At first, see also the 3rd figure and 4A figure, first sliding part 121 meeting originally of residual black removing device 100 is a left position at pedestal 110 because of the pulling force of elastic parts 170.When the ink cartridges carrier 32 that carries ink cartridges 31 moved right the top of to ink jet head maintenance station 34 (residual black removing device 100), the location division 161 of reference column 160 can be sticked in ink cartridges carrier 32 earlier.Then, ink cartridges carrier 32 continues to move to the right, at this moment, the 3rd sliding part 162 of reference column 160 can slide among the 3rd saturating groove 112 of pedestal 110 because of the drive of ink cartridges carrier 32, and base 120 also can be driven and be displaced on the pedestal 110 by ink cartridges carrier 32 because of reference column 160, at this, first sliding part 121 of base 120 can slide among the first saturating groove 111 of pedestal 110, and two second sliding parts 132 of wiping seat 130 also can be because base 120 moves right slip among the 4th saturating groove 113 of the second saturating groove 122 of base 120 and pedestal 110 simultaneously.Shown in Fig. 5 B, owing to have a horizontal sextant angle θ between the 4th saturating groove 113 and the second saturating groove 122, wiping seat 130 and wiper 131 can relatively move scaler 150 by the guiding of the 4th saturating groove 113 and the second saturating groove 122 simultaneously.Particularly, because the location division 161 of reference column 160 is to be sticked in ink cartridges carrier 32, so ink cartridges carrier 32 is in the process that moves right, ink cartridges 31 (ink gun 33) can stay in the top of base 120, and wiper 131 can slide on the ink gun 33 with the residual ink on the wiping ink gun 33 earlier, wiper 131 can slide into scaler 150 places more then, and strike off residual ink on the wiper 131 by scaler 150, as Fig. 8 A, Fig. 8 B, Fig. 9 A, Fig. 9 B, shown in Fig. 9 C and Fig. 9 D (at this, Fig. 9 A, Fig. 9 B, Fig. 9 C, Fig. 9 D and Fig. 4 A are in identical visual angle).In addition, shown in Fig. 8 B, strike off in the process of the residual ink on the wiper 131 at scaler 150, scaler 150 is understood by wiper 131 jack-up, and only can turn to the second place, and this is because the rotational angle of scaler 150 has been limited in second blocking part 142.

On the other hand, when the ink cartridges carrier 32 that carries ink cartridges 31 was back mobile left from ink jet head maintenance station 34, wiper 131 can slide and break away from scaler 150, shown in Fig. 8 A.At this moment, scaler 150 can return back to primary importance because of the effect of gravity or torque spring 180, and this is because the rotational angle of scaler 150 has been limited in first blocking part 141.Then, the 3rd sliding part 162 of reference column 160 can slide on left among the 3rd saturating groove 112 of pedestal 110, and base 120 also can be driven and be moved to the left on pedestal 110 by ink cartridges carrier 32 because of reference column 160.At this moment, first sliding part 121 of base 120 can slide among the first saturating groove 111 of pedestal 110 in reverse direction, and two second sliding parts 132 of wiping seat 130 also can be because base 120 is moved to the left the while slide among two the second saturating grooves 122 of base 120 in reverse direction and among two the 4th saturating grooves 113 of pedestal 110.Similarly, in wiper 131 slided the process of returning, wiper 131 can slide on ink gun 33 once more, with the residual ink on the wiping ink gun 33 once more.It should be noted that, when the 3rd sliding part 162 of reference column 160 slides into the horizontal component of the 3rd saturating groove 112, two elastic parts 170 that are connected in 121 of first sliding parts of pedestal 110 and base 120 also can be brought into play extra elastic-restoring force effect, so that base 120 can more successfully move left or back.

As mentioned above, when ink-jet output device 3 will carry out the cleaning of its ink gun 33, only need make the move right top of to ink jet head maintenance station 34 (residual black removing device 100) of the ink cartridges carrier 32 that carries ink cartridges 31, the purpose that can reach the residual ink on the wiping ink gun 33 simultaneously and strike off the residual ink on the wiper 131.

In addition, more noticeablely be, residual black removing device 100 of the present invention is not limited to have rotating scaler 150 and is fixed on wiper 131 on the wiping seat 130, in other words, scaler 150 also can be to be fixed on the rotating seat 140, and wiper 131 then is to be arranged on the wiping seat 130 in rotating mode.Therefore, when wiping seat 130 moved to scaler 150 places, wiper 131 can rotate because of keeping out of scaler 150, and the residual ink on the wiper 131 still can be struck off by scaler 150 then.

Though disclosed the present invention in conjunction with above preferred embodiment; yet it is not in order to limiting the present invention, anyly is familiar with this operator, without departing from the spirit and scope of the present invention; when the change that can do some and retouching, so protection scope of the present invention should be with being as the criterion that claim was defined.
