Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door structure for a record player, and more particularly to a door for an insertion slot of a record player in which a record disc is inserted into the record player together with the record protective case.

In a record player using a record protective case, such as a video disk player, a housing 1 is provided with an insertion slot 2 into which a record protective case 3 is inserted, as shown in FIG.

Conventionally, as shown in Figures 2 and 3, a door 4 was installed after the insertion slot 2.
, and the door 4 is supported by the door stays 5 and 6 at pivot points 7 and 7.
It is held rotatably around the

A guide 8 for holding the inserted record protection case 3 is provided at the rear of the door 4, and the door 4 is pressed in the direction of closing the insertion slot 2 by a spring (not shown).

When the record protective case 3 is inserted into the housing 1 through the insertion slot 2, the tip of the record protective case 3 presses the door 4, and the door 4 rotates around the pivot points 7, 7, and slides inside the housing 1. Then, the record protection case 3 is inserted along the guide 8 as shown in FIG.

In this case, it is necessary that the door 4 does not come into contact with the guide 8 when it rotates, and therefore it is necessary to provide a space between the outside of the housing 1 and the guide 8 for the rotation of the door 4. In other words, when the record protective case 3 is completely inserted into the housing 1, the size of the record protective case 3 remaining outside the housing 1 becomes small, resulting in a disadvantage that there are fewer parts to grip with the hand.

An object of the present invention is to provide a door structure for a record player that eliminates the drawbacks of the prior art described above.

Since the conventional door rotates in the direction toward the inside of the housing, it was necessary to provide sufficient rotation space between the insertion port and the guide.

According to the present invention, by changing the position of the rotation fulcrum of the door, the door moves downward when it rotates, and when the record protection case is inserted from the insertion slot, the inclined piece comes into contact with the record protection case before the door. is provided at an angle to the door surface, and when the record protective case is moved horizontally toward the insertion slot, the door fixed to the inclined piece rotates and moves downward with respect to the insertion slot. Similarly, the door can be opened and closed simply by inserting the record protection case through the insertion slot.

In other words, since the door moves vertically when opening the insertion slot, the gap between the door and the guide can be made significantly narrower than when the door rotates inward, allowing the record protection case to be completely inserted into the housing. Even if the record protection case is inserted into the housing, the external force end of the record protection case can be made to sufficiently protrude outside the casing, and a gripping margin can be secured.

FIG. 5 shows an external view of a preferred embodiment of the present invention, and FIG.
The figure shows the door structure inside the housing 1.

Further, FIGS. 7 and 8 show a BB cross section and a CC cross section in FIG. 5.

An insertion opening 2 for inserting a record protection case 3 is formed in the housing 1, and a door 4 for closing the insertion opening 2 is arranged inside the housing 1.

The door 4 has an S′ U-shape in a plan view, and the door stay 5, is rotatable by pivot points 7, 7 at the tips of the U-shape.
6, and the door stays 5 and 6 are fixed to the housing 1.

An inclined piece 9 is fixed to the door 4, and the inclined piece 9 is inclined outward from the insertion opening 2 and downward.

The door 4 is pressed by a spring (not shown) to the position shown in FIG. 6, that is, to the position where the insertion opening 2 is closed.

A notch 10 is provided in the casing 1 from the outermost periphery to the inside and within a range that does not contact the door 4, at a position where the inclined piece 9 of the door 4 is not present.

In the illustrated embodiment, the door 4 is spaced inward by the amount by which the inclined piece 9 projects so as to allow the door 4 to rotate downward relative to the insertion opening 2; By providing a notch, it can also be provided closely to the insertion port 2.

When inserting the record protection case 3 into the housing 1, Figure 9~
When the record protective case 3 is moved horizontally toward the insertion slot 2 as shown in FIG. is given a downward component of force, the door 4 rotates downward about the rotation fulcrum 7, and when the record protection case 3 is subsequently moved horizontally, the door 4 is moved downward from the record protection case 3 as shown in FIG. Insertion port 2 in contact with the bottom surface
When the record protection case 3 is in the open position, it is stored in the guide 8.

The door 4 rotates around the fulcrum 7, but by appropriately selecting the position of the fulcrum 7, the rotation space of the door 4 can be made small, and the distance between the door 4 and the guide 8 can be narrowed. be able to.

As shown in FIG. 12, since the distance between the door 4 and the guide 8 can be narrow, by forming the notch 10 in the housing 1,
The record protection case 3 can be positioned sufficiently outside the housing 1, and the gripping distance can be increased compared to the conventional system.

Claims (1)

[Scope of Claim for Utility Model Registration] In a record player configured to be inserted into the record player together with a record protection case containing the record disc, an insertion slot for the record protection case on the front of the housing of the record player. A rotatable door is provided at the rear of the insertion port so as to close the insertion port under normal conditions. A record protective case is provided, in which an inclined piece having a protruding inclined surface is fixed to the front surface of the door at a position where the insertion opening is closed, and a notch is provided approximately in the center of the insertion opening to make it easy to grasp the record protective case. When inserting the record protection case through the insertion slot, the inclined piece fixed to the door contacts the record protection case, and the door rotates downward relative to the insertion slot, allowing the record protection case to be inserted into the housing.
