PURPOSE: An electronic paper checker having an automatic marking function without a writing tool and a learning management function is provided to remove needs to directly check an answer to a printed problem collection, need no answer sheet offered to the problem collection, and keep constant paper check without receiving influence of the writing tool. CONSTITUTION: Keypad data received from a user is transferred to a system to perform multi-point control and operation. A value of the transferred keypad data is displayed to an LCD(Liquid Crystal Display) display(200) through an LCD driver(201) after being stored in a registry(202). A control/operation value of an MCU(Micro Controller Unit)(203) is transferred to an EEPROM(Electronically Erasable Programmable ROM)(208) and calculated value is compared with the data stored in the EEPROM. Compared data is inputted to a keypad(204) as the final value under control of the MCU and the final value is transferred to the EEPROM with an alarm(206) informing a user of input completion.
