”員示器12。顯示器12可係以一軸承14樞接機體1 〇， 於一預定角度内掀闔於機體1〇之上表面。 盤6及觸控面板18係用以輸入資料，設置於機 ㈣之上表面。各式電财件皆可安裝於機體心顯示器 2可包括一顯示螢幕19用以顯示各種資訊。 開放式插槽（未顯於圖示）開設於機體1〇之一侧… ==裳置2〇可插設於其中。前述可插設之擴充裝置 、、也i ’㈣：同之裝置’例如一光碟機、一插槽式備用電 池或一發射單元。 20 J312920 在本發明之實施例中，一數位廣播發射-接收機可為前 述之擴充裝置20’其可接插設或配備於擴充裝置内。請參 閱圖2所示之本發明之一實施例。 如圖2所示’ 一殼體3〇界定一發射-接收機之輪廓。於 5圖2中，移除殼體30之上表板用以顯示殼體30内之内部構 造。殼體30實質上可為一具有一預設之内室32之六面體， 亦可依機體10之插槽作形狀上之改變，而具有似光碟機等 • 同結構之殼體3〇也可應用於如圖2所示之實施例。 殼體30之内室32可包括一主基板34。主基板34可裝設 10各式用以傳送及接受數位廣播訊號之元件，主基板34較佳 • 之元件為通訊晶片，如數位廣播晶片或其他相關元件。為 方便起見，該等元件並未顯示於圖示中。主基板34可安裝 於设體30之内至32中靠較後端之處。由於殼體％之内室μ 中較主基板34大，主基板34盡可能裝設於對應一用以電性 15 連結一接收器與一主機板之連接器36之處。 主基板34與連接器36組設為較佳。接收器經由連接器 * 36可電連結至安裝於機體1〇或是主機板上之元件。連接器 36可谷设於殼體30之内室32中，或凸出於殼體3〇外，其結 構將依主機板之設計而作調整。如圖2所示，本實施例中， 20惟連接器36之前表面曝露於殼體3〇外，連接器36位於殼體 30之内室32中’然本發明並非受限於此。 一天線基板40可安裝於内室32，得以經由一傳輸線％ 電連結至主基板34。儘管天線基板4〇可與主基板34整合為 一，但合併上述基板後，將使面積變得較大，故在本實施 1312920 例中’將主基板34與天線基板40分離為二，俾可降低或縮 減面積至最小。另外，若將主基板34與天線基板40分別製 ^ ’可降低或清除主基板34與天線基板4〇或裝設於其裝置 等το件所可能產生之雜訊干擾，進而提升其電性穩定度。 5或者利用（如加強）接地與屏蔽等技術來降低或解決前述雜訊 干擾。 天線基板4〇可固設一過濾晶片42，過濾晶片42可用以 消除由一天線50所接收訊號中之雜訊。過濾晶片42可經由 傳輸線38得到所需之電力。 10 天'線50可安骏於上述之天線基板40。例如，天線基板 40可包括一固定件51，固定件51可具有一軸櫬部（Bushing portion)52(如一圓柱形轴櫬部）。軸櫬部52可設有一接頭53 穿設一通孔5 3 ’。接頭5 3可電性連接至設於天線基板上之一 電路佈局。接頭53可供一天線主體54旋轉及線形伸收等動 15 作’並同時提供天線主體54及天線基板40間之通聯。 天線主體54可包括一支樓部55(Support portion)、一連 接部60(Connection portion)及一前端 62(Head portion)。支 撐部55、連接部60及前端62可為一桿體並可以金屬或類似 材質製成。支撐部55及連接部60亦可為一以具導電材質製 20 成之中空管體’俾用以傳輸及接收無線電電波° 支撐部55之外徑基本上可等於接頭53之通孔53’之内 徑，支撐部55俾可電性連接至接頭53並套設至接頭53之通 孔53,時可作旋轉及線形（如直線）等動作。支撐部55之一端 •5]*設有一凸緣56(Catching flange)。凸緣56之外徑係大於支 1312920 « 樓部55之其他部分之外徑為較佳，使支撐部55無法與接頭 53套脫。支撐部55之長度可設計成支撐部“之末端可貫穿 一開設於殼體30之前表面之一通孔至機殼外部（圖未示）， 例如’當凸緣56鉤設於接頭53時，一表面則曝露於機體⑺ 5 外。 支撐部55及連接部6〇可組設一接合部58(Anicuiati⑽ portion)於其中，接合部58可設計成提供連接部卯與支撐部 φ 55間作多角度之扳折’但本發明並非僅限於此。例如，接 合部58可設計為連接部60與支撐部55相互接合於一固定方 1〇向。又’接合部58亦可設計成以藉由一鉸栓（Articulation ， pm)(圖未示）使連接部6〇與支撐部55相互接合。 . 仏苢上述之連接部60之長度已預設，但仍可隨實際情 況而作改變，亦即若如圖2中連接部60係為一中空管體，連 $部60之長度則無法更改。但若連接部60係包括多個中空 15 g體’且該等官體之外徑趨增並相互伸縮連接，則連接部 60之長度就可調整，但本發明並非僅限於此。 連接部60之外徑可與支撐部55之外徑相同。因此，當 天線主體54完全收藏於殼體3〇内時，天線主體54可通過接 頭53之通孔53,。 月J鈿62可裝攻於連接部6〇之一末端。前端直徑可較 大刖知62可女裝一個或多個增強收訊之裝置。前端62之 卜仫可大於開没於殼體3〇之通孔之内徑，藉此無法將天線 主體54完全收藏於殼體3〇内之内室32。但本發明並非僅限 於此。刖端62可以不同之長度突出於殼體3〇外。 11 J312920 前端62可設有·—^合段64(Catching step)。卡合段64 外徑較小於前端62之外徑、藉此前端62得以卡合於殼體3〇 之通孔。 圖5及圖6係本發明用於攜帶式電腦之發射-接收機之 5 第二實施例。如圖5及圖6所示，所有元件符號係由第一實 施例中各別增加100作以區別，而其詳細敘述在此省略，但 第二實施例與第一實施例之差異處將另作描述。 如圖5及圖6所示之本實施例中，一主基板丨34及一天線 基板140可分別裝設於一殼體130之一内室132，一固定件 10 140可裝设於天線基板140上。一天線丨50可裝設並穿過固定 件151 ,而一天線150之連接部160及一前端162可突出於殼 體 130。 在本實施例中，一天線150之支撐部155可設有一壓合 •^又 155 (Press fitting step)鄰接於一凸緣 156。壓合段 155,之 15外徑可等於或約略大於一接頭153之一通孔153,之内徑。壓 合段155’之直徑可大於支撐部155其他部位之直徑。藉此避 免壓合段155’因不慎而懸卡於固定件Hi。 由於一前端162之卡合段164外徑可等於上述壓合段 155’之外徑，當天線150之連接部16〇完全收藏於殼體13〇内 20而一天線主體154無法拉出殼體30之外時，卡合段164可壓 合至接頭153之通孔153’。在本實施例中，藉由固定件151 固設之天線基板140可鄰接殼體13〇之一側壁，藉此該固定 件151則可鄰接開設於殼體13〇之前表面之通孔。 一擋片170(Support)可凸設於一殼體13〇之内室132底 12 1312920 面上。一嵌塊172(Insertion rib)可形成在檔片170的表面 上。一導管l74(Guide duct)—端可環接在嵌塊172，該嵌塊 Π2可將導管174—端固定於擋片170。導管174可用以導正 天線主體154之連接部160及支撐部155之作動，並導正天線 5 主體154安裝於内室132中之位置。導管174另一端可插設於 固定件151 ’該導管Π4之内徑寬度以足夠提供天線主體154 於其中作動及收藏為較佳。 圖7及圖8係本發明用於攜帶式電腦之發射-接收機之 第三實施例。如圖中所示，所有元件符號係由第—實施例 10 中對應符號各別增加200，以作區別。 如圖7所示，一發射-接收機之外型可由一殼體230所界 定’但為了顯示殼體230之内部構造，故將殼體230之頂面 攸圖中移除。殼體230可係為一平面（如六面形）構成一預設 之内室232。殼體230也可依機體1〇之插槽之形狀所構成。 15 如一光碟機結構之殼體230亦可應用於本第三實施例，但本 發明並不限於此。 殼體230之内室232可固設一主基板234。主基板234可 固設有各式用以接收及傳送數位廣播訊號之零組件。主基 板234可固設通訊晶片例如數位廣播晶片或其他相關零組 20 件。在第三實施例中’為方便起見，該等零組件並未標示 元件符號。 主基板234可安裝於殻體230之内室232中較後端位 置。因设體230之内室232比主基板2 3 4較寬大，故為了電性 連接主機板與接收機，主基板234盡可能對應裝設於連接器 13 1312920 器236之處。 主基板234可以螺絲釘234,固設於殼體230。例如主基 板234可以嫘絲釘234,固定凸設於殼體230底面之凸座（圖 未示），藉以將主基板234固設於殼體23〇。 5 一可凸設於殼體230外之連接器器236可裝設於後壁之 外表面。連接器236係以電性連接發射-接收機至固設於機 體10或主機板上之元件。連接器236可固設於一連接器基板 237(Connector substrate)上。連接器基板237可裝設（如平行 裝設）於設有連接器236之後側内壁上。連接器基板237與主 10 基板234玎經由連結器237’相互電性連結。連結器237,可分 別固設於連接器基板237與主基板234上，俾用以相互電性 連接上述二元件。 一天線基板240可安裝於内室232，得以經由一傳輸線 238電性連結至主基板234。天線基板240亦可以螺絲釘240, 15 固設於殼體230上。儘管天線基板240可與主基板234整合為 一，但合併上述基板後，將使面積變得較大，故在本第三 實施例中，將主基板234與天線基板240分離為二，俾可降 低或縮減面積至最小。另外，若將主基板234與天線基板240 分別製造’可降低或清除主基板234與天線基板240或裝設 20 於其裝置等零組件所可能產生之雜訊干擾，進而提升其穩 定度。或者利用（如加強）接地與屏蔽等技術來降低或解決前 述雜訊干擾。 天線基板240可包含一過濾晶片。過濾晶#可用以消 除由一天線250所接收訊號中之雜訊。在此例子中，利用— 14 1312920 具有多排之排線或一較具可撓之傳輸線作為傳輸線238較 佳。 天線基板240可安裝鄰接於殼體230之前表面之處，而 天線250則可安裝鄰接於天線基板240之處。一固定件251 5 可固設於殼體230之底面並鄰接天線基板240。固定件251 可電性連接至天線基板240。 固定件25 1可具有一預設外形的軸櫬部252。軸櫬部 252可設有一接頭253穿設一通孔253 ’。接頭253可電性連接 至設於天線基板240上之一佈局電路。接頭253可供一天線 10 主體254旋轉及直線伸收等動作。接頭253並同時提供天線 主體254及天線基板240間之通聯。 天線主體254可包括一支撐部255、一連接部260及一 前端262。支撐部255、連接部260及前端262可為一桿體並 可由金屬製成。支撐部255及連接部260亦可為一中空金屬 15 管。 支撐部255—端可設有一壓合段255’。由於壓合段255’ 之直徑大於天線主體254其他部位之直徑，壓合段255’故得 壓合於通孔253’。因此除壓合段255’外，天線主體254其他 部位之外徑皆可小於通孔253’之内徑，進而使天線主體254 20 作最順暢之直線作動（如往復作動等）。若天線主體254之構 成為以上所述，則可降低天線之整體重量及大小。 壓合段255’可配予一可精確壓合於接頭253之通孔 253’内徑大小之外徑。由於壓合段255’之外徑及通孔253’ 之内徑與無線電波之傳送及接受速率有極大的關係，因此 15 1312920 尺寸之製造公差能降至最小為較佳。支撐部255則可電性連 接至接頭253，並可旋轉及直線作動於接頭253之通孔253’ 中。但壓合段255’可壓合於接頭253之通孔253’，故無法刻 意地將壓合段255’轉動，但若施用一外力超過一個預設值 5 時，壓合段255’則可旋轉或直線作動。 支撐部255—端可設有一凸緣256。凸緣256之外徑係 大於支撐部255之其他部分之外徑為較佳，俾使支撐部255 無法與接頭253套脫。支撐部255之長度可設計為，當凸緣 256鉤設於接頭53時，支撐部255之末端可貫穿一開設於殼 10 體230之前表面之一通孔並凸伸至機殼外。 支撐部255及連接部260之間可組設一接合部258於其 中，接合部258可供連接部260對支撐部255作多角度之扳 折。但本發明並不限於此。例如，接合部258可供連接部260 與支撐部255於一固定方向相互卡合。又，接合部258亦可 15 藉由一鉸栓（圖未示）將連接部260與支撐部255相互卡合。 連接部260有一預設長度且可包括多個中空管體且該 等管體之外徑長度趨增並相互伸縮連接。因此連接部260 之長度可變動。連接部260之最大外徑約略小於通孔253’ 之内徑為較佳，俾使天線250較容易伸縮於殼體230内外。 20 前端262可裝設於連接部260之一末端。前端262直徑 可較大。前端262可另外安裝一增強收訊之裝置。此外，前 端262可以不同之長度突出於殼體230外。 前端262可設有一卡合段264，其外徑較大於開設於殼 體230前表面之通孔。因此天線主體254即無法完全收藏於 16 1312920 殼體230之内室232。一壓合段265可鄰設於卡合段264。壓 合段265之外徑等於接頭253之通孔253’之内徑為較佳。例 如，由於壓合段265之外徑等於壓合段255’之外徑，當天線 250收藏於殼體230時，天線250得以固定於固定件251。據 5 此，天線250則無法伸出殼體230外。 一檔片270可凸設於一殼體230之内室232之底面上。擋 片270之一表面可設有一嵌塊272。一導管274—端可對應環 接嵌塊272。該嵌塊272可將導管274之一端固定於擋片270。 導管274可用以導正天線主體254之連接部260及支撐 10 部255之作動，並導正天線主體254安裝於内室232中之位 置。導管274另一端可插設於固定件251，該導管274之内徑 寬度以足夠提供天線主體254於導管274中作動及收藏為較 佳。 圖10係本發明用於攜帶式電腦之發射-接收機之第四 15 實施例分解透視圖。圖11係本發明第四實施例中天線及導 管之分解透視圖。 如圖10及圖11所示，一發射-接收機之外型可由一殼體 330所界定。為了顯示殼體230之内部構造，故於圖10中將 殼體330之頂面從圖中移除。殼體330係為一平面（如六面形） 20 構成一預設之内室332。殼體330也可依機體10之插槽形狀 而不同。如一光碟機之外殼亦可應用於本第四實施例。 殼體330之内室332可固設一基板334。基板334可固設 有各式用以接收及傳送數位廣播訊號之零組件。例如基板 334可固設通訊晶片，如數位廣播晶片或其他相關零組件。 17 1312920 在本第四實施例中，為方便起見，該等零組件並未標示元 件符號。 基板334可安裝於殼體330内室332中鄰接前表面之位 置（如當殼體330插設於機體10插槽時機體之一面顯露在 5 外）。基板334—側邊無須接觸至前表面。基板334可安裝鄰 接於前表面之用意在於降低或使安裝於機體10之主機板之 干擾減至最小。 I 基板334可以螺絲釘334’固設於殼體330。例如，基板 334可以螺絲釘334’固定凸設於殼體330底面之凸座（圖未 10 示），藉以將基板334固設於殼體330。 一可凸設於殼體330外之連接器336可裝設後壁之外表 面。連接器336係以電性連接發射·接收機至固設於機體10 ' 或主機板上之零組件。連接器336可固設於一連接器基板 337上。連接器基板337可安裝於殼體330(如設有連接器336 15 之後壁内側上）。連接器基板337與基板334可經由一可撓傳 輸線338或類似傳輸線相互連結。 • 基板334不但可固設有上述數位廣播相關之晶片，也 可固設有天線350相關之零組件。但本發明並不僅限於此。 由於基板334固設有多個零組件，可能產生零組件之間雜訊 20 干擾。但可利用接地與屏蔽等技術來有效降低甚至解決前述 雜訊干擾問題。 天線350可安裝於殼體330之一側鄰接基板334。於該 側，一固定件351可固設於殼體330之底面並鄰接基板334。 固定件351與基板334可相互傳輸訊號。 18 1312920 固疋件35丨可包括一既有形狀之軸櫬部352。其嗖有一 接頭353穿設-通孔353、接頭353可電性連接至設於基板 334上之-佈局電路。接頭353可支托—天線主體354並同時 提供天線主體354及基板334間之通聯。 5 10 15 20 天線主體354可包括一支撐部355、_ 前= 362。但本發明並不限於此。支撐部355、連接部36〇 及别鈿362可為一桿體並可由金屬或類似材質所製成。支撐 部355及連接部360亦可為一以具導電材質製成之中空管 體’用以收發無線電波。 支撐部355—端可設有一壓合段355、由於壓合段355, 之直徑大於天線主體354其他部位之直徑，壓合段355，故得 壓合於通孔353’。因此除壓合段355,外，天線主體354其他 部位之外徑皆可小於等於通孔353,之内徑，進而使天線主 體354作最順暢之作動（如直線作動等）c>若天線主體354之構 成為以上所述’則可降低天線之整體重量及大小。 壓合段355,可配予一可精確壓合於通孔353,内徑大小 之外徑。由於壓合段355’之外徑及通孔253,之内徑與無線電 波之傳送及接受速率有極大的關係，因此尺寸之製造公差 月包降至最小為較佳。支撐部355則可電性連接至接頭353， 並可至少於接頭353之通孔353，中作旋轉及直線等動作。然 而’壓合段355,壓合於接頭353之通孔353,為較佳，因此壓 合段355’無法轉動，但若施用一超過預設值之外力時，壓 合段355’則可旋轉或直線作動。 支撐部355—端可設有一凸緣356。凸緣356之外徑可 19 1312920 大於支撐部355其他部分之外徑，俾使支撐部355無法與接 頭353套脫。支撐部355之長度可設計為，當凸緣356拉近至 接頭353時，支撐部355之末端可貫穿一開設於殼體330之前 表面之一通孔並凸伸至機殼外。 5 支撐部355及連接部360之間可組設一接合部358於其 中。接合部358可供連接部360對支撐部35 5作選擇性地作動 (如多角度之扳折等）。接合部358亦可供連接部360對支撐 部355作一定角度之扳折。例如，接合部358可藉由一鉸栓 (圖未示）將連接部360與支撐部355相互卡合。但本發明並 10 不僅限於此。 連接部360可設有一既定長度且包括多個中空管體， 該等管體之外徑長度趨增並相互伸縮連接。因此連接部360 之長度可變動。連接部360之最大外徑約略小於通孔353’ 之内徑為較佳，俾使天線350較容易伸縮於殼體230内外。 15 前端362可設在連接部360之末端。前端360可有一較 大之直徑。在前端362可設附加的結構（例如零件或其類似 物）以增加接收速率。突出於機殼330的前端362可有多樣的 設計。 前端362可設有一卡合段364，卡合段364外徑可較開 20 設於殼體330前表面之通孔的内徑大，因此天線主體254即 無法完全收藏於殼體330之内室332。一壓合段365可鄰設於 卡合段364。壓合段365之外徑可相當於接頭353之通孔353’ 之内徑。例如，由於壓合段365之外徑等於壓合段355’之外 徑，當天線350收藏於殼體330時，天線350得以固定於固定 20 1312920 件35 1。據此，天線350則無法因不慎或在無前述外力施用 時凸伸於殼體330外。 一擋片370可凸設於一殼體330之内室332底面上。擋片 370之一表面可設有一嵌塊372。一導管374—端可對應環接 5 嵌塊372。該嵌塊372可將導管374 —端固定於擋片370。然 而，也可應用其他結構以固定及支撐導管374。導管374可 供支承天線主體354之支撐部355，亦可避免天線主體354過 於深陷於殼體330内。 導管374可用以導正天線主體354之連接部360及支撐 10 部355之作動，並導正天線主體354安裝於内室332中之位 置。導管374另一端可插設於固定件351。該導管274之内徑 寬度以足夠提供天線主體354於其中作動及收藏即可。 然而，天線主體354並不須包括一前端362。例如，就 只有連接部360而無前端362而言，且天線主體354完全插入 15 於殼體330内，連接部360則可設計一長度凸伸（於所需之長 度）於殼體330前表面之外。換言之，天線350即可伸展於殼 體330内。 ’ 本發明實施例中一種用於攜帶式電腦之數位廣播發射 -接收機之使用操作將在此說明。實施例中數位廣播發射-20 接收機之使用方法將在此藉由圖2至12(b)詳細說明，然本發 明並非僅限於此。 使用本發明實施例之發射-接收機時，可選擇性地插設 於一開設於一攜帶式電腦機體之插槽中。例如，發射-接收 機可係一擴充裝置，如一光碟機、一插槽式備用電池或一 21 .1312920 發射單元等類似插入式裝置。 田使用者欲利用攜帶式電腦觀看數位轉播時，使用者 可將本發明實施例之發射-接收機插入機體10之插槽。若將 發射-接收機插設於機體10之插槽，連接器36可電性連接至 5主機板（於機體10中）’俾將所需電力及訊號傳送至主基板 (主基板34)。 使用者可將天線主體54由殼體3〇拉出以增強其收訊。 φ 如圖2中使用狀態所示，天線主體54之前端62可用手拉出。 若將前端62拉出，天線主體54之支撐部兄及連接部⑹亦同 1〇時被拉出殼體30外。又如圖2使用狀態所示，天線可直線作 動，使連接部60穿過開設於軸櫬部52之接頭53之通孔53,。 連接部60穿過接頭53後，支撐部55可接續穿過接頭兄之通 孔53,。 天線主體54由殼體30拉出至支撐部55之凸緣％與接頭 15 53卡合為止。圖4a係天線主體54由殼體30拉出之使用狀 態。在此時，僅有支撐部55之末端可凸伸至殼體3〇之外， 馨 連接部60則已完全伸出殼體3〇外，然而本發明並非侷限於 此。 另外，連接部60可經由與接合部68之枢接進而連接至 2〇支撐部55，藉此，使用者可調整天線以搜尋最佳之收訊方 位。若將連接部60於接合部68扳折，支撐部55則可於接頭 53之通孔53’内作旋轉。圖扑係顯示該使用狀態。 當連接部60或其類似物之長度可調整時，則可依據最 佳之收訊方位，藉由調整連接部60之長度，以設定天線主 22 1312920 體54位置。支撐部55或前端62之長度亦可調整。 由天線主體54所收發之廣播訊號可經由天線主體54 达至接頭53，再傳輸至固設於天線基板40之過濾晶片42。 訊號中之雜訊經過濾晶片42移除後，經由傳輸線％傳輸至 5主基板34。之後，訊號再經由連接器36傳輸至主基板之晶 片，主機板將訊號轉化為影像播放於顯示器12之螢幕Μ 上，聲音則透過揚聲器播放。如此，使用者即可觀看到轉 播。 圖5及圖6係本發明第二實施例，其中天線主體154可 1〇延殼體130内之導管174作動。因此天線主體154可更精確地 於殼體130内移動，俾能降低天線主體154損壞之機率。 在天線主體154凸伸出殼體130外之狀態時，壓合段 155’可壓合於固定件151之通孔153,，使天線主體154無法 因不慎而移動或懸卡於殼體内。換言之，天線主體154可保 15持伸出殼體130外之狀態。凸緣156可卡合於固定件151，使 天線主體154無法再向殼體3〇外延伸。 如圖9a至9c所示，第三實施例之發射_接收機之使用操 作將在此說明。若本實施例之發射-接收機插設於機體1〇之 插槽’連接器236則可電性連接至主機板。 2〇 使用者可將天線主體254由殼體23〇拉出以增強其收 訊。如圖7中使用狀態所示，天線主體254之前端262可用手 拉出。若將前端262拉出’天線主體254之支撐部255及連接 部260則同時被拉出殼體23〇。又如圖7中狀態所示，天線可 直線作動，使連接部26〇直線穿過開設於軸櫬部252之接頭 23 1312920 253之通孔253’。當連接部260穿過接頭253時，支撐部255 可接續直線貫穿接頭253之通孔253’。 天線主體254由殼體230拉出直到支撐部255之凸緣256 與接頭25 3卡合為止。圖9a係天線主體254由殼體230拉出之 5 使用狀態，如圖9a所示只有支撐部255之末端可凸伸至殼體 230之外為較佳。此時連接部260則已完全伸出殼體230外。 因此，支撐部255之壓合段255’可壓合於接頭253之通 孔253 ’，使天線主體254無法因不慎而移動。舉例而言，唯 有當一超出一預設值之外力施用於天線主體254時，天線主 10 體254方可對於固定件251產生作動。 接著，為了使用者可調整天線以搜尋最佳之收訊方 位，連接部260可對支撐部255作動（藉由與接合部258之樞 接）。若將連接部260於接合部258之樞接處扳折，支撐部255 則可於接頭253之通孔253’内作旋轉。圖9b係顯示該使用狀 15 態，然而其中更可包含多個接合部。 本發明第三實施例中，連接部260之長度可調整。因 此，如圖9c所示，可依據最佳之收訊方位，藉由調整連接 部260之長度，以設定天線主體254位置。 另外，當不使用天線250時，天線主體254可收入殼體 20 230内。例如，當使用者將天線主體254推入殼體230内時， 天線主體254可移動並被導正於導管274之管體中。天線主 體254持續推進直到支撐部255以擋片270支承為止。 擋片270係阻擋天線主體254推入超出其預設長度。當 天線主體254以其連接部260完全收入時之長度推入殼體 24 1312920 230内時，壓合段265可壓合於固定件251之通孔253’。此係 為固定件251固設鄰接於殼體230前表面及壓合段265設有 一既定長度之原因。因此即便殼體230向下傾斜時，天線250 無法掉落出殼體230外。就一般情況而言，即使當天線主體 5 254收藏於殼體230内時，前端262仍可曝露於殼體230外， 然而本發明並非僅限於此。 如圖12a及圖12b所示，第四實施例之發射-接收機之使 用操作將在此說明。若本實施例之發射-接收機插設於主體 10之插槽，連接器336則可電性連接至主機板。 10 又，使用者可將天線主體354由殼體330拉取以增強其 收訊。如圖10中使用狀態所示，天線主體354之前端362可 用手拉出。若將前端362拉出，天線主體354之支撐部355及 連接部360則同時被拉出殼體330。又如圖10中狀態所示， 連接部360貫穿開設於軸櫬部352之接頭353之通孔353’。當 15 連接部360穿過接頭353時，支撐部355可接續直線貫穿接頭 353之通孔353’。 天線主體354由殼體330拉出直到支撐部355之凸緣356 與接頭353卡合為止。圖12a係天線主體354由殼體330拉出 之使用狀態。此時僅有支撐部355之末端可凸伸至殼體330 20 之外，而連接部360則已完全伸出殼體330外。 支撐部355之壓合段355’可壓合於接頭353之通孔 353’，使天線主體354無法因不慎而移動。舉例而言，唯有 當一超出一預設值之外力施用於天線主體354時，天線主體 354方可對於固定件351產生作動。 25 1312920 而為了使用者可調整天線以搜尋最佳之收訊方位，連 接部360可對支撐部355作動（藉由與接合部358之枢接）。若 將連接部360於接合部358之柩接處扳折，支撐部355則可於 接頭353之通孔353’内作旋轉。圖12b係顯示該使用狀態接 5 合部。 連接部360之長度可加以調整。因此，使用者可藉由調 整連接部3 6 0之長度移動前端3 6 2而有最佳之收訊位置。 當不使用天線350時，天線主體354可收入殼體230 内。例如，當使用者將天線主體354推入殼體330内時，天 10 線主體354可移動並被導正於導管374之管體中。天線主體 354持續推進直到支撐部355以擋片370支承為止。 擋片370係阻擋天線主體354推入殼體330既定長度。 當天線主體354以其連接部360完全收入時之長度推入殼體 330内時，壓合段365可壓合於固定件351之通孔353’。此係 15 為固定件351得固設鄰接於殼體330前表面及壓合段365設 有一既定長度之原因。在此狀態下，即便殼體330向下傾斜 時，天線350不會掉落出殼體330外。而即使當天線主體354 收藏於殼體330内時，前端362仍可曝露於殼體330外。依據 本發明實施例中一種用於攜帶式電腦用數位廣播發射-接 20 收機及其方法，數位廣播可用以一般傳統攜帶式電腦觀 看。由於使用者可依需要將發射-接收機插設於攜帶式電 腦，攜帶式電腦之擴充性也隨之提升。另外，由於實施例 之發射-接收機較於輕薄短小，其輕便性及訊號傳輸接收品 質皆相對提高。 26 1312920 藉由插設一天線於-插槽式擴充裝置，實施例之發射_ 接收機可提供一具有充极4ώ 、 長度之天線（如可伸縮天線主體） 以有效支援數位廣播服務。办Μ . 務例如，貫施例之發射-接收機可 支援數位廣播服務，如DMB或HDTV等服務。另外，本發明 之實施例亦可支援-種互動式數位廣播服務。 10 15 20 於本說明書中提及任何有關‘一種實施例，、‘ -實施例，

The filter wafer 42 can be supplied with the required power via the transmission line 38. The 10-day 'line 50 can be placed on the antenna substrate 40 described above. For example, the antenna substrate 40 may include a fixing member 51, and the fixing member 51 may have a bushing portion 52 (e.g., a cylindrical shaft portion). The shaft portion 52 can be provided with a joint 53 through a through hole 5 3 '. The connector 53 can be electrically connected to a circuit layout provided on the antenna substrate. The connector 53 can be rotated by an antenna body 54 and linearly extended to provide a communication between the antenna body 54 and the antenna substrate 40. The antenna body 54 may include a support portion 55, a connection portion 60, and a front portion 62. The support portion 55, the connecting portion 60 and the front end 62 may be a rod body and may be made of metal or the like. The support portion 55 and the connecting portion 60 may also be a hollow tube body 20 made of a conductive material for transmitting and receiving radio waves. The outer diameter of the support portion 55 may be substantially equal to the through hole 53' of the joint 53. The inner diameter of the support portion 55 is electrically connected to the joint 53 and is sleeved to the through hole 53 of the joint 53, and can be rotated and linear (such as a straight line). One end of the support portion 55 • 5] * is provided with a flange 56 (Catching flange). The outer diameter of the flange 56 is greater than the outer diameter of the portion 1312920 «the other portion of the floor portion 55 is preferred so that the support portion 55 cannot be detached from the joint 53. The length of the support portion 55 can be designed such that the end of the support portion can penetrate through a through hole formed in the front surface of the housing 30 to the outside of the casing (not shown), for example, when the flange 56 is hooked on the joint 53, one The surface is exposed to the outside of the body (7) 5. The support portion 55 and the connecting portion 6A can be provided with an engaging portion 58 (Anicuiati (10) portion), and the engaging portion 58 can be designed to provide a multi-angle between the connecting portion 卯 and the supporting portion φ 55 The invention is not limited thereto. For example, the joint portion 58 can be designed such that the joint portion 60 and the support portion 55 are joined to each other in a fixed direction. The joint portion 58 can also be designed to be A hinge (Articulation, pm) (not shown) engages the joint portion 6〇 with the support portion 55. The length of the connecting portion 60 is preset, but can still be changed according to the actual situation, that is, if the connecting portion 60 is a hollow tube as shown in FIG. 2, the length of the portion 60 cannot be changed. . However, if the connecting portion 60 includes a plurality of hollow 15 g bodies and the outer diameters of the main bodies are increased and connected to each other, the length of the connecting portion 60 can be adjusted, but the present invention is not limited thereto. The outer diameter of the connecting portion 60 may be the same as the outer diameter of the support portion 55. Therefore, when the antenna main body 54 is completely housed in the casing 3, the antenna main body 54 can pass through the through hole 53 of the joint 53. The month J钿62 can be mounted on one end of the connecting portion 6〇. The diameter of the front end can be larger than that of the one or more devices that enhance the reception. The front end 62 can be larger than the inner diameter of the through hole which is not opened in the casing 3, whereby the antenna main body 54 cannot be completely stored in the inner chamber 32 in the casing 3. However, the invention is not limited to this. The ends 62 can protrude beyond the casing 3 at different lengths. 11 J312920 The front end 62 can be provided with a 64 (Catching step). The engaging portion 64 has an outer diameter smaller than the outer diameter of the front end 62, whereby the front end 62 is engaged with the through hole of the housing 3''. 5 and 6 show a second embodiment of the present invention for a transmitter-receiver of a portable computer. As shown in FIG. 5 and FIG. 6, all component symbols are distinguished by increments of 100 in the first embodiment, and detailed descriptions thereof are omitted herein, but the difference between the second embodiment and the first embodiment will be different. For description. As shown in FIG. 5 and FIG. 6 , a main substrate 丨 34 and an antenna substrate 140 can be respectively disposed in an inner chamber 132 of a housing 130 , and a fixing member 10 140 can be mounted on the antenna substrate. 140 on. An antenna cymbal 50 can be mounted and passed through the fixture 151, and a connecting portion 160 of an antenna 150 and a front end 162 can protrude from the housing 130. In this embodiment, the support portion 155 of an antenna 150 may be provided with a press fitting step 156 adjacent to a flange 156. The outer diameter of the pressing section 155, 15 may be equal to or slightly larger than the inner diameter of the through hole 153 of one of the joints 153. The diameter of the pressing section 155' may be larger than the diameter of other portions of the support portion 155. Thereby, the pressing section 155' is prevented from being caught by the fixing member Hi due to carelessness. Since the outer diameter of the engaging portion 164 of the front end 162 can be equal to the outer diameter of the pressing portion 155', when the connecting portion 16 of the antenna 150 is completely stored in the housing 13, the antenna body 154 cannot be pulled out of the housing. When the outer portion is 30, the engaging portion 164 can be pressed to the through hole 153' of the joint 153. In this embodiment, the antenna substrate 140 fixed by the fixing member 151 can abut one side wall of the casing 13 , whereby the fixing member 151 can abut the through hole formed in the front surface of the casing 13 . A baffle 170 (Support) may be protruded from the bottom surface of the inner chamber 132 of the casing 13 12 12 1312920. An insert rib 172 can be formed on the surface of the flap 170. A conduit l74 can be looped onto the insert 172, which secures the conduit 174 end to the flap 170. The conduit 174 can be used to actuate the connection portion 160 of the antenna body 154 and the support portion 155, and to guide the position of the antenna 5 body 154 in the inner chamber 132. The other end of the conduit 174 can be inserted into the fixing member 151'. The inner diameter of the conduit 4 is sufficient to provide the antenna body 154 for actuation and storage therein. 7 and 8 are a third embodiment of a transmitter-receiver for a portable computer of the present invention. As shown in the figure, all the component symbols are incremented by 200 corresponding symbols in the first embodiment to distinguish them. As shown in Fig. 7, a transmitter-receiver profile can be defined by a housing 230. However, in order to display the internal configuration of the housing 230, the top surface of the housing 230 is removed. The housing 230 can be formed as a flat surface (e.g., a hexahedron) to define a predetermined inner chamber 232. The housing 230 may also be formed in accordance with the shape of the slot of the body. The casing 230 such as an optical disk drive structure can also be applied to the third embodiment, but the present invention is not limited thereto. A main substrate 234 can be fixed to the inner chamber 232 of the housing 230. The main substrate 234 can be provided with various components for receiving and transmitting digital broadcast signals. The main substrate 234 can hold communication chips such as digital broadcast chips or other related sets of 20 pieces. In the third embodiment, the components are not labeled with the symbol for convenience. The main substrate 234 can be mounted in a more rearward position in the inner chamber 232 of the housing 230. Since the inner chamber 232 of the body 230 is wider than the main substrate 243, in order to electrically connect the main board and the receiver, the main substrate 234 is disposed as far as possible to the connector 13 1312920. The main substrate 234 can be fixed to the housing 230 by screws 234. For example, the main substrate 234 can be fixed to the protrusion (not shown) of the bottom surface of the housing 230 by the rivet 234, thereby fixing the main substrate 234 to the housing 23 〇. A connector 236 that can be disposed outside the housing 230 can be mounted on the outer surface of the rear wall. The connector 236 is electrically connected to the transmitter-receiver to components mounted on the body 10 or the motherboard. The connector 236 can be fixed to a connector substrate 237 (Connector substrate). The connector substrate 237 can be mounted (e.g., mounted in parallel) on the inner side wall on the rear side where the connector 236 is provided. The connector substrate 237 and the main 10 substrate 234 are electrically connected to each other via a connector 237'. The connectors 237 are respectively fixed to the connector substrate 237 and the main substrate 234, and are electrically connected to the two elements. An antenna substrate 240 can be mounted to the inner chamber 232 to be electrically coupled to the main substrate 234 via a transmission line 238. The antenna substrate 240 can also be fixed to the housing 230 by screws 240, 15. Although the antenna substrate 240 can be integrated into the main substrate 234, the area of the antenna substrate 240 can be made larger. Therefore, in the third embodiment, the main substrate 234 and the antenna substrate 240 are separated into two. Reduce or reduce the area to a minimum. In addition, if the main substrate 234 and the antenna substrate 240 are respectively fabricated, noise interference which may occur due to components such as the main substrate 234 and the antenna substrate 240 or the device is reduced or removed, thereby improving the stability. Or use (such as enhanced) grounding and shielding techniques to reduce or resolve the aforementioned noise interference. The antenna substrate 240 can include a filter wafer. Filter Crystal # can be used to eliminate noise in the signal received by an antenna 250. In this example, it is preferred to use - 14 1312920 to have multiple rows of wires or a more flexible transmission line as the transmission line 238. The antenna substrate 240 can be mounted adjacent to the front surface of the housing 230, and the antenna 250 can be mounted adjacent to the antenna substrate 240. A fixing member 251 5 can be fixed to the bottom surface of the housing 230 and adjacent to the antenna substrate 240. The fixing member 251 is electrically connected to the antenna substrate 240. The fixing member 25 1 may have a shaft portion 252 of a predetermined outer shape. The shaft portion 252 may be provided with a joint 253 through which a through hole 253' is passed. The connector 253 is electrically connected to a layout circuit provided on the antenna substrate 240. The connector 253 is operable to rotate and linearly extend the body 10 of the antenna 10. The connector 253 also provides communication between the antenna body 254 and the antenna substrate 240. The antenna body 254 can include a support portion 255, a connecting portion 260, and a front end 262. The support portion 255, the connecting portion 260, and the front end 262 may be a rod and may be made of metal. The support portion 255 and the connecting portion 260 may also be a hollow metal 15 tube. The support portion 255 can be provided with a pressing portion 255'. Since the diameter of the pressing section 255' is larger than the diameter of other portions of the antenna main body 254, the pressing section 255' is pressed against the through hole 253'. Therefore, in addition to the pressing section 255', the outer diameter of the other portions of the antenna main body 254 can be smaller than the inner diameter of the through hole 253', thereby causing the antenna main body 254 20 to operate as the smoothest straight line (e.g., reciprocating operation, etc.). If the configuration of the antenna main body 254 is as described above, the overall weight and size of the antenna can be reduced. The nip 255' can be assigned an outer diameter that is precisely press-fitted to the inner diameter of the through hole 253' of the joint 253. Since the outer diameter of the press-fit section 255' and the inner diameter of the through-hole 253' are greatly dependent on the transmission and acceptance rates of radio waves, the manufacturing tolerance of the size of 15 1312920 can be minimized. The support portion 255 is electrically connected to the joint 253 and is rotatably and linearly actuated in the through hole 253' of the joint 253. However, the pressing section 255' can be pressed against the through hole 253' of the joint 253, so that the pressing section 255' cannot be intentionally rotated, but if an external force is applied more than a preset value of 5, the pressing section 255' can be Rotate or move in a straight line. The support portion 255 can be provided with a flange 256. It is preferable that the outer diameter of the flange 256 is larger than the outer diameter of the other portion of the support portion 255 so that the support portion 255 cannot be detached from the joint 253. The length of the support portion 255 can be designed such that when the flange 256 is hooked on the joint 53, the end of the support portion 255 can extend through a through hole formed in a front surface of the shell body 230 and protrude outside the casing. A joint portion 258 may be disposed between the support portion 255 and the joint portion 260, and the joint portion 258 may be used for the joint portion 260 to fold the support portion 255 at multiple angles. However, the invention is not limited to this. For example, the engaging portion 258 can be engaged with the connecting portion 260 and the supporting portion 255 in a fixed direction. Further, the joint portion 258 can also engage the joint portion 260 and the support portion 255 with each other by a hinge bolt (not shown). The connecting portion 260 has a predetermined length and may include a plurality of hollow tubular bodies and the outer diameters of the tubular bodies are increased in length and are connected to each other. Therefore, the length of the connecting portion 260 can be varied. The maximum outer diameter of the connecting portion 260 is preferably smaller than the inner diameter of the through hole 253', so that the antenna 250 is more easily stretched and contracted inside and outside the housing 230. The front end 262 can be mounted at one end of the connecting portion 260. The front end 262 can be larger in diameter. The front end 262 can additionally be equipped with an enhanced receiving device. Additionally, the front end 262 can protrude beyond the housing 230 at different lengths. The front end 262 can be provided with an engaging portion 264 having an outer diameter larger than a through hole formed in the front surface of the casing 230. Therefore, the antenna body 254 cannot be completely stored in the inner chamber 232 of the housing 13 of the 13 1312920. A pressing section 265 can be adjacent to the engaging section 264. The outer diameter of the press section 265 is preferably equal to the inner diameter of the through hole 253' of the joint 253. For example, since the outer diameter of the pressing section 265 is equal to the outer diameter of the pressing section 255', the antenna 250 is fixed to the fixing member 251 when the antenna 250 is housed in the housing 230. According to this, the antenna 250 cannot protrude outside the casing 230. A flap 270 can be protruded from the bottom surface of the inner chamber 232 of a housing 230. One of the surfaces of the flap 270 may be provided with a block 272. A conduit 274-end can correspond to the loop insert 272. The insert 272 can secure one end of the conduit 274 to the flap 270. The conduit 274 can be used to actuate the connection portion 260 of the antenna body 254 and the support 10 portion 255 and direct the antenna body 254 to be mounted in the interior chamber 232. The other end of the conduit 274 can be inserted into the fixture 251. The inner diameter of the conduit 274 is preferably sufficient to provide the antenna body 254 for actuation and collection in the conduit 274. Figure 10 is an exploded perspective view of a fourth embodiment of the present invention for a transmitter-receiver of a portable computer. Figure 11 is an exploded perspective view showing the antenna and the catheter in the fourth embodiment of the present invention. As shown in Figures 10 and 11, a transmitter-receiver profile can be defined by a housing 330. In order to show the internal configuration of the housing 230, the top surface of the housing 330 is removed from the drawing in FIG. The housing 330 is a flat surface (e.g., a hexahedron) 20 constituting a predetermined inner chamber 332. The housing 330 may also differ depending on the shape of the slot of the body 10. A casing such as an optical disk drive can also be applied to the fourth embodiment. A substrate 334 can be fixed to the inner chamber 332 of the housing 330. The substrate 334 can be provided with various components for receiving and transmitting digital broadcast signals. For example, substrate 334 can hold communication chips such as digital broadcast wafers or other related components. 17 1312920 In the fourth embodiment, the components are not labeled with the symbol for convenience. The substrate 334 can be mounted in a position in the chamber 332 of the housing 330 adjacent to the front surface (e.g., when one side of the body is exposed to the housing 30 when the housing 330 is inserted into the slot of the body 10). Substrate 334 - the sides do not need to be in contact with the front surface. The substrate 334 can be mounted adjacent to the front surface to reduce or minimize interference with the motherboard mounted to the body 10. The I substrate 334 can be fixed to the housing 330 by screws 334'. For example, the substrate 334 can be fixed to the protrusion (not shown) of the bottom surface of the housing 330 by the screw 334', thereby fixing the substrate 334 to the housing 330. A connector 336 that can be protruded from the outside of the housing 330 can be provided with a surface outside the rear wall. The connector 336 is electrically connected to the transmitter/receiver to components fixed to the body 10' or the motherboard. The connector 336 can be fixed to a connector substrate 337. The connector substrate 337 can be mounted to the housing 330 (as on the inside of the wall after the connector 336 15 is provided). The connector substrate 337 and the substrate 334 may be coupled to each other via a flexible transmission line 338 or the like. • The substrate 334 can be used not only to fix the above-mentioned digital broadcast related wafer, but also to fix the components related to the antenna 350. However, the invention is not limited to this. Since the substrate 334 is fixed with a plurality of components, noise 20 interference between the components may occur. However, technologies such as grounding and shielding can be used to effectively reduce or even solve the aforementioned noise interference problem. The antenna 350 can be mounted on one side of the housing 330 adjacent to the substrate 334. On the side, a fixing member 351 can be fixed on the bottom surface of the housing 330 and adjacent to the substrate 334. The fixing member 351 and the substrate 334 can transmit signals to each other. The 18 1312920 retaining member 35A can include a shaft 352 having an existing shape. Further, a connector 353 is provided through the through hole 353, and the connector 353 is electrically connected to the layout circuit provided on the substrate 334. The connector 353 can support the antenna body 354 while providing communication between the antenna body 354 and the substrate 334. 5 10 15 20 The antenna body 354 can include a support portion 355, _ front = 362. However, the invention is not limited to this. The support portion 355, the connecting portion 36, and the pinch 362 may be a rod body and may be made of metal or the like. The support portion 355 and the connecting portion 360 may also be a hollow tube body made of a conductive material for transmitting and receiving radio waves. The supporting portion 355 can be provided with a pressing portion 355. The pressing portion 355 has a diameter larger than that of other portions of the antenna main body 354, and the pressing portion 355 is pressed to the through hole 353'. Therefore, in addition to the pressing section 355, the outer diameter of other parts of the antenna main body 354 can be less than or equal to the inner diameter of the through hole 353, thereby making the antenna main body 354 perform the smoothest operation (such as linear operation, etc.) c> The configuration of 354 is as described above, which reduces the overall weight and size of the antenna. The pressing section 355 can be fitted with an outer diameter which can be precisely pressed against the through hole 353 and the inner diameter. Since the outer diameter of the pressing section 355' and the through hole 253 have an extremely large relationship with the transmission and acceptance rate of radio waves, it is preferable that the manufacturing tolerance of the dimensions is minimized. The support portion 355 can be electrically connected to the joint 353, and can rotate and straighten at least in the through hole 353 of the joint 353. However, the pressing portion 355 is preferably pressed against the through hole 353 of the joint 353, so that the pressing portion 355' cannot be rotated, but the pressing portion 355' can be rotated if a force exceeding a preset value is applied. Or act like a straight line. The support portion 355 can be provided with a flange 356. The outer diameter of the flange 356 can be 19 1312920 larger than the outer diameter of the other portions of the support portion 355, so that the support portion 355 cannot be detached from the joint 353. The length of the support portion 355 can be designed such that when the flange 356 is drawn to the joint 353, the end of the support portion 355 can extend through a through hole formed in the front surface of the housing 330 and protrude outside the casing. 5 A joint portion 358 may be disposed between the support portion 355 and the connecting portion 360. The engaging portion 358 is adapted to selectively actuate the support portion 35 5 by the connecting portion 360 (e.g., multi-angle folding, etc.). The engaging portion 358 is also adapted to allow the connecting portion 360 to fold the supporting portion 355 at an angle. For example, the engaging portion 358 can engage the connecting portion 360 and the supporting portion 355 with each other by a hinge bolt (not shown). However, the present invention is not limited to this. The connecting portion 360 can be provided with a predetermined length and includes a plurality of hollow tubular bodies whose outer diameters are increased in length and are connected to each other. Therefore, the length of the connecting portion 360 can be varied. The maximum outer diameter of the connecting portion 360 is preferably smaller than the inner diameter of the through hole 353', so that the antenna 350 is more easily stretched inside and outside the housing 230. The front end 362 may be provided at the end of the connecting portion 360. The front end 360 can have a larger diameter. Additional structures (e.g., parts or the like) may be provided at the front end 362 to increase the rate of reception. The front end 362 that protrudes from the housing 330 can have a variety of designs. The front end 362 can be provided with an engaging portion 364. The outer diameter of the engaging portion 364 can be larger than the inner diameter of the through hole provided on the front surface of the housing 330. Therefore, the antenna main body 254 cannot be completely stored in the inner chamber of the housing 330. 332. A pressing section 365 can be adjacent to the engaging section 364. The outer diameter of the pressing section 365 may correspond to the inner diameter of the through hole 353' of the joint 353. For example, since the outer diameter of the pressing section 365 is equal to the outer diameter of the pressing section 355', when the antenna 350 is housed in the housing 330, the antenna 350 is fixed to the fixed piece 13 1312920 piece 35 1 . Accordingly, the antenna 350 cannot be protruded outside the casing 330 due to carelessness or application without the aforementioned external force. A baffle 370 can be protruded from the bottom surface of the inner chamber 332 of a housing 330. One of the surfaces of the flap 370 may be provided with a block 372. A conduit 374-end can correspond to the loop 5 insert 372. The insert 372 can secure the end of the conduit 374 to the flap 370. However, other configurations may be applied to secure and support the conduit 374. The conduit 374 can support the support portion 355 of the antenna body 354 or prevent the antenna body 354 from being deep inside the housing 330. The conduit 374 can be used to guide the connection portion 360 of the antenna body 354 and the support 10 portion 355, and to guide the position of the antenna body 354 in the inner chamber 332. The other end of the conduit 374 can be inserted into the fixing member 351. The inner diameter of the conduit 274 is sufficient to provide the antenna body 354 for actuation and storage therein. However, the antenna body 354 does not have to include a front end 362. For example, there is only the connecting portion 360 without the front end 362, and the antenna main body 354 is fully inserted into the housing 330, and the connecting portion 360 can be designed with a length protrusion (in a desired length) on the front surface of the housing 330. Outside. In other words, the antenna 350 can extend within the housing 330. The operation of a digital broadcast transmission for a portable computer in the embodiment of the present invention will be described herein. The method of using the digital broadcast transmission-20 receiver in the embodiment will be described in detail herein with reference to Figs. 2 to 12(b), but the present invention is not limited thereto. When the transmitter-receiver of the embodiment of the present invention is used, it can be selectively inserted into a slot opened in a portable computer body. For example, the transmitter-receiver can be an expansion device such as a compact disc drive, a slot-type spare battery or a 21 . 1312920 Launch unit and similar plug-in devices. When the user wants to view the digital broadcast using the portable computer, the user can insert the transmitter-receiver of the embodiment of the present invention into the slot of the body 10. If the transmitter-receiver is inserted into the slot of the body 10, the connector 36 can be electrically connected to the 5 motherboard (in the body 10) to transmit the required power and signals to the main substrate (the main substrate 34). The user can pull the antenna body 54 out of the housing 3 to enhance its reception. φ As shown in the state of use in Fig. 2, the front end 62 of the antenna main body 54 can be pulled out by hand. When the front end 62 is pulled out, the support portion of the antenna main body 54 and the connecting portion (6) are pulled out of the casing 30 at the same time. Further, as shown in the state of use of Fig. 2, the antenna can be linearly actuated so that the connecting portion 60 passes through the through hole 53 formed in the joint 53 of the boss portion 52. After the connecting portion 60 passes through the joint 53, the supporting portion 55 can continue to pass through the through hole 53 of the joint. The antenna main body 54 is pulled out from the casing 30 until the flange % of the support portion 55 is engaged with the joint 15 53. Figure 4a shows the state in which the antenna body 54 is pulled out of the housing 30. At this time, only the end of the support portion 55 can protrude beyond the casing 3, and the splicing portion 60 is completely extended beyond the casing 3, but the present invention is not limited thereto. In addition, the connecting portion 60 can be connected to the supporting portion 55 via the pivoting connection with the engaging portion 68, whereby the user can adjust the antenna to search for the best receiving position. When the connecting portion 60 is folded at the engaging portion 68, the supporting portion 55 is rotatable in the through hole 53' of the joint 53. The map shows the status of use. When the length of the connecting portion 60 or the like is adjustable, the position of the antenna main body 22 1312920 can be set by adjusting the length of the connecting portion 60 in accordance with the optimum receiving orientation. The length of the support portion 55 or the front end 62 can also be adjusted. The broadcast signal transmitted and received by the antenna main body 54 can be transmitted to the connector 53 via the antenna main body 54 and then transmitted to the filter wafer 42 fixed to the antenna substrate 40. The noise in the signal is removed by the filter wafer 42 and transmitted to the 5 main substrate 34 via the transmission line %. Then, the signal is transmitted to the chip of the main substrate via the connector 36, and the motherboard converts the signal into an image to be played on the screen 显示器 of the display 12, and the sound is played through the speaker. In this way, the user can watch the broadcast. 5 and 6 are a second embodiment of the present invention in which the antenna body 154 can be moved by the conduit 174 in the housing 130. Therefore, the antenna body 154 can move more accurately within the housing 130, which can reduce the probability of damage to the antenna body 154. When the antenna body 154 protrudes out of the housing 130, the pressing portion 155' can be pressed against the through hole 153 of the fixing member 151, so that the antenna body 154 cannot be moved or suspended in the housing due to carelessness. . In other words, the antenna main body 154 can hold the state outside the casing 130. The flange 156 is engageable with the fixing member 151 so that the antenna body 154 can no longer extend outwardly of the housing 3. As shown in Figs. 9a to 9c, the operation of the transmitter_receiver of the third embodiment will be explained here. If the transmitter-receiver of the embodiment is inserted into the slot 236 of the body 1, the connector 236 can be electrically connected to the motherboard. 2〇 The user can pull the antenna body 254 out of the housing 23 to enhance its reception. As shown in the state of use in Figure 7, the front end 262 of the antenna body 254 can be pulled out by hand. When the front end 262 is pulled out of the support portion 255 of the antenna main body 254 and the connecting portion 260, the casing 23 is simultaneously pulled out. Further, as shown in the state of Fig. 7, the antenna is linearly actuated so that the connecting portion 26 is straightly passed through the through hole 253' of the joint 23 1312920 253 which is opened to the shaft portion 252. When the connecting portion 260 passes through the joint 253, the supporting portion 255 can continue to pass through the through hole 253' of the joint 253 in a straight line. The antenna body 254 is pulled out by the housing 230 until the flange 256 of the support portion 255 is engaged with the joint 25 3 . Fig. 9a shows the state in which the antenna body 254 is pulled out of the housing 230. As shown in Fig. 9a, only the end of the support portion 255 can protrude beyond the housing 230. At this time, the connecting portion 260 has completely protruded from the outside of the housing 230. Therefore, the pressing portion 255' of the support portion 255 can be pressed against the through hole 253' of the joint 253, so that the antenna main body 254 cannot be moved by carelessness. For example, the antenna main body 254 can be actuated to the fixing member 251 only when a force is applied to the antenna main body 254 beyond a predetermined value. Next, in order for the user to adjust the antenna to find the best receiving position, the connecting portion 260 can actuate the support portion 255 (by pivoting with the engaging portion 258). When the connecting portion 260 is folded at the pivotal portion of the engaging portion 258, the supporting portion 255 is rotatable in the through hole 253' of the joint 253. Fig. 9b shows the state of use, however, it may further comprise a plurality of joints. In the third embodiment of the present invention, the length of the connecting portion 260 can be adjusted. Therefore, as shown in Fig. 9c, the position of the antenna body 254 can be set by adjusting the length of the connecting portion 260 in accordance with the optimum receiving orientation. Additionally, the antenna body 254 can be received within the housing 20 230 when the antenna 250 is not in use. For example, when the user pushes the antenna body 254 into the housing 230, the antenna body 254 can move and be guided into the tube of the catheter 274. The antenna main body 254 is continuously advanced until the support portion 255 is supported by the flap 270. The flap 270 blocks the antenna body 254 from pushing beyond its preset length. When the antenna body 254 is pushed into the housing 24 1312920 230 by the length when the connecting portion 260 is fully received, the pressing portion 265 can be pressed against the through hole 253' of the fixing member 251. This is why the fixing member 251 is fixed to the front surface of the casing 230 and the pressing portion 265 is provided with a predetermined length. Therefore, even if the housing 230 is tilted downward, the antenna 250 cannot fall out of the housing 230. In general, the front end 262 can be exposed outside the housing 230 even when the antenna main body 5 254 is housed in the housing 230, but the present invention is not limited thereto. As shown in Figs. 12a and 12b, the operation of the transmitter-receiver of the fourth embodiment will be explained here. If the transmitter-receiver of the embodiment is inserted into the slot of the main body 10, the connector 336 can be electrically connected to the motherboard. 10 Further, the user can pull the antenna body 354 from the housing 330 to enhance its reception. As shown in the state of use in Fig. 10, the front end 362 of the antenna body 354 can be pulled out by hand. When the front end 362 is pulled out, the support portion 355 and the connecting portion 360 of the antenna main body 354 are simultaneously pulled out of the casing 330. Further, as shown in the state of Fig. 10, the connecting portion 360 penetrates through the through hole 353' of the joint 353 of the boss portion 352. When the connecting portion 360 passes through the joint 353, the supporting portion 355 can continuously pass through the through hole 353' of the joint 353. The antenna body 354 is pulled out by the housing 330 until the flange 356 of the support portion 355 is engaged with the joint 353. Fig. 12a shows a state in which the antenna main body 354 is pulled out of the casing 330. At this time, only the end of the support portion 355 can protrude beyond the housing 33020, and the connecting portion 360 has completely protruded out of the housing 330. The pressing portion 355' of the support portion 355 can be pressed against the through hole 353' of the joint 353, so that the antenna main body 354 cannot be moved by carelessness. For example, the antenna body 354 can be actuated to the fixture 351 only when a force is applied to the antenna body 354 beyond a predetermined value. 25 1312920 And in order for the user to adjust the antenna to find the best receiving orientation, the connecting portion 360 can actuate the support portion 355 (by pivoting with the engaging portion 358). If the connecting portion 360 is folded at the joint of the engaging portion 358, the supporting portion 355 can rotate in the through hole 353' of the joint 353. Fig. 12b shows the use state of the junction. The length of the connecting portion 360 can be adjusted. Therefore, the user can move the front end 3 6 2 by adjusting the length of the connecting portion 360 to have an optimum receiving position. When the antenna 350 is not in use, the antenna body 354 can be incorporated into the housing 230. For example, when the user pushes the antenna body 354 into the housing 330, the antenna 10 body 354 can move and be guided into the tube of the catheter 374. The antenna main body 354 is continuously advanced until the support portion 355 is supported by the flap 370. The flap 370 blocks the antenna body 354 from being pushed into the housing 330 by a predetermined length. When the antenna body 354 is pushed into the housing 330 with the length of the connecting portion 360 fully received, the pressing portion 365 can be pressed against the through hole 353' of the fixing member 351. This system 15 is responsible for fixing the fixing member 351 adjacent to the front surface of the housing 330 and the pressing portion 365 to have a predetermined length. In this state, even if the housing 330 is tilted downward, the antenna 350 does not fall out of the housing 330. Even when the antenna body 354 is housed in the housing 330, the front end 362 can be exposed outside the housing 330. According to an embodiment of the present invention, a digital broadcast transmission-receiving device for a portable computer and a method thereof can be used, and the digital broadcast can be viewed by a conventional portable computer. Since the user can insert the transmitter-receiver into the portable computer as needed, the expandability of the portable computer also increases. In addition, since the transmitter-receiver of the embodiment is shorter and lighter, the portability and the quality of the signal transmission and reception are relatively improved. 26 1312920 By embedding an antenna-slot expansion device, the transmit_receiver of an embodiment can provide an antenna with a full charge and length (such as a retractable antenna body) to effectively support digital broadcast services. Do it . For example, the transmitter-receiver of the embodiment can support digital broadcasting services such as DMB or HDTV. In addition, embodiments of the present invention may also support an interactive digital broadcast service. 10 15 20 References in this specification to any of the 'an embodiment,', the embodiment, and the 'example embodiment', and the meaning of the embodiment includes at least one embodiment of the invention.

Moreover, in order to make the invention more susceptible to the steps of the method, the steps may be described in separate steps, but the individual steps need not be interpreted in the order in which they are arranged. change. In some cases, some steps can be rearranged or reversed at the same time. As described above, the digital broadcast transmission-receiving method of the embodiment applied to a portable computer has an advantage. For example, when the transmitter/receiver of the embodiment of the present invention is inserted into a portable electric material, the maker can externally connect a larger screen and a more textured sound device for viewing the digital broadcast. Further, the emission of the embodiment of the present invention. The receiver can be plugged into (for example, a slot-type expansion device) on the body of the portable computer. Since the transmitting receiver of the embodiment of the present invention can be applied to a general-purpose portable computer, it is not necessary to change it (such as an installation-adapter) for installation, thereby reducing the cost of the transmitting/receiving device. Then ^°, - the solid is penetrated by the antenna; the t piece can be fixed on the bottom surface of the housing - the antenna base 27 1312920 board, without being directly fixed on the antenna substrate, so that the antenna is installed to the south of the casing, Even (five) (overall) launch. The height of the receiver can also be reduced. Therefore, the transmitter-receiver has the advantage that it can also be applied to a portable computer that is lighter, thinner and shorter. Since the substrate mounted on the transmitter_receiver can be installed at a position far away from the motherboard of the 5-band computer, the interference between the motherboard and the substrate can be reduced, and the transmission and reception effects of the digital broadcast can be improved.
