A document storage unit stores, as a type of a document element in a document, an element sequence in which a text element which is a document element for text and an image element which has a server character image acquired from the server as a view, has a character code value as an attribute, and is dependent on a platform are mixed. When a copy operation on a screen is determined, a copy processing unit reads character codes from the text element and the image element stored in the document of a copy source, generates copy source character sequence data, and stores the data in a copy buffer. When a paste operation is determined subsequent to the copy operation, a paste processing unit generates an element sequence including the text element and the image element from the copy source character sequence data stored in the copy buffer, and inserts the sequence to a document of a paste destination. In this course, the character image of the image element is acquired from the server.
