A power transmission apparatus includes a shaft, a driving plate, a first driven plate, and a sensor device. The driving plate is disposed on the shaft and rotates with the shaft. The driving plate includes a first block that has a driving surface on it. The first driven plate is disposed on the shaft and capable of moving along the shaft. The first driven plate includes a second block that has a driven surface corresponding to the driving surface. The sensor device is disposed close to the first driven plate for detecting the movement of the first driven plate along the shaft. When the shaft rotates together with the driving plate, the driving surface compels the driven surface to rotate and simultaneously move away from the driving plate along the shaft, and the movement along the shaft is detected by the sensor device.
