装置を提供することを目的とする。By the way, when the cargo handling is placed in the refrigerator and a forklift truck goes in and out of the refrigerator to carry out the loading and unloading work, in that case, the temperature difference between the inside and the outside of the refrigerator is increased. Therefore, the screen of the display becomes difficult to see due to dew condensation. Especially, the display is LCD
In this case, since the liquid crystal becomes inoperable at low temperatures, it may not be possible to carry out the loading / unloading work. The present invention has been made to solve the above-mentioned problems, and even when a forklift truck moves in and out of a refrigerator to perform storage and withdrawal work, the display screen of the forklift terminal does not condense. An object of the present invention is to provide a forklift terminal device for a refrigerator, which prevents the display screen from disappearing due to dew condensation.

FIG. 1 is a perspective view of a forklift truck equipped with a refrigerator forklift terminal device. The forklift truck 1 is equipped with a forklift terminal 2 for a wireless LAN system that wirelessly transmits and receives data relating to warehousing to and from a center-side terminal (not shown), and carries out warehousing work according to the received warehousing data. It is something to do. The forklift truck 1 moves in and out of a refrigerator in which luggage is stored for loading and unloading work. Forklift terminal 2
A display 3 for displaying data and a keyboard 4 for inputting data, which are arranged toward the driver's seat, and an antenna 5 for performing wireless communication with the center side terminal are connected to the. A bar code scanner 6 for reading a rack number or the like is arranged in the forklift truck 1 and is connected to the forklift terminal 2 via a code 7.

されている。2 and 3 are diagrams showing a specific configuration of the display 3. A planar transparent heating element, for example, a planar transparent glass 11 containing heat rays, is attached to the display 3 along the LCD 3a which is its display screen. This heat wire is connected to the power source of the forklift truck 1 via the power cord 12 so that the display 3 is kept at a predetermined temperature by being energized. The planar transparent glass 11 has elasticity at its outer peripheral edge and is mounted so as to be fitted to the peripheral edge of the display 3. In the figure, an example is shown in which the seat heater 12 is installed on the back surface of the LCD 3a in the case of the display 3, and the dehumidifying material (silica gel or the like) 13 is stored in the case of the display 3. The energization of the hot wire may be controlled by detecting the ambient temperature of the display 3 or the forklift terminal 2. A communication board 14 and the like are also mounted in the case of the display 3.

る。In the above structure, the display 3 of the forklift terminal 2 is kept at a predetermined temperature by energizing the heat ray of the sheet-shaped transparent glass 11 containing the heat ray. For this reason,
Even when the forklift truck 1 moves in and out of the refrigerator to carry out the warehousing work, the screen formed by the LCD 3a of the display 3 will not be condensed, and the screen will not disappear. Particularly, in the case of the LCD 3a, the liquid crystal cannot be displayed at a low temperature, but this is prevented. Further, as described above, by incorporating the seat heater 12 and the dehumidifying material (silica gel or the like) 13, the heat retaining and dehumidifying effects inside the display 3 are further enhanced. When the dehumidifying material 13 is built-in, it is effective to obtain a dehumidifying action by making the inside of the display 3 airtight.
