The stepping motor 202 can drive the slider 181 to move below the front surface portion 120 and displace (tilt) the front surface portion 120 with respect to the front surface of the main body portion 110. The control unit 140 can display a message on the display unit 131 provided in front of the front unit 120.

  11A and 11B are diagrams showing an example of table information stored in the memory 137 of the in-vehicle device 100, and FIG. 11C is a schematic side view of the in-vehicle system 1. FIG. 11D is a diagram showing the state of the front surface portion 120 stored in the memory 137 of the in-vehicle device 100. Note that the information illustrated in FIGS. 11A, 11 </ b> B, and 11 </ b> D may be stored in a memory provided in the control unit 140 instead of the memory 137.

  The table information in FIG. 11A includes “Tilt number” in the second mode (tilt instruction) of the tilt / eject button 132a (see FIG. 6) and “tilt” indicating the tilt of the front surface 120 with respect to the main body 110. The relationship between the angle “θ” (see FIG. 11C) and the “number of pulses” of pulses output from the control unit 140 to the stepping motor 202 is shown.

  Here, as shown in the table information of FIG. 11A, every time the tilt / eject button 132a is pressed once in the second mode, the tilt angle θ increases by 5 degrees. Therefore, the control unit 140 outputs a pulse signal to the stepping motor 202 in units of 10 pulses. One pulse is composed of one on / off (that is, one cycle), and the tilt angle θ per pulse corresponds to 0.5 degrees. Therefore, when the control unit 140 outputs a pulse signal to the stepping motor 202 in units of 10 pulses, the tilt angle θ of the front surface unit 120 increases every 5 degrees.

  Note that when the tilt / eject button 132a is pressed seven times in the second mode, the front surface 120 returns to the initial position. That is, the record of the number of times of pressing “6” in the table information in FIG. 11A becomes a record of the number of times of pressing “0”. In addition, it is desirable that the maximum tilt angle when the tilt / eject button 132a is in the second mode (when a tilt instruction is given) is an angle at which the CD insertion / extraction port 180 is not exposed. Note that the tilt angle is not limited to the values in this table.

  The table information in FIG. 11B is obtained when the state of the eject instruction or the like by pressing the tilt / eject button 132a (see FIG. 6) in the first mode (eject instruction) is “closed state” or “open state”. The tilt angle (see FIG. 11C) indicating the tilt of the front surface 120 with respect to the in-vehicle device main body 110 and the number of pulses of the pulse signal output from the control unit 140 to the stepping motor 202 are shown. As shown in the table information in FIG. 11B, the “tilt angle” in the “open state” is 60 degrees, and the “number of pulses” is 120. “Tilt angle” in the “closed state” is the tilt angle θ adjusted in the second mode, and “number of pulses” is not stored.

  When the front face 120 is closed and the tilt angle is θ, the tilt / eject button 132a is operated once in the first mode (that is, the open state of the front face 120 is instructed), and FIG. The front portion 120 operates so that the tilt angle θ is 60 degrees from the “tilt angle” of FIG. That is, the control unit 140 sets the “number of pulses” 120 in the “open state” in FIG. 11B and the angle θ (for example, 10 degrees) that is the “tilt angle” in the “closed state” in FIG. The number of pulses output to the stepping motor 202 is calculated from the corresponding “number of pulses” in FIG. 11A (for example, 20), and the calculated pulse is output to the stepping motor 202. As described above, one pulse is composed of one pulse on / off (that is, one cycle), and the tilt angle θ per pulse corresponds to 0.5 degrees. The controller 140 outputs a pulse signal to the stepping motor 202 in units of 10 pulses.

  When the front face 120 is in the open state and the tilt / eject button 132a is operated once in the first mode, the front face 120 returns to the tilt angle θ before the open state is instructed. That is, the control unit 140 sets the “number of pulses” 120 (for example, 20 degrees) corresponding to the “angle θ” (for example, 10 degrees) in FIG. ) And the number of pulses output to the stepping motor 202 is calculated, and the calculated pulse is output to the stepping motor 202. Note that the tilt angle (60 degrees in FIG. 11B) in the open state of the front surface portion 120 is not limited to the numerical value of this table, and may be an angle at which the CD insertion / extraction port 180 is exposed. Moreover, the state which the front-surface part 120 falls down completely may be sufficient.

  As shown in FIG. 11D, the memory 137 stores “current tilt angle” and “open / closed state”. The “current tilt angle” is the current tilt angle θ of the front surface portion 120, and is the current tilt angle θ of the front surface portion 120 adjusted by pressing the tilt / eject button 132a in the second mode. In the “open / closed state”, the open / closed state (open state or closed state) of the front surface portion 120 displaced by pressing the tilt / eject button 132a in the first mode is stored.

  FIG. 12 is a flowchart showing the control of the control unit 140 when the front surface part 120 is displaced. As shown in FIG. 11D, the memory 137 stores the tilt angle θ of the front surface 120 adjusted by pressing the tilt / eject button 132a in the second mode as the current tilt angle θ. At the same time, the open / closed state of the front surface portion 120 displaced by pressing the tilt / eject button 132a in the first mode is stored. When the control unit 140 detects that the user has operated the tilt / eject button 132a (see FIG. 6), the flow of FIG. 12 is started. The control unit 140 determines whether the USB memory 200 is attached to the external audio / video input unit 139 (Yes) or not (No) (step S10). The control unit 20 of the portable device 10 determines whether or not the USB memory 200 is mounted, and the control unit 20 transmits a signal indicating whether or not the USB memory 200 is mounted to the control unit 140. Thereby, the control unit 140 can determine whether or not the USB memory 200 is attached. When the external audio / video input unit 139 and the control unit 140 are connected without the control unit 20, the control unit 140 may directly determine whether the USB memory 200 is attached.

  If Yes in step S10, that is, if the control unit 140 determines that the USB memory 200 is attached to the external audio / video input unit 139, the control unit 140 cannot displace the front unit 120 on the display unit 131. Is displayed (step S11), and the process is terminated. That is, when the USB memory 200 is attached to the external audio / video input unit 139, the displacement of the front unit 120 is limited. In addition, instead of displaying a warning that displacement cannot be performed, the speaker 145 outputs a voice output or warning sound that the displacement cannot be performed, or instructs the user to remove the USB memory 200 from the external audio / video input unit 139. Display or audio output may be performed.

  In the case of No in step S10, that is, when the control unit 140 determines that the USB memory 200 is not attached to the external audio / video input unit 139, the control unit 140 determines whether or not it is a tilt instruction, that is, tilt / eject. It is determined from the operation mode of the button 132a whether it is a tilt command (second mode) or an eject command (first mode) (step S12). In the case of Yes in step S12, that is, when the control unit 140 determines that the operation of the tilt / eject button 132a by the user is a tilt instruction (second mode: for example, long press operation), the control unit 140 determines the tilt / eject button. The number of times 132a has been pressed in accordance with the tilt instruction (second mode) is counted (step S13). The control unit 140 reads the current tilt angle θ from the memory 137 (step S14). The memory 137 stores the current tilt angle of the front face 120 when the tilt / eject button 132a is displaced by an operation according to a tilt instruction (second mode). Information regarding the current tilt angle θ may be stored instead of the current tilt angle θ.

  Next, the control unit 140 shows the current tilt angle θ stored in the memory 137, the number of times the tilt / eject button 132a is counted in step S13, and the memory 137 shown in FIG. The tilt angle θ ′ after displacement is determined from the table, and the number of pulses output to the stepping motor 202 is determined from the current tilt angle θ of the front face 120 and the tilt angle θ ′ after displacement (step S15).

  Next, the control unit 140 outputs a pulse signal having the number of pulses determined in step S15 to the stepping motor 202 in order to obtain the tilt angle θ ′ after displacement of the front surface part 120 (step S18). The stepping motor 202 drives the slider 181 by an amount corresponding to the number of pulses of the pulse signal from the control unit 140. As a result, the front surface portion 120 is displaced to a predetermined tilt angle θ ′. The control unit 140 stores the tilt angle θ ′ as the current tilt angle θ in the memory 137 (step S17), and ends the process. That is, when the USB memory 200 is not attached to the external audio / video input unit 139, the number of times of pressing the tilt / eject button a with the tilt instruction (second mode) is determined based on the table shown in FIG. Thus, the front surface portion 120 can be displaced (tilted) with respect to the in-vehicle device main body portion 110.

  In the case of No in step S12, that is, when the control unit 140 determines that the operation of the tilt / eject button 132a by the user is an ejection instruction (first mode: for example, a short press operation), the control unit 140 It is determined from the memory 137 whether or not the front face 120 is in an open state (step S18). As shown in FIG. 11D, the memory 137 stores information indicating that the front surface 120 is in an open state or a closed state, and the initial value (the tilt / eject button 132a has never been displayed in the past). In the case where the operation according to the eject instruction is not performed, information indicating an open state) is stored.

  In the case of Yes in step S18, that is, when the control unit 140 determines that the front unit 120 is in the open state, the short pressing operation of the tilt / eject button 132a displaces the front unit 120 from the open state to the closed state. Instructions. The current tilt angle θ (the angle θ before the open state) is read, and the read current tilt angle θ and the tables shown in FIGS. 11A and 11B stored in the memory 137 are used. The number of pulses output to the stepping motor 202 is determined in order to return the front surface part 120 to the state before the open state (current tilt angle θ) (step S19).

  Next, the control unit 140 outputs a pulse signal having the number of pulses determined in step S19 to the stepping motor 202 in order to set the front surface part 120 to the current tilt angle θ (the angle θ before the opening state). Step S20). The stepping motor 202 drives the slider 181 by an amount corresponding to the number of pulses of the pulse signal from the control unit 140. As a result, the front surface portion 120 is displaced to the current tilt angle θ (angle θ before entering the open state). The control unit 140 stores information indicating that the front surface unit 120 is in the closed state in the memory 137 (step S21), and ends the process.

  In the case of No in step S18, that is, when the control unit 140 determines that the front unit 120 is not in the open state, the short press operation of the tilt / eject button 132a displaces the front unit 120 from the closed state to the open state. This is an instruction. To read the current tilt angle θ, and to use the read current tilt angle θ and the table shown in FIGS. 11A and 11B stored in the memory 137 to close the front face 120. The number of pulses output to the stepping motor 202 is determined (step S22).

  Next, the control unit 140 outputs a pulse signal having the number of pulses determined in step S22 to the stepping motor 202 in order to open the front surface part 120 (step S23). The stepping motor 202 drives the slider 181 by an amount corresponding to the number of pulses of the pulse signal from the control unit 140. Thereby, the front part 120 is displaced to an open state. The control unit 140 stores information indicating that the front surface unit 120 is in the open state in the memory 137 (step S24), and ends the process. That is, when the USB memory 200 is not attached to the external audio / video input unit 139, the tilt / eject button 132a is pressed according to the number of times of pressing in the eject instruction (second mode), as shown in FIGS. ) Can be displaced (tilted) with respect to the in-vehicle device main body 110 based on the table shown in FIG.

  According to the first embodiment, when the USB memory 200 (external device) is attached to the front surface part 120 as in step S10, the control unit 140 limits the displacement of the front surface part 120. As a result, the displacement of the front surface portion 120 can be limited while the USB memory 200 is attached. As a result, the front part 120 is not displaced when the USB memory 200 is mounted, and the USB memory 200 is present in the vicinity of the in-vehicle device main body 110 or the in-vehicle device 100 due to the displacement of the front part 120 (for example, an operator's hand or It is possible to suppress damage to the USB memory 200 and the in-vehicle device 100, injury to the operator, and the like.

  Further, the displacement from the closed state of the front surface 120 to the open state where the CD insertion / extraction port 180 on the front surface of the main body is exposed and the displacement from the closed state to the closed state are limited, and the tilt angle of the front surface 120 is finely adjusted. Can also be unrestricted. The front portion 120 is largely displaced from the open state to the closed state and from the closed state to the open state. Therefore, by restricting these displacements, damage to the USB memory 200 and the in-vehicle device 100, injury to the operator, and the like can be suppressed.

  Furthermore, the control unit 140 can also limit displacement to some tilt angles. For example, when the tilt angle is large, the USB memory 200 protrudes to the front. Therefore, when the tilt angle is larger than a certain value, by restricting the displacement of the front surface portion 120, damage to the USB memory 200 in-vehicle device 100, injury to the operator, and the like can be more effectively suppressed.

  Next, an example of operation when the USB memory 200 is attached to the external audio / video input unit 139 will be described. Referring to the flowchart of control unit 140 in FIG. 13, control unit 140 determines whether USB memory 200 is attached to external audio / video input unit 139 (step S30). In the case of Yes, the control unit 140 instructs the stepping motor 202 to displace the front surface part 120 to the initial position facing the front surface of the main body part 110 (step S32). In the case of No in step S30, the control unit 140 ends without displacing the front surface part 120. As shown in FIG. 13, when the USB memory 200 is attached, the control unit 140 sets the front surface part 120 as the initial position. The initial position is a state in which the USB memory 200 is at the backmost side, and thereby, damage to the USB memory 200 in-vehicle device 100, injury to the operator, and the like can be suppressed.

  A main body operation unit such as a CD insertion / extraction port 180 may be provided on the front surface of the main body unit 110. However, in the case of a configuration in which the main body operation unit is exposed by displacing the front surface part 120 from the front surface of the main body part 110, there are many opportunities to displace the front surface part 120 in particular. Therefore, it is more effective to limit the displacement of the front surface portion 120 when the USB memory is attached. In addition to the CD insertion / extraction port 180, the front surface of the main body 110 may be a DVD / storage card insertion / extraction port, operation buttons, or a combination thereof.

  The USB memory 200 may be provided on any surface of the front part 120. However, if the USB memory 200 can be mounted on the front surface of the front surface portion 120, mounting is easy. In this case, if the front surface portion 120 is displaced in a direction facing the front surface, the risk of damage to the USB memory 200 is further increased. Therefore, it is more effective to limit the displacement of the front surface portion when the USB memory 200 is mounted. Further, as described above, the USB memory 200 may be provided on the front surface of the main body 110. In this case, there is a risk that the USB memory 200 and the in-vehicle device 100 may be damaged if the front surface portion 120 is displaced in a direction facing the front surface. Therefore, it is effective to limit the displacement of the front surface portion 120 when the USB memory 200 is mounted.

  An external device that protrudes from the front surface of the front surface portion 120 when attached to the front surface portion 120 or protrudes from the front surface of the main body portion 110 when attached to the main body portion 110 is not limited to the USB memory 200, When mounted, such as a connector for connecting to the in-vehicle device 100, or a connector for connecting a device (for example, a mobile phone) communicating with the outside to the in-vehicle device 100, it protrudes from the entire front surface 120 or the front surface of the main body 110. Anything to do. However, the USB memory 200 particularly protrudes from the front surface 120 or the front surface of the main body 110 when mounted. Moreover, it is easily damaged by impact. Therefore, it is more effective to limit the displacement of the front surface portion 120 when the external device that protrudes when attached to the front surface portion 120 or the main body portion 110 is a portable memory such as the USB memory 200.

  As shown in step S <b> 11 of FIG. 12, the control unit 140 preferably displays a warning on the display unit 131 when limiting the displacement of the front surface unit 120. Thereby, even if the operator instructs the displacement of the front surface portion 120, it can be prevented that the front device 120 is misunderstood as a malfunction of the in-vehicle device 100 even if the front surface portion 120 is not displaced.

  As shown in FIG. 14, the front surface portion 120 may be displaced so that the front surface of the front surface portion 120 faces downward. In this case, there is a high possibility that the USB memory 200 is in contact with the lower surface 204, and the restriction on the displacement of the front surface 120 when the USB memory 200 is mounted is particularly effective.

  The first embodiment has been described by taking the in-vehicle device 100 as an example, but the present invention is not limited to the in-vehicle electronic device, and may be a home (home) electronic device. However, in the case of an in-vehicle electronic device, it is often mounted on a dashboard portion as shown in FIG. For this reason, there is a high risk that the operator contacts the USB memory 200 when operating the shift lever. Further, since the inside of the cockpit of the vehicle is a particularly narrow space and there is also vibration, there is a high possibility that the operator will contact the USB memory 200 or the like. Therefore, in the in-vehicle electronic device, it is particularly effective to limit the displacement of the front surface portion 120 when the USB memory 200 is attached.

  Moreover, although Example 1 demonstrated the example which the front-surface part 120 displaces, this invention is not restricted to this, The structure which the upper surface part of an electronic device displaces (stands up) may be sufficient. In the first embodiment, the example in which the portable device 10 is mounted on the front surface portion 120 has been described. However, the portable device 10 may not be mounted. In the first embodiment, an example in which the portable device 10 is a portable navigation device has been described. However, the present invention is not limited thereto, and may be a mobile phone with a navigation function, a portable terminal (PDA), or the like. Further, in the first embodiment, an example in which the mounting unit is the external audio / video input unit 139 has been described. However, the external audio / video input unit 139 is a mounting unit such as a side surface, a back surface, an upper surface, or a lower surface of the front surface 120. The structure provided in surface parts, such as the structure provided in a surface part, the front surface of a main-body part, etc. may be sufficient. Further, in the first embodiment, the example in which the mounting unit is the external audio / video input unit 139 has been described. However, the present invention is not limited to this, and when mounted, the mounting unit can be viewed from the front of the front unit 120 or the front of the main unit 110. What is necessary is just to be able to mount a protruding external device.
