  FIG. 4 is a diagram for explaining operation control of the projection display unit 300. 4A shows a processing flow executed by the control unit 331 of the projection display unit 300, and FIG. 4B shows a processing flow executed by the control unit 501 of the portable device 1.

  In the following description of the operation control, for convenience, the control unit 501 of the portable device 1 is referred to as a portable control unit 501, and the control unit 331 of the projection display unit 300 is referred to as a projection control unit 331.

  When the projection display unit 300 is not used in a state where the charging holder 2 is connected to a commercial power source, the standby switch 337 is normally turned off. Thereby, no power is supplied to the projection display unit 300, and the power consumption of the projection display unit 300 is zero. At this time, since power is supplied to the power supply unit 200, if the mobile device 1 is set in the charging holder 2, the mobile device 1 is charged.

  When an image held by the mobile device 1 is projected by the projection unit 300, the user sets the mobile device 1 on the charging holder 2 or places the mobile device 1 near the charging holder 2 so that the mobile device 1 and the charging holder are placed. 2 is connected by a communication cable 3. Then, the operation switch unit 337a is operated to turn on the standby switch 337.

  When the standby switch 337 is turned on and power is supplied to the power supply unit 336, the projection control unit 331 is activated. As a result, the projection display unit 300 enters a standby state.

  As shown in FIG. 4A, the projection control unit 331 monitors an activation signal from the mobile device 1 (S101).

  As shown in FIG. 4B, in the portable device 1, the portable control unit 501 monitors an operation for starting the projection display unit 300 (S201).

  When the user performs an activation operation of the projection display unit 300 using the operation unit 503 (S201: YES), the portable control unit 501 transmits an activation signal to the projection display unit 300 (S202).

  When the activation signal is transmitted to the projection control unit 331 (S101: YES), the projection control unit 331 performs a setup process for putting the projection display unit 300 into an operating state such as turning on the light source unit 311 (S102). . When the setup process is completed, an activation completion signal is transmitted to inform the mobile device 1 that activation has been completed (S103).

  When receiving the activation completion signal (S203: YES), the portable control unit 501 transmits the video signal of the image to be projected to the projection display unit 300 based on the user's transmission operation (S204).

  When receiving a video signal (S104: YES), the projection control unit 331 starts projection (S105). As described above, the video signal is output from the video signal processing unit 333 to the light modulation unit 315, and an image based on the video signal is projected onto the projection surface through the projection lens 320.

  Next, in the portable device 1, when the user performs an operation to end the driving (S205: YES), the portable control unit 501 stops the transmission of the video signal (S206), and gives a stop signal for stopping the driving. It transmits to the projection display unit 300 (S207).

  When the projection control unit 331 receives the stop signal (S106: YES), the projection control unit 331 performs a predetermined shutdown process such as turning off the light source unit 311 to shift the projection display unit 300 to the standby state (S107). When the shutdown process is completed, a stop completion signal is transmitted to inform the mobile device 1 that the operation has stopped (S108).

  Thereafter, in the standby state, the projection control unit 331 monitors the activation signal again (S101) if the standby switch 337 is not turned off based on the user's operation (S109: NO). During this time, if the standby switch 337 is turned off (S109: YES), the operation control ends.

  On the other hand, after receiving the stop signal (S208: YES), the portable control unit 501 monitors the activation operation of the projection display unit 300 again if the portable device 1 is not powered off (S209: NO) (S201). . During this time, if the power of the portable device 1 is turned off by the user's operation (S209: YES), the operation control ends.

  If communication with the projection display unit 300 is interrupted during transmission of the video signal from the portable device 1 due to the disconnection of the communication cable 3 or the like (S210: YES), the portable control unit 501 Transmission of the video signal is stopped (S211).

  For example, when the control signal input unit 334 and the control signal output unit 506 are connected via the communication cable 3, the input signal of a predetermined terminal of the connector constituting the control signal output unit 506 rises to a certain voltage level. A control signal input unit 334, a control signal output unit 506, and a portable control unit 501 are configured. The portable control unit 501 determines that the communication is interrupted when the input signal falls from the voltage level by disconnecting the communication cable 3.

  On the other hand, when the communication is cut off and the video signal is not received for a predetermined time (S110: YES), the projection control unit 331 executes a shutdown process (S111) and stops the operation. As a result, the projection display unit 300 enters a standby state.

  As described above, according to the present embodiment, it is possible to enlarge and project an image held by the mobile device 1 using the charging holder 2. Therefore, an image stored in the mobile device 1 can be easily viewed on a large screen without impairing the portability of the mobile device 1.

  Further, in the present embodiment, projection is possible only by carrying only the charging holder 2 together with the portable device, so that convenience for the user is enhanced. The charging holder is often carried along with the portable device. Therefore, the user can easily perform projection with the charging holder that is easily carried for charging at the same time.

  Also, for example, when a projector is built in a mobile phone, when a call is received during projection, the mobile phone fixed on a desk or the like is temporarily moved for a call. In this case, after the call is finished, setting work such as focus adjustment must be performed again, which is troublesome. In this regard, in the present embodiment, when the mobile device 1 is a mobile phone, it is only necessary to remove the mobile phone from the charging holder 2 if there is a call, and there is no need to move the charging holder 2 itself. Therefore, there is no need to redo the setting work as described above.

  Furthermore, according to the present embodiment, since the operation of the projection display unit 300 is performed using the operation unit 503 of the portable device 1, the number of operation units provided on the charging holder 2 side can be reduced. . Therefore, the charging holder 2 can be simplified.

  Further, according to the present embodiment, the standby switch 337 is arranged on the power supply line to the projection display unit 300, and the power supply unit 200 can be charged with the power supply unit 200 while the portable device 1 can be charged. Therefore, the power consumption of the charging holder 2 can be suppressed.

  Furthermore, according to the present embodiment, if the video signal is not normally received, the operation of the projection display unit 300 is automatically stopped, so that useless power consumption can be avoided.

  In the above embodiment, the control signal and the video signal are transmitted by the communication cable 3. However, as in the present modification, the control signal and the video signal may be transmitted by wireless communication. .

  The mobile device 1 and the projection display unit 300 are provided with wireless communication units 512 and 339, respectively. Other configurations are the same as those in the above embodiment.

  In the portable device 1, when the wireless communication is set by the user, the control unit 501 outputs a control signal related to the driving operation of the projection display unit 300 to the wireless communication unit 512. Further, the video signal processing unit 504 outputs the video signal to the wireless communication unit 512. The wireless communication unit 512 converts the control signal and the video signal into a wireless signal and transmits the wireless signal to the wireless communication unit 339 of the projection display unit 300. The wireless communication unit 339 converts the received wireless signal into a control signal and a video signal, and outputs them to the control unit 331 and the video signal processing unit 333, respectively.

FIG. 7 is a block diagram illustrating a configuration of a mobile device according to the third modification. In FIG. 7, solid arrows indicate signal lines, and broken arrows indicate power supply lines. A white arrow indicates a mixed line of signal and power.

  Instead of the configuration in which the control signal and the video signal are transmitted through the communication cable 3 as in the above embodiment, or the configuration in which the control signal and the video signal are transmitted through wireless communication as in the second modification, As in this modified example, a configuration in which a control signal and a video signal are transmitted using a power supply line may be employed.

  In the portable device 1, a superposition / separation unit 513 and a power / signal input / output unit 514 are arranged instead of the power input unit 508. In addition, the power supply unit 200 includes a superposition / separation unit 205 and a power / signal input / output unit 206 instead of the power output unit 204. The power / signal input / output unit 206 includes an output terminal unit 200 a, similar to the power output unit 204.

  The charging voltage generated by the voltage conversion unit 202 is supplied to the battery charging unit 508 and the power supply unit 511 through the superimposition / separation unit 205, the power source / signal input / output unit 206, the power source / signal input / output unit 514, and the superposition / separation unit 513. Is done.

  On the other hand, the control unit 501 outputs a control signal related to the operation of the projection display unit 300 to the superimposing / separating unit 513. Further, the video signal processing unit 504 outputs the video signal to the superimposing / separating unit 513. The superimposing / separating unit 513 modulates the input control signal and video signal, superimposes them on the power supply line, and transmits them to the superimposing / separating unit 205 through the power / signal input / output unit 514 and the power / signal input / output unit 206. . Superposition / separation section 205 separates the control signal and video signal superimposed on the power supply line, demodulates them, and outputs them to control section 331 and video signal processing section 333, respectively.

  According to the configuration of the present modification example, as in the configuration of the modification example 2, the work of connecting the communication cable 3 is not necessary, and the convenience for the user is improved.

  Note that this modification example can also be applied to the portable device of the modification example 1 described above.

<Others>
The embodiment of the present invention can be variously modified in addition to the above.

  For example, instead of the optical engine 310 shown in FIG. 2A, the optical engine 340 shown in FIG. 2B can be mounted on the charging holder 2.

  As shown in FIG. 2B, the optical engine 340 includes three light source units 341R, 341G, and 341B. The light source unit 341R includes an LED that emits R light. The light source unit 341G includes an LED that emits G light, and the light source unit 341B includes an LED that emits B light. Light is emitted from each of the light source units 341R, 341G, and 341B in a time division manner.

  The R light emitted from the light source unit 341R enters the dichroic mirror 343 through the lens 342R. The dichroic mirror 343 reflects B light and G light and transmits R light. The R light passes through the dichroic mirror 343 and enters the fly-eye lens array 346.

  The G light emitted from the light source unit 341G enters the dichroic mirror 344 through the lens 342G. The dichroic mirror 344 reflects G light and transmits B light. The G light is reflected by the dichroic mirror 344, further reflected by the dichroic mirror 343, and enters the fly-eye lens array 346.

  The B light emitted from the light source unit 341B is reflected by the mirror 345 through the lens 342B. Then, the light passes through the dichroic mirror 344, is further reflected by the dichroic mirror 343, and enters the fly-eye lens array 346.

  The fly-eye lens array 346 is composed of a pair of lenses, and each lens is composed of a large number of cells arranged in the shape of an eyelet. The light (R light, B light, G light) incident by these cells is divided. Each of the divided lights is superimposed on the DMD 349 by the lens action of the condenser lens 347 and the reflection at the mirror 348. Thereby, the light quantity distribution of the light irradiated to the DMD 349 is made uniform.

  DMD 349 includes micromirrors that are independently driven, and modulates R light, G light, and B light irradiated in time division based on a video signal. The modulated R light, G light, and B light are sequentially enlarged and projected onto the projection surface by the projection lens 320.

  Since the switching of the emission of the R light, G light, and B light is performed at a very high speed, the projected R light, G light, and B light are combined on the projection surface, and one for the user's eyes. It appears as a color image.

  Further, in the above embodiment, the operation unit for operating the projection display unit 300 is not provided in the charging holder 2, but such an operation unit may be provided in the charging holder 2.

  In this way, the projection display unit 300 can be operated even if communication with the portable device 1 is not possible. Thereby, even when the portable device 1 is not present, the charging holder 2 can be used alone as a projector, and images from other devices such as a personal computer can be projected. Therefore, the added value of the charging holder 2 can be increased.

  Further, instead of using the communication cable 3 as in the above embodiment, the portable device 1 is provided with an output terminal portion for video signals and the like, and the charging holder 2 is provided with a connector portion. The output terminal portion may be directly connected to the connector portion when set to. Further, in such a configuration, the standby switch 338 of the first modification may be turned on when the output terminal portion is connected to the connector portion.

  Furthermore, in the above-described embodiment, the portable device 1 is held by housing the back surface of the portable device 1 by the recess 101 provided in the cabinet 100. However, the present invention is not limited to this, and any holding mechanism may be provided in the cabinet 100 as long as the portable device 1 is held. Further, as in the above-described embodiment, the cabinet 100 may be provided with a holding mechanism that holds the portable device 1 in an upright manner instead of holding the portable device 1 so as to lie down.

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
