Claim 7

An image display device according to claim 1 , wherein said display control means carries out said automatic scroll process in a circular manner by connecting a trailing end and a leading end of said basic image data to each other.

Claim 8

An image display device according to claim 1 , further including: basic data storage means for storing said data input from said input means as basic data; unit image data-forming means for outputting unit image data corresponding to sad basic data; and basic image data-forming means for arranging said unit image data corresponding to said basic data, which is outputted from said unit image data-forming means, in an area for said basic image data within said basic image data storage means to thereby form said part or whole of said basic image data.

Claim 9

An image display device according to claim 1 , further including scroll image data storage means for storing therein, at any given time point during execution of said automatic scroll process, a portion of said basic image data within a scrollable range including said display range at said any given time point and a range to which said display range can be shifted within a predetermined unit time period from said any given time point, as scroll image data for use at said any given time point, and wherein said display control means converts a portion of said scroll image data in said display range to display image data and display said display image data at said any given time point on said display screen during said execution of said automatic scroll process, and reads out said scroll image data for use at said any given time point from said basic image data storage means to store said scroll image data in said scroll image data storage means by said any given time point.

Claim 10

An image display device according to claim 1 , further including; basic data storage means for storing said data input from said input means as basic data; unit image data-forming means responsive to inputting of various kinds of data the reto for outputting unit image data corresponding to said various kinds of data input thereto; scroll image data storage means for storing the rein, at any given time point during execution of said automatic scroll process, a portion of said basic image data within a scrollable range including said display range at said any given time point and a range to which said display range can be shifted within a predetermined unit time period from said any given time point, as scroll image data for use at said any given time point; and basic image data-forming means for arranging said unit image data corresponding to said basic data, which is outputted from said unit image data-forming means, in an area for said basic image data within said basic image data storage means, and forming said scroll image data for use at said any given time point before said predetermined time period from said any given time point, said display control means converting a portion of said scroll image data in said display range to display image data and display said display image data at said any given time point on said display screen during said execution of said automatic scroll process, and reading out said scroll image data for use at said any given time point from said basic image data storage means to store said scroll image data in said scroll image data storage means by said any give time point.

Claim 11

An image display device according to claim 1 , wherein said basic image data is print image data to be printed on a print material.

Claim 12

An image display device according to claim 10 , wherein said print material is in the form of a tape.

Claim 13

An image display device according to claim 1 , wherein said change command means further includes stop command means for inputting a stop command for temporarily stopping said automatic scroll process.

Claim 14

An image display device according to claim 1 , wherein said size of said basic image data is represented by a number od dots in a direction of width of an image represented by said basic image data and said size of said display image data is represented by a number of dots in a direction of width of an image represented by said display image data.
