A data storage device includes a memory for storing fixed-form data such as schedule data and a memory for storing handwriting memory data. When a particular key is operated when a schedule is displayed, a memorandum input screen is opened on the display. The user is able to input memorandum data by handwriting on the input screen or read-out and display already stored memorandum data on the input screen. By operating a key displayed on the input screen, the written or read-out memory data can be stuck as a memorandum to the displayed schedule or its date.
