| Claim: | What is claimed is |
| Claim: | 1. A stick feeder, comprising |
| Claim: | an elongated stick for housing and carrying a series of workpieces; |
| Claim: | a holding block for receiving and holding the workpieces sequentially discharged from the stick, a workpiece holding portion of said holding block being adjustable in a direction perpendicular to a feeding direction of said workpieces; and |
| Claim: | a holder mounted adjacent said holding block |
| Claim: | a stop member for stopping the workpieces fed from the stick to the holding block mounted detachably to said holder, a mounting position of said stop member with respect to the holder being changeable so that a stopping position of the workpieces can be adjusted at the workpiece holding member in accordance with the change of the mounting position |
| Claim: | said holder comprising an axial insertion hole, a slot open to an outer periphery of the holder and extending in the axial direction of the insertion hole, said slot communicating with said insertion hole, with at least one end thereof being open; and a plurality of radial slots open to the outer periphery of the holder and communicating with said insertion hole and with said axial slot, said radial slots being spaced axially along said axial slot: and |
| Claim: | said stop member comprising a stop portion adapted to be inserted into said insertion hole and to protrude toward said stick; an arm protruding radially from an outer peripheral surface of said stop portion and selectively insertable into and engagable with one of said radial slots through said axial slot; |
| Claim: | the mounting position of said stop member to said holder thus being variable to vary the stop position of the workpieces. |
| Claim: | 2. The stick feeder according to claim 1, wherein |
| Claim: | said holding block is formed of a pair of divided blocks which can close toward and separate away from each other in a direction perpendicular to the carrying direction of the workpieces. |
| Claim: | 3. The stick feeder according to claim 2, wherein |
| Claim: | the divided blocks can close and separate by means of screw and nut assembly with the nuts rotatable in opposite directions on rotation of the screw. |
| Claim: | 4. The stick feeder according to claim 1, comprising a number of stop members having stop portions of different lengths in the direction of protrusion. |
| Claim: | 5. The stick feeder according to claim 1, wherein: said workpieces are semiconductor devices. |
