In FIG. 1, reference numeral 1 denotes a part of a film holder, which is a lower plate for storing a film original, 1a is a slide storage unit for storing a slide type film, 1b is a sleeve storage unit for storing a sleeve type film, and 1c is for reading a film original. 1d is a detection window for detecting the presence or absence of a slide film, 1e is an engaging portion, 2 is an upper plate which is a lid for pressing a film original, 2a is a portion for pressing a slide film, and 2b is a film original for reading. Windows for openings,
Reference numeral 2c denotes a locking claw for hooking the locking portion 1e when the upper plate 2 is stacked on the lower plate 1, 3 denotes an elastic member for pressing a sleeve type film, and 4 denotes an elastic member similar to 3.

FIG. 2 is a view showing a slide film 8 which is a kind of a read original.

FIG. 3 is a view showing a state in which one slide film 8 is loaded in the film holder shown in FIG. In FIG. 3, the slide film 3 is housed in three slide storage portions 1a of the lower plate 1, the upper plate 2 is closed, the slide film is pressed by the film pressing portion 2a, and locked by the locking portion 1e and the locking claw 2c. Is done.

FIG. 4 shows a film holder of the same type as the film holder shown in FIG. 1, in which an upper plate 5 for holding a slide film 8 is provided with a film resilient portion 5a. That is, this is a modification of the film holder of FIG.

FIG. 5 is a view showing a state in which a film 9 of a sleeve type different from the slide film is loaded in the film holder shown in FIG. In FIG. 5, when the upper plate 2 is closed, the elastic members 3 and 4 press the outside of the reading screen of the sleeve film 9.

FIG. 6 shows a film holder which is another modification of the film holder of FIG. 1. Reference numeral 6 denotes a lower plate, 6a denotes a storage portion for a slide film, 6b denotes a storage portion for a sleeve film. However, the depth is set in consideration of the thickness of the slide frame.

FIG. 7 is an external view of the main body of the film scanner for reading a film image held in the film holder shown in FIG. 1 and FIGS. In FIG. 7, reference numeral 100 denotes a film scanner main body; 27, a film holder holding a film original;
Insert and read the image.

FIG. 8 is a schematic diagram showing the configuration of the film scanner system of this embodiment. In the figure, 100 is a film scanner main body, 21 is a lens which is an imaging optical system, 22 is a line CCD sensor which is disposed on a focal plane of the lens 21 and performs photoelectric conversion, and 23 is an optical axis of the lens 21 at 90 °. A mirror bent 24 degrees; a cold cathode ray tube as illumination means; 25, a film holder carriage movable across the optical axis of the lens 21; 26, a moving means for moving the film holder carriage 25; Step motor. Reference numeral 27 denotes a film holder, which reads an image by holding the film 23 and inserting the film 23 into the film holder carriage 25. 28 is a guide shaft for guiding the direction of movement of the film holder carriage 25,
Reference numeral 29 denotes an image processing board (first board) for controlling the whole of the film scanner device and performing signal processing; 30, a power supply board (second board) for supplying power to the apparatus from an input power source; A power supply cable 32 for supplying power to the apparatus from the outside, and a communication cable 32 for outputting an image signal to another apparatus or inputting a command from the other apparatus.

Next, the case of reading an image on the film 33 will be described. From the insertion slot 34 to the film holder 2
7 is inserted into the main body 100 of the film scanner. An alternating current is supplied to the power supply substrate 30 via a power supply cable 31, and supplies necessary power to the image processing substrate 29. When reading is started, the cold-cathode tube 24 is turned on, the light transmitted through the film 33 is bent 90 degrees by the mirror 23, and the line CCD sensor 2 is
2 is imaged. Then, the image signal is converted into an image signal in the line CCD sensor 22, a predetermined process is performed on the image processing board 29, and an image signal for one line of an external connected device is output. Subsequently, the film holder carriage 25 is moved by a distance corresponding to one line by the step motor 26, and reads the image of the next line. By repeating the above operation, an image signal for one frame of the film is output.

FIG. 9 is a perspective view of the film scanner main body 100 shown in FIG. 8 as viewed from above. FIG. 9 shows a state in which the imaging lens 21 is in focus on the film 33. If the position of the film 33 changes due to the difference in the thickness of the slide mount, the line CCD
The image formed on the sensor 22 is a blurred image with a low resolution, and the read image is of poor quality.
As a method for preventing this, it is only necessary to change the position of the film or to provide a means such as an auto focus for changing the positions of the lens 21 and the line CCD sensor 22, but the cost is high.

As described above, according to the present embodiment,
One type of film holder for holding films of different types, which has been a problem in the past, can be shared by one type, and the effect of reducing costs and the fact that it is not necessary to use a plurality of types of holders at the time of use, it is easy to use. Has a good effect.

Further, according to the film holder of FIG. 6, both the film surface of the slide-type thick original and the film type of the sleeve-type film original can be made substantially the same, and an image which does not require much resolution can be obtained. In this case, there is an effect that focusing can be omitted. There is an effect that the amount of adjustment can be reduced even when focusing.

Further, there is an effect that the holder of the slide type film and the sleeve type film which are usually used most commonly can be used.

Also, a slide film having a large outer shape is used.
By arranging every other with respect to the frame position of the sleeve type film, it is possible to double as the opening window provided in the film holder, and when holding both types of film, with the minimum size, There is an effect that the slide film can be held most.

[0030]

As described above, according to the present invention,
A film holder capable of holding a plurality of types of films and a system using the film holder can be provided.
