An apparatus for mounting electronic parts and a method of mounting electronic parts capable of effectively performing image capturing at the time of position recognition of the electronic parts. In the apparatus, when images of electronic parts are taken for position recognition of the parts in the mounting of a plurality of the electronic parts held by a mounting head on a circuit board, it is adapted such that pixel signals are output only from specific necessary pixels. More specifically, pixel selecting information for allowing image signals to be selectively output from a plurality of specific pixels of a photodetecting section () of a CMOS area sensor is generated based on mounting schedule data (C) related to a mounting sequence of the electronic parts and part data of the electronic parts stored in data storage (). A pixel selector () is operated in accordance with the pixel selecting information, and thus the image signals are output from the selected specific pixels.

Apparatus for mounting electronic parts

When an image object is read using a camera including a line sensor having pixels arrayed in a line, a relative-movement-detecting section detects a movement of a transfer head holding the object in X direction relative to the camera. The detecting section outputs a movement-detecting signal to a camera-controller every time the object moves a given distance corresponding to a scanning space in X direction. The camera-controller controls a pixel-selecting circuit according to the movement-detecting signal and outputs an image signal from pixels selected based on pixel-selecting information. As a result, even if a moving mechanism of the transfer head has an error, a resolution becomes stable and an exact image is obtainable.

Image reading device and method for the same

An image reading device reads an image of an electronic part as an image pickup object with camera having a line sensor. The line sensor comprises a plurality of pixels having a photoelectric transfer element arranged in series. The image reading device selects pixels periodically one by one and outputs image signals. The pixels for outputting image signals are set based on width data of an image pickup area stored on image pickup area storage . The image reading device monitors a relative positional relation between the image pickup object and the line sensor using a pulse of encoder A, and controls writing of the image signal into an image storage with a storage controller based on length data of the image pickup area. This process can remove uselessness of outputting the image signal from an unnecessary range and storing it, and improve efficient image reading.
