Abstract

When a jump instruction to display contents regarding a control out of contents in a help screen is given, if the jump instruction is given for a control with the same identification data as that of a control for which a preceding instruction is given, an explanation at a position next to a position of contents displayed in response to the preceding jump instruction is displayed on the help screen, out of the contents of a help data corresponding to the identification data of the control. If the jump instruction is given for a control with different identification from that of the control corresponding to the preceding jump instruction, an explanation at a head position, out of explanations in the help data corresponding to the identification data of the control for which the current jump instruction is given is displayed on the help screen.

Claims

1. An electronic device having a display controller which, in response to a jump instruction to display contents regarding a control out of contents in a help screen, displays, on the help screen, contents corresponding to identification data of the control for which the jump instruction is given, based on help data in which the contents corresponding to the identification data of the control are included at a plurality of dispersed positions, the device comprising: a first help controller which, when the jump instruction is given for a control with same identification data as identification data of a control for which the preceding jump instruction is given, displays, on the help screen, contents at a position subsequent to a position of contents displayed in response to the preceding jump instruction, out of contents corresponding to the identification data of the control; anda second help controller which, when the jump instruction is given for a control with identification data different from the identification data of the control for which the preceding jump instruction is given, displays, on the help screen, contents at a head position, out of contents corresponding to the identification data of the control for which the current jump instruction is given.

2. An electronic device having a help key for accepting an instruction to display a help screen, the device comprising: a display controller which, in response to an operation of another control during an ON operation of the help key, displays, on a display, the help screen including contents corresponding to the operated control;a switch controller which, in response to an OFF operation of the help key performed while no other control is operated during the ON operation of the help key, switches a screen to be displayed on the display between two kinds of screens by a toggle, the two kinds of the screens being the help screen and a regular operation screen other than the help screen;a scroll controller which scrolls the contents of the currently displayed help screen according to an instruction by a user; anda screen content memory which stores data indicating a display state that each of the help screen and the regular operation screen has at an instant when the screen is displayed on the display most recently,wherein, in a screen switching, said switch controller displays, on the display, a selected screen in a same state as the state of the same kind of screen displayed most recently, based on the data stored in said screen content memory.

3. An electronic device according to claim 2, wherein the help key is a hardware key.

4. An electronic device comprising: a loader which is capable of loading help data and a document in a format different from a format of the help data, the help data including position data indicating positions of contents corresponding to identification data of a plurality of controls and format data indicating a display format;a display controller which displays, on a display, contents of data loaded by said loader;a first controller which causes said first display controller to reflect the format data in a display format on the display, only when determining, based on data included in the data loaded by said loader, that the loaded data is help data whose format data is interpretable, and otherwise, causes said display controller to display the contents of the data loaded by said loader as text on the display; anda second controller which, only when determining, based on the data included in the data loaded by said loader, that the loaded data is help data whose format data is interpretable and which is written for a model of the electronic device, permits a jump action in which contents at a position indicated by the position data corresponding to the identification data of an operated control, out of contents in the help data, are displayed on the display according to an operation of the control.

5. An electronic device according to claim 4, wherein each of the position data is described as an anchor tag including the identification data of the control and buried in a position where the contents corresponding to the identification data are described, andwherein in response to the operation of the control, the jump action is executed by displaying, on the display, the contents at the position of the anchor tag including the identification data of the operated control, out of the contents included in the help data.

6. An electronic device according to claim 4, wherein the help data includes the format data as a display tag for formatting the display, further includes a link tag indicating a reference destination, and is described in a markup language, andwherein said first controller causes said display controller to reflect contents of the display tag and the link tag in the display on the display when determining that the display tag and the link tag included in the help data used for the display on the display are interpretable, andthe electronic device further comprisinga second display controller which displays, on the display, data of the reference destination indicated by the link tag, when a portion marked with the link tag in the help data is selected on a screen displayed on the display.

7. An electronic device according to claim 4, further comprising: an interface in which a removable memory is mountable; andan access manager which decides whether or not an operation to the electronic device is to be permitted,wherein said loader loads, from the memory, the help data or the document together with certification data used for certifying a user when the memory is mounted in said interface,wherein said access manager permits only an operation to be permitted to anyone until a certification process using the certification data loaded by said loader succeeds, permits an operation to be permitted to an owner of the certification data when the certification process succeeds, and returns to a state of permitting only the operation to be permitted to anyone when the memory is removed from said interface, andwherein said display controller uses the document loaded by said loader for the display irrespective of the state of said access manager.
