<p>A scanning type keyboard and keys are provided. The keyboard has a first key area which includes keys, each of which has a connecting mechanism. When a key is pressed down, at least one excitation bus and at least two sense buses are electrically conducted by the connecting mechanism of the key. Thus at least two corresponding sense buses are set to a low level when the key is pressed down. It is enabled to support more keys compared with the way of using one sense bus in the prior art, and increase the number of keys without increasing the General-Purpose I/O (GPIO) ports. The key is enabled to electrically conduct a plurality of buses at a time to meet the requirements for full keyboard input of users, a low cost and a simple and compact structure.</p> |
