2. Description of the Related Art FIG. 1 shows a conventional reflection type display device for a vehicle.
9 is known. This reflective display device 1 for a vehicle has a substrate 3 below a rear end wall 2a in a substantially box-shaped apparatus main body 2 having an opening 2b above a rear end wall 2a on the driver's seat side.
A display device 4 such as a fluorescent display tube (VFD) is attached via such a device. The opening 2b of the apparatus main body 2 is covered with a cover glass 5 or the like. Further, a flat or spherical reflecting plate 6 is attached above the front end wall 2c facing the opening 2b of the apparatus main body 2.

The display image S from the display surface 4a of the display 4 facing the front windshield side of the vehicle is reflected by the reflector 6 to the driver's seat side. It can be visually recognized as.

[0004]

However, in the conventional reflection type display device 1 for a vehicle, the display 4 and the reflection plate 6 are not provided.
Are fixed at predetermined positions in the apparatus main body 2, respectively, and therefore, the opening 2 of the apparatus main body 2 varies depending on the driver's visual recognition position (eye height) due to the difference in the driver's physique and driving posture.
The display center of the display image S of the display device 4 is vertically displaced in the visual field range G in b, and the width of the black background around the display image S varies vertically and deviates, deteriorating the display quality. That is, as shown by reference numeral H in FIG. 19, when a driver with a high line of sight looks at the opening 2b of the apparatus main body 2 from above, as shown in FIG. The display image S is seen to be offset above the visual field range H of FIG.
As shown by the symbol L in FIG. 9, when a driver whose line of sight is low looks at the opening 2 b of the apparatus main body 2 from below, FIG.
As shown in (b), the display image S was seen to be offset below the visual field range G in the opening 2b.

Accordingly, the present invention has been made to solve the above-mentioned problems, and a display image of a display device is provided so as to correspond to each driver's eye position (viewing position) having a different driving posture and physique. It is an object of the present invention to provide a reflective display device for a vehicle that can easily adjust the display position of the vehicle to an optimum position.

[0006]

According to a first aspect of the present invention, a display image of a display facing a front windshield of a vehicle is reflected toward a driver's seat by a reflector, and the display image is converted from the driver's seat to a virtual image. In the reflection type display device for a vehicle, which is made visible, the display is provided below the one end in a substantially box-shaped device main body having an opening at an upper end on the driver's seat side, and the reflection plate is provided on the device main body. On one end side of the main body of the apparatus, an adjusting screw means is rotatably supported via an operating means, and the bracket is screwed to the adjusting screw means. The display is movable vertically.

[0007] In this reflective display device for a vehicle, the display moves in the vertical direction via the adjusting screw means which is turned by the operation of the operating means and the bracket which is screwed to the adjusting screw means. The display position of the display image on the display device is easily adjusted to the optimum position in accordance with the position of each driver's eye, which differs from each other.

According to a second aspect of the present invention, there is provided a vehicle for a vehicle in which a display image of a display facing a front windshield side of a vehicle is reflected toward a driver's seat side by a reflector, and the display image is visually recognized as a virtual image from the driver's seat. In the reflective display device, the display is provided below the one end in a substantially box-shaped device main body having an opening at one upper end on the driver's seat side, and the reflector is opposed to the opening of the device main body. A pinion is rotatably supported on one end side of the apparatus main body via operating means, and the indicator is movable vertically in a rack engaged with the pinion. It is characterized by.

In this reflection type display device for a vehicle, the display device moves vertically through a pinion that rotates by operating the operation means and a rack that meshes with the pinion. The display position of the display image on the display is easily adjusted to the optimum position according to the position of the driver's eye.

According to a third aspect of the present invention, there is provided a vehicle for a vehicle in which a display image of a display facing a front windshield side of a vehicle is reflected toward a driver's seat by a reflection plate, and the display image is made visible from the driver's seat as a virtual image. In the reflective display device, the display is provided below the one end in a substantially box-shaped device main body having an opening at one upper end on the driver's seat side, and the reflector is opposed to the opening of the device main body.

The display 116 attached to the side can be moved between the case 112 and the cover 113 covering the opening 112a of the case 112, so that the driving posture, the physique and the like can be adjusted to the viewing position of each driver, which is different from each other. The display position of the display image on the display device 116 can be easily adjusted to the optimum position. This adjustment position is the tip 131 of the slide lever 131.
The locking between the side a and the row of round holes 112h at a predetermined position of the case 112 ensures that the case 112 is securely locked and does not shift. Also,
Since only the moment in the moving direction with respect to the support shaft 115b acts on the display 116, the backlash due to this moment is reduced as shown in FIG.
Is easily and reliably absorbed by the engagement between the conical tapered surface-shaped tip 131a and the row of round holes 112h of the case 112, and the chatter of the intermediate cover 115 and the like due to the vibration of the vehicle is suppressed reliably and at low cost, and the image distortion. And vehicle interior noise can be reduced. Further, since the virtual image display position adjusting mechanism B functions as a lock mechanism, the overall structure can be simplified and the cost can be further reduced.

Although the VFD is used as the display according to each of the fourth to sixth embodiments, the display is not limited to the VFD, but may be an LCD or an LED. Also, the sixth
In the embodiment, the side walls 112g, 11
Round hole array 112 in which round holes are continuous as a plurality of engaging portions in 2 g
h is formed, as shown in FIG. 18 (a), a diamond-shaped hole array 112m in which diamond-shaped holes are continuous, or as shown in FIG. 18 (b), a plurality of round holes 112n are separated by a predetermined distance in the vertical direction. It may be formed. Further, the plurality of engaging portions is not limited to the hole shape, and may be a concave shape (hole shape).
