Description

[0001]
[Industrial applications]
The present invention relates to an on-vehicle acoustic device having a movable operation surface such as a car stereo.
[0002]
[Prior art]
For example, a recent in-vehicle acoustic device such as a car stereo is provided with a movable operation surface as a front movable panel, and the movable operation surface is provided with an opening / closing mechanism for controlling the opening / closing operation by a motor. I have. When the car stereo is used, the movable operation surface is moved by the opening / closing mechanism to be in an open state, so that a cassette tape can be inserted and various buttons can be operated. On the other hand, except when the car stereo is used, the movable operation surface is closed by the opening and closing mechanism. Here, in the open state of the movable operation surface when using the car stereo, in consideration of the possibility that the occupant may come into contact with the movable operation surface due to the recoil in the event of a collision accident, etc. The surface is made of a material that is easily damaged by contact.
[0003]
Also, in some countries, there is a standard that the vehicle interior must not have sharp projections, so that the movable operation surface must be open for a certain period of time to avoid exposing projections such as operation buttons. Then, the movable operation surface may be forcibly closed. However, if the movable operation surface is forcibly closed after a certain period of time, an obstruction such as a cassette tape may be present in the insertion opening serving as a movement trajectory of the movable operation surface when the movable operation surface is closed. If this happens, this obstacle will be involved. This not only makes it difficult to securely close, but also causes the movable operation surface or its opening mechanism to break down.Therefore, the occupant checks the existence of obstacles and closes the movable operation surface as much as possible. Must be kept. Thus, protection of the movable operation surface and safety of the occupant are achieved.
[0004]
[Problems to be solved by the invention]
By the way, the following problems exist in the in-vehicle acoustic device having a movable operation surface like a conventional car stereo.
(1) Since the movable operation surface including the opening / closing mechanism is made of a material which is easily damaged from a safety point of view, even in a normal use other than during an accident, the movable operation surface is erroneously operated with the movable operation surface open. In the case of contact with the surface, it is easy to break. For this reason, damage due to unnecessary causes increases.
(2) Since the occupant is required to frequently perform the operation of closing the movable operation surface, a complicated operation is required. Along with this, a hindrance to safe driving will occur.
[0005]
The present invention has been made in view of the above-described problems, and has a movable operation surface having a movable operation surface that prevents damage to the movable operation surface due to unnecessary causes and eliminates a complicated operation imposed on an occupant. It is intended to provide a device.

A third means for detecting whether or not a recording medium is present in the movable operation surface, and driving the movable operation surface to be closed when it is determined that there is no recording medium in the insertion port in the open state of the movable operation surface. A fourth means, and a fifth means for controlling the time from when it is determined that the recording medium is not present to when the movable operation surface is closed to be different based on the detection result of the first means. Which is characterized by having
[0007]
[Action]
According to the configuration of the present invention, when it is determined that there is no recording medium in the insertion opening of the movable operation surface in the open state of the movable operation surface, the movable operation surface is driven to be closed. . At this time, control is performed so that the time from when it is determined that the recording medium is not present to when the movable operation surface is closed is made different based on the result of the detection of power on / off. As a result, the movable operation surface is closed after the required minimum time has elapsed, so that the movable operation surface can be prevented from being damaged due to unnecessary causes, and a complicated operation imposed on the occupant can be eliminated.
[0008]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of a vehicle-mounted acoustic device having a movable operation surface according to the present invention. Reference numeral 1 denotes a power supply which is composed of a battery and is used as a main power supply (power supply), an ACC power supply, and the like to operate various on-vehicle acoustic devices including a car stereo. Reference numeral 2 denotes a power supply state detecting means (first means) for detecting on / off of the power supply 1, 3 means for detecting an open state of the movable operation surface (second means), and 4 a cassette tape at an insertion opening of the movable operation surface. (Third means) for detecting whether or not there is a recording medium as described above. Reference numeral 5 denotes a means (fourth means) for driving the movable operation surface to be closed when it is determined that there is no recording medium in the insertion opening of the movable operation surface in the open state of the movable operation surface, as described later. Numeral 6 makes the time from when it is determined that there is no recording medium in the insertion slot of the movable operation surface to when the movable operation surface is closed based on the detection result of the power supply state detection means 2 described later. (Fifth means).
[0009]
The control means 6 is constituted by a microcomputer, and performs necessary control operations by inputting detection signals from the means 2, 3, 4, and 5. Reference numeral 7 denotes a movable operation surface opening time setting timer that can arbitrarily set the opening time of the movable operation surface built in the control unit 6. This setting timer 7 is used, as described later, when it is determined that there is no recording medium in the insertion opening of the movable operation surface when the power supply state detection unit 2 detects the ON state in the open state of the movable operation surface. In addition, a certain period of time is provided from the determined time to the time when the movable operation surface is closed. That is, the setting timer 7 is provided to secure the time necessary for the replacement operation on the assumption that the cassette tape is replaced when the power is on and the movable operation surface is open. ing.
[0010]
The control unit 6 includes a logic unit for detecting and controlling the power supply state, a logic unit for detecting and controlling the open state of the movable operation surface, a logic unit for detecting and controlling the presence or absence of a recording medium in the insertion slot, and a movable operation surface. And a logic unit for activating the means 5 for driving the opening and closing of the unit, a logic unit for counting (measuring) and controlling the time set by the setting timer 7, and the like. The control means 6 has a built-in means for measuring the opening time of the movable operation surface based on the detection signal from the detecting means 3, and the time set by the setting timer 7 by the time measuring means. When is counted to the end, the controlling means 6 controls the driving means 5 to close the movable operation surface.
[0011]
Next, the operation of this embodiment will be described with reference to the flowchart of FIG.
As an example, an example in which a cassette tape is inserted into a car stereo will be described. The opening time of the movable operation surface is arbitrarily set in advance by the movable operation surface opening time setting timer 7. First, in step A, it is determined whether or not a power supply, for example, a power supply is on. If the power supply is on, the flow proceeds to step I. If it is off, the flow proceeds to step B. In step B, it is determined whether or not a cassette tape has been inserted into the car stereo. If not, the flow proceeds to the end of the subsequent stage of step H, and the operation ends. This is because if there is no cassette tape in the car stereo, the movable operation surface is opened and playback is not possible even after loading the cassette tape, so the operation of closing the movable operation surface is ignored. That is because If a cassette tape has been inserted, the flow proceeds to step C, where the movable operation surface is opened. Subsequently, after the cassette tape is ejected in step D, the flow proceeds to step E, where it is determined whether or not a cassette tape is present in the insertion port of the movable operation surface. If not, the flow proceeds to step H, where the movable operation surface is closed. If yes, repeat until no.
[0012]
On the other hand, if the ACC power is on, the flow proceeds to step I, where it is determined whether or not a cassette tape has been inserted into the car stereo. If not, the flow proceeds to step J. Here, the movable operation surface is released. If it has been inserted, the flow proceeds to step M, where the movable operation surface is opened, and the cassette tape is ejected in step N. Next, in step K, it is determined whether or not a cassette tape is present in the insertion opening of the movable operation surface. If yes, the flow proceeds to step F, where it is determined whether or not the categorical tape is inserted into the car stereo again. Is determined. If it has not been inserted, the flow returns to step K. If it has been inserted, the flow proceeds to step G. Here, after loading the cassette tape, the flow proceeds to step H.
[0013]
If it is determined in step K that there is no cassette tape, the flow proceeds to step L, where it is determined whether or not the count (a predetermined time set in advance by the setting timer 7) has ended. This is determined by timing by the timing means of the control means 6. If not completed, the flow returns to step K. If completed, the flow proceeds to step H, where the movable operation surface is closed. In step L, as described above, in a state where the power is on and the movable operation surface is open, it is assumed that the cassette tape is to be replaced. It is provided so as not to close the movable operation surface.
[0014]
If the movable operation surface is opened while the power power is on and then the power supply is turned off (including the power supply being turned off by turning off the ACC power supply on the vehicle side), the movable operation surface is inserted. If there is no cassette tape in the mouth, the movable operation surfaces are closed at the time when the power supply is turned off, and when the cassette tape is present, the cassette tape is removed from the insertion slot. .
[0015]
According to this embodiment, when the power is on and the movable operation surface is open, as described in step L in FIG. After a lapse of a required minimum time, which is a time required for the replacement operation, the movable operation surface is closed, so that the following effects can be obtained.
(1) Even if the movable operation surface including the opening / closing mechanism is made of a material that is easily damaged from a safety point of view, the chance of contact with the movable operation surface during normal use other than during an accident is reduced. Thus, damage due to unnecessary causes can be prevented.
(2) Since the occupant is frequently released from the operation of closing the movable operation surface, a complicated operation is not forced. As a result, safe driving can be improved.
On the other hand, in a state where the power is off and the movable operation surface is released, the movable operation surface is immediately closed without passing the predetermined time as described above.
[0016]
In this embodiment, a car stereo has been described as an example. However, the present invention is not limited to this, and is similarly applied to other in-vehicle audio devices such as a CD player using a CD (compact disc) as a recording medium. can do.
[0017]
【The invention's effect】
According to the present invention, when the movable operation surface is driven to be closed when it is determined that there is no recording medium in the insertion opening of the movable operation surface in the open state of the movable operation surface, The time from when it is determined that there is no operation to when the movable operation surface is closed is set to be different based on the detection result of the power on and off, so after the required minimum time elapses Since the movable operation surface is closed, it is possible to prevent the movable operation surface from being damaged due to unnecessary causes, and to eliminate a complicated operation imposed on the occupant.
