INFORMATION PROCESSOR AND INFORMATION INPUT METHOD

PROBLEM TO BE SOLVED: To input massive information with simple operation in spite of simple configuration. SOLUTION: On a rotary bezel 102 provided rotatably in respect to a barrel 101, information, which can be inputted by such a watch type information processor 100, is described. Then, the watch type information processor 100 has a reference detecting means for detecting the rotating angle and rotating direction of the rotary bezel 102 from a position (reference position) where ' ' is instructed as instruction mark 110 on the rotary bezel 102 as shown in the Figure. Besides, the watch type information processor 100 can input the other information except for information described on the rotary bezel 102. In this case, information is inputted corresponding to the rotations of the rotary bezel 102 from the start of a mode for inputting the other information. At such a time, the detection of rotations from the reference position due to the reference detecting means is continued as well and when a mode for inputting the information on the rotary bezel 102 is started as well, information can be inputted corresponding to the rotations from the reference position.
