Description

DISC SYSTEM TECHNICAL FIELD The present invention relates to a disk system and particularly to a disk system capable of space saving even in the case where the disk system is configured so that a disk containing position is different from a reproductive position. of disk.

ANTECEDENTS OF THE TECHNIQUE Fig. 106 is a sectional side view showing an essential portion of a general disc system of the related art capable of selectively operating a plurality of discs, and Fig. 107 is a sectional view of the essential portion. In FIGS. 106 and 107, the reference number 1 indicates a feeder reservoir in which the exchange discs are contained, and 2 is a disc rotating portion. The rotation portion 2 of the disk includes a disk rotation motor 3; a disk clamping hub 13 provided on an arrow of the disk rotation motor 3; a disk fixer 4; a roller 6 for disk feed »a disk 8 which is fed by a driving lever 5 provided in the feed magazine 1 and controlled by drive means (not shown)» to the disk rotation portion 2; a driving arrow 9 placed in a box 7 to support the portion 2 of disk rotation; and a tilting cam plate 10 and upper and lower guide plates 11 operated in the direction A in the figures. In this disc system »for removing a plurality of discs B contained in the feeder reservoir 1» the rotating portion 2 of the disc is moved in the direction B in the figures by inter-biting the motor grout 9 »the cam plate 10 of inclination and the guide plates 11 upper and lower »are placed in a desired disc position in the feeder reservoir 1. In this way» according to the disc system of the related art »since the discs contained in the feeder reservoir 1 are perfectly independent of a disk that is rotated in the lateral rotation portion 2 of disk within a flat region »the problem arises that the length» that is »a D-dimension of the disk system becomes longer . To solve the previous problem »for example» the Japanese patent open to the public tJo. Sho 63-200354 has proposed a disk system. Figure 10B is a sectional side view of an essential portion of such a disk system, and Figure 109 is a top sectional view of the essential portion of the disk system. In FIGS. 10 and 109, the reference numeral 19 indicates a feeder reservoir for containing the exchange discs; 21 is a disk rotation motor; 22 is a disc holding hub provided on an axis of the disk rotation motor 21; and 23 is a disk fixer. The reference number 26 indicates a disc roller for feeding a disc 25 fed by a driving lever 24 controlled by driving means (not shown) to a disc rotating portion »and 27 is a driven roller disposed in the position to the roller 26 of disk. The reference numeral 32 indicates a pair of tilting cam plates which are coupled with a plurality of trays 31 in the feeder reservoir 19. When the disc 25 selected by the movement means of the loading reservoir (not shown) moves in the disc plane direction »the pair of inclination cam plates 32 provides an E space greater than at least one plate thickness of the disc on the axis of rotation of the disc 25 with respect to the rotation portion 20 of the disc. At this point »the rotating portion 20 of the disc includes the rotary motor 21 of the disc» the clamping hub 22 of the disc »the clamp 23 of the disc» the driving lever 24 »the disc 25» the disc roller 26 »the drive roller 27"and tilt cam plates 32. The operation of the previous disk system will be described below. To remove any of a plurality of discs 25 contained in the feeder reservoir 19 »the feeder reservoir 19 is moved in the direction F in the figures by the driving means to be placed in the desired disc position in the feeder reservoir 19. The disc 25 it slides along the guide portion of the disk in the magazine magazine 19 by operating the driving lever 24 in the feeder magazine 19 »and the front end of the disk 25 is clamped between the disk roller 26 and the drive roller 27 of the disk rotation portion 20 . Then the disc 25 is brought to the fixator 23 of the disc and the holding mandrel 22 of the disc provided on the lever of the rotation motor 21 of the disc by turning the roller 26 of disk. The fixing position of the disc 25 is verified by disk detecting means (not shown) »of the disc fastener 23» as well as the disc roller 26 and the drive roller 27 move in the direction of the connection to its disk processor 22 by means of the driving means »for fixing the disk 25. At the same time» when the driving roller 27 moves towards the holding hub 22 of the disk »a pair of the inclination plate cams 32 provided in the rotating portion 20 of the disk they move in the feeder tank 19 adjacent to the drive means »to tilt the tray 31 and form a suitable space E as shown in Fig. 108b. The disc system of the related art »configured as described above» requires a feeder deposit box »and consequently» presents problems in that the disks can not be selectively inserted or ejected one by one from the disk rotation portion »Which is large in size. In addition, since the disc system of the related art employs a portable feeder storage case, it is technically difficult to disassemble the frames containing the discs from another which is in the disc system. As a result »to form a space between the desired disc to be reproduced and a disc facing the desired disc» only one open end of the discs can be opened. In other words, "to form a large space between the disks," a space corresponding to the large space must be provided in the system, thus causing the problem that the disk system is large in size. Further »since the disc system of the related art employs a portable feeder storage case» it is very difficult to separate the consoles containing the discs from each other in the disc system while each frame is being tilted. In addition »to ensure a space in the disk system, the problem arises that the disk system is enlarged in size. The present invention has been made to solve the problems described above and an object of the present invention is to provide a disk system capable of miniaturization even in the case where the disk system is configured such that a plurality of disks contain without the need to provide some removable feeder deposit and that is operated each one »that is to say» each disc is inserted »eject and operate» for example »that reproduces selectively. Another object of the present invention is to provide a disk system capable of achieving space saving even in the case where the disk system is configured so that the position containing the disk is different from the disk playing position. Another object of the present invention is to provide a disk system capable of preventing damage to a disk by holding the disk in the insertion or ejection of the disk and moving both roller portions that hold the disk when playing or changing the disk.

DESCRIPTION OF THE INVENTION The present invention provides a disc system including: a portion of its disk holder for attaching to a disk, the disk holder portion being provided in such a way that it is movable substantially in parallel to a transport (or carry) path of the disk. disk in which the disk is transported on a scale from one end to the other end of the disk transport path; and a disk operating portion to rotate the disk »the operating portion of the disk is provided with such that it is movable substantially parallel to the transport path of the disk on a scale from one end to the other end of the transport path of the disk. With this configuration »since the holding portion of the disk and the operating portion of the disk can be moved» the disk R can certainly be maintained and the movement spaces of the disk holding portion and the operating portion of the disk can also be shared. The above makes it possible to make a smaller space in the disk system and therefore miniaturize the entire disk system. The present invention "preferably" further includes a means of motion control for moving »based on an order to transport the disk» the holding portion of the disk and the operating portion of the disk substantially parallel to the transport path of the disk. With this configuration "when the disc is transported" the holding portion of the disc and the operating portion of the disc can be moved to positions substantially parallel to the transport path of the disc. In consecuense, it is certainly possible to hold the disk and therefore improve the reliability of the disk system. The motion control means "preferably" moves the holding portion of the disc and the operating portion of the disc such that the holding portion of the disc and the operating portion of the disc are interlocked with each other. s With this configuration it is possible to hold the disk more reliably and therefore further improve the reliability of the disk system. According to the present invention »preferably» when the disk is transported »it is clamped between the holding portion of the disk and the operating portion of the disk. With this configuration, it is possible to prevent the disk from leaving the operating portion of the disk when the disk is transported »and therefore to improve the reliability of the disk system. The motion control means preferably moves the holding portion of the disk and the operating portion of the disk independently of one another. With this configuration »since the driving portion can be shared for movement» the number of parts can be reduced. Consequently »it is possible to reduce the cost and therefore to realize an economic disk system. The motion control means "preferably" moves to the holding portion of the disk after it moves to the operating portion of the disk. With this configuration »since the operating portion of the disk can be pre-moved to the operating position of the disk before the disk moves to the operating position of the disk» the disk can certainly be operated at a specific position. As a result, it is possible to avoid malfunction and the like and therefore improve the reliability of the disk system.

The motion control means, preferably »allows the disc-holding portion and the operating portion of the disc to hold the disc when the operating portion of the disc operates the disc. With this configuration »since the disc can be clamped between the holding portion of the disc and the operative portion of the disc during the operation of the disc» the disc can certainly be held. As a result »it is possible to prevent the disk from coming off and therefore improve the reliability of the disk system.

The disk system is basically divided into the following three mechanisms: the first mechanism is an insertion / ejection mechanism disk to transport a disk inserted in the disk system to and from a specific position; a second mechanism is a mechanism that contains a disk that includes a plurality of container portions to contain the discs »characterized by reproducing a disc or the like» the container portions are arranged in specific positions with specific spaces to each other; and the third mechanism is a disc holding / reproducing mechanism for holding and reproducing a disc in a specific position. At this point, a basic operation of the disk system will be described below. First »when the disk insertion / ejection mechanism carries a disk in the system, the disk container mechanism is operated» automatically or based on a command »to move a disk containing portion to an adjacent position of the insert mechanism / ejection of the disc and arrange it in the position and to contain the disc in the portion containing the disc. Until now »since the container portion of the disk is adjacent to the disc insertion / ejection mechanism» the disk is contained in the disk containing portion only by operational force of the disc insertion / ejection mechanism. Then »after the disk is contained in the container mechanism of the disk» the containing portion of the disk moves to the original position and waits for the command of an operasional command like the playback command or automatically switches to the next operation. When an operational command such as the playback command is supplied to the disk system, the disk clamping mechanism and the disk-holding mechanism are operated on each other, so that the container-containing portion of the disc-containing mechanism moves "while the disc is held »to a specific operational position» ie »an operational position of the disc, such as a disc playing position» to start the operation of the disc. Then »when disk operation is completed during disk operation» the disk holding / reproducing mechanism and disk-containing mechanism move the disc from the operational pointer of the disk to the disk-containing mechanism while holding the disk, and wait for the command of an operational command such as the playback command, or automatically change to the next operation. Further" when a disk ejection command is supplied to the disk system »the disk container mechanism moves a automatically selected or designated disk containing portion to a pointer adjacent to the disk insertion / ejection mechanism» and the disk insertion / ejection mechanism disk ejects the disk received from the container portion of the disk outside the disk system. In the following, a general configuration of the disk system carrying out the basic operation described above will be described first and then the three mechanisms described above will be described in detail.

Cl. General configuration of the disk system 3 In figure 1 »the reference number 100 indicates a box of a disk disk; 101 is a disk insertion port through which a disk of the disk system is inserted or ejected ie the box 100; and 102 is a disk transport direction along which a disk is carried between the disk insertion port 101 and storages 501 to 504 (which will be described later). The reference number 200 indicates a loading portion for inserting or ejecting a disc in or from the box 100.

The disk loading portion 200 includes a disk upper roller 201 provided in a position facing the labeled side of a disk; and a lower disc roller 202 provided in a position opposite the upper roller 201 of the disc with the disc placed in the middle. The reference number 300 indicates a disc holding portion that functions in the following manner. A disc J "which is placed in the disk system by the disk loading portion 200 and once contained in a disk container mechanism (which will be described later)» is placed in a reproductive position with base in a command that allows reproduction provided from an operation portion (not shown). At that time, the disk fixing portion 300 holds the disk R placed in the reproduction position while pressing the disk R on the upper side to a disk reproduction portion 400 (which will be described later). The disc holding portion 300 includes a fastener 301 for holding a disc; a fastening arm 302 rotatable in the C or D direction to move to a disc reproducing position to contact the fastener 301 with a disc; and a lifting arm 303 for holding a knob portion 3012 of the fastener 301 and raising the fastener 301 upwards. The reference number 400 indicates a disk playing portion for rotating a disk and reading the information stored on the disk. The disk reproduction portion 400 includes a disk turntable 401 provided with a portion on which a disk is mounted; a disk drive motor 402 for rotating a disk mounted on the disk turntable 401; and a receiving portion 403 for reading the information stored on the disk. The reference number 500 indicates a disk container mechanism for containing a disk inserted by the disk roller portion 200. The disk container mechanism 500 is composed of 4 storages 501 to 504 (hereinafter referred to as "first to the actuator 501" second buffer 502. third buffer 503 »and fourth buffer 504) to contain a plurality (four pieces in the mode 1) of disks 501 to 504 are disposed substantially in parallel to a plane of a disc inserted from the insertion port 101. Each from the first buffer 501 to the fourth buffer 504 may contain a disk. Disc in a state in which the axial lines of rotation of the discs are substantially aligned with each other. In the following, each mechanism of the general configuration of the disc system which has been schematically described above will be described in detail.

Disc insertion / ejection mechanism 1 With reference to figures 1 and 2 »the disk insertion / ejection mechanism includes the functions of the disk loading portion 200 as when the disk R is inserted from the insertion port 101, the disc upper roller 201 is rotated in the direction A, ie, counterclockwise, and the lower disc roller 202 is rotated in the direction B, ie »clockwise» to contain the disk R in a specific buffer adjacent to the roll portion 200 of the disk, for example, in the first storage 501. Although in the description. above »the upper disc roller 201 and the lower disc roller 202 are rotated as shown in Figs. 1 and 2» can clearly be operated so that only one roller is rotated and the other roller is brought into contact with a plane of the disk R »that is to say» that does not turn. Fig. 2 is a view illustrating a state in which the upper disc roller 201 and the lower disc roller 202 of the disc system shown in Fig. 1 hold a disc in the middle; and Figure 3 is a view illustrating a state in which the upper disk roller 201 and the roller The lower disk of the disk system shown in Figure 1 releases a disk. The disc insertion / ejection mechanism will be described with reference to Figures 1 and 3. Figure 2 shows a positional relationship between the upper disc roller 201 and the lower disc roller 202 when transporting a disc. At this point »when Di is a space between both rollers» the value DI when holding a disc R corresponds to the thickness (1.2 mm) of the disc. With respect to the actual positional relationship with the disk R »the holding state of the disk R is shown in figure 4. and the release state of the disk R is shown in figure 5. Next» a configuration will be described in detail of a mechanism of the disc operating roller portion 2O0 »and the operation of the upper disc roller 201 and the lower disc roller 202 with reference to Fig. 6a to Fig. 9a. Figures 6a to 6d are front views of essential portions. each one showing a configuration and an operational state of a portion of the front surface of the portion 200 disc roller; Figures 7a to 7d are top views of essential portions, showing a configuration and an operational status of an upper surface of the disk roller portion 200; Figs Ba to 8d are side views of the upper disk roller 201 showing a configuration and an operational state of a side surface of the upper disk roller 201; and Figures 9a to 9d are side views of the lower disc roller 202 showing a configuration and an operational state of a side surface of the lower disc roller 202. In addition »figures 8a and Bd and figures 9a to 9d show the left lateral surfaces of the upper and lower disc rollers 201 and 202 in the mode 1"respectively. Each of the figures 6a. 7a »Ba and 9a shows a state in which the R disk is not inserted; One of the figures 6b »7b» Bb and 9b shows a state in which the disk R moves to be inserted and transported, that is to say »the disk R is clamped; each of the figures 6c »7c, 8c, and 9c show a state which is in the course of extending a space between the upper disk roller 201 and the lower disk roller portion 202 to the maximum» in which the space is extended to place the disk R in the space to move the disk R to a reproduction position; and each of the figures - 6b »7b» Bb and 9b shows a state in which the disk R is placed and reproduced in the space extended to the maximum. That is, such figures show the procedure of the state in which the space between both rollers is minimized to the state in which the space is increased to the maximum of the procedure of the insertion of the disk R to reproduce the disk R in the order of states shown in Figures 6a, 7a »Sa and 9a > Figures 6b »7b» Sb and 9b > Figures 6c »7c» 8c and 9c > figures 6d, 7d, 8d and 9d. The reference numeral 203 indicates a cam plate open to the roller for adjusting a magnitude of a gap between the upper disk roller 201 and the lower disk roller 202. The cam plate 203 open to the roller is composed of a main body 2031 and a cam portion 2032. At this point »the main body 2031 of the cam plate 203 open to the roller has a sliding hole 20311 at one end at the end. side of upper disk roller 201 or side of lower disk roller 202 »and a sliding hole 20312 at the other end. Sliding hole 20311 allows a sliding arrow composed of a base pin (not shown) provided in box 100 to slide therefrom in the direction A or B. Sliding hole 20312 allows a pin 2092 of a link portion 209 (both will be described later) slide therein in the direction C or D. The cam portion 2032 of the cam plate 203 of The roller aperture has a slide hole 20321 for tilt and a tilt portion 20322. The slide hole 20321 allows a pin 2041 provided in a portion of a roller upper arm 204 (both will be described later) to slide in the same. The tilt portion 20322 allows a pin 2022 formed at an anterior end of the lower disc roller 202 to contact a portion of a peripheral edge portion of the cam portion 2032. The reference number 204 is the upper roller arm for holding one end 2011 of the upper disk roller 201. The upper roller arm 204 has the slide of pin 2041 in the sliding hole 20321 of the cam portion 2032 of the cam plate 203 open to the roller »and also has an arrow that fastens the hole 2042 in which the cam engages. base pin (not shown) provided in the case 100. In this case, the open end 2011 of the upper disk roller 201 is formed separately from the pin 2041; however, the pin 2041 can replace the end 2011. The reference numeral 205 indicates a lower roll arm having at its end a lower roller holding portion 2051 and at the other end a holding hole arrow 2052. The roller The lower portion holding portion 2051 holds part of an extension portion 2022 having an arrow portion formed at an anterior end of the lower disk roller 202. In the arrow that attaches to the hole 2052, the base pin Cno shown) is provided in the box 100. The reference number 206 indicates an open link having at one end a pin 2061 coupled in the sliding hole 20312, a hole 2062 of arrow in which the base pin (not shown) provided in the box 100 »and in a peripheral edge of a part of another end engages a sliding contact portion 2063 with which it is brought into contact sliding guide 304 (which will be described later). Next, the operation of the disc insertion / ejection mechanism described above will be described.

First of all »as shown in figures 6a, 7a »8a and 9a» when the disc R is not inserted »the sliding guide 304 is positioned on the side of the insertion port 101, that is, on the side B» and the pin 2061 of the open link 206 is positioned on the side D. So far "since the pin 2041 of the upper roller arm 204 is positioned at the left end in the sliding hole 20321 as shown in figure Ba, the position of the upper disk roller 201 is not changed as the position of the upper roller arm 204 is also not changed. The extension portion 2022 of the lower disk roller 202 held by the holding portion 2051 of the lower roller, is usually deflected on the side of the upper disk roller 201 by an elastic member (not shown) because the position of the cam plate 203 open to the roller is not changed. As a result, the extension portion 2022 is brought into contact with the tilt portion 20322 and a position closer to the upper disk roller. That is, the lower disk roller 202 is located in such a position. In this case, the closest space between the upper disc roller 201 and the lower disc arm 202 is positioned to be slightly thinner (eg, 0.5 mm) than the general groeor (eg, 1.2 m) of the die R for To absorb a variation in the thickness of the discs and to ensure a sufficient disc holding pressure to prevent a disc from moving out of the space between the rollers. Next, in the case where the disk R is inserted from the insertion port 101 in the operational state described above, as shown by the operational states in figures 6fo »7ta» 8b and 9b, since the closest space between the upper disc roller 201 and the lower disc roller 202 is placed to be thinner than the disc thickness as described above »the space opens to a value corresponding to the thickness of the disc as the disc is pulled by the disc rotation of the rollers or similar. Other operations are similar to those described with reference to Figures 6a, 7a, 8a and 9a »and therefore, the explanation thereof is omitted. The disk R »which is inserted by means of the operations shown in figures 6b, 7b» 8b and 9b and which is contained in a buffer »is operated as shown by the operating states and figures 6c 7c» Se and 9c when a command for reproducing the disk R is supplied by the operation portion (not shown). Figures 6b »7b» 8b and 9b each show the state in the course of opening of the rollers when the disk production portion 400 moves to the playing position of the disc, particularly a state which is in the course of of movement in the direction A of the sliding guide 304 connected to move the playing portion 400 of the disc. The slide guide 304 has contact portions 3041 and 3042 to contact the contact portion 2063 provided on the open link 206. As shown in Fig. 7c »since the link portion 206 is rotated in the direction C around the arrow (not shown) engaged in the arrow holding hole 2062 along the movement of the slide 304 in the direction A »the pin 2061 of the link portion 206 slides in the sliding hole 20312 of the cam plate 203 open to the roller, so that it is rotated in the direction C. In addition, since the plate cam 203 open to the roller moves only in the direction A or B »of the rotational force of the opening link 206 in the direction C» only one component of movement in the direction A is transmitted to the cam plate 203 open to the roller to move the cam plate 203 of the roller. In addition »as described above» since the plate cam 203 open to the roller moves in the direction A »ie, moves in the direction E as shown in figure 8c »the upper roller arm 204» that is to say »the upper roller 201 of the disk held by the upper roller arm 204, moves in the direction G because the pin 2041 slides inside the slide hole 20321 of the cam plate 203 open to the roller in the direction F and the slide hole 20321 moving in the direction F moves the upper roller arm 204 in the S direction. as described above »since the cam plate 203 open to the roller moves in the direction A» ie »moves in the direction I as shown in figure 9c, the lower roller arm 205 is pressed towards the portion of the portion 2022 of the extension of the lower roller 201 of the disc in the direction K »that is, rotated in the direction K around the arrow (not shown) engaged in the arrow-holding hole 2052» and consequently ia, the lower roller arm 205 is rotated in the direction K along the tilt portion 20322 of the cam plate 203 open to the roller and therefore the lower disk roller 202 clamped by the roller arm 205 The lower one moves in the K direction. Accordingly, as shown in Figure 6c »the space can be set to a value d3 according to the operation of the sliding guide 304. Finally, when the sliding guide 304 is moved of the operational states shown in Figures 6c, 7c »Se and 9c, in the direction of the A shown in Figure 7c, the operational states of the disk R on the reproduction of the disk R become those shown in Figures 6d , 7d »Sd and 9d. Since the slide guide 304 further moves in the direction A as shown in figure 7d »the opening link 206 is further rotated in the direction C of the state shown in figure 7c to thus move the plate further of cam 203 open to the roller in the direction A. Moreover, during the movement only of the slide 304 in the direction A in a state in which the contact portion 2063 of the slide guide of the opening link 206 is located parallel to the contact portion of the slide guide 304 as shown in the figures »the aperture link 206 no longer moves in the direction C» and even if the aperture link 206 is applied with a force to return the opening link 206 in the direction of the sliding guide 304 is not applied with a force to return the slide guide 304 in the direction B. Accordingly »the roller opening plate 203 Hitherto, as shown in Figure Sd, the pin 2041 of the upper roller arm 204 slides in the sliding hole 20321 of the cam plate 203 open to the roller until a position close to the terminal on the F side, and the upper disc roller 201 moves further in the G direction and is maintained in that position. Further, since the slide 304 further moves in the direction A as shown in Fig. 7d, the tilt portion 20322 of the cam plate 203 open to the roller presses and moves the extension portion 2022 of the bottom roller 202. from disk in the K direction to the terminal portion in the J direction as shown in Fig. 9d »so that the lower disk roller 202 moves further in the K direction and is maintained in that position. The disc insertion / ejection mechanism having the above configuration can perform a series of operations shown in figures 6a to 6d. It is assumed that a space between the disc upper roller 201 and the lower disc roller 202 on a non-insertion of a disc as shown in Fig. 6a is taken as di. In this case »when a disk having a thickness d2 is inserted as shown in figure 6h? the thickness d2 of the disk becomes the space. Next »since the cam plate 203 open to the roller moves in the conveying direction of the disk R to prepare the disk reproduction as shown in figure 6c» the upper disk roller 201 starts to move upwards and the lower disk roller 202 starts moving down to enlarge the space. The space in such a state is taken as d3. When the disc starts to play from the playback readiness state of the disc shown in FIG. 6c, the space is further extended as shown in FIG. 6d. The space in such a state is taken as d4. In summary, the change in the state space shown in Fig. 6a to the state shown in Fig. 6d is expressed by a ratio of di <.; d2 < d3 < d4. In the case of stopping the reproduction of the disk R and the ejection of the disk R, that is, in the case of developing operations contrary to those described above, the disk insertion / ejection mechanism is operated in the order of the states shown in Figures 6d, 7d, 8d and 9d - > Figures 6c, 7c »Se and 9c - > Figures 6b »7b» Sb and 9b - > Figures 6a, 7a »Ba and 9a.

The reference number 304 indicates the sliding guide. One end 3041 of the slide 304 is connected to the base portion 306 (which will be described later) so that the slide 304 moves in the direction A or B. A pin 3042 is provided at the other end. of the slide guide 304 »and slidably inserted in a slider hole 3053 (which will be described later) of the link portion 305. The reference number 305 indicates the link portion that includes the pin 3051 slidably inserted in the sliding hole 3023 of the fixing arm 302 and in the sliding hole 3035 of the lifting arm 303; an arrow fastening hole 3052 for allowing the link portion 305 to be rotated about it with respect to the base portion 306 (which will be described later); and the slide hole 3053 in which the pin 3042 provided in the slide guide 304 is slidably inserted. The reference numeral 306 indicates the base portion provided in the vicinity of the disk roll portion 200 such that it is approximately parallel to the buffer 501 in a state that does not contain a disk. The base portion 306 includes the arrow 3061 inserted in the arrow slide hole 3021 of the clip 302 and the slide hole 3035 of the lift arm 303; has a contact portion 3062 that contacts the end 3041 of the slide 304 to move the slide 304. The reference number 307 indicates the deviation portion formed of a spring. One end of the diverting portion 307 is connected to the holding arm 302 »and the other end of the diverting portion 307 is connected to the lifting arm 303.

Next, the disk fixing operation 300 will be described with reference to Figures 10a to 16c. Figures 10a and 10b and Figures Ia and 11b are views showing a state in which a command allowing reproduction is not supplied from the operation portion; Figures 12a and 12b are views showing a state in which a command allowing reproduction is supplied from the operating portion so that the disk mounting portion 400 starts to move in the direction A and the holding portion 300 of disc starts to move in the direction A along the movement of the disk mounting portion 400; Figures 13a and 13b are views showing a state in which the disc-holding portion 300 moves from the state shown in Figures 12a and 12b to the vicinity of the playing position of a disc; FIGS. 14a and 14b are views showing a state in which the disk holding portion 300 contacts the disk R; and Figures 15a and 15b are views showing a state in which the disc can be reproduced. Fig. 10a is a top view showing a configuration, and Fig. 10b is a front view of Fig. 10a; and the figure is a side view of the configuration shown in Figures 10a and 10b, and Figure 11b is a view showing an essential portion shown in Figures 10a and 10b. Figures 12a. 13a »14a and 15a are top views showing an operational state; and Figures 12b »13b, 14b and 15b are side views of Figures 12a» 13a »14a and 15a» respectively. Figures 16a to 16c are views showing operational states of an essential portion of the disk fixing portion 300, wherein Figure 16a shows a state in which a disk is not mounted; Figure 16b shows a state in which the disk fixing portion 300 is brought into contact with a disk; and Figure 16c shows a state in which the disk is held between the disk fixing portion 300 and the disk mounting portion 400. First, in a state in which a reproducible command is not supplied from the operation portion (not shown), the disk playback portion 400 (the operation of the same will be described later) does not move, so that the movable holding arm 302 does not move through the slide guide 304 and the link portion 305 with base in the movement of the disk reproduction portion 400. As a result, the state shown in Figures 10a and 10b and Figures 1a and 11b are maintained. Secondly »when a command is provided that allows reproduction from the operating portion» the disc reproducing portion starts to move in the direction »A» and the sliding guide 304 connected to the part of the mounting portion of disk also moves in the direction A (which will be described in detail later). Heretofore, the pin 3042 provided at one end of the slide 304 similarly moves in the direction A in the slide hole 3053 of the link portion 305. As a result, the link portion 305 is rotated in the direction B around the arrow portion 3052 of the link portion 305, so that the support arm 302 and the lift arm 303 are rotated in the direction C around the arrow portion 3061 through the pin 3051 of the link portion 305. After the operation shown in figures 12a and 12b, the buffer 5? Containing the disk R moves in the direction D as shown in FIGS. 13a and 13b, and the buffer 503 waits in the reproduction position of the disk R. In addition, a configuration and an operation of the storage will be described in detail later. Next, as shown in Figs. 14a and 14b, the disk reproduction portion 400 moves again in the direction A and the displacement guide 304 moves to the lateral terminal portion A of the contact portion 3062 formed in the base portion 306 along the movement of the disk reproduction portion 400. As a result, the clamping arm 302 and the lifting arm 303 are disposed in the reproducing position of the disk R in association with the above-described operation of the sliding guide 304 .. Then »as shown in FIGS. 14a and 14b» the hook portion 3031 of lifting arm 303 is separated from knob portion 3012 held by fastening arm 302 »and contact portion 3011 of fastener 301 is brought into contact with the disk surface» to thereby hold the disk in cooperation with the turntable 401 of the disk reproduction portion 400 that supports the back surface of the disk. Further »after completing the operation shown in Figures 14a and 14b, in order to reproduce the disk R» the buffer 501 moves in the direction A to the original position as shown in figures 15a and 15b, to reproduce in this way the disk R. At this point, the state in which the disk R between the holder 301 and the turntable 401 of the disk reproduction portion 400 is retained will be briefly described with reference to FIGS. 16a and 16c. Firstly, in the case where the disk R is not arranged in the reproduction position as shown in figure 16a, the clamping arm 302 moves towards the reproduction position of the disk R and also pulls in the direction E by lifting arm 303 to allow the disk R to be easily inserted into a space di between the fastener 301 and the turntable 401. Next when the arm its driver 302 is disposed in the reproducing position of the disk R and the disk R is also disposed in the reproducing position as shown in Fig. 16b »the lifting arm 303 moves in the direction F to release the knob portion 3012 of the fastener 301» so that the contact portion 3011 of the diverted fastener 301 in the G direction it comes into contact with the surface of the disk R. In such a state »the space (d2) becomes smaller than the space shown in figure 16a. Further »since a force of attraction is generated between the surface 30111 for magnetizing» which is provided in the contact portion 3011 of the fastener 301 »and a magnet 40111 provided in a disk mounting portion 4011 of the turntable 401 as shown in figure 16c »the fastener 301 is attracted to the turntable 401» to thereby hold the disc R. In this state »the space (d3 >; is almost equal to the thickness D of the disk R (d3 = D). Further »in the case where the disk reproduction is completed and the disk R is contained in the disk containing the mechanism 4O0» the disk fixing portion 300 is operated in accordance with operations contrary to those described above »ie »The order of the states shown in Figures 15a and 15b - > Figures 14a and 14b - > Figures 13a and 13b - > Figures 12a and 12b > Figures 10a »10b, lia and 11b.

The turntable 401 includes a disc mounting portion 4011 and a projection portion 4012 that are inserted into a central hole in a disc to hold the disc. The magnet 40111 is provided in the disk mounting portion 4011. The reference numeral 402 indicates an optical pickup driver portion for moving an optical pickup portion 403 in the direction A to read the information recorded on a disc; 404 is an optical pickup guide portion for guiding the optical picker portion 403 in the A direction; and 405 is a rotatable feed screw of optical pickup in the direction C or D on the basis of a pulerating force i of the optical pickup driver portion 402. The optical sensor portion 403 includes a sensor 4031 for emitting a light source to a disk and reading the information recorded on the disk; the support portions 4032 and 4033 for supporting the optical sensor guide portion 404 in the A or Bi direction and a screw portion 4034 for screwing with a slotted portion of the optical sensor feeder screw portion 405. When the optical pickup feed screw portion 405 is rotated in the direction C or D on the basis of a rotational force of the optical pickup driver portion 402, the screw portion 4034 converts the rotational force of the portion 405 of optical pickup feed screw moving in the direction A or B »to thereby move the optical picker portion 403 in the direction A or B. Next, a configuration of an operating mechanism for operating the Disc portion 400 of disc described above in the disc system with reference to FIGS. 18a and 18b. Figures 18a and 13b are views showing a configuration of a movement mechanism portion 450 for moving the disk reproduction portion 400 in the A or B direction. A state in which the R disk contains this content is shown in talee figures. In the storage 501. In addition »the figure IBa is a top view and the figure 18b is a front view in section. In Figures IBa and 18b »the reference number 450 indicates the movement mechanism portion for moving the disk reproduction portion 400 shown in Figures 17a and 17b.

In addition, the slide guide 304 is connected to the slide guide 456 to integrate with each other. The functions of the above components will be described in detail below. First, the reference number 451 indicates that the base portion that is fastened to the base portion 306 and is connected to the disk reproduction portion 400 to support it, and which is also movable in the E or F direction.; 452 is the base driving portion for moving the slide 456 (which will be described later) in the E or F direction; 453 is the motor for moving the disk roller portion 200, the disk fixing portion 300 and the disk reproduction portion 400; and 454 is the steering portion for transmitting the rotational force of the motor 453 to the slide 456 which will be described later). The reference numeral 455 indicates the plate guide which is fixed on the bale 451 and which has a groove for guiding the slide 456 and the disk reproduction portion 400.; and 456 is the sliding guide screwed with the steering portion 454 and moving in the E or F direction along with a turn of the steering portion 454. The sliding guide 456 above is part of the sliding guide 456 slidably mounted on the plate guide 455 and the base 451. The reference number 457 indicates the first link portion having at one end a pin 4571 slidably inserted in a sliding hole 4562 provided in part of the slide 456 and also having at the other end an arrow portion 4572 rotatably fixed in the base portion 451; 458 is the second link portion having at one end an arrow portion 4581 for rotatably supporting the slide 456 and also having at the other end a pin 45B2 slidably inserted in a slide hole 4511. formed in part of the portion of base 451; and 459 is the arrow portion for connecting the first link portion 457 on the second link portion 458 and rotatably supporting the first link portion 457 and the second link portion 458. Next, the operation of the mechanism portion 450 of movement will be described with reference to figures 18a to 28c. As previously described, FIGS. 18a and 18b show the state in which a command that allows disk reproduction is not supplied from the operation portion and therefore disk portion 400 is not operated. As shown in Figures 18a and 18b, the slide guide 456, the first link portion 457, and the second link portion 458 are disposed at positions closer to the insertion port 101. At this point, Figure 19 shows a state in which the disk reduction portion 400 shown in Figures 17a and 17b is mounted in the operating mechanism shown in Figures 18a and IBb. In such a state, the disk reproduction portion 400 is not superimposed on the disk R contained in the SOI buffer. Figures 20a and 20b are views showing a left side surface of the mechanism shown in Figures IBa and 18b and Figure 19, wherein Figure 20a is a side view and Figure 20b is an illustrative view of Figure 20a. Next, when a command allowing the disc to be reproduced is supplied to the disc system, the motor 453 is driven and the driving force is transmitted to the slide 456 through the direction to move the slide 456 in the direction F »so that the connected disk reproduction portion 400 of the slide 456 also moves in the direction F. Such a state is shown in figure 21. In such a state» the mechanism 200 of the disk roller is opened up and down by the mechanism described above as shown in figure 12d »to allow the entry of the disk R. Moreover» the store 501 moves in the direction E and the disk R moves from a position Rl to a position R2 of reproduction. Figure 22 shows a state in which the portion 400 of disc play is mounted in the state shown in Fig. 21. The movement of the disc playing portion 400 further advances to the playing position of the disc, and when the movement of the disc is completed, the disc is held between the disk fixing portion 300 and the reproduction portion 440, to thereby initiate the reproduction of the disk R. Such a state is shown in Figures 23a and 23b. Furthermore, FIG. 24 shows a state in which the disk reproduction portion 400 is mounted in the state shown in FIGS. 23 a and 23 b. In Figs. 23a and 23b and Fig. 24, the motor 453 is further urged to move the slide 456 through the engaging portion 454 in the direction E. In this manner, the slide 456 moves further in the direction E »and in this way the pin 4571 of the first link portion 457 slides further into the sliding hole 4562 of the slide 456 in the direction G; however, when an end portion of the sliding hole 4562 is reached on the side of the slide 304 »the pin 4571 is prevented from moving further in the direction G. Like the pin 4571 of the first link portion 457 »the pin 4582 of the second link portion 458 further slides the sliding hole 4511 of the base portion 451 in the direction G: however» when an end portion of the sliding hole 4511 is reached on the side of the Sliding guide 304 prevents the pin 4582 from moving further in the direction G. As a result, movement of the first link portion 457 and the second link portion 458, and the portions in which the stop is stopped, is prevented. The movement of the link portions 457 and 458 are established at reproducing positions of the disk R. In this way, the link portions 457 and 458 can be easily established at the playback positions of the e disk. Figures 25a through 28s are sectional views of the right and left sides of the essential portions shown in the above operations. Figures 25a to 25c are left side views in section "wherein Figure 25a shows a state in which the state shown in Figures 10a and 10b are assembled with the state shown in Figure 19; Figure 25b illustrates a state in which the state shown in Figures 12a and 12b is assembled with the state shown in Figure 22; and Figure 25c shows a state in which the state shown in Figures 13a and 13b is assembled with the state shown in Figure 24.

C4 Disk Container Mechanism The disc container mechanism will now be described. The disk container mechanism 500 basically includes the web portions 501 through 504; a portion 510 of the drive mechanism for driving the movement of the storages 501 to 504; and a movement mechanism portion 520 to give a specific movement to each of the storages 501 to 504 at each specific stage on the driving force bases of the drive portion portion 510. In addition, the means of movement of a storage device ee consist of the drive portion 510 and the movement mechanism portion 520. First, a configuration of the first storage portion will be described with reference to FIGS. 29 and 30. FIG. 29 is a sectional view of an essential portion of the disk containing a mechanism 500"and FIG. 30 is a view. which shows a state in which the components of the essential portion shown in Figure 29 are assembled. In the following description of the storage portion as the essential portion "the storage portion is represented by the first storage 501 positioned in the highest stage. In Figures 29 and 30 »the first buffer 501 includes a containment portion 5011 for containing a disk; a stop 5012 to prevent a disk contained in the containment portion 5011 from moving in the direction A; a secure portion 5013 for securing a peripheral edge of a disc contained in the containment portion 5011, thereby preventing the disc from moving in the direction B; a projection portion 5014 formed in the kneader 501 in such a way that it fits into a coupling hole 50131 formed in the lock portion 5013 and rotates around the coupling hole 50131; a branch portion 5015 coupled with a coupling portion 50134 of the insurance portion 5013 to commonly derive the insurance portion 5013 in the direction C; and a holding portion 5016 fitted in an adjustment hole 5017 formed in the buffer 501 to maintain the bypass portion 5015. Further »a slide rail portion 501B is formed in part from a portion of the peripheral edge of the buffer 501, and as shown in figure 31 »the slide rail portion 5018 is slidably inserted in a rail portion 5019.

Next, the operation of the first buffer 501 described above with reference to FIGS. 31 and 32 will be described. At this point, FIG. 31 is a view showing a state in which the first buffer 501 contains the disk R "that is, in FIG. a state in which the disk R is inserted and contained in the first buffer 501 and the first buffer 501 is moved to a specific position; and Fig. 32 shows a state in which the first store 501 moves in the direction B, ie, in a state in which the disk R is contained or ejected from the containment portion 5011 of the first store 501. As shown in Figs. shown in figure 31 »when the store 501 containing the disk R is located at a specific position» if an external factor to move the disk R in the direction B and expel it from the containment position is applied to the disk R, a force revolving in direction E is given from disk R to insurance portion 5013; however, because the contact rail portion 50133 provided in the insurance portion 5013 comes into contact with the rail portion 5019, the rotation of the insurance portion 5013 is prevented. As a result, the insurance portion 5013 maintains disk R, and prevents movement of the disk R. Next »when the disk R is transported or reproduced» that is, the disk is sent to the disk loading portion 100 or sent to the mounting portion 400 of disk to reproduce the disk R, the prevention of the movement of the disk R shown in figure 31 should be allowed. In this case as shown in figure 32. by moving the first buffer 501 in the direction B »the rail portion 5019 is separated from the contact rail portion 50133 provided in the safety portion 5013 »to allow the prevention of rotation of the safety portion 5013 in the direction E» thus allowing the disc R to be maintained by the portion 5013.

Fig. 33 is a view showing a state in which the disk R is inserted and contained in the first store 501 or ejected from the first store 501; Fig. 34 is a view showing a state in which the disk R contained in the first buffer 501 moves to a playback position and the disk mounting portion 400 moves to the playback position; and Figure 35 is a view showing a state in which the first store 501 returns to the containment position and the disk R is reproduced. First, as shown in Figure 33, when the disk R is inserted from the port of insertion (not shown), the sliding portion of the rail 5018 slides in the direction A with respect to the rail portion 5019 supported by the housing 100 whereby the first storage 501 is projected in direction A. Until now the The safety portion 5013 is rotatable in direction B because the rail portion 5019 does not contact the contact rail portion 50133. Accordingly, the disk R rotates the lock portion 5013 in the direction B against a bypass force of the bypass portion 5015 by the rotary force of the disc upper roller 201 »to thereby be contained gently in the containment portion 5011 of the first storage 501. Next» as e shows in Fig. 34 »when an order allowing the reproduction of the disk R is sent from the operating portion (not shown)» the mounting disk portion 400 moves in the direction B and is placed in a position 400 B shown by a dotted line.

In the following "three basic operations of the total disc system shown in the embodiment 1 described above will be dessibed with reference to FIGS. 67a to 95b. The three basic operations are: (1) an operation in which the disks are contained in all storage units from a non-containing disk state and a specific disk is played; (2) an operation in which during the playback of a specific disc »such playback is interrupted within the playback of another disc; and (3) an operation in which the reproduction of a specific disc stops and the specific disc is ejected. Referring in the first place to FIGS. 67 a to 82 b, operation (1) »that is to say» the operative stage of the entire disk system will be described from a state in which the dies are held in the first web 501 to the buffer 504 in this order from the state without disks contained in the seventh of dieso to a state in which a disso R2 contained in the second buffer is reproduced. Figures 67a and 67b are views showing a state in which no disk is contained in the disk system; Figures 68a and 68b are views showing a state in which an order is given from the operation portion (not shown) or the like that allows a disk RI to be inserted into the first buffer 501 and the first buffer is moved forward of the port of insertion; Figures 69a and 69b are views showing a state in which the disk Rl is inserted from the inesion port 101; Figures 70a and 70b are views showing a state in which the disk Rl is contained in the disk containment portion of the first buffer 501; and Figures 7la and 7lb are views showing a state in which the first store 501 containing the disk Rl is moved to the original position "ie the position shown in Figures 67a and 67b.

Figures 77a and 77b are views showing a state in which a disk R3 is contained in the third buffer 503 and the third buffer returns to the original position, ie the position shown in Figures 67a and 67b; and FIGS. 78a and 78b show that they show a state in which a pattern R4 is held in the aliasing length 504 and the aliasing length 504 returns to the original position "is from" the position shown in FIGS. 67a and 67b. Figures 79a and 79b are views showing a state in which an order is given from the operation portion allowing the reproduction of the disk R2 and the second buffer 502 containing the disk R2 separates it from the other storage means "ie" the first buffer 501, the third buffering agent 503 and the aligner softener 504; and Figures 80a and 80b are views showing a state in which the holding portion of the disk 300 and the portion of the playing disk 400 are moved to reproduce the disk R2. The figures Bla and Slb are views showing a state in which a second buffer 502 is moved towards the insertion port; and Figures S2a and 82b are views showing a state in which the disk R2 is held between the disk fixing portion 300 and the playing portion of the disk 400 and the second buffer 502 return to the original position, followed by the reproduction of the disk R2. In addition, each of the figures 67a »..., B2a is a top sectional view, and each of the figures 67b» ... »B2b ee a sectional side view taken on the line a-a. First, as shown in Fig. 67, in the state in which no disk is contained in the disk system, ie in the initial state, the first buffer 501 to the fourth buffer 504 are arranged in a close manner. a peripheral edge portion of the housing 100 on the opposite side of the insertion port 101 and other upper and lower spaces are provided between the storages. In addition, the disk reproduction portion 400 and the dispense holding portion 300 are disposed in a manner close to the upper disc roller 201 and the lower disc roller 202 disposed near the insertion port IOI »and the disc system is ready for the receipt of an order allowing the insertion of a disk from the operation portion (not shown) in a state in which a space between the disk rollers is kept to a minimum. Then a specific command that allows the disk Rl to be contained in the first buffer 501 is supplied from the operating portion. At sontinuation, the first stirrer 501 is moved, by the motion messaging portion 520 described above to move each of the storages, from the position shown in FIGS. 67a and 67b in direction B and is placed in a specific position. shown in Figures 6Ba and 68b »that is, a position in which the store 501 can contain the disk R; and the first buffer 501 is ready for insertion of the disk. When the disk Rl is inserted from the insertion port 101 as shown in FIGS. 69a and 69b, it is contained in the first buffer 501 by the disk loading mechanism 200 (FIGS. 70a and 70b), and the first buffer 501 moves in the direction A to return to the original position shown in figures 67a and 67b (see figures 71a and 71b). Prior to the insertion of the next disk R2, to adjust a height of the buffer 502 to hold the disk R2 at a height of the insertion port 101, the buffers are completely raised to a height corresponding to a buffer stage by the mechanism portion of previous movement 520 (FIGS. 72a and 72b), and then the masseter 502 to hold the dis- placement R2 ee moves in the direction B and colossus in a specific position (FIGS. 63a and 73b> .and, the disso R2 inserted from the insert port 101 is transported in the disk system by the disk load portion 200 (FIGS 74a and 74b) and is contained and held in the second buffer 502 (FIGS 75a and 75b) As shown in FIGS. and 76b »the second buffer 502 moves in the direction A to return to the original position, similarly as shown in FIGS. 78a and 78b» the disso R3 is held in the alssender terser 503 »and thus shown in FIGS. 79a and 79b, the disabout R4 is contained in the buffer store 504. In this case, as shown in FIG. 79b, the kneaders are separated from one another. To be more thickened, the second slayer 502 is separated from the first »second» and third storages 501 »503 and 504 in such a way that the space between the first storer 501 and the second storer 502 is inclined at a first angle 81 and the space between the second store 502 and the third and fourth store 503 and 504 are inclined at a second angle T2. Next »when an order is given from the operation portion (not shown)» as shown in figures 79a and 79b >; which allows the reproduction of the disk R2 »the portion of the previous movement mechanism 520 places the second buffer 502 containing the target disk R2 at a specific height at which the disk R2 can be reproduced» and tilts the other buffers to separate the second buffer 502 of this one. Then the holding portion of the disc 300 is inserted into the space between the disks Rl and R2 »and the reproducing portion of disso 400 moves in the direction A and is inserted into the space between the disks R2 and R3» with the space between the upper disc roller 201 and the lower disc roller 202 being elongated (Figure 80a and BOb). Furthermore, in order to reproduce the disk R2 as shown in figures Sla and 81b, the second buffer 502 containing the disk R2 moves in the direction B to a specific position. A sontinuasion »is shown in Figures S2a and 82b, the disk holding portion 300 is further moved in the direction A to be inserted into the space between the first buffer 501 and the second buffer 502. Similarly, the disk playback portion 400 is further moved in the direction A to inserted into the space between the second buffer 502 and the third buffer 502. Until now, the space between the upper disk roller 201 and the lower disk roller 202 is elongated to the maximum. In this way, the disk R2 is held between the reaming portion of the disk 300 and the disk playback portion 400"and then the second buffer 502 moves to the original position and releases the hold of the disk R2" followed by the reproduction of the disk. disso R2. Then operation (2) will be dessribirá. that is, the operational stage of the entire disk system in which the reproduction of the disso R2 is stopped and the disso R2 is again restented in the second buffer 502. and the disk R3 contained in the third buffer 503 is reproduced, with reference to figures B3a to 90b. Figures S3a and 83b are views showing a state in which the disk R3 is held in the massaging terser 503 and the disk R2 is reproduced; Figures 84a and 84b are views showing a state in which the second store 502 moves to a position where the second store 502 can hold the disk R2 while holding the disk R2 and the play portion of the store 400 is returned slightly to the original position as shown in Figures 67a and 67b; the figures 85a and S5b are views showing a state in which the second store 502 contains the disk R2 and is returned to the original position; and Figures 86a and S6b are views showing a state in which the movement of the disc-holding portion 300 and the disputing replication portion 400 is filled to the original positions. FIGS. 87a and 87b are views showing an assembly in which the maskers are raised while separating from each other; Figures 87a and 88b are views showing a state in which the disc holding portion 300 and the reproducing portion of stiff 400 move to the side of the third storage 503; Figures 89a and 89b are views showing a state in which the third buffer 503 moves on the side of the insertion port 101; and Figures 90a and 90b are views showing a state in which the disc R3 is held between the disc holding portion 300 and the disc reproduction portion 400 »and the third storage 503 is moved to the original position and releases the holding the R3 disk »followed by the reduction of the R3 disk. In addition »each of the figures 83a. ... »90a is a top sectional view, and each of the figures 83b» ... »90b is a side sectional view taken on line a-a. First »when a command from the operation portion» that allows the reproduction of the R3 disk. in the state in which the disk R2 is held between the holding portion of the disk 300 and the reproduction portion of the disk 400 is shown in Figures S3a and 83b for the reproduction of the disk R2 »the second webizer 502 first moves in the direction B to hold and hold the rigid R2 located in the reproduction poem. To continuation »the reproduction portion of dieso 400 releases disk R2 and returns slightly in direction A (figure 84a and 84b). The second buffer 502, which holds the disk R2 with its holding by the holding portion of the disk 3010 and the reproduction portion of the disk 400 being released »moves in the direction A to return to the original position (figures 85a and 85b > , and as shown in FIGS. 86a and 86b, not only the disso play portion 400 but also the disappliance fixing portion 300 returns to the original position, and the space between the upper disc roller 201 and the disc roller lower 202 is reduced to the minimum., to use the height of the third buffer 503 at the height of the insertion port 101, the second buffer 502 and the fourth buffer 503 are raised while separating one from the other (FIGS. 87a and 87b), and the disk holding portion 300 and the disc playing portion 400 moves in the direction A and also the space between the upper disc roller 201 and the lower disc roller 202 is elongated. Then »the disk holding portion 300 is inserted into the space between the disks R2 and R3» and the disk reproduction portion 400 is disposed substantially under the disk R3 (Figures 88a and 88b). Further »the third buffer 503 containing the disk R3 moves in the direction B up to a position in which the disk R3 can be reproduced (FIGS. S9a and 89b), and as shown in FIGS. 90a and 90b, the disk playback portion 400 also also moves in the direction A, whereby the disso R3 is held between the disk holding portion 300 and the disk playing portion 400.

After holding the disc R3 »the space between the upper disc roller 201 and the lower disc roller 202 is maximally stretched, and the third storage 503 moves in the A direction to return to the original position and releases the hold of the R3 disk »to start playing the R3 disk. Finally, the operation (3) will be described, that is, the operation is that the disk R2 is ejected during the reproduction of the disk R3, with reference to figures 90a to 96b. Figures 91a and 91b are views showing a state that is in the course of returning the disk reproduction portion 400 to the original position from the state shown in Figures 90a and 90b; Figures 92a and 92b are views showing a state in which the third buffer 503 and the disk R3 return to the original position; Figures 93a and 93b are views showing a state in which the movement of the fixing portion of the disc 300 and the reproducing portion of the disso 400 to the originals are complete; Figures 94a and 94b are views showing a state in which the storages are completely lowered; Figures 915a and 95b are views showing a state in which the second buffer 502 moves on the side of the insertion port 10L and the disk R2 is held by the disk loading mechanism 200; and Figures 96a and 96b are views showing a state in which disk R2 is ejected. In addition »each of the figures 90a» ... »96a is a top view in section. and each of figures 90b. ... »96b is a sectional side view taken in line a-a. First »when a command allows the ejection of the disk R2 from the operation portion (not shown) in the state in which the disk R3 is held between the disk holding portion 300 and the disk playback portion 400 as, shown in Figures 90a and 90b »the third buffer 503 moves to a poem where the disk R3 can hold» and holds the disk R3. Then the disk holding portion 300 and the disk reproduction portion 400 move in the direction B and the space between the upper disk roller 201 and the lower disk roller 202 is lengthened (Figures 91a and 91b). After the operation state shown in Figures 91a and 91b »as shown in Figures 92a and 92b» the third buffer 503 moves in the direction A in the state in which the disk R3 is to return to the original slot. Then, as shown in FIGS. 93a and 93b, the disengagement portion 300 moves further in the direction B to return to the original position and the space between the upper disc roller 201 and the lower disc roller 202 is reduced. to the minimum. Also »to adjust the height of the second buffer 502 at the height of the insertion port? Oo 101 »the stokers enter completely in closed contact with each other and move (figures 94a and 94b). In this manner »as shown in Figures 96a and 96b» the second buffer 502 containing the disk R2 moves in the direction B and the disk R2 is ejected by the disk loading portion 200. According to the system of disk configured as described above »the spaces in which a base plate of the drive portion 510 of the disk containment mechanism 500 and the like can be provided and secured in the housing in both a portion on the first storage and a portion under the storage room »it is possible to eliminate an unnecessary space and minimize the length of the disk transport path as seen from the top, and to improve the miniaturization of the disk system. In addition, it is possible to freely insert or eject the discs one by one, and thus improve the utility of an operator. Since the upper disc roller and the lower disc roller can move downward and upward respectively, it can ensure a neat space for reproducing a gap in a spacing between the upper disc roller and the lower disc roller. . This makes it possible to reduce a space due to disk space, and thus miniaturize the disk system.

LOL While the first modality has been described with respect to the reproduction of disks, the operasional mode of the disks to which the present invention is apiable is not limited thereto. For example, the same effect can be obtained even when the present invention is applied to other operational modes of discs such as recording discs and erasing discs to erase information recorded on discs.

Mode 2 In continuation a disso system according to the second embodiment of the present invention will be broken with reference to Figs. 97a to 102b. Although in mode 1 the dispense loading mechanism 200 is shown as shown in FIG. 6 a to 6 d, it can be configured as shown in FIGS. 97 a to 102 b with the same effect. Figures 97a to 99b show an essential portion of a disk transport mechanism 200 on one side of the upper disk roller 201; wherein Figures 97a and 97b are front views of the essential portion; Figures 98a and 98b are top views of the essential portion; and Figures 99a and 99b are side views in section of the essential portion.

In addition »each of figures 97a. 98a and 99a show a state in which a disk R is held, and each of the figures 97b, 9Sb and 99b shows a state in which the disk R is released. Figures 100a to 102b show an essential portion of the mechanism of transportation of disk 200 on one side of lower disc roller 202 »where figures 100a and 100b are front views of the essential portion; the figures lOla and 101b are top views of the essential portion; and Figures 102a and 102b are sectional side views of the essence. In addition, each of the figures 100a. 101a and 102a show a state in which a disk R is held, and each of the figures 100b. lOlfo and 102b show a state in which the disk R is released. First, a configuration and operation of the upper disk roller portion will be described. In Figs. 97a to 99b »the reference number 601 indicates an upper roller arm having an end for supporting the upper disc roller 201 and also having in a portion a pin 6011; 602 is a portion of the end of a slide 304 having in one portion a pin 6021; and 603 is an open joint having at one end a contact portion 6031 that comes into contact with the pin 6021 formed in the end portion 602 of the slide 304. As shown in FIGS. 99a and 99b, the portions of projection 6022 to 6024 are formed in a lateral euperfisie of the end portion 602 of the slide 304.

The reference number 604 indicates a cam plate open to the roller having in one portion a sliding hole 6041 in which the pin 6011 formed in the upper roller arm 601 moves slidably; and 605 is a spring having one end 6051 embedded with a portion 602 of a housing 100 and the other end 6052 coupled with the cam plate open to the roller 604, where the end 6051 and the other end 6052 are compressed together. The operation of the upper disc roller will be dismantled later. First, in a case different from that of the disk reproduction R "ie in the case where the disk R is held between the upper disk roller 201 and the lower disk roller 202» the end portion 602 of the slide rail 304 presses the cam plate open to the roller 604 by the pin 6021 in the direction B shown in FIGS. 98a and 98b. In conssuensia »the spring 605 extends beyond the usual length» and the aperture line 603 is in the standart are the pin 6021 by a bypass force of the spring 605 forced in the direction where the spring 605 returns to the original length. Then, in the case of the reproduction of the disso R "because the slider 304 moves in the direction A shown in Figs. 9Ba and 98b» the end portion 602 of the slide 304 also moves in the direction A . As a result, the opening link 603 secured in contaste with the pin 6021 formed in the end portion 602 is made rotatable in the C direction, whereby the cam plate, the roller opening 604 »which is conical and secures to the connection of opening 603 and is bypassed by the spring 605 in the direction B, it can be pushed in the direction B. By pulling the open cam plate on the roller 604 in the direction B, the pin 6011 formed in the upper roller arm 601 slides in the sliding hole 6041 formed in the cam plate open to the roller 604 in a position shown in Fig. 99d, and in this way is raised to a height "d", and correspondingly the disc upper roller 201 is raised approximately to the height "d". In addition, a configuration and operation of the lower disc roller will be described. In figure 100a to lOOb »the reference number 611 indicates a lower roller arm having in a portion a contact portion 6111 with which part of the projection portions 6022 to 6024 formed in the end portion 602 of the slide 304 come into contact. Next, the operation of the lower disc roller will be described. First, in a different case from the reprojection of the disk R, that is in the case where the disk R is held between the upper disk roller 201 and the lower disk roller 202, since the slider 304 moves in the ejection D: the sonotrode portion 6111 of the lower roller arm 611 does not come into contact with the projection portions 6022 to 6024 formed in the end portion 602 of the slide 304 and the lower roller arm 611 is drifted in the direction F by a bypass force of a bypass portion (not shown) to usually derive the direction F in it. Then »in the case of the reproduction of the disk R» due to the slider 304 it moves in the direction E shown in the figure 102a and 102b »the end portion 602 of the sliding guide 304 also moves in the direction E. Accordingly» the projecting portions 6022 to 6024 formed in the end portion 602 of the guide d The slide 304 comes into contact with the contact portion 6111 of the lower roller arm 611 »whereby the contact portion 6111 is rotated in the direction H around a rotation arrow 6112. Accordingly. the lower disc roller conested to the lower roller arm moves in the G direction. With this configuration »the disc roller portion can be operated with precision with a simple structure» so that it is still possible to improve the sonfability of the disc disk .

In the disc roller portion 200 of the embodiment 2, the upper disc roller is shown in Fig. 97a to 99b and the lower disc roller is shown in Fig. 100a to 102b.
