Abstract

PURPOSE:To optimize the lighting areas of both a reader mode wherein retrieval marks of frames of a film are detected and a print mode wherein film images are recorded by changing the lighting areas for both modes. 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 a projection module 37, reflected by mirrors 38a-38e, and projected on a screen 1 in reader mode or recorded on recording paper P on a copying mechanism 68 in print mode. The film F is moved in its width direction in print mode area sensor detects retrieval marks provided to sides of the 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 expanded to prevent a retrieval mark from exiting from the lighting area. Further, only the image area is lighted in print mode. The retrieval marks are detected corrected in reader mode and an excellent copy is obtained in print mode.

Description

[Detailed description of the invention] Production on the production! 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 film.

In a reader printer equipped with a reader mode and a print mode, conventionally, a film with a search mark provided on the side of each frame of the film is used, and the search mark is optically detected and counted. This automatically searches for a desired frame in the film.

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.

Second. As shown in FIG. 18(b), the film has two rows divided into two along the longitudinal direction of the film F, and search marks M are formed on both sides of the film F. It is. This type of 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 C3. This duo film is produced by imprinting continuous images on each frame FF of the A channel CA, and then
, and each piece FF of the above B channel CI.

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 CI. This duplex film has FFA, which consists of multiple consecutive images that are connected to each other.

FFi, FFa, FFm, . . . are imprinted 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.

By the way, in such a reader printer, it is often desired to enlarge and project a portion of the projected image projected on the screen.

However, in general, the light intensity distribution in the illumination area is high at the center of the film F and low at the periphery, as shown in FIG. Moreover, when enlarging and projecting, there is a drawback that the overall illuminance decreases. Therefore, when the illumination area is expanded, the illuminance of the screen decreases, making the screen dark and difficult to see.

In addition, especially with duo films and duplex films, multiple images are projected in the width direction, so if you move the film in the width direction to enlarge and project one of the images, it is necessary to move the film in the width direction. Since the illuminance near the search mark M corresponding to the periphery of F becomes dark, there is a problem that there is a possibility that the search mark sensor may erroneously detect the search mark M.

Furthermore, if the film is enlarged and projected as described above and then switched to print mode to make a copy, there is a problem in that the image quality of the copied image deteriorates due to uneven illuminance caused by the above-mentioned light amount distribution.

An object of the present invention is to solve these conventional problems and provide a reader printer that can control the illumination area to be optimal in both reader mode and print mode. shall be.

In order to achieve the above object of reading fortune telling, 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 projection optical system that projects an image imprinted on the film; and a copying mechanism that copies the projected image onto recording paper; control means for changing the illumination area of the film, the control means controlling the illumination area of the film to be expanded in the reader mode and to illuminate only the image area in the print mode. The gist is that.

Raw-U According to the above configuration, in the reader mode, the illumination area of the film was controlled to be expanded so that the search mark could be detected, and in the print mode, the illumination area was controlled to be illuminated only to the image area. Therefore, it is possible to obtain a reader printer in which the image quality does not deteriorate even when copying.

, 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 human power section 59 is an example of a determining means that can determine whether or not there are multiple frames in the width direction of the film F, and by selecting the search mode setting, It is possible to manually determine whether the film is a duplex film that needs to be moved in the width direction, a simplex 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.

Move the camera to the C lens position. That is, in the reader mode, the C lens driving means control unit 64 prevents the search mark M from leaving the illumination area even when the third motor 27 of the film moving mechanism 8 is driven and the film F is moved in the width direction. The position of the C lens 36 is controlled in a direction that expands the illumination area of the film F so that it does not come off, and in the print mode, the position of the C lens 36 is
The position of the C lens 36 is controlled to be optimal for copying according to the magnification of the lens 39. - 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 indicating the light amount from the CPU 58. The copying process control section 63 controls the copying mechanism 6B in accordance with commands from the CPU 58 to perform a copying operation. The film feed mechanism control section 66 controls the first motor 1O and the second motor 15 to move the film F forward or backward based on information indicating the conveyance speed, conveyance direction, etc. from the CPO 58. 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 58. 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]

1" - Kazuo FIG. 1 is a flow≠yard diagram showing the entire 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 rOJ, the mode is set to non-duo film (S2). Then set (MOD E) to “0”
By setting it to Simplex, Duo search mode (S3), turn on the power. Next, enter the initial value of the number of pieces for A channel and B channel manually, etc. S4
), load the film and output the frame (35
), then the specific control operation begins.

First, it is determined whether (ENB) = 0, that is, whether there is a possibility of the film moving in the width direction.
)=Q, 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 sets the position of the C lens 36 and the illuminance of the exposure lamp 22 to be optimal for copying by C lens processing 1 (C lens driving means control section 64) and exposure lamp processing 1 (exposure lamp control section 65). It is something to do.

Specifically, in the C lens processing 1, the magnification of the P lens 39 attached to the projection optical system 6 is changed to P, as shown in FIG.
It is read through the lens identification sensor 44 (S71), and the electrical signal is input to the CPU 58. Then the CPU5
8, the C lens driving means is appropriately driven to move the C lens 36 to the optimum position for copying according to the magnification of the P lens 39 (S72), and the process returns (S72).
S73). In other words, even if the copy size is the same A4 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:
Similarly to step (371) of C lens processing 1, the magnification of the P lens 39 is read (382), and then the light amount is set by the exposure lamp control section 65 (S83).
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, in the case of (ENB)-1 in step (S6), the flow of route B is proceeded. In this case, it is scan permission mode, that is, a mode in which the film can be moved in the width direction, and the C lens processing 2 subroutine must be executed (S10).
Then, the subroutine of exposure lamp processing 2 is executed (5ll), and it is then determined whether there is a print request (S9).

This route B is C
The position of the lens 36 and the illuminance of the exposure lamp 22 are set. Specifically, in the C-lens processing 2, the C-lens driving means 48 is driven to find the optimum position for detecting the search mark M, independent of the magnification of the attached P-lens, as shown in FIG. (SIOI), that is, the higher the magnification of the P lens, the narrower the illumination area of the film is, 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. However, in order to prevent the search mark M from leaving the illumination area even if the film moves in the width direction, the position of the C lens 36 is set regardless of the magnification of the P lens, thereby making it possible to detect the search mark M. .

The exposure lamp process 2 is as shown in FIG. 13 (S111) in which the exposure lamp control unit 65 sets the illuminance to the optimum illuminance for searching the film, that is, 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)→(312)→(S13)→(S14).

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 flow of route 1 is proceeded from step (S14). In other words, in this case, the duplex search mode cannot be manually set using the key S15).
Then, it is checked whether or not it is in duplex mode (516), and if it is detected that it is a duplex film, (MODE) is set to "1" (517), and the process returns to step (S6). If you want to search for a film other than a duplex film, manually select the film mode (515), confirm that it is not a duplex film (S16), and set (MODE) to "0" (318). 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)→(
S12)-(S13), and this step (Sl 3
) to proceed to route 2 flow. That is, for example, if it is desired to change the scan prohibition mode to the scan permission mode, the scan permission mode is manually activated (S19). Next, check whether it is in scan permission mode (520).
, set (ENB) = 1 in case of scan permission mode (521), and (ENB) - in case of scan prohibition mode.
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 S25) 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 by pressing the 526 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 (S27). This C lens processing 1 is always executed when printing is performed in any case. Next, a copy processing subroutine is executed (32B), and the process returns to step (S6).

Note that the step after C lens processing 1 (S27) (S8)
It is necessary to perform exposure lamp processing 1 similar to , but in this embodiment, this exposure lamp processing 1 is performed in copy processing (328).
It is included in and processed. 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 (S201). 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 5202), stop the first and second motors 10 and 15 (see Figure 3), stop the film (s 203), and return (S 2).
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 of the search purpose are the same, the B channel is set as the search end channel.
06), then the same as above (S203) → (S 204
).

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). It is only in the case of Duo film that the B channel has the search mark M, and as mentioned above, the Duo film is continuously imprinted with the A channel and B channel reversed, so ( (BN) < (
TN)”), as in ((AN)> (TN)),
The frame number for the purpose of retrieval is retrieved by passing through the flow of route 5 and retracting the film. This route 5 is

), then it is checked whether there is a search mark M in the A channel (S210). If there is a search mark M in the A channel, set (AN) to ((AN)-1) and move the film back one frame (S211), and step (S2
10) If there is no search mark M on the A channel, check 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). Then, if there is a search mark M on the B channel, (BN) is ((BN) + 1
), then set (BCNT) to ((B
CNT)-1) to move the film back one frame 321
4) Return to step (S201). In addition, step (S
The film return output in step 209) 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 for 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 feed direction. That is, the film advance output is issued (5215), and the process is then performed according to the illustrated flowchart (S216) - (S217) → (3218) → (S
219)→(S220), etc. Thereafter, the subroutine ``rBCh check to reconfirm that this film is a duo film'' is executed (5221), and the process returns to step S2Q1. Incidentally, the film feed output in step (S215) can be performed by driving the first 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, (3201) - (S202) → (S203) → (3

The search operation is repeated until the flow of 3)→(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,
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). When (BCNT)<10, it is determined that it is not a duo film and the process returns (3224). Also (BC
NT) ≧10, it is determined that it is a duo film, and (
DUO) is set to rlJ (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, a scan neutral output is generated on the screen (53Q2), and the process returns (3303). 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, check 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.5305
), if it is not a duo film, it is a simplex film, so only one image is imprinted on one frame of film F, and a scan neutral output is generated (5302), and the process 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 "i" (S307), and return (5306). S
303). 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 (3308) and the process returns (S303). In this case, the film image projected on the B channel is projected so that its center coincides with the center of the screen.

FIGS. 17A to 17C show an example of a projected image when the film F is projected onto the screen 1 of the reader printer configured as described above. That is, usually the dimension dv of the simplex film piece FFO in the width direction
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 to the moving table 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, as shown in Figure 17 (
A) is projected as shown in (scan neutral output).

Furthermore, if a Duo film or a Duplex film is used in this state, a pair of pieces FFA and FF existing in the width direction of the film F, 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 Duo Film and Hidew Legs 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 the above-mentioned The C lens is moved and set so that the illumination area of the film F is expanded as shown in FIG.
p a or FFI) can be projected onto the screen 1.

In this way, in the reader printer of this embodiment, the position of the C lens is controlled so that the search mark M does not deviate from the illumination area even if the film F moves in the width direction, so information can be searched easily and quickly. be able to. 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. In the above embodiment, the C lens position in the beam mode is set regardless of the magnification of the P lens, but as long as the conditions for forming an illumination area in which the search mark can be detected are satisfied, The position of the C lens may depend on the magnification of the P lens. Also C
It is also preferable to provide a plurality of lenses to form a C lens group, move some of them in the direction of the projection optical axis, and control them continuously. Further, in this embodiment, the film is automatically moved in the width direction, but it may be moved manually.

As described in detail above, the reader printer of the present invention has a control system that controls to expand the illumination area of the film in the reader mode, and controls to illuminate only the image area in the print mode. Since the means is provided, even if the film moves in the width direction, the search mark can be easily searched without leaving the illumination area, and when in print mode, good copies can be obtained without deterioration of image quality. This has the effect of making it convenient for information retrieval processing.
