FIG. 9 is a circuit diagram schematically showing the electrical configuration of the film image reading apparatus 1.

The example shown in FIG. 9 is almost the same as the electrical configuration of the scanner device of Japanese Patent Application No. 7-219066 previously proposed by the present applicant. This Japanese Patent Application Hei 7-219
The scanner apparatus described in Japanese Patent Application Publication No. 066 is for electronically converting any of the 135-type film and the film in the advanced photo system, which have been widely used, into electronic images. This utilizes technology relating to a part of a system for converting a film into an electronic image. Therefore, only the electrical configuration will be briefly described below.

The film image reading apparatus 1 has a scanner section 3 including the power switch 37, the load switch 3, the scanning section 7 and the illumination lamp section 8.
2, a scanning motor 11 for stepwise moving the scanner unit 32 in the horizontal direction, a stepping motor driver 11a for controlling the driving of the scanning motor 11, a load motor 12 for driving the transport table 6, and A carrier drive motor drive circuit 12b for controlling the drive of the load motor 12, a photointerrupter 13 for detecting a rotation amount of the load motor 12, that is, a movement amount of the carrier 6, a set switch 28, An end switch 29, an EEPROM 38 for storing information unique to the film image reading device 1, and a personal computer (not shown) arranged on the back of the film image reading device 1 and connecting the film image reading device 1 to the personal computer. A connector 39, a film transport motor 41 for transporting the film, A film transport motor drive circuit 41a for driving the film transport motor 41, a magnetic reproducing circuit 42 having a magnetic head 42a for reading magnetic information recorded on the film, and a photo reflector 43 for detecting a film disk A photo-reflector 44 for detecting perforation, a photo-interrupter 45 for detecting a running distance of the film, an EEPROM 46 in which information such as a rewind end flag, the number of winding frames, and a focus adjustment value are stored. It performs image processing and transmits and receives signals to and from a personal computer via the connector 39, and has the RISC 31 as control means for controlling each circuit in the film image reading apparatus 1. It is configured.

The illumination lamp section 8 of the scanner section 32 includes an illumination lamp 3 for irradiating the film 30f with light.
4 and an inverter circuit 35 for controlling the amount of light by turning on the illumination lamp 34. On the other hand, the scanning unit 7 of the scanner unit 32 receives the light passing through the film 30f and CCD3 that converts images into electrical signals
3 and an image processing circuit block 36 having a clamp circuit, an amplifier circuit, a gamma conversion type AD converter, and the like.

As described above, the connector 39 is directly connected to the RISC 31 without passing through the communication-dedicated IC, and the data communication with the personal computer is performed by the R
This is configured to be performed by the communication software of the ISC 31. If a plurality of controls are to be executed by software using a single controller, high-speed processing is required. Therefore, a RISC that can execute one instruction in one clock is used here.

In this example, the outputs of the photo-reflector 43 for detecting the film disk, the photo-reflector 44 for detecting the perforation, and the photo-interrupter 45 for detecting the running distance of the film are weak and are affected by noise. For simplicity, a dedicated buffer (indicated by a triangular symbol in the figure) is added to each circuit so that each terminal outputs to the RISC 31.

FIG. 10 is a flowchart showing the operation when the film cartridge 30 is taken out of the film image reading apparatus 1. Here, the operation is referred to as cartridge unloading processing.

When the load switch 3 is turned on when the film cartridge 30 is loaded in the film image reading apparatus 1, that is, when the film cartridge is being loaded, the film of the film cartridge 30 is present in the film reading section 4. To see if
A flag is checked to see if the film has been fed (step S1).

If the film feed flag is on, the subroutine ends and the process returns to the main routine.

If the film feed flag is not set, the load motor 12 is rotated in the direction in which the carriage 6 protrudes (step S2).

Thereafter, the terminal switch 29, which is always on when the transfer table 6 does not protrude, waits until it is turned off (step S3).

That is, the mechanism is set so that the terminal switch 29 is turned off when the carriage 6 projects outside the film image reading apparatus 1 and the film cartridge 30 can be substantially loaded. Therefore, a signal indicating that the termination switch 29 has been turned off is detected here.

When this signal is detected, the load motor 12 is decelerated by electric processing (step S4).
From here, the pulses generated from the photo-interrupter 13 are counted, and it waits until the number of pulses reaches a predetermined number (step S5). When the number of pulses reaches the predetermined number, the load motor 12 is stopped (step S6). ), And return to the main routine.

The state in which the step S6 has been completed is a state in which the transport table 6 is projected outside the film image reading apparatus 1, so that the operation of removing or loading the film cartridge 30 is performed here. Just do it.

FIG. 11 is a slightly modified version of the operation shown in FIG.

That is, FIG. 11 is based on the operation of FIG. 10 described above, but when the film is fed from the film cartridge 30, the process returns to the main routine without performing any processing in FIG. However, the processing is different. Note that FIG.
In FIG. 1, the same parts as those in FIG. 10 are denoted by the same reference numerals, and description thereof will be omitted.

If the film sending flag is set in step S1, that is, if the film is sent from the film cartridge 30,
A subroutine for rewinding the film into the film cartridge 30 is performed (step S7).

When the rewinding of the film is completed, the setting of the film sending flag is canceled for the subsequent processing (step S8).

After the processing in step S8 is completed,
Returning to step S2, the transfer table 6 is moved. Subsequent processing is the same as that shown in FIG.

By performing such processing, the film cartridge 30 can be freely replaced regardless of whether or not the film in the film cartridge 30 has been rewound.

Next, FIG. 12 is a flowchart showing the operation of loading the film cartridge 30 into the film image reading apparatus 1.

When the load switch 3 is turned on in order to load the film cartridge 30 into the apparatus in order to digitize the film image, the execution of this film cartridge loading routine starts.

First, in order to take out the film cartridge 30 already loaded, the above-described cartridge unloading process of projecting the carrier 6 out of the film image reading apparatus 1 is performed (step S11).

Next, a timer is started to measure the time during which the transfer table 6 is in the protruding state (step S1).
2).

After loading the film cartridge 30 on the transfer table 6, the operator presses the load switch 3 to set the transfer table 6 inside the film image reading apparatus 1. In response, the RISC 31 determines whether or not the load switch 3 has been turned on (step S1).
3) If it is not on, it is detected whether or not the terminal switch 29 is on (step S14).

If the termination switch 29 is not on,
It is determined whether or not the timer has reached a predetermined time (step S15), and if not, the process returns to step S13.

If the load switch 3 is turned on in step S13, the termination switch 29 is turned on in step S14, or if a predetermined time has elapsed in step S15, the timer is reset. (Step S16),
An operation is performed in which the load motor 12 is rotated in the reverse direction to draw the conveyor 6 into the film image reading apparatus 1 (step S1)
7).

That is, when the load switch 3 is operated, the retraction of the transfer table 6 is started immediately. When the transfer table 6 is pressed without the load switch 3 being operated, the transfer table 6 is immediately started. 6 is started, and if these operations are not performed, the transfer table 6 is automatically retracted after a predetermined time has elapsed.

After step S16, the operation is the same whether or not the film cartridge 30 is loaded on the transfer table 6.

When the transport table 6 approaches the film reading unit 4 by the rotation of the load motor 12 in the reverse direction, the arm 9e of the shaft cover 9 contacts the rear surface 6c of the transport table 6 and moves backward with the transport table 6. Move to.

At this time, the shaft cover 9 includes the pins 1 k, the cam portions 9 b and 9 c of which are fixed inside the film image reading device 1.
Since it is slidably fitted with 1l, it first moves diagonally downward while resisting the urging force of the spring 27.

More specifically, the state of moving diagonally downward is the state of moving in the same direction as the carriage 6 in the horizontal direction and moving closer to the carriage 6 in the vertical direction. is there. That is, in this state, the engagement shaft 9d of the shaft cover 9
Is lowered vertically with respect to the film cartridge 30, and the engaging shaft 9d engages with the shaft hole of the cartridge spool shaft 30a as shown in FIG.

At the same time, the pin 9f of the shaft cover 9 fits into the hole 6b of the carriage 6, and the relative position between the shaft cover 9 and the carriage 6 is accurately set. The cartridge 30 is accurately positioned in the storage chamber 6a of the transfer table 6.

Thereafter, the pins 1k and 11l engage with the horizontal portions of the cam portions 9b and 9c of the shaft cover 9, and the shaft cover 9 moves only in the horizontal direction together with the carriage 6.

Subsequently, the process waits for the set switch 28 to be turned on (step S18). If the set switch 28 is turned on, a command is issued to the carrier moving motor drive circuit 12b to reverse the load motor 12. Deceleration is applied to the rotation in the direction (step S19). At this time, the carriage 6 is in a state of approaching the film reading unit 4.

Thereafter, a photo interrupter (PI in the figure)
It is written. (3) It is checked whether or not the output of the pulse signal has changed by detecting the output signal of (13) (step S20). If the change has stopped, the conveyance table 6 is moved to a position where it is integrated with the film reading unit 4. When it is determined that the setting has been made, a stop signal is sent to the carrier moving motor drive circuit 12b to stop the rotation of the load motor 12 (step S21).

When the transfer table 6 and the film reading section 4 are integrated, the pins 6h and the positioning holes 4c
Are fitted, the relative positional relationship between the transport table 6 and the film reading unit 4 can be accurately determined.

FIG. 13 is a flowchart showing an outline of a subroutine in which the image recorded on the film in the film cartridge 30 is continuously digitized and taken in by the film image reading apparatus 1.

When the film cartridge 30 is loaded by the operation as shown in FIG. 12 (step S31), the film transport motor 41 is driven by the film transport motor drive circuit 41a, and the film transport from the film cartridge 30 is performed. Is sent to the film reading unit 4 and stopped when the first frame of the film image is located in the exposure window 4b (step S32).

Here, in order to store that the film has been sent to the film reading section 4, a film sending flag is set (step S33).

Next, after the image of the film is scanned and digitized by the scanning unit 7, an operation of transferring the film by one frame to the next frame is performed, and scanning is performed again. By repeating such operations continuously, the last frame of the film is read and digitized (step S3).
4).

When the continuous image capturing operation is completed, the setting of the film feed flag is released (step S35), and this subroutine is terminated.

The reason why the film sending flag is set in the above is to prevent the rewinding operation from being executed during the image taking operation. That is, even if the subroutine of the steps S31, S32, and S34 includes a step of rewinding for some reason, the execution is prohibited.

FIG. 14 is a flowchart showing the operation of rewinding the film in the film image reading apparatus.

In the film rewinding operation, when the film rewinding operation is performed in a state where the film cartridge 30 is loaded in the film image reading apparatus 1, it is determined whether or not the film sending flag is set. The film is rewound into the film cartridge 30 only when the flag is not set.

That is, if there is a step for determining whether or not to execute rewind for some reason in the main routine or another subroutine, the film feed flag must be set at that time. In this case, the rewinding operation is performed. And
Even if one of the routines includes a step of inadvertently determining the execution of rewinding, the execution of this film rewinding subroutine can be prohibited by setting the film feed flag.

When this film rewinding operation starts,
First, it is determined whether or not the film feed flag is set (step S41). If the flag is set, the subroutine is terminated as it is. If the flag is not set, the film transport motor 41 is turned off. It is driven in the rewind direction to start the rewind operation (step S42).

Then, after the rewinding of the film is completed (step S43), when the film rewinding is completed, the drive of the film transport motor 41 is stopped via the film transport motor drive circuit 41a (step S43).
44).
