摘要： A ratchet device is disclosed which includes a body, a ratchet wheel rotatably supported by the body, a feed pawl having an engaging portion engageable with teeth of the ratchet wheel, a support member for holding the feed pawl, a member for biasing the feed pawl toward the wheel teeth, and a drive device for moving reciprocating the support member between two positions to place the feed pawl alternately in its fully advanced and retracted positions, so as to rotate the ratchet wheel a predetermined angle in one direction. The ratchet device further includes a stopper member for contact with the feed pawl when the pawl is placed in the fully retracted position, to thereby prevent the engaging portion of the pawl from disengaging from the teeth of the ratchet wheel. Further, the engaging portion of the feed pawl is shaped so that it engages mutually opposed faces of the ratchet wheel when the feed pawl is in contact with the stopper member, to thereby lock the ratchet wheel against clockwise and counterclockwise rotations thereof. Also disclosed is a tape feeding apparatus which utilizes the ratchet device.

摘要： 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.

摘要： 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.
