Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a display device suitable for displaying the movement of a driving body, and in particular, the present invention relates to a display device suitable for displaying the movement of a driving body, and in particular, the present invention relates to a display device suitable for displaying the movement of a driving body, and in particular, the forward position and left/right turning position of an automobile, airplane, etc. The present invention relates to a display device that displays.

(Prior Art) For example, conventional so-called graphic display devices that display the forward movement state and left/right turning state of an automobile are shown in FIGS. 9 to 12.
As shown in the figure. As shown in FIG. 10, this display device consists of a wiring board 1, a mouth-shaped smoked glass 2 attached to the wiring board 1, and a front plate 3 made of transparent acrylic resin attached to the outer surface of the smoked glass 2. Toko's top plate 3
It is provided with a back plate 4 made of transparent resin arranged on the inner surface of the smoked glass 2 so as to face each other, and a plurality of LED chips 5 arranged on the inner surface of the smoked glass 2. A car body frame 6 as shown in FIG. 9(d) is printed on the surface of the top plate 3, and a car body frame 6 as shown in FIGS. 11 and 12 is printed on the surface of the back plate 4 opposite to the top plate. A plurality of display sections 7 are provided. As is known, this display section 7 has a black opaque printed layer 8.
formed by handling. This display section 7 displays the forward movement of the vehicle body and the left/right turning state.

The LED chips 5 are arranged facing each display section 7. Note that the reference numeral 9 does not indicate the housing X of the LED chip 5.

Generally, this housing 9 is made of non-transparent white resin. In such a display device, a desired display section, for example, a leftward turning state or a rightward turning state of the vehicle body, is selectively displayed by selectively emitting light from a plurality of LED chips.

(Example of display mode; Figures 9(a>-(C)) (Problems to be solved by the invention) However, in the prior art as described above, multiple LED chips are required for each display section. Since LED chips are required and these LED chips are caused to selectively emit light, the display device becomes large in size and is inevitably expensive.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the problems of the prior art as described above, the present invention provides a drivable display body having a display portion of a drive body to display a display, and a driveable display body having a display portion of a drive body to display the display. This device is provided with a drive means for driving the body and a control means for controlling the drive means.

(Operation) The control means is sensitive to the movement of the driving body and controls the driving means so that the driving means drives the display body in accordance with the movement of the driving body.

(Example) Hereinafter, an example in which the present invention is applied to a graphic display device for an automobile will be described in detail with reference to FIGS. 1 to 8.

Referring to FIGS. 1 and 2, a display device according to the invention is shown, which includes a casing 10 and a display body 11 disposed within the casing 10. FIG. The casing 10 has a window hole 12 on the front surface. Furthermore, a frame body 1 is provided on the front surface of the casing 10 so as to surround the window hole 12.
3 is installed. The front surface of this frame 13 is formed from a glass plate 14. There is a display board 1 inside the window hole 12.
5 is arranged, and this display board 15 is fixed around the window hole 12 by, for example, heat welding. As shown in FIG. 5, the display board 15 is provided with, for example, a black cross-shaped reference line 16.

The display body 11 is arranged behind this display board 15 (see FIG. 2), and this display body 11 is driven by a driving means 17. In the illustrated embodiment, the display body 11 consists of a circular plate as shown in FIG.

It is adapted to be rotated by a driving means.

This display body 11 is provided with a display section 18 of a driving body to be displayed, which in this embodiment is a vehicle body frame of an automobile. As shown in FIG. 4, this body frame is formed by a translucent white layer 20 on the main body 19 of the display body 11 and an opaque black layer 21 provided on the translucent white layer 20. .

The drive means 17 is composed of a motor, a cross-coil type movement, etc. In the illustrated embodiment, the drive means 17 is attached to a wiring board 22, and this wiring board 22 is connected to the casing 10.
It is fixed to with screws 23.

Connected to the drive means 17 are control means 24, which consist, for example, of current generation means arranged on the shaft 25' of a steering wheel 25 of a motor vehicle. This current generating means is, for example, a torque motor that generates a current according to the rotation angle of the steering wheel 25.

This control means 24 generates a current according to the rotation of the steering wheel 25 and sends this current to the drive means 17.
Therefore, this driving means 17 rotates the display body 11 in accordance with the rotation of the steering wheel 25. This means that when the vehicle body turns left or right, the display body 11 rotates counterclockwise or clockwise in accordance with the turn. Figure 7 shows that when the vehicle turns left, the display body 11 changes to the display board 1.
This indicates that the vehicle rotates counterclockwise from the reference line 16 of No. 5 as shown by the arrow to display a left turning state.

Figure 8 shows that when the vehicle turns to the right, the display body 11 changes to the display board 15.
This indicates that the vehicle rotates clockwise from the reference line 16 as shown by the arrow to display a right-turning state.

Incidentally, the casing 10 is provided with a vehicle forward movement display section 26 and a vehicle body backward movement display section 27. These display sections are displayed by a lens 28 and a bulb 29 attached to the casing 10, as shown in FIG.

Further, as shown in FIG. 2, a plurality of valves 30 are arranged behind the display body 11, and these pulps 3O are fixed to the casing 10. These bulbs 30 are used to illuminate the display section 18 of the display body 11 at night.

In the above configuration, the display body 11 rotates in accordance with the rotation of the steering wheel 25, in other words, the turning of the vehicle body, and displays the display portion 18 on the display board 15, thereby providing convenience to the driver.

[Effects of the Invention] According to the present invention, the display body having the display portion as described above is rotated in accordance with the movement of the driving body, that is, the automobile, so that when displaying left or right turning of the automobile as in the conventional case, to LE
The structure is extremely simple compared to a structure in which the D chip is selectively turned on, and therefore has the advantage of being inexpensive and compact.

Further, according to the present invention, it is possible to display the turning direction according to the actual movement, and the movement of the driving body can be more accurately displayed than in the past, which is an intermittent approximation display of selective lighting of LED chips. can be recognized accurately.

In the above embodiment, the present invention has been described as displaying the position of the vehicle body, but the present invention is not limited thereto. For example, it can be applied to display the positions of airplanes and ships.
