Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device for a disc-shaped recording medium such as an optical disc or a magneto-optical disc, and more particularly to one disc-shaped recording from a disc accommodating portion accommodating a large number of disc-shaped recording media. It is suitable for use in a recording device for a disk-shaped recording medium, in which a medium is taken out and an information signal is recorded on the taken-out disk-shaped recording medium.

[0002]

2. Description of the Related Art Recently, as a disc-shaped recording medium, a read-only optical disc, an optical disc capable of recording once, a magneto-optical disc capable of recording many times, etc. have been proposed and put into practical use. Then, those having various functions as devices for recording and / or reproducing information signals to and from these disc-shaped recording media (hereinafter collectively referred to as disks) have been supplied to the market.

Usually, many recording and / or reproducing apparatuses for disk-shaped recording media (hereinafter, simply referred to as recording / reproducing apparatuses) are intended for individual use, and most of them are the users themselves. Then, one disc is set in the recording / reproducing apparatus and used. In addition, at present, for commercial use, a system has been developed in which a favorite song is recorded on a so-called raw disc on which nothing is recorded, and the recorded disc is sold to customers as is. I am trying to use the device. That is, when a customer requests a recording, the seller himself sets a raw disc in the recording / reproducing device,
It records the music specified by the customer on a disc and sells the disc to the customer.

The automation of this system has been advanced and various mechanisms have been proposed. Two mechanisms will be typically described. One is a disk storage device capable of storing a large number of disks and, for example, vertically movable, and one disk is taken out from the disk storage section. It is composed of a disc carrier device and a recording / reproducing device which is installed, for example, in the lower part of the disc storage device and moves up and down together with the disc storage device.

Then, for example, by operating the start button, the disc storage portion is moved up and down so that a predetermined disc in the disc storage device faces the disc carrier device. After that, the disk at the opposite position is taken out from the disk storage device by the disk carrier device and the disk is temporarily stored in the carrier device. Then, the recording / reproducing device is moved up and down together with the disc housing device so that the recording / reproducing device and the disc carrier device face each other. Then, the disc accommodated in the disc carrier device is conveyed to the recording / reproducing device side, and an information signal is recorded on the conveyed disc, and in the above example, music is recorded.

After the recording is completed, the disc is again conveyed into the disc carrier device, and the disc is temporarily accommodated in the disc carrier device. After that, the disc storage device is moved up and down so that the position where the ejected disc was stored faces the disc carrier device, and then the disc temporarily stored in the disc carrier device is moved to the disc storage device. It is transported to the original position inside and a series of operations is completed.

As the work performed by the seller, all that is required is to take out the disc returned to the original position from the disc storage device and sell it to the customer.

The other mechanism has substantially the same components as the above-mentioned mechanism, but is different in that the disc housing device and the recording / reproducing device are fixed and the disc carrier device moves vertically. That is, the carrier device moves up and down to take out a predetermined disc from the storage device,
The disk thus taken out is conveyed to a recording / reproducing apparatus. After recording, the carrier device moves up and down again to return the disc mounted in the recording / reproducing device to the original position of the disc storage device.

Also in this mechanism, like the above mechanism,
The work of the seller will be greatly simplified.

[0010]

However, in the recording / reproducing apparatus having the above-mentioned disc accommodating device and disc carrier device, the following problems occur because the disc accommodating device and the disc carrier device move relative to each other. That is, first, in the case of the former mechanism, since the disk storage device itself moves in the vertical direction, at least twice the space (installation space) as that of the disk storage device is required, and the device itself becomes extremely large. There's a problem.

Further, in the latter mechanism, when the disk existing at the uppermost end or the lowermost end is taken out, a part of the carrier device jumps upward from the uppermost end or downward from the lowermost end, and the space of the protruding part is Since it becomes a dead space, there is a problem that there is a limit to downsizing of the device.

[0012] In both cases, since the recorded disc is returned to the original position again, there is a problem that the intervention of a person (seller) is inevitable and the disc cannot function as an automatic vending machine. is there.

The present invention has been made in view of the above problems, and an object thereof is a storage unit capable of storing a large number of discs and a recording / reproducing means for recording one disc-shaped recording medium from the storage unit.

When the shafts 68 of the stopper members 62a and 62b are in the first position, the stopper members 62a and 62b are inclined to each other in a V-shape due to the positional relationship of the double hole 69. It becomes a shape, and is in a state of being easily pressed from above.

Further, in this example, the stopper member 62
2 on the rear end side of the locking pieces 63 in a and 62b, respectively.
Two notches 70a and 70b are provided. The positions where the notches 70a and 70b are formed are different between the one stopper member 62a and the other stopper member 62b. This will be described in detail later, but the cartridge 55
This is for defining the mounting direction of the recording / reproducing apparatus in the storage unit 1. That is, the recording surface of the optical disk D housed in the cartridge 55 is specified, and if the recording surface is not oriented in a predetermined direction with respect to the housing unit 1, recording on the optical disk D becomes impossible. Because.

When the cartridge 55 is used, for example, after the cartridge assembling process in the factory,
At the time of packaging, a large number (for example, 25) of optical discs D
Is stored in the cartridge 55 with its recording surface oriented in one direction. First, as shown in FIG. 8, the user pulls out the unit main body 11 from the outer casing 12 (see FIG. 1) of the storage unit 1 in the recording / reproducing apparatus, and opens it in the opening on the depth side which is always open. The cartridge 55 is inserted downward.

In this case, even if the cartridge 55 is faced downward, the optical disc D housed in the cartridge 55 will not have the stopper members 62a and 62a as shown in FIG.
There is no problem because the dropout is prevented by 2b. Further, when the cartridge 55 is packed and transported, each optical disc D collides with the partition plate 56, but the height of the partition plate 56 is restricted by the width of the non-recording area in the circumferential portion of the optical disc D. Therefore, there is no inconvenience that the recording area of the optical disc D is scratched.

A pair of positioning projections 71a and 71b, which project inwardly from each other, are provided on the inner upper portion of the opening of the unit main body 11 by, for example, cutting and raising a sheet metal, and the cartridge 55 is provided. When inserted in the correct direction (in this example, the recording surface of the optical disc D is directed toward the depth side of the unit body 11), the notches 70a and 70b formed in the locking piece 63 of the cartridge 55 are the same as those described above. The protrusions 71a and 71b are so-called reliefs, and the cartridge 55 can be inserted into the unit body 11. Conversely, the cartridge 55
When it is attempted to insert the lock piece 6 in the wrong direction, the protruding pieces 71a and 71b are locked by the locking piece 6 of the cartridge 55.
It hits the upper end of No. 3 and can not be inserted any more. Therefore, the cartridge 55 is set in the unit main body 11 so that the recording surface of the optical disc D always faces the depth side, and the erroneous mounting of the cartridge 55 can be prevented.

Further, since the stopper members 62a and 62b of the cartridge 55 are inclined in the V-shape as described above, during the process of inserting the cartridge 55, the protruding pieces 71a and 71b are stopped by the stopper members 62a and 62b. Abut on 62b. When the insertion of the cartridge 55 further progresses, the protruding pieces 71a and 71b move to the stopper member 6
The plates 2a and 62b are pressed so that their plate surfaces face the vertical direction. By the pressing by the projecting pieces 71a and 71b, the shafts 68 of the stopper members 62a and 62b proceed from the inner hole 69a of the two continuous holes 69 to the outer hole 69b side beyond the communicating portion, and further to the cartridge 55. When the contact plates 61a and 61b of the cartridge 55 contact the upper surface of the side plate 17 of the unit main body 11 by inserting the shaft 68, the shaft 68 is fitted into the hole 69b on the outer side (see FIG. 7).

In this example, as shown in FIG.
In the vicinity of the lower portion of the long hole 72 along the formation direction of the double hole 69.
To form. Therefore, the shaft 68 is the double hole 6
When passing through the communicating portion of 9, the lower side of the communicating portion is elastically deformed toward the elongated hole 72, so that the shaft 68 easily advances to the hole 69b on the outer side. And this axis 68
When is inserted into the hole 69b on the outer side, the communicating portion elastically returns, and the shaft 68 is reliably fitted into the hole 69b on the outer side.

At this time, the shaft 68 is positioned at the second position for releasing the contact of the optical disc D by the locking piece 63, whereby each optical disc D falls below the regulation and falls downward. It will be accommodated in the unit main body 11. In this case, in the cartridge 55, the arrangement pitch of the grooves 60 formed by the partition plate 56 is set to the three feed screws 31a provided on the unit main body 11,
If the screw pitches of 31b and 31c are the same, the optical disc D falling from the cartridge 55 is
Insert one sheet into the corresponding thread groove of each of the three feed screws 31a, 31b, and 31c.
It will be supported by points.

Then, the cartridge 55 is removed from the unit main body 11, and the unit main body 11 is further attached to the outer casing 1.
2 and the setting of the optical disc D in the storage unit 1 is completed. The completion of this setting is electrically recognized by the output signal from the limit switch 51 (see FIG. 2) provided on the outer casing 12. Then, for example, by operating a start button (not shown), the motor 33 of the rotary drive mechanism 23 is driven, and the three feed screws 31a, 3
1b and 31c will rotate respectively. The 25 optical disks D supported at three points by the respective screw grooves of the three feed screws 31a, 31b and 31c are
By rotating the book feed screws 31a, 31b and 31c,
The sheets are sequentially conveyed to the front side of the unit main body 11 (see FIG. 5).

As shown in FIG. 5, the unit main body 11 has a position detecting sensor mechanism 73 and a feed-out mechanism 74 mounted on the front side upper surface of the bottom plate 16. As shown in FIG. 9, the position detection sensor mechanism 73 rotates about a support shaft 75 protruding from the bottom plate 16, and an arm member 78 having a contact piece 76 on one side and a shutter portion 77 on the other side, and a shutter. The optical sensor 79 is arranged so as to straddle the portion 77 in the vertical direction. The contact piece 76 extends inward of the unit main body 11 and is positioned so that the front end of the contact piece 76 contacts the optical disc D that is sequentially conveyed.

The shutter section 77 includes two shutter pieces 77.
a and 77b and a notch 77c formed between the shutter pieces 77a and 77b. The optical sensor 79 is configured by attaching a light emitting element to one side and a light receiving element to the other side. Further, the arm member 78 is
A projection 80 protruding upward is integrally formed on the upper surface of the shutter 77 side of the support shaft 75. And
A tension coil spring 82 is attached between the protrusion 80 and a stopper piece 81 provided by cutting and raising the bottom plate 16.

Therefore, the natural state (initial state) of the arm member 78 is set by the bias of the coil spring 82.
The front end surface of the arm member 78 is in contact with the stopper piece 81. At this time, the optical sensor 79 is shielded by the shutter piece 77a on the depth side. The optical disc D has three feed screws 31a,
When the optical disc D is sequentially conveyed to the front side by the rotation by 31b and 31c, the first optical disc D comes into contact with the contact piece 76. When the optical disc D is further conveyed to the front side, the optical disc D pushes the contact piece 76 in the front direction against the bias of the coil spring 82, so that the arm member 78 centers on the support shaft 75. It will rotate to. With the rotation of the arm member 78, the light blocking of the optical sensor 79 by the shutter piece 77a is gradually released, and when the light blocking state is completely released, the first optical disc D is the frontmost in the unit main body 11. It is located at the side position, that is, at a predetermined feeding position.

On the other hand, as shown in FIG. 11, the feeding mechanism 74 basically has a motor 83 and a gear 8 with a cam groove.

And an engaging piece 89 that engages with the interlocking plate 88 transmitted to the.

A cam groove 90 having an eccentric cam shape is formed on the front plate surface of the gear 84 with cam groove, and the cam groove 90 projects laterally from the upper end of the interlocking plate 88. The first pin 91 is inserted.

Further, as shown in FIG. 11, partition plates 92a and 92b are fixed on the front side and the depth side of the delivery mechanism 74 by, for example, screwing. Of these, partition plates 92a and 92b on the front side are provided. The support shaft 93 is inserted (see FIG. 10), and the push-up arm member 85 and the communication plate 88 are rotatably attached to the support shaft 93. The push-up arm member 85 and the interlocking plate 88
As shown in FIG. 10, a tension coil spring 94 is attached between the respective lower portions, and the lower end surface of the push-up arm member 85 contacts the second pin 95 provided on the interlocking plate 88. Then, these lifting arm members 85 are
And the interlocking plate 88 move almost as a unit.

Then, by the rotational drive of the motor 83,
The gear 84 with a cam groove rotates, and with the rotation of the gear 84, the first pin 91 of the interlocking plate 88 moves up and down along the cam groove 90, and as a result, the arm 87 centers on the support shaft 96. It will rotate vertically.

The arm 87 is located at the frontmost position in the unit main body 11, that is, at a predetermined feeding position, and the optical disc D at that position is lifted upward as the arm 87 rotates upward. become. Motor 83
Is activated based on the output signal from the optical sensor 79 of the position detection sensor mechanism 73. That is, the shutter piece 77
It is activated based on the output signal (signal level) when the light blocking of the optical sensor 79 by a is completely released.
At this time, since the leading optical disc D is located at the delivery position, the leading optical disc D is lifted upward.

The motor 83 in the feeding mechanism 74
Is connected to the drive circuit before it, and this drive circuit is
For example, a start signal (trigger) from the system controller
Based on the above, the drive current is applied to the motor 83 for a predetermined time. This time is the time until the arm 87 moves from the lowermost position to the uppermost position by the rotational driving of the motor 83 and returns to the lowermost position again. When the arm 87 returns to the lowermost position, it remains stopped until the next activation signal is supplied.

As shown in FIG. 3, the unit body 11 has an opening 101 formed between the opening / closing lid 20 and the front plate 18, and the side plate has a portion corresponding to the opening 101. As shown in FIG. 11, the guide groove 10 is formed inward.
The guide member 103 formed with 2 is fixed. The opening 101 and the guide groove 102 of the guide member 103.
Are formed at positions corresponding to the optical disc D at the above-mentioned delivery position. In addition, as shown in FIG.
The opening 104 is formed at a location corresponding to the opening 101 of the second item. Therefore, the optical disc D in the delivery position is lifted up by the arm 87 of the delivery mechanism 74 and delivered above the outer casing 12 through the opening 101 and the guide groove 102 of the unit main body 11 and the opening 104 of the outer casing 12. Be done.

Next, regarding the recording / reproducing unit 2, FIG.
This will be described with reference to 2. This recording / reproducing unit 2
Is a spindle motor (not shown) having a turntable 110 on which the optical disc D is mounted at the tip thereof.
And an optical head 111 that irradiates the recording surface of the optical disc D with a laser beam to form pits according to the information signal. The optical head 111 uses the known slide mechanism, for example, a biaxial linear motor, to drive the optical disc D.
It is possible to move in the radial direction.

These spindle motor and optical head 11
1 and the linear motor are housed in a unit case 112 formed of a metal plate in a box shape. The turntable 110 is arranged at a position protruding upward through a circular opening 113 provided on the upper surface of the unit housing 112, and the optical head 111 faces upward through the substantially rectangular opening 114. It is located in.

The unit casing 112 is fixed to the upper plate 14 of the outer casing 12 of the storage unit 1 by screwing or the like. A positioning projection 115 is formed on the upper surface of the unit housing 112 so as to project upward. When the loading mechanism unit 3 descends, the projection 115 is inserted into a positioning hole 116 formed in the lower surface of the casing 123 of the loading mechanism unit 3 to allow the loading mechanism unit 3 to move to the recording / reproducing unit. Positioning is done at 2.

Next, the loading mechanism unit 3 will be described with reference to FIGS. The loading mechanism unit 3 includes a disc holder 121,
A metal casing 1 that accommodates the disc holder 121 so that it can be projected and inserted through an insertion / removal opening 122 (see FIG. 14).
23 and. As shown in FIG. 15, in this case 123, a support shaft 124 projecting laterally from the front side portion of the side plate 112 a of the unit case 112 in the recording / reproducing unit 2 is penetrated, and the support shaft 124 is attached to the support shaft 124. It is fixed to a pair of L-shaped inner plates 125, which are rotatably supported, by, for example, screws. Outside plates 126 are arranged on the outer sides of the inside plate 125 in the lateral direction,
The outer plate 126 is rotatably supported by the support shaft 124. A protective plate 127 is fixed to the upper surfaces of the pair of outer plates 126 by screwing or the like.

As shown in FIG. 17, the disc holder 121 has a mounting portion 128 on which one optical disc D is mounted, and the mounting portion 128 has the recording / reproducing unit 2 described above.
A circular opening 129 is formed at a position corresponding to the turntable 110, and a rectangular opening 130 is formed over the range in which the optical head 111 moves. Similar openings 131 and 132 are formed in the bottom plate 123a of the box 123 that houses the disc holder 121.

On the front side of the disc holder 121 (that is, on the side of the insertion / removal opening 122 of the box 123), the optical disc D is sandwiched from both sides, and the optical disc D is moved to a predetermined accommodating position of the disc holder 121 by rotational driving. A roller driving unit 133 that is insertable and removable is provided. Here, the predetermined accommodation position is a position where the entire center hole of the optical disc D faces downward through the circular opening 129 of the disc holder 121. This position detection can be performed by a known optical sensor or the like, and a detection signal from this sensor electrically determines whether or not the optical disc D has reached the predetermined accommodation position.

The roller driving means 133 is composed of two rollers 134a arranged in parallel along the insertion direction of the optical disc D.
And 134b and these two rollers 134a and 13b.
Drive roller 135 disposed above the center of the arrangement direction of 4b
Have and. In the illustrated example, the two rollers 134a and 134b are installed between a pair of support plates 136 fixed to both side surfaces of the disc holder 121, and the support plate 13 is provided.
The shafts 137a and 137b provided on the shaft 6 are used as shafts for rotation.

The driving roller 135 is composed of a metal shaft 138 extending in the axial direction and a rubber roller 139 fixed so as to cover the shaft 138. And
As shown in FIG. 18, the ends of the shaft 138 of the drive roller 135 are rotatably attached to the free ends of a pair of rotating arms 140 rotatably attached to both side surfaces of the disc holder 121.

In particular, a pinion 143 meshing with one gear 142 of a rotary drive mechanism 141, which will be described later, is fixed to one end of the shaft 138. A mounting piece 144 that projects obliquely downward is integrally provided at the center of rotation of the rotating arm 140, and a projecting piece 145 that projects laterally from the side surface of the mounting piece 144 and the disc holder 121.
An extension coil spring 146 for constantly urging the drive roller 135 downward, that is, for urging the drive roller 135 toward the two rollers 134a and 134b is attached therebetween.

Further, the shaft 1 of the drive roller 135 is
Both ends of 38 are connected to the disc holder 121 via corresponding levers 147 and link members 148, respectively. Each lever 147 is rotatably attached to the outer surface of a partition plate 149 formed near the center of the side surface of the disk holder 121 via a support shaft 150.

Each lever 147 has a lever body 151 extending from the center of rotation to the front side.
51 is a contact piece 15 protruding downward from the center of rotation.
2 and as shown in FIGS. 17 and 20, the lever body 15
A pressure regulating plate 153 projecting inward of the disc holder 121 is integrally formed on the inner surface of the front side of 1. Also,
As shown in FIG. 18, a support shaft 154 for rotatably attaching the link member 148 is provided at the front end of the lever body 151.

The disc holder 121 is shown in FIGS.
As shown in FIG. 0, the opening 1 is formed near the partition plate 149.
55 is formed, and the abutting piece 15 of the lever 147 is formed.
2 is projected downward through the opening 155. Further, the partition plate 149 has a tapered surface 149a in the front portion of the mounting portion of the support shaft 150, and the pressing restriction plate 153 of the lever 147 of the disk holder 121 passes through the space formed by the tapered surface 149a. It is designed to project inward.

Each link member 148 corresponds to the rotating arm 1 described above.
It is configured to be bent so as to avoid the center of rotation of 40.

In the lever 147, the urging force of the tension coil spring 146 attached to the rotating arm 140 is transmitted via the rotating arm 140 and the link member 148, and the contact plate 152 is always supported by the support shaft 150. It is designed to be urged to rotate downward around the center. Therefore, as shown in FIG. 18, the contact plate 152 is always projected from the opening 155 of the disc holder 121.
In such a state, for example, when the contact plate 152 is rotationally biased upward, as shown in FIG.
51 rotates about the support shaft 150 and lifts the link member 148 upward. Therefore, the lift of the link member 148 causes the drive roller 135 to rotate the rotating arm 140 against the bias of the tension coil spring 146. It will rotate upward about the center.

As shown in FIG. 20, the rotary drive mechanism 141 for rotationally driving the drive roller 135 is composed of a motor 156 installed at the rear portion of the disk holder 121 and a speed reduction mechanism 157 by a gear train. Then, the rotational force of the rotation shaft of the motor 156 due to the rotational driving of the motor 156 is transmitted to the reduction mechanism 157 via the belt 158 with internal teeth, and the rotation force of the rotation shaft of the motor 156 is reduced. The speed is reduced by the mechanism 157, and finally the shaft 1 of the drive roller 135 is passed through the pinion 143.
38 is transmitted. The motor 156
Is a type that performs normal rotation and reverse rotation.
The drive roller 135 also rotates in the direction in which the optical disc D is drawn into the disc holder 121 and in the direction in which it is sent outward from the disc holder 121, as the motor 156 rotates forward and backward.

Here, the outer shape of the driving roller 135 and the two rollers 134a and 134b is such that the central portion in the longitudinal direction has the smallest diameter and the diameters gradually increase toward the left and right ends thereof. When the optical disk D is sandwiched by the drive roller 135 and the two rollers 134a and 134b, the two rollers 134a and 134b support the recording surface of the optical disk D at four points and the drive roller 135 makes the other surface at two points. It is supposed to support.

In particular, the two rollers 134a and 134b
As described above, since the central portion in the longitudinal direction has the smallest diameter and the diameter gradually increases toward the left and right ends, four points in the outer peripheral portion of the non-recording area in the recording surface of the optical disc D are recorded. I will support you. These support points continuously change as the optical disc D moves due to the rotation of the drive roller 135, but the four points in the outer peripheral portion of the non-recording area are always the two rollers 134a and 13 described above.
It will be supported by 4b.

Therefore, the recording / removing operation of the optical disc D by the roller driving means 133 does not damage the recording surface of the optical disc D, particularly the surface corresponding to the recording area, and the subsequent recording and / or recording of the information signal on the optical disc D and / or Regeneration will be performed well.

Further, the driving roller 135 is replaced by the two rollers 1.
Since they are arranged above the center of the arrangement direction of 34a and 134b, when the optical disc D is conveyed by the roller drive means 133, the roller 134a on the front side and the drive roller 1 are arranged.
35, a downward couple acts, but at the same time, an upward couple acts on the depth side roller 134b and the drive roller 135, so that these couples are balanced and, as a result, the vertical force on the optical disc D is canceled. .
Therefore, the optical disc D by the roller driving means 133 is
When the optical disc D is conveyed, the plate surface of the optical disc D is stably conveyed substantially along the conveying direction of the roller driving means 133, and the end face of the optical disc D collides with the ceiling portion or the bottom portion of the disc holder 121. Avoided.

When the roller driving means 133 inserts the optical disc D into the disc holder 121, the optical disc D moves below the pressure regulating plate 153 of the lever 147. Therefore, even if the optical disc D tries to be lifted upward due to, for example, vibrations when the optical disc D is inserted, the upward lifting is restricted by the pressure regulating plate 153, so that stable conveyance to the optical disc D is further ensured. .

On the other hand, a slide mechanism 161 for projecting / inserting the disc holder 121 through the insertion / removal opening 122 into the housing 123 for accommodating the disc holder 121.
Is provided. This slide mechanism 161 is shown in FIG.

The rotational force of 2 is applied to the rack 163 via the pinion 164.
To be transmitted to. The motor 162 is
It is a type that performs normal rotation and reverse rotation, whereby the disk holder 121 slides in a direction in which it is projected and inserted through the insertion / removal opening 122 of the box 123 with the forward rotation and reverse rotation of the motor 162. Become.

Further, the gear 1 in the preceding stage of the pinion 164.
The 66 has a concentric hole 167 formed in the upper surface thereof, and a projection 169 projecting toward the central axis 168 of the gear 166 is integrally formed on the inner wall of the hole 167. Also,
In the side plate 123b of the casing 123, the operation plate 170 is provided at a position corresponding to the gear 166, and the side plate 123b of the casing 123 is provided.
It is attached so that it can move back and forth. This back-and-forth movement is achieved by an elongated hole 171 provided in the operation plate 170 and a stopper piece 172 protruding from the side plate 123b and inserted into the elongated hole 171.

Further, the operation plate 170 is integrally formed with a substantially U-shaped operation piece 174 projecting toward the disc holder 121 side at the upper part thereof and having a notch 173 formed from the end face toward the center. Further, a mounting piece 175 that also projects toward the disc holder 121 is integrally formed in the lower portion corresponding to the operation piece 174. A pin 176 protruding downward is integrally formed on the lower surface of the mounting piece 175.

With such a structure, when the gear 166 rotates in one direction by the rotational driving (for example, normal rotation driving) of the motor 162, the gear teeth of the gear 166 and the pinion 1 are rotated.
64 engages with each other, and the pinion 164 is driven to rotate in association with this engagement, so that the disk holder 121 is moved to, for example, the casing 12.
It moves in a direction projecting outward from the insertion / removal opening 122 of No. 3.
At this time, the internal contact of the position detection switch 177 is turned "off". When the disc holder 121 moves (projects) to a certain range, the protrusion 169 of the gear 166 causes the operation plate 17 to move.
By engaging the pin 176 of the mounting piece 175 at 0, the operation plate 170 is moved, for example, in the front direction. By this movement of the operation plate 170, the switch piece of the position detection switch 177 is rotated in the front direction, and this rotation turns on the internal contact, for example, and outputs a stop signal to the motor 162. The motor 162 stops its rotational drive (normal rotation) based on the stop signal from the switch 177.
At this time, in the disc holder 121, as shown in FIG. 23, half or more of the mounting portion 128 is in a state of protruding from the insertion / removal opening 122 of the housing 123.

When the motor 162 is driven in the reverse rotation from the above state, the pinion 1 rotates while the gear 166 rotates in the reverse direction.
Will mesh with 64. Then, by the reverse rotation drive of the pinion 164 accompanying this engagement, the disc holder 1
21 moves through the insertion / removal opening 122 of the box 123 in the direction to be inserted inward. At this time, the internal contact of the position detection switch 177 is turned "off". When the disc holder 121 is moved (inserted) to a certain range, the protrusion 169 of the gear 166 is again moved to the pin 176 of the operation piece 174.
To move the operation plate 170 in the depth direction. By the movement of the operation plate 170, the switch piece of the position detection switch 177 is rotated in the depth direction,
By this rotation, the internal contact is turned on again, and the stop signal is output to the motor 162. The motor 162 stops its rotational drive (reverse rotation) based on the stop signal from the switch 177. At this time, the disc holder 121
Is completely inserted into the box 123 (see FIG. 1).

The rotation angle in the positive direction is shown. Note that FIG.
In FIGS. 2 to 59, SLD = y (mm) indicates the amount of displacement of the inner plate, and the-sign indicates downward movement.

32 to 59, the innermost member (main gear 204) on the paper surface is indicated by a dotted line, and the member (medial diameter gear 207, guide rail 209, first and second cams) located in front of the member is indicated by a dotted line. Parts 210a and 210b, driven gear 22
1, the first and second pins 222a and 222b) are indicated by a thin solid line, the member (outer side plate 126) in front of them is indicated by a dashed line, and a member (small-diameter gear 208, The rack member 224) is shown by a thick solid line, the member (inner plate 125) in front of it is shown by a chain double-dashed line,
The foremost member (guide member 231) is indicated by a broken line.

Further, FIGS. 60 to 70 are similar to FIGS. 32 to 59.
Among the members shown by, the medium-diameter gear 20 in the main gear 204
7, guide rail 209, first and second cam portions 210a
And 210b and the driven gear 22 on the outer plate 126.
1 shows a flow of each operation of one and a pair of pins 222a and 222b.

First, in the initial state, as shown in FIGS. 14 and 32, the pair of pins 222a and 222b on the outer side plate 126 are arranged vertically, and the loading mechanism unit 3 fixed to the inner side plate 125 is brought into a horizontal state. The mounting portion 128 of the disc holder 121 is supported and faces the recording / reproducing unit 2.

At this time, the box 123 of the loading mechanism unit 3 is positioned at the top dead center as shown in FIG. 15, and the tension coil spring 232 is in the natural state. Also, of the pair of pins 222a and 222b,
One of the pins 222a located above is guided by the guide rail 209.
Has been inserted into the. In addition, the rack member 22
4 has a positional relationship in which the gear portion 227 faces the non-driving portion 208a of the small diameter gear 208 in the main gear 204.

Then, for example, when the motor 203 of the rotary conveyance mechanism 201 is driven to rotate the main gear 204 in the drawing, for example, leftward at a constant angular velocity ω, FIGS.
As shown in FIG. 1, one of the pins 222a is connected to the guide rail 20.
9 relatively moves in the direction of the first cam portion 210a. At this time, the outer side plate 126 (and the inner side plate 125) remains stopped. Then, as the main gear 204 rotates,
As shown in FIGS. 34 to 36 and 62 to 64, the pin 222a relatively moves within the rail of the first cam portion 210a.

In this case, the center of curvature of the first cam portion 210a is different from the center of rotation of the main gear 204, and the radius of curvature is made larger than the radius of curvature of the guide rail 209, so that the guide rail 209 moves relatively. As the main gear 204 is rotated, the rail side wall of the cam portion 210a moves the pin 222a toward the front side because the pin 222a is gradually opened outward with respect to the traveling direction that draws the circumference of the pin 222a. It will be pressed. That is, the rotational force of the main gear 204 is transmitted to the pin 222a through the cam portion 210a, and the outer plate 126 (and the inner plate 125) undergoes an equiangular acceleration motion as the main gear 204 rotates, and the driven gear is driven. 22
The first gear portion 221a is rotated in the direction in which it meshes with the medium diameter gear 207 of the main gear 204.

Then, the pin 2 formed by the cam portion 210a.
The outer plate 126 (and the inner plate 125) reaches the same angular velocity as that of the main gear 204 by applying the rotational force to 22a. At this time, as shown in FIG. 37, the gear portion 221a of the driven gear 221 and the medium diameter gear 207 start to mesh with each other,
The pin 222a is disengaged from the first cam portion 210a.

As the main gear 204 rotates, the medium diameter gear 207 and the gear portion 221a of the driven gear 221 mesh with each other.
5, the outer plate 126 (and the inner plate 125)
Performs the same angular velocity motion as the main gear 204,
The direction in which the pair of pins 222a and 222b are aligned with the horizontal line,
That is, the loading mechanism unit 3 fixed to the inner plate 125 rotates in the upright direction.

Further, as the main gear 204 rotates, as shown in FIG.
2 and FIG. 66, this time the other pin 222
b enters into the rail of the second cam portion 210b. The center of curvature of the second cam portion 210b is different from that of the main gear 20.
Unlike the center of rotation of No. 4, the radius of curvature is set to be larger than the radius of curvature of the guide rail 209, and gradually closes inward with respect to the traveling direction that describes the circumference of the other pin 222b. As the main gear 204 rotates, the rail side wall of the cam portion 210b pushes the pin 222b upward. That is, the rotational force of the main gear 204 is transmitted to the pin 222b through the cam portion 210b, and the outer plate 126 (and the inner plate 125) is decelerated with a uniform angular acceleration as the main gear 204 rotates. The gear portion 221a of the driven gear 221 and the medium-diameter gear 207 of the main gear 204 are rotated in a direction to release the mesh.

When the main gear 204 further rotates,
As shown in FIGS. 43 and 44 and FIGS. 67 and 68, the outer plate 126 (and the inner plate 125) has the cam portion 21.
0b rail rotates so that the pin 222b is guided to the guide rail 209 side, and the pin 222b moves to the guide rail 2 side.
When it reaches within 09, as shown in FIGS. 45 and 69,
It is rotatably conveyed to a position rotated by 90 ° from the initial state.

That is, as shown in FIG. 29, the loading mechanism unit 3 is rotatably conveyed to a position where the insertion / removal opening 122 of the housing 123 of the loading mechanism unit 3 faces the upper opening 104 of the outer casing 12 of the storage unit 1. Become. At this time, the switch piece 212a of the position detection switch 212 comes into contact with the side end surface of the protruding piece 211 protruding outward from the main gear 204. After that, the main gear 204 further rotates, and as shown in FIG. 30, the switch piece 21 of the position detecting switch 212.
2a is rotationally pressed by the outer peripheral surface of the protruding piece 211.

The rotation of the main gear 204 depends on the rotation of the main gear 204.
It is performed until the rotation pressing of the switch piece 212a by the projecting piece 211 is released with the rotation of. Protrusion 2
When the rotational pressing of the switch piece 212a by 11 is released, the switch piece 212a is returned to the original position by the elastic return means, and one pulse signal is output from the position detection switch 212. This pulse signal is supplied to the system controller described later.

The system controller outputs a stop signal to the motor 203 of the rotary transport mechanism 201 based on the supply of this pulse signal. The rotation drive of the motor 203 is stopped based on the supply of the stop signal from the system controller. The protrusion 21 in the main gear 204
The switch piece 21 of the position detection switch 212 is provided on the side end surface of 1.
From the time when 2a abuts until the motor 203 stops,
The pin 222b on the outer side plate 126 is shown in FIGS.
As shown in 0, the inside of the guide rail 209 moves relative to the outside plate 126 (and the inside plate 125).
It will be idle.

That is, the loading mechanism unit 3 fixed to the inner plate 125 is stopped in the vertical state. Also, from the initial state, the motor 20
The gear part 227 of the rack member 224 always faces the non-driving portion 208a of the small-diameter gear 208 until the rotation of the rack member 224 is stopped, so that the driving of the small-diameter gear 208 to the rack member 224 is not performed.

Next, when the drive signal is supplied again to the motor 203, and the motor 203 is driven in the reverse rotation, for example, in the opposite direction to the above, the rotary transport mechanism 201 is driven by the rotary transport mechanism 201 shown in FIG.
~ The operation opposite to that shown in Figs. 46 and 60 to 70 is performed. That is, FIG. 46, FIG. 45, and FIG.
And, as shown in FIG. 69, the other pin 222b relatively moves from the guide rail 209 toward the second cam portion 210b. At this time, the outer side plate 126 (and the inner side plate 125) remains stopped. Then, with the reverse rotation of the main gear 204, as shown in FIGS. 44 to 42 and 68 to 66, the pin 222b relatively moves within the rail of the second cam portion 210b.

In this case, since the second cam portion 210b is gradually opened outward with respect to the traveling direction which describes the circumference of the pin 222b which relatively moves the guide rail 209, the main gear is opened. With the reverse rotation of 204, the rail side wall of the cam portion 210b presses the pin 222b toward the front side. That is, the rotational force of the main gear 204 is transmitted to the pin 222b through the cam portion 210b, and the outer side plate 126 (and the inner side plate 125) undergoes an equiangular acceleration motion in accordance with the reverse rotation of the main gear 204, and this driven gear is driven. The gear portion 221 a of the gear 221 is rotated in the direction in which it meshes with the medium-diameter gear 207 of the main gear 204.

Then, the pin 2 formed by the cam portion 210b is used.
The outer plate 126 (and the inner plate 125) reaches the same angular velocity as that of the main gear 204 again by applying the rotational force to 22b. At this time, as shown in FIG. 41, the driven gear 221
The gear portion 221a and the medium diameter gear 207 start to mesh with each other, and the pin 222b is disengaged from the second cam portion 210b.

With the reverse rotation of the main gear 204, this time,
Gear part 221 in medium-diameter gear 207 and driven gear 221
As shown in FIGS. 40 to 37 and FIG. 65, the outer plate 126 (and the inner plate 125) carries out a uniform angular velocity motion as in the main gear 204, so that the pair of pins 222a and Rotation is performed so that 222b is aligned with the vertical line, that is, the loading mechanism unit 3 fixed to the inner plate 125 is horizontal (see FIG. 28).

Further, with the reverse rotation of the main gear 204, as shown in FIGS. 36 and 64, one pin 222a enters into the rail of the first cam portion 210a. Since the first cam portion 210a is gradually closed inward with respect to the traveling direction that describes the circumference of the one pin 222a, this first cam portion 210a is rotated with the reverse rotation of the main gear 204. The rail side wall 210a presses the pin 222a to the depth side.

That is, the rotational force of the main gear 204 is transmitted to the pin 222a through the cam portion 210a, and the outer plate 1
26 (and the inner side plate 125) decelerates with equal angular acceleration in accordance with the reverse rotation of the main gear 204, and the gear portion 221a of the driven gear 221 and the medium-diameter gear 2 of the main gear 204.
It is rotated in the direction to release the mesh with 07.

When the main gear 204 further rotates in the reverse direction, as shown in FIGS. 35 to 33 and 63 to 61, the outer side plate 126 (and the inner side plate 125) is moved to the cam portion 21.
0a rail rotates so that the pin 222a is guided to the guide rail 209 side.
When it reaches within 09, as shown in FIGS. 32 and 60,
It is rotatably transported to the same position as in the initial state. That is, in the loading mechanism unit 3, as shown in FIG. 14, the mounting portion 128 of the disc holder 121 has the recording / reproducing unit 2 mounted thereon.
It will be rotatably conveyed to a position facing.

At this time, the two elongated holes 225a and 225b formed in the inner plate 125 are such that their major axes are along the vertical line, and further, they project from the outer plate 126 and are formed in one of the elongated holes 225a. Pin 22 inserted
6 is located at the lowermost end of the elongated hole 225a. Further, the support shaft 124 inserted into the other elongated hole 225b and the first elongated hole 229a of the rack member 224 is also located at the lowermost end of the other elongated hole 225b and the first elongated hole 229a.

By the way, the main gear 204 is still the motor 2 even if the loading mechanism unit 3 returns to the initial state.
By the rotational drive of 03, further reverse rotation is performed.
With the reverse rotation of the main gear 204, this time, as shown in FIG.
As shown in FIG. 50, the small-diameter gear 2 in the main gear 204
The drive portion 08 (i.e., the portion where gear teeth are arranged circumferentially) 208b is rotationally moved toward the rack member 224.

Then, as shown in FIG. 51, the small diameter gear 2
The end of the driving portion 208b at 08 is the rack member 22.
The fourth gear portion 227 comes into contact with the gear tooth 227a formed at the lowermost end and having a relatively large tooth depth. From this stage, the chucking mechanism 202 is activated. That is,
When the main gear 204 further rotates in the reverse direction, as shown in FIGS. 52 and 53, the driving portion 208b of the small diameter gear 208 is driven.
End presses the gear tooth 227a having a large tooth depth of the rack member 224 downward. Due to this pressing, the rack member 224 moves downward, and accordingly, the inner plate 125 that rotatably supports the rack member 224 via the support shaft 228 resists the bias of the tension coil spring 232. Move down.

When the main gear 204 further rotates in the reverse direction, as shown in FIGS. 54 to 56, the drive portion 208b of the small-diameter gear 208 and the gear portion 227 of the rack member 224 mesh with each other, and the main gear 204 rotates in the reverse direction. As the rack member 224 rotates downward, the inner plate 12
5, that is, the loading mechanism unit 3 moves relatively downward.

By the downward movement of the inner plate 125, the support shaft 124 protruding from the recording / reproducing unit 2 is moved to the first long hole 229a and the second long hole of the rack member 224 as shown in FIG. When reaching the communicating portion of the hole 229b, the switch piece 212a of the position detection switch 212 is again provided on the side end surface of the projecting piece 211 protruding outward from the main gear 204.
Abut. At this point, as shown in FIGS. 16 and 31, the housing 123 of the loading mechanism unit 3 reaches the bottom dead center.

When the main gear 204 further rotates in the reverse direction, FIG.
This time, as shown in FIG.
The support shaft 124 which rotates around 8 and projects from the recording / reproducing unit 2 relatively moves in the second elongated hole 229b toward the end thereof. At this time, the inner side plate 125 is in a stopped state. In addition, as the main gear 204 rotates in the reverse direction, the switch piece 212a of the position detection switch 212 is moved to the main gear 2
The outer peripheral surface of the protruding piece 211 of No. 04 is rotationally pressed.

Then, as shown in FIG. 59, the supporting shaft 1
When 24 reaches the end of the second elongated hole 229b, the protruding piece 2
When the rotational pressing of the switch piece 212a by 11 is released, the switch piece 212a is returned to the original position by the elastic return means, and one pulse signal is output from the position detection switch 212. This pulse signal is supplied to the system controller, and the system controller outputs a stop signal to the motor 203 based on the supply of this pulse signal.

The rotation driving of the motor 203 is stopped based on the supply of the stop signal from the system controller. At this time, the inner plate 125 is in a state in which the support shaft 124 is engaged in the end portion of the second elongated hole 229b of the rack member 224, and thus the inner plate 125 cannot move in the vertical direction. From this, the second elongated hole 228b
Has a function as a lock member for the inner plate 125. In addition, from the initial state until the box 123 of the loading mechanism unit 3 reaches the bottom dead center, one of the pins 222a moves relative to the inside of the guide rail 209, and the outer plate 126 (and the inner plate 125).
Becomes idle.

After that, when the drive signal is supplied again to the motor 203 and the motor 203 is driven to rotate forward again,
The chucking mechanism 202 performs the reverse operation to the above to move the inner plate 125 upward. This movement is performed by the outer plate 1
The pin 226 of 26 and the support shaft 124 are provided with the long holes 2 respectively.
25a and 225b until the uppermost end is reached, at which time the outer plate 126 (and the inner plate 125) is moved to the position shown in FIG.
4 and the initial state shown in FIG. 32 is returned to, and the box 123 of the loading mechanism unit 3 reaches the top dead center (see FIG. 15).

The rotary transport mechanism unit 4 or the loading mechanism unit 3 is provided with a position detection sensor (not shown) and detects that the outer side plate 126 (and the inner side plate 125) has returned to the initial state. , Outputs the detection signal to the system controller. The system controller outputs a stop signal to the motor 203 based on the input of the detection signal from the position detection sensor.
The rotation drive of the motor 203 is stopped based on the supply of the stop signal from the system controller. With this series of operations, the rotary transport operation of the rotary transport mechanism unit 4 with respect to the loading mechanism unit 3 is completed.

Next, the operation when the recording / reproducing apparatus is used as a vending machine for optical disks D will be described with reference to FIGS.
This will be described with reference to FIG. 73 as well.

When this recording / reproducing apparatus is used as a vending machine for optical disks D, a panel plate 241 also serving as a blind is mounted on the front surface thereof, as in a normal vending machine. The panel plate 241 is equipped with an input means composed of various operation buttons such as a power switch and a start button and a display means such as a liquid crystal display for displaying operational messages.

Input data from the input means is supplied to the system controller incorporated in the recording / reproducing apparatus. The system controller controls various drive circuits connected to the system controller in accordance with the input data, and also reads operational message data from the internal data ROM and supplies it to the display means. The display means image-processes the supplied message data and displays the message through the liquid crystal display.

Further, an opening 242 is formed in the panel plate 241 at a position corresponding to the storage unit 1, and the unit main body 11 of the storage unit 1 is located outside the panel plate 241 through the opening 242. Person side). Also, this panel board 241
Has a shutter opening 243 formed at a position facing the insertion / removal opening 122 of the loading mechanism unit 3 supported in a horizontal state, and an opening / closing shutter 244 is attached to the shutter opening 243. The open / close shutter 244 is rotatable frontward (operator side) around a support shaft 245 provided in the lower portion. The opening / closing shutter 244 is biased in a closing direction with respect to the shutter opening 243 of the panel plate by an elastic return means such as a spring.

First, the operator selects the panel plate 241.
Open the opening 2 after operating the power switch
The unit main body 11 is pulled out from the inside of the outer casing 12 of the storage unit 1 through 42. At this time, the contact of the limit switch 51 (see FIG. 4) installed on the depth side of the outer casing 12 is, for example, “OFF”, and a message indicating that the unit main body 11 has been pulled out is displayed on the display means. It After that, the operator sets 25 optical disks D in the unit main body 11 by using the cartridge 55 in which, for example, 25 raw optical disks D shown in FIG. 6 are stored. Since the details of the setting method have already been described, the description thereof will be omitted here.

25 optical disks D are attached to the unit main body 11
After the setting, the operator removes the cartridge 55 from the unit main body 11, and further returns the unit main body 11 into the outer casing 12 of the storage unit 1 through the opening 242. At this time, the contact of the limit switch 51 is turned on, and the system controller electrically recognizes that the unit main body 11 is mounted in the outer casing 12, and enters the key input waiting state. If the contact of the limit switch 51 is not "ON", the interrupt is disabled, and all key input through the input means is disabled.

After that, the operator operates the start button on the panel plate 241. By operating this start button, a start request signal is supplied from the input means to the system controller. The system controller outputs a start signal to the motor 33 in the rotary drive mechanism section 23 of the unit body 11 based on the input of the start request signal from the input means. The motor 33 is rotationally driven based on the supply of the start signal, and the three feed screws 31a, 31b and 31c are driven.
Rotate each. These three feed screws 31a, 3
By the rotation of 1b and 31c, the set 25 optical disks D are sequentially transported to the front side.

Then, as shown in FIG. 71, the leading optical disc D is transported to a position corresponding to the opening 242 formed on the upper surface of the storage unit 1 on the front side, and is installed on the front side of the unit main body 11. Position detection sensor mechanism 73
When the detection signal is output from the position detection sensor mechanism 73, the detection signal from the position detection sensor mechanism 73 is supplied to the system controller 244, and the system controller outputs a stop signal to the motor 33 in the rotary drive mechanism section. Motor 3
The rotation drive of No. 3 is stopped based on the supply of this stop signal, and the operation of conveying the optical disc D by the three feed screws 31a, 31b, and 31c is stopped.

The system controller outputs a forward rotation drive signal to the motor 203 of the rotary transport mechanism 201 in the rotary transport mechanism unit 4 based on the supply of the detection signal. The motor 203 is rotationally driven based on the forward rotation drive signal from the system controller to rotate the main gear 204 forward. With the normal rotation of the main gear 204, as described above, the loading mechanism unit 3 is rotationally conveyed to a position where the insertion / removal opening 122 of the housing 123 and the opening 104 of the storage unit 1 face each other.
The storage unit 1 is upright. At this time, the roller driving means 13 of the loading drive unit 3
3 comes to a position facing the inside of the storage unit 1 through the opening 104 of the storage unit 1 (see FIG. 14).

When the loading mechanism unit 3 is in the upright state, a pulse signal is output from the position detection switch 212 in the rotary transfer mechanism unit 4 and supplied to the system controller. The system controller outputs a stop signal to the motor 203 based on the supply of the pulse signal. The motor 203 is
The rotation drive is stopped based on the supply of the stop signal.

Further, the system controller outputs a start signal to the motor 83 in the delivery mechanism 74 of the storage unit 1 based on the supply of the pulse signal from the position detection switch 212, and also the disc holder 121 of the loading mechanism unit 3. A normal rotation drive signal is output to the motor 156 of the rotation drive mechanism 141 installed at. The motor 83 of the feed mechanism 74 and the motor 156 of the rotary drive mechanism 141 are rotationally driven based on the supply of the start signal and the normal rotary drive signal from the system controller.

The delivery mechanism 74 pushes the top optical disc D upward through the opening 104 as the motor 83 is driven to rotate. Further, the rotation driving mechanism 141 of the disc holder 121 is driven by the motor 156 to rotate normally, and the driving roller 13 in the roller driving means 133 is driven.
5 in the forward direction, that is, the optical disc D is the disc holder 121.
Rotate in the direction to pull in. The optical disc D pushed upward by the delivery mechanism 74 has the drive roller 135 and the two rollers 1 in the roller drive means 133.
It will enter between 34a and 134b.

In this case, the rotation speed of the driving roller 135 is made faster than the pushing speed of the optical disk D by the feeding mechanism 74, so that the optical disk D that has entered between the driving roller 135 and the two rollers 134a and 134b is transferred to the disk holder 121. It can be easily pulled in. The arm 87 of the feeding mechanism 74 moves to the uppermost end as it is even though the optical disc D is pulled into the disc holder 121, and then returns to the original position, that is, the lowermost position again and stops. .

By the pulling operation of the optical disc D into the disc holder 121 by the roller driving means 133, the optical disc D has substantially the circular opening 129 of the mounting portion 128 of the disc holder 121 and the center hole of the optical disc D. When accommodated up to the coincident position, the housed state is detected by a known position detection sensor (not shown), and the detection signal is supplied to the system controller. When the detection signal from the sensor is supplied, the system controller outputs a stop signal to the motor 156 of the rotary drive mechanism 141. The rotation driving of the motor 156 is stopped based on the supply of the stop signal, and the rotation of the driving roller 135 is also stopped. At this time, the optical disc D is held in such a manner that the lower end thereof is sandwiched between the drive roller 135 and the two rollers 134a and 134b.

At the same time, the system controller outputs a reverse rotation drive signal to the motor 203 of the rotary transport mechanism 201 in the rotary transport mechanism unit 4 based on the supply of the detection signal. The motor 203 is rotationally driven based on this reverse rotation drive signal, and this time rotates the main gear 204 in reverse. With the reverse rotation of the main gear 204, as described above, the loading mechanism unit 3 is rotationally conveyed to a position where the mounting portion 128 of the disc holder 121 and the recording / reproducing unit 2 face each other, and the outer plate 126
(And the inner plate 125) is upright, that is, the loading mechanism unit 3 is horizontal.

Further, the main gear 204 is reversely rotated by the rotational drive of the motor 203. With the reverse rotation of the main gear 204, the chucking mechanism 202 of the rotary transfer mechanism unit 4 moves the loading mechanism unit 3 downward. Move to the box 12 of the loading mechanism unit 3
3 descends from top dead center to bottom dead center. During the lowering process of the box 123, the opening 155 of the disc holder 121
The abutting piece 152 protruding downward through the abutment contacts the upper surface of the recording / reproducing unit 2.

At this time, the optical disk D is the turntable 11 of the spindle motor in the recording / reproducing unit 2.
0 is placed on. The box 123 is further moved downward by the driving operation of the chucking mechanism 202 accompanying the rotation of the main gear 204. By the downward movement of the box 123, the contact piece 152 of the roller drive means 133 is lifted upward, and as a result, the drive roller 135 is pushed up, and the drive roller 135 for the optical disc D is driven.
And the nipping by the two rollers 134a and 134b is released.

Further, the pressure regulating plate 153 which is in contact with the upper surface of the peripheral portion of the optical disc D is also lifted upward. In addition, at this time, by moving the inner plate 125 downward,
Since the outer side plate 126 moves relatively upward, the clamp lever 182 in the clamp mechanism 181 is moved.
The elongated hole 194, through which the operating piece 192 is inserted, moves upward relative to the clamp lever 182, and the lower end portion of the elongated hole 194 presses the operating piece 192 upward.

By pushing the operation piece 192 upward, the clamp lever 182 of the clamp mechanism 181 rotates about the support shaft 180, and by so-called leverage,
The clamp plate 185 moves downward and the clamp plate 18
5 and the center pole 195 of the turntable 110 are attracted to each other via the magnet 191. By this suction, the optical disk D is in a form in which the central portion is clamped by the lower surface of the clamp plate 185 and the turntable 110.

As described above, when the box 123 is located at the bottom dead center and the optical disc D is mounted on the turntable 110, a pulse signal is output from the position detection switch 212 in the rotary transport mechanism unit 4, Supplied to the system controller. The system controller outputs a stop signal to the motor 203 based on the supply of the pulse signal. The rotation driving of the motor 203 is stopped based on the supply of the stop signal. Further, the system controller outputs message data based on the supply of the pulse signal from the position detection switch 212 and causes the display means to display a message indicating “ready”.

After confirming that the message "ready" is displayed on the display means, the operator makes a reproduction request to the sound source, and at the same time operates the recording key on the panel plate 241. By operating this recording key, a recording request signal is supplied from the input means to the system controller. The system controller rotates the spindle motor of the recording / reproducing unit 2 based on the input of the recording request signal from the input means, and records the tone signal supplied from the sound source on the optical disc D via the optical head 111.

When the recording of the tone signal by the optical head 111 is completed, the system controller outputs the message data and displays the message indicating "recording completed" through the display means. At the same time, the system controller outputs a forward rotation drive signal to the motor 203 of the rotary transport mechanism 201 in the rotary transport mechanism unit 4. The motor 203 is rotationally driven based on the supply of the forward rotation drive signal to rotate the main gear 204 forward.

With the normal rotation of the main gear 204, the inner side plate 125 moves upward, and the chucking mechanism 202 described above.
The reverse operation to the above is performed. That is, the optical disc D is lifted upward by the mounting portion 128 of the disc holder 121, and in the upward movement process,
The contact plate 152 of the roller driving means 133 gradually protrudes from the corresponding opening 155, and accordingly, the driving roller 135 moves toward the two rollers 134a and 134b to move the circumferential end of the optical disc D to the driving roller. It is sandwiched by 135 and the two rollers 134a and 134b, and the pressure regulating plate 153 of the roller driving means 133 contacts the upper surface of the optical disc D.

Further, the magnetic attraction between the clamp plate 185 and the turntable 110 in the clamp mechanism 181 is released, and the operation piece 192 of the clamp lever 182 is elongated hole 194.
When pressed down at the upper end of the clamp lever 18
Support shaft 1 so that 2 lifts clamp plate 185 upward.
The clamp plate 185 rotates about 80 and the optical disc D
It becomes a form that goes away from above.

When the box 123 of the loading mechanism unit 3 reaches the top dead center, a detection signal is output from a known position detection sensor (not shown) to the system controller. The system controller outputs a stop signal to the motor 203 in the rotary transport mechanism unit 4 based on the supply of the detection signal from the sensor, and the motor 162 of the slide mechanism 161 in the housing 123.
A forward rotation drive signal is output to. Rotary transport mechanism unit 4
The motor 203 stops its rotational drive based on the supply of the stop signal, and the housing 123 of the loading mechanism unit 3 is held at the top dead center.

At this time, as shown in FIG. 71, the insertion / removal opening 122 of the box 123 of the loading mechanism unit 3 is inserted.
Is aligned with the position of the shutter opening 243 of the panel plate 241 on the horizontal line. On the other hand, the motor 162 of the slide mechanism 161 horizontally conveys the disc holder 121 to the front side through the insertion / removal opening 122 based on the supply of the forward rotation drive signal.

As the disc holder 121 is horizontally conveyed by the slide mechanism 161, the disc holder 121 is moved.
As shown in FIG. 72, the roller driving means 133 presses the opening / closing shutter 244 toward the front side, and resists the urging by the elastic return means (not shown) to open / close the shutter 24.
4 is rotated in the opening direction. And the slide mechanism 1
The position detection switch 177, which is engaged with the gear 166 of the No. 61 via the operation plate 170, rotationally moves to the front side as the gear 166 rotates, and the internal contact is, for example, “on”.
Then, the switch 177 outputs an ON signal.

The system controller is the switch 1 described above.
Based on the ON signal from 77, a stop signal is output to the motor 162 of the slide mechanism 161. The motor 162 is
The rotation drive is stopped based on the supply of this stop signal,
The horizontal conveyance of the disc holder 121 is stopped. Further, the system controller outputs a reverse rotation drive signal to the motor 156 of the roller drive means 133 based on the supply of the ON signal. The motor 156 is rotationally driven based on this reverse rotation drive signal to rotate the drive roller 135 in reverse.

With the reverse rotation of the drive roller 135,
As shown in FIG. 73, the optical disc D has a disc holder 1
21 and is exposed from the shutter opening 243. When the drive roller 135 is rotationally driven by the motor 156, the center hole of the optical disc D is moved to the shutter opening 24.
It is performed from 3 to exposure. The exposure amount of the optical disc D from the shutter opening 243 can be easily detected by a known sensor (not shown) provided on the disc holder 121 or the panel plate 241.

Then, the operator operates the shutter opening 243.
The optical disc D exposed from the above is removed. In this case, the center hole of the optical disc D is the shutter opening 24.
Since it is exposed from No. 3, the extraction is very easy, and the inconvenience of having to hold the recording surface of the optical disk D by hand is avoided. The removal of the optical disc D can be detected by, for example, the above-mentioned known sensor that detects the exposure amount of the optical disc D.

When a signal indicating that the optical disc D has been ejected is supplied from this sensor to the system controller, the system controller outputs a forward rotation drive signal to the motor 162 of the slide mechanism 161. The motor 162 is rotationally driven based on the supply of the forward rotation drive signal. The slide mechanism 161 inserts and removes the disk holder 121 into and out of the disk holder 121 by the rotational driving of the motor 162.
The disk holder 121 is conveyed horizontally in the direction of the inside of the box 123, and finally the disk holder 121 is housed in the box 123.

With the above series of operations, the operation of the optical disk D as a vending machine is completed. The storage unit 1
When recording on the next optical disc D housed in the optical disc D, the start button on the panel plate 241 is operated again to re-execute the series of operations described above, and a musical tone signal is recorded on the optical disc D. It will be.

As described above, in the recording / reproducing apparatus according to the present embodiment, the loading mechanism unit 3 for temporarily accommodating the optical disc D has the accommodating position and the optical disc D mounting portion (turn) of the spindle motor of the recording / reproducing unit 2. The position where the table 110) faces each other,
Since it is only rotationally conveyed between the position rotated by 90 ° from that position, the range of movement is very small. Therefore, it is possible to effectively reduce the size of the entire structure.

Particularly, the optical disc D is loaded into the roller driving means 13
Since it can be inserted into and removed from the accommodation position of the loading mechanism unit 3 at 3, the optical disc D at a predetermined position of the accommodation unit 1 can be easily attached to the accommodation position of the loading mechanism unit 3, for example. The optical disc D on which the information signal has been recorded can be sent out of the loading mechanism unit 3 from its storage position.

Therefore, the loading mechanism unit 3 is
The storage position is the turntable 1 of the recording / reproducing unit 2.
When the optical disc D is sent outward by the roller driving means 133 in a position facing each other with the optical disc D, the optical disc D can be sent out through a path different from the storage unit 1 side. It becomes possible to have a function as a vending machine.

Then, the roller driving means 133 is set to 2
By comprising the book rollers 134a and 134b and the drive roller 135 provided above the center of the two rollers 134a and 134b in the arrangement direction,
The optical disk D can be taken in and out in a stable state with respect to the accommodation position.

Further, the optical disc D accommodated in the accommodating position of the loading mechanism unit 3 can be easily mounted on the turntable 110 of the recording / reproducing unit 2. Moreover, since the chucking mechanism 202 is provided on the rotary transport mechanism unit 4 itself, the loading mechanism unit 3 is moved relative to the turntable 110 in association with the rotary transport of the loading mechanism unit 3 by the rotary transport mechanism unit 4. It is possible to move in the contact and separation directions.

In the vending machine for the optical disc D using the recording / reproducing apparatus according to the above-mentioned embodiment, after recording the tone signal supplied from the sound source on the optical disc D, the optical disc D is recorded.
Is transmitted by the slide mechanism 161 and the roller driving means 133 through the insertion / ejection opening 122 of the loading mechanism unit 3. Alternatively, after recording the musical tone signal, for example, by operating the reproduction key on the panel plate 241, the optical The tone signal recorded on the optical disc D is reproduced through the head 111, and then the optical disc D is reproduced.
May be sent out through the insertion / removal opening 122 of the loading mechanism unit 3.
