Abstract

An electronic device is disclosed that can scroll a display screen displayed by means a display apparatus thereon in line units as well as in page units by means of operating only the up and down cursor keys. With this electronic device, a mode setting means sets a page scroll mode in order to scroll the display screen by page units if a predetermined operation is performed with at least one of either the up cursor key or the down cursor key. A determination means determines whether or not the page scroll mode has been set when only one of either the up cursor key or the down cursor key has been operated. A scrolling means both scrolls the display screen in page units in the direction of the up cursor key or down cursor key that was operated if the determination means determines that the page scroll mode has been set, and resets the page scroll mode.

Claims

1. An electronic device having a display apparatus, and an up cursor key and a down cursor key for moving a cursor displayed on the display apparatus and scrolling a display screen displayed in the display apparatus in line units, comprising:

mode setting means that sets a page scroll mode in order to scroll the display screen by page units if a predetermined operation is performed with at least one of either the up cursor key or the down cursor key;

determination means that determines whether or not the page scroll mode has been set when only one of either the up cursor key or the down cursor key has been operated; and

scrolling means that both scrolls the display screen in page units in the direction of the up cursor key or down cursor key that was operated if the determination means determines that the page scroll mode has been set, and resets the page scroll mode.

2. The electronic device according to claim 1, wherein the setting means sets the page scroll mode if the up cursor key and the down cursor key are simultaneously operated.

3. The electronic device according to claim 1, wherein the setting means sets the page scroll mode if at least one of the up cursor key or the down cursor key has been operated for more than a predetermined period of time.

4. The electronic device according to claim 1, wherein the setting means sets the page scroll mode if at least one of the up cursor key or the down cursor key has been operated a predetermined number of times.

5. The electronic device according to claim 1, wherein the up cursor key and the down cursor key are located apart from each other, and the setting means sets the page scroll mode if the region between the up cursor key and the down cursor key is operated.

6. The electronic device according to claim 1, further comprising an image forming unit for forming an image on a transfer material.

7. A storage medium which stores a control program which is executed by an electronic device having a display apparatus, and an up cursor key and a down cursor key for moving a cursor displayed in the display apparatus and scrolling the display screen displayed in the display apparatus in line units, said control program causing the electronic device to execute:

mode setting means that sets a page scroll mode in order to scroll the display screen by page units if a predetermined operation is performed with at least one of either the up cursor key or the down cursor key;

determination means that determines whether or not the page scroll mode has been set when only one of either the up cursor key or the down cursor key has been operated; and

scrolling means that both scrolls the display screen in page units in the direction of the up cursor key or down cursor key that was operated if the determination means determines that the page scroll mode has been set, and resets the page scroll mode.
