Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for selectively observing a monitor image and other information.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, when operating a personal computer, word processor, etc. or observing a monitor image, place a material or keyboard near the monitor screen and operate the keyboard while observing the monitor image or material. ing. In this case, the observer observes the monitor screen and sometimes shifts his or her line of sight to the material so that they can observe each other alternately. At the same time, the keyboard is operated to reproduce, write, and correct the monitor image as necessary.However, if the keyboard operator is a beginner or is unfamiliar with the operation, the keyboard It was difficult to operate the keys without looking at the code. Therefore, in such a case, it was necessary to observe, read, and operate while alternately observing the monitor screen, the material, and the keyboard, and the neck and the line of sight were often moved, and it was easy for fatigue. Further, such work is extremely complicated.

In view of such problems, an object of the present invention is to provide an apparatus capable of observing a monitor image and other information without moving the line of sight.

[0004]

[Means for Solving the Problems]

 The monitor according to the present invention and the device for observing other information are arranged such that the monitor screen and at least one information are arranged facing each other with respect to the dichroic mirrors diagonally positioned with respect to each other. The light flux of the image is configured to overlap the optical path of the monitor image by passing through the dichroic mirror so that at least one of the two images can be observed selectively or by superimposing the two images.

[0005]

[Action]

 When observing an image on the monitor screen, the observer can superimpose one image of information on the same optical path through the dichroic mirror, or select one of two or more images for observation. Moreover, since the image of the information is superimposed on the same optical path as the optical path of the monitor image, it can be observed without moving the line of sight.

【Example】

 A first embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a block diagram of an apparatus according to this embodiment. For example, in front of the monitor screen 1a of the monitor 1 for a personal computer, a dichroic mirror 2 is arranged so as to be inclined with respect to the optical path of the monitor image. It has become. A half mirror 4 for placing the material 3 is located on one surface outside the optical path of the monitor image, and a light source 5 for transmitting and irradiating the material 3 is provided behind it. Further, the dichroic mirror 2 is also obliquely positioned with respect to the half mirror 4, and the light flux of the image of the material 3 transmitted from the light source 5 through the material 3 and the half mirror 4 is reflected by the dichroic mirror 2 as shown by the broken line. As a result, it overlaps the optical path of the monitor image. A keyboard 6 is placed outside the optical path of the monitor image at a position substantially facing the half mirror 4, and the light flux of the image of the keyboard 6 is reflected by the half mirror 4 as shown by the solid line and then reflected by the dichroic mirror 2. It is reflected and overlaps the optical path of the monitor image.

Further, when the observer P sits at a predetermined position facing the monitor screen 1a for monitor observation or the like, the observer (the eye) is positioned on the optical path of the monitor image.

Since the present embodiment is configured as described above, when the observer P is sitting at a predetermined position and observing the monitor screen 1a, the light flux of the monitor image indicated by the alternate long and short dash line is the dichroic mirror 2 Will be transmitted and will enter into the eyes of the observer P. Next, when trying to observe the material 3, if the light source 5 is turned on, the light flux passes through the material 3 and the half mirror 4, is reflected by the dichroic mirror 2, and overlaps the optical path of the monitor image. In this case, if the light intensity of the light source 5 is made larger than the light intensity of the monitor screen 1a by a predetermined amount, the image of the document 3 can be seen more clearly when the image of the document 3 and the monitor image are superimposed, and the monitor image Does not look so good. Therefore, it is not necessary to turn off the power of the monitor 1 when observing the document 3. The light intensity of the light source 5 and the light intensity of the monitor screen 1a may be adjusted by adjusting the light amount of the monitor screen.

Next, when it is desired to superimpose the image of the keyboard 6 on the monitor image, the light source 5 is turned off, and the light flux of the image of the keyboard 6 due to the room light or the like is reflected by the half mirror 4 to be dichroic mirror. 2 goes up, is reflected here, and will be superposed on the optical path of the monitor image. At this time, if the light amount of the monitor screen 1a is adjusted to be small, only the image of the keyboard 2 can be clearly observed without turning off the power of the monitor. Since the monitor screen 1a becomes black when the input signal to the monitor 1 is instantaneously cut, the image of the document 3 or the image of the keyboard 2 may be observed in this state. When observing any of the images alone, the light source 5 may be turned off in order to observe the monitor screen 1a, and the power of the monitor may be turned off in order to observe the document 3. To observe, the light source 5 and the monitor 1 may be turned off. When the keyboard 6 is not projected and observed, a transmissive glass may be arranged in place of the half mirror 4.

As described above, in this embodiment, the observer P can selectively observe the monitor image, the material 3, and the keyboard 6 without moving the line of sight, and the work such as observation and operation is easy. Moreover, there is a practical advantage that the fatigue of the observer can be reduced.

Next, a second embodiment of the present invention will be described with reference to FIG. 2. The same parts or members as those in the first embodiment described above will be designated by the same reference numerals and the description thereof will be omitted. FIG. 2 shows a schematic configuration diagram of the second embodiment. In this embodiment, the monitor screen 1a of the monitor 1 and the keyboard 6 are arranged at positions facing each other with the dichroic mirror 2 positioned obliquely therebetween. The light flux of the monitor image is reflected by the dichroic mirror 2 and reaches the observer P at a predetermined position. The material 3 is at a position facing the observer P, the material 3 is placed on an opaque material table 8, and no light source for illuminating the material 3 is provided. Due to room light or the like, the light flux of the image of the material 3 passes through the dichroic mirror 2 and is superimposed on the light flux of the monitor image, and is incident on the observer P's eye. The observation target is selected by turning on / off the monitor 1, adjusting the light amount, cutting the monitor signal, or the like. Further, the keyboard 6 is designed so that the observer P can directly observe the light through the dichroic mirror 2. In this case, the line of sight of the observer is slightly different in direction from the case of observing the monitor image and the image of the document 3, but the difference in observation angle is small.

Regarding the second embodiment, a light source for illuminating the material 3 may be provided, and in this case, the light source illuminates the material 3 through transmission or reflection so that the light flux of the image of the material 3 is dice. It will pass through the croic mirror 2. Then, the material 3 and the monitor image can be selectively observed by switching ON / OFF the light source and processing the monitor signal (such as instantaneous cut).

In addition, in each of the above-described embodiments, it is possible to invert and observe each image by adding one reflection mirror.
