The details of the structure in which the disk mounting base 160 is raised or lowered in conjunction with the movement of the slider 153 will be described later. For example, when the left lid 120 and the right lid 130 are opened, the lids 120 and 130 are opened. After it is opened (that is, moved to the left and right ends), the gear 194 meshes with the rack portion 153c of the slider 153 to move the slider 153 and raise the disk mounting table 160. When the gear 194 does not mesh with the rack portion 153c of the slider 153, the slider 1
The pin 153d provided on 53 is used for the cam groove 1 in the gear 194.
It is designed to enter 94a.

Here, the structure of the disk mounting base 160 will be described. As shown in FIGS. 5 and 6, the disk mounting base 160 has a substantially circular shape slightly larger than the diameter of the mounted disk and is driven. A unit placement cutout 161 is provided, and the disk drive unit 170 is placed in the cutout 161. The disc drive unit 170 has a chucking portion 171 and an optical pickup 172, and in a state where the center portion of the disc is chucked by the chucking 171, the drive unit 17
The optical pickup 172 reproduces the data recorded on the disk (or records on the disk) while the spindle motor in 0 drives the disk to rotate. The front side of the disk mounting table 160 is an upright flat surface portion 164.
Two legs 165 and 166 are provided on the lower side thereof.
Further, the wall portion 1 is provided behind the upper surface of the disk mounting table 160.
62 and 163 are projected to prevent a disc that is not properly chucked from falling rearward in the device when the disc mounting table described later is tilted.

Next, the structure in which the rotation of the motor 190 is transmitted to the levers 151 and 152 and the slider 153 when the lid is opened and closed will be described with reference to FIGS. Figure 8,
9 and 10 show the left lid 12 shown in FIGS. 4, 5 and 6.
6 is a diagram showing the states of the sliders 151 and 152 and the lever 153 corresponding to the positions of 0, the right lid 130 and the disk mounting table 160. FIG.

First, when the left lid 120 and the right lid 130 are closed, the state shown in FIG. 8 is obtained. In this state, the gear 195 is the rack portion 15 of the lever 151, 152.
1a and 152a are not meshed with each other, and the lever 151 and the cam groove 195a inside the gear 195 are provided in the two cam grooves 195a and 195b.
The pins 151b and 152b of 152 are in a fitted state.

When the lid is opened from the state shown in FIG. 8, the rotation shaft of the motor 190 is rotated in the rotation direction θ ₁ . The rotation of the motor 190 in this direction causes the gear 195 to rotate, but the cam groove 195a in the gear 195,
As long as the pins 151b, 152b are fitted in the 195b, the cam grooves 195a, 195b and the pins 151b, 152
b only changes the relative positional relationship with b.
Is in an idle state, the positions of the levers 151 and 152 do not change, and the left lid 120 and the right lid 130 remain closed. Then, the rotation of the gear 195 progresses, and the gear 1
From the outlets of the cam grooves 195a and 195b in the pin 95 to the pin 15
When the 1b and 152b are discharged to the outside, the lever 15
1, 152 is slightly moved, the gear 195 is the lever 151,
The rack portions 151a and 152a of the gear 152 are engaged with each other.

By engaging the gear with the rack,
After that, the rotation of the gear 195 is the same as that of the levers 151, 15
2, the levers 151 and 152 linearly move in mutually opposite directions. Therefore, each lever 15
The left lid 120 and the right lid 130 connected to 1, 152 also move linearly in opposite directions to each other,
The right lid 130 is opened.

FIG. 9 is a diagram showing a state immediately after being driven in such an open state (corresponding perspective view is FIG. 5). When the left lid 120 and the right lid 130 are completely opened. , The gear 195 is the rack portion 151a of the lever 151, 152,
Although it does not mesh with 152a, at this time, even if the pins 151c and 152c different from those in the closed state enter the cam grooves 195a and 195b in the gear 195, and thereafter the gear 195 rotates in the same direction, the gear 195 does not rotate. Does not rotate, the positions of the levers 151 and 152 do not change.

By the way, from the state shown in FIG. 8 to the state shown in FIG. 9, the levers 151 and 152 (and the left lid 12
0, the right lid 130) is linearly moving from the closed state to the open state, the gear 194 in the preceding stage of the gear 195 is not meshed with the rack portion 153c of the slider 153,
The pin 153d provided on the slider 153 enters the cam groove 194a in the gear 194, and the cam groove 194 is formed.
Only the relative positional relationship between a and the pin 153d changes, and the position of the slider 153 does not change.

Here, as shown in FIG. 9, the lever 151,
When 152 is in the open position, the pin 153d of the slider 153 comes to be positioned at the outlet of the cam groove 194a in the gear 194, the slider 153 moves slightly, and the gear 194 meshes with the rack portion 153c of the slider 153. Like Therefore, if the motor 190 continues to be driven in the same direction in this state, the slider 153 moves linearly in association with the rotation of the gear 194.

As the slider 153 linearly moves a certain distance in this way, the disk mounting table 160 connected to the slider 153 rises. FIG. 10 shows the position of the slider 153 when the disc mounting table 160 is raised, and FIG. 6 is a diagram itself showing the state where the disc mounting table 160 is raised.

In the above description, the left lid 120 and the right lid 1
Although the state when the lid 30 is opened has been described, when the lid is closed, the levers 151 and 152 and the slider 153 are rotated by rotating the motor 190 in the opposite direction.
Moves in the opposite direction, and from the state shown in FIGS. 6 and 10,
The left lid 120 and the right lid 130 shown in FIGS. 4 and 8 are changed to the closed state. It should be noted that some kind of sensor or switch is provided for detecting that the left lid 120 and the right lid 130 are in the completely open position or the completely closed position. It may be configured to stop the rotation of 190.

Next, the slider 15 shown in FIGS.
A state in which the disk mounting table 160 is raised by the linear movement of No. 3 will be described with reference to FIGS. 11 to 14. Figure 1
1, FIG. 12 shows a slider 153 and a disk mounting table 160.
13 and 14 are views seen from the front side, and FIGS. 11 and 13 show a state in which the disk mounting table 160 is lowered, and FIG. 12 and FIG. FIG. 14 shows a state in which the disc mounting table 160 is raised.

As shown in FIGS. 11 and 12, the slider 1
When 53 is viewed from the side, two grooves 153a and 153b are formed, and each groove 153a and 153b is
It is tilted at an angle. In each groove 153a, 153b,
Pins 165a and 166a extending in the horizontal direction are fitted from leg portions 165 and 166 on the lower side of the disk mounting base 160. The pins 165a and 166a are provided with slanted grooves 153.
When it is located at the lowest portion of a and 153b, the disk mounting table 160 is in a lowered state. Pin 165a,
When the 166a is located at the highest position in the slanted grooves 153a and 153b, the disc mounting table 160 is in a raised state.

Therefore, the rotation of the gear 194 causes the slider 15 to move.
3 moves horizontally and the pin 1 in the grooves 153a and 153b
By changing the positions of 65a and 166a, the disk mounting table 160 moves up and down. Ascending and descending here are, as shown in FIGS. 13 and 14, the ascending operation and the descending operation due to the inclination around the rotation shaft 167. That is, the disc mounting table 160 on which the disc 99 is mounted has a support portion 15 provided on the rear side of the frame member 140 on the rear side.
4, a rotation shaft 167 is supported, and a pin 165a provided on the leg portions 165 and 166 (the right leg portion 166 is not shown in FIGS. 13 and 14) in front of the disc mounting table 160. , 166a into grooves 153a, 153
It is configured to be supported by b. Here, in order to cope with the change in the angle formed by the pins 165a, 166a and the grooves 153a, 153b due to the inclination of the disk mounting table 160, the tips of the pins 165a, 166a are shown in FIGS.
As shown in FIG.

With such a mechanism, in the lowered state, as shown in FIG.
When 0 is arranged in a substantially horizontal state, the lid is opened, and the disk mounting table 160 is raised, the disk tilts about the rotation shaft 167. By inclining in this manner, the front of the disc mounting table 160 is located in front of the reproducing apparatus 100, as shown in FIG.
The disc 99 placed on the disc mounting table 160 is located above the through hole 101 of
The front side projects above the through hole 101.

Since the vertical movement of the disc mounting table 160 is performed when the left and right lids are opened and closed, it is possible to favorably exchange the discs. That is, the left lid 12
0 and the opening operation of the right lid 130, the internal drive mechanism is shown in FIG.
During the movement from the state shown in FIG. 10 to the state shown in FIG. 10, the disk mounting base 160 is interlocked with the movement of the slider 153, from the horizontal state shown in FIG. 11 and FIG.
The disc mounting table 160 and the disk mounted on the mounting table 160 change to the raised state (inclined state) shown in FIG. Therefore, even if the size of the through hole 101 is almost equal to the diameter of the disc (for example, a diameter larger than the diameter of the disc by a few mm), the user can set the disc mounting table 16
It is possible to easily perform a replacement work for taking out a disk chucked by the chucking portion 171 on the upper side of the disk 0 and chucking another disk.

When the lid is simply opened and closed as in a conventional reproducing apparatus, it is necessary to put a hand into the through hole 101, and in order to secure a space for a finger holding a disc to enter. It is necessary to make the size of the through hole 101 several cm larger than the diameter of the disc, so that the size of the disc mounting portion of the disc reproducing device viewed from the outside can be reduced. Regarding the size of the playback device itself (that is, the size of the housing constituting the device), the left and right lids 120, 130
In order to secure a space for the lid to be accommodated on the left and right when the door is opened, it is necessary to have a size substantially equal to that of the conventional case, but since the through hole 101 may have a small diameter, the through hole 10 is relatively open.
The area of the upper surface of the casing on the left and right sides of 1 is widened, and it can be effectively utilized as a space for arranging the operation keys 102 and the like as in the example shown in FIG.

Further, as in the example shown in FIG. 1, in the case of a reproducing apparatus in which the speakers 103 and 104 are housed on the left and right sides of the housing, there is a margin in the left and right longitudinal directions of the housing. Therefore, as in this example, it is relatively easy in structure to secure a space in which the lid is housed on the left and right, and this is suitable for this type of reproducing apparatus.

Further, in the case of this example, the left and right lids 120, 1
Opening and closing 30 and raising and lowering the disk mounting table 160
Since it is realized by driving with one motor 190, the drive mechanism section can have a simple structure.

In the structure described so far, the lid is divided into two parts, a left lid and a right lid, which is a so-called double-opening structure that opens to the left and right. However, only one lid is provided and one lid is used. The disk mounting table may be raised or lowered in conjunction with the movement in the substantially horizontal direction.

Further, in the above-mentioned embodiment, the disk mounting table is raised and lowered, the front end is moved up and down by inclining the disk supported by the shaft supported by the shaft member. Instead of inclining the disk mounting table, the disk mounting table may be vertically moved up and down.

Further, the shape and mechanism of each member such as the disk mounting table, the lever, and the slider described in the above-mentioned embodiments are merely examples, and other mechanisms and members realize similar functions. It may be done.

Furthermore, in the above-described embodiment, an example in which the present invention is applied to a disc reproducing apparatus for audio reproduction has been described, but the constitution of the present invention can be applied to other disc reproducing apparatuses and disc recording apparatuses. Of course.

According to the present invention, the cover member is positioned at the through hole portion of the housing, so that the through hole is covered and the disk mounting table is covered. Then, as the lid member moves in parallel in the lateral direction, the disk mounting table disposed below the through hole is exposed. At this time, the disc mounting table is raised to the through hole side in conjunction with the parallel movement of the lid member, so that the disc mounted on the disc mounting table can be easily taken out.

Further, in the above case, the lid member is divided into at least the first member and the second member, and when the lid member is driven by the driving means and is separated from the through hole, the lid member and the first member are separated from each other. By parallel moving the two members so as to move in mutually different directions, it is possible to form a so-called left-right double-opening structure with the two lid members. For example, by providing a through hole in the center of the upper surface of the housing, The position of the lid member in the opened state can be made bilaterally symmetric, and the layout can be excellent in terms of design, and the housing constituting the disk drive device can be downsized.

Further, when the disc mounting table is lifted by the driving means, the disc holding surface is tilted by the rotation about a predetermined fulcrum, and a part of the disc mounting table distant from the fulcrum is raised. Then, it is possible to raise the disk mounting table with a relatively simple structure in which the disk mounting table is inclined.

Further, when the disc mounting table is raised in this way, the rise causes a part of the disc held by the disc holding means to project from the through hole to the outside of the housing. When the disc is removed, by holding the portion protruding outward from the housing, the disc can be easily removed, and the disc can be easily replaced without putting a hand inside the through hole.
