Description

The present invention relates to an image observation recording device such as a reader printer, more specifically, an image observation recording device provided with a search device for high density information recording media such as microfilm and microfiche. Regarding

(Prior Art) Conventionally, as an apparatus of this type, there is an apparatus including a search device that searches for a desired image and forms it on a screen, and a copying device that copies the image. It is adapted to operate independently of the device. The above-mentioned retrieval device repeats the operation of intermittently displaying an image on the screen for a predetermined time for a plurality of images by an intermittent frame feeding mechanism that intermittently sends image frames such as microfiche according to a predetermined order, It has a so-called "browsing search" function.

Then, when searching for microfish, etc., the image frames are sequentially projected on the screen by the intermittent frame feeding mechanism,
This is done by visually inspecting each image. Therefore, when it is desired to obtain a copy of a desired image frame, the intermittent frame feeding mechanism is stopped while the image frame is projected on the screen, the print button is pressed to obtain a copy, and then the intermittent frame is again reproduced. It started to send by key operation and continued to search.

(Problems to be Solved by the Invention) However, in the case of such a conventional technique, in order to copy an image frame during a search by intermittent frame feeding, the intermittent frame feeding mechanism is stopped immediately and the print button is pressed to perform copying. After that, the key operation must be performed again to start the intermittent frame feeding, which causes a problem that the operability is extremely poor. In addition, when the print button is pressed to make a copy without stopping the intermittent frame feeding mechanism, frame feeding is performed during copying, resulting in an incomplete copy.

Therefore, the present invention has been made in order to solve the above-mentioned problems of the prior art, and an object of the present invention is to repeatedly perform an operation of projecting an arbitrary image on a screen for a predetermined time for a plurality of images. Another object of the present invention is to provide an image observation recording apparatus capable of copying only a desired image with a simple operation.

(Means for Solving Problems) In order to achieve the above object, the present invention projects an image of an information recording medium having a large number of image frames and marks corresponding to these image frames on a screen. In the image observation recording apparatus for observing the image and recording the image by the image recording means as needed, the image is projected manually on the image projected on the screen, and a print signal is generated by this operation. A print command means and an arbitrary image frame among a large number of image frames on the information recording medium are conveyed to a projection position, stopped by detecting a mark, and the arbitrary image frame placed at the projection position is displayed on a screen. After the image is projected and stopped for a certain period of time, a search unit that sequentially repeats the operation of transporting the next image frame to the projection position, and an arbitrary image frame is searched by the search unit. When a print signal is output from the print command means while stopped at the projection position, the operation of the search means is temporarily stopped, the image recording means is operated, and then the recording operation by the image recording means ends. And a search record control means for restarting the operation of the search means.

(Example) Hereinafter, the present invention will be described based on illustrated examples. In FIG. 2 and FIG. 3, reference numeral 1 denotes a reader printer, and the reader printer 1 generally forms an image frame of a microfish F as an information recording medium selectively on a screen 2. , The optical device 4 for forming an image on the photoconductor 3, and the microfish F
Retrieval device 5 as a retrieving means for driving the above, and a copying device 6 as an image recording means for obtaining a duplicate of a desired image.
It consists of

The optical device 4 is provided with a light source 7 for film irradiation, and a light beam from the light source 7 for film irradiation is applied to the microfish F through the condenser lens 8 and the field lens 9 and passes through the microfish F. The image light is projected on the screen 2 via the projection lens 10 and the mirrors 11 and 12. Also, Microfish F
Image light is also projected onto the photosensitive drum 3 of the copying apparatus 6 via the scanning half mirrors 13 and 14.

The copying machine 6 records an image by an electrophotographic process by operating a button (not shown) as a print command means, and the developing device 15 and the like around the photosensitive drum 3 are integrally incorporated. The cartridge 16 is installed. Reference numeral 17 is a pre-electrification exposure lamp, 18 is a transfer charger, 19 is a copy paper cassette, 20 is a register roller, 21 and 22 are paper feed rollers, and 23 is a fixing device.

Further, as shown in FIG. 3, the search device 5 includes a base 24, and a screw screw 27 is rotatably mounted between a pair of side walls 25 and 26 of the base 24 facing each other. A guide shaft 28 is installed in parallel with the screw screw 27. An X-direction carrier table 29 having one end screwed into a screw screw 27 and the other end supported by a guide shaft 28 is attached to the base 24.
The pulse motor 29 can be slid in the X direction by rotating the screw 27 with the pulse motor 30. This X
A screw screw 31 is rotatably mounted on the direction carrier table 29, and a guide shaft 32 is installed in parallel with the screw screw 31. One end of the X-direction carrier table 29 is screwed into a screw screw 31, and the other end thereof is supported by a guide shaft 32, which is a Y-direction carrier table 33.
The Y-direction carrier table 33 is slidable in the Y-direction by rotating the screw screw 31 with the pulse motor 34. This Y-direction carrier table 33 holds the microfish F 1
It is provided with a pair of glass plates g ₁ and g ₂ , and the upper glass plate g ₁ can be opened and closed.

FIG. 1 is a block diagram showing the control circuit of the search / copy control means of this embodiment. Reference numeral 35 is a reference oscillation circuit that serves as a reference for time measurement, 36 is a counter for measuring time, 37 is a digital switch for setting the frame advance interval of intermittent frame advance, 38 is a comparator, 39 is a pulse generator circuit for intermittent frame advance, 40 Is a motor drive circuit that drives the pulse motor 30 by the output of the pulse generation circuit 41 and the search direction signal 42. Further, 43 is an RS flip-flop circuit, 44 and 45 are AND circuits, 46 is an OR circuit, and 47 and 48 are knot circuits.

With the above configuration, the image observation recording apparatus according to the present invention operates as follows. That is, as shown in FIG.
Set Microfish F between the glass plates g ₁ and g ₂ ,
When intermittently searching the image frames of the microfish F in a predetermined order, an intermittent search key (not shown) is operated. Then, when the intermittent search signal 49 becomes "H", "L" is input to one of the OR circuits 46 via the knot circuit 47, but at this time, the output 50 of the comparator 38 is also "L". The reset signal 51, which is the output of the OR circuit 46, becomes "L", and the counter 36 starts the counting operation of the pulse from the reference oscillation circuit 35. Since the output of the comparator 38 is "L" at this time, one input of the AND circuit 44 is "H" via the knot circuit 48.

The count value of the counter 36 is compared with the set value of the digital switch 37 by the comparator 38, and when both values match, the match signal 50 becomes "H". When not printing, RS
Since the flip-flop 43 is reset, the output 51 of Q is "H" and the output 52 of the AND circuit 44 is "H".
Then, the pulse generating circuit 39 is activated. The pulse generation circuit 39 generates the pulse output 41 by the number of pulses required to move the X-direction carrier table 29 to the next image frame, and passes through the motor drive circuit 40 and the pulse motor.
Drive 30 in the direction determined by the search direction signal.
Further, since the output of the AND circuit 44 becomes "H", the counter 36 is reset by the reset signal 51 input through the OR circuit 46, and accordingly, the output of the comparator 38 becomes "L". Therefore, the output of the AND circuit 44 becomes "L" and the reset signal 51 of the counter 36 becomes "L" again. This operation is repeated thereafter, and the microfish is driven intermittently in the X direction until the intermittent search button is turned off.

Next, when copying the image of the searched image frame, while the desired image is projected on the screen 2,
A print button (not shown) is pressed and copying is performed by the copying apparatus 6 by an electrophotographic process. Then, when the print signal 53 becomes “H”, the RS flip-flop
43 is set, the input 51 of the AND circuit 44 becomes "L",
The output 50 of the comparator 38 is not transmitted to the pulse generation circuit 39, so that the intermittent search operation is stopped. Further, when the output 50 of the comparator 38 becomes “H” in this state, the signal 54 via the knot circuit 48 is input to the AND circuit 45, and the input pulse to the counter 36 is also cut off. ,
The counter 36 stops at the value set in the digital switch 37, and the output 50 of the comparator 38 also maintains "H".

Next, when the printing of the required number of copies is completed, the print completion signal 55 becomes "H", the output 50 from the comparator 38 is input to the pulse generation circuit 39, and the pulse generation circuit 39 is restarted.
39 generates the pulse required for the search. Also the counter
After being once reset, 36 starts counting and restarts the intermittent frame feeding operation as described above. In the above description, the search in the X direction has been described, but the search in the Y direction is performed in exactly the same way.

In this embodiment, the print signal 53 allows the comparator
Since the output 50 from the 38 to the pulse generation circuit 39 is turned on and off, and the output 50 of the comparator 38 remains "H" during printing, the counter 36 stops counting and waits. Simultaneously with the end, the output 50 of the comparator 38 is input to the pulse generating circuit 39, the motor drive circuit 40 operates, and the intermittent search operation is restarted. Therefore, the next intermittent search operation can be performed at the same time as printing is completed.
The loss of search time can be eliminated.

In the illustrated embodiment, the output 50 from the comparator 38 to the pulse generation circuit 39 is turned on / off by the print signal 53, and the counter 50 is kept in the state where the output 50 of the comparator 38 is "H" during printing. The case where the count of 36 is stopped and the waiting is explained. However, the present invention is not limited to this, and a simple configuration in which the count operation of the counter is stopped during the print operation is also possible. In this case, the counter restarts the count when the print is completed, and the count value becomes the predetermined value. The next search operation does not start until the value of is reached.

Further, when an information recording medium such as a microfiche is driven by a DC motor for searching, the driving of the motor may be turned on / off by a print signal.

Further, in the illustrated embodiment, the case where the microfiche is used as the information recording medium has been described, but the present invention is not limited to this, and it is needless to say that the invention can be applied to an apparatus for searching a roll-shaped microfilm.

Further, in the illustrated embodiment, the case where the searched image is copied as the recording operation has been described, but the present invention is not limited to this. When the searched image is read by the CCD element and recorded on the optical disk, etc. Of course, it can also be applied to.

(Effects of the Invention) As described above, according to the present invention, the operation of projecting an arbitrary image on the screen for a fixed time is repeated for a plurality of images to find an image to be printed,
Since you can select and copy only the images you need,
While sequentially observing the images, it is possible to copy the selected image frames with a very simple operation.
