In the configuration described in Patent Document 2 or 3 above, since the tray source is provided in a different location it is necessary to ensure space for arranging the light source such as in the housing, the size of the order device In addition, since it is necessary to provide a prism and a reflecting plate which are separate members from the tray, there is a problem that the cost increases. Further, since the light source is fixed on the inner upper part of the housing, it is difficult to obtain a light quantity sufficient to clearly indicate the disk arrangement area (disk mounting portion) when the tray is ejected.

  In the configuration described in Patent Document 1 or 4, the light source is provided in the tray, but it can emit light only in the vicinity of the light source, and it is difficult to illuminate the entire disk mounting portion or the entire tray. is there. The disk mounting unit is usually configured to be able to place two types of large and small disks with different diameters at a fixed position, but it is difficult to determine the arrangement position of the two types of large and small disks in a dark place with a conventional device. It is.

  Furthermore, in the state where the tray is inserted into the housing, it is not possible to recognize the presence or type of the disk. This type of apparatus includes a display unit made up of a liquid crystal panel, etc., and the display unit includes the presence / absence of a disk, type (CD, DVD, etc.), operation state of the drive unit in the housing such as playback operation and recording operation (PLAY, REC, etc.) ) Is displayed as characters, but the displayed characters are small and extremely difficult to see from a distance. In the case of in-vehicle use, confirmation of display characters is likely to hinder driving, so improvement has been desired.

  The present invention has been made in view of the circumstances as described above, and an object of the present invention is to provide a disk drive device that can illuminate the disk mounting portion of the tray without incurring the increase in size and cost of the device as much as possible. That is. Another object is to provide a disk drive device that can illuminate the entire disk mounting portion or the entire tray and has an excellent illumination effect.

In order to achieve the above object, the present invention provides a disk drive device for driving a disk (D), a housing (1), and disk mounting portions (7, 8, 70, 80, 72, 82) and a tray (6, 60, 62) formed of a light transmissive material that is movable in the ejecting direction and the inserting direction with respect to the casing, and the insertion into the disc mounting portion. When the tray is inside the tray on the direction side and the tray is ejected from the housing, it is mounted at a position hidden inside the housing , emits light in the ejection direction of the tray, and emits the light. wherein the benzalkonium provided with a light source (11) for emitting the tray by conduction to the interior of the insertion direction over to the discharge direction from the side the light transmitting material relative to the disk mounting portion of the tray Be Providing disk drives.

Here, it is preferable that the tray has a bright portion (12) that intensively emits the light emitted from the light source to the outside.

  It is preferable that the bright portion includes a front end portion (6A, 60A, 62A) of the tray in the discharge direction. Moreover, it is preferable that the said brightness | luminance part contains the outer periphery (7A, 8A, 70A, 70B, 71, 80A) of the said disk mounting part.

  Further, it is preferable that the plate thickness of the tray gradually decreases from the insertion direction side of the tray toward the discharge direction side.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
<First Embodiment>
FIG. 1 is a schematic perspective view showing a disk drive apparatus according to the first embodiment. The apparatus in the illustrated example is a CD player that reproduces recorded information on a CD as a disk. On the front surface of the disk drive device housing (including the exterior and other internal chassis) 1, an operation switch 3 for giving a specific control signal to an internal control circuit as an operation unit 2, an operating state of the control system, and the like are shown. A display unit 4 and a slit-shaped opening 5 are provided. In addition to the main power switch, the operation switches 3 include a disk drive start button, a song selection head, a pause, an eject switch (for ejecting the disk), and the like. The tray 6 is provided so as to be able to be taken in and out from the opening 5, and a disk D to be reproduced is placed on the tray 6.

  According to such a disk drive device, a desired disk D is placed on the tray 6 that extends horizontally from the opening 5, and the disk D is loaded into the housing 1 by pushing the tray 6 to reproduce recorded information. Can be executed. When the disk D is replaced, the disk D can be ejected from the opening 5 to the outside of the housing 1 while being placed on the tray 6 by pressing the eject switch.

  FIG. 2 is a plan view showing the tray 6. In FIG. 2, the entire tray 6 is formed of a light transmissive material (transparent material) such as acrylic resin or polycarbonate. The entire tray 6 is preferably uniformly transparent, but part or all of the tray 6 may be translucent. Reference numerals 7 and 8 denote disk mounting portions formed of concentric concavities. Out of these, the outer disk mounting portion 7 has a large-diameter disk (a CD having a diameter of 12 cm in this example) arranged in a fitted state, and on the inner side thereof. A small-diameter disk (a CD having a diameter of 8 cm in this example) can be placed in a fitted state on the disk mounting portion 8 provided. Unless otherwise distinguished, the large-diameter disk and the small-diameter disk are collectively referred to as a disk D.

Further, a notch hole 9 is formed in the central portion of the tray 6 from the center portion of the disk mounting portions 7 and 8 to the rear portion in the ejection direction (that is, the direction of the housing 1). The notch hole 9 is for irradiating a laser beam from below the disc D placed on the disc mounting portions 7 and 8 on the information recording surface. Notch hole 9 move in the radial direction of the disk D while transmitting and receiving the laser beam. In here it formed along a moving path of the optical pickup (not shown), at one end of the notch hole 9 and is able to pass through a turntable to be described later for supporting the lower surface center portion of the disc D.

  Further, two light source mounting portions 10 (rectangular holes in this example) are formed in the tray 6 at the rear portion (insertion direction side) of the disk mounting portions 7 and 8. The light source mounting portion 10 is provided with a light source 11 made of a light emitting diode facing the front end surface, and is used for illumination from the light source 11 toward the front of the tray 6 in which the disk mounting portions 7 and 8 are formed. The light is emitted. Here, since the tray 6 is light transmissive, the light emitted from the light source 11 enters the inside of the tray 6 from a direction orthogonal to the thickness direction of the tray 6, and the incident light is inside the tray 6. In other words, a part of the incident light is transmitted through (that is, the inside of the light-transmitting material) and radiated externally from the rear outer peripheral edges 7A and 8A of the disk mounting portions 7 and 8 having a step. Therefore, the rear outer peripheral edges 7A and 8A of the disk mounting portions 7 and 8 emit light with high brightness as the bright portion 12.

  Further, most of the light emitted from the light source 11 reaches the front end 6A of the tray 6 in the discharge direction, and is also radiated intensively from here. Therefore, the front end 6 </ b> A in the discharge direction of the tray 6 also emits light with higher brightness than the other parts as the bright part 12. For this reason, an illumination effect is obtained in a dark place, and the front and back of the disk mounting portions 7 and 8 emit light with high brightness as the radiant portion 12, thereby clarifying the position where the disk D is to be disposed even in the dark place.

  In addition, if it is a surface that intersects at a predetermined angle (about 30 degrees) or more with respect to the traveling direction of light, it can be a bright portion 12 that emits light in the viewing direction and emits light with high brightness, but this is limited to a plane It can also be formed with a curved surface.

  And according to 1st Embodiment, the discharge direction front end part 6A of the tray 6 which forms the bright part 12 is provided in the opposing state with the light source 11 on both sides of the disk mounting parts 7 and 8, and is emitted from the light source 11. Since the light passes through the inside of the light transmissive material from the insertion direction side to the discharge direction side with respect to the disk mounting portions 7 and 8 of the tray 6 and reaches the front end portion 6A in the discharge direction, the entire tray 6 is slightly light. Emits light. Furthermore, the optical perception effect of the disc mounting portions 7 and 8 is increased by the rear outer peripheral edges 7A and 8A of the disc mounting portions 7 and 8 and the front end portion 6A in the ejection direction acting as the bright portion 12.

  In this example, the following configuration is preferable. In order to intensively emit the front end portion 6A of the tray 6 in the discharge direction as the bright portion 12, the taper of the tray 6 gradually decreases from the rear side in the discharge direction to the front as shown in FIG. In addition, a hole for inserting a finger or the like is not formed between the front end 6A in the discharge direction of the tray 6 and the light source 11 to prevent light from leaking, and the surface of the tray 6 has a mirror surface with less unevenness. Prevents light attenuation.

  Further, at the front end portion 6A in the discharge direction of the tray 6, as shown in FIG. 4, a ridge 12A perpendicular to the plate surface of the tray 6 is formed as the brilliant portion 12, and the radiated light is scattered on the ridge 12A. In addition to the shape, in order to efficiently guide the light from the light source 11 into the ridge 12A, a slope 12B for refracting light is formed below the ridge 12A.

  On the other hand, as shown in FIG. 5, a rack 13 and a guide groove 14 are formed in parallel on the rear side edge of the tray 6. A pinion (not shown) provided inside the housing 1 is engaged with the rack 13, and a pin (not shown) is inserted into the guide groove 14. With this configuration, the tray 6 is moved back and forth (in the discharge direction and the insertion direction with respect to the housing 1) while being kept in a horizontal state by the rotational drive of the pinion so that the tray 6 can be moved in and out of the housing 1.

  FIG. 6 shows a state in which the tray 6 is retracted into the housing 1 and stored. At this time, the center of the disk D arranged in the disk mounting portions 7 and 8 is the turntable 15 and a clamp disk facing the turntable 15. It matches the position of 16. When the disk D is reproduced, the center of the disk D is sandwiched between the turntable 15 and the clamp board 16 by the floating of the turntable 15, and the disk D is at a position slightly separated from the disk mounting portions 7 and 8. Will be rotated. In FIG. 6, reference numeral 17 denotes a circuit board for lighting the light source 11, which is fixed to the inside of the housing 1 below the tray 6 so as not to obstruct the movement of the tray 6 with the light source 11. They are connected by a flexible energizing member 18 (band-shaped flexible printed wiring). In other words, the flexible energization member 18 is flexible, and the length is determined in consideration of the amount of movement of the tray 6, and the necessary electric power is maintained while being connected to the light source 11 when the tray 6 is discharged. Can be supplied.

  Further, as is apparent from FIG. 6, when the tray 6 is stored, the front end 6A (bright portion 12) in the discharge direction is located at the front opening 5 of the housing 1 and is exposed to the outside. Yes. Therefore, even when the tray 6 is stored, an excellent illumination effect can be obtained by lighting the position of the opening 5 by turning on the light source 11.

On the other hand, FIG. 7 shows a state in which the tray 6 is ejected. At this time, the front portion of the tray 6 including the disk mounting portions 7 and 8 protrudes from the opening 5, and the rear portion of the tray 6 including the light source mounting portion 10 is the housing. Left inside the body 1. For this reason, even when the tray 6 is ejected, the light source 11 does not appear outside and is hidden in the housing 1 so as not to impair the beauty. In addition, when the tray 6 is discharged, the illuminating portion 12 including the front end portion 6A in the discharging direction emits light with high luminance when the light source 11 is turned on, so that an illumination effect is exhibited. In particular, the front and rear (front end 6A of the tray 6 in the discharge direction of the tray 6 and the rear outer peripheral edge 7A, 8A) of the disk mounting portion emit light with high brightness, as described above, and the disk mounting portion 7 and 8 that form the bright portion 12 emit light. Since the inner regions of the portions 7 and 8 also emit light with low luminance, the disk can be easily placed and removed even in a dark place.
Second Embodiment
The tray 6 only needs to include the light source 11 and the bright portion 12 corresponding thereto, and the overall form is not limited to the first embodiment, and may be changed to the second embodiment as shown in FIG. 8, for example. Since the second embodiment is different from the first embodiment only in that the tray 60 shown in FIG. 8 is used instead of the tray 6 in the first embodiment, only the tray 60 will be described, and other description will be omitted. . In FIG. 8, parts that are substantially the same as those in FIG.

  In FIG. 8, the front end portion 60A in the discharge direction of the tray 60 is a first embodiment in that it is a bright portion 12 including a polygonal ridge 120A and an inclined surface 120B for guiding light from the light source 11 to the ridge 120A. Although the form is the same, the front end portion 60A in the discharge direction of the tray 60 in the second embodiment is not the arc shape but the linear bright portion 12. In FIG. 8, the disc mounting portion 70 is provided on the rear outer peripheral edges 70 </ b> A and 70 </ b> A composed of arcuate wall surfaces partially raised from the rear side of the tray 60 in the discharge direction, and on the front side of the tray 60 in the discharge direction. The protrusions 70B and 70B are formed so that the peripheral edge of the large-diameter disk is supported inside the rear outer periphery 70A and the protrusion 70B. Further, an arc groove 71 passing through the position of the protrusion 70B is formed at the front part in the discharge direction of the tray 60, and the arc groove 71 is arranged along the peripheral edge of the disc disposed in the disc mounting portion 70. The protrusion 70B and the arc groove 71 form the front outer periphery of the disc mounting portion 70.

  Also in this example, the light source 11 is provided at the rear of the tray 60 in the discharge direction, and the light emitted from the light source 11 is transmitted through the inside of the tray 60 made of a light-transmitting material to the rear of the disk mounting portions 70 and 80. The outer peripheral edges 70A, 80A, the projections 70B, the circular arc grooves 71, and the tray 60 are radiated intensively from the front end 60A in the discharge direction. That is, in the second embodiment, the rear outer peripheral edges 70A and 80A of the disk mounting portions 70 and 80, the front surface portion of the protrusion 70B, the surface on the light source 11 side in the arc groove 71, and the front end portion 60A in the discharge direction of the tray 60 are The luminous part 12 emits light incident on the tray 60 from the light source 11 intensively to the outside and emits light with higher brightness than other parts.

In the second embodiment, since the arc groove 71 is provided on the outer periphery of the front portion of the disk mounting portion 70, the arc groove 71 is compared with the case where a wall surface similar to the wall surface 70A is provided on the outer periphery of the front portion. The part emits light with higher brightness. Accordingly, since both the wall surface 70A at the outer peripheral edge of the disc mounting portion 70 and the arc groove 71 at the outer peripheral edge of the front portion emit light with high brightness, the optical visual recognition effect of the disc mounting portions 70 and 80 is improved compared to the first embodiment. Further can be obtained.
<Third Embodiment>
Next, a third embodiment will be described with reference to FIG. Since the third embodiment is different from the first embodiment only in that a tray 61 shown in FIG. 9 is used instead of the tray 6 in the first embodiment, only the tray 61 will be described and the other description will be omitted. . In FIG. 9, parts that are substantially the same as those in FIG.

  In FIG. 9, 21 </ b> A is a light source corresponding to the disk mounting portion 7, and 21 </ b> B is a light source corresponding to the disk mounting portion 8. The light sources 21A and 21B are, for example, organic EL (electroluminescence) sheets, and are attached to the bottom surfaces of the disk mounting portions 7 and 8 with an adhesive or the like. An inorganic EL sheet or other light emitter sheet may be used instead of the organic EL sheet. Thus, by using the sheet-like light sources 21A and 21B, the disk mounting portions 7 and 8 emit light in a planar shape.

Light sources 21A and 21B having different emission colors are used, and the disk mounting portions 7 and 8 emit light in different colors. The light source 21 </ b> A is attached in a ring shape to the inner peripheral portion of the disc mounting portion 7 (the inner side of the disc mounting portion 7 and the outer portion of the disc mounting portion 8) excluding the disc mounting portion 8. Further, the light sources 21A and 21B are also connected to the circuit board 17 fixed inside the housing 1 by the flexible energizing member 18 as shown in FIG. Therefore, by turning on the light sources 21A and 21B when the tray 61 is ejected, the disk mounting portions 7 and 8 can be illuminated with different colors and their positions can be clearly indicated even in the dark. In the third embodiment, the tray 61 is not required to be formed of a light transmissive material. Further, light emitting diodes may be used as the light sources 21A and 21B, and these may be embedded in the periphery of the disk mounting portions 7 and 8 at a predetermined interval.
<Fourth embodiment>
The fourth embodiment includes the same tray as the first and second embodiments, and is configured to easily recognize at least one of the presence / absence and type of the disk D on the tray and the operating state of the apparatus. It is. In the fourth embodiment shown here, instead of the tray 6 in the first embodiment, as in the second embodiment, as shown in FIG. 10 and FIG. 62 is used. It may be arcuate like the tray 6 of the first embodiment. Note that, in FIG. 11, parts that are substantially the same as those in FIG. In the fourth embodiment, descriptions of common parts with the first embodiment will be omitted as appropriate.

  In FIG. 11, the entire tray 62 is formed of a light transmissive material (for example, a transparent material made of acrylic resin or polycarbonate). The front end portion in the discharge direction of the tray 62 is a light radiating portion 62A for radiating light from the light source 11 to the outside, and the light radiating portion 62A is attached to and detached from the tray main body 62B forming the disk mounting portions 72 and 82. It is supposed to be free. A cutout hole 92 is formed in the center of the tray main body 62B from the center of the disk mounting portions 72 and 82 along the radial direction thereof.

  In the tray 62 shown in FIG. 11, the light emitted from the light source 11 enters the inside of the tray 62 from a direction orthogonal to the thickness direction of the tray 62, and the incident light is transmitted through the inside of the tray 62. A part of the light is radiated intensively from the outer peripheral edges of the rear portions of the disk mounting portions 72 and 82 having steps. In addition, as shown in FIG. 12, most of the light emitted from the light source 11 reaches the front end portion (light emitting portion 62A) of the tray 62 in the discharge direction, and the light from the light source 11 is also concentrated from the light emitting portion 62A. Radiated externally. Therefore, the rear outer peripheral edges of the disk mounting portions 72 and 82 and the light emitting portion 62A emit light with high luminance.

The tapered shape of the tray 62 shown in FIG. 12 is preferably set within a range of an inclination (angle) at which the light emitted from the light source 11 is totally reflected between the front surface and the back surface of the tray 62. Thereby, the light emitted from the light source 11 can be guided to the light emitting portion 62A while being totally reflected and condensed between the front surface and the back surface of the tray 62. As the taper shape of the tray 62, an angle may be formed not only on one side as shown in the illustrated example but also on both sides with respect to the moving direction of the tray 62. It is desirable that the angle is continuously given from the vicinity of the light source 11 toward the light emitting unit 62A, but this may be given intermittently.

  In short, the tray 62 is formed so that the thickness gradually decreases from the vicinity of the light source 11 toward the discharge direction front end portion (light emitting portion 62A), and at least the thickness T1 near the light source 11 as shown in FIG. It is only necessary that the thickness T2 on the side of the radiating portion 62A is small and T1 / T2> 1. T1 / T2 is the light collection magnification.

  As shown in FIG. 13, the configuration of the back side of the tray 62 is the same as that shown in FIG.

  FIG. 14 shows a state in which the tray 62 is retracted and stored in the housing 1. At this time, the center of the disk D placed on the disk mounting portion 72 is the turntable 15 and the clamp disk 16 facing the turntable 15. It matches the position of. When the disk D is reproduced, for example, the center of the disk D is sandwiched between the turntable 15 and the clamp board 16 due to the floating of the turntable 15. The signal of the disk D is read by the optical pickup 150 moving in the radial direction while the disk is rotated at a position slightly separated from the disk mounting portion 72. The turntable 15 and the optical pickup 150 constitute a drive unit 155 that performs a reproducing operation and a recording operation on the disk D.

  In FIG. 14, reference numeral 160 denotes a control unit (microcomputer) that constitutes a control circuit that controls the drive unit 155 and the light source 11. The control unit 160 is fixed inside the housing 1 below the tray 62. The light source 11 is connected by a strip-like flexible energizing member 18 so as not to hinder the movement of the tray 62.

  As is apparent from FIG. 14, when the tray 62 is inserted into the housing 1, the light emitting portion 62A forming the front end portion in the discharge direction is located at the opening 5 on the front surface of the housing 1 and exposed to the outside. It is like that. Further, the light emitting portion 62A forms a ridge 180 that seals the opening 5, and prevents dust and the like from entering the housing 1. The light emitting unit 62A emits light from the light source 11 to the outside of the housing 1 to shine the position of the opening 5 and exhibits an excellent illumination effect.

  In the fourth embodiment, the light emitters constituting the light source 11 are controlled to emit light based on predetermined control information. The control information includes specific identification information (for example, the type of the disk) recorded on the disk D, the presence / absence of the disk D on the tray 62 inserted into the housing 1, the size of the disk D, and the position of the tray 62. Information (discharge position / insertion position / moving) and operation state of the drive unit 155 (reproduction operation / recording operation / pause / position information of the optical pickup, etc.) can be used.

  Control information for controlling light emission of the light source 11 includes specific identification information recorded on the disk D, presence / absence of the disk D on the tray 62, size of the disk D, position information of the tray 62, and operation of the drive unit 155. Any one of the states may be used, and any two or more may be appropriately combined.

  As shown in FIG. 15, the light source 11 is composed of a plurality of light emitters 11A, 11B, and 11C having different emission colors (in this example, three-color LEDs composed of three types of red LED, green LED, and blue LED), By individually controlling the light emission of each of the light emitters 11A to 11C based on the control information as described above, the light emitted from the light source 11 is changed to the light color of each of the light emitters 11A to 11C and various colors obtained by combining the light colors. Can be changed. Thus, the light-emitting body does not have to be independent for each color, and may be, for example, one that is sealed and integrated with a resin or the like.

Additionally, or constituting the light source 11, for example in two colors of red LED and green LED, may or configure a single color the LED. In the case of a single-color LED, the blinking cycle and emission luminance (light intensity) may be changed based on the control information.

  On the other hand, the controller 160 stores the control information as described above obtained from the optical pickup 150 and the sensor 19 provided in the housing 1, and the light source 11 based on the control information stored in the RAM 20. A ROM 21 for storing a program for performing light emission control is provided, and the control unit 160 constitutes a light source control means. The sensor 19 is based on at least one of the presence / absence of the disk D on the tray 62, the size of the disk D, specific identification information recorded on the disk D, the position information of the tray 62, and the operating state of the drive unit 155. It operates as a control information generating unit that generates control information.

  In the RAM 20, as specific identification information recorded on the disk D, for example, the type (CD, DVD, etc.) of the disk D recorded in the inner peripheral lead-in area of the disk D, the title of a song or movie, or the artist name, etc. In addition to the TOC (Table of content) information being input via the optical pickup 150, the presence or absence of the disk D in the housing 1, the size, the position information of the tray 62, the operating state of the drive unit 155, and the like are detected by the sensor 19. Is input through.

  Then, according to the control unit 160, the light emitters 11 </ b> A to 11 </ b> C of the light source 11 are individually controlled to emit light based on the specific control information recorded on the disk D and the control information such as the operation state of the drive unit 155. The light emission pattern such as the color of light emitted from the light source 11, its blinking cycle, and luminance (light intensity) can be changed. As an example, FIG. 16 shows a flow of processing by the control unit 160.

  In FIG. 16, when the processing of the program stored in the ROM 21 is started, the control unit 160 determines whether or not there is an instruction to eject the tray 62 at step S1, and if there is an instruction to eject the tray 62, the tray at step S2. 62 is ejected. If there is no instruction to eject the tray 62, the process proceeds to step S5. The controller 160 determines whether or not there is an instruction to store the tray 62 in step S3, and if there is an instruction to store the tray 62, stores the tray 62 in step S4 and proceeds to step S5. If there is no instruction to store the tray 62, the process returns to step S3.

  The controller 160 determines whether or not the disk D is present in step S5. If it is determined that there is no disk D, the light source 11 is turned off in step S6 and the process returns to step S1. If it is determined that there is a disk D, the type of the disk D is determined in step S7. In step S7, it is determined whether it is a CD or a DVD based on the TOC information. If it is a CD, the controller 160 turns on the red LED of the light source 11 in step S8, and if it is a DVD, it turns on the blue LED of the light source 11 in step S9.

  Through the above processing, the user can easily recognize whether or not a disc is inserted in the housing, and if a disc is inserted, whether a CD is inserted or a DVD is inserted. Can do.

  Furthermore, the control unit 160 determines the operation state of the drive unit 155 in step S10, and returns to step S1 in a non-operation state that is neither a reproduction operation state nor a recording operation state. If it is in the reproduction operation state, the green LED of the light source 11 blinks in step S11. If it is in the recording operation state, the red LED and the green LED of the light source 11 are combined and blinked in yellow in step S12. Return to. Note that in the state of blinking green in the reproduction operation state and blinking yellow in the recording operation state, the process proceeds to step S10 as it is without performing the process of transition to step S8 or S9 in step S7.

  If the blinking cycle and the luminance change cycle of the light source 11 are irregularly changed with 1 / f fluctuation, a relaxation effect can be obtained in addition to the illumination effect. The 1 / f fluctuation means fluctuation (variation) having a characteristic that the slope of the power spectrum is −1 when the vertical axis represents the intensity of the power spectrum and the horizontal axis represents the frequency as a logarithmic value.

  Returning to FIG. 15, a user setting table is provided in the RAM 20 of the control unit 160, and the user himself / herself inputs the light emission pattern (light color / flashing cycle / brightness) of the light source 11 from the remote controller 22 or the like according to the song title or artist name. It is also possible to input a setting to the user setting table via 23. The control unit 160 identifies the title and artist name of the song based on the TOC information recorded on the disc D, and causes the light source 11 to emit light with the light emission pattern set in the user setting table.

  Further, the light source provided in the tray 62 is configured by a light emitter similar to the light source 11 provided in the tray 62 as the backlight of the display unit 4 illustrated in FIG. 10, and the light emission control of the light emitter is controlled by the control unit 160. You may comprise so that it may synchronize with 11 light emission control.

  In the first to fourth embodiments described above, an optical disk such as a CD, CD-R, or DVD is taken as an example of the disk D, but it may be a magneto-optical disk. It can be applied to a recording / reproducing apparatus. Furthermore, the present invention can be applied to a recording / reproducing apparatus for any information recording medium.
