ABSTRACT:
TECHNICAL FIELD
The present invention relates to a recording and/or playback apparatus of a disklike recording medium. In particular, it relates to a recording and/or playback apparatus for taking one disklike recording medium out of a plurality of disklike recording media and then conducting a playback of information signals, such as musical sound signals and the like, recorded on the taken-out disklike recording medium or for conducing a recording of information signals, such as musical sound signals and the like, on a disklike recording medium
BACKGROUND TECHNIQUE
A recording and/or playback apparatus using a disklike optical recording medium (hereinafter simply optical disk), which is shown in
FIG. 1
, is known.
A recording and/or playback apparatus
1
is equipped with a disk receiving portion
2
, in which a large number of optical disk supporting portions
22
. . .
22
are arranged, and one end portion of an optical disk
201
is one-side supported on these supporting portions
22
. . .
22
, a loading portion
6
for taking out the optical disk
201
in the supporting portion of a desired address in first to nth addresses of the optical disk receiving portion
2
, a conveyance mechanism
3
for adjusting the optical disk
201
in the supporting portion of a desired address to the position of the loading portion
6
, a locking mechanism
4
for locking the position of the optical disk receiving portion
2
and the loading mechanism
6
, which have been aligned, and a recording and/or playback portion
8
for conducing a recording and/or playback of the optical disk
201
loaded by the loading mechanism
6
.
The optical disk receiving portion
2
is provided with the optical disk supporting portions
22
. . .
22
in the form of groove in a radial direction of an upper surface of a rotating table
21
that rotates about a shaft
23
. Lower end portions of optical disks
201
are brought into engagement with the optical disk supporting portions
22
. . .
22
in the form of groove. With this, these optical disks
201
. . .
201
are one-side supported by the rotating table
21
under a condition that they are stood substantially upright. The rotating table
21
is driven to rotate by the conveyance mechanism
3
, and thereby the optical disk
201
of a desired address is moved to the position of the loading mechanism
6
.
The loading mechanism
6
is arranged outside of the rotating table
21
, takes it out of the supporting portion
22
in the form of groove by clamping, with a pair of arms, a periphery of the optical disk
201
of a desired address out of the first to nth addresses of the rotating table
21
locked by the locking mechanism
4
, and moves the optical disk
201
to the loading position at which it is subjected to a chucking at the recording and/or playback portion
8
.
The conveyance mechanism
3
is equipped with a gear
41
meshing with gear teeth
31
. . .
31
formed on an peripheral portion of the rotating table
21
, and the rotating table
21
is driven by rotating the gear
41
with a motor
44
.
The locking mechanism
4
has a table engaging portion
51
, which engages with the gear teeth
31
. . .
31
formed on the peripheral portion of the rotating table
21
, and locks the rotating table
21
unrotatably by bringing the table engaging portion
51
into engagement with the gear teeth
31
. . .
31
.
The recording and/or playback portion
8
is equipped with a first flame portion
143
for rotation/signal detection, which is equipped with a disk table
141
, an optical pickup device
142
and the like, and a second frame portion
145
for chucking, which is equipped with a damper
144
. When the optical disk
201
of a desired address is moved to a loading end position by the loading mechanism
6
, the first frame portion
143
and the second frame portion
145
get closer to each other. With this, the damper
144
is magnetically attracted to the side of the disk table
141
, and the optical disk
201
clamped by the loading mechanism
6
is subjected to a chucking on the disk table
141
by the damper
144
.
By the way, according to the above-mentioned recording and/or playback apparatus shown in
FIG. 1
, in case that the optical disk supported at a desired address of the optical disk supporting portions
22
. . .
22
is broken, there is a problem that it is cumbersome to replace the broken optical disk with a new optical disk. In particular, there is a tendency that the number of the optical disks
201
supported on the rotating table
21
of the optical disk receiving portion
2
increases, for example, a few, then dozens, then a hundred, then two hundreds, and then three hundreds. As its number increases, the optical disks
201
. . .
201
are in a condition in which they are densely overlapped. Thus, there has been a problem that it is difficult to pick out a desired optical disk with one's fingertips or the like.
The present invention is capable of solving the above-mentioned conventional problems and of assuredly and easily taking out a disklike recording medium of a desired address.
DISCLOSURE OF THE INVENTION
A recording and/or playback apparatus of a dislike recording medium of the present invention comprises:
a receiving portion in which a plurality of supporting portions supporting respective peripheral ends of a plurality of disklike recording media are formed in an annular form and in which an opening portion (a cutout
174
in the specification) is formed on the supporting portion;
a recording and/or playback means for conducting recording and/or playback of the disklike recording media;
an ejecting operation means (an ejecting mechanism in the specification) that penetrates from the opening portion of the receiving portion and ejects a desired disklike recording medium out of the disklike recording media, from the supporting portion;
a loading means (a loading mechanism in the specification) that takes out the desired disklike recording medium, which has been ejected from the supporting portion by the ejecting operation means, from the receiving portion and loads the desired disklike recording medium onto the recording and/or playback means; and
a positioning means (a conveyance means in the specification) that rotates the receiving portion and makes the desired disklike recording medium and the loading means oppose to each other.
The ejecting operation means comprises an ejecting lever that moves between a position, at which it projects into the supporting portion through the opening portion, and a position, at which it is separated from the receiving portion, and moves to the projecting position, thereby ejecting the disklike recording medium supported on the supporting portion.
The ejecting lever is formed on its one end side with a projection portion that goes into the supporting portion through the opening portion, and the ejecting lever is formed to be rotatable between the projecting position and the separated position.
The ejecting operation means comprises an operation mechanism that operates the ejecting lever to rotate between the projecting position and the separated position.
The operation mechanism comprises an operating slider (a sliding lever
196
in the specification) that operates the ejecting lever to rotate between the projecting position and the separated position, and a driving mechanism (a sliding lever driving mechanism
197
in the specification) of the operating slider.
The ejecting operation means is arranged on a lower surface side of the receiving portion.
The loading means comprises a holding portion (loading levers
92
,
93
in the specification) that holds the desired disklike recording medium ejected from the supporting portion by the ejecting operation means and that conveys the held, desired disklike recording medium to the recording and/or playback means.
The holding portion is formed to be rotatable between a first position for holding the desired disklike recording medium ejected from the supporting portion by the ejecting operation means and a second position for conv
