Thus an intermediate character pattern is used as the pattern 5 for the similar characters which may possibly be misrecognized. As a result, the characters are never misrecognized and the character code corresponding to the pattern 5 is automatically changed in response to the change of the input mode. Then the writer can surely deliver his/her desired characters and therefore the stable input of characters is secured.

Title: Hand-free circuit for portable telephone set
Inventor: KOSAKA MASAAKI
IPC: H04M1/60
Filed: 1991-08-23
Abstract: PURPOSE:To prevent malfunction of changeover between the transmission mode and the reception mode by continuing the just preceding operating mode when both a transmission voice signal and a reception voice signal are detected by a comparator. CONSTITUTION:When the state transits from the state of the transmission mode having only a transmission voice signal into the state in which both a transmission voice signal and a reception voice signal are in existence, a sequence circuit 41 sends a control signal to only a 2nd attenuator 17 so that it is in operation so as to keep the transmission mode being the just preceding operating mode. When the state transits to the state in which only the reception voice signal remains, the sequence circuit 41 sends a control signal to a 1st attenuator 11 that it is in operation so as to keep the reception mode. Thus, even when bypassing of the reception voice signal from a speaker to the microphone or bypass of the transmission voice signal to the receiver side at a base station takes place, malfunction of the changeover of the operating mode is prevented.
