Description

A kind of Ji ?the machine input media

The utility model belong to Ji ?the peripherals of machine, particularly belong to Ji ?the input equipment of machine, refer to especially in handwriting mode Xiang ?machine tablet pattern, literal and Kong Zhi Ji ?on the machine screen cursor De Ji ?the machine input media.

Along with popularizing and the widespread use of window system of PC, Kong Zhi Ji ? the device of cursor on the machine screen almost become the device of the indispensability of one of staff.Supply in the market mainly is the boxlike mouse in the device of control cursor, and trace ball is less, and pen type mouse is rare.The boxlike mouse is to hold on worktable or mouse pad slippage with palm to control cursor; Trace ball is to stir spin with finger to control cursor, and Qi You Dian is that required work top scope is little, and trace ball can be taken from worktable work, thereby long-term work is difficult for causing arm fatigue; Pen type mouse then be as pen with finger holding in ways of writing control cursor and Xiang ?machine tablet pattern, literal and signature, Qi You Dian is the use habit that meets people's routine.The patent of pen type mouse had just been announced before first boxlike mouse product in 1985 comes out, the patent of the various pen type mouses of various countries' announcement now is innumerable, the imagination of numerous pen type mouses is based on spin and drives the structure that grating wheel (or optical encoder wheel) taken turns or driven with spin to potentiometer, U.S. Patent No. 5210405, No.5291213 and Chinese patent application number 00219764,00219887,00258363,01212629,01246861 or the like for example, this mechanical structure are difficult to produce the mouse of thickness as the pen.The imagination of another kind of optical pen mouse is to be provided with light source and optical sensor within it, its principle of work is: with the variation of the motion of the catoptrical optical characteristics of auto-correlation manner of comparison testing face (the reflecting surface reflection contained as reflected light) random notes, judge the direction of motion and the move distance of pen, for example U.S. Patent No. 3182291, No.4279465, No.4475240, No.5027115, No.5635956 and Chinese patent application numbers 96218723,98802502,99101715,01227790,01802379 or the like, wherein with optical fiber and all be to be made into thickness as the common pen without optical fiber.But because the custom that the boxlike mouse product that appears on the market has the earliest been turned out the user has been used to the boxlike mouse when operation and has been come to feel uncomfortable on the contrary with pen type mouse again.And, for long-term controlling cursor, controlling the boxlike mouse that is placed on the worktable can be freer random than the pen type mouse of controlling finger grip, be difficult for causing that finger is tired because control the boxlike mouse, this be why with finger hold a pen write one day word can be than the reason outside the more tired psychological factor of one day computer of object for appreciation.Though pen type mouse has remarkable advantages than boxlike mouse and trace ball on functions such as signature, picture, the tiny character of input, the pen type mouse product is rare.

Along with popularizing of portable notebook computer and PDA (personal digital assistant), and the appearance of the new-type plate type computer that integrates display screen and computer main part, more and more urgent to the demand of pen type mouse.Touch screen pen that is attached to PDA and plate type computer now or the induction pen (light pen) that receives energy of electromagnetic field are directly operated on display screen, have had pen type mouse just can replace now touch screen pen and induction pen.Excellent Dian with pen type mouse no longer directly operates on display screen, also can the abrasion display screen thereby neither can block displaying contents.Future can be more and more many with the people of pen type mouse operating computer predictably, but present most people more get used to coming operating computer with boxlike mouse or trace ball.The pen type mouse design of existing patent has a common De Que Dian, all is the operating habit that can't satisfy present majority, therefore can't penetration and promotion.It seems, from a kind of transitional period of being accustomed to the another kind custom, need a kind of not only can be used as pen type mouse with but also can be used as the product of boxlike mouse (or trace ball), that is to say, can satisfy the custom requirement of people's operation boxlike mouse (or trace ball) now, can change pen type mouse into and come work needing to sign, draw and import little occasions such as character again.Especially for the people who begins to learn computer, directly come operating computer also more to meet it and be easy to left-hand seat with the custom of pen at ordinary times with pen type mouse.

The idea of one-object-many-purposes has it from ancient times: U.S. Patent No. 4562347 has been announced a kind of computer inputs with mouse and two kinds of functions of trace ball, a hole is respectively opened at the bottom of its shell and top, the part ball surface of cased roller ball can be protruded in the outside of bottom and top-portion apertures, the cased both sides near roller ball of displacement transducer.This device be placed on the desktop then roller ball by the Kong Keyu desktop contact of bottom frictional rotation, as common mouse; This device then can be controlled roller ball with finger by the hole at top by hand-held unsettled, as trace ball.Chinese patent application numbers 92238143 also proposes a kind of multiduty computer inputs, its enclosure designs gets and can hold, roller ball is installed in the exposed division bulb separation surface, the top of shell, the photometry rotating disk group of roller ball friction gearing both sides, assembly such as mounting circuit boards and switch under the roller ball.But this device reverses direction allows roller ball up or down, when the roller ball available finger that makes progress is stirred it and made the trace ball purposes, when roller ball can be used as common mouse by friction rolling downwards on desktop or mouse pad, roller ball rolls on the table and also can be envisioned as a huge ball pen of writing, so the designer is again from being called the track pen.Y-axis can be reversed phase place because of upwards with downward reverses direction the time, responds correct roller ball sense of displacement in both cases in order to make cursor, has used the switch of switching direction in the circuit.This patented method in fact also is making progress with dual-purpose downwards of same roller ball, is two kinds of using method of a trace ball in other words.More than two devices all be a roller ball not only done mouse with but also make trace ball and use, with demand not only can be used as pen type mouse with but also to can be used as the product of boxlike mouse (or trace ball) different, because with boxlike mouse (or trace ball) two different displacement input heads (sensor that it is inner and circuit may be shared) must be arranged as pen type mouse, can not only make the input head of pen type mouse but also make the input head of boxlike mouse (or trace ball) with same roller ball.The patent 92238143 device Bei Let Meter people track pen of calling oneself, The device have been used mechanical parts such as photometry rotating disk group and volume is thick, fundamentally just do not have the feature with the common pen of finger grip, and its said track pen can only be the pen on the imagination meaning.

In order to overcome the deficiency in the existing pen type mouse patent design, satisfy pen type mouse and the dual-purpose demand of boxlike mouse (or trace ball) one, the technical solution of the utility model is a kind of optical pen mouse to be integrated into people used on accustomed boxlike mouse or the trace ball.Select for use optical mouse IC to make said integrated dual-purpose apparatus, be in order easily the pen type mouse in the dual-purpose apparatus to be made into thickness as the pen, boxlike mouse in the dual-purpose apparatus or trace ball then are not defined as optics boxlike mouse or optics trace ball, but preferably optics boxlike mouse or optics trace ball are because can reduce cost with the shared optical mouse IC of pen type mouse like this.Concrete technical scheme is as follows:

Computer input unit of the present utility model constitutes by shell, button, light source, pcb board, imaging system, imageing sensor and signal Processing and control IC and with the transfer member that wired or wireless mode is linked to computing machine, it is characterized in that: said computer input unit integrates optical pen mouse and boxlike mouse (or optics trace ball), except can carrying out common boxlike mouse (or optics trace ball) operation control cursor, also available finger grip is with handwriting mode tablet pattern, literal and signature.This most preferred embodiment of shell that integrates the device of optical pen mouse and boxlike mouse (or optics trace ball) is to be made into the shape with (or as major part ball pen) as the similar mouse.The head of this mouse shape shell (or thin end of form of a stroke or a combination of strokes shell) be one section gradually thin sleeve be suitable for mother refer to, middle finger and forefinger gripping and writing, the nib that is installed in the optical pen mouse pen core in the gradually thin sleeve can expose from the thinnest end of sleeve.The transmittance that the window that light-permeable is arranged on the nib of this optical pen mouse pen core, this window can allow the interior light source of gradually thin sleeve send goes out, and can allow the reflected light transmission of writing workplace enter in the gradually thin sleeve again.

This belly of mouse shape shell that integrates optical pen mouse and boxlike mouse is wide slightly and smooth.Be provided with the window of boxlike mouse in the nearly center of mouse shape shell belly, but the boxlike MouseAcross is crossed the displacement that this window and workplace lotus root are closed perception shell opposite working.There is the radian of the projection of the palm that is fit to let go at the back of this mouse shape shell, this mouse shape case back near the tail end place left button and the right button of mouse are installed at least, transfer member is installed in the afterbody of mouse shape shell.
