Abstract

This invention relates to a multi-disc player capable of storing a plurality of discs and sequentially selecting arbitrary discs for continued reproduction. An elevation rack disposed at one of the ends of a loading base for supplying discs selectively from a magazine to a disc reproduction unit is driven vertically by one elevation cam disposed on the main body side of the mechanism to drive a horizontal support structure consisting of an elevation lever and an auxiliary elevation lever that are disposed on the side part of the loading base, so that the loading base can be driven vertically as a whole while keeping its horizontal state. The elevation speed can be improved and the elevation mechanism can be simplified by reducing the weight of the loading base as a whole.

Manorechi Disk Player

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc player, and more particularly to a multi-disc player capable of storing a plurality of discs and sequentially selecting any of the stored discs for continuous performance. is there.

Background technology

In recent years, various types of digital audio discs have been released, and their usage has increased rapidly.] Various multi-disc players have been developed that can continuously play 9, 6 to 10 discs in sequence. I have. Many of these multi-player players use a laser beam to move the entire optical pickup block up and down to read the signal. Therefore, the mechanism for driving this was complicated and expensive.

The following is a description of the conventional manolec disc player described above.

Fig. 8 shows a conventional manolec disc player. In FIG. ⁸ , the discs 102 mounted on the disc holders 101a of the trays 111 are provided with shelves ¹⁰ formed in ^six stages of a magazine 103. It is arranged in 3a in order, stored and stored, and each can be pulled out and stored.

104 is a man-made disk. The main mechanism of the layer A magazine base 1 formed in a U-shape for storing magazines 1 The OS 1 always holds the magazine ¹ O 3 in a fixed position o

1 O 6 is a magazine pusher and a repeller.]) The magazine is always pushed in the direction by the insertion of the magazine 103, but is pushed out in the mouth direction by the extension spring 107.

Reference numeral 1108 denotes a magazine opening repeller for locking the magazine.] The spring 1109 engages with the recess 1OSb formed on the side wall of the magazine 103 to engage the magazine 103. It is configured to prevent pushing toward the mouth. .

When 1 O is a plunger], and when removing the magazine 103] By energizing, the lock lever 108 and the recess 103 b formed in the side wall of the magazine 103 are energized. Then, the magazine 103 is configured to be pushed out by the magazine pushing out lever 106.

1 1 1 is a speed control device for controlling the extrusion speed of the magazine. ]), The magazine push-out lever 1 O 6 is pressed against to control the push-out speed of the magazine 1 O ³ .

1 1 ² is a tray hook]? It is guided by a guide shaft ¹ 14 provided on the mouth-drilling base 1 13 that supplies the tray 101 to the playing start position. It is configured to slide in the mouth direction. ^{1 1 5'm} in Tray full-click Oh in Kure District dynamic motor-] ?, pulleys 1 1 6, belt 1 1 7 provided on the Rodei Ngube scan go-between, tray full-click 1 1 2 Drive in the mouth direction to And 1 O recess 1 0 1 b provided in 1 is engaged with the preparative Reifu click ¹ 1 2, pull the bets Rei ¹ 〇 ¹ from the magazine 1 0 3 is configured such that housing.

1.18 is provided on the loading base 113, and guides the tray 101 on the turntable 120 of the optical pickup block 119 to start playing the disk 102. It is a training guide for

1 2 1 is the screen screw] ?, loading. 3 places around the loading base 1 1 3 to move the base 1 1 3 up and down while holding it horizontally. and main screw portion 1 ^{2 2} mates provided, and is configured such that raising and lowering the Rodei Ngubesu 1 1 3 vertically. '

1 2 3 is a timing belt for engaging the small gear 1 2 4 provided at the lower part of the three screw screws 1 2 1 to drive the three screw screws. A]? Elevating drive motor — It is configured to be driven by 125.

The operation of the multi-layer player configured as described above will be described below.

Six of di scan click 1 0 2 and the tray ¹ 〇 ¹ and the magazine 1 0 3 housing the, and揷入in the magazine base 1 0 5, lever out press magazine one;! Locked in place by the push-back force of 06 and the magazine lock lever 1 O 8. Next, the loading base ¹¹³ is moved up and down by the rotation of the elevator drive 125, so that the tray hook ^{112 and the} recessed portion 101a of the tray 101 engage with each other. Stop. Subsequently, the train drive motor 1 15 rotates forward, and the train 1 1 2 pulls out the tray 10 1 in the direction of the arrow. When you reach the center of the center, the music stops and the performance starts.

When the performance is over, the tray drive motor 1 15 reverses, and the tray hook 1 1 2 pushes the tray 10 1 back in the direction of the arrow and stores it in the magazine 10 3 I do.

When power is supplied to the plunger 110, the magazine

The engagement between 108 and the recess 103b of the magazine 103 is released, and the magazine 103 is pushed out in the direction of the mouth by the magazine push lever 106, and the multi- Can be taken out of the main body of the player. 'However, in the above configuration, the heavy optical pick-up block 119 and the loading base 113 incorporating a truck drive motor etc. are three screws. In addition to the need for a strong elevating structure for elevating and lowering by the unit 121, the whole structure was complex and]) expensive. ·

In addition, there is a problem that it is difficult to increase the ascending and descending speed because the entire weight of the loading base 113 is heavy.

Disclosure of the invention

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and comprises a heavy optical pickup block, a train hook, a train hook drive motor, and the like on a main body side to form a loading base. The purpose of the present invention is to provide a manoleci disc player that can be made lighter to increase the elevating speed and simplify the elevating structure. * In order to solve the above problems, the present invention disc player

(1) A magazine in which a plurality of disks are arranged and stored in order, and an arbitrary disk which is moved up and down in the vertical direction facing the magazine.

5) a loading base for sequentially selecting 5, a lifting drive of the mouth-loading base for transmitting a lifting drive force to a part of the loading base, one end of which is pivotally supported by the loading base, and the other end of which is supported by the loading base. A lifting lever slidably supported by the mechanism body; and a lifting aid, one end of which is supported by the mechanism body and the other end of which is slidably supported by the loading base. Leva

A pin is provided at a substantially central portion of one of the lifting lever and the lifting assistance lever, and a long hole is provided at a substantially central portion of the other, and the lifting lever and the lifting assistance lever are connected to the pin 5j9 The loading base is held horizontally by the levers and the lifting drive unit is engaged with the levers. It is configured to move the moving base up and down. '

(2) Further, the lifting drive unit includes a lifting rack provided on a part of the loading base, a lifting cam provided on the mechanism main body for driving the lifting rack, and a lifting cam. From the driving source] 9,

The lifting rack is driven up and down by rotating the lifting and lowering force by a driving force from the driving source.

According to the above configuration, one lifting rack provided at one end of the loading base is provided on ^one lifting cam provided on the mechanism body side. • Therefore, it is driven up and down to drive the leveling structure of the loading base, which consists of the lifting and lowering levers and the lifting and lowering levers, provided on the side of the loading base. It is configured to drive the entire tuning base up and down.

As a result, vertical driving can be performed with only one lifting rack and lifting force, so the vertical driving load is light, and vertical driving can be performed at high speed.
