Abstract

PURPOSE:To improve an executionability and a workability by transmitting a picture signal read out at a slave equipment side to a master equipment side by a radio signal, and transmitting the picture signal obtained to receive and demodulate the transmitted radio signal at the master equipment side. CONSTITUTION:This is constituted to combine a master equipment 1 and plural slave equipments 2. Here, the picture signal read out in a picture reading part 24 of the slave equipment 2 side is transmitted to the master equipment 1 side by the radio signal, and at the master equipment l side, the picture signal obtained to receive and demodulate the transmitted radio signal is transmitted to a telephone line (l), and a facsimile transmission is executed. Thus, since the data transmission and reception is executed between the facsimile slave equipment 2 and the facsimile master equipment 1 by the radio signal, the executionability and the workability can be improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wireless facsimile transmission/reception system, and more specifically, to a system for transmitting wireless signals between a centrally installed facsimile main unit and a facsimile slave unit. The feature is that the facsimiles can be sent and received by each handset by mutual transmission.

[Prior Art] Recently, facsimile transmitting/receiving devices (hereinafter referred to as facsimiles) have come into use, and companies generally have one or two high-performance devices on each floor. In many cases, a fax machine is installed and shared by all employees.

However, with this type of configuration, work efficiency was poor because each time a facsimile transmission was performed, it was necessary to go to the location where the facsimile was installed, and if the facsimile was in use, the user had to go there again and send the facsimile.

Therefore, in order to improve work efficiency, for example, a system can be considered in which a facsimile main unit installed in the center is connected to a large number of facsimile handsets using signal lines, so that each handset can perform b-fax transmission and reception. However, in such a system, many signal lines must be laid between the main unit and a large number of slave units, which reduces installation efficiency, so it is necessary to develop a system that can improve both installation and workability. was awaited. [Invention tries to solve! ! The present invention, proposed in view of the above circumstances, uses wireless signals to transmit signals between a centrally installed facsimile base machine and a facsimile slave machine, thereby reducing the number of signal lines to be laid. The object of the present invention is to provide a wireless facsimile transmission/reception system that improves construction and workability by allowing facsimile transmission and reception to be performed on each handset side.

[Means for Solving the Problem] A facsimile transmission/reception system of the present invention proposed to achieve the above object includes a facsimile handset including at least an image reading section and a wireless transmission/reception section, and a facsimile handset connected to a telephone line. , consisting of a facsimile base machine equipped with at least a printout section and a wireless transmission/reception section,
The image signal read by the slave unit is transmitted to the base unit using a wireless signal, and the base unit receives and demodulates the transmitted wireless signal and sends the obtained image signal to the telephone line. ing.

In the basic system of the present invention, an image signal of a document read by one of the slave units is transmitted to the base unit via a wireless signal, and the base unit receives and demodulates the transmitted wireless signal to generate an image. Facsimile transmission is performed by sending signals to the telephone line, and all image signals transmitted via the telephone line are printed out on recording paper by the base unit, but in addition to this configuration, Also, an example is
One of the multiple slave units may be equipped with a print output section, and the image signal transmitted via the telephone line may be transmitted from the base unit to the slave unit using a wireless signal to be printed out. Register a data table that associates the sending source data with the slave device, identify the sending source data attached to the image signal received on the base device side by a method such as no\turn matching, and create the data table. '#In contrast, it is possible to adopt a configuration in which the image signal is transmitted by wireless signal to the corresponding handset and output as a printout.

[Operation] In the present invention, the image signal read by the 11-inch image reading unit is transmitted to the base unit side by a wireless signal, and the base unit receives and demodulates the transmitted wireless signal and receives the image signal. Facsimile transmission is performed by sending the data to the telephone line.

[Example] The present invention will be described in detail below with reference to the drawings.
