A transfer means for transferring, a cartridge detection means for detecting the presence or absence of a cartridge at each position of the cartridge holding member, and a control means for controlling the information recording medium of the cartridge detected first by the cartridge detection means to be transferred to the projection section. The information projection device is characterized by:

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

FIG. 1 shows a film reader printer equipped with the device of the present invention, and the entire device is composed of a first machine box 1 at the top, a second machine box 2 at the bottom, and an operation panel 3 for commanding various operations. A screen 4 and an external cartridge insertion slot 5 are provided on the front surface of the upper machine box 1.

Inside the upper machine box 1, as shown in FIG. 2, there is an internal car automatically selected from the cartridge storage section in the lower machine box 2. IJ edge receiving member 11 and external cartridge insertion slot 5
a second cartridge receiving member 13 that holds the manually inserted external cartridge 12 in the second position, an illumination unit 15 that illuminates the microfilm sent out from the cartridge 10 or 12, an imaging lens 16, and an image sensor. 17, a take-up reel 18, etc. are arranged. Second
The IJ cartridge receiving member 13 is installed above the first cartridge receiving member 11. In addition, the first machine box 1 and the second
The machine box 2 is separable, and the first machine box can also be used alone. The film in the cartridge 10.12 is wound into a roll on a core.

The lighting section 15 includes a lamp 20. It is composed of a condenser lens 21 and a mirror 22, and the light from the lamp 20 is projected through the condenser lens 21 and mirror 22 onto a microfilm F placed between a pair of glass plates G1 and G2. The light transmitted through the microfilm passes through the imaging lens 16, is reflected by the mirrors 25 and 24, and is projected onto the image sensor 17. The image sensor 17 is composed of a light receiving element such as a CLCD, 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 of 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 1o is transported through the first passage 31.
, pass through the second passage 32, and then pass through the glass plates G1 and G2.
The microfilm in the external cartridge 12 passes through the third passage 33, the second passage 32, passes between the glass plates G1 and G2, and is guided to the take-up reel. You will be guided to 18. The first passage 31 and the third passage 33 meet at the second passage 32, and the cartridge 1
0.12 microfilm is transferred to a common second path 32. A film guide plate is provided along each path 60 to 33, and each film is guided along a predetermined path by the film guide plate. 55 and 56 are film feed rollers, 37 is a film guide roller, and 3rd is a mark detector.

The film feed roller 35 is connected to a motor M, 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 56 is connected 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 row 235 to rotate and move to a position where it contacts the microfilm F inside the cartridge 10, and the roller 35 sends the leading edge of the microfilm out of the cartridge 10. The film P is fed to the take-up reel 18 through a first passage 61 and a second passage 62. The winding wheel 18 is driven by a motor when a search command is issued, and automatically winds up the leading edge of the microfilm when it is fed. When the leading edge of the microfilm is wound around the take-up reel 18, the rotation of the roller 55 is stopped and the roller 55 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, the film core within the cartridge 10 is rotated in the winding direction by a rewind motor (not shown).

When using the IJ Soji 12 (external car), the row 256 rotates in response to a search command and moves to a position where it contacts the microfilm inside the cartridge 12, and the roller 56
The leading edge of the microfilm is sent out from the cartridge 12, and this film is passed through the sixth passage 35 and the second passage 5.
2 to the take-up reel 18, and is wound onto the take-up reel 18 in the same manner as described above. When the leading end of the microfilm 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 external cartridge by rotation of the take-up reel and wound onto the take-up reel. When rewinding the microfilm into the cartridge 12, the film core within the cartridge 12 is rotated in the winding direction by a motor (not shown).

The mark detector 58 is for detecting counting marks 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 while sandwiching the film.

The marks on the microfilm have different densities from the surroundings, and when the microfilm is fed, the light incident on the mark detector 38 is interrupted by the marks, so that the mark detector 58 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. 4, there is a cartridge storage section 50 storing a large number of cartridges 10;
A cartridge gripping and transporting mechanism (hereinafter referred to as CHL) 51 is arranged to select and take out one of the cartridges in the storage section 50 and transport it to a first position.

In the cartridge storage section 50, drums 50A to 50F' for holding the internal cartridges 10 in radial alignment are stacked at predetermined intervals, and each drum 50A to 50E'
rotates around a central axis 52.

Each drum is of the same groove construction and has radial compartments for storing each cartridge separately.

CHL 51 is an elevating member 56 that moves up and down in the direction of the arrow along a ball 55 vertically installed near the cartridge storage section 50.
and a moving member 57 that is disposed on the elevating member 56 and moves forward and backward on the elevating member 56 in the horizontal direction (in the direction of arrow B).
and a hand 58 disposed at the tip of the moving member 57 and gripping the cartridge, the device 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 handle 58 and a backward end position where the cartridge gripped by the grip is positioned outside the storage section 50. It is designed to rotate in the direction of arrow C from a horizontal state to a vertical state. The hand 58 has a claw structure that can grip the cartridge stored in the storage section 50, and can grip and release the cartridge.

When the movable 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 movable member 57 is in the upright state before the elevating member 56 reaches the top of the ball 55, and then the cartridge 10 is carried to the first cartridge receiving member 11 by the upward movement of the elevating member 56 and placed in the first position. It will be destroyed.

The IJ jig 10 is held at the first position by a moving member 57 and an 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 the microfilm of the desired cartridge 10 has been used for reading, etc. with a part of the reader or a part of the printer, when rewinding is commanded, the microfilm is rewound into the cartridge 10, and after the rewinding is completed, the elevating member holding the cartridge 1o 56 is lowered, and the moving member 57 is rotated to a horizontal state. The elevating member 56 descends to the drum position where the cartridge is returned,
Once the moving member 57 is in the horizontal state shown in FIG. 4, the used cartridge can be returned to its original compartment by moving the moving member 57 forward.

After this return, if an instruction is given to search for the internal cartridge to be used next, the above-described operations are repeated.

On the other hand, if you use an external car (IJ).

The external cartridge is inserted through the external cartridge insertion port 5 and held by 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 input into the keyboard of the operation panel 3 and a search start is commanded, the feed roller 66 rotates and comes into contact with the film in the external cartridge 12 placed in the second position. The microfilm is fed out of the cartridge 12 and a desired frame is searched for on the microfilm in the external cartridge.

In the above embodiment, the external cartridge is held at one position, but the external cartridge is held at a plurality of positions, and the external cartridge held at each position is selectively fed to the common passage. You can also do this.
