`
`ABSTRACT
`
`When a user touches a tablet with a pen, a coordinate pointed
`with a nib of a pen and a tool force on this coordinate are
`detected, and a cursor is displayed at a position correspond(cid:173)
`ing to the coordinate in a display device. Furthermore, the
`shape, color and size, etc., of the cursor can be varied
`according to a change in coordinate, tool force. This permits
`the user to recognize a level of the tool force which he
`actually applies at a glance. Additionally, an operational
`mode is switched according to an amount of change in
`detected coordinate and the tool force. As a result, the user
`is permitted to control an operational mode of the document
`processing device with ease only by a pen operation, thereby
`improving an operability.

`DOCUMENT PROCESSING DEVICE
`
`FIELD OF THE INVENTION
`
`The present invention relates to a document processing
`device such as a Japanese word processor, an alphanumeric
`word processor, a DTP (Desk Top Publishing) devise, a
`personal computer, etc., more particularly relates to a docu(cid:173)
`ment processing device which permits a document or an
`image to be inputted or edited using a pen input interface
`that can detects a tool force.
`
`BACKGROUND OF THE INVENTION
`
`5
`
`10
`
`2
`Besides, according to the described arrangement, when
`the user does not wish to vary the width of the line, etc.,
`according to the level of the tool force, it is required to
`switch an operable mode between a mode in which a tool
`force is detected and a mode in which a tool force is not
`detected. To perform such switching of the operational
`mode, a troublesome operation is required, such as removing
`a pen from the current position to select a menu or an icon,
`etc. Moreover, Japanese Laid-Open Patent Application No.
`195938/1983 (Tokukaisho 58-195938) fails to disclose
`operation means for locking the expansion in a desired
`enlarged scale. Such operation means is obtainable with
`ease, for example, by forming a lock instruction key on the
`keyboard, or forming a switch attached to a pen, etc. In the
`15 former case; however, it is required to operate a key on the
`keyboard with a hand which does not hold a pen as the other
`hand is occupied with the pen, thereby presenting a draw(cid:173)
`back of low operability. On the other hand, when adopting
`the latter case, a cost of manufacturing the device would be
`20 increased.
`Additionally, there are known editing technique based on
`borders such as an image border, a graphic border, a char(cid:173)
`acter border, etc. However, the technique of scaling such
`borders as a whole has not yet been proposed. For example,
`25 although Japanese Laid-Open Patent Application No.
`119415/1991 (Tokukaisho 3-119415) teaches the arrange(cid:173)
`ment for scaling graphics, the technique adopted therein is
`not based on borders.
`
`Recently, using word processors, personal computers,
`etc., plotting/editing of characters, images, etc., are permit(cid:173)
`ted using a pen input interface such as a stylus pen, a tablet,
`etc., with simple and easy operation by means of a pen.
`However, most pen input interfaces available on the market
`do not have a tool force detecting function, and the effective
`use of the tool force detecting function has not yet been
`spread.
`There are known techniques of varying a width of a line
`or a size of a dot for plotting based on a level of a tool force,
`and techniques of selecting an object to be edited based on
`a level of a tool force, etc. With the conventional techniques,
`the tool force is in proportion to the width of a line for
`plotting, and a plotting can be performed using a line of a
`variable width by adjusting a tool force.
`Such conventional techniques are known, for example,
`from Japanese Laid-Open Patent Application No. 279980/
`1992 (Tokukaihei 4-279980) wherein a plurality of different
`An object of the present invention is to provide a docu(cid:173)
`objects or windows are selected based on a level of tool
`ment processing device wherein characters, graphics, etc.,
`force detected by a tool force detecting device. In the device
`are inputted by a user by means of a pen, which permits a
`of this citation, an image is plotted by controlling a trans-
`control of various types of operations only by adjusting a
`missivity to color used in plotting based on a level of a tool
`tool force applied by the user.
`force, a mixed ratio of a color used in a background to a
`To fulfill the above object, the document processing
`color used in plotting an image is adjusted to form a natural
`apparatus in accordance with the present invention is char(cid:173)
`image like a recoating in a watercolor painting.
`acterized by including:
`Another technique is disclosed in Japanese Laid-Open 40
`pointing means for allowing a user to specify a coordinate
`Patent Application No. 282094/1993 (Tokukaihei
`by applying thereon a tool force;
`5-282094), wherein a handwritten input can be made as if
`coordinate detection means for detecting a coordinate

`pointing means for allowing a user to specify a coordinate
`by applying thereon a tool force;
`coordinate detection means for detecting a coordinate
`specified by the pointing means;
`tool force detection means for detecting a tool force at a 5
`time the coordinate is specified;
`display means; and
`plotting means for plotting an image in the display means
`at a position corresponding to a coordinate detected by
`the coordinate detection means,
`wherein an operational mode of the plotting means is
`switchable between a variable mode in which a plotting
`process is performed according to a tool force detected
`by the tool force detection means and a fixed mode in
`which a plotting process is performed according to a
`predetermined constant tool force, and the operational
`mode of the plotting means is switched between the
`variable mode and the fixed mode based on a change in
`at least one of the coordinate detected by the coordinate
`detection means and the tool force detected by the tool
`force detection means.
`According to the described arrangement, an operational
`mode of the document processing device can be switched
`only by adjusting an amount of movement of the specifying
`means and a current level of the tool force. Therefore, the
`described feature permits the user to adjust the tool force
`while plotting characters, graphics, etc., by utilizing the
`specifying means which actually serves like a real pen,
`thereby improving an operability of the document process-
`ing device.
`To fulfill the aforementioned object, a still another docu(cid:173)
`ment processing apparatus in accordance with the present
`invention is characterized by including:
`pointing means for allowing a user to specify a coordinate 35
`by applying thereon a tool force;
`coordinate detection means for detecting a coordinate
`specified by the pointing means;
`tool force detection means for detecting a tool force at a
`time the coordinate is specified;
`display means; and
`graphic border control means for scaling a graphic border
`in the display means in accordance with a change in
`tool force when a coordinate detected by the coordinate
`detection means is on the graphic border.
`The described arrangement permits a scaling of the
`graphic border with a simple operation of only adjusting a
`tool force while specifying the graphic border, thereby
`achieving an improved operability.
`The novel features which are considered as characteristic 50
`of the invention are set forth in particular in the appended
`claims. The improved treatment method, as well as the
`construction and mode of operation of the improved treat(cid:173)
`ment apparatus, will, however, be best understood upon
`perusal of the following detailed description of certain 55
`specific embodiments when read in conjunction with the
`accompanying drawings.
