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 supported movably between a vertical position covering the front of the player cabinet and a horizontal position inside the player cabinet, and the front door is opened and closed in conjunction with the longitudinal movement of the slide base. This allows the player to be put into use or storage by simply taking the slide base in and out, and also makes it easier to operate the player because it does not get stuck in the player cabinet when the front door is opened. It is a point.

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 back and forth direction (left and right direction 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 protruding from each side of the front door 4 are inserted into guide grooves provided on both side walls of the player cabinet 3. 7 and is rotatably and slidably supported.

The guide groove 7 consists of a horizontal part and a part continuous in front of the horizontal part divided into upper and lower parts, and when the front door 4 is in the closed position (vertical position) shown in FIG.
The upper and lower guide pins 5 and 6 engage with a bifurcated portion of the guide groove 7.

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 upper guide pin 5 of the front door engages with a long hole vertically provided at the front end of the slide lever 8, and its rear end is pivotally supported by the upper end of the rotating lever 10.

The rotating 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 figure) manually or by a slide base drive mechanism (not shown), the roller 11 rotates. Lever 1
0 and rotate it clockwise to move the slide lever 8 backward against the spring 9.

Then, first, the upper guide pin 5 of the front door slides in the direction of arrow A along the guide groove 7, the upper end of the front door moves away from the top plate, and then the upper and lower guide pins 5 and 6 slide in the direction of arrow B. 2, the front door 4 rotates and rises to the horizontal position shown in FIG.

When the slide base 2 is further moved forward, the roller 11 moves while contacting the lower side of the rotary 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 opening and closing the front door in conjunction with the forward and backward movement of the slide base, the player can be put into use or stored by simply taking the slide base in and out, and it is also possible to put the player into use or storage without having to open the front door. This has the unique effect of making it easier to change records and operate the tone arm because the player does not have to be pulled into the cabinet.
