A tape take-up for taking up a tape, including a first member having a first friction surface; and a second member including a drum portion for taking up the tape, and having a second friction surface, the drum portion having an axis line, at least one of the first and second friction surfaces including an annular friction surface concentric with the drum portion, the first and second members being combined with each other such that the first and second members are rotatable relative to each other about the axis line of the drum portion while the first and second friction surfaces are held in contact with each other, one of the first and second members including a permanent magnet, the other of the first and second members including a magnetic portion formed of a magnetic material, the permanent magnet and the magnetic portion having respective shapes which ensure that the permanent magnet and the magnetic portion are opposed to each other at any relative angular phase between the first and second members, the permanent magnet exerting, to the magnetic portion, a magnetic attraction force which causes the first and second friction surfaces to be held in contact with each other while the second member is not subjected to an external force greater than the magnetic attraction force, the magnetic attraction force permitting the second member to be separated from the first member when the second member is subjected to the external force.

Tape take-up and cover-tape take-up apparatus

An electronic-component supplying cartridge is provided which includes a movable and an immovable jumping-out-preventing member and is free from jumping of electronic components out of electronic-component accommodating pockets, changing of posture of the components, or standing-up of the components due to suction. A shutter 210 is attached to a cover 82 fixed to a cartridge frame, such that the shutter 210 is movable relative to the cover 82 in the tape feeding direction. The shutter 210 includes a connection portion 214 having a groove 222 opening at a downstream-side end thereof as seen in the feeding direction, and a pair of movable jumping-out-preventing strips 228. When the shutter 210 is moved to a second position thereof, the strips 228 are received in receiving recesses 200, respectively. When a component carrier tape is fed, the shutter 210 is moved to a first position thereof where the strips 228 cover a component accommodating pocket fed to an electronic-component picking-up position. A component-suction nozzle is moved downward in synchronism with the retracting movement of the shutter 210 to the second position, so that the nozzle holds by suction an electronic component through the groove 222 before completion of the retracting movement of the shutter 210. Since the component is not freed before being held by the nozzle, the component does not jump out of the carrier tape.

Electronic-component supplying cartridge and electronic-component

An electronic-component supplying system including electronic-component supplying cartridges each of which supplies each of electronic components, a support table to which the cartridges are attachable and which has a support surface for supporting the cartridges attached to the support table, a positioning device which positions each cartridge attached to the support table, on the support surface, and a preventing device which prevents each cartridge attached to the support table, from moving apart from the support surface, the positioning device including one or more first positioning projections provided on one of the support table and each cartridge, one or more first positioning grooves provided on the other of the support table and each cartridge, such that the first positioning groove extends in a first direction and is engageable with the first positioning projection to position the first positioning projection in a second direction perpendicular to the first direction while permitting the first positioning projection to be moved relative thereto in the first direction, and a stopper which defines a limit of movement of each cartridge relative to the support table in the first direction.

Electronic-component supplying system

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 of different values.
