Abstract

A retrieval and display device includes an ascending-direction reading out section and an descending-direction reading out section, which read outs a folder name from a folder-name storing section, in response to an operating-direction signal from a storing and operation direction discriminating section and a display-linage signal stored in a display-linage section; and a mark-position changing section, which changes the position of a mark according to whether an operation is done in the ascending direction or in the descending direction. A display folder-name creation processing section places the mark on a folder name desired to be selected in the top line at the operating direction, and creates a display folder name such that the next candidate folder is displayed in the display screen.

Claims

1. A retrieval and display device comprising:

a display section having a display screen able to display at least two or more lines of a folder name;

a folder-name storing section storing enormous numbers of folder names;

a display-linage storing section storing the number of display lines of the display section;

an operating section generating an operating signal for indicating a direction in which the folder name is read out;

a storing and operating direction discriminating section, when receiving the operating signal from the operating section, discriminates the operating direction in comparison with the operating direction stored therein;

a downward-direction reading out section and an upward-direction reading out section reading out a folder name from the folder-name storing section, in response to an operating-direction signal from the storing and operating direction discriminating section and a display-linage signal stored in the display-linage storing section;

a mark-position changing section changing a position at which a mark output from a mark-generating section is displayed, in response to the operating direction signal from the storing and operating direction discriminating section; and

a display folder-name creation processing section receiving folder names corresponding to the number of display lines from the downward-direction reading out section or the upward-direction reading out section, receiving a mark-position changing signal from the mark-position changing section, putting the mark on a desired folder name, and displaying the desired folder name on which the mark is put, on the display section, wherein

the mark-position changing section changes a position at which the mark is displayed, from the top line to the bottom line or from the bottom line to the top line in the two or more display lines of the display section, in response to a changing signal for indicating that the operating direction is changed between an downward-direction and an upward-direction, from the storing and operating direction discriminating section, and

the mark-position changing section changes the position at which the mark is displayed, from the top line to the bottom line in response to the changing signal for indicating that the operating direction is changed from the downward-direction to the upward-direction, and from the bottom line to the top line in response to the changing signal for indicating that the operating direction is changed from the upward-direction to the downward-direction.

2. The retrieval and display device according to claim 1, further comprising a timer starting up by the operating-direction signal, wherein an instruction to the downward-direction reading out section and the upward-direction reading out section is stopped for the period of time preset by the timer, the display folder-name creation processing section displays the folder names without changing the folder names, only by changing a position at which the mark is displayed, from the top line to the bottom line or from the bottom line to the top line in the two or more display lines of the display section according to the mark-position changing signal from the mark-position changing section.
