Abstract
In a method for positioning a medium carrying device at a desired one of processing sections which are provided on a base frame in a designed arrangement, an error between a designed position and a reference position is detected for each of three predetermined sections. Based on detected errors of the predetermined sections, a corrective value is calculated for each of the processing sections. The medium carrying device is carried and positioned at a desired processing section using a corrective value of the desired processing section.
Claims14
A method for positioning a medium carrying device at a desired one of processing sections which are provided on a base frame in a designed arrangement, comprising the steps of:
- a) selecting at least three predetermined sections which are two-dimensionally arranged on the base frame;
- b) detecting an error between a designed position and a reference position for each of the predetermined sections, where the designed position is an actual position to which the medium carrying device is moved in each of the predetermined sections according to the designed arrangement and the reference position is a predetermined position in each of the predetermined sections;
- c) calculating a corrective value for each of the processing sections based on detected errors of the predetermined sections;
- and
- d) positioning the medium carrying device at a desired processing section using a corrective value of the desired processing section.
A system for positioning a medium carrying device at a desired one of processing sections which are provided on a base frame in a designed arrangement, comprising:
- an error detector for detecting an error between a designed position and a reference position for each of at least three predetermined sections which are two-dimensionally arranged on the base frame, where the designed position is an actual position to which the medium carrying device is moved in each of the predetermined sections according to the designed arrangement and the reference position is a predetermined position in each of the predetermined sections;
- a corrective value calculator for calculating a corrective value for each of the processing sections based on detected errors of the predetermined sections;
- and
- a controller for carrying and positioning the medium carrying device at a desired processing section using a corrective value of the desired processing section.
An automatic information medium carrying system for carrying an information medium from a processing section to another in a plurality of cabinets which are connected in series, each cabinet containing a pair of base frames each fixing a plurality of storage cells in a designed arrangement, each of the storage cells being designed to store an information medium, comprising:
- an error detector for detecting an error between a designed position and a reference position for each of at least three predetermined storage cells which are two-dimensionally arranged on each base frame, where the designed position is an actual position to which a medium carrying device is moved in each of the predetermined storage cells according to the designed arrangement and the reference position is a predetermined position in each of the predetermined storage cells;
- a corrective value calculator for calculating a corrective value for each of the storage cells based on detected errors of the predetermined storage cells;
- and
- a controller for carrying and positioning the medium carrying device at a desired storage cell using a corrective value of the desired storage cell.
