Embodiment Construction

[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Throughout the drawings, the same reference numerals are assigned to corresponding constituent elements.

[0019] Referring to the accompanying drawings, FIG. 1 is a diagram showing main structural elements of a panel-type input device 10 according to a first embodiment of the present invention during non-input and input, and FIG. 2 is an exploded view showing the main structure of the panel-type input device 10. A rough perspective view of a feature.

[0020] The panel-type input device 10 has: a first electrode plate 16, an insulating first substrate 12, and a first conductive film 14 provided on one surface 12a of the first substrate 12; and a second electrode plate 22, which has an insulating property. The second substrate 18 and the second conductive film 20 provided on one surface 18 a of the second substrate 18 . The first substrate 12 and first conduct...

Abstract

The present invention provides a panel-type input device having a resistive-type configuration, having superior properties, such as impact resistance, writing durability, etc., and which is capable of preventing the conductive coats from sticking to each other due to a local pressing force applied by an input operation without degrading input operability. In the panel-type input device 10, at least one of a first conductive coat 14 of a first electrode plate 16 and a second conductive coat 20 of a second electrode plate 22 is formed by using a conducting polymer. The dot spacers 46 are formed in such a manner that a value A=H / D, representing a relationship between an overall height H[[mu]m] of each dot spacer measured from the surfaces 41a,20a of the first or second conductive coats 14,20, on which the dot spacers are formed, and a substantial disposition interval D[mm] of the dot spacers on the surface 14a,20a, is in a range of 1.5 < A < 6.0.

Description

technical field [0001] The present invention relates to a panel type input device. Background technique [0002] A panel-type input device is used as an electronic device equipped with a display device such as a personal computer, a portable information terminal (PDA), an automatic teller machine (ATM), etc., and the operator presses the desired position on the panel surface with a pen or finger to indicate the display device The input device of the two-dimensional coordinate data in is known. In particular, a panel-type input device having a transparent structure itself that can be superimposed on the screen of a display device such as an LCD (Liquid Crystal Display), PDP (Plasma Panel), or CRT (Braun Tube) is called a touch panel. It is widely used, and in recent years, it has also been installed in portable terminal devices having a mobile phone function. [0003] A resistive film type touch panel as one form of a panel-type input device has a structure in which a pair ...
