Abstract: Apparatus and method for mounting electronic components enhanced in mounting efficiency by eliminating loss time are disclosed. In the apparatus and method, electronic components are picked up from a supplying unit of the electronic components by a transfer head, and are mounted on a board. The height of components already mounted on the board being conveyed is measured by a height measuring unit comprising a CCD light sensor including a light emitting unit and a light receiving unit. In mounting operation, the transfer height of the transfer head when moving on the board is set to a height enough to keep an allowance to the already mounted components on the basis of the height measurement of components. As a result, without useless elevating motions of the transfer head, the loss time is eliminated and the mounting efficiency is enhanced.

Abstract: A data processing section controls a line connecting section, data transferring section, speech output section and console control section to process and input/output data for responding/reporting. The data processing section analyzes data received from the data base of a supervision and control system which is a connection object via the data transferring section, and effects a process according to the result of analysis, linkage information and message content set from the console via the console control section. The data processing section creates message data of a response message indicating the operating condition of the supervision and control system and supplies the same to the speech output section and supplies a speech message created in the speech output section to a public communication line via the line connecting section.

Abstract: An electronic component is inspected before it is mounted onto a substrate. The electronic component has a plurality of lead rows, each lead row including plural leads arrayed in a line along and protruding from a side face of a main body of the electronic component. Positional data of the plural leads, including altitudinal values representing heights of respective leads, are measured. A plurality of approximate lines are obtained on the basis of the positional data, each approximate line approximating each lead row on a side face of the electronic component main body. Any faulty lead, extraordinarily deformed compared with other leads, is detected on the basis of the positional data. A mutual positional relationship is obtained between the approximate lines, and it is judged whether the mutual positional relationship is within a predetermined range.
