Abstract
A pressure sensitive touch panel in which the position of an inner periphery of a window frame is disposed opposite to spacers, whereby a conductive film, which bends together with a flexible insulating plate when an operator presses the window frame, is caught by the spacers. In addition, protrusions are provided above the surface of an insulating layer, and inserted between the window frame and the flexible insulating plate or between the insulating layer and the conductive film, whereby the conductive film does not contact the upper edge of the end portion of the insulating layer. Thus, it is possible to avoid the damage to the conductive film due to the bending of the window frame and to avoid input of unintended and erroneous position data of input coordinates.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
