Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in an audio device such as a car audio system equipped with a movable operation panel, and more specifically, the operation panel is returned to a predetermined position when the power is turned off. .
[0002]
[Prior art]
In the car audio system, an audio device such as a CD player is attached to a console portion between a driver's seat and a passenger seat, and a sound received from a radio or reproduced from a CD is played from a speaker in the vehicle. . As one type of such an audio device, a car audio system in which a movable operation panel is provided on the front surface of a main body and an insertion slot for a CD or the like appears when the operation panel is moved is known. The operation panel of this type of car audio system is called a slope panel or slope.
[0003]
FIG. 7 is a perspective view showing an example of this type of acoustic device. In this example, the main body 1 and the slope panel 2 attached to the front surface of the main body 1 are connected by a metal arm, a flexible printed wiring, etc., and various display units and operation switches are provided on the front surface of the slope panel 2. Is provided. Then, as shown in FIG. 8, when the slope panel 2 is moved so that the upper side is tilted toward the back while the lower side is protruded toward the front, an insertion port 8 such as a CD on the front surface of the main body appears. A recording medium such as a CD can be taken in and out.
[0004]
Here, the state in which the slope panel 2 covers the front surface of the main body 1 as shown in FIG. 7 is closed, and the state in which the slope panel 2 is inclined and the front surface of the main body 1 is visible as shown in FIG. Think. 9 to 11 are side views of the acoustic device shown in FIGS. 7 and 8 as viewed from the side. In other words, the slope panel 2 is normally closed during CD playback (FIG. 9) or at a desired angle that is easy for the user to see (FIG. 10). When a CD or the like is inserted or ejected (EJECT), the slope panel 2 is moved and opened automatically, manually, by a switch operation, etc., and the insertion slot 8 is exposed (FIG. 11). In such an acoustic device, since it is not necessary to provide both the operation unit and the insertion port on the front surface of the main body, the main body can be thinned.
[0005]
[Problems to be solved by the invention]
Such a slope panel can be adjusted by the user by hand, and can also be moved from the main unit side by a drive motor if necessary, but the car audio system including the sound device can be turned on and off. When it comes to, there was the following problem regarding how to control the slope panel. The power source of the car audio system can be turned on or off in conjunction with the on / off of the accessory power source (ACC) controlled by the ignition key of the car.
[0006]
First of all, it can be considered that the slope panel is not operated even when the power is turned off. However, in this case, if the power is turned off while the slope panel is open, such as after ejection of a CD, the slope panel remains open. For this reason, there is a possibility that an object or the like hits the open slope panel and the slope panel or the object is damaged. In addition, since the slope panel remains open when the power is turned on next time, the user has to adjust the slope panel to an appropriate angle so that the slope panel can be easily seen.
[0007]
As another example, when the power is turned off, the slope panel can be closed to the fully closed position. In this case, even if the power is turned off with the slope panel open after ejecting the CD, the slope panel closes to the fully closed position, so there is no risk of damage by hitting the slope panel. . However, the next time the power is turned on, the user must again adjust the angle with respect to the closed slope panel.
[0008]
As yet another example, it is conceivable that the user can set an easy-to-see slope panel position in the main body in advance. Such a preset position is called a memory position. In this case, conventionally, when the power is turned off, the slope panel is closed to the fully closed position, and when the power is turned on next time, the slope panel is returned to the memory position.
[0009]
In this example, even if the power is turned off while the slope panel is open, such as after ejecting a CD, the slope panel closes to the fully closed position, so there is no risk of damage by hitting the slope panel. . Further, when the power is turned on next time, the closed slope panel opens to the memory position, so that the user does not need to adjust the angle again. However, in such a case, when the power is turned on, there is a problem that the display is difficult to see and the operation is difficult until the slope panel opens to the memory position.
[0010]
The present invention has been proposed to solve the above-described problems of the prior art, and its purpose is to return the slope panel to a predesignated position when the power is turned off and display it when the power is turned on. It is to make it easy to see.
[0011]
[Means for Solving the Problems]

And the memory position is set by the user selecting a predetermined angle that does not fully close the operation panel .
The invention of claim 3 grasps the invention of claim 1 from the viewpoint of the method, and in the control method of the movable operation panel provided in the acoustic device, the desired position of the operation panel is set in advance as the memory position.

According to the first and third aspects of the present invention, if a position where the operation panel is easy to see and does not interfere is set in advance as the memory position, the operation panel moves to this memory position when the power is turned off. For this reason, while the power is off, the operation panel does not make a big business trip and does not get in the way. Further, when the power is turned on next time, the operation panel is already in the memory position, so that the display can be easily seen without waiting to move to the memory position.
[0012]

It is used to construct a car audio system by connecting to an accessory power source, an antenna terminal, an in-vehicle speaker, etc. (not shown).
[0015]
[1-1. Mechanical structure)
First, FIG. 1 is a side view conceptually showing how the slope panel is attached to the front surface of the main body and driven in the present embodiment. That is, the main body 1 and the slope panel 2 are connected by the first arm 3 and the second arm 4. Among these, the first arm 3 is a plate-like member, and there is one pair at each of the left and right ends when the main body 1 is viewed from the front, and both ends of the first arm 3 are arranged as shown in FIG. Is attached to the upper part of the main body 1 and the other is attached to the upper part of the slope panel 2 so as to be rotatable.
[0016]

As shown in FIG. 1, the second arm 4 is a plate-like member roughly shaped like a "<", and has three joints J1, J2, and J3 (connection portions), of which the center The joint J2 is rotatably attached to the lower part of the main body 1. Further, the joint J1 on the left side in FIG. 1 is rotatably attached around the center of the slope panel 2 in the vertical direction. Further, the joint J3 on the right side of FIG. 1 is an elongated hole.
[0017]
On the other hand, a driving disk 5 is provided inside the main body 1 as a driving member for indirectly moving the slope panel 2 via a motor. That is, the driving disk 5 is configured to rotate left and right by a slope driving motor (not shown), and the pin P standing on the surface of the driving disk 5 is in the joint J3 of the second arm 4. It is inserted so that it can slide freely.
[0018]
Further, the present embodiment is configured to indirectly determine whether or not the slope panel 2 is in a preset memory position via the driving disk 5. That is, the drive disk 5 is provided with a member 6 indicating a memory position. This member 6 is a protrusion that can be freely moved and fixed to a desired position on the circumference of the drive disk 5. Such a member 6 may be configured to be moved to a desired position on the circumference of the driving disk 5 by a thin motor provided on the driving disk 5, for example.
[0019]
The main body 1 is provided with a memory position detection switch 7 for detecting a memory position by detecting the member 6. That is, when the slope panel 2 is at a desired position, that is, the memory position, if the member 6 on the driving disk 5 is moved to the position detected by the memory position detection switch 7, then the slope panel 2 is moved to the memory position. At this time, the memory position detection switch 7 detects the member 6.
[0020]
[1-2. Configuration of control circuit)
FIG. 2 shows the configuration of a control circuit that controls the present embodiment. That is, this control circuit is not shown in FIG. 1, but the control microcomputer 91 includes the memory position detection switch 7 shown in FIG. 1, the KEY matrix 92 that receives key inputs, and the slope drive motor 93. Are connected to the ACC switch 95.
[0021]
Among them, the KEY matrix 92 is selected from various operation keys including an OPEN key for fully opening the slope panel 2, a CLOSE key for fully closing the slope panel 2, and a memory position key for setting a memory position. This is to detect a key pressed by the user. Specifically, it uses a matrix-like contact group of flexible printed wiring provided on the back side of the operation key group. The microcomputer 91 controls the movement of the slope panel 2 when these keys are pressed or ACC is turned off.
[0022]
Further, the slope driving motor 93 opens and closes the slope panel 2 by rotating the driving disk 5 shown in FIG. 1 by a desired angle to the left and right and moving the second arm 4 with the pin P of the driving disk 5. It is a motor for making it. The ACC switch 95 is a means for detecting that the accessory power supply (ACC) of the automobile that is the power supply of the acoustic device of the present embodiment is turned off (hereinafter referred to as “ACC OFF”).
[0023]
[1-3. (Configuration of microcomputer)
The functions performed by the microcomputer 91 shown in FIG. 2 are shown in the functional block diagram of FIG. The configuration shown in FIG. 3 is realized by controlling the microcomputer 91 with software such as an embedded program. The specific mode is to use either an assembler or a compiler, and the software is recorded on a ROM chip. There are various possibilities such as whether to execute the program after reading it from a recording medium such as a CD-ROM. Therefore, in FIG. 3, functions performed by the microcomputer 91 will be described using virtual circuit blocks.
[0024]
That is, the microcomputer 91 includes means 911 for opening and closing the slope, means 912 for setting the memory position, means 913 for detecting ACC OFF, means 914 for determining the movement of the slope, means 915 for controlling the motor, Means 916 for detecting the memory location.
[0025]
Among these, the means 911 for opening and closing the slope is a means for opening and closing the slope in response to pressing of the OPEN key or the CLOSE key, and the position of the slope is stored as information 917 of the slope position. The memory position setting means 912 is a means for setting a desired position of the slope panel 2 as a memory position using a memory position key.
[0026]
A means 913 for detecting ACC OFF is a means for detecting via the ACC switch 95 that the accessory power supply (ACC) of the automobile has been turned off. Further, the means 914 for determining the movement of the slope is a means for determining how the slope is moved when ACC OFF is detected. Specifically, the slope panel 2 is stored in the memory when ACC OFF is detected. When not in position, the slope panel 2 is moved to the memory position by moving the slope driving motor 93 via the motor control means 915.
[0027]
The motor control means 915 is a means for moving the slope panel 2 by controlling the slope driving motor 93. The memory position detecting unit 916 is a unit that determines whether the slope panel 2 is at a preset memory position by using the memory position detecting switch 7.
[0028]
The member 6 indicating the memory position, the memory position detection switch 7, and the means 916 for detecting the memory position constitute “determining means” in the claims. Further, the means 914 for determining the movement of the slope, the means 915 for controlling the motor, the slope driving motor 93 and the driving disk 5 constitute the “moving means” in the claims.
[0029]
[2. Action and effect)
This embodiment as described above has the following operation.
[2-1. (Normal opening / closing operation)
First, when the user presses the OPEN key or the CLOSE key while the accessory power supply (ACC) is on, the means 911 for opening and closing the slope sends a signal to the means 915 for controlling the motor, and the slope driving motor 93 By driving, the slope panel 2 is moved to the fully open or fully closed position. Further, when it is necessary to move the slope panel 2 for CD ejection or the like, the slope panel 2 is similarly moved, and the current position of the slope panel 2 is stored as the slope position information 917. Is done.
[0030]
When the slope driving motor 93 rotates the driving disk 5 in this way, for example, if the driving disk 5 rotates counterclockwise from the state of FIG. 4, the pin P standing on the surface of the driving disk 5 However, the joint J3 portion of the second arm 4 is pushed down. As a result, the second arm 4 raises the slope panel 2 upward with the joint J2 as a fulcrum, and the slope panel 2 moves toward the fully closed state shown in FIG.
[0031]
On the other hand, for example, if the driving disk 5 rotates clockwise from the state of FIG. 4, the pin P standing on the surface of the driving disk 5 pushes up the joint J3 portion of the second arm 4 upward. . As a result, the second arm 4 uses the joint J2 as a fulcrum and the joint J1 pushes the slope panel 2 downward, and the slope panel 2 moves to the fully open state shown in FIG.
[0032]
[2-2. (Memory location setting)
In addition, the user selects an angle at which the display is most easy to see for the slope panel 2 and sets this angle (position) as a memory position. For example, while the memory position key is pressed, the slope panel 2 slowly reciprocates from the fully open position to the fully closed position, and when the desired angle is reached (for example, FIG. 10), when the memory position key is released, The slope panel 2 stops, and at the same time, the means 912 for setting the memory position fixes the member 6 indicating the memory position to the position of the memory position detection switch 7 (FIG. 4).
[0033]
In this way, when the driving disk 5 is rotated next and the slope panel 2 comes to the memory position again, the memory position detecting means 916 detects this by using the memory position detecting switch 7. Can do. The memory location may be selected from a plurality of candidates by key operation. When the memory location is set in this way, the fact that the memory location is set is recorded as memory location information 918.
[0034]
[2-3. Processing when ACC is OFF]
FIG. 5 shows a processing procedure when the ACC is turned off with the memory position set as described above. That is, when ACC OFF is detected, the processing shown in the flowchart of FIG. 5 is started. First, the means 914 for determining the slope movement refers to the slope position information 917 and the memory position is detected from the means 916 for detecting the memory position. By receiving the state of the position detection switch 7, the position of the slope panel 2 at that time is determined (step 1).
[0035]
At this time, for example, if the slope panel 2 is already at the memory position (FIG. 10), the member 6 indicating the memory position pushes the memory position detection switch 7 (FIG. 4), and this means that the memory position is detected. 916 reports to the means 914 for determining the slope movement. In this case, the sound device may be turned off without performing any operation.
[0036]
On the other hand, if the slope deciding means 914 refers to the slope position information 917 and the slope panel 2 is in the fully open position (OPEN position) (FIGS. 11 and 6), the slope movement The means for determining 914 causes the means for controlling the motor 915 to start the operation of the slope driving motor 93 in the CLOSE direction (step 2).
[0037]
Conversely, when the means 914 for determining the slope movement refers to the slope position information 917, the slope panel 2 is found to be in the fully closed position (CLOSE position) (FIGS. 9 and 1). The means 914 for determining the movement of the slope causes the means 915 for controlling the motor to start the operation of the slope driving motor 93 in the OPEN direction (step 3).
[0038]
When the slope driving motor 93 starts operating in this manner, the memory position detecting means 916 monitors the memory position detecting switch 7 by repeatedly determining the state of the memory position detecting switch 7 (step 4). As a result of the rotation of the driving disk 5, when the slope panel 2 reaches the memory position set by the user, the member 6 indicating the memory position pushes the memory position detection switch 7. Then, the means 916 for detecting the memory position detects this (step 4), and the means 914 for determining the movement of the slope causes the means 915 for controlling the motor to stop the slope driving motor 93 (step 5).
[0039]
As a result of the above processing, when the ACC is OFF, the slope panel 2 always returns to the memory position and stops. For this reason, even if, for example, the ACC is turned off while the slope panel 2 is open, the slope panel 2 is automatically closed to the memory position.
[0040]
[2-4. effect〕
As described above, in the present embodiment, if the position where the slope panel 2, that is, the operation panel is easy to see and is not obstructed is set in advance as the memory position, the operation panel moves to this memory position when the power is turned off. For this reason, while the power is off, the operation panel does not make a big business trip and does not get in the way. Further, when the power is turned on next time, the operation panel is already in the memory position, so that the display can be easily seen without waiting to move to the memory position.
[0041]
In particular, in this embodiment, since the position of the operation panel is indirectly determined from the position and angle of the driving member, no sensor or the like is required around the operation panel, and the configuration is simplified.
[0042]
[3. Other Embodiments]
In addition, this invention is not limited to the said embodiment, Other embodiments which are illustrated next are included. For example, in the above embodiment, only one memory position detection switch is shown to simplify the description, but a plurality of memory position detection switches may be provided. As a specific example, a memory position detection switch is provided for each different position of the slope panel, and the memory position is set according to which switch is pressed by a projection provided on the drive disk side, or the slope panel is set to the memory position. It is also possible to determine whether or not Further, the position of the slope panel may be detected using, for example, a linear position sensor instead of using a switch. Further, the memory position may be determined by omitting the memory position detection switch and monitoring the driving time of the motor.
[0043]
【The invention's effect】
As described above, according to the present invention, by returning the slope panel to a predetermined position when the power is turned off, the display becomes easier to see when the power is turned on, and the usability of the acoustic device is improved.
