【Example】

 Next, a preferred embodiment of the facsimile broadcast receiver according to the present invention will be described with reference to the drawings.

FIG. 1 shows a functional block diagram of the facsimile broadcast receiver according to the embodiment. The facsimile broadcast receiver of the embodiment can be realized by the hardware configuration shown below.

In FIG. 1, the facsimile broadcast receiver includes a CPU 1 that outputs a control command to all components of the receiver, a ROM 2 that stores a program for controlling the apparatus, and the contents of the received facsimile broadcast. Is stored, switching information for operating one or more of printing, storage, and display, reservation setting information for preset setting of broadcast programs, etc. is stored, and information obtained by receiving a facsimile broadcast is temporarily stored. RAM 3 (switching means, storage means, accumulating means) for temporarily storing or accumulating, decoding section 4 for decompressing the compressed and transmitted code string, and receiving mechanism section for controlling the paper feeding of the recording paper of printing section 9. 8, a printing unit 9 (printing means) for printing the content of the received facsimile broadcast, and a control for switching printing, storage, or display of the facsimile broadcast program. A keyboard 10 (setting means) for data input for setting and program reservation reception setting of a facsimile broadcast program in a desired time zone and data input for operating one or more of printing, storing, and displaying ), A tuner 7 for converting a facsimile broadcast signal modulated into a high-frequency signal into an IF signal for detection, and demodulation for DQPSK (differential 4-phase phase modulation) etc. with respect to the detection output of the tuner 7. A demodulator 6 (demodulation means), an error correction unit 5 that performs a code error correction on a demodulated output output from the demodulator 6 by using an error correction method, and a received facsimile broadcast content on a liquid crystal display. It is composed of a display unit 11 (display means) for displaying using a display device or the like.

Next, the operation of the facsimile broadcast receiver according to the embodiment will be described below. Facsimile signals multiplexed with a television signal are transmitted, and the transmitted fax is a high-frequency signal output from the antenna that is received by the receiver's conventional popular antenna for receiving television broadcasting. Is supplied to the tuner 7.

The high frequency signal supplied to the tuner 7 is converted into an IF signal and detected, and then the detected signal is supplied to the demodulator 6 and demodulated for DQPSK or the like. The demodulated output is supplied to the error correction unit 5 to perform error correction of the code and supply the code to the decoding unit 4 to expand the compressed code string to restore the facsimile data. After that, according to the information from the RAM 3, the restored facsimile data is supplied to the printing unit 5 for printing, or stored and accumulated in the RAM 3, or supplied to the display unit 15 for display. Is done.

Next, the operation of switching between printing, storing, and displaying will be described with reference to the operation flowchart of FIG. First, the CPU 1 determines whether or not to receive a facsimile broadcast (step 20). If it is received, the process proceeds to broadcast reception (step 30). If not, it is determined whether or not to switch the mode (step 40). ).

In receiving the broadcast in step 30, first, a facsimile signal is extracted from the demodulator 6 (step 31). Next, the extracted facsimile signal is supplied to the error correction unit 5 to correct the code error, and the decoding unit 4 expands the code (step 32). Next, the facsimile data restored on the basis of the switching information stored in the RAM 3 is supplied to the printing unit 9 for printing (this processing is called hard copy) or is supplied to the display unit 11 for display. (This process is referred to as soft copy) or the process of accumulating in the RAM 3 is selected (step 33). If the switching information for the hard copy is stored in the RAM 3, the facsimile data is supplied to the printing unit 9 in step 34, and printing is performed by the paper feeding operation of the receiving mechanism unit 8. If the switching information for the soft copy is stored in the RAM 3, the facsimile data is supplied to the display unit 11 and displayed in step 35. Alternatively, when the switching information for storage is stored in the RAM 3, facsimile data is stored in the RAM 3 in step 37.

Next, it is confirmed whether the soft copy, hard copy, or storage of one page of facsimile data has been completed, and further whether there is a next page (step 36). Repeats steps 31 to 37 again to perform hard copy, soft copy, or accumulation. When it is confirmed that the reception process of the last page is completed, the process returns to step 20 again, and it is determined whether or not the broadcast is continuously received.

If it is determined in step 40 that the mode is to be switched, the process proceeds to step 50, and if the mode is not switched, the process returns to step 20.

In the mode switching in step 50, it is first determined whether the soft copy mode, the hard copy mode, or the storage mode is selected (step 51). Data is input from the keyboard 10 or the like and the switching information for selecting the soft copy mode is stored in the RAM 3 (step 52), or the switching information for selecting the hard copy mode is stored (step 53), or accumulation is selected. The switching information is stored (step 54).

When the above step 52, 53 or 54 is completed, the process returns to step 20 again and it is judged whether or not the broadcast is continuously received.

As described above, by inputting desired switching information from the keyboard 10 or the like and storing it in the RAM 3, the printing state is switched to print only when printing is necessary, and when printing is not necessary, display or storage is performed. Since it can be switched to the state, the amount of recording paper consumed in printing can be reduced, and the memory capacity can be reduced when printing is performed after storing in the RAM 3.

Next, the operation of making a program reservation and performing hard copy, soft copy, or accumulation will be described using the operation flowchart of FIG. First, it is determined whether or not a facsimile broadcast is received (step 25). If it is received, the process proceeds to step 70. If it is not received, the process proceeds to step 80, at which it is determined whether or not to make a program reservation. When making a reservation, the process proceeds to step 90 to perform the reservation process, and when not making the reservation process, returns to step 25 again.

In the program reservation processing of step 90, first, information such as a desired facsimile broadcast program number is input from the keyboard 10 or the like (step 91). Next, it is judged which mode such as soft copy, hard copy or accumulation is selected (step 92), data is input from the keyboard 10 or the like, and switching information for selecting the soft copy mode is stored in the RAM 3 (step). 93), or switching information for selecting the hard copy mode is stored (step 94), or switching information for selecting accumulation is stored (step 95). When the above setting is completed, the process returns to the step 25 again to judge whether or not to receive the broadcast, and if so, the process proceeds to step 70 to perform the broadcast receiving process.

Note that FIG. 4 shows an example of a program table in the case of a facsimile broadcast program reservation. The program table includes (1) a part that sets the presence or absence of reservation, (2) a part that sets the program number, and (3) a part that sets the mode (hard copy, soft copy, or accumulation). Has been. In addition, a section for setting the broadcast start time, broadcast time, etc. may be provided. The data is set in this way and stored in the RAM 3. In the example of FIG. 4, “program number 123 is reserved by hard copy” is set.

In the broadcast receiving process of step 70, the RAM 3 is first checked to see if the reservation number has been input (step 71). If it has been input, the process proceeds to step 72 and the demodulator 6 outputs the reservation number. The facsimile signal of the program number corresponding to the program number (eg "123") in the program reservation table is extracted. Next, this signal is supplied to the error correction section 5 for error correction, and then it is supplied to the decoding section 4 to decompress the code and restore the facsimile data (step 73). Next, the program reservation table is confirmed (step 74), and it is then determined whether soft copy, hard copy, or accumulation is to be performed (step 75). In the case of a hard copy, the facsimile data is supplied to the printing unit 9 for printing (step 76), and in the case of a soft copy, it is supplied to the display unit 11 for display (step 77), or the accumulation is performed. If so, it is stored in the RAM 3 (step 78). As described above, it is confirmed whether reception of one page of the reserved program is completed and whether there is a next page (step 79). If there is a next page, the processes of steps 72 to 78 are repeated again. To receive. When the reception of the set reserved program is completed, the process returns to step 25, and it is confirmed whether or not the broadcast is to be received. If not, the process proceeds to step 80, and whether or not the program is reserved is confirmed. If not, the process returns to step 25 again.

As described above, by setting information such as a program number related to a desired facsimile broadcast program in advance, the program number of the broadcast program to be printed, displayed, or stored, the broadcast start time, the print, display, or storage By setting the presence / absence, it is possible to automatically print, display, or store the desired facsimile broadcast program based on this information, thus saving the amount of recording paper and memory used. In addition, it is possible to obtain the information of the desired program without fail even if the user is away during the broadcast time.

In FIG. 2 and FIG. 3 of the above embodiment, any one of print, display and storage is selected for operation, but it is also possible to set to operate a plurality of these. Although an example in which the received information of the facsimile broadcast is stored in the RAM has been described with reference to FIGS. 1 to 3, it is also possible to store it in another storage medium. Alternatively, the display unit 11 in FIG. 1 may use a plasma display, a CRT display, or the like.
