Description

  The present invention relates to an in-vehicle display device in which a display unit is fixed to a support member so that the display unit is arranged on the front surface.

  2. Description of the Related Art Conventionally, there is an in-vehicle display device in which a display unit composed of a liquid crystal display element or the like is arranged on the front surface of the device body. This in-vehicle display device is mounted at a predetermined position of an instrument panel that is highly visible for a vehicle occupant. Therefore, there is a possibility that the occupant may collide with the front surface of the apparatus at the time of sudden braking or collision. Therefore, it is necessary to prevent the scattering of the glass and the exposure of the sharp edge that occur at the time of the collision, thereby ensuring the safety of the occupant. For example, Patent Document 1 is disclosed as an in-vehicle display device that buffers such an impact at the time of a collision.

  This in-vehicle display device is configured to position and fix a metal case (first support member) containing a liquid crystal display element or the like to a chassis (second support member) by a holding metal fitting (buckling member). One end of the holding metal fitting is connected to the metal case, extends obliquely rearward from the one end, and is screwed to the chassis via a concave mounting groove provided at the other end.

When an external force exceeding a predetermined value is applied to the display unit from the front side, the holding bracket buckles and the external force is buffered, and the display unit is pushed backward in the apparatus main body. When a force close to the buckling load is applied to the other end of the holding metal, the holding metal slides against the chassis until the bottom of the concave portion of the attachment groove hits the attachment screw, and the external force is buffered. Thereby, even if a passenger | crew collides with the apparatus front surface, scattering of glass and exposure of a sharp edge are prevented.

  However, in the case of the on-vehicle display device described above, the display unit is fixed to the chassis via a holding metal fitting as a buckling member. In other words, the buckling portion and the portion (mounting groove) for fixing the display portion to the chassis are linearly connected. Here, since buckling deformation has a relatively high buckling load at which buckling is started, if the buckling load is to be adjusted low, it is necessary to reduce the rigidity of the holding metal fitting. However, in this case, since the display unit is held by a low-rigidity holding bracket, the holding power of the display unit is reduced.

  Further, the above-described holding metal fitting is bent at an angle larger than 90 degrees, and for example, there is a possibility that a processing error due to bending may occur in the holding metal fittings provided on the left and right sides of the metal case.

  Furthermore, the display unit can be fixed to the chassis only by inserting a screw into the concave mounting groove and tightening, so that there is a risk that the holding brackets provided on the left and right sides of the metal case will be displaced.

  Therefore, the display unit is not positioned and fixed at a predetermined position with respect to the chassis, and the screen position accuracy of the display unit with respect to an operation panel such as an audio / air conditioner disposed around the display unit is lowered (a gap or the like is generated and the appearance is improved). There is a risk of a bad condition).

  In view of the above problems, an object of the present invention is to provide an in-vehicle display device capable of buffering external force and ensuring the screen position accuracy of a display unit.

The vehicle display device according to claim 1 in order to achieve the above object, so that the display unit on the front is disposed, as a vehicle-mounted display device formed by fixing the display unit to the support member, the display A positioning part that positions at least the position of the display part in the front-rear direction with respect to the support member by a part of the part coming into contact with the support member; and the position of the display part in the front-rear direction with respect to the support member A fixed portion that fixes the display unit to the support member in a state where the display unit is positioned , and the positioning unit projects from the display unit substantially perpendicularly to the direction in which an external force is applied; A support portion that extends from the support member substantially perpendicularly to the front surface of the display portion and supports the rear surface of the cantilever portion, and the cantilever portion is provided from the side surface to the rear surface of the display portion.

Thus, according to the in-vehicle display device of the present invention, when an external force of a predetermined value or more is applied from the front surface side to the rear surface side of the display portion, the cantilever portion is pushed into the support portion and is bent and deformed. The external force can be buffered.
The external force acts on the cantilever portion, the support portion, and the fixed portion in parallel. Therefore, the display unit can be fixed to the support member by the fixing unit regardless of the balance between the yield load and the rigidity at which the plastic bending deformation of the cantilever part is started. improves. That is, it is possible to ensure the screen position accuracy of the display unit with respect to an operation panel such as an audio / air conditioner disposed around the display unit.
Further, the yield load at which plastic bending deformation of the cantilever portion is started is determined by the width of the cantilever portion and the length of the cantilever portion up to the position supported by the support portion. When the display unit has a deletion part, the length of the cantilever part protruding from the rear side end of the deletion part can be adjusted by adjusting the size of the deletion part on the rear surface side. . Therefore, even if the cantilever portion is supported by the support portion at a position in contact with the side surface of the display portion, the above-described length adjustment is possible, so that the yield load can be adjusted.
In addition, since the deletion portion is provided from the side surface to the rear surface of the display portion so as not to prevent the deformation of the cantilever portion, the external force can be buffered by the bending deformation of the cantilever portion.
Further, since the cantilever portion is not bent and is provided along the rear surface of the display portion, the processing error is small. Therefore, the position accuracy of the display unit in the front-rear direction with respect to the support member is improved, and the screen position accuracy of the display unit is improved.

In the configuration according to claim 1, for example, as described in claim 2, while extending substantially perpendicularly from the support member in the front direction of the display unit, by contacting the side surface of the cantilever part, It is good also as providing the extension part which positions the position of the up-down direction of the said display part with respect to the said supporting member.
According to such a configuration, since the extending portion of the support member and the cantilever beam portion that determines the position in the front-rear direction can contact each other, positioning in the vertical direction can be performed, thereby reducing the number of parts (or simplifying the device structure) )can do.

In order to achieve the above object, in the invention according to claim 3, the display is provided as an in-vehicle display device in which the display unit is fixed to a support member so that the display unit is disposed on the front surface.

By supporting the rear surface of the cantilever part vertically while extending from the support member substantially perpendicularly to the front surface direction of the display part, the cantilever part protrudes from the display part. Said A support portion for positioning a front-rear direction position of the display portion; and the display with respect to the support member by extending from the support member substantially perpendicularly to the front surface direction of the display portion and contacting a side surface of the cantilever portion And an extension part for positioning the vertical position of the part, and when an external force of a predetermined value or more is applied from the front side to the rear side of the display part, the positioning part and the fixing part are respectively parallel to the positioning part. While an external force is applied, the cantilever portion is pushed into the support portion to be bent and deformed to buffer the external force.

Thus, according to the in-vehicle display device of the present invention, when an external force of a predetermined value or more is applied from the front surface side to the rear surface side of the display portion, the cantilever portion is pushed into the support portion and is bent and deformed. Therefore, the external force can be buffered.
The external force acts on the cantilever portion, the support portion, and the fixed portion in parallel. Therefore, the display unit can be fixed to the support member by the fixing unit regardless of the balance between the yield load and the rigidity at which the plastic bending deformation of the cantilever part is started. improves. That is, it is possible to ensure the screen position accuracy of the display unit with respect to an operation panel such as an audio / air conditioner disposed around the display unit.
In addition, since the extending portion of the support member is in contact with the cantilever portion that determines the position in the front-rear direction, positioning in the vertical direction can be performed, so that the number of parts can be reduced (or the device structure can be simplified). it can.

It is preferable.
The yield load at which plastic bending deformation of the cantilever portion is started is determined by the width of the cantilever portion and the length of the cantilever portion up to the position supported by the support portion. When the display unit has a deletion part, the length of the cantilever part protruding from the rear side end of the deletion part can be adjusted by adjusting the size of the deletion part on the rear surface side. . Therefore, even if the cantilever portion is supported by the support portion at a position in contact with the side surface of the display portion, the above-described length adjustment is possible, so that the yield load can be adjusted.
In addition, since the deletion portion is provided from the side surface to the rear surface of the display portion so as not to prevent the deformation of the cantilever portion, the external force can be buffered by the bending deformation of the cantilever portion.
Further, since the cantilever portion is not bent and is provided along the rear surface of the display portion, the processing error is small. Therefore, the position accuracy of the display unit in the front-rear direction with respect to the support member is improved, and the screen position accuracy of the display unit is improved.

As described above, the support portion and the extension portion, both of which are provided on the support member, are integrally provided using the same material, so that the number of parts can be reduced (or the device structure can be simplified). In addition, when the support portion and the extension portion are attached to the support member by welding or the like, by reducing the number of parts, the attachment error can be reduced and the position accuracy of the display portion with respect to the support member can be improved. .

In the configuration according to any one of claims 1 to 5, for example, as in claim 6, the fixing portion is deformed when the cantilever portion is pushed into the support portion and bent. It is preferable to release the fixing between the display unit and the support member.
In this way, when the cantilever part is pushed into the support part and bent and deformed, if the display part and the support member are released from the fixed state, the display part can move in the rear direction, The beam portion can be deformed more greatly.

In particular, when three or more locations are provided, positioning in the front-rear direction is stable, so that the screen position accuracy of the display unit with respect to the operation panel can be improved.

Further, the display unit may be fixed to, for example, a chassis of a vehicle as a support member. However, as shown in claim 10, the display unit is fixed to a housing as a support member and then assembled to the vehicle. There may be. In this case, since the operation panel can be fixed to the housing, it is easy to position the operation panel with respect to the display unit.

Further, when an external force of a predetermined value or more is applied, the cantilever portion is pushed into the support portion and is bent and deformed, so that the external force can be buffered.

In the configuration according to claim 11 or 12, as described in claim 13, for example, the cantilever portion is formed from the rear surface side end portion of the deletion portion provided from the side surface to the rear surface of the display portion. The deletion part is larger than the cantilever part so that the cantilever part does not contact the display part when the cantilever part is bent and deformed. It was decided that it was provided.
The yield load at which plastic bending deformation of the cantilever portion is started is determined by the width of the cantilever portion and the length of the cantilever portion up to a position supported by a part of the support member. When the display unit has a deletion part, the length of the cantilever part protruding from the rear side end of the deletion part can be adjusted by adjusting the size of the deletion part on the rear surface side. . Therefore, even if the cantilever portion is supported by a part of the support member at a position in contact with the side surface of the display portion, the above-described length adjustment is possible, so that the yield load can be adjusted. it can.
In addition, since the deletion portion is provided from the side surface to the rear surface of the display portion so as not to prevent the deformation of the cantilever portion, the external force can be buffered by the bending deformation of the cantilever portion.
Further, since the cantilever portion is not bent and is provided along the rear surface of the display portion, the processing error is small. Therefore, the vertical position accuracy of the display unit with respect to the support member is improved, and the screen position accuracy of the display unit is improved.

In the configuration according to any one of claims 11 to 13, for example, as described in claim 14, the fixing portion is bent and deformed by the cantilever portion being pushed into a part of the support member. At this time, it is preferable to release the fixation between the display unit and a part of the support member.
In this way, when the cantilever part is pushed into a part of the support member and bent and deformed, if the display part and the support member are released from the fixed state, the display part can move in the rear surface direction. The cantilever portion can be deformed more greatly. Therefore, the external force can be further buffered.

In the configuration described in claim 14, for example, as in claim 15, the fixing portion is substantially parallel to the front-rear direction, the display portion portion, and the support member approximately in the front direction of the display portion. In the mating surface with the extending portion that extends vertically, the screw hole formed in both of them, and a fixing screw inserted into the screw hole, at least one of the screw holes formed in both the above, It is preferable that the fixing screw has a length capable of moving in the screw hole along the front-rear direction.
As a result, when the cantilever portion is bent and deformed, the display portion moves in the rearward direction within the range of the screw hole, so that the external force is further buffered.

In the configuration according to claim 15, for example, as described in claim 16, the extension portion contacts a side surface of the display portion, thereby positioning a position of the display portion in the left-right direction with respect to the support member. It is preferable.
Thus, the extension part of the supporting member having the screw hole as the fixing part performs the positioning in the left-right direction, so that the number of parts can be reduced (or the device structure can be simplified).

In addition, as described in claim 17, it is preferable to provide a plurality of positioning portions and fixing portions according to any one of claims 11 to 16 because the positional accuracy of the display portion with respect to the support member is improved.

Further, the display unit may be fixed to, for example, a chassis of a vehicle as a support member. However, as shown in claim 18, the display unit is fixed to a housing as a support member and then assembled to the vehicle. There may be. In this case, since the operation panel can be fixed to the housing, it is easy to position the operation panel with respect to the display unit.

Further, the cantilever portion 26 is not integrally provided using the same material as that of the lower case 22 and may be fixed to the lower case 22 by welding or the like as a separate part. However, in the case of another part, the number of parts increases and an installation error occurs. Therefore, in order to reduce the position accuracy of the display unit 20 and the number of parts, it is preferable that the parts are provided integrally with the lower case 22.

  Here, the yield load at which plastic bending deformation of the cantilever portion 26 is started is supported by the width D of the cantilever portion 26 and the support portion of the casing 30 described later from the bottom end portion (see FIG.

In addition, when an external force of a predetermined value or more is applied to the throttle portion of the screw hole 32c, the cantilever portion 26 is bent and deformed, and the fixing screw passes through the throttle portion of the screw hole 32c. The display unit 20 is provided so as to be moved in the rear surface direction of the screw hole 32c.

  In addition, the moving amount | distance of the display part 20 is determined by the length of the front-back direction of the screw hole 32c. Therefore, in the present embodiment, even if the fixing screw moves to the rear end of the screw hole 32c, the screw so that the rear surface of the display unit 20 does not come into contact with the rear case 30 (and the case 30 mounting component). The length of the hole 32c is set.

  Here, in this embodiment, the support part 32a as a positioning part for positioning in the front-rear direction and the extending part 32b having a screw hole 32c as a fixing part are arranged in parallel as shown in FIG. Is provided. The state of being provided in parallel is not a linear positional relationship in which an external force is transmitted to the extension part 32b (screw hole 32c as a fixing part) through the support part 32a, but to the support part 32a and the extension part 32b. A positional relationship where external force acts in parallel. Furthermore, in this embodiment, it is set as the structure by which the cantilever part 26 provided in the display part 20 side among the positioning parts is bending-deformed.

  Therefore, since the extension part 32b can set rigidity irrespective of the cantilever part 26, the positional accuracy of the display part 20 with respect to the housing | casing 30 improves compared with the past. That is, the screen position accuracy of the display unit 20 with respect to the operation panel 40 such as an audio / air-conditioner disposed around the display unit 20 can be ensured. In the present embodiment, among the positioning parts for positioning in the front-rear direction, the cantilever part 26 of the display unit 20 is bent and deformed. However, the support part 32a of the housing 30 is bent and deformed. Also good. Even in that case, external force acts in parallel between the support portion 32a as the positioning portion and the extending portion 32b having the screw hole 32c as the fixing portion, so that the screen position accuracy of the display portion 20 can be ensured.

  Further, the extending portion 32 b can be positioned in the left-right direction of the display unit 20 with respect to the housing 30 by contacting the lower case side surface 22 c which is the side surface of the display unit 20 on the inner surface. That is, the extended portion 32 b and the lower case side surface 22 c are positioning portions that position the position of the display unit 20 in the left-right direction with respect to the housing 30. In the present embodiment, the display unit 20 is disposed between a total of four projecting portions 32 provided at two locations on the left and right, and the side surface 22c of the lower case 22 is provided on at least one inner surface of the extended portion 32b. Are brought into contact with each other and positioning in the left-right direction is performed.

  Furthermore, the extension part 32b can position the vertical position of the display unit 20 with respect to the housing 30 by contacting the side surface of the cantilever part 26 on the side surface of the support part 32a. In other words, the extending portion 32 b and the cantilever portion 26 are positioning portions that position the vertical position of the display unit 20 with respect to the housing 30. In the present embodiment, among the protrusions 32 provided at the left and right two positions, at least the side surface of the cantilever part 26 is locked to the side surface of the extension part 32b of the upper protrusion part 32, thereby The vertical positioning of the display unit 20 with respect to the body 30 is performed.

  Thus, the extending part 32b in this embodiment also serves as a positioning part in the vertical direction and the horizontal direction while having the screw hole 32c as the fixing part. Therefore, the apparatus configuration can be simplified (or the number of parts can be reduced when the extending part 32b is a separate part from the housing 30). In addition, the extending part 32b having the screw hole 32c as a fixing part, and at least one of the vertical positioning part and the horizontal position part may be provided as separate parts in the housing 30. However, in order to reduce the positional accuracy of the display unit 20 and the number of parts, which will be described later, as described above, it is preferable that the extending portion 32b also serves as at least one of the positioning unit in the vertical direction and the horizontal direction.

  Moreover, the protrusion part 32 in this embodiment has the notch part 32d over the predetermined range from the boundary with the base 31, as shown in FIG.3 (b). By adjusting the size of the notch 32d, the rigidity of the protrusion 32 can be adjusted.

  The in-vehicle display device 10 is formed by positioning the display unit 20 configured in this manner on the housing 30 and screwing it.

  Next, positioning of the display unit 20 with respect to the housing 30 will be described with reference to FIGS. 4A and 4B are diagrams for explaining positioning of the display unit 20 to the housing 30, where FIG. 4A is a plan view viewed from the front of the apparatus 10, FIG. 4B is a side view, and FIG. It is an expansion perspective view around a fixed part. 4A, only the bottom surface of the lower case 22 (including the cantilever portion 26 protruding along the bottom surface) of the display unit 20 is illustrated for the sake of convenience.

  First, the display unit 20 is positioned with respect to the housing 30. As shown in FIGS. 4A to 4C, the rear surface of the cantilever part 26 of the display unit 20 is brought into contact with the tip of the support part 32 a of the protrusion part 32 of the housing 30, and The side surface of the cantilever portion 26 is brought into contact with the side surface of the extension portion 32 b, and the side surface 22 c of the lower case 22 constituting the display unit 20 is brought into contact with the inner surface of the extension portion 32 b, so To position the display unit 20.

  As described above, the vertical, horizontal, and front-rear direction positions of the display unit 20 with respect to the housing 30 are collectively determined, so that the structure of the in-vehicle display device 10 can be simplified. In addition, when the cantilever part 26 and the protrusion part 32 are separate parts from the lower case 22 and the housing 30, respectively, the number of parts can be reduced. When the number of parts is small, positional deviation due to part tolerances and mounting errors can be reduced, so that the positional accuracy of the display unit 20 is improved.

  Further, in the present embodiment, the cantilever portion 26 is integrally provided along the bottom surface of the lower case 22, so that the portion involved in positioning in the front-rear direction and the up-down direction is not bent, The position accuracy of the display unit 20 is improved. Further, since the support portion 32a and the extension portion 32b are also bent substantially perpendicularly to the base portion 31 of the housing 30, the processing error is smaller than those bent at 90 degrees or more, and the display portion 20 The position accuracy of the is improved.

  Since the screw hole provided in the side surface 22c of the lower case 22 and one end of the screw hole 32c provided in the extending part 32b overlap with the display unit 20 positioned in the housing 30, the fixing screw 50 Insert and fasten. Thereby, the display part 20 is fixed to the housing | casing 30, and the vehicle-mounted display apparatus 10 is formed. In this case, since the extending part 32b positions the vertical and horizontal positions of the display unit 20 with respect to the housing 30, it can be fixed to the housing 30 while positioning the display unit 20.

  When an external force of a predetermined value (yield load of the cantilever portion 26) or more is applied from the front side of the display unit 20 to the rear side of the display device 10 thus formed, the direction in which the external force is applied The cantilever part 26 for positioning in the front-rear direction, which is the same direction as the (front-rear direction), is bent and deformed with the support part 32a of the protruding part 32 as a fulcrum.

  Further, with the bending deformation of the cantilever portion 26, the fixation between the display portion 20 and the housing 30 is released, and the fixing screw 50 moves in the rearward direction within the range of the length of the screw hole 32c provided in the extending portion 32b. Is done. That is, the display unit 20 is pushed into the rear side (the housing 30 side).

  Therefore, since the in-vehicle display device 10 according to the present embodiment can buffer the applied external force, even if an occupant collides with the in-vehicle display device 10 on the front side of the display unit 20, the scattering of the glass or the sharp edge Can be prevented, and passenger safety can be ensured.

  Further, in the case of a structure that absorbs an impact by a conventional buckling deformation, since the buckling load is relatively high, it is difficult to adjust the balance between the buckling load and the rigidity, and the positional accuracy of the display unit 20 with respect to the housing 30 is obtained. It was difficult. However, the in-vehicle display device 10 according to the present embodiment is parallel to the cantilever portion 26 and the support portion 32a in which the applied external force is positioned in the front-rear direction, and the extension portion 32b including the screw hole 32c as the fixing portion. The cantilever portion 26 is bent and deformed. Accordingly, the rigidity of the extending portion 32b that holds the display unit 20 on the front side of the housing 30 can be set regardless of the cantilever portion 26 (the positioning portion in the front-rear direction to be bent and deformed). The position accuracy of the display unit 20 with respect to 30 is improved. That is, the screen position accuracy of the display unit 20 with respect to the operation panel 40 such as an audio / air-conditioner disposed around the display unit 20 can be ensured.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made.

  In the present embodiment, a support portion 32a as a positioning portion for positioning in the front-rear direction, and an extension portion 32b having a screw hole 32c as a fixing portion and holding the display portion 20 on the front side of the housing 30, An example in which they are integrally provided in parallel is shown. However, as shown in FIG. 5, the support part 32a and the extension part 32b may be provided separately. However, if they are provided separately, the number of parts increases or the apparatus configuration becomes complicated. In particular, when the support portion 32a and the extension portion 32b are attached to the base portion 31 of the housing 30 by welding or the like, the attachment error increases as the number of parts increases. Therefore, as shown in this embodiment, it is preferable that the support part 32a and the extension part 32b are provided integrally. FIG. 5 is a plan view showing a modified example of the protrusion 32.

  Further, in the present embodiment, the cantilever portion 26 positions the front and rear direction and the vertical direction, and the extending portion 32b including the screw hole 32c as a fixing portion positions the vertical and left and right positions. showed that. However, the cantilever part 26 and the support part 32a of the protrusion part 32 are positioned only in the front-rear direction, and a positioning part for positioning in the vertical direction, a positioning part for positioning in the left-right direction, and a fixing part are provided separately. It may be. However, if they are provided separately, the number of parts increases or the apparatus configuration becomes complicated. Note that it is preferable to provide a plurality of positioning portions and a plurality of fixing portions because the positional accuracy of the display unit 20 is improved.

  Moreover, in this embodiment, the cantilever part 26 showed the example which protrudes from the bottom face side edge part of the deletion part 27 provided in the lower case 22. As shown in FIG. However, the cantilever portion 26 may have a structure that protrudes from the display portion 20 substantially perpendicular to the direction in which the external force is applied. For example, a structure that protrudes from the side surface 22c of the lower case 22 or a structure that protrudes from the end of the deletion portion 27 into the deletion portion 27 in the deletion portion 27 provided only on the bottom surface of the lower case 22 is possible. It may be. In addition, the display unit 20 does not have the deletion unit 27 at least on the bottom side, and the cantilever part 26 protrudes from the bottom side end portion (the bottom corner of the lower case 22) of the display unit 20. Also good. However, when the protruding portion 32 is provided in a flat plate shape, the cantilever portion 26 cannot secure a sufficient length from the bottom side end portion of the lower case 22 to the support position by the support portion 32a, and the length thereof is also It cannot be adjusted. Therefore, it is preferable that the display unit 20 includes the deletion unit 27, and the cantilever part 26 has a structure that protrudes from the bottom end of the deletion unit 27 along the rear surface of the display unit 20.

  Further, in the present embodiment, an example in which the cantilever portion 26 is bent and deformed as a structure for buffering an external force applied from the front surface of the display unit 20 to the rear surface direction is shown. However, when the external force cannot be fully buffered even if the cantilever portion 26 is bent and deformed, the protruding portion 32 on the housing 30 side may be buckled and deformed to buffer the external force. As shown in FIG. 3B, since the protrusion 32 has a notch 32d, the buckling load and the rigidity of the protrusion 32 are balanced by adjusting the size of the notch 32d. be able to.

  In the present embodiment, the fixing portion includes a screw hole 32 c provided in the extending portion 32 b of the housing 30, a screw hole provided in the lower case side surface 22 c of the display unit 20, and a fixing screw inserted into both of them. 50, the display unit 20 is fixed to the housing 30 by screw fastening, and when the cantilever part 26 is bent and deformed, the fixing screw moves within the range of the screw hole 32c, and the display unit 20 An example in which is moved in the rear direction is shown. However, the method of fixing the display unit 20 to the housing 30 is not limited to screw fastening. When the cantilever portion 26 is bent and deformed, the display unit 20 and the housing 30 are not fixed. However, the display unit 20 does not necessarily have to move in the rear surface direction. When the display unit 20 does not move in the rear surface direction, the display unit 20 may be fixed to the housing 30 by, for example, claw fitting. However, when the cantilever portion 26 is bent and deformed, the impact can be further buffered if the display portion 20 moves in the rear surface direction.

  In the present embodiment, an example in which the display unit 20 is fixed to the housing 30 as a support member has been described. However, the support member is not limited to the housing 30 and may be, for example, a vehicle chassis. good. However, when the display unit 20 and the operation panel 40 are fixed to the housing 30, the operation panel 40 can be easily positioned with respect to the display unit 20.
