JPS61151870A - Door open and close mechanism of disk player - Google Patents

Abstract

PURPOSE:To avoid the danger where a hand is nipped by a door of a disk player when a disk is loaded and to inhibit the opening of the door in a disk reproduction mode, by holding a door lever rotatable or slidably through a carry which holds a disk type recording medium. CONSTITUTION:A support shaft 6b is provided at a projection part 6a on the back face at both ends of a loading door 6 which covers the entire surface of a carry 2, and a door 6 is supported rotatably and slidably by a door lever 5 together with the engagement secured with a slit 5a of the lever 5. When the carry 2 is carried into a player cabinet 8 from the automatic loading start position and reaches the carry storing position, both upper and lower end parts of the door 6 have contact with the upper and lower fringes 8a and 8b of an opening of the cabinet 8. Thus the position of the door 6 is decided. When the carry 2 moves down, the lever 5 is turned and the shaft 6b moves along the slit 5a. Then a coil spring 7 is extended and the door 6 moves apart from the front face of the carry 2. Then the carry 2 reaches the reproduction position of a disk.

Description

DETAILED DESCRIPTION OF THE INVENTION B) Industrial Application Field This invention relates to a door opening/closing mechanism in a front-loading disc player.

(B) Conventional technology Conventionally, the door mechanism of a front-loading disc player has been (1) rotatably supported on the edge of the opening through which the cap enters and exits, and is always biased toward the closed position by a spring. (2) It is supported in a vertically movable manner on the front of the loading base that transports the disc, and at the disc exchange position it is lowered to the front of the loading base, and at the disc playback position it is raised to connect the loading base and the player. Some are known that cover the opening between the cabinet and the cabinet.

However, for safety reasons, there is a risk of getting your hand caught in the door when loading a disc, and the door can be opened while the disc is playing.
It is necessary to provide means for detecting when the door is opened and a device for reversing the loading mechanism in the event of an overload, which has the disadvantage of complicating the mechanism.

(c) Problems to be solved by the invention The purpose of this invention is to improve the above-mentioned drawbacks of the conventional device, so that there is no risk of getting your hand caught in the door when loading, and it is also possible to open the door while playing a disc. The purpose of the present invention is to provide a door opening/closing mechanism that cannot be opened and closed.

(d) Means for Solving the Problems In order to achieve the above object, the door opening/closing mechanism of the present invention has a door opening/closing mechanism in which a disc-shaped recording medium is placed, a disc exchange position protruding forward from the player cabinet, and a disc exchange position inside the player cabinet. A carrier 4 that moves horizontally and vertically between the playback position and the playback position, a loading door that is rotatably and slidably supported in a long hole of a door lever that is supported on both sides of the carrier 4, and 4 and a coil spring stretched between the bolts of the O-ding door.

(E) Function With this structure, when the front of the carry is outside the player cabinet, the loading door is located at the front of the carry, and when the front of the carry is inside the player cabinet, the coil spring stretches and the loading door is closed. Carry 4 away from the front of the carry.
cover the openings for entry and exit.

(f) Embodiments Examples of the present invention will be described with reference to the drawings. 1 to 3 show right side views at the autoloading start position, carry storage position, and disc playback position, respectively.

A carrier 42 on which the disk-shaped recording medium 1 is placed is supported so as to be movable in the front and back direction with respect to the autoloading mechanism, and the disk exchange position further left than shown in FIG. 1 and the autoloading start position in the same figure are The automatic loading mechanism moves between the automatic loading start position and the disc playback position.

The autoloading mechanism moves the carry 42 horizontally between the autoloading start position and the carry storage position and vertically between the carry storage position and the disc playback position, and moves the carry 42 horizontally between the autoloading start position and the carry storage position and vertically between the carry storage position and the disc playback position. The upper disk-shaped recording medium 1 is held by the disk clamp mechanism 3.
It is designed to be clamped onto the turntable 4.

A door lever 5 having a long hole 5a at its tip is rotatably supported at its base end on both left and right sides in front of the carrier 42.

A support shaft 6b is provided to protrude from a protrusion 6a on the rear surface of both ends of the loading door 6 that covers the entire surface of the carrier 42.
b engages with the elongated hole 5a of the door lever 5, so that the loading door 6 is rotatably and slidably supported by the door lever 5.

A coil spring 7 is stretched between the upper part of the protrusion 6a of the loading door 6 and the lower front end of the carrier 42, and the first
In the state shown in the figure, the upper bent part of the protrusion 6a is in the carrier 42.
The O-ding door 6 is positioned at the front of the carrier 42 so as to be in contact with the green top surface of the carrier 42 .

When the carrier 42 is carried into the player cabinet 8, the upper and lower ends of the loading door 6 are positioned in contact with the upper and lower edges 8a18b of the opening of the player cabinet 8, respectively.

Next, its operation will be explained.

When the carrier 42 is carried into the player cabinet 8 from the autoloading start position shown in FIG. 1 and reaches the carry storage position, the loading door 6 opens at both upper and lower ends as shown in FIG. are positioned by coming into contact with the upper and lower edges 8a, 8b of the opening of the player cabinet 8.

Next, when the carrier 42 begins to descend, the door lever 5 rotates upward, the support shaft 6b moves along the elongated hole 5a, the coil spring 7 extends, and the loading door 6 moves toward the carrier 2.
When the carry 2 leaves the front surface of the disc and reaches the disc playback position, the state shown in FIG. 3 is reached.

When the disc is unloaded, an operation that is completely opposite to the above-mentioned operation is performed.

(G) As described in detail of the invention, the door opening/closing mechanism of the disc player of the present invention has a disc-shaped recording medium placed thereon, a disc exchange position protruding forward from the player cabinet, and a disc playback position inside the player cabinet. A loading door that is rotatably and slidably supported by a long hole in the door lever that is pivoted on both sides of the carry, and a tension tensioner between the carry and the loading door. It consists of a suspended coil spring, and when the front of the carry is outside the player cabinet, the
- The loading door is located at the front of the carry, and when the front of the carry is inside the player cabinet, the loading door covers the opening through which the carry enters and exits, so there is no risk of getting your hands caught in the door when loading, and disc Since the door cannot be opened during playback, there is no need to take special safety measures as with conventional equipment, and since the front part of the carry is not exposed, there is no need to provide any exterior parts in this area. It's something that doesn't exist.
