ABSTRACT:
TECHNICAL FIELD
The present invention relates to a disk device and more particularly to a disk device which permits plurality of disks to be operated selectively without using a removable magazine.
BACKGROUND ART
FIG. 172
is a sectional side view of a conventional disk device which permits plurality of disks to be operated selectively and
FIG. 173
is a sectional view of a principal portion thereof.
In
FIGS. 172 and 173
, the reference numeral
1
denotes a magazine in which disks for replacement are stored and
2
denotes a disk rotation driving section. The disk rotation driving section
2
is made up of a disk rotating motor
3
, a disk clamping hub
13
mounted on a shaft of the motor
3
, a disk damper
4
, a disk roller
6
for sending out a disk
8
delivered by an actuating lever
5
to the disk rotation driving section
2
, the actuating lever
5
being mounted within the magazine
1
and driven by a driving means (not shown), a drive shaft
9
fixed to a housing
7
which supports the disk rotation driving section
2
, a swash plate cam
10
which is:operated in the directions of A in
FIG. 172
by the driving means, and upper and lower guide plates
11
.
In this conventional disk device, when calling any one of plurality of disks stored in the magazine
1
, the drive shaft
9
, the swash plate cam
10
, and the upper and lower guide plates
11
are interlocked with one another, causing the disk rotation driving section
2
to move in an arrow B direction and allowing it to be located at a desired disk position within the magazine
1
.
In such a conventional disk device, the disks stored in the magazine
1
and the disk rotating on the disk rotation driving section
2
are completely independent of each other in a plane area, thus it gives a rise to the problem that the length, i.e., size D, of the disk device increases.
In order to solve the aforementioned problem, there has been proposed, for example, such a disk device as is disclosed in Japanese Laid Open Patent Sho 63-200354(1988).
FIGS. 174 and 175
are sectional side views of a principal portion of this disk device and
FIG. 176
is a sectional top view thereof.
In
FIGS. 174
,
175
, and
176
, reference numeral
19
denotes a magazine in which disks for replacement are stored,
21
denotes a disk rotating motor,
22
denotes a disk clamping hub mounted on a shaft of the motor
21
, and
23
denotes a disk clamper.
Reference numeral
26
denotes a disk roller for sending out a disk
25
delivered by an actuating lever
24
to a disk rotation driving section, the actuating lever
24
being driven by driving means (not shown), and
27
denotes a driven roller opposed to the disk roller
26
.
Indicated at
32
are a pair of swash plate cams adapted to engage a plurality of trays
31
accommodated within the magazine
19
and operate on the disk rotation driving section
20
so as to create a gap E during planar movement of the disk, the gap E being at least not smaller than the disk thickness and formed in a rotational axis direction of the disk
25
selected by a magazine moving means (not shown).
The disk rotation driving section
20
is made up of a disk rotating motor
21
, a disk clamping hub
22
, a disk damper
23
, an actuating lever
24
, a disk
25
, a disk roller
26
, a driven roller
27
, and the swash plate cam
32
.
The operation of this disk device will be described below.
When calling any of plurality of disks
25
stored in the magazine
19
, the magazine is moved in an arrow F direction in
FIG. 174
by driving means and a desired disk position is established within the magazine.
Then, the actuating lever
24
in the magazine
19
operates, the disk
25
slides on a disk guide portion
35
formed within the magazine, and a front end of the disk
25
comes into engagement between the disk roller
26
and the driven roller
27
in the disk rotation driving section
20
. Then, with rotational movement of the disk roller
26
, the disk
25
is conveyed to the position of the disk damper
23
and the disk clamping hub
22
mounted on the shaft of the disk rotating motor
21
. Subsequently, the position where the disk
25
is to be clamped is confirmed by a disk detecting means (not shown), and the disk clamper, as well as the disk roller
26
and the driven roller
27
, are moved toward the disk clamping hub
22
by driving means, whereby the disk
25
is clamped.
Simultaneously with the movement of the driven roller
27
toward the disk clamping hub
22
, the pair of swash plate cams
32
provided in the disk rotation driving section
20
are moved to the magazine
19
side by driving means, causing trays
31
to tilt so that an appropriate gap E is formed as shown in FIG.
175
.
A disk device (in-dash type disk device) provided in the interior thereof with a disk storing mechanism is proposed, for example, in Japanese Laid Open Patent Hei 10-208361(1998).
FIG. 177
is an entire structure diagram of this proposed disk device and
FIG. 178
is a structure diagram showing the structure of an internal principal portion of the disk device.
In
FIG. 177
, reference numeral
1
denotes a front panel, which is attached to a bottom plate
2
. On a front side of the front panel
1
are provided various operating units
3
-
6
and a display unit
7
.
Reference numeral
8
denotes an outer case which covers a disk changer,
9
denotes an insulator provided on the bottom plate
2
,
10
denotes a main tray projected from an opening la of the front panel
1
, and
11
denotes a sub-tray capable of sliding in the direction of arrow P or Q while being guided by the main tray
10
. Onto the sub-tray
11
is fed a disk
12
after replacement.
FIG. 178
shows a principal portion in the interior of the disk device. According to the structure illustrated in the same figure, a group of spacers supported by a disk holding means are driven by a vertical driving means, an arbitrary disk is selected out of a group of disks and is conveyed up to a recording/reproducing position by a horizontal conveyance means. Further, with a rise reset means, the disk is prevented from coming off from a spacer on both spindles. Likewise, with a disk pressing means, the disk is prevented from coming off from the spacer, and with a spacer anti-dislodgment means, the dislodgment of the spacer from a lower spindle is prevented.
In the conventional disk devices which are not the in-dash type, it is necessary to use a magazine case and hence it is impossible to load and unload disks selectively one by one; besides, an increase in size of the disk device results. Moreover, since a portable magazine case is used, it is technically difficult to disassemble each disk storing rack within the disk device, so when forming a gap between a disk to be reproduced and a disk opposed thereto and when the gap is to be made large because it is only one end that can be opened, there arises the necessity of forming a space within the disk device correspondingly to the size of gap, thus leading to an increase in size of the disk device.
Further, since a portable magazine case is used, it is extremely difficult to separate the disk storing racks from one another with each disk storing rack inclined within the disk device.
In the conventional in-dash type disk device, when a disk is to be held within the disk device, the disk is conveyed and held with only the rotational movement force of a roller serving as a disk conveying means until the disk reaches a disk holding section through a disk inlet. With this configuration, the disk is apt to become unstable during the conveyance thereof, and at the worst the disk comes into abutment against a component within the disk device and then it is damaged.
In the conventional in-dash type disk device, when a disk is to be supported, that is, when a spacer for supporting a disk is to be fixed, for example at the time of replacing a disk stored within the disk device or at the time of reproducing a disk, shaft portions provided at upper and lower positions of the disk device are coupled together, thereafter, pawl port
