<Prior art and background> If we consider a line printer as an example of a device that generates sound inside a housing, there is a section where unprinted paper is taken in and out, a lid section that is opened when replacing paper or ribbon, and a section where paper is ejected. There are openings, such as exits for storage, and parts that must be opened and closed for storage, and there are always joints in the opening and closing parts, but the sealing of these joints cannot be managed very well, and there may be gaps. There was a problem with the sound leaking easily when it was possible to do so. In addition, to prevent gaps from forming at these joints, elastic auxiliary members such as sponges and magnetic packings are known to close the gaps, but the sound insulation properties of these materials are limited by the plastic material used to form the housing. or,
It is significantly inferior to a metal wall, and there was a problem in that even if you tried to eliminate gaps, sound would leak through the joints and increase the noise level of the equipment.

<Purpose and Features> In view of the above, the present invention was developed while investigating how sound passes through, and discovered that the part of the magnet packing that encloses the magnet inside,
I realized that the part to be glued does not allow much sound to pass through, and that the part in the middle that gives it elasticity is curved, so I used them differently and found that they were compared to a single wide piece. The purpose of this invention is to ensure sound insulation at joints, and the feature of this invention is that it is a means to meet the above objective. As a soundproof joining structure of the opening/closing structure of the housing, an opposing surface made of a ferromagnetic material having a predetermined width is formed around the opening of the housing and a portion of the lid member corresponding to the opening, and the opposing surface is Magnetic packing made of an elastic material that can be bent in the normal direction of the surface and has a magnetic member inside is wrapped around the outer circumferential side and inner circumferential side of the opposing surface on the casing side and the lid side, respectively. To provide a soundproof joint structure between a housing and lid structure, which is attached to the housing lid structure and is characterized in that when the magnetic gaskets are attached to opposing surfaces of each other, a sealed space is created in the middle. .

<Example> Fig. 1 is a general explanatory diagram and a sectional view showing the structure of a commercially available magnetic packing 2, in which a hollow part 2b of extruded synthetic rubber, vinyl, etc.
There is a thin base part 2a with a surface for adhering to the target member under the structure of two stacked parts 2c, and a ferrite magnet is hardened with rubber etc. at the end when viewed from the base, giving it some flexibility. It is constructed by inserting a so-called rubber magnet 1, and when in use, the base part is glued to one member and the magnet part adheres to the other member to form a tight seal, and uneven clearance is caused by the intermediate The structure is adjusted by the bending of the plastic that makes up the outside of the hollow part.

Figures 2 and 3 are explanatory diagrams of one embodiment of the present invention, in which part A and part B of the casing, whose openings abut against each other to form a sealed structure as a whole, are connected by a hinge 3 so as to be openable and closable. This explains the structure in which case A has a full opening and case B has a partial opening, but it seems that at least both cases have a calyx-shaped opposing surface that can face each other around the periphery. The housing A is formed along these calyx-shaped facing portions Af and Bf.
On the side, magnetic seal A 2 is installed along the inner edge of the calyx-shaped surface facing part, and on the case B side, magnetic gasket B 2 is installed along the outer edge of the calyx-shaped surface facing part. When the hinge 1 is closed and the casings A and B are put together, these attached seals will stick to the opposing surfaces without overlapping each other, creating a double seal with an airtight space in the middle. do. The enclosed space in the middle can be used as a place where the heads of screws can be exposed for installing hinges or installing interior items or wall panels inside the housing.

When I tested this configuration by making a joint between the device's housing and testing it, I naturally expected that the sound insulation would be better than with just one magnetic gasket, but I installed two magnetic gaskets in the same direction. It was found that the transmission was several tenths lower than when the housings were used as close together as possible, and when applied to equipment, stable sound insulation could be achieved with less variation due to manufacturing defects between the housings. I found out.

Although this is an afterthought, it is possible that gaps due to poor adsorption of the magnet due to distortion of the other side are dispersed, and that the sound transmitted through the elastic part must be transmitted in an S-shape in the closed space in the middle. I think this is due to the increased number of conversions when the sound passes through air, plastic, and air, but although there is data on the results, the exact answer in a theoretical sense is not known.

しかし現実的に加算以上の効果を生じることは
かなり確かなことと考えられる。
However, it is considered to be quite certain that the effect actually exceeds that of addition.

<Effects> As explained above, according to the configuration of the present invention, it is possible to relatively easily eliminate sound leakage from the housing joints, which is one of the causes of internally generated sound being radiated or leaking to the outside.
Compared to conventional configurations, the sound insulation effect of the sealed casing with a bonded structure can be effectively prevented.
This had the practical effect of being able to lower the noise level by more than 3 dB.
