200400124 玖、發明說明 【發明所屬之技術領域】 本發明係關於用於熱轉寫印字機之印墨帶卷取用芯及 印墨帶匣者。 又，本發明係關於在熱轉寫印字機上穩固保持印墨帶匣 之印墨帶匣保持機構。 【先前技術】 一般’爲了顯示組入配電盤等的電氣設備的電線的種類 及功能’會在電線上顯示文字及記號。該情況，因爲無法 直接印刷於電線上，因此，在短軟管上預先印上文字及記 號’且將電線插入該軟管內以便顯示。此外，也有於書及 活頁封面的背表紙上黏貼顯示文字及內容的膠帶的情況， 該膠帶也於表面印有標題等的文字。 任一情況，其印字均是藉由熱轉寫印字機來執行者’而 熱轉寫印字機係將軟管及膠帶觸壓於印字輥等的被印字材 的表面，再於其上觸壓印墨帶及印字頭，加熱印字頭使印 墨帶的油墨溶化而將文字及記號熱轉寫於軟管及膠帶上 者。 在將印墨帶匣安裝於印字機前，因爲印墨帶的抽出用芯 及卷取用芯成爲自由狀態，因此，有繞卷於芯上的印墨帶 卷取發生鬆弛的情況，當於該狀態設定印字機時，會有於 文字的印字時產生不良的情況。此外，由於印墨帶爲消耗 品，必須要拆下使用完的印墨帶而裝入新的印墨帶，以往 採用預先將印墨帶收納於匣盒內，而將每一匣盒裝入印字 5 312/發明說明書(補件)/92·05/92104471 200400124 機的匣盒裝入方式。 匣盒方式的優點在於’薄印墨帶的使用容易’且安裝性 良好。相反地，其缺點在於，當使用完印墨帶時’必須全 部廢棄匣盒，除了會污染環境，也有單價高的問題。 相對於匣盒方式，也有僅交換卷取於芯上的印墨帶的芯 卷取裝入方式。此方式與匣盒方式在使用上不同’但是單 價便宜，且廢棄的部分也少，因此，對於環境造成的負擔 也小。 此外，在將如上述的印墨帶匣安裝於熱轉寫印字機上 時，必須要保持印墨帶匣處於無法移動的狀態。爲此，以 往係藉由合成樹脂製構件的彈性來保持對於印墨帶匣的抵 壓或是繫合。 然而，於印墨帶匣上具有使非安裝時內部的印墨帶不致 隨意旋轉的方式，係於匣容器的一部分形成缺口使其繫合 於印墨帶軸而形成止旋者。在具備該種止旋機構的匣盒， 形成藉由安裝於印字機本體，使得設於印字機本體的膠帶 軌道旋轉軸抬起上述止旋機構而解除膠帶軌道的繫合的構 成。根據該方式，因爲於解除時被施加於印墨帶匣的抬起 力大，在以往之合成樹脂構件的保持機構中無法充分地予 以保持。 【發明內容】 本發明用以解消上述問題，其第1目的在於，提供以最 少零件數可消除印墨帶的非安裝時的卷取鬆弛，此外，不 僅可對應於匣盒方式還可對應於芯卷取方式的熱轉寫用印 6 312/發明說明書(補件)/92-05/92104471 200400124 墨帶匣。 此外，本發明之第2目的在於，提供適合於上述熱轉寫 用印墨帶匣的印墨帶卷取用芯。 再者，本發明用以解消上述問題，其第3目的在於，提 供可確實保持安裝於熱轉寫印字機之印墨帶匣的熱轉寫印 字機的印墨帶匣保持機構。 爲了解決上述第1課題，本發明之熱轉寫用印墨帶匣， 其特徵爲：於將卷裝印墨帶的芯收納於匣本體的熱轉寫用 印墨帶匣中，將上述芯可旋轉自如地配置於匣本體的上壁 及底壁之間，上述底壁形成有用以使芯的中心孔的下端部 繫合於熱轉寫印字機的印墨帶用旋轉軸的貫穿孔，上述上 壁設有可上下搖動的折葉，該折葉具備繫合於上述中心孔 的上端部的短軸部，及可繫合於呈放射狀形成於上述芯的 中心孔的上端周圍的離合器部的繫合爪。 又’上述折葉也可藉由於上述匣本體的上壁設入切槽而 形成。 此外’上述匣本體的側壁也可形成可插脫內部的上述芯 的開口部。 爲了解決上述第2課題，本發明之印墨帶卷取用芯，其 特徵爲：具備筒部；形成於上述筒部內部的中心孔；形成 於上述筒部的上端的凹部；及突設於上述凹部，且設爲從 上述中心孔呈現放射狀，具備錐形面的多個離合器部；而 上述離合器部的錐形面，藉由設爲使芯上端側的前端部的 壁厚較上述凹部側的基端部薄，且芯中心側的部分壁厚較 312/發明說明書(補件)/92-05/92104471 200400124 芯外周側的部分壁厚薄，而相對於上述凹部的垂直方向傾 斜。 又，上述離合器部也可具備作爲上述離合器部的錐形面 而形成的上述第1側面，及作爲相對於上述凹部大致垂直 的面而形成的上述第2側面。 此外，上述筒部也可具備形成於內面的長度方向的突 條。 此外，也可於上述筒部的上下兩端分別設置凸緣，且於 上述筒部的外面形成小徑部。 又，爲了解決上述第2課題，也可組合分別具備上述本 發明之印墨帶卷取用芯的特徵的第1芯及第2芯，用作爲 印墨帶卷取用芯組。 尙，於上述第1芯及第2芯中，作爲本發明之印墨帶卷 取用芯的上述特徵，無共同的必要，也可由各異的特徵所 構成。 爲了解決上述第3課題，本發明之熱轉寫印字機之印墨 帶匣保持機構，其特徵爲：設置使印字輥及印字頭相對地 向抵壓或是分開的方向移動的第1滑行構件、及配置於印 墨帶匣的下部且隨第1滑行構件連動的第2滑行構件，第 2滑行構件形成有繫合部，係在上述第1滑行構件使印字 輥及印字頭從分開狀態向著抵壓方向移動時繫合於印墨帶 匣。 尙，上述繫合部也可爲由從上述第2滑行構件豎起的豎 起片及從豎起片的前端向橫方向突出形成的繫合爪形成爲 8 312/發明說明書(補件)/92-05/92104471 200400124 逆L字形，且，於繫合爪的內側形成從基部向前端傾斜的 傾斜部，將該傾斜部繫合於上述印墨帶匣的底壁的構成。 【實施方式】 首先，參照圖1〜圖7，說明有關本發明之熱轉寫印字 機的構成，尤其是說明印墨帶匣保持機構及印墨帶匣。 圖1中，元件符號1 0 1顯示熱轉寫印字機本體。熱轉寫 印字機本體1 0 1設有印字輥1 0 2及印字頭1 0 3。印字輥1 〇 2 係固定於一定的位置。印字頭1 03係於水平方向可旋轉自 如地設於印字機本體，且由未圖示的彈簧以從印字輥1 02 分開的方式加勢。此外，印字頭1 0 3繫合於第1滑行構件 104的豎起片105。因此，藉由第1滑行構件1〇4作滑行， 而可使印字頭1 0 3相對於印字輥1 0 2向抵壓或是分開的方 向移動。 印字輥1 02及印字頭1 03只要爲相對地向抵壓或是分開 的方向移動即可。據此，也可爲使印字輥1 02連動於第1 滑行構件1 04，且使印字輥1 02相對於固定的印字頭丨03 向分開的方向移動的構成。 其次’於熱轉寫印字機本體1 0 1設置2根旋轉軸1 〇 6、 107，此等旋轉軸106、107上安裝著印墨帶匣1〇8。印墨 帶匣1 0 8的內部收納配置有印墨帶1 〇 9及其卷取用軌道 Π 0。尙，如圖2所示，於印墨帶匣1 〇 8的底壁1 1 1附近， 對應於橫斷印墨帶1 0 9及卷取用軌道1 1 〇間的線p的兩端 部的側壁被切缺而形成繫合支承部1 1 2、1 1 3，此外，一端 部形成貫穿孔1 1 4。 9 312/發明說明書(補件)/92-05/92104471 200400124 此外，印墨帶匣1 〇 8的下部配置有板狀的第2滑行構件 1 1 5。第2滑行構件1 1 5最好由金屬等的強度高的材料所構 成，如圖3 ( a)所示，於其一側的兩端形成一對的繫合部 1 1 8、1 1 9。此等繫合部1 1 8、1 1 9係分別由豎起的豎起片 116及從豎起片116的前端向橫方向突出形成的繫合爪 所形成，且由豎起片116及繫合爪117形成爲逆L字形。 各繫合爪1 1 7的內側形成從基部向前端傾斜的傾斜部 1 2 0。尙，第2滑行構件1 1 5藉由拉伸彈簧1 2 1以經常向第 1滑行構件1 〇4側移動的方式被加勢。 上述印墨帶匣1 0 8的兩端的繫合支承部1 1 2、1 1 3係以安 裝時安裝於對應第2滑行構件1 1 5的繫合部i i 8、i〗9的位 置的形式所形成。 此外，第2滑行構件1 1 5的前端側，如圖4所示形成大 致三角形的孔1 2 2，該三角孔1 2 2上繫合著形成於上述第χ 滑行構件1 04前端的突軸1 23。藉此，以第2滑行構件1 i 5 在一定範圍連動於第1滑行構件1 〇 4進行滑行的方式所構 成。尙’第1滑行構件1 04的滑行量係設定爲第2滑行構 件1 1 5的滑行量的兩倍左右。 上述構成中，於印墨帶交換時，藉由適當的機構使第i 滑行構件1 04向圖式之右側滑行，如圖6及圖7所示，以 使印字輥1 〇 2及印字頭1 〇 3向分開的方向移動。 當如此般使第1滑行構件1 04滑行時，因爲突軸1 2 3位 於第2滑行構件1 1 5的三角孔1 2 2的靠前側，亦即在第1 滑行構件1 04側的圖4所示部位，而在滑行量的一半滑行 10 312/發明說明書(補件)/92-05/92104471 200400124 程度內滑行時，突軸1 2 3僅使三角孔1 2 2的內側移動，因 此，第2滑行構件1 1 5不移動。當第1滑行構件1 04超過 滑行量的一半程度時，因爲上述突軸1 2 3抵接於圖5所示 三角孔1 2 2的內部深側的壁，因此，當在此以上移動時， 突軸1 2 3抵壓第2滑行構件1 1 5而對抗拉伸彈簧1 2 1的彈 性力，第2滑行構件1 1 5也與第1滑行構件1 04連動，移 動至圖6的位置。 此後，從印字輥1 02及印字頭1 03間抽出印墨帶1 〇9， 拆下使用完的印墨帶匣1 〇 8，將新的印墨帶匣1 〇 8通過且 安裝於熱轉寫印字機本體1 〇 1的旋轉軸。此時，如圖3 (a) 所示，第2滑行構件1 1 5的一端的繫合部1 1 8，在其中間 部爲止通過印墨帶匣108的底壁111的貫穿孔114。又， 在印字頭103及印字輥102間設定被印字材（未圖示）後， 使第1滑行構件1 04向逆方向滑行，以印字頭1 〇3抵壓於 印字輥102的方式作移動。 在使第1滑行構件1 04滑行時，如圖6所示，突軸1 23 係位於第2滑行構件1 1 5的三角孔1 2 2的內側的位置，如 圖1及圖3 (b)所示，第2滑行構件1 1 5藉由伸彈簧1 2 1的 彈性力被以時常向著第1滑行構件1 04側移動的方式加 勢’於是，第2滑行構件1 1 5與第1滑行構件1 〇 4連動也 作移動。當第2滑行構件1 1 5藉由彈性力移動時，其繫合 部118、119也向同方向移動，繫合部118、119的繫合爪 1 1 7的傾斜部1 2 0，雖有繫合於印墨帶匣1 〇 8的底壁n ! 的繫合支承部1 1 2、1 1 3，但是，底壁1 1 1藉由繫合爪〗} 7 11 312/發明說明書(補件)/92-05/92104471 200400124 的傾斜部1 2 0被向下方按壓，因此，印墨帶匣1 0 8得到牢 固的保持。 在如此繫合的時點，第2滑行構件1 1 5在圖5的位置停 止’不會再作此以上的移動。另一方面，第1滑行構件1 04 進一步作移動，因此，如圖4所示，突軸1 2 3向著三角孔 1 2 2的靠前側移動，同時，印字頭1 〇 3被按向印字輥1 〇 2。 如此，即可進行印字。 如上述，因爲第2滑行構件Π 5與第1滑行構件1 〇4 — 起移動而繫合於印墨帶匣1 0 8，因此，藉由以金屬等的高 強度材料來構成第2滑行構件11 5，即可將印墨帶匣1 〇 8 確實保持於第2滑行構件1 1 5。據此，在將印墨帶匣1 0 8 安裝於印字機本體時，如圖3 (b)所示，即使在以設於印字 機本體的旋轉軸106、107頂起印墨帶匣108的止旋機構而 解除止旋的情況，仍可充分牢固地保持印墨帶匣1 08。 此外，在第2滑行構件1 1 5的行程前半部完成印墨帶匣 1 08的保持，此後，因爲阻隔了與第1滑行構件1 04的機 械接觸，因此，爲了保持印墨帶匣1 0 8，不是使第2滑行 構件1 1 5來抵壓印字頭1 03，而是由印字頭1 03以一定的 壓力來受印字輥1 02之抵壓，因此，對於印字品質不會產 生影響。 又，上述第1滑行構件1 04及第2滑行構件1 1 5的移動， 不僅在交換印墨帶匣1 08，而且在交換印字用軟管及膠帶 等的消耗品時可同樣施行。 此外，印墨帶匣的繫合部及繫合於該繫合部的第2滑行 12 312/發明說明書(補件)/92-05/92104471 200400124 構件的部位，並不限於上述的例子。 接著，參照圖8 (a)〜圖1 4，說明有關本發明之熱轉寫印 字機之構成，尤其是說明印墨帶卷取用芯及印墨帶匣。 圖8 (a)及圖8(b)爲印墨帶匣的立體圖，圖9爲除去底壁 的狀態的仰視圖，圖10(a)及圖10(b)分別爲芯的立體圖及 剖面圖。上圖中，元件符號A顯示熱轉寫用印墨帶匣。該 印墨帶匣A係爲將卷取熱轉寫用印墨帶2 0 1的芯2 0 2及卷 取印墨帶201用的芯2 03收納於匣本體204內者，芯202 及芯2 0 3係由合成樹脂構成，是在中央筒部a的上下兩端 設有凸緣b，在筒部a的內部形成中心孔2 0 6者，在筒部a 的上端形成凹部2 0 5，在凹部2 0 5形成從上述中心孔2 0 6 呈放射狀形成多數的突片狀離合器部207。此外，在上述 筒部a的內面沿其長度方向形成突條2 0 8。 圖1 0 ( a)及圖1 0 (b )中，尤其顯示以卷取用芯2 0 3的情況 爲例的芯。卷取用芯2 0 3上，在筒部a的外面設有小徑部 26 1，且形成階梯差。藉由印字頭（未圖示）印字後的印墨帶 2 〇 1 ’藉由印字而使印墨被消耗的部位的影響會有歪斜的情 況。爲此，當將印墨帶201卷取於卷取用芯203上時，會 有印墨帶2 0 1的長度方向的外緣部不易滑順地卷取的情 況。但是，藉由設置小徑部2 6 1，即可至最末端爲止將自 芯2 02送出而由印字頭印字後的印墨帶201滑順地卷取。 另一方面，如圖9、圖13及圖14所示，無於芯202設 置筒部a的小徑部2 6 1及凸緣b的必要，也可將印墨帶2 0 1 直接卷取於平滑的筒部a。藉由不設置筒部a的小徑部26】 13 312/發明說明書(補件)/92-05/92104471 200400124 及凸緣b，在匣本體204的內部使芯202及卷取用芯203 更爲接近予以配置，可使匣本體小型化。 此外，芯2 0 2及卷取用芯2 0 3的配置，並無特別的限定， 也可與圖9所示者相反予以配置。 如圖10(a)及圖10(b)所示，在芯202及卷取用芯203的 離合器部207，具備相對於凹部2 0 5的垂直方向傾斜的錐 形面。如圖10 (a)所示，該離合器部2 07的錐形面，係形成 爲使芯上端側之前端部的壁厚較凹部2 0 5側的基端部薄， 且使芯中心側的部分的壁厚較芯外周側的部分的壁厚薄。 此外，離合器部207係設爲與後述的繫合爪221繫合的2 個側面中，僅一側面（第1側面2 07 a)爲錐形面，而另一側 面（第2側面207b)相對於凹部205形成大致垂直的面。 匣本體204係由上壁209、底壁210及側壁211所組成 的盒體狀的構成，內部設有可旋轉自如地收納上述芯202 及印墨帶2 0 1的卷取用芯2 0 3的收納部2 1 2，同時，設有 在將從上述芯202抽出的印墨帶201卷取於卷取用芯203 的途中使印墨帶2 0 1露出用的一對印墨帶小滑輪2 1 3。收 納部212係形成於將印墨帶芯202及卷取用芯2 03定位於 底壁2 1 0上用的圓弧狀突緣2 1 4的內側。印墨帶小滑輪2 1 3 的內側形成有空間，該空間內以位設有熱轉寫印字機的印 字頭（未圖示）的方式所構成。 尙，如圖2所示印墨帶匣1 〇 8之繫合支承部1 1 2、1 1 3 ’ 也可於圖8(a)的上下兩端部的側壁形成缺口。相同地，如 圖2所示印墨帶匣108之貫穿孔114，也可於匣本體204 14 312/發明說明書(補件)/92-05/92104471 200400124 的底壁2 1 0上形成貫穿孔。如此般形成繫合支承部及貫穿 孔，利用與上述印墨帶匣保持機構的組合，即可確實保持 安裝於熱轉寫印字機上的印墨帶匣。 匣本體204之上壁209形成有對應位於芯202及卷取用 芯2 0 3的2個折葉2 1 5。也就是說，折葉2 1 5係藉由於上 壁2 0 9對向形成長短2個略U字型的切槽2 1 7、2 1 8 ，而 形成於切槽2 1 7、2 1 8的內側，2個切槽2 1 7、2 1 8之間形 成有L字形的連結部2 1 9。如圖1 1所示，上述折葉2 1 5的 一端的對應於上述芯2 0 2及卷取用芯2 0 3的各中心的部分 形成有短軸部2 2 0，在短軸部2 2 0的更前端的對應於上述 芯2〇2及卷取用芯2 03的各離合器部2 07的部分形成有突 起狀的繫合爪22 1。此外，上述折葉2 1 5的相反側的一端 形成有可從外部按壓的按壓部222。當按壓該按壓部222 時，折葉2 1 5可以上述連結部2 1 9爲中心上下往返狀搖動。 根據上述構成，因爲在匣本體2 04內的印墨帶芯202及 卷取用芯2 03的中心孔206的上部插入上述匣本體204的 折葉215的短軸部22 0,因而，如圖11所示，印墨帶芯202 及卷取用芯203可以上述短軸部220爲中心自由旋轉。此 外，因爲印墨帶芯2 0 2及卷取用芯2 0 3的中心孔2 0 6的上 端周圍的放射狀離合器部2 07上繫合著上述折葉2 1 5的繫 合爪221，因此，上述印墨帶芯202及卷取用芯203均成 爲鎖住狀態，而無法使其旋轉。據此，在未裝設於熱轉寫 印字機時，不會無故地旋轉。當印墨帶20 1處於鬆弛狀態 時，如圖1 2所示，壓入折葉2 1 5的按壓部222而使折葉 15 312/發明說明書(補件)/92-05/92104471 200400124 215搖動，在將該繫合爪221及印墨帶芯2〇2或是卷取用 心2 0 3的離合器部2 0 7的繫合脫離後，只要以手指或桿來 轉動露出於底壁2 1 0的貫穿孔2 1 6 (參照圖8 )的印墨帶芯 2 〇 2或是卷取用芯2 0 3即可。 尙’也可不將折葉與匣的上壁形成爲一體，而與匣的上 壁另體形成。 如圖1 2所不’在將上述構成的印墨帶匣裝設於熱轉寫 印字機時，只要使設於熱轉寫印字機的旋轉軸2 2 6插穿於 上述匣本體204的底壁210所形成的貫穿孔216即可。然 後，因爲在藉由未圖示的機構將印墨帶匣插入熱轉寫印字 機的指定位置而予以固定時，旋轉軸2 2 6的上端頂起折葉 215的短軸部220，因而，折葉215作搖動，繫合爪221 浮起而與離合器部2 0 7的繫合脫離，從而解除鎖住狀態。 在旋轉軸226的外面沿著其長度方向形成突條2 2 3。當旋 轉軸2 2 6從印墨帶匣A的貫穿孔2 1 6插穿於印墨帶芯2 0 2 及卷取用芯2 0 3的各中心孔2 0 6時，因爲旋轉軸2 2 6的突 條2 2 3與中心孔2 0 6的突條2 0 8繫合，因此，當旋轉軸2 2 6 旋轉時，印墨帶芯2 0 2及卷取用芯2 0 3也旋轉。 此外，如上述，本實施例中，在離合器部2 0 7，僅將與 繫合爪221繫合的2個側面中的第1側面2 07 a設爲錐形 面，而第2側面2 0 7b係相對於凹部2 0 5成爲大致垂直面。 爲此，相對於印墨帶芯202及卷取用芯2 03的鎖住狀態的 旋轉的阻力，可響應使芯旋轉的方向進行變化。也就是說， 沿離合器部207的錐形面（第1側面207a)及繫合爪221繫 16 312/發明說明書(補件)/92-05/92104471 200400124 合的方向進行轉動的情況，與沿離合器部2 0 7的第2側面 2 0 7 b及繫合爪2 2 1繫合的方向進行轉動的情況比較，可容 易進行旋轉。 在未將印墨帶匣裝設於熱轉寫印字機的狀態，印墨帶 2〇1發生鬆弛時，使用者有自行旋轉卷取用芯2 03的必要。 在如此的狀況，藉由採用如上述的離合器部的構成，使用 者只要僅作單方向的旋轉，即可很容易地解除印墨帶2 0 1 的鬆弛。 又，如圖8所示，對應於卷取用芯2 0 3的貫穿孔2 1 6的 周緣設有傾斜面2 1 6 a。藉由該傾斜面2 1 6 a，在未將印墨帶 匣裝設於熱轉寫印字機的狀態而使卷取用芯203旋轉的情 況，可使從匣本體204的底壁210露出的卷取用芯203的 一部分，與使用者的手指平順地接觸。藉此，在印墨帶201 發生鬆弛時，可容易旋轉卷取用芯203。 此外，圖8中，顯示僅將傾斜面2 1 6 a設於對應於卷取用 芯2 03的貫穿孔216的例子，但是，若設於對應於印墨帶 芯2 02的貫穿孔216也可。 圖1 3爲其他印墨帶匣的俯視圖。如該圖所示的匣本體 3 04,也可在匣本體的兩側部將側壁2 1 1切缺而形成開口部 22 4。該開口部224係形成爲可插入及脫離內部的印墨帶芯 202及卷取用芯2 03的大小。爲此，可自由安裝或拆卸由 印墨帶芯2 02及卷取用芯2 03組成的印墨帶卷取用芯組。 也就是說，在安裝印墨帶卷取用芯組時，只要強力按壓折 葉2 15的按壓部22 2而使短軸部22 0上浮，將印墨帶芯202 17 312/發明說明書(補件)/92-05/92104471 200400124 或是卷取用芯2 0 3插入上述開口部2 2 4而被收納於收納部 2 1 2，並放下折葉2 1 5的短軸部2 2 0即可。相對於此，當拆 取內部的印墨帶芯2 02或是卷取用芯203時，也同樣只要

ink ribbon winding core and an ink ribbon cassette for a thermal transfer printer. The present invention also relates to an ink ribbon cassette holding mechanism for stably holding an ink ribbon cassette on a thermal transfer printer. [Prior art] In general, "for displaying the types and functions of electric wires incorporated in electrical equipment such as switchboards," characters and symbols are displayed on the electric wires. In this case, since it is not possible to print directly on the electric wire, the short hose is printed with characters and symbols' in advance, and the electric wire is inserted into the hose for display. In addition, there may be a case where a tape for displaying characters and contents is affixed to the backing paper of a book or a leaflet cover, and the tape is also printed with a title or the like on the surface. In any case, the printing is performed by a thermal transfer printer. The thermal transfer printer presses the hose and tape against the surface of the printed material such as the printing roller, and then presses it on it. Printing ink ribbon and printing head, heating the printing head to dissolve the ink of the printing ink ribbon, and thermally write the characters and marks on the hose and tape. Before the ink ribbon cassette is installed in the printer, the core for taking out the ink ribbon and the core for winding are free, so there may be slack in the winding of the ink ribbon wound around the core. When the printer is set in this state, a defect may occur in the printing of characters. In addition, since the ink ribbon is a consumable, it is necessary to remove the used ink ribbon and insert a new ink ribbon. In the past, the ink ribbon was previously stored in a cassette, and each cassette was loaded. Printing 5 312 / Invention Manual (Supplement) / 92 · 05/92104471 200400124 The cassette loading method of the machine. The advantages of the cassette method are 'easy to use thin ink ribbon' and good mountability. On the contrary, the disadvantage is that when the ink ribbon is used up, all the cassettes must be discarded. In addition to polluting the environment, there is also a problem that the unit price is high. In contrast to the cassette method, there is also a core winding loading method in which only the ink ribbon wound on the core is exchanged. This method is different from the box method in use ', but the unit price is cheap, and there are few discarded parts, so the burden on the environment is also small. In addition, when the ink ribbon cassette is mounted on a thermal transfer printer as described above, it is necessary to keep the ink ribbon cassette in an immovable state. For this reason, the elasticity of the synthetic resin member is used to maintain the pressure or the engagement with the ink ribbon cassette. However, the ink ribbon cassette has a way to prevent the internal ink ribbon from rotating randomly when it is not installed, and a notch is formed on a part of the magazine container so as to be engaged with the ink ribbon shaft to form a spin stopper. The cassette provided with such a rotation-preventing mechanism has a structure in which the tape track rotation shaft provided on the printer main body is mounted on the printer body to lift the rotation-preventing mechanism to release the engagement of the tape track. According to this method, since the lifting force applied to the ink ribbon cassette at the time of release is large, it cannot be held sufficiently in the conventional holding mechanism of the synthetic resin member. SUMMARY OF THE INVENTION The present invention is intended to eliminate the above-mentioned problems. A first object of the present invention is to provide a minimum number of parts that can eliminate the slack in winding of the ink ribbon when it is not mounted. In addition, it can also correspond to not only the cassette method but also the cassette method.

A second object of the present invention is to provide an ink ribbon winding core suitable for the ink ribbon cassette for thermal transfer. Further, the present invention is to solve the above problems, and a third object thereof is to provide an ink ribbon cassette holding mechanism of a thermal transfer printer which can surely hold the ink ribbon cassette mounted on the thermal transfer printer. In order to solve the above-mentioned first problem, the thermal transfer printing ink ribbon cassette of the present invention is characterized in that the core of the roll printing ribbon is stored in the thermal transfer printing ink ribbon cassette of the cassette body, and the core is rotatable. It is freely arranged between the upper wall and the bottom wall of the cassette body, and the bottom wall forms a through hole for connecting the lower end portion of the center hole of the core to the rotary shaft for the ink ribbon of the thermal transfer printer. The wall is provided with a flap capable of swinging up and down, the flap having a short shaft portion connected to the upper end portion of the center hole, and a clutch portion that can be connected to the clutch portion radially formed around the upper end of the center hole of the core. Fasten the claws. The above-mentioned folding leaf can also be formed by providing a notch in the upper wall of the box body. In addition, 'the side wall of the box body may form an opening portion of the core which can be inserted and removed. In order to solve the above-mentioned second problem, the ink ribbon winding core according to the present invention includes a tube portion, a central hole formed inside the tube portion, a concave portion formed at an upper end of the tube portion, and a protrusion provided on the tube portion. The recessed portion is provided with a plurality of clutch portions that are radially formed from the center hole and have a tapered surface. The tapered surface of the clutch portion is configured such that a wall thickness of a tip portion of an upper end side of the core is larger than the recessed portion. The base end portion on the side is thin, and the wall thickness of the part on the core center side is thinner than the wall thickness of the part on the outer peripheral side of the core, which is inclined to the vertical direction of the recessed portion. The clutch portion may include the first side surface formed as a tapered surface of the clutch portion, and the second side surface formed as a surface substantially perpendicular to the recessed portion. The cylindrical portion may be provided with a protrusion formed in the longitudinal direction on the inner surface. In addition, flanges may be provided at the upper and lower ends of the cylindrical portion, respectively, and a small diameter portion may be formed on the outer surface of the cylindrical portion. In order to solve the above-mentioned second problem, a first core and a second core each having the characteristics of the ink ribbon winding core of the present invention described above may be combined to be used as an ink ribbon winding core group. That is, among the above-mentioned first and second cores, the above-mentioned characteristics of the ink ribbon winding core of the present invention are not necessarily necessary in common, and may be constituted by different characteristics. In order to solve the above-mentioned third problem, the ink ribbon cassette holding mechanism of the thermal transfer printer of the present invention is characterized in that a first sliding member is provided to move the printing roller and the printing head in a relatively opposing or separated direction. And a second sliding member which is arranged on the lower part of the ink ribbon cassette and is linked with the first sliding member, and the second sliding member is formed with a coupling part, and the printing roller and the printing head are moved from the separated state toward the first sliding member It is fastened to the ink ribbon cassette when moving in the pressing direction. Alas, the engaging portion may be formed by a rising piece erected from the second sliding member and a engaging claw projecting from the front end of the rising piece in a lateral direction as 8 312 / Invention Specification (Supplement) / 92-05 / 92104471 200400124 An inverse L-shape, and an inclined portion inclined from the base to the front end is formed inside the engaging claw, and the inclined portion is connected to the bottom wall of the ink ribbon cassette. [Embodiment] First, the structure of a thermal transfer printer according to the present invention will be described with reference to Figs. 1 to 7, and particularly, an ink ribbon cassette holding mechanism and an ink ribbon cassette will be described. In FIG. 1, the component symbol 1101 shows the body of the thermal transfer printer. Thermal transfer printing The printer body 101 is provided with a printing roller 10 and a printing head 103. The printing roller 1 02 is fixed at a certain position. The printing head 1 03 is rotatably provided in the printer body in a horizontal direction, and is biased by a spring (not shown) to be separated from the printing roller 10 02. The printing head 103 is connected to the rising piece 105 of the first sliding member 104. Therefore, by sliding the first sliding member 104, the printing head 103 can be moved in a direction of being pressed against or separated from the printing roller 102. The printing roller 10 02 and the printing head 103 may be moved in the direction of relative pressure or separation. Accordingly, a configuration may be adopted in which the printing roller 102 is linked to the first sliding member 104, and the printing roller 102 is moved in a direction separated from the fixed printing head 丨 03. Secondly, two rotation shafts 106 and 107 are provided on the thermal transfer printer body 101, and the ink ribbon cassette 108 is mounted on the rotation shafts 106 and 107. The ink ribbon cassette 108 contains an ink ribbon 109 and a winding track Π 0 therein. That is, as shown in FIG. 2, near the bottom wall 1 1 1 of the ink ribbon cassette 10, corresponding to both ends of the line p that traverses the ink ribbon 1 10 and the winding track 1 1 10 The side wall is cut out to form a coupling support portion 1 1 2, 1 1 3, and a through hole 1 1 4 is formed at one end portion. 9 312 / Invention Manual (Supplement) / 92-05 / 92104471 200400124 In addition, a plate-like second sliding member 1 1 5 is arranged at the lower part of the ink ribbon cassette 108. The second sliding member 1 1 5 is preferably made of a high-strength material such as metal. As shown in FIG. 3 (a), a pair of engaging portions 1 1 8 and 1 1 9 are formed at both ends of one side. . These engaging portions 1 1 8 and 1 1 9 are respectively formed by the erecting rising piece 116 and the engaging claws protruding from the front end of the erecting piece 116 in the lateral direction. The engaging claw 117 is formed in an inverted L shape. The inside of each of the engaging claws 1 1 7 is formed with an inclined portion 1 2 0 which is inclined from the base to the front end. That is, the second sliding member 1 1 5 is energized by the tension spring 1 2 1 so as to constantly move toward the first sliding member 104 side. The coupling support portions 1 1 2, 1 1 3 at both ends of the above-mentioned ink ribbon cassette 108 are in the form of being mounted on the coupling portions ii 8 and i 9 corresponding to the second sliding member 1 1 5 at the time of installation. Formed. In addition, a substantially triangular hole 1 2 2 is formed on the front end side of the second sliding member 1 1 5 as shown in FIG. 4. A protruding shaft formed at the front end of the second χ sliding member 104 is engaged with the triangular hole 1 2 2. 1 23. Thereby, the second taxiing member 1 i 5 is configured to interlock with the first taxiing member 104 in a certain range to perform taxiing. That is, the amount of coasting of the first coasting member 104 is set to about twice the amount of coasting of the second coasting member 115. In the above configuration, when the ink ribbon is exchanged, the i-th sliding member 104 is slid to the right side of the figure by an appropriate mechanism, as shown in FIGS. 6 and 7, so that the printing roller 1 02 and the printing head 1 〇3 moves in a separate direction. When the first taxiing member 1 04 is taxied in this way, the protruding shaft 1 2 3 is located on the front side of the triangular hole 1 2 2 of the second taxiing member 1 1 5, that is, the figure on the side of the first taxiing member 1 04 4 while sliding at half of the amount of sliding 10 312 / Invention Specification (Supplement) / 92-05 / 92104471 200400124, the protruding shaft 1 2 3 moves only the inside of the triangular hole 1 2 2 The second sliding member 1 1 5 does not move. When the first taxiing member 104 exceeds half of the taxiing amount, the above-mentioned protruding shaft 1 2 3 abuts against the wall on the deep side of the triangular hole 1 2 2 shown in FIG. 5. Therefore, when moving above this, The protruding shaft 1 2 3 presses against the second sliding member 1 1 5 and opposes the elastic force of the tension spring 1 2 1. The second sliding member 1 1 5 is also linked with the first sliding member 1 04 and moves to the position shown in FIG. 6. After that, take out the ink ribbon 1 009 between the printing roller 102 and the printing head 103, remove the used ink ribbon cassette 1 08, pass the new ink ribbon cassette 108, and install it in the thermal transfer The rotation axis of the printer body 〇1. At this time, as shown in FIG. 3 (a), the engaging portion 1 1 8 at one end of the second sliding member 1 15 passes through the through hole 114 of the bottom wall 111 of the ink ribbon cassette 108 up to the middle portion. In addition, after the printing material (not shown) is set between the printing head 103 and the printing roller 102, the first sliding member 104 is slid in the reverse direction, and the printing head 103 is moved against the printing roller 102 to move. . When the first taxiing member 10 04 is taxied, as shown in FIG. 6, the protruding shaft 1 23 is located inside the triangular hole 1 2 2 of the second taxiing member 1 15, as shown in FIGS. 1 and 3 (b). As shown, the second sliding member 1 1 5 is boosted by the elastic force of the extension spring 1 2 1 so that it is often moved toward the first sliding member 1 04 side. Therefore, the second sliding member 1 1 5 and the first sliding member 1 〇4 linkage also moves. When the second sliding member 1 1 5 is moved by the elastic force, its engaging portions 118 and 119 also move in the same direction, and the engaging claws 1 1 7 of the engaging portions 118 and 119 have inclined portions 1 2 0. The coupling support portion 1 1 2, 1 1 3 which is coupled to the bottom wall n! Of the ink ribbon cassette 1 008, but the bottom wall 1 1 1 is connected by the coupling claws.} 7 11 312 / Invention Specification (Supplement Pieces) / 92-05 / 92104471 200400124, the inclined portion 1 2 0 is pressed downward, so the ink ribbon cassette 108 is firmly held. At this point of engagement, the second sliding member 1 15 stops at the position shown in Fig. 5 and will not move more than this. On the other hand, as the first sliding member 1 04 moves further, as shown in FIG. 4, the protruding shaft 1 2 3 moves toward the front side of the triangular hole 1 2 2, and at the same time, the printing head 1 03 is pressed toward the printing. Roller 〇2. This allows printing. As described above, the second sliding member Π 5 and the first sliding member 10 are moved together to be coupled to the ink ribbon cassette 108. Therefore, the second sliding member is made of a high-strength material such as metal. 11 5, the ink ribbon cassette 1 08 can be surely held on the second sliding member 1 1 5. Accordingly, when the ink ribbon cassette 108 is mounted on the printer body, as shown in FIG. 3 (b), even when the ink ribbon cassette 108 is lifted up with the rotation shafts 106 and 107 provided on the printer body. In the case where the rotation stop mechanism is used to release the rotation stop, the ink ribbon cassette 108 can still be held sufficiently firmly. In addition, the holding of the ink ribbon cassette 108 is completed in the first half of the stroke of the second sliding member 115, and thereafter, since the mechanical contact with the first taxiing member 104 is blocked, in order to maintain the ink ribbon cassette 10 8. Instead of pressing the second sliding member 1 1 5 to press the printing head 10 03, the printing head 10 03 is pressed by the printing roller 10 02 with a certain pressure. Therefore, the printing quality will not be affected. The movement of the first sliding member 104 and the second sliding member 115 can be performed not only when the ink ribbon cassette 108 is exchanged, but also when consumables such as printing hoses and tapes are exchanged. In addition, the engaging portion of the ink ribbon cassette and the second sliding portion 12 312 / Invention Specification (Supplement) / 92-05 / 92104471 200400124 of the engaging portion are not limited to the above examples. Next, the constitution of the thermal transfer printer according to the present invention will be described with reference to Figs. 8 (a) to 14 and, in particular, the ink ribbon winding core and the ink ribbon cassette will be described. Figures 8 (a) and 8 (b) are perspective views of the ink ribbon cassette, Figure 9 is a bottom view of the state with the bottom wall removed, and Figures 10 (a) and 10 (b) are perspective and sectional views of the core, respectively. . In the figure above, the component symbol A shows the ink ribbon cassette for thermal transfer. The ink ribbon cassette A is a core 202 and a core 2 and core 2 which store the core 2 02 of the ink ribbon for thermal transfer 201 and the core 2 03 of the ink ribbon 201 for winding. The 0 3 series is made of synthetic resin, and is provided with flanges b at the upper and lower ends of the central cylindrical portion a, a central hole 206 is formed inside the cylindrical portion a, and a concave portion 2 5 is formed at the upper end of the cylindrical portion a. A plurality of tab-like clutch portions 207 are formed in the recessed portion 2 05 in a radial form from the center hole 2 0 6. Further, a projection 208 is formed on the inner surface of the cylindrical portion a along the longitudinal direction thereof. In Fig. 10 (a) and Fig. 10 (b), the core is specifically shown by taking the case of the winding core 203 as an example. On the winding core 203, a small diameter portion 261 is provided on the outer surface of the tube portion a, and a step is formed. The printing ink ribbon 2 0 1 ′ after being printed by a printing head (not shown) may be skewed due to the influence of the portion where the printing ink is consumed by printing. For this reason, when the ink ribbon 201 is wound on the winding core 203, the outer edge portion of the ink ribbon 201 in the longitudinal direction may not be easily wound. However, by providing the small-diameter portion 2 61, it is possible to send out from the core 2 02 to the extreme end and smoothly take up the ink ribbon 201 after being printed by the print head. On the other hand, as shown in FIGS. 9, 13, and 14, it is not necessary to provide the small-diameter portion 2 6 1 and the flange b of the tube portion a to the core 202, and the ink ribbon 2 0 1 can be directly wound up.于 Smooth tube a. By not providing the small diameter portion 26 of the tube portion a] 13 312 / Invention Specification (Supplement) / 92-05 / 92104471 200400124 and the flange b, the core 202 and the winding core 203 are changed inside the cassette body 204 By arranging for closeness, the cartridge body can be miniaturized. In addition, the arrangement of the core 202 and the winding core 203 is not particularly limited, and may be arranged opposite to that shown in FIG. 9. As shown in Figs. 10 (a) and 10 (b), the clutch portion 207 of the core 202 and the winding core 203 is provided with a tapered surface inclined with respect to the vertical direction of the recessed portion 205. As shown in FIG. 10 (a), the tapered surface of the clutch portion 2007 is formed so that the wall thickness of the front end portion of the core upper side is thinner than the base end portion of the concave portion 250 side, and the core center side The wall thickness of the portion is thinner than the wall thickness of the portion on the outer peripheral side of the core. In addition, the clutch portion 207 is configured so that only one side surface (the first side surface 2 07 a) is a tapered surface, and the other side surface (the second side surface 207 b) is opposed to the two side surfaces engaged with the engaging claw 221 described later. A substantially vertical surface is formed in the recessed portion 205. The cartridge body 204 is a box-shaped structure composed of an upper wall 209, a bottom wall 210, and a side wall 211, and a winding core 2 0 3 for rotatably accommodating the core 202 and the ink ribbon 2 01 is provided inside. The storage unit 2 1 2 is also provided with a pair of small ink ribbon pulleys for exposing the ink ribbon 201 while the ink ribbon 201 withdrawn from the core 202 is wound around the winding core 203. 2 1 3. The receiving portion 212 is formed inside the arc-shaped flange 2 1 4 for positioning the ink ribbon core 202 and the winding core 20 03 on the bottom wall 2 10. A space is formed inside the ink ribbon small pulley 2 1 3, and the space is constituted by a print head (not shown) of a thermal transfer printer. Alas, as shown in FIG. 2, the coupling support portions 1 1 2, 1 1 3 ′ of the ink ribbon cassette 108 may be formed with notches on the side walls of the upper and lower ends of FIG. 8 (a). Similarly, the through hole 114 of the ink ribbon cassette 108 as shown in FIG. 2 can also be formed in the bottom wall 2 1 0 of the cassette body 204 14 312 / Invention Specification (Supplement) / 92-05 / 92104471 200400124. . By forming the coupling support portion and the through-hole in this manner, the ink ribbon cassette mounted on the thermal transfer printer can be reliably held by using the combination with the ink ribbon cassette holding mechanism described above. The upper wall 209 of the box body 204 is formed with two folding leaves 2 1 5 corresponding to the core 202 and the winding core 203. That is to say, the folding leaf 2 1 5 is formed in the cut grooves 2 1 7 and 2 1 8 by forming two slightly U-shaped cut grooves 2 1 7 and 2 1 8 opposite to the upper wall 2 9. Inside, two L-shaped connecting portions 2 1 9 are formed between the two notches 2 1 7 and 2 1 8. As shown in FIG. 11, a short-axis portion 2 2 0 is formed at a portion of one end of the folding leaf 2 1 5 corresponding to each of the core 2 0 2 and the winding core 2 0 3. At the front end of 20, a portion corresponding to each of the clutch portions 2007 of the core 202 and the winding core 203 is formed with a protruding engagement claw 221. In addition, a pressing portion 222 that can be pressed from the outside is formed on one end on the opposite side of the hinge 2 15. When the pressing portion 222 is pressed, the folding leaf 2 1 5 can swing back and forth around the connecting portion 2 1 9 as a center. According to the above configuration, the short shaft portion 220 of the flap 215 of the cartridge body 204 is inserted into the upper part of the ink ribbon core 202 and the core 206 of the winding core 203 in the cartridge body 204, as shown in FIG. As shown in FIG. 11, the ink ribbon core 202 and the winding core 203 can freely rotate around the short shaft portion 220. In addition, since the radial clutch portion 20 07 around the upper end of the center hole 2 0 6 of the ink ribbon core 202 and the winding core 2 0 3 is engaged with the engaging claw 221 of the above-mentioned folding leaf 2 1 5, Therefore, the ink ribbon core 202 and the winding core 203 are locked, and cannot be rotated. Accordingly, when it is not installed in a thermal transfer printer, it does not rotate for no reason. When the ink ribbon 20 1 is in a relaxed state, as shown in FIG. 12, the pressing portion 222 of the folding leaf 2 1 5 is pressed to make the folding leaf 15 312 / Invention Manual (Supplement) / 92-05 / 92104471 200400124 215 After shaking, after the engagement of the engaging claw 221 and the ink ribbon core 202 or the clutch portion 2 7 of the winding core 2 0 3 is disengaged, the finger or the lever can be rotated to expose the bottom wall 2 1 The through-hole 2 1 (see FIG. 8) of 0 may be the ink ribbon core 2 02 or the winding core 2 0 3.尙 'may not be formed integrally with the upper wall of the box, but may be formed separately from the upper wall of the box. As shown in FIG. 12, when the ink ribbon cassette having the above structure is installed on a thermal transfer printer, the rotation shaft 2 2 6 provided on the thermal transfer printer needs to be inserted through the bottom of the cartridge body 204. The through hole 216 formed by the wall 210 is sufficient. Then, when the ink ribbon cassette is inserted into a designated position of the thermal transfer printer and fixed by a mechanism (not shown), the upper end of the rotary shaft 2 2 6 pushes up the short shaft portion 220 of the folding leaf 215, The hinge 215 swings, and the engagement claw 221 floats and disengages from the engagement of the clutch portion 207, thereby releasing the locked state. A protrusion 2 2 3 is formed on the outer surface of the rotation shaft 226 along its length direction. When the rotating shaft 2 2 6 is inserted through the through hole 2 1 6 of the ink ribbon cassette A into each central hole 2 0 6 of the ink ribbon core 2 0 2 and the winding core 2 0 3, the rotating shaft 2 2 The protrusion 2 2 3 of 6 is engaged with the protrusion 2 0 8 of the center hole 2 0 6. Therefore, when the rotation shaft 2 2 6 rotates, the ink ribbon core 2 2 and the winding core 2 0 3 also rotate. . As described above, in the present embodiment, in the clutch portion 207, only the first side surface 2 07 a of the two side surfaces engaged with the engagement claw 221 is a tapered surface, and the second side surface 2 0 7b is a substantially vertical plane with respect to the recessed portion 205. Therefore, the resistance to rotation of the ink ribbon core 202 and the winding core 203 in the locked state can be changed in response to the direction in which the core is rotated. In other words, when the conical surface (the first side surface 207a) of the clutch portion 207 and the engaging claws 221, 16 and 312 / Invention Specification (Supplement) / 92-05 / 92104471 200400124 are rotated, the rotation direction Compared with the case where the second side surface 2 0 7 b of the clutch portion 2 0 7 and the engaging claw 2 2 1 are rotated, the rotation can be easily performed. When the ink ribbon cassette is not installed in the thermal transfer printer and the ink ribbon 201 is loosened, it is necessary for the user to rotate the winding core 20 03 by himself. In such a situation, by adopting the configuration of the clutch unit as described above, the user can easily release the slack in the ink ribbon 2 0 1 by only performing one-way rotation. As shown in FIG. 8, the inclined surface 2 1 6 a is provided on the periphery of the through hole 2 1 6 corresponding to the winding core 2 0 3. With the inclined surface 2 1 6 a, when the take-up core 203 is rotated without the ink ribbon cassette installed in the thermal transfer printer, the bottom surface 210 of the cassette body 204 can be exposed. A part of the winding core 203 comes into smooth contact with a user's finger. Thereby, when the ink ribbon 201 is loosened, the winding core 203 can be easily rotated. In addition, FIG. 8 shows an example in which only the inclined surface 2 1 6 a is provided in the through hole 216 corresponding to the winding core 20 03. However, if the through hole 216 is provided in the ink ribbon core 202 as well, can. Figure 13 is a top view of another ink ribbon cassette. As shown in the figure, in the box body 304, the side wall 2 1 1 may be cut out on both sides of the box body to form an opening 22 4. The opening portion 224 is formed to have a size such that the ink ribbon core 202 and the winding core 202 can be inserted into and removed from the inside. For this reason, the ink ribbon winding core set consisting of the ink ribbon core 202 and the winding core 203 can be freely installed or removed. That is, when installing the ink ribbon winding core set, as long as the pressing portion 22 2 of the folding leaf 2 15 is strongly pressed to cause the short shaft portion 22 0 to float, the ink ribbon core 202 17 312 / Invention Specification (Supplement Pieces) / 92-05 / 92104471 200400124 or the winding core 2 0 3 is inserted into the opening 2 2 4 and stored in the storage portion 2 1 2, and the short shaft portion 2 2 5 of the folding leaf 2 1 5 is can. In contrast, when removing the inner ink ribbon core 202 or the winding core 203, similarly, as long as the pressing portion 222 of the folding leaf 215 is strongly pressed to float the short shaft portion 220, it is then extracted from the opening The ink ribbon core 202 or the winding core 203 can be used. Figure 14 is a top view of another print cartridge. The cartridge body 400 as shown in FIG. 14 may include the same openings 2 24a and 2 24b as those of the cartridge body shown in FIG. 13, but in the vicinity of the opening 224 a into which the ink ribbon core 202 is inserted or detached. A convex strip 2 2 5 is formed on the bottom wall. The convex strip 2 2 5 is provided to reduce the contact resistance between the core and the bottom wall of the cartridge body when inserting and removing the core, so that the ink ribbon can be exchanged more easily. Except for the protrusions 2 2 5, the box body 40 04 shown in FIG. 14 is the same as the box bodies 204 and 30 04 shown in FIGS. 8 to 13, and detailed description is omitted. In addition, Fig. 14 shows an example in which three ridges 2 2 5 are provided only on the side of the opening 224a. However, the shape, arrangement, and number of the ridges are not particularly limited. Alternatively, a ridge may be provided on the bottom wall of the opening portion 224b on the side of the winding core 203. The present invention is not limited to the contents described in the above embodiments, as long as various changes can be made within the technical scope of the present invention, the present invention naturally includes such changed contents. This application is based on a Japanese patent application filed on February 28, 2002 (Japanese Patent Application No. 2002-054824) and a Japanese patent application filed on February 28, 2002 (Japanese Patent Application No. 2 002 -05 4 8 2 5), the contents of which are incorporated into this specification for reference. (Industrial Applicability) 18 312 / Invention Specification (Supplement) / 92-05 / 92104471 200400124 As described above, in the ink ribbon winding core and the ink ribbon cassette of the present invention, since the ink ribbon 2 0 1 is installed on the box body 2 0 4. Therefore, when installing on the thermal transfer printer, the rotation shaft 226 provided on the thermal transfer printer needs to be inserted through the bottom wall of the box body 204. The manner of the through hole 216 formed by 210 may be installed. According to this, the ink ribbon 201 is easy to use and has excellent installation properties. In addition, when the flap is formed integrally with the upper wall of the cassette, the slack in the non-installed ink ribbon can be eliminated with a minimum number of parts. In addition, when the opening portion is formed on the side of the cartridge body 204, only the ink ribbon 201 wound around the core 202 can be exchanged. Therefore, it can also be used as a core take-up installation method. Thereby, not only is simple to use, the unit price is cheap, and the number of discarded parts is small. Therefore, the load on the environment can be reduced, and at the same time, it can support not only the cassette method but also the core winding method. Further, in the ink ribbon cassette holding mechanism of the thermal transfer printer of the present invention, the second sliding member moves together with the first sliding member to be coupled to the ink ribbon cassette. In this way, the ink ribbon cassette mounted on the thermal transfer printer can be surely held by the second sliding member.
