Abstract

PURPOSE:To use a projecting device efficiently by providing a means which selects and conveys a cartridge to at least two positions of the 1st and the 2nd positions selectively and then returns the cartridge after use to a storage part. CONSTITUTION:When the rewinding of the 1st cartridge 10A is completed, a feed-out roller 36 while rotating contacts the microfilm in the 2nd cartridge 10B placed at the 2nd position and sends the microfilm out of the cartridge to retrieve a desired frame. When the microfilm of the 2nd cartridge is rewound into the 2nd cartridge after use, the 3rd cartridge to be used next is loaded in the receiving member 13 and then the 2nd cartridge is returned to a partition chamber of a specific drum by a clamping and conveying mechanism. Therefore, the microfilm of a cartridge to be used is utilized while the film of a desired cartridge is used or returned after use, and the projecting device is used efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a film projection device incorporating a plurality of film cartridges containing films such as microfiche and roll film.

[Technical background and purpose of the invention]

This type of device searches for and grasps the desired cartridge out of a large number of film cartridges housed and stored in the storage section, transports and loads it into the projection section, and after using the microfilm in the cartridge, returns it to the original storage section. The operation of transporting the product back to the location is performed automatically.

In conventional devices of this type, after using the microfilm in a desired cartridge, it is not possible to search for the next cartridge to be used until the cartridge is returned to its original location in the storage compartment. ) It took a very long time to search until the IJ Tsuji became usable, and the device had the drawback of poor utilization efficiency.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a film projection apparatus that eliminates the above-mentioned drawbacks, allows high-speed searching, and allows efficient use of the apparatus.

〔Example〕

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

FIG. 1 shows a film reader printer equipped with the present invention, and the entire device is composed of an upper machine box 1, a lower machine box 2, and an operation panel 3 for instructing various operations. A screen 4 is provided on the front of the upper machine box 1.

Inside the upper machine box 1, as shown in FIG. 2, there is a car in the lower machine box 2, which will be described later. 1 cartridge receiving member 11 and a second cartridge IO automatically selected from the cartridge storage section.
A second cartridge receiving member 13 that holds the cartridge B in the second position, an illumination unit 15 that illuminates the microfilm sent out from the cartridge IOA or IOB, and an imaging lens 1
6, an image sensor 17, a take-up reel 18, and the like are arranged. The second cartridge receiving member 13 is installed above the first cartridge receiving member 11.

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 passes through the condenser lens 21 and mirror 22 to a microfilm F placed between a pair of glass plates G1 and G2. Projected.

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 17. The image sensor 17 is composed of a light receiving element array such as a CCD, and converts the image on the microfilm into an electrical signal. After the image signal output from the image sensor 17 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.

Figure 3 shows the four microphone film feeding passages.
The microfilm in the cartridge IOA passes through the first passage 31, the second passage 32, and then passes through the glass plates G1 and G.
The microfilm in the second cartridge 10B 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 18. You will be guided to 18. 1st passage 31 and 3rd passage
The passages 33 meet at the second passage 32, and the microfilms of the cartridges 10A and 10B pass through the common second passage 3.
2 is selectively delivered.

A film guide plate is provided along each path 31 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 solenoid (not shown) between a position in which it contacts the microfilm in the cartridge IOA placed in the first position and a position away from the film. Further, the film feed roller 36 is connected to a motor, and the cartridge 10B is placed in a second position by a solenoid (not shown).
Move to a position where it contacts the microfilm inside and a position where it separates from the film.

When using the first cartridge IOA, a search command causes the row 235 to rotate and move to a position where it contacts the microfilm F inside the cartridge IOA, and the leading edge of the microfilm is fed out of the cartridge IOA by the roller 35. , this film F is passed through the first passage 31,
It is fed to the take-up reel 18 through 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, 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 onto the cartridge IOA, a winding shaft within the cartridge IOA is rotationally driven in the winding direction by a motor (not shown).

When using the second cartridge IOB, the roller 36 rotates in response to a search command and moves to a position where it contacts the microfilm in the cartridge IOB,
6, the leading edge of the microfilm is sent out from the cartridge IOB, and this film is fed to the take-up reel 18 through the third passage 33 and the second passage 32, and is taken up on 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 transferred to the second film by the rotation of the take-up reel.
is pulled out from the cartridge and wound onto a take-up reel. When rewinding the microfilm into the cartridge IOB, a winding shaft within the cartridge IOB is rotated in the winding direction by a motor (not shown).

The mark detector 38 is for detecting the counting marks attached to each microfilm and the side of the trench, and is composed of a photoelectric conversion element, and is arranged on 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 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. 4, there is a cartridge storage section 50 that stores a number of cartridges 10,
