Apparatus and method for inputting data
First Claim
1. A data input apparatus with pen means comprising:
- a pen for selectively indicating and inputting desired data;
a display unit for displaying an image of the input data;
a tablet for obtaining coordinate data by indicating with said pen the position corresponding to a predetermined portion of a pattern displayed on said display unit, said tablet being superposed on said display unit in such a manner that the displayed image on said display unit is rendered visible through said tablet;
means for detecting the coordinate data in response to a downward press of said pen to said tablet, and further detecting the coordinate data in response to an upward lift of said pen from said tablet;
means for setting a first region of a predetermined area in said tablet, and also setting a second region which includes said first region and has an area greater than that of said first region; and
deciding means for accepting the input data in response to a downward press of said pen to said first region and thereafter settling said input data in response to an upward lift of said pen from said second region.

Abstract
A data input apparatus comprising a pen for selectively indicating and inputting desired data; a display unit for displaying an image of the input data; a tablet for obtaining coordinate data by indicating with the pen the position corresponding to a predetermined portion of a pattern displayed on the display unit; means for detecting the coordinate data in response to a downward press of the pen to the tablet, and further detecting the coordinate data in response to an upward lift of the pen from the tablet; means for setting a first region of a predetermined area in the tablet, and also setting a second region which includes the first region and has an area greater than that of the first region; and deciding means for accepting the input data in response to a downward press of the pen to the first region and thereafter settling the input data in response to an upward lift of the pen from the second region. The apparatus is capable of preventing unintentional cancel of the input data that may result from an accidental displacement of the pen-up region beyond-the pen-down region, hence facilitating accurate input of data to consequently realize faster manipulation.

6. A method of inputting data by the use of a pen for selectively indicating and inputting desired data, a display unit for displaying an image of the input data, and a tablet for obtaining coordinate data by indicating with said pen the position corresponding to a predetermined portion of a pattern displayed on said display unit, said method comprising the steps of:
-
detecting the coordinate data in response to a downward press of said pen to said tablet; deciding, in accordance with the result of such detection, that the indication signifies a first region corresponding to the position where a desired key is displayed on said display unit; accepting the input data in response to the result of the decision; deciding that said pen has been lifted up from a second region which includes said first region and has an area greater than that of said first region; and settling the input data in accordance with such decision.

7. A data input apparatus with pen means comprising:
-
a pen for selectively indicating and inputting desired data; a display unit for displaying an image of the input data; a tablet for obtaining coordinate data by indicating with said pen the position corresponding to a predetermined portion of a pattern displayed on said display unit; means for detecting the coordinate data in response to a downward press of said pen to said tablet, and further detecting the coordinate data in response to an upward lift of said pen from said tablet; means for setting a first region of a predetermined area in said tablet, and also getting a second region which includes said first region and has an area greater than that of said first region; and deciding means for accepting the input data in response to a downward press of said pen to said first region and thereafter confirming said input data in response to an upward lift of said pen from said second region. - View Dependent Claims (9, 10, 11)
