Abstract
PURPOSE: To realize a multifunction and compact keyboard which can be folded, by using both sides of a substrate as a keyboard.
CONSTITUTION: With regard to the keyboard of an electronic desk-top calculator, etc., a frequently-used part is included in the 1st keyboard on the front surface and keys for a program are arranged at one part of folding substrate 2 that faces forth in use. Keys for putting other functions (e.g.clocking) in normal use are arranged on the side that of substrate 2 faces forth when this is not used as the electronic desk- top calculator. It is recommended to constitute the keyboard parts in one sheet of a both-side printed circuit substrate. Consequently, the multifunction keyboard can be made easy to use and compact.
