The control circuit 90 is housed in the instrument body D. The control circuit 90 includes a memory 91, and data (hereinafter referred to as chart data) as shown in the chart of FIG. 4 is stored in the memory 91 in advance. In this chart data, a plurality of setting specifications a to d
It is specified by the minimum graduation instructing position of the pointer 50, the rotation direction and the rotation angle width, and the minimum graduation instructing position, the rotation direction and the rotation angle width of the pointer 60. Here, the plurality of setting specifications a to d include data necessary for specifications of various measuring instruments.

Further, the control circuit 90 is provided with a memory 92, and in this memory 92, both hands 50 of the measuring instrument,
Each setting specification of 60 is stored. In this embodiment, the memory 91 is a ROM, and the memory 92
Consists of RAM.

Therefore, the control circuit 90 is configured to perform the following control. When the control circuit 90 is directly connected to the positive terminal of the battery B mounted on the passenger car when the instrument is mounted on the passenger car, the control circuit 90 causes the pointers 50 from the stored chart data in the memory 91. , 60 are read out and stored in the memory 92.

Here, the setting specifications of both hands 50 and 60 are as follows:
Regarding the pointer 50, the "minimum scale designation position" is "directly below" the setting specification a, the "rotation direction" is "clockwise" of the setting specification a, and the "rotation angle width" is "200" of the setting specification a.
For the pointer 60, the "minimum scale indication position" is "directly below" the setting specification a, the "rotation direction" is the "counterclockwise direction" in the setting specification b, and the "rotation angle width" is set. It is selected from the stored chart data of the scale 91 so as to be “150 °” of the specification a.

The control circuit 90 has a memory 92.
Guideline 5 based on the stored data
The rotary inner units 20, 30 are drive-controlled so that 0, 60 are maintained on the surface of the scale 40 as shown in FIG.
In this drive control, the pointer 50 indicates "0 km / h" corresponding to the minimum scale of the scale 40a at the pointer 52, and the pointer 60 corresponds to the minimum scale of the scale 40b at the pointer 62. "0r.pm" is designated.

Further, the control circuit 90 moves the pointer 50 to the scale plate 40 when the ignition switch IG is turned on.
The rotary inner unit 30 is drive-controlled based on the detection output of the vehicle speed sensor 70 so as to rotate between the minimum scale and the maximum scale of the scale portion 40a, and the pointer 60 is also used for the scale 60.
The rotating internal unit 20 is drive-controlled based on the detection output of the rotation sensor 80 so as to rotate between the minimum scale and the maximum scale of the scale unit 40b.

In the first embodiment constructed as described above, the control circuit 90 is directly connected to the positive terminal of the battery B when the instrument is assembled to the passenger car. Then, the control circuit 90 operates by being supplied with power from the battery B, reads out the setting specifications of both hands 50 and 60 from the stored chart data of the memory 91 as described above, and stores them in the memory 92.

With such storage, the control circuit 90 concerned
Is based on the data stored in the memory 92,
30 is driven and controlled. As a result, the pointer 50 is "0" corresponding to the minimum scale of the scale portion 40a in the pointer portion 52.
The pointer 60 is rotated by the rotary inner unit 30 to indicate "km / h", and the pointer 60 indicates "0 r.p.m." corresponding to the minimum scale of the scale portion 40b by the pointer portion 62 thereof. It is rotated by the rotating internal unit 20. Therefore, the pointer 50
Indicates the minimum scale of the scale 40a on the surface of the scale 40, and the pointer 60 indicates the minimum scale of the scale 40b on the surface of the scale 40.

In such a state, when the ignition switch IG is turned on and the passenger car is in a traveling state, the vehicle speed sensor 70 detects the vehicle speed of the passenger car,
The rotation sensor 80 detects the rotation speed of the engine of the passenger car. Then, the detected vehicle speed and the detected rotation speed are input as data to the control circuit 90.

Then, the control circuit 90 drives and controls the rotary inner unit 30 based on the detection output of the vehicle speed sensor 70, so that the pointer 50 is calibrated on the surface of the graduation plate 40 at the left side in FIG. By rotating along the portion 40a to instruct the vehicle speed and drive-controlling the rotating internal unit 20 based on the detection output of the rotation sensor 80, the pointer 60 is placed on the surface of the scale plate 40 on the right side in FIG. It rotates along the scale 40b to indicate the rotation speed of the engine. Where, for example,
When the vehicle speed increases, the pointer 50 rotates along the scale 40a in the clockwise direction shown in FIG. 1, and the pointer 60 rotates along the scale 40b in the counterclockwise direction shown in FIG.

As described above, in the first embodiment, the instrument main body D and the graduation plate 40 configured as described above.
Then, both of the pointers 50 and 60 are used to give both the vehicle speed instruction and the rotation speed instruction. Therefore, in the instrument, both the vehicle speed instruction and the rotation speed instruction are given by the single scale 40.
As a result, it is possible to reduce one of the graduation boards which are separately required for the speedometer and the tachometer.

The specifications for setting the initial rotation positions of the hands 50 and 60 (positions indicating the minimum scales of the scales 40a and 40b), the rotation direction and the rotation angle width are stored in the memory 91. It suffices to specify using the chart data stored in advance, and even if the setting specifications of the pointers 50 and 60 are not separately prepared for each of the vehicle speed instruction and the rotation speed instruction, the setting will impose a new development and design burden. It can be easily done without it. Here, since the rotation angle width of each of the hands 50 and 60 is set by using the chart data described above, if the rotation angle width of the chart data is widened, each of the hands 5 according to the user's preference will be set.
A wide angle setting of the rotation angle width of 0 and 60 can be easily performed.

Then, the control circuit 90 is operated by being supplied with power from the battery B, and the pointers 5 are selected from the stored chart data in the memory 91.
The setting specifications 0 and 60 (the setting specifications in the second embodiment) are read out and stored in the memory 92 in substantially the same manner as in the first embodiment.

With such a storage, the control circuit 90 concerned
Drives and controls the rotating internal units 20, 30 based on the data stored in the memory 92 (data stored in the second embodiment). As a result, the pointer 50 is rotated by the rotating internal unit 30 so that the pointer portion 52 indicates "0 km / h" corresponding to the minimum scale of the scale portion 40a, and the pointer 60 is rotated by the pointer portion 62. It is rotated by the rotating internal unit 20 so as to indicate "0 rpm" corresponding to the minimum scale of the scale portion 40b.

As a result, the pointer 50 is rotated by the rotating internal unit 30 so that the pointer 52 indicates "0 km / h" corresponding to the minimum scale of the scale 40a. Therefore, the pointer 50
Indicates the minimum scale of the scale portion 40a on the surface of the scale 40 (at a position of 20 ° counterclockwise from directly below).

In such a state, when the passenger vehicle is placed in a traveling state as the ignition switch IG is turned on, as in the second embodiment, the control circuit 90 moves within the rotation based on the detection output of the vehicle speed sensor 70. By controlling the driving of the machine 30, the pointer 50 is rotated along the scale 40a on the surface of the scale 40 at the upper side in FIG. 6 to indicate the vehicle speed.

It is similar to the embodiment.

In the fifth embodiment configured as described above, when the control circuit 90 is directly connected to the positive terminal of the battery B as in the second embodiment, this control circuit 9
0 operates by being supplied with power from the battery B, and reads the setting specifications of both hands 100 and 110 from the stored chart data in the memory 91 and stores them in the memory 92 substantially in the same manner as in the second embodiment.

With such storage, the control circuit 90 concerned
Drives and controls the rotating inner units 20, 30 based on the stored data in the memory 92 (stored data in the fifth embodiment). As a result, the pointer 100 is rotated by the rotary inner unit 30 so that the pointer portion 102 indicates "0 km / h" corresponding to the minimum scale of the scale portion 40c.
The 0 is rotated by the rotating internal unit 20 so that the pointer 112 indicates "0 rpm" corresponding to the minimum scale of the scale 40d. Therefore, the pointer 100 indicates the minimum scale of the scale portion 40c (at a position of 45 ° in the clockwise direction from directly below) on the surface of the scale plate 40A,
The pointer 60 is the minimum scale of the scale portion 40b on the surface of the scale plate 40 (at a position of 45 ° clockwise from directly below).

00 and 110 are used to give both a vehicle speed instruction and a rotation speed instruction. Therefore, in the fifth embodiment, the graduation plate 40A and the pointers 100 and 110 are the same as the second dial.
Although it is different from that described in the embodiment, by using the stored chart data of the instrument main body D and the memory 91 described in the second embodiment, substantially the same operational effect as the second embodiment is achieved. it can.

The specifications for setting the initial rotational positions, rotational directions and rotational angular widths of the hands 100 and 110 are based on the chart data stored in the memory 91 described in the second embodiment. It may be specified by utilizing the setting, and the setting can be easily performed for each vehicle speed instruction and rotation speed instruction or without preparing the setting specifications of the hands 100 and 110 separately from the instrument of the second embodiment.

Further, in the fifth embodiment, both hands 10
0, 110 were constructed as described above. Therefore, guideline 1
00 is at the position indicating the minimum scale of the scale portion 40c, and the pointer 110 is at the position indicating the minimum scale of the scale portion 40d, these pointers 100, 110
The pointer portions 102 and 112 of the
Compared with the case where the base ends of the above are supported at the centers of the respective surfaces of the rotary bases 101 and 111, they are arranged in parallel at a narrower interval.

Therefore, the pointer 100 has the scale portion 40c.
When the pointer 110 is in the position for instructing the minimum scale of the scale section 40d and the pointer 110 is in the position for instructing the minimum scale of the scale portion 40d. You can secure a sense of unity and look good.

Although the first to fifth embodiments have been described above, in each of these embodiments, the chart data stored in the instrument main body D and the memory 91 are shared. Therefore, when configuring the instrument for indicating both the vehicle speed and the engine speed, it is only necessary to separately prepare, for example, a graduation board having a configuration that suits the user's taste. It is not necessary to adopt various parts.

Further, since the instrument main body D and the chart data are shared as described above, it is not necessary to separately prepare the specification data of the instrument main body D and the pointer for the vehicle speed instruction and the engine speed instruction. .
