[Prior art]

 A jukebox is generally known as a disc player capable of accommodating a plurality of discs and sequentially selecting any of the discs contained therein to enable continuous performance. However, the conventional jukebox itself is extremely large and unsuitable for home use.

In recent years, it has been called a digital audio disc (hereinafter, referred to as DAD), and by recording a digital signal, the amount of information to be stored is increased as compared with a conventional audio disc in which an analog signal is input. Several types of discs have been developed and are being widely used, which are advantageous and produce little noise during playback. Among them, a disc having an outer diameter of about 12 cm, which is generally called a compact disc, is a system for recording and reading a signal using a laser beam, and it is easy to handle and enables downsizing of the entire disc player. It is a thing. Recently, a multi-disc player has been developed which can store a plurality of small DADs (for example, 5 to 6) at all times, and which is optimal as a home jukebox for playing these continuously. By the way, the small-sized DAD has a playing time of 1 hour, and can store about 1.5 times as much information as a conventional analog audio disc. Therefore, for example, six discs can hold about 120 songs if the performance time is about 3 minutes, and it is easy to cover by genre of your choice, such as jazz or enka.

A multi-disc player basically has a playing means including a turntable and a pickup, a disc holder which holds the disc and is inserted and mounted in a mounting portion in the player housing, and a disc in the disc holder. It is provided with a playing position, that is, a disc take-out and transport mechanism for transporting the disc onto the turntable. FIG. 6 shows a conventional disc holder. As shown in the figure, the disc holder is provided with a housing 101 having a disc projecting opening formed therein, and is swingably provided around a pin 102 in the vicinity of the deepest portion of the housing so that the disc has a free end portion. A protruding arm 104 for engaging the outer peripheral portion of the disk 103 to project the disk from the disk projecting opening portion, and a swingable arm 104 centered around a pin 105 so that the disk 103 has a free end portion. A holding arm 106 for engaging the outer peripheral portion to urge the disc toward the deepest portion of the housing 101, and a coil spring 107 as a biasing force imparting means for imparting a disc biasing force to the holding arm are provided. Have The disc 103 is projected from the housing 101 by pushing the trigger lever 108 in the direction of arrow T to swing the projecting arm 104 via the intermediate lever 109.

In the disc holder described above, the disc 103 in the stored state is always held by the two arms of the projecting arm 104 and the holding arm 106 and by the biasing force of the coil spring 107. Therefore, even if the disc holder receives an external vibration, the disc 103 does not slightly move in the radial direction and the vibration resistance is good.

However, the mechanism for swinging the protruding arm 104 has a complicated structure in which the intermediate lever 109 and the trigger lever 108 are provided, and these are provided in the housing. Therefore, there were problems such as an increase in product cost due to an increase in the number of parts, a decrease in mechanical reliability, and an increase in the size of the housing body.
