Abstract
An entire electronic accounting and controlling system for a franking machine is mounted on two connected printed circuit boards, one along the top of the machine and the other along one side of the machine within the machine casing. The top board carries four rotary encoding switches and press button switches which are scanned by signals from a microcomputer on the side board passing to a binary counter controlling a binary to decimal decoder to send multiplexed signals to the switches enabling the rotary switches to send four pairs of five-bit words along ten scanning lines to the microcomputer which delivers equivalent eight-bit error immune signals to duplicate non-volatile memories. The press button switches send signals along the scanning lines to enable a display module on the top board to display decimal digits according to the information stored in the memories. A printing drum is set mechanically simultaneously with the rotary switches. When a sealed door in the casing is opened a switch is automatically actuated to change over from customer mode to Post Office mode.
