Abstract

PURPOSE:To realize a quick decision for the state of shift with a locked keyboard and to avoid the malfunction, by using a liquid crystal display matter, a substrate that contains the input and output lines of keys plus a hole drilled under the area where the keys are disposed, and a transparent key. CONSTITUTION:A liquid crystal keyboard consists of a liquid crystal display matter 15, a substrate 13 containing the input and output lines 10 and 11 of keys plus a hole drilled under the area where the keys are disposed, and a transparent character key 7. When an alphanumeric mode is desired on the keyboard, a shift key 5(alphanumeric) is pushed and released; while a shift key 4(Japanese syllabary) is pushed and released when a KANA mode is required for instance. Thus only the alphanumeric and KANA are displayed on the keyboard. As a result, whether the keyboard is locked to a shift state can be quickly known to eliminate the malfunction.
