Therefore, by adopting a control system for the image control work recording device 61, the load data should store the size and frequency of occurrence of the load, the state at the time of the overload should be stored as reproducible data, operation and release information of the safety device Data such as to individually store the data may be stored, and specific record items for the data are as described in Table 1 below.

The above data can be printed by an output device (PC, printer, etc.) by providing an external output terminal, and taking appropriate measures to protect the recorded data from being modified again, the memory of the job recording device is located at the place of the job recording device installation. It must be observed that it has the necessary durability for its environment.

[Table 1]

On the other hand, on the inner and outer surfaces of the first to fourth camera devices 20, 30, 40, 50, an antifouling coating layer coated with a composition for antifouling coating is formed so as to effectively prevent adhesion and removal of pollutants. Can be.

The anti-fouling coating composition contains mercaptobenzothiazole and amidoalkyl betaine in a molar ratio of 1:0.01 to 1:2, and the total content of mercaptobenzothiazole and amidoalkyl betaine is 1 with respect to the total aqueous solution. ~10% by weight.

The mercaptobenzothiazole and amidoalkyl betaine are preferably 1:0.01 to 1:2 as a molar ratio.If the molar ratio is out of the above range, the coating property of the substrate decreases or the surface moisture adsorption increases after application. There is a problem that the film is removed.

The mercaptobenzothiazole and amidoalkyl betaine are preferably 1 to 10% by weight in the total aqueous solution of the composition, and if it is less than 1% by weight, there is a problem that the coating property of the substrate is deteriorated, and if it exceeds 10% by weight, the coating film thickness Crystal precipitation is likely to occur due to an increase in

On the other hand, as a method of applying the present antifouling coating composition onto a substrate, it is preferable to apply it by a spray method. Further, the thickness of the final coating film on the substrate is preferably 550 to 2000Å, more preferably 1100 to 1900Å. If the thickness of the coating film is less than 550 Å, there is a problem of deterioration in the case of high-temperature heat treatment, and if it exceeds 2000 Å, crystal precipitation on the coated surface is liable to occur.

In addition, the present antifouling coating composition may be prepared by adding 0.1 mol of mercaptobenzothiazole and 0.05 mol of amidoalkyl betaine to 1000 ml of distilled water, followed by stirring.

When the safety cover 300 is made of metal, benztriazole 15% by weight, ethylene glycol butyl ether 25% by weight, hafnium 20% by weight, molybdenum emulsified (MoS ² ) 10% by weight, titanium oxide to prevent corrosion of the metal surface (TiO ² ) It is composed of 15% by weight and 15% by weight of phenol noblock glycidyl ether, and a surface coating layer formed with a coating thickness of 8 μm can be formed.

Benztriazole, ethylene glycol butyl ether, and phenol noblock glycidyl ether play a role in preventing corrosion and discoloration.

Hafnium is a transition metal element with corrosion resistance and plays a role in having excellent waterproof and corrosion resistance.

Molybdenum emulsified plays a role of imparting wetness and lubricity to the surface of the coating film.

Titanium oxide is added for the purpose of fire resistance and chemical stability.

The reason why the ratio of the constituent components and the coating thickness were numerically limited as described above was analyzed through the test results while repeatedly failing by the present inventors, and as a result, the optimum anti-corrosion effect was exhibited at the ratio.

A vibration absorption prevention part of a rubber material may be further installed at the lower ends of the first to fourth camera devices 20, 30, 40, 50. The ratio of the raw material content of the vibration-absorption preventing part is mixed with rubber 60% by weight, carbon black 33 to 36% by weight, antioxidant 2 to 5% by weight, and sulfur as an accelerator 1 to 3% by weight.

Carbon black is to increase abrasion resistance, so it is added, but if the content is less than 33% by weight, elasticity and abrasion resistance decrease, and if it exceeds 36% by weight, the content of rubber, which is a main component, is relatively small, and elasticity may decrease. , 33 to 36% by weight are mixed.

Antioxidant is 3C (N-PHENYL-N'-ISOPROPYL- P-PHENYLENEDIAMINE) or RD (POLYMERIZED 2,2,4-TRIMETHYL-1,2-DIHYDROQUINOLINE) to add 2 to 5% by weight, 2 If it is less than% by weight, the product is easily oxidized, and if too much is added and exceeds 5% by weight, the content of the rubber, which is the main component, is relatively small, and the elasticity may be lowered. ~5% by weight is appropriate.

Sulfur as an accelerator is mixed with 1 to 3% by weight. If less than 1% by weight, the vulcanization effect in the heating process during molding is insignificant, so 1% by weight or more is added. If it exceeds 3% by weight, since the content of the rubber as the main component is relatively small, the elasticity may be lowered, so 1 to 3% by weight is appropriate.

Therefore, since the present invention is reinforced with synthetic rubber having elasticity in several directions, the elasticity, toughness and rigidity of the first to fourth camera devices 20, 30, 40, 50 are increased, so that durability is improved. The life of the belt 93 is increased.
