DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette holder in a cassette type recording/reproducing apparatus using a tape cassette.

Cassette type recording/playback device, e.g. cassette type
In a VTR, an opening is provided on the top surface of the cabinet, and a cassette holder is movably mounted within this opening. Then, when the tape cassette is inserted into the cassette holder in the non-operating position protruding from the opening of the cabinet and the cassette holder is lowered and moved to the operating position, the tape cassette in this cassette holder is loaded into the loading position. That will happen. At this time, the opening of the cabinet is closed by the decorative plate of the cassette holder. Even when not in use, the cassette holder is lowered and moved into the operating position, so that the opening of the cabinet is covered by a decorative laminate to avoid unsightly appearance.

In order to attach such a decorative board to a cassette holder, conventionally, a female screw hole is formed in the frame of the cassette holder, and a through hole with a large clearance into which a screw is loosely fitted is formed in the decorative board. The screws inserted through the frame were engaged with female threaded holes in the frame to secure the frame. During this fixing, the position of the decorative board is adjusted in the direction of its surface by the clearance between the through hole and the screw, so that the clearance between it and the opening of the cabinet is almost constant in all directions. Ta. Furthermore, a recess is formed in the decorative board to receive the head of the screw, so that the head of the screw does not protrude from the outer surface. Therefore, when the decorative plate is adjusted in position relative to the opening of the cabinet, the screws become biased with respect to the center of the recessed portion, resulting in an unsightly and unsightly appearance.

The present invention has been developed in view of these problems, and it allows the position of the decorative plate to be adjusted with respect to the opening of the cabinet, and also allows screws for fixing the decorative plate to the frame of the cassette holder to be fixed to the decorative plate. It is designed so that it can be placed at a predetermined position with respect to the board.

An embodiment in which the present invention is applied to a VTR cassette holder will be described below with reference to the drawings.As shown in FIG. A large rectangular opening 3 is formed near the . A cassette holder 4 is housed within this opening 3.

Ru. Then, the magnetic tape is pulled out from the tape cassette and wound around the head drum to perform recording and reproduction.

The decorative board 5 is molded from synthetic resin and has approximately the same shape and size as the opening 3 of the cabinet 1. A horizontally elongated opening is formed in the center, and a window is formed by attaching the transparent plate 9 to this opening. This window allows the status of the tape cassettes in the cassette holder 4 to be observed from the outside. Furthermore, a pair of circular recesses 10 are formed on the left and right sides of the upper surface of the decorative board 5 at positions that are biased towards the back side (see FIG. 3). This recess 10 is for receiving the head of a screw 11 for fixing the decorative board 5 to the frame 6 so as not to protrude above. A smaller through hole 12 is formed in the center of the recess 10. The screw 11 is inserted into the through hole 12, and the diameter of the through hole 12 is approximately equal to the diameter of the shaft portion 13 of the screw 11, so the clearance between the two is very small. It's summery. Furthermore, on the lower surface of the front side of the decorative board 5,
A pair of claws 14 are integrally provided on the left and right sides. These claws 14 are adapted to engage with ribs 15 (see FIG. 4) formed on the front side of the frame 6.

On the back side of the frame 6, there are a pair of protrusions 1 on the left and right.
6 are formed, and these protrusions 16 have a third
As shown in the figure, a through hole 17 is formed corresponding to the through hole 12 of the decorative board 5. The threaded portion 18 of the screw 11 is inserted into this through hole 17, and the diameter of the through hole 17 is equal to the threaded portion 18.
, and a large clearance is formed between the two. Further, the protruding piece 16 has cutouts 19 and 20 formed at its tip and side, respectively. Furthermore, the protrusion 16
A rectangular small hole 21 is formed at the base side of the hole.
Further, as shown in FIG. 3, the nut plate 22 attached to the lower surface of the protruding piece 17 is made of a small metal plate, and has a female threaded hole 23 formed approximately in the center thereof. Further, a bending piece 25 having a pair of arms 24 is connected to one end thereof, and a bending piece 26 is formed at the other end. Further, a locking piece 27 is formed on one side thereof.

Next, in the cassette holder 4 as described above,
The operation of attaching the decorative board 5 to the frame 6 will be described. First, the nut plate 22 is attached to the protrusion 16 of the frame 6. For this installation, the nut plate 22 is tilted upward to the left as shown by the chain line in FIG. 4, and the bent piece 26 is inserted into the small hole 21 of the projecting piece 16. Then, the nut plate 22 is rotated as shown by the arrow, and the arm 24 is moved past the tip of the protrusion 16 to a position corresponding to the upper surface thereof. Next, the nut plate 22 is moved to the left so that the arm 24 is placed above the protrusion 16 and the bent piece 25 is inserted into the notch 19. Next, the tip of the locking piece 27 is bent and the tip is inserted into the notch 20. This prevents the nut plate 22 from moving more than a predetermined stroke to the right in FIG. 4, and prevents the nut plate 22 from falling off the protrusion 16. The bent pieces 25, 26 and the locking piece 27 are connected to the notch 19, the small hole 21 and the notch 2.
