  However, the conventional image storage device has the following problems. That is, in this image storage device, it is possible to execute a storage process of image data stored in a memory card by inserting a card memory (memory card) removed from a digital camera or the like into a card slot. In this case, since today's memory card is very small, it is difficult to visually confirm whether or not a memory card is inserted in the card slot. Therefore, there is a risk that the power of the image storage device will be cut off while the memory card in which image data storage processing and the like have been completed is mounted in the card slot of the image storage device, and the memory card will be forgotten to be returned to the digital camera. As a result, a digital camera without a memory card may be carried and the user may notice that the memory card is not installed at the time of shooting.

  The present invention has been made in view of such problems, and a main object of the present invention is to provide a television that can avoid forgetting to remove a storage element connected to a connection portion.

  In order to achieve the above object, a television according to the present invention includes a connection unit to which a storage element can be connected, a detection unit for detecting whether or not the storage element is connected, and an operation unit having at least an operation switch that can be turned off. Image data stored in the storage element connected to the connection unit, and a control unit that controls the power supply unit to shut off the power according to a predetermined procedure when the power-off operation is performed. The control unit is configured to be able to display an image based on the information, and the control unit notifies that the storage element is connected when the detection unit detects the connection of the storage element during the power-off operation. The power supply is shut off according to the procedure of

  In this television, when the connection of the storage element is detected by the detection unit during the power-off operation, the control unit notifies that the storage element is connected and shuts off the power according to a predetermined procedure. Therefore, according to this television, even if a user who forgot to leave the memory element in the connection portion tries to shut off the power (or set the timer off operation), the memory element is still installed. It can be surely recognized that there is. As a result, since the user can remove the storage element from the connection portion and attach it to, for example, a digital camera, it is possible to avoid a situation in which shooting cannot be performed by carrying a digital camera with no storage element attached. Become.

  In the television according to the present invention, the control unit determines that the power-off operation has been performed when either the power switch or the timer-off setting switch is operated in the television.

  In this television, the control unit determines that the power-off operation has been performed when either the power switch or the timer-off setting switch is operated. Therefore, according to this television, it is possible to reliably avoid a situation where the power is shut off while the storage element is mounted on the connection portion.

  Furthermore, in the television according to the present invention, after notifying that the storage element is connected in the television, the control unit removes the storage element from the connection unit and performs the power-off operation again. , And when either of the specified time has elapsed, the power supply is shut down according to the predetermined procedure.

  In this television, after notifying that the storage element is connected, the storage element is removed from the connection section, the power is turned off again, and the prescribed time has elapsed. Turn off the power. Therefore, according to this television, the power can be immediately shut off (or the timer off operation is started) by removing the memory element, and even if the memory element is not removed after the notification, the user can However, it is not possible to cut off the power supply even though the power supply is desired to be disconnected with the storage element attached to the connection portion, or the storage element is turned off even though the power switch is turned off by the user. Therefore, it is possible to avoid the inconvenience that the power is kept supplied without being cut off because the power is not removed.

  In the television according to the present invention, when the removal of the storage element is detected by the detection unit after notifying that the storage element is connected in the television, the control unit The notification to the effect is terminated.

  In this television, when the removal of the storage element is detected by the detection unit after notifying that the storage element is connected, the notification of the connection is terminated. Therefore, according to this television, compared with the configuration in which the notification that the storage element remains connected despite the removal of the storage element from the connection unit, for example, in the timer off operation, the standby time It is possible to avoid a situation in which a notification message is displayed superimposed on a TV image or the like until the time elapses, thereby hindering viewing of the TV image.

  Hereinafter, the best mode of a television according to the present invention will be described with reference to the accompanying drawings. A television 1 shown in FIG. 1 is a rear projection type television configured to be able to display television images and the like, and includes a memory card slot 11, a card attachment detection unit 12, an image data reading unit 13, an image processing unit 14, and a tuner. 15, a broadcast signal processing unit 16, a display unit 17, a speaker 18, an operation unit 19, a power supply unit 20, a timer 21, and a control unit 22. The memory card slot 11 corresponds to a connection portion in the present invention, and is configured such that a memory card 2 inserted from an insertion slot (not shown) formed on the front panel of the television 1 can be attached (connected). In this case, the memory card 2 is an example of a storage element according to the present invention, and stores, for example, image data captured (generated) by the digital camera 3. Note that the storage element in the present invention is not limited to a card-type storage element such as the memory card 2, but includes various storage elements that are formed in a stick shape or block shape and can be mounted on various electronic devices. included. The card attachment detection unit 12 detects whether or not the memory card 2 is attached to the memory card slot 11 (connection presence / absence) and outputs a detection signal S1 that notifies the detection result to the control unit 22.

  The image data reading unit 13 reads image data stored in the memory card 2 from the memory card 2 and outputs it to the image processing unit 14. The image processing unit 14 performs image processing on the image data output from the image data reading unit 13 and causes the display unit 17 to display an image (not shown) based on the image data. The tuner 15 receives a broadcast signal of a designated channel with an antenna outside the figure and outputs it to the broadcast signal processing unit 16. The broadcast signal processing unit 16 includes, as an example, an IF circuit, an audio detection circuit, a video detection circuit, an A / D conversion unit (all not shown), and the like, and a display signal based on the broadcast signal output from the tuner 15 and Audio signals are output to the display unit 17 and the speaker 18, respectively. The display unit 17 includes an optical engine, a screen panel, and the like (not shown), and various images based on display signals output from the image processing unit 14, the broadcast signal processing unit 16, and the control unit 22, messages M1, M2, and the like. (See FIGS. 2 and 4). Specifically, the display unit 17 displays various images, messages M1, M2, and the like on the screen panel by projecting projection light that is light-modulated based on the output display signal onto the screen panel from the back side. In this case, the optical engine includes, for example, a light source, a light modulation element (for example, a digital micromirror device or a liquid crystal light valve), and a projection lens (both not shown).

  The speaker 18 includes an amplifier, a speaker, and the like (both not shown), and outputs audio based on the audio signal output from the broadcast signal processing unit 16. The operation unit 19 includes various operation switches (operation keys) such as a power switch, a channel switch, a menu switch, a cursor key, and an execution switch, and outputs an operation signal S2 corresponding to these operations to the control unit 22. In addition, the television 1 includes a remote controller having an operation switch similar to each operation switch of the operation unit 19 (not shown), and the remote operation of the television 1 is performed by operating the remote controller in the same manner as the switch operation on the operation unit 19. Is configured to be possible. The power supply unit 20 supplies power to each unit of the television 1 under the control of the control unit 22. The timer 21 starts measuring time (counting a specified time) according to the control of the control unit 22 and outputs a timer signal S3 to the control unit 22 when the specified time has elapsed. The control unit 22 controls the television 1 as a whole. Moreover, the control part 22 starts the power-off process 30 shown in FIG. 3, when the power switch of the operation part 19 is operated in the state which the television 1 is operate | moving. Furthermore, the control unit 22 performs a timer-off operation (for example, “30 minutes, 60 minutes, 90, 120 minutes”) when a time selected from four types of candidates has elapsed by a predetermined operation described later. 5 is started, the timer-off process 40 shown in FIG. 5 is started.

  Next, the overall operation of the television 1 will be described with reference to the drawings. In the television 1, when the power switch of the operation unit 19 is operated, the power supply unit 20 supplies power to the optical engine of the display unit 17 according to the control of the control unit 22. At this time, the tuner 15 receives the broadcast signal of the channel that was selected at the time of the previous power-off under the control of the control unit 22 and outputs it to the broadcast signal processing unit 16. In response to this, the broadcast signal processing unit 16 outputs a display signal and an audio signal based on the broadcast signal to the display unit 17 and the speaker 18, respectively. As a result, the television image is displayed on the screen panel of the display unit 17, and sound corresponding to the television image is output from the speaker 18. When displaying an image captured by the digital camera 3 on the television 1, first, the memory card 2 storing the image data is removed from the digital camera 3, and the memory card is inserted into the insertion port of the front panel of the television 1. The memory card 2 is inserted into the slot 11. Next, a display screen (not shown) for displaying an image based on the image data in the memory card 2 is displayed on the display unit 17 by operating the display changeover switch of the operation unit 19. At this time, the image data reading unit 13 reads the image data from the memory card 2 inserted in the memory card slot 11 and outputs the image data to the image processing unit 14. The image processing unit 14 performs image processing on the output image data. To generate a display signal and output it to the display unit 17. As a result, an image (camera image) based on the image data stored in the memory card 2 is displayed on the display unit 17.

  On the other hand, in the television 1, during the display of the television image or the camera image, the control unit 22 performs either a power switch operation or a timer-off operation setting operation based on the operation signal S 2 from the operation unit 19. Monitor whether or not At this time, when the power switch is operated, the control unit 22 starts the power-off process 30 shown in FIG. In the power-off process 30, the control unit 22 first determines whether or not the memory card 2 is installed in the memory card slot 11 based on the detection signal S1 from the card installation detection unit 12 (step 31). At this time, when the memory card 2 is not inserted in the memory card slot 11, the control unit 22 controls the power supply unit 20 to immediately cut off the supply of power to each unit of the television 1 (power off: step 32). ), The power-off process 30 is terminated. On the other hand, when it is determined in step 31 that the memory card 2 is installed in the memory card slot 11, the control unit 22, as shown in FIG. 2, reads “A memory card is installed. The message M1 (an example of “notification that the storage element is connected” in the present invention) is displayed on the display unit 17 (step 33). ). Thus, the user recognizes that the power is going to be cut off while the memory card 2 is mounted in the memory card slot 11. Further, simultaneously with the display of the message M1, the control unit 22 controls the timer 21 to start counting a predetermined time (a waiting time until the power is turned off: as an example, 30 seconds).

  Next, the control unit 22 determines that the specified time has not elapsed (step 34), and whether or not the operation signal S2 corresponding to the operation of the power switch is output from the operation unit 19 after displaying the message M1 (user Whether or not the power switch has been operated again is determined (step 35). In this case, when the memory card 2 is inserted in the memory card slot 11 and the user acknowledges that fact and shuts off the power of the television 1, the message M1 is displayed after the message M1 is displayed. Operate the power switch again according to the contents. At this time, an operation signal S2 corresponding to the operation of the power switch is output from the operation unit 19, and the control unit 22 determines that there is an operation of the power switch during the determination process in step 35, and displays the message M1 on the display unit 17 (Step 37), the power supply unit 20 is controlled to cut off the supply of power to each unit of the television 1 (step 32), and the power-off process 30 is completed. On the other hand, when it is determined in step 35 that the power switch is not operated, the control unit 22 determines whether or not the memory card 2 is installed in the memory card slot 11 based on the detection signal S1 from the card installation detection unit 12. Is discriminated (step 36). At this time, when the user who has seen the message M1 displayed on the display unit 17 removes the memory card 2 from the memory card slot 11, the control unit 22 removes the memory card 2 from the memory card slot 11 during the discrimination process in step 36. And the display of the message M1 on the display unit 17 is terminated (step 37), and the power supply unit 20 is controlled to cut off the supply of power to each unit of the television 1 (step 32). The off process 30 is terminated. As a result, the display of the message M1 on the display unit 17 is also terminated.

  Further, when it is determined in step 36 that the memory card 2 is still mounted in the memory card slot 11, the control unit 22 returns to step 34 and determines whether or not the specified time has elapsed. At this time, when the timer signal S3 indicating that the specified time has elapsed is output from the timer 21, when it is determined that the specified time (in this example, 30 seconds) has elapsed since the start of the display of the message M1, The unit 22 terminates the display of the message M1 on the display unit 17 even if the power switch is not operated again and the memory card 2 is still inserted in the memory card slot 11 (step 37). Then, the power supply unit 20 is controlled to cut off the supply of power to each unit of the television 1 (step 32), and the power-off process 30 is terminated. Further, when it is determined in step 34 that the specified time has not elapsed, the control unit 22 executes the processing from step 35 onward again. Thus, in this television 1, when the memory card 2 is inserted in the memory card slot 11 when the power switch is turned off, a predetermined time (standby time: 30 seconds in this example) specified in advance. The supply of power by the power supply unit 20 is cut off at the earlier point of time, when the power switch is operated again, or when the memory card 2 is removed from the memory card slot 11.

  On the other hand, when each operation switch of the operation unit 19 is operated and a timer-off operation (power-off operation by the sleep timer) is set, the control unit 22 starts a timer-off process 40 shown in FIG. In this case, in the television 1, when setting the power shutdown to “after 30 minutes”, for example, the menu switch of the operation unit 19 is operated to display a menu screen (not shown) on the display unit 17. , The cursor key is operated to select a desired waiting time from among the waiting time candidates (candidates for waiting time until power-off: four types of candidates of “30 minutes, 60 minutes, 90, 120 minutes” as an example) In the example, “30 minutes”) is selected and the execution switch is operated. In this example, the operation of the execution switch corresponds to the “operation of the timer-off setting switch” in the present invention, and the control unit 22 operates by operating the execution switch of the series of timer-off setting operations. The timer-off process 40 is started. The “operation of the timer-off setting switch” in the present invention is not limited to the above example. For example, when there is a “timer-off setting switch dedicated to timer-off setting” such as a sleep switch, The operation corresponds to “operation of the timer-off setting switch”.

  In the timer-off process 40, the control unit 22 first determines whether or not the memory card 2 is installed in the memory card slot 11 based on the detection signal S1 from the card installation detection unit 12 (step 41). At this time, when the memory card 2 is not inserted into the memory card slot 11, the control unit 22 controls the timer 21 to wait for the standby time set by the timer-off setting operation (30 minutes in this example). Is started (step 42). On the other hand, when it is determined in step 41 that the memory card 2 is installed in the memory card slot 11, the control unit 22, as shown in FIG. 4, “A memory card is installed. When the card is removed or the execution switch is pressed again, the sleep timer is activated ”message M2 (another example of“ notification that the storage element is connected ”in the present invention) is displayed on the display unit 17. It is displayed (step 43). Thereby, the user recognizes that the timer-off operation is to be set while the memory card 2 is mounted in the memory card slot 11.

  Next, the control unit 22 determines whether or not the operation signal S2 corresponding to the operation of the execution switch is output from the operation unit 19 after the message M2 is displayed (whether or not the execution switch is operated again by the user) ( Step 44). In this case, when the memory card 2 is mounted in the memory card slot 11 and the user acknowledges that fact and sets the timer-off operation, the message M2 is displayed and the message M2 is displayed. Operate the execution switch again. At this time, an operation signal S2 corresponding to the operation of the execution switch is output from the operation unit 19, and the control unit 22 determines that the execution switch is operated during the determination processing in step 44, and proceeds to step 46 to proceed to the display unit. The display of the message M2 for 17 is ended, and the timer 21 is controlled to start counting the standby time set by the timer-off setting operation (step 42). On the other hand, when it is determined in step 44 that the execution switch is not operated, the control unit 22 determines whether or not the memory card 2 is installed in the memory card slot 11 based on the detection signal S1 from the card installation detection unit 12. Is discriminated (step 45). At this time, when the user who has seen the message M2 displayed on the display unit 17 removes the memory card 2 from the memory card slot 11, the control unit 22 removes the memory card 2 from the memory card slot 11 during the discrimination process in step 45. Is displayed, the display of the message M2 on the display unit 17 is terminated (step 46), and the timer 21 is controlled to start counting the set waiting time (step 42).

  If the controller 22 determines in step 45 that the memory card 2 is still mounted in the memory card slot 11, the controller 22 returns to step 44 and determines whether or not the execution switch has been operated. At this time, when it is determined that the execution switch is not operated, the control unit 22 proceeds to step 45 and determines whether or not the memory card 2 has been removed. Thus, in the television 1, when the timer-off operation is set (when the execution switch is operated in the timer-off setting operation), the operation is executed when the memory card 2 is inserted into the memory card slot 11. The timer 21 starts counting the standby time when the switch is operated again and when the memory card 2 is removed from the memory card slot 11, whichever comes first. Even when neither the removal of the memory card 2 nor the operation of the execution switch is executed, the waiting time is counted by the timer 21 when a predetermined waiting time (for example, about 30 seconds) elapses. It is also possible to adopt a configuration for starting the process.

  On the other hand, in this timer-off process 40, when it is determined in step 41 that the memory card 2 is not attached, when it is determined in step 44 that the execution switch is operated again, and in step 45, the memory card 2 is removed. At any time when the determination is made, counting of the waiting time by the timer 21 is started as described above (step 42). Further, the control unit 22 determines whether or not the standby time (30 minutes in this example) has elapsed based on whether or not the timer signal S3 indicating that the set time has elapsed is output from the timer 21. (Step 47) When it is determined that the standby time has elapsed (when the timer signal S3 is output from the timer 21), the power supply unit 20 is controlled regardless of whether or not the memory card 2 is attached, and the television 1 The supply of power to each unit is interrupted (step 48), and the timer-off process 40 is terminated. Further, the control unit 22 monitors whether or not the memory card 2 is newly installed in the memory card slot 11 in parallel with monitoring whether or not the standby time has elapsed (step 49). Specifically, when it is determined in step 41 that the memory card 2 is not installed, and after the message M2 is displayed, the memory card 2 is removed and it is determined in step 45 that the memory card 2 is not installed. When the memory card 2 is inserted into the memory card slot 11 after the count start in step 42, the control unit 22 newly adds the memory card 2 to the memory card slot 11 in step 49. It is determined that the timer has been attached, and the timer-off operation is canceled (counting by the timer 21 is stopped: step 50), and the timer-off process 40 is terminated. At this time, for example, the control unit 22 causes the display unit 17 to display a message (not shown) “Timer off has been canceled”.

  Thus, according to the television 1, when the connection of the memory card 2 is detected by the card attachment detection unit 12 during the power-off operation (when the power switch is operated and when the timer-off operation is set), The control unit 22 displays messages M1 and M2 informing that the memory card is connected on the display unit 17 and shuts off the power supply according to a predetermined procedure, so that the memory card 2 is mounted in the memory card slot 11 Even if a user who has forgotten to try to shut off the power (or set the timer off operation), the message M1, M2 displayed on the display unit 17 indicates that the memory card 2 is still attached. It can be recognized with certainty. As a result, the user can remove the memory card 2 from the memory card slot 11 and attach it to the digital camera 3, thereby avoiding the situation where the memory card 2 cannot carry out photography by carrying the digital camera 3 not attached. It becomes possible to do. Moreover, according to this television 1, the structure which discriminate | determines that the control part 22 determined that the power-off operation was performed when either a power switch and a timer-off operation setting switch (this example execution switch) was operated. By adopting it, it is possible to reliably avoid a situation where the power is shut off while the memory card 2 is mounted in the memory card slot 11.

  Further, according to the television 1, after the messages M1 and M2 indicating that the memory card is connected are displayed on the display unit 17, the memory card 2 is removed from the memory card slot 11, and the power is turned off again. In addition, the power supply is cut off according to a predetermined procedure when either of the predetermined time passes is satisfied, so that the power supply is immediately cut off by removing the memory card 2 (or the timer off operation is started). In addition, even if the memory card 2 is not removed after the messages M1 and M2 are displayed, the user desires to turn off the power while the memory card 2 is mounted in the memory card slot 11. However, the power switch cannot be turned off despite the fact that the power switch cannot be turned off. It is possible to avoid the inconvenience of being continuously supplied without being interrupted power supply to have been also a memory card 2 regardless not removed. Further, according to the television 1, when the removal of the memory card 2 is detected by the card attachment detection unit 12 after displaying the messages M1 and M2 indicating that the memory card is connected on the display unit 17, the message is displayed. Since the display of M2 is terminated (or the power is turned off), the display (notification) of the messages M1, M2, etc. is continued even though the memory card 2 is removed from the memory card slot 11. For example, when the timer is off, for example, it is possible to avoid a situation in which messages M1, M2 and the like are superimposed on the television image displayed on the display unit 17 until the standby time elapses, thereby hindering viewing.

  In addition, this invention is not limited to said structure. For example, the rear projection type television has been described above, but the television in the present invention is not limited to this, and the present invention is applied to a television having various displays such as a liquid crystal display, a plasma display, and an organic EL display. be able to. In this case, the television in the present invention is not limited to a television in which the display and the tuner are integrally configured, and includes various televisions in which the display and the tuner are separately configured. Further, the present invention can also be applied to various recording devices including a memory card slot 11 such as a DVD recorder or an HDD recorder. Further, the television 1 is configured to notify that the memory card 2 is attached by displaying character strings such as messages M1, M2 on the display unit 17, but the present invention is not limited thereto. Without being limited thereto, it can be configured to notify that the memory card 2 is mounted by various notification methods such as notification by voice, notification by warning sound, and notification by lighting (flashing) of an indicator.
