  8 to 10 are schematic perspective views for explaining the discharging operation and the starting operation of the display panel 2 of FIG.

  As shown in FIGS. 1, 2, and 4, the in-vehicle electronic device displays a main body 1 placed on a console box, a dashboard, or the like in the vehicle, and information such as image information that appears and disappears from the main body 1. The display panel 2 is provided as a main component. The display panel 2 is configured to be housed in the main body 1 as shown in FIG. 2, and is slid in the main body 1 by a panel driving member 3 provided in the main body 1 as shown in FIG. It is possible and can be tilted outside.

  As shown in FIGS. 2 and 4, the main body 1 has a square box shape constituted by a top plate and a bottom plate arranged opposite to each other and left and right side plates and a back plate arranged continuously on the outer periphery thereof. The front is open. Inside the main body 1, a disk reproducing device 4 attached to a chassis (not shown) is placed on the bottom side. The disc playback device 4 has the same configuration as that of the conventional disc playback device, and a description thereof is omitted here.

  A panel storage space 5 serving as a storage space for the display panel 2 and the panel driving member 3 is formed above the disk reproducing device 4. As shown in FIGS. 3 and 5, guide rails 6 for sliding movement of the display panel 2 and the panel driving member 3 are disposed on the inner surfaces of the left and right side plates of the main body 1 constituting the panel storage space 5. One guide rail 6 is provided with a slide stopper 7 protruding inward of the main body 1.

  As shown in FIGS. 2 and 4, a grill 8 that is a front cover is attached to the front surface (that is, the opening side) of the main body 1 so as to cover a portion where the disk reproducing device 4 is disposed. On the other hand, the panel storage space 5 of the main body 1 to which the grill 8 is not attached communicates with the outside.

  On the front surface of the grill 8, various input setting means (for example, a knob 81) for controlling the operation of the in-vehicle electronic device are provided. In addition, a disc insertion slot 82 (see FIG. 8) is formed on the front surface of the grill 8 with a predetermined width in the horizontal direction.

  As shown in FIG. 1, the display panel 2 has a display monitor 21 such as a liquid crystal display monitor, and image information and character information such as a navigation map screen and a television screen are displayed on the display surface 23 of the display monitor 21. Is displayed. The display panel 2 has a configuration in which the display monitor 21 is housed and disposed in a square box-shaped housing 22. The housing 22 covers the entire back surface and side surfaces of the display monitor 21 and covers the outer periphery of the display surface 23. It is framed. Here, the portion of the frame-shaped casing 22 that surrounds the display surface 23 is referred to as a frame member 24 of the casing 22. The frame member 24 is disposed along the edge of the rectangular display surface 23.

  Since the frame member 24 is disposed at the edge of the display surface 23, the frame member 24 protrudes from the display image 23 in a side view of the display panel 2. In particular, the frame member 24 placed along the upper side of the display surface 23 (hereinafter referred to as the upper side frame member 24a) is formed to be thicker than the frame member 24 arranged on the other three sides. Therefore, it protrudes greatly from the display surface 23 as compared with the frame material 24 on the other three sides. Here, the distance from the display surface 23 to the frame material surface is referred to as the thickness of the frame material 24. Here, the upper and lower sides of the display panel 2 are determined based on the startup state during use.

  As shown in FIG. 2, here, a space entrance in the front view of the main body of a space S (hereinafter referred to as a disc erroneous insertion space) S formed between the display panel 2 and the disc reproducing device 4 when the panel is housed. However, the thickness of the upper side frame member 24a is set so as to be covered by the upper side frame member 24a. That is, when the panel is stored, the disc erroneous insertion space S is hidden by the upper side frame member 24a of the display panel 2 when viewed from the front of the main body. As will be described later, in this embodiment, the upper side frame member 24a constitutes a first disc erroneous insertion prevention mechanism.

  The display panel 2 stored in the panel storage space 5 of the main body 1 is disposed horizontally in the panel storage space 5 with the display surface 23 facing downward. In such a state, the upper end portion of the display panel 2 on which the upper side frame member 24a is disposed is disposed on the front surface of the main body.

  A panel driving member 3 is disposed on the back side of the main body of the display panel 2. As will be described later with reference to FIGS. 8 to 10, the panel driving member 3 causes the display panel 2 to slide back and forth in the panel storage space 5 formed inside the main body 1, and display outside the main body 1. It is possible to tilt and move to an angle that allows easy viewing.

  Here, the front side of the main body is defined as the front side and the rear side of the main body is defined as the rear side, the slide movement toward the front is defined as forward, and the slide movement toward the rear (that is, the storing operation) is defined as the reverse.

  As shown in FIGS. 2 and 4, the panel driving member 3 includes an arm 33 serving as a panel supporting unit that supports the display panel 2, and a driving unit (not shown) for driving the display panel 2. Has been. Although not shown here, the driving means of the panel driving member 3 includes, for example, a motor that is a driving source, a transmission means such as a gear that transmits the rotation of the motor to the display panel 2 as a driving force, and a display panel. And a control means for detecting the slide movement amount and the tilt angle and controlling the rotation of the motor based on the detection result.

  The tip of the arm 33 of the panel driving member 3 is attached to a tilt shaft 34 disposed on the bottom side of the display panel 2. As a result, the display panel 2 is pivotally supported by the arm 33 of the panel drive member 3.

  A tilt-up gear (not shown) is disposed around the tilt shaft 34 of the display panel 2, while a tilt-up drive gear (not shown) that engages with the tilt-up gear is provided on the panel drive member 3. It is attached to the arm 33. With this configuration, the display panel 2 can rotate around the tilt shaft 34.

  As shown in FIGS. 3 and 5, the panel driving member 3 and the display panel 2 are placed on guide rails 6 that extend horizontally on the inner surfaces of the left and right side plates of the main body 1. As a result, the display panel 2 is supported in the panel storage space 5 so as to be slidable in a horizontally movable manner.

  Further, a second disk erroneous insertion preventing mechanism including a disk stopper 35 and a trigger lever 36 is disposed on the bottom surface of the panel driving member 3.

  Specifically, the second erroneous disk insertion preventing mechanism includes a disk stopper 35 attached to the bottom surface of the panel driving member 3, and a trigger lever 36 disposed between the bottom surface of the panel driving member 3 and the disk stopper 35. And a leaf spring 37 that presses the disk stopper 35 against the bottom surface side of the panel driving member 3. Here, the disc stopper 35 is made of a resin material, and the trigger lever 36 and the plate spring 37 are made of a metal material subjected to sheet metal pressing.

  The disk stopper 35 is a convex plate-like member in which squares are combined in a plan view. Specifically, the disk stopper 35 includes a quadrangular first region 351, a quadrangular second region 352 formed wider than the first region 351, and an L-shaped arm 353. .

  The first region 351 protrudes from the second region 352 to the display panel 2 side. The arm 353 has one L-shaped end connected to the second region 352 and the other end protruding to the opposite side of the display panel 2. The projecting other end of the arm 353 is pivotally supported by a mounting member 400 disposed on the bottom surface of the panel driving member 3 so that the disk stopper 35 is supported by the shaft 354 of the arm 353 (see FIG. 2 and FIG. 2). It is attached to the panel drive member 3 so as to be rotatable around the center (see FIG. 4). Here, a disk stopper 35 is disposed at substantially the center of the bottom surface of the panel driving member 3.

  As shown in FIGS. 6 and 7, predetermined steps are formed on the surfaces of the first and second regions 351 and 352 (see FIG. 3) of the disk stopper 35 facing the bottom surface of the panel drive member 3, respectively. As a result, the surface of the disk stopper 35 has irregularities. A disk contact head 355 that is in contact with the disk 100 (see FIG. 2) is formed in the first area 351 (see FIG. 3), which is partitioned by such irregularities, and the second area 352 (see FIG. 3). In addition, a slide stage 357 for sliding the trigger lever 36 is formed, and an arm storage groove 356 for storing the lever arm 362 of the trigger lever 36 is formed in a recess between the disk contact head 355 and the slide stage 357. .

  In the arm housing groove 356, the side wall on the disk contact head 355 side is formed at a steep angle with respect to the bottom surface of the groove as compared with the side wall on the slide stage 357 side. Further, the surface of the slide stage 357 is inclined so as to descend very gently from the arm housing groove 356 side toward the rear, and the thickness of the slide stage 357 is reduced accordingly. Accordingly, the slide stage 357 has a surface height that is substantially the same as that of the disk contact head 355 in the vicinity of the arm housing groove 356, but is lower than the disk contact head 355 as it goes rearward. Further, the tip of a leaf spring 37 (see FIGS. 3 and 5) is in contact with the back surface of the slide stage 357.

  On the other hand, the trigger lever 36 is attached to the bottom surface of the panel drive member 3 via a positioning pin 363 and a tension coil spring 364 as shown in FIGS. The trigger lever 36 includes a base 361 attached to one side of the panel driving member 3 by a positioning pin 363 and a tension coil spring 364, and an arrangement of the disk stopper 35 extending from the base 361 along the bottom side of the display panel 2. And a lever arm 362 reaching the position. The base 361 and the lever arm 362 are integrally formed by sheet metal pressing.

  The base 361 includes notches 365 formed at two locations for slide guides, spring locking portions 366, and slide stopper abutting protrusions 367. The notch 365 has a circular hole formed at a diameter larger than the protruding end of the positioning pin 363 inserted into the bottom surface of the panel driving member 3 with one end protruding, and extends backward from the circular hole. The positioning pin 363 has a stripe hole having a smaller diameter than the protruding end. The stripe hole of the notch 365 is formed in parallel with the side plate of the main body 1.

  When the trigger lever 36 is attached to the bottom surface of the panel driving member 3, the trigger lever 36 is disposed so that the positioning pin 363 is positioned in the circular hole of the notch 365, and then the trigger lever 36 is slid forward. Then, the positioning pin 363 is guided to the stripe hole. Thereby, the trigger lever 36 is sandwiched between the collar portion of the positioning pin 363 and the bottom surface of the panel drive member 3, and the trigger lever 36 is slidably engaged with the positioning pin 363.

  In addition, a slide stopper abutting protrusion 367 is provided at the rear end of the base 361 of the trigger lever 36 so as to protrude perpendicularly from the surface of the base 361 toward the disk reproducing device 4 (see FIGS. 2 and 4). As will be described in detail later, as shown in FIG. 5, the slide stopper abutting protrusion 367 abuts against the slide stopper 7 inside the main body 1 as the panel driving member 3 slides forward.

  Further, a claw-like spring locking portion 366 is disposed on the base portion 361 so as to face the slide stopper contact protrusion 367 inward. One end of the tension coil spring 364 is locked to the spring locking portion 366. The other end of the tension coil spring 364 is locked by a spring locking portion 368 disposed on the bottom surface of the panel driving member 3. The spring locking portion 368 has a claw shape similar to that of the spring locking portion 366.

  The tension coil spring 364 spanned between the two spring locking portions 366 and 368 is disposed with its axial direction coinciding with the extending direction of the notch 365. Further, as shown in FIG. 5, a notch 369 is formed in the base 361 so that the spring locking portion 368 and the base 361 of the trigger lever 36 do not come into contact when the tension coil spring 364 is extended. ing.

  On the other hand, as shown in FIGS. 3 and 5, the lever arm 362 of the trigger lever 36 has a width on the distal end side that is narrower than a width on the base 361 side in plan view. As will be described later, this narrow predetermined area on the tip side comes into contact with the surface of the disk stopper 35.

  A leaf spring 37 is attached so that the tip of a lever arm 362 attached to the bottom surface of the panel drive member 3 via the base 361 contacts the panel drive member 3.

  Next, the discharge operation and the storage operation of the display panel 2 will be described.

  First, as shown in FIG. 8, when the display panel 2 housed in the main body 1 is moved in and out, input is made to input setting means (not shown) arranged in front of the grill 8 (see FIG. 1). Then, the panel driving member 3 is driven. Specifically, the driving means (not shown) of the panel driving member 3 is driven and transmitted to the display panel 2 via a transmitting means (not shown) such as a driving force gear. As a result, as shown in FIG. 9, the display panel 2 together with the panel driving member 3 slides horizontally along the guide rail 6 (see FIG. 10) in the main body 1 and is discharged to the outside. .

  Here, in the sliding movement of the display panel 2 and the panel driving member 3, the movement amount of the display panel 2 is adjusted by a slide amount detection means (not shown) such as an optical sensor disposed in the main body 1. Detected. And based on this detection information, the drive means (not shown) of the panel drive member 3 is controlled by the control means (not shown). Thereby, the slide movement of the display panel 2 can be stopped at a predetermined discharge position.

  After the display panel 2 is discharged to the outside of the main body 1, as shown in FIG. 10, the panel driving member 3 tilts the display panel 2 so that the upper end of the display panel 2 disposed at the forefront is at the top as shown in FIG. Move. Thereby, the display panel 2 is started up and the display surface 23 is arranged in front. As described above, the display panel 2 appears and disappears by the discharge operation and the startup operation of the display panel 2.

  On the other hand, after the use of the display panel 2 is completed, input is performed again by the input setting means (not shown). Thereby, each operation in the reverse direction is performed in the reverse order to the above, and the display panel 2 that has appeared outside is housed in the main body 1 together with the panel driving member 3. That is, in the storing operation of the display panel 2, first, the upper end of the display panel 2 is lowered to the position at the time of ejection so that the display panel 2 is in a state of lying horizontally with the display surface 23 facing down. Tilt movement in the direction is performed, and then, the display panel 2 and the panel driving member 3 are slid rearward in the reverse direction to the above and moved back to the original storage position.

  Next, a disc insertion error preventing method according to this embodiment will be described together with the operation of the display panel 2.

  First, as shown in FIGS. 2 and 3, when the display panel 2 is stored in the main body 1, the display panel 2 is stored horizontally in the panel storage space 5 with the display surface 23 facing downward. In addition, a predetermined area above the panel including the upper end portion is exposed from the main body 1 to the front. In such an arrangement, the upper end portion of the display panel 2 including the upper side frame member 24 a is arranged in front of the main body 1, and the upper side frame member 24 a is inserted into a disc insertion slot (not shown) formed in front of the grill 8. It is arranged above this disc insertion slot.

  Here, as described above, the upper side frame member 24a is formed thicker than the frame member 24 of the other part and protrudes greatly toward the display surface 23 side. Therefore, when the main body 1 is viewed from the front, The upper end portion of the display panel 2 including the material 24 a covers the entrance of the disc erroneous insertion prevention space S formed between the display panel 2 and the disc playback device 4. Specifically, in the plan view from the front of the main body, the entrance of the disc erroneous insertion space S is completely accommodated in the arrangement region of the upper side frame member 24a.

  Thus, since the entrance and the outside of the disc erroneous insertion space S are separated from each other by the upper frame member 24a in a front view, the entrance of the disc erroneous insertion space S is conventionally opened to the outside, so that the disc erroneous insertion space S is opened. In the present embodiment, the disc 100 abuts against the upper side frame member 24a at the time of insertion, so that the disc 100 is prevented from being erroneously inserted into the disc erroneous insertion space S.

  The upper frame member 24a covers the entrance of the disc erroneous insertion space S as described above, but has a thickness that does not cover the disc insertion opening (not shown) of the grill 8. For this reason, the upper side frame member 24a does not hinder disc insertion into the disc insertion slot. In particular, here, the disc 100 can be easily inserted into the disc insertion slot by horizontally moving the disc 100 toward the main body along the surface of the upper frame member 24a (corresponding to the bottom when viewed from the front). It becomes possible.

  As described above, when the display panel 2 is stored, the upper side frame member 24a can prevent erroneous insertion of the disc. Therefore, in this embodiment, the upper side frame member 24a corresponds to the first disc erroneous insertion preventing means.

  On the other hand, as shown in FIG. 4 and FIG. 5, in the state where the display panel 2 appears and disappears, the display panel 2 is raised and the upper side frame member 24 a is disposed at a position different from the entrance of the disc erroneous insertion space S. Thus, it is impossible to prevent erroneous insertion of the disc by the upper side frame member 24a as described above. Therefore, in this case, the disc stopper 35 prevents erroneous disc insertion as follows.

  First, the state of the disc stopper 35 and the trigger lever 36 when the display panel 2 is housed in the main body 1 will be described. As shown in FIGS. 2 and 3, when the panel is housed, the positioning pin 363 contacts the rear end of the notch 365 of the trigger lever 36, and the trigger lever 36 is disposed at a position close to the display panel 2. In the trigger lever 36 having such an arrangement, the slide stopper abutting protrusion 367 of the base 361 is not in contact with the slide stopper 7 formed inside the main body 1. Further, the tension coil spring 364 receives only a slight tensile force and is held in the initial state.

  As shown in FIG. 6, in the arrangement of the trigger lever 36, the tip of the lever arm 362 of the trigger lever 36 is housed in the arm housing groove 356 of the disk stopper 35. In this state where the tip of the lever arm 362 is disposed in the arm storage groove 356, the bottom surface of the arm storage groove 356 is pressed by the lever arm 362, but the pressing force is alleviated by the amount of the groove formed. . Therefore, the disk stopper 35 configured to be rotatable around the shaft 354 has a balance between the downward pressing force from the lever arm 362 received on the front surface and the upward pressing force from the leaf spring 37 received on the rear surface. The panel drive member 3 is held substantially parallel to the bottom surface.

  Here, the position of the disk contact head 355 of the disk stopper 35 arranged in parallel in this way is referred to as an initial head position. The disk stopper 35 in which the disk contact head 355 is in the head initial position is not in contact with other members such as the disk reproducing device 4 inside the main body 1, and therefore does not interfere with other members and their operation. .

  Next, operations of the disc stopper 35 and the trigger lever 36 in the ejecting operation of the display panel in FIG. 9 will be described.

  When the panel drive member 3 slides forward as described above when the panel is ejected (see FIG. 9), the trigger lever 36 attached to the panel drive member 3 moves forward in the main body 1 together with the panel drive member 3. Move the slide. Hereinafter, the sliding movement in the same traveling direction as that of the panel driving member 3 attached to the panel driving member 3 will be referred to as a first sliding movement of the trigger lever 36.

  In the first sliding movement, the slide stopper abutting protrusion 367 of the trigger lever 36 does not abut against the slide stopper 7 and the tension coil spring 364 is in the initial state as in the case of the panel housing shown in FIG. Therefore, the position of the trigger lever 36 on the bottom surface of the panel driving member 3 in the first sliding movement is held at the position when the panel is housed as shown in FIG. Therefore, at the time of the first slide movement, as shown in FIG. 6, the tip of the lever arm 362 of the trigger lever 36 is housed in the arm housing groove 356 of the disk stopper 35 as in the case of housing the panel. In this state, the disk stopper 35 is disposed substantially parallel to the bottom surface of the panel driving member 3, and the disk contact head 355 is disposed at the head initial position.

  When the display panel 2 and the panel driving member 3 are slid forward by a predetermined amount, the slide stopper contact protrusion 367 of the trigger lever 36 contacts the slide stopper 7 of the main body 1 as shown in FIG. Here, when the entire display panel 2 is discharged to the outside and up to a predetermined portion of the panel driving member 3 is discharged to the outside, the slide stopper contact protrusion 367 of the trigger lever 36 contacts the slide stopper 7.

In this way, the display panel 2 and the panel driving member 3 are slid forward by a predetermined amount while the slide stopper abutting protrusion 367 of the trigger lever 36 is in contact with the slide stopper 7. In this sliding movement, the arrangement position of the trigger lever 36 in the inside of the main body 1 does not change (that is, it is held at the contact position with the slide stopper 7), but the panel driving member 3 slides forward, The relative position of the trigger lever 36 on the bottom surface of the panel drive member 3 changes.

  In this case, although the arrangement position of the trigger lever 36 in the main body 1 does not actually change, the trigger lever 36 is opposite to the display panel 2 and the panel drive member 3 when attention is paid to the relative arrangement on the bottom surface of the panel drive member 3. It can be considered that the slide is moving backward. Therefore, here, such a relative change in the arrangement of the trigger lever 36 on the bottom surface of the panel driving member 3 is referred to as a second slide movement of the trigger lever 36.

  By this second slide movement, the position of the trigger lever 36 on the bottom surface of the panel drive member 3 is rearward from the position when the panel is housed or the first slide movement shown in FIG. That is, the relative position of the positioning pin 363 that has been in contact with the rear end of the notch 365 changes to the front end side of the notch 365. Further, the tension coil spring 364 whose one end is locked to the spring locking portion 368 on the bottom surface of the panel driving member 3 is extended by this second sliding movement.

  With the second slide movement of the trigger lever 36, the relative arrangement of the trigger lever 36 (specifically, the tip of the lever arm 362) in the disk stopper 35 changes. That is, the trigger lever 36 is actually held at a position in contact with the slide stopper 7, but the disc stopper 35 slides in association with the forward slide movement of the panel drive member 3. The relative arrangement of 36 and the disk stopper 35 changes.

  Specifically, the tip of the lever arm 362 of the trigger lever 36 housed in the arm housing groove 356 exceeds the side wall of the arm housing groove 356 and the slide stage of the disk stopper 35 as shown in FIGS. It reaches the surface of 357 and slides backward along the surface of the slide stage 357. Here, since the side wall on the slide stage 357 side of the arm storage groove 356 has a gentler slope than the side wall on the disk contact head 355 side, the side wall does not become a barrier for the sliding movement of the lever arm 362. The lever arm 362 can easily reach the slide stage 357 from the arm housing groove 356.

  When the display panel 2 and the panel driving member 3 slide to the predetermined positions and the panel discharging operation is finished, the second sliding movement of the trigger lever 36 is finished. At the end of the second slide movement, as shown in FIG. 5, the positioning pin 363 comes into contact with the front end of the notch 365, and the trigger lever 36 is farthest from the display panel 2. At this time, the tip of the lever arm 362 of the trigger lever 36 is disposed at the rear end of the slide stage 357 of the disc stopper 35 as shown in FIG. Then, in the panel raising operation (specifically, the tilt movement of the display panel 2) following the panel discharging operation, the state where the lever arm 362 is arranged at the rear end of the slide stage 357 is maintained.

  As described above, the tip of the lever arm 362 disposed at the rear end of the slide stage 357 contacts the slide stage 357 and presses the surface downward. The pressing force at this time is closer to the object to be pressed (that is, the surface of the slide stage 357) than when the tip is housed in the arm housing groove 356. It becomes stronger than the pressing force when the is stored.

  Then, as shown in FIG. 7, the disk stopper 35 has a downward pressing force received on the surface of the slide stage 357 from the tip of the lever arm 362 and an upward force received from the back surface of the slide stage 357 by the leaf spring 37 (see FIG. 5). Due to the balance with the pressing force, it is rotated in a direction away from the bottom surface of the panel driving member 3 to be inclined. As a result, the disk contact head 355 of the disk stopper 35 is lowered and disposed below the initial head position shown in FIG. As shown in FIG. 4, the lowered disk contact head 355 contacts the upper surface of the grill 8. When the display panel 2 is started up and when the panel is used, the state where the disk contact head 355 is lowered is maintained.

  As shown in FIG. 4, in the state in which the display panel 2 is started up, it is not possible to prevent erroneous insertion of the disc by the upper side frame member 24a which is the first disc erroneous insertion preventing means as in the case of storing the panel. In this case, as described above, the disk contact head 355 of the disk stopper 35 descends and contacts the upper surface of the grill 8, so that the disk formed between the bottom surface of the panel support member 3 and the disk reproducing device 4. If the disc 100 is erroneously inserted into the erroneous insertion space S, the disc 100 comes into contact with the disc contact head 355 of the disc stopper 35, so that erroneous insertion into the erroneous disc insertion space S is prevented.

  Next, operations of the trigger lever 36 and the disk stopper 35 when the display panel 2 and the panel driving member 3 are housed in the main body 1 again will be described.

  When the display panel 2 and the panel driving member 3 are housed, the display panel 2 is laid horizontally with the display surface 23 facing downward as shown in FIG. At this time, since the position of the panel driving member 3 does not change, the trigger lever 36 and the disk stopper 35 are held in the state shown in FIG. 7 in which the disk contact head 355 is lowered.

  Subsequently, the display panel 2 and the panel driving member 3 in the state shown in FIG. 9 slide toward the rear of the main body 1 contrary to the time of discharging. At this time, until the sliding movement reaches a predetermined amount. As in the case of FIG. 5, the state where the slide stopper abutting protrusion 367 of the trigger lever 36 abuts against the slide stopper 7 is maintained. Such a contact state is automatically realized by contraction of the tension coil spring 364.

  Thus, when the panel drive member 3 slides backward with the slide stopper abutment protrusion 367 of the trigger lever 36 in contact with the slide stopper 7, the position of the trigger lever 36 inside the main body 1 does not change, but the panel drive Since the relative arrangement of the trigger lever 36 on the bottom surface of the member 3 changes, it can be considered that the trigger lever 36 slides forward on the bottom surface of the panel drive member 3. Therefore, here, such a change in the relative arrangement of the trigger lever 36 in the panel storing operation is referred to as a third slide movement of the trigger lever 36.

  By the third slide movement of the trigger lever 36, as shown in FIG. 3, the positioning pin 363 that has been in contact with the front end of the notch 365 is in contact with the rear end of the notch 365, and the trigger lever 36 is moved to the display panel. It is arranged at a position close to 2. Thus, in the trigger lever 36 disposed at a position close to the display panel 2, the contraction of the tension coil spring 364 is stopped and the initial state is maintained.

  With the third slide movement of the trigger lever 36, the tip of the lever arm 362 of the trigger lever 36 arranged at the rear end of the disk stopper 35 is connected to the slide stage of the disk stopper 35 as shown in FIG. Slide the surface of 357 forward.

As the disc stopper 35 slides at the tip of the lever arm 362, the force with which the tip presses the surface of the slide stage 357 downward, and the leaf spring 37 (see FIG. 3) is applied to the slide stage 357. The balance with the force of pressing the back surface upward changes, whereby the disk stopper 35 rotates so as to be close to the bottom surface of the panel drive member 3. As a result, the disk contact head 355 of the disk stopper 35 that has been lowered to the position where it contacts the upper surface of the grill 8 is raised.

  When the third slide movement is finished and the trigger lever 36 returns to a position close to the display panel 2 shown in FIG. 3, the tip of the lever arm 362 of the trigger lever 36 moves into the arm housing groove 356 as shown in FIG. It is stored in. When the tip of the lever arm 362 is housed in the arm housing groove 356 in this way, the disk stopper 35 is disposed substantially parallel to the bottom surface of the panel driving member 3, and the disk contact head 355 is disposed at the head initial position. The

  With the trigger lever 36 returning to a position close to the display panel 2 (see FIG. 3) and the disk contact head 355 returning to the initial head position (see FIG. 6), the display panel 2 and the panel driving member 3 are further rearward. The trigger lever 36 slides backward along with the panel drive member 3 while maintaining the position on the bottom surface of the panel drive member 3. Here, the slide movement in the same traveling direction as the panel drive member 3 attached to the panel drive member 3 is referred to as a fourth slide movement.

  In the fourth slide movement of the trigger lever 36, the state where the tip of the lever arm 362 of the trigger lever 36 is stored in the arm storage groove 356 of the disk stopper 35 is maintained, so that the disk contact head 355 of the disk stopper 35 is The head is held at the initial position. Therefore, the disc stopper 35 does not affect the backward sliding operation of the display panel 2 and the panel driving member 3, and the sliding operation is performed quickly.

  Thus, when the display panel 2 appears and disappears, the trigger lever 36 that slides as described above and the disk stopper 35 that moves up and down by the sliding movement of the trigger lever 36 constitutes a second erroneous disk insertion preventing means. . Then, the erroneous insertion of the disc 100 can be prevented by the second erroneous insertion prevention means with such a configuration. In such second disc erroneous insertion preventing means, the trigger lever 36 and the disc stopper 35 constitute a cam structure, the trigger lever 36 corresponds to the original clause, and the disc stopper 35 corresponds to the follower.

  As described above, according to the present embodiment, when the display panel 2 is housed, when the main body 1 is viewed from the front, as shown in FIG. The entrance of the disc erroneous insertion space S formed at the top of the display panel 2 is covered with the upper side frame member 24a of the upper end portion of the display panel 2. Therefore, it is possible to prevent the disc 100 from being erroneously inserted into the disc erroneous insertion space S.

  Further, as shown in FIG. 4, when the display panel 2 is moved in and out, the disk contact head 355 of the disk stopper 35 is lowered and disposed in the disk erroneous insertion space S. Is inserted, the disk contact head 355 contacts the disk 100. Therefore, erroneous insertion of the disc 100 into the disc erroneous insertion space S can be prevented.

  As described above, according to this embodiment, it is possible to prevent erroneous insertion of the disc 100 both when the display panel 2 is stored and when it is retracted, and the disc 100 can be easily and accurately inserted during operation. It can be inserted into a disc playback device. Therefore, it is possible to prevent damage to the disk 100 or the like due to erroneous insertion. In addition, since the erroneous disk insertion prevention mechanism of this embodiment can be realized with a simple configuration without greatly changing the configuration of the electronic device, it is possible to suppress the increase in size and cost of the device. Become.

  In the above embodiment, the case where the present invention is applied to an in-vehicle electronic device has been exemplified, but the present invention is also applicable to other electronic devices.

Further, the disc error insertion preventing mechanism according to the present invention is not limited to the configuration of the above-described embodiment, and may have other configurations.
