  Hereinafter, specific examples of the present invention will be described in detail with reference to examples and drawings. However, the embodiment described below exemplifies an in-vehicle electronic device for embodying the technical idea of the present invention, and is not intended to specify the present invention as the in-vehicle electronic device. The present invention is equally applicable to electronic devices of other embodiments included in the scope of claims.

  As shown in FIGS. 1 to 4, an in-vehicle electronic device 10 according to an embodiment of the present invention includes a housing 20, a mounting portion 30 for mounting an information storage medium provided in the housing 20, and a housing. Case front panel 40 forming the front surface of body 20, information storage medium insertion port 50 formed in case front panel 40, and information storage medium provided at one end of insertion port 50 to prevent removal And a front panel 70 slidably mounted on the front surface of the housing front panel 40 so as to be openable and closable. The in-vehicle electronic device 10 is incorporated in a free space of a console provided in the automobile so that the front panel 40 and the front panel 70 appear on the surface.

  The insertion slot 50 is formed in a slit shape so that, for example, an IC card 80, which is a card-like information storage medium, is attached to or detached from the attachment portion 30, and a concave portion 501 for pinching the IC card is formed in the center portion. Yes. The corner of the IC card 80 is rounded.

  The retaining mechanism 60 that forms the retaining means includes a slide member 601 that slides in the slit direction of the insertion port 50 on the back surface of the housing front panel 40 at the entrance of the insertion port 50, and a front surface of the housing that slides the slide member 601. And an operation knob 602 disposed on the surface of the panel 40. The movement range of the slide member 601 is retreated from the first position protruding from the insertion port 50 shown in FIGS. 1 to 6 and the insertion port 50 shown in FIGS. 7 to 10 by the guide groove 603 and the guide pin 604. It is set so as to be between the second position. The slide member 601 is biased so as to always take the first position where the insertion port 50 is closed by the spring 605 and has a function of preventing the slide member 601 from coming off.

  The front panel 70 is provided with a flat display surface 701, operation buttons 702, and the like. In the state where the front panel 70 is opened, the housing front panel 40 is opened to allow the IC card 80 to be attached and detached. The front panel 70 has the display surface 701 facing upward when the housing front panel 40 is open. On the other hand, when the front panel 70 is closed, an operation button 702 can be operated to display an image on the display surface 701.

  As shown in FIG. 6, the tip 606 of the slide member 601 abuts on the rear edge 801 of the IC card 80 mounted on the mounting portion 30 when the slide member 601 is in the first position. A notch 607 is formed in the surface. The notch 607 has a shape into which the rear edge 801 of the IC card 80 is inserted, and the slide member 601 is not obstructed from taking the second position by the IC card 80. The tip 606 is substantially integrated with the operation knob 602.

  As shown in FIGS. 3, 4, and 8, a position sensor 90 that detects that the slide member 601 is in the second position is provided on the housing 20 side. The position sensor 90 includes a switch 902 having a movable element 901 that operates by abutting the rear end 608 when the slide member 601 is in the second position. Here, the position sensor 90 may be a switch including a contact point that is mechanically opened and closed, or may be one using a change such as optical or magnetic.

  As shown in FIG. 11, the position sensor 90 has a control circuit 100 connected to its output side. An open / close drive circuit 110 that opens and closes the front panel 70 is connected to the output side of the control circuit 100 via a drive inhibition circuit 120. The opening / closing drive circuit 110 opens and closes the front panel 70 by an opening / closing operation by an operation unit (not shown). The drive prohibiting circuit 120 forming the prohibiting means prohibits the closing operation of the opening / closing drive circuit 110 by the control circuit 100 when the detection output of the position sensor 90 is obtained.

  Similarly, on the output side of the control circuit 100, an alarm drive circuit is provided with an alarm unit 130 that issues an alarm indicating that the IC card 80 is incompletely installed by voice from a speaker (not shown) or / and by displaying characters on the display surface 701. 140 is connected. This alarm drive circuit 140 is for causing the control circuit 100 to start an alarm operation of the alarm unit 130 when the detection output of the position sensor 90 is obtained. Here, the control circuit 100 controls alarm means including the alarm unit 130 and the alarm drive circuit 140 when the mode in which the in-vehicle electronic device 10 applies the IC card 80 is selected. Therefore, in the mode in which the IC card is not applied, the alarm means is not activated even if there is a detection output.

  Further, as shown in FIGS. 5 and 9, the insertion port 50 is provided with an inclined surface 502 at the other end of the slit facing the one end of the slit where the slide member 601 constituting the retaining mechanism 60 is located. The inclined surface 502 is formed at the other end of the slit in a shape that changes so that the longitudinal direction of the slit increases outward.

  Further, as shown in FIG. 12, when the slide member 601 is at the first position, the relationship between the size of the insertion slot 50 and the IC card 80 is as follows. The outermost length L1 is set to be at least larger than the width L2 of the IC guard 80.

  Next, the handling of mounting and dismounting of the IC card 80 of the in-vehicle electronic device 10 having the configuration according to the above-described embodiment will be described. When the IC card 80 is not used, the insertion slot 50 is blocked by the slide member 601 of the retaining mechanism 60. That is, the slide member 601 is in the first position where it protrudes into the insertion port 50 due to the biasing force of the spring 605.

  When the IC card 80 is mounted on the mounting unit 30 and used, the slide knob 601 is slid by operating the operation knob 602 leftward with the housing front panel 40 opened. By this operation, the slide member 601 slides from the first position to the second position against the biasing force of the spring 605. Therefore, the insertion port 50 is released from the state where it is blocked by the slide member 601.

  The user inserts the IC card 80 into the insertion slot 50 in a state where the slide member 601 is held at the second position by the operation knob 602. In this insertion, the front edge 802 of the IC card 80 is guided by the inclined surface 502 as shown in FIG. That is, the IC card 80 is guided to the insertion slot 50 when the corner of the front edge 802 hits the inclined surface 502. Then, the IC card 80 is completely attached to the attachment unit 30 by being pushed in.

  This complete mounting state is achieved by pushing the IC card 80 with the exposed portion since the central portion of the rear end of the IC card 80 is exposed in the recess 501. When the operation state of the operation knob 602 is released, the slide member 601 is returned to the first position by the spring 605.

  As shown in FIG. 12, when the user inserts the IC card 80 into the insertion slot 50 without touching the operation knob 602, the corner portion of the front edge 802 of the IC card 80 is inclined with respect to the tip 606. Located between the surface 502. When the IC card 80 is pushed in this state, the slide member 601 is moved from the first position to the second position. Therefore, even when the insertion port 50 is closed by the slide member 601, the user can mount the IC card 80 on the mounting unit 30 without operating the operation knob 602.

  In the case of the mounting shown in FIG. 12, even when the user operates the operation knob 602, the force to push the IC card 80 acts in the direction to slide the slide member 601 to the second position. The operation force of 602 can be reduced.

  When the slide member 601 reaches the first position, the corner portion of the rear edge 801 of the IC card 80 is inserted into the notch 607 formed at the tip portion thereof. Therefore, since the front end 606 of the slide member 601 is positioned in front of the rear edge 801 of the IC card 80, the IC card 80 is prevented from coming out of the mounting portion 30. That is, in a state where the IC card 80 is mounted, the insertion slot 80 is automatically blocked by the slide member 601 to prevent it from coming off.

  After the IC card 80 is mounted on the mounting unit 30, the front panel 70 can be closed and the video signal can be reproduced by operating the operation button 702.

  On the other hand, when the IC card 80 is detached from the mounting portion 30, the front panel 70 is opened, the operation knob 602 is operated, the slide member 601 is moved to the second position, and the second position is maintained. . Thus, by holding the slide member 601 in the second position, the IC card 80 is released from the state of being prevented from being detached. Therefore, the IC card 80 is detached from the mounting portion 30 by pinching and pulling the central portion exposed in the recess 501. Then, the IC card 80 is pulled out from the insertion slot 50 to achieve the detached state.

  After the IC card 80 is removed, the operation state in which the user holds and holds the operation knob 602 is released. Therefore, the slide member 601 automatically returns to the first position with the biasing force of the spring 605 when the operation state is released. In this state, the insertion port 50 is partially blocked by the slide member 601.

  If the mounted state is not perfect, as shown in FIGS. 9 and 10, the IC card 80 remains in the insertion path and protrudes from the insertion port 50 only partially. In this state, the tip 606 of the slide member 601 is in contact with the edge of the IC card 80 and is in the second position. Therefore, the rear end 608 of the slide member 601 pushes the actuator 901 of the position sensor 90 to operate the switch 902. As a result, the position sensor 90 detects that the IC card 80 is in the insertion path.

  As shown in FIG. 11, the detection output of the position sensor 90 is supplied to the control circuit 100. The control circuit 100 controls the drive prohibition circuit 120 based on the detection output and prohibits the opening / closing drive circuit 110 from closing the front panel 70. Therefore, even if the user performs an operation to close the front panel 70, the front panel 70 is not closed. At the same time, the control circuit 100 controls the alarm driving circuit 140 to activate the alarm unit 130. Accordingly, the alarm unit 130 issues an alarm indicating that the IC card 80 is in an incompletely mounted state.

  Thus, according to one embodiment of the present invention, when the IC card 80 is completely attached to the attachment portion 30, the rear edge 801 portion of the IC card 80 is inserted into the notch 607. Thus, the retaining state by the retaining mechanism 60 can be achieved. For this reason, the slide member 601 slides to the first position and closes the insertion port 50, so that the IC card 80 is prevented from coming out of the mounting portion 30 by the retaining mechanism 60.

  On the other hand, in a state where the IC card 80 is not completely attached and protrudes to the insertion slot 50, the tip 606 of the slide member 601 contacts the side edge of the IC card 80 and cannot slide to the first position. Then, the position sensor 90 detects that the slide member 601 is in the second position. The detection output of the position sensor 90 is used to prohibit the closing operation of the front panel 70 and to issue an alarm.

  Accordingly, since the user can know from the alarm that the IC card 80 is not completely installed, there is no erroneous operation of setting the reproduction operation of the stored information with the intention that the IC card is installed. Further, since the front panel 70 is not closed while the IC card 80 protrudes from the insertion slot 50, the IC card 80, the front panel 70, and the like are not damaged.

  In the above embodiment, the edge of the operation knob 602 is the same as the tip 606 that contacts the IC card 80. However, the operation knob 602 may be provided at a position away from the tip 606.

  In the above embodiment, when the IC card 80 is in the insertion path, the closing operation of the front panel 70 is prohibited and an alarm is issued. However, the present invention is not limited to this, and either one is not limited thereto. It may be only. Of course, in an electronic device which does not have the front panel 70 which opens and closes, it becomes only an alarm.

  In the above embodiment, the front panel 70 is opened and closed by the driving force of a motor or the like using the opening and closing drive circuit 110, but the present invention is not limited to this, and the opening and closing drive means for opening and closing is manually operated. It may have a mechanical configuration. In this case, the drive prohibition circuit 120 may be configured to control a mechanism that disables the mechanical closing mechanism.

  Further, in the above embodiment, the front panel 70 is provided on the front surface of the housing 20, but the present invention is not limited to this and is an openable panel provided on the upper surface, side surface, etc. of the housing 20. Also good.

  In the above embodiment, the IC card 80 is applied as the information storage medium. However, the present invention is not limited to this, and various types of information storage media in the form of cards and plates can be applied.
