To the operation of said structure be described below.
In the process that prints on recording medium P, carriage 107 moves with the axis of guide 103 and the axis of guide 105, and prints on recording medium P.The motion of advancing of carriage 107 relates to the rotation of the pinion 403 that meshes with tooth bar 401.The rotation of pinion 403 passes to central gear 413 by first helical gear 407, second helical gear 409, first gear 405 and second gear 411.
When the direct of travel of carriage 107 be by Fig. 8 in during direction shown in the arrow I (thick-line arrow), central gear 413 rotates counterclockwise.When the direct of travel of carriage 107 be by Fig. 8 in during direction shown in the arrow II (thin-line arrow), central gear 413 clockwise rotates.When central gear 413 rotated, first planetary gear 451 and second planetary gear 453 in the planetary gears also rotated.In addition, retainer 421 rotates with central gear 413.
As shown in Figure 8, if central gear 413 is along being rotated by the direction shown in the thick-line arrow, then retainer 421 is also along being rotated by the direction shown in its thick-line arrow, and second planetary gear 453 and idler gear 463 engagements.Then, idler gear 463 and winding gear 461 are along being rotated by the direction shown in the thin-line arrow.Retainer 421 stops operating during with idler gear 463 engagements at second planetary gear 453, thus the projection 425 of retainer 421 and 427 and the inwall CONTACT WITH FRICTION of the circular recessed portion 417 of central gear 413.
Simultaneously, if central gear 413 is along being rotated by the direction shown in the thin-line arrow, then retainer 421 is also along being rotated by the direction shown in its thin-line arrow, and first planetary gear 451 and winding gear 461 engagements.Then, winding gear 461 is along being rotated by the direction shown in the thick-line arrow.Retainer 421 stops operating when first planetary gear 451 meshes with winding gear 461, thus the inwall CONTACT WITH FRICTION of the circular recessed portion 417 of the projection of retainer 421 425 and projection 427 and central gear 413.
The rotation direction of winding gear 461 is identical, though carriage 107 along by the direction shown in the arrow I (thick-line arrow) motion or carriage 107 along moving by the direction shown in the arrow II (thin-line arrow).
