Abstract

Information producing apparatus for producing position and direction information of chip-like electric parts for use in the chip mount system. This apparatus comprises: a tablet digitizer; X and Y axis position memories to store the X and Y axis position data of the cursor; a menu position memory to store the position of the menu drawing which is divided into many menu spots and is attached on the tablet; a menu spot memory in which data corresponding to the menu spots is stored; a discrimination unit to discriminate whether the cursor is located within the menu drawing or not; and an arithmetic operation unit to calculate the menu spot position corresponding to the cursor position when the cursor exists in the menu drawing. When the cursor is out of the menu drawing, the readout data from the X and Y axis position memories is used as the position information on the printed wiring board of the chip-like electric parts to be installed. When the cursor is in the menu drawing, the readout data from the menu spot memory is used as the attaching direction information in accordance with the menu spot based on the cursor position.
