An information transmitting system for use in a factory, which is capable of transmitting information among controllers simply without the complicated lead-around of a communication line nor the need of complicated communication protocol. A controller for every molding cell Ai, where i&equals;1,2 . . . max and max is a maximum number of molding cells, a conveyance controller to control an automatic conveyor, a stock cell and a centralized controller are connected to each other via an Ethernet line to provide a common information storage unit, and information is transmitted among the controllers through the common information storage unit. Since there is no need of parallel communication lines between the controllers, an I/O port or a communication line may be prevented from increasing in number and the lead-around of the communication line is prevented from being complicated, resulting in a reduction of cost required for setting up the devices.
