Keyboard arrangement |
摘要 |
In order to diminish the physical troubles often occurring with the usual keyboard arrangement, the alphanumeric keyboard is subdivided into two keyfields mounted on a support having a wedge-shaped extension towards the operator which extension is used as an arm rest. The keyfields are located in planes rising from the operator side of the keyboard which planes slope downward from the middle to the outside. In addition the keyfields enclose an angle open towards the operator in order to diminish the flexion of the hand with respect to the forearm needed with the prior one-piece keyboard. On both sides of these two keyfields two further keyfields are provided for numerical keys and/or function keys, for instance for data input devices. The additional keyfields are located in planes rising from the operator side of the keyboard without sloping to the outside.
