IPC: G06F3/12
Filed: 1990-03-05
Abstract: PURPOSE:To facilitate the registration and conformation of recording relating information for recording a color component, etc., by receiving the name of the recording relating information used for recording with the character-string information at the time of recording, and extracting the corresponding recording relating information from a storage means by retrieving a keyword, based on the received character-string information. CONSTITUTION:A storage means 100 stores in advance plural pieces of recording relating information, and also, character-string information for showing the name of its recording relating information. A retrieving means 200 receives the name of the recording relating information used for recording by the character-string information, and extracts the corresponding recording relating information from the storage means 100 by retrieving a keyword, based on the received character-string information. That is, the recording relation information used for recording is read out of the storage means 100 by retrieving the keyword by the name without designating an address. In such a manner, the storage contents of the storage means 100 can be recognized easily by a user, and also, it is unnecessary to fix in advance the housing address of the recording relating information, therefore, the device can be easily manufactured.
