Pen type input device with stylus pen

The invention relates to a pen type input device with a stylus pen, in particular to a pen type input device which has the functions of input and stylus and can avoid interference when the wireless module works.

After the advent of electronic products with full touch interface, such as smart phones and tablets, there was a useless use of the stylus. The main argument is that the full touch interface provides intuitive operation and can be operated directly with fingers. The pen seems to be useless. However, according to the actual experience of consumers, there is a considerable degree of overturning of the above statement. This is because the finger has a high friction coefficient when it is in direct contact with the touch panel, which is not conducive to long-time writing. On the other hand, using a stylus Writing is also closer to handwriting habits. Based on the above factors, the stylus has a tendency to go against the trend.

Although the practical value of the stylus has been affirmed, there are many pen-type input devices related to computer operation. In addition to the stylus, there are digital pens and optical pen-type input devices that are used with the digital tablet. The pen-type input devices are each a separate product, and there is pressure on the economy or management for consumers who have such pen-type input devices. Since all of the foregoing input devices are presented in a pen type, which is in the form of a "pen", that is, the opposite ends are available for use, so that the stylus, the optical input device are provided at both ends of the "pen", or The possibility of a stylus and a digital pen. It can be seen from the above that the integration of various pen-type input devices and stylus is theoretically feasible, but implementation has to consider their respective characteristics and interference due to integration. problem.

First of all, for the stylus, a pen made of conductive rubber is mainly provided at one end of the pen, so that the user can electrically contact with the pen when holding the stylus, and generally has conductivity. The metal material is made into a pen holder, and when the user holds the pen holder, the pen holder and the pen tip form an electrical contact. Therefore, the traditional stylus pen must be partially or completely made of metal, which is a necessary technical means.

However, for the optical pen type input device, the metal pen holder is harmful, because the optical pen type input device contains a wireless module, and when the pen holder is made of a conductive metal, the signal to the wireless module is Transmission causes interference. Similarly, when the pen type input device has a built-in wireless charging module, if the pen holder is made of conductive metal, it will also interfere with its charging operation.

It can be seen from the above that when the pen type input device has a built-in wireless module and/or a wireless charging module, the pen holder cannot be made of a conductive metal material to avoid interference with signal transmission or charging operations. However, the stylus must have a metal pen to be used normally, and thus the structure of the pen-type input device is in conflict with each other. Therefore, in order to effectively integrate the stylus and the pen-type input device, an effective solution to the above contradictions and conflicts must be proposed. .

Therefore, the main object of the present invention is to provide a pen type input device with a stylus pen, which can effectively solve the mutual repulsion between the stylus pen and the pen type input device in the pen holder structure, and effectively integrate the stylus pen on the pen type input device. To provide pen type input and stylus function respectively.
