Next, the electronic component mounting device moves the minute component placement assembly toward the upper side of the printed wiring board. Then, the minute component arranging component lowers the shaft body, and the electronic component adsorbed on the nozzle is placed (mounted) on the surface of the printed wiring board to raise the shaft body. By repeating this operation, a large number of electronic components are mounted on the surface of the printed wiring board, in order to mount a plurality of electronic components on the surface of the printed wiring board with good efficiency (in a short time), usually, the minute component configuration component is designed to be A structure having a plurality of shaft bodies each having a suction nozzle at the lower end thereof is provided, and the movement of the minute component arrangement assembly at a high speed is repeated. -5-201233269 Patent Document 1 discloses a minute component arrangement assembly (head assembly) having a plurality of (for example, 10) shaft bodies (drive shafts) each having a suction nozzle at its lower end.

S -6- 201233269 Excellent for simple construction and lightweight. If the mass of the small part configuration component is large, since the inertia generated by the high-speed movement of the minute part configuration component is started or stopped, there is a case where the movement accuracy (positioning accuracy) is lowered, and it is required for movement. The power consumption is also large. In the minute component arrangement of Patent Document 1, since each of the shaft bodies has a complicated structure including a lifting/lowering device (a total of one linear motor), it is difficult to reduce the weight. The minute component arrangement unit of Patent Document 2 has a complicated structure in which a plurality of fulcrum bodies are rotated (revolved) by a rotary head, and thus it is difficult to reduce the weight. Further, since each of the shaft systems is moved in the horizontal direction by the rotation (revolution), the position of the electronic component adsorbed to the nozzle of the shaft body fluctuates unless the rotary head is rotated and positioned with high precision. It is also possible to rotate the rotary head with a high-precision rotary drive, but this rotary drive has a complicated structure and has a tendency to increase the mass of the minute component arrangement. An object of the present invention is to provide a minute component arranging assembly which is simple in construction and easy to be lightweight.

(3) Each shaft body is designed to be rotatable within the bearing. [Effect of the Invention] The minute component arranging unit of the present invention has a simple structure and is easy to be lightweight because it is not necessary to provide a lifting/lowering device for each of the shaft bodies. [Embodiment] A minute component arrangement assembly of the present invention will be described with reference to the drawings. Fig. 1 is a front view showing a configuration example of a minute component arrangement unit 1 of the present invention.

S -8- 201233269 Moreover, Fig. 2 is a view of the micro component configuration component 10 of Fig. 1. Further, in the above-mentioned first drawing, the electronic components 91a to 9 If, the brackets 92 of the components, the washers 18 attached to the respective circumferences of the shaft bodies 13a to 13f, and the frame body for supporting and fixing the lifting mechanism 15 are not shown in cross section. . Further, a connector (not shown in Fig. 2: 11) is provided for the paper surface of the frame of the housing 16. The lower part of the minute component arrangement shown in Fig. 1 and Fig. 2 is composed of a plurality of small parts lifting means (example: l5a), which are composed of a shaft body (for example, a shaft body 13a) and a bearing body 14 (example) The lower end of the shaft body 13a) is provided with a pressure reducing device component suction nozzle (for example, the suction nozzle 12a), and the bearing 14 is around the body for guiding the lifting and lowering of the shaft body; The top of the body and the lower end of the nozzle are arranged in a positional relationship of the same height, and the entire row is arranged in the width of the shaft; the frame 16 supports the fixed lifting mechanism 15; the shaft body and the frame 16 of each lifting means of the elastic body Engagement, the height of the shaft body support is all set to a predetermined height; the pressing device 51 is disposed at intervals above the top; the pressing auxiliary member 161 is pressed against the top of any shaft body and the bottom surface of the pressing device 51. And the pressing auxiliary member driving mechanism 171 is connected to the pressing 61, and drives the pressing auxiliary member 61 to perform the horizontal movement of the minute part arranging assembly 10, for example, the supporting plate 1 9 is set in the electronic part. Drive unit provided in the mounting device In the state of the left side, the left side of the housing is surrounded by the ring 16 and the front side of the sub-loader. The first side of the sub-frame is composed of a lifting device. The small structure of the structure is provided in the direction in which the shaft elevating mechanism is located. The spacing of the shafts that can be inserted; the auxiliary members are moved and positioned to be solidified, and are incorporated into the electronic component mounting device -9 - 201233269. By the operation of the driving device, for example, the minute component arranging unit 10 between the carriage 92 in which a plurality of electronic components are housed and the printing unit 11: 93) is moved. In the small part configuration component 1 〇, for example, there are lifting means: a total of six. The number of the lifting means (that is, the number of the shaft body having the small attached mouth) is set to be usually 2 to 30, 3 to 20, and more preferably 4 to 10. Within the scope. The lifting/lowering means 15a is composed of a component suction nozzle 12a, a shaft body 13a, and a bearing 14 connected to a pressure reducing mechanism (not shown). The structure of each of the lifts 15b to 15f is the same as that of the lift means 15a. The following means 15a is a representative example, and the structure of the elevating means 15a to 15f is described. The decompression mechanism is connected to the connector 11 11a provided in the casing 16. As the pressure reducing mechanism, for example, a pump (not shown) which is known as a jet vacuum pump can be used. The pressure reducing mechanism can be connected to the small component suction nozzle, and as shown in the above, it is preferable to connect the small component adsorption nozzle 12a through the internal space 22 which is regarded as the hollow shaft body 13a. According to this connection method, when the electronic component 91a is attached and the shaft body 13a and the minute component suction nozzle 1 are lifted and lowered, the pressure reducing mechanism does not rise with the suction nozzle 12a, thereby achieving a smooth lifting of the shaft body 13a. By depressurizing the inner portion 22 of the shaft body 13a by operating the pump of the pressure reducing mechanism, the electronic component can be attracted to the small component suction nozzle 1 2 such as a repetitive wire plate (speed shift I 5a to 15f is preferable. The micro-drop means is connected to the 2 figure represented by the lifting and moving pipe body in order to suck 2a - take off and land, due to the space under the space a

S -10- 201233269 _. In order to decompress the internal space 22 of the shaft body 13a, a hole 23 connected to the internal space 22 is formed in the shaft body i3a. Further, an annular gasket 18 is attached to each of the upper and lower sides of the hole 23 around the shaft body 13a. By stopping the operation of the pump so that the internal space of the shaft body 13a is equal to the external air pressure (or forming a pressure higher than the external air pressure), the electronic component can be detached from the lower end of the small-part suction nozzle 1 2a. A bearing 14 for guiding the lifting and lowering of the shaft body 13a is provided around the shaft body i3a having the minute component suction nozzle 12a. As the bearing 14, a well-known linear motion bearing (for example, a ballbush) is used. The elevating means 15a to 15f are an elevating mechanism 15 in which the top of each of the shaft bodies and the lower end portion of the nozzle are arranged in the width direction of the shaft body so as to constitute a minute part. The elevating mechanism 15 is supported and fixed to the casing 16 through the bearings 14 of the respective elevating means. The frame 16 is fixed to the support plate 19 through the connecting member 24 and the rotary driving device 83. The minute component arrangement unit 1 includes an elastic body 17 which is engaged with the shaft body of each of the lifting and lowering means and the frame body 16, and supports the shaft body such that the height of the top portion thereof becomes a predetermined height. As the elastomer 17 ', a coil spring is used. For example, a rubber cylinder or the like may be used instead of the coil spring. In addition, the above-mentioned "predetermined height" means that when the shaft body is lowered, the lower end of the micro-component suction nozzle can reach the height of the electronic component (small part), and the appropriate height is set in accordance with the device into which the micro-component arrangement component is incorporated. . For example, when the top surface of the shaft body 13a is pushed down, the elastic body 17 that is engaged with the shaft bodies 13a11, 201233269 and the frame body 16 is shortened. Therefore, when the pressing of the shaft body 13a is stopped, the elastic body 17 is elongated and the shaft body 13a is raised. The above elastic body can also be engaged with the shaft body and the bearing (for example, the bearing 14). The engagement between the above-mentioned elastic body and the shaft body and the frame body (or the bearing) will be described in detail later. In order to raise and lower the plurality of support shafts 13a to 13f, the pressing device 51 is disposed above the top of each of the shaft bodies with an interval therebetween. The pressing device 51 is composed of a movable block 52 that is disposed above the plurality of shaft bodies 13a to 13f so as to be movable up and down and has a bottom surface facing the upper end surface of each of the shaft bodies; the rotation driving device 53' There is a rotating shaft 53a disposed above the movable block 52 and disposed in parallel with respect to the bottom surface of the movable block 52; and a rod 54 having one end connected to the rotary driving device 53 The center of the rotating shaft 53a is a different position, and the other end is connected to the side surface (or the top surface) of the movable block 52, and can be tilted and moved around the respective end portions. The movable block 52 and the plates 55 provided in the rotary drive unit 53 are connected to each other via the linear motion guides (linear guides) 56 and 56. Each of the linear motion guiding devices 56 is constituted by a rail 56a extending in the vertical direction and a slider 56b mounted to slide on the rail 56a. The movable block 52 is designed to be movable (lifted) along the rail 56a together with the slider 56b of each of the linear motion guiding devices 56. When the rotation shaft 53a of the rotation driving device 53 is rotated in the direction (clockwise direction) indicated by the arrow 59a in the first drawing, the lever 54 presses the movable block 52, thereby guiding the movable block 52 and the linear motion. Slip of device 56

S -12- 201233269 The moving piece 56b starts to descend. On the other hand, when the rotation shaft 53a of the rotation driving device 53 is rotated in the opposite direction (counterclockwise direction in Fig. 1), the lever 54 pulls up the movable block 52, thereby guiding the movable block 52 and the linear motion. The slider 56b of the device 56 rises. Since the number of parts of the pressing device 51 is small, it has the advantages of simple structure and easy weight reduction. Further, the rotation driving device 53 and the lever 54' of the pressing device 51 have a function of a linear motion driving device that moves (lifts) the movable block 52 in the vertical direction. The rotary drive unit 53 and the lever 54 can also be replaced by a well-known linear motion drive unit. As an example of the linear motion driving device, a linear motor or a linear motion driving device in which a rotary driving device and a feeding screw are combined may be mentioned. The minute component arrangement unit 10 includes a pressing auxiliary member 61 that can be inserted into the top of any of the shaft bodies 13 a to 13 f and the bottom surface of the pressing device 51 (that is, the bottom surface of the movable block 52). The interval between the pressing member and the pressing assisting member driving mechanism 71 is connected to the pressing assisting member 61, and drives the pressing assisting member 61 to move in the horizontal direction and to be positioned. Figs. 1 and 2 show a state in which the pressing assisting member 61 is inserted into, for example, a space (gap) between the top of the shaft body 13 3 and the bottom surface of the pressing device 51. The plate 62a that supports the pressing assisting member 61 is fixed to the linear motion guiding device 63. The linear motion guiding device 63 is composed of a rail 63a extending in the up-and-down direction and a slider 63b slidably mounted on the rail 63a. The rail 63a is fixed to the plate 62b, and the slider 63b is fixed to the plate 62a. A plate 62c is fixed to the lower end surface of the plate 62a. The plates 62b and 62c are connected to each other through the elastic bodies -13 - 201233269 bodies 64, 64. As the elastic body 64, for example, a coil spring is used. Therefore, by lowering the movable block 52 of the pressing device 51, the pressing assisting member 61 is pressed (pressed) on the movable block 52, and the plates 62a, 62c and the slider 63b are moved downward along the rail 63a ( decline). At this time, the elastic body 64 of the connecting plate 62b and the plate 62c is elongated. Therefore, the elastic member 64 can be shortened by raising the movable block 52, and the pressing assisting member 61 moves upward (rises) along the rail 63a together with the plates 62a and 62c and the slider 63b. With this mechanism, the lifting and lowering of the pressing assisting member 61 can be performed. Further, the plate 62b supporting the linear motion guiding device 63 is fixed to the other linear motion guiding device 65. The linear motion guiding device 65 is composed of a rail 65a extending in the horizontal direction (along the direction of the alignment of the shaft bodies 13a to 13f) and a slider 65b slidably mounted on the rail 65a. The rail 65a is fixed to the end surface of the shelving plate 21 extending from the support plate 19 in the horizontal direction. Therefore, the pressing assisting member 61 can be along the rails 65a along the rails 65a together with the plates 62a, 62c, the linear motion guiding device 63, the plate 62b, and the slider 65b of the linear motion guiding device 65 (along the shaft bodies 13a to 13f) The entire column direction) moves. The pressing auxiliary member driving mechanism 71 is constituted by an endless belt 72 and a driving device 73 that realizes the cyclic movement of the endless belt 72. The driving device 73 is a rotary driving device (for example, a motor) 74 having a rotating shaft 74a, and a pulley 75a to which the rotating shaft 74a is connected, and another

S -14- 201233269 Four pulleys 75b to 75e. The timing belt is used as the endless belt 72, and the timing belt pulley is used as the pulleys 75a to 75c for supporting the inner surface of the endless belt 72. The endless belt 72 is connected to the plate 62b by, for example, an L-shaped connecting member 76 for supporting the pressing assisting member 61. Therefore, by rotating (or reversely rotating) the rotation shaft 74a of the rotation driving device 74 and circulating the endless belt 72, the pressing assisting member 61 connected to the endless belt 72 through the transmission connecting member can be moved in the horizontal direction. And positioning. The pressing auxiliary member driving mechanism 71 using the endless belt has an advantage that the structure is simple and easy to be lightweight. Further, the pressing assisting member driving mechanism 71 has a function as a linear motion driving device that moves the pressing assisting member 61 in the horizontal direction. Instead of the pressing auxiliary member driving mechanism 71, a well-known linear driving device can be used. As an example of the linear motion driving device, a linear motor or a combination of a rotary driving device and a direct acting driving device for feeding the screw can be cited. Next, an example of the operation of the pressing assisting member 61 will be described with reference to Figs. 3 to 5 of the drawings. Figs. 3 to 5 show the pressing device 51, the pressing assisting member 61, and the pressing assisting member driving mechanism 71 of the minute component arrangement unit 1 shown in Figs. 1 and 2 . As shown in Fig. 3, the rotation driving device (Fig. 2: 74) of the pressing assisting member driving mechanism 71 is actuated by the pulley 75a' connected to its rotating shaft, for example, in the direction indicated by the arrow 79a. Rotate to cause the endless belt 72 to circulate in the direction indicated by arrow 79b. Thereby, the pressing assisting member 61 is moved in the direction indicated by the arrow 69a (the right direction in the drawing). -15-201233269 Further, after the pressing assisting member 61 is moved above the top of the arbitrary shaft body, the positioning of the pressing assisting member 61 in the horizontal direction can be performed by stopping the operation of the above-described rotation driving device. Fig. 4 shows a state in which the pressing assisting member 61 is positioned, for example, above the top of the shaft body 13b shown in Fig. 1 by the above-described positioning operation. Further, as shown in Fig. 4, the rotation driving device (Fig. 2: 53) of the pressing device 51 is actuated, and the movable block 52 is lowered by the rotation shaft 53a in the direction indicated by the arrow 59a. The pressing assisting member 61 is pressed by the movable block 52 to move (drop) in the direction indicated by the arrow 6 9b. Fig. 5 shows a state in which the pressing assisting member 61 is lowered. The pressing auxiliary member 61 is positioned above the top of the shaft body 13b shown in Fig. 1 as described above. Therefore, by lowering the pressing assisting member 61 as described above, the shaft body 13b shown in Fig. 1 and the minute component suction nozzle 12b are lowered together. Further, by raising the pressing assisting member 61, the elastic body 17 supporting the shaft body 13b is extended, and the shaft body 13b is again raised. Therefore, in the minute component placement unit 10 shown in FIGS. 1 and 2, the pressing assisting member driving mechanism 71 moves the pressing assisting member 6 1 to the top of the arbitrary shaft body and performs positioning, and then borrows When the pressing assisting member 61 is moved up and down by the pressing device 51, the shaft body can be selectively lifted and lowered together with the minute component suction nozzle provided at the lower end thereof, that is, it is not necessary to provide the lifting and lowering driving device for each of the shaft bodies. Therefore, the structure is simple and easy to be lightweight. Moreover, the plurality of axle shafts 13a to 13f are respectively fixed to the casing 16, and

S -16- 201233269 does not move horizontally in each axis, so it is not necessary to use a drive that allows the shaft to move in the horizontal direction and is positioned with high precision. Next, a method of using the small component arrangement unit 1A, for example, a method of mounting the electronic components 9 1 a to 9 1 f housed in the carriage 92 on the surface of the printed wiring board will be described. First, as shown in Fig. 1, the pressing assisting member 61 is moved in the horizontal direction by pressing the auxiliary member driving mechanism 71, and positioned above the top of the shaft body 13a. Thereby, the pressing assisting member 61 is inserted into the space (gap) between the bottom surface of the pressing device 51 (i.e., the bottom surface of the movable block 52) and the top of the shaft body 13a. Then, by lowering the movable block 52 of the pressing device 51 and the pressing assisting member 61, as shown in Fig. 6, the shaft body 13a and the minute component suction nozzle 12a are lowered together. After the lower end of the minute component suction nozzle 1 2a reaches the electronic component 91a, the electronic component 91a is attracted to the lower end of the adsorption nozzle 12a by actuating the pressure reducing mechanism. Then, the pressing assisting member 61 is raised by raising the movable block 52 of the pressing device 51, and as shown in Fig. 7, the shaft body 13a rises together with the minute component suction nozzle 12a to which the electronic component 91a is attracted. . In this way, the adsorption of the first electronic component 9 1 a is performed. Next, the pressing assisting member 61 is moved in the horizontal direction by pressing the auxiliary member driving mechanism 71, and positioned above the top of the shaft body 13b as shown in Fig. 8. Further, in the same manner as described above, by moving the movable block 52 of the pressing device 51 and the pressing assisting member 61 together, as shown in Fig. 9, the shaft body 1 3 b and the minute part suction nozzle 1 2 b are placed. Decline. The electronic component 91b is attracted to the lower end of the adsorption nozzle 12b by operating the decompression device after reaching the electronic component 9 1 b at the lower end of the micro-part suction nozzle 1 2b at -17-201233269. Then, by pushing the movable block 52 of the pressing device 51, the pressing assisting member 61 is raised, and the shaft body 13b and the minute component suction nozzle 12b sucking the electronic component 91b are lifted up. Then, the adsorption of the second electronic component 91b is performed. By repeating the same operation, the respective electronic parts 91a to 91f are attracted to the minute part adsorption nozzles 12a to 12f as shown in Fig. 1 . Then, after moving the minute component placement unit 10 to the upper side of the printed wiring board 91 as shown in Fig. 1, for example, the shaft body 1 3 f and the minute component suction nozzle 12f are lowered together, whereby the electronic component can be removed. The 91f is configured (mounted) on the surface of the printed wiring board 93. Similarly, the remaining electronic parts are placed on the surface of the printed wiring board 93. As shown in Fig. 2, the pressing assisting member 61 is preferably constituted by a disk-shaped member 61a and a moving member 61b that rotatably holds the disk-shaped member 61a. As the pressing assisting member 61, for example, a roller with a shaft, a member provided with a rotary bearing around the shaft, or a gear follower used for a gear mechanism can be used. When the pressing assisting member 61 is constituted by the disk-shaped member 61a and the moving member 61b, when the pressing assisting member 61 moves in the horizontal direction, the disk-shaped member 61a is in surface contact with the bottom surface of the pressing device 51 (that is, The bottom surface of the movable block 52 is rotated on one side. Thereby, the friction between the pressing assisting member 61 and the pressing device 51 is extremely small, and therefore the durability of the pressing assisting member 61 is good.

In addition, the pressing means may be disposed above the pressing assisting member via a gap so that the pressing assisting member does not come into contact with the pressing means and is moved and positioned in the horizontal direction. In this case, for example, the pressing auxiliary member may be constituted by a metal member. Further, in the minute component arranging unit of the present invention, it is preferable that each of the shaft bodies is rotatable in the bearing so that minute parts (for example, electronic parts) to which the minute part suction nozzles are attached can be arranged in a predetermined direction. Each of the shaft bodies of the minute component arrangement unit 10 shown in Figs. 1 and 2, for example, the shaft body 13a is supported by the bearing 14 in a state where it can be raised and lowered and rotated. In order to rotationally drive the respective shaft bodies, a bearing 81 is provided around each of the shaft bodies. As the bearing 81, a well-known bearing can be used so that the shaft body can be lifted and lowered and supported in a non-rotating state. For example, a plurality of straight grooves may be formed on the outer peripheral surface of each of the shaft bodies at intervals in the circumferential direction, and a spline bearing may be used, and the shaft body may be lifted and lowered in a non-rotation state by being engaged with the straight grooves. Supported under. A rotary bearing 82 is mounted around each of the bearings 81 so that the bearing 81 can rotate together with the shaft. Further, the shaft bodies 13a to 13f are respectively provided with pulleys 84a to 84f through the bearing 81. On the other hand, the minute component arrangement unit 10 includes a rotation driving device 83. The rotation shaft 83a of the rotation driving device 83 is provided with a pulley 85a» The pulley 85a is connected to the pulley 85b through the endless belt 86a. The pulley 8 5b is coupled to the pulley 85c via its rotating shaft 87. The pulleys 85c are respectively connected to the pulleys 84a and 84b via the endless belt 86b, and are connected to the pulleys 84b and 84c via the ring -19 - 201233269 belt 86c. The pulley 85a is similarly connected to the pulley 85d through the endless belt 86d. A pulley (not shown) connected to the pulley 85d via the rotation shaft is connected to the pulleys 84d and 84e' via the endless belt 86e, and is connected to the pulleys 84e and 84f via the endless belt 86f. . Therefore, the rotation driving device 83 is driven to rotate the rotation shaft 83a, whereby the pulleys 84a to 84f are rotated, and the shaft bodies 13a to 13f can be simultaneously rotated while being supported by the bearing 81. Two rotary driving devices are provided instead of the rotary driving device 83, and the pulleys 84a, 84c, and 84e are connected to the rotating shaft of one of the rotary driving devices through the pulley and the belt member, and the pulley is passed through the pulley and the belt. 84b, 84d, 84f are connected to the rotation shaft of the other rotary drive device. That is, the shaft bodies 13a, 13c, and 13e are simultaneously rotated by one of the rotary driving devices, and the shaft bodies 13b, 13d, and 13f are simultaneously rotated by the other rotation driving means. In the first embodiment, the small component suction nozzle 12f provided in the shaft body 13f is used to attach the electronic component 91f to the surface of the printed wiring board 93, and the shaft body 1 3e and the minute component are used. The nozzle 1 2e is rotated to rotate the electronic component 91e adsorbed by the nozzle 12e in a predetermined direction. Therefore, a plurality of electronic parts can be mounted on the surface of the printed wiring board with good efficiency (in a short time). Since the rotation driving method of the shaft body is well known, no explanation is given. Further, in the case where the respective shaft bodies are rotationally driven, the engagement of the elastic body, the shaft body, and the frame body (or the bearing) that supports the respective shaft bodies must be performed.

S -20- 201233269 This is caused by the rotation of the shaft. For example, as shown in Fig. 2, the elastic body 17 is engaged with the shaft body 13a by the cylindrical body 25a' supported by the upper end portion thereof and transmitted through the cylindrical body 25a and the rotary bearing 26. The elastic body 17 is further supported by the lower end portion of the other tubular body 25b, and is engaged with the casing 16 through the tubular body 25b. Therefore, the shaft body 13a is rotatable in a state of being supported by the rotary bearing 26, and by pushing the top thereof downward, the rotary bearing 26 and the cylindrical body 25a can be lowered together. Further, by supporting the lower end portion of the elastic body 17 directly or through another member, it can be engaged with the bearing (for example, the bearing 14). Further, when the respective shaft bodies are not rotationally driven, the upper end portion of the elastic body 17 is fixed to the top of the shaft body without being transmitted through the rotary bearing, and is engaged with the shaft body. Fig. 1 is a view showing the minute component arrangement unit 1 of the second drawing, in order to simultaneously adsorb all the electronic parts 91a to 91f, the shaft body 13 3 to 13 and the minute part adsorption nozzle 12 12 The state of the descending state is as shown in Fig. 12, and it is preferable that the pressing assisting member 61 can be moved to the outer side of the lower surface of the pressing device 51 (i.e., the bottom surface of the movable block 52). According to this configuration, the pressing assisting member 61 is moved to the outer side of the lower region of the bottom surface of the pressing device 51 by pressing the auxiliary member driving mechanism 71, and then by moving the movable block 52 of the pressing device 51 downward, As shown in Fig. 12, 'the shaft body is simultaneously lowered, and the electronic parts 9 1 a to 9 1 f are simultaneously adsorbed on the plurality of minute parts adsorption nozzles - 21 - 201233269 12 a to 12f, respectively. With this operation, since the electronic component can be attracted to the small component suction nozzle 1 2 1 2 f in a short time, a plurality of electronic components can be mounted on the surface of the printed wiring board with excellent efficiency. The minute component arrangement of the present invention can be incorporated into a device for mounting or moving various minute parts typified by minute electronic parts and mechanical parts. As an example of the electronic component, a wafer type electronic component typified by a wafer capacitor and a chip resistor can be cited. As an example of the mechanical component, a small-sized optical lens and an optical filter used in a camera mounted on a mobile phone can be cited. The component arranging component of the present invention can be used, for example, in a device in which a small-sized optical lens and an optical filter as described above are mounted at a predetermined position inside a mobile phone, or a small storage body.
