BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data communication device for communicating data, and more particularly to a data communication device connected to a data processing device.

[0002]

2. Description of the Related Art Conventionally, a facsimile device has been used as an example of a data communication device.

In recent years, facsimile machines have rapidly penetrated into companies and have established themselves as OA equipment essential for business. At present, functions are expanding and prices are lowering, and a comprehensive lineup from high-end to low-end is being developed. In addition, the transmission speed of MODEM has increased, and is 20 kb.
Those having a transmission rate of ps or more have also been developed. Furthermore, in recent years, the service of the ISDN line, which is a digital communication network, which has been replaced with the conventional telephone line has been started, and G4 facsimiles connecting to the ISDN network are gradually becoming popular.
It is characterized by high resolution of 0 ppi and high speed communication of 64 kbps.

Further, as the use of plain paper for facsimiles has progressed, many facsimiles using laser printers, ink jet printers, etc. have been developed. Due to the high speed communication of G4 or G3 and the high resolution and high speed output of laser printers, the demand for laser facsimiles capable of speedy communication of high quality images has been greatly expanded.

On the other hand, the price of the laser printer itself has become low, and the laser printer has a feature of high quality / quietness and high-speed printing, and is expected to have a position as a standard printing device of a data processing device, for example, a personal computer (hereinafter PC). There is. Most commercially available application software (word processing software, spreadsheet software, etc.) used on a PC has a function of printing data created by the software with a laser printer.

Therefore, there is a demand for a function of printing or transmitting a file of a PC using a facsimile printer. A user can share a copy function, a printer function, and a facsimile function, and can send an image created by a PC as it is, so that a clear image can be sent without being skewed or deteriorated as compared with an image read from a scanner. This is because it is possible, and it is a great advantage in terms of cost and space.

In this case, the conventional facsimile apparatus always accepts the data when the data is sent from the PC.

[0008]

However, since the conventional data communication apparatus always accepts the data sent from the data processing apparatus, the data which should not be recorded may be recorded or should be transmitted. There was a problem that the data that is not sent will be sent.

In order to prevent this, it is conceivable that the data processing device side specifies transmission or recording and sends the data to the data communication device, but this requires new software development and cost reduction. It had the drawback of becoming expensive.

The present invention has been made in view of the above problems, and the present invention accepts data from the data processing apparatus after selecting the type of processing such as transmission processing and recording processing on the data communication apparatus side. An object of the present invention is to provide a data communication device capable of preventing transmission and recording of unnecessary data and transmitting and recording desired data.

A further object of the present invention is to provide a data communication device that does not require special software on the data processing device side because the data processing device does not have to specify the type of processing to the data communication device. And

[0012]

In order to achieve the above object, a data communication device of the present invention is a data communication device connected to a data processing device, and an online mode for receiving data from the data processing device. An offline mode for not accepting data from the data processing device, a switching means for switching between the online mode and the offline mode, a receiving means for receiving data from the data processing device in the online mode, and the reception Output means for outputting the data received by the means, and selection means for selecting the output method of the output means, and the switching means switches from the offline mode to the online mode after the output method is selected by the selection means. , The output means selects the data received by the receiving means by the selecting means. And outputting by the output method.

[0013]

With the above construction, the data communication apparatus of the present invention accepts data from the data processing apparatus in the online mode and does not accept data from the data processing apparatus in the offline mode, and the switching means switches between the online mode and the offline mode. The receiving means receives the data from the data processing device in the online mode, the outputting means outputs the received data, the selecting means selects the output method, and the switching means selects the output method by the selecting means. After that, the offline mode is switched to the online mode, and the output means outputs the received data by the output method selected by the selection means, so that the desired data can be output by the selected output method, and the special software is used by the data processing device.
