Abstract
A linear rotary mechanism includes: a pair of elongated guide rails in parallel to each other: a linear motor having a tubular primary side slidably disposed on the guide rails and a shaft-shaped secondary side coaxially extending into an internal hole of the tubular primary side, the shaft-shaped secondary side being axially linearly reciprocally movable along the tubular primary side; and a rotary motor fixedly disposed on the guide rails and connected with one end of the shaft-shaped secondary side. Accordingly, the rotary motor is linearly reciprocally movable along the tubular primary side in synchronism with the shaft-shaped secondary side and the guide rails.
