200301458 玖、發明說明 【發明所屬之技術領域】 本發明係有關用以將文字資訊及影像資訊顯示於顯示 畫面上之電子顯示裝置，特別地，具有將電子化的文字資 訊及影像資訊予以顯示之可攜式電子書（電子書籍裝置）功能 之電子顯示裝置。 【先前技術】 習知，已揭示稱爲電子書之可攜式電子顯示裝置。該 電子顯示裝置，係將電子資料化之文字資訊或影像資訊顯 示於顯示畫面上，爲了能夠攜帶，使用者能以讀書的感覺 來閱覽文字資訊或影像資訊。進而，爲了能只變更讀出之 電子資料，即可進行不同內容之顯示，而藉由一個電子顯 示裝置，即可閱覽複數個內容。 又，習知亦有模仿書籍的形狀而成之2畫面顯示之電 子書，例如，在日本專利特開平1 1-276466號公報，已揭示 有能進行2畫面顯示之電子書。圖14係表示習知之電子書 外觀之一例之圖。在該特開平1 1-276466號公報中所揭示之 2個顯示畫面102a、102b以鉸鏈部104連接而成之電子書（ 電子顯示裝置）1〇1，係由翻頁開關113、114、模式設定開 關115、書籤設定/解除開關116、以及只依序顯示附加有書 籤之書籤頁和索引頁之書籤/索引傳送開關117等，只配置 電子書的動作所需之最小限度之操作開關而成者。藉此， 實現提升電子書之操作性及小型化。 200301458 又，在特開2001-175191號公報，係揭示有能進行2畫 面顯示之單手支持型顯示裝置。揭示於該特開2001-175191 號公報之單手支持型顯示裝置，係以左右2個顯示面板形 成展開狀態的方式連接，以展開之旋轉軸爲中心，將左右2 個顯示面板設置成能在約110°〜170°的範圍內之任意角度固 定。藉此，使用者能僅以單手來穩定保持該單手支持型顯 示裝置全體。 然而，例如在特開平11-276466號公報所揭示之電子書 ，如圖14所示，在左右兩畫面下方並排配置操作開關。在 以單手保持該電子書之情況，由於左右重量的平衡，大多 係以從下方把持左右2個顯示面板的連接部的方式來保持 電子書，在以單手保持該電子書的狀態下，用於保持的手 無法對操作開關進行操作。 又，特別地，翻頁開關係電子書使用最頻繁的開關。 對於翻頁動作，存在有「往次頁前進的操作」及「返回前 頁的操作」之具有對稱性的2個動作，對應各個動作，大 多配置2個翻頁開關。又，爲使該翻頁動作的對稱性更明 確，如圖14所示般，2個翻頁開關，係傾向於以左右2個 顯示面板的連接部（鉸鏈部）附近爲基準，而配置於遠離2個 顯示面板的連接部之左右對稱的位置。因此，特別地，無 法以保持有電子書的單手’來進行最頻繁使用之翻頁開關 的操作。 又，有關揭示於特開2001-175191號公報之單手支持型 顯示裝置，雖能以單手來保持該單手支持型顯示裝置，惟 2ϋϋ301458 其並未揭示有關操作開關的配置，因此，其並未揭示僅以 保持用的單手來進行操作。如以上所述，在習知技術’雖 能以單手來保持電子顯示裝置，惟並無法以保持有電子顯 示裝置的單手來進行操作。 【發明內容】 爲解決上述問題，本發明之目的係提供能僅以單手來 進行保持及操作之電子顯示裝置，特別地，能僅以單手來

進而，本發明之構成，係在鉸鏈部一方的端部設置帶 狀物。 依此構成，容易將帶狀物插於保持有電子顯示裝置之 單手的指頭，即使萬一離開保持的單手，亦能防止電子顯 示裝置的掉落。 進而，本發明之構成，具有內容儲存機構插入部，內 容儲存機構能將事先記憶在前述顯示畫面顯示的內容插入 ，且從前述內容儲存機構讀出前述內容並予以顯示。 依此構成，本發明之電子顯示裝置，能作爲從可攜式 記憶媒體等之內容儲存機讀出內容之電子書來使用。 【實施方式】 以下，一面參照圖面，一面就本發明之電子顯示裝置 之實施形態加以說明。圖1係本發明之電子顯示裝置之展 開狀態之外觀圖。圖1所示之電子顯示裝置（電子書）1具有 :分別嵌入有顯示畫面2a、2b的2個構件3a、3b、鉸鏈部 4、旋動開關5、操作開關組6、內容儲存機構插入部7、嵌 合部8a、8b。 具有對面之一方的顯示畫面（在圖1爲左側的顯示畫面 )2a的構件3a與具有另一方的顯示畫面（在圖1爲右側的顯 示畫面）2b的右側構件3b，係以中央的鉸鏈部4連結，以該 鉸鏈部4爲基軸，而形成以展開而能往兩方向（左右）開閉的 構成。藉此，可將2個顯示畫面2a、2b設成展開的狀態， 故能設成與一般的書籍、雜誌等同樣的形態。 12 200301458 特別地，針對一般的書籍或漫畫等，由於其係以2畫 面之展開狀態來閱讀爲前提而作成，藉由設置成2畫面顯 示，能忠實地顯現原作。又，在未使用該電子顯示裝置1 的情況，由於能配合2個顯示畫面2a、2b而關閉，並藉由 嵌合部8a、8b來固定該關閉狀態，故能保護顯示畫面2a、 2b。 又，在顯市畫面2a、2b，較佳係例如採用液晶之液晶 顯示機構。藉由採用液晶顯示機構，可使顯示畫面2a、2b 的深度方向（厚度）變薄，因此，能實現電子顯示裝置1的可 攜帶化及小型化。 又，在鉸鏈部4設置旋動開關5，旋動開關5係以鉸鏈 部4的軸（即，2個顯示畫面2a、2b進行開閉時的旋動軸）爲 中心而設置成可旋動。又，旋動開關5，較佳係當以單手保 持鉸鏈部4的端部時，配置於該單手指頭可及的範圍。該 旋動開關5，係具有翻頁功能之操作開關，以鉸鏈部4的軸 爲中心，將旋動開關5從左往右旋動（即，使旋動開關5， 從圖1的下部側面觀之，往順時針（右旋轉）的方向旋動）， 或是從右往左旋動（β卩，使旋動開關5，從圖1的下部側面 觀之，往逆時針（左旋轉）的方向旋動），藉此，能將示畫面 2a、2b的顯示變更爲次頁或前頁的顯示之翻頁操作。又， 在本實施形態，雖將旋動開關5作爲翻頁用的操作開關， 惟亦可設置成具有其他功能的操作開關。有關該旋動開關5 的詳細構成，將於後說明之。 又，按照內容的語言，例如，在日語的文章之情況， 13 200301458 能變更爲縱寫顯示，而在英語的文章時，能變更爲橫寫顯 示。又，即使對弱視者而言，亦可放大顯示，俾容易閱讀 。又，雖未圖示，在電子顯示裝置1亦可設置喇叭等聲音 輸出機構，在顯示文字資訊或影像資訊之際，同時亦可以 聲音來輸出內容。 其次，說明本發明之電子顯示裝置的內部構成。圖2 係表示本發明之電子顯示裝置之內部構成之方塊圖。電子 顯示裝置1具有：中央處理部（CPU) 10、旋動開關信號輸入 部11、操作開關組信號輸入部12、內容讀出部13、顯示部 14之內部構成。 中央處理部10係進行有關該電子顯示裝置1的主要處 理之處理部，例如，係CPU(Central Processing Unit)等之處 理機構。又，旋動開關信號輸入部11係用來將以旋動開關 5的操作所產生的信號供給至中央處理部10的處理部，而 操作開關組信號輸入部12係用來將以操作開關組6的操作 所產生的信號供給至中央處理部10的處理部。又，旋動開 關信號輸入部11係能進行複數個信號之處理，例如，如後 述般，能分別進行有關翻頁的2個信號（即，來自右旋動用 開關55的信號與來自左旋動用開關56的信號）。 內容讀出部13,係用來將由來自旋動開關信號輸入部 11或操作開關組信號輸入部12的信號所指定的內容，從插 入於內容儲存機構插入部7的可攜式記憶媒體（內容儲存機 構）讀出之處理部。又，顯示部14,係用來將藉由內容讀出 部13所讀出且以中央處理部10所處理的內容顯示於顯示 14 20U301458 畫面2a、2b的處理部。 其次，參照圖3A、圖3B、圖3C所示之圖1的部分放 大圖，來說明旋動開關5的詳細構成。圖3A係圖1所示的 旋動開關的部分（圖1的P部分)放大圖，圖3B係圖3A之 a-b之截面圖，圖3C係圖3 A之c-d之截面圖。如上述般’ 該旋動開關5，係以鉸鏈部4的軸爲旋動軸，且以能旋動的 方式設置成具有翻頁功能的操作開關。 在旋動開關5的表面設置凹部51或凸部52。該凹部 51或凸部52，係用來提高旋動開關5的表面摩擦力，爲了 對旋動開關5的施力確實地傳至旋動開關5的旋轉動作， 而將以凹部51或凸部52所形成的槽部設置略平行於旋動 軸53。又，在操作之際，爲了輔助使用者手指的鉤力，例 如，亦可僅設置1個突起部，或是設置規則或不規則排列 之突起部或槽部。又，亦可在旋動開關5的表面配置具有 黏著性的構件，在操作旋動開關5之際，可防止使用者手 指的滑動。 又，旋動開關5，具有沿周方向的既定角度的間隙54 。該間隙54係用來作動將旋動開關5的旋轉動作轉換爲電 氣信號的開關。有關藉由該旋動開關5的旋轉動作來使開 關作動方面，於下述旋動開關5的開關部分的構成一起說 明之。 其次，說明有關旋動開關5的開關部分的構成。圖4 係圖3B之e-f之截面圖。旋動開關5係以旋動軸爲中心， 具有既定角度的間隙54，在該間隙54設置：右旋動用開關 15 200301458 5 5，用來對次頁產生切換顯示之指示信號；及左旋動用開 關56，用來對前頁產生切換顯示之指示信號。 其次，參照圖5A、圖5B、圖6A及圖6B所示之右旋 動用開關55及左旋動用開關56之詳細構成圖’來說明右 旋動用開關55及左旋動用開關56之ΟΝ/OFF狀態。首先’ 說明有關右旋動用開關55。圖5A係圖4之g-h之截面圖’ 表示右旋動用開關之OFF狀態圖。又，圖5B係圖4之g-h 之截面圖，表示右旋動用開關之ON狀態圖。 右旋動用開關55，雖在無來自外部負載的通常狀態下 爲OFF狀態，惟當將開關可動部61上推時，則右旋動用開 關55變爲ON狀態，且對旋動開關信號輸入部送出ON信 號。 當使旋動開關5往順時針（右旋轉）旋動時，間隙54的 位置係與該旋動一起產生變化。又，當使旋動開關5僅以 既定角度（例如15°或25°)旋動時，則形成間隙54的旋動開 關5的邊緣部分（在此稱之爲接觸部）63與開關可動部61接 觸，當作更進一步旋動時，則接觸部63將開關可動部61 上推。如此，藉由將開關可動部61上推，來使右旋動用開 關55變爲ON狀態。又，即使在當右旋動用開關55成爲 ON狀態的情況下，亦可更進一部設置以既定角度（例如5。) 對旋動開關5進行旋動之遊戲的角度，藉此，可形成柔軟 的構造，因而提升操作性。 表示ON狀態的ON信號係供給至旋動開關信號輸入部 11後，再進一步傳送至中央處理部1〇。在中央處理部1〇， 16 20U301458 按照該ON信號，例如判斷爲已進行從左往右之翻頁動作( 在一般文庫或漫畫時之往次頁傳送的動作），讀入對應於次 頁的內容，供給至顯示部14後而顯示於顯示畫面2a、2b。 又，當該〇N信號持續既定時間（例如3秒）以上，且供 給既定時間以上ON信號於中央處理部10時，則中央處理 部10例如可進行每次跳10頁之跳頁處理等其他處理。 另一方面，左旋動用開關56亦具有同樣構造。圖6A 係圖4之i-j之截面圖，表示左旋動開關之OFF狀態圖。又 ，圖6B係圖4之i-j之截面圖，表示左旋動開關之ON狀 態圖。當使旋動開關5往逆時針（左旋轉）旋動既定角度（例 如15°或25°)以上時，則旋動開關5之接觸部64係藉由使 左旋動用開關56的開關可動部62下推，而從右旋動用開 關55供給ON信號至旋動開關信號輸入部11。中央處理部 10，係按照該ON信號，例如判斷爲已進行從右往左之翻頁 動作（在一般文庫或漫畫時之往次頁傳送的動作），讀入對應 於前頁的內容，供給至顯示部14後而顯示於顯示畫面2a、 2b。又，當該ON信號持續既定時間（例如3秒）以上，且供 給既定時間以上ON信號於中央處理部10時，則中央處理 部10例如可進行跳頁處理等其他處理。 又，在旋動開關5、右旋動用開關55、左旋動用開關 56較佳係，例如可裝入彈簧，當無來自外部的負載時，右 旋動用開關55或左旋動用開關56可分別返回OFF狀態的 位置。 又，旋動開關5的構造及機構，並未限於上述電氣連 17 2ϋϋ301458 接之右旋動用開關55及左旋動用開關56，若能隨著旋動開 關5的旋動而產生信號之構成，則任何構成皆可。例如’ 亦可在旋動開關5內設置發出紅外線等之光線的發光元件 ，以及在構件3a內設置受光元件。依此構成，隨著旋動開 關5的旋動，使來自發光元件的光線先從設於旋動開關5 的小孔洩漏後，在以受光元件檢測從小孔洩漏之光線的有 無，藉此，能檢測出旋動開關5的旋動。 依上述實施形態，由於係將以鉸鏈部4的軸爲中心而 旋動之旋動開關5設於鉸鏈部4，並使該旋動開關5旋動， 藉此’能進行翻頁等之既定處理，因此，能以單手來保持 電子顯示裝置1的鉸鏈部4之端部周邊，進而能以該用以 保持的單手來操作旋動開關5，形成能僅以來進行電子顯示 裝置1的保持及操作。 又’圖7係本發明之電子顯示裝置之關閉狀態之外觀 圖。如圖7所示，旋動開關5係露出於電子顯示裝置1的 背面（顯示畫面所存在之面的相反側），在使用電子顯示裝置 1時，可從背面操作旋動開關5。因此，例如，在客滿的電 車中，特別地，在無法將2個顯示畫面2a、2b擴大使用的 情況下，可從背面操作旋動開關5，故非常實用。 又，由於該旋動開關5即使在關閉電子顯示裝置丨的 狀態下亦可旋動，因此，在不使用電子顯示裝置1時，必 須使旋動開關5不動作。在此，例如，可在成對之2個嵌 合部8附近事先設置磁鐵及磁性感測器，藉由該磁鐵及磁 性感測器來檢測出電子顯示裝置之關閉狀態，使旋動開關5 18 200301458 的電氣連接無效，並將旋動開關5鎖住來加以實現。 又，除了以上述鉸鏈部4的軸作爲旋轉軸之旋動開關5 之外，亦可設置各種形狀的操作開關。圖8〜11係表示取代 上述在鉸鏈部4設置旋動開關5的構成，而配置其他構成 的操作開關之一例。 圖8係將本發明之縱旋轉之操作開關配置於鉸鏈部之 一例之構成圖。在圖8，係將具有與鉸鏈部4的軸呈略垂直 方向的軸之旋動開關71設置於鉸鏈部4的構成。又，圖9 係在本發明之鉸鏈部配置按鈕形狀之操作開關之一例之構 成圖。在圖9，係將操作按鈕設置於鉸鏈部的構成。在圖8 及圖9的構成，係取代圖1所示之旋動開關5，而在鉸鏈部 4上配置不同於旋動開關5的形狀之操作開關。 又，圖10係在靠近本發明之鉸鏈部的端部之構件上配 置旋動開關之一例之構成圖。在圖10，於鉸鏈部4的端部 周邊且手指可及的範圍內設置旋動開關73之構成。又，圖 11係在靠近本發明之鉸鏈部的端部之構件上配置按鈕形狀 之操作開關之一例之構成圖。在圖11，於鉸鏈部4的端部 周邊且手指可及的範圍內設置按鈕開關74之構成。在圖10 及圖11，係取代圖1所示之旋動開關5，而在鉸鏈部4的 端部周邊配置操作開關。又，在圖10及圖11，特別地，雖 圖示有當以右手保持鉸鏈部4的下端部時，僅在以該右手 拇指易操作的位置之左側構件3a配置操作開關的構成，惟 亦可將其配置在右側構件3b或兩側構件3a、3b。 以上，依圖8〜11所示之構成，亦能以單手來保持電子 19 200301458 顯示裝置1之鉸鏈部4的端部周邊，進而能以該保持所使 用之單手來進行操作開關之操作，故能僅以單手來進行電 子顯示裝置1之保持及操作。 又，圖12係本發明之電子顯示裝置之展開狀態之外觀 圖，且表示在鉸鏈部中央配置旋動開關之構成圖，且表示 在鉸鏈部中央配置旋動開關之構成圖。在電子顯示裝置1 可更進一步小型化、輕量化，如圖12所示，即使係在電子 顯示裝置1之鉸鏈部中央配置旋動開關5之情況下，該保 持電子顯示裝置1之單手>旨頭亦能到達旋動開關5。 又，圖13表示在本發明之電子顯示裝置設置帶狀物之 狀態之示意圖。在鉸鏈部4的端部，在構造上係最適合設 置帶狀物之處，又，對保持有鉸鏈部4的端部之單手指頭 能容易通過帶狀物81，萬一當電子顯示裝置1離開保持之 單手，亦能防止電子顯示裝置1的掉落。 又，在以上的實施形態，雖已說明具有顯示內容之電 子書功能之電子顯示裝置，惟例如，對於顯示 PDA(Personal Digital Assistaance)等之可攜式終端機、動畫 資訊或使用者所輸入之資訊之電子顯示裝置等，對於能將 電子化的資訊顯示於顯示畫面上之所有電子顯示裝置，皆 可適用於本發明之電子顯示裝置。 【產業上之可利用性】 如以上所述，依本發明，由於將分別具有2個顯示畫 面的2個構件以中央的鉸鏈部連結，具有能以該鉸鏈部爲 20 2ϋϋ301458 基軸而展開之可開閉的構成之2畫面顯示之展開型之電子 顯示裝置（電子書），以保持電子顯示裝置的單手能進行操作 的方式，在鉸鏈部或鉸鏈部的端部周邊設置操作開關，因 此，能僅以單手來進行電子顯示裝置之保持及操作。特別 地，在鉸鏈部，設置以鉸鏈部的軸爲中心之可旋動之旋動 開關，在旋動該旋動開關時，能進行既定之處理，藉此， 能僅以單手來進行電子顯示裝置之保持及操作。 【圖式簡單說明】 (一）圖式部分 圖1係本發明之電子顯示裝置之展開狀態之外觀圖。 圖2係表示本發明之電子顯示裝置之內部構成之方塊 圖。

The display unit 14 is a processing unit for displaying the content read by the content reading unit 13 and processed by the central processing unit 10 on the display 14 20U301458 screens 2a and 2b. Next, a detailed configuration of the rotary switch 5 will be described with reference to an enlarged view of a part of Fig. 1 shown in Figs. 3A, 3B, and 3C. Fig. 3A is an enlarged view of a part of the rotary switch shown in Fig. 1 (part P of Fig. 1), Fig. 3B is a sectional view of a-b of Fig. 3A, and Fig. 3C is a sectional view of c-d of Fig. 3A. As described above, the rotary switch 5 is an operation switch having a page turning function by using the axis of the hinge portion 4 as the rotary axis. A concave portion 51 or a convex portion 52 is provided on the surface of the rotary switch 5. The concave portion 51 or the convex portion 52 is used to increase the surface friction force of the rotary switch 5. In order to reliably transmit the force applied to the rotary switch 5 to the rotary operation of the rotary switch 5, the concave portion 51 or the convex portion is used. The groove formed by 52 is disposed slightly parallel to the rotation axis 53. In addition, in order to assist the hooking force of the user's fingers during operation, for example, only one protrusion may be provided, or protrusions or grooves may be provided in a regular or irregular arrangement. Moreover, an adhesive member may be disposed on the surface of the rotary switch 5, and when the rotary switch 5 is operated, the finger of the user can be prevented from sliding. The rotary switch 5 has a gap 54 having a predetermined angle in the circumferential direction. The gap 54 is used to actuate a switch that converts the rotary motion of the rotary switch 5 into an electric signal. Regarding the operation of the switch by the rotary operation of the rotary switch 5, the configuration of the switch portion of the rotary switch 5 will be described together. Next, the configuration of the switch section of the rotary switch 5 will be described. Fig. 4 is a sectional view of e-f of Fig. 3B. The rotary switch 5 is a gap 54 with a predetermined angle around the rotary axis. The gap 54 is provided with: a right-handed switch 15 200301458 5 5 for generating an instruction signal for switching the display on the next page; and a left-handed switch 56 is used to generate an indication signal for switching the display on the previous page. Next, the ON / OFF states of the right-handed switch 55 and the left-handed switch 56 will be described with reference to detailed configuration diagrams of the right-handed switch 55 and the left-handed switch 56 shown in Figs. 5A, 5B, 6A, and 6B. First, the right-handed switch 55 will be described. Fig. 5A is a sectional view g-h of Fig. 4 'showing the OFF state of the right-handed switch. 5B is a cross-sectional view taken along the line g-h in FIG. 4 and shows the ON state of the right-handed switch. The right-handed switch 55 is in the OFF state in a normal state without an external load, but when the switch movable portion 61 is pushed up, the right-handed switch 55 is turned on, and the right-handed switch signal input portion is turned on. Send ON signal. When the rotary switch 5 is rotated clockwise (to the right), the position of the gap 54 changes together with the rotation. In addition, when the rotary switch 5 is rotated only at a predetermined angle (for example, 15 ° or 25 °), an edge portion (herein referred to as a contact portion) 63 of the rotary switch 5 forming the gap 54 and the switch movable portion When 61 is contacted as if it is further rotated, the contact portion 63 pushes the switch movable portion 61 upward. In this manner, the switch movable portion 61 is pushed up to turn the right-handed switch 55 into an ON state. Further, even when the right-handed turning switch 55 is turned on, it is possible to further set the angle of the game where the turning switch 5 is turned at a predetermined angle (for example, 5.), thereby making it soft. Structure, thereby improving operability. The ON signal indicating the ON state is supplied to the rotary switch signal input section 11 and then further transmitted to the central processing section 10. In the central processing unit 10, 16 20U301458, according to the ON signal, for example, it is judged that the page turning operation from left to right (the operation of transferring to the next page in a general library or comics) has been read, and the corresponding page is read. The content is supplied to the display unit 14 and displayed on the display screens 2a and 2b. When the ON signal lasts for more than a predetermined time (for example, 3 seconds), and the ON signal is supplied to the central processing unit 10 for more than a predetermined time, the central processing unit 10 may perform, for example, page skip processing of 10 pages at a time. deal with. On the other hand, the left-handed switch 56 has the same structure. FIG. 6A is a cross-sectional view taken along the line i-j in FIG. 4 and shows an OFF state diagram of the left-handed switch. FIG. 6B is a cross-sectional view taken along the line i-j in FIG. 4 and shows the ON state of the left-handed switch. When the rotary switch 5 is turned counterclockwise (turning left) by a predetermined angle (for example, 15 ° or 25 °), the contact portion 64 of the rotary switch 5 is the movable portion 62 of the switch of the rotary switch 56 Push down, and the ON signal is supplied to the rotary switch signal input section 11 from the right rotary switch 55. According to the ON signal, the central processing unit 10 judges, for example, that the page turning operation from the right to the left has been performed (the operation of transferring to the next page in the case of a general library or manga), reads the content corresponding to the previous page, and supplies After reaching the display unit 14, it is displayed on the display screens 2a and 2b. When the ON signal lasts for more than a predetermined time (for example, 3 seconds) and the ON signal is supplied to the central processing unit 10 for a predetermined time or longer, the central processing unit 10 may perform other processing such as page skip processing. In addition, the rotary switch 5, the right-handed switch 55, and the left-handed switch 56 are preferably, for example, springs can be installed. When there is no external load, the right-handed switch 55 or the left-handed switch 56 can be returned to OFF, respectively. The position of the state. In addition, the structure and mechanism of the rotary switch 5 are not limited to the right-handed switch 55 and left-handed switch 56 connected to the above electrical connection 17 2 上述 301458. If the signal can be generated as the rotary switch 5 rotates, Any composition is acceptable. For example, a light-emitting element that emits light such as infrared rays may be provided in the rotary switch 5 and a light-receiving element may be provided in the member 3a. According to this structure, as the rotary switch 5 is rotated, the light from the light emitting element is leaked from the small hole provided in the rotary switch 5 first, and then the presence or absence of the light leaking from the small hole is detected by the light receiving element. , Can detect the rotation of the rotary switch 5. According to the above-mentioned embodiment, since the rotary switch 5 which is rotated around the axis of the hinge portion 4 is set at the hinge portion 4 and the rotary switch 5 is rotated, the predetermined page turning and the like can be performed. Therefore, the periphery of the end portion of the hinge portion 4 of the electronic display device 1 can be held with one hand, and the rotary switch 5 can be operated with the one hand for holding, so that the electronic display device 1 can be performed with only one hand.
