Abstract

A plurality of memories are provided for respectively storing a series of distance information measured by extending the length of an extensible tape member which is attached to the length of an object to be measured. The memory is selected through the use of an N-nary counter and a decoder which are activated by both a memory key and a free key. A memory recall key is provided for indicating the distance information contained in the selected one of the memories in a display. An illumination lamp is employed for showing whether the distance information is appropriately stored in the selected memory. A CPU (central processor unit) is provided for controlling the distance information to provide a visual indication corresponding to the distance information in the display. The distance information is canceled through the use of a clear key, the distance information being stored in an up/down counter for counting signals responsive to pull-out and pull-in movement of the extensible tape member out and into the housing of combined electronic digital scale and calculator. A memory clear key is activated for canceling the memorized distance information in the memory.
