Description

  The present invention relates to an in-vehicle disc player that records and / or reproduces information on a disc such as a CD or a DVD, and more particularly, to a slot-in type in-vehicle disc that automatically conveys the disc between a disc insertion slot and a play position. It relates to the player.

  In general, in an in-vehicle disc player, a drive chassis having a frame having a disc insertion slot, a disc guide arranged at the upper end of the drive chassis, and a swingable arrangement below the disc guide are provided. The roller bracket and a rubber roller rotatably supported by the roller bracket are sandwiched between the disk guide and the roller by rotating the roller in both forward and reverse directions using a motor as a drive source. A slot-in type disc transport mechanism that automatically transports a disc between an eject position (disc insertion slot) and a play position has been widely adopted (see, for example, Patent Document 1).

  In an in-vehicle disc player equipped with such a disc transport mechanism, when the disc is in an ejected state (standby state) in which the disc is not loaded in the apparatus main body, the roller bracket receives the spring force of the spring and receives the lower surface of the disc guide. The roller supported by the roller bracket is in contact with the lower surface of the disk guide at the rear position of the disk insertion slot, or is opposed through a slight gap. In such an ejected state, when a predetermined amount of the disc is inserted into the main body of the apparatus from the disc insertion opening by the user's manual operation, and the leading end in the insertion direction of the disc enters between the disc guide and the roller, Is automatically conveyed into the apparatus main body by the rotational driving force in one direction of the roller. When the disc is automatically conveyed above the play position in this way, the detection lever arranged at the back of the drive chassis is pressed against the tip in the insertion direction of the disc and is rotationally displaced. A mode switching operation is performed based on the dynamic displacement. As a result, the roller bracket rotates downward against the spring force of the spring, the roller moves away from the lower surface of the disk guide, the clamp arm that supports the clamper rotates downward, and the center of the disk moves to the clamper. It is chucked between the turntables and enters the play state. In this play state, the spindle motor is used as a drive source to rotate and rotate the turntable, the disc, and the clamper together, and the optical pickup is moved in the radial direction of the disc, thereby reproducing information from the disc. Is called.

  Further, when ejecting (ejecting) a disc that has been played back, the reverse operation is performed. In this case, the clamp arm in the lowered position first rotates upward, and after the chucking operation of the disk by the clamper and the turntable is released, the roller bracket rotates upward by the spring force of the spring. Then, the disk is in an ejection start state in which the disk is sandwiched between the disk guide and the roller. Thereafter, when the disc is automatically conveyed from the play position toward the disc insertion slot by the rotational driving force in the other direction of the roller, and when the rear end in the disc ejection direction is automatically conveyed to a position away from the roller, the disc is Since it stops at the position and the tip portion in the ejection direction protrudes from the disc insertion port by a predetermined amount, the user can grasp the disc protruding from the disc insertion port and take it out from the apparatus main body.

JP 2006-99833 A

  By the way, in the above-described conventional slot-in type in-vehicle disc player, the disc is sandwiched between a roller arranged in parallel to the disc insertion slot and a disc guide arranged opposite to the roller. Since the disc is automatically transported above the play position by the rotational driving force of the disc, the detection lever etc. is rotated and displaced at the tip in the disc insertion direction to shift to the clamping operation. If it is too far from the play position, the detection lever or the like cannot be operated by the transport force of the disc at the play position. For this reason, the roller is arranged at a position that is inward (rear) from the front end of the drive chassis facing the disk insertion slot. Accordingly, the separation distance between the roller and the disk insertion slot is accordingly increased. Therefore, the ejection amount (protrusion amount) of the disc protruding from the disc insertion opening during the ejection operation is reduced, and there is a problem that it is difficult for the user to remove the disc from the apparatus main body.

  The present invention has been made in view of the actual situation of the prior art, and an object of the present invention is to provide a slot-in type in-vehicle disc player that can easily take out a disc from a disc insertion slot during an eject operation. It is in.

  In order to solve the above-described problems, the present invention includes a roller installed obliquely from the vicinity of the center of the disk insertion slot toward the outer side, and the conveyance force in the oblique direction generated as the roller rotates. Of these, the disc is automatically transported between the disc insertion slot and the play position by utilizing a component force directed in a direction orthogonal to the disc insertion slot.

  The in-vehicle disc player of the present invention includes a roller installed obliquely from the vicinity of the center portion of the disc insertion slot toward the outer side, and the disc is automatically sandwiched between the disc guide and the roller by such a roller. Since the area that can be transported expands along the direction of the disc transport path, even if the disc ejected from the disc insertion slot is set to be discharged, the clamping operation is reliably performed using the disc transport force at the play position. Thus, the user can easily remove the disc from the disc insertion slot during the ejection operation.

It is the perspective view which looked at this drive unit from the back side. It is explanatory drawing which shows the state in the middle of conveyance of a disk. It is explanatory drawing which shows the state by which the disc was automatically conveyed to the play position. It is explanatory drawing which shows the conveyance force generate | occur | produced with respect to a disk from a roller. It is explanatory drawing of the vehicle-mounted disc player which concerns on 2nd Example of this invention.

  In one embodiment of the present invention, a frame having a disk insertion slot on the front surface, a disk transport mechanism for automatically transporting a disk inserted from the disk insertion slot between the disk insertion slot and a play position, and an insertion A drive mechanism for chucking and rotating the disc at the play position, and the disc transport mechanism includes a roller capable of rotating in both forward and reverse directions, and a disc guide disposed above the roller. In a vehicle-mounted disc player in which the disc sandwiched between the disc guide and the roller is automatically conveyed by the rotational driving force of the roller, the rollers are obliquely opposite to each other in the disc conveyance direction. A first roller and a second roller extending in the direction of the first and second rollers, and one end of each of the first and second rollers is connected to the first roller. And the configuration that is connected in a plan view V-shape in the vicinity of the central portion of the disk insertion opening.

  In the in-vehicle disc player configured as described above, the disc 2 moves in an oblique direction opposite to each other in accordance with the rotation of the first roller and the second roller coupled in a V shape in plan view. Two types of transport force are generated, and the component force in the direction parallel to the disc insertion slot is canceled out of these two types of transport force, but the disc is inserted by each component force in the direction perpendicular to the disc insertion slot. It can be automatically conveyed between the mouth and the play position. As a result, the area in which the disc can be automatically transported by being sandwiched between the disc guide and the roller expands along the disc transport path direction, so even if the disc ejection amount protruding from the disc insertion slot is set to be large, It is possible to reliably shift to the clamping operation using the disc conveying force at the position, and the user can easily take out the disc from the disc insertion slot during the ejection operation.

  In another embodiment of the present invention, a frame having a disc insertion slot on the front surface and a disc transport mechanism for automatically transporting a disc inserted from the disc insertion slot between the disc insertion slot and a play position. A drive mechanism that chucks the inserted disk at the play position and rotationally drives the disk, and the disk transport mechanism has a roller that can rotate in both forward and reverse directions, and a disk that is opposed to the roller. In an in-vehicle disc player in which a disc sandwiched between the disc guide and the roller is automatically conveyed by the rotational driving force of the roller, the guides are arranged in parallel to each other via a disc conveyance path. A pair of transport guide members are provided, and the roller is directed from the vicinity of the center of the disk insertion slot toward one of the transport guide members. Was the configuration that is installed diagonally Te.

  In the in-vehicle disc player configured as described above, a conveying force is generated to move the disc in an oblique direction and press it against the conveying guide member as the roller rotates. The disc can be automatically conveyed between the disc insertion slot and the play position using the component force in the direction orthogonal to the disc. As a result, the area in which the disc can be automatically transported by being sandwiched between the disc guide and the roller expands along the disc transport path direction, so even if the disc ejection amount protruding from the disc insertion slot is set to be large, It is possible to reliably shift to the clamping operation using the disc conveying force at the position, and the user can easily take out the disc from the disc insertion slot during the ejection operation.

  First, an in-vehicle disc player according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 6. As shown in FIG. 1, the in-vehicle disc player according to the present embodiment includes an outer shell of a main unit. And a drive unit 2 housed inside the frame 1. The drive unit 2 is elastically supported by the frame 1 via a plurality of dampers 3 and springs (not shown). ing. A horizontally long disk insertion slot 4 is formed in the front plate 1a of the frame body 1, and lock pins 5 project inwardly on both the left and right inner walls of the frame body 1. In addition, an inclined plate 1 b is bent on the front plate 1 a, and the inclined plate 1 b extends from the center of the lower side of the disk insertion slot 4 toward the inner bottom surface of the frame 1 in a forward inclined posture.

  As shown in FIGS. 2 and 3, the drive unit 2 includes a synthetic resin base member 6, and a metal support plate 7 is fixed to the front upper surface of the base member 6 with screws. A synthetic resin guide top 8 is integrated with the lower surface of the support plate 7 by a snap joint or the like, and a disk is conveyed between the guide top 8 and the inner bottom surface of the base member 6 so as to face the disk insertion opening 4. A space is defined. A first roller 9 and a second roller 10 made of rubber are disposed inside the disk transport space, and one end of each of the first and second rollers 9 and 10 is connected via a universal joint 11. They are connected in a V shape in plan view. In the case of the present embodiment, the second roller 10 is a driving side roller that rotates by receiving the driving force of the motor 12 disposed at the back of the base member 6, and the first roller 9 is a universal joint. 11 is a driven roller that rotates synchronously with the second roller 10 via 11. However, conversely, the first roller 9 may be a driving roller, and the second roller 10 may be a driven roller. The universal joint 11 is composed of a cardan joint, a Rzeppa joint, or the like, and this universal joint 11 is positioned immediately above the inclined plate 1 b behind the center of the disk insertion port 4. The other end portions of the first roller 9 and the second roller 10 are rotatably supported on the rear end portion of the roller bracket 13, and the front end portion of the roller bracket 13 is rotatable on the base member 6. It is pivotally supported. That is, the first and second rollers 9 and 10 generally have a shape in which the central portion of one roller is bent in a V shape, and the universal joint 11 provided at the bent portion is a disk insertion slot 4. The two side portions are rotatably supported by the roller bracket 13 at positions relatively distant from the disc insertion opening 4.

  A spring (not shown) is stretched between the roller bracket 13 and the bottom surface of the base member 6. The roller bracket 13 causes the first and second rollers 9, 10 to move between the guide top 8 and the elastic force of the spring. It is biased in the direction approaching the lower surface. A pin (not shown) is provided at the rear end of the roller bracket 13, and the pin is inserted into a cam hole of a slide member, which will be described later, so that the roller bracket 13 is moved as the slide member moves forward and backward. It is designed to rotate around. The guide top 8, the first and second rollers 9 and 10, and the roller bracket 13 constitute a disk transport mechanism.

  The left and right rear ends of the clamp arm 14 are pivotally supported on the rear wall of the base member 6, and a clamper 15 is rotatably supported on the front side of the central portion of the clamp arm 14. In addition, a slide member 16 made of synthetic resin is disposed outside the left and right side walls of the base member 6, and both the slide members 16 are supported so as to be movable in the front-rear direction (X1-X2 direction) of the base member 6. Has been. Both slide members 16 are connected via a link member 17 disposed on the back side of the base member 6. When one slide member 16 moves forward and backward using the motor 12 as a drive source, the slide member 16 is synchronized with the movement. The other slide member 16 is also moved forward and backward. A leaf spring 18 is fixed in a cantilever manner to the lower surface of the front end portion of one slide member 16, and an upright piece 18 a is bent at a right angle at the distal end portion of the leaf spring 18. The upright piece 18a slides on the inclined plate 1b as the slide member 16 moves forward and backward. When the slide member 16 is in the retracted position and the upright piece 18a is in contact with the lower portion of the inclined plate 1b, The leaf spring 18 is not elastically deformed as shown by the solid line in FIG. 2, but when the upright piece 18a rides on the upper part of the inclined plate 1b as the slide member 16 advances, the upright piece 18a rises and the universal joint 11 is lifted. The leaf spring 18 is elastically deformed upward as shown by a two-dot chain line in FIG.

  A spindle motor 19 and an optical pickup 20 constituting a drive mechanism are mounted on the back surface side of the base member 6, and a turntable (not shown) facing the lower surface of the clamper 15 is mounted on the rotating shaft of the spindle motor 19. Is fixed. Further, a power switching mechanism 21 including a planetary gear train, a lock lever, and the like (not shown) is disposed on the back surface side of the base member 6, and the driving force of the motor 12 is first and The operation can be switched to one of the operations of the second rollers 9 and 10, the slide member 16, and the optical pickup 20. Further, the rotating arms 22 are rotatably supported on the left and right side walls of the base member 6, and the pins 22 a protruding from the rotating arms 22 are inserted into the engaging holes 16 a formed in the slide member 16. Has been. Then, as the slide members 16 move forward and backward, the pin 22a moves in the engagement hole 16a, so that the rotation arm 22 is bent on the left and right side walls of the frame 1 and a lock plate (not shown). I am going to engage and disengage.

  In addition to the engagement hole 16a, the slide member 16 is formed with a lock groove 16b, a cam hole and a projection (not shown), and the lock groove 16b is connected to the lock pin 5 as the slide members 16 move forward and backward. By engaging and disengaging, the lock switching mechanism that switches the drive unit 2 to the locked / unlocked state with respect to the frame 1 is operated. Further, as the slide members 16 move forward and backward, a pin (not shown) of the roller bracket 13 relatively moves in the cam hole, whereby the roller bracket 13 is rotated and the first and second rollers 9 and 10 are rotated. Can move up and down. Further, as the slide members 16 move forward and backward, the projections engage and disengage with cams (not shown) formed on both side walls of the clamp arm 14, thereby rotating the clamp arm 14 so that the clamper 15 becomes a turntable. On the other hand, it moves up and down.

  The operation of the in-vehicle disc player configured as described above will be described. When the disc D is ejected (standby state) when the disc D is not inserted into the main unit, both the slide members 16 are in the forward position on the front side of the base member 6. The lock groove 16b of the slide member 16 is engaged with the lock pin 5 of the frame body 1, and the rotating arm 22 engaged with the engagement hole 16a of the slide members 16 is a lock plate (not shown) of the frame body 1. Therefore, the drive unit 2 on which the entire mechanism such as the disk transport mechanism and the drive mechanism is mounted is in a locked state in which it is fixedly supported with respect to the frame 1. Further, in this ejected state, the projections (not shown) of both slide members 16 are in contact with the cam of the clamp arm 14, so that the clamp arm 14 is rotated upward and the clamper 15 is separated from the turntable. A space in which the disk D can be inserted is secured. Further, since a pin (not shown) of the roller bracket 13 is located at the upper position of the cam holes of both slide members 16, the roller bracket 13 is tilted forward with the rear end side supporting the first and second rollers 9 and 10 raised. The outer peripheral surfaces of both rollers 9 and 10 are pressed against the lower surface of the guide top 8 by receiving the elastic force of a spring (not shown). At this time, the upright piece 18a of the leaf spring 18 rides on the upper part of the inclined plate 1b formed on the front plate 1a, and the universal joint 11 connecting the first and second rollers 9 and 10 moves downward. Therefore, the first and second rollers 9 and 10 face the lower surface of the guide top 8 while maintaining a V-shaped posture in the horizontal plane.

  In this state, when the user picks up the disk D and inserts a predetermined amount into the main body of the apparatus through the disk insertion opening 4, the disk D passes through the disk transport space above the roller bracket 13 and the first and second rollers 9, 10. When the disk detection means (not shown) is operated by inserting the disk D during this time, the motor 12 rotates in one direction based on the signal from the disk detection means. Begin to. As a result, the first and second rollers 9 and 10 start to rotate in one direction by the driving force of the motor 12, and are sandwiched between the rollers 9 and 10 and the guide top 8 as shown in FIG. The disc D is automatically conveyed in the insertion direction (arrow X2 direction) by the rotational force of both rollers 9 and 10. During the automatic conveyance of the disk D, as shown in FIG. 6, the conveyance force F1 is generated in the direction perpendicular to the axis of the first roller 9 from the first roller 9 to the disk D, and the second A conveying force F2 is generated from the roller 10 with respect to the disk D in a direction orthogonal to the axis of the second roller 10. Here, if a straight line parallel to the disk insertion slot 4 is P, the first and second rollers 9 and 10 connected in a V shape are inclined at the same angle θ in the opposite direction to the straight line P. Therefore, the component force F1a in the direction parallel to the straight line P of the transport force F1 and the component force F2a in the direction parallel to the straight line P of the transport force F2 are canceled (offset), and the disk D is in contact with the straight line P of the transport forces F1 and F2. It is automatically conveyed in the direction of arrow X2 by the component forces F1b and F2b in the orthogonal direction.

  As shown in FIG. 5, when the disk D is automatically conveyed to the upper position of the play position (position where the center hole of the disk D is between the turntable and the clamper 15), Since the detection lever (not shown) arranged on the disk is pressed by the edge on the front end side in the insertion direction of the disk D and is rotationally displaced, and the power switching mechanism 21 is operated using the rotational displacement of the detection lever as a trigger, the motor 12 is switched from the first and second rollers 9 and 10 to the slide member 16, and both the slide members 16 move from the forward position to the backward position of the base member 6 using the motor 12 as a drive source. Even in such a play position, the rear end of the disc D in the insertion direction is sandwiched between the first and second rollers 9 and 10 and the guide top 8, and the first and second rollers 9 and 10 rotate. Since the driving force acts on the disk D, the detection lever can be reliably rotated and displaced by the conveying force of the disk D.

  Thus, while both slide members 16 move to the end position in the backward direction, the lock groove 16b of both slide members 13 is separated from the lock pin 5 and the pin 14a of the rotating arm 22 is engaged with the slide member 16. Since the engagement between the pivot arm 22 and a lock plate (not shown) is released by moving through the hole 16a, the base member 6 is in an unlocked state in which the base member 6 is elastically supported by the frame body 1 by a plurality of dampers 3 and the like. Become. Further, since a pin (not shown) of the roller bracket 13 moves from the upper position to the lower position of the cam holes of the slide members 16, the roller bracket 13 rotates downward against the elastic force of the spring, and the slide Since the upright piece 18a of the leaf spring 18 moves to the lower side of the inclined plate 1b and moves away from the lower surface of the universal joint 11 by the retreat of the member 16, the first and second rollers 9 and 10 supported by the roller bracket 13 are It descends without being disturbed by the upright piece 18a and leaves the lower surface of the disk D. At this timing, projections (not shown) of both slide members 16 are separated from the cam of the clamp arm 14, so that the clamp arm 14 that supports the clamper 15 rotates downward, and the center portion of the disk D is the clamper 15 and turntable. Clamped in between. Further, when the clamping operation of the disc D is completed, the power transmission path is switched by the power switching mechanism 21, and the driving force of the motor 12 is switched from the slide member 16 to the optical pickup 20 to enter the play state. In this play state, the spindle motor 19 is driven to integrally rotate the turntable, the disk D, and the clamper 15, and the optical pickup 20 is moved in the radial direction of the disk D by the driving force of the motor 12. As a result, an information reproducing operation for the disk D is performed.

  Further, when ejecting (ejecting) the disk D that has been reproduced, etc., the reverse operation is performed by turning on the eject button (not shown) and rotating the motor 12 in the other direction. In this case, first, after the clamp arm 14 in the lowered position is rotated upward to release the chucking operation of the disk D by the clamper 15 and the turntable, the roller bracket 13 is rotated upward by the elastic force of the spring. As a result, the disk D is in an eject start state in which the disk D is sandwiched between the guide top 8 and the first and second rollers 9 and 10. Thereafter, the first and second rollers 9 and 10 are rotated in the other direction using the motor 12 as a drive source, whereby the disc D is ejected from the play position shown in FIG. 5 toward the disc insertion slot 4 (arrow X1). When the rear end of the discharge direction of the disk D further approaches the disk insertion slot 4 side from the position shown in FIG. 4, the disk D is moved from the first and second rollers 9 and 10 at this position. The rotational drive force of is interrupted and stops. At that time, since the connecting portion (universal joint 11) of the first and second rollers 9 and 10 is disposed at a close position behind the center of the disk insertion port 4, the disk D protruding from the disk insertion port 4 The protrusion amount (discharge amount) is increased, and the user can easily grasp the disk D and easily remove it from the apparatus main body.

  When the disk D is automatically conveyed in the ejection direction in this way, the conveying force in the direction opposite to the arrows F1 and F2 in FIG. In this case as well, since the component forces in the direction parallel to the disc insertion opening 4 of both conveying forces are canceled in this case as well, the disk D is arrowed by the component forces in the direction orthogonal to the disk insertion port 4 of both conveying forces. Automatically conveyed in the X1 direction.

  As described above, in the in-vehicle disc player according to the present embodiment, the first roller 9 and the second roller 10 connected in a V shape through the universal joint 11 are used as disc transport rollers. Since the connecting portion of the first and second rollers 9 and 10 is disposed close to the rear of the central portion of the disc insertion slot 4, the disc D is turned in the opposite direction as the first roller 9 and the second roller 10 rotate. Two types of conveying forces F1 and F2 are generated to be moved in an oblique direction, and the disk D is ejected by the component forces F1b and F2b in the direction perpendicular to the disk insertion slot 4 among these conveying forces F1 and F2. And play position can be automatically conveyed. As a result, an area in which the disk D can be sandwiched between the guide top 8 and the first and second rollers 9 and 10 and can be automatically transported expands along the disk transport path direction (arrow X1-X2 direction). Even when the discharge amount of the disc D protruding from 4 is increased, it is possible to reliably shift to the clamping operation using the transport force of the disc D at the play position, and the user can remove the disc D during the ejection operation. It becomes easy to grasp and can be easily taken out from the apparatus main body.

  Next, an in-vehicle disc player according to a second embodiment of the present invention will be described with reference to FIG. In FIG. 7, the same reference numerals are given to portions corresponding to those in FIGS. 1 to 6, and overlapping descriptions are omitted as appropriate.

  As shown in FIG. 7, the present embodiment is different from the first embodiment described above in that a synthetic resin conveyance guide member 23 is opposed to the inside of the left and right side walls of the base member 6 via a disk conveyance path. 24, and the roller 25 is installed obliquely from the rear of the central portion of the disc insertion opening 4 toward the one conveyance guide member 24, and the other configuration is basically the same. That is, in the present embodiment, one of the two V-shaped rollers used in the first embodiment is deleted and the other is replaced with one roller 25. Instead, a pair is provided on both the left and right sides of the disk transport path. The transport guide members 23 and 24 are added. Although illustrated in FIG. 7, a guide top and a roller bracket are disposed in front of the drive unit 2, and a disk transport mechanism is configured by the guide top, the roller bracket, and the roller 25. . One end of the roller 25 is rotatably supported by the roller bracket 13 at a position close to the rear of the center of the disk insertion slot 4, and the other side of the roller 25 is positioned relatively away from the disk insertion slot 4. The roller bracket 13 is rotatably supported.

  In the in-vehicle disc player according to the present embodiment, when the disc D is automatically conveyed in the direction of the arrow X2, the same as F1 in FIG. 6 in the direction perpendicular to the axis of the roller 25 from the roller 25 to the disc D. An oblique conveyance force is generated, and the disk D is pressed against the conveyance guide member 23 on the left side of the figure by a component force (F1a in FIG. 6) in a direction parallel to the disk insertion port 4 of the conveyance force. While being guided by the guide member 23, it is automatically conveyed to the play position by a component force (F1b in FIG. 6) in a direction orthogonal to the disc insertion opening 4 of the conveying force. On the other hand, when the disk D is automatically conveyed in the direction of the arrow X1, the disk D is illustrated by the component force in the direction parallel to the disk insertion slot 4 out of the oblique conveyance force generated from the roller 25 to the disk D. Since the disk D is pressed against the right transport guide member 24, the disk D is automatically transported to the eject position by the component of the transport force in the direction perpendicular to the disk insertion port 4 while being guided by the transport guide member 24.

  As described above, in the in-vehicle disc player according to the present embodiment, the pair of transport guide members 23 and 24 opposed to each other through the disc transport path are disposed along the transport direction of the disc D, and one roller 25 is provided. Since the disk is installed obliquely from the vicinity of the center of the disk insertion opening 4 toward the one conveyance guide member 24, the disk D is moved in an oblique direction as the roller 25 rotates, and one of the conveyance guide members 23, 24 is moved. A conveying force is generated to press the disc D, and the disc D can be automatically conveyed between the eject position and the play position using a component of the conveying force in a direction perpendicular to the disc insertion slot 4. it can. As a result, an area in which the disk D can be automatically transported by being sandwiched between the guide top and the roller 25 is widened along the disk transport path direction (arrow X1-X2 direction), and therefore the discharge amount of the disk D protruding from the disk insertion port 4 Even in the case of increasing the disk, it is possible to reliably shift to the clamping operation by using the transport force of the disk D at the play position, and the user can easily grasp the disk D during the ejecting operation and easily from the apparatus main body. It can be taken out. In addition, since both end portions of one roller 25 can be rotatably supported by the roller bracket, the disc transport mechanism including the guide top, the roller bracket, and the roller 25 can be simplified.
