Description

[Detailed description of the invention] Industrial field of application This invention relates to a pointer-type display device installed in automobiles.

Prior Art As disclosed in Japanese Utility Model Application No. 51-1987 and Japanese Utility Model Application No. 54-13365, there is a
It is equipped with a speedometer and tachometer that display speed and engine revolutions.

For example, as shown in FIG. 4, the speedometer is constructed so that a linear pointer 3 rotates on the front of a display panel 1 on which a scale 2 corresponding to the speed is arranged in an arc shape.
The pointer 3 is rotated by a mechanical drive mechanism or an electromagnetic drive mechanism according to the rotational speed of the transmission, so that the pointer 3 points to a scale 2 that corresponds to the speed.

The tachometer is similar, for example, as shown in FIG. The rotation of the needle is transmitted to and rotated by an appropriate driving means to a pointer 6, so that the pointer 6 indicates a scale 5 that corresponds to the engine speed.

Problems that the invention attempts to solve Conventional speedometers have a pointer 3 on the front of the display panel 1.
rotates, the pointer 3 is always visible, and the relationship between the display panel 1 and the pointer 3 is always constant, so when judging the speed, read the scale 2 on the display panel 1 where the pointer 3 is pointing. Judgment had to be made, and judgment required skill. It was also difficult to immediately judge the degree of acceleration from the movement of the pointer 3.

A similar problem occurred with the tachometer.

Means for Solving Problems This invention consists of a display panel with a display window of a predetermined shape opened, a short hand portion and a long hand portion formed by bending at an acute angle of 90° or less, and the short hand portion is inside the display panel. This is a pointer-type display device that is hidden in the display panel and has a pointer that is rotatably provided at the back of the display panel so that the long hand is exposed through the display window of the display panel.

Function In this device, the length of the pointer visible through the display window of the display panel changes as the pointer rotates.

Embodiments Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the case where the device is used in a speedometer. In the figure, numeral 10 is a display panel of a pointer-type display device, and a semicircular display window 11 is opened therein. The arcuate peripheral edge 11a of the display window 11 is provided with a scale 12 corresponding to the display of speed. 13 is a guideline,
As shown in FIG. 2, the short hand part 13a and the long hand part 13b are formed by bending the short hand part 13a at an acute angle of 90° or less.
A centerpiece 14 is formed at the end of 3a to serve as the center of rotation. This pointer 13 is arranged so that the short hand part 13a is hidden within the display panel 10 and the long hand part 13b is exposed from the display window 11, and the eyeball 14 is arranged below the center of the linear peripheral edge 11b of the display window 11. The eye 14 of the pointer 13 is connected to a drive mechanism (not shown) that rotates the pointer 13 in accordance with the rotational speed of the transmission.

In addition, in the above-mentioned speedometer, the long hand portion 13b of the pointer 13
The scale 12 is set so that 0 is indicated with the tip slightly exposed from the display window 11.

In the above-mentioned speedometer, the pointer 13 rotates around the eyeball 14 in response to changes in speed, and as the speed increases, it rotates to the right, and the long hand 13b indicates a value according to the speed, and its exposed length becomes longer. Become.

Figure 3 is a drawing showing the case where it is applied to a tachometer.
In the case of a tachometer, the scale 15 on the display panel 10 is set to a value that matches the engine speed.

In each of the above embodiments, the display window 11 formed in the display panel 10 may have a rectangular shape other than a semicircle.

Effects of the invention According to this invention, the length of the long hand of the pointer exposed from the display window of the display panel changes as the pointer rotates, so it is easy to see the length of the long hand exposed from the display window. This allows you to easily recognize speed and engine speed, improving visibility. Also, by looking at the change in the length of the long hand, you can instantly know the degree of change in speed and engine speed.
