Abstract

The invention relates to a capacitance type touch control panel input device for user holding to produce capacitance inductor of capacitance type touch control panel. The capacitance type touch control panel comprises: a conductive pen head, made of conductive material for contacting capacitance type touch control panel; a pen body, one end of which connects or deploys conductive pen head; and a connection part, between pen head and pen body, for user holding capacitance inductor producing a capacitance type touch control panel with conductive pen head. The invention comprises conductive pen head, pen body of relative big area for contacting user palm and for user holding, and finger touchable pen body; conductive pen head and connection part can be scarf joint in pairs. The conductive pen head can uses polyester as inside filler of pen head, uses metal material as clad, or uses mixed polyester and metal material as pen head conductive material to increase contact surface with capacitance type touch control panel, thereby resolving problem of relative short moving distance resulting from relative large area of finger for contacting capacitance type touch control panel, and capacitance inducted variation resulting from sweating of hand.

Description

technical field [0001] The present invention relates to an input device, in particular to an input device for a touch panel and an input device for a capacitive touch panel that is held by a user to generate capacitive sensing of the capacitive touch panel. Background technique [0002] Existing touch panel products are classified into capacitive, resistive, and electromagnetic types. Among them, the capacitive touch panel uses human fingers to touch the surface to form capacitive sensing. Please refer to FIG. 1 , which is a schematic diagram of a conventional finger-operated capacitive touch panel and a sensing unit of the capacitive touch panel. The structure composition of the conventional finger-operated capacitive touch panel and the sensing unit of the capacitive touch panel is shown in the figure. In this embodiment, for example, the capacitive touch panel has a basic capacitance value when it is not touched. When the operator touches the capacitive touch panel 12 wi...
