- the size in the thickness direction of the gear in the cartridge mounting portion 212 is increased, but the increased width is as small as the thickness of the output gear 331. Moreover, since it extends to the position corresponding to the empty space of the time recorder 10 from the beginning, there is no problem with the downsizing of the time recorder 10.
- the moving gear is disposed so as to protrude from two gears meshed with the moving gear on its parallel surface so as to mesh with the rack.
- the ribbon take-up unit 30 is a small piece that does not protrude from the two gears (the first moving gear 31 and the second moving gear 34) that directly mesh with the ribbon take-up rack 300 on its parallel surface. Only a certain spacer 360 is arranged. For this reason, the cartridge mounting part 212 can be made small by the space.

In such a case, torque is not transmitted to the take-up shaft 332, and the ink ribbon cannot be taken up. In this case, there is a problem that printing is not performed on the printing paper, but the user can grasp that the problem has occurred and can perform a repair work of removing the foreign matter. Even in such a case, an unreasonable load does not occur in the meshing relationship between the first moving gear 31 and the intermediate gear 32, and the second moving gear 34 and the reverse gear 35. None do.
- the first moving gear 31 and the second moving gear 34 are directly meshed with the ribbon winding rack 300. For this reason, the first moving gear 31 and the second moving gear 34 abut on the ribbon take-up rack 300 and rotate, and the take-up shaft 332 of the take-up member 33 is interposed via the intermediate gear 32 (the reverse gear 35).

That is, since the extra moving gear is not provided, the cartridge mounting portion 212, the carriage 210, and the time recorder 10 can be made compact.
- the ribbon winding unit 30 includes a two-stage gear including a first moving gear 31 formed in a hollow shape, a large gear 320 that meshes with the first moving gear 31 and the reverse gear 35, and a small gear 322. And a winding member 33 having an intermediate gear 32, an output gear 331 that meshes with the small gear 322, and a winding shaft 332 that is inserted (penetrated) through the first moving gear 31.
- the ribbon winding unit 30 is compact in the radial direction of each gear.
- the ribbon take-up unit 30 has an appropriate torque (and rotational speed) for taking up the ink ribbon even if the size is compact by adjusting the gear ratio of the gears engaged with each other. It becomes.
- the magnitude relationship of the gear in this embodiment is an example, and does not specifically limit the invention.
- the first gear 31 and / or the second gear 34 is used as a two-stage gear, and the gear ratio with the intermediate gear 32 and / or the reverse gear 35 is adjusted. You may make it do. With such a configuration, the size of the first moving gear 31 and / or the second moving gear 34 in the radial direction is compact.

前記第1中間歯車に噛合し、前記第1及び第2移動歯車が前記キャリッジ内において前記逆方向に移動したときに前記第2移動歯車に噛合し、前記第1及び第2移動歯車が前記キャリッジ内において前記一方向に移動したときに前記第2移動歯車との噛合が解除される第2中間歯車と、
前記巻取軸と、該巻取軸と同軸上に形成され前記第1中間歯車に噛合する出力歯車と、を有する巻取部材と、
を備える、
ことを特徴とする。
前記第1中間歯車は、前記第1移動歯車に噛合する第1歯車、及び第2歯車を有する二段歯車であり、
前記出力歯車は、前記第2歯車に噛合し、
前記巻取部材は、前記巻取軸が前記第1移動歯車を挿通するように配置されていると好ましい。
前記第2移動歯車は、前記ラックに噛合する第5歯車と該第5歯車と同軸上に形成され前記第2中間歯車に噛合する第6歯車とを有する二段歯車であると好ましい。
前記スペーサは、前記第1移動歯車及び第2移動歯車の前記フランジ部の双方に当接可能な位置に配置されていると好ましい。
次に、キャリッジ210の移動方向に応じたリボン巻取部30の動作について図5A,5B及び図6A,6Bを参照して説明する。なお、図5A,5Bに示されたブロック矢印は、カートリッジ装着部212(キャリッジ210)の移動方向を示すものである。図6A,6Bに示されたブロック矢印は、第1移動歯車31及び第2移動歯車34のカートリッジ装着部212(キャリッジ210)内における移動方向を示すものである。また、円弧状の矢印は、巻取軸332の回転に寄与する歯車の回転方向を示すものである。
つまり、余分な移動歯車が設けられていない分、カートリッジ装着部212、キャリッジ210、延いてはタイムレコーダ10をコンパクトにできる。
