Abstract: A magnetic ink character reading apparatus, magnetic ink character reading method and program, and a POS terminal apparatus reduce recognition errors and thereby improve the read rate. The magnetic ink character reading apparatus reads a text string of magnetic ink characters using both a magnetic reading mechanism and optical reading mechanism to obtain magnetic ink character recognition (MICR) results and optical character recognition (OCR) results, which are compared. The OCR process is repeated if the results differ. The positions of the read character blocks are compared to find character blocks that are offset perpendicularly to the base line of the magnetic ink characters, and the OCR process is repeated. The area to which the OCR process is applied again is near the position of the offset character block corrected in the direction perpendicular to the line of magnetic ink characters to be in line with the character blocks for which the MICR result and OCR result were the same.

Abstract: A circuit analyzing apparatus for analyzing operation characteristics of a circuit unit in which, on a substrate, circuit devices are arranged, has a part for automatically obtaining a value of a substrate parameter concerning the substrate for an operating frequency, which value depends on the operating frequency; and a part for analyzing operation of the circuit unit based on the value of the substrate parameter for the operating frequency.

Abstract: A false act of a clerk at a store is monitored at a host computer under utilization of a communication network by detecting a false key operation in reference to a count which can be flexibly set in an item sales register or the like. The sales processing unit reads out in sequence the stored function numbers, collates them with the function numbers of the depressing limit in sequence, and if the result shows a coincided state, the sales processing unit adds 1 to the limit counter of the corresponding key, compares the value of the limit counter of the corresponding key with the corresponding limit count of the depressing limit master, and if the value of the limit counter exceeds the limit count, the sales processing unit outputs to the communication unit an instruction that the fact showing of the depressing action of the corresponding key exceeded the limit count is sent to the host computer, and causes the communication unit to send it.
