Abstract:
1. A calculator having a timer function, comprising: a housing; a display disposed on the housing; a plurality of function keys disposed on the housing; a plurality of numeral keys disposed on the housing; a first processing section disposed in the housing for performing calculation functions; a second processing section disposed in the housing for performing timer programming and time keeping functions; and a switching section coupled to the first and second processing sections and coupled to at least the numeral keys, the switching section having a first switching state in which it forwards signals from the numeral keys to the first processing section and a second switching state in which it forwards signals from the numeral keys to the second processing section; wherein the first processing section receives signals from the numeral keys via the switching section, receives signals from at least some of the function keys, generates calculation results based on the received signals, and displays calculation results on the display; and wherein the second processing section receives signals from the numeral keys via the switching section, receives signals from at least some of the function keys, sets a time interval for each event based on the received signals, keeps track of a total elapsed or remaining time, a current event number, and an elapsed or remaining time of a current event based on a clock signal and the time interval value, and displays them on the display.
