Description

[Detailed description of the invention] This invention relates to a front door opening/closing device for a record player in which a turntable is supported so as to be movable in the front and rear directions relative to the player cabinet. is movably supported between a vertical position covering the front of the player cabinet and a horizontal position inside the player cabinet, and the front door is moved by moving a slide lever connected near the top end of the front door in the front and back direction. By opening and closing the front door, it is easy to open and close the front door, and furthermore, since the front door is pulled into the player cabinet when opened, it does not interfere with player operation.

Conventionally, in order to reduce the space required by a record player (especially the space above it), the turntable was supported so that it could move forward and backward relative to the player cabinet, and the front door was rotated upward when in use. There is a known device in which the turntable is pulled forward.

However, when using such a product,
The front door protruded above and in front of the turntable, making it difficult to change records or operate the tone arm.

The purpose of this invention is to provide a simple and reliable mechanism for moving such a record player to a position that does not interfere with player operation when the front door is opened.

An embodiment of this invention will be described with reference to the drawings.

Slide base 2 with turntable 1 placed on it
is supported so as to be movable in the front and rear directions (left and right directions in the figure) with respect to the player cabinet 3.

A front door 4 is provided at a position covering the upper opening of the slide base 2, and two upper and lower guide pins 5 and 6 having rollers protrude from both sides of the front door 4.
are engaged with guide grooves 7 provided on both side walls of the player cabinet 3, and are rotatably and slidably supported.

The guide groove 7 consists of a horizontal portion and a vertical portion that is continuously bent downward in front of the horizontal portion, and the inside of the bent portion is scratched in an arc shape so that the lower guide pin 6 can move smoothly. ing.

A slide lever 8 is supported on one side wall of the player cabinet so as to be movable back and forth, and is always urged forward by a spring 9.

The front end of the slide lever 8 is connected to the guide pin 5 on the upper side of the front door, and the rear end thereof is connected to the rotating lever 10.
Each is pivotally supported at the upper end of the .

The rotary lever 10 is bent in a dogleg shape, and the second
As shown in the figure, when the slide base 2 is in front of the storage position, the lower side of the rotating lever 10 comes into contact with the roller 11 provided on the slide base and is held in the position shown in the figure. It's getting old.

Next, its operation will be explained.

In the stored state shown in FIG. 1, when the slide base 2 is moved slightly forward (to the left in the drawing) manually or by a slide base drive mechanism (not shown), the roller 11 moves toward the rotating lever 1.
0 and rotates it clockwise, causing the slide lever 8 to move backward against the spring 9.

Then, the guide pin 5 on the upper side of the front door moves backward, and the guide pin 6 on the lower side moves first upward and then backward, and the front door 4 rises while rotating. Move to the horizontal position shown.

When the slide base 2 is further moved forward, the roller 11 moves while contacting the lower side of the rotating lever 10, and the front door 4 is held in the state shown in the figure.

In the operating condition shown in FIG. 2, the turntable 1 protrudes forward from the player cabinet and the front door 4 is retracted into the player cabinet, so there is no problem in replacing the record. It is easy to operate the tone arm.

When the performance is finished and the slide base 2 is moved backward, the rotary lever 10 is moved just before the storage position.
rotates counterclockwise, the slide lever 8 moves forward, and the front door 4 moves to the closed position (vertical position) shown in FIG.

Finally, the roller 11 separates from the rotating lever 10, and the front door 4 is accurately positioned in the closed position by the biasing force of the spring 9.

As explained above, the record player front door opening/closing device of this invention supports the front door movably between the vertical position covering the front of the player cabinet and the horizontal position inside the player cabinet. ,
By moving the slide lever connected near the top of the front door in the front and rear directions to open and close the front door, it is easy to open and close the front door, and when it is opened, it can be pulled into the player cabinet. This has the unique effect of not hindering player operations.

In the above embodiment, the slide lever is moved in conjunction with the slide lever, but it is not necessary to do so, and if the two are not coupled, the slide lever may be moved outside the player cabinet. The slide lever may be moved by providing a means (for example, a handle) that can be operated from the handle.
