Coordinate input system and method of controlling same
First Claim
1. A keyboard device comprising:
- a keyboard,key operation detecting means for detecting key operations produced on said keyboard,a coordinate input device arranged near said keyboard and having an operating surface operated by a coordinate indicator,operating state detecting means for detecting an operating state of one of a tap and a slide on said operating surface,screen operating means operative to perform a screen operation in response to information attained from said key operation detecting means and information attained from said operating state detecting means, andcontrol means for inhibiting said screen operation in response to said screen operation operating on said operating screen while said key operation is being detected,wherein said control means includes a processing means operative to initiate inhibiting of processing of said screen operation in response to said key operation being detected by said key operation detecting means and operative to end said inhibiting of said processing after a predetermined time has after said key operation is no longer detected.

Abstract
Disclosed are a coordinate input system and a method of controlling the coordinate input system, which can protect work of a user under progress against troubles even when the user touch an operating surface of a pad by mistake during key input operation on a keyboard. When the user operates a coordinate detecting device (PD) such as a pad, the operating action is sent to a coordinate outputting device (PC) such as a personal computer and analyzed by a data analyzer (12). If the user enters key inputs through a keyboard (19), a controller (15) instructs a mode converter (13) not to inform the operating action detected and sent from the data analyzer (12). After that, the controller (15) clears a timer built in a measuring unit (14) each time an key input is entered. Subsequently, if the key input operation is stopped, the measuring unit (14) actually starts counting of the timer. If the timer value exceeds a certain threshold, this is informed to the controller (15). In response to this notice, the controller (15) instructs the mode converter (13) to resume notice of the operating action detected and sent from the data analyzer (12).

5. A method of controlling a keyboard device comprising at least:
-
a keyboard, key operation detecting means for detecting key operations produced on said keyboard, a coordinate input device arranged near said keyboard and having an operating surface operated by a coordinate indicator, operating state detecting means for detecting an operating state of one of a tap and a slide on said operating surface, screen operating means for performing a screen operation in response to information attained from said key operation detecting means and information attained from said operating state detecting means, and control means operational to inhibit said screen operation in response to said screen operation operating on said operating screen while said key operation is being detected, said method comprising; inhibiting processing of said screen operation when said key operation is detected, resuming said screen operation corresponding to said operating state on said operating surface after determining that an elapsed time after said key operation is no longer detected is greater than a predetermined time.
