Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film holder for holding a film and an image reading apparatus using the film holder.

[0002]

2. Description of the Related Art Conventionally, when an image on a film is read by an image reading device such as a film scanner, there is a method of storing the film in a film holder and mounting the film holder to read the image on the film.

At this time, if the film to be read is curled (curved in the longitudinal direction) or warped (curved in the lateral direction), it may be difficult to be pinched by the film holder and may be damaged. As an improvement of this, a film holder provided with a member for preventing the film from rising is proposed as disclosed in Japanese Patent Laid-Open No. 10-145550.

[0004]

However, the above-mentioned conventional example has the following problems. Normally 4 to 6
By inserting the long film, which is cut into frames, into the holding portion and the member for preventing the lifting of the leading edge of the film, the lifting of the film can be prevented. However, when the film is warped, there is a problem that the film cannot be pinched accurately because the deviation in the lateral direction of the film cannot be regulated.

In addition, when the frame position of the film is aligned with the opening of the film holder, if the position of the film and the member for preventing the floating is separated, the film is once sandwiched in the film holder and then the separated position. However, it took time and effort to re-align the frame positions.

[0006]

The present invention has been made to solve the above problems, and in the film holder according to claim 1, a film in which image portions are sequentially arranged in the longitudinal direction can be attached and detached. A film holder that holds a film, a film holding surface that holds the film, an opening that exposes an image portion of the film, and a film holding member that has members for abutting one end of the film and holding both corners thereof. A film pressing member that fits into the film holding member via the film to hold the film, and releases the film by releasing the fitting with the film holding member. Characterize.

According to another aspect of the image reading apparatus of the present invention, a document table on which a film holder can be placed, a light source for irradiating the film mounted on the film holder, and a light source for reflecting the film or transmitting the film are used. It is characterized in that it has a reading unit capable of reading the light.

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) A film holder of the present invention and an image reading apparatus using the same will be described with reference to FIGS. 1 to 5.

FIG. 1 is a schematic plan view of the film holder of this embodiment. As shown in FIG. 1, the film holder 1
Is composed of a film holder body 10 and a film retainer 20. The film holder body 10 and the film retainer 20 are connected by a hinge 24, and the film retainer 20 can be opened and closed with the hinge 24 as a fulcrum.

The film holder body 10 has a film 3
Film storage unit 11 for storing 0, film 30
A film supporting portion 12 for holding the both ends of the film supporting portion 12 at the abutting position of the front end of the sheet, a shading window 14 for obtaining shading data, an opening 16 for reading the film, and a nail provided on the film retainer 20. A claw receiver 15 for receiving 25 is provided.

The film retainer 20 is provided with a film fine adjustment window 22 and a film reading opening 26.

FIG. 2 is a schematic perspective view of the film holder of this embodiment. As shown in FIG. 2, when the film 30 is attached to the film holder 1, the film retainer 20 is opened, and the leading end of the film 30 is inserted between the film storage portion 11 and the film support portion, and is inserted until it abuts. When the hand is released from the film 30 as it is, the film 30 is stored in the film storage portion by its own weight.

Further, the film retainer 20 is closed, and all the claws 25 are fitted into the claw receivers 15 so that the film 3
0 is fixed to the film holder 1.

FIG. 3 is a schematic enlarged view of the film holder of this embodiment. As shown in FIG. 3, the film support portions 12 are installed at both ends of the film storage portion 11. The film support portion 12 has an arbitrary width and length, and can reliably hold both ends of the film 30 even if the inserted film 30 is curled or warped.

FIG. 4 is a schematic sectional view of the film holder of this embodiment. As shown in FIG. 4, the film 30 strikes the film support 12 between the film support 12 and the film storage 11. The distance between the abutting position of the film 30 and the opening 26 is set close to the distance between the leading end of the film 30 and the first frame position. Therefore, insert the film 30 into the film support portion 12,
Positioning of the film 30 can be easily completed by abutting.

FIG. 5 is a sectional view of the image reading apparatus of this embodiment. As shown in FIG. 5, the image reading device 40 includes a document table glass 44 on which the film holder 1 is placed, a transillumination unit 50 above the document table glass 44, and a carriage 60 below the document table glass 44. It is configured.

The transparent original unit 50 includes a reflection sheet 5
2, a light guide 53, a visible light illumination lamp 54, an infrared light illumination LED 55, and a light source protection member 56 are mounted respectively. The reflection sheet 52 and the light guide 53 are for guiding the light emitted from the visible light illumination lamp 54 or the infrared light illumination LED 55 onto the surface of the film 30 disposed below with uniform brightness. It is a thing.

The carriage 60 includes a lamp 6 for reflected illumination.
2, a CCD line sensor 64, a lens 66 and a reflection mirror 68 are mounted respectively. The CCD line sensor 64 converts an image into an electric image signal, and has a plurality of image pickup elements arranged in a straight line. The carriage 60 is engaged with the carriage guide shaft 42 and is movable in the sub scanning direction.

Therefore, the document table 44 of the image reading device 40
After mounting the film holder 1 in which the film 30 is stored, the visible light lamp 54 or the infrared light LE
The image of the film 30 can be read by moving the carriage 60 while turning on the D55 or the reflection illumination lamp 62 and continuously converting the light transmitted or reflected by the film 30 into an image signal by the CCD line sensor 64. become.

[0020]

As described above, according to the present invention, it is possible to obtain a film holder in which a film having a curl or a warp can be reliably accommodated and which can be easily positioned, and an image reading apparatus using the film holder. .
