Problems solved by technology

However, when the lower surface of the base and the upper surface of the flexible substrate are bonded, excess adhesive may be squeezed out, or the adhesive layer may be unevenly formed containing air bubbles, which may cause a decrease in detection sensitivity. reduction, false detection

Abstract

The invention provides a coordinate input device for avoiding the reduction of detection sensivity and detection errors because of bubbles mixing in a joint part, uneven thickness and exposing of adhesives from the joint part. The coordinate input device (1) comprises: a substrate (20) which comprises more than one detecting elements (20a) of deformation detection elements (21) and wiring part (20b) extended from the detecting elements (20a); and an operation body (10) which comprises a base (11) and an operation part (18) protruding from the upper surface of the base, wherein the substrate (20) is fixedly connected with the lower surface of the base (11), and on the lower surface of the base (11), more than one grooves (33d) is generated on outside of the corresponding area of the deformation detection elements (20).

Description

technical field [0001] The present invention relates to a coordinate input device, and more particularly, to a coordinate input device with improved operability by having a structure that can be properly assembled. Background technique [0002] In recent years, notebook computers or game machines are sometimes equipped with a coordinate input device, which reads an input operation in which an operator tilts a rod-shaped operation part such as a stick with a finger as an electrical signal, and reflects it on the screen, for example, selection of an editing position, positioning of a cursor, etc. Action waiting. [0003] In addition, the above-mentioned coordinate input device becomes a defective product when the detection sensitivity of the input operation deteriorates due to a mistake in the assembly process, and the manufacturing cost increases due to the expense of inspection and maintenance. Therefore, the structure of the detection sensitivity of the coordinate input de...
