Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an enlarged doorscope image display unit that enlarges and displays a visible image of a doorscope for confirming a visitor before opening a door.
[0002]
[Prior art]
Conventionally, especially when looking at a door scope attached to an entrance door, it was not possible to identify a visitor unless the eyes were close enough to touch the door surface.
[0003]
[Problems to be solved by the invention]
For this reason, the guilt and posture of the peeping posture may be overwhelmed, and the door may be opened without confirming the visitor, or the door scope may be momentarily darkened so that the eyes can be approached. You may find that you are looking into the.
The present invention provides that it is not necessary to take an unreasonable posture by magnifying and viewing, and by mounting the doorscope image enlarged display unit inside the doorscope room, it is possible to obscure that there is a person inside. [0004]
[Means for Solving the Problems]
A door scope image enlarged display unit according to the present invention that achieves the above object,
It has a dual image control circuit for resolving the visible image of the door scope and converting the image into an electronic image, a monitor liquid crystal screen for displaying the image, a display unit consisting of a power supply unit and a switch unit, a magnet The display unit containing the magnet is mounted on the indoor side of the door scope so that the visible image of the door scope can be enlarged and viewed.

DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described with reference to the drawings.
1 is a plan view of a cross section 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. FIG. 5 is a plan view, and FIG.
[0006]
As shown in FIGS. 1 and 2, a magnet 7 is fixed to the back 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 a hole 11 is drilled at the position where it is aligned.
To use the display unit 10 for a conventional iron door 1 with a door scope, the holes 11 of the display unit 10 are aligned with the flanges of the door scope 2 and mounted. Since the magnet 7 is fixed to the display unit 10, the magnetic force causes the iron door 1 and the display unit 10 to be immobile.
In the case of a wooden or aluminum door, as shown in FIGS. 4 and 5, the burring hole 13 of the iron plate 8 is aligned with the flange of the door scope 2, and is fixed to the wooden or aluminum door 12 with the screw 9. It can be used similarly to the iron door 1 shown above. The magnetic force should be strong enough to open and close doors and withstand vibrations such as earthquakes. The door scope may be an existing fish-eye lens type, or may be replaced with a wide-angle lens or a new one.
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 liquid crystal screen. The switch 5 may be turned on only while the switch 5 is being pressed, or may be provided with a timer function so that the power is turned on only within a set time by a single push.

【The invention's effect】
As described above, according to the door scope image enlarged display unit according to the present invention, there is no guilt of an attitude of peeping from the act of looking at the screen, and the visitor does not take an unreasonable posture of approaching the door. Can be confirmed. Also, by mounting the display unit inside the door scope room, the light in the room is blocked, and there is an effect that a person in the room cannot recognize that it has approached the door, which is effective for crime prevention.
Known security cameras, intercoms with televisions, and the like are very expensive because they have various functions such as a camera, a video, a video playback function, and a 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 further increases the cost. ADVANTAGE OF THE INVENTION According to the doorscope image enlarged display unit of this invention, it can provide cheaply only by the function which makes it easy to see safely, reliably, and simply.
