Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a composite device in which a first device for reading information from a disk and a second device for reading information from a cassette tape are housed in the same housing.

(b) Conventional technology Conventionally, as shown in, for example, Japanese Utility Model Application Publication No. 111405/1983, there has been a composite system called 3-in-one in which a cassette deck part, a tuner part, and a record player part are housed in the same housing. Recently, with the spread of compact discs (referred to as CDs), devices equipped with a CD player instead of a record player are being commercialized.

(c) Problems to be solved by the invention However, in the case of composite equipment such as this, in which the cassette deck section, the tuner section, and the CD player section are housed in the same housing, the cassette deck section and the CD player section are generally Since these parts are located at separate locations, separate drive motors must be provided to drive each part, which poses a problem in terms of achieving smaller size, lighter weight, and lower cost.

(d) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a first device that reads information from a disk and a second device that reads information from a cassette tape, all housed in the same housing. The driving parts of the first equipment and the second equipment are arranged close to each other, and a transmission mechanism is arranged to transmit power from a single motor to each of the driving parts. Further, the transmission mechanism includes a first connecting portion that connects the motor and a drive section of the first device, and a first connecting portion that connects the motor and a tape feeding drive section of the second device at a first position. , in a second position, the motor and the tape winding drive section of the second device are connected, and in a third position, the switch is located in a non-coupling position between the tape feeding drive section and the tape winding drive section. It is characterized by comprising a connecting part.

(e) Operation When playing a disc, the switching connection section is positioned at the third position (non-connection position), and the driving force of the motor is supplied only to the drive section for the disk. During tape playback, the switching connection section is positioned at the first position or the second position, and the driving force of the motor is
It is supplied not only to the disk drive unit but also to the tape drive unit.

(F) Embodiment An embodiment of the present invention will be described below with reference to the drawings. That is, 1 in the figure is a housing that houses a cassette deck part, a tuner part, and a CD player part, and on the front side of the housing 1 there is a group of operation buttons for controlling the operation of each part and a tuning display part 2 of the tuner part. and CD
A display section 3 is provided for displaying the track and time of the player section. 4 is the CD mounting recess of the CD player section formed on the top side of the housing 1; 5 is the CD mounting recess of the housing 1;
A cassette mounting recess 6 of the cassette deck portion is formed by at least partially overlapping the CD mounting recess 4 on the upper surface side and the portion excluding the turntable described later.
A finger insertion recess 7 is formed adjacent to the CD insertion recess 4 in order to facilitate the insertion and removal of a CD into the CD insertion recess 4, and 7 is a finger insertion recess 7 between the CD insertion recess 4, its finger insertion recess 6, and a cassette installation. A lid is provided on the upper surface of the housing 1 to open and close the recess 5, and the lid 7 has a see-through window so that the inside of the CD mounting recess 4 and the cassette mounting recess 5 can be viewed from the outside. 7a is provided. Incidentally, reference numeral 8 denotes a handle recess formed on the upper surface side of the casing 1 adjacent to the lid 7 for manually opening and closing the lid 7.

Reference numeral 9 denotes a turntable protruding into the CD mounting recess 4 in order to rotationally drive the CD 10.
It is directly connected to the rotating shaft 12a of No. 2. 13,
Reference numeral 13' indicates a pair of reel shafts protruding into the cassette mounting recess 5 to engage with the cassette 14;
A relay gear 18 is a relay gear 1 to which rotational driving force is transmitted from a drive pulley 16 fixed to a rotating shaft 12a of a CD drive motor 12 through a belt 17.
Reference numeral 5 designates a rotatably arranged relay lever, and the relay lever 18 is rotatably supported by a shaft 19 on the base plate 11. When the cassette deck section is not in operation, it is in a neutral position and the relay gear 15 is connected to the reel shaft. 13,1
Although it is separated from the reel gears 13a and 13a' that are integrated with the reel gears 3', when the cassette deck section is operated, that is, when operations such as playback, fast forwarding, and rewinding are performed, the relay gears are rotated to the left and right positions according to each operation. 1
5 is meshed with the reel gear 13a or 13a'. Reference numerals 20 and 21 denote a flywheel and a capstan shaft to which rotational driving force is transmitted from the reel shaft 13 through the belt 22, which rotate together when the reel shaft 13 is driven to rotate. The rotational speed and direction of the CD drive motor 12 is controlled by a microcomputer in response to operations such as playback, fast forwarding, and rewinding of the cassette deck.

Therefore, according to the composite device of the present invention, when the cassette deck section is operated, for example, when playing or fast forwarding,
Since the relay gear 15 meshes with the right reel gear 13a as shown in FIG.
The rotational driving force of 2 is transmitted to the reel shaft 13, flywheel 20, and capstan shaft 21, and during the rewinding operation of the cassette deck section, the relay gear 15 meshes with the left reel gear 13a' as shown in FIG. Therefore, the rotational driving force of the CD drive motor 12 is transmitted to the reel shaft 13'. Next, when operating the CD player section instead of the cassette deck section, the relay gear 1
5 are both reel gears 13a, 13 as shown in FIG.
It is in a neutral position where it does not mesh with a', and the rotational driving force of the CD drive motor 12 is transmitted only to the turntable 9.

In this embodiment, the turntable of the CD player section is directly connected to the rotating shaft of the CD drive motor, so even when only the cassette deck section is operating,
Although the turntable of the CD player section is driven to rotate, the turntable may be prevented from rotating when only the cassette deck section is operated via a separate relay mechanism. In addition, in this embodiment, the CD drive motor is controlled by a microcomputer in accordance with various operations on the cassette deck, but the CD drive motor can be decelerated during transmission of driving force without changing the rotation direction or rotation speed. The direction of rotation may be reversed, and in this way both the CD player section and the cassette deck section can be operated.

(g) Effects of the invention As mentioned above, according to the invention, the disk drive unit and the tape drive unit are driven by a single drive unit, so that the compound equipment incorporating them can be made smaller. , weight and cost can be achieved. or,
During disc playback, the motor is connected only to the disc drive unit, so that the disc rotation control, which requires high speed and high precision, can be achieved at the same time.
