"Auxiliary Keyboard and Auxiliary Input Device" in Patent Application Approval Process

July 31, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- A patent application by the inventor LIN, CHIA-CHING (TAIPEI CITY, TW), filed on March 8, 2013, was made available online on July 17, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application has not been assigned to a company or institution.

The following quote was obtained by the news editors from the background information supplied by the inventors: "The instant disclosure relates to an input device; more particular, to an auxiliary input device and an auxiliary keyboard each used for a tablet PC.

"With the growing popularity of the tablet PCs, the touch operation of the touch panel is more and more frequently. The tablet PC takes a virtual keyboard to instead of the traditional physical keyboard for saving weight and space.

"However, the virtual keyboard does not achieve the convenient operation of the physical keyboard, because we must rely on the visual to determine the position of the virtual keys of the virtual keyboard, which is limiting the input speed. In contrast, the physical keyboard provides the tactile shape to the user, such that the user does not have to rely on the visual.

"Thus, if the user needs to have a large number of key operations, the user will likely to install an external physical keyboard on the tablet PC. However, the external physical keyboard must be connected to the tablet PC by wire or wireless, such that the external physical keyboard needs to consume the power of the tablet PC. Therefore, the acceptance of the external physical keyboard connected to the tablet PC is only limited to a particular group, and has not been widely accepted by the users.

"To achieve the abovementioned improvement, the inventors strive via industrial experience and academic research to present the instant disclosure, which can provide additional improvement as mentioned above."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventor's summary information for this patent application: "One embodiment of the instant disclosure provides an auxiliary input device and an auxiliary keyboard each capable of the firm connection between the conductive keys and the insulating board.

"The auxiliary keyboard for disposing on a tablet PC, comprising: an insulating board integrally formed includes a sheet having a first surface and an opposite second surface, in which the sheet has a plurality of portions respectively defining a plurality thru holes penetrating the first surface and the second surface; a plurality of resilient supporting portions each having a first end and an opposite second end in which the first end of each resilient supporting portion connects to the sheet, the resilient supporting portions are respectively connected to the portions of the sheet, and a plurality of combined portions respectively connected to the second ends of the resilient supporting portions, in which the thickness of each combined portion is about 0.05 mm to 1 mm; and a plurality of conductive keys of which each key is defined by a bonded portion and an exposed portion. The bonded portions of the conductive keys are respectively and seamlessly coupled to the combined portions, and the exposed portions are arranged to allow exposure from the insulating board. When the second surface of the insulating board is disposed on the tablet PC, each combined portion and a touch panel of the tablet PC are arranged with a predetermined distance therebetween. When pressing at least one of the exposed portions, the resilient supporting portion corresponding to the pressed exposed portion is deformed which causes the combined portion to correspondingly press against the touch panel.

"The instant disclosure also provides an auxiliary input device for disposing on a tablet PC, comprising: an auxiliary keyboard which includes an insulating board integrally formed. The insulating board includes a sheet having a first surface and an opposite second surface, in which the sheet has portions defining a plurality thru holes penetrating the first surface and the second surface; a plurality of resilient supporting portions each having a first end and an opposite second end, in which the first end of each resilient supporting portion connects the sheet, and the resilient supporting portions are respectively connected to the portions of the sheet; a plurality of combined portions respectively connected to the second ends of the resilient supporting portions, in which the thickness of each combined portion is about 0.05 mm to 1 mm; and a plurality of conductive keys of which each key is defined by a bonded portion and an exposed portion, in which the bonded portions of the conductive keys are respectively and seamlessly coupled to the combined portions, and the exposed portions are arranged to allow exposure from the insulating board; and an auxiliary casing having a foldable sheet-like structure. The auxiliary casing has a foldable body, a first connecting portion, and a second connecting portion, in which the first connecting portion and the second connecting portion are respectively connected to the opposite sides of the foldable body. The first connecting portion is fixed on the auxiliary keyboard, the second connecting portion is fixed on the tablet PC while the auxiliary device is adjustable at a desired position or a collapsed position by folding the auxiliary casing. When the second connecting portion of the auxiliary device is fixed on the tablet PC and adjusted at the desired position, the foldable body is used for disposing on a working surface to provide the tablet PC with an acute angle relative to the working surface, the second surface of the insulating board is disposed on the tablet PC, each combined portion and the touch panel of the tablet PC are arranged with a predetermined distance therebetween, and when at least one of the exposed portions is pressed, the resilient supporting portion corresponding to the pressed exposed portion is deformed which causes the combined portion to correspondingly press against the touch panel. When the second connecting portion of the auxiliary device is fixed on the tablet PC and adjusted at the collapsed position, the foldable body, the second connecting portion, and the auxiliary keyboard are collapsibly configured to cover the touch panel of the tablet PC.

"Base on the above, the conductive keys are firmly fixed on the insulating board by the connection between each conductive key and each combined portion. The thickness of each combined portion is about 0.05 mm to 1 mm for enabling a current to pass through each combined portion.
