Abstract

PURPOSE:To execute an input at a high speed by displaying a cursor in the position of an initial value in a row, which is designated by first pushing-down, and moving the cursor by a designated number in the designated direction of a character direction by the pushing down after the second pushing-down and displaying the cursor. CONSTITUTION:When the same switch is continuously pushed down and the A side of the switch is pushed down, a signal (a) is inputted as the count-up clock of an up down counter 8 by a switching circuit 4. When the B side of the switch is pushed down, a signal (b) is inputted as the count-down clock of the up down counter 8 by the switching circuit 4. The up down counter 8 executes the count-up or down of row direction position information according to the (a) or (b) signal and the information are outputted to a control part 9. The control part 9 moves and displays the cursor in the designated position of the same row. Thus, the input can be executed at the high speed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an input device that has a CRT or liquid crystal display means, displays operation items, etc. on the display means, and is operated using a simple instruction circuit.

Conventional technology A conventional method for selecting a desired item from the items displayed on a display section using a simple method is to install switches of the same number as the number of display lines of the display means, in correspondence with the display rows, right next to the display means. A method is used in which it is determined that the corresponding row of the display means is selected by pressing the switch. Further, a method is used in which arrow keys for up, down, left, and right are provided, a cursor is displayed on the display means, and the cursor is moved up, down, left, and right using the arrow keys to make a selection.

Problems to be Solved by the Invention In the conventional method of selecting by using the same number of switches as the number of lines, it is easy to select the line direction, but it is difficult to select the character direction. Although it is possible to provide a switch for the character direction, it is impossible to arbitrarily vary the number of items in the character direction. Furthermore, with the method of setting and selecting the cursor and arrow keys, it is possible to arbitrarily set the number of items in the character direction, but moving the item one item at a time using the arrow keys requires a large number of operations, which is not appropriate.

The present invention has been made in view of the above, and an object of the present invention is to provide an input device that has a simple configuration and requires fewer operations for any number of items in the character direction.

Means for Solving the Problems In the present invention, a momentary type two-contact switch is arranged right next to the display means for the number of display lines, and when the switch is pressed, it A line change detection means detects whether the switch is the same as the switch, and a value predetermined by the change detection signal from the line change detection means is taken as an initial value, and when the same switch is pressed continuously, the two contacts An up/down counter operates with one as a count-up clock and the other as a count-down clock, and receives a line address from the line change detection means and a directional address of the output of the up/down counter, and moves a cursor to a corresponding position on the display means. The input device is equipped with a control means for displaying information.

Effect The present invention has the above-described configuration, and depending on the number of items in the character direction,
When that line is selected, a number corresponding to the position at which the cursor is initially displayed (for example, 3A, which is the number of items in the character direction) is output to the up/down counter by the control means. When a switch different from the previous one is pressed, the change is detected by the line change detection means, and the up/down counter takes in and outputs the specified number from the control means as an initial value. The control means displays a cursor at a corresponding position on the display means using the switch information from the line change detection means as a line address and the information from the up/down counter as a character direction address. If the same switch is pressed continuously, if one contact is pressed, the up/down counter will count up and the cursor display position will be moved forward by one item, and if multiple contacts are pressed, the up/down counter will be counted up. counts down and moves the cursor display position one item back.

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

The figure is a block diagram showing one embodiment of the input device of the present invention. In the figure, 1 is a momentary type two-contact seesaw switch group, 2.3 is an AND circuit group, 4 is a switching circuit, 6.6 is a holding circuit, 7 is a comparison circuit, 8 is an up/down counter, and 9 is a CPU. 10 is an item memory, and 11 is a display section.

First, the control unit 9 reads out the contents of the item memory 1o,
It is displayed together with a cursor on the display unit 11, and the percentage of the number of items in the character direction of the screen is output to the up/down counter as the cursor initial value when a line is selected. When either switch 1 is pressed to select a row, the switch signal is AND
2t-, and is input to the holding circuit 6. At the same time, a holding timing signal is generated by the AND gate 3 and input to the holding circuit 6.6. The holding circuit 6 uses the number of the pressed switch as the row number, and the switching circuit 4, the holding circuit 6. Comparison circuit 7. It is output to the control section 9. Holding circuit 7
The previously selected row number is held in 9, a change in row designation is detected by the comparison circuit 7, and a detection signal is output to the up/down counter 8. The up/down counter 8 takes in the cursor initial value from the control section 9 based on the line change detection signal, and outputs it to the control section 9 as a character direction cursor display position signal. The control section 9 displays a cursor at the corresponding position on the display section 11 based on the row direction signal from the holding circuit 6 and the character direction signal from the up/down counter. At the same time, the switching circuit 4 is switched so that only the signal from the switch pressed by the row number signal passes through.

When the same switch is pressed continuously, if the A side of the switch is pressed, the switching circuit 4 outputs a signal & as a count up clock for the up/down counter 8, and if the B side of the switch is pressed, the switching circuit 4 outputs a signal &. The circuit 4 inputs the signal as a countdown clock to the up/down counter 8. The up/down counter 8 counts up or down the row direction position information in response to the a or b signal, and outputs it to the control section 9. The control unit 9 moves and displays the cursor at a specified position on the same line.

Effects of the Invention As described above, according to the present invention, even on a screen where the number of display items in the character direction changes, when a line is selected, it is possible to display the cursor near the center of the line. Become. In addition, since the selection of the character direction is also used as a line selection switch, there is no need for unnecessary movement of the hand, and high-speed input is possible.
