An icon (image display) showing the contents of the image is displayed. Next, the operation numbers in such a configuration will be explained. For example, in a state where an icon is currently being displayed, the operator moves the cursor C using the position designation keys 11a1, . . . . Then, when the cursor C corresponds to the position of the desired icon, the selection key 12 is pressed. Then, CPU13
outputs a selection signal to the main control section 1. Thereby, the main control unit 1 determines the content of the icon corresponding to the position of the cursor C, and performs processing according to the content. That is, when the operator selects an icon indicating deletion while icons corresponding to function keys are displayed on the CRT display device 3 as shown in FIG. Then, the display contents on the CRT display device 3 are changed to that shown in FIG. In response to this display, when the operator selects an icon indicating a desired image, the main control unit 1 displays the corresponding image. Next, the operator uses the position designation keys 11a, . Furthermore, the operator presses the selection key 12 twice in succession. Then, when the selection key 12 is pressed for the first time, the CPU 13 outputs a start signal to the timer 14 and lights up the selection key 12. Then, the timer 14
A timing signal is output to B. In this case, while the timing signal is being supplied, a signal from the selection key 12 is again supplied to the CPU 13, and the CPU 13 retains the hold selection function and outputs a signal corresponding to that mode to the main control section 1. Then, the main control unit 1 determines that the position currently indicated by the cursor C is one diagonal position in the deletion range.The operator then deletes the cursor C using the position designation key 11a1... Set it at the other diagonal position point B of the range to be performed.Furthermore, the operator presses the selection key 12.Then,
The CPU 13 outputs a selection signal to the main control section l. Then, the main control unit 1 determines that the position currently indicated by the cursor C is the other diagonal position in the deletion range, and deletes the range defined by this diagonal position and the above-mentioned one diagonal position. It is determined that the area is within the range, and the deleted portion of the image is deleted from the image currently displayed on the CRT display device 3 and displayed as shown in FIG. In this way, pointing using a pointing device such as a mouse can be easily performed using a keyboard without requiring an operation space. As a result,
Not only can it be made smaller, but it can also be made cheaper. In addition, since the position is specified using a position specifying key, it is easy to move in a straight line, and unlike a mouse that moves mechanically, it is less likely to malfunction. Additionally, in the past, when attempting to perform a specific operation using a keyboard, you had to keep the select key pressed and move the cursor using the movement keys; however, the selection key retains the selection function. , because only the movement keys are required, instructions can be easily given. In the above embodiment, the selection key has been described as having a holding function, but the present invention is not limited to this, and the selection key may be arranged so as to be operated with the hand opposite to the position designation key.
