Description

  The present invention relates to an on-vehicle device with a monitor such as an audio device or a navigation device mounted on a vehicle and using a disk as an information recording medium.

  Conventionally, an in-vehicle device with a monitor such as an in-vehicle television has been proposed (see, for example, Patent Document 1). In this conventional vehicle-mounted device with a monitor, a monitor support member (slide plate) is slidably housed in the upper stage of an external housing that opens forward, and the monitor unit is at the end of the monitor support member at the end. It is supported by the part so that rotation is possible. The monitor unit is housed in the external housing in a horizontal state together with the monitor support member (this state is referred to as the housing state), and the monitor support member slides so that the tip end portion is opened from the opening of the external housing. Stand up with the display surface facing forward in a protruding state (this state is called an open state). Thus, the monitor unit is operable between the housed state and the open state.

  An operation panel is housed in the lower step of the external casing so as to be slidable in the front-rear direction. The front end of the monitor support member is locked to the operation panel, and the operation panel slides in the external housing together with the slide operation of the monitor support member in the external housing. When the monitor support member advances from the external housing and the monitor unit is in the open state, the operation panel slides and moves forward of the opening of the external housing along with the slide movement of the monitor support member. Pulled out. Further, when the monitor support member is retracted into the outer casing and the monitor unit is in the retracted state, the operation panel is slid and moved inward of the outer casing when the monitor support member is slid. Returned to

In such an in-vehicle device with a monitor, when the monitor unit is in an open state, the operation unit can be pulled out from the external housing so that the operation surface and the foremost position of the monitor unit are substantially aligned. . For this reason, it is possible to prevent the operation surface of the operation panel located in the lower stage portion of the external casing from being difficult to see from the vehicle occupant due to the shadow of the monitor unit standing in front of the opening of the external casing. it can.

  However, in the above-described in-vehicle device with a monitor, when the monitor unit is kept in a state where the display surface stands up frontward in front of the opening of the external housing (open state), the operation panel is moved back and forth. I can't do it. For this reason, for example, in an in-vehicle device with a monitor that uses a disk as an information recording medium, such as an audio device, when the monitor unit is in an open state, the operation panel in which the disk insertion slot is formed is located in front of the opening of the external housing. Accordingly, when the disc is ejected, the projection amount from the disc insertion opening in the operation panel of the disc fed out from the disc drive mechanical unit in the external housing is reduced. For this reason, it becomes difficult to remove the disc from the disc insertion port of the operation panel.

  The present invention has been made to solve the above-described conventional problems, and prevents an operation surface and a display surface of a panel unit from becoming difficult to be visually recognized by a monitor unit that is in an open state, while a disk that is ejected. It is intended to provide an in-vehicle device with a monitor that can be easily taken out.

  An in-vehicle disk device with a monitor according to the present invention has an external housing that opens forward, a storage state that is horizontally stored in an upper portion of the external housing, and a display surface that projects forward of the opening of the external housing. A monitor unit that is operable between an open state that rises toward the front, a disk drive mechanical unit that is housed in the lower step of the external housing, and a disk insertion unit that is disposed in front of the disk drive mechanical unit. A panel unit having a mouth, and a first position closer to the opening of the external housing than the foremost position of the monitor unit in the open state, and a first position further forward than the first position. A slide mechanism that slides between the first position and the second position, and when the monitor unit is in an open state, the panel unit is moved between the first position and the second position. A configuration in which a control means for controlling the sliding mechanism so as to id moved.

  With such a configuration, when the monitor unit is held in the open state with the display surface rising forward in front of the opening of the external casing, the panel unit is moved from the frontmost position of the monitor unit to the external casing. It becomes possible to slide between a first position close to the opening and a second position further forward than the first position. As a result, when the disc is ejected from the disc drive mechanical unit, the panel unit is moved from the foremost position of the monitor unit to the first position close to the opening of the external housing, and the panel unit is accommodated in the external housing. It is possible to make the disk drive mechanical unit closer. As a result, the disc ejected from the disc drive mechanical unit at a constant feed amount can be ejected from the disc insertion opening of the panel unit with a relatively large protruding amount. In addition, when performing disk loading or other operations, the panel unit is moved to the second position further forward than the first position, and becomes a shadow of the monitor unit that opens the panel unit. Can be prevented as much as possible.

  In the in-vehicle device with a monitor according to the present invention, the control unit may include a slide mechanism so that the panel unit slides from the first position to the second position based on a predetermined first operation. It can be set as the structure controlled.

  With such a configuration, the vehicle occupant can prevent the monitor unit from being in the shadow of the open state by performing the first operation, for example, when inserting a disc from the disc insertion slot or performing another operation. The panel unit can be moved to the second position to be obtained.

  In the in-vehicle device with a monitor according to the present invention, the control unit may include a slide mechanism so that the panel unit slides from the second position to the first position based on a predetermined second operation. It can be set as the structure controlled.

  With such a configuration, the vehicle occupant, for example, performs a second operation when ejecting the disc from the disc drive mechanical unit, thereby bringing the panel unit closer to the disc drive mechanical unit housed in the external housing. Can be moved to the second position.

  Furthermore, in the in-vehicle device with a monitor according to the present invention, when the control means performs an operation for ejecting a disk from the disk drive mechanical unit as the second operation, the panel unit is attached to the second unit. The slide mechanism can be controlled to slide from the position to the first position.

  With this configuration, when the vehicle occupant performs an operation for ejecting the disk from the disk drive mechanical unit, the panel unit is automatically brought closer to the disk drive mechanical unit housed in the external housing. It can be moved to position 1. Based on the above operation, the disc ejected from the disc drive mechanical unit at a constant feed amount can be ejected from the disc insertion opening of the panel unit with a relatively large protruding amount.

  The timing at which the disk is actually ejected from the disk drive mechanical unit after the operation for ejecting the disk from the disk drive mechanical unit can be arbitrarily set. The timing may be before, after, or at the same time before the panel unit moves to the first position.

  In the in-vehicle device with a monitor according to the present invention, the control means slides the panel unit from the second position to the first position before the disk ejecting operation is started from the disk drive mechanical unit. It is possible to adopt a configuration for controlling the slide mechanism so as to make it happen.

  With such a configuration, the disk is ejected from the disk drive unit after the panel unit is moved to the first position that is closer to the disk drive mechanical unit housed in the external housing. For this reason, since the disk is ejected from the disk drive mechanical unit while the panel unit is closer to the disk drive mechanical unit, the side of the disk insertion slot formed in the panel unit that faces the disk drive mechanical unit. Therefore, the disc can be surely ejected from the disc insertion opening without forming a sufficient guide portion.

  According to the in-vehicle disk device with a monitor according to the present invention, when the monitor unit is held in the open state with the display surface rising forward in front of the opening of the external housing, the panel unit is moved to the foremost part of the monitor unit. The disc is moved to a first position closer to the opening of the external housing than the position, that is, a position closer to the disk drive mechanical unit housed in the external housing, and is ejected from the disk drive mechanical unit at a constant feed amount. Can be discharged from the disk insertion opening of the panel unit with a relatively large amount of protrusion, and the panel unit is moved to a second position further forward than the first position, that is, a position further forward from the opening of the external housing. By moving the panel unit, it is possible to prevent the panel unit from becoming a shadow of the open state as much as possible. As a result, it is possible to easily take out the ejected disc while preventing the monitor unit in the open state from being difficult to visually recognize the operation surface and display surface of the panel unit.

  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows the external appearance of the in-vehicle apparatus with a monitor according to the present invention in a state where the operation panel unit is in the retracted position (first position). Moreover, the external appearance in the state in which the operation panel unit of this vehicle equipment exists in an advance position (2nd position) is shown by FIG. This in-vehicle device with a monitor is, for example, an in-dash type audio device with a monitor housed in an instrument panel of a vehicle, and plays back a disc such as a CD (compact disc) or a DVD (digital versatile disc). Do.

  As shown in FIGS. 1A to 1D, the audio device with a monitor (hereinafter simply referred to as an in-vehicle device) includes an external housing 10 that opens forward, an operation panel unit 20, and a monitor unit 30. Have. As shown in FIGS. 1B and 1C, the monitor unit 30 is rotatably supported by a tip end portion of a monitor support member 31 that is accommodated in the upper stage portion of the external housing 10 so as to be slidable in the front-rear direction. The As the monitor support member 31 slides in the front-rear direction within the external housing 10, the monitor unit 30 is stored horizontally in the external housing 10 (see FIG. 1A), and the external housing It can operate between the open state (see FIGS. 1B and 1C) that protrudes forward of the opening 10a of the body 10 and stands up with the display surface facing forward. The coupling mechanism between the monitor unit 30 and the monitor support member 31 and the slide movement mechanism of the monitor support member 31 are the same as those known in the art.

  The operation panel unit 20 is slidable in the front-rear direction at the lower stage portion of the external housing 10, and in the state shown in FIG. The retracted position is close to the opening 10a of the housing 10. When the monitor unit 30 is in the retracted state, the operation surface of the operation panel unit 20 in the retracted position and the foremost position Pclose of the monitor unit 30 are substantially aligned as shown in FIG. When the monitor unit 30 is in the open state, as shown in FIG. 1C, the disk insertion slot 21 formed on the operation surface of the operation panel unit 20 in the retracted position and the operation provided on the operation surface. The key group 22 (see FIG. 1D) becomes a shadow of the monitor unit 30, and the disk insertion port 21 and the operation key group 22 are difficult to visually recognize for the vehicle occupant.

  Further, as shown in FIG. 2, the operation panel unit 20 is slidable from the retracted position to a further advanced position. When the monitor unit 30 is in the open state, as shown in FIGS. 2A and 2B, the operation surface of the operation panel unit 20 at the forward position and the foremost position Popen of the monitor unit 30 are substantially aligned. It becomes. In this case, the disk insertion slot 21 and the operation key group 22 (see FIG. 2C) on the operation surface of the operation panel unit 20 at the forward position are not shaded by the monitor unit 30, and the disk insertion slot 21 and The operation key group 22 is easily visible.

  A slide mechanism for the operation panel unit 20 is provided in the external housing 10. The state of the slide mechanism when the operation panel unit 20 is in the retracted position (see FIG. 1) is shown in FIGS. 3 and 4, and the operation panel unit 20 is in the advanced position (see FIG. 2) further forward than the retracted position. The state of the slide mechanism in this case is shown in FIGS. 3 to 6, the outer casing 10 is shown with its upper surface omitted. Further, in FIGS. 3B, 4, 5B, and 6, the outer casing 10 is shown. The body 10 is shown with one side omitted.

  As shown in FIG. 3A, a slide plate 11 that can slide in the front-rear direction along the bottom surface of the external housing 10 is provided. As shown in FIGS. 3A and 3B, slide support portions 111 a and 111 b extending to the back side of the external housing 10 are formed at both end portions of the slide plate 11. Slits 112a and 112b are formed in the slide support portions 111a and 111b, and pins 12a and 12b erected at predetermined positions on the side end portions in the outer casing 10 are slidably engaged with the slits 112a and 112b. is doing.

  A rack 113 is formed on the inner side surface of one slide support member 111b. A motor 15 is fixedly installed near the slide support member 111b in the external housing 10. The gear train 13 is disposed between the gear mounted on the rotation shaft of the motor 15 and the rack 113, and the rotational movement of the gear train 13 driven by the motor 15 is converted into the horizontal movement of the rack 13, thereby the slide plate. 11 slides in the front-rear direction.

  As shown in FIG. 4A, the operation panel unit 20 is fixedly installed on the slide plate 11. A mechanical housing notch 23 is formed on the rear side of the operation panel unit 20, and as shown in FIG. 4B, the front portion of the disk drive mechanical unit 40 accommodated in the lower step of the external housing 10. However, it will be in the state fitted in the mechanical accommodation notch part 23 of the operation panel unit 20 in a retracted position. When the operation panel unit 20 is in the retracted position as described above, the distance between the disk insertion slot 21 formed on the operation surface of the operation panel unit 20 and the front end surface of the disk drive mechanical unit 40 is minimized, and the disk drive mechanical unit 40 The disc 50 ejected from the disc can protrude from the disc insertion slot 21 until its center hole 51 appears. In the disk drive mechanical unit 40, a disk transport mechanism (not shown) composed of a transport roller and a transport motor that rotationally drives the transport roller is mounted, and is inserted into the disk insertion slot 21 by the disk transport mechanism. The disc 50 is loaded into the disc drive mechanical unit 40 and the disc 50 is ejected from the disc drive mechanical unit 40 to the disc insertion slot 21.

  As shown in FIGS. 5A and 5B, the slide plate 11 can advance to the front of the opening 10 a of the external housing 10 by driving the motor 15. As the slide plate 11 moves forward, the operation panel unit 20 slides further from the retracted position to the forward advanced position as shown in FIG. At this time, as shown in FIG. 6B, the disk drive mechanical unit 40 fitted in the mechanical housing notch 23 of the operation panel unit 20 is relatively separated from the operation surface of the operation panel unit 20. Thus, even if the operation surface and the disk drive mechanical unit 40 are relatively separated from each other, the tip of the disk 50 inserted from the disk insertion port 21 reaches the disk transport mechanism (not shown) of the disk drive mechanical unit 40. Thus, the advance amount of the transfer panel unit 20 is set.

  The drive control system of the operation panel unit 20 is configured as shown in FIG.

  In FIG. 7, a monitor state sensor 61 for detecting whether the monitor unit 30 is in the housed state (see FIG. 1 (a)) or the open state (see FIGS. 1 (b) to (d), FIG. 2). Of the operation key group 22 provided on the operation panel unit 20, a disk eject (EJECT) key 22 a and an advance button 63 provided at an appropriate position of the operation panel unit 20 or the monitor unit 30 are connected to the control unit 60. Yes. The control unit 60 controls the drive circuit 62 of the motor 15 serving as the drive source of the operation panel unit 20 based on the detection signal from the monitor state sensor 61 and the operation signals from the disk ejection key 22a and the advance button 63.

  The monitor unit 30 is driven independently of the operation panel unit 20. For example, when the monitor unit 30 is in the storage state as shown in FIG. 1A, if a predetermined opening operation is performed, the monitor unit 30 advances from the external housing 10 with the advancement of the monitor support member 31, With the monitor unit 30 completely exposed from the external housing 10, the monitor support member 31 moves backward while the monitor unit 30 stands up so that the display screen faces forward, as shown in FIGS. It will be in the open state as shown. In this state, when a predetermined closing operation is performed, the monitor unit 30 is tilted forward, and the monitor support member 31 is moved backward in a state where the monitor unit 30 is substantially horizontal with the display surface 30a facing downward. The storage state returns to that shown in FIG.

  Independently of the drive of the monitor unit 30 as described above, the control unit 60 controls the operation of the operation panel unit 20 according to the procedure shown in FIG.

  In FIG. 8, the control unit 60 confirms whether or not the advance operation of the operation panel unit 20 has been performed based on the presence or absence of an operation signal from the advance button 63 (S1). When the operation signal from the advance button 63 is input to the control unit 60 (YES in S1), the monitor unit 20 is in either the open state or the stored state based on the state of the detection signal from the monitor state sensor 61. It is determined whether there is (S2). If it is determined that the monitor unit 20 is in the open state (YES in S2), the control unit 60 controls the drive circuit 62 to slide the operation panel unit 20 in the retracted position to the advanced position (S3). The operation panel unit 20 slides to the advanced position by the rotational movement of the motor 15 by the drive signal from the drive circuit 62 based on the control (see FIGS. 5 and 6).

  When the operation panel unit 20 reaches the advanced position in this manner, as shown in FIG. 9, the operation surface of the operation panel unit 20 is substantially aligned with the foremost position Popen of the monitor unit 30 in the open state ( (See also FIG. 2). As a result, the operation surface does not become a shadow of the monitor unit 30, and the vehicle occupant can easily insert the disk 50 from the disk insertion port 21 formed on the operation surface, and is provided on the operation surface. The operation key group 22 can be easily operated.

  The control unit 60 executes the control (S3) for moving the operation panel unit 20 to the advanced position described above, and then whether or not the disk 50 is ejected based on the presence / absence of an operation signal from the disk ejection key 22a. (S4). In this state, when an operation signal is input from the disk ejection key 22a (YES in S4), the control unit 60 controls the drive circuit 62 so as to slide the operation panel unit 20 in the advanced position to the retracted position. To do. The operation panel unit 20 slides to the retracted position by the rotational movement of the motor 15 by the drive signal from the drive circuit 62 based on the control (see FIGS. 3 and 4).

  When the operation panel unit 20 reaches the retracted position in this manner, as shown in FIG. 4B, the operation surface of the operation panel unit 20 and the front end surface of the disk drive mechanical unit 40 accommodated in the external housing 10 are obtained. The distance between and is minimized. In this state, the control unit 60 further controls to eject the disk 50 from the disk drive mechanical unit 40 (S6). As a result, the disk 50 is ejected from the disk drive mechanical unit 40. In this case, since the distance between the operation surface of the operation panel unit 20 and the front end surface of the disk drive mechanical unit 40 is minimized, the disk 50 ejected from the disk drive mechanical unit 40 with a constant feed amount is shown in FIG. As shown in the figure, the disc is ejected from the disc insertion slot 21 of the operation panel unit 20 with a relatively large protruding amount such that the center hole 51 appears (see also FIG. 4B). As a result, even if the operation surface of the operation panel unit 20 becomes a shadow of the monitor unit 30 in the open state, the vehicle occupant puts the palm on the tip of the disk 50 protruding from the disk insertion port 21 and enters the center hole 51. The disk 50 can be easily taken out with a finger.

  Note that the control panel 60 may automatically move the operation panel 20 from the retracted position to the side advanced position when it is detected by a sensor (not shown) that the disk 50 has been pulled out from the disk insertion slot 21. This facilitates the insertion operation when another disc is inserted into the disc insertion slot 21.

  Thereafter, the control unit 60 performs the same process each time the advance button 63 for causing the operation panel unit 20 to advance is operated. In this example, when the advance button 63 is operated (YES in S1), if the monitor unit 30 is in the retracted state (NO in S2), the control unit 60 does not execute the subsequent processes (S3 to S6). Therefore, when the monitor unit 30 is in the retracted state, the operation panel unit 20 remains in the retracted position even if the advance button 63 is operated. Since the slide mechanism of the operation panel unit 20 (see FIGS. 3 to 6) and the slide mechanism of the monitor unit 30 are independent, when the advance button 63 is operated, the monitor unit 30 is stored and opened. In any state, the operation panel unit 20 can be slid to the advanced position.

  The retracted position (first position) of the operation panel unit 20 is determined based on the relationship with the most complete position Pclose of the monitor unit 30 that is in the housed state, the amount of ejection movement of the disk 50 from the disk drive mechanical unit 40, and the like. be able to. The advancement position (second position) of the operation panel unit 20 is the ease of operation of the operation surface when the monitor unit 30 is in the open state, and the tip of the disk 50 inserted from the disk insertion slot 21 is the disk. The determination can be made based on whether or not the drive mechanism unit 40 has reached an appropriate position. Therefore, in the advanced position, the operation surface of the operation panel unit 20 and the foremost position Popen of the monitor unit 30 in the open state are not necessarily aligned.

  In the above-described example, when the disc ejection key 22a is operated, the operation panel unit 20 at the advanced position is moved to the retracted position. However, other operations such as a dedicated operation button are operated. Sometimes, the operation panel unit 20 can be moved to the retracted position. In the example described above, the operation panel unit 20 in the advanced position is moved to the retracted position and then the disc 50 is ejected. However, after the disc 50 is ejected, the operation panel unit 20 is retracted. Even if it is moved to the position, it is also possible to simultaneously eject the disk 50 and move the operation panel unit 20 to the retracted position. However, when the operation panel unit 20 is in the forward position, as shown in FIG. 6B, the disk insertion slot 21 formed in the operation panel unit 20 and the disk drive mechanical unit 40 accommodated in the external casing 10 The distance from the front end surface increases. Therefore, in this state, it is more likely that the disk 50 is ejected after the operation panel unit 20 is moved to the retracted position (see FIG. 4B) than the disk 50 is ejected. This is preferable in that the disc 50 can be reliably ejected from the disc insertion port 21 without forming a particularly sufficient guide portion on the side of the port 21 facing the disc drive mechanical unit 40.

  In the example described above, the operation panel unit 20 having the operation key group 22 is provided in the lower part of the external housing 10. However, instead of the operation panel unit 20, a disk insertion slot 21 and a display unit such as an LCD are provided. A display panel unit having the following may be slidably provided.

  The in-vehicle disk device with a monitor according to the present invention can easily take out the ejected disk while preventing the monitor unit that is opened from becoming difficult to visually recognize the operation surface and display surface of the panel unit. It is useful as an in-vehicle device with a monitor such as an audio device or a navigation device using a disk as an information recording medium.
