Abstract

PURPOSE:To reduce the space of a device and simplify connections and handle X-axis and Y-axis electrodes simultaneously by superimposing leading-out electrodes of X-axis and Y-axis conductive piece groups in two, namely, upper and lower stages to reduce the width of leading-out electrodes to half. CONSTITUTION:Leading-out electrodes 4 of X-axis conductive piece groups are constituted as the upper stage, and leading-out electrodes 5 of Y-axis conductive piece groups are constituted as the lower stage. An insulating sheet 6 or the like is arranged between both leading-out electrodes in the part, where one of them is put on the other, to prevent the short-circuit between them. Leading-out electrodes are superimposed in two, upper and lower stages in this manner to reduce the width of leading-out electrodes to half, and as the result, the width of connection cords is reduced to half to reduce the space of the device. Since a receptacle with two, upper and lower stages as a set can be used in case of cord connection, connection and disconnection of cords are simplified, and X-axis and Y-axis electrodes can be handled simultaneously.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a two-dimensional position coordinate detection device, and more specifically, it is composed of a plurality of divided conductive pieces separated by insulating parts extending in the same direction, and when pressed, X and Y axes with sufficient flexibility to make electrical contact
A two-dimensional position coordinate detection device in which groups of axial conductive pieces are arranged opposite to each other at regular intervals, characterized in that the lead-out electrodes of both of the conductive piece groups are stacked in two layers, upper and lower. Regarding.

A two-dimensional position coordinate detection device obtains an electrical signal by pressing a desired position on a flat or curved surface to bring the conductive pieces of the X-axis and Y-axis into contact at the desired position, and utilizes the obtained coordinate signal. It performs information processing, etc., and is often used as a CRT.
The device is installed on the display screen, and the operator presses a position corresponding to the desired information on the device with a finger or the like from above the device, and the operator interacts with the computer connected to the jLT to process information. It is something to do.

In a coordinate detection device in which an X-Y axis conductive piece group is made up of divided conductive pieces, the number of electrodes taken out from each conductive piece group is equal to the number of divided conductive pieces on both the X and Y axes, and the electrodes can be made compact and the electrode function Conventionally, when taking out the electrodes, the electrodes for the X and Y axes were placed side by side, which took up a large space, and the wires had the same width as the electrodes. The appearance was also unfavorable since it was connected to the device.

In particular, when trying to improve the resolution of position coordinates, the number of conductive pieces increases, and the lead-out electrodes also become wider, making it difficult to take out the conductive pieces.

The present invention solves the above-mentioned problems, and reduces the space and simplifies the connection by overlapping the lead-out electrodes of the X- and Y-axis conductive strip groups.

The present invention will be explained below based on the illustrated embodiments.

FIG. 1 is an explanatory diagram showing a conventional example, in which (a) is a plane, (
b) shows the end face of bb. Xlilli isoelectric group (
The extraction electrode (4) of 2) and the extraction electrode (5) of the Y-axis conductive piece group (3) are arranged horizontally in the same plane, and the extraction electrode (r) is
It occupied ll (L). When attempting to increase the resolution of two-dimensional position coordinates, the number of divided conductive pieces increases and the width (→) increases, causing the problem described above.

FIG. 2 is an explanatory end view showing one embodiment of the present invention, and
The lead electrode (4) of the axial conductive piece group (2) is on the upper stage, and the lead electrode (5) of the Y-axis conductive piece group (3) is on the lower stage.

Therefore, the lead-out electrode width is (c/2) from (2) in FIG.

Place an insulating sheet, etc. (6
) to prevent short circuit between both electrodes.

As described above, in the two-dimensional position coordinate detection device of the present invention, the extraction electrodes are stacked in two layers, upper and lower, so the width of the extraction electrodes can be halved, and as a result, the width of the connection cord is halved, and this device can also be used as a snowboard. In addition, when connecting the cord, it is possible to use a set of two upper and lower receptacles, making it easy to connect and disconnect the cord, and also having the advantage of being able to handle both the X- and Y-axis electrodes at the same time, making this an extremely effective invention. It is.
