Abstract
An image transmitting ball-point pen mainly consists of a battery compartment, a lower body, an extension tube and a tapered cap located at the terminal end of the extension tube which serves to fix a turning sleeve and an outer tube onto the extension tube. The turning sleeve has two slide grooves and a plurality of slots which are employed to contain the protrusions on the interior of the outer tube. The upper end of the transmitting plate is placed between two locating strips and the lower end of the transmitting plate extends downward to the locating grooves and the turning sleeve where it is locked by a lock pin passing through the slide channel and the locating grooves. When the outer tube is being turned, the turning action makes the transmitting plate a right or left movement as well as an up or down movement, so it further makes the ink cartridge which works as an antenna extending or retracting along the tapered cap.
