Description

  The present invention relates to a display control technique for an operation panel / display panel provided in a recording / reproducing apparatus.

  In order to meet the demands of the multimedia era, recent recording / playback devices include a DVD device using a DVD (Digital Versatile Disk) as a storage medium for large-capacity data and a large-capacity and inexpensive hard disk drive (HDD). It is common to have.

  The DVD apparatus uses a red semiconductor laser having a wavelength of 650 nm as a pickup for the optical disk. A general DVD has a recording capacity of 4.7 GB.

  On the other hand, as a next-generation optical disk capable of storing a larger amount of data than DVD, recently, a Blu-ray Disc (registered trademark, hereinafter referred to as “BD”) using a blue light source with a wavelength of 400 nm band is used. ), And HD D-Buidy (High Definition DVD, hereinafter also referred to as “HD DVD”). For example, in the case of BD, three types of recording capacity of a single-sided single layer of 23.3 GB, 25 GB, and 27 GB are standardized. In the case of HD DVD, a single-sided single-layer recording capacity of 15 GB has been announced, and a specification of 20 GB is also being studied. Both of them have a recording capacity of 15 GB (Giga byte) or more. For example, BD can record the entire high-definition broadcast of 2 hours or more on a single disc, so it can support future hibition broadcasts. Excellent performance (see, for example, Patent Document 1).

  In addition to the existing compact disc (CD) and DVD, in order to support BD, a laser light source with three wavelengths of short wavelength (BD) in addition to long wavelength (for CD) and medium wavelength (for DVD). Has been proposed (see, for example, Patent Document 2). In this apparatus, pickups corresponding to the above three types of wavelengths are provided to save space by using a single drive.

  However, although the optical disk device described in Patent Document 2 can save space, since there is only one disk insertion / removal port and only one disk can be driven, processing such as dubbing becomes complicated. The usability is not always good. In addition, there are recording / reproducing apparatuses including two or more disk devices, but the operation state of the recording / reproducing apparatus is displayed mainly on the basis of character information in one display area, and thus is not easily understood by the user. In particular, since the display panel, the detachable opening of the detachable recording medium, the operation buttons, and the like are gathered on the front, it is difficult to take a sufficient area with respect to the display panel. Further, due to the provision of many drives (including the case where there is only one insertion slot), the power consumption of the display unit and the display control unit for notifying the operation state of each drive tends to increase.

  An object of the present invention is to make display easy to understand while considering power consumption in a recording / reproducing apparatus including an optical disk device including a Blu-ray Disc (BD).

  The recording / reproducing apparatus of the present invention is a recording / reproducing apparatus provided with a disc device including a Blu-ray disc (BD), wherein a first panel that can be opened and closed is provided on the casing, and the operation status of the disc device is displayed on the panel. The recording / reproducing apparatus includes a display unit and a second display unit that is provided on one surface of the casing that is exposed when the panel is opened and displays an operation status of the disk device. According to this apparatus, since the display unit and the operation unit can be appropriately provided on the two surfaces based on the opening and closing of the front panel, the degree of freedom in layout of the display unit and the operation unit is increased. Furthermore, a detection unit that detects opening and closing of the panel is provided, and when the detection unit detects a closed state of the panel, a display control unit that performs control to reduce or stop power supply to the second display unit It is characterized by having. Or when the said detection part detects the open state of the said panel, it has a display control part which performs control which reduces or stops the electric power supply to a said 1st display part, It is characterized by the above-mentioned. This reduces power consumption and closes the panel by reducing or stopping the power supply related to the display necessary for visual recognition when operating the disk device according to the opening and closing of the front panel and the display not related to visual recognition. It is possible to prevent heat accumulation inside the back side of the panel.

  According to one aspect of the present invention, a housing, at least one electronic device provided in the housing, and a position that can be opened and closed on one surface of the housing and closes an operation unit of the electronic device are provided. A panel, a first display unit provided on the panel for displaying an operation status of the electronic device, and an operation status of the disk device provided on the casing surface exposed when the panel is opened based on power supply. A second display unit for displaying, a detection unit for detecting opening / closing of the panel, and a power supply to the second display unit when the detection unit detects a closed state of the panel. Alternatively, an electronic apparatus having a display control unit that performs control to stop is provided.

  According to another aspect of the present invention, a housing, at least one electronic device provided in the housing, and a position that can be opened and closed on one surface of the housing and closes an operation unit of the electronic device are provided. A display method for an electronic device, comprising: a display panel, and a display unit having a light source that emits light by power supply on one surface thereof, the step of detecting opening and closing of the panel; and the detection of closing of the panel And a step of controlling the power supply to reduce the power supply to the light source.

Note that a program for causing a computer to execute the above steps also falls within the scope of the present invention.

  The present invention provides a recording / reproducing apparatus having a panel that can be opened and closed on one surface of a housing, and reduces power consumption associated with light emission of a light source of a display unit that is exposed when the panel is opened and emits light from a light source when the panel is closed. It is possible to avoid the accumulation of heat inside the panel when the panel is closed. In particular, when used as an optical drive corresponding to a recording medium with a high recording density such as a Blu-ray disc, the processing density of the disc is high and fine, so the influence of heat accumulation increases. The advantage to use is great.

  In this specification, the optical disk is, for example, a reproduction-only CD-ROM, DVD-ROM, CD-R (W), DVD-R (RW), and the like that can be reproduced and recorded, and a Blu-ray disc (BD), Includes HD DVD. The optical disk device refers to a drive device that can drive these media. In the following embodiments, the first display unit described in the claims of the present application includes first to third display units, and the second display unit includes fourth to sixth display units. .

FIG. 1 is a perspective view showing an external configuration example of the recording / reproducing apparatus according to the present embodiment, and shows a state in which a front panel is closed. FIG. 2 is a view corresponding to the perspective view of FIG. 1 and showing a state in which the front panel is opened. 3A to 3C are a front view corresponding to FIG. 1, a front view corresponding to FIG. 2, and a top view (partially representing) corresponding to FIG. 2. FIG. 4 is a view showing an arrangement example of the optical disk device arranged in the recording / reproducing apparatus according to the present embodiment. FIG. 5 is a functional block diagram showing an internal configuration example of the recording / reproducing apparatus according to the present embodiment. FIG. 6 is a diagram showing a configuration example of a program that performs control processing and the like of the recording / reproducing apparatus according to the present embodiment. FIG. 7 is a diagram showing a configuration example of a remote control device (hereinafter referred to as “remote control device”) capable of remotely operating the recording / reproducing device. 8 and 9 are flowcharts showing the flow of display control processing. FIG. 10 is a diagram illustrating a display example on the display unit of the front panel. FIGS. 11A and 11B are diagrams illustrating display examples of the display unit in a state where the power of the recording / reproducing apparatus A is actually turned on.

  As shown in FIGS. 1 to 4, the recording / reproducing apparatus A according to the present embodiment is different from the DVD apparatus 31 that is the first optical disk apparatus in that the recording apparatus and the like have different standards such as recording capacity. This is a so-called two-tray recording / reproducing device that is placed adjacent to the BD device 35, which is an optical disk device. Even when it has an appearance that emphasizes slimness. As will be described later with reference to FIG. 4, this external appearance is such that the vertical thickness of the casing is as thin as possible by arranging the two optical drive devices 31 and 35 on the left and right when placed horizontally. I have to. Assuming that the liquid crystal television is mounted on an open rack, the thinness when it is placed horizontally in the open rack is emphasized.

  In addition, the housing 1 for housing the disk drive device is formed by injection molding of ABS polycarbonate resin, which is a flame-retardant plastic containing no halogen material, and a thin upper plate 1a is disposed on the upper surface. The upper plate 1a has a deeper finish than the other outer surface of the casing, so that mechanical strength can be ensured and a sense of luxury and slimness are produced.

  FIG. 4 is a diagram showing an arrangement example of each disk device in the recording / reproducing apparatus according to the present embodiment. As shown in FIG. 4, the recording / reproducing apparatus according to the present embodiment has a DVD apparatus 31 on the right side and a BD apparatus 35 on the left side when viewed from the front when the general horizontal arrangement is used. A hard disk (HDD) device 33 is disposed below the DVD device 31. The optical disk devices 31 and 35 having a certain thickness are arranged on the left and right sides, and the hard disk device HDD 33 that can be reduced in thickness is arranged below the DVD device 31, whereby the thickness of the housing 1 can be reduced. Further, since the processing is finer than that of a DVD disk, a high positional accuracy between the pickup and the disk is required (that is, weak against vibration). By disposing the BD device 35 and the HDD device 33 below the DVD device 31, the influence of vibration caused by the operation of the HDD device 33 can be minimized. These disk devices 31, 33, and 35 are generally recordable / reproducible, but include, for example, a case where a DVD device is dedicated for reproduction.

  As shown in FIGS. 1 and 3 (a), a recording / reproducing apparatus A according to the present embodiment includes a housing 1 on which an upper plate 1a is disposed, and an openable front panel provided in front in a horizontal position. 25a. On the left and right of the front panel 25a are an RC light receiving unit 17 for receiving a command by infrared rays from a power on / off switch 1b and a remote control device (hereinafter referred to as "remote control device") shown in FIG. A panel opening switch 25b for opening 25a and a front panel locking mechanism 25 for locking the front panel 25a are provided.

  Although a detailed description of the front panel lock mechanism 25 is omitted, the front panel 25a is normally locked, and the panel open switch of the remote control (the tray open / close switch in FIG. 7B also has this function) or the panel By turning on the opening switch 25b, the front panel 25a is pushed in the opening direction.

  Once the front panel 25a is pressed, the front panel 25a is rotated by the weight of the front panel 25a in the opening direction until the angle between the front of the casing and the front panel 25a is about 90 degrees, and as shown in FIG. The rotation stops when the angle between the front and the front panel 25a becomes about 90 degrees. The front panel 25a can be opened by an operation from the remote control device by releasing the lock mechanism of the front panel 25a by the remote control device.

  The front panel 25a is provided with a first display unit 40 in a state in which the display panel is closed, and the first display unit 40 includes a first display unit 3 to a third display unit described below. It consists of two display parts, and they are arranged close to each other. The first display unit 40 includes a substantially circular first display unit 41, second display units 43 and 45, and a third display that are arranged with a certain interval in the horizontal direction when the housing 1 is placed horizontally. Three display parts of the part 47 are arranged and formed.

  As shown in FIGS. 2 and 3 (b), when the front panel 25a is opened, the recording / reproducing apparatus A is placed on the back side when the front panel 25a is closed on the front side of the housing 1. Front portions 31a and 35a appear, in which the disc tray for loading the discs of the DVD device 31 which is the built-in first optical disc device and the BD device 35 which is the second optical disc device advances and retreats. Open / close switches 31b and 35b for opening and closing the optical disk devices 31 and 35 are provided for the optical disk devices 31 and 35, respectively. By pressing the open / close switches 31b and 35b, trays for loading DVD disks or BD disks (not shown) corresponding to the respective optical disk devices 31 and 35 are provided so as to be able to advance and retract.

  Below the area where the DVD device 31 and the BD device 35 are arranged side by side, for example, an IEEE 1394 terminal (DV terminal) and a slot 21 for a B-CAS card are provided. The B-CAS card is a card necessary for receiving various broadcasting services such as terrestrial digital television broadcasting, BS digital broadcasting, and 110-degree CS digital broadcasting, and is also used for copyright protection of digital broadcasting programs and the like. . For example, in order to use a broadcast service such as a digital broadcast free broadcast, pay broadcast, pay-per-view broadcast, NHK, automatic display message, and data broadcast interactive service, the slot 21 for the B-CAS card is used. It is necessary to insert a B-CAS card. Reference numeral 21a denotes a push button for taking out the B-CAS card inserted into the B-CAS card slot.

  Further, between the IEEE 1394 terminal (DV terminal) and the slot 21 for the B-CAS card, a slightly smaller inner display section 48 (fourth to sixth) having the same form as the display section 40. Display units 48a to 48c are arranged in the horizontal direction at a certain interval). This inner display section serves as a selection operation key that also serves as a display, and also serves as an operation state notifying unit that notifies each operation state of the DVD, HDD, and BD in order from the left side in the drawing. The DV terminal is also provided on the back side of the recording / reproducing apparatus A, and is generally used as an interface for taking in the video from the DV camera to the HDD drive or the like at a high speed. A terminal can be selected and used.

  Further, as shown in FIG. 2 and FIG. 3 (c), a direction key having a function similar to that of the direction key of the remote controller RC in FIG. 7 (a) and an enter button are provided on the back surface 25d side of the front panel. An operation unit 61a, a switch for starting and stopping the reproduction operation, each of which is a semicircular shape and is a circular switch, a reproduction switch 61b having a light emitting area on the outer circumference of the circle, and the reproduction switch There is provided a recording switch 61c provided adjacent to the switch 61b and having the same shape. As will be described later, the light emission color at the time of display is determined according to the operating state. The operation unit 61a using direction keys and selection keys is used for moving and determining menu items on a menu screen, for example. The light emitting area is controlled to light up when the front panel 25a is open.

  As described above, each adopts a two-tray system including a DVD device having a disk drive unit and a BD device, and also includes a built-in hard disk device. The delay caused by the startup time can be shortened as much as possible. By using the two-tray system, for example, two types of discs with different standards can be placed in a disc device having the same standard, and information can be read in parallel with information reading times of different discs. As a result, it is possible to perform the startup process of the disk device in a short time. In other words, there is an advantage that the delay caused by reading the information on the disk required when the two types of disks are loaded and unloaded can be reduced by reading the information on the two disks in parallel.

  In addition, by disposing the display / operation system on the front panel, the housing-side surface when the front panel is opened, and the back surface of the front panel, for example, a display unit provided on the front panel Can be made large, and the visibility of the display unit of the user can be further improved. In particular, as in the case of the storage / reproduction device according to the present embodiment, the user can be notified of the operation status of the disk device and the data moving direction by a triple large circular display provided on the front panel. Visibility can be improved without impairing the aesthetics compared to the case of simple character display.

  Next, an internal configuration example of the recording / reproducing apparatus A according to the present embodiment will be described with reference to the entire functional block diagram of FIG. 5 and FIGS. 6 and 7. The description will be made with reference to FIGS. As shown in FIG. 5, the recording / reproducing apparatus A according to the present embodiment includes a CPU 3 that performs overall control, and a functional block group that executes each function. As described above, the DVD device 31, the HDD device 33, and the BD device 35 are provided as blocks having a recording / reproducing function.

  Each of these disk devices 31, 33, and 35 operates based on a control command from the CPU 3 via the disk drive control unit 37 or directly. Actually, in the case of the remote control device RC, an infrared signal is received by the RC light receiving unit 17 by operating each operation button of the remote control device shown in FIG. Then, a signal corresponding to the operation is received and transmitted to the CPU 3. The CPU 3 outputs a command signal for instructing each functional block so as to perform an operation based on the above operation based on the received signal.

  For example, when the terrestrial digital broadcast selection button 70b is pressed in the broadcast selection unit 70 of the remote control device RC and the BD selection button 71c is pressed in the target device selection unit, the terrestrial digital broadcast is applied to the BD disc in the BD device 35. Program content can be recorded. Since a BD disc can store a larger amount of data than a DVD disc, for example, a digital high-definition broadcast of 2 to 3 hours or more can be recorded on a single optical disc with high image quality.

  At the time of recording, when recording terrestrial digital broadcasting, the image / audio signal processing unit 5 including a recording encoder / decoder records, for example, a video signal / audio signal from a digital high-definition broadcast program on a BD disc. For example, the signal recorded in the BD device 35 is converted into a format that can be displayed on the display monitor. At this time, the operating status of the BD device 35 is sent to the CPU 3. Thus, the CPU 3 can appropriately monitor the operation status of each disk device and give an appropriate instruction.

  Furthermore, the recording / reproducing apparatus A according to the present embodiment is associated with the CPU 3 and includes a ROM 7 for storing a program for causing the CPU 3 to execute various processes described later, and a RAM 11 for developing the program and processing it at high speed. The broadcast signal from the antenna is input, the content signal obtained when the disk device is driven, the video output from the D terminal is output to a display monitor such as a liquid crystal TV, or connected to a DV camera. An interface unit 15 that includes an IEEE 1394 terminal (DV terminal), a LAN terminal connected to the Internet, and the like, and controls input and output of various signals.

  Further, the RC light receiving unit 17 described above, the B-CAS card slot 21, the cooling fan 23 for enhancing the heat radiation effect, and the front panel driving unit 25 for opening the front panel 25a, which opens and closes the front panel. It has a front panel drive unit 25 including a detection unit (not shown) that detects a state, and an input unit 61 that receives various input operations. Further, in relation to the front panel drive unit 25, a front panel open / close detection unit 25c for detecting the open / closed state of the front panel is provided. For example, the front panel open / close detection unit 25c is an optical sensor provided on the exposed surface of the housing when the front panel is opened, and is an optical sensor that detects an increase in the amount of light generated when the front panel is opened. Alternatively, it may be a mechanical switch provided on the back side or exposed surface of the front panel, and a switch that advances and retreats according to opening and closing.

  In addition, the disk device drive control unit 37 and the display unit 40 provided on the front panel 25a are arranged at a certain interval in the horizontal direction when the housing 1 is placed horizontally as described above. The substantially circular first display unit 41, second display units 43 and 45, and third display unit 47 are provided, and display control is performed by the CPU 3 via the display control unit 51. Similarly, the selection switches that also serve as the fourth to sixth display units 48 a to 48 c described above are subjected to display control by the CPU 3 via the display control unit 51. Further, each disk device is provided with detection units 31c, 33c, and 35c for detecting the presence / absence of a disk, a driving state, and the like, and signals relating to the presence / absence of an optical medium and a driving state in each corresponding disk device are detected. The units 31c, 33c, and 35c are configured to be sent to the CPU 3 via the disk drive control unit 37. A position detection unit 27 that includes a gravity sensor or a position sensor and detects the position of the recording / reproducing apparatus (horizontal or vertical) is also provided.

  FIG. 6 shows a configuration example of a program group stored in the ROM 7. The disk drive control program P 1 that controls the drive of various disks, the display control program P 2 that controls the display of the display unit, and the interface unit 15. Interface control program P3 that controls interface switching, signal conversion, etc., panel / fan control program P4 that controls the operation of the front panel 25a / fan 23, etc., and signal processing (conversion of image signals / audio signals) And an image / audio signal processing program P5 for performing (including). Each program listed here is an example, and in actuality, each program performs a series of controls in conjunction with each other.

  Next, the function of each function will be described.

  First, details of the configuration of the display unit and the display control unit and display control based thereon will be described in detail.

  As described above, the display unit 40 provided on the front panel 25a is spaced apart in the horizontal direction when the casing 1 of the recording / reproducing apparatus A is placed horizontally as shown in FIG. The first display unit 41, the second display units 43 and 45, and the third display unit 47 are arranged in a substantially circular shape. The first display unit 41, the second display units 43 and 45, and the third display unit 47 have a shape that symbolizes a disc and a relatively large diameter that is about half the thickness of the optical disc apparatus A. An easy-to-see display is formed. As long as the display of the triple circular display (lighting on / off and lighting color) is confirmed, the current operation status and current state of the disk device of the recording / reproducing device of the relatively complicated HDD device + two-tray type optical disk device There is an advantage that the moving direction of data can be easily understood at a glance.

  If it demonstrates in detail, the 1st display part 41 will be provided in the back side, for example, two types of LED is provided so that light emission of R (red) or B (blue) is possible. On the front side, light from an LED (not shown) is blocked and a light shielding or translucent plate 41a on which a logo mark of a DVD disc is displayed as will be described later, and a light transmission portion 41b provided in a ring shape on the outer periphery thereof. And a light transmissive portion 41b formed of a transparent plastic plate, for example, which transmits light emitted from the LED to the front side. The first display unit notifies the user of the operating state of the DVD device with the logo mark and the color emitted from the light transmission unit 41b.

  Similar to the first display unit 41, the third display unit 47 is also provided with two types of LEDs on the back side so that R (red) or B (blue) light can be emitted. On the front side, there is a light shielding plate 47a that blocks a light from an LED (not shown) and displays a logo mark of a BD disc as will be described later, and a light transmitting portion 47b provided in a ring shape on the outer periphery thereof. And a light transmitting portion 47b formed of a transparent plastic plate that transmits light emitted from the LED to the front side. The first display unit notifies the user of the operating state of the BD device by the color emitted from the light transmitting unit 47b together with the logo mark.

  Between the 1st display part 41 and the 3rd display part 47, the 2nd display part 43 * 45 is formed in the position away from each display part by a certain distance. Although not shown in the figure, the second display unit is an LED as a reflector and a light source from the back side, preferably a surface light source 43 obtained by an edge light and a light guide plate, and a position facing this surface light source 43. The circular liquid crystal panels 45 provided in the are sequentially provided from the back surface to the front surface side. The second light emitting unit 40 is an image of a disk of a hard disk device, and is configured such that characters appear on the liquid crystal panel 45 when the surface light source is turned on.

  These first to third display parts can be made to image a disk by making it the same shape as that of the disk, and the user can image a DVD disk and a BD disk together with the logos described. Let Further, the first to third display units 41, 43, 45, and 47 are arranged close to each other and each form a divided display unit. The first display unit can display the operation status of each disk device and the status related to data exchange between the disks. Compared to the case of displaying the operation status of each disk and data exchange on one display unit using text data etc., it is much easier to understand visually and the situation can be grasped quickly. There is an advantage that can be. Of the first to third display sections, a small lighting section is provided on the first display section 41 side so that it can be known that a recording command has been issued.

  In a state where the front panel is opened, any one of the disk devices 31, 33 and 35 selected by the selection switches also serving as the fourth to sixth display units 48a to 48c is switched to the reproduction switch 61b or the recording switch. A playback state or a recording state can be set by 61c. At this time, the opening region emits light in a color corresponding to the operation. Thereby, even when the front panel is opened, the operating state of the disk device can be known. For example, a blue light indicating that the corresponding reproduction process is being performed is emitted from a ring-shaped opening formed on the outer periphery of the reproduction switch 61b, and a recording process is performed from the ring-shaped opening area on the outer periphery of the recording switch 61c. An orange or red light indicating that the operation is being performed is emitted.

  In the recording / reproducing apparatus according to this embodiment, the front panel display unit 40 and the display unit 48 that is visible when the front panel is opened emit light by different light sources, and the front panel open / closed state detected by the front panel open / close detection unit 25c is detected. Accordingly, the CPU 3 emits light via the display control unit 51 so as to adjust the amount of light emitted from the display unit 40 of the front panel and the display unit 48 that is visible when the front panel is opened or to switch on / off. Has control over. That is, when the front panel opening / closing detection unit 25c detects the opening of the front panel, the light source of the display unit 40 of the front panel is switched from on to off, and the front panel opening / closing detection unit 25c detects the closing of the front panel. In this case, control is performed to switch the light source of the display unit 48 that is visible with the front panel open from on to off. In this way, by turning on only the light source of the display panel to be used and turning off the other light source, the power supplied to the light source not seen by the user is reduced, and the power consumption of the apparatus is reduced. Can be achieved. In addition, when the front panel 25a is closed, the power supply to the light source of the internal display unit 48 is stopped and the light emission is turned off, so that the amount of heat generated in the front panel 25a when the front panel 25a is closed can be reduced. It can solve problems such as cloudiness.

  Hereinafter, display control of the display unit of the front panel provided on the front panel 25a will be described in detail with reference mainly to FIGS. 1, 5, and 8 to 11. FIG. The reference numerals will be described with reference to all drawings. First, a basic display control method will be described. In the first to third display units 41, 43, 45, and 47 of the display unit 40, as a basic display method, color-coded display is performed by three colors of white, blue, and red. The white color indicates that the disk device is currently operable and is a disk device excluding the disk device that is being played back or recorded. That is, when the DVD device 31 or the BD device 35 is in a standby state (including a case where a recording medium is inserted), white display is performed. White is reminiscent of the image that nothing is working, and is suitable for notifying the user that playback or recording is not in progress. The blue display indicates that the content recorded on the disc is being played back, and the red display indicates that the content is being recorded (recorded) on the disc, thereby clarifying the operating status of the disc. Can be recognized.

  On the other hand, the basic lighting policy in the display unit is based on the following priority order. 1) When the HDD is operating (recording or reproducing), the liquid crystal panel 45 displays the operation status of the HDD. The second display units 43 and 45 basically display the status of the HDD that plays the central role of the recording / reproducing device, so that it is possible to display characters on the liquid crystal panel 45 in addition to color display. Compared with the display units 41 and 47, it has a multi-function. 2) When the HDD is not operating, information such as the operating status (playback / recording) of the operating DVD device or BD device is displayed on the liquid crystal panel 45 as characters. 3) When reproduction and recording are performed simultaneously, reproduction information is preferentially displayed on the liquid crystal panel 45.

  Next, display control of the display unit of the recording / reproducing apparatus according to the present embodiment will be described with reference to the flowcharts of FIGS. 8 and 9 and other drawings. First, in step S1, the power switch of the remote control device RC is turned on. The CPU 3 receives a power-on command from the remote controller RC via the RC light receiving unit 17 and actually turns on the power of the recording / reproducing apparatus A. Display examples of the display portion in this state are shown in FIGS. As shown in FIGS. 11A and 11B, in the first display unit 41 for DVD, the white LED of the white LED blinks from the light transmitting unit 41b. In the third display section 47 for the BD disc, the white blinking display is similarly performed. At this time, in the second display units 43 and 45 for the HDD device, since the HDD is a recording / reproducing medium in which a disk is always present and always accessible at random, a white light is lit when the power is turned on. The display for notifying the activation of the recording / reproducing apparatus as the LCD display, for example, the character “HELLO” is scroll-displayed only once, for example. As shown in FIG. 10, the LCD display can display up to three characters in order to enlarge the characters, and scroll display can be performed at a relatively low speed (for example, about 2 Hz). Yes. The user can easily recognize, for example, a character string “HELLO” because large characters are scroll-displayed at a low speed.

  Next, in step S2, the CPU 3 acquires the current state of each disk device (DVD device 31, HDD device 33, BD device 35) from the respective detection units 31c, 33c, 35c via the disk drive control unit 37. At the same time, for example, the presence or absence of a broadcast signal is detected. If there is no disk in the disk device, it is turned off when it is detected that there is no disk, but when the CPU 3 recognizes that there is a disk corresponding to the disk device (read / write) (DVD) , The reading of the BD disc is completed), and the display is switched from blinking white point to extinguishing display by a command from the CPU 3 via the display control unit 51. At this time, in the second display units 43 and 45 for the HDD device, when a TV program broadcast from the interface unit 15 is received, the information of BS103CH which is the channel of the program blinks by the white LED backlight. LCD display in the state. Based on this display, the user can know the program currently in the reception standby state.

  Next, when the disk reading processing step and the program reception channel selection processing step are completed, display based on the information detected in step S2 is performed in step S3. That is, as shown in FIG. 11, when the disc information reading process in the DVD device 31 and the BD device 35 is completed, the white light changes to the light-off state. When the preparation in the HDD device 33 is completed, the information of the BS 103CH is confirmed and displayed on the LCD in a lighting state by the white LED backlight. The user can know that all the disk devices are in the standby state in this state.

  Next, in step S4, a process of detecting whether or not an operation for a new operation or data movement for each disk device has been performed is performed constantly or periodically until the CPU 3 detects a new operation. When a new process is detected, the process proceeds to step S5, and a new display is performed on the display unit 40 based on information relating to detection of operation input of any of the DVD disk, HDD, and BD disk and data movement.

  In step S6, it is detected whether or not there is a new change in the state in step S5. If there is a new change (Yes), the process proceeds to step S7, and the state of each changed device is detected. Based on the detected information, the display status and priority order are taken into consideration, and the operation status, data movement status, etc. are displayed on the LED and LCD, and the process is terminated (step S8).

  FIG. 9 is a flowchart showing the flow of processing when the opening of the front panel 25a is detected. When the CPU 3 detects the opening operation of the front panel 25a from the step S5 of FIG. 8 via the front panel open / close detection unit 25c (step S11), the operation state of each disk is indicated on the LEDs in the front panel 25a in step S12. Is displayed. At this time, the LEDs on the display unit of the front panel 25a are turned off. Next, in step S13, processing such as disk replacement is performed, and at this time, an eject request signal for the disk tray is detected. After loading the disk onto the disk tray, if it is detected in step S14 that the panel is closed, the CPU detects that the panel is closed, and the process proceeds to step S2 in FIG. At this time, after detecting the closing of the front panel 25a, the LED of the display unit 40 provided on the front panel 25a is turned on, and the LED of the display unit 48 exposed when the front panel is opened is turned off, and then from step S2. Start processing. The on / off switching between the display unit 40 and the display unit 48 may be controlled so as to be turned off after a slight delay after being turned on. By doing so, for example, when the front panel 25a is opened immediately after closing, there is an advantage that the on / off process is not actually performed and the process is simplified.

FIG. 11 is a diagram showing a display example of the second display units 43 and 45 shown in FIG. The second display sections 43 and 45 in the display 40 shown in FIG. 10 can display an LCD of up to three characters in order to enlarge the characters for easy viewing. The LCD display is scrolled at a relatively low speed (for example, about 2 Hz). The user can easily recognize, for example, a character string “HELLO” because large characters are scroll-displayed at a low speed. FIG. 11 is a diagram illustrating a display example of liquid crystal characters on the LCD display unit of the second display unit. As shown in FIG. 11A, (1) at the time of tuner reception, the broadcast type (BS broadcast in this case) and channel (103CH in this case) received by the tuner are displayed. When the external AV is input in (2), for example, L1 is displayed. When DV (IEEE1394) is input in (3), DV characters are displayed. At (4) iLINK (TS), a message to that effect is displayed. At this time, IEEE 1394 has two signals, ie, a DV signal and an iLINK (TS) signal having different data formats, which are input and output from a common terminal.

  As shown in FIG. 11B, during dubbing (copying) of (1), 1 to 3 characters of COPY characters are scroll-displayed. At the time of dubbing (move) in (2), one to three of the MOVE characters are scroll-displayed. During the reproduction of (3), 1 to 3 characters of the PLAY characters are scroll-displayed. In addition, DL at the time of satellite download in (4), CAS at the time of B-CAS communication in (5), EPG at the time of acquisition of terrestrial digital EPG in (6), EPG at the time of program guide display in (7) Are displayed when the backlight is turned on.

  The above display example is an example, and the operation status of each disk device and the data moving direction are recorded by the color lighting of the first to third display units and the character display of the LCD of the second display unit. The status of the playback device can be displayed.

As shown in FIG. 12 (A), when the power is turned on, the first display unit 41 blinks white, the second display units 43 and 45 are lit white and LCD display (in this case, HEL scrolls once). Then, the third display unit 47 blinks white. Thereby, it can recognize that it is at the time of starting. Next, during tuner reception / disc reading, the first display unit 41 blinks in white, and the second display units 43 and 45 light up white and display on the LCD (in this case, the BS 103CH display blinks at 2 Hz). In the third display unit 47, white blinking is performed. As a result, it can be recognized that the tuner has received the 103CH of the BS. Next, the first display unit 41 is turned off, the second display units 43 and 45 are lit white and LCD is displayed (in this case, the 103CH display of BS blinks at 2 Hz), and the third display unit 47 is also turned off. Thereby, it can be recognized that the initial reading process of the DVD and the BD is completed and the preparation of the HDD recording or the like is completed. In the state where the above-mentioned front panel is opened, the first display unit, the second display unit, and the third display unit are all turned off. As shown in FIG. 12 (B), in the disk reading (tray closed) display, the white blinking is changed to the off state in accordance with the reading and completion of the DVD, and the BD is similarly changed.
