BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless facsimile machine equipped with a base unit and a slave unit that communicate with each other wirelessly.

0002

2. Description of the Related Art In recent years, facsimile machines have become very popular, and facsimile machines are often installed in offices.

0003

[Problem to be solved by the invention] However, in a large office where several people are present, the distance from each person's seat to the facsimile machine is long, and it is difficult to leave the seat and go to the facsimile machine every time you send a message. It's a hassle. Facsimile machines are often installed in corners of rooms due to telephone line limitations, and this also makes the facsimile machines far away. If you increase the number of facsimile machines installed,
Although they are convenient to use, facsimile machines each having independent functions have problems in that they are expensive, large in size, and require a large installation space.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cordless facsimile machine which can be used as a small and inexpensive handset and is suitable for use in which each person sends a message while sitting at his/her seat.

[0005]

[Means for Solving the Problems] The structure of the present invention will be explained with reference to FIG. 1 corresponding to an embodiment. This cordless facsimile machine consists of a main unit (1) and a sending unit (2).
It consists of The slave unit (2) is composed of a wireless unit (4) that communicates with the base unit (1), and an image data reading unit (3). The base unit (1) includes a wireless unit (7) that communicates with the slave unit (2), a code/decoder unit (11) that encodes and decodes image data, a recording unit (9), and a reading unit (10). ) and a communication unit (8) that communicates via the communication line network.
).

[0006]

[Operation] According to this configuration, the image data read by the reading unit (3) of the slave unit (2) is encoded by the code/decoder unit (11) of the base unit (1), and then the image data is encoded by the code/decoder unit (11) of the base unit (1). It is sent from the communication section (8) to the communication line network. The received image is recorded in the recording unit (9) of the base unit (1). Cordless handset(
2) is composed of a radio section (4) and a reading section (3), and does not have a recording section, a communication section, a code/decoding section, etc., so it can be miniaturized.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 and 2. This cordless facsimile device is composed of a base unit 1 and a plurality of slave units 2. Each handset 2 is a transmission-only device composed of a reading section 3 and a wireless section 4, and is provided with a control section 5 and an operation section 6 for controlling the reading section 3 and the wireless section 4. The reading section 4 includes an image sensor such as a CCD and a document feeder. The wireless unit 4 is the base unit 1
Communication between the computer and the computer is performed wirelessly instead of using a code, and image data is transmitted and control signals are transmitted and received. The operation unit 6 is composed of a group of key switches for dialing and for starting and stopping transmission.

[0008] The base device 1 has functional means for use with the handset 2, such as a wireless unit 7 for communication with the handset 2 and an image storage memory 12, in addition to the functional means as a general facsimile machine. It is. The main device 1 basically includes a communication section 8, a recording section 9, a reading section 10, and a code/decoding section (CODEC) 11.
, the wireless section 7 , and an image storage memory 12 , which are controlled by the control program of the main control section 17 and the operation of the operation/display section 15 .

The main control section 17 is composed of a CPU, a ROM in which a control program is written, and a RAM serving as a working storage area and the like. The communication unit 8 includes a network control unit (NCU) 13 and a modem 14 connected to a line 18 . The operation/display section 15 includes a numeric keypad for dialing,
Consists of various function keys for starting and stopping transmission, etc.
A liquid crystal display device and the like are provided. The recording unit 9 includes a printer that prints the received image on recording paper. The reading section 10 includes an image sensor and a document feeder. The code/decoder 11 is a means for code-compressing image data for transmission and sending it to the modem 14, as well as decoding received image data. The image storage memory 12 is a memory device that stores image data transmitted from the handset 2. The additional function means 16 is
This figure is representative of various additional function means that perform speed dialing, sender display, etc.

The usage and operation of the above configuration will be explained. When transmitting from the handset 2, the dial number of the destination is input on the operation section 6, and the reading section 3 is caused to read the document. The dial number input may be a number using a speed dial function of base unit 1 or the like. The dial number data and the read image data are transmitted from the wireless unit 4 to the wireless unit 7 of the base unit 1.

As shown in FIG. 2, the base unit 1 stores the dial number data received by the wireless unit 7 in a predetermined memory area of the main control unit 17 (S1), and converts the image data into an image. It is temporarily stored in the storage memory 12 (S2). Thereafter, the transmission priority is determined (S3), and if it is the first priority, the network control device 13 sends out a dial signal based on the stored dial number data (S3).
4).

[0012] The transmission priority order is from multiple slave units 2 to base unit 1.
Appropriate settings are made in the main control unit 17 depending on the case where image data is stored in the image storage memory 12 due to transmission to the main unit 1, the case where the main unit 1 is used, the case where redialing is to be performed, etc. When not transmitting from other handset 2 or base unit 1,
Immediately after image storage, a dial signal is sent out. When reception becomes possible (S5) by sending the dial signal (S4), that is, when the line is connected and a reception ready signal is detected from the called terminal, an image is stored corresponding to the dial number. The image data stored in the memory 12 is sent out (S6). In this case, the image data is compressed by the code/decoder 11 and sent from the modem 14. Note that the data may be compressed and stored in the encoder/decoder 11 when the data is stored in the image storage memory 12.

[0013] In the determination process of step S5, if the destination is in a state where reception is not possible, such as when the destination is busy, the priority order is waited again (S3) and redial is performed. In this way, transmission from handset 2 is performed. The received image is printed by the recording unit 9 of the base unit 1.

[0014] In this cordless facsimile device, the handset 2 is a transmission-only device consisting of the radio section 4 and the reading section 3, so the construction of the handset 2 is simple, small, and inexpensive. . Therefore, even if the handset 2 is installed on each person's desk in the office, the handset 2 does not get in the way, and each person can send a document while remaining at their seat. In addition, a telephone is generally installed on the desk, and the line is often separate, so you can make calls and send documents at the same time while sitting at your desk. Furthermore, since the image storage memory 12 is used, transmission from a plurality of handsets 2 can be conveniently performed.

In the above embodiment, the handset 2 is provided with the operating section 6 for inputting a dial number, but the handset 2 does not necessarily need to be provided with dialing means. For example, if the destination is always the same, the dial number of the destination of the handset 2 may be set in the base device 1.

[0016]

[Effects of the Invention] The cordless facsimile device of the present invention is composed of a base unit and a slave unit, and the slave unit is a transmitting-only machine consisting of a wireless unit that communicates with the base unit and a reading unit. It will be small and cheap. Therefore, even if the handset is installed on each person's desk or the like, it does not get in the way, and it is possible to realize a usage pattern in which each person can send data while remaining at their seat.
