Control setup 90 mainly has: EEPROM 94, it stores the list and the erection schedule data that become the electronic unit of mounting object, defines the lift-launch order of electronic unit, the loading position of each electronic unit on substrate K, represents the receiving position etc. that each electronic unit from which electronic component feeder 21 is received in these erection schedule data; ROM 92, it stores installation action control program and substrate transmits control program; CPU 91, it performs various program; And RAM 93, it becomes data storage areas in the execution of various program.
The action of the electronic component mounting apparatus 10 that CPU 91 utilizes aforesaid substrate conveying program and installation action control program to perform is described.
First, if move into the front portion that sensor 314 detects substrate K, then CPU 91 starts the driving of carrying electrical motor 323, moves into substrate K from moving into mouth 312 to moving into buffer area 32.
Then, if the front portion of substrate K is waited for that sensor 315 detects, when then there is the substrate K first moved in central buffer region 33, the conveying of the substrate K moving into buffer area 32 is stopped, when there is not the substrate K first moved into, the driving of conveying electrical motor 333 is also started, from moving into buffer area 32 to central buffer region 33 conveying substrate K.
Thus, substrate K moves from a pair load-transfer device 321 to a pair load-transfer device 331, carries to downstream with the state of the upper surface being placed in this load-transfer device 331.

In addition, when being determined in erection schedule data, making the multiple absorption suction nozzles 41 of boarded head 40 simultaneously or after the absorption action carrying out electronic unit successively, carry out the installation action to substrate K.
Then, if the installation action of electronic unit completes, then drive elevating motor 352, support table 351 is declined.Thus, each conveying 334 drops to the lower limit of movable area, returns each backing roll 336 and protrudes and the state of support belt 331 from below from recess 334b.
Further, status releasing prevented by the substrate of hill holder 319, if confirm that the substrate K first moved into discharges from taking out of buffer area 34, then drives conveying electrical motor 333, from buffer area, center 33 to taking out of buffer area 34 conveying substrate K.
Then, if the detecting by being taken out of sensor 317 by center of the rearward end of substrate K, then CPU 91 makes the driving of conveying electrical motor 333 stop, and, be identified as and can carry next substrate K in central buffer region 33.
Further, when taking out of being delivered to the substrate K taking out of buffer area 34 outside equipment, directly take out of by taking out of buffer area 34.
Then, if the detecting by being taken out of sensor 318 of the rearward end of substrate K, then CPU 91 makes the driving of conveying electrical motor 343 stop, and, be identified as and can carry next substrate K to taking out of in buffer area 34.
