BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film image reading apparatus for reading an image on a developed film.

[0002]

2. Description of the Related Art The above-mentioned film image reading apparatus (for example, a film scanner) reads an image of a developed film by an image pickup device such as a line sensor and displays the image on a monitor or the like.

Here, a 35 mm film, which is a conventional general film format, is cut into six sleeves after development and formed into a sleeve form, or cut off one frame at a time and fitted into a frame to form a mount form. Or most. For this reason, existing film image reading apparatuses are also configured to correspond to these modes.

For example, as shown in FIGS. 10 and 11, in a current film image reading apparatus, a film in a mount form is directly inserted into a film insertion opening 101, and a film 103 in a sleeve form is inserted as shown in FIG. After being sandwiched between the film carriers 102, the entire film carrier 102 is inserted into the film insertion opening 101.

As film formats other than the 35 mm film, there are a brownie plate film, a 4 × 5 size film and the like, and a film image reading device dedicated to these film formats has also been commercialized.

Further, as disclosed in US Pat. No. 4,841,319, a developing device such as a film of a so-called thrust type cartridge in which a spool in a cartridge is driven to unwind and rewind the film into the cartridge. There is also a film format of a type that is housed in a cartridge later, and a film image reading device for this cartridge housing film has been proposed.

However, since it is inconvenient to prepare a dedicated film image reading device for each film format, there is a demand for a film image reading device capable of handling a plurality of film formats.

For this reason, if a film image reading apparatus compatible with both of these film formats is to be manufactured, a film path and a film feeding mechanism dedicated to each format are required, and a film illumination system dedicated to each film path is also required. In addition, when the photographing screen size differs between the cartridge housing film and the 35 mm film, a mechanism for changing the imaging magnification of the imaging optical system for each format is required. For this reason, there is a problem that the number of components in the film image reading apparatus is increased and the mechanism is complicated, which leads to an increase in the size and cost of the apparatus.

In the case where a film in the form of a sleeve is to be read by the above-described film image reading apparatus for 35 mm film, the film carrier normally stored in a closed state is once opened, and the film is inserted.
Since the operation of closing the carrier must be performed again, it is troublesome, and there is a problem that the film surface is easily stained during the operation.

FIG. 6 shows a state in which the cartridge stage film attachment is mounted on the movable stage 4. Hereinafter, the computer C shown in FIG.
The operation of the scanner will be described with reference to the operation flowchart of FIG.

First, when an operation of starting film reading is performed in the computer C, a drive signal is sent from the computer C to a stage drive circuit (not shown) in the scanner main body 1 (step 1). The stage drive circuit which has received the drive signal operates the motor 20 to rotate the drive shaft 3, and moves the movable stage 4 to the position where the reading window 1a faces the end of the aperture 35c of the attachment mounted on the movable stage 4 (hereinafter, referred to as the movable window 4a). , The initial position: FIG.
To the middle position in the direction A).

When the cartridge 36 is loaded in the cartridge chamber 35a of the attachment, a loading signal is output from the sensor 37. This loading signal is transmitted to the electric block 35.
e and the electrical contacts 5 are sent to the scanner body 1 and further sent to the computer C connected to the scanner body 1.

When the computer determines that the loading signal has been input (step S2), it sends a film loading signal to the scanner body 1 (step S2).
3). This signal is sent from the scanner body 1 to the feed drive circuit (not shown) via the electric contact 5 and the electric block 35e, and the feed drive circuit is provided in the attachment for driving the cartridge spool 36b and the take-up spool 35i. Activate a motor (not shown). When the spool 36b in the cartridge is driven to rotate, the film 36a is paid out from the cartridge 36. Then, when the leading end of the film 36a is wound around the rotating take-up spool 35i, the film 36a is pulled out of the cartridge 36 by the rotation of the take-up spool 35i thereafter.

When the screen of the first frame of the film 36a reaches the position facing the aperture 35c, the 1st frame is displayed.
The perforation corresponding to the frame is the photo sensor 38.
, And a positioning signal is output from the photo sensor 38. This positioning signal is sent to the scanner main body 1 and further to the computer C via the electric block 35e and the electric contact 5. When the computer C determines that the positioning signal has been input (step S4), the computer C sends an image pickup signal to an image pickup drive circuit (not shown) mounted in the scanner main body 1 to turn on the fluorescent tube 2 and to turn on the CCD.
The line sensor 19 is operated (Step 5). Also,
The computer C sends a drive signal to the stage drive circuit, and moves the movable stage 4 and the attachment in the direction B (in the direction of the film surface) at a predetermined speed. Thereby, the CCD line sensor 19 reads the image of the first frame for each portion facing the reading window 1a, and
To output an image signal.

The image signal for each portion output from the line sensor 19 is stored in the computer C, and the computer C reproduces the entire image of the first frame on the monitor M based on the stored image signal (step S1). 6).

The computer C has a CCD line sensor 1
When it is determined that the image reading of the first frame by step 9 has been completed (step 7), it is determined whether or not the frame from which the image has been read is the last frame among the set frames (step 8). If so, a predetermined end operation such as rewinding of the film is performed, and the flow ends. If it is not the last frame, a drive signal is sent to the stage drive circuit, and the movable stage 4 and the attachment are returned in the direction A (toward the initial position) (step 9).

The computer C includes a movable stage 4
Is returned toward the initial position, a drive signal is sent to the feed drive circuit in the attachment via the electric contacts 5 and the electric block 35e to rotate the take-up spool 35i and feed the film 36a. (Step 10). Here, for example, when the image of the third frame is reproduced by skipping the second frame, the fact is input to the computer C, and the computer C
, It is detected that the screen of the second frame has passed through the aperture 35c, and the screen of the third frame is
When it reaches the position opposing c, the drive signal is cut off to stop the film feeding.

As described above, while the movable stage 4 is being returned toward the initial position, the frame is fed by the film 36a, so that the image reading of the next frame can be started quickly. Therefore, image reading of a plurality of frames can be performed in a short time.

When the computer C determines that the movable stage 4 has returned to the initial position (step S1).
1) The process proceeds to step 4 to read the image of the next screen.

When a 35 mm film attachment is mounted on the movable stage 4, the image of each frame is read in the same manner.

As described above, by preparing an attachment for each film format, the imaging optical system (1)
7, 18, 19) and the illumination system (2) can be shared for all film formats. For this reason, compared to the case where a dedicated imaging optical system and illumination system are prepared for each format,
The number of parts can be reduced, and the configuration can be simplified.
