The Y-axis drive unit 64' moves the two f 62 and the laser displacement sensor 63 in the Y-axis direction. Such an arrangement can provide a minimum inter-sleeve gap between the nozzles 62 on the plurality of head units 60, and effectively form various patterns with small intervals therebetween on the substrate 20 without being limited to a specific one. Pattern shape, and the travel of the early element (6) <Second Embodiment> I will take the McCaw diagram 5 and Fig. 6, illustrating that the dispenser according to the second embodiment of the present invention is common in the first and second embodiments The components will be denoted by the same reference symbols, and a detailed description of these components will be omitted herein. Fig. 6 is a perspective view showing a dispenser according to a second embodiment of the present invention. Fig. 6 is a front view showing the dispenser of Fig. 5. 2 and FIG. 6, the X-axis driving unit 70 of the head unit 60 in the X-axis direction according to the second embodiment of the present invention includes the head support member 50 and extends in the direction. The fixing portion 71, with the support plate 69 of each of the head sheets S 60 and inserted into the fixing portion u* and the portion 72, the shaft driving unit 70 interacts with the moving portion η = ^ by the fixing portion 71 to guide the head units (9) Moving along the guide 51, the movement is longer than the x-axis direction, wherein the guide 51 is mounted to the head support member 5: the 'fixing portion 71' includes a plurality of fixing portions. The fixing portions 71 are arranged to be spaced apart from each other. According to the second embodiment of the present invention, the two heads = 6 〇 71, i.e., the U 711 and the second fixing portion 712, are provided at the upper portion and the lower portion of the phase = 60 so as to be apart from each other by a predetermined interval. Further, the vehicle rest portion 72 is disposed such that one moving portion 72 is different from the other moving portion. That is, if the moving portion 72 of the head unit 6G is attached to the fixed portion 7A, the moving portion W attached to the adjacent head unit 6A is coupled to the second fixed portion 712. The movement in the a direction is the effect of the width, whereby the head unit 6 〇 = page is as early as the moving portion, and the head unit 6G is close to each other. Again, separated by Dh. The fruit, the sinful handle, can reduce the small interval between the head units (9). Therefore, the most suitable part of the nozzles 62 for the fresh (10) is designed to be suitable for the weight of the head unit (9). The motion is wider than the corresponding head unit 6〇. In the & example, the plurality of head units (9) may not be close to each other to the minimum interval due to the movement unit W. However, the rooting portion 72 is located at a different position of 4, so that the above problem can be overcome as such - "the shaft is built according to the fourth embodiment of the present invention, and the moving portion 72 of the head sheet 7t 60 is provided to the other head. The moving portion 72' of the unit 6'' is not aligned with each other in the z-axis. Therefore, the minimum χ-axis spacing between the nozzles 62 on the plurality of head units 60 is sturdy and allows for a small interval between the patterns on the substrate 20 to be efficiently formed. The various patterns 'are not limited to a particular pattern shape and reduce the stroke of 60. The thousand dispensing machine according to the present invention is constructed as described above, and the transmitting portion 63 and the receiving portion 632 of the laser displacement sensor 63 are arranged in a row in the γ-axis direction, and the driving portion 64 is applied to the γ-axis. The driving unit 64 moves the nozzle q and the life-displacement displacement sensor 63 in the Y-axis direction, thereby reducing the head units 6〇1 to 1360442 20, and the heads of the heads can be replaced by G. _ case to the substrate. . Furthermore, the dispenser construction according to the present invention: = the moving portion 72 and the spray head provided on the adjacent head unit: = 3, and the small X-axis interval Dn between the units 6 . Efficiently forming various patterns having a small interval Dp between the patterns can be specific to the substrate, and the head unit 6G can be lowered. In addition, as described above, the present invention provides a width of the dispensing one, and thus reduces the spacing between the nozzles, thereby allowing various patterns to be formed at the base and lowering the head units. The behavior of the line. Further, the present invention provides a dispensing machine in which the adapter unit moves the head earlier than the moving portion in the X-axis direction, and the other moving portion adjacent to the previous moving portion is different in the position of the ζ_ Therefore, the minimum X-axis spacing. The foregoing embodiments of the present invention can be implemented independently, and these embodiments can also be implemented in combination. Although the preferred embodiment of the present invention has been disclosed for the purpose of illustration, it is understood that various modifications, additions, and modifications may be made without departing from the spirit and scope of the invention as disclosed in the appended claims.
