1. A system for generating control data comprising:

  • a movable member movable within a plurality of predetermined positions;

    position detecting means for detecting said plurality of predetermined positions of said movable member and outputting a respective position signal depending on the predetermined position of said movable member;

    converting means for converting each said position signal to a respective digital position signal, and for outputting said digital position signal corresponding to a current predetermined position of aid movable member as a read address, whereby said plurality of predetermined positions correspond to a plurality of read addresses;

    memory means for storing a plurality of control data in a range of respective read addresses therein, and for storing in a further memory area said read addresses from said converting means in a selected correspondence with said range of respective read addresses of said plurality of control data;

    writing means for writing into said further memory area, in an adjustment mode when said movable member is successively placed at said predetermined positions, each respective one of said read addresses when said movable member is at the respective predetermined positions, in said correspondence to the respective one of said read addresses of said memory means at which the respective control data is stored;

    interpolation means for interpolating, in said adjustment mode after said writing into said further memory area of said read addresses corresponding to said predetermined positions, between said read addresses of said memory means of said desired control data corresponding to said predetermined positions;

    reading means for reading out said control data from said read addresses of said memory means; and

    output means for outputting said control data read out from said memory means;

    wherein, after completion of an adjustment of said adjustment mode, a respective desired one of said control data is output for each predetermined position of said movable member.
