New type description [Technical field to which the new type belongs] This creation relates to a miniature cursor controller, especially a miniature cursor controller that can collect and output the relative displacement information between the location and a measured object. [Previous technology] The electronic products that individuals carry are changing with each passing day, and the number of models equipped with display screens is gradually increasing. However, due to the limitation of command input methods, it is often necessary to use the menu method to select layer by layer. 'Like a computer, there is no mouse to be free on the screen The mobile cursor is controlled, so it is cumbersome to operate. It is impossible to use direct access and deeper functions. With the increasing display screen of portable electronic devices, it is necessary to find more convenient cursor control devices. At present, the cursor input method of personal electronic products is mainly using the directional buttons or touch with a finger or a pen. Among them, when the directional buttons are used, it often requires multiple presses to move to a specific position. Pressing with your finger or pen on the screen will not only easily pollute and damage the screen, less precise control, obstructing part of the line of sight, and the cost of the screen will be 1¾. The human-machine interface optical mouse is very important in computer use today. Since the development of the M283242 tool, it has basically used a light-emitting diode as a source since :: The optical component guides the light to the plane to be measured, and then uses an image sensor to capture the image of the plane to be measured at high speed, and compares the relative displacement of the image content to obtain relevant information about the movement of the mouse, and then move On-screen indicators to exercise control
功能。另外也有雷射光學滑鼠，其係以單獨設置的面 射型半導體雷射彳令糸 作為先源，經獨立的光學鏡頭照射到 待測平面，並以一影像感測器高速地攝取待測平面之 影像，並比較影像内容的相對位移，來獲取滑鼠移動 的相關訊息’進而移動銀幕上的指標來遂行控制的功 能，而使用雷射作為光源的優點是利用雷射光的高度 平行及單-波長的特性，可以獲得較清晰的影像，因 此可以大幅提昇影像内容相對位移的精確性，進而提 升滑鼠的控制準確度。 而目别的發光二極體滑鼠有一些是將發光二極體 與影像感測元件分別封裝，或是在某些產品上，是將 發光二極體與影像感測晶片封裝在同一封裝體内。另 外，雷射光學滑鼠則是將雷射晶片與影像感測晶片分 別封裝’而且所使用的早 疋波長850奈米的面射型雷 M283242 射疋屬於不可見光範圍，不但成本較邊射型雷射 冋而且照射入人眼時無法察覺，因此有潛在的安全 顧慮另外匕們都要使用一組外加的光學鏡頭；其中 一部份將光源指向特定區域，另一部分導引反射回的 光、、泉，經聚焦後在影像感測晶片上形成清晰的影像， 以便加以辨識處理。Features. In addition, there is also a laser optical mouse, which uses a separately set surface-emitting semiconductor laser command as a source, irradiates the plane to be measured through an independent optical lens, and uses an image sensor to capture the test to be measured at a high speed. Plane images and compare the relative displacements of the image content to get the relevant information of the mouse movement, and then move the indicators on the screen to perform the control function. The advantage of using laser as the light source is to use the high parallel and single -The characteristic of the wavelength can obtain a clearer image, so the accuracy of the relative displacement of the image content can be greatly improved, thereby improving the control accuracy of the mouse. Some of the light-emitting diode mice are packaged separately from the light-emitting diode and the image sensing element, or on some products, the light-emitting diode and the image sensing chip are packaged in the same package. Inside. In addition, the laser optical mouse encapsulates the laser chip and the image sensing chip separately, and the surface-emission type laser M283242 with an early-beam wavelength of 850 nanometers belongs to the invisible light range, which is not only more expensive than the edge-emission type. Lasers are irritated and undetectable when irradiated into the human eye, so there is a potential safety concern. In addition, daggers must use an additional set of optical lenses; one part points the light source at a specific area, and the other guides the reflected light. , Quan, after focusing, a clear image is formed on the image sensing chip for identification and processing.

Therefore, the optical mouse is not practical. The optical engine is miniaturized and integrated with personal portable electronic devices, and can be used very conveniently. It should have extremely high practical value. The measured planes detected by the optical engine of the conventional optical mouse 7 have a spatial distance from the optical guide f 71, and this distance is maintained through a diaphragm 72 with an aperture, as shown in the fourth figure This dream with a cavity structure is used.), When the lunar plane is always down, contact with the desktop, foreign objects and pollution are less likely to invade, so it can be used, if you want to turn this optical engine up When installing the electronic device with you, “the open aperture is easy to be penetrated by dust” and it is not easy to maintain the distance from the object to be measured. Therefore, it is inconvenient for the M283242 to use the 0 port. The reflected light from the object under test is collected and reflected back to the sensor for calculation, and the sensor package is optimized for use, the packaging volume is reduced, the cost is reduced, and how to compare it with Gu Yi is the basis for this. Creative issues need to be solved. [New content] Based on the above, the main purpose of this creation is to provide a light-emitting chip as a maggot and an image-sensing chip as a receiver. Information on the movement of the image formed by the object on the other side pressed against the light-transmitting mirror window, and a miniature cursor controller with a simplified packaging process, reduced packaging volume and reduced cost. In order to achieve the above purpose, the miniature vernier controller of this creation is composed of a herd, a light-emitting chip, an image-sensing chip, a grating, a Zener diode, and an optional computing chip. The packaging system has a base, and a structural cover is provided on the base. A light guide device and a light-transmitting mirror window are provided at the selected position of the cover. The light-emitting chip is combined on the base, and the illumination light is guided to the base. After the detection surface of the mirror window, an image formed by irradiating an object adjacent to the other side of the transparent mirror window and pressing on the transparent mirror window, an image sensing chip is used to sense the pattern generated by the reflection of light M283242. When detected, there is a horizontal displacement 犄, which can provide an output signal of relative displacement. Advancement-the shortest optical path formed by the image sensor chip and the light emitting chip located adjacent to each other, especially in order to obtain a strong reflection signal, the entire structure of the ancient # π m, ^ structure ^ The degree is reduced, and the same light-mirror window that the emitted light and the return information share also makes the structure simple and economical. And the single package structure formed by the miniature displacement sensor used to search for the poor sound of the measured object in this creation can also achieve the special effects of simplified process, reduced packaging volume and reduced cost.

Among them, the outer lead 11 of the US seat 11 can be composed of metal wires or lead terminals, etc. The light emitting chip 2 can be a light emitting diode or a laser diode, and can be one or more The auxiliary body with a refractive function is combined and combined with the base of the package body 1 and is electrically connected on the base 1 and sealed by the cavity 121 of the cover 12, and the light emitting end (face) thereof is correspondingly located with the refractive power. The incident end of the light guide structure 122 of the function, the deflected light is guided to the detection surface 124 of the transparent mirror window 123 and is incident on the measured object 50 next to this surface and then detected on the surface 24. The resulting image. The image sensing crystal 3 is a 10 M283242 chip (Image Sensor Chip) for receiving sensing images, which is combined with the position of the projection of the reflected light received on the base 11 of the package 1 according to the above-mentioned transparent mirror window ^ 23 The chamber 1 21 which is electrically connected and is covered by a cover 12 is sealed with a sealed 'image sensing wafer 3'.

In addition, the transparent lens window 123 can also be integrated with the imaging lens 125 through optical design to simplify the structure, or in some applications, only the principle of pinhole imaging can be used to achieve partial efficiency. One of the applications of this creation "Miniature Cursor Controller". Because of the structure's resistance to static electricity, the light-emitting chip 2 has some structures. A Zener diode 6 can be installed near the light-emitting chip, and its polarity is opposite to that of the light-emitting crystal M 2. The connection is to be positively placed, and the component may generate electrostatic charges during use to avoid 12 M283242 damage to the light-emitting chip. Since the measured object 50 of this structure needs to be close to the detection surface 124 of the light-transmitting mirror window 123, in order to prevent the surface 124 from being scratched or worn after using for a period of time, it can be adhered or combined as needed. First, Tian Erke replaces the film (not shown) to protect the integrity of the detection surface 124. …… " The light-emitting chip 2 and image sensing chip 3 and transparent mirror window 123 of the "mini-cursor controller" are all packaged as a single component, so the packaging process can be simplified. With the addition of optical lenses in province D, the height of the entire group of structures can be reduced to less than 5 cm. Under the trend of sophisticated design of current electronic products, J and J can achieve the effect of reducing the packaging volume. The scope of application 'does meet the needs of the industry. / Zonghe mentioned above, this creation "Miniature Cursor Controller", broken energy I said from the above structure, to achieve the "expected effect" and has not been seen in the publication before the application nor disclosed, in line with the new head of the new, search for harmony , Progress, and compliance with the industrial availability, etc., Yi Du Du also benefited.
