PURPOSE:To obtain an optional number of advance stages and an optional waveform to the stage advance action of an operation mechanism, by changing the stage advance interval of optical signal control at an optical signal control part to the stage advance interval of the operation mechanism. CONSTITUTION:An optical signal control part 12 turns on and off the 1st optical signal group 11a in response to the stage advance action of an operation mechanism and generates the 2nd optical signal group 12a. An output control part 14 delivers the 2nd electric signal 14a in response to a binary signal produced from the 1st electric signal 13a. The modes of hatching parts A-D of the group 12a are generated with the binary optical signal control at the part 12 which works in response to the stage advance action of the operation mechanism. In other word, the stage advance interval of the binary optical signal control of the part 12 is changed to the stage advance interval of the operation mechanism. Thus it is possible to obtain more number of advance stages than conventional and to obtain easily an optional pattern signal. |
