Abstract

Provided is a cassette that can suppress upsizing even though accommodating a laminating tape roll. A cassette 10 having a dual-layer structure is provided with: a printing tape roll (first roll) 26 which is arranged in a first layer L1 and on which a printing tape (first tape) 22 to be printed is wound; and a laminating tape roll (second roll) 64 which is arranged in a second layer L2 and on which a laminating tape (second tape) 60 to be laminated on the printing tape (first tape) 22 is wound. At least a part of the printing tape roll 26 overlaps at least a part of the laminating tape roll 64 in a first direction parallel to a first rotation central line C1 which is the rotation center of the printing tape roll 26. As a result, it is possible to miniaturize the cassette 10 compared with a case in which at least a part of the printing tape roll 26 does not overlap at least a part of the laminating tape roll 64 in the first direction.

Description

カセットcassette
　本発明は、印刷機に脱着可能に装着されるカセットに関するものである。 The present invention relates to a cassette that is detachably attached to a printing machine.
　従来、テープと、テープに印刷を行うためのインクリボンとを備えたカセットが知られている。例えば特許文献１に記載のインクリボンカートリッジは、リボンカートリッジと印刷シートカートリッジとを備える。リボンカートリッジの中には、インクリボンと、インクリボンを巻き取るための巻取軸とが収容される。印刷シートカートリッジの中には、印刷シートが収容される。印刷シートカートリッジは、リボンカートリッジの上方に重ね合わされて、リボンカートリッジと一体化される。リボンカートリッジには、プリンタのヘッドが挿入されるヘッド開口部が設けられる。印刷シートカートリッジのうち印刷シートのロールに対してヘッド開口部とは反対の位置には、印刷シートが通過するシート開口部が設けられる。印刷シートは、ロールから引き出された後、シート開口部を介して印刷シートカートリッジの外に出される。その後、印刷シートは、印刷シートカートリッジの外周壁の周りを通ってヘッド開口部を通過する。ヘッド開口部では、印刷シートとインクリボンとが互いに重ね合されて、プリンタの印刷ヘッドによって印刷が行われる。印刷に用いられたインクリボンは、リボンカートリッジ内において巻取軸によって巻き取られる。 Conventionally, a cassette equipped with a tape and an ink ribbon for printing on the tape is known. For example, the ink ribbon cartridge described in Patent Document 1 includes a ribbon cartridge and a printing sheet cartridge. The ink ribbon and a winding shaft for winding the ink ribbon are housed in the ribbon cartridge. The print sheet is housed in the print sheet cartridge. The print sheet cartridge is overlaid on top of the ribbon cartridge and integrated with the ribbon cartridge. The ribbon cartridge is provided with a head opening into which the printer head is inserted. A sheet opening through which the printing sheet passes is provided at a position of the printing sheet cartridge opposite to the head opening with respect to the roll of the printing sheet. After being pulled out of the roll, the print sheet is taken out of the print sheet cartridge through the sheet opening. The print sheet then passes around the outer peripheral wall of the print sheet cartridge and passes through the head opening. At the head opening, the print sheet and the ink ribbon are superposed on each other, and printing is performed by the print head of the printer. The ink ribbon used for printing is wound by a take-up shaft in the ribbon cartridge.
