【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic view showing a configuration of a display device according to the present invention provided in a heater controller of an automobile, (A) is a side sectional view and (B) is a front view. The same components in FIG. 1 as those in the conventional example shown in FIG. 2 are designated by the same reference numerals.

As shown in the drawing, the display panel 1 is provided with five indicators 2 which are graphically showing the control state of the controller, in this example, the blowing position of the hot air, and are arranged in a row on the left and right. A lever slit 3 is formed along these indexes 2. The display panel 1 is configured such that the light from the rear transmits only the portion of the index 2, and the light transmitted through the index 2 is diffused. A control lever 4 for selecting the hot air blowing position is provided while penetrating the lever slit 3 of the display panel 1.

The control lever 4 is supported by a support member 11 behind the display panel 1 so as to be slidable along the lever slit 3, and an operation knob 5 is attached to the tip thereof. There is. The support member 11 is fixed to the housing member 16. The rear end of the control lever 4 is rotatably connected to a drive lever 13 pivotally supported by the base body 12, and the drive lever 13 is further connected to a control mechanism (not shown). Therefore, when the control lever 4 is slid by operating the operation knob 5, the drive lever 13 is rotated and the blowing position of the warm air is controlled.

A knob lens 6 is embedded in the control lever 4 along the axis thereof from near the center to the tip of the operation knob 5. The rear end surface of the knob lens 6 is formed obliquely to form a light receiving portion 6a for taking in light, and the front end surface is a diffusion surface for diffusing emitted light.

On the other hand, behind the display panel 1, a thick plate-shaped light guide 7 corresponds to the index 2 and other indexes (not shown) below the index 2, and a gap 14 is provided between the index panel 2 and the display panel 1. It is arranged with the. A recess 7a is formed in the center of the rear part of the light guide 7, and a light source 8 using a small incandescent lamp is arranged in the recess 7a. Further, on the upper end of the light guide 7, there is formed a ridge 7b for guiding light toward the light receiving portion 6a of the knob lens 6. The light guide 7 and the light source 8 are supported by the support member 11 together with the control lever 4.

Further, as a feature of the display device of the present invention, a plate-shaped lever position display member 15 made of a light-transmitting coloring material is loosely inserted in the gap 14 between the display panel 1 and the light guide 7. It is attached under the control lever 4 in the closed state. Therefore, when the operation knob 5 is operated and the control lever 4 is slid, the lever position display member 15 also moves along with the control lever 4 along the index 2. The lever position display member 15 is formed to have a size corresponding to one of the indexes 2 described above, and its color is the color of the light of the light source 8 so that the emission color of the index 2 changes as described later. Also, it is appropriately set according to the colors of the light guide 7 and the index 2.

In the above structure, when the light source 8 is turned on, the light emitted from the light source 8 is guided to the light guide 7 and sent to each index 2. At that time, a part of the light passes through the lever position indicating member 15. The light sent to each index 2 passes through each index 2 and diffuses in front of the display panel 1. In this way, each index 2 emits light. Further, the light from the light source 8 guided to the ridge portion 7b of the light guide 7 enters the lens lens 6 from the light receiving portion 6a of the knob lens 6, and diffuses from the tip of the operation knob 5 to the front of the display panel 1. .

As for the emission color of each of the indicators 2, assuming that the light guide 7 is colorless and transparent, the indicator 2 is white, and the lever position display member 15 is blue, the light color of the light source 8 using an incandescent light bulb is amber. Therefore, as shown in FIG. 1B, only the light emission color of one index 2a overlapping the lever position display member 15 becomes white due to the combination of blue and amber, and the other four index 2 colors. The emission color is the same amber as the light color of the light source 8. That is, among the plurality of indicators 2 on the display panel 1, only the emission color of the indicator 2a corresponding to the position of the control lever 4 is changed by the lever position display member 15.

As described above, in the display device having the above-described configuration, the index 2 itself displays the position of the control lever 4 operated and slid by the operation knob 5, and therefore the indicator 2 itself displays the position of the light emission color. Even if the line of sight is oblique to the display panel 1, unlike the case of judging from the tip position of the operation knob 5 protruding above the display panel 1 as in the conventional example, the position of the control lever 4, that is, the selected position. The hot air blowing position can be seen accurately and quickly.

In the above embodiment, the case where the display device according to the present invention is applied to the display device of the heater controller of the automobile has been described, but it can be applied to the display devices of various other control devices. Needless to say.
