Patent ID: 7591429

Claim:
A calendar providing system with a function of registering and regenerating contents, comprising: a contents registration/regeneration apparatus connected to a device via a network comprising: a registration unit which, in response to receiving digital contents and corresponding date information from the device, registers the contents in association with the corresponding date information in a database, wherein the date information uniquely identifies at least one of a year, month, and day to be associated with each of the registered contents, and a regeneration unit which, in response to receiving the date information from the device after the contents are registered, transmits the registered contents to the device, the registered contents being regenerated before or after being transmitted to the device; and a calendar generation apparatus comprising: a two-dimensional registration code issue unit which issues a two-dimensional registration code in which is embedded: access destination information causing the device to access the registration unit via the network, and the date information, a two-dimensional regeneration code issue unit which issues a two-dimensional regeneration code in which is embedded access destination information causing the device to access the regeneration unit via the network, and a print unit which prints a calendar in which the two-dimensional registration code and the two-dimensional regeneration code are printed in an area of the calendar corresponding to the at least one of a year, month, and day uniquely identified in the date information, wherein the date information received by the registration unit and regeneration unit from the device are each obtained by the device as a result of optically reading the two-dimensional registration code and the two-dimensional regeneration code from the calendar, respectively.
