Abstract

PURPOSE:To attain the setting of a coordinate detection/transfer mode at each range where a coordinate detection section exists by allowing a detection coordinate discriminating section to section a detected coordinate string from a coordinate detecting section according to the content of a storage section and giving/ receiving it to a transfer control section. CONSTITUTION:The coordinate string indicated by a coordinate indicating section 1 is arranged only to an effective coordinate string effective to the coordinate detecting section 2. The coordinate string is transferred as it is to a detection coordinate discriminating section 3. The discriminating section 3 reads discriminating information stored in a storage section 4, compares the discrimination information with a coordinate, decides the form of transfer as to the effective discriminating information, adds the transfer mode as the discriminator and transmits the coordinate string to a transfer control signal section 5. Then the control section 5 processes the coordinate string transferred from the discriminating section 3 according to the discriminator transmitted similarly, converts it into a prescribed transfer mode format and transfers it to other device through a signal line (f).

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Description of the field to which the invention pertains The present invention relates to a coordinate transfer device, particularly a coordinate transfer device, a magnetic field beso pure ＾ hat obi 壬 dan F? This invention relates to a W1 standard transfer device that detects the coordinate values of the 9,000-year-old 9,000-year-old man and sends them to other devices.

(2) Description of conventional technology Conventionally, this type of device has a coordinate indicating section and a coordinate detecting section.

It consists of a detected coordinate transfer control unit, etc., and detects and transfers modes (e.g., a mode that transfers detected coordinate values at fixed time intervals, a mode that transfers only the first detected coordinate value, a mode that transfers only the first detected coordinate value, and a mode that transfers detected coordinate values when the detected coordinate value changes). There is a mode in which the data is transferred only when the coordinate detection unit is used. For this reason, it is not possible to simultaneously perform multiple modes such as detecting and transmitting coordinates at fixed time intervals for the range covered by the coordinate detection unit, and transmitting only the first detected coordinates for a certain range. Furthermore, it has been virtually impossible to arbitrarily specify the range of detection/transfer modes.

(3) Purpose of the Invention The purpose of the present invention is to solve the above-mentioned problems by making it possible to set a coordinate detection-transfer mode for each range of the coordinate detection unit. do.

(4) Description of structure and operation of the invention FIG. 1 shows an embodiment of the present invention, in which 1 is a coordinate indicating section, 2 is a coordinate detecting section, and 6 is a detected coordinate identifying section.

4 is a storage section, and 5 is a transfer control section. Also, ■ is the instruction part 1
This is a signal line for transmitting the signal picked up by the sensor to the detection unit 2.
■ is a signal line that notifies the detection unit 2 that the indicating means (magnetic pen, light pen, etc.) has contacted the indication unit 1, and ■ is a signal line that transmits the coordinate value string detected by the detection unit 2 to the identification unit. 2 is a signal line for transferring information necessary for the operation of the identification section 3 from the storage section 475.

■ is a signal line that is used to transfer information processed by the identification unit to the transfer control unit 5, and ■ is a signal line that is used to transfer information from this device to other devices such as the main unit, or vice versa. (2) is a signal line for transmitting identification information stored in the storage unit (described later, see FIG. 2) transferred from another device via the signal line (2) or the transfer control unit 5.

Next, the operation of this device will be explained step by step. Coordinate instruction section 1
The coordinate value sequence designated by is adjusted to only a valid coordinate value sequence by the detecting unit 2 depending on the presence or absence of a signal from ■ (for example, a signal is guaranteed to be present at the time of contact).

This coordinate value string is transferred as is to the identification section 3 through ■. The identification unit 3 uses the identification information (
(described later), compares the identification information with the coordinate values, determines the transfer form for valid identification information, adds the transfer mode as an identifier, and transfers the coordinate value string to the transfer control unit 5.
send to The identifier may be sent by adding it to the coordinate value string.

It may be sent separately from the coordinate value string. Next, the transfer control section 5 processes the coordinate value string transferred from the identification section 3 according to the identifier also sent, converts it into a predetermined transfer mode format, and transfers it to another device via the signal line (2).

Next, when information for changing the transfer mode range is received from another device via the signal line (2) or the transfer control unit 5.

The information is stored in the storage unit 4 via the signal line and the identification information is changed. The identification unit 6 always reads the storage unit 4 when operating.
Since the identification information stored in the transfer mode is checked, if the transfer mode designation or range designation changes, corresponding processing will be automatically performed. With this configuration, the transfer mode and range can be easily changed by simply changing the contents stored in the izu storage unit 4.
In addition, it can be changed at any time from another device, and there is no limit to the range or number of transfer modes, allowing detailed specification, and there is no limit to the number of times the transfer mode can be changed, so it can be changed dynamically.

The 21st prisoner indicates identification information stored in the storage unit 4 in this embodiment, and FIG. 2 (shows the operation flow of the BI U identification unit B). A transfer mode is given to determine in what form the coordinate value of is sent to the other device u.In the figure, the
This shows the case of range specification using coordinates. Instead of XY coordinates, polar coordinates or the like may be used. The operation flow of the identification unit B is based on the recognition of the detected coordinate values. After being identified here, the identifier is entered and transferred to the transfer control unit 5.

FIG. 3 is a diagram for explaining how the transfer control unit 5 processes the coordinate string according to the identifier added by the identification unit 3 and converts it into a format determined by the transfer mode. In the figure, in a state where a detected coordinate value string is given, transfer mode 1 (a mode in which only the first detected coordinate value is transferred) is selected based on the identification information as shown in FIG.

□In transfer mode 2 (a mode that transfers the first detected coordinate value and last detected coordinate value) and transfer mode 6 (a mode that transfers all detected coordinate values as is), the identification unit 3
This shows how the coordinate value string sent from (in the figure, the detected coordinate value string) is processed.

In the figure, 6 is a format of an example of a detected coordinate value sequence, 7 is a transfer format corresponding to transfer mode 1, 8 is a transfer format corresponding to transfer mode 2, and 9 is a transfer format corresponding to transfer mode 3. It represents. The operation of the detected coordinate identification section 6 and the operation of the transfer control section 5 shown in FIG. 1 will be described below.

For example, if "coordinate 1" corresponds to diagram format 6 in Figure 3,
”, “coordinate 5” and “coordinate 6” are range 1 of the second inversion
It is in the coordinate range belonging to ``coordinate 2'', ``coordinate 6'', and ``coordinate 6''.
"Coordinate 4" is included in the coordinate range belonging to range 2 shown in the second rotation diagram, and further K "coordinate 7" and subsequent parts are in the coordinate range belonging to range 2 shown in the second illustration (range 3 shown in A1).
Suppose that it is in the coordinate range belonging to . In this case, the detected coordinate identification section 6.

First, it is determined that "coordinate 1" is within "range 1" and "transfer mode 1" is known. Then, "coordinate 1" is transferred to the transfer control unit 5 with an identifier corresponding to the transfer mode IJK attached. Similarly, "coordinates 2".

"Coordinate 6", ... "Coordinate 7", ...
The transfer control unit 5 asks for identifiers for each
will be transferred to.

The transfer control unit 5 receives this and (11r coordinate 1
” in the illustrated format 7 in Figure 3 + fill “
Format 8 in the third diagram for "coordinates 2" to "coordinates 4," format 7 for "coordinates 5" and "coordinate 6," and format 9 for "coordinates 7" and beyond. Each signal should be sent on the signal line ■.

(5) Description of Effects As explained above, according to the present invention, transfer modes and ranges can be specified in detail, and can be specified at any time and any number of times. Therefore, a plurality of coordinate detection devices, which conventionally had to be provided for each of the nine functions, can be reduced to just one water device, making it possible to achieve great economical efficiency. Furthermore, since any range of coordinates can be specified to any transfer mode, it is possible to use one range as a normal digitizer and another range as various switches (space division usage), or in some cases coordinate Digitize the whole thing.

It is possible to use the entire panel as a 7 alexion switch panel (time-divided usage) when the system is in use. In addition, if the coordinate indicating part is a transparent part and the lower part is a display part such as EL or liquid crystal, a device having both display and touch input, that is, input and output, is constructed. By changing the display button and coordinate detection/transfer mode as appropriate,
It becomes possible to realize highly intelligent input/output devices with a wide variety of types and excellent operability.
