- These print heads 74 K, 74 C, 74 M, 74 Y and the inks 86 K, 86 C, 86 M, and 86 Y are connected by ink supply tubes 90, respectively, and the ink tanks 86 K, 86 C, 8 6 M, 86 Y ink is supplied to the print heads 74 K, 74 C, 74 M, and 74 Y.
- An ink supply needle 92 is fixed to the tip of the ink supply tube 90, and is attached to a sponge built in the print heads 74K, 74C, 74M, and 74Y. Supply needle 92 is piercing.
- the projecting part protrudes to the left or right depending on the position of the moving part 80 and the main body part 70, so that the ink tank is moved in the scanning direction by the projecting size. It can be large and can store a lot of ink. As a result, more ink can be supplied to the print head without increasing the outer dimensions of the plotter.
- the carriage 100 has a main body 110 that scans in the scanning direction (arrows E and F) and a moving part 120 that is fixed to the main body 110 so as to be movable in the scanning direction. have.
- a guide groove 112 extending in the scanning direction is formed in the main body 110, while a guide rail 122 is formed in the moving part 120 to fit into the guide groove 112. Have been. For this reason, the moving section 120 can move freely on the main body 110 in the scanning direction.
- the main body 110 is equipped with a print head 1] 4K, 114C,] 14M, 114Y.
- a relay board 130 for supplying communication and power is mounted on the moving section 120.
- a cable 39 is connected to the relay board 130.
- each mark on the relay board 130 Short head connected to character heads 1 14 K, 1 1 4 C, 1 1 4 ,, 1 1 4 1 1 3 2 ⁇ , 1 3 2 C, 1 3 2 M,] 3 2 One end of ⁇ is connected.
- a curved portion bent in a “U” shape] 34 is formed at the center of each short flexure 13 32 K, 13 2 C, 13 22,,] 32 ⁇ . It is configured such that the stress when the moving part 120 moves does not fall on each short circuit.
- a connector 1336 of a cable 39 for connecting the relay board 130 to an engine controller (not shown) is also attached to the middle board 130.
- the moving part 120 When the carriage 100 moves to the left end in the scanning direction, as shown in FIG. 7, the moving part 120 is pushed in the direction of arrow F by the main body side wall 1a (see FIG. 4), and the moving part is moved. The right side of 120 protrudes to the right of main body 110. However, when the carriage 100 has moved to the right end in the scanning direction, the moving section 120 is moved in the direction of arrow E by a main body side wall (not shown) located on the right side of the main body corresponding to the main body side wall 1a. When pressed, the left part of the moving part 120 protrudes to the left from the main body 110. As described above, the moving section 120 projects leftward or rightward depending on the position of the main body 110.
- the relay board 130 can be lengthened in the scanning direction by the protruding size. As a result, the length of the relay board 130 can be shortened in the direction (width direction) orthogonal to the scanning direction, and the entire device can be downsized accordingly.
- the moving section 120 was moved by abutting the side wall of the main body.However, the length of the cable 39 connected to the connector 1 36 of the moving section 120 was shortened, and the main body was moved. Eliminating the margin when the 110 moves to the end in the scanning direction, the moving area of the moving section 120 is restricted by this cable 39, and the moving section 120 is moving toward the end. It may be configured to be moved from the main body 11 ⁇ . Industrial applicability
