Description

The present invention relates to an electronic device that moves a recording medium in and out of the main body when an openable / closable operation panel is in an open position.

Conventionally, it is controlled so as not to accept an operation on the operation unit of the operation panel between the time when the operation panel is opened and the position where the recording medium can be taken out from the main body is reached and the time after the arrival at a predetermined time. As a result, electronic devices that prevent malfunctions and malfunctions are known (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2008-77828

By the way, in the electronic device disclosed in Patent Document 1 described above, it is assumed that the operation panel (panel portion) is opened and closed electrically, and in the case of manually opening and closing, erroneous operation can be effectively prevented. There was a problem that it could not be done. For example, in the above-mentioned electronic device, a case where it is determined that the operation panel is moving until it reaches the extraction position of the recording medium is determined according to the drive current of the motor, but in the case of manual operation, this is described. Such a judgment method cannot be used. It is also possible to make this determination by using a sensor that can detect that the operation panel is moving, but in this case, it is desirable from the viewpoint of suppressing cost increase because another part is added. There is no.

Further, in the electronic device disclosed in Patent Document 1, the operation on the operation unit (panel operation unit) is not accepted for a predetermined time (predetermined time) after the operation panel reaches the extraction position of the recording medium. However, when the operation panel is manually closed, the operation unit may be touched when the operation panel is closed even after a predetermined time has elapsed, so that an erroneous operation due to this contact occurs.

The present invention has been created in view of these points, and an object of the present invention is to provide an electronic device capable of preventing erroneous operation of the panel operation unit when the panel unit is manually opened and closed. is there.

In order to solve the above-mentioned problems, the electronic device of the present invention has a main body in which a recording medium can be taken in and out, and a panel operation unit, which is opened and closed by a user's manual operation in order to put in and take out the recording medium. Panel operation based on the panel unit to be detected, the detection means for detecting that the panel unit is in the open state beyond the retrievable position of the recording medium, the detection result by the detection means, and the operation continuation state of the panel operation unit. It is provided with an operation determination means for determining the validity / invalidity of the operation content of the unit.

As a result, even if the user accidentally touches the panel operation unit when manually operating the panel unit, the operation content that continues when the panel unit shifts from the open position to the closed position is invalidated. Therefore, it is possible to prevent erroneous operation of the panel operation unit that occurs when the panel unit is manually opened and closed.

Further, the above-mentioned operation determination means invalidates the operation content of the panel operation unit when it is detected that the panel unit is in the open state, and the detection means shifts the panel unit from the open state to the closed state. It is desirable to continue the invalid state of the operation content of the panel operation unit when the operation state of the panel operation unit that was invalidated before the detection continues even when is detected. Further, it is desirable that the above-mentioned operation determination means invalidates the operation content of the panel operation unit after the panel unit has shifted to the closed state until the continuation of the operation state of the panel operation unit is stopped. As a result, even if the user accidentally touches the panel operation unit when the panel unit is manually closed, the operation content of the panel operation unit becomes invalid until the user releases the panel unit. It is possible to effectively prevent erroneous operation of the panel operation unit that occurs when the panel unit is manually closed.

Further, the above-mentioned operation determination means is the operation content of the panel operation unit after the panel unit is shifted to the closed state until the continuation of the operation state of the panel operation unit is stopped and the first predetermined time elapses. It is desirable to disable. As a result, even when the user changes the panel part when the operation of closing the panel part is completed, it is possible to effectively prevent erroneous operation of the panel operation part until the series of operations for manually closing the panel part is completed. it can.

Further, the above-mentioned operation determination means operates the panel when it is detected that the panel unit has changed from the closed state to the open state, and when the operation state of the panel operation unit continues before and after the detection. It is desirable to invalidate the operation contents of the part retroactively at the start of the operation. As a result, even if the user accidentally touches the panel operation unit when the panel unit is manually opened, the operation content of the panel operation unit is invalidated by going back to the time when the panel operation unit is touched. Therefore, it is possible to effectively prevent erroneous operation of the panel operation unit that occurs when the panel unit is manually opened.

Further, it is desirable to further include a processing means for performing a predetermined process according to the operation content of the panel operation unit described above, and a processing state restoration means for restoring the processing content at the start of the operation by the processing means. As a result, even if the user accidentally touches the panel operation unit when the panel unit is manually opened, the erroneous operation of the panel operation unit is invalidated by going back to the time when the panel operation unit is touched. After that, it becomes possible to continue the processing.

Further, when the operation state of the panel operation unit described above continues, it is desirable to include a case where the operation state is temporarily interrupted within a second predetermined time or less. As a result, even when the panel unit is changed during opening and closing, it is possible to effectively prevent erroneous operation of the panel operation unit until a series of operations for manually opening and closing the panel unit are completed.

Further, it is desirable that the panel operation unit described above is a touch panel. This makes it possible to manually open and close the panel without worrying about erroneous operation when the touch panel is accidentally touched, and improves operability by eliminating the need for complicated operations such as canceling erroneous operation. be able to.

The front surface 110 is exposed when the disc D is taken in and out of the insertion port 120, and is covered and shielded by the panel portion 200 at other times.

The switch 24 is turned on and off according to the open / closed state of the panel unit 200. Specifically, in the switch 24, the angle of the panel portion 200 is in the counterclockwise direction with respect to the vertical direction (as shown in FIGS. 3 (A) and 3 (B), the left side of the main body 100 and the panel portion 200). It is turned on when it is 45 ° or more (when viewed from the surface), and it may be less than 45 ° (as shown in FIG. 3A), the panel portion 200 may be tilted clockwise with respect to the vertical direction. (Including) is turned off. In the present embodiment, the angle (45 °) at which the on state and the off state change exceeds the angle at which the tip of the disk D interferes with the panel portion 200 when the disk D is taken out, that is, this interference does not occur. Is set to. For example, it is assumed that the back side of the panel unit 200 interferes with the tip of the disk D when the panel unit 200 shifts from the open state to the closed state and the angle of the panel unit 200 reaches the vicinity of 40 °. The above-mentioned 45 ° angle is set with a slight margin at the angle of 40 ° when this interference occurs. The switch 24 is attached, for example, in the vicinity of the support portion 210, and is configured so that the movable section moves according to the open / closed state of the panel portion 200 to perform an on / off operation.

The input control unit 26 monitors the operation status of the operation unit 20, the touch panel 22, and the switch 24, and detects the input content by the user and the open / closed state of the panel unit 200.

The display processing unit 30 outputs video signals for displaying various operation screens and displays these screens on the display unit 32, and also displays the navigation processing unit 10, the TV tuner processing unit 14, the radio tuner processing unit 16, and AV. A video signal corresponding to each processing content of the processing unit 18 is output, and a screen showing these processing contents is displayed on the display unit 32. The display unit 32 is installed in the panel unit 200, is configured by using, for example, a liquid crystal display (LCD), and displays a screen corresponding to a video signal output from the display processing unit 30.

Is output from the speaker 42. In reality, an amplifier that amplifies the signal is connected between the digital-to-analog converter 40 and the speaker 42, but this amplifier is omitted in FIG. Further, although the combinations of the digital-to-analog converter 40 and the speaker 42 are provided for the number of reproduction channels, only one set is shown in FIG.

The control unit 50 is for controlling the entire in-vehicle device 1, and is realized by executing a predetermined program stored in a ROM, RAM, or the like on the CPU. Further, the control unit 50 determines the validity / invalidity of the operation content of the touch panel 22 according to the open / closed state of the panel unit 200, so that the open / close detection unit 51, the operation continuation determination unit 52, the operation invalidity determination unit 53, and the processing state It has an acquisition unit 54 and a processing state restoration unit 55.

The open / close detection unit 51 detects that the panel unit 200 is in an open state beyond the removable position of the disk D. Here, the "open state beyond the take-out position" refers to a state in which the panel portion 200 is located at an angle that does not interfere with the tip of the disk D at the take-out position. Specifically, the open / close detection unit 51 monitors the on / off state of the switch 24, and the switch 24 is in the on state that the panel unit 200 is in the open state beyond the ejectable position of the disk D.

The operation continuation determination unit 52 determines the operation state of the touch panel 22 (any position of the touch panel 22) in each of the cases where the panel unit 200 shifts from the closed state to the open state and conversely when the panel unit 200 shifts from the open state to the closed state. It is determined whether or not the state (a state in which a part of the user's hand is touched) continues.

The operation invalidity determination unit 53 determines whether the operation content using the touch panel 22 is valid / invalid based on the detection result by the open / close detection unit 51 and the determination result by the operation continuation determination unit 52. Specifically, the operation invalidity determination unit 53 invalidates the operation content of the touch panel 22 when it is detected that the panel unit 200 is in the open state, and the panel unit 200 shifts from the open state to the closed state. When the operation state of the touch panel 22 that was invalidated before the detection continues, the invalid state of the operation content of the touch panel 22 is continued. The invalid state of the operation content is continued until the user who has touched the touch panel 22 releases the hand. Alternatively, the operation invalidity determination unit 53 detects that the panel unit 200 has changed from the closed state to the open state, and when the operation state of the touch panel 22 continues before and after the detection, the touch panel 22 The operation content using is invalidated retroactively at the start of the operation.

The processing state acquisition unit 54 is necessary to specify the processing state at the start of this operation (the navigation processing unit 10 or the like that is executing some processing immediately before the start of the operation, and to restore (reproduce) the processing content. Information) is acquired and stored.

The processing state restoration unit 55 restores the processing state acquired and stored by the processing state acquisition unit 54. As a result, the processing state at the start of the operation described above is reproduced.

The disk drive device 60 is for reading the signal recorded on the disk D, and includes a transport unit 62, a signal reading unit 64, a signal processing unit 66, and a disk detecting unit (DD) 68.

The transport unit 62 is for taking the disc D in and out of the main body 100, takes the disc D into the main body 100 from the insertion port 120, arranges the disc D on the turntable (not shown) of the signal reading unit 64, and ejects the disc D. When the key 124 is pressed, the disc D is taken out from this turntable and ejected from the insertion slot 120. The signal reading unit 64 reads the signal recorded on the disc D while rotating the disc D arranged on the turntable at a constant linear velocity. The signal processing unit 66 reproduces video data and music data based on the signal read by the signal reading unit 64. The disk detection unit 68 is for detecting whether or not there is a disk D protruding from the insertion port 120, and is configured by using, for example, a photodiode installed near the insertion port 120.

The open / close detection unit 51 described above is used as a detection means, the operation invalidity determination unit 53 is used as an operation determination means, the processing state restoration unit 55 is used as a processing state restoration means, and the navigation processing unit 10, TV tuner processing unit 14, and radio tuner processing unit 16 are used. , AV processing unit 18 corresponds to each processing means.

The in-vehicle device 1 of the present embodiment has such a configuration, and then when the user touches the touch panel 22 when the user manually pushes up and closes the panel portion 200 in the open state. The operation of is explained.

FIG. 5 is a flow chart showing an operation procedure for determining valid / invalidity of the operation content of the touch panel 22 when the panel unit 200 in the open state is closed.

The operation invalidity determination unit 53 determines whether or not the touch panel 22 has been operated (whether or not at least a part of the user's hand touches the touch panel 22) (step 100).

Next, the operation invalidity determination unit 53 determines whether or not the panel unit 200 is open based on the detection result of the open / close detection unit 51 (step 102). When the switch 24 is in the ON state (when the panel unit 200 is opened at an angle of 45 ° or more), a positive judgment is made. In this case, the operation invalidity determination unit 53 invalidates the operation content using the touch panel 22 (step 104). After that, the process returns to step 100, and the presence / absence determination of the operation using the touch panel 22 is repeated.

Further, when the switch 24 is in the off state (when the angle of the panel portion 200 does not reach 45 °), a negative determination is made in step 102. Next, in the operation continuation determination unit 52, a part of the user's hand is placed in the operation state of the touch panel 22 (a part of the user's hand is placed at any position of the touch panel 22) until the panel unit 200 shifts from the open state to the current closed state. It is determined whether or not the touched state) continues (step 106).

If it is continued, an affirmative determination is made, and the process of moving to step 104 and invalidating the operation content using the touch panel is continued. Further, when the operation state of the touch panel 22 is not continued, a negative determination is made in the determination in step 106, and the navigation processing unit 10 or the like performs processing according to the operation using the touch panel 22 (step 108).

As described above, in the in-vehicle device 1 of the present embodiment, even if the user accidentally touches the touch panel 22 when the panel unit 200 is manually closed, the panel unit 200 is moved from the open position to the closed position. Since it is possible to invalidate the operation content that is being continued when the transition is made, it is possible to prevent an erroneous operation using the touch panel 22 that occurs when the panel unit 200 is manually closed. In particular, even if the user accidentally touches the touch panel 22 when the panel unit 200 is manually closed, the operation content using the touch panel 22 becomes invalid until the panel unit 200 is released. It is possible to effectively prevent an erroneous operation that occurs when the panel portion 200 is manually closed.

FIG. 6 is a flow chart showing an operation procedure of a modified example of determining the validity / invalidity of the operation content of the touch panel 22 when the panel unit 200 is opened.

The operation invalidity determination unit 53 determines whether or not the touch panel 22 has been operated (whether or not at least a part of the user's hand touches the touch panel 22) (step 200).

Next, the operation invalidity determination unit 53 determines whether or not the panel unit 200 is closed based on the detection result of the open / close detection unit 51 (step 202). When the switch 24 is on (when the panel portion 200 is opened at an angle of 45 ° or more), a negative determination is made. In this case, the operation invalidity determination unit 53 invalidates the operation content using the touch panel 22 (step 204). After that, the process returns to step 200, and the presence / absence determination of the operation using the touch panel 22 is repeated.

Further, when the switch 24 is in the off state (when the angle of the panel portion 200 does not reach 45 °), a positive determination is made. In this case, the processing state acquisition unit 54 acquires and stores the processing state immediately before the touch panel 22 is operated (step 206). After that, processing according to the operation using the touch panel 22 is performed by the navigation processing unit 10 or the like (step 208).

Next, the operation invalidity determination unit 53 continues to operate the touch panel 22 (a state in which a part of the user's hand touches any position of the touch panel 22) while the panel unit 200 is in the closed state. Whether or not it is determined (step 210). If it is not continued, a negative determination is made, the process returns to step 200, and the presence / absence determination of the operation using the touch panel 22 is repeated.

Further, when the operation state of the touch panel 22 continues, a positive judgment is made in the determination in step 210. Next, the operation invalidity determination unit 53 determines whether or not the panel unit 200 has been opened based on the detection result of the open / close detection unit 51 (step 212). If the open state has not been reached, a negative determination is made, and the operation continuation determination in step 210 is repeated.

Further, when the panel unit 200 is opened while the operation is continued, a positive determination is made in the determination in step 212. Next, the operation invalidity determination unit 53 invalidates the operation content using the touch panel 22 (step 214). Further, the processing state restoration unit 55 restores the processing state stored by the processing state acquisition unit 54 (step 216). As a result, the operation content using the touch panel 22 can be invalidated retroactively at the start of the operation, and the processing state at the start of the operation can be reproduced.

As described above, in the in-vehicle device 1 of the present embodiment, even if the user accidentally touches the touch panel 22 when the panel unit 200 is manually opened, the touch panel goes back to the time when the touch panel 22 is touched. Since the operation content using the 22 is invalid, it is possible to effectively prevent an erroneous operation using the touch panel 22 that occurs when the panel unit 200 is manually opened.

Further, even if the touch panel 22 is accidentally touched when the user manually opens the panel unit 200, the erroneous operation using the touch panel 22 is invalidated by going back to the time when the touch panel 22 is touched. It becomes possible to continue the processing by the navigation processing unit 10 and the like.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the gist of the present invention. For example, in step 106 of FIG. 5, it is determined whether or not the operation state of the touch panel 22 is continued, but in this "when the operation state is continued (when a positive determination is made in the determination in step 106)", , The period from when the continuation of the operating state is stopped until the first predetermined time elapses may be included. As a result, even when the user changes the panel unit 200 when the operation of closing the panel unit 200 is completed, the erroneous operation using the touch panel 22 is effectively performed until the series of operations for manually closing the panel unit 200 is completed. Can be prevented.

Further, in the "when the operation state continues (when the affirmative determination is made in the determination of steps 106 and 210)" in step 106 of FIG. 5 and step 210 of FIG. 6, the second operation state is being continued. The case where the operation state is temporarily interrupted within a predetermined time may be included. As a result, even when the panel unit 200 is changed during opening and closing, it is possible to effectively prevent an erroneous operation using the touch panel 22 until a series of operations for manually opening and closing the panel unit 200 are completed.

Further, in the above-described embodiment, the case where the panel unit 200 is provided with the touch panel 22 has been described, but instead of the touch panel 22, or when the panel unit 22 is provided with a panel operation unit including various operation buttons and the like. The present invention can also be applied to.

Further, in the above-described embodiment, the in-vehicle device 1 as an electronic device mounted on a vehicle has been described, but the present invention also relates to an electronic device used other than the vehicle as long as it is an electronic device having a main body 100 and a panel unit 200. Can be applied.

As described above, according to the present invention, even when the panel unit is accidentally touched when the user manually operates the panel unit, when the panel unit shifts from the open position to the closed position. Since it is possible to invalidate the operation contents that continue to the above, it is possible to prevent erroneous operation of the panel operation unit that occurs when the panel unit is manually opened and closed.
