[Problems to be Solved by the Invention]

For this reason, the guilty feeling of peeping and the posture are overwhelmed, and the door scope is momentarily darkened to open the door without confirming the visitor, or to bring the eyes closer, and there is a person inside and outside. You may find that you are looking into. The present invention provides that it is not necessary to take an unreasonable posture by magnifying the view, and by mounting the door scope image magnifying display unit on the indoor side of the door scope, it is not possible to know that there is a person inside. [0004]

[Means for solving problems]

The door scope image magnifying display unit according to the present invention that achieves the above object has a dual image control circuit for resolving a visible image of the door scope and converting the image into an electronic image, and displays the image. A magnet is fixed to the display unit consisting of the monitor LCD screen, power supply unit, and switch unit. By mounting the display unit with this magnet inside the door scope, the visible image of the door scope can be enlarged. It is made to be able to be seen.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, the present invention will be described with reference to the drawings. FIG. 1 is a sectional plan view of a main part according to the present invention, FIG. 2 is a front view of FIG. 1, FIG. 3 is a block diagram of the present invention, and FIG. The plan view and FIG. 5 are cross-sectional side views of the main parts of FIG.

As shown in FIGS. 1 and 2, a magnet 7 is fixed to the back surface of a display unit 10 including an image control circuit 3, a monitor liquid crystal screen 4, a power supply unit 6, and a switch unit 5, and the door scope 2 of the display unit 10 is formed. A hole 11 is made at the alignment position with. To use this display unit 10 for a conventional iron door 1 with a door scope, align the hole 11 of the display unit 10 with the flange of the door scope 2 and mount it. Since the magnet 7 is fixed to the display unit 10, the iron door 1 and the display unit 10 are immobile due to the magnetic force. In the case of wooden or aluminum doors, as shown in FIGS. 4 and 5, align the burring hole 13 of the iron plate 8 with the flange of the door scope 2 and fix it to the wooden or aluminum door 12 with screws 9. It can be used in the same way as the iron door 1 shown above. The magnetic force shall be strong enough to withstand the opening and closing of doors and vibrations such as earthquakes. Further, the door scope may be an existing fisheye lens type, and may be replaced with a wide-angle lens or the like or newly installed [0007].

When confirming the visitor, the power is turned on by pressing the switch 5, and the image of the door scope is enlarged and displayed on the monitor LCD screen. The power of the switch 5 may be turned on only while it is pressed, or it may be turned on only within the set time by having a timer function and pressing it once.

[Effect of the invention]

As described above, according to the door scope image magnifying display unit according to the present invention, there is no guilty feeling of peeping from the act of looking at the screen, and the visitor does not take an unreasonable posture of bringing his eyes close to the door. Can be confirmed. Further, by installing the display unit on the indoor side of the door scope, the light in the room is blocked, and there is an effect that it is difficult for a person inside to know that the person is approaching the door, which is effective for crime prevention. Further, well-known security cameras, intercoms with TVs, etc. are very expensive because they are equipped with multiple functions such as a camera, video, video playback function, and proximity sensor in addition to audio and video functions. When these are newly installed in an existing house, wiring and installation work are required, which makes them even more expensive. According to the door scope image magnifying display unit of the present invention, it can be provided at low cost by providing only a function that makes it safe, reliable, and easy to see.
