M318156 八、新型說明： 【新型所屬之技術領域】 本創作係有關一種多光源滑鼠，特別是關於一種可適用於不透 光的反射表面及透光的玻璃表面之多光源滑鼠。 【先前技術】 隨著科技進步與使用者的需求曰益增多，電腦滑鼠(mouse)的解析度 厂 （res〇luti〇n)不斷提高，例如從800 dpi(dot per inch)提高到1600 dpi，對使用 者而言，尤其是電腦遊戲(game)、電腦輔助設計(Computer-Aided Design， CAD)及電腦辅助製造(Computer-AidedManufacturing，CAM)的使用者，他 們常常需要使用將畫面推近或拉遠(zoom)的功能，因此往往使用者已經移 動滑鼠一段長距離，但螢幕上的游標(cursor)卻只移動一段短距離，因為此 時滑鼠已離使用者太遠，所以使用者需將滑鼠移近身體以方便繼續移動滑 鼠來控制游標，所以目前的滑鼠均具備一項功能，亦即當滑鼠被舉離桌面 時，螢幕上的游標維持固定不動，因此使用者只要將滑鼠舉離桌面即可自 由地將滑鼠移近身體以方便繼續移動滑鼠來控制游標。 | 習知之光學滑鼠(optical mouse)使用發光二極體(Light Emitting Diode， LED)作為光源，發光二極體的發散角(divergenceangie)較大，所以能量較 發散，因此當滑鼠被舉離桌面時，收光元件不會接收到足夠的能量以產生 控制游標的信號，所以螢幕上的游標能夠維持固定不動，達到當滑鼠被舉 離桌面時游標不會漂移(drift)的目的。 然而’習知之雷射滑鼠(laser mouse)使用雷射二極體(Laser Di〇de， 作為光源，雷射二極體的發散角比發光二極體小，能量較集中，因此當滑 鼠被舉離桌面時，收光元件仍可能接收到足夠的能量以產生控制游標的信 號’所以螢幕上的游標可能會產生漂移的現象。 5 M318156 因此’有些習知之雷射滑鼠的光源入射端使用一聚光透鏡(f0Cusing lens)把雷射二極體發出的雷射光聚焦到桌面，且反射光接收端使用一收光 透鏡(receivinglens)把反射光聚焦到一收光元件；當滑鼠被舉離桌面時，此 種結構可使螢幕上的游標不會產生漂移的現象。 另一方面’人們對滑鼠的功能要求也越來越高，不但要求滑鼠必須 能在一般的桌面操作，也希望同一滑鼠能在玻璃表面操作，因為玻璃能被 光線穿透且具有厚度，而發光二極體的發散角大，能量較發散，所以並不 適用於作為在不透光的反射表面以及透光的玻璃表面皆能操作之滑鼠的 光源，而雷射二極體的發散角較小，能量較集令，如果收光元件的接收孔 徑(acceptance aperture)足夠大，則雷射二極體可適用於作為在不透光的反 射表面以及透光的玻璃表面皆能操作之雷射滑鼠的光源，但此種結構可能 會導致當滑鼠被舉離不透光的反射表面或透光的玻璃表面時，螢幕上的游 標產生漂移的現象。 相對的’前述之使用聚光透鏡與收光透鏡的雷射滑鼠雖然不會產生 滑鼠被舉離桌面時游標漂移的現象，卻不能滿足在不透光的反射表面以及 透光的玻璃表面皆能操作的需求。 因此，習知之光學滑鼠及雷射滑鼠無法同時滿足既要適用於不透光 的反射表面以及透光的玻璃表面，而且滑鼠被舉離不透光的反射表面或透 光的玻璃表面時游標不能漂移的要求。 【新型内容】 為解決上述習知之光學滑鼠及雷射滑鼠無法同時滿足既要適用於 不透光的反射表面以及透光的玻璃表面，而且滑鼠被舉離不透光的反射表 面或透光的玻璃表面時游標不能漂移的問題，本創作目的之一係提供 一種多光源滑鼠，既可適用於不透光的反射表面以及透光的玻璃表面， 而且當滑鼠被舉離不透光的反射表面或透光的朗表面時，制發幕上的 游標維持固定不動，不會產生游標漂移的現象。 6 M318156 本創作目的之-係提供一種多光源滑鼠，其包括聚光透鏡或收光 透鏡以增進影像感測元件(image sens〇r)的感光效率。 本創作目的之一係提供一種多光源滑鼠，其包括至少一遮板 (shiddingp㈣以確保當滑鼠被舉離不透光的反射表面或透光的玻璃表面 時不會產生游標漂移的現象。 本創作目的之-係提供—種多光源輯，其包括—光感測器 (photo detector)’用以接收部分反射光作為自動控制光源之輸出功率的基 準。 本創作目的之-係提供—種多光源滑鼠，其包括—手動開關 (manual switch)，用以讓使用者選擇滑鼠的應用是在不透光的反射表面或 是在透光的玻璃表面。 本創作目的之-係提供—種多光源滑鼠，其包括—自動開關 (automatic switch)，用以自動偵測滑鼠的應用是在不透光的反射 在透光的玻璃表面。 / 為了達到上述目的，本創作-實施例之多光源滑鼠包括：一第 一光源，一第二光源，其設於第一光源之同側，其中，第一光源發出 之-第-人射光與第二光源發出之_第二人射光分別以不同的入射 角入射至一不透光的反射表面，並形成一第一反射光與一第二反射 光；及一影像感測元件，其設於第一光源與第二光源之相對側，影像 感測元件係用以接收第-反射光或第二反射光以產生控制—電腦榮幕游 標的信號。 底下藉由具體實施例配合所附的圖式詳加說明，當更容易瞭 解本創作之目的、技術内容 '特點及其所達成之功效。 M318156 【實施方式】 詳細說明如下，所述較佳實施例僅做一說明而非用以限定本 創作。 第1圖是本創作一實施例之一多光源滑鼠2應用於一反射表面4的 示意圖，如圖所示，反射表面4係指不透光的表面，包括木質桌面、紙質 表面及塑膠墊片等表面；多光源滑鼠2包括：一第一光源6;

New Description: [New Technology Field] This creation is about a multi-light source mouse, especially for a multi-light source mouse that can be applied to a light-reflecting reflective surface and a light-transmissive glass surface. [Prior Art] As the advancement of technology and the needs of users increase, the resolution of the mouse mouse (res〇luti〇n) continues to increase, for example, from 800 dpi (dot per inch) to 1600 dpi. For users, especially users of computer games, Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM), they often need to use the screen to zoom in or The function of zooming, so the user has already moved the mouse for a long distance, but the cursor on the screen only moves for a short distance, because the mouse is too far away from the user, so the user The mouse needs to be moved closer to the body to continue to move the mouse to control the cursor, so the current mouse has a function, that is, when the mouse is lifted off the desktop, the cursor on the screen remains fixed, so the user Simply lift the mouse off the table and move the mouse closer to the body to continue moving the mouse to control the cursor. The optical mouse uses the Light Emitting Diode (LED) as the light source, and the divergence angle of the light-emitting diode is large, so the energy is more divergent, so when the mouse is lifted off On the desktop, the light-receiving component does not receive enough energy to generate a signal that controls the cursor, so the cursor on the screen can remain stationary, so that the cursor does not drift when the mouse is lifted off the desktop. However, the 'laser mouse' uses a laser diode (Laser Di〇de) as the light source. The divergence angle of the laser diode is smaller than that of the light-emitting diode, and the energy is concentrated. Therefore, when the mouse is used, When lifted off the table, the light-receiving component may still receive enough energy to generate a signal that controls the cursor' so the cursor on the screen may drift. 5 M318156 Therefore, some of the familiar laser mouse's light source is incident. Using a condensing lens (f0Cusing lens) to focus the laser light emitted from the laser diode onto the table top, and the reflecting light receiving end uses a receiving lens to focus the reflected light to a light collecting element; when the mouse is When lifting off the table, this structure can make the cursor on the screen not drift. On the other hand, 'the function of the mouse is getting higher and higher, not only the mouse must be able to operate on the normal desktop. It is also hoped that the same mouse can be operated on the surface of the glass, because the glass can be penetrated by light and has a thickness, and the divergence angle of the light-emitting diode is large, and the energy is relatively divergent, so it is not suitable for being used as an opaque light. Both the reflective surface and the light-transmissive glass surface are capable of operating the mouse light source, while the laser diode has a smaller divergence angle and a higher energy distribution. If the receiving aperture of the light-receiving element is sufficiently large, then the lightning The emitter diode can be used as a light source for a laser mouse that can operate on both the opaque reflective surface and the light transmissive glass surface, but this structure may cause the mouse to be lifted away from the opaque reflection. On the surface or the surface of the light-transmissive glass, the cursor on the screen drifts. The opposite 'the aforementioned laser mouse using the condenser lens and the light-receiving lens does not cause the cursor to drift when the mouse is lifted off the table. Phenomenon, but can not meet the needs of the opaque reflective surface and the transparent glass surface can be operated. Therefore, the conventional optical mouse and laser mouse can not meet the reflective surface that is suitable for both opaque and The transparent glass surface, and the cursor cannot be drifted when the mouse is lifted away from the opaque reflective surface or the transparent glass surface. [New content] To solve the above-mentioned optical mouse The laser mouse cannot satisfy the problem that it is suitable for both the opaque reflective surface and the transparent glass surface, and the cursor cannot be drifted when the mouse is lifted away from the opaque reflective surface or the transparent glass surface. One of the creative purposes is to provide a multi-source mouse that can be applied to both opaque reflective surfaces and light transmissive glass surfaces, and when the mouse is lifted away from an opaque reflective surface or a translucent surface. The cursor on the screen remains fixed and does not cause drift of the cursor. 6 M318156 The purpose of this creation is to provide a multi-source mouse that includes a condenser lens or a light-receiving lens to enhance the image sensing element (image) Sensing efficiency of sens〇r) One of the objects of the present invention is to provide a multi-source mouse that includes at least one shiddingp (four) to ensure that when the mouse is lifted off the opaque reflective surface or the light transmissive glass surface There is no drift of the cursor.

In addition, the multi-source mouse of the creation may include at least one shutter to ensure that the cursor does not drift when the mouse is lifted off the opaque reflective surface or the transparent glass surface. Figure 5 is the creation. A multi-source mouse 42 of an embodiment is applied to the reflective surface 4.

Since the image sensing element 10 does not receive enough light to generate a signal for controlling the cursor, the cursor on the computer screen remains stationary and does not cause drift of the cursor. It is known to those skilled in the art that the setting of the shutter is to ensure that the slider does not drift when the mouse is lifted away from the opaque reflective surface or the light transmissive glass surface, as long as the M318156 looks like a stalk. 'There is no need to set the shutter to achieve the same purpose, so the size, shape and quantity of the shutter are not special. Therefore, the patent of this creation (4) covers the multi-light mouse with no cover and has various sizes and miscellaneous A multi-light mouse with a number of shutters.
