Description

1226568 V. Description of the invention (1) The technical field to which the invention belongs The present invention relates to a keyboard with a corner and an operation degree. Prior art Fig. 1A and Fig. 1B are side views, as shown in Fig. 1A. In order to conform to the ergonomics, each key 12 can be set with a tilt angle that is too small. The support rod 1 3 (Figure 1B) is tilted to match the operating angle of the traditional keyboard 1 1 The operating angle 13 of the keyboard 11 is adjusted by the depression of the bottom surface of the keyboard 11 of the conventional keyboard 11. SUMMARY OF THE INVENTION In view of this, this offer 'allows the user to operate the keyboard very much, and improves the key type of keyboard, and particularly relates to an adjustable operation, which is shown in the conventional keyboard, the traditional keyboard 1 1 learns, the traditional keyboard 1 1 has Appropriate operation is "user-adjustable" so that the rods 13 are backward to the needs of the user. It can only be used as in Section 1B. In addition to the preset adjustable position, it is also necessary to pull out the keyway and rotate it in a manner that is less suitable for humans. There are a plurality of keys with a preset tilt angle in different operating states. However, when the keyboard π is preset to protrude in front of the bottom of the keyboard 11 and the angle of changing the support rod 13 shown in the keyboard 11 is limited, the dial 11 is lifted up and then the support rod is turned to the preset position. Because of the engineering, it must be clear that the purpose of improvement is to simply and quickly change the convenience in the operation of the disc. Another object of the present invention is to provide the needs of a person. The present invention provides an improved elevation angle of the keyboard or keyboard. Keys with multiple operating elevation angles can be adjusted in a sliding manner to suit different uses To achieve the above purpose
