RW，DVD土RW，DVD-RAM等的可寫入 /刪除·改寫的類型的光碟等的各種光碟。這些光碟形成下 述的媒體，其中，採用光碟裝置對資料進行再現等的處理。 “CD —ROM” ，或 “DVD —ROM” 的 “ROM” 爲 “Read Only Memory” 的簡稱，CD —ROM，或 DVD — ROM 爲讀出 專用的。另外，“CD — R” ，或“DVD±R”的“R”爲 “Recordable”的簡稱，CD — R，或DVD 土R可寫入。另外， “CD —RW” ，或 “DVD土RW” 的 “RW” 爲 “Rewritable” 的簡稱，CD —RW，或DVD土RW可改寫。另外，“DVD — RAM” 爲 “Digital Versatile Disc Ramdom Access Memory” 的簡稱，可讀寫·刪除。 1264710 光碟裝置作爲可採用例如c D，D V D中的任何一個 個的光碟的播放機等而構成。CD播放機，DVD播放機 採用CD和DVD兩種光碟的播放機，按照例如與筆記 的PC，桌上型的PC等組裝的方式使用。PC爲個人電 (Personal Computer )的簡稱。 另外，在構成播放機的播放機主體上，設置有可裝 碟的托盤。該托盤在規定的位置，作爲可裝設CD，或 的形式而形成。這樣的托盤設置於播放機主體的前面 更具體地說，在構成播放機的播放機主體的前面，設 托盤，該托盤可將光碟安裝於光碟裝置內，從光碟裝 排出光碟的托盤。 此外，在光碟裝置主體的基本中間處，設置有驅動 的轉臺。另外，從光碟進行讀出信號的動作的拾取器 於光碟裝置主體上。另外，在光碟裝置的後部，設置電 另外，在光碟裝置的後側面，設置有連接端子，該連 子可與電腦主體連接。 在追記型CD，或可改寫型CD等的記錄型的光碟， 有資料等時，較大的輸出値的雷射從拾取器的雷射二 照射到光碟上，在光碟上記錄資料。在光碟上記錄資料 從拾取器的雷射二極體，射出較大的輸出値的雷射。 爲了從拾取器的雷射一極體，射出輸出較大的輸出 雷射，雷射二極體必須要求較多的電流。流過雷射二 的電流從裝載於構成電路的基板主體上的積體電路流 由此，當在光碟上記錄資料時，從構成電路的積體電 流過較多的電流。由於像這樣構成，在光碟上記錄資料 或兩 ;，可 本型 腦 設光 DVD 置有 置內 光碟 設置 路。 接端 記錄 極體 時， 値的 極體 過。 路， 時， 1264710 從雷射二極體，與積體電路，產生較多的熱量。雷射二極 體和積體電路構成產生較多的熱量的電氣/電子部件。 還從雷射二極體和積體電路以外的其他的電氣/電子部 件，產生熱量。雷射二極體，與積體電路產生的發熱量大 大超過從雷射二極體和積體電路以外的電子部件產生的發 熱。另外，在於光碟上記錄資料時，相對光碟裝置主體， 托盤在關閉的狀態運轉，由此，從雷射二極體產生的熱量’ 從積體電路產生的熱量等蓄積於構成光碟裝置主體的支架 內部。 當從雷射二極體，射出光時，雷射二極體的雷射的振盪 波長依賴於溫度。由此，如果雷射二極體的溫度發生較大 變化，則從雷射二極體射出的雷射的波長也變化。如果通 過雷射二極體本身發出的熱量，積蓄雷射二極體，則從雷 射二極體射出的雷射的波長變化。如果產生這樣的情況， 則不從雷射二極體，射出恒定的波長的雷射。 作爲防止拾取器等的發熱體的溫度上升，防止因過溫度 上升，發熱體的特性惡化的裝置，包括有下述的光碟驅動 器，在該光碟驅動器中，在與主軸馬達的旋轉軸相同的軸 上’設置螺旋槳（propeller )，或風扇，伴隨主軸馬達的 旋轉產生風，該風位於拾取器、馬達、電路等的發熱體， 對這些發熱體進行冷卻（例如參照日本專利公開公報特開 2002 — 25 24 3號文獻的第1，3頁，第6，11，14，15圖等）。 但是，在該過去的光碟裝置中，由於在構成光碟裝置主 體的支架的內部’容易積蓄熱量，故難於進行雷射二極體， 積體電路的放熱。如果形成進行雷射二極體，積體電路的 1264710 放熱困難的結構，則有雷射二極體，積體電路，因 出的熱量等而蓄熱的危險。 如上所述，由於當從雷射二極體，射出雷射時， 二極體的雷射的振盪波長依賴於溫度，故如果雷射 的溫度變化較大，則從雷射二極體射出的雷射的波 化。如果因通過雷射二極體本身發出的熱量，雷射 的溫度異常高，則從雷射二極體射出的雷射的波長 在產生這樣的場合，不從雷射二極體，射出恒定的 雷射。 在雷射二極體在異常高溫的狀態動作，在光碟上 料的場合，具有對雷射二極體，光碟產生不利影響的 例如在於雷射二極體處於異常高溫的狀態的條件下 碟上記錄資料的場合，對雷射二極體的性能，雷射 的壽命，記錄於光碟上的資料的品質等造成較大的 像這樣，如果在雷射二極體處於異常高溫的狀態的 下，在光碟上記錄資料，則具有下述的危險，即， 射二極體的壽命變短，另外，雷射二極體的性能變 錄的可靠性不滿足的光碟。 如果具體描述，則在於CD-R等的追記型光碟J: 資料時，較大的電流値的電流流過控製電路所採用 電路，與和積體電路連接的雷射二極體。於是，積 與雷射二極體發熱。在這樣的狀態的場合，雷射二 雷射二極體本身產生的熱量而蓄熱。另外，伴隨該 從積體電路等產生的熱量，雷射二極體的溫度進一 升。由於積體電路發熱，則光拾取器的周邊溫度上 本身發 則雷射 二極體 長也變 二極體 變化。 波長的 記錄資 危險。 ，在光 二極體 影響。 條件 形成雷 化，記 ，寫入 的積體 體電路 極體因 情況， 步上 升。在 1264710 於雷射二極體異常高溫的狀態，在光碟上記錄資料的場 合，具有對雷射二極體的壽命，雷射二極體的性能，記錄 於光碟上的資料的品質造成不利影響的危險。 爲了防止熱量積蓄於光碟裝置的內部的情況，還可通過 在光碟裝置中，設置冷卻用的風扇，避免光碟裝置內的高 溫化。這樣的方式爲例如針對桌上型的PC(圖中未示出）， 形成有效的冷卻方式。桌上型電腦爲桌上型的電腦，即可 在桌上使用的電腦，但是，爲不容易搬運的類型。 由於相對桌上型的PC，筆記本型的PC (圖中未示出） 要求輕量化，輕薄化，故具有形成設置窄型驅動器的光碟 裝置的結構。筆記本型的p c爲與桌上型的P C不同的結 構。在筆記本型的PC中，顯示器與PC主體爲一體結構， 相對PC主體，顯示器折疊，由此，形成較薄的尺寸。筆記 本型的P C爲在從平面觀看它時’爲大約爲A4的尺寸，或 其以下的尺寸的廣泛應用的個人電腦，也稱爲書型PC。像 這樣，重要的是筆記本型的PC的整體是緊湊的，可容易搬 運。 由於筆記本型的PC用的光碟裝置爲薄型，故人們認爲 從光碟裝置的設置空間不足的方面來說，在筆記本型的PC 用的光碟裝置中，設置防止光碟裝置的溫度上升的冷卻用 風扇的方面是不合理的。爲了在筆記本型PC用的光碟裝置 中’設置防止光碟裝置的溫度上升的冷卻用風扇，必須擴 大光碟裝置的部件的設置空間。在筆記本型PC用的光碟裝 置中，擴大部件的設置空間會導致筆記本型PC的整體尺寸 的增加。另外，在這樣的筆記本型P C中，重量增加。由於 1264710 這樣的情況與筆記本型PC的使用者的要求相反，故不設計 /製造這樣的裝置。 另外，在筆記本型PC中，當僅僅採用電池時，由於可 至少在較長的時間範圍內使用PC，故必須極力地抑製耗電 量，由於這樣的情況，消耗PC的電力的冷卻用風扇等的冷 卻裝置設置於筆記本型PC用的光碟裝置，該情況與筆記本 型PC的使用者的要求相反，人們希望通過其他的方式，對 筆記本型PC的光碟裝置進行冷卻。 此外，當在光碟裝置中裝設光碟，光碟旋轉時，如果伴 隨光碟的旋轉而產生的空氣流形成紊流，則通過形成紊流 的空氣流，光碟，光碟裝置產生較小的振動，或從光碟， 光碟裝置，產生較低噪音。 【發明內容】 本發明目的提供一種解決該問題的光碟裝置。具體來 說，本發明的目的在於針對該方面，提供放熱特性優良的 光碟裝置。 爲了實現該目的，本發明的申請專利範圍第1項所述的 光碟裝置包括光碟裝置主體；托盤，該托盤可相對光碟裝 置主體實現開閉；在該托盤上，設置裝設光碟的光碟裝設 部，該光碟位於形成該光碟裝設部的壁的內側，伴隨該光 碟旋轉，在該光碟裝設部，產生空氣流，其特徵在於在構 成該托盤的該壁中，開設有排放口，該排放口從該壁的內 側，朝向該壁的外側，使該空氣流通過，在該光碟裝置主 體上，開設有使光碟裝置主體內的空氣排出的排出口。 通過該方案，避免在光碟裝置中積蓄熱量，光碟裝置內 -10- 1264710 的熱量容易排到光碟裝置的外部。通過設置於光碟裝置內 的光碟的旋轉，空氣流產生於托盤的光碟裝設部。該空氣 流從設置於托盤的光碟裝設部的壁上的排放口，朝向設置 於光碟裝置主體上的排出口流動。於是，光碟裝置主體內 的熱量通過空氣流，從光碟裝置主體的排出口，排向光碟 裝置主體的外部。由此，可提供放熱特性優良的光碟裝置。 本發明申請專利範圍第2項所述的光碟裝置涉及本發明 申請專利範圍第1項所述的光碟裝置，其特徵在於該排放 口設置於從該托盤的前側，朝向該托盤的後側，產生空氣 流的位置；該排出口設置於該光碟裝置主體後側。 通過該方案，伴隨光碟的旋轉，在托盤的光碟裝設部產 生的空氣流通過設置於形成托盤的光碟裝設部的壁上的排 放口，朝向托盤的後側流動。在形成托盤的光碟裝設部的 壁的內側產生的空氣流通過設置於托盤上的排放口而排 出，排出到形成托盤的光碟裝設部的壁的外側。另外，該 空氣流主要從設置於光碟裝置主體的後側的排出口而排 出。結果，光碟裝置本體內部的熱，迅速地排到光碟裝置 本體的外部。於是，當伴隨光碟的旋轉而產生的空氣流形 成紊流時，通過紊流的空氣流，具有光碟，光碟裝置產生 振動，從光碟，光碟裝置，產生噪音的危險。但是，在形 成托盤的光碟裝設部的壁上，開設有空氣流通過的排放 口，空氣流從形成托盤的光碟裝設部的壁的內側，向壁的 外側排出，對空氣流進行整流。於是，當在光碟裝置中設 置光碟，使光碟旋轉時，避免從光碟，光碟裝置，產生振 動，噪音的情況，可降低光碟裝置的振動，降低其噪音。 -11 - 1264710 本發明申請專利範圍第3項所述的光碟裝置涉及本發明 申請專利範圍第1項所述的光碟裝置，其特徵在於該壁包 括基壁與側壁，該基壁與該光碟的平面部相對應，該側壁 從該基壁立起，與光碟的外周部相對應，該排放口設置於 該側壁上。 通過該方案，在托盤的光碟裝設部產生的空氣流通過設 置於形成托盤的光碟裝設部的壁上的排放口而排出，容易 從形成托盤的光碟裝設部的壁的內側，向外側排出。旋轉 的光碟的平面部，與構成靜止的托盤的光碟裝設部的基壁 之間，主要產生空氣流。由於空氣流通過的排放口設置於 與構成托盤的光碟裝設部的基壁而立起的光碟的外周部相 對應的側壁上，故在托盤的光碟裝設部產生的空氣流有效 地通過托盤的排放口而排放。通過該空氣流，光碟裝置主 體內的熱量可有效地排到光碟裝置主體的外面。 本發明申請專利範圍第4項所述的光碟裝置涉及本發明 申請專利範圍第1項所述的光碟裝置，其特徵在於進行包 括對該光碟控製的控製的基板設置於該光碟裝置主體的後 側，對應於該基板，在該托盤的基本中間部的後側的壁上， 開設有該排放口。 通過該方案，在托盤的光碟裝設部產生的空氣流容易吹 到設置於光碟裝置主體的後側。當使光碟旋轉時，光碟和 托盤接納於光碟裝置主體的內部。此時，由於在於托盤的 基本中間部的後側，形成光碟裝設部的壁上，設置空氣流 通過的排放口，故例如當從平面透視光碟裝置內部時，在 托盤的基本中間部的後側，設置於光碟裝設部的壁上的空 -12- 1264710 氣流通用的排放口，與裝設於光碟裝置主體的後側的基板 實現重合。由此，在托盤的光碟裝設部產生的空氣流通過 設置於托盤上的排放口而排出，容易吹到裝設於光碟裝置 主體的後側的基板上。於是，設置於光碟裝置主體的後側 的基板的熱量有效地由在托盤的光碟裝設部產生的空氣流 所奪取。另外，如果構成這樣的光碟裝置，則容易將設置 於基板上的積體電路的溫度保持在允許範圍內的溫度。於 是，設置於基板上的積體電路可在溫度具有富裕的狀態使 用。 本發明申請專利範圍第5項所述的光碟裝置涉及本發明 申請專利範圍第1項所述的光碟裝置，其特徵在於進行該 控製的基板設置於構成該光碟裝置主體的支架上，該基板 爲在基板主體表面背面上設置有電氣/電子部件的雙面基 板，該雙面基板在與該支架的基壁離開的狀態，設置於支 架上，開設於構成該光碟裝置主體的支架中的排出口將該 雙面基板的一側面的空氣流，與該雙面基板的另一側面的 空氣流排到光碟裝置主體的外側。 通過該方案，設置於構成光碟裝置主體上的支架上的兩 面基板的一個側面和另一側面容易與托盤的光碟裝設部產 生的空氣流接觸。由於雙面基板在與構成光碟裝置主體的 支架的基板離開的狀態，設置於支架上，故從雙面基板的 一個側面產生的熱量，與從雙面基板的另一側面產生的熱 量排到光碟裝置內的空氣中。另外，從雙面基板的一個側 面產生的熱量，與從雙面基板的另一側面產生的熱量由伴 隨光碟的旋轉而產生的空氣流奪取。另外，奪取了雙面基 -13- 1264710 板的熱量的空氣流從設置於構成光碟裝置主體的支架上的 排出口，排到光碟裝置主體的外側。於是，可通過在托盤 的光碟裝設部產生的空氣流，有效地對設置於構成光碟裝 置主體的支架上的雙面基板的熱量進行冷卻。 本發明申請專利範圍第6項所述的光碟裝置涉及本發明 申請專利範圍第1項所述的光碟裝置，其特徵在於在光碟 裝置主體的內部，實現空氣的流動的導向壁設置於該排放 口，與該排出口之間。 通過該方案，從托盤的光碟裝設部產生的空氣流容易在 光碟裝置主體的內部運動。在設置於形成托盤的光碟裝設 部的壁上的空氣流通用的排放口，與設置於光碟裝置主體 上的空氣流通用的排出口之間，設置有使空氣流在光碟裝 置主體的內部運動的導向壁，從托盤的裝設部產生的空氣 流容易與導向壁接觸，在光碟裝置主體的內部運動。於是， 可避免在光碟裝置主體內部，局部地產生高溫的部分，可 將光碟裝置主體內的溫度保持在允許範圍內的溫度。 本發明申請專利範圍第7項所述的光碟裝置涉及本發明 申請專利範圍第1項所述的光碟裝置，其特徵在於可對該 光碟的資料進行讀取的拾取器設置於該托盤上，使該拾取 器周邊的空氣流動的導向壁設置於該托盤上。 通過該方案，從托盤的光碟裝設部產生的空氣流與設置 於托盤上的導向壁接觸。由此，使拾取器周邊的空氣流動， 從拾取器產生的熱量容易爲流動的空氣流所奪取。於是， 可避免構成拾取器的雷射二極體處於異常高溫的狀態，因 該高溫，對雷射二極體的性能，雷射二極體的壽命造成不 -14- 1264710 利影響的情況，可從構成拾取器的雷射器，射出長期穩定 的雷射。 本發明申請專利範圍第8項所述的光碟裝置涉及本發明 申請專利範圍第1項所述的光碟裝置，其特徵在於覆蓋該 光碟裝置主體的內部的面板設置於該托盤的前側，在於相 對光碟裝置主體，關閉該托盤時，構成光碟裝置主體的支 架’與設置於該托盤上的面板之間，設置間隙，該間隙形 成吸入α，該吸入口使空氣流入到光碟裝置主體的內部。 通過該方案，從設置於構成光碟裝置主體的支架，與設 置於托盤，覆蓋前側的光碟裝置主體內的面板之間的間 隙’有效地將空氣吸入光碟裝置主體的內部。伴隨設置於 光碟裝置內部的光碟的旋轉，空氣流在托盤的光碟裝設部 中產生。但是，爲了將空氣流從設置於光碟裝置主體上的 排出口 ’有效地排到光碟裝置主體的外側，在光碟裝置中， 必須要求空氣可容易流入的吸入口。如上述，由於在光碟 裝置中’設置有可有效地將空氣吸入到光碟裝置內的吸入 □ ’故通過伴隨使設置於光碟裝置內的光碟旋轉而產生的 空氣的運動，光碟裝置主體內的空氣從光碟裝置的吸入 口 ’流向排出口。於是，可防止熱量積累於光碟裝置的內 部的情況，可將光碟裝置內的溫度保持在使用允許範圍內 的溫度。 本發明申請專利範圍第9項所述的光碟裝置涉及本發明 申請專利範圍第1項所述的光碟裝置，其特徵在於具有該 托盤的光碟裝置主體可設置於薄型的筆記本型電腦中。 通過該方案，可提供不必要求風扇等的特別的冷卻裝 -15- 1264710 置t放熱特性優良的筆記本型電腦用的光碟裝置。最近的 筆記本型計算機具有高性能化，小型化，輕量化，輕薄化 的傾向。如果提高電腦的性能，則從電腦，產生較多的熱 量。由此，在電腦中，必須要求某種冷卻機構。另一方面， 在最近的筆記本型電腦中，要求小型化，輕量化，輕薄化。 風扇等的特別的冷卻裝置等設置於筆記本型電腦中，這會 導致筆記本型電腦的大型化，重量增加。這跟電腦的使用 者的要求相反。但是，如果利用伴隨設置於光碟裝置內的 光碟的旋轉而產生的空氣流，防止光碟裝置內的高溫化， 避免筆記本型電腦的大型化，重量增加。於是，可構成具 有沒有整體尺寸增加，重量增加，緊湊的，放熱特性優良 的光碟裝置的筆記本型電腦。另外，還避免使增加筆記本 型電腦的耗電量。 如上所述，按照本發明申請專利範圍第1項所述的發 明，可避免熱量積蓄於光碟裝置的內部，可容易將光碟裝 置內的熱量排到光碟裝置的外部。伴隨設置於光碟裝置的 內部的光碟的旋轉，可在托盤的光碟裝設部，產生空氣流。 該空氣流從托盤的光碟裝設部的壁上的排放口，流向設置 於光碟裝置主體的排出口。於是，通過空氣流，將光碟裝 置主體內的熱量從光碟裝置主體的排出口，排向光碟裝置 主體的外部。由此，可提供放熱特性優良的光碟裝置。 按照本發明申請專利範圍第2項所述的發明，通過使光 碟旋轉，在托盤的光碟裝設部產生的空氣流通過設置於形 成托盤的光碟裝設部的壁上的排放口，朝向托盤的後側流 動。在形成托盤的光碟裝設部的壁的內側產生的空氣流通 -16- 1264710 過設置於托盤的排放口而排放，向形成托盤的光碟裝設部 的壁的外側排出。另外，該空氣流主要從設置於光碟裝置 的後側上的排出口而排出。於是，可將光碟裝置主體的內 部的熱量，快速地排到光碟主體的外部。另外，具有在伴 隨光碟的旋轉產生的空氣流形成紊流時，因形成紊流的空 氣流，光碟，光碟裝置產生振動，或從光碟，光碟裝置產 生噪音的危險。但是，在形成托盤的光碟裝設部的壁上， 設置空氣流通過的排放口，通過空氣流從形成托盤的光碟 裝設部的壁的內側，向壁的外側流出，對空氣流進行整流。 於是，在光碟裝置中，設置光碟，使光碟旋轉時，可回避 光碟在光碟裝置中的振動發出的雜訊，可降低光碟裝置的 振動，噪音。 按照本發明申請專利範圍第3項所述的發明，在托盤的 光碟裝設部產生的空氣流通過設置於形成托盤的光碟裝設 部的壁上的排放口而排出，其容易從托盤的光碟裝設部的 壁的內側，排到外側。在旋轉的光碟的平面部，與構成靜 止的托盤的光碟裝設部的基壁之間，主要形成空氣流。空 氣流通過的排放口設置於從構成托盤的光碟裝設部的基壁 立起，與光碟的外側相對應的側壁上，故在托盤的光碟裝 設部產生的空氣流有效通過托盤的排放口而排出。可通過 該空氣流，有效地將光碟裝置主體內的熱量排到光碟裝置 主體之外。 按照本發明申請專利範圍第4項所述的發明，在托盤的 光碟裝設部產生的空氣流容易吹到設置在光碟裝置主體的 後側的基板上。當使光碟旋轉時，光碟和托盤接納於光碟 -17- 1264710 裝置主體內。此時3由於在托盤的大致中間部的後側，形 成光碟裝設部的壁上·設置空氣流通過的排放口，例如當 從平面透射光碟裝置時，在托盤的基本中間部的後側，設 置於形成光碟裝設部的壁上的空氣流通用的排放口，與裝 設於托盤的光碟裝設部產生的空氣流通過設置於托盤上的 排放口而排放，容易吹到設置於光碟裝置主體的後側的基 板上。於是，設置於光碟裝置主體的後側的基板的熱量可 有效地通過在托盤的光碟裝設部產生的空氣流奪取。另 外，如果構成這樣的光碟裝置，則容易將設置於基板上的 積體電路的溫度保持在允許範圍內的溫度。於是，可在溫 度具有富裕的狀態，採用設置於基板上的積體電路。 按照本發明申請專利範圍第5項所述的發明，設置於構 成光碟裝置主體的支架上的雙面基板的一個側面和另一側 面容易與在托盤的光碟裝設部產生的空氣流。由於雙面基 板在與構成光碟裝置主體的支架的基板離開的狀態設置於 支架，故從雙面基板的一個側面產生的熱量，與從雙面基 板的另一側面產生的熱量排放到光碟裝置內的空氣中。另 外，雙面基板的一個側面產生的熱量，與雙面基板的另一 側面產生的熱量由伴隨光碟的旋轉而產生的空氣流而奪 取。另外，奪取雙面基板的熱量的空氣流從設置於構成光 碟裝置主體的支架上的排出□，排到光碟裝置主體的外 側。於是，可通過在托盤的光碟裝設部產生的空氣流，有 效地冷卻設置於構成光碟裝置主體的支架的雙面基板的熱 量。 按照本發明申請專利範圍第6項所述的發明，從托盤的 -18- 1264710 光碟裝設部產生的空氣流容易在光碟裝置主體的內部運 動。由於在設置於形成托盤的光碟裝設部的壁上的空氣流 通用的排放口，與設置於光碟裝置主體上的空氣流通用的 排出口之間，設置使空氣流在光碟裝置主體的內部運動的 導向壁，故從托盤的光碟裝設部產生的空氣流與導向壁接 觸，容易在光碟裝置主體的內部運動。於是，可避免在光 碟裝置主體的內部，局部地產生高溫的部分，可將光碟裝 置主體內的溫度保持在允許範圍內的溫度。 按照本發明申請專利範圍第7項所述的發明，從托盤的 光碟裝設部產生的空氣流與設置於托盤的導向壁接觸。由 此，使拾取器周邊的空氣流動，從拾取器產生的熱量容易 爲流動的空氣奪取。於是，可避免構成拾取器的雷射二極 體處於異常高溫的狀態，因該高溫，對雷射二極體的性能， 雷射二極體的壽命造成不利影響的情況，由於爲構成拾取 器的雷射二極體，故可射出長期穩定的雷射。 按照本發明申請專利範圍第8項所述的發明，可從構成 光碟裝置主體的支架，與設置於托盤的前側，覆蓋光碟裝 置主體的內部的面板之間的間隙，有效地將空氣吸入到光 碟裝置主體的內部。伴隨設置於光碟裝置內部的光碟的旋 轉，在托盤的光碟裝設部產生空氣流。但是，爲了有效地 從設置於光碟裝置主體上的排出口，將該空氣流排到光碟 裝置主體的外側，在光碟裝置中必須要求可容易使空氣流 入的吸入口。通過因設置於光碟裝置內部的光碟的旋轉而 產生的空氣的運動，光碟裝置主體內的空氣從光碟裝置的 吸入口，向排出口流動。於是，可防止熱量積蓄於光碟裝 -19- 1264710 置內部’可將光碟裝置內的溫度保持在使用允許範圍內的 溫度。 按照本發明申請專利範圍第9項所述的發明，可提供不 必要求風扇等的特別的冷卻裝置，放熱特性優良的筆記本 型電腦用的光碟裝置。最近的筆記本型計算機具有高性能 化，小型化，輕量化，輕薄化的傾向。如果提高電腦的性 能，則從電腦中’產生較多的熱量。由此，在電腦中，必 須某種的冷卻機構。另一方面，在最近的筆記本型電腦中， 要求小型化’輕量化，輕薄化。風扇等的特別的冷卻裝置 等設置於筆記本型電腦中，這會導致筆記本型電腦的大型 化，重量增加。這樣的情況與筆記本型電腦的使用者的要 求相反。但是，如果採用伴隨設置於光碟裝置中的光碟的 旋轉而產生的空氣流，防止光碟裝置內的溫度的提高，則 避免筆記本型電腦的大型化，重量增加。於是，可具有構 成沒有大型化，重量增加，緊湊的，放熱特性優良的光碟

載，或放置光碟3。此外，也可採用下述的光碟裝置7〇， 其中，具有這樣的托盤5，並且具有轉臺2的主軸馬達4 和光拾取器6設置由於光碟裝置主體1的內部。 在該排放口 5e的後部，突設有導向壁7。該導向壁7從 該側壁55b的頂部’設置於基本與該基壁55a基本平行而 延伸設置的頂壁55f的內側。該導向壁7在頂壁55f的內 側，朝向底側立設。另外，該導向壁7作爲基本呈板狀的 肋7而形成。該肋7的高度與相對該基壁5 5 a而立設的各 側壁55b，55c’ 55d的筒度基本相同。該肋7(第2圖）設 置於托盤主體5 u上’以便將通過排放口 5 e獲取的空氣流b 的一部分擴散到光碟裝置主體1的內部。另外，在構成托 -23- 1264710 盤3、第1圖〜第3圖）的托盤主體.5 u的前面，安裝有面 板8。 相對托盤主體5 II和光碟裝置主體1，面板8所在的一側 爲光碟裝置7 0的前側。另外，相對托盤主體5 u和光碟裝 置主體1，基板9所在的一側爲光碟裝置7 0的後側。此外， 在托盤主體5 u中，頂壁5 5 f所在的一側爲頂側，基壁5 5 a 所在的一側爲底側。另外，在托盤主體5 u中，第2圖所示 的平面看的一側爲托盤5的外側，從其反側看到的一側爲 托盤5的內側。另外，在說明書中的“前，’、“後”、 “上”、“下”、“外”、“內”的定義便於對光碟裝置 7 〇進行描述。 在光碟裝置主體1的內部，設置有控製基板9(第1圖 〜第4圖）。在控製基板9的雙面，設置有用於驅動光碟 驅動等的電路。該控製基板9按照至少具有基板主體9 h， 與安裝於該基板主體9h上的各積體電路9a，9b的方式構 成。控製基板9 (第4圖）的一側面9ι構成控製基板9的 頂面9ι，控製基板9的另一側面％構成控製基板9的底面 9j。在控製基板9的頂面上，設置有頂部積體電路9a。 此外，在控製基板9的底面9」，設置有底部積體電路9b。 在光碟裝置主體1的後面側，設置有連接器1 〇。設置於 光碟裝置70上的連接器1〇,與設置於圖中未示出的筆記本 型電腦中的對方側連接器（圖中未示出）以可通電的方式 連接。由此，將從筆記本型電腦發出的各命令傳遞給光碟 裝置70。 此外，在光碟裝置主體1的後面側，設置有使光碟裝置 -24- 1264710 主體1內的空氣通過的3基本呈矩形狀的各排出口 U · } 2。 如第3圖和第4圖所示，頂部排出□ 1 1設置於光碟裝置主 體1的後面側，按照與控製基板9的頂部積體電路9 a基本 相同的高度定位。還有，底部排出口 1 2設置於光碟裝置主 體1的後面側，按照與控製基板9的底部積體電路9 b基本 相同的高度定位。 如桌1圖〜桌4圖所不，光碟裝置70按照至少包括光 碟裝置主體1，與可相對光碟裝置主體1，實現開閉的托盤 5的方式構成。在托盤5中，設置有具有光碟3(第2圖〜 第4圖）的光碟裝設部50 (第1圖）。光碟位於形成光碟 裝設部50的合成樹脂製的壁55的內側。構成伴隨光碟3 (第2圖）的旋轉，在光碟裝設部50中，產生空氣流A， B的光碟裝置7 0。 在構成合成樹脂製的托盤主體5 u的壁5 5上，設置有從 壁55的內側，朝向壁55的外側，設置有使空氣流A，B 通過的空氣流排放口 5 e。此外，在構成光碟裝置主體1的 金屬製支架1 a的後側，設置有排出光碟裝置主體1內的溫 度較高的空氣的空氣流排出口 1 1，1 2。 如果通過這樣的結構，構成光碟裝置7 0，則避免在光碟 裝置70的內部蓄積熱量的情況，容易將光碟裝置70內的 熱量排到光碟裝置70的外部。伴隨設置於光碟裝置70的 內部的光碟3的旋轉，空氣流A ’ B產生於托盤5的光碟裝 設部5 0中。該空氣流A，B從開設於托盤5的光碟裝設部 5〇的壁5 5中的空氣流排放口 5 e，朝向設置於光碟裝置主 體1的後側的頂側的空氣流排出口 Π流動。另外，一部分 -25- 1264710 的空氣流C，D從開設於托盤5的光碟裝設部5 0的壁5 5 中的空氣流排放口 5 e，朝向開設於光碟裝置主體1的後側 的底側的空氣流排出口 1 2流動。 於是’光碟裝置主體1的內部的熱量通過空氣流B，C， D，從光碟裝置主體1的後側的空氣流排出口 1 1，1 2，朝 向光碟裝置主體丨的外部排出。由此，避免在光碟裝置70 上’設置冷卻用風扇等的特別的冷卻器的情況，將加熱特 性優良的緊湊的薄型的光碟裝置7 〇提供給光碟裝置7 〇的 使用者’將光碟裝置7 〇提供給將其裝配於PC等的設備的 廠商等。 開設於托盤5 (第1圖，第2圖）中的空氣流排放口 5 e 設置於從托盤5的前側，朝向托盤5的後側，形成空氣流B (第2圖’第4圖）的位置。對應於空氣排氣口 5 e，開設 於構成光碟裝置主體1的支架1 a上的空氣流排出口丨丨設 置於光碟裝置主體1的後側。空氣流排出口 1 1設置於構成 光碟裝置主體1的後部側壁1 c上。 如果通過這樣的結構，構成光碟裝置70，則伴隨光碟3 的旋轉，在托盤5的光碟裝設部50產生的空氣流A，B穿 過開設於形成托盤5的光碟裝設部5 0的壁5 5中的空氣流 排放口 5 e，朝向托盤5的後側流動。此時，托盤5處於接 納於構成光碟裝置主體1的支架1 a的接納室1 r的內部。 產生於形成托盤5的光碟裝設部5 0的內側的空氣流A， B穿過開設於構成托盤主體5 u的壁5 5中的空氣流排放口 5e而排出，排出到形成托盤5的光碟裝設部50的壁55的 外側。另外，該空氣流B (第2圖，第4圖）主要從開設 - 26- 1264710 於構成光碟裝置主體1的支架1 a的後部側部1 c中的空氣 流排出口 1 1排出。於是，將光碟裝置主體1的內部的熱量 快速地排到光碟裝置主體1的外部。 此外’有下述的擔心，即，當伴隨光碟3 (第2圖）的 旋轉而產生的空氣流A，B爲紊流時，通過形成紊流的空 氣流，在光碟3，光碟裝置7 0中，產生較小的振動，或從 光碟3，光碟裝置7〇，產生低噪音。但是，在形成托盤5 的光碟裝設部5 0的壁5 5上，設置有使空氣流A，B通過的 空氣流排放口 5e，空氣流b從形成托盤5的光碟裝設部5〇 的壁5 5的內側，排出到壁5 5的外側，由此，對空氣流A， B進行整流處理。於是，避免當將光碟3設置於光碟裝置 70中，使光碟3旋轉時，從光碟3，光碟裝置70，產生較 大的振動，較大的噪音，降低光碟裝置70的振動，噪音。 構成托盤主體5u (第1圖）的合成樹脂製的壁55按照 具有基本呈平板狀的基壁55a (第1圖，第2圖），彎曲狀 的各側壁55b，55c，55d (第1圖）和基本平板狀的各頂壁 55f的方式構成，該基壁55a與光碟3(第2圖〜第4圖） 的平面部3 a相對應，該各側壁5 5 b，5 5 c，5 5 d從基壁5 5 a， 朝向斜上側，相對基壁5 5 a，以鈍角上抬，與光碟3的外周 部3b相對應，該各頂壁55f從各側壁55b，55c，5 5d的頂 端’相對基壁5 5 a，基本平行地延伸設置。該空氣流排放口 5 e設置於構成托盤主體5u (第1圖）的合成樹脂製的側壁 55b ° 如果通過這樣的結構，構成光碟裝置7 0，則產生於托盤 5的光碟裝設部5 0的空氣流A，B通過開設於托盤5的光 -27- 1264710 碟裝設部的壁5 5中的空氣流排放口 5 e而排出，容易從形 成托盤5的光碟裝設部5 0的壁5 5的內側，排到外側。 在所旋轉的光碟3 (第2圖〜第4圖）的平面部3 a，與 構成靜止的托盤5的光碟裝設部5 0的基壁5 5 a的間隙，以 及與構成支架1 a的頂側的蓋1 p之間的間隙中，主要形成 i _流A，B。使空氣流A，B通過的排放口 5 e設置於基本 彎曲狀的側壁5 5 b，該側壁5 5 b從構成托盤5的光碟裝設部 5 0的基本平板狀的基壁5 5 a ’朝向傾斜頂側，相對基壁5 5 a， 以鈍角上抬，與光碟3的外周部3b相對應，由此，產生於 托盤5的光碟裝設部5 0的空氣流A，B有效地通過托盤5 的空氣流排放口 5 e而排放。有效地通過該空氣流a，B， 將光碟裝置主體1內的熱量排到光碟裝置主體1之外。 讀取光碟3 (第1圖〜第3圖）的資料的光拾取器6設 置於托盤5上。另外，對光碟3，光拾取器6等進行電控製 的基板（第1圖〜第4圖）設置於光碟裝置主體1的後側。 對應於基板9，在位於托盤5 (第1圖，第2圖）的基本中 間邰5 m的後側的側壁5 5 b上，設置有該空氣流排放口 5 e。 如果通過這樣的結構，構成光碟裝置70，則容易將在托; 盤5的光碟裝設部50中產生的空氣流A，B，吹向光碟裝 置主體1的後側的基板9。當光碟3 (第2圖）旋轉時，將 光碟3和托盤5接納於光碟裝置主體1的內部。此時，在 托盤5的基本中間部5 m的後側的，形成光碟裝設部5 0的 側壁5 5 b上，設置有使空氣流A，B通過的空氣流排放口 5 e。 於是，例如當對光碟裝置7 0的內部進行平面透視時，空氣 流通用的空氣流排放口 5 e，與基板9重合，該空氣流排放 -28- 1264710 口 5 e設置於托盤5的基本中間部5 m的後側的，形成光碟 裝設部5 0的側壁5 5 b上，該基板9設置於光碟裝置主體1 的後側。 由此，在托盤5的光碟裝設部5 0中產生的空氣流a，B 通過開設於托盤5中的空氣排放口 5 e而排出，容易將其吹 向設置光碟裝置主體1的後側的基板9(第2圖，第4圖）。 於是，通過在托盤5的光碟裝設部5 0中產生的空氣流a， B，有效地奪去設置於光碟裝置主體1的後側的基板9的熱 量。另外，如果像這樣，構成光碟裝置7 0，則容易將設置 於基板9上的，用作雷射二極體驅動用的電路的各積體電 路9 a ’ 9 b的溫度保持在允許範圍內的溫度。於是，設置於 基板9上的積體電路9a，9b可在溫度具有富裕的狀態使 用。 對光碟3，光拾取器6等進行電控製的基板9設置於構 成光碟裝置主體1的支架la的內部。在基板9的基板主體 9h的內外，形成設置各積體電路9a，9b等的各種電氣/電 子部件9a，9b等的雙面基板9。雙面基板9按照從構成光 碟裝置主體1的支架丨a的底壁1 b，朝向頂側離開的狀態， 設置支架1 a上。雙面基板9的底側的積體電路9b在與構 成光碟裝置主體1的支架1 a的底壁1 b離開，例如浮起的 狀態’位於支架1 a的接納室1 r的內部。設置於構成光碟 裝置主體1 (第4圖）的支架1 a的空氣流排出口 1 1，1 2形 成於容易使雙面基板9的頂面9ι的空氣流B，與雙面基板 9的底面9」的空氣流D排出到光碟裝置主體1的外側的位 置。 -29- 1264710 如果通過這樣的結構，構成光碟裝置70，則設置於構成 光碟裝置主體1的支架1 a上的雙面基板9的頂面9ι和底 面9」容易與托盤5的光碟裝設部5 0產生的空氣流b , D接 觸。由於雙面基板9在從構成光碟裝置主體1的支架la的 底壁1 b，向上側離開的狀態，設置支架1 a上，從雙面基板 9的頂面9ι發出的熱量，與從雙面基板9的底面9j發出的 熱量排到光碟裝置70內的空氣中。另外，由光碟3的旋轉 虜生的空氣流，奪取從雙面基板9的頂面發出的熱羹， 與從雙面基板的底面9j發出的熱量。另外，奪取了雙面基 板9的熱量的空氣流B，D從設置於構成光碟裝置主體1 的支架1 a上的空氣流排出口丨丨，1 2，排到光碟裝置主體1 的外側。於是，通過由托盤5的光碟裝設部50產生的空氣 流B ’ D，有效快速地對設置於構成光碟裝置主體1的支架 1 a上的雙面基板9的熱量進行冷卻。 在第1圖〜第4圖所示的光碟裝置70中，設置有多個 空氣流排出口 1 1，1 2，但是，還可採用例如空氣流排出口 1 1，1 2按照同時用作連接器口的方式設置光碟裝置。另外， 空氣流C’ D在光碟裝置主體ι(第2圖）的接納室ir 內部的合成樹脂製的肋7 (第1圖，第2圖）設置於空氣流 排出口 5 e，與頂部排出口 11之間。該肋7 (第1圖）設置 於從構成托盤主體5 u的側壁5 5 b的頂部，按照與基壁5 5 a 基本平行的方式延伸的頂壁55f的內側。肋7在頂壁55f 的內側’朝向底側立設。此外，該肋（第2圖，第4圖） 相對從托盤5的前側，朝向托盤5的後側而移動的空氣流 B，沿基本垂直的方向延伸。另外，合成樹脂製的肋（第丄 -30- 1264710 圖〜第4圖）與構成托盤5的合成樹脂製的托盤主體5 u形 成一體。 如果通過迨樣的結構’構成光碟裝置7 0，從托盤5的光 碟裝設部50產生的空氣流A，B (第2圖）容易在光碟裝 置主體1的內部運動。由於在設置於形成托盤5的光碟裝 設部的壁5 5上的空氣流通用的排放口 5 e，與設置於光碟裝 置主體1上的空氣流通用的頂部排出口 1 1之間，設置肋7， 該肋7使空氣流C，D在光碟裝置主體1的內部運動，故從 托盤5的光碟裝設部50產生的空氣流A，B與肋7接觸， 谷易在光碟裝置主體1的內部運動，於是’避免在光碟裝 置主體1的內部，局部地產生高溫的部分的情況，將光碟 裝置主體1內的溫度保持在允許範圍內的溫度。 可讀取光碟3 (第2圖）的資料的光拾取器6 (第1圖， 第2圖）設置於托盤5的內側。另外，使光拾取器6的周 邊的空氣流動的肋7設置於托盤5的內側。 如果通過這樣的結構，構成光碟裝置70，則從托盤5的 光碟裝設部5 0產生的空氣流A與設置於托盤5上的肋7接 觸，形成空氣流C，繞到托盤5的內側。與肋7接觸的空 氣流C繞到構成托盤主體5 u的基壁5 5 a的底側。在托盤5 上，設置該肋7，由此，位於光拾取器6的空氣流C，D在 光碟裝置主體1的接納室1 r的內部。 由此，光拾取器6的周邊的空氣流動，容易通過流動的 空氣，奪取從光拾取器6的雷射二極體產生的熱量。於是， 避免構成光拾取器6的雷射二極體處於異常高溫的狀態， 由於該高溫，對雷射二極體的性能，雷射二極體的壽命， -31 - 1264710 記錄於光碟3上的資料的品質等造成不利影響的 從構成光拾取器6的雷射二極體，射出長時間地 穩定的雷射。 另外，由於在托盤5的內側，產生空氣流C ’ 動的空氣容易奪取從旋轉驅動光碟3 (第3圖，_ 主軸馬達4產生的熱量。另外，由於在托盤5的 生空氣流C，D，故容易通過流動的空氣，奪取從 達4形成一體，並且對主軸馬達4進行控製的該 的積體電路產生的熱量等。另外，由於在托盤5 產生空氣流C，D，故從驅動光拾取器6的拾取器 運送馬達（圖中未示出）產生的熱量也容易爲流 所奪取。於是，容易避免該主軸馬達4，該電路3 體電路，該運送馬達等曝露於異常高溫的狀態下 覆蓋光碟裝置主體1(第1圖〜第3圖）的內音丨 設置於托盤5的前側。其中，在相對光碟裝置主1

0中，產生空氣流a，B。但是， 爲了有效地將該空氣流A，B從設置於光碟裝置主體1上的 各空氣流排出口 Π，1 2，排到光碟裝置主體1的外側，空 氣可容易流入的各吸入口 13，14，15在光碟裝置70中， 是必要的。 由於可將空氣有效地吸入到光碟裝置7 0的內部的吸入 口 1 3，1 4，1 5設置於光碟裝置7 0的前側，故伴隨因設置 於光碟裝置70內部的光碟3旋轉而產生的空氣的運動，光 碟裝置主體1內部的空氣從光碟裝置70的吸入口 13, 14, 1 5，向空氣流排出口 1 1，1 2流動。於是，防止在光碟裝置 70的內部，充滿熱量，將光碟裝置70內的溫度保持使用允 許範圍內的溫度。像這樣，通過自然冷卻，對設置於該光 碟裝置70中的各積體電路，雷射二極體，各馬達等的發熱 體進行冷卻。 具有托盤5的光碟裝置主體1(第1圖〜第4圖）可設 置於較薄的圖中未示出的筆記本型個人電腦中。光碟裝置 70形成筆記本型個人電腦專用的光碟裝置70。 如果像這樣構成，不必要求風扇等的，消耗電力的特別 的冷卻裝置，將放熱特性優良的筆記本型個人電腦用的光 碟裝置70提供給電腦裝配廠商等。最近的筆記本型個人計 算機具有高性能化，小型化，輕量化，輕薄化的傾向。如 果使個人電腦高性能化，則從設置於個人電腦中的控製基 板9的積體電路9a，9b，光拾取器6的雷射二極體等，產 生大量的熱量。由此，在個人電腦中，必須要求採用某種 冷卻機構。另一方面，筆記本型個人電腦的設計者，使用 -33- 1264710 者等要求最近的筆記本型個人電腦小型化，輕量化，輕薄 化。風扇等的，消耗電力的特別的冷卻裝置設置於筆記本 型個人電腦中，這意味著導致筆記本型個人電腦的大型 化’重量增加，這樣的情況與筆記本型個人電腦的設計者， 使用者的要求相反。 但是，如果採用伴隨設置於光碟裝置70的內部的光碟3 的旋轉而產生的空氣流A，B，C，D，E，F，G，防止光碟 裝置7 0內部的溫度增加，則避免筆記本型個人電腦的大型 化’重量增加。於是，沒有大型化，重量增加的情況，以 較小的體積，構成具有構成放熱特性優良的光碟裝置7 0的 筆記本型個人電腦。另外，還避免筆記本型個人電腦的耗 電量的增加。

CD player, DVD player A player that uses both CD and DVD discs. Follow, for example, a PC with a note, A desktop PC or the like is used in an assembled manner. The PC is an abbreviation for Personal Computer. In addition, On the main body of the player that constitutes the player, A tray with a loadable tray is provided. The tray is in the specified position, As a CD that can be installed, Formed in the form of . Such a tray is placed in front of the main body of the player. More specifically, In front of the player body that makes up the player, Set the tray, The tray can mount the optical disc in the optical disc device. A tray for ejecting discs from a disc. In addition, In the middle of the main body of the disc device, Set the turntable with the drive. In addition, A pickup for performing an operation of reading a signal from the optical disk is mounted on the main body of the optical disk device. In addition, At the back of the disc device, Set up electricity On the back side of the disc device, Set with connection terminals, This connector can be connected to the main body of the computer. In a write-on CD, Or a recordable optical disc such as a rewritable CD, When there is information, etc. The larger output 値 laser is illuminated from the laser of the pickup onto the disc. Record data on the disc. Recording data on a disc from the laser diode of the pickup, A laser that emits a large output 値. In order to get a laser from the pickup, Output a large output laser, The laser diode must require more current. The current flowing through the laser two flows from the integrated circuit mounted on the substrate main body constituting the circuit, thereby When recording data on a disc, A large amount of current flows through the integrated circuits constituting the circuit. Because it is constructed like this, Record data or two on the disc; , This type of brain setting DVD has an internal disc setting path. When the pole is recorded, The polar body of 値. road, Time, 1264710 From the laser diode, With the integrated circuit, Produce more heat. The laser diode and integrated circuit form an electrical/electronic component that generates more heat. Also from electrical and electronic components other than laser diodes and integrated circuits, Produce heat. Laser diode, The amount of heat generated by the integrated circuit greatly exceeds the heat generated from the electronic components other than the laser diode and the integrated circuit. In addition, When recording data on a disc, Relative to the main body of the optical disc device, The tray is running in a closed state, thus, The heat generated from the laser diode ' accumulated in the integrated circuit or the like is accumulated inside the holder constituting the main body of the optical disk device. When from a laser diode, When emitting light, The oscillation of the laser of the laser diode is wavelength dependent on temperature. thus, If the temperature of the laser diode changes greatly, The wavelength of the laser emitted from the laser diode also changes. If the heat emitted by the laser diode itself is passed, Saving the laser diode, Then the wavelength of the laser emitted from the laser diode changes. If this happens, Not from the laser diode, A laser that emits a constant wavelength. As a temperature rise of the heating element that prevents the pickup or the like, Prevent over temperature rise, a device that deteriorates the characteristics of a heating element, Includes the following disc drive, In the disc drive, Set a propeller on the same axis as the axis of rotation of the spindle motor, Or a fan, The wind is generated by the rotation of the spindle motor, The wind is located at the picker, motor, a heating element such as a circuit, These heating elements are cooled (for example, refer to Japanese Patent Laid-Open Publication No. 2002-2524 3, No. 1, 3 pages, number 6, 11, 14, 15 maps, etc.). but, In the past optical disc device, Since it is easy to accumulate heat in the inside of the bracket constituting the main body of the optical disc device, It is difficult to carry out the laser diode, The heat release of the integrated circuit. If a laser diode is formed, The 1264710 integrated circuit has a heat-dissipating structure, There are laser diodes, Integrated circuit, There is a danger of heat accumulation due to heat or the like. As mentioned above, Due to when from the laser diode, When shooting a laser, The oscillation wavelength of the laser of the diode depends on the temperature. Therefore, if the temperature of the laser changes greatly, Then the wave of the laser emitted from the laser diode. If the heat is emitted by the laser diode itself, The temperature of the laser is abnormally high, Then the wavelength of the laser emitted from the laser diode is such that Not from a laser diode, Shoot a constant laser. In the state where the laser diode is in an abnormally high temperature state, In the case of optical disc loading, With a pair of laser diodes, In the case where the optical disc is adversely affected, for example, when the laser diode is in an abnormally high temperature state, the data is recorded on the disc. For the performance of the laser diode, The life of the laser, The quality of the data recorded on the disc is such that it is larger, If the laser diode is in an abnormally high temperature state, Record data on a disc, Have the following dangers, which is, The life of the emitter diode is shortened, In addition, The performance of the laser diode is not satisfied with the reliability of the disc. If specifically described, It is a CD-R, etc., which is a CD-ROM: Information, The current of a larger current 流 flows through the circuit used by the control circuit, A laser diode connected to the integrated circuit. then, The product is heated with the laser diode. In the case of such a state, The laser generates heat from the heat generated by the laser diode itself. In addition, With the heat generated from the integrated circuit, etc., The temperature of the laser diode is increased by one liter. Because the integrated circuit is hot, Then, the temperature of the periphery of the optical pickup itself changes, and the length of the diode also changes. The wavelength of the record is dangerous. , In the light diode effect. Conditions form a mine, Remember Write integrated body circuit due to the situation, Step up. In 1264710, the state of the laser diode is abnormally high, Recording data on a disc, Has a lifetime for the laser diode, The performance of the laser diode, The quality of the material recorded on the disc poses a risk of adverse effects. In order to prevent heat from accumulating inside the optical disc device, Also in the disc device, Set the fan for cooling, Avoid high temperatures in the disc unit. Such a way is, for example, for a desktop PC (not shown), Form an effective cooling method. The desktop computer is a desktop computer. a computer that you can use on your desk. but, For types that are not easy to handle. Due to the relative desktop PC, Notebook PC (not shown) requires lightweight, Light and thin, Therefore, it has a structure in which an optical disk device in which a narrow type driver is provided is formed.

Relative to the PC body, The display is folded, thus, Form a thinner size. The P C of the notebook type is a size of approximately A4 when viewed from a plane. Or a widely used personal computer with the following dimensions, Also known as a book PC. like this, What is important is that the notebook PC is compact overall. It can be easily transported. Since the optical disc device for a notebook type PC is thin, Therefore, people think that from the aspect of insufficient installation space of the optical disc device, In a compact disc device for a notebook PC, It is unreasonable to provide a cooling fan that prevents the temperature of the optical disk device from rising. In order to provide a cooling fan for preventing the temperature rise of the optical disk device in the optical disk device for a notebook PC, It is necessary to expand the installation space of the components of the optical disc device. In a disc device for a notebook PC, Enlarging the installation space of the components leads to an increase in the overall size of the notebook PC. In addition, In such a notebook type P C, The weight is increased.

The inner sound of the lower cover optical device main body 1 (Figs. 1 to 3) is disposed on the front side of the tray 5. Among them, in the case of the relative optical disk device main 1 (Fig. 3), when the tray 5 is closed, the following is formed. The opening portion 1 u of the bracket 1 a of the structure disc device main body 1 and the gap panel 13 are provided between the brackets 8 and are provided with respective gaps 1 3 (Fig. 3) and 14 (15th. These gaps 13 (Fig. 3), 14 (Fig. 2), 15 flows into the main body of the disc device When the optical disk device 70 is configured by such a configuration, the opening portion 1U of the holder 1a of the optical disk device main body 1 and the panel 8 provided on the holder side covering the inside of the optical disk device main body 1 are 1 3 , 1 4, 1 5, effectively sucking air into the optical disc device main body 1 with the case of the optical disc 3 installed inside the optical disc device 70 (Fig. 2), the inside of the long-term D, so flow; 4) The case is produced by the inner side of the spindle horse circuit board and the moving air S plate of the main body portion. The panel 8 i 1 of the 5 (the second, constituting the :2 diagram on the optical disk 5) is placed inside the respective gaps constituting the disk 5. Rotation, - 32-1264710 In the disc mounting 邰50 of the tray 5, air flows a, B are generated. However, in order to effectively discharge the air flow A, B from the respective air flow discharge ports Π, 12 provided on the optical disk device main body 1, to the outside of the optical disk device main body 1, air can easily flow into the respective suction ports 13, 14,15 is necessary in the optical disc device 70. Since the suction port 13 3, 14 , 15 which can effectively suck the air into the inside of the optical disk device 70 is disposed on the front side of the optical disk device 70, it is caused by the rotation of the optical disk 3 provided inside the optical disk device 70. The movement of the air, the air inside the main body 1 of the optical disc device flows from the suction ports 13, 14, 15 of the optical disc device 70 to the air flow discharge ports 1, 1, 2 2 . Thus, the inside of the optical disc device 70 is prevented from being filled with heat, and the temperature in the optical disc device 70 is maintained at a temperature within the allowable range. In this way, the heat generating bodies of the respective integrated circuits provided in the optical disk device 70, the laser diodes, and the motors are cooled by natural cooling. The optical disk device main body 1 (Figs. 1 to 4) having the tray 5 can be placed in a thin notebook computer not shown in the drawings. The optical disk device 70 forms a compact disk device 70 for a notebook type personal computer. In this way, it is not necessary to require a special cooling device that consumes electric power such as a fan, and the optical disk device 70 for a notebook type personal computer having excellent heat radiation characteristics is supplied to a computer assembler or the like. Recently, notebook personal computers have a tendency to be high-performance, compact, lightweight, and thin. When the performance of the personal computer is improved, a large amount of heat is generated from the integrated circuits 9a, 9b of the control board 9 provided in the personal computer, the laser diode of the optical pickup 6, and the like. Therefore, in a personal computer, a certain cooling mechanism must be required. On the other hand, designers of notebook personal computers, such as -33-1264710, require the recent notebook PCs to be miniaturized, lightweight, and thin. A special cooling device such as a fan that consumes power is installed in a notebook type personal computer, which means that the size of the notebook type personal computer is increased, and the situation is increased with the designer of the notebook type personal computer. in contrast. However, if the air flow A, B, C, D, E, F, G generated by the rotation of the optical disc 3 provided inside the optical disc device 70 is used to prevent an increase in the temperature inside the optical disc device 70, the notebook type is avoided. The size of the personal computer has increased in weight. Therefore, in the case of no increase in size and weight increase, a notebook type personal computer having an optical disk device 70 which is excellent in heat radiation characteristics is formed in a small volume. In addition, the power consumption of notebook PCs is also prevented. As such, the optical disk device of the present invention is mainly suitable for a notebook computer. The optical disk device 70 is of a type in which the optical disk device main body 1 is attached and detached with respect to a notebook type personal computer. That is, the optical disk device 70 is detachably attached to the notebook computer. Further, the optical disk device 70 is configured to cool the optical pickup 6 with respect to the substrate 9 having the circuit provided inside the optical disk drive. On the side wall 5 5 b of the optical disk mounting portion 50 on which the optical disc 3 is disposed, an air flow discharge port 5 e is provided, and in the rear side wall of the bracket 1 a, an air flow discharge port 1 1, U is opened, and is discharged. Between the port 5 e and the discharge port 1 1,1 2, a substrate 9 having a circuit is provided, and the air flow generated by the rotation of the optical disk 3 is received into the inside of the bracket 1 a through the discharge port 5 e of the tray 5 The air flow passes through the substrate 9 or the like having the circuit, and the air flows through the discharge port 111, 1 2, and the warmed condition is discharged to the outside of the optical disk device main body 1, without using a fan (not shown in Fig. 34-126470) A special cooling device that cools the substrate 9 or the like having the circuit. According to this configuration, the optical disk device 70 described below is provided, and the inside of the optical disk device main body 1 can be cooled without providing a special cooling device such as a cooling fan. Next, a description will be given of a state in which the optical disc 3 is set in the optical disc device 70, and the optical disc device 70 operates. The optical disc 3 is set on the turntable 2 by setting the optical disc 3 (Fig. 2) on the inspection unit 2a provided on the turntable 2 (Fig. 1). When the tray 5 is moved from the disc loading/removing position shown in Fig. 1 to the operation position shown in Fig. 2, the spindle motor 4 (Fig. 3, Fig. 4) is rotationally driven in the A direction (Fig. 2). Disc 3. For convenience, the air flow A is indicated by the same reference numeral as the rotation A of the optical disc 3. With the rotation of the optical disc 3, the air flow A also moves in the rotational direction A in the same manner. The air flow A moves in the circumferential direction of the optical disc 3. The air flow A gradually moves along the inner wall faces 5 b, 5 c, 5 d, but since a discharge port 5e through which air passes is formed in the side wall 55b constituting the tray main body 5u, a part of the air flow is shown by an arrow C As a result, the top integrated circuit 9a is cooled, and then passed over the rib 7 and discharged through the top discharge port 1 1 . A portion of the air flow discharged from the discharge port 5 e forms a flow of air diffused through the ribs 7. The air flow diffused by the ribs 7 forms an air flow from the vicinity of the rib 7 toward the intermediate portion 5 m on the inner side of the disk 5 as indicated by an arrow C. This air flow is blown toward the pickup 6. A part of the air flow blown to the pickup 6 is provided in the vicinity of the bottom integrated circuit 9b provided on the bottom surface 9j (fourth diagram) of the control board 9 as indicated by an arrow D (Fig. 2, Fig. 4). It is discharged from the bottom discharge port 12 provided to the holder 1a. In the optical disk device 70 shown in the first to fourth figures, the air flow generated by the rotation of the optical disk 3 is caused to flow from the rear side of the optical disk device main body 1 to the outside. The operation of taking air into the optical disc device main body 1 is performed on the front side of the optical disc device 7 as indicated by an arrow E (Fig. 3), F (Fig. 2), and G. The external air is mainly taken from the bottom gap 丨3 of the front panel 8 as shown by the arrow E (Fig. 3) to the inside of the optical disc device 7. Further, the external air is taken into the inside of the optical disk device 70 from the gaps 14 and 15 on both sides of the front panel 8 as indicated by an arrow F (Fig. 2) or an arrow G.
