发明名称 Keyboard and apparatus comprising the same
摘要 The present application discloses a keyboard and an apparatus comprising a keyboard. In the keyboard, with the user's habits and ergonomic principles taken into account, the widths of the key rows and/or key columns are made different, so that the keyboard may be miniaturized sufficiently while ensuring its normal operation. To operate the keyboard accurately, separating ribs may be arranged between the keys for preventing the keys from being mis-switched on.
