A scanner used in offices and business establishments in combination with on-line deposit systems for reading magnetically recorded information and stated values of checks. Deposit or money-conversion procedures for checks, which conventionally had to be brought to the bank, can be easily handled on the spot, reducing time, labor, and energy usage losses. The mound shape that rises from the check insertion slot to the rear improves the insertability of checks, supporting smooth paper feeding to the scanner unit. The innovative mound shape evolved naturally from functionality, and expresses the innovativeness of this equipment and system.
