[0002]

2. Description of the Related Art A roll as an information retrieval device equipped in a microfilm reader, a reader printer or the like (hereinafter referred to as a device body such as a reader) is a roll as an installed long-sized information recording medium. Forward transport of microfilm between the take-up and rewind parts via the projection position (film illumination part)
Address information of a desired image frame portion (image information portion, micro image portion) to be searched, which is provided with a film conveying means for performing reverse conveyance, and which is input to the control portion in advance by the input means,
Mark detection information input to the control unit from the mark detection means for detecting the search mark previously given to the individual image frame portions sequentially printed along the length of the film in the forward or reverse feeding process of the film. The film transport means is automatically driven / stopped so that the desired image frame portion is searched for at the projection position and stopped at the projection position by the comparison calculation with (automatic search operation mode). It is also possible to have a dial for manually controlling the film transporting means, and by this dial operation, the film can be transported in the forward or reverse direction to locate the desired image frame portion at the projection position (manual search operation mode).

The image frame portion searched for at the projection position can be read by being enlarged and image-projected onto the reader screen surface by the projection optical system on the main body of the device such as a reader. In the case of a reader printer, if you want to obtain a magnified print of the image frame, press the print button to activate the print mechanism, and the image frame will be enlarged and projected onto the recording medium to execute printing. It

Roll microfilm has several standards (modes) for imprinting microimages.
10 (a), (b), and (c) of FIG.

(A) is a microfilm in which one micro image is imprinted in the width direction of the film F (a microfilm in which one channel is imprinted in the film width direction). This imprinted film is hereinafter referred to as "simplex film".

[0006] (b) is a microfilm in which two different micro images are imprinted in the width direction of the film F (a microfilm in which two channels are imprinted in the film width direction). This imprinted film is hereinafter referred to as "duo film".

(C) is a microfilm in which the front and back of the same image are imprinted in the width direction of the film F (a microfilm in which two channels are imprinted in the film width direction). This imprinted film is hereinafter referred to as "duplex film".

In each of the microfilms (a) to (c) described above, a is an image frame portion which is sequentially printed along the length of the film, and m is given corresponding to these image frame portions. It is a search mark. In the automatic search operation mode, the search mark m is automatically detected by the mark detecting means during the forward or reverse feeding of the film so that the desired image frame portion is searched for at the projection position and is stopped. Drive / stop control is performed.

Stop position setting in the film longitudinal direction (film feed direction) with respect to the projection position of the image frame portion
The adjustment can be performed by controlling the film transport means. That is, with respect to the film feeding direction, the stop position with respect to the projection position of the image frame portion can be set so as to be projected on the reader screen of the main body of the device such as a reader and stored in a preset print frame.

The channel used is switched to the projection position of a microfilm such as the duo film of (b) or the duplex film of (c) in which two channels are imprinted in the film width direction. Alternatively, a carrier upper unit including a film conveying means) can be moved in the film width direction with respect to the support portion, and this film carrier is moved in the film width direction.

Conventionally, the device for moving the film carrier in the film width direction is constituted by a manual operation tool such as a knob or a lever and an interlocking mechanism for mechanically interlocking the manual operation tool and the film carrier. To switch the channel of film or duplex film, the user operates the manual operation tool to move the film carrier in the film width direction with respect to the main body of the reader while watching the microfilm image projected on the reader screen. , By changing the relative position of the film and the screen.

However, in the case of adopting the above-mentioned structure, when projecting a micro image having a channel different from that of the currently projected micro image on the screen, the film is operated by operating the manual operation tool one by one. It is necessary to move the carrier, and moreover, it is necessary to carefully operate the manual operation tool in order to perfectly display the necessary micro image on the screen according to the relative position of the film and the screen, and the micro image as a whole. It was impossible to efficiently perform the projection operation of.

Further, even when the search is performed under the control of an external device, if the channel is changed, the automatic execution is temporarily interrupted at that time, and the projection position must be adjusted by the manual operation. Had to operate both the external device and the film carrier as the information retrieval device, or required a plurality of operators.

To solve this problem, it is proposed to automatically move the film carrier in the film width direction at the time when the channel is found after searching for channel switching of duo film (Japanese Patent Publication No.
103376, Japanese Patent Publication No. 7-1366) has already been made.

[0015]

However, even in the case of such an automatic device, when the film cartridge is replaced and a simplex film or the like in which one micro image is imprinted in the film width direction is projected, the projection position is set to the previous value. This may be different from other films (e.g. Duo film), and the user manually moves the film carrier to change the relative position between the film and the screen while looking at the microfilm image projected on the screen. It was

Further, since the image position of each channel on the duo film and the image position on the simplex film are different for each film and for each projection magnification, the channel image position of the duo film is relatively moved, and thus the search is performed. Before I started, I had to reset the image position.

Therefore, in the present invention, like the above-mentioned film carrier, a long information recording medium is conveyed and a desired image frame portion recorded on the recording medium is searched and positioned at a predetermined position. Regarding the information retrieval device having a device moving means for moving the device in the width direction of the recording medium ,. By moving the device in the width direction of the information recording medium, it is possible to perform the alignment of the information recording medium in the width direction with respect to a predetermined position of a required image information portion ,.
To enable efficient projection work of a desired image information portion regardless of the image information imprinting standard of the information recording medium ,. The object is to ensure that the desired image information portion can be displayed on the screen.

The control section 25 performs comprehensive control (eg, troubleshooting) in the processing means 20, and
The control unit 25 also serves as a motor drive control unit for transporting the microfilm F. Further, it also serves as a reference position detecting means for moving the film carrier C in the width direction of the microfilm F according to the processing result of the mark information and a motor drive control means.

The calculation section 24 compares and calculates the image frame number input from the input means 23 with the mark information stored in the storage section 22, and outputs the result to the control section 25.
Reference numeral 27 is a display for displaying the address of the image frame.

(5) Operation of the film feeding section The cartridge 1 is mounted on the upper unit 3 of the film carrier C.
When it is mounted on the mounting portion 2a and the operator inputs a desired image frame number to the input means 23, the motor M1 is driven via the motor control circuit 26 and the solenoid S1 is operated. As a result, the capstan roller 2 becomes the cartridge 1.
The microfilm F is pulled out from the cartridge 1 by coming into contact with the lead tape portion of the microfilm F coming out of the film guide roller 6
-> Projection glass part A-> Film guide roller 7-> The film is fed through a film feeding passage extending to a take-up reel 8. When the leading end of the lead tape portion approaches the take-up reel 8, the take-up motor M3 is driven, and the lead tape portion is wound around the take-up reel 8 (auto loading).

Next, the motor M1 and the solenoid S1 are deactivated, but the microfilm F is wound on the take-up reel 8
By the rotation, the cartridge 1 is continuously conveyed forward from the cartridge 1 side to the take-up reel 8 side.

While the microfilm F is being fed, the mark m detected by the mark detecting means 17 is compared with the frame number input in advance after a predetermined time by the arithmetic section 24. If they match, a stop signal is issued from the control section 25. Then, the brake solenoid S3 is actuated to control the winding shaft of the winding reel 8, and similarly S2 also controls the shaft of the motor M2 to prevent the coasting rotation of the delivery spool in the cartridge 1 to The feeding of the film F is stopped, and the film F
Projection glass part A where the desired image frame part of is the projection position
Is searched for and stopped (automatic search operation), and the micro image of the image frame portion is projected onto the screen 30 via the projection lens 16.

Also, in the process of controlling the reverse transport of the microfilm F from the take-up reel 8 side to the cartridge 1 side, the automatic search operation control of the desired image frame portion of the film F is performed.

(6) Movement Control of Film Carrier C When the used microfilm F is a simplex type film as shown in FIG. 10 (a), the movement of the microfilm F in the longitudinal direction is performed in the same order as the photographing order. Be seen. That is, since the microfilm F of the siren plex type has the mark m of each micro image only on one channel side, the number of the mark m of each micro image is counted using the signal from the mark detecting means 17a or 17b. I will go up. Here, FIG.
The difference from the duo-type microfilm F as shown in (b) is that even if the search is not completed, only one channel exists, so the channel can be identified.

Further, in a state where the film carrier C is installed in the reader printer RP, a micro image which is recording information on the micro film F illuminated by the light source lamp 14 is projected on the screen 30. However, if the previously projected micro image is a duo-type micro film F, the projected micro image may run off the screen 30 as shown in FIG. 6A. This is because when the duo-type microfilm F is projected on the screen 30, the microimages of the two channels are projected only partially on the screen 30 as shown in FIG. A micro image of either channel as shown in (b) or (c) is displayed on the screen 3
This is because the film carrier C is moved so as to project 0.

Therefore, the film carrier C (carrier upper unit 32a) is set to the micro by the film carrier moving mechanism B (FIG. 4) so that the duo type micro film F and the non-duo type micro film F can be mixed. Move in the width direction of the film F,
The relative position between the microfilm F and the screen 30 can be changed.

Thus, even when the simplex type microfilm F is used after the duo type microfilm F is used, for example, FIG.
As shown in, the micro image can be projected on the screen 30 without any defects.

Specifically, the motor 37 (see FIG. 7) is used to move the film carrier C by a predetermined distance from the reference position detected by the reference position detecting means 38 so that the designated micro image can be projected on the screen 30. The drive control of 4) is performed. As a result, the micro image on the screen 30 is, for example, as shown in FIG.
It is projected as shown in.

To further explain this control, the processing means 20 (FIG. 5) calculates the drive distance of the motor 37 from the reference position detected by the reference position detecting means 38 described above.
The current position in the width direction of the microfilm F can be stored by performing calculation based on time and the number of pulses. Then, the search for micro images is started,
If the previous film type is a duo type when it is determined as a micro film F other than the duo type, the motor 37 is moved in a predetermined direction by a predetermined distance from the reference position to move the film carrier C to the micro film. It is designed to be moved in the width direction of F.

The reference position detecting means 38 is arranged so that the center position in the width direction of the microfilm F can be known, and must be passed when the motor 37 is driven to move the film carrier C. , You can move in absolute position.

The reference position detecting means 38 may be located at the end of the microfilm F in the width direction as long as it is arranged so that the position of the microfilm F in the width direction can be known. However, when the film carrier C is moved, it must be controlled so as to pass the reference position.

In this example, the film carrier C is moved when the search is started and the film type is known. However, the film carrier C may be moved when the search is completed. That is, even when the duo-type microfilm F and the non-duo-type microfilm F are used in a mixed manner, the frame number is used to input the input means 2.
The micro image input from 3 can be projected on the screen without any trouble.

However, the moving distance from the reference position is different from the reference position because the position of the microfilm F photographed on the microfilm F in the width direction differs depending on the photographing model, photographing form, photographing reduction ratio and the like. The distance can be input from the input means 23 and stored.

The method of storing the movement amount from the reference position is
Conventionally, if the counting method of the mark m, the type of the mark m, and the like are not separately stored according to the specifications of the film F, it is not possible to correspond to various film body types of the film F. However, although it exists in the film carrier C, it may be configured such that it is added to the setting item of the search mode so that it is not necessary to re-input the moving distance only by selecting the search mode.

As described above, in this example,
An image retrieval apparatus comprising a film carrier for holding a microfilm F on which a microimage is imprinted, and a film carrier width direction moving means for moving the film carrier in the width direction of the microfilm,
By moving the film carrier in the width direction of the microfilm when the position of movement of the film in the width direction is determined, the width direction alignment of the microfilm for projecting a micro image on the screen can be performed with less trouble.

Further, it has a reference position for moving the film carrier, and has means for inputting a moving amount of the film carrier from the reference position in the width direction of the microfilm and a storage device for storing the moving amount. Yes, Microfilm F with different printing standard
Even when using, the amount of movement from the reference position is once set by the input means, and thereafter, the film carrier is moved so that any micro image is projected to a predetermined position only by performing a search. Therefore, it is possible to realize with a simple structure of means for moving the film in the width direction and the reference sensor, and it is possible to efficiently perform the projection operation of the micro image regardless of the imprinting standard of the micro film F.

<Embodiment 2> (FIGS. 8 and 9) As described in Embodiment 1 above, FIG.
In order to project the micro image of the simplex type micro film F as shown in FIG.
The film carrier C could be moved to the position of the simplex type microfilm F by the shift mechanism B.

However, when the prism lens 40 is arranged on the projection optical path as the image rotating means as shown in FIG. 8, for example, the tilted projection micro image is corrected as shown in FIG. 9A. Therefore, when the prism lens 40 is rotated, the image projection position moves like Y1.

Therefore, in this example, a correction means for correcting the relative position between the film and the screen by changing the shift movement amount of the film carrier C in the film width direction according to image rotation and projection magnification will be described.

FIG. 8 shows a prism lens 40 for rotating an image.

Is an encoder. When the manual knob 44 is operated in the forward and reverse directions, the rotation of the prism lens 40 or the zoom lens 41 is controlled by an electric mechanism in association with the rotation angle according to the operation rotation angle amount.

That is, when the knob 44 is rotated, this rotation angle amount is read by the encoder 45, and the rotation angle information is transmitted to the processing means 20 which is the control circuit of the apparatus. That is, the processing means 20 converts the number of output pulses of the encoder 45 when the knob 44 is rotated into the rotation angle of the knob 44, and based on the angle information, the prism lens 40,
Alternatively, the rotation angle of the zoom lens 41 is calculated, and the drive signal of the prism lens motor 42 or the zoom lens motor 43 is transmitted to the motor drive control circuit 26, and the prism lens 40 or the zoom lens 41 is set as the operation rotation angle amount of the knob 44. It is rotated by the corresponding angle.

However, at this time, selection of whether to rotate the prism lens 40 or the zoom lens 41 can be performed by a select key or the like (not shown).

When the prism lens 40 is rotated,
The prism lens rotation angle detection means 46 detects angle information and sends it to the processing means 20. When the zoom lens 41 is rotated, the zoom lens rotation angle detection means 47 detects the angle information and sends it to the processing means 20.

FIG. 9A is a diagram showing the movement of an image when the micro image projected on the screen 30 is rotated by the prism lens 40. In the figure,
When the prism lens 40 is rotated, the micro image projected on the screen 30 moves to the position in the direction of the arrow Y1.

FIG. 9B shows the movement of the micro image projected on the screen 30 when the zoom lens 41 is rotated to enlarge the image.
In the figure, when the zoom lens 41 is rotated, the micro image projected on the screen 30 is indicated by an arrow Y.
It will move to the position in the direction of 2.

In the above structure, when the film carrier C moves in the width direction of the microfilm, the rotation angle detected by the prism lens rotation angle detection means 46 and the rotation angle detected by the zoom lens rotation angle detection means 47 are The processing means 20 is configured to perform calculation and correct the movement amount.

That is, in order to enlarge to a desired magnification,
When the zoom lens 41 is rotated, the projection magnification changes as shown in (b) of FIG.
The processing means 20 uses the detected magnification and an image position detection sensor (not shown) to detect whether the image is projected without protruding from the screen.
2 is calculated and the movement amount of the film carrier C is corrected.

Further, in order to correct the tilted image,
When the prism lens 40 is rotated, the projection image is rotated as shown in FIG. 9A and protrudes from the screen 30, so that the processing unit 20 detects the detected angle θ and an image position detection sensor (not shown). The moving amount L1 is calculated based on a detection unit that detects whether the image is projected without protruding from the screen 30. Here, the movement amount L1 is converted from the projection magnification to correct the movement amount of the film carrier C.

In this example, the prism lens 40 and the zoom lens 41 are driven by a motor, but the image rotation angle,
If the projection magnification can be detected, manual driving may be performed.

Since the optical axis shift of the prism lens 40 occurs due to the rotation, the image projection position may shift, but it is calculated from the rotation angle of the prism lens 40 by the optical axis shift detecting means (not shown). The optical axis shift amount of may be detected and added to the correction value.

In the duo-type microfilm F, since the image capturing direction changes depending on the channel and the image orientation may be reversed when projected on the screen 30, the prism lens 40 is rotated. The image may be automatically rotated in the normal direction, and the deviation amount generated at that time may be added to the correction value.

Thus, the rotation angle of the projected image,
By adding the correction value according to the projection magnification to the movement amount, the film carrier can be moved to a predetermined position more accurately, so that a desired image can be surely displayed on the screen 30.
