摘要： PROBLEM TO BE SOLVED: To provide an electronic mail receiving device for displaying a received mail which should not be viewed by others after working it according to a preliminarily designated rule. SOLUTION: A mail transfer data controlling part 13 detects a received mail matched with a condition preserved in a keyword information list 19 from among received mails transferred from a mail server computer 8 to a mail receiving part 14, and works the detected received mail according to a rule preserved in the keyword information list 19. All received mails including the worked received mail are stored in a mail storage place 21 for display by a mail receiving part 14, and displayed for a user by a data displaying part 15. When a display mode preserved in a display mode preserving place 20 is a secret mode, the worked received mail is displayed in a format which can not be recognized by a third person.

摘要： PROBLEM TO BE SOLVED: To reduce a data amount of Huffman tree information by coding each code using a Huffman code table generated by each code incidence frequency in a data file. SOLUTION: A data file arranging codes representing characters and a Huffman coding data file after data compression are stored in a storage device 3. A Huffman coding processing and decoding processing program is stored in a ROM 4 and various data arrays generated and used for coding decoding processing and data table write areas are reserved in a RAM 5. Then a data area storing the number of types of codes incident in a data file before compression, 1st data arrays in which incidence codes are arranged in the order of incidence frequency, 2nd data arrays where data areas storing the number of types of the same bit length Huffman codes are arranged in the order of Huffman code bit length are compressed as Huffman tree information and arranged to a head of the data file, codes not incident area deleted from the tree information to reduce the tree information data amount.
