Description

  The present invention relates to a recording and / or reproducing apparatus that moves a pickup device over the inner and outer circumferences of a rotating recording medium and records and / or reproduces an information signal on the recording medium, and the recording and / or reproducing apparatus The present invention relates to a loading device that transports a recording medium between a mounting portion of a reproducing apparatus and an insertion / removal port through which the recording medium is inserted and removed.

  In general, optical disks such as CD (Compact Disk) and DVD (Digital Versatile Disk) and magneto-optical disks such as MD (Mini Disk) are widely known as recording media. In order to record and reproduce information signals using these optical discs, various recording and / or reproducing apparatuses are provided. In addition, in order to transport the recording medium between a mounting position where the recording and / or reproducing apparatus is mounted and an insertion / removal position where an insertion / removal port is provided in a casing which is an outer casing of the apparatus main body, Various transport mechanisms (or loading mechanisms) are provided.

  As a transport mechanism (loading mechanism) of the recording and / or reproducing apparatus, there are various types as follows. The first is a type in which a lid and a door provided on a housing are opened upward, and an optical disk is directly mounted on a turntable facing the opening. The second is that an optical disk is placed on a disk tray that is transported horizontally across the inside and outside of the housing, and when the disk tray is pulled into the housing, the optical disk is installed in the housing. This type is automatically attached to the table. The third is a type in which a turntable is integrally provided on the disc tray, and the optical disc is directly mounted on the turntable when the disc tray is pulled out of the casing.

  However, in any of the types 1 to 3 described above, the operator opens / closes the lid and door of the housing, inserts / removes the disc tray, or installs the optical disc on the turntable. Was necessary.

  On the other hand, an insertion / removal port is provided on the front surface of the housing, and the optical disk is automatically drawn into the housing and mounted on the turntable simply by inserting an optical disk from the insertion / removal port. There are slot-in type disk recording and / or playback devices. The slot-in type disk recording and / or reproducing apparatus includes the following types. No. 1 is a type having a roller unit in the vicinity of the insertion / removal opening, in which a conveyance roller for conveying the main surface or outer diameter of the optical disk to be inserted and a support projection are opposed to each other. No. 2 is a type in which an oscillator unit is configured by combining thin oscillators, and the optical disk is moved by the oscillator unit and conveyed to the mounting portion.

  In these slot-in type disk recording and / or reproducing apparatuses, since the latter unit uses a thin sheet metal in the slot-in type disk recording and / or reproducing apparatus using the oscillator unit, the former Compared with the roller unit type slot-in type disk recording and / or reproducing apparatus, the disk recording and / or reproducing apparatus is suitable for thinning. On the other hand, in the latter oscillating unit type slot-in type disk recording and / or reproducing apparatus, it is necessary to operate a plurality of oscillating units in synchronism, which increases the number of parts and the mechanism itself.

  As a conventional roller-type loading mechanism of this type of recording and / or reproducing apparatus, for example, there is one described in Patent Document 1. Patent Document 1 describes a disk-shaped recording medium transport device provided in a digital audio compact disc player. This disk-shaped recording medium conveying apparatus is a "disk-shaped recording medium conveying apparatus having a pair of upper and lower rollers for nipping and conveying an inserted disk-shaped recording medium. Of the pair of rollers, the lower roller is placed on the chassis side. It is attached to a support plate that is rotatably supported, and a motor that rotationally drives the lower roller is attached to the support plate, and is electromagnetically supported on a rotating member that is pivotally supported by the support plate and rotated by the motor. The contact / separation member controlled by the device is provided on the chassis side ”.

  According to the disk-shaped recording medium conveyance device described in Patent Document 1 having such a configuration, “a space saving can be realized if applied to a disk conveyance device of a disk player, and a disc loading movement amount can be freely set. Effects can be obtained.

  Further, as a second example of a conventional roller type loading mechanism, for example, there is one described in Patent Document 2. Japanese Patent Application Laid-Open No. 2004-228561 describes a mechanism that automatically conveys an inserted disc to a turntable, aligns the center thereof, and chucks it in a reproducible state. The loading mechanism of this disc player is described as follows: “The reference surface for setting the disc installation surface of the turntable is set as one side of the drive base on which the pickup is installed, and the turntable is moved from the standby position to cooperate with the disc clamp provided separately. Thus, the disc is chucked at a disc playback position set in parallel at a predetermined interval from the reference plane.

  According to the loading mechanism of a disc player having such a configuration, “the lower surface of the drive base is used as a reference surface, the pickup travel surface is defined, and the turntable surface set by this reference surface is the upper limit, and the turntable is removed from the pickup. Since it moves up and down independently, it is expected that the relative positional relationship between the disk recording surface and the pickup can be maintained very accurately by applying a simple and light moving mechanism.

  However, in any of the above-described conventional roller-type loading devices, since the disk loading operation and unloading (ejecting) operation are performed only with the rollers, each of the insertion / removal position of the insertion / removal opening and the mounting position of the mounting portion is provided. In the position, it was necessary that the roller could be brought into contact with the disk immediately. Therefore, when the loading device is viewed in plan, the roller must be disposed at least at a position overlapping the main surface of the disk mounted on the mounting portion, and is necessarily disposed inside the housing. It was.

  Moreover, in order to prevent the roller from interfering with the disk during recording / reproduction, it is necessary to retract the roller from the main surface of the disk after the disk is mounted on the rotation drive mechanism (turn table). When the disc is ejected, it is necessary to bring the roller into contact with the disc again so that it can be conveyed. As described above, the roller of the loading device needs to be moved to a position by bringing it into contact with the main surface of the disk or returning it to a non-contact state according to the loading state of the disk.

  By the way, the slot-in type disk device is mounted in a drive bay provided in a housing of a host device such as a personal computer (hereinafter referred to as “personal computer”), a game device, or an AV device, and a drive power source is supplied from the host device side. Some are supplied and used together with the host device. Among such host devices, for example, notebook personal computers, thin AV devices, and the like are required to be further reduced in size, weight, and thickness, and accordingly, disks mounted on such host devices are required. The demand for smaller, lighter and thinner devices is also increasing.

  Further, regarding the recording medium, for example, in addition to a standard optical disk having a diameter of 12 cm, a diameter of 8 cm used for a camera-integrated video disk recorder (hereinafter referred to as “camcorder”) or the like, depending on the disc standard, recording capacity, and the like. Various types of discs having different outer diameters are provided. Due to these circumstances, disk devices mounted on personal computers, AV disk recorders and players, and the like are required to be compatible with optical disks of any size.

  Here, as another example of the slot-in type disk device, for example, there is a device described in Patent Document 3. Patent Document 3 describes a so-called slot-in type disk device that can directly insert and eject a disk from the outside. This disk device is “a spindle motor that rotates and drives a disk, a base body that supports the spindle motor, and extends to both sides of the base body to support the base body and reciprocates in the direction of the disk surface. As a result, a pair of slide members that raise and lower the base body in a direction perpendicular to the disk surface, and a first rocker that swings in the direction of the disk surface and draws the center of the disk supplied by the operator to the center position of the spindle motor. And a second oscillating body that oscillates in the direction of the disk surface and discharges the center of the disk from a center position of the spindle motor to a position to be taken out by an operator, and the pair of slide members includes: A first slide member that causes the first rocking body to perform a pull-in operation; and a second slide portion that causes the second rocking body to perform a discharging operation. The spindle motor, the base body, the first slide member, the second slide member, the first rocking body, and the second rocking body are arranged on one side of the disk. It is characterized by

  According to the disk device described in Patent Document 3 having such a configuration, “Because it is a disk conveying means that does not use a roller, the disk device can be thinned. It is possible to reduce the cost and weight of the disk device as a simple configuration that is performed only by the moving body and that also has a slide member that drives both the two rocking bodies and the base body. Can do.

  Such a conventional swing arm type loading device has the following characteristics. Since the loading start position (drawing start position) of the disk is close to the mounting portion, it is necessary for the operator to push more than half of the diameter direction of the disk from the insertion / removal opening. This is because one of the oscillating arms arranged inside the housing is arranged in the vicinity of the insertion / removal port, and the abutting portion of the oscillating arm is located behind the center of the disc to be inserted (operator This is because an operation of pulling the disc in contact with the side close to the side is necessary.

The same applies to the disc ejection completion position, and the disc ejection completion position is where a portion slightly larger than half of the disc diameter direction protrudes from the insertion / removal opening. In this case, it may be possible to extend the discharge completion position to a position equivalent to the roller system by devising the swing arm. However, in the swing arm system, for example, the disk is held with a slight force by a curtain or the like on the front panel. For this reason, the swing arm method cannot obtain a strong holding force like the roller-type transport roller, and there is a possibility that the disc moved to the discharge completion position falls from the disc device.
JP-A-60-136056 JP 2002-175657 A JP 2002-117604 A

  The problem to be solved is that in the conventional swing-type loading device, the disc loading start position and the disc ejection completion position are far from the operator, so the operator pushes the disc to the back of the device during loading. In addition, the operator had to take out the disc from the back of the apparatus during unloading. Therefore, when inserting / removing the disc, the disc cannot be grasped well or the surface on which the information signal is recorded is grasped, which is inconvenient. Further, in the conventional swing arm type disk loading apparatus, it is necessary to insert the disk to the back of the apparatus by the operator's hand at the time of loading, so that the disk may be inclined with respect to the pull-in direction. As a result, if the disc is abutted against a constituent member in the apparatus and damaged, the information signal cannot be recorded or reproduced.

  The loading device of the present application includes a housing provided with an insertion / removal port through which a recording medium is inserted and / or ejected, an insertion / removal position at which the recording medium of the insertion / removal port is inserted and / or ejected, And a transport mechanism for transporting the recording medium between the mounting position of the mounting portion on which the recording medium inserted therein is mounted, and the transport mechanism is a main part of the recording medium inserted into and / or discharged from the insertion / removal port. The axis of rotation extends in a direction substantially parallel to the surface, and the axial length is longer than the diameter of the recording medium. Further, the recording medium is brought into contact with the outer peripheral edge of the main surface by the frictional force in the surface direction. The main feature is that it has a transport member to be moved, and the transport member is arranged outside the outer peripheral edge of the recording medium mounted on the mounting portion.

  Also, the recording and / or reproducing apparatus of the present application is detachably mounted with a housing provided with an insertion / removal port through which the recording medium is inserted and / or ejected, and a recording medium inserted into the housing through the insertion / removal port. A rotation drive mechanism that has a mounting portion and that rotationally drives a recording medium mounted on the mounting portion; A pickup moving mechanism that feeds the pickup device over the inner and outer peripheries of the recording medium, a transport mechanism that transports the recording medium between the insertion / removal position of the insertion / removal opening and the mounting position of the mounting portion, and mounting at the mounting position An attachment / detachment mechanism for attaching / detaching the recording medium to / from the recording unit. The transport mechanism has a rotating shaft extending in a direction substantially parallel to the main surface of the recording medium inserted into and / or discharged from the insertion / removal opening, and has an axial length larger than the diameter of the recording medium. A conveying member that rotationally contacts the outer peripheral edge of the recording medium and moves the recording medium in the surface direction by frictional force, and the conveying member is disposed radially outward from the outer peripheral edge of the recording medium mounted on the mounting portion. It is characterized by.

  According to the loading apparatus and the recording and / or reproducing apparatus of the present application, a conveying member (conveying roller) is provided on the front side of the insertion / removal port, and the recording medium is moved to at least a part of the surface direction by the conveying member. Thus, when the recording medium is inserted, the recording medium is simply inserted to a shallow position of the insertion / removal opening, and then the conveying member conveys the recording medium to the back. Therefore, the operator can perform a smooth insertion / ejection operation of the recording medium and can reduce the thickness of the entire apparatus.

  On the front side of the insertion / removal port, a conveying member is disposed outside the outer peripheral edge of the recording medium attached to the attachment portion. As a result, the loading device and the recording and / or reproducing device that enable the operator to smoothly insert and eject the recording medium and reduce the thickness of the entire device have been realized with a simple structure.

  The first transport mechanism 17 having such a configuration is assembled to the housing 11 as follows, for example. First, the transport roller 40 is assembled to the movable frame 41. In this assembly, the conveying roller 40 is interposed between the pair of bearing pieces 41 a and 41 b of the movable frame 41, and the roller shaft 48 is passed through the bearing holes of both the bearing pieces 41 a and 41 b and the center hole of the conveying roller 40. Then, the driven gear 68 is screwed to one end of the roller shaft 48. Separately, the roller rotation drive unit 44 is assembled to the support frame 43. In this assembly, first, the electric motor 45 is attached to the support frame 43, and the output gear 66 is fixed to the rotating shaft. Next, predetermined gears 67, 71, 72, 73, 74, and 75 are fixed to the six gear shafts 76 a to 76 f provided on the gear support portion 43 b of the support frame 43 by screws 78 and are rotatably supported. To do.

  Next, the second arm piece 49b of the movable frame 41 assembled with the conveying roller 40 is placed in the gap between the arm support portion 43d of the support frame 43 assembled with the roller rotation drive unit 44 and the holding piece 43e. Plug in. At this time, the coil spring 55 is interposed between the receiving portion 43 c of the support frame 43 and the connecting piece 41 c of the movable frame 41. And the axial convex part provided in 43 d of arm support parts is penetrated to the insertion hole 51b provided in the front-end | tip part of the 2nd arm piece 49b, and the stop ring 53b is engaged with the front-end | tip, and it prevents it from coming off. Next, the support frame 43 is screwed to a predetermined position of the lower case 21 using two screws 79. Thereby, the roller rotation drive part 44 which rotationally drives the conveyance roller 40 is arrange | positioned in the space part under the deck part 21b. As a result, even when the first transport mechanism 17 is assembled to the housing 11, the support frame 43 is accommodated in the space formed below the deck portion 21 b, so that the thickness of the apparatus does not increase and the housing does not increase. The thin state of the body 11 can be maintained.

  In this state, the two claw portions 58 a and 58 b provided on the second fixing piece 57 b formed on one side in the longitudinal direction of the upper frame 42 are then connected to the two corners provided on the support frame 43. Hook into the holes 61a and 61b. Next, the first fixing piece 57 a formed on the other side in the longitudinal direction of the upper frame 42 is screwed to the side surface of the housing 11 with a screw 59. Finally, the first arm piece 49a of the movable frame 41 is elastically deformed and spread out, and the insertion hole 51a provided at the tip thereof is a first fixed piece formed on the other side in the longitudinal direction of the upper frame 42.

  In the first transport mechanism 17 having such a configuration, the rotational force of the electric motor 45 is transmitted to the roller shaft 48 through the gear train 46 as follows, and the transport roller 40 is integrated with the roller shaft 48. Driven by rotation. That is, when the electric motor 45 is driven, the rotational force is changed from the output gear 66 to the drive gear 67, the first intermediate gear 71, the second intermediate gear 72, the third intermediate gear 73, the fourth intermediate gear 74 and the fourth gear. 5 is transmitted to the driven gear 68 via the intermediate gear 75. At this time, since the driven gear 68 is integrated with the roller shaft 48 in the rotational direction by a combination of the D-shaped shaft and the D-shaped hole, the rotational force of the electric motor 45 is reliably transmitted to the roller shaft 48 and conveyed. The roller 40 can be reliably rotated. In this case, since the electric motor 45 does not protrude from the support frame 43, the thickness of the disk drive device 10 does not increase, and the disk drive device 10 can be thinned.

  Next, the optical disk transport operation (loading operation) in the first transport mechanism 17 will be described with reference to FIGS. 2, 5C, 6, 13A, B, and 14B. The transport operation of the optical disk 7 in the first transport mechanism 17 is the same regardless of whether it is the large-diameter disk 7L or the small-diameter disk 7S.

  As shown in FIG. 2 and the like, when the operator inserts the optical disk 7 into the insertion / removal port 24, the transport roller 40 is pushed down by the thickness of the optical disk 7 against the biasing force of the coil spring 55 due to the thickness of the optical disk 7. , Move away from the sliding guide 42b. The insertion amount of the optical disk 7 by the operator is detected by a position detection sensor (not shown). When the optical disk 7 is inserted to a predetermined position by the operator's hand, the output of the position detection sensor is turned on, and the detection signal As a result, a control device described later is driven. As a result, the electric motor 45 of the roller rotation drive unit 44 of the first transport mechanism 17 is driven, and the transport roller 40 is rotationally driven in the direction in which the optical disk 7 is pulled into the housing 11 by the driving force. As a result, the optical disc 7 changes from the state shown in FIGS. 2 and 5C to the state shown in FIG. 14B through the states shown in FIGS. 13A and 13B. And it is delivered to the 2nd conveyance mechanism 18 mentioned later.

  Note that the position detection sensor is not limited to a mechanically operated push type detection switch. For example, a light reflection type photo interrupter may be encountered, and other position detection sensors may be used. Is. At this time, when the light reflection type position detection sensor is used, the conveyance roller 40 is a medium thin roll. Therefore, the slide guide 42b is also formed into a medium thin shape so that the inserted optical disk 7 can be conveyed by the conveyance roller. It can be known that the optical disk 7 has been inserted before contacting with 40. As a result, before the operator rotates the transport roller 40 by the pressing force of the optical disc 7, the roller rotation driving unit 44 can be operated to rotate the transport roller 40, so that a smoother loading operation is possible. .

  In the first transport mechanism 17, the transport roller 40 is directly connected to the roller rotation driving unit 44, and the transport roller 40 is always rotationally driven before and after the optical disk 7 is inserted. The transport roller 40 is always urged toward the sliding guide 42b by the coil spring 55, and when the optical disc 7 is inserted, the transport roller 40 moves backward by the thickness of the optical disc 7. When 7 passes, it returns to the original position. In addition, the position where the transport roller 40 is installed is a position outside the outer peripheral edge of the disk 7L having the largest outer diameter among the used optical disks. For this reason, the transport roller 40 can always be rotated during recording and reproduction, and therefore a retraction mechanism for retracting the transport roller downward as in the conventional disk loading device is not required. As a result, according to the embodiment of the present invention, an extra space is not required as long as the conveying roller 40 is not retracted downward or locked at the retracted position, which is advantageous for thinning the apparatus.
