CONSTITUTION:The operation section 4 is provided with a power switch 4a, a display changeover switch 4b, and a preset key 4c or the like. The display changeover switch 4b switches the display of the reception broadcast station into the frequency or the station name. For example, the display of the broadcast station such as 1431kHz in the broadcast frequency and RFC in the station name is switched as 1431 RFC 1431 ... at every depression of the display changeover switch 4b. Thus, either the frequency or the station name is displayed on the display section 3 by the display changeover switch 4b, then the station name of the reception broadcast station corresponding to the frequency is displayed.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a method for displaying the name of a received broadcasting station that can display the station name, and particularly relates to a method for displaying the name of a received broadcasting station that can display the name of a received broadcasting station on the same frequency based on a regional code. Regarding the station name display method.

<Prior Art> Conventional radio receivers display tuned reception stations using their broadcast frequencies.

<Problems to be Solved by the Invention> Since such radio receivers display only the broadcast frequency of the receiving station, 1. For example, when receiving radio in a service area other than the service area where you normally listen to radio, you may have to temporarily tune in to the broadcasting station. However, the problem was that listeners were forced to judge the name of the broadcasting station by themselves. In other words, if the name of the broadcasting station is unknown, during a long drive by car, etc., will the received station become stronger or weaker as the station progresses?

There is also the problem that it is impossible to judge whether or not information on the destination (traffic information, weather, etc.) can be obtained by continuing to listen to the broadcast station.

From the foregoing, a first object of the present invention is to provide a method for displaying the name of a receiving broadcasting station that can display the name of the receiving broadcasting station.

By the way, when displaying the station name of the receiving broadcast station, if there is a broadcast station that uses the same frequency in area A and area B, it is important to know whether the station is from area A or B. There is a concern that it may not be possible to identify the station.

In light of the above, a second object of the present invention is to provide a method for displaying the names of receiving broadcasting stations that can identify the names of receiving broadcasting stations on the same frequency based on the regional code that specifies the service area.

<Means for Solving the Problems> FIG. 1 is a block diagram of the main parts of a radio receiver that can realize the present invention.

1 is the main body of the radio receiver, 2 is the CPU, 3 is the display section, 4 is the operation section having a display changeover switch 4b, etc., 4c is a preset key serving as an input means, 5 is a frequency/station name correspondence table, and 6 is a It is a regional code memory.

Function> In the present invention, the receiving broadcasting station displays either the frequency or the station name on the display section 3 by switching the display changeover switch 4b.
will be displayed. Note that the name of the receiving broadcasting station using the same frequency is identified based on the regional code inputted from the preset key 4c.

<Embodiment> FIG. 1 is a block diagram of the main parts of a radio receiver that can realize the present invention.

In the figure, 1 is the main body of a radio receiver, including an antenna 1a and an electronically tuned tuner section 1b.

It has a PLL synthesizer 1c, a power amplifier ld, a speaker 1e, etc.

A CPU 2 is in charge of overall control, and performs processes such as displaying the names of received broadcasting stations, which will be described later. 3 is a display section, 4 is an operation section, and is a power switch 4a.

Display changeover switch 4b, preset key 4c (1 to 1)
etc. The display changeover switch 4b switches the display of the received broadcasting station to either the frequency or the station name. For example, the broadcasting frequency is 1431kl (z.

The display of a broadcasting station whose station name is RFC changes from 1431→RFC→1431→・each time the display changeover switch 4b is pressed.
It can be switched as follows.

5 is a frequency/station name correspondence table, which is a ROM in which station names corresponding to each frequency are stored in advance for each region. Reference numeral 6 denotes a regional code memory, which is a ROM in which a unique code (regional code) assigned to each divided service area when the service area is divided into regions is stored in advance. FIG. 2 is a diagram for explaining regional codes. As shown in the figure, the service area in Japan is divided into, for example, areas A to F, and numerical values 1 to 6 are assigned as codes for each area.

Then, by inputting a regional code using the preset key mount to date, the broadcasting station name of the receiving frequency is identified using the frequency/station name correspondence table 5 corresponding to the region specified by the regional code. In addition, the instruction of the regional code using the preset keys (1) to (5) is performed by changing the function of the preset key 4c to the regional code entry key by, for example, holding down the display changeover switch 4b for 2 seconds or more. It will be done. For example, in the case of the A (Hokkaido) area, by inputting the preset key ■, the CPU 2 will call up the station name of the service area corresponding to the received frequency from the frequency/station name correspondence table 5 of the A area. Even if you move to.

By specifying the area code, the service area settings can be updated and the station name of each service area corresponding to one frequency can be identified.

FIG. 3 is a flowchart of processing showing one embodiment of the present invention.

First, it is determined whether or not there is an instruction to change the service area by holding down the display changeover switch 4b for 2 seconds or more (Step 101), and when the instruction is given, the service area is changed according to the preset key 0-El (region code) that is input. Update step 102), if "r station name display mode".

Thereafter, using the updated service area frequency/station name correspondence table 5, select the broadcasting station name corresponding to the received frequency and display it on the display section 3, and if it is in the "frequency display mode", the received frequency will be displayed ( Step 103).

Next, tuning is performed (step 104), and by selecting the display with the display changeover switch 4b (step 105),
Display the station name or frequency of the receiving broadcasting station (step 1.0)
6,107), the process ends.

On the other hand, if there is no instruction to change the service area as determined in step lot, the process jumps to step 104.

Continue the subsequent processing.

In addition, when tuning in step 104, if the frequency is displayed regardless of the display selection of the display changeover switch 4b, the position within the band being tuned can be easily understood.

FIG. 4 is a block diagram showing another embodiment in which the present invention can be implemented.

In the figure, the same reference numerals as in FIG. 1 indicate the same or corresponding parts, 11 is an anti-theft system, an operating section 12. C
It has a PU 13, an anti-theft coat memory 14, and the like.

The operation unit 12 has a numeric keypad t2a (El~ times), and an anti-set code that becomes a password is input when the device is started.

The CPUI 3 enables normal operation of the device main body 1 only when a specific password (Anti Theft Code) is input.

The anti-theft code memory 14 stores a device-specific anti-set code at the factory manufacturing stage or by the user.

The operation of FIG. 4 will be explained below.9 The anti-set code in this embodiment is constructed by adding a regional code, and is used to cancel the anti-set and identify the name of the receiving broadcasting station on the same frequency.

As shown in (1) below, the ant set code is composed of a 6-digit code in which the first digit is a regional code and the remaining 5 digits are an anti-set code.

123456 (1) For example, if the first digit of this anti-set code is the regional code “1
” is input, the CPU 2 refers to the region code memory 6 and identifies the station name of the receiving frequency using the frequency/station name correspondence table 5 corresponding to the region indicated by the region code “1”.

In other words, the A area shown in Figure 2 can be accessed using the numeric keypad l.
The service area for district B is designated by the numeric keypad ■, and the service area for district F is designated by the numeric keypad date. For example, B(
In the case of the Tohoku region, when the first digit is input using the preset key, the CPU 2 calls the station name of the service area corresponding to the frequency from the frequency/station name correspondence table 5. Then, the station name is displayed on the display section 3.

In addition, in the above embodiment, the regional code was set to 1 digit, but it was set to 2 digits.
It does not matter if it is a code with more than digits.

Further, the anti-set code may also have a number of digits other than the above.

<Effects of the Invention> According to the present invention, a display changeover switch is provided to switch and display the frequency or station name of the received broadcasting station, and the display changeover switch is configured to display either the frequency or the station name. Therefore, it is possible to display the station name of the receiving broadcasting station corresponding to the frequency.

In addition, the service area is divided into regions, a unique code is assigned to each divided service area, and by inputting this regional code from the input means, the receiving broadcasting station on the same frequency can be named based on the regional code. Since the system is configured to identify the received broadcasting station name and display the received broadcasting station name, it has the excellent advantage that even if the broadcasting station uses the same frequency, the received broadcasting station name can be identified based on the regional code that specifies the service area. has.
