Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auto-loading disc player for automatically carrying a disc such as a digital audio disc to a playing position for playing (playing). 2. Description of the Related Art FIG. 2 shows a conventional auto-loading disc player. As shown in the drawing, a tray 101 is provided so as to protrude and retract from a player housing 102 via a guide rail 103, and discs 104 and 105 are provided.
Is placed on the tray 101 and transported to a performance (reproduction) position. Although not shown, the tray 10
A driving means for moving the first motor is provided. Tray 1
In the disk carrying surface of No. 01, there are formed concave portions 101a to 101c each having an arc-shaped outer periphery capable of accommodating each disk. In the conventional auto-loading disc player shown in FIG. 2, arc-shaped outer peripheral recesses 101a to 101a are provided in a tray 101.
1c, there is a problem that the device becomes large. In addition, the arc-shaped outer peripheral concave portions 101a to 101
When taking out the disk carried by 1c, it was difficult to take out the disk. [0004] An auto-loading disc player of the present invention has been made in view of the above points, and has a large-diameter disc for carrying at least two kinds of discs having different diameters. A first circular arc-shaped outer concave portion for a small diameter disc and a second circular arc-shaped concave portion for a small-diameter disc are formed concentrically; driving means for driving the tray in a projecting and storing direction with respect to the player housing; The tray is moved between a mounting position where the disk is mounted by the driving means and a clamp position where the disk is clamped, and the disk is moved to the arc-shaped outer peripheral concave portion. In an auto-loading disc player that moves between the loading position and the clamp position while being held, The outer peripheral concave portion has an arc-shaped outer concave portion in the direction in which the tray protrudes, and is characterized in that only the first arc outer peripheral concave portion is cut off in a direction substantially perpendicular to the tray protruding direction. According to the auto-loading disc player of the present invention, the auto-loading disc player achieves a reduction in size and cost as a whole, has a large degree of freedom in design within the player housing, and has good operability. Can be provided. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An auto-loading disc player as an embodiment of the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, a tray 1 is provided so as to protrude and retract from a player housing 2 via a pair of guide rails 3. For example, three kinds of different disks 4, 5 and 6 are provided in the tray 1. It is placed on top and transported to a performance (playback) position. The discs 4 and 5 are discs having diameters of about 30 cm and 20 cm, respectively, and the other disc 6 is a compact disc having a diameter of about 12 cm. In order to move the tray 1, a rack 1 a is provided on the tray 1 along the moving direction and over substantially the entire length, and a gear 8 meshing with the rack is rotationally driven by a motor (not shown) or the like. Done. On the disk carrying surface of the tray 1, concave portions 1b to 1d having an arc-shaped outer periphery capable of accommodating the above-mentioned disks are formed concentrically and at predetermined steps.
The width B of the tray 1 is smaller than the diameters D1 and D2 of the concave portions 1c and 1d. A turntable 9 as a first pressing member is provided in the player housing 2 so that its disk carrying surface faces downward. The turntable 9 is carried on the tray 1 and is parallel to the disk carrying surface of the turntable 9. Each disk accommodated in the player housing 2 in the direction is located immediately below the disk carrying surface of the turntable 9 with a predetermined gap. The disk that has reached just below the turntable 9 is separated from the tray 1 by being lifted upward by the disk clamp mechanism 10 and is clamped against the disk holding surface of the turntable 9. The disc clamp mechanism 10 is
A disc-shaped pressing member 11 as a second pressing member for abutting against the disk and pressing the disk against the disk supporting surface of the turntable 9 and a supporting member 12 in a vertical direction, that is, at right angles to the disk supporting surface of the turntable 9. A support member 12 is provided so as to be swingable in various directions and rotatably supports a disc-shaped pressing member 11 at a free end, and a driving means (not shown) for swinging the support member 12. A carriage 13 carrying an optical pickup is disposed on the support member 12, and is guided by a guide shaft 14 so as to move along a recording surface of a disk mounted on the turntable 9. Although not shown, a driving unit for moving the carriage 13 is provided. In this embodiment, the width B of the tray 1 for carrying the disc is 20 cm in diameter.
D2 of the arc-shaped outer peripheral concave portion 1c accommodating the disk 5
Compact disc 6 smaller than 12cm in diameter
Is larger than the diameter D3 of the concave portion 1d, which is the main part, but the present invention is not limited to this configuration, and the width B may be larger than D2 and smaller than D1. As described in detail above, in the auto-loading player according to the present invention, the arc-shaped outer peripheral concave portion is
The tray has an arc-shaped outer peripheral concave portion in the projecting direction, and only a first arc-shaped outer concave portion for supporting a large-diameter disk is cut off in a direction substantially perpendicular to the tray projecting direction. [0012] With this configuration, it is possible to easily take out disks of two sizes, large and small, while having a sufficient supporting surface on which a large-diameter disk can be stably mounted, thereby improving operability. is there. In addition, since the outer peripheral portion of the disc is not exposed to the outside in the tray protruding direction since the disc has an arc-shaped outer peripheral concave portion in the protruding direction of the tray, for example, the auto loading disc player is stored in an audio rack or the like. In this case, even if the tray is accidentally projected, the disc does not directly hit the glass or the like on the front of the audio rack, so that the disc itself is not damaged. Further, the disk is reliably supported by the arc-shaped outer peripheral concave portion in the tray protruding and storing direction during transport. Further, when the disc is gripped on both sides and a part of the outer peripheral edge of the disc is placed in the arc-shaped outer concave portion, the user can easily place the disc by positioning the disc in the arc-shaped outer concave portion at the tip of the tray. Can be placed. The arc-shaped outer concave portion has an arc-shaped outer concave portion in the direction in which the tray projects, and only the first arc-shaped outer concave portion for supporting a large-diameter disk in a direction substantially perpendicular to the tray projecting direction. Because of the cutout, the arc-shaped outer peripheral concave portion for mounting the disk is reduced in size to such an extent that the arc-shaped outer peripheral concave portion does not come off from the arc-shaped outer peripheral concave portion when the large-diameter disk is transported.
