Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an information device,
In particular, the present invention relates to a means for a user to improve efficiency through information retrieval, such as document creation, in an information processing apparatus.

[0002]

2. Description of the Related Art In a conventional clipboard management method in an information processing apparatus, a history is indiscriminately stored or stored in a storage area separately prepared manually by a user.

[0003]

In the conventional clipboard management system, it takes a lot of time for the user to find desired data for items stored in the clipboard in the past.

[0004] It is an object of the present invention to provide an environment in which the history of items stored in the past on the clipboard can be clearly specified for each category, thereby improving the efficiency of reuse.

[0005]

In order to achieve the above object, the present invention relates to an information processing apparatus having a clipboard function, comprising a switch for displaying a history for each category, and displaying a history in a desired category. An information processing device having a display unit is provided.

The information processing apparatus has a button for selecting a category on a screen for displaying the history of the clipboard. When this button is selected with a pointing device, a category list is displayed in a list, and when a desired category is further selected, a history corresponding to the selected category is displayed. If all categories are selected here, all histories are displayed.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. In FIG. 1, 101 is an input device, 102 is a display device, 10
3 is a storage device, 104 is a CPU, 105 is an input / output interface (I / O), 106 is a control unit according to the present invention, 107 is a clipboard history display processing unit, and 108 is a clipboard history management processing unit.

The input device 101 is composed of a keyboard and a pointing device such as a mouse or a pen input device, and is used for input such as character input and selection in the clipboard history display processing unit 107 and the clipboard history management processing unit 108. .

The display device 102 is constituted by a CRT or a flat display device or the like, and is used to display the contents processed by the clipboard history display processing unit 107. The storage device 103 includes a memory such as a ROM and a RAM, a hard disk device, and the like, and is used for storing and managing data in each process of the control unit 106. The control unit 106 is realized by program control by a well-known CPU 104 or microprocessor and input / output interface 105.

FIGS. 2 and 3 show display screens according to an embodiment of the present invention.

In FIG. 2, reference numeral 201 denotes an apply button, 202 denotes a close button, 203 denotes a category display area, 204 denotes a category selection list display button, 205 denotes a clipboard history display area, 206 denotes a scroll bar, and 207 denotes an operation input device. (A pointing device such as a pen, hereinafter referred to as a pen)
Represents

An apply button 201 is used to reuse data specified from the clipboard history display area 205. A close button 202 is used to close this screen and shift to a previously displayed screen. The category display area 203 is used to display the category of the history displayed on the clipboard history display area 205. Tapping the category display area 203 with a pen and inputting characters from a known input device adds the category to the category list as a new category.

If the input device is deleted using a known input device, the selected category is deleted. The category selection list display button 204 is used to display a category list for reselecting a category. (The screen shifts to the screen in FIG. 3.) The clipboard history display area 205 is used to display a history that fits the selected category. The scroll bar 206 is used to scroll and check the history when the target history cannot be displayed on the screen.

In FIG. 3, reference numeral 301 denotes a category selection list display area, and 302 denotes a scroll bar.

The item selected from the category selection list display area 301 is adopted as a category, and is used to shift to the clipboard history display screen of FIG. The scroll bar 302 is used for confirming by scrolling that the items to be displayed cannot be displayed in the category selection list display area 301 by scrolling.

FIG. 4 shows a history management method used in the history management processing unit 108 in the configuration diagram (FIG. 1) of one embodiment of the present invention. The history management method 401 is realized by the entire history storage unit 402 and the display data unit 403. The all history storage unit 402 sequentially stores the character string data stored on the clipboard. Display data section 403 stores data relating to the selected category for display.

FIGS. 5 and 6 show flow charts of one embodiment of the present invention. FIG. 5 is a configuration diagram (FIG. 1) according to an embodiment of the present invention.
7 shows a flowchart of the process in 07.

At 501, it is determined whether the number of stored histories does not exceed a previously or dynamically determined maximum number. If not, a new storing process is performed at 502. Further, the storage number is added. If the maximum number is exceeded in 501, old data is discarded in 504, stored data is shifted in 505, and new storage processing is performed in 506.

FIG. 6 shows a flow chart of the display processing in the history display processing unit 107 in the configuration diagram (FIG. 1) of one embodiment of the present invention. At 601, the display buffer is cleared. In 602, it is determined whether the mode is the all history display mode, and if the condition is satisfied, in 603, all data from the all history storage unit is added to the display buffer and the process is terminated.

If it is determined in 601 that the mode is not the all history display mode, the counter is initialized in 604 and it is determined in 605 whether the number of stored history is smaller than the counter. If it is determined to be true in 605, it is determined in 606 whether the data at the counter position from all the history storage units matches the category. Specifically, it is determined whether or not the character string length of the category selected from the head of the stored data at the counter position matches the category. If it is determined in 607 that the category does not match, the counter is incremented in 609 and 6
Return to 05. If it is determined in 607 that it matches the category, 6
At 08, the target storage data is copied to the display buffer. Then, the counter is added at 609 and the process returns to 605.

[0022]

According to the present invention, the user creates a history for each category without newly inputting items which have used the clipboard in the past, thereby increasing the efficiency of data reuse. be able to.
