2. Description of the Related Art Conventionally, there is an ink jet recording apparatus which performs recording by discharging ink from nozzles. In the ink jet recording apparatus, since the ink on the nozzle surface dries and solidifies and ink discharge failure easily occurs, it is necessary to cap the ink jet head when not in use. Further, when an ink ejection failure occurs, or in order to prevent the ink ejection failure, maintenance of the inkjet head is performed. For example, the maintenance operation includes purging to eliminate clogging in the nozzles by sucking dry ink from the nozzles of the inkjet head, and wiping the nozzle surface wet with ink (wiping).
There is. When the above-described operation is performed manually by the maintenance device that performs maintenance of various heads as described above, the operation is naturally complicated.

Two downward jet nozzles (not shown) are provided in two rows in the left-right direction orthogonal to the recording direction. That is, the ink in the ink tank 15 is supplied to each ejection nozzle of the recording head 2, and ink droplets are selectively ejected from the plurality of ejection nozzles toward the lower recording paper 11. It has become.

The moving amount detecting mechanism 4 detects a relative moving amount of the recording apparatus 1 with respect to the recording paper 11.
At the lower end of the main body case 10, adjacent to the recording head 2,
A rubber timing roller 21 extending in the left-right direction is rotatably supported by a pivot 22. On the other hand, a gear 23 in contact with a part of the timing roller 21 is rotatably connected to the main body case 10, and a circular encoder plate 24 driven to rotate by the gear 23 is rotatably connected to the body case 10. ing.

That is, by manually moving the main body case 10 in the recording direction while the timing roller 21 is in contact with the recording paper 11, the timing roller 21 rotates in a predetermined rotation direction (clockwise direction in FIG. 2). At the same time, when the encoder plate 24 is rotated via the gear 23,
Based on an encoder signal (corresponding to a movement amount signal) composed of a pulse train output from the photo sensor 25 and the recording data, a plurality of ejection nozzles are used at each recording timing at which the main body case 10 moves by a predetermined recording pitch. Inks are selectively ejected, and characters and images are recorded on the recording paper 11.

Next, a description will be given of a maintenance apparatus to which the above-described recording apparatus 1 is attached and which performs maintenance. 3 is an external view of the maintenance device according to the first embodiment, FIG. 4 is a sectional view thereof, and FIG. 5 is a side sectional view. The maintenance device 30 has a case 31 having an open upper surface, and a cap 32 (covering means) that covers the recording head 2.
And a suction pump 33 for purging ink from the nozzles of the recording head 2 and a wipe rubber 37 (wiping means) for wiping the nozzle surface of the head 2. The cap 32 and the suction pump 33 are connected by a suction tube 34. The cap 32 is vertically movable and is urged upward by a compression spring 35.
In addition, the cap 32 is provided with a protrusion 36 for the vertical movement operation. The wipe rubber 37 is the case 31

A battery 41 is mounted as a driving power supply for the suction pump 33, and the suction operation is performed by operating an operation switch (not shown).

The cap 32 is made of elastic rubber and has a block shape slightly larger than the head surface (lower end surface) of the recording head 2. Thus, a suction recess is formed. The suction pump 33 generates a suction negative pressure by a cam body that is rotationally driven by a small motor driven by a battery 41. The negative pressure causes the suction tube 34 and the suction concave portion of the cap 32 to be generated. A plurality of injection nozzles are sucked through. The wipe rubber 37 is made of rubber having elasticity, and wipes a nozzle portion wet with ink after sucking ink from the ejection nozzle of the recording head 2. The compression spring 35 acts so that the cap 32 comes into close contact with the recording head 2 when the recording head 2 sucks the ink, and the cap 32 retreats from the recording head 2 when the recording head 2 is wiped. 2 acts so as to be in close contact with the cap 32.

Further, when the operation lever 40 of the slide mechanism is moved horizontally, the engagement between the projection 36 and the projection of the cam 39 is terminated, the cap 32 moves upward by the restoring force of the compression spring 35, and the recording head is again moved. Close contact with 2. In the next wiping, the operation lever 40 of the slide mechanism is horizontally moved in a direction opposite to the previous direction. Thus, the cap 32 can be separated from the recording head 2 and wiping can be performed by operating the lever in one direction.

13: YES). Then, based on the recording data of one dot row, the corresponding ejection nozzle is driven to execute ink ejection, and the recording processing of one dot row is performed (S1).
6). Next, the print instruction switch 13 is ON (S1).
7: YES), when the encoder signal is further input, that is, when the manual movement of the main body case 10 is continued (S18: YES), and when the recording process is not completed (S19: NO), S16 to S19 are repeatedly executed, and the recording process for each dot row is executed.

When the printing process for one line is completed (S19: YES), S17 to S19 are repeated. At this time, when the movement of the main body case 10 is stopped, the input of the encoder signal is stopped (S18:
NO), when the non-recording state continues for a predetermined time (for example, 2 to 3 seconds) (S20: YES), the process returns to S10. Further, the recording process for one line is completed (S19: YE
S), when the print instruction switch 13 is turned off (S17: NO), the process proceeds to S20. Further, when the movement of the main body case 10 is temporarily stopped during the recording operation, NO is determined in S18, and the process proceeds to S20.
When the print instruction switch 13 is temporarily turned off, it is determined as NO in S17 and the process proceeds to S20.
If NO is determined in S, the processing after S16 is repeated, and the recording processing is continued.
