ABSTRACT:
To allow data to be exchanged between a printing drum and a stencil printing device main body in a highly adaptable manner with regard to the increase in the kinds of data to be transmitted without requiring any change in mechanical structures, light emitting devices 43, 65 and light receiving devices 45, 63 are arranged in mutually opposing parts of the printing drum 7 and the main body frame 1 to allow optical communication between them. Other modes of wireless communication may be used in place of the optical communication. This invention is particularly useful when the printing drum 7 is detachably mounted on a main body frame 1 of the stencil printing device, and the main control unit is required to adapt itself to different printing drums.
