DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selection device, and more particularly to a selection device capable of selecting a large number of selection items by operating one key.

[0002]

2. Description of the Related Art In recent years, various portable AV devices and portable information terminals have complicated functions. However, since a large operation space cannot be obtained, a large number of selection items can be selected by operating one key. For example, in a portable radio with a preset reception function shown in FIG. 6, n (n is an integer of 2 or more) preset channels CH1 to CHn for AM.
And m (m is an integer of 2 or more) preset channels CH1 to CHm for FM.
When an arbitrary channel can be called up by a key operation on the reception frequency data FD (A) for each of the n AM preset channels CH1 to CHn, the channel memory 3 of the system controller 2 of the microcomputer configuration can be called.
M) 1 to FD (AM) n are registered as selection items of the first group, and m preset channels CH1 for FM are registered.
To CHm, reception frequency data FD (FM) 1 to FD
(FM) n is registered as a selection item of the second group (see FIG. 8).

In accordance with the flowchart shown in FIG. 7, the system controller 2 enters a standby mode in an initial setting after the power is turned on (step S10). When a key operation is performed by pressing the key 1, the key operation is continued for the key pressing duration. The time T is monitored, and a predetermined reference time T ₀ (for example, T ₀ =
When 0.4 sec) shorter key operation is the first selection mode is determined to the desired channel call for AM (YES at step S11 and S12, S13), the long key operation is being than the reference time T ₀ And it is determined that the channel call for FM is desired, and the second selection mode is set (YES in step S11, NO in S12, S2
0).

In the first selection mode, the system controller 2 controls the AM / FM radio receiver 4 to switch to the AM reception mode (step S14).
From the first group of selection items registered in the channel memory 3, the first one, the preset channel CH1, is selected, and the reception frequency data FD (AM) 1 stored in association with the CH1 is read out. The signal is output to the AM / FM radio receiver 4 and tuned to the frequency indicated by the FD (AM) 1 (steps S15 and S16). After that, the key 1
Each time a key operation is performed once, one preset channel CH for the youngest AM that has not been selected yet
i (where i = 2 to n), sequentially read out the corresponding reception frequency data FD (AM) i, output it to the AM / FM radio receiver 4, and tune to the frequency indicated by FD (AM) i (YES in step S17, NO in S18,
S19 and S16 are repeated). Under the first selection mode, (n
-1) The key is operated once, and if there is no unselected preset channel in the AM, if the key is operated once more, the system controller 2 returns to the original standby mode (step S17 and step S17). YES at S18, S1
0).

[0005] Then, if you want to channel calls for FM, the long key operation than the reference time T _0. Then, it is determined that FM channel calling is desired, and the second selection mode is set (YES in step S11, S12
No, S20). In the second selection mode, the system controller 2 sends an FM / FM radio signal to the AM / FM radio receiver 4.
After controlling the switching to the reception mode (step S2
1) Preset channel CH1 which is the first of the second group selection items registered in channel memory 3
Is selected, the reception frequency data FD (FM) 1 stored in association with the CH1 is read out, output to the AM / FM radio receiver 4, and tuned to the frequency indicated by the FD (FM) 1 (step S22). , S23). Thereafter, each time the user performs one key operation on the key 1, one of the preset channels CHi (where i = 2 to m) for the youngest FM which has not been selected is selected in order. To read the received frequency data FD (FM) i
The signal is output to the M radio receiver 4 and tuned to the frequency indicated by FD (FM) i (YES in step S24, N in step S25).
O, S26 and S23). In the second selection mode, the key operation is performed (m-1) times, and if there is no unselected preset channel in the FM channel, if the key operation is performed once more, the system controller 2 returns to the original. Return to the standby mode (YES in steps S24 and S25, S1
0). In this way, the user can perform any one of the AM channel calling operation and the FM channel calling operation by simply performing a key operation on one key.

[0006]

However, for example, if the user wants to call the channel for FM, but accidentally operates the key in the standby mode for a short time and the first selection mode is selected, the key is pressed n times. Without the operation, it was not possible to return to the original standby mode, which was very inconvenient. Also, for example, when the second preset channel for AM is selected in the first selection mode, and when it is desired to call the channel for FM, (n-1)
Unless the key operation is performed twice, it is not possible to return to the original standby mode, which is very inconvenient. The present invention has been made in consideration of the above-described problems of the related art, and has as its object to provide a selection device capable of easily selecting a desired item.

Next, one embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing a configuration of a portable radio according to the present invention, and the same components as those in FIG. 6 are denoted by the same reference numerals. Reference numeral 1 denotes a key, which outputs an H-level key signal only while the key is pressed. By operating key 1, the user can perform a channel calling operation for AM and FM. 4 is AM
/ FM radio receiving unit, which switches the receiving mode between the AM mode and the FM mode and changes the tuning frequency under the control of a system controller described later. 2A
Is a system controller composed of a microcomputer, and key 1
Performs channel call reception control for the AM / FM radio receiver 4 in response to the key operation of. In the channel memory 3 of the system controller 2A, reception frequency data FD (AM) 1 to FD (AM) n are registered as selection items of a first group for each of n preset channels CH1 to CHn for AM. Further, the reception frequency data F is divided into m preset channels CH1 to CHm for FM.
D (FM) 1 to FD (FM) n are registered as selection items of the second group (see FIG. 8).

FIG. 2 is a flowchart showing a channel call reception control process of the system controller 2A. The operation of this embodiment will be described below with reference to FIG. The system controller 2A enters the standby mode in the initial setting after the power is turned on (step S10 in FIG. 2). Then, the key signal input from the key 1 is checked, and the key 1
If there is an H-level key signal input due to pressing of the key, it is determined that there is a key operation (YES in step S11), and then a key operation time T, which is the duration of the H-level key signal input (key pressing duration). When a key operation shorter than a predetermined reference time T ₀ (for example, T ₀ = 0.4 sec) is performed, it is determined that a channel call for AM is desired, and the first selection mode is set (YES in step S12).
S13), when the long key operation is than the reference time T ₀ F
It is determined that the channel call for M is desired, and the second selection mode is set (NO in step S12, S20).

In the first selection mode, the system controller 2A controls the AM / FM radio receiver 4 to switch to the AM reception mode (step S1).
4) The first one of the first group of selection items registered in the channel memory 3, ie, the preset channel CH1
Is selected, the reception frequency data FD (AM) 1 stored in association with the CH1 is read out, output to the AM / FM radio receiver 4, and tuned to the frequency indicated by the FD (AM) 1 (step S15). , S16). Even after the first selection mode has been entered, the system controller 2A monitors the key operation time when the key 1 is operated.
Every time a key operation shorter than ₁ (for example, T ₁ = T ₀ ) is performed, one of the preset channels CHi (where i = 2 to n) for the youngest AM which is not yet selected is sequentially selected. Selected and corresponding reception frequency data FD (AM) i
Is read out and output to the AM / FM radio receiving unit 4,
Tune to the frequency indicated by D (AM) i (step S1)
7, YES in S170, NO in S18, NO in S19,
S16 is repeated). Reference time T ₁ in the first selection mode
If a key operation shorter than the reference time T ₁ is performed once with the unselected preset channel remaining in the AM channel, the system controller 2 performs the key operation shorter (n−1) times. Returns to the original standby mode (YES in step S17, NO in S170, YE in S18)
S, S10).

[0011] In the standby mode, if you want to channel calls for FM, the long key operation than the reference time T _0. Then, it is determined that FM channel calling is desired, and the second selection mode is set (Y in step S11).
ES, NO in S12, S20). In the second selection mode, the system controller 2A controls the AM / FM radio reception unit 4 to switch to the FM reception mode (step S21), and then selects among the second group of selection items registered in the channel memory 3. , The first one of the preset channels CH1 is selected, and the received frequency data FD (FM) 1 stored in association with the selected channel CH1 is read out.
The signal is output to the M / FM radio receiver 4 and tuned to the frequency indicated by the FD (FM) 1 (steps S22 and S23). In the second selection mode, each time the user performs a key operation on the key 1 once, the system controller 2A selects one of the preset channels CHi for the youngest FM not yet selected (where i = 2). To m) in order, and reads out the corresponding reception frequency data FD (FM) i,
The signal is output to the AM / FM radio receiver 4 and tuned to the frequency indicated by FD (FM) i (YES in step S24, S
NO at 25, S26 and S23 are repeated). In the second selection mode, the key operation is performed (m-1) times, and if there is no unselected preset channel in the FM channel, if the key operation is performed once more, the system controller 2A returns to the original. Returns to the standby mode (YE in step S24).
S, YES in S25, S10). In this way, the user can perform the key operation for one key 1 and
It is possible to perform any one of the channel calling operation for FM and the channel calling operation for FM.

If the user wants to call the FM channel, but accidentally operates the key 1 in the standby mode for a short time to enter the first selection mode, or in the first selection mode, for example, after you select the second preset channel CH2 for AM, such as when you wanted to channel calls for FM is carried out once the long key operation than the reference time T ₁ under the first selection mode. When the system controller 2A is a key operation is present longer than the reference time T ₁ under the first selection mode, step S1
7 and YES are determined in S170, the process proceeds to step S20, and immediately shifts to the second selection mode, and the AM / FM radio receiving unit 4 is controlled to switch to the FM reception mode (step S21). Of the second group of selection items registered in the preset channel CH1, which is the first one, is selected, and the reception frequency data FD (FM) 1 stored in association with the preset channel CH1 is read out.
The signal is output to the M / FM radio receiver 4 and tuned to the frequency indicated by the FD (FM) 1 (steps S22 and S23). Therefore, every time the user performs a key operation on key 1 once, the one for the youngest FM that has not been selected yet is selected.
Preset channels CHi (where i = 2 to m)
Are sequentially selected, and the corresponding reception frequency data FD (FM)
i, and outputs it to the AM / FM radio receiving unit 4,
Since tuning is performed to the frequency indicated by FD (FM) i, a desired preset channel for FM can be quickly selected (YES in step S24, NO in S25, S26, S
23 repeats).

According to this embodiment, if a key operation of the key 1 shorter than the reference time T ₀ is performed in the standby state, the AM preset channel selection mode can be set as the first selection mode. T ₁ sequentially it can invoke the preset channel for AM by repeating the shorter key operation, which as a standby state in the opposite relative key 1 as the second selection mode if a longer key operation than the reference time T ₀ The FM preset channel selection mode can be set, and thereafter, by repeating the key operation, the FM preset channels can be sequentially called. Moreover, when you are in the selected mode of preset channels for AM, when it want to select the preset channel for the FM, preset channel selection mode for FM if long a key operation than the reference time T ₁ , The desired channel can be selected immediately, and it is not necessary to repeat key operations until all channels are selected in the AM preset channel selection mode. Although T ₀ = 0.4 sec in the above-described embodiment, it may be 0.3 sec or 0.5 sec. Although T ₁ = T ₀ , T ₁ <T ₀ or T ₁ >
It may be T ₀ .

FIG. 3 is a flowchart showing a channel call reception control process of the system controller 2A according to a modification of FIG. 2. In FIG. 2, after the FM preset channel selection mode is set, the AM preset channel is selected. To shift to the channel selection mode,
The key operation was repeated in the selection mode of the preset channel for M, and after calling the last preset channel for FM, it was necessary to operate the key once more and return to the standby mode once. However, in the example of FIG. By performing a short key operation in the FM preset channel selection mode, it is possible to immediately shift to the AM preset channel selection mode. That is, in FIG. 3, the system controller 2A is a short key operation than the reference time T ₀ in a standby state, when the selected mode of the preset channel for AM, to exactly the same process as in FIG. 2 (3 Steps S10 to S17, S170, S18,
S19).

On the other hand, in the standby mode, if a key operation longer than the reference time T ₀ is performed to call the FM channel, the system controller 2A enters the second selection mode, and the AM / FM radio receiver 4 receives the FM reception mode. After switching control to (YES at step S11)
ES, NO in S12, S20, S21), the first one of the preset items CH1 among the second group of selection items registered in the channel memory 3, and selects the preset channel CH1.
Frequency data FD (FM) stored in association with
1 is read out and output to the AM / FM radio receiving unit 4,
Tune to the frequency indicated by FD (FM) 1 (step S
22, S23). In the second selection mode, the system controller 2A monitors the key operation time when a key operation is performed on the key 1, and thereafter, when the user operates the key 1
Each time a key operation longer than a predetermined third reference time T ₂ (however, T ₂ = T ₀ , but T ₂ > T ₀ or T ₂ <T ₀ is also possible) One of the preset channels CHi (where i = 2 to m) for the youngest FM not yet selected is selected in order, and the corresponding reception frequency data FD (FM) i is read out, and AM
/ FM radio receiver 4 and tune to the frequency indicated by FD (FM) i (YES in step S24, S24
0 is NO, S25 is NO, S26 and S23 are repeated). Perform second select a longer key operation than the third reference time T ₂ under mode (m-1) times, with the unselected preset channel runs out in for FM, further, once the third reference time system controller 2 if longer key operation than T ₂ is returns to the original standby mode (step S

0).

By the way, if the user wants to call the channel for AM, but accidentally operates the key 1 for a long time in the standby mode to enter the second selection mode, or if the user selects the FM in the second selection mode, for example, FM after you select the second preset channel CH2 of use, such as when you wanted to channel calls for the AM performs the third reference time T ₂ shorter than key operation once under the second selection mode. When the system controller 2A short key operation is present from the third reference time T ₂ under the second selection mode, step S
24 and S240 are determined to be YES, the process proceeds to step S13, and immediately shifts to the first selection mode, and the AM / FM radio receiver 4 is controlled to switch to the AM reception mode (step S14). From the first group of selection items registered in the memory, the first one, the preset channel CH1, is selected, and the reception frequency data FD (AM) 1 stored in association with the CH1 is read out, and the AM / Output to the FM radio receiving unit 4, FD (AM)
1 (steps S15 and S1).
6). Therefore, the rest is, every time a user is that once the short key operation than the reference time T ₁ for key 1, still one of the preset channel CHi for the youngest AM in that has not been selected (however, i = 2 To n) are sequentially selected, the corresponding reception frequency data FD (AM) i is read, and AM /
Since the signal is output to the FM radio receiver 4 and tuned to the frequency indicated by FD (AM) i, a desired AM preset channel can be quickly selected (YE in step S17).
S, NO in S170 and S18, and repetition of S19 and S16).

According to the example of FIG. 3, when the key 1 is operated for a shorter time than the predetermined first reference time T _{0 in} the standby state, the AM preset channel selection mode can be set as the first selection mode, later, it is possible to sequentially call the preset channels for AM by repeating the shorter key operation than a predetermined second reference time T _1, longer key than the first reference time T ₀ to the key 1 in the standby state the contrary if the operation can with a preset channel selection mode for FM as a second selection mode, since it is possible to sequentially call the preset channels for FM by repeating the longer key operation than a predetermined third reference time T ₂ . Moreover,
When you are in the selected mode of preset channels for AM, when it want to select the preset channel for the FM, preset channel selection mode for FM if the long key operation than the second reference time T ₁ , The desired channel can be selected immediately, and it is not necessary to repeat key operations until all channels are selected in the AM preset channel selection mode. Also, when you are in the selected mode of the preset channel for FM, when it want to select the preset channel for AM, the preset channel for AM if short keystrokes than the third reference time T ₂ Since the mode shifts to the selection mode, a desired channel can be selected immediately, and the trouble of repeating key operations until all channels are selected in the FM preset channel selection mode can be omitted. In FIG. 3, step S170
May be omitted, and if YES is obtained in step S17, the process may proceed to step S18.

FIG. 4 is a flowchart showing the channel call reception control processing of the system controller 2A according to another modification of FIG. 2. Hereinafter, the operation of another modification will be described with reference to FIG. By either Figure 2 in a standby state in key operation is longer or shorter than a predetermined reference time T ₀ first
Or switched to select mode has been switched or the second selection mode, the user as attempts to switch to the first selection mode for inexperienced (second selection mode), slightly below the slightly exceeds manipulate T ₀ (T ₀ Operation)
The mode switches to the selection mode. In the example of FIG. 4, in which erroneous operation was less likely to occur by disabled treat predetermined reference time T ₀ near the key operation.

In FIG. 4, the system controller 2A
Is set to the standby mode by the initial setting after the power is turned on (step S10). Then, the key signal input from the key 1 is checked, and if there is an H-level key signal input by pressing the key 1, it is determined that a key operation has been performed (Y in step S11).
ES) Then, the key operation time T, which is the duration of the key signal input at the H level (the key press duration), is monitored,
A predetermined first reference time T ₁ (for example, T ₁ = 0.3 sec)
When c) shorter key operation is the first selection mode is determined to the desired channel call for AM (YES in step S120, S13), the longer the predetermined than the first reference time T ₁ second reference time T ₂ (for example, T ₂ = 0.5
If a key operation longer than sec) is performed, it is determined that a channel call for FM is desired, and the second selection mode is set (YES in step S121, S20).

In the first selection mode, the system controller 2A controls the AM / FM radio receiver 4 to switch to the AM reception mode (step S1).
4) The first one of the first group of selection items registered in the channel memory 3, ie, the preset channel CH1
Is selected, the reception frequency data FD (AM) 1 stored in association with the CH1 is read out, output to the AM / FM radio receiver 4, and tuned to the frequency indicated by the FD (AM) 1 (step S15). , S16). Even after the first selection mode is entered, the system controller 2A monitors the key operation time when the key 1 is operated, and thereafter, the user operates the key 1 for a predetermined third reference time T
Each time a key operation shorter than ₃ (for example, T ₃ = T ₂ ) is performed, one preset channel CHi (where i = 2 to n) for the youngest AM that has not been selected is sequentially selected. Selected and corresponding reception frequency data FD (AM) i
Is read out and output to the AM / FM radio receiving unit 4,
Tune to the frequency indicated by D (AM) i (step S1)
7, YES in S171, NO in S18, NO in S19,
S16 is repeated). Shorter keystrokes than the third reference time T ₃ under the first selection mode is performed (n-1) times, with the unselected preset channel runs out in for AM,
Furthermore, once the third reference time T ₃ if shorter key operation is the system controller 2 returns to the original standby mode (NO in YES, S171 in step S17, S18
And YES, S10).

[0021] In the standby mode, if you want a channel call for FM, the longer key operation than the first reference time T predetermined second reference time T ₂ greater than _1. Then F
It is determined that the channel call for M is desired, and the second selection mode is set (YES in step S11, NO in S120, YES in S121, S20). In the second selection mode, the system controller 2A controls the AM / FM radio reception unit 4 to switch to the FM reception mode (step S21), and then selects among the second group of selection items registered in the channel memory 3. , The preset channel CH1, which is the first one, is selected, the reception frequency data FD (FM) 1 stored in association with the CH1 is read, and is output to the AM / FM radio receiving unit 4, and the FD (FM)
1 (steps S22 and S2).
3). Even in the second selection mode, each time the user performs a key operation on the key 1 once, the system controller 2A keeps one of the preset channels CHi (i. = 2 to m) in order, reads out the corresponding reception frequency data FD (FM) i, outputs it to the AM / FM radio reception unit 4,
Tune to the frequency indicated by (FM) i (step S24)
Is YES, S25 is NO, and S26 and S23 are repeated). In the second selection mode, the key operation is performed (m-1) times, and if there is no unselected preset channel in the FM channel, if the key operation is performed once more, the system controller 2A returns to the original. (YES in step S24, YES in S25, S10). In this manner, the user only needs to perform a key operation on one key 1 and the user can perform a channel calling operation for AM and an FM
It is possible to perform any channel calling operation among the channel calling operations.

By the way, if the user wants to call the channel for FM, but accidentally operates the key 1 for a short time in the standby mode, the mode is switched to the first selection mode. for example, when you select the second preset channel CH2 for AM, such as when you wanted to channel calls for FM is carried out the third reference time T 1 times longer than key operation ₃ under the first selection mode. The system controller 2A determines the long key operation is present from the third reference time T ₃ under the first selecting mode, YES in step S17 and S171, step S2
0, and immediately shifts to the second selection mode, where the AM / F
After controlling the M radio receiver 4 to switch to the FM reception mode (step S21), the first one of the second group selection items registered in the channel memory, the preset channel CH1, is selected. The reception frequency data FD (FM) 1 stored in association with the CH1 is read out, output to the AM / FM radio reception unit 4, and the FD (F
M) tuning to the frequency indicated by 1 (steps S22, S22)
23). Therefore, every time the user performs one key operation, one of the preset channels CHi (where i = 2 to m) for the youngest FM which has not been selected yet is selected in order, and the corresponding channel is selected. Received frequency data FD (FM) i
Is read out and output to the AM / FM radio receiving unit 4,
Since the frequency is tuned to the frequency indicated by D (FM) i, the desired F
A preset channel for M can be quickly selected (YES in step S24, NO in S25, S26, S23
Repeat).

According to the modification of FIG. 4, the key 1 is in the standby state.
Respect to the Select mode preset channels for AM as a first selection mode when a short key operation than a predetermined first reference time T ₁ is is longer predetermined than the first reference time T ₁ in the standby state from migrating to the selection mode of the preset channel for FM as the second selection mode when the long key operation than the second reference time T ₂ is longer second reference than the first reference time T ₁ of the at standby state Time T ₂
Since a shorter key operation is ignored, the possibility that the user makes an operation error and enters an undesired mode is reduced. Then, in the first selection mode, a predetermined third reference time T
By repeating key operations shorter than ₃ , the AM preset channels can be sequentially called, and by repeating the key operations in the second selection mode, the AM preset channels can be sequentially called. In addition, when in the AM preset channel selection mode, the FM
You want to select a preset channel for
Since the process proceeds to the third criteria selection mode preset channel for FM if a longer key operation from time T _3, immediately able to select the desired channel, the selection of all the channels in the selected mode under the preset channels for AM is This eliminates the need to repeat key operations until the end. In the example of FIG. 4, T ₁ = 0.3 sec.
sec or the like. In addition, although T ₂ = 0.5 sec, it may be 0.4 sec or 0.6 sec if T ₂ > T ₁ is satisfied. Furthermore, although T ₃ = T ₂ , T ₃ <T ₂ (such as T ₃ = T ₁ ) or T ₃ > T 2
₂ is good.

FIG. 5 is a flowchart showing a channel call reception control process of the system controller 2A according to the modification of FIG. 4. In FIG. 4, after the FM preset channel selection mode is set, the AM preset channel selection mode is started. To shift to the selection mode, it was necessary to repeat the key operation under the FM preset channel selection mode, call the last preset channel for FM once more, and then return to the standby mode once. However, in the example of FIG. 5, if a short key operation is performed in the preset channel selection mode for FM, the A
The mode can be shifted to the selection mode of the preset channel for M. That is, in FIG. 5, the system controller 2A is a short key operation than a predetermined first reference time T ₁ in the standby state, when the selected mode of the preset channel for AM, exactly the same process as in FIG. 4 (Steps S10 to S17, S171, S1 in FIG. 5)
8, S19).

On the other hand, in the standby mode, when the long key operation than the second reference time T ₂ to the channel calls for FM, the system controller 2A becomes the second selection mode, FM to AM / FM radio receiver 4 After controlling the switching to the reception mode (step S11)
YES at S120, NO at S120, YES at S121, S2
0, S21), of the second group of selection items registered in the channel memory 3, the first one of the preset channels CH1 is selected, and the reception frequency data FD (FM) stored in association with the CH1. 1 and read AM / F
The signal is output to the M radio receiving unit 4 and tuned to the frequency indicated by the FD (FM) 1 (steps S22 and S23). In the second selection mode, the system controller 2A monitors a key operation time when a key operation is performed on the key 1, and thereafter, when the user operates the key 1 for a predetermined fourth reference time T ₄ (for example, T _{4 4} = T ₁ Note that T ₄ is still selected each time a key operation longer than T ₄ <T ₁ or T ₄ > T ₁ (for example, T ₄ = T ₂ ) is performed once. One of the preset channels CHi (where i = 2 to m) for the youngest FM that is not selected, and reads out the corresponding reception frequency data FD (FM) i to read AM / FM
The frequency is output to the FM radio receiver 4 and tuned to the frequency indicated by FD (FM) i (YES in step S24, S241
Is NO, S25 is NO, S26 and S23 are repeated).
Performed a second selection mode under the fourth reference time T ₄ the longer the key operation (m-1) times, with the unselected preset channel runs out in for FM, further, once the fourth reference time system controller 2 if longer key operation than T ₄ has been is returned to the original standby mode (YES in YES, S241 in NO, S25 in step S24, S10).

If the user wants to call the channel for AM, but accidentally operates the key 1 for a long time in the standby mode to enter the second selection mode, or if the user selects the FM in the second selection mode, for example, the second after selecting the preset channel CH2 of use, such as when you wanted to channel calls for the AM performs fourth reference time T ₄ shorter than the key operation once under the second selection mode. When the system controller 2A short key operation is present than the fourth reference time T ₄ under the second selection mode, step S
24 and S241 are determined to be YES, the process proceeds to step S13, and immediately shifts to the first selection mode, and the AM / FM radio receiver 4 is controlled to switch to the AM reception mode (step S14). From the first group of selection items registered in the memory, the first one, the preset channel CH1, is selected, and the reception frequency data FD (AM) 1 stored in association with the CH1 is read out, and the AM / Output to the FM radio receiving unit 4, FD (AM)
1 (steps S15 and S1).
6). Therefore, every time the user performs a key operation on the key 1 once shorter than the third reference time T _3, one preset channel CHi for the youngest AM that has not been selected (i.e., i = 2 to n) in order, read out the corresponding reception frequency data FD (AM) i, and
Since the signal is output to the M / FM radio receiving unit 4 and tuned to the frequency indicated by FD (AM) i, a desired AM preset channel can be quickly selected (Y in step S17).
ES, NO in S171 and S18, repetition of S19 and S16).

According to the example shown in FIG. 5, when the key 1 is operated for a shorter time than the first reference time T _{1 in} the standby state, the AM preset channel selection mode can be set as the first selection mode. later, it is possible to sequentially call the preset channels for AM by repeating the shorter key operation than a predetermined third reference time T _3, which with the predetermined second reference time T ₂ to key 1 in the standby state to the opposite if a longer key operation can and preset channel selection mode for FM as the second selected mode, after sequentially calls it the preset channels for FM by repeating the longer key operation than a predetermined fourth reference time T ₄ Can be. Moreover, when you are in the selected mode of preset channels for AM, when it want to select the preset channel for the FM, the preset channel for the FM if the long key operation than the third reference time T ₃ Since the mode shifts to the selection mode, you can immediately select the desired channel,
This eliminates the need to repeat key operations until all channels are selected in the AM preset channel selection mode. Also, when you are in the selected mode of the preset channel for the FM, when it want to select the preset channel for AM, of preset channels for AM if the short key operation than the fourth reference time T ₄ Since the mode shifts to the selection mode, a desired channel can be selected immediately, and the trouble of repeating key operations until all channels are selected in the FM preset channel selection mode can be omitted. In FIG. 5, step S
171 may be omitted, and if YES is obtained in step S17, the process may proceed to step S18.
