Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reader printer for projecting an original image on a microfilm by switching and projecting it on a screen and a photoconductive surface for reading or copying, and particularly, it appears on the screen. The present invention relates to a reader printer with an image rotation function, which rotates an image 90 ° in the horizontal direction and copies it on a vertically long sheet by rotating the image 90 °.

2. Description of the Related Art Images on a microfilm include a vertically long image and a horizontally long image. There is no problem when the former image is copied onto the vertically long paper, but when the latter image is copied onto the vertically long paper, both ends of the image are not copied as they are. Conventionally, there is a printer provided with an image rotation means for copying an image thus printed in landscape orientation on portrait paper.

With such a reader printer, regardless of whether the image printed on the microfilm is portrait or landscape, the operator operates the switch to select the portrait image or the landscape image depending on the orientation of the image during copying. It is not necessary to rotate the film carrier just by performing the operation, and the operability is very excellent. On the other hand, in the case of multi-copy (copying one original sheet), if the original image is horizontally long, 1 Since the image is rotated once every time one copy is made, the copying speed becomes slower, and the return error of the image rotating means at the time of each copying is accumulated, and the inclination of the copied image becomes large as the number of copying increases. There is a problem of becoming.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention Recently, there is an increasing need for so-called continuous page-break copying in which a plurality of pages on a microfilm are continuously copied, and the reader printer described above is used for this purpose. However, in that case, the problem similar to that of multi-copy arises, and its solution is urgent.

Therefore, an object of the present invention is to provide a new reader printer devised so that the above-mentioned problems do not occur when continuous page-break copying is performed.

Means for Solving the Problems In order to achieve the above object, the present invention provides a reader printer for switching and projecting an original image on a microfilm to a screen copy photosensitive surface for reading or copying.
An image rotating means for rotating the projected image by 90 ° around the optical axis and an image rotating means for detecting whether the projected image on the screen is vertically long or horizontally long and copying the horizontally long image to a vertically long transfer paper by 90 °.
In the case where different pages of the microfilm are continuously copied, the image orientation control means for rotating the image orientation control means is allowed only when the first page is copied, and the image orientation control means is operated at 90 ° when the first page is copied. The image circuit inhibiting means for inhibiting the operation of the image orientation control means is provided after the image is rotated and after the final page is copied until it is rotated by 90 °.

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

EXAMPLE FIG. 1 shows, as an example of the present invention, a reader / printer to which a microfiche film is applied, in which a reader / printer main body 2 having a screen 1 in a central portion and a microfiche F having a large number of images imprinted thereon. And a controller unit 5 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, P ₁ , P ₂ ... Are images of each frame, and are arranged and imprinted in a matrix. Each frame P ₁ , P ₂ , ... Is specified by specifying a row (Y-axis address = A, B, ...) And a column (X-axis address = 1,2 ...). In the illustrated example, the Y axis is A to G
There are 14 lines on the X axis and 1 to 14 on the X axis, but the popular ones are 15 lines on the Y axis and 18 lines on the X axis.

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

It comprises an XY carrier body 17 whose one end is conveyed to the second moving table 15 and a slide plate 18 which is coated with Teflon on the upper surface and supports the other end of the XY carrier body 17. . Reference numeral 19 denotes a notch portion cut out for projecting an image, which is formed in a semicircular shape so that the center coincides with the projection optical axis L.

Further, the XY carrier main body 17 includes a carrier case 21 having a recess 20 formed therein and having a substantially U-shape in a plan view, and a holding portion 22 attached to the recess 20 for holding the microfish F. Consists of. The above carrier case 21
Teflon coating is applied to the lower surface of
It is configured to be easy to slide with 18.

As shown in FIGS. 3 and 4, the holding portion 22 has an upper glass 23, a lower glass 24, and a supporting member 25 fixed to the upper glass 23 as main parts. Further, a pair of left and right pins 26a, 26b is projected from the support 25, and
The upper glass 23 is placed on the carrier case 21 via 6a and 26b. Further, the lower glass 24 is, as shown in FIG.
A plurality of height-adjusting set screws 27... Arranged at appropriate places near the recess 20 of the carrier case 21;
... and a plurality of plate bases 28 provided so as to face each other. Denoted at 29 are fixing members for fixing the springs 28 to the carrier case 21. Further, 30 is sponge packing and is interposed to prevent the lower glass 24 and the leaf springs 28 from coming into rigid contact with each other. The position of the lower glass 24 is determined by adjusting the set screws 27 so that the upper surface of the upper glass 23 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, and the microfish F is attached to the upper glass 23.
It is configured so that it will not be sandwiched between the lower glass 24 and the carrier case 21 even if it is inserted between the lower glass 24 and the lower glass 24.

The XY carrier body 17 having such a configuration is
As shown by the phantom 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 arrow D, the support 25 serves as a stopper and the microfiche F.
Fits in place. In addition, the upper surface of the holding portion 22 and the upper surface of the carrier case 21 are flush with each other, and the microfish F held by the holding portion 22 does not incline with respect to the projection optical axis L and is accurately projected on the screen. It becomes possible. Further, since the stepped portion 31 is formed on the lower glass 24 as described above, the microfish F is the lower glass.
Since it is not sandwiched between the carrier 24 and the carrier case 21, there is no problem in attaching and detaching the microfish F, which is suitable for the search operation.

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 that is interlocked with the drive motor 33 via a belt 34 and a pulley 35. A lift lever 37 for lifting the upper glass 23 upward, a roller shaft 38 for fixing the holding bar 37, and a solenoid 40 connected to the roller shaft 38 via a roller arm 39 are provided. 41a and 41b are a pair of left and right guide roller portions that guide the traveling of the microfiche F, and arm portions 42a and 42b whose base ends are attached to the base 32,
Guide roller main bodies 43a, 43b fitted to the ends of the arm portions 42a, 42b in a fitting manner, and the guide roller main bodies 43a, 43b
The resin ring members 44a and 44b covering the tip end of the and the guide members 45a and 45b attached to the base. 46
Reference characters a and 46b are coil springs that elastically urge the arm portions 42a and 42b in the arrow E direction. Further, 47a, ..., 47f are O-rings that are fitted onto the drive shaft 36. By contacting them partially rather than contacting the entire surface of the microfiche, the pressure difference between 44a and 44b, or when inserting the film, This is to reduce the frictional portion with the film and to smoothly insert and remove the microfiche F in order to facilitate the attitude correction at the end of feeding the attitude difference.

Reference numeral 48 denotes a first loading sensor, and 49 denotes a second loading sensor, which is a sensor for detecting insertion of the microfish F. Generally, when the microfish F is inserted into a search device such as a reader printer, the insertion port 7
It is not always inserted in a direction perpendicular to (see FIG. 1), and in particular, when the operator is immature, it is often inserted in an oblique direction. Therefore, in the present embodiment, a pair of right and left rotating sensors 48, 49 are provided, the rotating sensors 48, 49 are interlocked with the drive motor 33, and the tip of the microfish F has the holding member 25 of the holding section 22.
After contacting (see FIG. 4), the drive motor 33 is driven until the fish carrier is sufficiently separated from the home position. Therefore, even if one end of the microfiche F comes into contact with the support tool 25, the other end of the microfish F does not contact the support tool 25.
When it is not in contact with 25, the drive motor 33 is in a driving state, so that the microfish F does not stop in an oblique state, and both left and right ends always contact the support 25 and stop.

Next, the operating principle of the microfish moving mechanism 3 will be described with reference to FIG.

First, the controller unit 5 is operated to move the XY carrier body 17 to the home position (the position where the microfish can be inserted), and the tip of the lifting lever 37 is engaged with the upper glass 23. Whether or not the XY carrier 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 microfish F is inserted from the insertion port 7 (see FIG. 1), the first loading sensor 48 detects it, and then the second loading sensor 49 detects it. At the same time, the drive motor 33 rotates in the direction of arrow C. The microfish F is inserted between the upper glass 23 and the lower glass 24. Then, the microfish F is used as the support 25
, The solenoid 40 turns off and lift lever 3
7, the upper glass 23 is also lowered, and the microfish F is sandwiched between the upper glass 23 and the lower glass 24. Then, after a certain time has passed, the second linear pulse motor
16 is driven to move the XY carrier body 17 in the direction of the arrow Y to separate the XY carrier body 17 from the loading block 12, and then the drive motor 33 is stopped. Then, by operating the controller unit 5 as appropriate, desired information can be searched.

When the microfish F is detached from the microfish moving mechanism 3, the controller unit 5 is also operated to move the XY carrier body 17 to the home position. When the XY carrier body 17 is set to the home position, the solenoid 40 is
When turned on, the lifting lever 37 is actuated to lift the upper glass 23, and then the drive motor 33 is driven to separate the microfish F from the microfish moving mechanism 3. Confirmation of separation of Microfish F is the first
Loading sensor 43 and second loading sensor
It can be easily detected by 44. Finally, after a lapse of a predetermined time, the drive motor 33 stops, and a series of operations ends.

FIG. 7 shows an example of the controller unit 5. In the figure, reference numeral 50 is a Y-axis address key for designating the Y-axis address of the microfish F, and 51 is an X-axis address key for designating the X-axis address. An eject key 52 drives the first linear pulse motor 14 and the second linear pulse motor 16 to move the XY carrier body 17 to the home position, and moves the microfish F from the film moving mechanism 3. It can be detached. 53

1, the one designated by the index key 53, the mode selection key 59, etc. are displayed.

FIG. 8 shows the 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. The light from the light source 81 is collimated by the condenser lens 82, reflected upward by the reflection mirror 83, and applied to the microfiche F. The light transmitted through the microfiche F passes through the projection lens 84 and the image rotation prism 85, is reflected by the reader mirror 86, and is projected on a screen (not shown). To copy a landscape image on portrait paper,
The image rotation prism 85 must be rotated 45 ° to rotate the image 90 ° as shown in FIG. This operation is performed by driving the pulse motor 87. That is, since the rotation shaft of the pulse motor 87 is provided with the gear 88, and the gear 88 meshes with the gear 90 engraved on the peripheral surface of the cylindrical holder 89 that houses the image rotation prism 85, the pulse motor 87 is provided. The image rotation prism 85 is rotated via the gears 88 and 90 and the holder 89 by supplying an appropriate number of drive pulses to the image rotation prism 85. An image orientation control means for automatically rotating the orientation of the projected image to a predetermined orientation in this way is known in Japanese Patent Application Laid-Open No. 60-17826 proposed by the present applicant.

FIG. 11 shows a system configuration for controlling the reader / printer. The system is the control system 101 of the reader / printer main body 2.
And the control system 102 of the microfish moving mechanism 3. Both control systems 101 and 102 are connected to each other by an interface 103. Both control systems 101 and 102 include microcomputers 104 and 105, ROMs 106 and 107, and RAMs 108 and 109, and the reader / printer main body side control system 101 includes various timing sensors 110, print switches, and multiple input keys at the input ports of the microcomputer 104. ,
Negative / Positive / Positive / Positive changeover keys etc. are connected to the input key 111, and the output port is connected to the drive device group 112 such as main motor, phenomenon motor, solenoid, etc. display,
Display devices 114 such as various LEDs are provided. On the other hand, the control system 102 on the side of the microfish moving mechanism 3 has a sensor group 115 such as a rotating sensor and a Y, Y-axis home position sensor at the input port of the microcomputer 105.
And an input key group 116 such as a numeric keypad, a Y-axis key, a memory key, a mode key, a print key, and a start key are connected to each other, and a drive device group 117 such as an X-axis and Y-axis step motor and a loading motor is connected to an output port. It is connected to a display group 118 such as a fine adjustment / feed LED and a home position LED, and an input key group 116. An interface 103 connecting the two control systems 101 and 102 transmits a predetermined control signal from one control system to the other control system during search in the reader mode, search in the print mode, printing, and the like. For example, at the time of so-called multi-printing for printing over a plurality of pages imprinted on the microfiche, a signal and a print signal for 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 conversely, a print busy signal is transmitted from the latter control system 101 to the former control system 102.
The print busy signal is a signal for stopping the movement so that the microfish moving mechanism side does not unexpectedly move by receiving another signal input during printing. FIG. 12 is a time chart explaining these signals and necessary operations during multi-printing. As can be seen from the figure, in the multi-print mode, the search operation (Fig. (A)) is performed for each page, and the print signal (Fig. (C)) is transmitted between the control systems. Then, the copying operation (Fig. (E)) is performed on the reader / printer main body side 2, and the print busy signal (Fig. (F)) is transmitted between the control systems. However, the image rotation motor is normally driven only when the search for the first page is completed, as shown in FIG. 4D, and is prohibited from being driven thereafter in the multi-print mode. Then, after the printing of the last page is completed, it is driven in reverse.
The image rotation motor is driven by the AIR function to rotate the image 90 °, so during multi-printing, the image is rotated 90 ° before the first page is printed and 90 ° in the reverse direction after the last page is printed. The image will be rotated.
The image rotation motor is driven when the image orientation control means described above determines that the image projected on the microfiche is horizontally long. Therefore, the time chart of FIG. 12 shows the horizontally long image. FIG. 11 is a diagram for explaining multi-printing when the microfuse with the imprinted therein is applied, and when the microfiche with the vertically long image imprinted is applied, the image rotation is not performed as in the figure.

13 and 14 are flowcharts for explaining the operation of the system of FIG. 11 when a microfiche with a horizontally long image is applied. Of these, the first
FIG. 13 is a diagram for explaining the operation on the reader printer main body side, and FIG. 14 is a diagram for explaining the operation on the microfish moving mechanism side.

First, after the key input is accepted in step 1 on the reader printer body side, it is discriminated whether the key pressed in steps 2 to 4 is a print key or another key such as a function key or a clear key. If the key is a key other than the print key, the process ends as shown in the drawing. On the other hand, if the print key is pressed, it is confirmed in step 5 whether a multi-print signal is input from the microfish moving mechanism 3 side. If a multi-print signal is input, the control system is multi-printed. To set the mode, the multi-flag is turned on (step 6), while when the multi-print signal is not input, the multi-flag is turned off (step 7). Further, regardless of whether or not the multi-print signal is input, when the print key is pressed, the print busy signal is transmitted to the control system 102 of the microfish moving mechanism 3 (step 8), and then the AIR flag in the memory is turned on. It is determined whether or not (step 9). The AIR flag turns on when the 90 ° image rotation (normal rotation) is completed by the AIR function,
Turns off by reversing 90 °. Therefore, if the AIR flag is not turned on, the process proceeds to step 10 to perform the image rotation of 90 °, and then the air flag is turned on in step 11. A
If the IR flag is turned on, the process proceeds to step 12 and the print subroutine is executed. This subroutine shows a process for printing only one sheet. Therefore, when printing of one sheet is completed, the process proceeds to step 14 through step 13, and it is determined whether or not the multi-flag is turned on. When the multi-flag is off from the beginning, that is,
If you want to print only one sheet, proceed to step 15, rotate the image rotation motor in the reverse direction, turn off the AIR flag of the memory in step 16, stop the print busy signal in step 17, and then Return to.

On the other hand, at the time of multi-printing, since the multi-flag is on until the remaining number of prints becomes one, 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 operation is repeated until printing of the designated number of sheets is completed. However, since the AI flag is turned on in step 11 at the time of printing the first sheet, step 10 is not performed when printing up to the designated number of sheets thereafter, and thus the image rotation processing is not performed. When the specified number of sheets is reached, it is confirmed in step 14 that the multi-flag is off. Therefore, in step 15, after performing the process of reversing the image rotation motor, AI
The R flag is turned off (step 16). After this, the print busy signal is turned off (step 17) and the process returns.

Next, the control system 102 on the side of the microfish moving mechanism 3
Then, after confirming the key input acceptance in step 20, store the Y-axis address specified by the Y-axis address key in steps 21 to 24 in D _(1Y) of the ring counter, and specify the X-axis address specified by the X-axis address key. Store at axis address D _(1X) . If you press the arrow keys this time (step 25), D _(1X) D
_If the address stored in _(1Y) is the start address, but there is no arrow key input and the start key is pressed instead, proceed to steps 26 to 27 and specify with D _(1X) D _(1Y) . Search for the selected frames. On the other hand, if there is no start key input and print key input, step 2
After proceeding to 8,29,30,31,32 and searching for the designated frame, a print signal is sent to the reader printer main body side, and when the print busy signal is turned off, it is considered that printing is completed and the process returns. If the memory key is pressed without pressing the start key or the print key, the process proceeds to steps 33 and 34 to store the designated address. If the clear key is pressed instead of the memory key, the process proceeds to steps 35 and 36 to clear the memory contents.

On the other hand, when the input of the arrow key is detected in step 25, it is determined that the input of the previous address key is the start address, and the process proceeds to step 37 to accept the next key-in input. Then, when the Y-axis address key or the X-axis address key is input, in steps 38-41 the ring counter D
_(2X) Store the final address in D _(2Y) . After this process is completed, if the start key is pressed, steps 42 and 43
To start address D _(1X) D _(1Y) to end address D
_(2X) D _(2Y) The page turning search is performed by sequentially searching each page.

If the print key is pressed instead of the start key, the processing from step 47 onward is performed. This operation will be described later. On the other hand, if the clear key is pressed, step 4
Go to 5,46 to clear the data.

When it is detected in step 44 that the print key is pressed, the process proceeds to steps 47 and 48, where the start address D _(1X) D _(1Y) stored in the ring counter is the final address D _(2X) D.
It is determined whether or not they match with _(2Y), and if they match, it is determined that the prints are the only prints that match, and the processes in steps 29 to 32 described above are performed. On the other hand, if the start address and the end address do not match, it is determined that the printing is multi-printing, and the processes in and after step 49 are performed.
That is, first, in step 49, D _(1X) D _(1Y) of the ring counter
After searching for the frame corresponding to the start address stored in, the search address is confirmed not to be the final address, and then the process proceeds to step 52 to increment D _(1X) by one. In this case, if D _(1X) after incrementing is not the last column (19) in the same row, go directly from step 53.
Proceed to 56 and 57, and issue the multi-print signal and print signal shown in the figure to the reader printer body side. Then, the print busy signal on the reader printer body side is turned off.
After that (step 58), if the print busy signal is turned off, the process returns to step 49 and the search is performed. This search is performed for the frame of the address incremented in step 52. After the search, again in step 52 D
After incrementing _(1X) by one, the same operation as above is performed. If the above operation is performed up to the last column (= 19) in the same row, the process proceeds from step 53 to steps 54,5, D _(1X) is set to 1, and D _(1Y) is incremented by 1.
This prints one page at a time from the first column of the next row. And the address that completed the search D _(1X) D _(1Y)
Matches the final address D _(2X) D _{(2Y) in} step 5
If detected at 0 and 51, the process proceeds to step 63 and the search over flag is turned on. After this, step 56, 57, 58 are performed to print the final page, and the print signal is stepped.
It is turned off at 61, and the process proceeds to step 60 to turn off the multi-print signal. Thus, the multi-print is finished and the process returns.

EFFECTS OF THE INVENTION As described above, according to the reader printer of the present invention, when a plurality of images printed on a microfilm are continuously copied, a frame image is a horizontally long image and When copying on a vertically long sheet of paper, the image is rotated by 90 ° only once before copying the first page, and the image rotating means is fixed during the period until the last page is copied. Unlike the conventional means for rotating the image at the time of printing, there is no accumulation of return error. Therefore, even when printing over a large number of pages, there is an effect that the copied image does not tilt and can always be copied in the normal posture.
