The purpose is to [Structure] Two or more cursor actuating tact switches 2A, 2B ... For moving a cursor at different speeds are provided in parallel on the lower surface of one key top 3, and each tact switch 2A, 2B. The operating pressing force for the tact switches 2A, 2B, ... Is made to differ stepwise, and the moving speed of the cursor is variable according to the pressing force.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a switch for cursor keys.

[0002]

[Prior art]

 As a method of moving the cursor on the display screen of the CRT or LCD, there are a joystick method, a trackball method, and the like. As shown in FIG. 5, two pairs each corresponding to vertical and horizontal movement of the screen and horizontal and horizontal movement are combined. In many cases, a switch key method in which four cursor keys A to D are arranged on the keyboard F is used. By the way, with the switch key method, when you want to move the cursor on the display screen significantly, the processing time is too long at normal moving speed.Therefore, move the cursor depending on the length of time the cursor key is pressed or the number of times it is pressed. Speeding up is done.

[0003]

[Problems of conventional technology]

 However, in the case of the above method, the cursor moving speed on the display screen can be increased but cannot be gradually decreased, and it can only be stopped, so it is difficult to stop moving the cursor to the target position. There was a problem that it required skill to operate.

[0004]

[Problems to be solved by the device]

 In view of the above problems, the present invention has been made for the purpose of facilitating the position adjustment of the cursor on the display screen by making it possible to adjust the moving speed of the cursor to either high or low speed according to the pressing force of the key. It is a thing.

[0005]

[Means for Solving the Problems]

 That is, the cursor key switch of the present invention is provided with two or more cursor actuating tact switches 2A, 2B ... For moving the cursor at different speeds in parallel on the lower surface of one key top 3, and the key is the key. The operating pressure on the tact switches 2A, 2B ... Of the top 3 is made to differ stepwise for each tact switch 2A, 2B.

[0006]

[Action]

 In this invention, one key top 3 for moving the cursor is provided with two or more tact switches 2A, 2B ... Which move the cursor at different speeds, and when one tact switch 2A is turned on. , The cursor movement speed when the other tact switches 2B ... Are turned on is made different, and the operation pressing force of each tact switch 2A, 2B ... of the key top 3 is made different step by step for each tact switch. Therefore, by increasing or decreasing the pressing force of the key top 3, the cursor moving speed on the display screen can be arbitrarily adjusted.

[0007]

【Example】

 Next, an embodiment of this invention will be described. 1 is a sectional view of a cursor key switch according to an embodiment of the present invention, FIG. 2 is a front view showing a substrate of a tact switch, FIG. 3 is a sectional view of another embodiment, and FIG. 4 is a sectional view of yet another embodiment. It is a figure.

Embodiment 1 As shown in FIG. 2, two tact switches 2A and 2B are arranged on a substrate 1 in correspondence with a key top 3 on which an arrow indicating the moving direction of a cursor on a display screen is displayed. As shown in FIG. 1, a step h is provided on the back surface of the rubber key top 3, and when the pressing force of the key top 3 is weak, only one tact switch 2A is turned on by the protruding step 3A side, When the pressure is strong, both the tact switches 2A and 2B are configured to be turned on by the protruding step 3A and the concave step 3B. The moving speed of the cursor depends on whether the tact switch 2A alone or both 2A and 2B. I made it change. In this case, if the pressing force is increased, the moving speed of the cursor becomes faster, and if the pressing force is weakened, the moving speed of the cursor becomes slower, and the moving speed could be adjusted without stopping the cursor one by one. .

Example 2 Three tact switches 2A, 2B, and 2C are arranged on the substrate 1 so as to correspond to a keytop 3 on which an arrow indicating the moving direction of the cursor on the display screen is displayed, and rubber is used. As shown in FIG. 3, a step h that changes in three steps is provided on the back surface of the key top 3 made of metal, and the steps 3A to 3C are sequentially contacted according to the pressing force of the key top 3. When the cursor movement speed was changed so as to be changed depending on the ON state of the tact switches 2A to 3C, the movement speed could be adjusted more delicately than in the first embodiment.

Example 3 As shown in FIG. 4, the same procedure as in Example 1 was carried out except that the back surface of the rubber key top 3 was made a flat surface and the operating pressures of the tact switches 2 A and 2 B were changed. It was possible to adjust the height of the moving speed as in Example 1.

[0011]

[Effect of device]

 As described above, this device has two or more tact switches with different corresponding speeds provided on the bottom surface of one key top, and these can be selectively connected according to the pressing force. You can either accelerate or decelerate, and it will be very easy to move the cursor.
