) can be exposed to the outside from the opening portion. Therefore, by arranging an interface with the outside mounted in the case part (main body) in the exposed part , the operation target can be efficiently installed in a limited space of the case part (main body). . Further, by bringing the interface and the fixing member close to each other, it becomes easy for the user to pay attention to the state of the fixing member when operating the interface, and it is possible to check naturally and easily whether there is any looseness.

(15) The attachment member may be attached to the windshield . (16) Further, the mounting member may be arranged such that its mounting surface is inclined with respect to the diameter of the ring portion. (17) The case portion may be formed in a cylindrical shape, and the cylindrical axis may coincide with the rotation center of the case. (18) The on-vehicle device having each configuration described above can 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 mounted on the main body, the relative rotation angle relationship between the mounting member of the mounting bracket and the main body can be changed, and The configuration can handle different types of vehicles.

  Hereinafter, a preferred embodiment of a drive recorder according to the present invention will be described with reference to the accompanying drawings. First, the drive recorder according to the present embodiment has a configuration in which a cylindrical main body 10 is provided and a mounting bracket 30 is mounted on one end side in the axial direction of the main body 10.

  The main body 10 is configured by abutting a first case 11 and a second case 12 that are divided into two (half) at the 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 so that the outer dimensions are slightly smaller, and the one end portions 11a and 12a and the shaft of the main body are formed. A step is formed between the central portion in the direction. A triangular wave (sawtooth) tooth portion 17 is formed on the wall surface where the step is generated. Furthermore, a male screw 18 is formed on the outer peripheral surface of the front end side of the one end portions 11a, 12a of the first case 11 and the second case 12.

  The mounting bracket 30 is erected on the ring portion 31 having an inner diameter that substantially matches (slightly larger) the outer diameter of the one end portions 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 part 32. As shown in FIG. 5, the mounting plate 33 is disposed obliquely at a predetermined angle with respect to the diameter direction of the ring portion 31.

  Further, a tooth portion 34 is formed on one surface of the ring portion 31 (a surface facing the main body 10) over the entire circumference thereof. The teeth 34 are set to have the same size and shape so as to coincide with the teeth 17 formed on the main body 10. Further, 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 (the unformed region of the male screw 18) of the one end portions 11 a and 12 a 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 is set shorter than the width D2 up 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 an internal thread that matches the external thread 18 is formed on the inner peripheral surface 41 thereof. A circular through hole 42 is formed at the center of the nut member 40. Small semicircular convex portions 11d and 12d (small circular convex portions) of the main body are exposed to the outside from the through hole 42, and the operation target of the user such as the volume dial 23 and the DC jack 15 is exposed to the exposed portion of the convex portion. Things 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 to easily check whether the nut member 40 is loose as a result of attracting the user's attention during the operation. .

  As a result, when the ring portion 31 is attached to the one end portions 11a and 12a of the first case 11 and the second case 12, the ring portion 31 has one end of the first case 11 and the second case 12 with its central axis as the rotation center. It can be rotated forward and backward relative to the portions 11a and 12a. And rotation is suppressed by meshing | engaging the tooth part 17 provided in the main body 10, and the tooth part 34 provided in the ring part 31. FIG.

  On the other hand, in the state where the ring portion 31 is mounted on 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 projects outward from the ring portion 31. Therefore, the nut member 40 is attached to the protruding male screw 18. And the space | interval to the level | step-difference part in which the nut member 40 and the tooth | gear part 17 of the main body 10 were formed is narrowed by firmly fastening the internal thread of the nut member 40, and the external thread 18 of the main body 10, and the main body 10 and a nut. The ring portion 31 can be sandwiched between the member 40 with a predetermined force. When the teeth 17 and 34 are engaged with each other in this manner, the rotation of the ring portion 31 and thus the mounting bracket 30 is suppressed, and when the nut member 40 is loosened, the rotation is allowed. 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. That is, when a plane (direction) parallel to the joint surface of the first case 11 and the second case 12 is a basic vertical direction of the main body 10, an angle formed by the vertical direction and the mounting plate 33 of the mounting bracket 30 is defined. 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 is adhered and fixed to the windshield of the vehicle using the double-sided tape. Therefore, the drive recorder of this embodiment can be adjusted according to the angles (25 to 75 degrees) of various windshields. That is, although the mounting plate 33 is parallel to the angle of the windshield, as described above, the relative angle of the main body 10 with respect to the mounting plate 33 (mounting bracket 30) can be adjusted, so the angle of the mounting plate 33 (windshield) Regardless of whether the main body 10 is in the basic vertical direction, for example, it can be parallel to a vertical plane (with respect to the ground). Of course, the angle formed between the basic vertical direction of the main body 10 and the vertical plane with respect to the ground can be set to an appropriate angle. Therefore, it can be mounted on different types of vehicles with one drive recorder.

  Further, by firmly fastening the nut member 40, the tooth portion 17 of the main body 10 and the tooth portion 34 of the mounting bracket 30 are firmly meshed with each other and their rotation is reliably prevented. Even if an impact is applied, the orientation and orientation of the main body 10 can be maintained in the basic orientation when the drive recorder is attached to the windshield (unless the mounting plate 33 is peeled off from the windshield) and can be firmly fixed. it can.

  Furthermore, as shown in FIG. 3 etc., the packing 50 which consists of elastic bodies, such as rubber | gum, is arrange | positioned inside the nut member 40 (main body 10 side). The inner diameter of the packing 50 is set to be approximately the same as or slightly wider than the outer diameter of the male screw 18 of the main body 10, and the outer diameter of the packing 50 is set slightly 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 is substantially the same as the width D1 of the flat portion (the unformed region of the male screw 18) of the one end portions 11a and 12a of the first case 11 and the second case 12. In the state where the ring part 31 is mounted on the one end part 11a, 12a, the tip of the flat part of the one end part 11a, 12a and the end face of the ring part 31 on the nut member 40 side are substantially surface positions. One surface of the packing 50 can contact the main body 10 and the ring portion 31 beyond the male screw 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 each 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 good to provide the annular convex part which fits in the level | step-difference part between D * D1 with respect to a ring part.

  By additionally arranging the packing 50 as described above, it is possible to prevent loosening due to vibration, to prevent useless recording triggered by vibration as a drive recorder, and to record an accident video more reliably at the time of impact. Of course, this packing 50 is not necessarily provided.

  Next, an arrangement structure of each component mounted in the main body 10 and an externally exposed 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 from the opening 11b.

  The GPS antenna 14 is disposed at a predetermined angle with respect to the vertical direction of the main body 10 (surface (direction) parallel to the joint surface of the first case 11 and the second case 12), and is directed obliquely upward. (See FIG. 13 etc.). Thereby, for example, even when the field of view of the CCD camera 13 is set to face obliquely downward when mounted on a track or the like, good GPS reception sensitivity can be obtained.

  As shown in FIGS. 7, 8, etc., the DC jack 15 is arranged in parallel to the axial direction of the main body 10 and is exposed to one end side of the main body 10. That is, as shown in FIG. 1 etc., the window hole 11c is formed in the predetermined position of the end surface (side surface orthogonal to an axial direction) of the one end part 11a of the 1st case 11, and the DC jack 15 uses the window hole 11c. Exposed to the outside. By attaching a DC plug (not shown) attached to one end of a power cable connected to the cigar socket, for example, the drive recorder of the present embodiment can be supplied with power from the vehicle battery. And As described above, since the power cable is pulled out from the side surface of the main body 10, the power cable can be hidden in the rear view mirror by attaching the drive recorder to the side or near the rear view mirror, and it looks beautiful. be able to.

  Further, as shown in FIGS. 7 and 8, locking claws 12 c are provided at predetermined positions on the joint surface of the second case 12. On the joint surface of the first case 11, a recess for locking is formed at a position corresponding to the locking claw 12c. When the first and second cases 11 and 12 are brought into contact with each other, the locking claw 12c And the concave portion mesh with each other, positioning and preventing displacement (especially axial movement). Furthermore, small semicircular convex portions 11d and 12d are formed on the end surfaces (side surfaces orthogonal to the axial direction) of the one end portions 11a and 12a of the first and second cases 11 and 12, respectively. And in the state which faced the 1st, 2nd cases 11 and 12, both convex parts 11d and 12d are faced, and it becomes a small circular convex part. By fitting the annular stop member 16 to the convex portions 11d and 12d, the effect of preventing displacement due to vibration can be further enhanced. Further, when the nut member 40 is fastened, the convex portions 11d and 12d enter the through hole 42 of the nut member 40 and are exposed to the outside from the side surface in the axial direction.

  On the other hand, as shown in FIGS. 9 and 10, a man-machine interface such as a switch unit 20, a display unit 21, an SD card slot 22, a volume dial 23, and a control circuit are mounted on the second case 12 side. . The control circuit is a circuit for realizing the basic function of the drive recorder, and stores the video imaged by the CCD camera 13 or based on a detection signal from an impact detection sensor such as an acceleration sensor (not shown) based on the detection signal described above. Data such as captured images is stored in a nonvolatile memory. Although not shown, an output device such as a speaker is also mounted. From the speaker, for example, an operation sound in the switch unit 20 and various messages (guide, warning, etc.) are notified. The volume dial 23 is for adjusting the output level of the speaker. Furthermore, an electronic component / electronic circuit for realizing the functions of an acceleration sensor and other drive recorders for detecting a collision or the like is incorporated on the second case 12 side.

  Further, as shown in FIG. 11, the first case 11 and the second case 12 have flat surfaces 11e and 12e whose surfaces opposite to the bonding surfaces are parallel to the bonding surfaces. Therefore, both the flat surfaces 11e and 12e are set in 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 on the flat surface 11e), and the field of view of the CCD camera 13 is a flat surface. It is set to be in a direction orthogonal to 11e.

  On the other hand, the switch unit 20 and the display unit 21 are arranged on the flat surface 12 e of the second case 12. And when attaching a drive recorder to a windshield, it installs so that the 1st case 11 (CCD camera 13) may face the front of a vehicle, and the 2nd case 12 may face the inside of a 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 this embodiment, since the flat surface 11e of the first case 11 and the flat surface 12e of the second case 12 are set to be parallel, the flat surface 12e of the second case 12 facing the vehicle interior. Is the same as the orientation of the flat surface 11e of the first case 11 and then the orientation of the CCD camera 13, so the orientation of the CCD camera 13 is estimated by looking at the orientation of the switch unit 20 and the display unit 21 (flat surface 12e). Therefore, the orientation of the CCD camera 13 can be easily adjusted.

  Further, the volume dial 23 mounted in the second case 12 is disposed on the one end portion 12a side of the second case 12, and is formed in a small semicircular shape formed on the end surface (side surface orthogonal to the axial direction) of the one end portion 12a. A part of the volume dial 23 protrudes to the outside through a vertical slit 12f provided on the convex portion 12d, and can be rotated. Furthermore, the SD card slot 22 is disposed on the side surface opposite to the one end 12a of the second case 12 (see FIG. 11 and the like). As described above, among the man-machine interfaces, those that are frequently used such as the switch unit 20 are arranged on the front surface, and those that are not frequently used such as the volume dial 23 and the SD card slot 22 are arranged on the side surface. , Operability is improved.
