SOLUTION: In front of a dial plate 3 provided with designs of dial and letters, a pointer 4 rotating for a specific angle is provided and a pointer stopper 5 regulating the rotation angle of the pointer 4 is provided on the dial plate 3. The pointer stopper 5 is made of colorless synthetic resin having transparency. At the back of the pointer stopper 5, a light source 8 such as an incandescent lamp is provided and a light case 10 for guiding the light from the light source 8 is provided in between the dial plate 3 and a circuit board 9 so as not to diffuse the light to the pointer stopper 5. The movement 11 of such as a cross coil type meter body is put on the circuit board 9 and rotates the pointer 4 via a pointer axis 12. By making the pointer stopper 5 serve as an alarm indicator, the design on the dial plate 3 and the arrangement of the pointer stopper 5 and alarm indicator are facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indicating instrument provided with an alarm display unit such as a fuel gauge having a remaining amount alarm display unit mounted on a vehicle and an information display unit for notifying an enlarged display of a low remaining amount. It is about.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional indicator having a warning display section and a notification display section, for example, an indicator 1 having a fuel level indicator such as a fuel gauge, has a design 2 such as scales and characters.
Is provided on the front surface of the dial 3 provided with a pointer 4 which rotates by a predetermined angle. The dial 3 is provided with a pointer stopper 5 for regulating the rotation angle of the pointer 4. An arbitrary position on the dial 3 is provided with a remaining amount warning display section 6 which lights up when the remaining fuel amount of the vehicle falls below a predetermined amount and displays an alarm. Reference numeral 7 denotes a dial plate provided around the dial.

[0003]

The indicating instrument 1 such as a fuel gauge has a small display area of the dial 3 as compared with a speedometer or an engine tachometer (not shown). It was difficult to arrange the display unit 6.
Therefore, the present invention provides an indicating instrument that can easily arrange a design on a dial, a pointer stopper, and an alarm display section.

[0004]

In order to achieve the above object, the present invention provides a pointer which is located at the front of the dial and rotates by a predetermined angle, a pointer stopper which regulates the rotation angle of the pointer and can emit light. It is provided with.

A pointer positioned at the front face of the dial and rotating by a predetermined angle, a pointer stopper for regulating the rotation angle of the pointer and formed of a translucent member, and a pointer provided behind the pointer stopper are provided. A light source for illuminating the pointer stopper with the light source.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An indicating instrument according to the present invention comprises a pointer 4 which is located on the front of a dial 3 and rotates by a predetermined angle, and a pointer stopper 5 which regulates the rotation angle of the pointer 4 and can display light. It is provided.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a front view of one embodiment of the present invention, and FIG. 2 is a sectional view taken along line AA in FIG. The same and corresponding parts as those in the conventional example are denoted by the same reference numerals, and detailed description thereof will be omitted.

The indicating instrument of the present invention includes a dial 3 provided with a design 2 such as a scale or a character. On the front surface of the dial 3, there is provided a pointer 4 which rotates by a predetermined angle. The dial 3 is provided with a pointer stopper 5 for regulating the rotation angle of the pointer 4. The pointer stopper 5 is made of a transparent and colorless synthetic resin. Reference numeral 8 denotes a light source such as an incandescent lamp provided behind the pointer stopper 5. Reference numeral 9 denotes a circuit board. A light case 10 is provided between the dial 3 and the circuit board 9 for guiding light from the light source 8 to the pointer stopper 5 so as not to diffuse. Reference numeral 11 denotes a movement such as a cross-coil instrument main body which is mounted on the circuit board 9 and rotationally drives the hands 4 via the hands 12.

In this embodiment, the light source 8 is turned on when the fuel remaining amount of the vehicle is reduced to a predetermined amount or less, and the light of the light source 8 illuminates the light-transmitting pointer stopper 5 to emit an alarm. .

The distal end of the pointer stopper 5 of this embodiment is formed in a hemispherical shape and functions as a lens, and collects light from the light source 8 to make it easy to recognize the lighting state. .

As described above, since the pointer stopper 5 also functions as the alarm display section, the design 2, the pointer stopper 5 and the alarm display section on the dial 3 can be easily arranged. Further, since the conventional alarm display unit also serves as the pointer stopper 5, the number of parts can be reduced as compared with the conventional case.

Further, since the pointer stopper 5 performs light emission display as an alarm display section, a novel display form which has not existed conventionally can be obtained.

In this embodiment, the pointer stopper 5 is formed of a light-transmitting colorless synthetic resin. However, the present invention is not limited to this embodiment. It may be formed of a synthetic resin. In this case, the pointer stopper 5
Can be noticeable when an alarm is displayed, but less noticeable when not lit.

When the diameter of the pointer stopper 5 is designed to be small, an alarm display is arranged adjacent to the standing position of the pointer stopper 5, and the pointer stopper 5 is integrated with the display lens provided on the display. By forming, the number of components can be reduced without separately forming the display lens and the pointer stopper 5, and moreover, the high-intensity light emission of the pointer stopper 5 and the reliable transmission of the display lens by the light emission are possible.

As a second embodiment, as shown in FIG. 3, a light emitting diode formed in a lens shape with a resin as a light source is used.
The leading end may be formed as an extension to serve as the pointer stopper 5.
In the case of the present embodiment, it is possible to further reduce the number of parts as compared with the above embodiment.

Although each of the above embodiments is applied to a fuel gauge, it is not limited to the above embodiments.
For example, it may be used for a speed warning of a speedometer. Further, it may be used not only as an alarm display but also as a notification display unit for notifying, for example, an enlarged display of a low remaining amount.

[0017]

As described above in detail, the present invention includes a pointer located at the front of the dial and rotating by a predetermined angle, and a pointer stopper which regulates the rotation angle of the pointer and can display light. Thus, the design on the dial, the pointer stopper, and the light emitting display unit can be easily arranged. Further, since the conventional alarm display unit also serves as the pointer stopper, the number of parts can be reduced as compared with the conventional case.

Further, since the pointer stopper performs light emission display as an alarm display section, a novel display form which has not existed conventionally can be obtained.
