Title:
PRESSURE SENSITIVE TOUCH PANEL AND INFORMATION EQUIPMENT HAVING THE SAME
Document Type and Number:
Japanese Patent JP3781722
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent possibility of false input of a signal by pressing to a window frame and breaking a conductive film by pressure to the film.
SOLUTION: By making an inner circumference end surface 11a of a window frame 11 of a case 10 face a spacer 19 adjacent to an insulation layer 21, when an operator or a dedicated pen presses the window frame 11, a conductive film 22 deformed in conjunction with a film 13 is accepted by the spacer 19. A projection 16 is formed on a surface (the side of the window frame 11) of the film 13 or on the insulation layer 21, so that the conductive film 22 on the film 13 deformed in conjunction with the window frame 11 is accepted by the opposite surface (the upper surface of the insulation layer 21) facing the projection 16 formed on the insulation layer 21 or the projection on the insulation layer 21.
