  Each electronic device arranged on the control panel as described above is adapted to the work while pressing the button part of the operation area part while the operator looks at the setting value displayed on the display area part in the factory etc. By setting the controlled state, operation control of equipment such as a factory is performed.

  And such an electronic device is not always used in a state where the illuminance in the factory is always appropriate, and may be used in a state where the illuminance is very low such as at night. In addition to using an LCD or the like for the area part and a backlight device for illuminating the button part of the operation area part in the electronic device casing, even if the illumination in the factory is low, the operation is performed by the backlight apparatus. The button part of the area part is illuminated so that the button part can be easily seen and operated.

  However, as a result of using the backlight device in this way, the power consumption of the electronic device is increased correspondingly, and this is not necessarily preferable in the present age when ecology technology is required.

  In addition, since this type of electronic device is often used in, for example, food factories, it must always be sterilized in order to maintain the hygienic state of the living environment, but is always preferable. Maintaining hygienic conditions is cumbersome and may lead to the generation, growth, and proliferation of microorganisms.

  SUMMARY OF THE INVENTION Accordingly, it is a first object of the present invention to provide an electronic device such as a temperature controller that can be easily operated even in a factory with low illuminance such as nighttime while achieving ecological technology. The second object is to provide an electronic device such as a temperature controller configured to always ensure an antibacterial state in order to maintain the sanitary state of the living environment.

  In order to achieve the first object, an electronic device such as a temperature controller according to the present invention includes a temperature controller configured by attaching a display plate to a front surface portion of an electronic device housing that houses a control unit. An electronic device, wherein the display board includes a display area section for displaying a set value and the like, and an operation area section for operating the control unit, and controls the control unit to the operation area section. A button portion for forming a phosphorescent agent coating portion made of a phosphorescent pigment on the back surface side of the display plate facing the button portion, and the phosphorescent agent coating portion on the display plate It is characterized by being transparently displayed on the front side of the button part.

  By having such a configuration, the phosphorescent material application part is formed on the back surface facing the button part in the operation area part of the display board, so that the phosphorescent material application is performed in a time zone where the illuminance in the factory is relatively high, such as daytime, for example. Light will be accumulated in the unit, and if the accumulated light becomes dark in the factory such as at night, the button unit can be illuminated without using a backlight device etc. It is easy for the user to operate the buttons so that there are no errors, and it is suitable as an ecological technology.

  Furthermore, since the phosphorescent material application part is formed on the back side of the surface plate, even if the display plate is repeatedly touched by the operator's hand for the operation of the button part, it does not peel off from the display plate. .

  Moreover, in order to achieve the second object, an electronic device such as a temperature controller according to the present invention is characterized in that an antibacterial agent coating layer portion made of a transparent body is formed on the front surface of the display board. .

  Therefore, the display board can suppress the generation / growth / growth of microorganisms by the antibacterial agent coating layer, and can always maintain the hygienic state of the living environment.

  According to the present invention configured as described above, by forming the phosphorescent material application part on the back surface facing the button part in the operation area part of the display board, for example, a time zone in which the illuminance in the factory such as daytime is relatively high In addition, light is accumulated in the phosphorescent material application part, and the accumulated light illuminates the button part without using a backlight device or the like when the factory becomes dark, such as at night. It is possible to perform button operation by an operator easily and without error, and it is preferable as an ecology technique.

FIG. 4 is an enlarged cross-sectional view of a main part in FIG. 3, and FIG. 5 is a perspective view depicting a use state of the embodiment shown in FIG.

  In FIG. 1, a temperature controller 1 as an electronic device includes an electronic device housing 2. The electronic device casing 2 includes a rear case 3 that houses a sub-board (not shown) constituting the control unit, a terminal 2 connected to an external device, and the like, and a display unit that is disposed on the surface portion side of the rear case 3. It is comprised with the front case 4 which accommodates the main board | substrate 5 to comprise.

  A thin display board 6 is affixed to the front surface portion 4 a of the front case 4.

  As shown in FIG. 2, the display board 6 includes a display area 6a for displaying setting values output from the display unit and an operation area 6b for operating the control unit. is doing.

  The display area 6a is configured to be transparent so that control values and the like output from the main board 5 are transmitted through a display device (not shown) such as an LCD.

  The operation area portion 6b is formed with a plurality of button portions 6b-1 for controlling the control unit.

  The button portion 6b-1 is configured to be able to operate the switch portion 5a provided on the main substrate 5 side by pushing the plunger 6b arranged opposite to the display plate 6 in a state where the display plate 6 is slightly bulged. .

  And the display board 6 is the base material 7 which consists of resin materials, such as PET, the antibacterial agent coating layer part 8 formed in the front surface of the surface part side of the base material 7, and the black printed on the back surface side of the base material 7 On the coating portion 9, the phosphorescent agent application portion 10 formed so as to form the outer peripheral portion of the button portion 6 b-1 on the back surface side of the base material 7, and the front surface portion 4 a of the front case 4 in the black coating portion 9. The adhesive layer portion 11 is attached to the opposite surface, and the adhesive layer portion 11 is used to be attached to the front surface portion 4a of the front case 4 via the sealing material 11a. ing.

  The base material 7 is black through the black coating portion 9 except for the button portion 6b-1 in the display region portion 6a and the operation region portion 6b, and the portion of the button portion 6b-1 is thin, for example. It is gray to clarify the area.

  The antibacterial agent coating layer portion 8 is configured by printing an ink containing an antibacterial agent on the entire front surface portion of the base material 7, and is transparent so that the display region portion 6b and the operation region portion 6b are transparently exposed. It has become.
