Abstract
In a wireless keyboard including an antenna wire for radiating a keyboard output signal from a transmitting section into the air and an electrode sheet secured in a keyboard casing and having an electrically conductive pattern coated thereon, the conductive pattern constituting a part of a switch which is turned on by depressing a key, the antenna wire is formed such that an electrically conductive pattern is coated on the electrode sheet in a manner similar to the electrically conductive pattern constituting a part of the switch The antenna wire is formed at the same time as the electrically conductive pattern constituting a part of the switch and integrally with the electrode sheet.
Claims2
A wireless keyboard comprising:
- an antenna wire for radiating a keyboard output signal into the air from a transmitting sections or radiating the keyboard output signal into the air from the transmitting section and receiving a keyboard input signal radiated into the air at a receiving section;
- an insulating electrode sheet having electrically conductive patterns coated thereon, each pattern constituting a part of a switch which is turned on by the depression of each key;
- and
- a keyboard casing,
- wherein the antenna wire is formed of an electrically conductive pattern coated on the electrode sheet.
