  "abstract": "A device picker in a handler includes a vertical plate installed on the installation rest to be movable, a plurality of variable pitch blocks installed in parallel with each other on a lower end of the vertical plate through guide members to be movable in right and left directions to enable right/left pitch adjustment, a pair of pickup members installed on front and rear sides of each of the variable pitch blocks through guide members to ascend/descend, respectively, the pickup members coupled with each other to interoperate in opposite directions to pick up and release the devices alternately, a block driving means for moving the variable pitch blocks in a lateral direction, and a pickup member driving means for interoperating the pickup members to move upward and downward in opposite directions, respecively.",
  "claims": [
    "1. In an apparatus mounted an installation rest installed on a body of a handler to move horizontally to pick up to transport devices from one side of the handler to the other side of the handler, a device picker in the handler, comprising: a vertical plate installed on the installation rest to be movable; a plurality of variable pitch blocks installed in parallel with each other on a lower end of the vertical plate through guide members to be movable in right and left directions to enable right/left pitch adjustment; a pair of pickup members installed on front and rear sides of each of the variable pitch blocks through guide members to ascend/descend, respectively, the pickup members coupled with each other to interoperate in opposite directions to pick up and release the devices alternately; a block driving means for moving the variable pitch blocks in a lateral direction; and a pickup member driving means for interoperating the pickup members to move upward and downward in opposite directions respectively.",
    "2. The device picker of claim 1, the block driving means comprising: an electric motor installed on the vertical plate; a pinion gear unit coupled with the electric motor to revolve; and a rack gear unit fixed to an upper end of the variable pitch block to gear into the pinion gear unit to move straight in the lateral direction.",
    "3. The device picker of claim 2, the pickup member driving means, comprising: driving and driven pulleys installed at upper and lower ends of one side of each of the variable pitch blocks to revolve, respectively; an electric motor revolving the driving pulley; a belt coupled across with the driving and driven pulleys to be driven upward and downward by revolution of the driving pulley; a front connecting bracket having one end coupled with one side of the belt and the other end coupled with the pickup member in the front side; and a rear connecting bracket having one end coupled with the other side of the belt and the other end coupled with the pickup member in the rear side.",
    "4. The device picker of claim 2, wherein a vacuum nozzle absorbing a device surface by vacuum pressure is formed at a lower end of each of the pickup members.",
    "5. The device picker of claim 1, the pickup member driving means, comprising: driving and driven pulleys installed at upper and lower ends of one side of each of the variable pitch blocks to revolve, respectively; an electric motor revolving the driving pulley; a belt coupled across with the driving and driven pulleys to be driven upward and downward by revolution of the driving pulley; a front connecting bracket having one end coupled with one side of the belt and the other end coupled with the pickup member in the front side; and a rear connecting bracket having one end coupled with the other side of the belt and the other end coupled with the pickup member in the rear side."
