Since the control is performed, it is possible to prevent a malfunction related to a key operation due to a cause such as a foreign object being caught when the panel is opened and closed. In particular, the usability of a recording / reproducing apparatus including a plurality of optical disk apparatuses including a BD apparatus can be improved.

  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.

  A recording / reproducing apparatus according to a first embodiment of the present invention will be described with reference to the drawings. 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 diagram showing an arrangement example of the optical disk device arranged in the recording / reproducing apparatus according to the present embodiment.) FIG. 5 shows an example of the internal configuration of the recording / reproducing apparatus according to the present embodiment. It is a functional block diagram shown. 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”) that can remotely operate the recording / reproducing device.

  As shown in FIGS. 1 to 3, 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 second standard is different from the DVD apparatus in terms of storage capacity and the like. 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 outer surface of the other casing, thereby producing a sense of luxury and slimness while maintaining the vaporizer strength.

  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. The 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 HDD device 33 that can be thinned 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 HDD device 33 can be minimized. These disk devices 31, 33, and 35 are all 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 that receives an infrared command from a power on / off switch 1b and a remote control device (hereinafter referred to as "remote control") shown in FIG. 7, and a front panel 25a. A panel opening switch 25b for opening the front panel, and a front panel locking mechanism 25 for locking the front panel 25a.

  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.

  A display unit 40 is provided on the front panel 25a. The display unit 40 includes a substantially circular first display unit 41, second display units 43 and 45, and a third display unit arranged with a certain interval in the horizontal direction when the housing 1 is placed horizontally. 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. The front portions 31a and 35a of the trays of the DVD device 31 that is the first optical disc device and the BD device 35 that is the second optical disc device appear. Open / close switches 31c, 35c for opening / closing the respective optical disk devices 31, 35 are provided for the respective optical disk devices 31, 35. By pushing the open / close switches 31c and 35c, trays for loading DVD disks or BD disks (not shown) corresponding to the respective optical disk devices 31 and 35 are advanced and retracted.

  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 broadcasting services such as digital broadcasting free broadcasting, pay broadcasting, pay-per-view broadcasting, NHK, automatic display message, and data broadcasting interactive services, slots for B-CAS cards must be used. It is necessary to insert a B-CAS card into 21. 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. It is assumed that the push button for taking out the B-CAS card and the inner display unit include switches such as a selection operation key for both display and the operation unit described later.

  Furthermore, 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 25b 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.

  In the present embodiment, the B-CAS card button 21a, the operation button of the inner display unit 48, the operation unit 61a composed of the direction key and the enter button, the playback switch 61b, and the recording switch 61c are controlled objects. Included in operation buttons.

  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 due to the associated start-up time can be minimized. By using the two-tray method, for example, by inserting two types of discs with different standards into a disc device that matches the standards, the information reading time of different discs can be read in parallel, and the disc can be read in a short time. A device activation process can be performed. That is, there is an advantage that the delay caused by reading the information on the disc when the two discs are loaded / unloaded can be reduced by performing the information reading on the two discs 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, the display section provided on the front panel is enlarged. The visibility 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 disc selection button 71c is pressed in the target device selection unit, the terrestrial wave is applied to the BD disc in the BD disc drive device 35. Digital broadcast program content can be recorded. Since a BD disc can store a larger amount of data than a DVD disc, for example, CS broadcasts of two to three hours or more can be recorded 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 can record a video signal / audio signal from, for example, a CS 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. An IEEE 1394 terminal (DV) for inputting a broadcast signal from an antenna, outputting a content signal or D video obtained when the disk device is driven, to a display monitor such as a liquid crystal TV, or connecting to a DV camera And an interface unit 15 for controlling input / 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 first display unit 41, the second display units 43 and 45, and the third display unit 47, which symbolize the shape of each disk, are provided by the CPU 3 via the display control unit 51. Display control is performed. 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 related 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. Note that FIG. 5 includes positions for detecting the position of the recording / reproducing apparatus (horizontal or vertical), including a gravity sensor and a position sensor, as will be described in a fourth modification of the present embodiment described later. The detection unit 27 is described.

  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. As shown in FIG. 3 (a), the display unit 40 provided on the front panel 25a is an abbreviation arranged with a certain interval in the horizontal direction when the casing 1 of the recording / reproducing apparatus A is placed horizontally. A circular first display unit 41, second display units 43 and 45, and a third display unit 47 are provided. The first display unit 41, the second display units 43 and 45, and the third display unit 47 are relatively large and easy-to-see display units having a diameter of about half the thickness of the optical disc apparatus A, As long as the display of the triple circular display (lighting on / off and lighting color) is confirmed, the current operation status of the disk device of the relatively complex HDD drive + 2-tray recording / reproducing apparatus and the current data moving direction It has the advantage that it can be easily understood.

  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 the present embodiment, when the front panel 25a is in the closed state, the inner display section 48 (fourth to sixth) provided on the housing surface exposed when the front panel is opened. Display sections 48a to 48c are arranged in a horizontal direction at a certain interval), a display / selection operation key, a push button 21a for taking out a B-CAS card, and a DVD disc The key operation including the button 31c for ejecting and the button 35c for ejecting the BD disc is controlled to be invalid. Further, as shown in FIG. 2 and FIG. 3 (c), a direction key having a function similar to the direction key of the remote controller RC in FIG. 7 (A) and a determination button are provided on the back surface 25b side of the front panel. An operation unit 61 and a switch 61b for starting and stopping the reproduction operation, each of which is semicircular and combined into a circle, and a reproduction switch 61b having a light emitting area on the circular outer periphery, and this reproduction The recording switch 61c is provided adjacent to the switch 61b and has the same shape. However, these operation key groups are also in a state where the front panel 25a goes from opening to closing and closing. It is controlled so as to be invalid in the state.

  The flow of the above operation will be described with reference to the flowchart of FIG. As shown in FIG. 8, first, when the power switch of the remote control device is turned on in step S1, it is detected whether the front panel is opened or closed in step S2. If the front panel is closed, the process proceeds to step S3, where an operation with an operation key provided on the front panel is accepted, but an operation key provided on the back surface of the front panel and the surface exposed to the housing when the front panel is opened. The operation by is invalid. Next, in step S4, it is monitored whether or not the front panel shifts from open to closed, and if a shift operation from open to closed is detected, the process proceeds to step S5. Moreover, also when the front panel is open in step S2, the process proceeds to step S5. In step S5, an operation with an operation key provided on the surface exposed to the housing when the back surface of the front panel and the front panel are opened is accepted, but an operation with the operation key provided on the front panel is invalidated. Next, in step S6, it is monitored whether or not the front panel shifts from open to closed, and if a shift from open to closed is detected, the process returns to step S3. Thereafter, the same operation is repeated.

  As described above, in the recording / reproducing apparatus according to the present embodiment, an operation key that cannot be operated in the operation unit or an operation key that is predicted to be unable to be operated in response to detection of opening / closing of the front panel. For example, when the front panel is closed, when a foreign object is caught between the front panel and the case, or when the front panel is opened, It is possible to prevent malfunctions such as operation keys that may occur when a foreign object is placed on the screen.

  In this embodiment, the front panel has been described as an example, but it is convenient to perform the same control even when there is a panel on the back side or when there is a panel on the side surface, and the position of the panel is limited. However, it goes without saying that even if the positions of the panels are different, they fall within the scope of the present invention.

  In the present embodiment, a two-tray recording / reproducing apparatus including one HDD device and two optical disk devices has been described as an example. However, a recording / reproducing apparatus having a front panel configuration may be used. For example, the same control can be performed regardless of the presence / absence and number of optical disk devices and HDD devices.

  The present invention can be used as a technique for preventing erroneous operation of a recording / reproducing apparatus. Further, the present invention can be applied to AV electronic equipment other than the recording / reproducing apparatus.
