Abstract: A cartridge for supplying a carrier tape which carries a plurality of electronic components, the tape having a plurality of pockets for accommodating the respective components, and a pair of side portions on both sides of the pockets, the pockets projecting downward from the side portions, the cartridge including a cartridge frame, a tape feeding device mounted on the cartridge frame, for feeding the carrier tape in a feeding direction, a pair of rails provided on the cartridge frame such that the rails extend parallel to the feeding direction, the pair of rails supporting the pair of the portions of the carrier tape, respectively, and permitting movement of the pockets of the tape when the tape is fed on the rails by the tape feeding device, a tape positioning device which positions the carrier tape with respect to a lateral direction in which the pair of side portions of the tape are spaced from each other, and a rail adjusting device which adjusts a spacing between the pair of rails to each of a plurality

Abstract: An electronic-component mounting apparatus including two or more actuators including two or more electric actuators which are provided on a movable member supported by a frame member and supporting an electronic-component mounting head are operable on electric energy, a power source which is provided on the frame member and provides the electric energy, a main control device which is provided on the frame member, an actuator control device which is provided on the movable member and controls the electric actuators, an electricity supplying device which includes a first supplying section provided on the frame member and a second supplying section provided on the movable member and which supplies the electric energy from the power source to the actuator control device, without having any wire connection between the first and second supplying sections, and an information transmitting device which includes a first transmitting section provided on the frame member and a second transmitting section provided on the

Abstract: An apparatus for mounting different sorts of electronic components on a substrate, including a table rotatable about an axis; a plurality of groups of mounting heads supported by the table, each one of the head groups consisting of a plurality of identical mounting heads that differ from the identical mounting heads of each of the other head group or groups, the mounting heads of the each one head group taking an electronic component of a corresponding one of the different sorts from an electronic component supply device and mount the electronic component on a substrate.

Abstract: A component supply device for supplying a component mounting device with electronic components at a supply position, which includes at least three supply tables each having a plurality of supply units mounted thereon such that the supply units have respective supply portions which are spaced from each other along a predetermined line, the supply units holding respective groups of electronic components of respective different kinds, a guiding device for guiding the supply tables such that the supply tables are movable in a moving direction parallel to the predetermined line, and a table positioning device for positioning the supply tables in the moving direction so that the supply portions of the supply units are selectively brought to the supply position.

Abstract: A detecting device for detecting a position of an electronic component in which the component is held by a holder is disclosed. The detecting device includes a first light emitter for emitting a first radiation toward a vicinity of the electronic component, a second light emitter disposed in the vicinity of the holder, for absorbing the first radiation, and emitting a second radiation having a wavelength different from that of the first radiation, toward the electronic component, and a photoelectric device disposed on one of opposite sides of the electronic component which is remote from the second light emitter. The photoelectric means is insensitive to the first radiation and receives a projection image of the electronic component formed by the second radiation.

Abstract: Are disclosed a method of detecting a hold-position of an electronic component in which the component is held by an electronic-component holding apparatus, an electronic-component holding apparatus having a hold-position detecting device, and an electronic-component mounting apparatus for mounting an electronic component on a printed-circuit board. The above method includes the steps of emitting light beams in a direction toward the electronic component (W) held by the electronic-component holding apparatus (58, 70), so as to take a projection of the component, and of detecting a position of the projection, thereby detecting the hold-position of the component.

Abstract: A method of taking an electronic component or chip out of each of plural pockets which are formed at regular intervals along a longitudinal direction of a carrier tape and which have openings in the upper surface of the tape, through vacuum suction of a suction member, while the tape is intermittently fed in a feeding direction parallel to its longitudinal direction, including the steps of: (a) bringing the pockets having the chips, into a position where their openings are covered with a covering device having a notch with a width narrower than that of the chip and wider than that of the suction member; (b) feeding the tape by the regular interval in the feeding direction, and permitting a leading chip of the chips covered with the covering device to be brought into a suction position where the leading chip is right below the suction member and the notch; (c) lowering the suction member through the notch so as to allow the suction member to suck and hold the leading chip; (d) retracting the covering device wh

Abstract: Method and apparatus for holding an electronic component prior to its placement on a circuit substrate. The component sucked by a sucker is first centered in one direction by closing movements of a first pair of opposed positioning members toward the component, and then centered in another direction normal to the above one direction by closing movements of a second pair of opposed positioning members which occur only after the first pair of positioning members are opened. The first pair of positioning members are provided on an assembly holding the sucker, and the second pair of positioning members are provided on the sucker holder assembly or separately from the sucker holder assembly. In the latter instance, the assembly holding the sucker and the first pair of positioning members are adapted to be movable relative to the separately provided second pair for alignment of the sucker with the separate second pair.
