〔従来の技術〕 [Prior art]

従来記録装置、例えば熱転写プリンタでは、印字ヘッドと用紙との間にテープ状のインクリボンを送給し、印字ヘッドを支持する記録装置のキヤリッジの移動に応じてインクリボンを送りながら印字を行なう。 Conventional recording apparatus, for example a thermal transfer printer, feeds send a tape-like ink ribbon between the print head and the paper, for printing while feeding the ink ribbon in accordance with the movement of the carriage of the recording apparatus that supports the print head. インクリボンはインクリボンカセット(以下カセットと称す)内に収納され、該インクリボンの一端はフリーローラである供給リールに捲回され、他端は駆動ローラである捲き取りリールによって捲き取られる。 The ink ribbon is housed in an ink ribbon set (hereinafter referred to as the cassette), one end of the ink ribbon is wound on the supply reel is a free roller, and the other end is taken Maki by Maki-up reel is driven rollers. 上記の供給リールと捲き取りリール間に張設されたインクリボンを複数のリボンガイドで導いて上下方向に位置を正した後に、カセット前面の印字ヘッド受入れ用開口凹所を通過するように送られる。 After correct position in the vertical direction guides the ink ribbon is stretched between Maki-up reel and said supply reel in a plurality of ribbon guides, sent to pass the print head receiving opening recess of the cassette front .

このようなカセットは、用紙上に記録される印字の印字品質が低下しないように、装着したカセットがキャリッジに対して前後左右及び上下に確実に位置決めすることが必要である。 Such cassettes, as print quality of the print to be recorded on the sheet is not reduced, it is necessary to reliably positioned to the left and right and up and down back and forth relative to mounting the cassette carriage. そうでないとリボンの巻取り動作に不具合を生じ、特に上下移動が大きいと印字ヘッドがリボン幅から上下方向にはみ出して印字に欠けを生ずることがある。 Otherwise the resulting defect in the winding operation of the ribbon, may be particularly the print head up and down movement is large resulting in lack printing protrude vertically from the ribbon width. また印字ヘッドは消耗品であり、半永久的使用のキヤリッジに対して次々に新しいカセットを取換えるためのキヤリッジに対してカセットが着脱自在であることが要求される。 The printhead is a consumable item, the cassette relative to carriage for changing preparative new cassettes one after another with respect to the carriage of semi-permanent use is required to be detachable.
