[Prior art]
隨著電腦工作時脈不斷提升.，資料儲存裝置的規格也不斷翻 新。傳統的平行ATA(Parallel ΑΤΑ)儲存裝置，因為其傳輸速度 已無法再突破，而有了串列ΑΤΑ ( Serial-ATA ; SATA )的出現。串 列ΑΤΑ藉由高時脈來達到更高的頻寬速度，而將傳輸速度大幅提 昇。串列ΑΤΑ儲存裝置打破了儲存裝置傳輸的瓶頸，串列ΑΤΑ規 格制定初期的頻寬速度為L5Gb/s，而其規格目前可達到的·最高頻 寬則為4X模式下的6Gb/s。由此可知，串列ATA規袼的頻寬速度 遠高於傳統平行ΑΤΑ的頻寬速度。 X 如同傳統的平行ΑΤΑ鍺存裝置一般，串列ΑΤΑ儲存裝置也有外 接裝置的需求，以方便使用者安裝及替換串列ΑΤΑ儲存裝置。但 是因為目前的串列ΑΤΑ的傳輸規格中，其並沒有任一接腳是用來 傳遞讀寫狀態（Read/Whte state)的訊號，所以在習知採用串 列ΑΤΑ傳輸介面的外接裝置令，也就沒有顯示儲存裝置讀寫狀態 的燈號。如此一來，因習知的串列ΑΤΑ介面的外接裝置缺少顯示 儲存裝置讀寫狀態的指示燈，使用者在使用過程令會無法得知儲 存裝置目前的狀態，而造成了使用者使用時的不便。 5 1237763 【發明内容】 因此本發明之主要目的在於提供一種具有狀態指示燈的串列 ΑΤΑ儲存裝置之外接裝置，使用者可依據該狀態指示燈的燈號來判 斷該串列ΑΤΑ儲存裝置的運轉情形，以解決上述串列ΑΤΑ儲存裝 置之外接裝置無法顯示讀寫狀態的問題。 ' 根據本發明之申請專利範圍7 π狗路一裡甲夕丨】ΑΤΑ (Serial Advanced Technology Attachment ; SATA)規格之外接裝置，用來 外接^料儲存裝置。該資料儲存裝置包含有一資料傳輸介面用 來傳遞一資料訊號，以及—資料儲存媒介用來儲存 裝”含有-串列m連接埠、一電源連接槔、—處理電： '卜接 燈以及一狀態指示燈。該串列m連接埠連接該資 輸，1面與—電子裝置1來傳送該資料訊號。該電源連接埠電連 接邊貧料儲存裝置與-電源，用來接收該電源之電力供應，以供 亥貝料儲存裝置所需之電力。該處理電路用來依據該資料訊號 :產生一狀態訊號。該電源指示燈用來顯示該資料儲存裝置的電 源供應狀態。該狀態指示燈用來依據該狀態訊號來顯示該資料儲 存裝置的讀寫狀態。 、 本發明夕卜接裝置的其中—項特點是該外接裝置之處王里電路並聯 於该串列ΑΤΑ連接淳，用以依據該串列ATA連接淳所傳送的資料 訊號，來產生讀寫訊號以控制該狀態指示燈。 本發明外接裝置的另一項特點是該訊號指示燈的裝設位置具多 種的選擇性’例如可將該訊號指示燈裝設在該外接裝置的殼體 上、一吼號連接線上或是該串列連接埠的附近。 6 1237763 【實施方式】 請參考圖-及圖二，圖-為本發明第一實施例外接裝置i 接至一電子裝置60之示意圖，圖二為圖一外接裝置1〇之—串 ΑΤΑ接頭11之示意圖。外接裝置10包含有—串^ ata接頭u : 串列ΑΤΑ接頭11係'連接於一訊號連接線4〇和_電源連接線5〇， 而外接裝置10則是藉由串列ΑΤΑ接頭u、訊號連接線4G以 源連接線50來與一電子裝置（例如個人電腦）6〇相並 訊號與電力至電子裝置6〇。串列ATA接頭U包含有一串列. 連接埠14、一電源連接槔16，争列ΑΤΑ連接4 14斑訊號連 40連接’用以依據串列ΑΤΑ之規格來傳遞資料而電源連、、 與電源連接線5G連接。電源速接線5()所傳送的電力可以由= 一 Γ:電源提供’以提供電力于外接裝置10及電子 裝置60使用。此外，訊號連接線4Q與電 獨立的纜線或是結合成單一條纜線。 Λ 50叮疋—條 請參考圖三’圖三為圖—外接裝置10之功能方塊圖。在本實 ig是用來裝設及外接—儲存裝置π，以存_ Ϊ料。在本實施财，儲存裂置3°為-台串 步詈3(1 if ’但須說明的’本發明之外接裝置1G所裝設的儲存 裝置30並不以硬碟機為限。外接装置1〇包含有 、With the continuous improvement of computer operating clock, the specifications of data storage devices have also been continuously updated. Traditional parallel ATA (Parallel ATA) storage devices, because their transmission speed can no longer break through, have emerged as Serial ATA (Serial-ATA; SATA). The serial ΑΑΑ achieves higher bandwidth speeds by high clock speeds, which greatly increases the transmission speed. The serial ATFA storage device breaks the bottleneck of the storage device transmission. The initial bandwidth speed of the serial ATFA specification is L5Gb / s, and the highest achievable current specification is 6Gb / s in 4X mode. It can be seen that the bandwidth speed of the serial ATA protocol is much higher than the bandwidth speed of the traditional parallel ATA. X Like the traditional parallel ΑΑΑ germanium storage device, the serial ΑΑΑ storage device also requires an external device to facilitate the user to install and replace the serial ΑΑΑ storage device. However, since the current serial ATA transmission specifications do not have any pin that is used to transmit the signal of read / write state (Read / Whte state), the external device order of the serial ATA transmission interface is known in the art. That is, there is no light indicating the reading and writing status of the storage device. In this way, because the conventional external device of the serial ATA interface lacks an indicator indicating the read and write status of the storage device, the user cannot know the current status of the storage device during the use process, which causes inconvenience to the user. . 5 1237763 [Summary of the invention] Therefore, the main object of the present invention is to provide an external device connected to a serial ATA storage device with a status indicator.

The processing circuit is used to generate a status signal according to the data signal. The power indicator is used to display the power supply status of the data storage device. The status indicator is used to The reading and writing status of the data storage device is displayed according to the status signal. One of the characteristics of the device of the present invention is that the Wangli circuit of the external device is connected in parallel to the serial ΑΑΑ connection, and is used to comply with the serial The data signals transmitted by the ATA connection are listed to generate read and write signals to control the status indicator. Another feature of the external device of the present invention is the signal indicator There are various options for the installation position. For example, the signal indicator can be installed on the housing of the external device, a roar connection line, or near the serial port. 6 1237763 [Embodiment] Please refer to Figure 2 and Figure 2 are diagrams of an external device i connected to an electronic device 60 according to the first embodiment of the present invention, and Figure 2 is a schematic diagram of a string AATA connector 11 of the external device 10 in Figure 1.
