Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a recording / reproducing apparatus such as a disc player such as a CD, an LD, a CD-ROM or a video tape recorder, and in particular, an insertion port for a disc, a cartridge or a cassette. Related to the mechanism of the door.

(B) Conventional technology For example, conventionally, a disk player such as a CD, LD, or CD-ROM has a disk or cartridge provided on the front panel (12) of the device body (10) as shown in FIG. A so-called front loading system in which a disc or a cartridge is loaded from the insertion port (15) of is generally used.

Since such a device prevents dust and the like from entering the main body of the device through the insertion opening (15), the insertion opening (15) has been different from the conventional one.
A rotatable door (11) having a rotation fulcrum is provided on the left and right upper edges of the. As shown in FIG. 8, the combination of the door (11) and the front panel (12) is such that the rotating shafts (11b) (11b ') provided at both ends of the door (11) are connected to the front panel (1).
2) Holes (13a) (13) provided in the side walls (13) (13 ')
It was done by fitting to a ').

(C) Problems to be Solved by the Invention However, in the conventional door mechanism, the gap between the restricting portions (11c) and (11c ′) for preventing the door (11) from being displaced in the axial direction has a front panel (12). ) Is almost the same as the space between the side walls (13) and (13 '), so the door (11) is attached to the front panel (12).
The door (11) is bent or the side wall (13) (1
I was pushing the space between 3 '). Therefore, an unreasonable force is applied to the parts, which causes damage to the parts and increases the burden on the operator.

It is also conceivable to form the rotating shaft parts (11b) (11b ') of the door (11) separately from the door (11), but this is not preferable because it causes an increase in the number of parts and an increase in the number of work steps. .

The present invention has been made in view of such circumstances, and is intended to reduce the labor and the damage rate of parts.

(D) Means for Solving the Problems The recording / reproducing apparatus of the present invention is provided with a flap portion, a rotary shaft projecting from both ends along the upper side of the flap portion, and one of the rotary shaft and the flap portion. A door formed of a first protrusion formed so as to project downward from the upper side of the flap without protruding upward at the boundary of the flap, an insertion port covered by the door, and the rotating shaft are inserted. A front panel having a side wall having a hole, and a second protrusion provided in the vicinity of the hole and the side wall only below the position of the hole; and The door is rotatably attached to the front panel by fitting and positioning the first protrusion inside the second protrusion with respect to the side wall.

(E) Action The door is rotatably supported by the front panel by fitting the rotary shaft of the door into the hole of the front panel. The door has the first protrusion of the door and the second protrusion of the front panel. The part restricts the insertion of the turning shaft into the hole and the movement of the door in the axial direction. That is, the first protrusion and the flap of the door are positioned above the rotary shaft, and one rotary shaft is inserted into the hole. At this time, since the first protrusion and the second protrusion do not engage with each other, the rotary shaft can be inserted deep into the hole. Next, the other rotating shaft is inserted into the hole. Next, the door is rotated so that the first protrusion and the flap are below the rotation shaft. At this time, the first protrusion and the second protrusion are engaged with each other, and the movement of the door in the axial direction is prohibited.

(F) Embodiment FIG. 7 is an external perspective view showing a disc player such as a CD, LD or CD-ROM adopting the present invention. The disc player comprises a cover body (4) for enclosing the entire player and a front panel (2), and the front panel (2) has an insertion port (5) for loading a disc or a cartridge and the insertion port (5). There is a door (1) covering it.

FIG. 1 is an exploded perspective view showing a back side of a door mechanism portion of a disc player of the present invention.

The door (1) includes a flap portion (1a) that covers the insertion opening (5) of the front panel (2), a rotation shaft (1b) (1b ′) that serves as a rotation fulcrum of the flap portion (1a), Protrusions (1c) (1c ') are formed to prevent the door (1) from moving in the axial direction. The protrusion (1c) (first protrusion) is formed on the side where the flap (1a) is formed without protruding from the upper side of the flap (1a).

The front panel (2) has a rotating shaft (1b) for the door (1).
The door (1) is engaged with the side walls (3) and (3 ') having holes (3a) and (3a') into which (1b ') is fitted, and the protrusions (1c) and (1c') of the door (1). ) Is provided with protrusions (second protrusions) (2b) (2b ') for preventing the movement of (1) in the axial direction.
Then, the protrusion (2) with which the protrusion (1c) of the door (1) engages
b) is formed only below the hole (3a).

2 to 6 show a door (1) and a front panel (2).
FIG. 2 (a) is a view of the door mechanism of the present invention seen from the rear (hereinafter referred to as rear view), and FIG. 2 (b).
Is a UU sectional view of FIG. 2 (a), FIG. 3 (a) is a rear view,
3 (c) is a VV sectional view of FIG. 3 (a), FIG. 4 (a) is a rear view, FIG. 4 (b) is a XX sectional view of FIG. 4 (a), and FIG. c) is a cross-sectional view taken along the line X'-X 'of FIG. 4 (a), FIG. 5 (a) is a rear view, FIG. 5 (b) is a cross-sectional view taken along the line YY of FIG. 5 (a), and FIG. 5C is a cross-sectional view taken along the line Y′-Y ′ of FIG. 5A, FIG. 6A is a rear view with the cover body 4 attached, and FIG. a)
ZZ sectional view, FIG. 6 (c) is Z′-Z ′ of FIG. 6 (a)
FIG.

First, the step of attaching the door (1) will be described with reference to FIGS. 2 to 4.

First, with the flap (1a) and the protrusion (1c) of the door (1) positioned above the rotary shaft (1b), the rotary shaft (1b)
Is inserted into the hole (3a) of the side wall (3). At this time, the protrusion (1c) and the flap (1a) of the door (1) and the protrusion (2b) of the front panel (2) do not come into contact with each other, so that they can be inserted up to the base of the rotating shaft (1b). (Fig. 2).

Next, the rotary shaft (1b ') is inserted into the hole (3a') until the protrusion (1c ') of the door (1) abuts the protrusion (2b') of the front panel (2). By this, the mounting position of the door (1) is determined (Fig. 3).

Finally, the flap portion (1a) and the projection portion (1c) of the door (1) are rotated so as to be located below the rotation shaft (1b) (fourth).
Figure).

The door (1) can be attached by such a series of operations.

Next, the rotation range of the door (1) will be described with reference to FIGS. 5 and 6.

In actual use, the rotation angle of the door (1) when inserting a disk or a cartridge into the opening (5) of the front panel (2) is about 90 ° at the maximum, and within this range, the door (1) is rotated. Since the engagement between the protrusion (1c) and the protrusion (2b) of the front panel (2) is not released, the door (1) does not move in the axial direction.

FIG. 6 shows a rear view with the rear cover (4) attached. The top plate portion of the cover body (4) restricts upward rotation of the flap portion (1a) and the protrusion portion (1c) of the door (1), and the protrusion portion (1c) of the door (1) and the front panel. (2
It will not disengage from b).

(G) Effect of the Invention According to the present invention, since the door can be installed without difficulty, it is possible to reduce the work labor and the damage to parts, and it is possible to realize a door device having high industrial utility value.
