ABSTRACT:
The present invention increases the information-setting capability of an electronic pen by using exchangeable cartridges, each cartridge having a pre-installed information setting. The wiring of each cartridge is differentiated to designate information such as, for example, color or line width. The cartridge attributes may specify the stored information such as, for example, color. A cartridge may include a password or other specific ID of an individual. Both mechanical contact points and non-mechanical contact points can be used to actualize a cartridge. In addition, a rechargeable battery can be placed inside a cartridge, and the battery may be recharged using a battery recharging device. Information may be written and rewritten to a memory storage device inside a cartridge by connecting the cartridge to a separate writing device.
