Problems solved by technology

[0006] However, the known and above described stylus has various disadvantages
[0007] These pens are expensive to make
Almost all of these input pens according to the prior art are available as ballpoint pens, whereby the user is very limited in his choice

Embodiment Construction

[0075] figure 1 An input device 1 is shown, which is designed as a refill pen 11 . In this embodiment, the lead 112 extends over the entire cross-section of the pen 11 . The contact element 12 is arranged on the end of the device 1 opposite the writing point 117 . The contact elements 12 are held by undercut connections / protrusions 115 . In this exemplary embodiment, the lead 112 as well as the contact element 12 , which is present here as a foam / rubber body or as a rubber-elastic body 121 , are electrically conductive. In an application not shown, the user touches the input device to the surface of the tablet computer and thus establishes an electrically conductive connection between the tablet and the user's hand. This contact causes a delay in charging, thereby triggering an input function on the tablet or tablet computer.

[0076] The use of contact elements 121 facilitates the surface of the plate, for example preventing scratches. However, the contact area between ...

Abstract

The invention relates to an input device (1) for capacitive, touch-sensitive displays, said device being a simple stylus (11) that is designed to be sharpened. The device is in the form of a lead / refill, or of a lead / refill with a coating, or of a lead / refill with a casing, or the device has a lead / refill, a casing and a coating, said lead / refill, casing and / or coating being electrically conductive. An element forming a contact element (12) for a tablet / display is located on one end of the device, an electrically conductive material constituting said contact element.

Description

technical field [0001] The invention relates to a stylus for a so-called touch-sensitive capacitive screen according to the preamble of claim 1 and its use. Background technique [0002] Input devices for such displays are known in principle. [0003] For example, stylus pens are known which are formed from an electrically conductive handle, in which a soft, conductive, resiliently formed contact plug for the screen or the screen surface is formed at one end. [0004] The disadvantage of such stylus is that they are too expensive as a pure stylus and also do not fulfill the writing or drawing function. [0005] In addition, there are stylus pens which have a writing mechanism or applicator at one end and conductive means in the form of contact plugs on the other side which, when in contact with the capacitive screen, are able to Realize or trigger the input function. [0006] However, the known and described above stylus has various disadvantages. [0007] These pens are...
