The present invention relates to an optical disc player with a radio in which an optical disc player and a radio receiver are integrated.

The optical disc player 1 with a radio of the present invention has a chuck portion (a disk table) 25 for loading an optical disk and a player portion (rotary driving means) for rotationally driving an optical disk loaded on the chuck portion (disc table) 25 ( 26 and a readout means for reading information from the optical disc rotated by the player portion (rotation drive means) 26, and rotating movement of the optical disc by the player portion (rotation drive means) 26. The chuck portion (disc table) 25 is formed in the shape of an upper portion to enable the player body (body case) 2 and has a disc loading portion (disc storage portion) 24 protruding from the bottom surface. An image which is rotatably attached to open and close the disc stacking unit (disc storage unit) 24 with respect to the player body 2, and closes the disc stacking unit (disc storage unit) 24. In addition to the disk table 5, the lid body (lid) 3 and the chuck portion (holding portion), which are installed to protrude from the rear surface 3a, the chuck portion (holding portion) 13 which holds the optical disk rotatable. (13) is provided, and the radio receiver (18) is arranged in the recess (15) formed on the rear surface (3a).

As a result, the entire player can be formed compact and thin, and the optical disc and the player portion (rotation drive means) 26 can be prevented from being damaged.

BACKGROUND ART An optical disc player with a radio in which a player for reproducing an optical disc such as a compact disc and a radio receiver are integrated. In some conventional players, the player section and the radio receiver section are housed in the player body.

Since the player portion (rotation drive means) and the radio receiver portion are housed in the same case, the case becomes large and it is difficult to miniaturize and thin. In addition, since the player portion (rotation drive means) has many metal parts such as an optical head, the reception sensitivity deteriorates when the AM receiving bar antenna is provided in the radio receiver portion. In addition, since a large number of digital circuits are used in the player section (rotation drive means), the clock pulse becomes noise, which adversely affects the radio receiver section. In addition, since the player portion (rotation drive means) and the radio receiver portion are disposed in the same space, manufacturing is difficult and serviceability is also poor.

The chuck portion (holding portion) for holding the optical disk rotatably protrudes from the back side of the lid, and the chuck portion (holding portion) is provided to arrange the radio receiver in the recess formed on the back side of the lid.

The whole player can be formed compact and thin, and the optical disc and the player portion (rotation drive means) can be prevented from being damaged.

2 shows the appearance of a compact disc player 1 with a radio according to the present invention. In addition, this player 1 is a portable CD player which is compact and thin as shown.

In FIG. 2, the lid body 3 is provided in the player main body (body case) 2 freely.

Various operation buttons 4, a display unit 5, and the like are provided on the front surface of the player main body 2. In addition, the side of the player body 2, the FM / AM switch 6, tuning knob 7, the switch 6 for selecting the player operation, radio operation, operation stop (CD, RAD, OFF), volume The handle 9 and the line out terminal 10 are provided. On the surface of the lid body 3, dial scales 11 for FM and AM are provided.

FIG. 1 shows a state in which the lid body 3 is opened. One end of the lid body 3 is freely rotated by the opening / closing mechanism 12. The back surface 3a of the lid body 3 is provided with a chuck portion (holding portion) 13 for holding the disk freely to protrude from the rear surface. A decorative plate 14 covering the mechanism of the chuck portion (holding portion) 13 is provided on a part of the back surface 3a. This decorative plate 14 is provided via the edge part 14a of height h with respect to the said back surface 3a. The end portion 14a is provided with a space 15 having a height h on the rear surface 3a. Moreover, the balls 16 and 17 which the said switch 6 and the handle 7 are provided in the side part of the lid body 3 are provided.

In this embodiment, the radio receiver 18 is incorporated in the space 15. The radio receiver 18 constitutes an AM / FM receiver circuit by providing a predetermined circuit component 20, the switch 6, and the handle 7 on the printed board 19, and the thickness of the entire radio receiver 18 It is thin enough than the height h of the edge part 14a, for example, is formed by the thickness corresponding to the part shown by the virtual line 21 in this edge part 14a. The printed board 19 is formed with a cutout portion 22 for avoiding the chuck portion (holding portion) 13. In addition, the decorative plate 23 for covering the radio receiver 18 is used.

On the other hand, a disc loading part (disk storage part) 24 is provided in the part covered by the lid body 3 of the player body 2, and the disc loading part (disk storage part) 24 is described above. Along with the chuck portion (holding portion) 13, a chuck portion (disk table) 25 is provided for holding the disk freely in rotation. The player body 2 is provided with a player portion (rotary drive means) 26 including a disk drive portion, a reproduction signal processing circuit, and the like, as shown in FIG.

3 shows a state in which the radio receiver 18 is incorporated. The radio receiver 18 is provided in the space 15, and the bottom surface thereof is covered with the decorative plate 23. As shown in FIG. The decorative plate 23 and the decorative plate 14 are joined on the same plane. As the antenna at the time of radio reception, a cord such as a headphone connected to the line out terminal is used. Reference numeral 27 denotes the chassis, and 28 denotes the disk held in the chuck portions 13 and 25.

It goes without saying that the makeup plates 23 and 14 may be used as one sheet.

According to the embodiment described above, the following effects can be obtained.

(1) Since the radio receiver 18 is provided using the space 15 effectively, the entire player 1 can be made thin and can be formed in a very small size.

(2) Since the radio receiver 18 and the player (rotation drive means) 26 are provided separately, the reception sensitivity is not deteriorated or noise due to clock pulses is not applied to each other.

(3) Manufacturing becomes easy and serviceability improves.

(4) Line outs of the radio receiver 18 and the player unit (rotary drive means) 26 and amplifiers for headphones can be shared.

(5) The cords for the line out and the headphone can be used as antennas.

(6) The electric display section 5 can be shared by the radio receiver section 18 and the player section (rotation drive means) 26.

(7) Even if the player 1 is thin, it is reinforced by the printed board 19, the makeup plate 23, or the like, so that the overall strength is increased, and in particular, the chucking strength by the chucks 13 and 25 is increased. Increasingly, stable chucking can be achieved.

By installing the retainer, the radio receiver is arranged in the recess formed on the rear side, so that the entire player can be made compact and thin, thereby realizing an optical disk player with a portable radio, and at the same time eliminating deterioration in reception sensitivity and noise. Moreover, manufacture is easy and serviceability can be improved. It can also provide a thin, high mechanical strength and reliable products.

In addition, since the chuck part (disk table) and the chuck part (holding part) for holding the optical disk rotatable are provided to protrude from the rear side in the state where the disk loading part (disk storage part) is closed, the optical disk is turned on the back side when the optical disk is rotating. The optical disc and the player portion (rotation drive means) are not damaged because they do not come into contact with each other.
