For the on-vehicle type, a disk is placed on a table 5 from the opening 18a of the plate 18, and the disk is rotated by the table 5 after the plate 18 is moved as shown by an arrow B to perform reproduction. For the installed type, the loading is carried out only by reciprocal motion shown by the arrow B and for the portable type, the chassis 1 is fixed to a housing provided with a lid body rotatably, the lid body is elevated, and the disk is mounted on the table 5 to perform its reproduction.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention relates to a recording/reproducing device, particularly a digital audio device.
The present invention relates to a digital signal reproducing device for reproducing a recording medium on which analog signals are recorded, such as a disk or a digital audio tape.

(2) Prior art As for this type of conventional digital signal regeneration "A [7], devices are used that are shaped to suit the type of usage, such as the so-called boatful type, vehicle-mounted type, and stationary type. It was common for i8a construction to be made individually to suit various shapes, such as a bow.

(3) Problems to be Solved by the Invention Even with these various shapes, the part that reproduces the signal from the recording medium is common. However, 8! Since both the structural parts and the circuit parts are individually designed and manufactured according to the specifications, the number of man-hours required for design and manufacture is large, resulting in very high costs.

(4) Means for solving the problems The present invention has been made in view of the above points, and aims to reduce the number of man-hours and costs required for designing and manufacturing a recording/reproducing device. a recording medium drive unit that drives a recording medium for recording and reproducing signals from the recording medium; a node for recording and reproducing signals from the recording medium; a head feeding mechanism for transporting the head in accordance with the recording and reproducing operation; It consists of a sub-chassis in which a medium drive unit and the head feeder (K) are placed, and a loading tL that connects the sub-chassis.

(5) Function In this configuration, the recording medium nest moving part, the spatula I, and the head feeding mechanism are integrated from the substantive; It becomes possible to achieve commonality.

(6) Examples Hereinafter, the present invention will be explained with reference to the drawing ζ.

FIG. 1 is a partially sectional perspective view showing an embodiment of a recording/reproducing apparatus according to the present invention, and shows a case where the recording/reproducing apparatus according to the present invention is used as a vehicle-mounted type.

FIG. 1 Here, a spindle motor 3 is mounted on the sub-chassis 1, and a turntable 5 is fixedly attached to the rotating shaft (not shown) of the spindle motor 3. A digital audio disc (not shown) is placed on Chiful 5.Optical/button 4
is embedded inside the carrier 7, and one end of the gear carrier 7 is provided with a rack gear 8 (see Figure 3!).

This is to match the Y direction. The kite rail 9 is fixed to the sub-chassis 1 by a stopper 10 (see Fig. 3, 5).
, the sub-chassis 1 is attached to a loading plate 18 via a vibration-proof rubber 12.

Loading the disc is loading play 1.1
8. The loading plate 18 is pushed out to the front of the housing 17 by a rope mechanism consisting of a motor 19, a gear 20, etc.

The rotating blade 18 is provided with an opening 18a for placing the disc thereon, and after placing the disc on the turntable 5 through this opening 18a, the loading blade 1.18 or the motor 19 As the gears 20 and the like move in the direction of arrow B, the engagement pins 21 provided in the loading plates 1 and 18 are guided to the guide holes 171 formed in the housing 17, and are moved to the lower right of FIG. move in the direction. After this moving operation, the disc is driven to rotate on the turntable 5 to perform regeneration.

FIG. 2 is a partially sectional perspective view showing an embodiment of a pond according to the invention. The same components as in Figure 1 have the same y and g.
, ¥ numbers will be added and explanations will be omitted.

FIG. 2 shows a case where the recording/reproducing apparatus according to the present invention is used as a stationary type. The sub-chassis 1 on which the spindle motor 3 etc. is mounted is loaded with a loading plate 1.

I get beaten up. The loading plate 1.18 is provided with an opening 18a for placing the disc. After placing the disc on the turntable 5 through this opening 18a, the loading plate 18 is moved to the motor 19. It is driven by gears 20 and the like to move in the direction of arrow B. In this embodiment, unlike the embodiment shown in FIG. 1, loading is performed only by reciprocating movement in the direction of arrow B.

FIG. 3 is a partially sectional perspective view showing a vortal type digital (No. 5) reproducing device using a sub-chassis made into a common component according to the present invention.

In FIG. 3, a spindle motor 3 is mounted on the sub-chassis 1, and a turntable 5 is fixed to a rotating shaft (not shown) of the spindle motor 3.

A digital audio disc (not shown) is placed on the turntable 5. The optical spatula F tl is incorporated inside a carrier 7 , and a rack gear 8 is provided at one end of the gear carrier 7 . The carrier 7 moves in the direction of arrow A as the rack gear 8 meshes with a pinion gear (not shown), and slides on the cylindrical rail 9. The direction of the arrows, \ and the axial direction of the kitrail 9 are made to coincide with the radial direction of the digital audio disc. Kiterail 9 is stopper 1

When placing the digital audio disc on the turntable δ, the lid 1 is lifted up as shown in FIG. The recording and reproducing apparatus shown in FIG. 3 is used alone as a portable type.

(7) Effects of the invention As explained above, there is a recording medium drive unit that drives a recording medium for recording and reproducing signals, a head for recording and reproducing signals from the recording medium, and a head that is moved in accordance with the recording and reproducing operation. A head feeding mechanism for the storage, a sub-chassis on which the recording medium drive unit and the head feeding mechanism are mounted, and a loading mechanism for loading the sub-chassis? Because of the i+, the recording medium drive unit, head, and head feeding mechanism integrated with the subshade can be made into a portable type, vehicle-mounted type, or
It becomes possible to reduce the number of man-hours and costs required for design and manufacturing by using common parts to suit the form of a stationary type or the like.
