Abstract

PURPOSE:To easily specify an area without reference to its shape by judging the specified area from optional drawing information drawn on a transparent member. CONSTITUTION:A transparent sheet 9 as a transparent member is arranged on the front surface of a screen 4 and taken up above and below the screen 4. An operator specifies a desired area on the transparent sheet 9 with a specific pen by using drawing information on a hook frame, a circle, etc., which are plotted optionally. Then a linear sensor 8 moves linearly at equal speed as shown by an arrow M parallel to the screen surface to make a prescan for reading the plotting information on the transparent sheet 9 across the screen as area specification information. Thus, the specified area is judged from the optional plotting information plotted on the transparent member, so the area can easily be specified without reference to its shape.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a reader printer that optically enlarges and projects an image on a microfilm or the like and reads image information by scanning the projected light.

(Prior Art) Conventionally, as this type of reader printer, there is a microfilm reader printer as shown in FIG. 7, for example.

In the reader printer, a reduced image on a roll-shaped microfilm 102 illuminated by an illumination lamp 101 is enlarged by an imaging lens 103 and then reflected by a first reflecting mirror 104.
．． The image is focused on a screen 106 via a second reflecting mirror 105. When printing out the formed image, first move the linear light receiving sensor 107 along the arrow A.
The screen is scanned by performing uniform linear movement parallel to the screen surface, and the projected image incident from the second reflection mirror 105 is read. The image read in this way is sent to a printer, typically an electrophotographic printer, to obtain an enlarged and reproduced image.

If you want to specify a specific area of the image and, for example, reproduce a partial image of the image (trimming), there are methods for specifying that area, inputting coordinates into the device from a digitizer or keyboard, and methods provided on the screen frame. such as those that detect a specified area from the resistance voltage of a position sensor.
Many things were proposed.

(Problem to be Solved by the Invention) However, as a means of specifying an arbitrary area on a display image, inputting coordinates from a keyboard is inexpensive, but it is difficult to input coordinates by typing the coordinates while measuring the display image on the screen 106 with a scale. Since it required manual labor, its operability was significantly inferior.

In addition, the screen touch type using a digitizer is
The digitizer itself is expensive, and the cost of increasing the resolution of area designation increases exponentially. Furthermore, a digitizer that can give instructions while viewing the image on the screen 106 naturally has to be placed in front of the screen, which reduces the visibility of the screen 106 and significantly sacrifices the league function as a reader printer. there were.

In devices that detect a specified position from the resistance voltage of a positive sensor installed in the screen frame, increasing the resolution of area specification requires wider wires for the position sensor, which may require a larger screen frame or position detection. Since the linearity decreases, a problem arises in that the position sensor must be divided into several parts.

The present invention has been made to solve the problems of the prior art described above, and its purpose is to provide a reader that can specify areas of a display image with high precision, at low cost, and easily. The purpose is to provide printers.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a screen that serves as a display screen for images projected by the projection optical system, and a screen that is located between the projection optical system and the screen and that is connected to the projection optical system. In a reader printer equipped with a reading means for reading and scanning a projected image, a transparent member facing the reading means is disposed between the screen, and any drawing information drawn on the transparent member by inverting the reading means. It is characterized by reading.

Furthermore, it is effective to provide an imaging lens that is located between the reading means and the screen and forms an appropriate image of the drawing information on the transparent member on the reading means.

It is desirable that the transparent member be detachably attached to the reading means.

(Function) In the present invention having the above configuration, the specified area is determined based on arbitrary drawing information drawn on the transparent member, so it is possible to easily specify an area regardless of shape.

Further, by providing an imaging lens that is located between the reading means and the screen and properly forms an image of the drawing information of the transparent member on the reading means, the drawing information can be read accurately.

By disposing the transparent member detachably with respect to the reading means, it can be removed from the front of the screen when not in use, and the visibility of the image on the screen can be ensured.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. FIG. 1 is a configuration diagram showing a microfilm reader printer according to the present invention.

In the figure, a reduced image of a roll-shaped microfilm 2 illuminated by an illumination lamp 1 is enlarged by an imaging lens 3 and focused on a screen 4. The first reflecting mirror 5 and the second reflecting mirror 6 are for bending the enlarged optical path to make the apparatus compact.

The light-receiving elements 7 are arranged on the linear light-receiving sensor 8 in a direction perpendicular to the scanning direction indicated by an arrow M, and each element forms a pixel of a digital image.

A transparent sheet 9 as a transparent member is disposed on the front surface (operator side) of the screen 4, and can be rolled up between the top and bottom of the screen 4. Note that various winding methods may be employed, such as manual winding, electric winding, electric winding of a certain amount, and the like. The operator specifies a desired area on the transparent sheet 9 using drawing information such as a hook frame or a circle arbitrarily drawn using a predetermined marker. Thereafter, the linear sensor 8 is activated by a signal from an operation switch (not shown).
It moves linearly at a constant speed in the direction of arrow M parallel to the screen surface, and performs pre-scanning to read the drawing information on the transparent sheet 9 through the screen as area designation information. At this time, the light receiving element 7
faces the screen 4 side, and the drawing information on the transparent sheet 9 can be read by blocking the projected light with the linear light receiving sensor 8 itself. After completing the pre-scan to read the drawing information on the transparent sheet 9, the linear light-receiving sensor 8 reverses to the direction shown by the dotted line 8a and immediately starts the main scan in the direction of the arrow Ma, reading the area designation information read and stored in the previous scan. Sends a signal to the digital printer according to the following. FIG. 2 shows an external view of a reader printer using the present invention. As is clear from FIGS. 1 and 2, since there is no external special scanning optical system for reading designated areas, it is possible to achieve a compact appearance comparable to that of a normal glue stick.

Further, in the above embodiment, the transparent sheet 9 was wound into a roll and configured to be movable up and down, but for example, as shown in FIG.
It may be configured to be removable by being pulled down like a curtain, and to be removed from the front surface of the screen 4 when not in use.

Next, referring to FIG. 4, a specific area specifying operation of the present invention will be explained. For example, if you want to extract only the graph from the image projected on the screen 4 and print it out, insert the Ben 11 on the transparent sheet 9 in front of the screen 4.
Add a mark (drawing information) that becomes area specification information. ben 1
The mark drawn with the ink No. 1 has a contrast of brightness and darkness due to external light, and can be sufficiently read by the linear light-receiving sensor 8 even through the screen 4 having a diffusion surface. The reader printer body is equipped with a memory that records the data obtained from pre-scanning.
It is used to determine which area in the read image in the main scan corresponds to the area indicated by the data.

In advance, the operator performs trimming to extract partial images,
It is assumed that a switch (not shown) for selecting masking for erasing a partial image is being operated, and a trimming key is being operated here. Then, as shown in the figure, only the graph within the rectangular frame is printed onto the transfer material 12 and output from the printer 13. In the above embodiment, the printout area was specified using a square frame, but according to the present invention, the area can be specified using not only a circular or triangular frame but also an irregularly shaped frame. Moreover, the transparent sheet 9 is
When rewriting, an unused portion wound into a roll may be sent out, or writing may be performed using an erasable ink (for example, water-based ink). Note that an eraser for erasing ink on the sheet may be provided in the winding section so that ink is automatically erased when the sheet is wound.

FIG. 5 is a configuration diagram showing a reader printer according to another embodiment of the present invention. In this embodiment, an imaging lens 21 having a focal length that allows the information on the transparent sheet 9 to be properly focused on the light receiving surface of the light receiving element 7 is provided. In the above embodiment, the linear light receiving sensor 8 is connected to the screen surface or the transparent sheet 9.
was unable to sense detailed images and was only able to recognize simple patterns such as frameworks. However, in this embodiment, by providing an imaging lens 21 that focuses on the transparent sheet when the linear light receiving sensor 8 faces the screen 4 side, clear image recognition is possible and more accurate area specification is possible. be able to. Furthermore, with such highly accurate image recognition, it is possible to sense, for example, pictographs, messages, etc. written on the transparent sheet 9, and these can also be superimposed on images and printed out. Figure 6 shows the situation. That is, the operator previously turns on a switch (not shown) for the Saiichi Valley that instructs overlapping. Then, place rA (lambda)j at an arbitrary position on the transparent sheet 9, for example, between the upper right
When writing is performed and a printout key (not shown) is operated, the linear light receiving sensor 8 turns to face the screen 4 and starts forward operation. The linear light receiving sensor 8 recognizes the character rAJ written on the transparent sheet 9 together with its area, and records this data in the memory. Then, when printing out the projection image read by the main scan, the data "c" in the memory is overlaid on the print image.

In the above embodiment, a transparent sheet material is used as the transparent member, but other materials such as glass or plastic may also be attached to fit the screen frame.

(Effects of the Invention) The present invention has the above-described configuration and operation, and since the specified area is determined based on arbitrary drawing information drawn on the transparent member, it is possible to easily specify an area regardless of the shape. You can do it. Also, there is no need for a digitizer or keyboard, etc.
Reliable area specification can be performed with an inexpensive configuration.

Further, by providing an imaging lens that is located between the reading means and the screen and properly forms an image of the drawing information of the transparent member on the reading means, the drawing information can be read accurately. Therefore, it becomes possible to read not only the exact position of the specified area but also arbitrary pictograms.

By disposing the transparent member detachably with respect to the reading means, it can be removed from the front of the screen when not in use, thereby ensuring the visibility of the image on the screen.
