Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cabinet device used in video equipment and the like.

Conventional technology In recent years, optical sensors have been widely used in video equipment, etc.
Furthermore, the cabinet is equipped with a window so that you can see the status of the machines inside.

A conventional cabinet device will be explained below.

FIG. 2 shows a conventional cabinet device. In Figure 2, 1 is a cabinet that does not transmit light;
is a window that allows you to see what's inside. 3 is a light sensor.

Problems to be Solved by the Invention However, with the above conventional configuration, the light sensor may malfunction due to strong external light such as sunlight entering through the window. However, according to this, the interior was in poor condition and had the disadvantage that it did not function as a window.

The present invention solves the above-mentioned conventional problems, and aims to provide a cabinet device that does not malfunction and allows the interior to be seen clearly.

Means for Solving the Problems To achieve this object, the present invention provides an optical sensor, a Hough mirror provided in the window of a cabinet surrounding the optical sensor, and limiting transmitted light to less than 20%, and a Huff mirror for illuminating the interior. It has a configuration equipped with a light source.

Function: With this configuration, light from the outside is restricted to the half mirror, which eliminates malfunction of the optical sensor.Therefore, the window can be made wide, and the interior conditions can be clearly seen using the interior lighting.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

In Fig. 1, 4 is a cabinet that does not allow light to pass through, 5 is a half mirror installed in the window that limits the light transmittance to less than 20 inches, and 16 is a light sensor that detects the condition of a tape (not shown), etc. It is.

Reference numeral 7 denotes an internal illumination lamp, which is designed so as not to affect the optical sensor 6.

As described above, according to this embodiment, on the cabinet window,
By installing a half mirror that limits transmitted light to less than 20%, even if there is strong light outside, the light sensor will not malfunction due to the external light, and on the other hand, it will not affect the light sensor. Lamps are installed to illuminate the interior, allowing a clear view of the interior through the wide windows.

Effects of the Invention As described above, the present invention provides a light sensor using external light by providing a half mirror that limits transmitted light to less than 2% and a light source for illuminating the interior of the cabinet window. This makes it possible to realize an excellent cabinet device that can prevent malfunctions of the cabinet and allow a clear view of the inside.
