Abstract

PURPOSE: To form the hand-held disc top calculator less in the frequency of cell replacement, by combining C-MOS, LD and printer (energy consumption, less than 1.5 joule).
CONSTITUTION: When C-MOS as the operation control element and LD as display element are combined, the low power consumption as shown in Table 50 is realized. On the other hand, as a printer, no power consumption at the waiting state where no printing is made, and low voltage (6 volts) driving by cells, have already been developed to reduce the energy consumption per one print line. Thus, by combining C-MOS, LD2 and low power consumption type printer 1, the hand-held calculator 100 longer in the cell life can be obtained. The calculator includes the cells of UM-3 type, keys 5, and printed circuit board and recording paper.
