Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a reader printer for enlarging and projecting and copying microfilm as an information recording medium.

(Prior Art) Conventionally, for example, in a microfilm reader printer equipped with an automatic search device, when searching for a predetermined image frame on a film, the predetermined frame on the film often deviates from a predetermined position. In this case, if the transfer is continued as is, the transferred image will shift from a predetermined position on the transfer material, and sometimes a portion of the image may be missing.

(Problem to be Solved by the Invention) For this reason, in conventional reader printers, if a desired frame is off the predetermined position on the screen, the operator moves the film little by little while observing the screen. There was a problem in that the desired image had to be aligned to a predetermined position on the top, making the task cumbersome.

Therefore, the present invention has been made in order to solve the problems listed in L of the conventional example, and its purpose is to prevent the image from being disposed on the screen even if the image position of the information recording medium deviates from the predetermined position. An object of the present invention is to provide a reader printer capable of easily and accurately correcting positional deviation by inputting a predetermined position into an input panel.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a means for projecting an information recording medium onto a screen, a means for transporting the information recording medium, and a means for projecting the information recording medium onto the screen. an input panel disposed above and capable of inputting coordinates on the screen; means for recognizing coordinate data input to the input panel; and an input panel for specifying coordinates of a stop position of an image projected on the screen. and a control means for controlling the position of the information recording medium by calculating the amount of coordinate movement between the first input mode and the second input mode for specifying the coordinates of a predetermined position to be moved. ing.

(Example) The present invention will be explained below based on the illustrated example. 1st
The figure is a perspective view showing the entire microfilm reader printer with a search device to which the present invention is applied, and in the same figure,
The entire apparatus is roughly composed of a copy making section 1, an image observation section 2 provided above the copy making section 1, and a copy control section 3. A cassette 5 for storing a large number of sheets of transfer paper and a discharge tray 6 are arranged at the left end of the machine box 4 of the copy making section l. The cassette 5 is removably attached to the machine box 4, and one of the plurality of cassettes containing transfer paper of various sizes can be selectively attached to the copy making section 1.

On the other hand, the copy making section l has a known image forming means, and copies the image of the microfilm as an information recording medium onto the transfer paper fed from the cassette 5, and converts the transfer paper on which the transfer image is formed into an image. The sheets are discharged onto the discharge tray 6 with the formed side facing upward, and stacked on top in the order in which they were discharged. Machine box 7 of image observation section 2
A transmission type screen 8 for observing the image of the microfilm and an optical system for projecting the image onto the screen 8 are disposed, and an enlarged image of the microfilm can be observed on the screen 8.

The copy control unit 3 includes a power switch 10 that supplies power to the entire apparatus. A copy command switch 11 for instructing the start of copying, and a key manual section 12 provided with a search item entry capo for inputting a search item 1 of desired group information to be searched, such as a case number or a frame number, are provided. There is.

The copy making section l has a photosensitive drum 15 on which a transparent insulating layer is formed on a photoconductive layer, as shown in FIG.
The photosensitive drum 15 rotates at a constant speed in the direction of the arrow and is positively charged by a positive charger 16, and then when it reaches the exposure section 17 on which the microfilm image is projected, the image is exposed to slits and at the same time AC charged. The AC band's standard is received by the device 18. First, the entire surface is exposed by an exposure lamp 19 to form an electrostatic latent image on the surface of the photosensitive drum 15, and the latent image is visualized by a developing device 20. Excess developer on the drum 15 is squeezed out without disturbing the image.

Then, a sheet of transfer paper S fed from the cassette 5 by the paper feed rollers 22, 23, 24 comes into close contact with the photosensitive drum 15, and the images of the photosensitive drums L and 15F are placed on the transfer paper S by the transfer charger 25. transcribed into. At this point, the transfer paper S that has completed the transfer is separated from the photosensitive drum 15 by the separation belt 26 and guided to the drying and fixing section 27 . On the other hand, the remaining toner and developer are wiped off by the blade 28 pressed against the surface of the photosensitive drum 15, and the next copying cycle is repeated again.

The paper feed roller 22 rotates at the start of copying, descends at a set timing, contacts the topmost transfer paper S in the cassette 5, sends out one sheet of transfer paper from the cassette 5, and then rises again. The paper is then fed by the timing roller 23.
．． It is carried out by 24. In the dry fixing section 27,
The transfer paper S is fed while its back side is in close contact with a heated hot plate 29, and is dried and fixed. The dry and fixed transfer paper S is discharged to the discharge tray 6 via discharge rollers 30 and 31.

The gjm detector 2 includes a projection lens 34, as shown in FIG.
Mirror 35.36.37. The copy making section 1 has a half mirror 38 and a microfilm M serving as an information recording medium.
The microfilm M is projected by an illumination lamp 39 disposed in the machine box 4 through a condenser lens 40, and the projected image of the microfilm M is projected along the optical path a or (and) the optical path. When observing one image here, the image on the microfilm M is enlarged and projected onto the screen 8 via the projection lens 34, mirrors 35, 36, and 37 as shown by the optical path a. On the other hand, when copying an image, the image passes through the projection lens 34 as shown in the optical path and mirror 3.
5. The image is enlarged and projected onto the photosensitive drum 15 in the form of a slit through a half mirror 38, a narrow mirror 41, and a shutter (not shown). Incidentally, instead of the half mirror 38, a known total reflection mirror may be moved in and out of the optical path to switch between the observation state and the copying state.

Next, a touch panel 80 is arranged outside the screen 8, and this touch panel 80 is shown in FIG. 4(A).
, As shown in (B), two transparent panels 85 on which strip-shaped conductive members 83 are vapor-deposited in parallel at equal intervals are formed so that the conductive members 83 face each other on the inside and in a lattice shape. That's how it is.

A spacer 84 is arranged between the two transparent panels 85 at the center of a square partitioned by a conductive member 83.
The structure is such that the conductive members 83 deposited on opposing boards do not come into contact with each other.

In the above configuration, when a certain point on the touch panel 80 is pressed with a pen or the like, one transparent panel 85 deforms and contacts the other transparent panel 85, thereby extending in the X direction closest to the point pressed with the pen or the like. When the conductive member 83 and the conductive member 83 extending in the X direction come into contact and a current flows, it is possible to detect the distance in the X and Y directions from a certain reference point at a point pressed with a pen or the like. Note that the details of the mechanism of the touch panel 80 are well known and will therefore be omitted. Furthermore, even if the touch panel has a structure other than the touch panel 80 described above, by inputting a point, the X from the reference point of that point can be calculated.

Any device that can detect the distance in the Y direction may be used.

In addition, FIG. 5 shows Yayaria 9 shown in FIG. 1 as an X.

This figure shows a device for two-dimensional movement in the Y direction. In the figure, 50 is a substrate, and the substrate 50 has left and right side walls 50a, 5.
0b, and a threaded rod 51 is horizontally suspended between the rear end portions of the left and right side walls 50a, 50b.
A guide rail 52 is horizontally suspended parallel to the screw rod 51 between the front end portions of the screw rod 51 . 3 has a rectangular first shape, one end of which is screwed into the screw rod 51 and the other end of which is slidably supported by the guide rail 52.
The frame M-X is an X-direction drive motor such as a pulse motor that drives the screw rod 51 in forward and reverse directions.

Reference numeral 54 denotes a screw rod for the front-rear direction (Y direction) that is rotatably hung horizontally toward the left frame side between the back horizontal frame side 53a and the front side horizontal frame side 53b of the first frame body 53, and 55 similarly A guide rail 5 installed near the right side of the rod and suspended horizontally in parallel with the threaded rod 54.
6 is a second frame whose left side is screwed and supported by the screw rod 54, and whose right side is slidably supported by the guide rail 55; M-Y is Y such as a pulse motor that drives the screw rod 54 in forward and reverse directions; It is a directional drive motor and is attached to the rear horizontal frame side 53a of the first frame 53. F is a microfiche, and this microfiche F is held between a lower transparent plate G2 fixed to a rectangular second frame 56 and an upper transparent plate Gl that can be opened and closed with respect to this lower transparent plate G2. ing.

Furthermore, FIG. 6 is a block diagram of an electric circuit that controls a device that moves two-dimensionally in the x and y directions. Touch panel input section 63, CPU 61, motor drive circuit 6
2. It consists of a motor M-X and a motor M-Y, and all the many key signals of the key human power section 12 are inputted to the CPU 61 in a matrix. In this configuration, when a frame image position is designated using the frame image designation key, the CPU 61 calculates the rotation angles of the pulse motors M-X and MY corresponding to the amount of movement of the carrier 9 according to the written program, and x, y
X, Y (7) through the motor drive circuit 62 of
% -51M -X, M -Y are driven, thereby the first and second frames 53.56, that is, the carrier 9
are controlled to move in the x and y directions, respectively, and a designated frame image within the plane of the microfiche F held between the transparent plates Gl and G2 is automatically searched and positioned directly below the lens 13. here.

Signals input from the touch panel input section 63 are sent to the CPU 61 as X and Y coordinate positions from a reference point for both the frame stop position input signal and the frame predetermined position input signal.

That is, to position the designated frame image of the microfiche F, input the desired frame, for example "C3" in FIG. Image “C3” is automatically located directly below lens 13.

By the way, due to errors in the photographing position of the microfiche F itself, feeding errors in the transport means, etc., even if the motor rotates for a predetermined number of pulses, the image may be misaligned with respect to the screen as shown in Figure 8 (A). In this case,
The designated frame image "C3" shown in FIG. 8(A) is moved to the predetermined position indicated by the dashed line (in the case of a half-size frame, within the left frame indicated by the dashed dotted line) as follows. That is, first, a changeover switch (not shown) is used to switch the touch panel 8.
0 input mode is specified as the frame stop position input mode as the first input mode, and the searcher selects the specified frame image "C3".
Input one point A indicating the frame stop position into the touch panel 80. Next, use the changeover switch to specify the input mode of the touch panel 80 to the frame predetermined position input mode as the second input mode, and input the point A to the touch panel 80. One point, point B, indicating the predetermined position of the corresponding frame is input into the touch panel 80. Note that the position of point B at a predetermined position of the frame is correlated with the position of point A with respect to the stopped frame "C3".

Then, A(XA, YA

, MY are driven, and the carrier 9 is controlled to move in the x and y directions, respectively, and is positioned at the regular position of °'C3'' shown in FIG. Reading and transcribing the text is called maizō.

The above explanation is based on an example in which point A and point B in FIG. Point) A and point) B may be placed anywhere on the screen 8 as long as they are at the same position in each frame.Furthermore, in the above embodiment, fish film was explained, but in addition to this, roll film and aperture card can be used. Other forms of microfilm such as the above can also be applied to reader printers that are equipped with means for automatically moving the film and means for detecting the distance traveled by the film. Furthermore, in the above embodiment, the touch panel 80 is fixed to the machine box 7;
Furthermore, it may be made detachable from the box 7. If the size of the projected image is known in advance and the print size is also determined, when the coordinates of the image projected on the screen are input, a comparison calculation is performed with the coordinates set in advance from the print position. , if the position of the microfilm is configured to be controlled, it is no longer necessary to input the coordinates anew by simply specifying the predetermined coordinates of the projected image.

(Effects of the Invention) The reader printer according to the present invention has the above-described configuration and operation, and the input panel arranged on the screen can input coordinates on the screen, and the coordinates are input to the input panel by the recognition means. The coordinate data of the information recording medium is recognized, and the amount of coordinate movement is calculated between the first input mode, which indicates the coordinates of the image projected on the screen, and the second input mode, which indicates the coordinates to be moved next. Since the position is controlled by a control means, even if the image position on the information recording medium deviates from the predetermined position, the predetermined position can be inputted into the input panel arranged on the screen, and the image can be accurately and automatically This has the effect of being able to correct positional deviations.
