Description of the Related Art Conventionally, as a drive device that reads and reproduces various information recorded on a disc-shaped recording medium such as a CD (Compact Disc) and a DVD (Digital Versatile Disc), and records various information on the disc-shaped recording medium, a disc There is known a configuration in which a state recording medium is detachably attached to perform processing such as reproduction and recording. As such a drive device, a so-called slot-in configuration is known in which a disc-shaped recording medium inserted into an insertion / ejection slot is conveyed by a roller (see, for example, Patent Document 1 and Patent Document 2).

  Patent Document 1 discloses a transfer roller that applies insertion force and ejection force to an optical disk inside a horizontally long slit-shaped disk insertion opening provided on the front surface of a housing, and is opposed to the upper side of the transfer roller. And a disk transport mechanism provided with a guide member. The transfer roller is formed as a drum-shaped roller member having a central portion confined with a material having a relatively large friction coefficient such as synthetic rubber. The guide member serves as a guide for guiding the optical disk to the turntable, and is formed of a material having a small friction coefficient such as a synthetic resin. When the optical disk is inserted between the transfer roller and the guide member, the optical disk sandwiched from above and below is inserted into the disk mounting portion inside the housing or the disk inserted outside the housing according to the rotation direction of the transfer roller. The structure transferred to the mouth is taken. However, in the configuration described in Patent Document 1, there is a risk that foreign matters may be pressed or dragged against the signal recording surface of the optical disk by the transfer roller, and the signal recording surface may be damaged.

  Further, the device described in Patent Document 2 is provided with a pair of drive rollers and a fixed roller that can sandwich the optical disk in the diameter direction, and a drive motor that rotationally drives the drive roller. And while fixing a fixed roller and rotating a drive roller with a drive motor, the structure which transfers an optical disk between a turntable and the disk entrance / exit which inserts / removes an optical disk is taken. However, in the configuration described in Patent Document 2, since the optical disk is conveyed while being held in the diameter direction, the pair of driving rollers and the fixing roller are formed in a drum shape, and the height dimension in the axial direction of the driving roller is Higher and difficult to miniaturize. Furthermore, since the rollers are arranged in pairs in the direction of transport of the optical disk, when the optical disk is held on the turntable and rotated for processing, the rollers are paired in the width direction of the casing that intersects the transport direction without contact. It is necessary to evacuate the rollers that make up, and the construction for evacuation is complicated, making it difficult to reduce the size.

The In the state where the playback disk 11 is held, the projecting portions 372C and 372D with which the periphery of the playback disk 11 abuts are protruded so as to be located on both sides of the pressing piece 373, so that the gap P is an abbreviation of the playback disk 11. It is in a state of expanding toward the center. Further, the reproducing disk 11 is also engaged with the concave groove 384C of the disk engaging portion 384B of the left guide 380. Thereafter, when the reproduction disc 11 is further inserted, the right guide 330 and the left guide 380 are rotated so as to be pushed out by the optical disc 1N in the opposite direction to the facing direction. By this rotation, the switch operation claws 331A2 and 381A2 are moved, and the insertion / extraction detection unit 410 detects that the insertion of the reproduction disc 11 is started by the right guide detection unit 412 and the left guide detection unit 415. When the start of the insertion of the reproduction disk 11 is detected, the device control unit drives the shaft 332 and the like to rotate the rubber ring 363 counterclockwise. As shown in FIG. 27A, the reproduction disk 11 is conveyed into the disk device 100 while being rotated counterclockwise by the rotation of the rubber ring 363 without being urged by the user.

  Further, when the reproduction disk 11 is transported into the disk device 100, the right guide 330 and the left guide 380 are released from the outward bias that is pushed out by the reproduction disk 11, and the guide biasing member is biased. Rotate inward, which is the direction facing each other. While the reproduction disk 11 is conveyed while being held by the pressing piece 373 and the rubber ring 363, the gap P is expanded toward the substantially center of the reproduction disk 11, that is, according to the conveyance of the reproduction disk 11. The conveying means 340 rotates at the tip of the arm member 331 in a state where the head is shaken. When the playback disk 11 is further transported, as shown in FIG. 27B, the right stopper 390 and the left stopper 400 are urged outward by the transported playback disk 11 to rotate. Thereafter, as shown in FIG. 28A, the right stopper 390 and the left stopper 400 correspond to positions where the entire reproducing disk 11 is conveyed into the disk device 100 and the reproducing disk 11 is pivotally supported by the turntable 221. Then, the insertion / ejection detection unit 410 detects that the entire playback disk 11 has been inserted by the right stopper detection unit 413 and the left stopper detection unit 416. Then, when the insertion of the entire reproduction disk 11 is detected, the apparatus control unit stops the rotation of the rubber ring 363 and ends the conveyance. That is, the optical disk 1N is held by the right guide 330, the left guide 380, the right stopper 390, and the left stopper 400 of the disk holding mechanism 320, and is in a state as shown in FIG.

  Thereafter, the apparatus control unit rotates the rotating member 560 from the state shown in FIG. 22 to the state shown in FIG. 21 and FIG. 20 by driving the rotating member control mechanism 550, and the disk holding mechanism 320 is mounted. Move to. In this downward movement process, the locking claw portion of the turntable 221 is moved to a state of gradually retreating from the outer peripheral surface of the shaft support portion 221A, and the turntable is inserted into the disc hole 1NA that opens to the approximate center of the playback disc 11. The shaft support portion 221A of 221 is gradually inserted. Then, when the disk holding mechanism 320 reaches the mounting position, the apparatus control unit drives the retraction control mechanism 420, and as shown in FIG. 28B, the right guide 330, the left guide 380, the right stopper 390, and the left stopper 400 is evacuated. As a result, the reproduction disc 11 is released from the holding by the right guide 330, the left guide 380, the right stopper 390 and the left stopper 400 and is mounted on the turntable 221. After that, the apparatus control unit rotates the rotating member 560 from the state shown in FIG. 20 to the state shown in FIG. 21 and FIG. 22, and inserts the disk holding mechanism 320 as shown in FIG. While moving to the discharge position, the right guide 330, the left guide 380, the right stopper 390 and the left stopper 400 are rotated again to move to the standby position.

  When the apparatus control unit recognizes that the disk holding mechanism 320 shown in FIG. 25C is located at the insertion / ejection position, the apparatus control unit operates the disk processing unit 200 to store information recorded on the reproduction disk 11. Read or record information on the reproduction disk 11.

  In addition, when the replacement disk 12 is inserted by the user, the apparatus control unit performs the above-described FIGS. 26 (A), 26 (B), 27 (A), 27 (B), and 28 (A). In the same manner as in the state up to, the exchange disk 12 is transported inside as shown in FIG. When the replacement disk 12 is transported, as described above, the right guide 330 and the left guide 380 are rotated, so that the apparatus control unit recognizes that the optical disk 1N is newly inserted. Based on this recognition, the apparatus control unit controls the disk processing unit 200 to stop the process when the reproduction disk 11 is being read or recorded. Thereafter, the rotating member 560 is rotated from the state shown in FIG. 22 to the state shown in FIG. 23 and further shown in FIG. 24, and the disk holding mechanism 320 is moved to the temporary fixing position as shown in FIG. . Then, as shown in FIG. 25 (F), the conveyance control unit temporarily fixes the replacement disk 12, and the right guide 330, the left guide 380, the right stopper 390, and the left stopper 400 are again shown in FIG. 28 (B). After retracting to such a retracted position, the disk holding mechanism 320 is moved to the mounting position as shown in FIG. Further, as shown in FIG. 29B, the apparatus control unit releases the retracted states of the right guide 330, the left guide 380, the right stopper 390, and the left stopper 400 under the control of the retract control mechanism 420 and moves toward the standby position. The playback disk 11 is held by rotating. Then, as shown in FIG. 29C, the disc holding mechanism 320 holding the reproduction disc 11 is moved to the insertion / ejection position. Thereafter, a process opposite to the process described above is performed to move the reproduction disk 11 from the state shown in FIG. 29B to the state shown in FIG. That is, the apparatus control unit drives the shaft 332 and the like to rotate the rubber ring 363 clockwise, and discharges the reproduction disk 11 from the disk insertion port 111A so as to be sent out.

  Further, as shown in FIG. 29D, when the apparatus control unit detects that the playback disk 11 has been pulled out and ejected by the user, the right guide 330, the left guide 380, the right stopper 390, and the left stopper 400 are detected. As described above, the disk holding mechanism 320 is temporarily moved to the mounting position, and the right guide 330, the left guide 380, the right stopper 390, and the left stopper 400 are moved inward to be the standby positions again. do. In this case, since the reproduction disk 11 has already been ejected, the reproduction disk 11 cannot be held and is rotated to the standby position, and the apparatus control unit uses a special detection means that the reproduction disk 11 is not present. It can be recognized without. Thereafter, the apparatus control unit again moves the right guide 330, the left guide 380, the right stopper 390, and the left stopper 400 to the retracted position, and moves the disk holding mechanism 320 to the temporary fixing position. Then, as shown in FIG. 29E, the retracted state of the right guide 330, the left guide 380, the right stopper 390, the left stopper 400, and the like is released, and the replacement disk 12 temporarily fixed by the temporary fixing portion 600 is held. . Thereafter, as shown in FIG. 29 (F), the apparatus control unit moves the disk holding mechanism 320 to the mounting position and mounts it on the turntable 221, and moves the disk holding mechanism 320 to the insertion / ejection position to perform an exchange process. , Ie, the standby state shown in FIG. The apparatus control unit recognizes this state, operates the disk processing unit 200, reads the recorded information using the replacement disk 12 as the reproduction disk 11, and records information on the reproduction disk 11. It should be noted that when moving from the state shown in FIG. 29D to the state shown in FIG. 29E, it is not limited to the case where it is once moved to the mounting position and then moved to the temporarily fixed position. 11 may be recognized and moved directly from the insertion / ejection position to the temporary fixing position.

  In addition, when the eject button 111B is operated in the standby state shown in FIG. 25C, as described above, the device control unit drives the retreat control mechanism 420, and as shown in FIG. The guide 330, the left guide 380, the right stopper 390, and the left stopper 400 are retracted. Then, the apparatus control unit moves the disk holding mechanism 320 to the mounting position, and again moves the right guide 330, the left guide 380, the right stopper 390, and the left stopper 400 to the standby position. As a result, the reproduction disk 11 is held by the disk holding mechanism 320 as shown in FIG. Then, the apparatus control unit moves the disk holding mechanism 320 to the insertion / ejection position while holding the reproduction disk 11. Then, the device control unit drives the shaft 332 and the like to rotate the rubber ring 363 clockwise, and discharges the reproduction disk 11 from the disk insertion port 111A so as to be discharged.

[Effects of disk unit]
As described above, in the above-described embodiment, the conveyance is supported by the arm member 331 so as to be rotatable about the central axis substantially orthogonal to the plane, and is moved in the direction in which the retreat control mechanism 420 advances and retreats on the conveyance path. A rubber gear 361 is integrally provided on the one end side in the axial direction on the base 350 and is rotatable about a central axis inclined approximately 5 ° with respect to the orthogonal direction in the plane of the plane in which the optical disk 1N is conveyed. The peripheral edge portion of the optical disk 1N that is supported on the ring 363 and transported on the transport path by the other end surface in the axial direction of the rubber ring 363 while being substantially opposed to the other end surface in the axial direction of the rubber ring 363 is thick. A pressing piece 373 that is held in the vertical direction is provided. Further, the roller driving gear 336 that engages with the gear 361 and applies a rotational driving force that rotates the gear 361 is substantially parallel to the rotating central axis of the transport base 350, that is, substantially orthogonal to the plane in the plane direction. It is pivotally supported on the arm member 331 so as to be rotatable around the central axis. Then, at least one of the gear 361 and the roller drive gear 336 is set to a twist angle that is a maximum value in a range in which an angle between the center axis of the gear 361 and the center axis of the roller drive gear 336 is changed by the rotation of the conveyance base 350. It is formed in an inclined tooth shape that is set as the maximum value of the difference.

  Therefore, a gear 361 that rotates the rubber ring 363 held by the pressing piece 373 and conveyed by rotation, and a roller driving gear 336 that applies a rotational driving force that rotates the rubber ring 363 to the gear 361 are mutually connected. Even if the relation of the center axis of the shaft is inclined, the rotational drive force can be transmitted by being meshed with each other, and for example, the center axis is rotatably supported by a center axis substantially parallel to the roller drive gear 336, and the gear 361 has a rubber It is not necessary to provide a transmission gear or the like whose end face side is engaged in the substantially opposite direction, which is substantially the axial direction, on the opposite side of the ring 363 and whose peripheral surface is engaged with the roller drive gear 336, and the thickness of the conveying means 340 is reduced. In addition, the configuration is simplified, and it is easy to reduce the size, improve the manufacturability, and reduce the cost.

  Then, for example, by forming a bevel tooth shape with a predetermined torsional angle that corresponds to a range of 0 ° to 5 ° of the angle formed by the central axis, the transport base 350 rotates and the center of each other Even if the positional relationship in which the angle between the axes changes in the range of 0 ° to 5 °, the deviation of the inclination of the inclined teeth that mesh with each other is in a range smaller than 0 ° to 5 ° in absolute value. Therefore, a good meshing state with no shakiness is obtained, and even if the transport base 350 rotates according to the position on the transport path of the optical disc 1N, a good transmission of the rotational driving force due to the good meshing state is obtained. Therefore, good conveyance can be achieved with a small configuration.

  In particular, the inclination of the torsion angle in the opposite direction is 2.5 ° which is ½ of the maximum value of 0 ° to 5 ° which is a range fluctuated by the rotation of the conveyance base 350 at the angle formed by each central axis. It is formed in a tooth shape, and the difference between the twist angles is set to 5 °, which is the maximum value of the angle formed by the central axis. For this reason, the difference between the minimum and maximum angles formed by the central angle is shifted by 2.5 ° due to the rotation state of the conveyance base 350 where the torsion angle is most shifted, and the deviation angle is set to be the smallest, and more A good meshing state is obtained.

  In addition, the left guide 380 holds the optical disc 1N in the substantially radial direction and conveys it to one end side of the rotating arm member 331 of the right guide 330, and to the approximate center of the optical disc 1N according to the conveyance of the optical disc 1N to be conveyed. The conveying means 340 is provided so as to be rotatable in a state where the gap portion P is widened toward the surface. For this reason, the optical disk 1N can be moved back and forth in the transport path of the optical disk 1N as compared with the conventional configuration of holding by a pair of rollers in the so-called slot-in method, and the optical disk 1N can be moved during recording / reproduction processing of the optical disk 1N or replacement of the optical disk 1N. Thus, a configuration in which the disk device 100 can be easily reduced in size can be easily obtained by retreating to the front corner portion of the case body 110 that becomes a dead space at the outer peripheral edge. In other words, in order to reduce the size of the disk device 100, the structure of the conveying means 340 that effectively uses the dead space can reduce the thickness of the disk device 100, thereby further reducing the size of the disk device 100. Furthermore, since the configuration in which the optical disk 1N is transported along the plane direction in a state where the optical disk 1N is carried into or out of the case body 110 via the disk insertion opening 111A can use a dead space, the optical disk 1N is exchanged in the case body 110. In particular, it is possible to easily obtain a state in which the transport means 340 moves relative to the optical disc 1N in the thickness direction, which is particularly preferable.

  Then, in order to hold the optical disk 1N in a configuration that effectively uses the dead space to reduce the size of the disk device 100, the gap portion P is directed toward substantially the center of the optical disk 1N being transported. As a configuration that enables rotation to a state where the optical disc 1N expands, projecting portions 372C and 372D project so that the peripheral edge of the optical disc 1N can be brought into contact with the pressing piece 373 constituting the gap portion P in a substantially positioned state. Yes. For this reason, the structure of the small conveyance means 340 which can convey the optical disk 1N satisfactorily by using the dead space effectively with a simple structure can be easily obtained.

  Further, as the pressing piece 373, there is provided an inclined surface 373A that curves so that the narrowest gap dimension of the gap portion P is slightly narrower than the thickness dimension at the periphery of the optical disc 1N. For this reason, in a state where the pressing piece 373 is substantially opposed to the rubber ring 363, a state is obtained in which the gap portion P is expanded toward the transport path and the optical disk 1N to be transported can be gripped by the rubber ring 363. Thus, a configuration in which the optical disk 1N is sent out with the left guide 380 by the rotation of the rubber ring 363 can be easily obtained.

  Further, a pressing piece 373 is provided so as to hold the periphery of the optical disc 1N at a position where the gap dimension of the gap with the upper surface of the rubber ring 363 becomes narrower with respect to the center of the rubber ring 363. For this reason, in order to convey with the end surface of the rotating rubber ring 363, the structure which hold | grips with the end surface of the rubber ring 363 is obtained easily, and it is in the state which substantially opposes the center of the rubber ring 363 for about half circumference. It is only necessary to project, and the size can be reduced more easily.

  In addition, a pressing spring 374 is provided that applies an urging force in a direction in which the end surface of the rubber ring 363 and the pressing piece 373 come close to each other along the direction in which the end surface of the rubber ring 363 and the pressing piece 373 hold the optical disc 1N. ing. For this reason, even if the thickness dimension of the optical disk 1N to be conveyed varies, such as dimensional tolerance, the end face of the rubber ring 363 and the pressing piece 373 can be securely held by the urging force of the pressing spring 374, and the optical disk can be surely 1N can be conveyed. In particular, since it is a simple configuration using the pressing spring 374, a configuration that can securely hold the optical disc 1N can be easily obtained.

  Further, the rubber ring 363 is formed of a soft member. For this reason, even if there is some variation in the thickness dimension of the optical disc 1N, it can be securely held by elastic deformation of the soft member and can be transported satisfactorily without causing any damage to the recording surface of the optical disc 1N. Furthermore, since the gap P is provided in a state where it is widened and the peripheral edge of the optical disk 1N is held and conveyed, inconveniences such as damage to the recording surface or the label surface can be prevented. In addition, the rubber ring 363 side is conveyed as the recording surface side. For this reason, it is only necessary to provide a pressing piece 373 with which the periphery of the optical disc 1N is slidably contacted for conveyance, and it is not necessary to be held by a pair of rotating bodies, and the configuration can be further simplified and rotated. A soft member can be easily provided as a body, and the recording surface can be easily prevented from being damaged.

[Modification of Embodiment]
In addition, this invention is not limited to each embodiment mentioned above, The deformation | transformation shown below is included in the range which can achieve the objective of this invention.

  That is, as described above, the present invention is not limited to the configuration applied to the disk device 100. For example, a disk-shaped form having a hole at a substantially central position, such as a steel plate, and any disk-shaped object containing a disk-shaped object can be attached and detached. The present invention can be used as a holding device that is held by a processing device such as heating or cooling, or can be applied to a configuration that is held by a processing device such as processing a steel plate. Further, the configuration is not limited to being integrated into the disk device 100, and may be a separate body. Further, the disk device is not limited to a structure that does not have a disk changer mechanism for exchanging the optical disk 1N, and is not limited to a structure in which the conveying means 340 is advanced and retracted by the rotation of the arm member 331. Any configuration can be applied, such as a configuration in which it can be arranged and moved forward and backward in the transport path. Further, although the conveying means 340 is provided only on the right guide 330 side, it may be provided on the left guide 380 as well. According to such a configuration, the transport speed of the optical disc 1N is improved, and the optical disc 1N can be transported quickly. Further, it may be provided not on the right guide 330 but on the opposite left guide 380 side. Further, although the left guide 380 is configured to include the arm member 341, it may be configured to be a fixed type that is disposed in the case body 110 along the conveyance direction in a guide rail shape.

  Further, as the disk device 100, when holding the optical disk 1N transported in the plane direction like the tray system or the slot-in system, the shaft support section 611 advances on the transport path of the disk processing section 200 which is a so-called traverse mechanism. When the disk processing unit 200 is moved to a state and transported, the disk processing unit 200 is moved to a state in which the shaft support unit 611 is retracted from the transport path, for example, the disk processing unit 200 is moved by the elevation control mechanism 500. Also good. Even with such a configuration, a configuration in which the dead space is effectively used to advance and retract can be easily obtained, and the disk device 100 can be easily downsized. Furthermore, the present invention can be applied not only to the disk device 100 mounted on the vehicle, but also to a configuration that is mounted on a personal computer, a configuration that is mounted on home appliances such as an audio device and a recording device, and the like.

  The structure for holding the optical disk 1N to be conveyed as the end face of the rubber ring 363 is not limited to the pressing piece 373 projecting from the side where the rubber ring 363 contacts the optical disk 1N during conveyance, and any structure for holding can be applied. Further, the rubber ring 363 may be provided in a state of being inclined without providing the inclined surface 373A. Since the inclined surface 373A is in an inclined state, the peripheral edge portion is in sliding contact with the pressing piece 373 even on the label surface side of the optical disc 1N, and the label surface can be prevented from being damaged with a simple configuration.

  In addition, the torsion angles of the gear 361 and the roller drive gear 336 are formed in a slanted tooth shape in the opposite directions and ½ of the maximum value in the range in which the angle formed by the center axes of each of the gears 361 is rotated. However, it is not limited to ½, and at least one of them is appropriately opposite to the state where the maximum value of the angle formed by the central axis is the maximum value, that is, the state where the difference is 5 ° within the range of 0 ° to 5 °. Set the direction. Further, even if the inclination of the central axis of the gear 361 is 5 ° as described above, for example, when the angle between the central axes, which fluctuates in the rotation range of the conveying means 340, does not reach the maximum value of 5 °, What is necessary is just to set a torsion angle so that it may become the maximum at the maximum value which the center axis which fluctuates in the rotation range makes.

  Furthermore, although the description has been made by pivotally supporting the transport base 350 in a state in which the gap portion P is expanded toward the substantially center of the optical disk 1N being transported, for example, the shapes of the protrusions 372C and 372D are different. The gap portion P may be expanded toward a position shifted from the approximate center of the optical disc 1N. In addition, as a configuration in which the transport unit 340 is rotated in accordance with the transport of the optical disk 1N in order to favorably hold the gap P, any shape that can contact the peripheral edge of the optical disk 1N is not limited to the protrusions 372C and 372D. Applicable. Note that, as described above, the protrusions 372C and 372D that protrude substantially symmetrically on both sides of the gap P can easily provide a structure that can be securely held with a simple structure.

  Further, the configuration is such that the narrowest gap dimension of the gap portion P is not limited to a state in which the gap dimension is always narrower than the thickness dimension of the peripheral edge of the optical disc 1N. And so on. Further, the biasing force is applied in the direction to be held by the pressing spring 374, but the configuration is not limited to the configuration of a coil spring or the like, and any configuration in which the biasing force is applied by a restoring force by elastic deformation can be applied. Moreover, although the structure which makes the restoring force with respect to compression act as urging | biasing force was demonstrated, it is good also as a structure which acts, for example, tensile force as urging | biasing force. Further, a configuration in which the urging force is applied is not provided, and a configuration in which a dimensional tolerance is absorbed by a soft member may be used.

  The rubber ring 363 has a structure in which the entire end surface is a soft member. However, for example, a soft member may be provided at least in a part to be held, such as a soft member provided only at an outer peripheral part holding the peripheral edge of the optical disc 1N.

  In addition, the specific structure and procedure for carrying out the present invention can be appropriately changed to other structures and the like within a range in which the object of the present invention can be achieved.

[Effect of the embodiment]
As described above, the transport base 350 is pivotally supported by the arm member 331 so as to be rotatable about a central axis substantially orthogonal to the plane, and is moved in the direction of moving back and forth on the transport path by the retraction control mechanism 420. A rubber ring 363 is rotatably supported on a central axis that intersects with a plane including a transport path through which the optical disk 1N is transported. A pressing piece 373 is provided that holds the peripheral edge of the optical disc 1N conveyed in the thickness direction between the other end surface in the axial direction of the rubber ring 363 and substantially opposite to the other end surface in the axial direction. Further, a roller driving gear 336 that engages with the gear 361 and applies a rotational driving force that rotates the gear 361 is attached to the arm member 331 so as to be rotatable about a central axis that is substantially parallel to the central axis of rotation of the transport base 350. Pivot. Then, at least one of the gear 361 and the roller drive gear 336 is set to a twist angle that is a maximum value in a range in which an angle between the center axis of the gear 361 and the center axis of the roller drive gear 336 is changed by the rotation of the conveyance base 350. It is formed in an inclined tooth shape that is set as the maximum value of the difference. Therefore, a gear 361 that rotates the rubber ring 363 held by the pressing piece 373 and conveyed by rotation, and a roller driving gear 336 that applies a rotational driving force that rotates the rubber ring 363 to the gear 361 are mutually connected. Even if the relation of the center axis of the shaft is inclined, the rotational drive force can be transmitted by being meshed with each other, and for example, the center axis is rotatably supported by a center axis substantially parallel to the roller drive gear 336, and the gear 361 has a rubber It is not necessary to provide a transmission gear or the like whose end face side is engaged in the substantially opposite direction, which is substantially the axial direction, on the opposite side of the ring 363 and whose peripheral surface is engaged with the roller drive gear 336, and the thickness of the conveying means 340 is reduced. It is possible to simplify the configuration, for example, it is also possible to achieve a good meshing state without shakiness as an inclined tooth shape with a torsion angle inclined in opposite directions. Obtained, it can satisfactorily convey a simple configuration, miniaturization easily achieved.
