BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic induction type digitizer sensor plate used for a figure input device for CAD.

[0002]

2. Description of the Related Art Conventionally, an electromagnetic induction type digitizer sensor plate configured as shown in FIG. 4 has been used for an information input device such as CAD. The sensor wire 2 is wired as shown in FIG. First, a plurality of sensor wire arranging pins 4 are arranged around the outer side of the insulating flat plate 3 at a predetermined interval, and the sensor wire 2 having an insulating coating on the wire arranging pins 4 is used for the X-axis direction and the Y-axis. Wiring is performed in a predetermined pattern while being hooked and folded back in each direction, and the sensor line terminals 8, 8 in the X-axis direction and the Y-axis direction are led out from the insulating flat plate 3. Next, the adhesive 5 is applied to the sensor wire 2 excluding the peripheral portion on the insulating flat plate 3, and the sensor wire 2 is embedded and fixed on the flat plate 3. afterwards,
The sensor wire folded-back portion 7 is removed from the wiring pin 4 and is bent and arranged on the plate peripheral portion 11 on the flat plate 3 not filled with the adhesive, and the sensor wire folded-back portion 7 is further coated with the adhesive 5A for insulation. The sensor wire folded portion 7 was fixed to the peripheral portion 11 on the flat plate 3.

[0003]

In the conventional digitizer sensor plate, the processing of the folded portion of the sensor line on the outer side of the insulating flat plate is performed by filling and fixing with an adhesive. For this reason,
In the work of applying fixing glue to the sensor line folded portion, the sensor wire folded portion is fixed to the left insulating flat plate protruding from the adhesive layer, the risk of causing disconnection in the protruding sensor wire folded portions during the production process there were. Also,
Work to adhere the sensor line folded portion with an adhesive insulating flat plate takes time to solidification of the adhesive, on inferior in workability, there is a drawback that the weight amount corresponding sensor plate of the adhesive becomes heavy.

The present invention solves the above-mentioned drawbacks, and provides a digitizer sensor plate that protects the folded portion of the sensor wire from the risk of disconnection by a simple means and is easy to handle during the manufacturing process.

[0005]

At predetermined intervals, each X-axis and Y-axis directions on the sensor line 2 an insulating flat plate 3 which has been subjected to insulating coating SUMMARY OF THE INVENTION, by providing a sensor line folded portion 7 on the outer side of the insulating flat plate 3 It was laid in a meandering shape, X-axis direction and the Y-axis direction in the sensor lines 2 laid lead wire end portion 8 derived from insulating flat plate 3, the insulating flat peripheral portion 11 sensor line 2 adhesive was divided 5
More in digitizer sensor plate to be filled fixed, bent on the insulating flat outer sensor lines folded portion 7 is not filled with the adhesive 5 in the insulating flat peripheral portion 11
Together they are arranged Te, to the sensor line folded portion 7
Is a terminal lead wire outlet for covering the sensor wire return part 7.
In which the protective cover 6 for Bei is disposed.

[0006]

[Action] After the sensor wire folded portion is arranged bent in the insulating flat plate periphery, by the sensor line folded portion is broken covered with a protective cover, which prevents accidental disconnection of the sensor line folded portion in a working process . In addition, using the protective cover in place of a conventional adhesive, weight of the sensor plate is achieved, the easy handling during the manufacturing process. It should be noted that if the protective cover is detachably fixed to the insulating flat plate by screwing or the like, it is convenient for work such as repair of the sensor plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. FIG. 1 is a sectional view of a sensor plate showing an embodiment of the present invention, and FIG. 2 is a partial perspective view showing an embodiment of a protective cover.
FIG. 3 is a diagram for explaining wiring of sensor lines. Figure 1
In the figure, 2 is a sensor wire having an insulating coating such as an ultra-fine magnet wire, 3 is an insulating flat plate made of transparent glass or epoxy glass plate, 5 is an adhesive to be a filling layer
6 is a protective cover made of a plastic material.

[0008] The present invention of a digitizer sensor board similar to the described in the column of the prior art is manufactured as follows. Well
Instead, as shown in FIG. 3, the sensor wires 2 are sequentially hooked and folded back on a plurality of sensor wire arranging pins 4 arranged at a predetermined interval on the outer peripheral edge of the insulating flat plate 3 in the X-axis direction and the Y-axis direction, respectively. Arrange in a prescribed pattern . Then , the terminal leads 8, 8 of the sensor lines 2, 2 in the X-axis direction and the Y-axis direction are led out from the insulating flat plate 3. Then, the peripheral portion 11 on the insulating flat plate 3 in which the sensor wire 2 is wired in a predetermined pattern
The adhesive 5 is applied from above the sensor wire 2 excluding the above to fix the sensor wire 2 on the insulating flat plate 3. Next, the folded-back portion 7 of the sensor wire 2 is removed from the sensor-wiring pin 4 and is bent and arranged on the peripheral portion 11 on the insulating flat plate 3 to which the adhesive 5 is not applied.

[0009] Next, disposed on the insulating flat plate 3 the folded portion 7 cover 6 so as to cover the sensor lines 2 which is folded over the insulating flat plate 3 (that shown in FIG. 2 FIG.) As shown in FIG. 1,
The protective cover 6 is fixed to the insulating flat plate 3 with screws 10 or the like. At this time, the terminal lead portions 8, 8 of the sensor wires 2, 2 are led out from the sensor wire lead-out port 9 provided in the protective cover 6, and the sensor plate 1
Is configured. Needless to say, the shape of the protective cover 6 is not limited to that of the embodiment and can be variously changed. Further, when the protective cover 6 is attached and fixed to the insulating flat plate 3, the protective cover 6 may be fixed by using an adhesive, or a groove may be provided in the protective cover 6 and the protective cover 6 may be fitted to the insulating flat plate 3.

[0010]

[Effect of devised the present invention of the digitizer sensor plate, sensor
In the sensor board sensor line folded portion is outside the insulating flat plate at line wiring, with the sensor line folded portion is arranged folded in an insulating flat plate periphery, the protective cover insulating flat plate disposed to cover the sensor line folded portion since those fixed, preventing accidental disconnection due to external force or the like during the production process is achieved, a high sensor plate reliability. Further, by using a protective cover instead of the conventional adhesive, the weight of the sensor plate can be reduced and the handleability during the manufacturing process can be improved.
