Abstract

PURPOSE:To perform information retrieval and copying operation excellently by fixing a lighting area in reader mode wherein retrieval marks of frames of a film are detected and varying a lighting area according to the power of a projection lens in print mode wherein film images are recorded. CONSTITUTION:Light from an exposure lamp 22 is controlled by a condenser lens 36 to illuminate the film F. An image of the film F is enlarged by the projection lens 39 and projected on a screen 1 in reader mode or recorded on recording paper P on a copying mechanism 68 in print mode. In the reader mode, the film F is moved in its width direction and a sensor detects retrieval marks provided to sides of frames of the film F to decide whether or not there are plural frames. At this time, the area wherein the film F is lighted is fixed to prevent a retrieval mark from exiting from the lighting area. In the print mode, on the other hand, the lighting area is varied according to the power of the projection lens 39 to optimize a copy. Thus, the retrieval marks are detected correctly to record an excellent image.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reader printer that can search for desired information by searching for search marks provided on the sides of each frame of a film.

1' Load and its mountain Reader printers equipped with reading reader mode and print mode conventionally use a film with search marks provided on the side of each frame of the film, and the search marks are detected optically and searched. By counting, the desired frame in the film is automatically searched.

By the way, typical films used in the above-mentioned reader printer are 3 shown in Fig. 18 (a) to (c).
There are different types.

As shown in FIG. 18(A), the first film has one frame FF formed in the width direction of the film F, and one image is formed on this one frame FF. is imprinted thereon, and a search mark M is provided on one side of each frame FF. This type of film is commonly referred to as simplex film.

As shown in FIG. 18(B), the second film is divided into two columns along the longitudinal direction of the film F, and search marks M are formed on both sides of the film F. It is something that This tie film is usually called a duo film, and among the two divided columns, one column is called A channel CA and the other column is called B channel C8. In this duo film, after consecutive images are imprinted on each frame FFA of the A channel cA, the film F is reversed and each frame FF of the B channel C3 is imprinted.

By imprinting another continuous image on the image, it is possible to search for a plurality of consecutive images that are connected to each other.

As shown in FIG. 18(C), the third film is divided into two columns along the longitudinal direction of the film F, and a search mark M is formed on one side of the film F. It was formed. This type of film is usually
It is called a duplex film, and like the above-mentioned duo film, it has an A channel CA and a B channel Cyr. This duplex film is a FF film in which multiple consecutive images are connected to each other.

FFm, FFA, FFg... are printed in this order.

When the film F is irradiated with a light source such as an exposure lamp, an illuminated area is formed as shown in FIG. 19, and the illuminated area is projected onto the screen as a projected image.

In this case, in the case of a simplex film, there is only one frame FFL in the width direction of the film F, and the center C of the film F (see Figure 18 (a)) coincides with the center on the screen, so no problem occurs. , in the case of duo film or duplex film, two pieces FF, , F in the width direction.
F, so there are two image centers (Figure 18 (b)).

(See (c)), and the following problems arise. That is, in the case of a duplex film, for example, it is normally projected onto a screen with the illumination area shown in FIG.
If it is desired to enlarge and project the image imprinted on the frame, there is a problem in that it is necessary to move the film F in the width direction so that the center of the image of the frame FFI coincides with the center of the screen to enlarge and project the image.

On the other hand, when the illumination area is enlarged as described above, there is a drawback that the overall illuminance decreases, so when copying with the illumination area expanded for reader search in print mode, the illuminance decreases as described above. As a result, there was a problem in that the quality of the copied image deteriorated.

An object of the present invention is to solve these conventional problems and provide an extremely useful reader printer that does not cause any problems in information retrieval and copying.

In order to achieve the above object of solving the p1 problem, the reader printer of the present invention has the following features:
a film feeding mechanism that longitudinally transports a film on which a search mark is formed on the side of a frame; a determining means that determines whether a plurality of frames exist in the width direction of the film;
a projection optical system having a projection lens and projecting the image recorded on the film; a copying mechanism for copying the projected image onto recording paper; an identification means for identifying the magnification of the projection lens; and illumination for the film. control means for changing the area, the control means fixing the illumination area to an area where the search mark can be detected without depending on the magnification of the projection lens when searching for information in the reader mode; The gist of this invention is to control the illumination area to change as appropriate depending on the magnification of the projection lens.

It is known from experience that even when a film is enlarged and projected onto a screen, the position of the search mark remains approximately constant in a predetermined area, regardless of the type of film or the magnification of the film. .

Therefore, according to the above configuration, when information is searched in the reader mode, the predetermined area (area where the search mark can be detected) is included in the illumination area regardless of the magnification of the projection lens, so that no search mark is detected. It does not interfere with detection.

In addition, in the print mode, the illumination area is controlled to change appropriately according to the magnification of the projection lens, so it is possible to make optimal settings for copying, and it is possible to obtain a reader printer that does not degrade copy image quality. .

That is, the projection optical system 6 includes the exposure lamp 22 and a condenser lens 36 (which moves in the direction of the arrow G as appropriate to change the illumination area of the film F via a drive means to be described later).

Further, the projection module 37 includes a P lens unit 42 in which a projection lens 39 (hereinafter referred to as "P lens") for enlarging the image on the film P is housed, and a ladder-shaped image rotation prism 40. When the image on the film P is projected sideways or upside down, the image rotating prism 40 is rotated in the direction of arrow E by operating a push button switch (not shown) to transfer the film image onto the screen 1. This is for projecting an erect image.

In such a projection optical system 6, in the reader mode, the image of the film F irradiated via the exposure lamp 22 and the C lens 36 passes through the projection module 37, and is transferred from the first mirror 38a to the second mirror.

That is, the copying mechanism 68 is comprised of a well-known electrophotographic process such as a photosensitive drum 41 and a charging device (not shown), a developing device, a transfer device, a cleaning device, a static eliminating device, etc., and the film image that has passed through the mirror 38e is exposed to light. An electrostatic latent image is formed on the body drum 41, and then an enlarged copy of the film image is formed on the recording paper P through the electrophotographic process described above.

Reference numeral 43 denotes a mounting plate that holds the P lens 39 in an externally fitted manner, and 44 denotes a P lens identification sensor as an example of identification means according to the present invention, which is used to recognize the magnification of the P lens 39.

It is made to be able to run freely on the base 47 by the running element 57. The C lens driving means 48 is configured as described above, and by driving the pulse smoke 49 to perform a predetermined forward or reverse rotation, the C lens 36 held by the holder 53 moves in the direction of arrow G. It is said to be able to move forward and backward at will.

FIG. 9 is a block diagram showing the control system of the reader printer of this embodiment. 58 is a CPU, which includes an arithmetic unit and a ROM.
, RAM, I10 board, etc. Reference numeral 59 indicates a key manual section, in which parameters such as scan mode setting, search mode setting, number of copies, search target frame number, etc. are manually input. The key personnel department 59 is
This figure shows an example of a determining means that can determine whether or not there are multiple frames in the width direction of film F, and by selecting the search mode setting, it is possible to determine whether or not there are multiple frames in the width direction of the film F. It is possible to manually determine whether the film is a duplex film or a simplex film that does not need to be moved in the width direction. Furthermore, since the frame front of the film F is different, the distinction between a simplex film (or duplex film) and a duo film can be automatically made by a control mechanism, which will be described later. The scan mode is used to set whether to prohibit or permit movement of the film F in the width direction. Reference numeral 60 denotes a display section on which the number of copies, frame number, etc. are displayed.

Thus, the light from the exposure lamp 22 that has passed through the film F is received by the light receiving element 33a and/or 33b.
As described above, the photoelectric conversion element of the search mark sensor 32 converts the amount of light transmitted through the film into voltage. Then, the search mark sensor 32 detects the change in voltage caused by the passage of the search mark M, and detects the change in the voltage of the A channel C through the search mark detection unit 61.
The detection signal of the search mark M of the A and B channels C3 is
Input to pU58. Further, when the P lens identification sensor 44 is irradiated with light, a photointerrupter 45a is activated.

45b and 45c are uneven parts 46a and 45b of the mounting plate 43,
46C, recognizes the magnification of the P lens 39, and sends the electric signal to the CPU 5 via the P lens identification section 62.
Make it B. On the other hand, from the key human power section 59 to the CPU 58
Parameters such as scan mode settings are input to the copy process control section 63. from the CPU 58. C lens driving means control section 64, exposure lamp illuminance control section 65. Control signals are transmitted to the film transport mechanism control section 66 and the film movement mechanism control section 67, respectively.

The C lens drive means control section 64 is an example of a control means that is a feature of the present invention, and drives the pulse motor 49 as desired according to information from the CPU 58 instructing the position of the C lens 36. Move the camera to the C lens position. That is, the C lens driving means control section 64
In the reader mode, even when the third motor 27 of the film moving mechanism 8 is driven during a search and the film F is moved in the width direction, the search mark M does not come out of the illumination area regardless of the magnification of the P lens. The position of the C lens is fixedly set, and the position of the C lens is controlled to be set to an arbitrary position by any method such as manually or automatically when not searching. Further, in the print mode, the position of the C lens 36 is controlled according to the magnification of the P lens 39 so as to be optimal for copying.

Further, the exposure lamp control section 65 controls the light amount of the exposure lamp 22 using a well-known phase angle power control method in accordance with information instructing the light amount from the CPU 58. The copying process control section 63 controls the copying mechanism 68 in accordance with commands from the CPU 58 to perform a copying operation. The film feed mechanism control section 66 controls the first motor 10 and the second motor 15 based on information from the CPU 58 instructing the transport speed, transport direction, etc., and moves the film F forward and backward. The film moving mechanism control section 67 includes:
The third motor 27 (see FIG. 3) is driven in accordance with information indicating the film projection position from the CPO 5B. Further, display commands such as the number of copies are transmitted from the CPU 58 to the display section 60, and a predetermined display is performed.

Next, the control procedure of this embodiment is shown in FIGS. 1 and 10 to 16.
A detailed explanation will be given based on the flowchart shown in the figure. Note that the flags used in these flowcharts are defined as shown in Table 1.

[Margin below]

Figure 1 is a flowchart showing the overall control procedure of this embodiment.

Steps (Sl) to (S4) show the initial setting state. In other words, by setting (ENB) to "0", the scan prohibition mode is set and Sl), (BC
By setting NT) to "0", the counter that counts the number of B channels is set to "0", and by setting (DUO) to "0", the mode is set to non-duo film (S2), Next, set (MODE) to "0" to enter the simplex or duo search mode (S3), and manually enter the initial values of the number of frames for the A channel and B channel when the power is turned on (S4).
, load the film and output the frame (35)
, L, and then a specific control operation begins.

First, determine whether or not (ENB)"O, that is, whether there is a possibility of the film moving in the width direction. S6), (ENB
)-0, proceed to route A; if (ENB)=1, proceed to route B. When proceeding to route A, first execute the subroutine for C lens processing 1 (S7), then execute the subroutine for exposure lamp processing 1 (S8),
Thereafter, it is determined whether there is a print request (S9).

This route A is controlled so that the C lens 36 is optimized for copying by C lens processing 1 (C lens driving means control section 64) and exposure lamp processing 1 (exposure lamp control section 65).
The position of the exposure lamp 22 and the illuminance of the exposure lamp 22 are set. Specifically, as shown in FIG. 10, the C lens processing 1 reads the magnification of the P lens 39 attached to the projection optical system 6 via the P lens identification sensor 44 (S71);
The electrical signal is input to the CPU 58. Then the CPU
The C lens driving means is operated appropriately according to the information from 58, and the C lens 36 is moved to the optimum position for copying according to the magnification of the P lens 39 (372), and the process returns (373). In other words, even if the copy size is the same eAd size, the copy area of the film will be different if the magnification of the P lens is different, but in this example, if the magnification of the P lens is large, the position of the C lens is set in a direction that narrows down the magnification of the P lens. The position of the C lens is set so that the illuminance of the copying area of the film is uniform.

In addition, as shown in FIG. 11, the exposure lamp processing 1 is as follows:
The magnification of the P lens 39 is read (S82) in the same manner as the step (S71) of C lens processing 1, and then the light amount is set by the exposure lamp control section 65 (383).

That is, the position of the C lens differs depending on the magnification of the attached P lens, and therefore the illuminance of the copy area also changes.

On the other hand, if (ENB)=1 in step (S6), the flow of route B is proceeded. In this case, it is the scan permission mode, that is, the mode in which the film can be moved in the width direction, and the C lens processing 2 subroutine is executed (5IO).
Next, execute the exposure lamp processing 2Φ subroutine.
l), and then determines whether there is a print request (S
9).

This rule)B is adjusted so that it is optimal for searching the search mark M by C lens processing 2 and exposure lamp processing 2.
The position of the lens 36 and the illuminance of the exposure lamp 22 are set. Specifically, in the above C lens processing 2, C
By driving the lens driving means 48, as shown in FIG.
Move and set the C lens to the optimal position for detecting the search mark M so as not to depend on the magnification of the attached P lens (S
101). In other words, normally, the larger the magnification of the P lens, the narrower the illumination area of the film, and if the film is moved in the width direction, there is a risk that the search mark M will go outside the illumination area, but even if the film is moved in the width direction, Search mark M when searching
The position of the C lens 36 is set regardless of the magnification of the P lens so that the search mark M can be detected so that the search mark M does not deviate from the illumination area. In other words, as mentioned in the section on effects, the position of the search mark during league search can be set to a substantially constant position regardless of the magnification of the P lens, and therefore, when searching, the position of the C lens can be set to the same position as the magnification of the P lens. Even if it is fixed regardless, it will not cause any trouble to the search operation. Note that the issue here is the position of the C lens during a search, and the position of the C lens may be set to an arbitrary position when not searching.

The exposure lamp process 2 is as shown in FIG. 13 (S111) in which the exposure lamp control section 65 sets the optimum illumination for film retrieval.In other words, when moving the film F in the width direction, , the above C lens processing 2 (
SIO), the illumination area is expanded to include the movement range regardless of the magnification of the P lens 42, but expanding the illumination area usually reduces the illuminance on the film surface. Therefore, in this exposure lamp processing 2 (Sll), the P lens 39
The illuminance of the illuminated area is improved regardless of the magnification of the area, so that no trouble occurs in the search. Specifically, the illuminance of the exposure lamp 22 is adjusted by appropriately adjusting the voltage of the exposure lamp 22.

After the C lens 36 and the exposure lamp 22 are set optimally for copying processing or search mark M detection in this way, predetermined copying processing, search processing, etc. are performed. Next, these control procedures will be explained in detail.

Print processing, search processing, scan mode change processing,
If none of the search mode changing processes is requested, the process returns to step (S6) through the flow of (S9)→(S12)→(313)→(514).

When there is a request to change the search mode, for example, to change the simplex/duo search mode to the duplex search mode, the process proceeds to route 1 from step (S14). That is, in this case, manually set the duplex search mode (515) and then check whether it is in duplex mode (31).
6) If it is detected that the film is a duplex film, it sets (MODE) to "1" (517) and returns to step (S6). If you want to search for a film other than a duplex film, press the key S15) on the film mode, confirm that it is not a duplex film (516), set (MODE) to "0" (318), and step Return to (S6). This route 1
shows an example of a determining means for determining whether or not a plurality of frames exist in the width direction of the film F.

If there is a request to change the scan mode, (S9)→(
Proceed as S12) → (S13), and then proceed to this step (S1
Proceed to route 2 flow from 3). That is, for example, if you want to change the scan prohibition mode to the scan permission mode, manually enter the scan permission mode (SL-9).
. Next, check whether it is in scan permission mode52.
0), set (ENB) = 1 in scan permission mode (521), and (ENB) in scan prohibition mode.
)=0 (522) and return to step (S6).

This scan mode changing process is performed by the film moving mechanism control section 67.

If there is a request for search processing, the flow of route 3 is proceeded from step (S12). That is, when there is a search request, first enter the search target frame number (TN) manually (523), then enter the search process subroutine (S24) and the film scan process subroutine (S24), which will be described later.
After executing step 325) and projecting a predetermined image on the screen, the process returns to step (S6). This search request processing is processed by the film feeding mechanism control section 66 and film movement mechanism control section 67.

If there is a print request, the process proceeds to route 4 from step (S9). In other words, when there is a print request, first manually enter the desired number of copies using the 326 key.
), the C lens processing 1 subroutine is executed in the same manner as the flow shown in FIG. 10, and the position of the C lens is set to be optimal for copying (327). This C lens processing l is always executed when printing is performed in any case. Next, a copy processing subroutine is executed (328), and the process returns to step (S6).

Note that after C lens processing 1 (S27), it is necessary to perform exposure lamp processing 1 similar to step (S8), but in this embodiment, this exposure lamp processing 1 is included in copying processing (328). Note that this printing process is performed by the copying process control section 63.

Therefore, in the above search process, the piece number of the A channel or the piece number of the B
This is done by matching the frame number of the channel with the search target frame number. FIG. 14 is a flowchart showing the control procedure for search processing. First, when the search processing subroutine is called (S24), it is checked whether the frame number of the A channel is the frame number for the purpose of search (3201). And if the piece number of A channel is the same as the piece number for search purpose, A
Set the channel as the search end channel (3202), stop the first and second motors 10 and 15 (see FIG. 3), stop the film (S203), and return (S202).
04). If the A-channel piece number and the retrieval-purpose piece number are different, it is checked whether the B-channel piece number is equal to the retrieval-purpose piece number (S205).

If the piece number of the B channel and the piece number for the search purpose are the same, the B channel is set as the search end channel and 320
6), then proceed through the same flow (S203) to (S204) as described above.

Next, if neither the A channel nor the B channel is the piece number for the search purpose, it is first checked whether the piece number of the A channel is larger than the piece number for the search purpose (S207).
. If the frame number of the A channel is larger than the frame number to be searched ((AN)>(TN)), the frame number to be searched is searched by proceeding through the flow of route 5 and retracting the film. On the other hand, if the frame number of the A channel is smaller than the frame number to be searched for, the search is performed on the B channel side.

That is, it is checked whether the B channel frame number is smaller than the search target frame number ((BN)<(TN)) (3208). The search mark M is present on the B channel only in the case of Duo film, and as mentioned above, the A channel and B channel are reversed and continuously imprinted on the Duo film, so ((BN)< (TN
)), similarly to ((AN)>(TN)), the frame number to be searched for is retrieved by proceeding through the flow of route 5 and retracting the film. Specifically, this route 5 first issues a film return output (5209), and then checks whether there is a search mark M on the A channel (S
210). If there is a search mark M on the A channel, (
A N) is set to ((AN)-1) and the film is moved back one frame (3211). If there is no search mark M on the A channel at step (S210), it is checked whether there is a search mark M on the B channel (S212).

If there is no search mark M on the B channel, the process returns to step (S201). If there is a search mark M on the B channel, set (BN) to ((BN) + 1) (3213), then set (BCNT) to ((BCNT) -
1> to move the film back one frame (5214) and return to step (S201). Furthermore, step (S209)
The film return output in step 3 is performed by driving the second motor 15 (see FIG. 3).

Also, if the piece number of the A channel is smaller than the piece number for the search purpose ((AN) < (TN)), and the piece number of the B channel is larger than the piece number for the search purpose ((BN)>
(TN)) performs a search by advancing the frame in the film feeding direction. That is, the film feed output is issued (5215), and the following steps are performed according to the illustrated flowchart (3).
216) → (S217) → (S218) → (S 219
)→(S220). Thereafter, the subroutine ``rBCh check to reconfirm that this film is a duo film'' is executed (5221), and the process returns to step S201.

Note that the film feed output in step (S215) is the first
This can be done by driving the motor 10.

This process is repeated until the frame number on the A channel side or the B channel side matches the frame number for the search purpose. That is, (S201)→(S202)→(S203)→(
S 204) or (205) → (3206) → (S2
The search operation is repeated until the flow of 03)→(S334) is passed.

FIG. 15 is a flowchart showing the subroutine of the above rBCh check, which determines whether the film used is a duo film. That is,
When the “rBCh check” subroutine is called,
First, check whether the number of search marks for B channel is 10 or more ((
BCNT)≧10) is checked (S222). If (BCNT)<10, it is determined that it is not a duo film, and the process returns (S224). Also(
When BCNT)≧10, it is determined that it is a duo film, (DUO) is set to “1” (S223), and the process returns (S224).

FIG. 16 shows a subroutine flowchart of the film scanning process (S25) in FIG. 1. When this subroutine is called, it is first checked whether scanning is permitted (S301). If scanning is not permitted, output a scan neutral output on the screen (5302) and return (
S303). In this case, the image is projected so that the center of the screen and the center of the film F coincide. If scanning is permitted, it is checked whether the search mode is simplex/duo search mode (S304).

And if you are in simplex or duo search mode, please check whether it is a duo film or not (3305)
, if it is not a duo film, it is a simplex film, so only one image is imprinted on each frame of film F, and a scan neutral output is generated.
302), and returns (S303). In addition, in the case of duplex search mode and duo search mode, check whether the search end channel is A channel (5306), and if it is A channel, output the scan A channel output (S307), and return (S306). 30
3). In this case, the film image projected on the A channel is projected so that its center coincides with the center of the screen. On the other hand, if the search end channel is not the A channel, that is, if the search end channel is the B channel, the scan B channel output is generated (8308) and returns (S
303). In this case, the film image projected on the B channel is projected so that its center coincides with the center of the screen.

Figures 17(a) to 17(c) show examples of projected images when film F is projected onto the screen 1 of the reader printer configured as described above. Piece FFO width dimension dv
is set to a magnification that is enlarged to be approximately equal to the vertical dimension Dv of the screen 1. Each frame FF of the simplex film is moved on the moving stage 23 of the film carrier section 3 (see FIG. 3) so that the center line Co along the longitudinal direction of the film coincides with the center line Cs of the screen 1. ) is positioned and projected as shown in FIG. 17(a) (scan neutral output).

Furthermore, if a duo film or duplex film is used in this state, as shown in FIG.
, respectively, are projected on the screen 1 vertically side by side.

Therefore, in this reader printer, by changing the magnification of the P lens, it is possible to enlarge and project the A channel or the B channel together with the search mark M onto the screen 1. That is, when using the film F of duo film and duplex film, the entire moving stage 23 of the film carrier section 3 is moved in the width direction of the film F to change the relative position between the film F and the screen 1, and As described above (the C lens is moved and set so that the illumination area of the film F is expanded, as shown in FIG. 17(C)
As shown in FIG.
can be projected on.

In this way, in the reader printer of this embodiment, when information is searched in the reader mode, the illumination area is fixed to an area where the search mark can be detected without depending on the magnification of the projection lens, so that information can be searched easily and quickly. You can search for information. Moreover, in the print mode, the position of the C lens was set to be optimal for copying, so deterioration in image quality was prevented and the intended purpose could be achieved.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and it goes without saying that the design can be changed within the scope of the invention. For example, whether a plurality of frames exist in the width direction can also be determined by writing a bar code or the like on the leading edge of the film F. Also, by providing multiple C lenses, C
It is also preferable to use a lens group, some of which are moved in the direction of the projection optical axis, and controlled continuously. Furthermore, it is also preferable that the P lens for setting the projection magnification be automatically set using a zoom lens or the like. Further, in this embodiment, the film is automatically moved in the width direction, but it may be moved manually.

As detailed above, the reader printer of the present invention fixes the illumination area to an area where the search mark can be detected without depending on the magnification of the projection lens when searching for information in the reader mode. In the print mode, a control means is provided to control the illumination area to change appropriately according to the magnification of the projection lens, so even if the film moves in the width direction, the search mark does not fall out of the illumination area. In addition, when in print mode, a good copy without deterioration in image quality can be obtained, which is advantageous for information retrieval processing.
