Description

[Detailed Description of the Invention] The present invention relates to a cabinet with a dust cleaning device that can easily clean dust accumulated around a dial scale plate, etc. in a cabinet for electronic equipment such as a cassette tape recorder with a radio.

To explain in more detail, the present invention makes it possible to clean the assembled parts without disassembling them one by one.
The purpose is to provide a cabinet for electronic equipment that can improve serviceability.

First, a conventional tape recorder with radio will be explained with reference to FIGS. 1 to 5.

In FIG. 1, FIG. 1a shows a chassis assembly, and FIG. 1 shows a cabinet assembly, and FIG. 1 is a perspective view when the chassis assembly is disassembled from the cabinet assembly.

1 is a cabinet, 2 is a transparent plate made of synthetic resin that is glued to the cabinet, 3 is a chassis, 4 is a dial scale plate that is glued to the chassis, 5 is a slidable pointer built into the chassis, 6 is dust that has accumulated at the bottom of the front of the dial.

Although the explanatory diagram is extreme, the dust that has accumulated as shown in FIG. 3 can be easily removed with a hand towel 7 by separating the chassis assembly from the cabinet assembly as shown in FIG.

However, when adopting a chassisless structure as shown in Figure 4, the only way to remove accumulated dust is to remove the front transparent plate 2. This is fine if it can be removed easily, but it creates another problem. Easy to occur.

The present invention aims to propose a cabinet that can solve this problem.

That is, in the present invention, as shown in Fig. 6.7.8.9, an air blowing hole (nozzle) 8 is provided near the edge of the synthetic resin cabinet 1.
are provided, and are communicated via communication holes 9 to four large and small gaps 10 in which dial scales 4 and pointers 5 are housed.

Further, a dust discharge hole 11 is provided in the other side of the narrow gap portion 10.

Then, air is blown in forcefully from the air blowing hole 8 to easily remove dust from the dust discharge hole 11.

The structure of the air blowing nozzle 8 shown in Fig. 6.7.8 is such that when molding a synthetic resin cabinet, a tapered hole 8a that expands toward the mold core (not shown) is opened to form a cavity (not shown). A semicircular communication hole 9 is provided on the cavity side as shown in the cross section of FIG. 7, so that the nozzle can be directed in any direction as shown in FIG.

This nozzle portion 8 is hidden by painting or hot stamping the periphery of the transparent plate 2 attached to the front surface, and is provided at a position that cannot be seen from the front surface of the set.

The dust discharge hole 11 is a hole formed by the sides of the mold cavity side and the core side, and is also hidden in the paint or hot stamped area around the transparent plate 2, and is provided in a position where it cannot be seen. It passes through and comes out to the core side.

In FIG. 10, A is a diagram in which an air gun fitting positioning rib 13 is provided on the outer periphery of the nozzle 8 so that an air gun or the like can be applied at the set manufacturing factory.
1 is a diagram showing a person placing a straw 14 for drinking juice or the like against the nozzle 8 when cleaning work at a store or the like.

Since the nozzle 8 is tapered, the straw 14
It absorbs variations in thickness, such as thick or thin, and can be used with any.

In this way, with the device of the present invention, it is possible to clean the dial part without removing any parts from the cabinet assembly, making it easier to service than with conventional chassis assemblies. , service performance will be significantly improved.
