Description

Detailed Description of the Invention [Technical Field] The present invention relates to a microfilm image reproducing device that electrically reads an image recorded on a microfilm and prints out the read image information using a laser beam printer or an inkjet printer. Regarding.

[Prior Art] Conventionally, there have been known devices that record large amounts of information such as documents at high density on microfilm, read the recorded images on the microfilm each time as needed, and print them out in a predetermined size. ing.

In particular, as an image reproducing device that is capable of image information processing such as electronic transmission and editing of image information, an image reading device that uses an image sensor to read images recorded on a microfilm, and a microfilm that is read by the image reading device. a display means that optically or electrically displays an image of the display means; an instruction means that refers to the display image of the display means to indicate the reading output range of the display image; 2. Description of the Related Art An apparatus is known that includes an image output means that reads an image using a reading means and converts an image corresponding to the read information onto a recording paper.

FIG. 1 is a schematic configuration diagram of a conventional device of this type, centering on the image reading means.

In this figure, frame 1a of microfilm F
and 1b are emitted from the halogen lamp 2,
It is illuminated by light condensed by a condensing lens 3. Frame 1a of film F proven in this way
and 1b are transmitted through an optical system consisting of an imaging lens 4 and a fixed mirror 5 to a one-dimensional line sensor 6 composed of a CCD (charge coupled device) or the like.
The image is formed on the scanning plane. This one-dimensional line sensor 6 is fixed to a carriage 9 that can freely reciprocate while being guided by a pair of parallel guides 7 and 8. Further, since the carriage 9 is fixed to a wire 10 that makes linear motion by rotation from the motor 11, the one-dimensional line sensor 6 scans and reads image information by driving the motor 11.

A photo interrupter 13 that detects the start of reading scanning is arranged on the main body side of the device, and when a light shielding plate 14 fixed to the carriage 9 blocks the light from the photo interrupter 13 as the carriage 9 moves, the photo interrupter 13 detects the start of reading scanning. Interrupter 13 generates a read scan start timing signal.

On the other hand, a switching mirror 15 is arranged between the imaging lens 4 and the fixed mirror 5, and each image of the frames 1a and 1b of the film F is displayed on a display means via the switching mirror 15, the projection lens 16, etc. An enlarged image is also formed on the screen 17.

On this screen 17, a reading frame for a half-size image and a reading frame for a full-size image are printed, respectively. If the recording paper set in a laser beam printer (not shown) is vertically oriented, the laser beam printer will read the half-size area surrounded by the reading frame and print it out; Ba,
A laser beam printer reads the full size area surrounded by the reading frame and prints it out.

FIG. 2 shows the screen 1 that indicates the reading output range of the image displayed on the screen 17 mentioned above.
7 shows an example of the configuration of the instruction means accompanying 7. here,
Guides 20 and 25 are arranged along the lower end and left end of the screen 17 so as to be perpendicular to each other.

The guide 20 has a screen 17 equipped with a cursor 18 having a substantially rectangular shape and a cursor 19 whose tip is formed at an acute angle to make it easy to indicate, as indicating members for indicating the reading output range in the left-right direction (horizontal direction). It is arranged so that it can slide freely in the left and right direction along the lower side of the. The cursors 18 and 19 are electrically connected to sliding terminals of so-called linear potentiometers 21 and 22 whose resistance values vary linearly. Each of the linear potentiometers 21 and 22 has one end connected to the power supply Vcc, and the other end grounded.

With this configuration, the linear potentiometers 21 and 22 can move the cursors 18 and 1 from the reference position X ₀ on the screen 17, respectively.
Voltages V ₁₈ and V ₁₉ proportional to the distance to 9 are output.

The guidance guide 25 has cursors 23 and 24, each of which has an acute angle tip for easy indication, as indicating members for indicating the reading output range in the vertical direction (vertical direction) along the left side of the screen 17. It is arranged so that it can slide freely in the vertical direction. The cursors 23 and 24 are electrically connected to sliding terminals of linear potentiometers 26 and 27, respectively. The linear potentiometers 26 and 27 both have one end connected to the power supply.
Connect to Vcc and ground the other end.

With this configuration, the linear potentiometers 26 and 27 output voltages V ₂₃ and V ₂₄ that are proportional to the distances from the reference position y ₀ on the screen 17 to the cursors 23 and 24, respectively.

To simplify the explanation, here, the frame corresponds to the paper size A4 in the printer, and the frame corresponds to the A3 paper size.
Assuming that it corresponds to a plate, the image "A" in Figure 2 is as shown in Figures A and B,
They will be printed on A4 and A3 paper respectively. Also, a, b, in Figures 2 and 3,
The length dimensions indicated by c and d are the above-mentioned voltages V ₁₈ ,
It is calculated from V ₁₉ , V ₂₃ , and V ₂₄ .

However, when the image reading range "B" which is larger than the A4 size paper as shown in Fig. 4 is specified by the above-mentioned instruction means and printed on the printer, even if the paper currently prepared in the printer is the A3 size paper. There is no problem if you use A4 size paper, but if A4 size paper is prepared, part of the printed image will be missing as shown in Figure 5. Users of this type of equipment should always check the paper size before operating the equipment.
However, if you think about your daily work,
This type of confirmation is often forgotten, complicated, and bothersome.

[Purpose] Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks and to compare the image reading range specified by the instruction means for specifying the image reading range and the recording paper size to be printed by the printing means. Therefore, it is an object of the present invention to provide a microfilm image reproducing device which generates a warning when the reading range is larger than the paper size.

That is, the present invention provides an image reading means for reading an image recorded on a microfilm, a display means for displaying an image of the microfilm read by the image reading means, and an apparatus for indicating the reading range of the image displayed on the display means. and printing means that reads an image in the range specified by the instruction means with an image reading means and prints it out on recording paper in a predetermined size. The apparatus is characterized by comprising a comparison means for comparing the recording paper size to be printed on the means, and a warning generation means for generating a warning in response to an output of the comparison means indicating that the reading range is larger than the recording paper size. do.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

Note that detailed explanations of components similar to those of the above-mentioned conventional example will be omitted.

First, as shown in Figure 2 above, the reference position
Output voltage V ₁₈ , V 19 , V 23 , V 24 proportional to the distance from x ₀ , y 0 to cursors ₁₈ , ₁₉ , ₂₃ , ₂₄
The values obtained by converting the values to the lengths on the paper surface of the printer (not shown) are respectively l ₁₈ , l ₁₉ , l ₂₃ , and l ₂₄ , and the lengths of the points P and P on the screen 17 on the recording paper surface are respectively Corresponding to the length of A4 and A3 plates, respectively, as shown in Figure 3 A and B, x _p = 210 (mm),
y _p = 297 (mm), x _p = 420 (mm), y _p = 297 (mm)
becomes.

If A4 size paper is currently selected as the recording paper in the printer, cursors 18 and 19
If you specify an area outside the frame indicating the A4 size as the image reading range, as described above, the 5th
This results in the problem of missing images as shown in the figure. Therefore, in the present invention, before printing, it is determined whether the magnitudes of l ₁₈ and l 19 calculated from the voltage values of V ₁₈ and V ₁₉ obtained from the cursors 18 and ₁₉ have become larger than x _p , If it gets too big, some kind of warning, such as an LED (light emitting diode)
The system displays a warning message or sounds a warning buzzer, thereby prompting the operator to take measures such as replacing the paper cassette.

FIG. 6 shows an example of the configuration of the present invention for performing such an operation, where 28 indicates the cursor 18, 1
Output voltages from 9, 23, 24 V ₁₈ , V ₁₉ , V ₂₃ ,
This is an A/D converter that performs A/D (analog-digital) conversion of V ₂₄ , and the signal converted to digital data by this A/D converter 28 is then transmitted to a CPU (central processing unit) 29. . Also, 31
is an external printing means such as a laser beam printer or a copying machine. 30 is an LED that displays a warning in response to an instruction signal from the CPU 29. The paper size signal PS is sent from the external printing means 31 to the CPU 29.
Further, the CPU 29 has an internal memory in which a control procedure according to the present invention as shown in FIG. 7 is stored in advance, and performs control operations in accordance with this control procedure.

Next, according to the flowchart in FIG.
An example of the operation of the device of the present invention shown in the figure will be explained. First, in step S1, the current paper size is checked, and then in step S2, it is determined whether the paper size is A4 or not.
If the judgment is affirmative, the output voltages V ₁₈ and V ₁₉ are converted into lengths l ₁₈ and l ₁₉ in step S3, and in the next step S4, these l ₁₈ and l ₁₉ are converted to 210 (mm) on the A4 size.
(=x _p ), and when it is determined that it is larger, in the next step S5
A warning is generated by lighting up LED 30. Further, when it is determined in step S2 that the paper size is not A4, the process directly proceeds to the next processing routine (not shown) since there is no problem with A3. In this example, the recording paper size is A4.
Although the explanation has been given using the size of the paper and the A3 size as examples, it is needless to say that the size is not limited to these sizes. Further, although an LED display is used as a warning means, a buzzer or the like is also suitable.

Furthermore, although the present embodiment has been described assuming that the operation is performed under a constant magnification, the present invention can also be applied to a case where the magnification changing operation is performed by a separate magnification changing means. In addition, the image reading means is not limited to a one-dimensional line sensor, but a two-dimensional image sensor may be used to perform the same warning operation as described above by associating addresses on the screen with each element array of the image sensor. It is possible.

[Effect] As explained above, according to the present invention, by comparing the paper size prepared in the printing means with the image reading range, a warning is generated when it is determined that the reading range is larger. As a result, it is possible to reliably prevent image chipping during printing.
