Description

すなわち、本発明に係るプリンタは、搬送路に沿って記録媒体を搬送する搬送手段と、固定刃及び固定刃に対して可動する可動刃を有し、固定刃を搬送路にある記録媒体に接触させた状態で固定刃に対して可動刃を移動させることにより記録媒体を切断するカット手段とを具備してなり、記録媒体の移動時に記録媒体と固定刃とを離間させる接離機構を設けたことを特徴とする。 In other words, the printer according to the present invention includes a conveying unit that conveys the recording medium along the conveying path, a fixed blade and a movable blade that is movable with respect to the fixed blade, and the fixed blade contacts the recording medium in the conveying path. it was and a cutting means for cutting the recording medium by moving the movable blade against the fixed blade in a state of being provided with a separation mechanism for separating the recording medium and the fixed blade when moved in the recording medium It is characterized by that.

この構成によれば、接離機構により記録媒体の移動時に記録媒体と固定刃とを離間させるので、例えば記録媒体の搬送中に記録媒体と固定刃とが接触することがなくなり、記録媒体の損傷や紙粉の発生を防止し、固定刃に起因する不具合を伴うことなく記録媒体を適切に搬送することができる。しかも、印刷品質を損なう原因となる記録媒体の損傷を防止して印刷品質を向上させることができるとともに、プリンタに悪影響を与える紙粉の発生を防止してプリンタの故障率を低減させることができる。 According to this configuration, since to separate the recording medium when moving the recording medium and the fixed blade by contact and separation mechanism, for example, it prevents the recording medium during conveyance of the recording medium and the fixed blade is in contact, the recording medium The occurrence of damage and paper dust can be prevented, and the recording medium can be transported appropriately without any defects caused by the fixed blade. Moreover, it is possible to improve the print quality by preventing damage to the recording medium that causes the print quality to be impaired, and to reduce the failure rate of the printer by preventing the occurrence of paper dust that adversely affects the printer. .

固定刃及び可動刃の位置決めを簡易化して切断機能を容易に確保するためには、搬送路のうち固定刃が臨む部位に記録媒体を案内するガイド部を有し、前記接離機構は、記録媒体の移動時に前記ガイド部による記録媒体の案内先を固定刃に接触する接触位置から固定刃と離間する非接触位置に切り替えることが好ましい。 In order to simplify the positioning of the fixed blade and the movable blade and easily ensure the cutting function, the conveyance path has a guide portion that guides the recording medium to a portion where the fixed blade faces, and the contact / separation mechanism it is preferable to switch to a non-contact position separated from the fixed blade from a contact position contacting the guiding destination recording medium by the guide portion when moving the medium to the fixed blade.

以上説明したように、本実施形態では、搬送路Ｌｉに沿って記録媒体Ｐａを搬送する搬送手段２と、固定刃４１及び固定刃４１に対して可動する可動刃４２を有し、固定刃４１を搬送路Ｌｉにある記録媒体Ｐａに接触させた状態で固定刃４１に対して可動刃４２を移動させることにより記録媒体Ｐａを切断するカット手段４とを具備してなり、記録媒体Ｐａの移動時に記録媒体Ｐａと固定刃４１とを距離Ｄｓ離間させる接離機構６を設けているので、例えば記録媒体Ｐａの搬送中に記録媒体Ｐａと固定刃４１とが接触することがなくなり、記録媒体Ｐａの損傷や紙粉の発生を防止し、固定刃４１に起因する不具合を伴うことなく記録媒体Ｐａを適切に搬送することが可能となる。しかも、印刷品質を損なう原因となる記録媒体Ｐａの損傷を防止して印刷品質を向上させることが可能となるうえ、プリンタに悪影響を与える紙粉の発生を防止してプリンタの故障率を低減させることが可能となる。 As described above, in the present embodiment, the fixed unit 41 includes the transport unit 2 that transports the recording medium Pa along the transport path Li, the fixed blade 41, and the movable blade 42 that is movable with respect to the fixed blade 41. the result was and a cutting means 4 for cutting the recording medium Pa by moving the movable blade 42 against the fixed blade 41 being in contact to a recording medium Pa to the transport path Li, transfer of the recording medium Pa Since the contact / separation mechanism 6 that separates the recording medium Pa and the fixed blade 41 by the distance Ds is provided during the movement, for example, the recording medium Pa and the fixed blade 41 do not come into contact with each other during the conveyance of the recording medium Pa. Pa damage and generation of paper dust can be prevented, and the recording medium Pa can be appropriately transported without causing problems due to the fixed blade 41. In addition, it is possible to improve the print quality by preventing damage to the recording medium Pa, which causes the print quality to be impaired, and to reduce the failure rate of the printer by preventing the occurrence of paper dust that adversely affects the printer. It becomes possible.

仮に、上記接離機構を、固定刃４１を移動させて記録媒体Ｐａと固定刃４１とを離間させるように構成する場合には固定刃４１と可動刃４２との位置決めが難しく、適切な切断機能を確保するのが難しいが、本実施形態では、搬送路Ｌｉのうち固定刃４１が臨む部位に記録媒体Ｐａを案内するガイド部２２を有し、接離機構６は、記録媒体Ｐａの移動時にガイド部２２による記録媒体Ｐａの案内先を固定刃４１に接触する接触位置ｐｏ１から固定刃４１と離間する非接触位置ｐｏ２に切り替えるので、固定刃４１を移動させる接離機構に比べて固定刃及び可動刃の位置決めを簡易化して切断機能を容易に確保することが可能となる。 If the contact / separation mechanism is configured to move the fixed blade 41 to separate the recording medium Pa and the fixed blade 41, it is difficult to position the fixed blade 41 and the movable blade 42, and an appropriate cutting function is provided. it is difficult to ensure, in this embodiment, it has a guide portion 22 for guiding the recording medium Pa at a site facing the fixed blade 41 of the conveyance path Li, separation mechanism 6 is moved in the recording medium Pa Since the guide destination of the recording medium Pa by the guide unit 22 is sometimes switched from the contact position po1 that contacts the fixed blade 41 to the non-contact position po2 that is separated from the fixed blade 41, the fixed blade compared to the contact / separation mechanism that moves the fixed blade 41 In addition, the positioning of the movable blade can be simplified and the cutting function can be easily secured.
