It is attached.

In addition, depending on the type of film, for example, 35 mm film and cartridge film, the size of one screen and the interval between the screens may be different. Therefore, the above-mentioned storage means for storing the screen position of the film as the number of drive pulses from the reference position of the above-mentioned lens CCD holding member 7 is provided. Since this storage means normally stores information specific to the film adapter 30 as an "adapter", it is provided in the film adapter.

Here, in the description of the 35 mm film adapter 30 exemplified above as the first embodiment, for the purpose of comparison with the cartridge film adapter 50, film drive means for moving the film is not particularly provided. . The reason is that the film itself is driven by manually moving the dedicated film carrier, so that the film adapter 30 itself can be manufactured at a lower cost.

Incidentally, if the film drive means, the film drive amount detection means and the like provided in the cartridge film adapter 50 shown below are added in the same manner, it goes without saying that the film can be fed "automatically". is there.

Next, FIG. 4 is an external perspective view of a cartridge film adapter as a film holding device according to the second embodiment of the present invention.

The lock mechanism 69 that locks the lid is configured so that the lid 52 cannot be opened unless the upper piece of the switch member (not shown) is slid in the direction of arrow B. A switch member that interlocks with this lock mechanism is built in, and the switch is turned on / off according to the opening / closing of the lid. Therefore, the operator manually closes the lid 52 to perform the "autoload" operation of the film or Alternatively, the film "rewind" operation can be automatically activated by manually opening the lid.

In the opening 53 for illumination, the screen of the film fed to this opening position is optically read by the film scanner main body (not shown).

A plurality of metal pins 77 that are biased by the leaf springs that come into contact with 8 are attached.

Cartridge film adapter 50 of this example
Receives a power supply for the film adapter and a predetermined control signal for driving the film from the film scanner main body 1 via these electrical contacts, and scans a desired film surface of the cartridge film.

On the contrary, the main body of the film scanner is sent from the cartridge film adapter 50 via the terminal group, for example, "film drive amount information""filminformation""film cartridge information""EEPROM in cartridge". It is also possible to receive "information" or "SW information" attached to the cartridge.

Cartridge film adapter 50 of this example
Is provided with a take-up spool 57 for winding the film drawn from the loaded cartridge on the opposite side of the cartridge storage chamber 51, and the "rotation" and "rewinding" of the film is performed at the center of rotation of the spool 57. The motor 56 that supplies the driving force for performing

The output shaft of the motor 56 is formed by meshing a gear 59 fixed to the shaft and a plurality of gears 60, 61 and 62 with each other. Is transmitted to the gear portion 58 fixed to the lower portion of the spool 57.

On the other hand, in the vicinity of the center of the lower portion of the cartridge storage chamber 51, there is constructed a "gear connection" with the above gear group in order to engage with the spool forming the central axis of the cartridge and rotate the spool. A drive shaft 67 is provided. That is, the drive shaft 67 is indirectly connected to the above-described motor 56 through the gear 65 that is integrally fixed to the gear 66 and meshes with the gear 66.

Further, as shown in the figure, in order to detect the driving amount of the film, a film driven roller 78 extended in a direction perpendicular to the running direction of the film is disposed in contact with the film, and a rod-shaped member runs the film. Rotates with. A disk-shaped member 79 called "PI gear" having a slit of a predetermined pattern in the radial direction is attached to this end portion, and it is arranged so as to sandwich the PI gear with rotation. The PI 80 as a photo sensor repeats the detection of “light shielding” / “non-light shielding”.

Therefore, by counting the output waveform pulses from the PI 80, the running amount of the film can be detected. That is, at a position corresponding to a predetermined portion of the film, a PR81 for detecting a film perforation hole is arranged as shown in order to detect the driving amount of the film traveling, and the film screen position The standard of is detected sequentially.

Further, a film cartridge information detecting PR 82 for detecting the information written on the film cartridge is arranged facing the bottom surface of the cartridge. Further, a magnetic head 83 for detecting magnetic information of the film is provided at a position facing the magnetic data area of the film to read the recorded data. (For details, see FIG. 9A).

The motor 56 and various sensor groups (80, 81, 82) are connected to the electrical contact group 77 by a flexible printed board (not shown). FIG. 5 is a functional block diagram showing the functional outline of the scanner body 1 which is the image input device.

When the 35 mm film adapter (FIG. 3) or the cartridge film adapter (FIG. 4) described above is attached to the main body of the scanner 1, as shown in the figure, the fluorescent lamp 3
Between the lens group 8 and the lens group 8, there is a positional relationship in which the frame of the film is inserted so as to traverse the optical path.

The lens group 8 arranged on the optical path of this optical system has a "three-group structure", and the focus and zoom are adjusted to form a correct image on the CCD 9. The second lens group 8b of the second lens group 8b is moved by the focus motor 24 in the optical axis direction for focusing. The optimum focus position for the adapter is recorded in advance as one of unique information from the storage means (not shown) provided in each of the adapters. Read out). As the drive amount for this focusing, the value adjusted for each adapter is written, so the scanner main body can move its focus position to the absolute or relative position that was read, so The autofocus mechanism for focusing can be omitted.

When the PI 26 as a "focus sensor" for detecting the movement of the focus motor 24 detects the rotation amount of the focus motor 24, the PI 26 sends the data to the connected CPU.

On the other hand, all the groups 8a to 8c are driven by the zooming motor 25 to perform the zooming operation. Further, the PI 27 as a “zoom sensor” for detecting the movement by the zooming motor 25 is
When the rotation amount of 5 is detected, the data is sent to the CPU.

Further, not only the scanner main body 1 as an image input device but also the operation of the entire scanner device with each adapter is provided in the main body for the CPU 23 to integrally control.

FIG. 6 is a block diagram showing the outline of the cartridge film adapter 50. The CPU 101 of the cartridge film adapter 50 controls the entire cartridge film adapter as an adapter for the main body 1 (not shown) and controls the CP on the main body side.
Predetermined data communication control with U (not shown) is performed.

In the storage means 102 connected to the CPU, the cartridge film adapter information (for example,
Focus position, etc., the current state of the cartridge film adapter (for example, the number of film frames, and during feeding,
A flag indicating that the air is being fed or being rewound) and other magnetic data are stored.

This storage means 102 is, for example, EEPR.
It is composed of a non-volatile memory such as an OM and a flash ROM, or a backup RAM. The film 104, which is pulled out from the film cartridge 103 as shown in the drawing, is wound around a spool 105, and a magnetic head 106 is in contact with a predetermined position on the film surface.

Magnetic data is recorded on this film 104, and one or a plurality of perforation holes formed at the end of the film are arranged for each frame, and the number of perforation holes at the time of film feeding is set. The film feeding control is performed while counting.

At the same time, while the film is being fed, the magnetic data of the film 104 is read and reproduced by the magnetic head 106, and the magnetic reproduction circuit 107 performs the analog signal amplification process and the digital signal conversion process.
To the signal data.

Motor 1 that exerts the driving force for film feeding
08 is controlled by the motor control circuit 109 based on a control signal from the CPU 101. The motor 108 is "geared" to the film cartridge 103 and the spool 105 via a gear train (not shown).
The film is “wound” by rotating the motor 108 “forward” and the film is “rewound” by rotating it “reversely”.

When the user manually turns on the forced rewind SW 112 as desired, the CPU 101
Instructs the motor control circuit 109 to "reverse" the motor 108 so as to forcibly rewind the film 104 into the cartridge 103.

The PI (photo interrupter) 110 and the photo interrupter control circuit 111 that controls the PI (photo interrupter) 110 are
The perforation holes formed in the film 104 are detected, and the detection signal is supplied to the CPU 101.

Incidentally, the above-mentioned film cartridge 103
At the bottom of the data disc, there is a data disc described later, which is recorded in a predetermined pattern (see FIG. 12B) so that the "type", "exposure sensitivity", "number of shots", etc. of the film can be discriminated. Although not shown, this pattern is detected by a predetermined optical sensor (82 in FIG. 4).

Next, the operation of the above-mentioned cartridge film adapter will be described with reference to the flowchart of FIG. The cartridge film adapter starts the following processing procedure when mounted on the scanner body.

First, as an initial setting of this adapter, CP
Initialize the RAM in U and each related port (S1)
00). Next, necessary data is read (as an initial operation) from the storage means (S101). Here, as an example, an EEPROM is used as a storage means, but a flash ROM or a RAM backed up by a battery may be used instead.

Cartridge film adapter information (focus position data) as data: information relating to the state of the cartridge film adapter (for example, a flag indicating the number of film frames being fed, rewound, or idling) and the previously read magnetic field. If the data is stored, that magnetic data is read out.

In the first communication (1) with the main body CPU (S102), it is notified that the cartridge film adapter is mounted, the data read in step S101 is transmitted, and various data from the main body CPU is transmitted. The second communication (2) for receiving the command is performed (S103).

In step S104, it is determined whether or not a film is loaded in the cartridge film adapter. If it is not loaded, the process proceeds to step S105, while if it is loaded, the process branches to step S108.

Next, it is judged whether or not the film is loaded (S105). If the film is not yet loaded here, the process returns to step S103, while if the insertion of the film is detected, the process branches to the subsequent step S106.

In step S106, the film is "idle-fed" to be fed to the first frame and the magnetic data corresponding to the first frame is read out. Where EEPROM
The magnetic data in the data is initialized and the data of the first frame is recorded in advance (S107).

Next, it is determined whether or not the film is fed (S108). In this determination, when the feeding command is received from the main body CPU in step S103, step S
If not, go to step S110 described below.
Branch to.

Then, "film feeding" which will be described later in detail is performed (S109). Here, it is determined whether or not the film is rewound (S110). When a rewind command is received from the CPU of the main unit, and forced rewind S
If W is operated, the process proceeds to the following step S111, and if not, the process branches to step S103.

The film is "rewound" (S11).
1) In this rewinding, the motor is rotated in the reverse direction, and motor driving is instructed until the film is completely wound into the cartridge.

Next, the above-mentioned routine "film feeding (S109)" will be described with reference to FIG. When a signal command, for example, "feed the film to the nth frame" is delivered from the CPU of the main body in step S103 described above, the processing steps of the following procedure are executed.

The target number of frames sent from the main body CPU and the current number of frames are acquired (S200), and it is determined whether the number of target frames and the current number of frames match (S201).
As a result, if they match, step S213 described later.
If there is still no match, the process proceeds to the next step S202.
Proceed to.

In this step S202, the previous step S
If the result of comparison in 201 is "target frame number> current frame number", the process branches to step S206, while if "target frame number <current frame number", the process proceeds to step S203.

In step S203, the motor is instructed to "reverse" and the film is fed in the "rewind" direction. Here, when feeding in the rewinding direction, the magnetic data is not read. This is because the magnetic data is read when the frame is wound and the data is already stored in the EEPROM.

Wait until one frame is fed (S20
4) When the feeding of one frame is completed, the next step S2
Go to 05. The motor is stopped (S205), and the rewinding for one frame is completed.

In step S206, the motor is "normally rotated".
Then, the film is fed in the "winding up" direction. Then, it is determined whether the magnetic data of the frame to be fed has already been read (S207). If the relevant magnetic data has already been read, step S
It branches to 209. On the other hand, "reading of magnetic data" is executed only when the reading has not been completed yet (S208).

In step S209, this step is repeated until one frame is fed, and when the feeding of one frame is completed, the process branches to the next step S210. In step S210, the motor is stopped to complete the winding of one frame.

Then, it is judged whether or not the magnetic data is read (S211), and if the magnetic data is not reproduced, the process directly returns to the first step S200 of this routine. On the other hand, if the reading is executed, the following step S21
2, the magnetic data is stored in the EEPROM (S21
2) and thereafter, similarly to the beginning step S20 of this routine
The process returns to 0 and the series of processes described above is repeated.

As described above, "winding one frame" or "rewinding one frame" is repeated, and when the number of target frames is reached, the process branches to step S213 and the magnetic data of the target frame is changed to E.
It is read from the EPROM (S213).

In the next step S214, when the magnetic data is transmitted to the CPU of the main body (S214), the film feeding process is ended and the routine is returned to the called routine.
Next, "magnetic data reproduction" after step S206 described above will be described with reference to FIGS.

FIG. 9A shows the positional relationship between the magnetic head and the magnetic data portion on the film. A magnetic data area 402 is formed in the longitudinal direction of the lower end of the film 401, and two perforation holes 403 are formed in each frame at the upper end. In the center, the exposed area 4 of the film where the image is recorded
04 is formed.

Detection of these perforation holes is
The illustrated PR (photo reflector) 405 performs this. The magnetic head 406 reproduces the data written in the magnetic data area.

FIG. 9B shows the waveform of the magnetic data reproduced by the magnetic head 406 and the corresponding time series and binarized data. Waveform (i) represents the signal read from the magnetic data area on the film by the magnetic head. The minus side of this signal is detected as the "clock (Clk) edge" shown in waveform (ii), and the plus side is also detected as the waveform (ii
It is detected as a "data edge" shown in i).

The time from "Clk edge" to "Data edge" or "C edge" to "C"
The time-series result of measuring the time to "lk edge" is shown in the diagram (iv).

The time from the "Clk edge" to the "Data edge" and the time from the "Data edge" to the "Clk edge" are represented by binary numbers "0" and "1", respectively. For example, when the time from the Clk edge to the Data edge is longer than the time from the Data edge to the Clk edge (that is, t0>
t1) is defined as "0", and vice versa. The diagram representing the result of this binarization processing is the diagram (v) below it.

Further, (i) to (iii) of FIG. 10 respectively show the motor drive and the sensor P during magnetic data reproduction.
A time chart regarding the detection signal of R and the magnetic data to be reproduced is shown.

When the motor is driven in the normal direction (i), the PR detects the presence of the perforation hole, and the output of the sensor PR changes from L (Low) → H (High) → L (Low). Here, it is sensed that the magnetic data area starts from the change point where the PR output changes from H to L. (Ii).

Subsequently, when the film is further fed while the magnetic data is reproduced by the magnetic head, the sensor P
R detects the next perforation hole, and at this time, PR
The output changes from L → H → L. Therefore, the PR output is L
It is possible to recognize that it is the end of the magnetic data area by the change point changing to → H. At this point, the motor is stopped in order to finish the film feeding for one frame at the change point where the PR output changes from H to L.

FIG. 11 is a flow chart showing a reproduction processing procedure by the routine "magnetic data read (S208)". The standby loop (S411) waits until the film feeding is restarted and the PR output "falls", and when it falls, the process proceeds to the following step S412, and this time waits for the generation of the clock edge of the magnetic data (S
Wait at 412).

When the clock edge arrives, in the next step S413, the first timer 1 for measuring the time from the clock edge to the data edge is started. Next, the data edge is waited for in the wait loop (S414), but if it is not done yet, the rising edge of PR comes to the wait loop (S41).
If the PR rises at this point, it indicates the end of the magnetic data area. Therefore, the above series of processing is ended and the routine is returned to the called routine (S424).

In step S414, if the data edge comes, the process proceeds to the next step S416. Then, the timer 1 is stopped and the time from the clock edge to the data edge is measured (S416).

Then, the second timer 2 for measuring the time from the data edge to the clock edge is started (S417). Similarly, the clock edge is waited for in the standby loop (S418).
Waiting for the rising edge of the standby loop (S419), and if PR rises here, this means the end of the magnetic data area.
It returns to the routine that has been called (S424).

The timer 2 is stopped and the time from the data edge to the clock edge is measured (S420). The measurement times of timer 1 and timer 2 are compared (S421).
Here, if timer 1> timer 2, the process proceeds to the next step S422, and it is determined that the binary data is “0”. On the other hand, if timer 1 ≤ timer 2, then the process branches to step S423 to determine that the binary data is "1".

As described above, the above steps S413-.
By repeating S423, the reproducing process of the magnetic data is performed. When the "PR rise" is detected in step S415 or step S419 of this routine, the flow advances to step S424 to wait for the "PR fall". When this fall of PR is detected, after this routine is terminated and returned, the motor is stopped in step S210 of the above description after the completion of one frame processing,
Film feeding ends.

Next, with reference to FIGS. 12A to 12C, the bar code written on the data disk of the film cartridge and the reading mechanism thereof will be described. FIG. 12A shows a bar code formed on the end surface of the film cartridge and a PR (photoreflector) 304 as a mechanism for reading the bar code.

Information such as the type of film, exposure sensitivity and the number of film frames is written in the film cartridge 301 in the form of a bar code on the data disk 302 on the end face. This data disk 302 is a motor 303
Is operated to rotate in synchronization with the rotation of the rotation axis of the film cartridge. The PR 304 optically detects the difference in reflectance between the patterns written on the data disc.

FIG. 12B shows an example of the pattern in the above data disk. The data disc is composed of a portion with high reflectance (white portion in the figure) and a portion with low reflectance (black portion in the figure), and the binary angle "0" and " Represents 1 "data, small angle is" 0 ", large angle is" 1 "
Is set, and the angle ratio has a ratio of 1: 2 or more.

The white left half shown in the figure is an area for detecting the start and end of the data. When this data disk is rotated counterclockwise as shown by the arrow in the figure, a digital signal as shown in FIG. 12C is obtained as the output of PR.

Here, the high reflectance of the data disk (
White (white) part is L (Low) output, low reflectance (black) part is H
(High) output. The time width of each of L and H is measured and "0" or "1" of the corresponding data is identified. This data is for film type (ie negative, positive,
(Monochrome), exposure sensitivity, and the number of shots are coded, and decoding processing is performed according to a predetermined format.

This format is composed of 13 "0" s and "1" s, which are appropriately combined, so that there is no continuous pattern in which all are "0s" or "1s". It is specified that when the pattern data is read out, a pattern having a short width (that is, an angle) and a pattern having a long width appear alternately.

Next, FIG. 13 is a flow chart showing the procedure relating to the above-mentioned data disk read processing.
First, an area for storing a timer value described later is initialized (S301).

The motor is rotated in the reverse direction, whereby the data disk also rotates counterclockwise (S302). Wait, which is the time from when the motor is driven until the rotation is stabilized, is entered (S303).

A change in PR is detected (S304), and if there is a change, a timer is started (S305). A change in PR is detected (S306), when there is a change, the timer is stopped (S307), and the data is sequentially stored in a storage area secured in advance (S308).

It is determined whether the data is the 14th time (S30).
9). Since the data disk makes one round with 13 data and an area that serves both as a start and an end, when the data disk reaches 14, the motor is stopped (S311) and the reading of the data disk is completed. If the number is less than 14, a predetermined timer is started (S310) and the above-mentioned step S30 is performed.
Return to 6.

While repeating the above steps S306 to S310, the reading operation written on the data disk attached to the film cartridge is performed. Following the motor stop (S311), the read analog data is converted into "0" and "1" (S312).

Here, an example of data is shown in FIG. First, assume that the read data is (i) in FIG.
Find the longest data from the data (S31
2). This is the sixth "180" from the left in FIG. 14 (i).
Corresponds to that. In step S313, the longest data is brought to the head. As a result, the data string of FIG. 14 (i) is shifted to the left by 5 like the data string of FIG. 14 (ii), and the 5 data that were initially on the left of “180” are moved to the end. Rearranged.

Next, the data Max (maximum) and Min (
(Minimum) is searched (S314). Since the leftmost "180" is the data showing the start and end, this work is 2
When performed on the 14th to 14th data, Max is 4
12th and 12th "22", Min is 11th and 13th
The second is "8". For example, an intermediate value (= 15) between Max and Min is calculated. (S315). This is "22"
An intermediate value between "8" and "8" is calculated and set to "15" in this case.

The binary "0" or "1" is determined. This sets long data to "1" and short data to "0" with the intermediate value of Max and Min obtained previously as a boundary (S316). The data obtained as a result is replaced with the data of "0" and "1", and a binary data string as shown in FIG. 14 (iii) is obtained.

Next, the "decryption process" of the data is performed (S
317). This determines, for example, "film type", "exposure sensitivity" and "number of shots" in accordance with a predetermined format for the data array obtained up to step S316.
