PORTABLE ARITHMETIC PROCESSOR

摘要

PURPOSE:To secure the improvement of operation efficiency and the reduction of a work area when a manuscript is inputted by using the portable arithmetic processor which has a foldable display part. CONSTITUTION:An arithmetic processing part 2 and a keyboard input part 1 are integrated in one body and those parts and the display part 4 are coupled through a hinge 3. Plural crosspiece members 8a, 8b, and 8c which are normally stored in a display part cover 7 are drawn out to information (A) and fixed while the display part 4 is in use. Similar effect is obtained by sliding part of the back surface plate itself of the display cover 7 or rotating it on its upper part as a support axis instead of the crosspiece members 8a, 8b, and 8c.
