Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a magazine-type disk player, and is a loading method in which multiple trays each containing a plurality of disks are selectively loaded to an optical pickup device inside the magazine. Regarding equipment.

``Prior Art'' Conventionally, a steel ball is fitted between a pair of loading arms, and one loading arm is slid and locked in an appropriate position to load the tray to an optical pickup device. There is a loading mechanism that allows you to

``Problems to be Solved by the Invention'' When the loading arm is incorporated into the loading mechanism, one loading arm is attached to the chassis, and a steel ball is fitted into the holding hole of the arm, and then the loading arm is assembled into the loading mechanism. To attach the other loading arm to the arm,
It was not easy to insert the steel balls, the number of assembly steps was increased, and the overall assembly was difficult due to the presence of other loading members.

``Means for Solving the Problems'' However, the present invention has a pair of loading arms for loading the tray to the optical pickup device, and the other loading arm is slidably attached to one loading arm. In addition, in a structure in which a sphere for position holding is provided between each arm, when the outer loading arm is manually slid outside of this action movement range after assembly, it aligns with the sphere holding hole of the inner loading arm. It is characterized by a sphere insertion hole provided in the outer loading arm.

"Function" Therefore, the pair of loading arms can be easily incorporated into the loading mechanism, and the work of loading the spheres can be easily performed, reducing the number of assembly steps and improving work efficiency.

"Embodiments" Examples of the present invention will be described below in detail based on the drawings. Fig. 1 is a partial explanatory view of the loading mechanism, and Fig. 2 is a cross-sectional view of the same.The loading arm 2 on the working side is slidably superimposed on the upper surface of the loading arm 1 on the fixed side attached to the sub-chassis. A steel ball 3, which is a sphere, is fitted between the loading arms 1 and 2 to fix the loading arm 2 on the working side, and a holding hole 4 into which the ball 3 is fitted is formed in the loading arm 1 on the fixed side. At the same time, a spring 5 that presses the ball 3 against the loading arm 2 on the active side is inserted into the holding hole 4.
A plurality of locking position fixing holes 6 into which the balls 3 are fitted are provided in parallel on the loading arm 2 on the active side, and the loading arm 2
When the loading arm 2 slides in the acting direction against the force of the spring 7, the ball 3 is appropriately fitted into the fixing hole 6 through the force of the spring 5, and the loading arm 2 is configured to be held on the loading arm 1 at the sliding end.

Also, from the outside after attaching the loading arm 2 on the working side to the loading arm 1 on the fixed side,
A sphere insertion hole 8 into which a steel ball 3 and a spring 5 can be inserted into the holding hole 4 is provided in the loading arm 2 on the active side, and a notch 9 of the insertion hole 8 supports one end of the spring 7.

The insertion hole 8 wraps over the holding hole 4 only when the loading arm 2 on the active side is manually slid out of its active movement range.

"Effects of the Invention" As is clear from the above embodiments, the present invention includes a pair of loading arms 1 and 2 for loading a tray to an optical pickup device.
In a structure in which one loading arm 1 is slidably attached to the other loading arm 2, and a sphere 3 for position retention is provided between each arm 1, 2, after assembly, the outer loading arm 2 is attached to this By providing the outer loading arm 2 with a sphere insertion hole 8 that matches the sphere holding hole 4 of the inner loading arm 1 when manually slid out of the working movement range, the pair of loading arms 1, 2 can be easily incorporated into the loading mechanism, and the work of loading the sphere 3 can be easily performed, reducing assembly man-hours and improving work efficiency. play.
