Ink-jet printer shown in Figure 1 (printer, media conveying mechanism) 1 has platen 11, conveying roller (transfer unit, roller) 12, at least two alignment pins (abutting part) 13, press section (pressing component) 14 and ink gun 15.Wherein, the function of platen 11, conveying roller 12, alignment pin 13 and press section 14 performance pumped (conveying) mediums.
In ink-jet printer 1, along throughput direction (direction shown in the arrow A) pumped (conveying) medium 50, and adjust the inclination of this medium 50.So-called " inclination of medium 50 " refers to that medium 50 is with respect to the inclination in the horizontal plane of throughput direction.
Medium 50 is the objects that are transferred, and this medium 50 has the top ends 50a with the throughput direction quadrature in the situation that medium 50 does not tilt.At this, although be that the situation that is printed object (such as paper, Corvic etc.) describes to medium 50, be not limited thereto.Medium among the present invention also can be plastics, glass such as sheet etc.
Conveying roller 12 is by being rotated the roller of pumped (conveying) medium 50.Preferably, conveying roller 12 is carried this medium 50 under the prerequisite that does not hinder medium 50 action in the horizontal direction.So-called " horizontal direction " refers to the whole directions on the horizontal plane.The concept of " action of the horizontal direction of medium 50 " comprise medium 50 along the whole directions on the horizontal plane move, the action such as rotation and action that movement, rotation etc. are stopped.That is, 50 apply in the situation of power of the action that promotes horizontal direction from the outside to medium at conveying roller 12, can not hinder medium 50 to stop movement towards throughput direction, or the direction beyond throughput direction moves.As the power that applies to medium 50 from the outside, for example can list in the situation of medium 50 and alignment pin 13 butts the power of bearing from alignment pin 13 etc.
In addition, conveying roller 12 do not hinder with alignment pin 13 in the prerequisite of the medium 50 of at least one butt action of rotating as the fulcrum along continuous straight runs with this alignment pin 13 under, continue to carry this medium 50, until this medium 50 and whole alignment pin 13 butts.In other words, because therefore at least 1 butt in medium 50 and the alignment pin 13 makes after the action of throughput direction stops, conveying roller 12 also is continuously applied the power of wanting to throughput direction pumped (conveying) medium 50.
Specifically, because at least 1 butt in medium 50 and the alignment pin 13, therefore stop from the power of the alignment pin 13 of institute's butt in the situation of the movement of throughput direction even bear at medium 50, conveying roller 12 also on one side and medium 50 slide (skidding) continue rotation on one side.That is, conveying roller 12 constitute can and medium 50 between skid.Thus, medium 50 bears simultaneously from the wish of conveying roller 12 and carries the power of this medium 50 and overcome the power from alignment pin 13 of this power.
At this, carry in the situation of this medium 50 the top ends 50a of medium 50 and throughput direction quadrature at the state that does not tilt with medium 50.The top ends 50a of the medium 50 of therefore, being carried by conveying roller 12 simultaneously and whole alignment pin 13 butts.Consequently, carry the power of this medium 50 and the power from whole alignment pins 13 that overcomes this power to balance each other owing to act on the wish from conveying roller 12 of medium 50, therefore, medium 50 stops action.
On the other hand, carrying in the situation of this medium 50 at the state that tilts with medium 50, the top ends 50a of medium 50 not with the throughput direction quadrature.The top ends 50a of the medium 50 of therefore, being carried by conveying roller 12 at first with any alignment pin 13 butts.Afterwards, since medium 50 bear simultaneously from the wish of conveying roller 12 carry this medium 50 power and with the power from the alignment pin 13 of institute's butt that overcomes this power, thus, this medium 50 bears the power that top ends 50a is rotated in the mode with the throughput direction quadrature.Thus, before top ends 50a and whole alignment pin 13 butts, be top ends 50a and throughput direction quadrature before, medium 50 rotates at horizontal plane.
