Description

印刷装置及び印刷用カセットPrinting equipment and cassettes for printing
　本開示は、印刷装置及び印刷用カセットに関する。 This disclosure relates to a printing apparatus and a printing cassette.
　テープに印刷を行う装置では、テープを収納したカセットを本体に着脱することで、テープの交換及び供給が行われる。このような装置に用いられるカセットとして、駆動力が入力される入力ギアと、駆動力を出力する出力ギアとを設けたものが知られている（特許文献１参照）。 In a device that prints on tape, the tape is replaced and supplied by attaching and detaching the cassette containing the tape to and from the main body.

　上述のカセットにおいて、入力ギアの回転速度と出力ギアの回転速度とを変えるためには、減速又は増速を行う伝達機構がカセット内に必要となる。しかし、伝達機構の配置によっては、カセットが大型化するおそれがある。 In the above-mentioned cassette, in order to change the rotation speed of the input gear and the rotation speed of the output gear, a transmission mechanism for decelerating or increasing the speed is required in the cassette. However, depending on the arrangement of the transmission mechanism, the cassette may become large.
　本開示の一局面は、カセットの大型化を抑制しつつ、入力ギアと出力ギアとの回転速度を変更できる印刷装置及び印刷用カセットを提供することを目的とする。 One aspect of the present disclosure is to provide a printing device and a printing cassette capable of changing the rotation speed of an input gear and an output gear while suppressing an increase in the size of the cassette.
　本開示の一態様は、印刷装置本体と、印刷装置本体に着脱可能な印刷用カセットと、を備える印刷装置である。印刷用カセットは、幅方向に離れた第１端と第２端とを有する印刷用テープと、印刷用テープが排出される排出口を有するケースと、外部に駆動力を出力するための出力ギアと、出力ギアと係合するアイドルギアと、アイドルギアに直接又は間接的に係合し、駆動力を出力ギアに伝達する入力ギアと、を備える。 One aspect of the present disclosure is a printing device including a printing device main body and a printing cassette that can be attached to and detached from the printing device main body. The printing cassette includes a printing tape having a first end and a second end separated in the width direction, a case having an outlet for discharging the printing tape, and an output gear for outputting a driving force to the outside. And an idle gear that engages with the output gear, and an input gear that directly or indirectly engages with the idle gear and transmits a driving force to the output gear.
　出力ギア及びアイドルギアは、それぞれ、排出口における印刷用テープから幅方向において離れた位置で、幅方向において排出口における印刷用テープの第２端よりも第１端の近くの位置に配置される。アイドルギアは、出力ギアに係合する第１ギアと、第１ギアよりも径が大きい第２ギアとが並んで配置された段ギアである。第２ギアは、幅方向において、出力ギアとは異なる位置に配置される。 The output gear and the idle gear are respectively arranged at positions separated from the printing tape at the discharge port in the width direction and closer to the first end than the second end of the printing tape at the discharge port in the width direction. .. The idle gear is a stage gear in which a first gear that engages with an output gear and a second gear having a diameter larger than that of the first gear are arranged side by side. The second gear is arranged at a position different from the output gear in the width direction.
　印刷装置本体は、印刷用テープに印刷するための印刷ヘッドと、印刷ヘッドに対向し、印刷用テープを搬送するためのプラテンローラと、プラテンローラを支持するローラホルダと、プラテンローラに連結され、出力ギアと係合するプラテンギアと、入力ギアに係合し、入力ギアを回転させるための駆動シャフトと、を備える。 The main body of the printing apparatus is connected to a printing head for printing on a printing tape, a platen roller facing the printing head to convey the printing tape, a roller holder for supporting the platen roller, and a platen roller. It includes a platen gear that engages with the output gear and a drive shaft that engages with the input gear and rotates the input gear.
　本開示の別の態様は、幅方向に離れた第１端と第２端とを有する印刷用テープと、印刷用テープが排出される排出口を有するケースと、外部に駆動力を出力するための出力ギアと、出力ギアと係合するアイドルギアと、アイドルギアに直接又は間接的に係合し、駆動力を出力ギアに伝達する入力ギアと、を備える印刷用カセットである。 Another aspect of the present disclosure is to output a driving force to the outside, a printing tape having a first end and a second end separated in the width direction, a case having a discharge port from which the printing tape is discharged, and an outlet. The printing cassette includes an output gear, an idle gear that engages with the output gear, and an input gear that directly or indirectly engages with the idle gear and transmits a driving force to the output gear.
　出力ギア及びアイドルギアは、それぞれ、排出口における印刷用テープから幅方向において離れた位置で、幅方向において排出口における印刷用テープの第２端よりも第１端の近くの位置に配置される。アイドルギアは、出力ギアに係合する第１ギアと、第１ギアよりも径が大きい第２ギアとが並んで配置された段ギアである。第２ギアは、幅方向において、出力ギアとは異なる位置に配置される。 The output gear and the idle gear are respectively arranged at positions separated from the printing tape at the discharge port in the width direction and closer to the first end than the second end of the printing tape at the discharge port in the width direction. .. The idle gear is a stage gear in which a first gear that engages with an output gear and a second gear having a diameter larger than that of the first gear are arranged side by side. The second gear is arranged at a position different from the output gear in the width direction.
　これらのような構成によれば、印刷用テープの幅方向におけるカセット内のスペースを有効活用し、段ギアを配置することができる。その結果、印刷用カセットの大型化を抑制しつつ、入力ギアと出力ギアとの回転速度を変更することができる。 According to these configurations, it is possible to effectively utilize the space in the cassette in the width direction of the printing tape and arrange the step gears. As a result, the rotation speeds of the input gear and the output gear can be changed while suppressing the increase in size of the printing cassette.
　本開示のさらに別の態様は、印刷装置本体に着脱可能な印刷用カセットである。印刷用カセットは、幅方向に離れた第１端と第２端とを有する印刷用テープと、印刷用テープが排出される排出口を有するケースと、外部に駆動力を出力するための出力ギアと、出力ギアと係合するアイドルギアと、アイドルギアに直接又は間接的に係合し、駆動力を出力ギアに伝達する入力ギアと、を備える。 Yet another aspect of the present disclosure is a printing cassette that can be attached to and detached from the printing apparatus main body. The printing cassette includes a printing tape having a first end and a second end separated in the width direction, a case having an outlet for discharging the printing tape, and an output gear for outputting a driving force to the outside. And an idle gear that engages with the output gear, and an input gear that directly or indirectly engages with the idle gear and transmits a driving force to the output gear.
　出力ギア及びアイドルギアは、それぞれ、排出口における印刷用テープから幅方向において離れた位置で、幅方向において排出口における印刷用テープの第２端よりも第１端の近くの位置に配置される。アイドルギアは、第１ギアと、第１ギアよりも径が大きい第２ギアとが並んで配置された段ギアである。 The output gear and the idle gear are respectively arranged at positions separated from the printing tape at the discharge port in the width direction and closer to the first end than the second end of the printing tape at the discharge port in the width direction. .. The idle gear is a step gear in which a first gear and a second gear having a diameter larger than that of the first gear are arranged side by side.
　印刷装置本体は、印刷用テープに印刷するための印刷ヘッドと、印刷ヘッドに対向し、印刷用テープを搬送するためのプラテンローラと、プラテンローラを支持するローラホルダと、プラテンローラに連結され、出力ギアと係合するプラテンギアと、入力ギアに係合し、入力ギアを回転させるための駆動シャフトと、を備える。第２ギアの少なくとも一部は、幅方向において、ローラホルダと同じ位置に配置される。 The main body of the printing apparatus is connected to a printing head for printing on a printing tape, a platen roller facing the printing head to convey the printing tape, a roller holder for supporting the platen roller, and a platen roller. It includes a platen gear that engages with the output gear and a drive shaft that engages with the input gear and rotates the input gear. At least a part of the second gear is arranged at the same position as the roller holder in the width direction.
　このような構成によれば、印刷用テープの幅方向において、伝達機構を構成するアイドルギアの第２ギアを、ローラホルダと重なるように配置することができる。これにより、印刷用テープの幅方向におけるギア列のサイズを低減することができる。その結果、印刷用カセットの大型化を抑制しつつ、入力ギアと出力ギアとの回転速度を変更することができる。 According to such a configuration, the second gear of the idle gear constituting the transmission mechanism can be arranged so as to overlap the roller holder in the width direction of the printing tape. This makes it possible to reduce the size of the gear train in the width direction of the printing tape. As a result, the rotation speeds of the input gear and the output gear can be changed while suppressing the increase in size of the printing cassette.

The gear 19A rotates integrally with the spool 19B by the driving force input to the spool 19B.
　入力ギア１９の回転軸心Ｌ８（つまり、ギア１９Ａの回転軸心及びスプール１９Ｂの回転軸心）は、入力スプール１６の回転軸心Ｌ６と同一線上に配置されている。図４に示すように、入力スプール１６、入力ギア１９の一部（つまり外歯ギア１９Ａ）、及び第１ロール１１は、上下方向において、入力スプール１６、入力ギア１９の一部（つまり外歯ギア１９Ａ）、及び第１ロール１１の順に並んで配置されている。 The rotation axis L8 of the input gear 19 (that is, the rotation axis of the gear 19A and the rotation axis of the spool 19B) is arranged on the same line as the rotation axis L6 of the input spool 16. As shown in FIG. 4, the input spool 16, a part of the input gear 19 (that is, the external tooth gear 19A), and the first roll 11 have a part of the input spool 16 and the input gear 19 (that is, the external tooth) in the vertical direction.

Further, at least a part of the external tooth gear 19A is arranged at a position overlapping with the first roll 11 in the vertical direction.
　入力ギア１９の回転軸心Ｌ８は、上下方向において、入力スプール１６の中空部と重なる。そのため、駆動シャフト１０５が入力スプール１６と入力ギア１９とに同時に挿通される。その結果、入力ギア１９は、入力スプール１６と直接連結はされていないが、入力スプール１６と共通の駆動源（つまり駆動シャフト１０５）によって回転される。 The rotation axis L8 of the input gear 19 overlaps with the hollow portion of the input spool 16 in the vertical direction. Therefore, the drive shaft 105 is inserted into the input spool 16 and the input gear 19 at the same time.

The second gear 20B has a larger diameter than the first gear 20A.
　また、第１ギア２０Ａは、上下方向において、第２ギア２０Ｂよりも第１ロール１１に近い位置（つまり上方）に配置されている。アイドルギア２０は、入力ギア１９に入力された駆動力の回転速度を減速させる減速機構を構成している。 Further, the first gear 20A is arranged at a position closer to the first roll 11 (that is, above) than the second gear 20B in the vertical direction. The idle gear 20 constitutes a reduction mechanism that reduces the rotational speed of the driving force input to the input gear 19.

The print head 102 prints on the printing tape 11A held by the printing cassette 10. The print head 102 is arranged at a position where the printing cassette 10 is mounted on the printing apparatus main body 100 and overlaps with the printing tape 11A and the ink ribbon 14A in the front-rear direction in the head opening 33B (see FIG. 6).
　プラテンローラ１０３によってヘッド開口３３Ｂに搬送された印刷用テープ１１Ａは、インクリボン１４Ａを介して発熱素子が発熱した印刷ヘッド１０２に押し付けられる。これにより、インクリボン１４Ａの表面に配置されたインクの一部が印刷用テープ１１Ａに転写され、印刷用テープ１１Ａに文字、記号等が印刷される。 The printing tape 11A conveyed to the head opening 33B by the platen roller 103 is pressed against the printing head 102 in which the heat generating element generates heat via the ink ribbon 14A. As a result, a part of the ink arranged on the surface of the ink ribbon 14A is transferred to the printing tape 11A, and characters, symbols and the like are printed on the printing tape 11A.
　プラテンローラ１０３は、印刷用テープ１１Ａを印刷用カセット１０内から外部に向けて搬送する。プラテンローラ１０３は、ヘッド開口３３Ｂにおいて印刷用テープ１１Ａに当接し、印刷用テープ１１Ａを印刷ヘッド１０２に押し当てる。 The platen roller 103 conveys the printing tape 11A from the inside of the printing cassette 10 to the outside. The platen roller 103 abuts on the printing tape 11A at the head opening 33B and presses the printing tape 11A against the printing head 102.

The platen roller 103 and the platen gear 104 swing between a position separated from the printing cassette 10 shown in FIG. 8 and a position where the platen gear 104 shown in FIG. 9 engages with the output gear 18 due to the swing of the movable portion 106. It is movable.
　駆動シャフト１０５は、入力スプール１６に挿入されると共に入力ギア１９に係合し、入力スプール１６と入力ギア１９とを回転させる。 The drive shaft 105 is inserted into the input spool 16 and engages with the input gear 19 to rotate the input spool 16 and the input gear 19.
　図９に示すように、印刷用カセット１０が印刷装置本体１００に装着された状態で、駆動シャフト１０５が入力ギア１９に係合すると共にプラテンギア１０４が出力ギア１８に係合する。具体的には、駆動シャフト１０５を印刷用カセット１０の入力スプール１６及び入力ギア１９に挿入する。その後、プラテンローラ１０３及びプラテンギア１０４を印刷用カセット１０のヘッド開口３３Ｂに向けて揺動させる。 As shown in FIG. 9, with the printing cassette 10 mounted on the printing apparatus main body 100, the drive shaft 105 engages with the input gear 19 and the platen gear 104 engages with the output gear 18. Specifically, the drive shaft 105 is inserted into the input spool 16 and the input gear 19 of the printing cassette 10. After that, the platen roller 103 and the platen gear 104 are swung toward the head opening 33B of the printing cassette 10.

　＜印刷用テープ及びギアの配置＞
　図１０Ａ，１０Ｂは、ケース３５のヘッド開口３３Ｂにおける印刷用テープ１１Ａ、ギア列、及びプラテンローラ１０３の配置を示したものである。印刷用テープ１１Ａは、幅方向に離れた第１端１１１と第２端１１２とを有している。 <Arrangement of printing tape and gears>
10A and 10B show the arrangement of the printing tape 11A, the gear train, and the platen roller 103 in the head opening 33B of the case 35. The printing tape 11A has a first end 111 and a second end 112 that are separated in the width direction.
　排出口３３Ｃにおいて、印刷用テープ１１Ａの幅方向は上下方向に一致する。また、排出口３３Ｃにおいて、印刷用テープ１１Ａの第１端１１１は、第２端１１２に対し上方に位置する。 At the discharge port 33C, the width direction of the printing tape 11A coincides with the vertical direction. Further, in the discharge port 33C, the first end 111 of the printing tape 11A is located above the second end 112.
　出力ギア１８及びアイドルギア２０は、それぞれ、排出口３３Ｃにおける印刷用テープ１１Ａから幅方向（つまり上下方向）において離れた位置で、幅方向において排出口３３Ｃにおける印刷用テープ１１Ａの第２端１１２よりも第１端１１１の近くの位置に配置されている。 The output gear 18 and the idle gear 20 are located at positions separated from the printing tape 11A at the discharge port 33C in the width direction (that is, in the vertical direction), respectively, from the second end 112 of the printing tape 11A at the discharge port 33C in the width direction. Is also located near the first end 111.
　つまり、出力ギア１８及びアイドルギア２０は、それぞれ、ヘッド開口３３Ｂ内の印刷用テープ１１Ａよりも上方に位置している。したがって、出力ギア１８及びアイドルギア２０は、前後方向において印刷用テープ１１Ａとは重ならない位置に配置されている。 That is, the output gear 18 and the idle gear 20 are located above the printing tape 11A in the head opening 33B, respectively. Therefore, the output gear 18 and the idle gear 20 are arranged at positions that do not overlap with the printing tape 11A in the front-rear direction.
　また、アイドルギア２０の第２ギア２０Ｂは、排出口３３Ｃにおける印刷用テープ１１Ａの幅方向において、出力ギア１８とは異なる位置に配置されている。具体的には、第２ギア２０Ｂは、出力ギア１８よりも下方に位置している。 Further, the second gear 20B of the idle gear 20 is arranged at a position different from that of the output gear 18 in the width direction of the printing tape 11A at the discharge port 33C. Specifically, the second gear 20B is located below the output gear 18.
　したがって、排出口３３Ｃにおける印刷用テープ１１Ａ、第２ギア２０Ｂ、及び出力ギア１８は、印刷用テープ１１Ａの幅方向において、排出口３３Ｃにおける印刷用テープ１１Ａ、第２ギア２０Ｂ、及び出力ギア１８の順に並んで配置されている。 Therefore, the printing tape 11A, the second gear 20B, and the output gear 18 at the discharge port 33C are the printing tape 11A, the second gear 20B, and the output gear 18 at the discharge port 33C in the width direction of the printing tape 11A. They are arranged side by side in order.
　さらに、第２ギア２０Ｂの少なくとも一部は、排出口３３Ｃにおける印刷用テープ１１Ａの幅方向において、第１ローラホルダ１０３Ａと同じ位置に配置されている。つまり、第２ギア２０Ｂは、左右方向において第１ローラホルダ１０３Ａと重なる位置に配置されている。 Further, at least a part of the second gear 20B is arranged at the same position as the first roller holder 103A in the width direction of the printing tape 11A at the discharge port 33C. That is, the second gear 20B is arranged at a position overlapping the first roller holder 103A in the left-right direction.
　第２ギア２０Ｂの一部（具体的には、歯先部分）は、排出口３３Ｃにおける印刷用テープ１１Ａの幅方向において、出力ギア１８と重なっている。また、第２ギア２０Ｂは、排出口３３Ｃにおける印刷用テープ１１Ａの幅方向において、出力ギア１８の回転軸心Ｌ７とは重なっていない。 A part of the second gear 20B (specifically, the tooth tip portion) overlaps with the output gear 18 in the width direction of the printing tape 11A at the discharge port 33C. Further, the second gear 20B does not overlap with the rotation axis L7 of the output gear 18 in the width direction of the printing tape 11A at the discharge port 33C.

According to the embodiment described in detail above, the following effects can be obtained.
(1a) In the printing apparatus 1, there is a space from the upper end of the printing tape 11A to the upper end of the first roller holder 103A, which is an area that cannot be used for printing in the tape width direction. According to the present embodiment, in the width direction of the printing tape 11A, the second gear 20B of the idle gear 20 constituting the transmission mechanism can be arranged in the space.
　これにより、印刷用テープ１１Ａの幅方向における印刷用カセット１０内のスペースを有効活用することができる。その結果、印刷用カセット１０の大型化を抑制しつつ、入力ギア１９と出力ギア１８との回転速度を変更することができる。 Thereby, the space in the printing cassette 10 in the width direction of the printing tape 11A can be effectively utilized. As a result, the rotation speeds of the input gear 19 and the output gear 18 can be changed while suppressing the increase in size of the printing cassette 10.
　（１ｂ）また、第２ギア２０Ｂの少なくとも一部が印刷用テープ１１Ａの幅方向において第１ローラホルダ１０３Ａと同じ位置に配置されることで、ギア列の上下方向におけるサイズ（つまり幅）を低減できる。 (1b) Further, at least a part of the second gear 20B is arranged at the same position as the first roller holder 103A in the width direction of the printing tape 11A, thereby reducing the size (that is, the width) of the gear row in the vertical direction. it can.
　（１ｃ）第２ギア２０Ｂの一部が印刷用テープ１１Ａの幅方向において出力ギア１８と重なることで、上下方向と垂直な方向（つまり左右方向及び前後方向）におけるギア列のサイズも低減できる。 (1c) By overlapping a part of the second gear 20B with the output gear 18 in the width direction of the printing tape 11A, the size of the gear row in the direction perpendicular to the vertical direction (that is, the horizontal direction and the front-rear direction) can also be reduced.
　（１ｄ）第２ギア２０Ｂが出力ギア１８の回転軸心Ｌ７と重ならないことで、ギア列のサイズを低減しつつ、出力ギア１８を支持する第１ギア支持部３２Ｄの配置の自由度を高めることができる。 (1d) Since the second gear 20B does not overlap with the rotation axis L7 of the output gear 18, the size of the gear train is reduced and the degree of freedom in the arrangement of the first gear support portion 32D that supports the output gear 18 is increased. be able to.
