Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an operating device for equipment used in, for example, in-vehicle audio equipment and household electronic equipment. More specifically, for example, switches that are rarely used are used in equipment. Main operation panel (hereinafter,
In addition to the main panel), it is placed on a movable sub-operation panel (hereinafter referred to as the sub-panel) that can be retracted from the main body of the device, and prevent damage to the body or the sub-panel itself due to the open state of the sub-panel. It is what

Further, the present invention naturally includes not only the sub-panel but also a device operating device in which the main panel itself having many main switches is movable as a field of use.

[Prior Art] In order to make an audio device multi-functional, it is necessary to increase the number of switches for controlling the functions, but the operation panel area of the audio device is naturally limited, and Since miniaturizing and integrating the switches to fit all the switches in a limited space deteriorates operability,
The area of the operation panel limits the number of switches arranged on the operation panel and thus the function.

This tendency is particularly noticeable in vehicle-mounted audio equipment in which the operation panel area is extremely small due to restrictions on the installation location.

In order to meet such demands for multi-functionality, a sub-panel that can be freely retracted and retracted is provided on the main panel, and switches that are used less frequently are placed on this sub-panel, and the open / close switches provided on the main panel are used to operate the motor. There is conventionally known a device that automatically opens and closes the sub panel by opening and closing the sub panel and detecting that the sub panel is not housed when the power switch is turned off, even though the power switch is off.

FIG. 3 is an external view showing an example of an audio device having such a configuration, in which a main panel 52 of the audio device main body 51 is provided with a sub-panel portion 53 movable between an operation position and a storage position,
A sub-panel 59 in which switches 60 are arranged is formed in the portion which is concealed when stored. FIG. 3 a) shows the sub-panel portion 53 moving in the front-back direction, and b) shows the sub-panel portion 53.
Is rotated about its one side surface as a fulcrum, and c) is a sectional view d), and as is clear from the sectional view d, the sub-panel portion 53 formed in a polygonal column is rotated about its central axis as a fulcrum, and the operation position is the main position. It is set on substantially the same plane as the surface of the panel 52.

FIG. 4 is a circuit block diagram of the prior art used in FIG. 3 a), except for the part excluding the sub-panel part moving mechanism,
Common to the examples of b) and c) d).

In FIG. 4, reference numeral 56 is a main power supply circuit and 57 is an auxiliary power supply circuit.
57 rises, and then power is supplied to the main power supply circuit 56. Reference numeral 58 denotes an audio circuit, the function of which is controlled by a switch arranged on the main operation panel and a switch group 60 on the sub panel 59 provided at a position hidden when the sub panel portion 53 is stored.

A rack 61 is provided on a part of the side surface of the sub-panel portion 53, and by engaging with a pinion 62 that is rotated by a motor 63, the sub-panel portion 53 is moved in and out according to the forward / reverse rotation of the motor 63. . 64 and 65 are sub-panel parts 53, respectively
This is a switch that turns on when is in the open position or storage position.

When the drive circuit 66 receives the ON signal of the sub panel opening / closing switch 55 and the storage state signal that the state detection circuit 67 detects and outputs the state of the switch 65, the drive circuit 66 sends a motor 63 forward rotation command to open the sub panel unit 53. Let go switch 64
Is turned on to detect that the sub-panel portion 53 has moved to a predetermined open position, and a stop signal is output to the motor 63.

On the other hand, when the switch 65 is off and the state detection circuit 67 does not output the stored state, the sub panel open / close switch 55
When the ON signal of is input, the motor reverse rotation command is sent to the motor 63, and when the sub panel 53 reaches the predetermined storage position and the switch 65 is turned on, the output of the state detection circuit 67 is received and the motor stop signal is output. To do.

In the above configuration, when the power switch 54 is turned off,
The power supply from the auxiliary power circuit 57 to the main power circuit 56 is cut off, but the auxiliary power switch controlled by the state detection circuit 67
Since 68 is still in the ON state, the auxiliary power supply circuit 57 and the sub-panel section opening / closing circuits (66, 67, etc.) continue to be supplied with power.

If the state detection circuit 67 detects that the power supply from the main power supply circuit 56 has become zero, that is, when the power switch 54 is off, and the switch 65 is in the on state, the state detection circuit 67 turns off the auxiliary power switch 68. Power off the audio device completely. However, when the power switch 54 is turned off and the switch 65 is also turned off, that is, when it is detected that the sub-panel portion 53 is not in the housed state, the drive circuit 66 is caused to output a motor reverse rotation command. When the switch 65 is detected to be on, the drive circuit 66 is caused to output a motor stop command and the auxiliary power switch 68 is turned off.

[Problems to be Solved by the Present Invention] As described above, in the related art, it is possible to automatically move the sub panel to the storage position by detecting that the sub panel is not in the storage position when the power switch is turned off. ,
If the switch 65 malfunctions due to deterioration over time, etc., the status detection circuit 67 detects the closed status even though the sub panel is actually open, and the sub panel remains open even after the power switch is turned off. An object of the present invention, which is left as it is, is to provide an equipment operating device capable of surely accommodating an operation panel based on the state of a power source.

[Structure of the Invention] (Means for Solving Problems) The device of the present invention has an operating means and is provided in the main body of the device.
An operation panel that can be displaced between the operation position and the storage position,
Driving means for driving the operation panel to move the operation panel between the operation position and the storage position, a voltage detection circuit for detecting a drop in the power supply voltage to the equipment body, and an output of the voltage detection circuit. And a control means for driving the drive means in the storage direction of the operation panel for a certain period of time.

(Operation) When the power supply voltage supplied to the device body drops, the control means operates to drive the sub-panel toward the storage position for a certain period of time.

(Embodiment) An embodiment of the present invention will be specifically described below with reference to the drawings. The same components as those shown in FIG. 4 are designated by the same reference numerals and the description thereof will be omitted.

FIG. 1 is a block diagram of an embodiment of the present invention, in which 1 is a control microcomputer, 2 is a timer connected to the control microcomputer 1, and 3 is a voltage that outputs an output signal when the voltage of the main power supply circuit 4 falls below a certain value. The detection circuit 5 is an auxiliary power supply circuit that supplies power from the preceding stage of the power switch 54 and always energizes the control microcomputer 1.

FIG. 2 is a flowchart showing the flow of operation of the control microcomputer 1 of FIG.

In FIG. 1, if the power switch 54 is off,
The sub-panel portion 53 is always stored. Even if the opening switch 55 is operated in this state, the control microcomputer 1 does not command the sub-panel opening operation.

When the power switch 54 is turned on, the control microcomputer 1 receives power from the main power supply circuit 4,
The operation shifts to the open switch 55.

Then, when the opening switch 55 is operated, the control microcomputer 1 detects the ON signal of the position detection switch 65 provided at the storage position of the sub-panel portion 53, commands the motor 63 to rotate normally, and controls the sub-panel portion 53. Move to the operating position.
When the sub panel 53 reaches the operating position, the position detection switch 64
When is turned on, the control microcomputer 1 receives this and the motor 63
The stop command is output to. When the open / close switch 55 is operated again, the control microcomputer 1 detects the off state of the position detection switch 65 and commands the motor 63 to rotate in the reverse direction.
Move toward the storage position. When the sub-panel portion 53 reaches the storage position and the position detection switch 65 is turned on, the control microcomputer 1 outputs a stop command to the motor 63.

When the power switch 54 is turned off, the output voltage of the main power circuit 4 drops rapidly. The voltage detection circuit 3 sends an output signal to the control microcomputer 1 when the output voltage becomes a certain value or less. In response to this, the control microcomputer 1 resets the timer 2, starts counting, and commands the motor 63 to rotate in the reverse direction. When the timer 2 reaches a predetermined value, the control microcomputer 1
Sends a stop command to the motor 63. Although the predetermined value of the timer 2 is set to 2 seconds in FIG. 2, it is not limited to this, and it is sufficient time for the sub-panel portion 53 to move from the open position to the storage position by the reverse rotation of the motor 63. I wish I had it.

In each of the above-described embodiments, the configuration in which the sub-panel is moved by the engagement of the pinion and the rack has been described, but the present invention is not limited to this.

Further, the configuration is not limited to the configuration in which the sub-panel is moved back and forth, and various configurations including the configuration illustrated in FIGS. 3B to 3D can be adopted.

Further, in the above description, an example in which a sub panel is provided in a part of the main panel has been described, but the present invention does not include a part different from the main panel of the device main body, for example, a side panel provided with a sub panel or the main panel itself. Needless to say, it also includes a device that is movable and has switches on the back surface.

[Advantages of the Invention] As described above, according to the device of the invention, even if a switch or the like for detecting the position of the operation panel causes a malfunction, the operation panel is forcibly driven toward the storage position for a certain period of time. Therefore, the operation panel can be reliably moved to the storage position.

In addition, it is possible to simplify the circuit configuration of the device.
