[Prior art]
Radio teletext broadcasting began in October 1994, and has been broadcast throughout the country since April 1995. The contents of the broadcast programs are also “news, sports and weather forecasts”, “text broadcasting linked with audio broadcasting”, “traffic information”, and “entertainment related”. Recently, the latest information has been provided to viewers by continuously sending traffic jam information via teletext. In the more advanced version, such information is input to the car navigation system and the driver can It is displayed so as not to accidentally enter a crowded area. As means for this, a radio receiving circuit, a circuit for characterizing a program-linked character broadcast signal, and a structure for outputting the characterized information to the liquid crystal display unit while temporarily storing the information in the memory means. The radio receiver can select a favorite information channel. In addition, the standard transmission system for ultra-short-wave character multiplex broadcasting is published in the official gazette, and each manufacturer makes a receiver according to such a system.

[Problems to be solved by the invention]
However, since such a conventional teletext receiver is manufactured on the premise that the viewer is by the radio in principle, the storage means is about a temporary storage as a buffer , and the stored data All reproduction etc. are not considered. Further, it is sufficient that the text information can be visually confirmed, and it is not considered to make the information paper-down. Furthermore, since it is assumed that the viewer is beside the radio receiver, there is no device that receives and stores necessary information by remote operation or reservation operation when necessary.
Accordingly, the present invention has been made in view of the drawbacks of the prior art, and can store character information in a predetermined program at a predetermined frequency for a predetermined time by a reservation operation. The stored data is displayed on a display unit of a radio receiver. In addition to the above, it is an object to provide a multi-function radio teletext receiver that can be displayed on a large display and output to a fax machine or a printer.

[0013]
The operation of the receiver and the operation of the receiver according to the present embodiment in the above-described configuration will be described with reference to the flowcharts shown in FIGS. In the present embodiment, a reservation for reception of text broadcast is made using the operation unit 28 or a telephone line.
Contents to be reserved include date and time, start time, end time, frequency, program name, and the like. The reservation using the telephone line is made by transmitting a DTMF signal from the telephone according to the voice guidance flowing from the voice guidance processing means 36 when connected via the telephone interface 30 as shown in FIG. It is converted into an instruction command by the signal conversion means 32, and the start date, start time, end time, frequency, etc. are stored in the work RAM 38 as reserved contents.
[0014]
Information input from the operation unit 28 or the like is stored in the work RAM 38 via the CPU 22. When the time elapses and the reserved time is reached, the CPU 22 operates based on the information stored in the work RAM 38, switches the radio reception circuit 1 from OFF to ON, and receives a character broadcast of a predetermined channel and a predetermined program. Make it ready. When the reservation content is data storage, the changeover switch 6 connects the output terminal 4a of the characterizing circuit 4 and the input terminal of the storage means 20 and puts them in an energized state. In such a state, the characterizing circuit 4 converts the signal relating to the character detected by the radio receiving circuit 1 into characterized data using the character font set 5, and stores the data while the memory capacity is sufficient. 20 is stored in memory.
Then, when the reserved end time is reached, the radio reception circuit 1 is switched from ON to OFF and the input of data to the storage means 20 is blocked. As a result, the storage unit 20 is in a state where necessary information of a predetermined program of a predetermined channel is stored.
[0015]
Next, when the owner of the receiver wants to check the information stored in the storage means 20, the receiver according to the present embodiment selects whether to output and paper down or display on the display 7 or the like. (Fig. 4). That is, the display unit or the output is first selected by operating the operation unit 28. When the output is selected, the printer interface 16 and the facsimile interface 18 are provided as output terminals. 14 connection locations are selected.
