## Abstract

In a mounting system including a loading station having a transport conveyer for conveying printed circuit boards, a mounting machine for fabricating circuit devices by attaching electronic assemblies on printed circuit boards supplied thereto from said loading station, and an unloading station having a transport conveyor for conveying circuit devices supplied thereto from the mounting machine, the loading station includes a discriminating device for discriminating the kind or type of printed circuit boards and for generating a discrimination signal for instructing the kind or type of the printed circuit board. A mounting process in the mounting machine is selectively set by the discrimination signal from the discriminating device. According to this mounting system, even when many kinds of circuit devices are fabricated by many kinds of printed circuit boards, mounting processes can be successively carried out by one mounting line.

## Claims

### Claim 1

A mounting system including a loading station having a transport conveyor for successively conveying printed circuit boards of differing kinds or types, a mounting machine providing a mounting process for mounting electronic assemblies on said printed circuit boards supplied thereto from said loading station, and an unloading station having a transport conveyor for ejecting said printed circuit boards supplied thereto from said mounting machine, wherein said loading station includes a discriminating device for discriminating the kinds or types of said successively conveyed printed circuit boards based upon a magnetic mark applied to the respective printed board and issues a discriminating signal prior to the mounting process to selectively set a type of mounting process for electronic assemblies to be mounted on a respective printed circuit board by the mounting machine during the mounting process.

### Claim 2 (depends on 1)

The mounting system as claimed as in claim 1, wherein said discriminating device discriminates said printed circuit boards by detecting a discrimination mark attached to said printed circuit board.

### Claim 3 (depends on 1)

The mounting system as claimed in claim 1 wherein said mounting process is controlled by a computer, a predetermined software is selected by said discrimination signal from said discriminating device, and said mounting machine is energized by said selected software.

### Claim 4 (depends on 1)

The mounting machine as claimed in claim 1 wherein said mounting process include a positioning process for positioning a printed circuit board, a process for attaching electronic assemblies on said printed circuit board, and a process for inspecting electronic assemblies.

### Claim 5

A mounting system including a loading station having a transport conveyor for successively conveying printed circuit boards of different kinds or types, a mounting machine providing a mounting process for mounting electronic assemblies on said printed circuit boards supplied thereto from said loading station, and an unloading station having a transport conveyor for ejecting said printed circuit boards supplied thereto from said mounting machine, wherein said l discriminating device for discriminating the kinds or types of said successively conveyed printed circuit boards by means of an image processing system which detects an exterior characteristic of the respective printed circuit board and issues a discriminating signal prior to the mounting process to selectively set the mounting processes to be successively executed for mounting a variety of electronic assemblies on a respective printed circuit board by the mounting machine during the mounting process.
