Abstract
Individual keys necessary for operations are grouped into key groups according to their functions. Key groups which do not fall within a display block allotted for all the keys are further divided into sub-groups. Switching keys for switching to other sub-groups are added. An operator operates the switching keys to arrive at the intended key.

A display system, comprising:
- a touch panel that simultaneously displays a first key group and a second key group, the second key group including a product key and a first switching key, the first switching key switching a display to replace the second key group with a third key group on one display;
- a display switching unit that, in response to a pressed the first switching key, replaces the second key group with the third key group on the display of the touch panel so that the first key group and the third key group are simultaneously displayed;
- a key group master memory unit that stores key group master information for the first, the second, and the third key groups;
- a displayed key group attribute information storage unit, that stores, as displayed key group attribute information, the key group master information of the first, the second, and the third key groups that are being displayed on the display of the touch panel;
- and
- a operation key attribute obtaining unit that, in response to the pressed first switching key, obtains a link destination attribute and a link destination number in the displayed key group attribute information that corresponds to the first switching key, and outputs the link destination attribute and the link destination number to the display switching unit;
- wherein the display switching unit that, in response to receiving the link destination attribute and the link destination number from the operation key attribute obtaining unit, reads out from the key group master memory unit, the key group master information designated according to a received link destination attribute and a received link destination number in the displayed key group attribute information that corresponds to the pressed first switching key, and replaces only the second key group with the third key group corresponding to the key group master information designated according to the link destination attribute and the link destination number for display on the touch panel, and updates the displayed key group attribute information by replacing only the key group master information of the second key group with the third key group.

A display method, comprising:
- displaying a first key group and a second key group simultaneously, the second key group including a product key and a first switching key, the first switching key configured to switch a display to replace the second key group with a third key group on one display of a touch panel;
- replacing the second key group with the third key group on the display of the touch panel, in response to a pressing of the first switching key so that the first key group and the third key group are simultaneously displayed,
- storing key group master information for the first, the second, and the third key groups in a key group master memory unit;
- storing, as displayed key group attribute information, the key group master information of the first, the second, and the third key groups that are being displayed on the display of the touch panel in a displayed key group attribute information storage unit;
- and
- obtaining a link destination attribute and a link destination number in the displayed key group attribute information that corresponds to a first switching key, and outputting the link destination attribute and the link destination number to a display switching unit, in response to a pressing of the first switching key;
- wherein the display switching unit, in response to receiving the link destination attribute and the link destination number from the operation key attribute obtaining unit, reads out from the key group master memory unit, the key group master information designated according to a received link destination attribute and a received link destination number in the displayed key group attribute information that corresponds to the pressed first switching key, and replaces only the second key group with the third key group corresponding to the key group master information designated according to the link destination attribute and the link destination number for display on the touch panel, and updates the displayed key group attribute information by replacing only the key group master information of the second key group with the third key group.
