Next, a method of changing the liquid crystal of the A type to the liquid crystal of the B type, and applying the B type liquid crystal to the unit panel region through the nozzle by the coating head unit will be described. First, the liquid crystal remaining in the fourth hole l81e, the tube member 154, the liquid crystal inflow passage 141c, the liquid crystal suction space S, the liquid crystal outflow passage 141d, the tube member 163, and the nozzle 162 is removed. Thereafter, in a state where the first connecting hole 182a is in communication with the first hole 18lb, the driving unit 183 rotates the second block 182 by 9 turns in the counterclockwise direction. The third connection hole 182c is communicated with the third hole 181d as shown in FIG. When the third connecting hole 182c communicates with the third hole 181d, the third hole i8id communicates with the fourth hole i8ie through the third connecting hole 182c and the second connecting recess 18仏. 16 201130571 As shown in Fig. 3, the pick-up motor 132 rotates the piston 142 around the z-sleeve in a counterclockwise direction so that the cut-away portion 142a faces the liquid crystal inflow passage i41c. The motor 121 moves the piston bore 42 upwardly from the bottom of the barrel along the Z-axis to a position z〇. As shown in FIG. 3, FIG. 5, FIG. 6, and FIG. 9, the pipe member 153, the third hole 181d, the third connecting hole 182c, the second connecting recess i82e, the fourth hole 181e, the tube member 154, and the liquid crystal inflow passage are then passed through. I4ic discharges the cleaning liquid stored in the cleaning liquid bottle 157 into the liquid crystal suction space S. Thereafter, as shown in Fig. 4, the motor 132 rotates the piston 142' in the clockwise direction about the z-axis such that the cutout portion 142a faces the liquid crystal outflow passage 丨41 (|. The motor 121 moves the piston 142 downward from the position Z0 to Z1. Thereafter, The cleaning liquid discharged into the liquid crystal suction space S is discharged into the cleaning liquid receiving container (not shown) through the liquid crystal outflow channel i41d, the tube member 163, and the nozzle 162, and thus remains in the fourth hole 181e, the tube member 154, and the liquid crystal inflow passage 141c. The liquid crystal suction space S, the liquid crystal outflow channel 141d, the tube member 163, and the liquid crystal in the nozzle 162 are removed. Then, in a state where the third connection hole 182c communicates with the third hole 181d, the drive unit 183 will block the second block. The second connecting hole 182b is in the clockwise direction, and the second connecting hole 182b is in communication with the second hole I8ic, as shown in FIG. 1A. The second connecting hole 182b and the second hole 181 (the second hole passes through the first connecting hole when communicating with each other) 182b is in communication with the fourth hole I81e. In this state, as shown in Fig. 3, the motor 132 rotates the piston 142 in a counterclockwise Z axis, so that the cutout portion 142a faces the liquid crystal flow = 14k. The motor (2) follows the Z axis from the cylinder. Move the bottom of the piece (4) upwards to live ^ 201130571 in place Next, as shown in FIG. 3, FIG. 5, FIG. 6, and FIG. 1A, the pipe member 152, the first hole 181c, the first connecting hole 182b, the fourth hole 181e, the pipe member 154, and the liquid crystal inflow passage 141c are provided. 'B liquid crystals stored in the second liquid crystal bottle 156 are discharged into the liquid crystal suction space 8. As shown in Fig. 4, the motor 132 then rotates the piston 142' around the z-axis in a clockwise direction so that the cut-away portion 142a faces the liquid crystal The outflow channel Mld. The motor 121 moves the piston m2 downward from the position Z0 to Z1 along the Z axis. Thereafter, the B kinds of liquid crystal discharged into the liquid crystal suction space S are discharged through the liquid crystal outflow channel 141d, the tube member 163, and the nozzle 162 to be cleaned. The liquid receiving container (not shown) 'removes the cleaning liquid remaining in the fourth hole 181e, the tube member 154, the liquid crystal flow path 141c, the liquid crystal suction space S, the liquid crystal outflow channel i41d, the tube member 163, and the nozzle 162. As shown in Fig. 3, the motor 132 rotates the piston 142 about the two axes in the counterclockwise direction, so that the cutout portion 142a faces the liquid crystal inflow passage 141c. The motor 121 moves the piston 142 upward from the bottom of the cylinder member 141 along the Z axis to the position Z0. As shown in Figure 3, Figure 5, Figure 6, and As shown in FIG. 1 , the B type liquid crystal cells stored in the second liquid crystal bottle 156 are then passed through the tube member 152, the second hole 181c, the second connection hole 182b, and the fourth hole by ", the tube member 154, and the liquid crystal inflow channel Hlc." The liquid crystal suction space s. Then, as shown in Fig. 4, the motor 132 rotates the piston 142 about the two axes in the clockwise direction, so that the cutout portion 142a faces the liquid crystal outflow channel i4id. The motor 201130571 m moves the piston i42 downward from the position zo to Z1 along the z-axis. Thereafter, the liquid crystal suction space s # B liquid crystal is transmitted through the liquid crystal outflow channel 14M, the tube member 163, and the nozzle 162 to the unit panel region (not shown). ▲At the same time, the liquid crystal supply unit may further include a third liquid crystal bottle containing a cholesteric liquid crystal (hereinafter referred to as "C type liquid crystal"). In this case, the fifth hole of the second liquid crystal bottle is connected to the first block body 181 by the tube member. Furthermore, the second block 182 also has a fourth connecting hole and a third connecting recess, wherein the third connecting recess communicates with the fourth connecting hole. The fourth connecting hole traverses the central axis of the second block. g is viewed from the side view of the first block 182, and the fourth connecting hole forms an angle of 45 with the third connecting hole. The fifth hole is connected to the third liquid crystal bottle by a pipe. As shown in FIG. 9 'when the third connection hole 182c is in communication with the third hole 181d, when the driving unit 183 rotates the second block 182 by 45° in the counterclockwise direction, the fourth connection hole and the fifth hole are made. The same. When the fourth connecting hole communicates with the fifth hole, the fifth hole communicates with the fourth hole 181e through the fourth connecting hole and the third connecting recess. Thereafter, when the motor 132 moves the piston 142 in the Z-axis direction, the through-tube member, the fifth hole, the fourth connecting hole, the third connecting recess, the fourth hole 181e, the tube member 154, and the liquid crystal inflow passage 141c are stored in the third The C kinds of liquid crystals in the liquid crystal bottle are discharged into the liquid crystal suction space S. Therefore, a single cylinder assembly can also apply C liquid crystal to the unit panel area through the nozzle. Meanwhile, as shown in FIG. 11, FIG. 12, FIG. 13, and FIG. 14, in the second embodiment of the selector 280 of the present invention, the selector 280 can be configured such that each of the connection holes is directly connected to the fourth hole 281e. However, the first embodiment of the present invention is different from the first embodiment in that all the connection holes communicate with the fourth hole 28ie without using the connection recess. - Therefore, in the second embodiment, the second connection hole 282b has the structure of the first embodiment. The first through hole 282a and the third connecting hole 282c are inclined toward the central axis of the second block 282 instead of the vertical central axis. Since the structure "the first connection hole 282a or the third connection hole 282e" can respectively make the first hole lion or the third hole 281d and the fourth hole 2816 (4) without using the i car.
