As shown in FIG. 2, inside the upper machine box 1, there is an internal cartridge receiving member 11 that holds the internal cartridge 10 automatically selected from the cartridge storage section in the lower machine box 2 in a first position, and an external An external cartridge receiving member 13 that holds the external cartridge 12 manually inserted from the cartridge insertion port 5 in the second position, an illumination unit 15 that illuminates the microfilm sent out from the cartridge IO or 12, and an imaging lens 16. , image sensor 17
A take-up reel 18 and the like are arranged. The external cartridge receiving member 13 is installed above the internal cartridge receiving member 11. Note that the first #1 box 1 and the second machine box 2 can be separated, and the first machine box can be used alone.

The film in the cartridge 10.12 is rolled onto the shaft.

The illumination unit 15 is composed of a lamp 20, a condenser lens 21, and a mirror 22, and the light from the lamp 20 is transmitted through the condenser lens 21 and the mirror 22 to a microfilm F placed between a pair of glass plates Gl and G2. Projected. The light that has passed through the microfilm is passed through the imaging lens 1.
6, is reflected by mirrors 23 and 24, and is projected onto the image sensor 17. The image sensor 17 is composed of a light receiving element array such as a 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 the above device is used as a reader, the light passing through the imaging lens 16 is projected onto the screen 4 via an optical system (not shown), and the image on the microfilm is observed on the screen. Note that instead of the image sensor 17, a known photoreceptor may be placed at this position to perform copying.

FIG. 3 shows the microfilm feeding passage, and the microfilm inside the internal cartridge 10 is transported through the first passage 31.
The microfilm in the external cartridge 12 passes through the second passage 32, then between the glass plates G1 and G2, and is guided to the take-up roll 18.
It passes through the passage 32 and between the glass plates G1 and 02 and is guided to the take-up reel 18. First passage 31 and third passage 33
are joined at the second passage 32, and the cartridge lOΦ1
The two microfilms are fed through a common second path 32. A film guide plate is provided along each of the paths 31 to 33, and each film is guided along a predetermined path by the film guide plate. 35 and 36 are film feed rollers, 37 is a film guide roller, and 38 is a mark detector.

The film feed roller 35 is coupled to a motor M1, and is moved by a first solenoid (not shown) between a position in which it contacts the microfilm in the cartridge 10 placed in the first position and a position away from the film. Further, the film feed roller 36 is coupled to a motor M2, and is moved by a second solenoid (not shown) between a position in which it contacts the microfilm in the cartridge 12 placed at the second position and a position away from the film.

When using the internal cartridge 10, a search command causes the roller 35 to rotate and move to a position where it contacts the microfilm F inside the cartridge 10, and the roller 35 feeds the leading edge of the microfilm out of the cartridge IO. The film F is fed to the take-up reel 18 through the first passage 31 and the second passage 32.The take-up reel 18 is driven by a motor when a search command is issued, and when the leading edge of the microfilm is fed, the film is Automatically winds the tip. 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 internal cartridge by rotation of the take-up reel and wound onto the take-up reel. When rewinding the microfilm into the cartridge 10, a winding shaft within the cartridge 10 is rotated in the winding direction by a motor (not shown).

When using the external cartridge 12, a search command causes the roller 36 to rotate and move to a position where it comes into contact with the microfilm inside the cartridge 12, and the leading edge of the microfilm is fed out from the cartridge 12 by the roller 36, and this film is It is fed to the take-up reel 18 through the third passage 33 and the second passage 32, and is wound onto the take-up reel 18 in the same manner as described above.

Thereafter, the film is pulled out from the external cartridge by rotation of the take-up reel and wound onto the take-up reel. When rewinding the microfilm into the cartridge 12, a winding shaft inside the cartridge lz 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 different density from its surroundings, and when the microfilm is fed, the light incident on the mark detector 38 is continued by the mark, so that the mark detector 38 outputs a mark detection signal. The mark detection signal outputted when the mark detector detects a mark is counted by a counting section, 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 for, and the searched top is placed on the projection optical path. The details of this retrieval device are described in Japanese Patent Publication No. 15691/1983, and will therefore be omitted here.

Inside the lower machine box 2, as shown in FIG. A cartridge gripping and transporting mechanism (hereinafter referred to as CHL) 51 is arranged to transport the cartridge up to the point where the cartridge is held.

In the cartridge storage section 50, drums 50A to 50F that hold the internal cartridges 10 in radial alignment are stacked at predetermined intervals, and each drum 50A to 50F is configured to rotate around a central axis 52. It has become. Each drum is of identical construction with radial compartments for separate storage of each cartridge.

C) The IL 51 has an elevating member 56 that moves up and down in the direction of arrow A along a pole 55 vertically installed near the cartridge storage section 50. A moving member 57 disposed on the elevating member 56 moves forward and backward on the elevating member 56 in the horizontal direction (in the direction of arrow B). A hand 58 disposed at the tip of the moving member 57 is configured to grip the cartridge 10. The elevating member 56 can move up and down from the top to the bottom of the ball 55. The moving member 57 reciprocates between a forward end position where the cartridge in the storage section 50 can be gripped by the hand 58 and a backward end position where the cartridge gripped by the hand is positioned outside the storage section 50, and is moved from a horizontal state to a vertical position. It is designed to rotate in the direction of arrow C until it reaches the state. The hand 58 is connected to the storage section 50
It has a claw structure that can grip the cartridge stored in the cartridge, so that the cartridge can be gripped and released.

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 ball 55.

Now enter the desired cartridge number into the input device of the operation panel 3,
When the number of a desired piece in this cartridge is input and a search start is commanded, the elevating member 56 moves up and down to the position of the drum storing the desired cartridge, and the drum rotates. When the normal image quality cartridge storing the desired cartridge reaches a position where it can be gripped by the hand 58, the rotation of the drum is stopped, and the desired cartridge and the hand 58 are held together.
and face to face. Next, the moving member 57 is advanced to the forward end position, and when the hand 58 comes into contact with the cartridge 10, the hand is operated to grip the cartridge 10.

After gripping the cartridge, the moving member 57 is moved backward, and when the moving member 57 reaches the retreat end position, the elevating member 56 is raised and the moving member 57 is rotated to the upright position. The moving member 57 is in the upright state before the lifting member 56 reaches the top of the ball 55, and then the cartridge 10 is carried up to the internal cartridge receiving member 11 and placed in the first position by the upward movement of the lifting member 56. . The cartridge 10 is moved to 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 cartridge 10 placed in the first position to feed the microfilm out of the cartridge 10, and a desired frame in the microfilm is searched. After using the microfilm of the desired cartridge 10 in the reader part or printer part, when rewinding is commanded, the microfilm is rewound into the cartridge 10, and after the rewinding is completed,
The elevating member 56 holding the cartridge 10 is lowered, and the moving member 57 is rotated 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 next cartridge to be used, the above-described operations are repeated.

On the other hand, when using an external cartridge after using the internal cartridge, insert the external cartridge from the external cartridge insertion slot 5 while searching for the desired internal cartridge or using the microfilm in the internal cartridge. the external cartridge 12 is held in the external cartridge receiving member 13, and the external cartridge 12 is placed in the second position. Then, when a desired frame number in the external cartridge 12 is entered into the keyboard of the operation panel 3 and a search start is commanded, the microfilm of the searched internal cartridge 10 is used and then all of this microfilm is rewound into the cartridge 10. When the feed roller 36 rotates, it contacts the film in the external cartridge 12 placed in the second position and feeds the microfilm out of the cartridge 12.
The desired frame on the microfilm in the external cartridge is retrieved.

Therefore the external cartridge can be used while returning the used internal cartridge, and the reader part of the device,
In addition to being able to use part of the printer efficiently,
The usable capacity of the cartridge can be increased without adding an additional storage section 50.

Next, when the input device is commanded to search for a desired internal cartridge to be used next while the external cartridge is in use, the above-described operation is performed and the desired cartridge is conveyed to the internal cartridge receiving member 11 and placed in the first position. The built-in cartridge to be used next can be kept in standby at the first position. After the microfilm in the external cartridge 12 is used, a search operation is started for the microfilm in the internal cartridge that was waiting at the first position when all of the microfilm was rewound into the cartridge 12. Therefore, by alternately using the internal cartridge and the external cartridge, the device can be used effectively.

In the above embodiment, one external cartridge insertion opening is provided and one external cartridge holding position is provided, but there are at least two external cartridge insertion openings.
It is also possible to provide two positions for holding external cartridges corresponding to each insertion opening, and to selectively feed the external cartridges held at each position to the common passage.
