Among these conventional inkjet printers, there is a wiper blade fixed type in which a wiper blade is always installed at an ink wiping position, and the ink ejection surface is wiped each time the inkjet head is reciprocated.
[0004]
However, in such a wiper blade fixed type, since the ink wiping operation is performed every time the inkjet head reciprocates, there is a problem such as impairing the durability of the wiper blade. An ink jet printer has been proposed in which a wiper blade is moved up and down with respect to a standby position.
[0005]
For example, in an inkjet printer proposed in JP-A-8-207293 and JP-A-8-224866, a wiper blade is provided with a lever, and the lever is operated by the carriage by reciprocating movement of the carriage. It is configured to move up and down.
[0006]
In addition, the ink jet printer proposed in Japanese Patent Laid-Open No. 7-52396 is provided with a dedicated cam mechanism for raising and lowering the wiper blade, and the driving force of the line feed motor is transmitted to this cam mechanism to raise and lower the wiper blade. It is the composition which makes it.
[0007]
[Problems to be solved by the invention]
However, in the prior art ink jet printer that raises and lowers the wiper blade by reciprocating the carriage, it is necessary to provide a lever for raising and lowering the wiper blade, and the structure of the wiper blade and its raising and lowering mechanism becomes complicated and the number of parts increases. There is a problem. Further, since the load applied to the carriage motor is increased, there is a problem that the motor torque of the carriage motor is increased.
[0008]
In addition, in the conventional technology in which the dedicated cam mechanism is driven by the line feed motor to raise and lower the wiper blade, the structure of the wiper blade and the lifting mechanism is complicated by the dedicated cam mechanism, and the number of parts increases. There's a problem.
[0009]
Therefore, an object of the present invention is to enable the wiper blade to be raised and lowered with a simple mechanism without causing an increase in motor torque of the carriage motor.

Accordingly, during the rotation of the maintenance cam 45, the caps 35 and 37 move from the lowered position to the raised position and return to the lowered position again along with the rocking movement of the cap drive lever 67. Will be executed. The ink suction described above is performed while the caps 35 and 37 are moved to the raised position.
[0023]
As shown in FIGS. 4 and 5, a wiper blade 69 is disposed on the left side of the cap 35 to remove ink attached to the ink ejection surfaces of the inkjet heads 13 and 15. The wiper blade 69 is raised from the lowered position to the raised position by pushing up the blade holder 71 when the cap drive lever 67 is raised.
[0024]
Further, as shown in FIGS. 4 and 5, the cap drive lever 67 is provided with a stopper 73 disposed between the caps 35 and 37 for positioning the carriage 11.
[0025]
Next, the raising and lowering operations of the caps 35 and 37, the wiper blade 69, and the stopper 73 will be described with reference to FIG. 7A and 7B show a state in which the caps 35 and 37, the wiper blade 69, and the stopper 73 are in the lowered position. In this state, the wiper push-up arm 75 as the wiper moving member or the wiper raising member provided on the cap drive lever 67 is not in contact with the blade holder 71.
[0026]
When the maintenance cam 45 starts to rotate, as shown in FIG. 7C, the cap drive lever 67 starts to rise, and the caps 35 and 37 and the stopper 73 rise together. Further, as shown in FIG. 7D, the wiper push-up arm 75 comes into contact with the bottom surface of the blade holder 71 along with this upward movement. As the maintenance cam 45 further rotates, the caps 35 and 37 and the stopper 73 are further raised and the wiper blade 69 is pushed up by the wiper push-up arm 75 as shown in FIGS. 7 (E) and 7 (F). To the ascending position.
[0027]
Next, the raising and lowering operations of the caps 35 and 37, the wiper blade 69, and the stopper 73 for purging the left inkjet head 13 and the control operation of the carriage 11 will be described with reference to FIGS. First, prior to the purge operation, the carriage 11 is moved to a position near the caps 35 and 37 as indicated by an arrow in FIG. Subsequently, the caps 35, 37 and the like are raised as shown by arrows in FIG. Then, as shown by an arrow in FIG. 9A, when the stopper 73 is raised to a predetermined position, the carriage 11 is further moved to the right, and as shown in FIG. The head 13 is brought into contact. In this state, the caps 35, 37 and the like are further raised as indicated by arrows.
[0028]
Thereafter, as shown in FIG. 10 (A), the caps 35, 37 and the like are raised to the most raised position, whereby the ink discharge surfaces of the inkjet heads 13, 15 are sealed with the caps 35, 37. In this state, as described above, the ink suction operation by the suction pump 51 is performed, and the purge operation for the left inkjet head 13 is performed.
[0029]
After the purge operation is performed in this manner, the maintenance cam 41 continues to rotate, whereby the caps 35, 37, etc. start to descend, and the caps 35, 37 and the stopper 73 are moved to the initial position as shown in FIG. And descend. At this time, the wiper blade 69 starts to descend together with the cap 35 and the like by being pulled diagonally downward to the left by a biasing means attached to the blade holder 71 or a coil spring 77 as a pulling member. However, the blade holder 71 stops descending at a position where the minute protrusion 79 provided on the left side surface thereof abuts against the upper surface of the cradle 81. As a result, as shown in the drawing, only the wiper blade 69 remains in the raised state without returning to the initial position.
[0030]
In this state, the carriage 11 is moved leftward as indicated by an arrow in FIG. As a result, wiping of the ink 83 remaining on the ink ejection surface of the left inkjet head 13 is started by the wiper blade 69 maintained in the raised state by the cradle 81. However, in this ink wiping operation, as shown in FIG. 11A, before the ink discharge surface of the inkjet head 13 is completely wiped, the carriage 11 is stopped when it has moved to the left by a predetermined amount. As a result, the wiper blade 69 bent by the ink wiping operation remains in contact with the ink ejection surface of the inkjet head 13 while maintaining the bending. Therefore, the ink 83 wiped off by the wiper blade 69 falls down along the surface of the wiper blade 69 and is prevented from scattering to the surroundings.
[0031]
Thereafter, as indicated by an arrow in FIG. 11A, the carriage 11 is moved rightward. By this operation, the blade holder 71 that has been kept in the raised state by the action of the minute protrusion 79 and the cradle 81 is pushed rightward by the inkjet head 13 together with the wiper blade 69, and the minute protrusion 79 is removed from the cradle 81.

[0032]
Next, a purge operation for the right inkjet head 15 will be described with reference to FIGS. Also in this case, first, prior to the purge operation, the carriage 11 is moved to a position in the vicinity of the caps 35 and 37 as shown in FIGS. Subsequently, as shown by the arrow in FIG. Then, as shown in FIG. 13A, when the stopper 73 is raised to a predetermined position, the carriage 11 is further moved in the right direction, and as shown in FIG. 15 is brought into contact. In this state, the caps 35, 37, etc. are further raised.
[0033]
Thereafter, as shown in FIG. 14A, the caps 35, 37 and the like are raised to the most raised position, whereby the ink ejection surface of the right inkjet head 15 is sealed with the cap 35. In this state, as described above, the ink suction operation by the suction pump 51 is performed, and the purge operation for the right inkjet head 15 is performed.
[0034]
After the purge operation is performed in this manner, the maintenance cam 41 is subsequently rotated, whereby the caps 35, 37 and the like start to descend, and as shown in FIG. 14B, the caps 35, 37 and the stopper 73 are moved to the initial positions. And descend. At this time, the wiper blade 69 stops descending at a position where the minute projection 79 provided on the left side surface of the blade holder 71 contacts the upper surface of the cradle 81. As a result, as shown in the drawing, only the wiper blade 69 remains in the raised state without returning to the initial position.
[0035]
In this state, the carriage 11 is moved leftward as indicated by an arrow in FIG. As a result, wiping of the ink 83 remaining on the ink ejection surface of the right inkjet head 15 is started by the wiper blade 69 maintained in the raised state by the cradle 81. Also in this ink wiping operation, as shown in FIG. 15A, before the ink discharge surface of the inkjet head 15 is completely wiped, the carriage 11 is stopped when it has moved to the left by a predetermined amount. As a result, the wiper blade 69 bent by the ink wiping operation remains in contact with the ink ejection surface of the inkjet head 15 while maintaining the bending. Therefore, the ink 83 wiped off by the wiper blade 69 falls down along the surface of the wiper blade 69 and is prevented from scattering to the surroundings.
[0036]
Thereafter, as indicated by an arrow in FIG. 15A, the carriage 11 is moved rightward. By this operation, the blade holder 71 that has been kept in the raised state by the action of the minute protrusion 79 and the cradle 81 is pushed rightward by the inkjet head 15 together with the wiper blade 69, and the minute protrusion 79 is removed from the cradle 81. Is done. At this time, since the blade holder 71 is pulled obliquely downward by the coil spring 77, the blade holder 71 is lowered to the initial position again as shown in FIG.
[0037]
As described above, according to the portable printer 1 of the present embodiment, the wiper blade 69 rotates the maintenance cam 41 by the line feed motor 23, so that the wiper push-up arm provided on the cap drive lever 67 is provided. 75, and is stopped at the raised position by the action of the coil spring 77, the minute projection 79, and the cradle 81. Then, when the wiper blade 69 is pushed rightward by the rightward movement of the carriage 11, the minute projection 79 is removed from the upper surface of the receiving base 81 and is lowered to the initial position by the pulling force of the coil spring 77. Yes. As a result, a special drive source for raising and lowering the wiper blade 69 is not required, and the raising and lowering can be realized by a simple mechanism.
[0038]
Further, according to the portable printer 1 of the present embodiment, the carriage 11 before the ink discharge surface is completely wiped by the wiper blade 69 in the wiping operation of the ink discharge surface of the inkjet heads 13 and 15 after the purge operation. Has stopped moving to the left. As a result, the ink 83 does not fall down along the wiper blade 69 bent by the wiping operation of the ink discharge surface, and is not scattered around by the elastic return of the wiper blade 69. As a result, the ink wiping operation after the purging operation does not cause the ink 83 to scatter around and stain the inside of the printer or the printing paper PP. In particular, in this embodiment, since the inkjet heads 13 and 15 are positioned by the stopper 73 during the purge operation of the inkjet heads 13 and 15, the ink discharge surface is completely wiped off in the ink wiping operation by the wiper blade 69. Before, the operation of moving the carriage 11 to the left by a predetermined amount and stopping it can be accurately executed.
[0039]
Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and it is needless to say that various forms can be adopted without departing from the scope of the present invention. .
[0040]
【The invention's effect】
As described above, according to the ink jet printer of the present invention, the wiper blade can be raised and lowered with a simple mechanism without causing an increase in motor torque of the carriage motor.
[0041]
In particular, according to the ink jet printer of claim 3, the wiper blade can be moved to the ink wiping position (wiping position) by the line feed (LF) motor and returned to the initial position by the carriage (CR) motor. Therefore, by effectively using the motor provided in the ink jet printer, the wiper blade lifting mechanism can be simplified, and the wiper blade can be moved to the ink wiping position and returned to the initial position. Since these are performed by the action of separate motors, they have a simpler mechanism and lower torque for each of the LF and CR motors than the conventional ink jet printer that performs the actions of one motor. Can achieve the purpose.
