A drive base which is utilized in conjunction with a postal mailing system is disclosed. The base comprises a mode selection arrangement which alternately actuates a postage metering unit or a tape drive unit located within a mailing machine. The arrangement also provides a neutral setting for the drive base. Thus, in the neutral position, the drive base prevents the meter unit or the tape drive unit from operating. The mode selection arrangement includes a first cam member for engaging either the metering unit or the tape drive unit for operation. The arrangement also includes a second cam member for preventing one of the units from rotating when the other is engaged. In addition, the second cam member prevents both units from moving when the system is in a neutral position. This base provides a simple apparatus to be utilized for actuating the various portions of a postal mailing system.
