DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a film projection apparatus using a film cartridge containing film.

[Technical background and purpose of the invention]

A film projection device has a storage section that stores multiple film cartridges containing microfilm, and a cartridge is selected from the storage section, and the film is automatically fed out from this cartridge to search for a desired image and place it in a predetermined position. Some devices are constructed with a film retrieval section that stops the retrieval section, and the image of the retrieved film is projected onto a screen in a part of the reader or onto copy paper in a part of the printer for use.

Currently, tank-type cartridges are used to store microfilm, but the cartridges that can be used with film projection devices are limited to specific types, and this projection device cannot handle different types of cartridges. Couldn't use it. Therefore, in places where multiple types of cartridges are stored,
A dedicated film projection device must be provided for each type of cartridge, which is a huge economic burden, and the user must use a different projection device each time the type of cartridge to be used changes. It was inconvenient.

The present invention aims to solve the above-mentioned disadvantages, and it is an object of the present invention to make it possible to use a plurality of types of cartridges in a common projection device.

[Technical means for solving the problem] The present invention comprises a first feeding stage for feeding the film in a first cartridge placed in a first position to a projection position, and a first feeding stage placed in a second position. The present invention also provides a film projection apparatus characterized in that it includes a second feeding means for feeding a film in a second cartridge different in type from the first cartridge to the projection position.

〔Example〕

The present invention will be explained below with reference to illustrated embodiments.

Figure 1 shows a film reader printer equipped with the device of the present invention, and the entire device consists of an upper machine box 1 and a lower machine box 2.
and an operation panel 3 for instructing various operations. A screen 4 and a cartridge insertion slot 5 are provided on the front surface of the upper machine box l.

Inside the upper machine box 1, as shown in FIG. 2, there is a built-in cartridge receiving member ll that holds the first cartridge 10 automatically selected from the cartridge storage section in the lower machine box 2 in the first position. , an external cartridge receiving member 13 that holds the second cartridge 12 manually inserted from the cartridge insertion port 5 in the second position, and the first cartridge 1

, an image sensor 17, a take-up reel 18, and the like are arranged. The external cartridge receiving member 13 is installed above the built-in cartridge receiving member 11. Note that the first machine box 1 and the second machine box 2 can be separated, and the first machine box can also be used alone.

The first cartridge 10 and the second cartridge 12 are of different types.

5(A) and 5(B) show the appearance of each cartridge. As shown in FIG. 5(A), the first cartridge 10 has a substantially U-shaped frame IOA and a microfilm F. The reel IOB is rotatably supported by a circular holding part OC formed on the frame IOA. When pulling out the microfilm in the first cartridge, a film feeding roller (described later) is brought into contact with the microfilm F wound on the reel IOH, and when this feeding roller is rotated in the film drawing direction, the rotational force of the feeding roller is 1st
The microfilms in the cartridge 10 are sequentially pulled out from the film inlet/outlet lOD. When the axis of the reel IOB is rotated in the direction of the arrow, the microfilm F is rewound onto the reel IOH. The first cartridge 10 is generally referred to as an E-type cartridge.

As shown in FIG. 5(B), the second cartridge 12 has a rectangular machine box 12A for storing the film, and a film entrance/exit 12B is formed on the side of the machine box 12A. The microfilm in the second cartridge 12 is wound around a reel (not shown), and a leader tape R is connected to the tip of the microfilm, which has a width larger than that of the microfilm and a width larger than the spacing between the flanges of the reel. has been done. When pulling out the microfilm in the second cartridge, a film feeding roller (described later) is brought into contact with the leader tape H wound around the outer periphery of the reel in the cartridge, and this feeding roller is rotated in the film drawing direction. The leader tape and microfilm in the second cartridge 12 are sequentially pulled out from the film entrance/exit port 12B by the rotational force of the feed roller. To rewind the film onto the reel, the axis of the reel can be rotated in the direction of the arrow. , the second cartridge 12 is generally called an M type cartridge.

In FIG. 2, the illumination unit 15 is composed of a lamp 20, a condenser lens 21, and a mirror 22.
The light is transmitted through a condenser lens 21 and a mirror 22 to a pair of glass plates G1. It is projected onto the microfilm F placed between G2. The light transmitted through the microfilm passes through the imaging lens 16, is reflected by mirrors 23 and 24, and is projected onto the image sensor 7.

The image sensor 7 consists of a light receiving element array such as COD, and converts the image on the microfilm into an electrical signal. After the image signal output from the image sensor is processed by a signal processing circuit, it is sent to a known printer such as a laser beam printer, and a copy image is obtained by the printer. When using the above device as a reader, the imaging lens 16
The light passing through is projected onto a screen 4 via an optical system (not shown), and the image of the microfilm is observed on the screen. Incidentally, instead of the image sensor 7, a known photosensitive body may be placed at this position to perform copying (A/).

Figure 3 shows the microfilm feeding path.
The microfilm in the cartridge 10 is in the first passage 3.
1, passes through the second passage 32, and then passes through the glass plates Gl and G2.
The microfilm in the second cartridge 12 passes through the third passage 33, the second passage 32, passes between the glass plates G1 and 02, and is fed to the take-up reel 18. 18. The first passage 31 and the third passage 33 meet at the second passage 32, and the cartridge 10
- The microfilms in 12 are fed through a common second path 32.

A film guide plate is provided along each path 30 to 33,
Each film is guided along a predetermined path by a film guide plate. 35 and 36 are film feed rollers, 3
7 is a film guide roller, and 38 is a mark detector.

The film feed roller 35 is connected to a motor, and is moved by a rotary lens (not shown) between a position in which it contacts the microfilm in the first cartridge 10 placed in the first position and a position away from the film. Further, the film feed roller 36 is connected to a motor, and is moved by a rotary lenoid (not shown) to a position where it contacts the leader tape in the second cartridge 12 placed at the second position and a position where it is separated from the leader tape. .

When using the first cartridge 10.

In response to the search command, the roller 35 rotates counterclockwise and moves to a position where it contacts the microfilm F in the first cartridge 10. When the roller 35 contacts the microfilm, the microfilm is removed from the first cartridge 10. The leading end is pulled out, and this film F passes through the first passage 31.
, which is fed to the take-up reel 18 through the second passage 32.
The take-up reel 18 is driven by a motor at the time of a search command,
When the leading edge of the microfilm is fed, it automatically winds up the leading edge of the film. When the leading edge of the microfilm is wound around the take-up reel 18, the rotation of the roller 35 is stopped and the roller 35 is moved to a position away from the film. Thereafter, the film is pulled out from the first cartridge by rotation of the take-up reel and wound onto the take-up reel. When rewinding the microfilm into the first cartridge 10, the roll IOB within the first cartridge 10 is rotationally driven in the winding direction by a motor (not shown).

When using the second cartridge 12, the roller 36 rotates in response to a search command and moves to a position where it contacts the leader tape in the cartridge 12. When the roller 36 contacts the leader tape, the leading end of the leader tape is removed from the cartridge 12. Then, the leading end of the microfilm is pulled out, and the leader tape and film are fed to the take-up reel 18 through the third passage 33 and the second passage 32, and taken up on the take-up reel 18 in the same manner as described above. It will be done. When the leading end of the leader tape is wound around the take-up reel 18, the rotation of the roller 36 is stopped and the roller 36 is moved to a position away from the film. Thereafter, the film is pulled out from the second cartridge by rotation of the take-up reel and wound onto the take-up reel. Microfilm cartridge 1
When rewinding into the cartridge 12, the shaft of the reel within the cartridge 12 is rotationally driven in the winding direction by a motor (not shown).

The mark detector 38 is for detecting the counting mark attached to the side of each frame of the microfilm, and is composed of a photoelectric conversion element, and is driven to the opposite side of the illumination section 15 with the film sandwiched therebetween. The mark on the microfilm has a density similar to that of its surroundings, and when the microfilm is fed, the light incident on the mark detector 38 is interrupted by the mark, so that the mark detector 38 outputs a mark detection signal. The mark detection signal that is output when the mark detector detects a mark is counted by the counting section, and the counted value of the counting section is compared with the address number of the desired frame, and when the two match, the film is stopped. A desired top can be searched, and the searched top is placed in the projection optical path.

The details of this retrieval device are described in Japanese Patent Publication No. 15691/1983, and will therefore be omitted.

Inside the lower machine box 2, as shown in FIG.
0 and a cartridge gripping mechanism 51 that selects and takes out one of the first cartridges in the storage section 50 and transports it to a first position.

The cartridge storage section 50 includes drums 50A to 50 that store a large number of first cartridges 10 in radial alignment.
F are stacked at predetermined intervals, and each drum 50A to 5
0F rotates around a central axis 52. Each drum is of identical construction, with radial compartments for separately housing each cartridge.

The cartridge gripping and transporting mechanism 51 is connected to the cartridge storage section 5.
an elevating member 56 that moves up and down in the direction of arrow A along a pole 55 vertically installed in the vicinity of 0;
It is composed of a moving member 57 that moves backward, and a hand 58 that is disposed at the tip of the moving member 57 and grips the Ml cartridge. The elevating member 56 can move up and down from the top to the bottom of the pole 55. The moving member 57 reciprocates between a forward end position where the first cartridge in the storage section 50 can be gripped by the hand 58 and a backward end position where the first cartridge gripped by the hand is positioned outside the storage section 50. and rotates in the direction of arrow C from a horizontal state to a vertical state. hand 58
has a claw structure capable of gripping the first cartridge stored in the storage portion 50, and is capable of gripping and releasing the first cartridge.

In the above configuration, in the initial state, the movable member 57 is in the horizontal position and the backward end position shown in FIG.
is at the bottom or middle home position of the pole 55.

Now, if you input the search number of the desired first cartridge and the search number of the desired piece in this cartridge into the keyboard of the operation panel 3 and command to start the search, the elevating member 56 will accommodate the desired cartridge of ff1l. The drum rotates as it moves up and down to the desired drum position. When the compartment housing the desired first cartridge reaches a position where it can be gripped by the hand 58, the rotation of the drum is stopped, and the moving member 57 is advanced to the zero position where the desired cartridge and the hand 58 face each other. Advance the hand 58 to the end position.
When the hand contacts the desired cartridge 10, the hand is operated to grasp the cartridge 10. After gripping the cartridge, the contact member 57 is moved backward, and when the moving member 57 reaches the end position of the backward movement, the elevating member 56 is raised and the moving member 57 is rotated to the upright position. The movable member 57 is in the upright state before the elevating member 56 reaches the top of the pole 55, and then the cartridge 10 is carried to the built-in cartridge receiving member 11 by the upward movement of the elevating member 56 and placed in the first position. . The cartridge IO is held at the first position by the moving member 57 and the elevating member 56.

Next, the feed roller 35 rotates and comes into contact with the film in the first cartridge 10 placed at the first position to feed the microfilm out of the cartridge 10, and a desired frame in the microfilm is searched. After the microfilm of the desired cartridge IO is used in the reader part or the printer part, when rewinding is commanded, the microfilm is rewound to the first cartridge IO, and after the rewinding is completed, the elevating member 56 is lowered, The moving member 57 rotates to a horizontal state. When the elevating member 56 descends to the drum position where the cartridge is returned and the movable member 57 reaches the horizontal state shown in FIG. 4, the used cartridge can be returned to its original compartment by moving the movable member 57 forward. . After this return, if an instruction is given to search for the first cartridge to be used next, the above-described operations are repeated.

On the other hand, when using a second cartridge of a different type from the first cartridge after using the first cartridge, while searching for the desired @1 cartridge or removing the microfilm in the first cartridge. While using the second cartridge 12, insert the second cartridge 12 through the cartridge insertion opening 5, hold it in the external cartridge receiving member 13, place the second cartridge 12 in the second position, and insert the second cartridge 12 into the second cartridge 12. Enter the search number of the desired piece into the keyboard of the operation panel 3 and command the start of the search.
After using the retrieved microfilm of the first cartridge IO, when all of the microfilm is rewound into the IT cartridge IO, the feed roller 36 rotates while the second cartridge 12 is placed in the second position. The microfilm is sent out of the second cartridge 12 by contacting the leader tape of the microfilm, and a desired frame in the microfilm in the second cartridge is searched.

Therefore, while the used first cartridge is being returned, the second
different types of cartridges can be used with a common imaging device,
Moreover, part of the reader and part of the printer of the apparatus can be used efficiently, and the usable capacity of the cartridge can be increased without adding an additional storage section 50.

Next, while using the second cartridge, when a command is given to the keyboard to search for the desired first cartridge to be used next, the above-mentioned operation is performed and the desired first cartridge is transported to the built-in cartridge receiving member 11. A first cartridge to be used next can be kept waiting at the first position. After using the microfilm in the second cartridge 12, when the entire microfilm is rewound into the second cartridge 12, the first
A search operation for the microfilm in the first cartridge waiting at the position is started. Therefore, by alternately using the first cartridge and the second cartridge, the device can be used effectively.

Although two types of cartridges are used in the above-described embodiment, it is also possible to use three or more types of cartridges. In this case, each type of cartridge is held in a different position, and the cartridges held in each position are selectively fed into a common path.

FIG. 6 shows a third cartridge different in type from the cartridge of the above embodiment, and shows the third cartridge 7.
0 has a rectangular machine box 70A that stores microfilm, and the upper corner of the 11 box 70A has a film entry/exit lower 0B.
is formed. The microfilm in the third cartridge 70 is wound around a shaft 70G. A protrusion 700 is provided at the tip of the microfilm F. Protrusion 70
D has a shape that prevents it from entering the machine box by engaging with the entrance/exit lower 0B, so that the leading end of the microfilm F always comes out of the machine box.

FIG. 7 shows a mechanism for pulling out the microfilm in the third cartridge 70.
When the camera is installed in a predetermined position and a command is given to start a search, a rotary solenoid (not shown) that rotates the capstan roller 72 in the direction of pulling out the film is energized, and the pinch roller 73 moves in the direction in which it comes into contact with the capstan roller 72. It moves downward around the axis 74. Due to the downward movement of the pinch roller 73, the leading edge of the film exposed to the outside of the cartridge from the film loading/unloading lower 0B of the cartridge 70 is caught between the capstan roller 72 and the pinch roller 73, and the rotating force of the pinch roller 72 The shaft 70C, through which the film F is sequentially drawn out of the cartridge 70, rotates following the film. The drawn film is sent to a fourth passage 75 composed of a guide plate. The fourth passage 75 is connected to the first passage 32 described above. The third cartridge is commonly referred to as a type cartridge.

Note that the mechanism for selecting a cartridge stored in the storage portion is not limited to the embodiment, and any known cartridge selection mechanism may be used.

〔effect〕

As described above, according to the present invention, a plurality of cartridges of different types can be used with just one projection device, which is very economical and can improve work efficiency. Further, the projection device can be used efficiently and information about the film in each cartridge can be found in a short time. Furthermore, by providing a cartridge accommodating portion and a cartridge gripping mechanism, the usable capacity of the cartridge can be easily increased without increasing the capacity of the built-in cartridge.
