Abstract: A tape feeder feeds electronic components by advancing a tape intermittently. The tape feeder comprises a motor controller for controlling a motor, which rotatively drives a sprocket to advance the tape, and a communication unit for receiving a control signal from a control unit of an electronic component mounting apparatus and transmitting a control parameter such as a rotating speed, an amount of rotation, and acceleration and deceleration pattern to the motor controller. The tape feeder has such a structure that a tape advancing speed and an amount of tape advancement are easily changeable according to a type of the electronic components by changing the control parameter of the rotating speed and the amount of rotation of the motor.

Abstract: An apparatus and method for mounting electronic parts wherein a transfer width between a pair of transfer rails is changeable according to a size of a substrate. A mounting head picks up electronic parts at a parts supply member and keeps its stand-by position for mounting the electronic parts on the substrate. The stand-by position of the mounting head is determined according to the changed amount of the transfer width.

Abstract: In an image taking apparatus having a mechanism for freely inserting/removing an IR cut filter on an optical axis of an image taking optical system of the image taking apparatus, the IR cut filter is made of one of film material and sheet material. Further the mechanism changes an image taking mode of the image taking apparatus between a first mode where the IR cut filter is located on the optical axis of the image taking optical system and a second mode, that is a low level light image taking mode where the IR cut filter is removed from the optical axis of the image taking optical system.

Abstract: A mounting head unit for an electronic component for making a pick-up operation of the electronic component and loading operation thereof is removably attached to a head mounting bracket of an electronic component mounting device. Each mounting head unit is provided with a control board for controlling the a mounting mechanism including a plurality of unit mounting heads each equipped with an adsorption nozzle for holding the electronic component. In the mounting operation, on the basis of the operation command from a main unit control section for controlling the entire operation of the electronic component mounting device, the control board controls the operation of each of the unit mounting heads. In this way, the replacement of wirings in replacing the mounting head can be easily made and the time delay in signal processing can be removed to realize the high speed operation.
