Description

The pen type optical input device

Technical field

The utility model is relevant for a kind of peripheral input media, particularly a kind of pen type optical input device.

Background technology

Science and technology develops fast with progressive in recent years, no matter be personal computer (Personal Computer, PC) or mobile computer computer equipments such as (Notebook), become masses' indispensable portable tool in daily life or work, yet computer equipment must be by as pointer input devices such as mouse, Trackpad, trace balls, the controlling of window interface that could object computer equipment.

With the optical mouse is example, the optical mouse of at present common hemispherical dome form only limits to use on traditional mode, and because external form and volume are too huge, make the user can't operate as the mode that holds a pen at all, thereby generation use dead angle to a certain degree, and commonly use hemispherical dome-shaped optical mouse in the design of structure and shape, also cause many awkward problems.In order to solve the above problems, manufacturer has begun to provide the optical mouse of pen type structure on market, so that user's holding operation is complied with the ergonomics custom that grips penholder originally.
