2. Description of the Related Art Generally, wiring and a circuit board for driving a meter are provided on the back surface of a case (meter case) of an instrument panel to which various meters are attached. This circuit board has conventionally been a strong plate made of a phenol resin or the like, but in recent years, a flexible board has often been used.

FIG. 6 is a front view of a conventional vehicle combination meter 50 equipped with a speedometer 51, a tachometer 52, a fuel gauge 53, a water temperature gauge 54 and the like. On the back surface of such a combination meter 50, for example, a flexible substrate 60 as shown in FIG. 7 provided with a circuit for driving these meters is attached.

In the case of the combination meter 50 for an automobile, the types of meters mounted on the combination meter 50 generally differ depending on the grade of the automobile, and the combination meter 50 has a plurality of types of instrument variations. Will do.
For example, the tachometer 52, which is almost always attached to the combination meter 50 of a sporty type automobile, cannot be attached to the combination meter 50 of a family type or a business type automobile even if the same type of automobile is used. There is. In another example, a tachograph capable of recording the operation of a vehicle may be provided in a speedometer of a business vehicle.

In such a case, the flexible substrate 60 attached to the back of the combination meter 50 also has
A variation corresponding to the instrument variation is required. However, if a plurality of types of flexible substrates 60 are manufactured in accordance with such instrument variations, the cost of the combination meter 50 will increase. Therefore, conventionally, a flexible substrate 60 that can be adapted to any instrument variation is provided with one flexible substrate.
Unnecessary parts are removed depending on the type and instrument variation.

For example, a case will be described in which the flexible substrate 60 shown in FIG. 7 is made for the ordinary combination meter 50 shown in FIG. 6 and can be applied to a combination meter with a tachograph. In such a case, a main board 61 for an instrument other than the speedometer and a sub-board 62 for the speedometer are provided on the flexible board 60, and when the flexible board 60 is attached to the combination meter 50 without a tachograph. When the flexible board 60 is used for a combination meter in which a tachograph is replaced by a tachograph, the sub-board 62 is cut off along the separation line 63 and only the main board 61 as shown in FIG. Mounting was done.

[0007]

However, there is a case where an automobile that has been mounted and shipped with a combination meter 50 without a tachograph is changed to a tachograph at a later time according to a user's request. In such a case, as shown in FIG. 9 (the flexible substrate is simplified for the sake of description), the sub-substrate 62 which is not required when the tachograph is mounted is separated from the main substrate 61 along the separation line 63 by scissors or the like. However, when the separation line 63 has a complicated shape that bends in the middle, there is a problem that the cutting workability is poor and the work takes time. In addition, the separation line 63 at the time of cutting
In some cases, it is not possible to cut the wiring along the line, and if the wiring on the main board 61 is cut by mistake, the entire flexible board 60 must be replaced.

In view of the above, according to the present invention, when a part of the flexible substrate mounted on the back surface of the meter case is cut and removed later, the part to be removed is easily separated from the main substrate with good workability, and furthermore, there is a cutting error. It is an object of the present invention to provide a flexible mounting structure of a meter case which can be performed without any problem.
