摘要： PROBLEM TO BE SOLVED: To reduce the weight of a table and to speed up the movement of the table by arranging a driving source which constitutes a part of a transfer device outside of the table. SOLUTION: An intermediate loader is arranged between a stocker B which stores a printed circuit board and a table 2 of a printed circuit board perforator. A driving source 13A of a transfer mechanism Co which transfers the printed circuit board at a direction shown by an arrow Y on the table 2, is arranged in the intermediate loader E side other than the table 2, and the driving force from the driving source 13A is transmitted to the transfer mechanism Co by a clutch mechanism H. As there is no driving source 13A there, the weight of the table 2 is reduced so that quicker movement can be made.

摘要： PURPOSE:To arrange a tool exchange device in front of a table or reduce the installation area. CONSTITUTION:A conveyor C conveying a printed board between a stocker B and a delivery device D is supported by a table 2 in front of the table 2. The conveyor C is supported on the table 2 swayably around the axis parallel with the conveyance path, and the conveyor C is preferably formed retreatably to a position lower than the table plane. A tool exchange device E including a drill is preferably supported on the table 2 on this side of the conveyor C. The conveyor C is supported on the table 2, thus the tool exchange device E can be arranged in front of it. The conveyance path of the stocker B can be arranged nearer to the center than the front edge position of a bed 1, the protruded portion of the stocker B from the front face of a driller main body can be reduced, and the whole installation area can be reduced.

摘要： PURPOSE:To reduce time for replacing a tool by pushing up all post group for tool set by pressure of a spindle with such an energizing force that each post for tool set is individually moved back and by delivering the tool to the spindle. CONSTITUTION:A spindle 5 is moved to be positioned above a post 3 for tool set for returning or mounting a tool 2 among a post group 1 for tool set held by a post holding body 4. Then, air is supplied to a post engagement hole 11 from an air hole 16 so as to push up all the posts 3 for tool set at the same time in the direction of the spindle 5. After that, the spindle 5 is lowered and the tool 2 is delivered to the predetermined post 3 for tool set. At this time, the spindle 5 is brought into contact with the upper end of the tool 2 held by the post 3 for tool set in the neighborhood and presses it. And each tool set 3 is lowered by pressure of the spindle 5 against air pressure. Accordingly, delivery of the tool 2 is carried out without any problem.

摘要： PURPOSE:To further shorten the tool change time and simplify structure so as to attain cost reduction. CONSTITUTION:The whole tool setting post group 1 is pushed up toward a spindle 5 with energizing force of such degree that each tool setting post 3 retreats individually by the pressure of the spindle 5. Tools can be thus delivered to the spindle 5. Accordingly, when the spindle 5 is lowered for the return of a tool and the delivery of a new tool, the tool setting post 3 interfering with the spindle 5 is pushed by the spindle 5 so as to retreat or descend. The delivery of the tool to the spindle 5 can be thereby performed without hindrance.

摘要： PURPOSE:To receive and give a tool directly between a spindle and a tool holding device by pressing down a required tool holding member up to a position where the spindle comes into no interference with the tool of another tool holding member to receive and give the tool. CONSTITUTION:When a spindle 11 holding a tool 14 which has completed required machining moves to a position where the tool 14 and a tool post 23 face each other by relative movement to a table 3 and a slider 6 and is positioned, the fluid passage 36 of a cylinder 33 is made to communicate with the atmosphere and a piston 37 is raised, so that the tool post 23 is pressed down, and the ring 15 of the tool 14 held on the spindle 11 is supported to open the chuck 13 of the spindle 11 and release the tool 14, giving the tool 14 to the tool post 23. Then the spindle 11 rises, and at the same time, compressed air is supplied to the fluid passages 34, 36, the piston 37 of the cylinder 33 is pressed down to a standby position to move a table 3 and the slider 6 and move a spindle 111 above the tool 14 to be used next.
