Title: SHEET FOR PEN INPUT DEVICE AND METHOD FOR MANUFACTURING SHEET FOR PEN INPUT DEVICE
Abstract:
The objective of the present invention is to provide the same writing feel as when writing on paper with a writing instrument such as a ballpoint pen, when an instruction input is made by bringing an electronic pen into contact with a sheet. This sheet for a pen input device wherein a position indicated by an electronic pen is detected is contacted by the tip portion of the core body of the electronic pen, and is equipped with a resin film layer. When SR is the diameter of the tip portion of the core body of the electronic pen, δ is the amount by which the resin film sinks (which changes in response to the load when a load is applied to the tip portion of the core body of the electronic pen and contact is made), and μ is the dynamic friction coefficient between the tip portion of the core body and the resin film when a load is applied to the tip portion of the core body of the electronic pen and contact is made, an approximate straight line of data plotted by measuring with respect to the change in the load applied to the tip portion of the core body has a proportional relation μ∝δ/SR for the resin film layer.
