a mechanism that has a forwardly and reversely rotatable motor
that generates power to switch operating modes.
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. A mode discriminating method for discriminating the
operating mode of a mechanism having a forwardly and reversely
rotatable motor for generating power to switch operating
modes, said method comprising the steps of:
detecting at least one switching signal according to a
switched mode of said mechanism;
detecting a motor rotation signal indicative of the
rotating direction of said motor; and
combining said switching signal and motor rotation signal
in a control circuit to determine the switched mode of said
mechanism.
