Problems solved by technology

In such a case, since the frame area of ​​the touch panel is completely exposed, this problem cannot be solved with the conventional resistive touch panel having an ITO coating, and a more expensive capacitive touch panel tends to be used.

Embodiment Construction

[0049] 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.

[0050] 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 the feature, image 3 It is a partially enlarged cross-sectional view of the panel-type input device 10 .

[0051] 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 prov...

Abstract

The present invention provides a panel-type input device having a resistive-type configuration, which can reduce an operation-impermissible area including a frame area and also can prevent a coordinate input precision from being degraded due to damage of a conductive coat. When a first electrode plate 16 is laid or superposed on a display device 52 and the panel-type input device is mounted on the display device 52, a second electrode plate 22 is exposed to perform an input operation by pressing the second electrode plate 22 with a pen or a finger, etc., in the outer peripheral portion of the input-permissible area 44 adjacent to a frame area 42. A second conductive coat 20 of the second electrode plate 22 is formed by using the conducting polymer. An electronic apparatus 50 and a casing 54 integrately comprise a frame attaching member 56 for attaching the panel-type input device 10 on the display device 52. The attaching member 56 is disposed on the outer surface 18b of the second substrate 18 of the second electrode plate 22 of the panel-type input device 10 at a location where the attaching member 56 does not overlap the input-permissible area 44.

Description

technical field [0001] The present invention relates to a panel type input device. The present invention also relates to electronic equipment provided with 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 resi...
