Abstract

PURPOSE: To improve manipulation by providing one key with at least two functions that two keys have.
CONSTITUTION: At the bottom of a miniature typewriter, key K with both the functions of electric power switch SW1 and paper feed switch SW4. For the purpose, key K couples with switches SW2 and SW3 and depressing key K turns on both SW2 and SW3. With SW2 on, the voltage of electric power battery VA is applied to load L while the charge of capacitor C2 flowing from the base of transistor TR1 to the emitter by way of resistance R2, so that the electronic typewriter will operate as if SW1 were turned on. With SW3 on, heat-sensitive paper is fed since SW3 and SW4 are connected in parallel, but once C2 is completely discharged via R2, TR1 turns on to stop the application of the voltage to load L. Namely, a certain time after key K is turned on, load L is placed in the same state that key K is set free.
