Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mode setting method for setting a plurality of modes using, for example, switches.

[0002]

2. Description of the Related Art FIG. 2 shows a configuration example of a conventional channel setting circuit. This conventional example uses GROUP settings and SYSTEM
This is an example of a wireless device that performs two types of channel settings depending on the settings. In FIG. 2, the display device 1 is a display device corresponding to the GROUP mode, and the display device 2 is a display device corresponding to the SYSTEM mode.
Each has an independent display function. In addition, corresponding to each of the above modes, it has a GROUP setting push button switch 6 and a SYSTEM setting push button switch 7. To change the number of channels displayed on the display 1, the GROUP setting push button switch By pressing 6, the signal is given to the microcomputer 5, and the number of channels displayed on the display 1 is increased by the processing of the microcomputer 5. Similarly, to change the number of channels displayed on the display unit 2, SY
The STEM setting push button switch 7 is pressed to give the signal to the microcomputer 5, and the number of channels displayed on the display 2 is increased by the processing of the microcomputer 5.

[0003]

As described above, in the prior art, since each switch has an independent switch for changing a plurality of modes, the number of switches is required to be the number of modes, and the cost is reduced. It had the drawback of not being suitable for downsizing and weight reduction. In view of the above situation, it is an object of the present invention to provide a mode setting method capable of setting a plurality of modes with one switch.

[0004]

In order to achieve the above-mentioned object, the present invention makes one rotary switch correspond to a plurality of modes and switches a plurality of modes in accordance with the reciprocating operation of the rotary switch. It is a thing.

[0005]

As a result, with one rotary switch,
Multiple modes can be set, and cost reduction, size reduction, and weight reduction can be achieved.

An embodiment of the present invention will be described below with reference to FIG. In this embodiment, GROUP setting and SYSTEM
This is an example of a wireless device that sets two channels by setting. In FIG. 1, the display unit 1 is a display unit compatible with the GROUP mode and the display unit 2 is compatible with the SYSTEM mode, and they have independent display functions. Usually GRO
In the UP mode, when the rotary switch 4 is rotated, the switching signal is given to the microcomputer 3, and the number of channels displayed on the display 1 is changed by the processing of the microcomputer 3. In the present embodiment, when the rotary switch 4 is rotated, the number of display changes by 3 counts or more, and the number of channel display returns by 3 counts or more. If the rotation operation is performed within 2 seconds, the microcomputer 3 changes this. The detection and setting mode is switched to the SYSTEM mode, and the SYSTEM setting becomes possible. In order to return to the GROUP setting mode after setting SYSTEM, the operation that the number of displayed channels changes by 3 counts or more when the rotary switch 4 is rotated and the number of displayed channels returns by 3 counts or more within 2 seconds. You can do it again. If the rotary switch 8 is not rotated for 10 seconds or more, the GROUP setting mode is restored.

This embodiment will be described in detail with reference to the flowchart of FIG. First, display A (GROUP)
The state of is stored in the microcomputer 5 (step S1), the number of channels displayed on the display A is adjusted according to the rotation direction of the rotary switch 4, and it is determined whether or not there is a change of 3 counts or more (step S2). If the decision result in the step S2 is YES, it is decided whether or not the time from the step S1 has passed a prescribed time (1 second) or more (step S3). If the decision result in the step S3 is NO, the rotary switch is rotated in the opposite direction of the step S1 to decide whether or not the channel display number of the display A changes by 3 counts or more (step S4).
If the determination result of step S4 is YES, step S1
It is determined whether the time from is within a specified time (2 seconds) (step S5). Here, step S2 is NO, step S3 is YES, step S4 is NO, step S5
If the determination result is NO, the process returns to step S1. Next, if the decision result in the step S5 is YES, the mode is changed (step S6), and the display B (SYST) is displayed.
The microcomputer 5 stores the state of EM) (step S
7). Then, it is judged whether or not there is any input within the specified time (10 seconds) from step S7 (step S7).
8), if YES, return to step S1. Step S8
If the result of the determination is NO, the number of channels displayed on display B is adjusted according to the direction of rotation of the rotary switch 4, and display B changes to 3
It is determined whether or not there is a change of more than the count (step S
9). When the result of the determination in step S9 is YES, it is determined whether the time from step S7 has exceeded the specified time (1 second) or more (step S10). If the decision result in the step S10 is NO, the rotary switch is rotated in the opposite direction to the step S9, and it is decided whether or not the channel display number of the display B changes by 3 counts or more (step S11). When the result of the determination in step S11 is YES, it is determined whether or not the time from step S7 is within the specified time (2 seconds) (step S12). Here, if the determination result of step S10 is YES, step S11 is NO, and step S12 is NO, the process returns to step S7. If the determination result in step S12 is YES, the process returns to S1. In the above embodiment, the case where the number of modes is 2 has been described, but the present invention is not limited to this.
Obviously, by providing a plurality of types of the specified time, it is possible to apply to the mode setting of three modes or more.

[0008]

As described above, according to the present invention, it is possible to set a plurality of modes by using only one switch without adding any other switch, so that the cost can be reduced, the size can be reduced, and the weight can be reduced. In addition to the above, the remarkable effect that the operability is improved is obtained.
