Title:
METHOD AND APPARATUS FOR LOCKING RECORDING PAPER
Document Type and Number:
Japanese Patent JPS5319856
Kind Code:
A
Abstract:
In a measuring instrument such as a spectrophotometer which is driven under the control of a dedicated microcomputer and has a provision for wavelength scan, a flow chart lock system is obtained by storing in the random access memory of the microcomputer an indication of the actual chart position between two sprockets on the chart drive. With this information and stored data regarding the position of the scanning apparatus of the instrument, accurate repositioning of the chart to accurately reflect the scanning position even after scale changes or different modes of operation have occurred is accomplished.
