Abstract

PURPOSE:To eliminate accumulation of returning errors of an image rotating means produced at every copying time so as to prevent the inclination of a copied picture from being increased, by providing a picture rotation inhibiting means which inhibits the actuation of a picture direction control means. CONSTITUTION:At the time of multi-print, retrieving operations are carried out at every page and multi-print mode instructing signals and print signals are transmitted from the control system of a microfiche moving mechanism to the control system of a reader/printer main body. In addition, print busy signals are transmitted from the control system of the reader/printer main body to the control system of the mechanism. However, an image rotating motor is driven only in the normal direction at the moment when the retrieval of a first page is completed and the driving of the motor is inhibited during the period of multi-print mode thereafter. The motor is driven in the opposite direction after printing of the last page is completed. Therefore, returning errors are not accumulated and copied pictures never incline, but can be copied in normal attitudes even when numerous pages are printed.

Description

[Detailed description of the invention] One minute above the cliff! The present invention relates to a reader printer that selectively projects an original image on a microfilm onto a screen and a copy photosensitive surface for reading or copying, and in particular, when the image appearing on the screen is horizontally long, the image is rotated by 90''. The present invention relates to a reader printer with an image rotation function that allows copies to be made on vertically long paper.

The images on the Jubeiza Ibaradama microfilm include those that are printed vertically and those that are printed horizontally. There is no problem when copying the former image onto vertically long paper, but when copying the latter image onto vertically long paper, both ends of the image will not be copied as is. Conventionally, there are printers equipped with image rotation means for copying such a horizontally oriented image onto a vertically oriented sheet of paper.

According to such a reader printer, no matter whether the image imprinted on the microfilm is vertically or horizontally oriented,
When copying, the operator simply operates a switch to select either portrait or landscape images depending on the orientation of the image, and there is no need to rotate the film carrier, making it extremely easy to operate. (Multiple copies of one original) If the original image is horizontally 1
Since the image is rotated once every time a sheet is copied, the copying speed is slow, and the return error of the image rotation means is accumulated each time a copy is made, and as the number of copies increases, the tilt of the copied image increases. There is a problem with becoming.

By the way, recently there has been an increasing need for so-called continuous page break copying, in which multiple pages on microfilm are successively copied, and the above-mentioned league printer is used for this purpose. However, in that case, problems similar to those of multi-copy would arise, so there is an urgent need to solve them.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a new league printer that is designed to avoid the above-mentioned problems when copying continuous page breaks.

In order to achieve the above-mentioned object of increasing the fortune-telling to "1", the present invention provides a reader printer that switches between projecting an original image on a microfilm onto a screen and a photosensitive surface for copying, and directs the projected image to the optical axis for reading or copying. an image rotating means for rotating the image by 90 degrees in the clockwise direction;
An image orientation control means that rotates the microfilm by 0 degrees, and when different pages of microfilm are successively copied, the operation of the image orientation control means is permitted only when copying the first page, and when copying of the first page is started, the image orientation control means is rotated by 90 degrees. The apparatus is characterized in that it includes an image rotation inhibiting means for prohibiting the operation of the image orientation control means after the image rotation is performed by 90 degrees and until the rotation is returned to 90 degrees after the last page is copied.

The operation of the present invention will be explained in detail in Examples.

Figure 1 shows, as an example of the present invention, a league printer main body 2 that uses a micro-finish film and has a screen l in the center, and a printer that has a large number of images imprinted on it. It consists of a microfish moving mechanism 3 that moves the microfish F vertically and horizontally, and a controller section 5 that is connected to the microfish moving mechanism 3 via a cable 4. FIG. 10 shows a microfiche F applied to the reader printer of this embodiment.

In the figure, Pl, Pz, . . . are images of each frame, which are arranged and imprinted in a matrix. Each frame p...
p, . . . are specified by specifying the row (Y-axis address=A, B, . . .) and column (X-axis address=1.2, . . .). In the illustrated example, the Y axis is 7 lines from A to G,
The axes have 14 rows numbered 1 to 14, but the most popular one is the Y-axis with 15 rows and the X-axis with 18 rows.

Further, in FIG. 1, the league printer is equipped with a projection optical system 6 having an AIR function.

The structure of the projection optical system 6 will be explained in detail after the microfiche moving mechanism 3. 7 is an insertion slot for inserting the microfiche F, 8 is an operation panel for selecting the format of the microfiche, switching positive/positive/negative/positive, etc., and 9 is an image for appropriately rotating the image projected on the screen L. The rotary switch 10 is a power switch.

As shown in FIG. 2, the microfiche moving mechanism 3 includes an
It consists of

Specifically, the X-Y carrier section 11 includes a first moving table 13, a first linear pulse smoke 14 that transports the first moving table 13 in the direction of arrow X, and a second moving table. 15, a second linear pulse smoke 16 whose one end is placed on the first moving table 13 and transports the second moving table 15 in the direction of the arrow Y; It consists of a mounted X-Y carrier body 17 and a sliding plate 18 whose upper surface is coated with Teflon and supports the other end of the X-Y carrier body 17. Reference numeral 19 denotes a notch for image projection, which is formed in a semicircular shape so that its center coincides with the projection optical axis.

Furthermore, the XY carrier main body 17 includes a carrier case 21 having a substantially U-shape in plan view and having a recess 20 formed therein;
The holding part 22 is attached to the recess 20 and holds the microfiche F. Further, the lower surface of the carrier case 21 is coated with Teflon,
It is configured to easily slide on the sliding plate 18.

Further, 30... is a sponge backing, which is interposed to prevent the lower glass 24 and the plate springs 28 from coming into rigid contact. and upper glass 23
The position of the lower glass 24 is determined by adjusting the center screws 27 so that the upper surface and the upper surface of the carrier case 21 are flush with each other.

Further, a stepped portion 31 is formed on the lower glass 24, so that even if the microfiche F is inserted between the upper glass 23 and the lower glass 24, it will not be caught between the lower glass 24 and the carrier case 21. It is configured so that it does not.

The X-Y carrier main body 17 configured in this way has a fourth
As shown by the imaginary line in the figure, even if the upper glass 23 is rotated in the direction of arrow C and the microfiche F is inserted from the direction of the arrow, the support 25 acts as a stopper and the microfiche F is held in a predetermined position. Furthermore, the upper surface of the holding part 22 and the upper surface of the carrier case 21 are flush with each other, so that the microfiche F held by the holding part 22 is not tilted with respect to the projection optical axis, and can be projected onto the screen with high precision. becomes possible. Furthermore, since the stepped portion 31 is formed on the lower glass 24 as described above, the microfiche F is not pinched between the lower glass 24 and the carrier case 21, and therefore there is no need to attach or remove the microfiche F. This does not cause any trouble and is suitable for search work.

As shown in FIG. 6, the loading block 12 includes a base 32, a drive motor 33 attached to the base 32, and a drive shaft 36 interlocked with the drive motor 33 via a belt 34 and a pulley 35. , a lifting lever 37 that lifts the upper glass 23 upward.

Reference numerals 1a and 41b denote a pair of left and right guide roller portions that guide the movement of the microfiche F, and include arm portions 42a and 42b whose proximal ends are attached to the base 32, and a pair of guide roller portions 1a and 41b that are fitted into the tips of the arm portions 42a and 42b. It consists of guide roller bodies 43a, 43b attached to the guide roller bodies 43a, 43b, resin ring members 44a, 44b covering the tips of the guide roller bodies 43a, 43b, and guide members 45a, 45b attached to the base. Coil springs 46a and 46b resiliently bias the arm portions 42a and 42b in the direction of arrow E. Also 47a......4
7f is an O-ring that is fitted onto the drive shaft 36, and by not touching the entire surface of the microfiche but partially touching it, the difference in pressure between 44a and 44b or the difference in posture when inserting the film can be reduced at the end of feeding. This is to reduce the frictional part with the film and facilitate the insertion and removal of the microfiche F in order to make it easier to correct the posture.

48 is a first loading sensor, and 49 is a second loading sensor, which detects insertion of the microfiche F. Generally Microfi Nosh F
When inserted into a search device such as a league printer, it is not necessarily inserted from a right angle to the insertion lower (see Figure 1), but is often inserted from an oblique direction, especially if the operator is inexperienced. Sometimes. Therefore, in this embodiment, a pair of loading sensors 48, 49 are provided on the left and right, and the loading sensors 48, 49 are connected to the drive motor 3.
3, the tip of the microfiche F is held in the holding part 2.
After the fish carrier comes into contact with the support tool 25 (see FIG. 4) of No. 2, the drive motor 33 is driven until the fish carrier is sufficiently separated from the home position. Therefore, even if one end of the microfish F comes into contact with the support 25, the drive motor 33 is in the driving state when the other end does not come into contact with the support 25, so the microfish F cannot be stopped in an oblique state. Without fail, both left and right ends come into contact with the support 25 and stop.

Next, the principle of operation of the microfiche moving mechanism 3 will be explained with reference to FIG. 2.

First, the controller unit 5 is operated to move the XY carrier main body 17 to the home position (position where microfiche can be inserted), and the tip of the lifting lever 37 is engaged with the upper glass 23.

Whether or not the XY carrier main body 17 is at the home position is detected by a home position sensor (not shown). Next, the solenoid 40 is turned on and the lifting lever 37 is operated to lift the upper glass 23 upward. When the microfiche F is inserted from the insertion lower (see Figure 1), the first loading sensor 48 detects it, then the second loading sensor 49 detects it, and at the same time, the drive motor 33 rotates in the direction of arrow G. A microfiche F is inserted between the upper glass 23 and the lower glass 24. When the microfifty 1F comes into contact with the support 25, the solenoid 40 is turned off and the lifting lever 37 is lowered, and the upper glass 2
3 also lowers to sandwich the microfiche F between the upper glass 23 and the lower glass 24. Then, after a certain period of time has elapsed, the second linear pulse smoke 16 is driven to move the X-Y carrier body 17 in the direction of arrow Y to separate the X-Y carrier body 17 from the loading block 12;
After that, the drive motor 33 stops.

Thereafter, desired information can be searched by appropriately operating the controller section 5.

Furthermore, when removing the microfish F from the microfish moving mechanism 3, the controller section 5 is operated in the same manner to move the XY carrier main body 17 to the home position. When the X-Y carrier main body 17 is set at the home position, the solenoid 40 turns ON and the lifting lever 37 operates to lift the upper glass 23. Then, by driving the drive motor 33, the microfiche F is removed from the microfiche moving mechanism 3. Confirmation of detachment of the microfiche F can be easily detected by the first loading sensor 43 and the second loading sensor 44. Finally, after a predetermined period of time has elapsed, the drive motor 33 stops, and the series of operations ends.

FIG. 7 shows an example of the controller section 5. As shown in FIG. In the figure, 50 is a Y-axis address key for specifying the Y-axis address of the microfiche F, and 51 is an X-axis address key for specifying the X-axis address. Further, 52 is an eject key, which connects the first linear pulse smoke 14 and the second
The XY carrier main body 17 is moved to the home position by driving the linear pulse smoke 16, and the microfiche F can be removed from the film moving mechanism 3. 53 is a print key for commanding the copying operation; 54
55 is a start key for instructing to start the search; 55 is a fine adjustment/frame advance key; 56 is a fine adjustment/frame advance selection key for selecting whether the fine adjustment/frame advance key 55 is to be set in fine adjustment mode or frame advance mode; 57 is a fine adjustment/frame advance selection key. Memory key for storing input addresses and performing various memory operations; 58 is an index key for selecting and instructing the index recorded on the microfiche F; 59 is for selecting and specifying the mode registered in each formant of the microfiche F. mode selection key. Further, 60 is an indicator light such as a light emitting diode that indicates that the XY carrier main body 17 is at the home position, and indicates whether or not the microfiche F can be inserted.

Reference numeral 61 is a display section, in which the Y-axis address key 50,
Axis address key 51. The items specified by the index key 58, mode selection key 59, etc. are displayed.

FIG. 8 shows an outline of the projection optical system. In the figure,
81 is a light source, 82 is a condenser lens, and 83 is a reflection mirror. Light from the light source 81 is made into parallel light by the condenser lens 82, reflected upward by the reflection mirror 83, and irradiated onto the microfiche F. The light transmitted through the microfiche F passes through a projection lens 84 and an image rotation prism 85, is reflected by a reader mirror 86, and is projected onto a screen (not shown). In order to copy a horizontally long image onto a vertically long sheet of paper, the image rotation prism 85 must be rotated 450 degrees to rotate the image 90'' as shown in FIG. 3(b).

This operation is performed by driving the pulse motor 87. That is, a gear 88 is attached to the rotating shaft of the pulse motor 87.
is provided, and this gear 88 meshes with a gear 90 carved on the circumferential surface of the cylindrical holder 89 that accommodates the image rotation prism 85, so that by supplying an appropriate number of SIX motion Hals to the pulse motor 87, , gears 88, 90, and holder 89, image rotating prism 85 is rotated. Incidentally, image orientation control means for automatically rotating the orientation of a projected image to a predetermined orientation is known from Japanese Patent Application No. 17826/1983 proposed by the present applicant.

FIG. 11 shows a system configuration for controlling the reader printer. The system is the control system 10 of the reader printer main body 2.
1 and the control system 102 of the microfiche moving mechanism 3
The two control systems 101 and 102, which are equipped with two control systems 101 and 102, are interconnected through an interface 103. Both control systems 101 and 102 are microcomputers 104 and 10.
5, ROM 106, 107, RAM 108, 109, and the reader printer main body side control system 101 has input ports of the microcomputer 104 including various timing sensors 110, print switches, sheet count key, negative/positive/positive/ Input key 11 for positive switching key, etc.
1 is connected to the output port, and a drive equipment group 112 such as a main motor, a developing motor, and a solenoid, a charger,
Controlled equipment 113 such as a static elimination charger and a developing bias;
Display devices 114 such as a number display and various LEDs are connected. On the other hand, the control system 102 of the three microfiche moving mechanisms includes a sensor group 115 such as a loading sensor, home position sensors for the X and Y axes, a numeric keypad, a memory key, a mode key, and a memory key for the three microfiche moving mechanisms. A group of input keys 116 such as keys, print keys, start keys, etc. are connected, and the output port is connected to the
It is connected to a driving equipment group 117 such as a Y-axis stem motor and a loading motor, a display group 118 such as a fine adjustment/feed LED, and a home position sensor, and a group of input keys 116. An interface 103 that connects the two control systems 101 and 102 transmits a predetermined control signal from one control system to the other during a search in reader mode, a search in print mode, printing, and the like. For example, in so-called multi-printing, in which multiple pages imprinted on microfiche are printed, a signal instructing the multi-print mode from the control system 102 of the microfiche moving mechanism 3 to the control system 101 of the reader printer main body 2 and a print signal and conversely, the latter control system 10
1 transmits a print busy signal to the former control system 102. The print busy signal is a signal that prohibits movement of the microfiche moving mechanism so that it does not unexpectedly move in response to other signal input during printing. 12th
The figure is a time chart explaining these signals and necessary operations during multi-printing. As shown in the figure, when the multi-print mode is activated, a search operation (Figure (A)) is performed for each page, and a print signal (Figure (C)) is performed for each page.
) is transmitted between control systems. Then, a copying operation (FIG. (E)) is performed on the reader printer main body side 2, and a print busy signal (FIG. (E)) is transmitted between the control systems.

However, the image rotation motor is only driven in the normal direction when the search for the first page is completed, as shown in FIG. and,
After printing the last page, it is driven in reverse. The image rotation motor is driven by A, and the image is rotated by the IR function.
Since a 0° rotation action is performed, during multi-printing, the image is rotated 90'' before printing the first page, and the image is rotated 90'' in the opposite direction after printing the last page. Incidentally, since the image rotation motor is driven when the above-mentioned image direction control means determines that the image imprinted on the microfiche is horizontally long, the time chart in FIG. FIG. 4 is a diagram illustrating multi-printing when a microfush with a vertical image imprinted thereon is applied, and image rotation is not performed as in the same figure when a microfush with a vertically long image imprinted is applied.

FIGS. 13 and 14 are flowcharts illustrating the operation of the system shown in FIG. 11 when a microfiche on which a horizontally long image is imprinted is applied. Of these, FIG. 13 is a diagram explaining the operation of the reader printer main body side, and FIG. 14 is a diagram explaining the operation of the microfiche moving mechanism side.

First, on the reader printer main body side, after checking the reception of the key input in step 1, it is determined in steps 2 to 4 whether the pressed key is a print key, another key, such as a function key, or a clear key. For keys other than the print key, the process is completed by performing predetermined processing as shown in the figure. On the other hand, if the print key is pressed, it is checked in step 5 whether or not a multi-print signal has been input from the microfiche moving mechanism 3 side, and if a multi-print signal has been input, the control system is set to multi-print. The multi-flag is turned on to set the mode (step 6). On the other hand, if the multi-print signal is not input, the multi-flag is turned off (step 7).

Furthermore, regardless of whether or not a multi-print signal is input, when the print key is pressed, a print busy signal is transmitted to the control system 102 of the microfiche moving mechanism 3 (step 8
), then it is determined whether the AIR flag in the memory is on (step 9). AIR flag is AIR
The function turns on when the 90" image rotation (normal rotation) is completed, and turns off when the 90° rotation is reversed. Therefore, if the AIR flag is not on, proceed to step 10 and perform the process of 90" image rotation. After doing so, the AIR flag is turned on in step 11. If the AIR flag is turned on, the process advances to step 12 and a print subroutine is executed. This subroutine shows processing when only one sheet is printed. Therefore, once printing of one sheet is completed, the process advances to step 14 via step 13, and it is determined whether the multi-flag is on. When the multi-flag is off from the beginning, that is, when only one image is to be printed, the process proceeds to step 15, where the image rotation motor is rotated in the reverse direction, and then the AIR flag in the memory is turned off at step 16. Further, in step 17, the print busy signal is stopped, and the process returns to step 1.

On the other hand, when using multi-print, the number of remaining prints is 1.
Since the multi-flag is on until the number of sheets is reached, the process directly proceeds from step 14 to step 17, and the print busy signal is turned off. Then, the process returns to step 1, and the above operations are repeated until the specified number of bones have been printed. However, when printing the first sheet, A is selected in step 11.
Since the I flag is on, subsequent printing up to the specified number of sheets does not go through step 10.
Therefore, no image rotation processing is performed. When the designated number of sheets is reached, it is confirmed in step 14 that the multi-flag is turned off, so the image rotation motor is reversed in step 15, and then the AIR flag is turned off (step 16).

After this, turn off the print busy signal (Step 17)
, return.

Next, the control system 102 of three examples of microfiche moving mechanisms
Then, in step 20, the key input is accepted, and in steps 21 to 24, the Y-axis address specified by the Y-axis address key is stored in DBy+ of the ring counter, and the X-axis address D0 specified by the X-axis address key is stored. Store in °. At this time, if there is an arrow key input (step 25)
, D(IX) The address stored in D(1y, Search for the frame specified by D(lY,).

On the other hand, if the start key is not input but the print key is input, steps 28, 29, 30, 31, 3
Proceed to step 2, after searching for the specified frame, send a print signal to the league printer main body side, and when the print busy signal turns OFF, it is assumed that printing is completed and return. Also, if the start key or print key is not pressed but the memory key is pressed, step 3
3. The process advances to step 34 to perform a process of storing the designated address. If the clear key is pressed instead of the memory key, the process advances to steps 35 and 36' to clear the memory contents.

On the other hand, when an arrow key input is detected in step 25, it is determined that the previous address key input is the start address, and the process proceeds to step 37, where the next key-in input is accepted. When the Y-axis address key and the X-axis address key are input, the final address is stored in D(t) and D(2V) of the ring counter in steps 38 to 41. If is pressed, the process advances to steps 42 and 43 and the start address D (IXI
D (IY) to final address D HX) D (t
A page-turning search is performed in which each page up to VI is sequentially searched.

If the print key is pressed instead of the start key, processing from step 47 onwards is performed.

This operation will be described later. On the other hand, if the clear key is pressed, the process advances to steps 45 and 46 to clear the data.

When it is detected in step 44 that the print key is pressed, the process advances to steps 47 and 48, and the start address D (IY) stored in the ring counter is the final address D <zx> D (2Y) If they match, it is determined that there is only one print, and steps 29 to 3 described above are performed.
Perform processing up to 2. On the other hand, if the start address and the final address do not match, it is determined that multi-printing is being performed, and the processing from step 49 onwards is performed. That is, first,
In step 49, the ring counter D (IX) D (
After searching for a frame corresponding to the start address stored in IY), it is confirmed that the search address is not the final address, and then the process proceeds to step 52, where D(IX) is incremented by one. In this case, D after incrementing
lX.

If it is not the last column (19) of the same row, the process proceeds directly from step 53 to steps 56 and 57, and the multi-print signal and print signal shown in FIG. Then, after the print busy signal on the league printer main body side is turned off (step 58), if the print busy signal is turned off, the process returns to step 49 to perform the search. This search is performed for the frame whose address is incremented in step 52. After the search, D(1x) is incremented by one in step 52, and then the same operation as above is performed. If the above operation is performed up to the last column (=19) of the same row, the process proceeds from step 53 to step 54.55, where D(lX, is set to 1 and DHy+ is incremented by 1. As a result, the next row Print one page at a time from the first column of .Then, address D (IX) D where the search was completed
If it is detected in steps 50 and 51 that (1) matches the final address (DHX)DHY), the process advances to step 63 and the search over flag is turned on. After that, the final page is printed by advancing through steps 56, 57, and 58, and the print signal is changed to 0FFL and 0FFL at step 61.
Proceeding to step 60, the multi-print signal is turned off.

In this way, multi-printing is completed and the machine returns.

According to the reader printer according to the present invention as described above, when a plurality of images imprinted on microfilm are continuously copied, the frame images are images imprinted in a horizontally long manner, When copying it onto portrait paper, the image is rotated by 90'' only once before copying the first page, and the image rotation means is fixed until the final page is copied. Unlike the conventional means of rotating the image each time it is printed, there is no accumulation of return errors, and therefore, even when printing multiple pages, the copied image does not tilt and can always be copied in its normal orientation. There is.
