In the known art, a panel door structure is disclosed as an opening / closing means, which is disposed on a front surface of a tray and is rotatably opened and closed relative to a panel in association with the tray.

1 is a side sectional view showing an embodiment of a panel door structure of a conventional video reproducing / recording apparatus.

As shown in the drawing, the conventional panel 30 door 10 has a door 10 in which a door arm 12 having a hinge pin 14 is integrally formed, a spring 20 extending at both ends, and a plurality of doors 10. Bracket 32 and the locking piece 32a includes a panel 30 formed integrally.

The door 10 generally has a rectangular shape that is generally elongated in the transverse direction along the front shape of a tray (not shown) in which the storage medium is accommodated, the door arm 12 having an inner hook shape is integrally formed, and the door arm ( 12 has a hinge pin 14 and a through hole protruding outward.

The panel 30 has an opening corresponding to the shape of the door 10, and a plurality of brackets 32 and a locking piece 32a are formed in the inner side adjacent to the opening, and the bracket 32 is a spring 20. The fitted hinge pin 14 is provided with a through hole for insertion.

The operation of the panel door structure of a conventional video reproducing / recording device having such a configuration is as follows.

The opening of the panel 30 is always closed by the door 10, and the door 10 rotates and opens with respect to the panel 30 only when the tray is unloaded for seating or withdrawing the medium.

When the medium is seated, the inner surface of the door 10 is pressed by the front side of the tray as the tray is ejected through the opening of the panel 30, and the door 10 rotates about the hinge pin 14 Open.

The hinge pin 14 is rotatably inserted around the through hole of the bracket 32 while the spring is inserted. One extension end of the spring 20 is supported by the door arm 12, and the other extension end is By being caught by the catching piece 32a or the bracket 32 or in direct contact with the inner surface of the panel 30, the door arm 12 of the door is elastically restrained against the inside of the panel 30, and the door 10 The larger the angle of rotation, the greater the restoring force.

While the tray is unloaded, the door 10 is supported by the tray in a pressure-up state. As the tray is inserted after the medium is seated and removed, the door 10 is returned to its initial position by the elastic restoring force of the spring 20. Thus, the opening of the panel 30 is closed.

The panel door structure operating as described above hinges the spring 20 on the hinge pin 14 of the at least one door arm 12 and inserts the door arm 10 through the opening of the panel 30 to hinge. After arranging the pin 14 to approach the bracket 32, first, the hinge pin without the spring 20 is inserted through the bracket 32, and then the hinge pin 14 with the spring 20 inserted therein. Is assembled by inserting through the through-hole of the bracket (32).

However, in general, the spring 20 is mounted only on one side of the door arms 12 on both sides of the door 10, and thus, the spring 20 is mounted on the panel 30, and then the door 10 has one side by an elastic force applied from the spring 20. Eccentricity is generated, and even in a structure in which the elastic member acts only on one side of the door 10 at a portion where the door 10 and the panel 30 are hinged, even when the elastic member is not the same as the spring 20, The occurrence of eccentricity causes structural deformation by generating a torsional stress inside the door 10, and furthermore, such deformation is coupled to the hinge pin 14 of the door arm 12 through the through hole of the bracket 32. Also, the hinge pin 14 is easily detached from the through hole of the bracket 32. In order to prevent such eccentricity, when the spring 20 is mounted on both sides, the spring pin, which is a small elastic body, is precisely handled and mounted. Sun Group because the difficulty of the process and the weight, and thus the process efficiency is lowered, and had a problem in that the manufacturing cost increases.

The present invention is to solve the above-mentioned conventional problems, an object of the present invention is that the door is supported from one side of the elastic member is eccentric, which causes deformation in the long term, and also elastically separated and lost due to external impact The present invention provides a panel and a door for an electronic device having a structure in which a door arm is coupled to prevent separation and detachment with respect to a panel bracket.

The present invention for realizing the above object is a panel having an opening and having a bracket, a door having a door arm coupled to the bracket so as to open and close the opening rotationally, and an elastic force to return the opening movement of the door. In a panel and door for an electronic device including an elastic member to be exerted, the door arm is provided with an elastic guide pin having a release preventing protrusion formed at an extended end thereof, and the bracket guides the movement of the guide pin but has a length longer than the movement trajectory. While having at least one side is characterized in that the guide hole is provided with a projection insertion hole is formed in a position shifted to prevent the separation prevention projections to be inserted by bending.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

The door arm 12 is hinge pin 14 rotatably inserted into a through hole formed in the bracket 32 for hinge engagement with the bracket 32, and protrudes from the door arm 12 and extends to an extended end. It is provided with the guide pin 16 in which the departure prevention protrusion 16a which has a larger diameter is formed.

The panel 30 is formed with an opening for entering and exiting the tray, and the shape of the opening has a width through which the front surface of the tray can pass and excludes unnecessary free space. The bracket 32 is formed, and the through-hole and the guide pin 16 to which the hinge pin 14 provided on the door arm 12 is rotatably inserted into the bracket 32 and the guide pin 16 are slidably inserted and mounted. The hole 36 is formed.

Guide hole 36 is formed in a circular arc shape on the upper side of the through hole centered on the through hole formed in the bracket 32, the length is a trajectory in which the guide pin 16 to be inserted is rotated in accordance with the rotation of the door Longer than

In addition, at least one side of the guide hole 36 is formed with a projection insertion hole 36a having a larger diameter to match the size of the separation prevention projection 16a formed at the end of the guide pin 16.

Therefore, the guide pin 16 is inserted into the bracket 32 at the same time as the hinge pin 12 is inserted into the bracket 32 when the door 10 is mounted to the panel 30. Since the insertion hole 36a is formed at one end of the guide hole 36 formed longer than the movable trajectory, the release preventing protrusion 16a is formed in the guide hole 36a of the protrusion insertion hole 36a. The guide pin 16 is made of an elastic body so that it can be bent to reach one end of 36.

It can be inserted only through the projection insertion hole 16 formed with a larger diameter in accordance with the shape of the prevention projection 16a. Therefore, the release prevention projection 16a must be slightly bent to be inserted through the projection insertion hole 36a. Can be.

Since the guide hole 36 is formed longer than the trajectory of the guide pin 16, which is rotated together with the rotation of the door 10, the guide hole 36 is guided when the door 10 is mounted on the panel 30. When the pin 16 is slightly bent to pass the release preventing protrusion 16a through the protrusion insertion hole 36a, the guide pin 16 is elastically restored while being inserted into the guide hole 36 to insert the protrusion of the guide hole 36. Slightly spaced from the hole 36a to the center.

The guide hole 36 has a size sufficient to allow the release preventing protrusion 16a to be detached only in the protrusion insertion hole 36a and is formed in a smaller size in other parts, so that the guide pin 16 is completely mounted. When slightly spaced apart from the projection insertion hole 36a of the guide hole 36, the guide projection 16a is caught inside the guide hole 36 inserted into the small opening.                     

As described above, according to the preferred embodiment of the present invention, the guide pin 16 is formed in the door 10 and the guide hole 36 is formed in the bracket 32 of the panel 30, respectively, and the relative movements are prevented from being separated.
