<Procedure for attaching panel 3 to electronic device 2>
FIG. 16 is a side view showing a procedure for attaching the panel 3 to the connecting dock 40. FIG. 17 is a perspective view showing a part of the panel 3 as a cross section. 18 (a) and 18 (b) are cross-sectional views showing a procedure for attaching the panel 3 to the connecting dock, respectively.

When mounting the panel 3 on the connecting dock 40, first, as shown in FIGS. 16 and 18A, the guide recess 68 of the panel 3 is guided by the connecting dock 40 while the panel 3 is tilted and gripped. Engage with the protrusion 52. From this state, the panel 3 is rotated with the guide protrusion 52 as a rotation axis toward the front surface of the connecting dock 40 while the guide recess 68 is engaged with the guide protrusion 52.
First, the panel-side connector 66 comes close to the dock-side connector 51 in response to the rotation of the panel 3. Then, since the panel 3 is rotated around the guide protrusion 52 as a rotation axis from the inclined state, the panel 3 is sequentially connected to the dock side connector 51 from the terminal below the panel side connector, and the rotation progresses. Correspondingly, all the terminals of the panel side connector are connected to the dock side connector 51.
Here, as will be described later, the supply of electric power to the light receiving sensor 108 and the input / output of signals are performed by the electronic device 2 via the dock side connector 51 and the panel side connector 66. The power supply line for supplying power to the light receiving sensor 108 and the signal line for inputting / outputting a signal to / from the light receiving sensor 108 are located at the bottom of the terminals of the dock side connector 51. Conducts to the terminal. Hereinafter, among the terminals of the dock side connector 51, the terminal on which the power supply line for supplying power to the light receiving sensor 108 and the signal line for inputting / outputting the signal to / from the light receiving sensor 108 are conducted is referred to as ". It is expressed as "terminal for light receiving sensor on the dock side". Further, among the terminals of the panel side connector 66, the terminal on which the power supply line for supplying power to the light receiving sensor 108 and the signal line for inputting / outputting the signal to / from the light receiving sensor 108 are conductive is provided. Expressed as "panel side light receiving sensor terminal". Since the dock side light receiving sensor terminal and the panel side light receiving sensor terminal are provided at the bottom of the corresponding connectors, respectively, the dock side light receiving sensor terminal and the panel side light receiving sensor are provided according to the rotation of the panel. The connection with the terminal is made at the earliest stage.
Hereinafter, the connection between the terminal for the light receiving sensor on the dock side and the terminal for the light receiving sensor on the panel side is defined as "first electrical connection". In the state where the first electrical connection is established, the electronic device 2 can drive the light receiving sensor 108 and can acquire the detected value of the light receiving sensor 108.
Further, the connection between all the terminals of the dock side connector 51 and all the terminals of the panel side connector 66 is expressed as "second electrical connection" to distinguish it from "first electrical connection". In response to the rotation of the panel 3, the second electrical connection is made after the first electrical connection and before the physical connection described below. That is, when the panel 3 is attached to the electronic device 2, the first electrical connection, the second electrical connection, and the physical connection are in the order of the first electrical connection → the second electrical connection → the physical connection. Will be done.

At least after the terminal for the light receiving sensor on the dock side and the terminal for the light receiving sensor on the panel side are connected (= after the first electrical connection is made), when the rotation of the panel 3 further progresses, the panel 3 is engaged. The engaging claw 48 of the connecting dock 40 is elastically engaged with the hole 67, whereby the panel 3 is locked to the connecting dock 40. The state in which the panel 3 is locked to the connecting dock 40 by the engagement of the engaging claw 48 with the engaging hole 67 is the “state in which the electronic device 2 is mounted on the panel 3”.
Hereinafter, the operation when the engaging claw 48 is engaged with the engaging hole 67 when the panel 3 is attached will be described in detail.

19A to 19E are views used for explaining the operation when the engaging claw 48 of the connecting dock 40 is engaged with the engaging hole 67 of the panel 3.
19A to 19E show the engaging claw 48, the moving portion 101, the light emitting LED 105, and the opening 102, which are components on the connecting dock 40 side, and the engaging hole 67, which is a component on the panel 3 side. It is a figure which shows the positional relationship with the light receiving sensor 108, and the opening 107. 19A to 19E are views for the purpose of explaining the positional relationship of each member when the engaging claw 48 is engaged with the engaging hole 67, and for convenience of explanation, Each member is simplified and schematically shown.

FIG. 19A is a diagram showing the positional relationship of each component when the engaging claw 48 approaches the engaging hole 67 in response to the rotation of the panel 3.
As shown in FIG. 19A, the engaging claw 48 is provided with a guide portion 48a at its tip. The guide portion 48a is formed with an inclined portion 48b that expands to the left toward the rear.
As shown in FIG. 19A, the slide member 47 is in the first state when the engaging claws 48 are close to the engaging holes 67, but before they come into contact with each other. In this case, as described above, the opening 102 is closed by the moving portion 101, and the light emitted by the light emitting LED is blocked by the moving portion 101. Therefore, the light receiving sensor 108 does not receive the light emitted by the light emitting LED and does not detect the reception of infrared rays.

When the rotation of the panel 3 further progresses from the state of FIG. 19A, the front end portion of the inclined portion 48b comes into contact with the inner circumference of the engaging hole 67 at a certain point. FIG. 19B is a diagram showing a state in which the front end portion of the inclined portion 48b is in contact with the inner circumference of the engaging hole 67. In the state shown in FIG. 19B, the slide member 47 is in the first state, and the light receiving sensor 108 does not receive the light emitted by the light emitting LED 105 and does not detect the light reception of infrared rays.

When the rotation of the panel 3 further progresses from the state of FIG. 19B, the inclined portion 48b of the engaging claw 48 slides while being in contact with the inner circumference of the engaging hole 67. As the inclined portion 48b slides, the slide member 47 moves to the right against the urging force of the elastic member 100. The moving portion 101 of the slide member 47 also moves to the right in synchronization with the movement of the slide member 47 to the right due to the sliding of the inclined portion 48b. As the moving portion 101 moves to the right, the area where the moving portion 101 closes the opening 102 gradually shrinks. As the area where the moving portion 101 closes the opening 102 is reduced, the light emitted by the light emitting LED 105 begins to be output to the outside of the front cover 41 through the opening 102, and in response to this, the light receiving sensor 108 emits light. The light emitted by the LED 105 begins to be received. The light receiving intensity of the light receiving sensor 108 gradually increases as the moving unit 101 moves to the right. FIG. 19C is a diagram showing a state in which the central portion of the inclined portion 48b of the engaging claw 48 is in contact with the inner circumference of the engaging hole 67.

When the rotation of the panel 3 further progresses from the state of FIG. 19C, the rear end portion of the inclined portion 48b comes into contact with the inner circumference of the engaging hole 67. FIG. 19D is a diagram showing a state in which the rear end portion of the inclined portion 48b is in contact with the inner circumference of the engaging hole 67. In the state of FIG. 19D, the moving portion 101 is located at a position deviated from the position of the opening 102. In the state of FIG. 19D, the light receiving sensor 108 is in a state of receiving the light emitted by the light emitting LED 105, and the light receiving intensity of the light receiving sensor 108 is at or near the maximum.

As the rotation of the panel 3 further progresses from the state of FIG. 19D, the rear end portion of the inclined portion 48b exceeds the front end portion of the inner circumference of the engaging hole 67 toward the front. In response to this, the engaging claw 48 is elastically engaged with the engaging hole 67 by the urging force of the elastic member 100. FIG. 19E is a diagram showing a state in which the engaging claw 48 is engaged with the engaging hole 67. Further, FIG. 20 is a top view of the connecting dock 40 and the panel 3 in a state where the engaging claw 48 is engaged with the engaging hole 67, with a part of the connecting dock 40 as a cross-sectional view.
When the engaging claw 48 is engaged with the engaging hole 67, the slide member 47 is in the first state as shown in FIG. Therefore, the light emitted by the light emitting LED 105 is shielded by the moving portion 101 and is not output to the outside of the front cover 41. Therefore, the light receiving sensor 108 is in a state of not receiving the light emitted by the light emitting LED 105.

The engagement of the engaging claw 48 with the engaging hole 67 locks the panel 3 with respect to the connecting dock 40. As a result, the attachment of the panel 3 to the electronic device 2 is completed, and the panel 3 is attached to the electronic device 2.
Hereinafter, a state in which the engaging claw 48 is engaged with the engaging hole 67 and the panel 3 is locked with respect to the electronic device 2 is defined as “physical connection”.

As described above, the user grips the panel 3, engages the guide recess 68 of the panel 3 with the guide protrusion 52 of the connecting dock 40, and then rotates the panel 3, thereby performing the electronic device 2 The panel 3 can be attached to the.

<Procedure for removing panel 3 from electronic device 2>
When the panel 3 is removed from the electronic device 2, the user pushes the pushing portion 49 to bring the slide member 47 into the second state or a state close to the second state.

When the slide member 47 is in the second state, the engagement between the engagement hole 67 and the engagement claw 48 is released.

Next, the user continues the pushing operation of the pushing portion 49 while continuing the pushing operation of the pushing portion 49 until at least the engaging hole 67 crosses the rear end of the inclined portion of the engaging claw 48 toward the front, and the guide protrusion 52 Is used as a rotation axis, and the panel 3 is rotated toward the front side. In response to the rotation of the panel 3, the panel 3 is separated from the electronic device 2 in a state where the engagement hole 67 and the engagement claw 48 are disengaged. Further, as the panel 3 rotates, the connection between the terminal of the dock-side connector 51 and the terminal of the panel-side connector 66 is gradually released from the terminal located above to the terminal located below. To go. When the rotation of the panel 3 progresses and all the terminals of the dock-side connector 51 and all the terminals of the panel-side connector 66 are disconnected, the panel 3 can be removed from the electronic device 2. The user removes the panel 3 from the electronic device 2 by lifting the panel 3 in a predetermined direction and disengaging the guide recess 68 of the panel 3 from the guide protrusion 52 of the connecting dock 40. As described above, the removal of the panel 3 from the electronic device 2 is completed.
When the panel 3 is removed from the electronic device 2, the physical connection, the first electrical connection, and the second electrical connection are disconnected in the order of physical connection → second electrical connection → first electrical connection. ..

As described above, the user can remove the panel 3 from the electronic device 2 by a simple operation of pushing the pushing unit 49 and rotating the panel 3 in a predetermined direction.

Next, the operation of the electronic device 2 when the panel 3 is attached to the electronic device 2 and when the panel 3 is removed from the electronic device 2 will be sequentially described.

<When attaching the panel 3 to the electronic device 2>
The flowchart FA of FIG. 23 is a flowchart showing a process executed by the electronic device 2 according to the attachment of the panel 3 to the electronic device 2. At the start of the flowchart FA, the panel 3 is not attached to the electronic device 2.

As shown in the flowchart FA of FIG. 23, the device control unit 120 of the electronic device 2 monitors whether or not the first electrical connection has been made based on the input from the connection detection circuit 122 (step SA1). As described above, when the user performs the work of attaching the panel 3 to the electronic device 2, the first electrical connection is made prior to the second electrical connection and the physical connection. Therefore, by detecting the first electrical connection, it is possible to detect that the user may be performing the work of attaching the panel 3 to the electronic device 2.

When it is detected that the first electrical connection has been made (step SA1: YES), the device control unit 120 determines that the first electrical connection is for the first period or longer based on the input from the connection detection circuit 122. During that time, it is determined whether or not it has continued (step SA2). Here, when the user intentionally attaches the panel 3 to the electronic device 2, the first electrical connection continues for a certain period or more. On the other hand, when the terminal of the dock side connector 51 and the terminal of the panel side connector 66 are accidentally connected, the first electrical connection is immediately disconnected without continuing for a certain period of time or longer. Is assumed. In this case, the panel 3 is not attached to the electronic device 2. Based on this, in step SA2, the device control unit 120 attaches the panel 3 to the electronic device 2 by determining whether or not the first electrical connection has been continued for the first period or longer. It is determined whether or not there is a possibility of being damaged. The first period is an appropriate value considering that it is a period used for determining whether or not the panel 3 may be attached to the electronic device 2. Further, it is assumed that the first period is required from the first electrical connection to the physical connection when the user attaches the panel 3 to the electronic device 2 by a normal method. The time is sufficiently shorter than the period.
In the present embodiment, the first period is "0.5 seconds".

If the first electrical connection is not continued for the first period or longer (step SA2: NO), the device control unit 120 returns the processing procedure to step SA1 without executing the processing of step SA3 or lower. ..

When the first electrical connection is continued for the first period or more (step SA2: YES), the device control unit 120 controls the sensor control circuit 123 and starts driving the light receiving sensor 108 (step SA3). .. In response to the drive of the light receiving sensor 108, the light receiving sensor 108 starts detecting the light reception and outputting the detected value according to the light receiving state.
As described above, in the state where the first electrical connection is established, the dock side light receiving sensor terminal and the panel side light receiving sensor terminal are at least connected, so that the device control unit 120 is a sensor control circuit. It can drive 123 and acquire the detected value of the light receiving sensor 108.

Next, the device control unit 120 turns on the power of the light emitting LED 105, controls the LED control circuit 124, and drives the light emitting LED 105 (step SA4). In response to the drive of the light emitting LED 105, the light emitting LED 105 emits infrared light.

Next, the device control unit 120 starts acquiring the detected value of the light receiving sensor 108 based on the input from the sensor control circuit 123 (step SA5).
Here, the timing at which the process of step SA5 is executed is the timing at which the first period (“0.5 seconds” in the present embodiment) elapses after the first electrical connection is detected, and is physical. No physical connection is made. Therefore, the slide member 47 is in the first state, and the light emitted by the light emitting LED 105 is shielded by the moving portion 101.

Next, the device control unit 120 monitors whether or not the first electrical connection has been disconnected (step SA6), and monitors whether or not the physical connection has been established (step SA7).

In step SA7, the device control unit 120 detects that the physical connection has been established by the following method.
That is, the device control unit 120 monitors whether or not the light receiving sensor 108 has detected infrared light reception based on the detection value of the light receiving sensor 108 input from the sensor control circuit 123. At that time, the device control unit 120 calculates the light receiving intensity of the light received by the light receiving sensor 108 based on the detection value of the light receiving sensor 108, and when the light receiving intensity exceeds the first threshold value, the light receiving sensor 108 receives light. Is determined to have been detected. The first threshold value is emitted by the light emitting LED 105 in response to the state in which the rear end portion of the inclined portion 48b of the engaging claw 48 is in contact with the inner circumference of the engaging hole 67 (the state shown in FIG. 19D). The light receiving intensity of the light receiving sensor 108 that receives light is set in advance to a value that exceeds the first threshold value. By setting the first threshold value to such a value, the device control unit 120 detects that the light receiving intensity of the light receiving sensor 108 exceeds the first threshold value, thereby detecting the rear end of the inclined portion 48b of the engaging claw 48. It is possible to accurately detect that the portion is in contact with the inner circumference of the engaging hole 67. As described above, when the rear end of the inclined portion 48b of the engaging claw 48 is in contact with the inner circumference of the engaging hole 67 (the state shown in FIG. 19D), the light emitted by the light emitting LED 105 is emitted. It is not shielded by the moving unit 101.

Next, the device control unit 120 monitors whether or not the light receiving intensity of the light receiving sensor 108 is below the second threshold value (second threshold value <first threshold value). The second threshold value is such that the light receiving intensity of the light receiving sensor 108 falls below the second threshold value in response to the state in which the engaging claw 48 is engaged with the engaging hole 67 (the state shown in FIG. 19E). Value is set. By setting the second threshold value to such a value, the device control unit 120 detects that the light receiving intensity of the light receiving sensor 108 is lower than the second threshold value, so that the engaging claw 48 is placed in the engaging hole 67. It is possible to accurately detect the engagement. As described above, when the engaging claw 48 is engaged with the engaging hole 67 (the state shown in FIG. 19E), the light emitted by the light emitting LED 105 is shielded by the moving portion 101.

Further, when the device control unit 120 detects that the light receiving intensity of the light receiving sensor 108 is below the second threshold value, the device control unit 120 determines whether or not the second electrical connection is established. When the second electrical connection is established, the reason why the light receiving intensity of the light receiving sensor 108 is below the second threshold value is that the engaging claw 48 is properly engaged with the engaging hole 67, so that the device is controlled. The unit 120 determines that the physical connection has been established (step SA7: YES). As described above, when the panel 3 is attached to the electronic device 2, the physical connection is made after the second electrical connection. Therefore, when the physical connection is established, the second electrical connection is always established. It is in a state.
On the other hand, when the second electrical connection is not established, the reason why the light receiving sensor 108 falls below the second threshold value is assumed to be as follows. That is, the touch panel 61 is rotated in the direction opposite to the direction toward the electronic device 2, and the rear end portion of the inclined portion 48b of the engaging claw 48 is in contact with the inner circumference of the engaging hole 67 (state of FIG. 19D). ), The engaging claw 48 is not in contact with the engaging hole 67 (the state shown in FIG. 19A), and the moving portion 101 shields the light emitted by the light emitting LED 105 accordingly. It is assumed that the reason is that. Based on this, even if the light receiving intensity of the light receiving sensor 108 is lower than the second threshold value, if the second electrical connection is not established, the device control unit 120 has established the physical connection. It is determined that there is no such (step SA7: NO).

As described above, in step SA7, the device control unit 120 changes the light receiving state of the light receiving sensor 108 from "a state in which no light reception is detected" → "a state in which light reception is detected" → "a state in which no light reception is detected". After changing to (after changing in a predetermined pattern), when the second electrical connection is established, it is detected that the physical connection is established. Due to such a configuration, when the device 3 is attached to the electronic device 2, the moving unit 101 moves according to the rotation of the panel 3, and the light emitted by the light emitting LED 105 by the moving unit 101 is predetermined. Given the structural property of being shielded by aspects, the establishment of physical connections can be appropriately detected.

If the first electrical connection is disconnected (step SA6: YES) without establishing a physical connection (step SA7: NO), the device control unit 120 returns the processing procedure to step SA1. In the following cases, it is assumed that the first electrical connection is disconnected without establishing a physical connection. That is, the user discontinues the attachment of the panel 3 to the electronic device 2 and disengages the guide recess 68 of the panel 3 from the guide protrusion 52 of the connecting dock 40 without establishing a physical connection, and electronically. This is a case where the panel 3 is separated from the device 2.

If the physical connection is established (step SA7: YES) without disconnecting the first electrical connection (step SA6: NO), the device control unit 120 executes the first process at the time of mounting (step SA8). ..
The first process at the time of mounting is predetermined as a process to be executed on the electronic device 2 side when the panel 3 is physically connected to the electronic device 2.
The first process at the time of mounting includes, for example, a process of supplying electric power required for a control circuit for controlling the panel 3 and other components, and starting a program necessary for performing an operation using the panel 3. And initial processing is included.
Further, the first process at the time of mounting includes a process of adjusting the volume of the sound output by the sound output circuit 125 via the speaker. The adjusted volume is set to a level low enough not to surprise humans when they hear the voice. The process is executed for the following purposes. That is, the audio output by the electronic device 2 becomes possible according to the attachment of the panel 3 to the electronic device 2. Then, when the electronic device 2 outputs the voice, the process is executed in order to prevent the voice from being output at a loud volume contrary to the intention of the user.

Next, the device control unit 120 executes the second process at the time of mounting (step SA9).
In the second mounting process, the device control unit 120 controls the power supply circuit 121 to supply power to the power supply circuit of the panel 3 via the connector, and supplies power to the components necessary for starting the panel 3. Includes processing to do. Further, in the second mounting process, the device control unit 120 (including a circuit controlled by the device control unit 120) communicates with the panel control unit 150, outputs a control signal to the panel control unit 150, and displays the panel. Includes the process of activating 3. Further, the second process at the time of mounting includes a process in which the device control unit 120 communicates with the panel control unit 150, outputs a control signal to the panel control unit 150, and controls the panel 3.
By executing the second process at the time of mounting, the panel 3 is activated, the user can input instructions to the touch panel 61, and information can be displayed on the touch panel 61.

The first processing at the time of mounting and the second processing at the time of mounting correspond to "predetermined processing".

As described above, in the present embodiment, the device control unit 120 activates the panel 3 only after the physical connection is established, and then executes the process requiring communication with the panel control unit 150. Here, the state in which the physical connection is established is the state in which the second connection state is established and the panel 3 is locked with respect to the electronic device 2. Therefore, unless the engagement between the engagement hole 67 and the engagement claw 48 is released and the lock of the panel 3 with respect to the electronic device 2 is released, the second connection state (the state in which all the terminals are connected) is released. Not done. Based on this, the device control unit 120 executes a process that requires communication with the panel control unit 150 only after the physical connection is established, so that the second connection state is canceled during the communication and an error occurs. Is prevented.

<When removing the panel 3 from the electronic device 2>
The flowchart FB of FIG. 24 is a flowchart showing a process executed by the electronic device 2 in response to the removal of the panel 3 from the electronic device 2. At the start of the flowchart FB, the panel 3 is attached to the electronic device 2.

As shown in the flowchart FB of FIG. 24, the device control unit 120 of the electronic device 2 monitors whether or not the light receiving sensor 108 has detected the light reception based on the input from the sensor control circuit 123 (step SB1).
In step SB1, the device control unit 120 calculates the light receiving intensity of the light received by the light receiving sensor 108 based on the detected value of the light receiving sensor 108, and when the light receiving intensity exceeds the third threshold value, the light receiving sensor 108 performs. It is determined that the received light is detected. The third threshold is the light emitted by the light emitting LED 105 in response to the user pushing the pushing unit 49 to bring the slide member 47 into the second state (including a state close to the second state). The light receiving intensity of the light receiving sensor 108 that receives light is set in advance to a value that exceeds the third threshold value. By setting the third threshold value to such a value, the device control unit 120 detects that the light receiving intensity of the light receiving sensor 108 exceeds the third threshold value, so that the user pushes the pushing unit 49. Therefore, it can be accurately detected that the slide member 47 is in the second state. As described above, when removing the panel 3 from the electronic device 2, the user needs to push the pushing unit 49 to put the slide member 47 in the second state.

In step SB1, the device control unit 120 has changed the light receiving state of the light receiving sensor 108 from "a state in which no light reception has been detected" to "a state in which light reception has been detected" (changed in a predetermined pattern). By detecting, it is detected that the physical connection has been disconnected. Due to such a configuration, in the device control unit 120, when the panel 3 is removed from the electronic device 2, the moving unit 101 moves in response to the pushing operation of the pushing unit 49 by the user, and the moving unit 101 causes the light emitting LED 105 to move. Based on the structural property that the emitted light is shielded in a predetermined manner, the disconnection of the physical connection can be appropriately detected.

When it is determined that the light receiving sensor 108 has detected the light reception (step SB1: YES), the device control unit 120 executes the first process (first process) at the time of removal (step SB2).
In the first removal process, the device control unit 120 (including a circuit controlled by the device control unit 120) communicates with the panel control unit 150, outputs a control signal to the panel control unit 150, and displays the panel 3 Includes the process of shutting down. The panel control unit 150 executes software-like shutdown and hardware-like shutdown in response to the input of the control signal. When the panel 3 is shut down, the display of information by the display panel 3 and the acceptance of input by the display panel 3 are stopped.
Further, the device control unit 120 controls the power supply circuit 121 to stop the supply of unnecessary power to the panel 3. However, the power supply to the light receiving sensor 108 and the communicable state of the light receiving sensor 108 and the sensor control circuit 123 are maintained.

Here, when the user pushes the pushing unit 49, it is assumed that the panel 3 is subsequently removed from the electronic device 2. Based on this, when the device control unit 120 detects the push operation of the push unit 49 by the user, it communicates with the panel control unit 150 and shuts down the panel 3, so that the following can be achieved. Become. That is, when the second electrical connection is established and normal communication with the panel control unit 150 is possible, the panel 3 is shut down, and thereafter, with the panel control unit 150. It is possible to build a state where communication does not occur. Thereby, for example, it is possible to accurately prevent the panel 3 from being removed from the electronic device 2 and an error occurring during communication between the device control unit 120 and the panel control unit 150.

After executing the first process at the time of removal, the device control unit 120 monitors whether or not the second electrical connection is disconnected based on the input from the connection detection circuit 122 (step SB3).
As described above, when the panel 3 is removed from the electronic device 2, the user pushes the pushing portion 49 to release the engagement between the engaging claw 48 and the engaging hole 67, and then pushes the panel 3. , Rotates in the direction opposite to the direction toward the electronic device 2. Then, in response to the rotation of the panel 3, the second electrical connection is released prior to the release of the first electrical connection. Based on this, in step SB3, the device control unit 120 detects that the user has rotated the panel 3 in order to remove the panel 3 by detecting that the second electrical connection has been disconnected. To do.

When it is detected that the second electrical connection has been disconnected (step SB3: YES), the device control unit 120 executes the second process at the time of removal (step SB4).
The second process at the time of removal includes a process of shifting the electronic device 2 to the hibernation state. In the hibernation state, the power supply to the circuit related to the control of the panel 3 and other components is stopped, the program related to the control of the panel 3 is unloaded, the assignment of the task to the CPU is stopped, and the power consumption is consumed. Is in a suppressed state. In particular, the second process at the time of removal includes a process of muting the sound output by the sound output circuit 125 through the speaker. By this process, the panel 3 is removed from the electronic device 2, and it is ensured that the sound is output from the electronic device 2 in a state where the user does not use the electronic device 2 and the user cannot input instructions. Can be prevented.
After the second electrical connection is released, the second process at the time of installation is executed, so that the electronic device 2 is removed from the panel 3 from the electronic device 2 and the electronic device 2 is not used. It is possible to effectively prevent unnecessary processing from being executed and the electronic device 2 from consuming unnecessary power.

As described above, the vehicle car navigation system 1 (electronic device system) according to the present embodiment includes an electronic device 2 and a panel 3 that can be attached to and detached from the electronic device 2. The panel 3 includes a panel-side connector 66 used for electrical connection with the electronic device 2 and a panel-side connection portion 106 used for physical connection with the electronic device 2. The electronic device 2 has a dock-side connector 51 (device-side connector) that is electrically connected to the panel-side connector 66 and a panel for the electronic device 2 according to the operation in which the panel 3 is attached to the electronic device 2. After the electrical connection between the panel side connector 66 and the dock side connector 51 is made according to the operation in which 3 is mounted, the device side connection part 44 physically connected to the panel side connection part 106 and the panel side. After detecting the electrical connection between the connector 66 and the dock side connector 51, when the physical connection between the panel side connection unit 106 and the device side connection unit 44 is detected, the device control unit 120 (which executes a predetermined process) Control unit) and.
According to this configuration, the device control unit 120 determines when the panel is attached to the electronic device 2 after both the electrical connection and the physical connection between the electronic device 2 and the panel 3 are established. Execute the process. Therefore, in a state where the physical connection is not established and the electrical connection may be disconnected, a process that can be normally executed only when the electrical connection is established is executed, and an error occurs. Can be prevented. As a result, the device control unit 120 can properly attach the panel to the electronic device 2.

Further, in the present embodiment, the panel 3 includes a light receiving sensor 108 (light receiving unit) for detecting light reception. The electronic device 2 includes a light emitting LED 105 (light emitting unit) provided at a position facing the light receiving sensor 108 when the panel 3 is mounted on the electronic device 2.
