<First Embodiment>
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an external configuration of an in-vehicle device 1 according to the present embodiment. The in-vehicle device 1 is mounted on a vehicle and has a function of reproducing audio and video data recorded on a CD (Compact Disc), a DVD (Digital Versatile Disk) and a card type device, and a navigation function, and is shown in FIG. Thus, the apparatus main body (vehicle-mounted apparatus main body) 10 accommodated in the storage space provided in the instrument panel of a vehicle and the display apparatus 11 provided in the front of this apparatus main body 10 are provided.

The display device 11 includes a liquid crystal display panel 12 on which a touch panel is arranged, a casing 13 in which the liquid crystal display panel 12 is fitted, and operation switches 14A and 14B provided on the casing 13. ing.
As shown in FIG. 2, a projection 15 is provided on the upper side of the display device 11, and the projection 15 is fitted in a guide groove 17 formed on the side wall 16 of the device body 10 so as to be movable in the vertical direction. At the same time, an extrusion mechanism 19 is connected to the lower portion of the side surface of the display device 11 via a pin 18, and this extrusion mechanism 19 is connected via the pin 18 using the driving force of a motor 38 (FIG. 4). The lower part of the display device 11 is pushed out in the horizontal direction, and as a result, the display device 11 opens and closes with respect to the device body 10 as shown in FIG. In this case, the guide groove 17 and the extrusion mechanism 19 constitute an opening / closing mechanism for the display device 11.

  The opening / closing instruction of the display device 11 is performed by operating the operation switches 14A and 14B provided on the housing 13 of the display device 11. Specifically, for example, when one of the operation switches (close key) 14A is pressed in the state of FIG. 3, the push-out mechanism 19 moves the lower part of the display device 11 toward the apparatus body 10 (right direction in the figure). Accordingly, the upper portion of the display device 11 is guided upward in the guide groove 17 through the protrusion 15, and as shown in FIG. 1, the display device 11 closes the front surface of the device body 10 (closed position). )

When the other operation switch (open key) 14B is pressed, the push-out mechanism 19 moves the lower part of the display device 11 to the opposite side (left direction in the figure) when the operation switch 14A is operated. Then, the upper portion of the display device 11 is guided in the downward direction of the guide groove 17 through the protrusion, and the display device 11 moves to a position where the front surface of the device body 10 is exposed (open position) as shown in FIG.
Further, the opening / closing instruction of the display device 11 can be performed not only by the operation of the operation switches 14A and 14B but also by the touch operation of the touch panel of the display device 11. Specifically, the display device 11 has an opening / closing instruction icon. Is displayed, the display device 11 opens and closes when the icon display area is pressed through the touch panel.

  As shown in FIG. 3, a card insertion slot 21 into which a card-type device 5 such as a PC (PCMCIA) card, a CF (CompactFlash), a micro drive, a mobile disk or the like is inserted, A discharge button 22 for discharging the card-type device 5 from the slot 21, a disk insertion slot 23 into which a disk-shaped recording medium such as a CD or a DVD is inserted, and a disk-type recording medium for discharging from the disk insertion slot 23 A discharge button 24 and the like are provided. As shown in FIG. 1, these insertion openings 21 and 23 are hidden behind the display device 11 when the display device 11 is closed. As shown in FIG. 3, the insertion ports 21 and 23 are opened to the outside when the display device 11 is opened. It is exposed and the insertion ports 21 and 23 can be accessed.

FIG. 4 is a block diagram showing the main configuration of the in-vehicle device 1.
The in-vehicle device 1 includes an MPU (connection control means) 30, and the MPU 30 centrally controls each part of the in-vehicle device 1. The MPU 30 is connected to a card interface (card I / F) 31. Card slot 32 is connected. The card slot 32 has a card insertion slot 21 through which a card-type device 5 conforming to TYPEI or II conforming to the PCMCIA standard is loaded.
The card type device 5 loaded in the card slot 32 is accessed by the MPU 30 via the card I / F 31, and the MPU 30 reads various data (music data etc.) recorded in the card type device 5, Write data to 5. The data written to the card type device 5 is, for example, compressed audio data obtained by performing a predetermined compression process on music data read from a CD.

  The MPU 30 is connected to a RAM 33 for temporarily storing data read from the card-type device 5 and data to be written, and a sub MPU 34 is connected. The sub MPU 34 includes a ROM that stores various data such as a control program, a RAM that temporarily stores data, and a CPU that performs various controls based on the program and data stored in the ROM. Then, display control of the display device 11 is performed.

The sub MPU 34 is connected to an insertion detection switch (insertion detecting means) 35 that detects that the card-type device 5 has been inserted into the card slot 32 and an operation unit 36 that functions as a user interface. Notifies the MPU 30 of information indicating the state of the insertion detection switch 35 and the operation of the operation unit 36. The operation unit 36 includes operation switches (close key, open key) 14A and 14B for instructing opening / closing of the display device 11 and a touch panel of the display device 11, and the sub MPU 34 is a predetermined region (for opening / closing instruction) of these operation switches and touch panel. When the icon display area is operated, the motor driver 37 connected to the sub MPU 34 is controlled.
Under the control of the sub MPU 34, the motor driver 37 generates a drive signal for a motor 38 that functions as a drive unit for the display device 11, and outputs the drive signal to the motor 38. The display device 11 is opened and closed by driving in reverse.

  In this in-vehicle device 1, when the card-type device 5 is inserted into the card insertion slot 21, the user inputs an opening instruction to the sub MPU 34 via the operation switch 14 </ b> B or the like, and the sub MPU 34 receives the motor based on the opening instruction. The motor 37 is driven by the driver 37, and the display device 11 is opened to a position where the card insertion slot 21 is exposed (FIG. 3), whereby the card type device 5 can be inserted into the card insertion slot 21.

  By the way, when the card-type device 5 is inserted and power is immediately supplied to the card-type device 5 to electrically connect the device body 10 and the card-type device 5, the card-type device 5 is removed immediately after insertion. The power supply to the card type device 5 is forcibly cut off, which is not preferable. Therefore, in the present embodiment, when the card-type device 5 is inserted into the card insertion slot 21, a connection control process for prohibiting electrical connection between the device body 10 and the card-type device 5 for a predetermined period is executed.

FIG. 5 is a flowchart showing this connection control processing. As a premise, it is assumed that the display device 11 is open to a position where the card insertion slot 21 is exposed.
First, the MPU 30 acquires the state of the insertion detection switch 35 via the sub MPU 34, determines whether or not the card type device 5 is inserted, and if the card type device 5 is not inserted (step S1: NO) The process is terminated. Even when this process is finished, the MPU 30 repeatedly executes this connection control process as long as the display device 11 is kept open, and continues to determine whether or not the card-type device 5 has been substantially inserted. It comes to judge.

  On the other hand, when the card-type device 5 is inserted (step S1: YES), the MPU 30 determines whether or not the card-type device 5 is removed based on the state of the insertion detection switch 35 (step S2). If 5 is removed (step S2: YES), this process ends. Thus, even if the card-type device 5 is removed immediately after insertion, the card-type device 5 is in an electrically disconnected state, so that the electrical connection between the device body 10 and the card-type device 5 is forcibly cut off. It will not be done.

  If the card-type device 5 has not been removed (step S2: NO), the MPU 30 determines whether or not a closing instruction for the display device 11 has been input (such as whether or not the operation switch 14A corresponding to the close key has been operated). If the closing instruction is not input (step S3: NO), the process proceeds to step S2. Accordingly, the MPU 30 waits until either of the card-type device 5 is removed (step S2: YES) or a closing instruction for the display device 11 is input (step S3: YES), and the card is satisfied. The mold apparatus 5 is maintained in an electrically disconnected state. For this reason, even if the card-type device 5 is removed, the electrical connection between the device body 10 and the card-type device 5 is not forcibly cut off.

On the other hand, when an instruction to close the display device 11 is input (step S3: YES), the MPU 30 starts the closing control of the display device 11 by driving the motor 38 by the motor driver 37 via the sub MPU 34 (step S4). . After starting the closing control of the display device 11, the MPU 30 supplies power to the card type device 5 loaded in the card slot 32 via the card I / F 31 and is electrically connected to the card type device 5 ( Step S5). More specifically, the MPU 30 can recognize / identify the card type device 5 by supplying power to the card type device 5 and electrically connecting the card type device 5 to perform recognition / identification processing of the card type device 5. On the condition that the device main body 10 and the card type device 5 are connected by bus, the state is maintained.
By connecting the apparatus main body 10 and the card-type device 5 in this way, the MPU 30 can store the data recorded in the card-type device 5 when instructed to reproduce the compressed music data recorded in the card-type device 5. Is read out for reproduction processing, and when data recording to the card-type device 5 is instructed, data to be recorded is written to the card-type device 5.

  However, in the process of step S5, when the recognition / identification of the card-type device 5 fails, the MPU 30 displays the display processing on the display device 11 so as to prompt the user to remove the card-type device 5. Various notification processes such as a sound emission process for emitting a notification sound indicating the above, a state in which the display device 11 is opened and opened, that is, an open drive process for facilitating removal of the card-type device 5 are appropriately executed. Therefore, if the card-type device 5 is not compatible with the in-vehicle device 1 or has failed, the device body 10 and the card-type device 5 are maintained in an electrically disconnected state.

As described above, according to the in-vehicle device 1 of the present embodiment, the device body 10 and the card-type device until the display device 11 starts the closing operation even when the card-type device 5 is inserted into the card insertion slot 21. 5 is maintained in an electrically disconnected state, even if the card-type device 5 is pulled out in a short time after insertion, the electrical connection between the device body 10 and the card-type device 5 is forcibly cut off. There is nothing.
In this case, since the closing operation of the display device 11 is started on the condition that the user gives an instruction to close the display device 11, the user confirms whether or not the inserted card-type device 5 is in error, After recognizing that there is no mistake and instructing the display device 11 to close, the device body 10 and the card-type device 5 can be electrically connected. For this reason, the apparatus main body 10 and the card-type apparatus 5 can be quickly brought into an electrically connected state when the possibility that the user pulls out the card-type apparatus 5 becomes low.

In the present embodiment, since the recognition / identification process of the card-type device 5 is started after the display device 11 starts the closing operation, the recognition / identification of the card-type device 5 is recognized until the display device 11 is almost completely closed. Processing can be terminated. In actual use, the in-vehicle device 1 is instructed to reproduce compressed music data recorded on the card-type device 5 with the display device 11 substantially closed. The card type device 5 can be accessed immediately.
Further, in the present embodiment, power is not supplied to the card-type device 5 until the display device 11 starts a closing operation. Therefore, the conventional vehicle-mounted device that supplies power as soon as the card-type device 5 is inserted. Power saving can be achieved as compared with the apparatus.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. The vehicle-mounted device according to the present embodiment is different from the vehicle-mounted device 1 according to the first embodiment in that the card-type device 5 is electrically connected to the card-type device 5 for a short time when the card-type device 5 is inserted. Since the other configuration is substantially the same as the vehicle-mounted device 1 according to the first embodiment, the same components are denoted by the same reference numerals, detailed description thereof is omitted, and different portions are described in detail.

FIG. 6 is a flowchart showing the connection control process.
First, the MPU 30 acquires the state of the insertion detection switch (insertion detection means) 35 via the sub MPU 34, determines whether or not the card type device 5 is inserted, and when the card type device 5 is not inserted. (Step S1A: NO), the process ends.

On the other hand, when the card-type device 5 is inserted (step S1A: YES), the MPU 30 accesses the card-type device 5 via the card I / F 31 and is based on information (card information) obtained from the card-type device 5. Then, recognition / identification processing of the card type device 5 is started (step S2A), and the following processing is executed according to the recognition / identification result of the card type device 5.
That is, when the recognition / identification of the card type device 5 fails (step S3: NO), the MPU 30 cuts off the power supply to the card type device 5 to release the bus connection with the card type device 5, and displays The device 11 is prohibited from accepting a closing instruction (step S4A). Therefore, when the card-type device 5 is not compatible with the in-vehicle device 1 or when the card-type device 5 is out of order, the device body 10 and the card-type device 5 are maintained in an electrically disconnected state, The display device 11 is prohibited from being closed. In this case, in order to prompt the user to remove the card-type device 5, various notification processes such as a display process for displaying that effect on the display device 11 and a sound emission process for emitting a notification sound indicating that effect are appropriately executed. You may make it do.

  On the other hand, when the card type device 5 is successfully recognized / identified (step S3: YES), the MPU 30 holds the card information obtained from the card type device 5 in the RAM 33 (step S5A), and then the card type device 5 The power supply to the device is cut off, and the bus connection between the device main body 10 and the card type device 5 is released (step S6A).

  Next, the MPU 30 determines whether or not the card-type device 5 has been removed based on the state of the insertion detection switch 35 (step S7A). If the card-type device 5 has been removed (step S7A: YES), the MPU 30 holds it in the RAM 33. After the card information is discarded (step S8A), this process ends. In this case, after the card type device 5 is recognized / identified, since the card type device 1 is in an electrically disconnected state, even if the card type device 5 is removed, the device main body 10 and the card type device 5 are not connected. The electrical connection is not forcibly cut off.

  On the other hand, if the card-type device 5 has not been removed (step S7A: NO), the MPU 30 has input a close instruction for the display device 11 (whether the operation switch 14A corresponding to the close key has been operated, etc.). (Step S9A), and when the close instruction is not input (step S9A: NO), the process proceeds to step S7A. Therefore, the MPU 30 waits until either of the card-type device 5 is removed (step S7A: YES) or a closing instruction for the display device 11 is input (step S9A: YES), and the device The main body 10 and the card-type device 5 are maintained in an electrically disconnected state. For this reason, even if the card-type device 5 is removed during this time, the electrical connection between the device body 10 and the card-type device 5 is not forcibly cut off.

  When an instruction to close the display device 11 is input (step S9A: YES), the MPU 30 starts the closing control of the display device 11 by driving the motor 38 by the motor driver 37 via the sub MPU 34 (step S10A). After starting the closing control of the display device 11, the MPU 30 supplies power to the card type device 5 loaded in the card slot 32 via the card I / F 31, and the bus between the device main body 10 and the card type device 5. The connection is restored (step S11A). In this case, since the MPU 30 holds the card information in the RAM 30, there is no need to newly read out the card information from the card type device 5, the bus connection is quickly restored, and the card type device 5 is immediately accessed. be able to.

  According to this embodiment, when the card-type device 5 is loaded, only the recognition / identification process of the card-type device 5 is performed, and the electrical connection between the device body 10 and the card-type device 5 is immediately released. Even if the card-type device 5 is removed after the recognition / identification process of the card-type device 5 is completed, the electrical connection between the device body 10 and the card-type device 5 is not forcibly cut off. In this case, since the recognition / identification process of the card-type device 5 is completed in a short time, even if the user tries to remove the card-type device 5 immediately after inserting the card-type device 5, the card before removing the card-type device 5 is used. The recognition / identification process of the mold device 5 has been completed, and the electrical connection between the device body 10 and the card device 5 is released before the card device 5 is removed. Therefore, when the card-type device 5 is removed, it is possible to sufficiently avoid the case where the electrical connection between the device body 10 and the card-type device 5 is interrupted.

In the present embodiment, the card information acquired during the recognition / identification process of the card-type device 5 is held, and after the display device 11 starts the closing operation, the device body 10 and the card-type device 5 are electrically connected again. Therefore, it is not necessary to newly read out the card information when electrically connecting again, and the reading of the data recorded in the card type device 5 can be started earlier.
Further, in this embodiment, when the recognition / identification of the card type device 5 fails, the closing operation of the display device 11 is prohibited, so that the user immediately takes out the card type device 5 that has failed in the recognition / identification and replaces it. be able to.
Further, in the present embodiment, power is not supplied to the card-type device 5 until the display device 11 starts a closing operation. Therefore, the conventional vehicle-mounted device that supplies power as soon as the card-type device 5 is inserted. Power saving can be achieved as compared with the apparatus.

  As mentioned above, although embodiment of the vehicle-mounted apparatus by this invention was described, this invention is not limited to this, A various change is possible. For example, in each of the above-described embodiments, the case where the device main body 10 and the card-type device 5 are electrically connected is illustrated almost simultaneously with the display device 11 starting the opening operation after the card-type device 5 is inserted. However, what is necessary is that the device main body 10 and the card-type device 5 only have to be electrically connected after the display device 1 starts the opening operation, and after the display device 11 is closed, the device main body 10 and the card-type device 5 May be electrically connected.
