Figure 8 is a plan view of an optical disc player 100 which uses has an intermediate packaging device. The turntable 1oo is shown with the cover removed to reveal the one underneath Make details visible. Figures 9 and 10 are sectional views of the video disk player according to Figure 8 along the Center line of this, with a dust protection flap 1o2 in a closed or an open position is arranged.

The video disk player 1oo has an impurity-free

5o

Chamber 1o4, into which the plate packaging through an insertion slot 1o6 is inserted. The insertion slot 1o6 has dimensions which allow the plate packaging 5o can pass through unhindered. The dust cover 1o2 is pivotably attached to the turntable housing 1o8 for movement between the closed position preventing access to chamber 1o4 (FIG. 9) and that allowing access to chamber 1o4 Open position (Figure 1o). The dust protection flap 1o2 is used to prevent contamination of the chamber 1o4 with dust or other foreign matter.

The turntable housing 1o8 is provided with a pair of channels 11o and 112 for guidance when inserting the disc package 5o into the disc player 1oo and when removing it therefrom. The channels 11o, 112 are arranged at an angle relative to the turntable housing 1o8 such that they are with the insertion slot 1o6 align at the front end of the turntable 1oo.

The optical disc player 1oo also has a turntable 114 for rotatably supporting an optical disc during playback on. The turntable 114 has a central mandrel 116, which

-11- 909807/0953

rn

can be received in the centering opening of the image plate. A scanning arm support, which carries a signal pickup device is not shown in the drawing for the sake of clarity. The scanning arm support conveys the signal pickup device across an optical disk arranged on the turntable 114 during playback.

A platform 118 is pivotally mounted about a rod I2o for a movement between a depressed position (Figure 9) and a raised position (Figure 1o). The platform 114 includes a pair of side rails 122 and 124 which are interconnected by a cross member 126 at the rear end of the optical disc player 1oo are connected.

As shown in Figs. 8, 11 and 12, there is a disk pull-out mechanism 128, which is a pair of around bolts 134 and 136 Pivotably arranged latch arms 13o and 132, attached to the rear end of the turntable 1oo on the transverse part 126. As can be seen from Figure 1o, the pawl arms 13o, 132 are aligned with the center line of the channels Ho and 112 when the platform 118 is currently in the raised position. The pawl arms 130, 132 are inserted into the disc holder 54 provided Opening 72 let in when packing the plate 5o is fully inserted into the turntable I00.

The disk pull-out mechanism 128 has a paddle-like lever 138 which is mounted around a cross member 126 Bolt I4o is pivoted. The paddle-like lever 138 is rotated clockwise over an arcuate area when the panel is wrapped 50 is completely inserted into the turntable I00. The clockwise rotation of the paddle-like lever 138 causes that a ratchet gear 142 which is rotatably attached to the cross member 126 is, also advances clockwise by one tooth, which is achieved via a bolt 144 attached to the paddle-like lever 138

-12-909807 / 0953

he follows. Such rotation of the ratchet gear 142 causes that a square cam 146 between the latch arms 13o and 132 is attached and attached to the ratchet gear 142 to a Step (for example 45 °) advances clockwise. A such advancement of the square cam 146 causes the pawl arms 13o and 132 between an extended condition (Figure 12) and a retracted state (Figure 11). A spring 148 connects the rear ends of the pawl arms 130 and 132 to ensure constant engagement between them and the square cam 146 to ensure.

When the disk package 5o is withdrawn from the optical disk player I00 a spring 150 causes the paddle-like lever 138 to return to its position according to FIGS. The disk pull-out mechanism 128 has a pawl 152 for preventing reverse movement of the pawl gear 142 when the paddle-like lever I38 returns to its rest position. From Figures 8, 11 and 12 it can be seen that although the pawl 152 moves the pawl gear 142 in the reverse direction (counterclockwise) direction prevents pawl 152 from moving forward (clockwise) of the pawl gear allows. The bolt 144 is made retractable to allow the paddle-like lever 138 to return to its rest position, without the need to see ratchet 142 in rotates in the opposite direction.

Thus, every time the disk package 50 is in the disk player I00 is fully inserted, the state of the latch arms 130 and 132 between the extended state (Figure 12) and the retracted state (Figure 11) changed. The functioning of the plate pull-out mechanism is described in the German patent application P 27 56 843.0 "From a package operated disc pull-out mechanism for an optical disc player" by the same applicant (Agent file: ROA 71 435) disclosed. This way of working is explained in detail below.

The turntable 100 further includes a platform lever gear assembly 154 for causing the platform to move 114 between the depressed position (Figure 9) and the raised position Position (Figure 1o) depending on the movement of the dust protection flap 1o2 between the denied entry Position (Figure 9) and the position allowing access (Figure 1o). The platform lever gear assembly 154- includes a pair of levers 156 and 158 attached to the dust cover 1o2 for rotation therewith. the Platform lever gear assembly 154 further includes a pair of Springs 16o and 162 which connect the free ends of levers 156 and 158 and side rails 122 and 124 to one another. A pair of stop bolts 164 and 166 are on the turntable body 108 attached to ensure that the platform 118 is raised to a proper height when the dust cover 1o2 is opened, as a result of the insertion of the disk package 5o into the record player 1oo in the manner shown in FIG. 1o. The springs 16o and 162 allow the dust cover 1o2 to override when the disk package 5o is in the disk player 1oo is completely inserted, so that the platform 118 to rises to the exact height without the need for precision parts.

A set of spring loaded lift blocks 168-174 are pivotally attached to side rails 122 and 124 for a subsequent stated purpose. A set of wire springs (176 and 178, for example) are provided for tensioning the lifting blocks (e.g. 172 and 174) towards a raised position as shown in Figures 9 and 10. A set of bolts, (e.g. 18o and 182) is attached to the side rails (e.g. 124) for receipt in openings (e.g. and 186) provided in the lifting blocks (e.g. 172 and 174) such that the upper surfaces of the lifting blocks relative to the platform 118 are arranged exactly (Figures 9 and 1o).

-14- 909807/0953

A part 188 (Figure 8) connects the rear lifting blocks 17ο and 172.

The mode of operation of the turntable 100 is described below with reference to FIGS. 9 to 12. When the plate packaging 5o, which carries an image plate 58, through the insertion slot 1o6 is inserted into the turntable 1oo, it lifts the dust cover 1o2, causing the platform 118 moves up into the position shown in FIG. 1o. The insertion of the record packaging 5o into the record player 1oo causes that the lifting blocks 168-714 extend to the perimeter of the platform 118 retract, allowing the disk package 5o arrives in a fully inserted position in the turntable 1oo. When the plate packaging 5o in the fully inserted Position in the turntable 1oo arrives, the latch arms 13o step and 132 into opening 72 of disk holder 54 (Figure 11).

The arrival of the panel package 50 in the fully inserted position in the turntable I00 causes the latch arms 130 and 132 from the retracted state (Figure 11) to the extended Change state (Figure 12), whereby the plate holder 54 on the platform 118 is locked. If the casing 52 then is withdrawn, on the one hand the latch arms 130 and 132 hold the disc holder 54 carrying the image disc 58 back in the turntable I00, and on the other hand the wire springs work 176 and 178 that the lifting blocks 168 to 174 in the desired return to the raised position. Thus, the disc holder 54 and the optical disc 58 are retained in the turntable I00, being on the lifting blocks 168-174 at a suitable height (i.e. at which their centerlines with the centerline of the channels 146 and 148 are aligned) rest upon completion of the retraction of the casing 52.

In addition, the withdrawal of the casing 52 from the panel

909807/0953

player 1oo that the dust protection flap 1o2 sicli to the one entrance refusing position according to FIG. 9 ″. Such a movement of the dust protection flap 1o2 causes the platform 118 moves to the depressed position of Figure 9, thereby transferring the image plate 58 from the lifting blocks 168 to 174- brought about to the turntable 114- for the playback process will.

If an empty casing 52 in the turntable 1oo through the

/ β-inffef üß * t is Insertion slot 1o6 (Figure 1oX wxrd "the dust protection flap 1o2 opened causing the platform 118 to rise to the raised position (Figure 10). When platform 118 goes up, raise the lift blocks 168-174 · the plate mount 54- and together with this the image plate 58.

When the platform 118 reaches the raised position (Figure 1o), support the lifting blocks 168-174- the plate bracket 54- and the image plate 58 from such that their center line is aligned with the center line of the empty casing 52, which causes the Disk holder 54 and image disk 58 into casing 52 return while inserting. The alignment direction is Subject of the German patent application P 27 56 842.9 "Platten-Abstütz-und Alignment device for an optical disc player "(Representative file: RCA 71 379) by the same applicant.

When the casing 52 is fully inserted into the turntable 1oo it causes the pawl arms 13o and 132 from the extended state (Figure 12) to the retracted state (Figure 11) change, releasing the plate holder 54-. When the casing 52 is removed from the turntable 1oo, the effect Latches (e.g. 84- and 86 of Figure 7) that the enclosed disk holder 54- and the video disk 58 the turntable 1oo leave.

The device described above thus enables a

909807/0953

2B33882

Optical disk 58 can be inserted into the record player 100 and removed from it without direct handling of the optical disk 58 by the user. A plate handling device of this type is described in German patent application P 27 56 841.8 "Optical disk handling device for an optical disk player" by the same applicant (representative files: EGA 71 337) described.

For example, to play the first side of the optical disc 58, the record packaging is 5 ° in the turntable 1oo in such a way inserted that the side of the spine-like part with the display device "side 1" is directed towards the user. if the casing 52 after it has been fully inserted into the turntable 1oo is withdrawn, the plate 58 and the Record holder 54- causes it to remain in the record player 1oo. The depression of the platform 118 results in the optical disc 58 being laid down on the turntable 11A- with its first side is opposite to the playback stylus. When an empty casing 52 is inserted into the turntable 1oo after playback is, the platform 118 raises the optical disc 58 as well as the disc holder 54 so that their return to the enclosure 52 is effected. Since the orientation of the image plate 58 remains constant relative to the backbone-like part 6o and there on spine-like part 6o the identification of the plate side is attached, the identification of the plate side does not depend on the orientation of the casing 52 relative to the backbone-like part 6o.
