Next, a second embodiment of the present invention will be described below with reference to FIG. 12, FIG. 13, FIG. 14, and FIG. The document holding mechanism in the scanner device according to the second embodiment is fixed to the scanner device unlike the above-described first embodiment, and detects the type of the loaded film. The operation is switched according to the type of the detected film.

FIGS. 12 and 13 are views showing only the original holding mechanism applied to the scanner device of the second embodiment, and FIG. 12 is an exploded perspective view of the original holding mechanism. FIG. 13 is an enlarged view of a main portion showing only a mask member for determining a screen frame of a film image of the document holding mechanism.

The configuration of the scanner of the second embodiment other than the document holding mechanism is basically the same as that of the scanner of the first embodiment. Therefore, only a portion different from the above-described first embodiment, that is, a document holding mechanism will be described, and other configurations will be described with reference to FIGS.

Here, the cartridge film,
That is, the film width of the roll-shaped film wound around the spool shaft supported in the cartridge is:
It is assumed that a strip film that is narrower than the film width of a strip film that is sandwiched and held by a plate-like case is applied.

As shown in FIG. 12, a document holding mechanism 60 applied to the second embodiment is formed by integrally fixing a front main body 61a and a rear main body 61b with two screws 63a. And a movable body 62 formed by integrally fixing a front movable body 62a and a rear movable body 62b with two screws 63d.

The two rods 61c provided on the upper part of the front body 61a of the main body 61 have one ends fixed to a fixing member in a scanner device (not shown) and the other end movable. The movable body 62 is fitted in a hole 62c provided in the front movable body 62a of the body 62.
The main body 61 is slidable in directions of arrows Y1 and Y2 shown in FIG. The movable body 62 is urged toward the main body 61 by an extensible spring member 63 wound around the two rods 61c.

The rear body 61b and the rear movable body 62b
On one side, a mask member for forming a screen frame 69 corresponding to the film image of the photographed frame recorded on the film (details will be described later; reference numerals 67, 68, etc. shown in FIG. 12).
Is provided.

Further, the rear main body 61b and the rear movable body 62
An insertion port 66 is provided at one end of b. In a normal state, the width of the insertion port 66 is set according to the film width of the cartridge film.

Then, the front body 61a and the front movable body 62
A first roller 66a is rotatably disposed at one end of the first roller 66a and in the film feeding path.
The rotational driving force of the film delivery motor (see FIG. 1) on the scanner device side is transmitted to 6a via a gear train (not shown).

A second roller 66b (not shown in FIG. 12; see FIG. 14) is disposed at a position facing the first roller 66a, and a plate-like case 65 is mounted on the scanner. In this case, the second roller 66b and the first roller 66a pinch the plate-like case 65 to form an automatic feed mechanism for feeding the plate-like case 65.

On the other hand, the front body 61a and the front movable body 62a
The third roller 7 is located at the other end of the
4a is rotatably disposed, and the third roller 74
In a, the rotational driving force of the film winding motor (see FIG. 1) on the scanner device (not shown) side is a gear train (not shown).
Has been communicated through.

A fourth roller 74b (not shown in FIG. 12; see FIG. 14) is disposed at a position facing the third roller 74a, and a plate-like case 65 is mounted on the scanner. Then, the plate-like case 65 is sandwiched between the fourth roller 74b and the third roller 74a,
An automatic feed mechanism for feeding this is formed.

It should be noted that reference numerals 80a and 80b shown in FIG.
Is a rail for guiding the feeding of the cartridge film. Therefore, the rail portion 80a and the rail portion 8
The distance from 0b is set to be substantially the same as the film width of the cartridge film.

Further, one end of the plate-like case 65 applied to the second embodiment has a narrow width corresponding to the width of the insertion slot 66 in a normal state, that is, the width of the film of the cartridge film. A guide portion 65a is formed between the strip film 20 and the portion where the strip film 20 is sandwiched. Thus, when the plate-shaped case 65 is inserted into the insertion opening 66 of the document holding mechanism 60, the movable body 62 is gradually pushed up against the urging force of the spring member 63 to expand the opening of the insertion opening 66. It has a shape that can be used.

That is, when the plate-like case 65 in which the strip film 20 is sandwiched is inserted into the insertion opening 66, the guide portion 65a on the plate-like case 65 side is guided by the guide groove 62d of the movable body 62 of the document holding mechanism 60. Abut on the upper surface of the. In this state, when the plate-like case 65 is further pushed into the insertion opening 66, the movable body 62 is moved in the direction of the arrow Y1 shown in FIG.
Opening is expanded.

A reflecting portion 65b is provided at a predetermined position on the plate-like case 65 corresponding to each photographing frame, and by detecting this, a film image is positioned. That is, the reflecting portion 65
b is the first, which is applied in the first embodiment described above,
This is a detected portion corresponding to the cutout holes 45 and 43 of the second plate-like cases 21 and 21A.

Next, the structure of the mask member will be described below. As shown in FIGS. 12 and 13, the mask member is formed by making an upper mask portion 67 and a lower mask portion 68 each made of an L-shaped thin plate member face each other. The size of the screen frame 69 formed by relatively moving the parts 67 and 68 can be changed.

That is, in the upper mask portion 67, two long holes 67a and 67b are formed so as to be oblique to each side of the screen frame 69, and these two long holes 67a and 67b are formed.
7b is a pin 61b implanted in the rear body 61b.
a and 61bb respectively. In this case, since a flange portion is provided at the head of the pins 61ba, 61bb, the upper mask portion 67 is prevented from easily coming off the rear body 61b by the flange portion. . As a result, the upper mask portion 67 is guided by the pins 61ba and 61bb and moves in the long hole direction.

Further, the upper mask portion 67 is provided with a long hole 67c in a direction crossing the long holes 67a and 67b at a long side thereof, and the rear movable body 62 is provided in the long hole 67c.
The pin 62ba implanted in b is engaged. A flange portion is also provided on the head of the pin 62ba, and the flange portion prevents the upper mask portion 67 from easily coming off the rear movable body 62b.

The lower mask section 68 has two long holes 68a and 68b similarly to the upper mask section 67.
The two long holes 68a, 68b are engaged with pins 61bc, 61bd planted in the rear main body 61b, respectively. In this case, since the flanges are provided on the heads of the pins 61bc and 61bd, the lower mask 68 is not easily detached from the rear main body 61b by the flanges. As a result, the upper mask portion 68 is connected to the pins 61bc, 61b.
The guide member d moves in the long hole direction.

Further, the lower mask portion 68 is provided with a long hole 68c which is inclined in a direction opposite to the long hole 67c, and is implanted in the rear movable body 62b in this long hole 68c. Pin 62bb is engaged. This pin 62b
A flange portion is also provided on the head of b so that the lower mask portion 68 is not easily detached from the rear movable body 62b.

Since the mask member is formed as described above, the rear movable body 62b moves in the direction of arrow Y1 shown in FIG. , In the direction along the long holes 67a, 67b, and to the position shown by the two-dot chain line in FIG.

At the same time, the lower mask portion 68 moves in the direction along the long holes 68a and 68b, and the upper mask portion 67
In the same manner as in FIG. 13, it moves to the position shown by the two-dot chain line.

Therefore, by mounting the plate-like case 65, the size (dimensions in the width direction and the height direction) of the screen frame 69 can be changed.

Adjustment of the moving distance of the mask member, etc.
Each slot (67a, 67b, 67c, 68a, 68b, 6
This can be done by changing the shape of 8c). The adjustment of the mask member that can be performed here includes, for example, performing a non-linear motion with respect to the moving operation of the movable body 62 or moving the screen only in the long side direction or the short side direction. Can be

In the second embodiment,
Although the mask member is configured to be moved by the cam mechanism formed by the pin and the long hole, the invention is not limited thereto, and the mask member may be configured to be moved using, for example, a gear, a roller, or the like. .

Next, the operation of the scanner according to the second embodiment will be described below. First, in the scanner device according to the second embodiment, the strip film 20 is used.
The operation in the case where the plate-like case 65 in which is sandwiched is mounted will be described.

FIG. 14 shows a document holding mechanism when a plate-shaped case is mounted on the scanner device of the second embodiment.
FIG. 13 is a cross-sectional view showing components in the scanner device arranged in the vicinity thereof, and shows a cross section when cut near the insertion port 66 in FIG. 12.

As shown in FIG. 14, first, the plate-like case 65 holding the strip film 20 is inserted through the insertion opening 66 of the document holding mechanism 60. When the distal end of the plate-like case 65 is inserted to a position where the first roller 66a is sandwiched by the first roller 66a and the second roller 66b, the first roller 6
6a is rotated. Here, the first roller 66a is provided with a gear train for transmitting the rotational driving force of the film delivery motor provided on the scanner device side, that is, an idle gear 71, and the like. When the first roller 6 is rotated,
6a starts rotating, and the plate-like case 65 is automatically fed.

The photographing frame position of the strip film 20 held between the plate-like cases 65 is determined by the film position detecting means 7.
5 (for example, a photodetector for detecting the reflection of the projection light) detects the light reflected by the reflector 65b provided at a predetermined position corresponding to the photographing frame of the plate-like case 65, thereby performing position detection. The frame image of the shot frame is displayed on the screen frame 6.
Positioning control is performed so as to stop at a position directly facing 9.

The document holding mechanism 60 is provided with means for preventing the cartridge film from being loaded, that is, a prevention claw 76 connected to the movable body 62 by an L-shaped rod 76a. Reference numeral 76 moves in the same direction as the movable body 62 in conjunction with the movement of the movable body 62 when the plate-shaped case 65 is mounted on the scanner device, and is projected into the cartridge loading section 77. Thus, even if the cartridge 1 is to be loaded into the cartridge loading section 77 while the plate-like case 65 is mounted on the scanner device, the loading of the cartridge 1 is prohibited by the prevention claw 76.

On the other hand, when the plate-like case 65 is to be mounted on the scanner device while the cartridge 1 is loaded in the scanner device, the prevention claw 76 is applied to the cartridge 1 already loaded in the scanner device. Because it abuts,
The movement of the movable body 62 is prevented. Therefore, the opening of the insertion opening 66 of the document holding mechanism 60 does not sufficiently expand, so that the insertion of the plate-like case 65 is prohibited.

The tip of the plate-like case 65 is the fourth case.
When it is inserted to a position where it is sandwiched between the roller 74b and the third roller 74a, the third roller 74a is rotated. Here, the third roller 74a is provided with a gear train for transmitting the rotational driving force of a film winding motor provided on the scanner device side, that is, idle gears 72a and 73a. When the take-up motor is rotated, the third roller 74a starts rotating in conjunction therewith, the plate-like case 65 is automatically fed, and stopped at a predetermined position, and then a film image is scanned.

Next, the operation when the cartridge 1 is loaded in the scanner device of the second embodiment will be described.

FIG. 15 is a cross-sectional view showing a document holding mechanism when a cartridge is loaded in the scanner device according to the second embodiment and components arranged near the document holding mechanism, and is shown in FIG. A cross section cut near the movable body 62 is shown. In this case, substantially the same operation as that of the original holding mechanism 5 corresponding to the cartridge film in the first embodiment is performed.

That is, as shown in FIG. 15, first, after the cartridge 1 is loaded in the cartridge loading section 77, the spool rotating shaft 72 (see FIG. 14) is rotationally driven by a film delivery motor (not shown). By doing
The roll film 4 in the cartridge 1 is sent out into a film feed path formed by rails 80a and 80b (not shown in FIG. 15; see FIG. 12) in the document holding mechanism 60. Further, after the film 4 has passed over the screen frame formed by the mask member, the third roller 81
a, and is guided between the third roller 81a and the film winding shaft 70, and reaches the outer peripheral surface of the film winding shaft 70.

Here, the rotation of the spool rotating shaft 72 by the film delivery motor is stopped, and at the same time, the film winding shaft 70 is driven to rotate by the film winding motor (not shown). Then, the film 4 is moved to the fourth roller 81.
The film is guided by the film b and the film 4 itself onto the outer peripheral surface of the film winding shaft 70, and is reliably wound around the outer peripheral surface of the film winding shaft 70.

In this case, the control of the photographing frame position of the film 4 is performed by detecting the perforation on the film 4 by the transmitted light type film position detecting means 82 provided on the movable body 62 on the original holding mechanism 60 side. It is done by doing.

The original holding mechanism 60 includes a write magnetic head 83 for recording desired magnetic information on the magnetic recording layer of the film 4 and a magnetic type such as a film type previously written on the film. Read magnetic heads 84 for reading information are arranged at positions facing the magnetic recording portion of the film 4 toward the film feed path.

When the plate-shaped case 65 is inserted, the write magnetic head 83 and the read magnetic head 84 are moved in conjunction with the movement of the movable body 62 and the lower mask portion 68 to move the plate-shaped case. 65 is evacuated to a position where it does not interfere.

By the way, in the second embodiment, one film holding mechanism 60 reads a film image of a different film form. Therefore, the case where a cartridge film is mounted on a scanner device and the case where a plate-like case The feeding drive system, the film sending amount for one frame, the means for detecting the film position, and the like are different from those in the case where the sandwiched strip film is mounted. Therefore, it is necessary to change the film feeding control for each type of film to be mounted. Therefore, the form of the mounted film is detected, and the film feed control and the like are changed based on the detection result.

FIG. 16 is a schematic perspective view showing a main part of only a detection switch for detecting a film form applied to the scanner device according to the second embodiment of the present invention.

As shown in FIG. 16, this film form detection switch is connected to a movable body 62 (FIG. 16) of the original holding mechanism 60.
Then not shown. See FIG. ), And a contact piece 78 formed of a conductive material;
Conductive first pattern 79a and conductive second pattern 7
9b.

The contact piece 78 moves integrally with the movable body 62 in conjunction with the movement of the movable body 62.
Of the contact pattern 78, the first pattern 7
9a or the second pattern 79b, so that the film form can be detected.

Note that in the second embodiment,
Although a mechanical switch as described above is applied, the invention is not limited thereto, and a resistance pattern may be provided to detect a resistance value, a capacitance, or the like, or a photoelectric switch may be applied.

As described above, according to the second embodiment, as in the first embodiment, the mechanism itself can be simplified and the size can be further reduced. .

Further, a film type detecting switch for detecting the mounted film type is provided, and different operations (film feeding control, etc.) are performed according to the film type detected by the detecting switch. Unlike the first embodiment, there is no need to prepare a plurality of types of document holding mechanisms corresponding to a plurality of types of films. Therefore, it is possible to omit the work of attaching and detaching the document holding mechanism 60 when reading the film image, to simplify the operation of the scanner device without being conscious of the film form, and to further reduce the manufacturing cost. Can also contribute.

Next, a third embodiment of the present invention will be described below. In the above-described first and second embodiments, the surfaces (positions) on which the film images are arranged when different types of films are mounted on the scanner device are positioned on the optical path by the illumination means of the scanner device. Although it is configured to be arranged on the same plane, this third
In this embodiment, the layout surface of the screen of the film image is arranged at different positions depending on the film form.

FIG. 17 is a block diagram schematically showing a scanner device according to the third embodiment. The configuration of the entire scanner apparatus is the same as that of the first embodiment (FIG. 2).
However, in the third embodiment, the second mirror (13) in the scanner device of the above-described first embodiment is omitted, and the light of the optical system of the scanner device is removed. The shaft 91 is configured to be substantially straight.

The document holding mechanism 92 is fixed to the scanner as in the second embodiment, and uses the same document holding mechanism regardless of the film form. However, the screen position of the shooting frame of the strip film 20 sandwiched between the plate-like cases 93 and the screen position of the shooting frame of the film 4 wound and housed in the cartridge film are determined by the optical system of the scanner device. Are set at different positions on the optical axis 91.

Therefore, in the third embodiment,
The magnetic head 83 for writing and the magnetic head 84 for reading (not shown in FIG. 17; see FIG. 15) can be arranged so as not to interfere with the plate-shaped case 93 when it is mounted. , As in the second embodiment described above,
A mechanism for retracting the heads 83 and 84 can be omitted.

On the other hand, the positions of the screen frames 93b and 94b are arranged at different positions on the optical axis 91 of the optical system of the scanner device, so that the strip film 20 held between the plate-like cases 93 and the film of the cartridge film. In the case where the image reading is performed by alternately mounting the image No. 4 and the image No. 4, since the focus position is greatly different, the film image is displayed on the screen frame 93.
A focusing (focusing operation) operation is required every time the setting is made on b and 94b.

Therefore, in the third embodiment, the type of film (cartridge film, strip film in a plate-like case, etc.) is detected by the film type detection means 95 comprising a film type detection switch 95a and the like. Focus control means 97 based on the detection result
To control the first motor 98a.

That is, by moving the first lens frame 100 for focusing in the optical axis direction, position control is performed so as to offset the amount of change in the position of the screen frames 93b and 94b, and a film of a different form is mounted. In such a case, an in-focus position suitable for the film form is ensured.

Further, in the third embodiment, the optical system 14 is constituted by a so-called zoom lens capable of zooming, so that when the screen size recorded on various films is different, The image is enlarged or reduced with respect to the image sensor 102 so that the area occupied by the film image with respect to the effective screen of the image sensor is maximized.
The zoom magnification is controlled.

More specifically, based on the film type information from the film type detecting means 95, the zoom control means 9
8, the first motor 98a and the second motor 98b are controlled, and the position of the first lens frame 100 and the second lens frame 101 driven by the two motors 98a and 98b is controlled to change the zoom magnification. Is being done.

Next, the operation of the scanner according to the third embodiment will be described below. First, a film is mounted on the document holding mechanism 92 of the scanner device. Then, the type of the film attached to the scanner device is detected by the film type detection switch 95a,
A status signal corresponding to the detected film type is output to the film type detection means 95.

The film type detecting means 95 is loaded with the difference data between the position of the loaded film with respect to the reference film position (here, the film position of the cartridge film) and the long side of the screen of the reference film. The data of the ratio of the film to the long side of the screen are prepared in advance, and the difference data of the film position is calculated based on the detection result by the film type detection switch 95a.
The ratio data on the long side of the screen and the focus control means 97 are transmitted to the zoom control means 98, respectively.

The zoom control means 98 has data of the reference zoom magnification so that the long side of the screen of the reference film is projected with the maximum length within the effective screen range of the image sensor 102. Then, the optimum zoom magnification for the loaded film is set based on the product of the ratio data from the film type detection means 95 and the reference zoom magnification.

Since the position data of the first lens frame 100 and the second lens frame 101 with respect to the zoom magnification is prepared in the zoom control means 98 in advance, the position information of each of the lens frames 100 and 101 with respect to the set zoom magnification is obtained. The position of the first lens frame 100 from the first position detecting means 99a, and the second lens frame 101 by the second position detecting means 99b.
Is compared with the position of the first motor 98a,
By driving the second motor 98b, each lens frame 10
By moving 0 and 101, the long side of the attached film image is projected so as to be the maximum length in the effective screen range of the image sensor 102.

The difference data output from the film type detecting means 95 is input to the focus control means 97 and is converted into a driving amount of the first lens frame 100.

Then, based on the position information of the first lens frame 100 from the first position detecting means 99a, the first motor 9
8a is driven to perform the focusing operation. After that, distance measurement is performed by the AF detection unit, and confirmation of the in-focus state is performed.

As described above, according to the third embodiment, even when the size of the screen of the loaded film is different, the film type is detected and the size of the maximum screen is automatically set. Since the film image is read, troublesome setting operations can be omitted each time the film is changed, and the entire film image of the desired photographing frame can be more efficiently performed without performing unnecessary operations. Can be read with high definition.

When a film having a different form is mounted, the focus position is automatically changed, so that operations such as focus adjustment and the like can be omitted each time the film is changed.

In the third embodiment, the image sensor is an area sensor. However, the present invention is not limited to this. For example, a line sensor may be used to perform a mechanical operation. In this case, the side of the film image corresponding to the longitudinal direction (main scanning direction) of the line sensor is used as a reference, not the long side of the screen of the film image.

Further, the focusing operation has been described with the one having the AF detection means. However, the present invention is not limited to this. For example, a manual focusing operation (manual focus adjustment) may be performed. Even in this case, when the film form is changed, the position of the film surface changes, so if the amount of change is adjusted automatically, only one focusing operation is required, Operation can be unnecessary.
