Portable radio information terminal, screen scroll method, recording medium and microcomputer

A portable radio information terminal, comprising:

• radio communication means;
• control means for at least performing data processing;
• image displaying means including a screen for scrolling up and down an image displayed on said screen by at least one line, wherein said control means at least displays information extracted from a radio electric wave received by said radio communication means from a transmitter on said image displaying means;
• input means including a freely operatable operation unit for generating a plurality of upward scroll command signals and a plurality of downward scroll command signals resulting from an operation performed on said input means;
• unprocessed-signal detecting means for detecting a plurality of unprocessed upward scroll command signals and a plurality of unprocessed downward scroll command signals among said plurality of upward scroll command signals and said plurality of downward scroll command signals generated by said freely operatable operation unit;
• screen moving-up means for shifting up said image displayed on said screen by a number of lines equal to a number of said plurality of unprocessed upward scroll command signals;
• screen moving-down means for shifting down said image displayed on said screen by a number of lines equal to a number of said plurality of unprocessed downward scroll command signals;
• and
• display control means for at least counting said number of unprocessed upward scroll command signals and said number of unprocessed downward scroll command signals and driving said screen moving-up means for said plurality of upward scroll command signals and driving said screen moving-down means for said plurality of downward scroll command signals.

A recording medium, comprising:

• means for storing a plurality of programs fetched for execution by a computer, wherein said plurality of programs include at least
• unprocessed-signal detecting means for detecting a plurality of unprocessed upward scroll command signals and a plurality of unprocessed downward scroll command signals among a plurality of upward scroll command signals and a plurality of downward scroll command signals requesting a scroll-down operation and a scroll-up operation, respectively, of an image displayed on a screen,
• screen moving-up means for shifting up said image displayed on said screen by a number of lines equal to a number of said plurality of unprocessed upward scroll command signals
• screen moving-down means for shifting down said image displayed on said screen by a number of lines equal to a number of said plurality of unprocessed downward scroll command signals and
• display control means for at least counting said number of said plurality of unprocessed upward scroll command signals and said number of said plurality of unprocessed downward scroll command signals and driving said screen moving-up means for said plurality of upward scroll command signals and driving said screen moving-down means for said plurality of downward scroll command signals.

A microcomputers comprising:

• an embedded central processing unit;
• embedded storage means for storing a plurality of programs fetched and executed by said embedded central processing unit;
• embedded data transfer means used for connecting at least said embedded central processing unit to said embedded storage means, wherein said embedded data transfer means can be connected to external equipment;
• and
• means for providing a function for transmitting a signal based on a processing result output by said embedded central processing unit to said external equipment by one of radio communication and a wire connection,
• wherein said plurality of programs stored in said embedded storage means at least include
• unprocessed-signal detecting means for detecting a plurality of unprocessed upward scroll command signals and a plurality of unprocessed downward scroll command signals among a plurality of upward scroll command signals and a plurality of downward scroll command signals requesting a scroll-down operation and a scroll-up operation, respectively, of an image displayed on a screen
• screen moving-up means for shifting up said image displayed on said screen by a number of times equal to a number of said plurality of unprocessed upward scroll command signals,
• screen moving-down means for shifting down said image displayed on said screen by a number of times equal to a number of said plurality of unprocessed downward scroll command signals and
• display control means for at least counting said number of said plurality of unprocessed upward scroll command signals and said number of said plurality of unprocessed downward scroll command signals and driving said screen moving-up means for said plurality of upward scroll command signals and driving said screen moving-down means for said plurality of downward scroll command signals.
