BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a merchandise processing apparatus, such as an electronic balance or a cash register, for processing merchandise for food.

[0002]

2. Description of the Related Art Conventionally, some commodity processing apparatuses such as an electronic balance take measures against pests such as cockroaches (for example, Japanese Patent Application Laid-Open No. 9-189597). This is shown in FIG.

[0003] In an exploded perspective view of FIG.
, A substantially closed space is formed between the main body case 101 and the weighing dish 102. In addition, since the lower part of the weighing dish 102 has excessive heat and is warm even in winter, cockroaches and the like easily enter. Further, since the weighing pan 102 is supported by a load cell provided inside the main body case 101, there is an intrusion path 103 communicating with the inside of the lower part of the weighing pan 102. 1
01 may enter.

Therefore, in the prior art, a main body case 10 is provided.
1 on the opposing surface 104 of the weighing pan 102,
Pest repellent is applied to the shaded area. According to this prior art, it has been reported that cockroaches are less likely to enter the main body case 101 as compared with those without any pest control (the same publication).

[0005]

However, in the above prior art, cockroaches are less likely to enter the main body case 101 as compared with those without any pest control measures. However, there is still a problem that the cockroaches enter the main body case 101 and form a nest. Thus, when the cockroach enters the main body case 101, a short circuit of the wiring board or the power supply occurs, or each component is damaged.
In particular, it is unsanitary in a product processing apparatus that handles food.

On the other hand, it is conceivable to close the invasion path 103 by using a diaphragm, as in a waterproof electronic balance. However, in this case, a mechanism for removing the influence of a change in the atmospheric pressure or the like is required, which causes an increase in cost.

[0007] Accordingly, an object of the present invention is to prevent a pest such as a cockroach from entering a product processing apparatus and arriving or forming a nest without incurring a considerable increase in cost.

[0008]

In order to achieve the above object, the present invention relates to a product processing apparatus for processing a food product, wherein at least an inner layer of a case of the product processing apparatus or at least a surface of a wiring board is provided. The layer is provided with a pest repellent layer containing a pest repellent.

According to the present invention, since the pest repellent is provided on the inner layer of the case and the wiring board, even if a pest such as a cockroach enters the case, the cockroach or the like can settle or settle in the case. There is no danger. In addition, since a pest repellent that repels cockroaches and the like instead of killing them is used, there is no possibility that the cockroaches or the like will die inside the device.

In particular, the pest repellent layer is preferably provided on a surface facing the wiring board or other heat source. The pest repellent layer may be provided at least on a part of the case or the wiring board. As a method of providing a pest repellent, in addition to a method of applying a coating agent containing an active ingredient for repelling insects to the inner surface of the case or the surface of the wiring board, or attaching a tape or sheet, the case or the wiring board may be used. There is a method in which a pest-repelling active ingredient is contained in a resin that forms the resin.

As the insect repellent used in the present invention, those generally used as insect repellents such as cockroaches can be used. For example, N, N-diethyl-m-toluamide, N-butylacetanilide, N, N-diethylsuccinamate and the like.
