1 is a block diagram showing an embodiment of a preset type radio receiver according to the present invention. Figure 1
, 1 is an antenna, 2 is a tuner section, 3 is a PL
L part, 4 is a system controller including a microcomputer, 5 is a key input part, 6 is a rotary encoder, and 7 is a display part.

The basic operation of the preset receiver configured as described above is as follows. The reception signal received by the antenna 1 is input to the tuner unit 2 where it is detected and demodulated and an audio signal is output. The local oscillator of the tuner unit 2 is controlled by the system controller 4 via the PLL unit 3,
To receive. Further, under the control of the system controller 4, in the preset channel memory mode, a plurality of preset channel numbers and reception frequencies set by the ten keys included in the key input unit 5 or the rotary encoder 6 are stored in an internal memory (or an external memory (not shown)). Memory).

When receiving by the preset channel, that is, when receiving and storing the stored reception frequency by operating the preset channel, the stored preset channel number and reception frequency are recalled at any time by operating the keys of the key input unit 5 or the like. Then, reception by the preset channel is performed. Further, in the preset channel memory mode or during preset reception, the preset channel number and the reception frequency of the display unit 7 are displayed.

In the preset receiver having the above structure and basic operation, the following operation is performed according to the present invention. During preset reception, when the memory key of the key input unit 5 is pressed while the preset channel number currently being received is displayed on the display unit 7, the current preset channel number being displayed is controlled by the system controller 4. The display will blink.

Further, under the control of the system controller 4, when reception is not preset reception (for example, manual tuning reception, auto tuning reception, etc.), a bar display ("-") is displayed at the preset channel number display location on the display unit 7. However, when the memory key of the key input unit 5 is pressed, instead of the bar display (“−−”), the minimum number of the empty preset channel numbers which the user does not memorize blinks.

The operation in the preset channel memory mode using the above display will be described below.

First, at the time of preset reception, as shown in FIG. 2A, for example, the modulation type (for example, "FM"), preset channel number (for example, "08") and reception frequency (for example, "" are displayed on the display unit 7. 88.00 MH
z ″) is displayed.

Next, when the memory key of the key input section 5 is pressed while the preset channel number is lit and displayed,
As shown in FIG. 2B, a mark indicating that the preset channel memory mode has been entered (for example, the character "MEMO", but not limited to this, may be a figure or the like) is lit up on the display unit 7. At the same time, the preset channel number (for example, "08") is displayed blinking.

Next, when the rotary encoder 6 is rotated, the system controller 4 changes the preset channel number of the display section 7 based on the signal from the rotary encoder 6. FIGS. 2C and 2D show an example in which the rotary encoder 6 is rotated in the up direction and the preset channel number is changed from “08” currently being received to “09” to “12”. There is.

Next, when the preset channel number "12" is displayed on the display section 7, the memory key of the key input section 5 is pressed again, and as shown in FIG. At the same time that the mark "MEMO" being displayed on the display unit 7 is turned off, the same frequency "88.00 MHz" as the reception frequency of the preset channel of the preset channel number "08" is preset channel number "12" in the internal memory. Is stored as a reception frequency in the place of

Next, in the case of reception other than preset reception, for example, auto tuning reception, the display unit 7 displays the modulation type (for example, "F" as shown in FIG. 3A).
M ”), bar display (“ −− ”) at the preset channel number display location, and reception frequency (eg,“ 88.00 ”).
MHz ”) is displayed.

Next, when the memory key of the key input section 5 is pressed while the bar display ("---") is lit, FIG.
As shown in, a mark indicating that the preset channel memory mode has been entered on the display unit 7 (for example, the character "M
EMO ”, but not limited to this, it may be a figure or the like), and at the same time, the minimum number (for example,“ 13 ”) of the empty preset channel numbers is displayed instead of the bar display (“ −− ”). Flashes.

This free preset channel number is a preset channel (ie, auto memory, auto preset, manual memory, etc.) in which the user does not store the reception frequency among a plurality of preset channels stored in the internal memory. Not a free channel) means a number.

Next, while the preset channel number "13" is displayed on the display unit 7, the memory key of the key input unit 5 is pressed again, and the system controller 4 is pressed.
By the control of, the mark "MEMO" displayed on the display unit 7 is turned off and at the same time the preset channel number "1" is displayed.
3 ”is switched from blinking display to lighting display.
The reception frequency "88.00 MHz" currently being received is stored as a reception frequency in the location of the preset channel number "13" in the built-in memory.

FIG. 4 is a conceptual diagram for explaining the minimum preset channel number called at the time of reception other than preset reception. (A) shows, for example, 10 preset channels, of which 01ch to 08c.
If the reception frequency is already stored in memory up to h (the diagonal line indicates the preset channel in which the reception frequency is already stored), the minimum number is 0.
Indicates that 9ch is called.

Further, (B) shows a case where there are preset channels of, for example, 10 stations, of which the reception frequencies are already discontinuously stored in the channels other than 04ch, 06ch and 10ch (represented by diagonal lines), It indicates that 04ch of 04ch, 06ch and 10ch is called as the minimum number.

Next, FIG. 5 is a flow chart showing the operation of the preset channel memory when the ten keys are used in the block diagram of FIG. First, in S1, it is determined whether or not the memory key is turned on. If NO, the operation is ended, and if YES, the process proceeds to S2, and a built-in timer of the system controller 4, for example, a 5 second timer is set, and then in S3, It is determined whether or not the 5-second timer has timed out. If the result is YES, the work is ended, and if the result is NO, the process proceeds to S4.

In S4, it is determined whether or not the preset channel is displayed. If YES, the process proceeds to S5 to display (or blink) the current preset number,
Then, it proceeds to S7. If the answer to S4 is no, go to S6,
Display the lowest unregistered preset number, then S
Proceed to 7. In S7, it is determined whether or not the numeric keypad is turned on (that is, the manual tuning is performed),
If yes, proceed to S8; if no, proceed to S9.

In S8, it is determined whether or not the numeric keypad is valid. If YES, the process proceeds to S12, the preset channel of the pressed numeric keypad is memorized, and the operation is finished. If the answer to S8 is no, the process returns to S2.

In S9, it is determined whether or not the memory key is turned on. If NO, the process returns to S3, and if YES, S1.
Proceed to 0 to determine whether the memory key is valid. S1
If the answer to 0 is yes, the process proceeds to step S11, notes the preset channel being displayed, and then ends the operation. If the answer to S10 is no, the process returns to S2.

FIG. 6 is a flow chart showing the operation of the preset channel memory when the rotary encoder is used in the block diagram of FIG. First, in S21, it is determined whether or not the memory key is turned on. If NO, the operation is ended, and if YES, the process proceeds to S22, and the 5 second timer is set. Then, in S23, whether the 5 second timer has timed out. It is determined whether or not, and if the result is yes, the work is ended, and if the result is no, the process proceeds to S24.

In S24, it is determined whether or not the preset channel is displayed. If YES, the process proceeds to S25, the current preset number is displayed (or blinks), and then the process proceeds to S27. If the answer to S24 is no, the process proceeds to S26, the unregistered minimum preset number is displayed, and then the process proceeds to S27. In S27, it is determined whether or not the memory key is turned on, and if the result is YES, the process proceeds to S28, the preset channel being displayed is memorized, and the operation is finished. If the answer in S27 is no (that is,
If it is manual tuning), the process proceeds to S29, and it is determined whether the encoder is up.

If the answer in S29 is yes, proceed to S30,
The preset number is incremented by 1, and then the work is finished.
If the answer to S29 is no, the process proceeds to S31 to determine whether the encoder is down. If the answer in S31 is yes, proceed to S32 and set the preset number to -1.
Then, the process returns to S22. If the answer in S31 is no, the process returns to S23.

As described above, according to the present invention, (1) when presetting a station frequency (reception frequency) received by auto tuning,
You can see at a glance the channels except the preset channels that have already been memorized by auto preset, manual memory, etc. (2) When preset frequencies of station frequencies received by auto tuning are sequentially stored (for example, in order of increasing frequency), they can be stored in sequence without pressing the ten keys many times. (3) If you want to store the same frequency as the reception frequency registered in a certain preset channel in another preset channel, the preset channel number currently being received does not disappear even if you enter the preset channel memory mode, and it blinks. So I will never lose track of that number. (4) It is possible to prevent erroneous storage of a frequency different from the reception frequency stored in the past.
