BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video tape recorder, an audio tape recorder, a digital audio recorder or an optical disc or a compact disc for recording and / or reproducing by mounting a record carrier such as a video tape cassette or an audio cassette. The present invention relates to a recording / reproducing device such as a disc player for mounting a record carrier for recording and / or reproducing, and more particularly to a structure of a door for inserting a record carrier.

[0002]

2. Description of the Related Art Conventionally, there is a recording / reproducing apparatus in which a door is attached to the front side of a deck chassis on which a video tape cassette is mounted and supported, and the door is attached to a front plate of a record carrier insertion port so as to be freely opened and closed. FIG. 5 is a sectional view of an essential part showing an example of the structure of a conventional door. Bearing ribs, which are supports, inside the front plate (38) of the deck chassis
(39) is provided, and the door axle (3
1) is provided, and the door shaft (31) is rotatably inserted into the bearing rib (39), so that the front plate (38) is fitted to the door (37).
Is installed.

Further, an ear piece (47) is integrally formed on one side of the door (37), and a video tape recorder unit (35) is formed.
By engaging the pin (48a) at the tip of the door opening / closing arm (48) provided in the ear-shaped piece (47) and rotating the door opening / closing arm (48) in the direction A by a motor (not shown), (3
This is to open 7) to the position of the chain double-dashed line.

[0004]

However, in the structure of the conventional cassette door (37) described above, the video tape recorder unit (35) is mounted on the deck in the direction of the arrow (B) in the assembly process such as the production process or the maintenance process. As shown by the chain double-dashed line in Fig. 5, when installing the door (3) so that the door opening / closing arm (48) does not hit the ear piece (47),
Since it was necessary to assemble 7) in an open state by hand or a jig, the work was complicated and productivity was poor, and it also hindered mechanization of the process. Further, if the door (37) is assembled in a closed state by mistake, there is a possibility that trouble such as damage to the ear piece (47) may occur.

Therefore, the present invention has been made in view of the above circumstances, and an object thereof is to provide a door in which a video tape recorder unit can be easily incorporated in a video tape recorder or the like.

[0006]

In the above-described recording / reproducing apparatus, the present invention provides the door opening / closing arm on the side portion of the door when the door is operated in the opening direction. A guide means for retracting the door outward along the direction is provided.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 is an exploded perspective view showing only an essential part of a video deck according to the present invention. It is a front of a deck chassis (2) to which a video tape recorder unit (1) is fixed and a deck chassis before assembly. The face plate (3) is shown. The opening / closing door (5) is located on the door slot (4) of the cassette opened on the front plate (3).
It is rotatably supported around (6), and the door opening / closing arm is attached to the video tape recorder unit (1) as described above.
(7) is provided.

The door opening / closing arm (7) is swung up and down like a conventional one by a motor (not shown) mounted on the video tape recorder unit (1), but the door opening / closing arm (7) of this embodiment is made of resin. It is a product and has some flexibility. Reference numeral (7a) is an engagement pin for a door provided at the end of the arm (7).

As described above, the opening / closing door (5) is rotatably supported by the bearing ribs (not shown) provided on the front plate (3) with the door shaft (6) integrally molded on both upper ends of the cassette, and the cassette is opened. Insertion slot
It swivels between a vertical position that closes (4) and a substantially horizontal inclined position that opens the cassette insertion opening (4) almost entirely.

On the side of the door opening / closing arm (7) side of the opening / closing door (5), there is formed an ear-like portion (8) protruding into the swing locus of the door opening / closing arm (7). Yes, this ear (8)
A guide portion (9) according to the present invention is provided on the back side of the.

That is, as shown in FIG. 1, in this embodiment, a triangular pyramid-shaped guide portion (9) is integrally formed on the back surface of the ear-shaped portion (8) so that its slope (9a) faces substantially upward. It is molded. And the lower end (9b) of the slope (9a) of this guide part (9) is an ear-shaped part.
It is formed on the same surface that is continuous with the end surface (8a) of (8).

Since this embodiment has the above-mentioned structure, when the front plate (3) of the chassis is assembled to the deck chassis (2), the ear-like portion (8) of the door opening / closing arm (7) is It is not necessary to assemble the door (5) with the hand or jig open to prevent it from hitting the pins (7a) .The door (5) should remain vertically closed and the front plate (3) and deck should be closed. It suffices to assemble the chassis (2), and the pin (7a) of the door opening / closing arm (7) is once assembled on the rear side of the door ear-like portion (8).
When an operator or a worker inserts the cassette through the insertion opening (4) or manually opens the door (5) after assembling, the pin (7a) of the door opening / closing arm (7) is guided by the guide portion (9). It moves around in front of the door (5).

That is, as shown in FIGS. 1 (a) to 1 (c), when the door (5) begins to open, the pin (7a) abuts against the slope (9a) and the ear-like portion is formed. It is guided in the direction of the end face (8a) of (8) (that is, in the direction away from the ear-like portion (8)). When the door (5) continues to move in the opening direction, the pin (7a) turns into a slope (9a).
To the lower end (9b) of the ears, and then transfer to the end face (8a) of the ear-like portion (8). Finally, the pin (7a) is attached to the end surface (8
Go over a) and go to the front.

During the above operation, the door opening / closing arm (7) is forced to swing in the direction of the door shaft (6) (horizontal direction) orthogonal to the original swinging motion. This is allowed by the flexibility of the opening / closing arm (7) itself. However, the means for allowing the door opening / closing arm (7) to move in the door axial direction is not limited to the door opening / closing arm (7) itself made of flexible resin as described above, but the door opening / closing arm (7) is also included. Swivel axis (7
Various modifications can be made such as b) having a structure capable of sliding along the axis (7b) direction.

Further, the shape of the guide portion (9) is not limited to the triangular pyramid shape, and may be a slope plate (10) as shown in FIG. 3 or an ear-like portion (8) as shown in FIG. It may be the groove (11) formed in the above.

[0016]

As described above, the recording / reproducing apparatus according to the present invention does not require the extra operation at the time of assembly as described at the beginning, and can be easily assembled and mechanized.
