M396603 五、新型說明： 【新型所屬之技術領域】 本新型關於-種清潔片，尤指一種光碟機光學拾訊頭 之清潔片。 . 【先前技術】 光碟機（BD/DVD/CDPlayer)於儲存或使用時，有時會 目灰塵或其他異物侵人，污染其光學拾訊頭，導致發生讀 取訊號不良或無法言買取的情形，而需以清潔器將該光學拾 訊頭清潔乾淨。 一般的光學拾訊頭清潔器，係於—仿如光碟片的片體 上植入刷體，當光學拾訊頭通過刷體時，以刷體對光學拾 訊頭進行清潔動作。 第1圖及第2圖係繪示習知光學拾訊頭清潔片的剖視 圖及清潔動作示意圖。如圖所示，習知光學拾訊頭清潔片 φ 300儲置有與一般光碟片相似的訊號，並於片體31〇由其第 -一面311至相對的第二面312垂直貫穿設有一固定孔313 ’ 用以植設一刷體束320 ;即，刷體束320係植設固定於片體 310的整個厚度後，向第二面312的方向突伸。當光碟機的 光學拾訊頭200通過刷體束320時，刷體束320的端部接觸 到光學拾訊頭200，並以位於第二面312之固定孔313的内 緣為支點314而彎折。然而，該支點314極為靠近光學拾訊 頭200 ’即該支點314距離光學拾訊頭200較短，使得刷體 束320以此支點314彎折後接觸到光學拾訊頭200時會產生 3 M396603 較大的阻力，而此過大的接觸阻力會對光學拾訊頭200造 成損傷；尤其對於波長較短的藍光拾訊頭（BD Laser Lens) 而言，其拾訊頭與光碟片間之距離更短，因此刷體束320 以支點314彎折後所產生的阻力更大，因而對其拾訊頭200 的損傷更為明顯；而且，過大的接觸阻力亦會造成清潔片 300的偏移，導致光碟機無法讀取清潔片300所儲置的訊號 或斷訊等不良情況，使得清潔動作不佳或無法清潔。 • 由於以上原因，造成習知光學拾訊頭清潔片的應用性 • 不佳。 【新型内容】 本新型之目的在於提供一種光碟機光學拾訊頭之清 潔片，可大幅減少清潔時產生的阻力，並可確實且輕易地 清潔光碟機的光學拾訊頭。 本新型之另一目的在於提供一種應用性佳之光碟機 光學拾訊頭之清潔片。 根據上述目的，本新型之一態樣是在提供一種光碟機 光學拾訊頭之清潔片，其具有一與一般光碟片同樣大小並 儲置有訊號的片體，片體具有一中心安裝孔，且片體具有 相對的一第一面與一第二面；片體以至少一二階孔部裝設 有至少一刷體束；其中，二階孔部包括相連通的一嵌固細 孔與一同心擴孔，嵌固細孔設於片體的第一面，同心擴孔 形成於片體的第二面；刷體束由多數的刷體集結而成，刷 體束包括相對的一根部與一端部，根部嵌固於嵌固細孔， M396603 端部經由同心擴孔朝向片體之第二面的方向突伸。當刷體 束清潔光學拾訊頭時，刷體束以第一面之嵌固細孔的内緣 為支點而彎曲，並進入作為活動區的同心擴孔；刷體束的 支點變遠同時彎曲的刷體束的阻力減少，減少刷體束對於 光學拾訊頭的擦拭阻力及擦拭損傷；而且清潔片的平面偏 移量變小，錯誤訊號減少，而能正常讀取及正常清潔。 根據本新型的一實施例，同心擴孔為一錐形或圓形的 ' 同心擴孔，使得刷體區有一較大的活動區。 • 根據本新型的一實施例，片體所設之刷體束為多數且 為間隔設置，而且各個刷體束至中心安裝孔各為不同的半 徑距離，而可據以在清潔時分別接觸到光學拾訊頭的不同 部位，使其清潔更為完備。 根據本新型的一實施例，第一面為清潔片的訊號面， 其上覆有一印刷面，第二面為清潔片的一讀取面，用以由 第二面讀取清節片的訊號。 【實施方式】 有關本新型之前述及其他技術内容、特點與功效，在 以下配合參考圖式之較佳實施例詳細說明當中，將可清楚 的呈現。 參閱第3圖至第5圖，其分別繪示依照本新型一實施式 之光碟機光學拾訊頭之清潔片的仰視圖、剖視圖及主要部 份的剖視放大圖。 如圖所示，依照本新型一實施式之光碟機光學拾訊頭 5 M396603 之清潔片100 ’具有一與一般光碟片同樣大小並儲置有訊 號的片體110，片體110具有一中心安裝孔113，用以使用 時女裝於一光碟機（未圖示）的一轉盤上；且片體H0具有 相對的一第一面111與一第二面112,在實施上，第一面U1 為清潔片loo的訊號面，其上覆有一印刷面，第二面112 則為清潔片100的一讀取面，用以讀取訊號面所儲置的訊 號。 依照本新型一實施方式之清潔片100，其設計重點在 • 於，片體110以至少一二階孔部120(附圖的實施例係顯示 具有二個二階孔部）裝設有相對應數量的刷體束13 0 (附圖 的實施例係顯示具有三個刷體束）。其中，二階孔部i 2〇 包括相連通的一嵌固細孔丨21與一與該細孔同圓心的同心 擴孔122例如錐形的同心擴孔；嵌固細孔121設於片體u 〇 的第一面111，而同心擴孔122則形成於片體11()的第二面 112，因此同心擴孔122在第二面112的孔徑明顯大於嵌固 φ 細孔121在第一面111的孔徑。 刷體束13 0由多數的刷體集結而成。刷體束13 〇包括相 對的一根部131與一端部132，其中，根部131嵌固於二階 孔部12 0的嵌固細孔121 ’端部13 2則經由二階孔部12 〇的同 心擴孔122而朝向片體110之第二面ip的方向突伸。同心 擴孔122乃形成一可讓刷體束130活動於其間的活動區。 請一併參閱第6圖，其繪示依照本新型一實施方式之 光碟機光學拾訊頭之清潔片的清潔動作示意圖。依照本新 型一實施方式之清潔片100於清潔使用時，係仿一般光碟 6 M396603 片的使用法一樣，將清潔片100以其中心安裝孔113安裝承 載於光碟機之轉盤的轉轴（未圖示）上，此時清潔片100會 隨著轉盤而旋轉，而光碟機的光學拾訊頭200則朝向清潔 片100的徑向移動，在清潔片100旋轉及光學拾訊頭200徑 向移動的過程中，清潔片100所植設的刷體束130乃與光學 拾訊頭200接觸而予清潔。 然而如第6圖所示，依照本新型一實施方式之清潔片 100,當刷體束130以其端部132接觸到光學拾訊頭200時， 即光學拾訊頭200通過刷體束130時，刷體束130會以第一 面111之嵌固細孔121的内緣為支點123而彎曲，並進入作 為活動區的同心擴孔122。由於此時支點123距離光學拾訊 頭200較遠，因此相對於光學拾訊頭200而言，刷體束130 的支點變遠同時彎曲的刷體束的阻力減少，因而減少刷體 束130對於光學拾訊頭200的擦拭阻力及擦拭損傷；而且清 潔片100的平面偏移量變小，錯誤訊號減少，而能正常讀 取及正常清潔，可確實且輕易地清潔光碟機的光學拾訊 頭。 片體110所設之刷體束130可為多數例如三個刷體 束，在刷體束130為多數的情況下，該些刷體束130係間隔 設置，而且各個刷體束130至中心安裝孔113各為不同的半 徑距離，用以在清潔光學拾訊頭200時，各個刷體束130 可分別接觸到光學拾訊頭200的不同部位，使其清潔更為 完備。 第7圖是繪示依照本新型一實施式之光碟機光學拾訊 7 M396603 頭之清潔片之主要部份的剖視放大圖，並顯示其中的同心 擴孔122為一圓形的同心擴孔；第8圖是繪示第7圖所清潔 片的清潔動作示意圖。該第7圖及第8所示的清潔片結構具 有與第5圖及第6圖所示之清潔片相同的使用功效。 依據本新型光碟機籴學拾訊頭之清潔片，可依其二階 孔部的設計，大幅減少刷體束清潔時產生的阻力，減低對 光學拾訊頭的擦拭傷害，並可避免清潔片的誤動作，且可 確實且輕易地清潔光碟機的光學拾訊頭。以上所述，確實 達到本新型之創作目的。 本新型雖已藉由上述較佳實施例加以詳細說明，惟以 上所述者，僅為本新型之較佳實施例而已，當不能以此限 定本新型實施之範圍，即大凡依本新型申請專利範圍及新 型說明内容所作簡單的等效變化與修飾，皆仍屬本新型專 利涵蓋之範圍内。 【圖式簡單說明】 為讓本新型之上述和其他目的、特徵、優點與實施例 能更明確易懂，所附圖式之說明如下： 第1圖是繪示一種習知光學拾訊頭清潔片的剖視圖。 第2圖是繪示第1圖所示清潔片的清潔動作示意圖。 第3圖是繪示依照本新型一實施式之光碟機光學拾訊 頭之清潔片的仰視圖。 第4圖是繪示第3圖所示清潔片的剖視圖。 第5圖是繪示第4圖所示清潔片之主要部份的剖視放 8 M396603 大圖，並顯示其中的同心擴孔為一錐形的同心擴孔。 第6圖是繪示第5圖所清潔片的清潔動作示意圖。 第7圖是繪示依照本新型一實施式之光碟機光學拾訊 頭之清潔片之主要部份的剖視放大圖，並顯示其中的同心 擴孔為一圓形的同心擴孔。 第8圖是繪示第7圖所清潔片的清潔動作示意圖。 【主要元件符號說明】 110 :片體 112 :第二面 120 :二階孔部 122 :同心擴孔 130 :刷體束 132 :端部 • 100 :清潔片 111 :第一面 113 :中心安裝孔 121 :嵌固細孔 123 :支點 131 :根部 200 :光學拾訊頭M396603 V. New description: [New technical field] The present invention relates to a cleaning sheet, in particular to a cleaning sheet for an optical pickup of an optical disc drive. [Prior Art] When the CD player (BD/DVD/CDPlayer) is stored or used, it may infiltrate dust or other foreign matter, contaminating its optical pickup, resulting in a bad read signal or unsuccessful purchase. The optical pickup is cleaned with a cleaner. A general optical pickup cleaner is a device in which a brush body is implanted on a sheet like a disc, and the optical pickup is cleaned by the brush body when the optical pickup passes through the brush body. 1 and 2 are a cross-sectional view and a cleaning operation diagram of a conventional optical pickup cleaning sheet. As shown, the conventional optical pickup cleaning blade φ 300 stores a signal similar to that of a general optical disk, and is fixed perpendicularly through the first side 311 to the opposite second surface 312 of the body 31. The hole 313' is used to implant a brush bundle 320; that is, the brush bundle 320 is implanted and fixed to the entire thickness of the wafer 310, and protrudes toward the second surface 312. When the optical pickup 200 of the optical disk drive passes through the brush bundle 320, the end of the brush bundle 320 contacts the optical pickup 200, and is bent by the inner edge of the fixing hole 313 of the second surface 312 as a fulcrum 314. fold. However, the fulcrum 314 is very close to the optical pickup 200', that is, the fulcrum 314 is shorter than the optical pickup 200, so that the brush bundle 320 is bent by the fulcrum 314 and contacts the optical pickup 200 to generate 3 M396603. Larger resistance, and this excessive contact resistance can cause damage to the optical pickup 200; especially for short-wavelength Blu-ray pickups (BD Laser Lens), the distance between the pickup and the disc is more Therefore, the resistance generated by the brush bundle 320 after being bent by the fulcrum 314 is greater, so that the damage to the pickup 200 is more obvious; and the excessive contact resistance also causes the offset of the cleaning sheet 300, resulting in The optical disk drive cannot read the signal or the disconnection of the cleaning chip 300, which causes the cleaning action to be poor or impossible to clean. • Due to the above reasons, the application of the conventional optical pickup cleaning sheet is not good. [New Content] The purpose of the present invention is to provide a cleaning sheet for an optical pickup of an optical disc drive, which can greatly reduce the resistance generated during cleaning, and can reliably and easily clean the optical pickup of the optical disc drive.

The sheet body has a first surface and a second surface opposite to each other; the sheet body is provided with at least one brush body bundle with at least one second-order hole portion; wherein the second-order hole portion includes a matching hole and a connecting hole Concentric reaming, the intervening pores are disposed on the first side of the sheet body, and the concentric reaming holes are formed on the second side of the sheet body; the brush body bundle is formed by a plurality of brush bodies, and the brush body bundle includes an opposite portion and One end portion, the root portion is embedded in the fixing hole, and the end of the M396603 protrudes toward the second surface of the sheet body through the concentric reaming hole. When the brush body beam cleans the optical pickup head, the brush body bundle is bent with the inner edge of the first surface of the embedded fine hole as a fulcrum, and enters a concentric reaming hole as an active area; the fulcrum of the brush body bundle becomes far away and bends The resistance of the brush body beam is reduced, the wiping resistance and wiping damage of the brush body bundle to the optical pickup head are reduced; and the plane offset of the cleaning sheet is reduced, the error signal is reduced, and the normal reading and normal cleaning are possible. According to an embodiment of the invention, the concentric reaming is a conical or circular 'concentric reaming such that the brush body region has a larger active area. According to an embodiment of the present invention, the body of the brush body is provided in a plurality of spaces and spaced apart, and each of the brush body bundles has a different radial distance from the center mounting hole, and can be separately contacted according to the cleaning. Different parts of the optical pickup make it more complete. According to an embodiment of the present invention, the first surface is a signal surface of the cleaning sheet, and a printing surface is coated thereon, and the second surface is a reading surface of the cleaning sheet for reading the signal of the clearing sheet by the second surface. . The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figures 3 through 5, respectively, a bottom view, a cross-sectional view, and a cross-sectional enlarged view of a main portion of a cleaning sheet of an optical pickup of an optical disk drive according to an embodiment of the present invention are shown. As shown in the figure, the cleaning sheet 100' of the optical pickup 5 M396603 of the optical disc drive according to the embodiment of the present invention has a sheet 110 of the same size as a general optical disc and storing a signal, and the wafer 110 has a central mounting. The hole 113 is used for a woman's disc on a disc drive (not shown); and the sheet H0 has a first surface 111 and a second surface 112. In practice, the first surface U1 The signal surface of the cleaning sheet loo is covered with a printing surface, and the second surface 112 is a reading surface of the cleaning sheet 100 for reading the signal stored on the signal surface. The cleaning sheet 100 according to an embodiment of the present invention is designed so that the sheet body 110 is provided with at least one second-order hole portion 120 (the embodiment of the drawing shows two second-order holes). Brush bundle 13 0 (the embodiment of the drawing shows three brush bundles). Wherein, the second-order hole portion i 2 〇 includes a concentric hole 丨 21 connected to the hole and a concentric reaming hole 122 having a concentric center with the hole, for example, a concentric concentric hole; the embedded hole 121 is disposed on the piece u The first side 111 of the crucible, and the concentric reaming 122 are formed on the second side 112 of the sheet 11 (), so that the aperture of the concentric reaming 122 on the second surface 112 is significantly larger than the embedding φ. The aperture of 111. The brush bundle 130 is assembled from a plurality of brush bodies. The brush body bundle 13 includes an opposite portion 131 and an end portion 132. The root portion 131 is fixed to the second end hole portion 120. The end portion 13 2 of the insertion hole 121' is concentrically reamed through the second-order hole portion 12 122 protrudes toward the second face ip of the sheet body 110. The concentric reaming 122 forms an active area that allows the brush bundle 130 to move therebetween. Please refer to FIG. 6 , which is a schematic diagram showing the cleaning operation of the cleaning sheet of the optical pickup of the optical disc drive according to an embodiment of the present invention.
