Description

[Detailed Description of the Invention] [Summary] A composite communication terminal device with a structure that integrates a display and a handwritten information input device is used to input document information in code format.
This allows handwritten information such as an approval signature to be easily added and transmitted.

[Industrial application field]

The present invention relates to a composite communication terminal device capable of displaying and handwriting input used in e-mail systems and the like, and particularly to a composite communication terminal device for inputting handwritten information in addition to document information displayed on a display.

[Conventional technology]

Recently, in addition to the widespread use of personal computers, word processors, and facsimile machines, offices have begun to implement single-internal mail systems through the introduction of complex PBXs and LANs.

By the way, in a conventional in-house mail system, document information using a one-character code and image information in a bitmap format are input/output and transmitted using separate terminal devices.

For example, in a system where a document is sent to an administrator via two internal mail systems, the administrator signs the document for approval, and then forwards it to the sender or another workstation. The administrator can either sign the document with a pen, input it again into the facsimile machine, and transfer it, or output the two documents on a display screen, look at them, and sign using another drawing input device such as a tablet. Enter by hand.

A method has been adopted in which this composite screen information is transferred in bitmap format.

[Problem that the invention seeks to solve]

In conventional e-mail systems, it is not possible to input and output character information in code format and image information in bitmap format using a single terminal device. It is necessary to transfer data in a bitmap format, which is inconvenient to operate, takes a long time to transfer, and is inefficient.

[Means for solving problems]

FIG. 1 shows the general configuration of a composite communication terminal device according to the present invention.

In FIG. 1, for example, document information in code format transferred from an e-mail system to a multifunction communication terminal device l via a line 9 is identified as document information by a communication control unit 8 and stored in a document buffer 6. be done.

The display control unit 7 reads out the document information in the 9-document buffer 6, converts the character code into a character pattern, and displays it at a designated screen position on the display 2.

On the other hand, the 2 handwritten information input means are 9, for example, a transparent tablet 3
．． It consists of an input pen 3a and a coordinate position detection section 4, and input handwritten information is stored in an image buffer 5.

The communication control unit 8 sequentially sends the document information in the one-document buffer 6 and the handwritten information in the image buffer 5 to the communication line 9.

[Effect]

With the above configuration, the transparent tablet 3 is attached so as to be in contact with the display screen of the display 2, and it is possible to clearly read the information output and displayed on the display 2 through the transparent tablet 3. . The user (administrator) reads the document information output and displayed on the display 2.

In response, the pen 3a is used to handwrite information such as a signature in a predetermined area of the transparent tablet 3.

The coordinate detection unit 4 detects each coordinate position of the trace of handwritten information written on the tablet 3 using the pen 3a, and stores it in the image buffer 5. The handwritten information stored in the image buffer 5 can be displayed on the display 2 by the 1 display control section 7.

The communication control unit 8 stores one document buffer 6 according to the user's instructions.
The document information in the image buffer 5 is sent out in code format, and then the handwritten information in the image buffer 5 is sent out in bitmap format.

These pieces of information sent out from the multifunction communication terminal device 1 are transferred through nine lines 9 to, for example, an e-mail system.

In this way, a composite communication terminal device is provided in which a function for outputting and displaying character information in a code format and a function for inputting handwritten information in a bitmap format are integrally connected.

By using this as a terminal for an e-mail system, it is possible to efficiently perform response processing such as approval signatures for two documents.

〔Example〕

The details of the present invention will be explained below based on examples.

FIG. 2 is a block diagram of a device according to one embodiment of the present invention, and shows the case where it is used in an approval signature system. In the figure, 10.11 is a composite communication terminal device, 12 is a digital PBX, 13 is an information storage module, 14 is a display, 14a is a document display area, 14b is an approval sign display area, 15 is a transparent tablet left, and 16 is a coordinate detection unit. , 17 is an address conversion section, 18 is a bitmap format image buffer, 19 is a code format document buffer, 20 is a display control section, 21 is a display area control section, 22 is a transmission section, and 23 is a reception section.

The composite communication terminal device 10.11 and the information storage module 13 can be connected to each other via the digital PBX 12.

The information storage module 13 is, for example, an e-mail system, and manages the transferred mail document information in a file for each mail destination so that it can be retrieved upon request.

The display 14 and the transparent tablet J5 are integrally formed as described above. It is preferable that the display 14 be of a flat type, and that the transparent tablet left be of a capacitive coupling type using a transparent resistive film. In addition, when using the transparent tablet 15 only for filling in the approval signature,
The transparent tablet 15 may be relatively small in size commensurate with the size of the approval sign display area 14b of the display 14.

The x and y coordinates of handwritten information such as an approval signature input from the transparent tablet 15 are detected by the coordinate detection section 16 and applied to the address conversion section 17 and the transmission section 22 .

Each x and y coordinate of the input handwritten information is converted into a bit address of the image buffer 18 in the address conversion section 17 and written into the image buffer 18.

The handwritten information written in the image buffer 18 is displayed on the display 14 according to instructions from the 1 display area control section 21.
It is read out at the display timing of the approval sign area 14b of the display 14 and displayed on the approval sign display area 14b of the display 14 by the display control section 20.

On the other hand, the code-format document information stored in the 2-document buffer 19 is read out at the display timing of the document display area 14a of the display 14 according to instructions from the 9-display area controller 21, and is read out at the display timing of the document display area 14a of the display 14 by the 9-display controller 20.
4a.

The transmitting unit 22 transmits the coordinates of the coordinate detecting unit 1 when a transmission instruction is given.
The coordinate output of 6, the bitmap format data of the image buffer 18, or the code format data of the document buffer 19 are assembled into a predetermined frame and sent to the digital PBX 1.
2 to the destination.

Further, the receiving unit 23 stores information received in the same frame format in the one-document buffer 19 or the image buffer 18 depending on whether the information is in a code format or a bitmap format.

FIG. 3 shows an HDLC frame as an example of the information transfer format, where F is a frame synchronization flag, A is an address field, and C is a control field. M is a media parameter that indicates whether the data is a code, bitmap, or coordinate. Also, DATA is an information field.

CRC is a cyclic redundancy code for frame checking.

When this HDLC frame is used in the embodiment shown in FIG.
A transmitter 22 sets the media parameters of the frame at the time of transmission, and a receiver 23 decodes the media parameters of the frame at the time of reception and allocates information to be stored in an image buffer 18 or a document buffer 19.

By using a multifunction communication terminal having the above configuration, it becomes possible to electronically sign an approval signature on a received document and easily send it back.

〔Effect of the invention〕

According to the present invention, terminal operation is facilitated, document information is transferred in code format, and handwritten information such as approval signatures is transferred in bitmap format, thereby increasing transfer efficiency and further reducing the cost required for the terminal. can.
