Abstract

PURPOSE:To improve the operation efficiency and operability by setting the input position of a cursor on a display device and moving the cursor through remote operation. CONSTITUTION:When an input equipment changeover switch 13 selects a remote input device 10, coordinate data set by the remote input device 10 are sent to a cursor information generation part 3. Cursor information outputted by the generation part 3 is processed by a processor 2 and outputted to the display device 1 to set input positions of characters and numerals. For the movement of the cursor by the remote input device 10, a cursor movement signal outputted by the remote input device 10 is sent to a signal reception part 11. A movement signal indicated by the cursor movement signal is converted by a cursor information generation part 3 into cursor information, which is processed by the processor 2, so that the movement of the cursor is displayed on the display device 1. Therefore, the display device can be operated remotely to improve the operation efficiency and operability.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a cursor control device for controlling a cursor displayed on a CRT display device used, for example, for controlling and monitoring industrial plants.

[Conventional technology]

FIG. 2 is a block diagram showing a conventional cursor control device disclosed, for example, in Japanese Patent Publication No. 1-27428. In the figure, 1 is a display device using a CRT or the like, and 8 is an
A tablet provided with coordinates; 9 a segment provided on the tablet 8 indicating the coordinates; 7 an input pen for inputting data by bringing its tip into contact with the segment 9; 6 a scanning control for the tablet 8 and an input pen 7; a tablet control circuit that receives X and Y coordinate data according to the contact area of the tablet;
3 is a cursor information generation unit that generates the coordinate data from the tablet control circuit 6 as cursor information; 2 is a processing device that processes the cursor information from the cursor information generation unit 3; and 5 is a unit that sets the input mode to cursor mode or character mode. A mode key 4 for setting is a switching control section that selectively selects coordinate data from the tablet control circuit 6 as character coordinate data or cursor coordinate data and transmits the selected coordinate data to the cursor information generating section 3. Next, the operation will be explained. When the operator touches the segment 9 on the tablet 8 with the manual ben 7, a ben-on signal is sent to the tablet control circuit 6.
The scanning of the tablet 8 is immediately started upon receiving this Ben-on signal. When a scanning signal is applied to the segment 9 in contact with the input ben 7, this scanning signal is detected by the input ben 7, and the detection signal is sent to the tablet control circuit 6. Based on this detection signal, the tablet control circuit 6 determines whether the input ben 7 is in contact with the
Coordinate data indicating the coordinates is output to the processing device 2 through the cursor information generating section 3. Next, a case where the operator uses the tablet 8 to move the cursor will be described. First, when the input mode is character mode, press the mode key 5 to change the input mode to cursor mode. Next, input Ben 7 into cursor segment 9 of Tablet 8.
When brought into contact with the tablet, the tablet control circuit 6 changes its output state and outputs coordinate data to the cursor information generation section 3 and the switching control section 4. At this time, unless the input mode is switched to the cursor mode in the switching control section 4, the coordinate data is ignored. In the cursor mode, the above coordinate data output to the cursor information generating section 3 is processed by the processing device 2.
A cursor is displayed on the display device 1 at the position indicated by the coordinate data.

[Problem to be solved by the invention]

Since the conventional cursor control device is configured as described above, each time an operator performs an input operation, it is necessary to go in front of the target display device 1 and perform the input operation. There was an issue of becoming more attractive. The present invention was made to solve the above-mentioned problems, and an object of the present invention is to provide a cursor control device that can manually set the position of a cursor on a display device and move the cursor by remote control. .

[Means to solve the problem]

The cursor control device according to the present invention includes a remote input device for inputting coordinate data and a cursor movement signal as an input device, and a switching means for switching between this remote input device and another input device. The cursor displayed on the screen is controlled by remote input.

[Effect]

The cursor control device according to the present invention can display and set a cursor indicating an input position on a display device using a remote input device, and can also move the cursor.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, parts corresponding to those in FIG. 2 are denoted by the same reference numerals, and explanations thereof will be omitted. In FIG. 1, reference numeral 10 denotes a remote input device as an input device for inputting various signals such as coordinate data, cursor movement signals, cursor type selection signals, and numerical signals by remote control;
Reference numeral 11 represents a signal receiving unit that receives the above-mentioned various signals from the remote input device 10, and 12 represents a keyboard as another input device. Further, the input device 7 and tablet 8 are also used as other input devices. Reference numeral 13 denotes an input device switching control unit that selects one of three types of input devices: the remote input device, the input device 7, the tablet 8, and the keyboard 12. In addition, the input device changeover switch I3 and the changeover control section 14
A switching means is constructed. Further, the cursor information generating section 3 and the processing device 2 constitute a signal processing section. Next, the operation will be explained. In FIG. 1, when the input device changeover switch 13 selects the remote human power device IO, coordinate data set by the remote input device IO is sent to the cursor information generating section 3. At this time, the coordinate data obtained by the tablet 8 or the keyboard 12 is ignored by the input device selection information sent from the switching control section 14. Similarly, when the tablet 8 is selected, the remote input device 10 or the keyboard 1
2 will be ignored, and when the keyboard 12 is selected, the coordinate data from the remote input device 10 or tablet 8 will be ignored. Powerful information generation part 3
The cursor information output from the cursor information is processed by the processing device 2 and output to the display device 1, and input positions for characters and numbers are set. When the cursor is moved by the remote human power device 10, a cursor movement signal output from the remote input device 10 is transmitted to the signal receiving section 11.
The amount of movement indicated by this cursor movement signal is converted into cursor information by the cursor information generating section 3 and processed by the processing device 2, after which the movement of the cursor is displayed on the display device 1. Note that the type of cursor to be displayed, for example, a normal cursor or a cross cursor, can be selected from the remote input device 10. Further, inputting one numerical character using the remote input device 10 is performed on the input position set above. In this case, numerical values are input using numerical signals from the remote input device 10, and characters are input by moving the cursor to select from among the alpha characters and syllabary characters displayed on the display device 1. In the above embodiment, a normal cursor or a cross cursor is used as the type of cursor to indicate the coordinate position pointed by the remote input device 10, but a bright spot may be displayed as a cursor on the display device 1. Further, the remote input device may be provided with a screen switching function to switch between a plurality of display devices, and may also be provided with various other functions.
