In the first and second embodiments listed above, the "original image" to be input is not particularly limited, and may be an optically readable original. Any form of manuscript may be used.

Therefore, if the original is, for example, a developed film (that is, a negative / positive film), the scanner device of the present invention can be applied as a "film scanner device". That is, the device of the present invention can be applied as a scanner device including a film image input device (1) and a film holding device (100) as a detachable film adapter.

The "film scanner device" as a specific example will be described in detail below. That is,
FIG. 2 is a perspective view showing the internal structure of an image input apparatus 1 as an apparatus main body for capturing a film image, for example, which constitutes the scanner apparatus according to the present invention.

The groove portion 2 in the figure is a portion formed for detachably mounting a film original document holding device (not shown) (details will be described later). A line AA in the figure indicates the center of the optical path of the optical system of the image input device 1, and on this optical path, the fluorescent lamp 3 as the above-mentioned illuminating means and the linear as the image pickup means are also provided. The CCD 9 is arranged with a film surface (not shown) that will be arranged in the groove 2 as a boundary.

In the fluorescent lamp 3 for illuminating the film, the fluorescent tube is bent in a "U" shape in the vicinity of both ends in order to improve space efficiency. The fluorescent lamp 3 is pressed and held by a fluorescent lamp holding member 4 against a reflector member 5 having a "V-shaped" groove, and further passes under a film holding device to a lens CCD holding member 7 (base). It is a fixed and integrated structure that behaves the same as this base 7.

The film image illuminated by the fluorescent lamp 3 passes through the optical lens 8 for forming an image on the linear CCD 9 and is converted into an electric signal by the CCD 9 in a correct image.

The output signal of the linear CCD 9 is transmitted to the main board 17 laid on the bottom surface of the device via the flexible printed board 14 in the figure. The cable connector 22 is connected to the main board 17 by a flat cable or a lead wire, and is connected to a communication connector (for example, R
S232c) is provided so that an interface between an external device (for example, a PC) and this device is also possible.

The lens CCD holding member 7 has a parallel screw shaft 15 and a guide shaft 1 penetrating the base.
It is movably held by 6. The screw shaft 15 has a spiral groove having a predetermined pitch, and the lens CCD holding member 7 is screwed into the spiral groove so that the screw shaft 15 can move in parallel in the axial direction of the guide shaft 16.

Therefore, when the screw shaft 15 is rotationally driven by a predetermined method, the lens CCD holding member 7 together with the fluorescent lamp 3, the lens 8 and the linear CCD 9 are screwed while maintaining the mutual positional relationship. Shaft 15
By moving in parallel to the axis direction of, the sub-scanning of the film surface as the document is performed.

The screw shaft 15 is used for the gear 1
It is connected to the stepping motor 18 via 9 and 20, and the rotational driving force of the stepping motor 18 is transmitted to the screw shaft 15.

The initial position and the end position of the lens CCD holding member 7 are detected by an optical sensor (not shown),
The absolute position where the lens CCD holding member 7 is located is detected from the predetermined reference position and the number of drive pulses of the stepping motor 18. This mechanism also prevents the parallel moving lens CCD holding member 7 from colliding with the side wall surface or the like in the apparatus.

The terminal group 28 as the electrical connecting means of the film holding device is composed of a large number of electrical contacts. In the present embodiment, the following types of main output terminals are connected to the output lines.

28a, 28b ... 2-bit signal for determining the type of film holding device HL (: 10) ... Cartridge film holding device LH (: 01) ... 35 mm film holding device LL (: 00) ..・ No holding device 28c ・ ・ ・ Power supply line 28d ・ ・ ・ GND line 28e, 28f ・ ・ ・ 2-bit signal for film drive motor control HL (: 10) ・ ・ ・ Forward rotation LH (: 01) ・ ・ ・ Reverse rotation HH (: 11) ・ ・ ・ Brake LL (: 00) ・ ・ ・ Off 28g ・ ・ ・ PI / PR1 / PR2 LED power supply line 28h ・ ・ ・ PI output line 28i ・ ・ ・ PR1 output line.

The terminal group 28 composed of a large number of contacts listed above is arranged on the main substrate 17 as shown for electrical connection between the film image input device 1 and a film holding device 100 described later. When the film holding device 100 is mounted, the film holding device 100 and the film image input device 1 are interconnected by the terminal 28.

FIG. 3 shows, for example, 3 related to the device of the present invention.
The external appearance of the first embodiment of the film holding device 100 using a 5 mm film as an original is shown. Further, a slide film carrier 200 for holding a slide film 400 which can be engaged with the film holding device according to the present invention and a strip film carrier 250 for holding a strip film 450 are shown in a perspective view.

35 mm film holding device 100 of this example
Has an outer shape of the same shape as the groove portion 2 of the image capturing means 50 described above, and is formed so that it can be fitted and mounted in the groove portion 2.

On the side surface of the 35 mm film holding device 100, positioning pins (not shown) present on the side of the film image input device 1 when fitted in the groove portion 2 are fitted in the concave portions 101 and 102, respectively. "Positioning" for the body as the adapter in the plane perpendicular to the optical axis
Is completed.

Also, this 35 mm film holding device 100

28z) a metal pin 107 that is biased by a leaf spring
Is attached.

Further, 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 differ. For that purpose, a storage means such as an EEPROM (not shown) for storing the screen position of the film as the number of drive pulses from the reference position of the lens CCD holding member 7 is provided. This storage means is usually the film holding device 10 as an "adapter".
Since it stores information peculiar to 0, it is provided in the film holding device. The recorded contents are transmitted to the film image input device via the terminal 28, and the timing control of the start of capturing the screen data of the film and the personal computer (not shown below)
It is used for timing control and the like regarding data transfer to

The 35 mm film holding device 10
No. 0 is provided with a slit 103 in the upper opening for selectively mounting either the slide film carrier 200 or the strip film carrier 250 as desired by the user.

A pin 104 for "positioning" the carrier is supported by a leaf spring 105 so as to be able to move forward and backward. The recesses 203 and 257 of these two types of carriers are holes into which the positioning pins 104 are inserted.

In the explanation of the 35 mm film holding device 100 illustrated here, for comparison with a cartridge film holding device 300 of FIG. 4 described later, no film driving means for moving the film is particularly provided. This is because the film itself is driven by manually moving the dedicated film carrier, which makes it possible to make the film holding device 100 itself at a lower cost.

Further, if a film drive means, a film drive amount detection means and the like provided in the cartridge film holding device 300, which will be described in detail later, are added in the same manner,
It goes without saying that film can be fed "automatically".

The film holding device shown in FIG. 4 is a cartridge film holding device 300 which is a holding device of the first embodiment exclusively for holding the cartridge film 404 as a film, and its internal structure is seen through. It is shown in a perspective view.

The cartridge accommodating chamber 301 into which the cartridge film 404 is inserted is provided with a lid 302 that can be opened and closed in the direction of the arrow as shown. In addition, this lid 3
The lock mechanism 340 for locking 02 is configured such that the lid 302 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,
Since the switch is turned on / off according to the opening / closing of the lid, the operator can perform the “autoload” operation of the film by manually closing the lid 302, or the “rewind” of the film by manually opening the lid. The operation can be triggered automatically.

In the opening 303 for illumination, the screen of the film fed to this opening position is optically read by the film image input device 1 (not shown). On the side surface of the cartridge film holding device 300, positioning pins (not shown) on the film image input device 1 side are fitted into the recesses 304 and 305, respectively, when the cartridge film holding device 300 is mounted in the groove 2 on the image input device 1 side. "Positioning" takes place in a vertical plane.

Also, on the bottom surface of the cartridge film holding device 300, when it is mounted in the groove portion 2, a terminal 2 composed of a large number of electric contacts on the side of the film image input device 1 is formed.
8, a plurality of metal pins 407 that are biased by a leaf spring
Is attached.

Cartridge film holding device 30 of this example
0 receives a power supply for the film holding device and a predetermined control signal for driving the film from the film image input device 1 via these electrical contacts, and scans a desired film surface of the cartridge film. .

On the contrary, the film image input device sends, for example, "film drive amount information" sent from the cartridge film holding device 300 via the terminal group 28.
"Film information", "Film cartridge information",
It is also possible to receive "EEPROM information in the cartridge" or "SW information" attached to the cartridge.

Cartridge film holding device 30 of this example
At 0, a take-up spool 309 for taking up the film drawn out from the loaded cartridge is arranged on the opposite side of the cartridge storage chamber 301, and the spool 30
"Rolling" and "Rewinding" the film at the center of rotation of 9
A motor 308 that supplies a driving force for performing

A gear 311 fixed to the shaft and a plurality of gears 312, 313 and 314 mesh with each other on the output shaft of the motor 308, and the rotational driving force of the motor is generated through these gear groups. It is transmitted to the gear portion 310 fixed to the lower portion of the spool 309.

On the other hand, in the vicinity of the center of the lower part of the cartridge storage chamber 301, a gear forming a "gear connection" with the gear group is engaged in order to engage with the spool forming the central axis of the cartridge and rotate the spool. The drive shaft 324 is arranged. That is, the drive shaft 324 is connected to the gear 3
It is indirectly connected to the above-mentioned motor 308 through a gear 322 which is integrally fixed to and meshes with 23.

Further, as shown in the figure, in order to detect the driving amount of the film, a rod-shaped film driven roller 408 extended in a direction perpendicular to the running direction of the film is disposed in contact with the film, and is used for running the film. Rotate with it.
A disk-shaped member 409 called a “PI (Photo Interrupter) gear” having a slit of a predetermined pattern in the radial direction is attached to this end portion.
As the gear 409 rotates, the PI 410 as a photo sensor arranged so as to sandwich the PI gear,
Repeat the detection of "shading" / "non-shading".

Therefore, by counting the waveform pulse output from the PI, the running amount of the film can be detected. That is, at a position corresponding to a predetermined portion of the film, a PR (Photo Ref) for detecting a film perforation hole is detected in order to detect the driving amount of the film traveling.
1) is arranged as shown in the drawing, and sequentially detects the film screen position reference.

Further, a film cartridge information detecting PR 412 for detecting the information written on the film cartridge is arranged facing the bottom surface of the cartridge.

A magnetic head 413 for detecting magnetic information of the film is provided at a position facing the magnetic data area of the film (details, see FIG. 6C), and the recorded data is read. There is.

The motor 308 and various sensor groups (410, 411, 413) are connected to the electrical contact group 407 by a flexible printed board (not shown).

The circuit diagram shown in FIG. 5 is the same as the internal circuit diagram of the cartridge film holding device 100 shown in FIG.
It is an internal circuit diagram of the film image input device 1 illustrated in FIG. 2 as an example of an embodiment.

On the film image input device 1 side, a fluorescent lamp 3
An inverter circuit for lighting up and controlling the light amount, a CCD 9 for converting a film image into an electric signal, an image processing circuit block 55 including a clamp circuit, a gamma (γ) conversion type AD converter and the like, and a stepping motor for driving them stepwise. M is the RISC (Re
duced instruction set computer) 30.

Further, an EEPROM for storing information peculiar to the film image input apparatus 1 is connected. Also,
This data communication connector 22 with the PC is an IC dedicated for communication
It is directly connected to the RISC 30 without going through. The data communication with the PC is configured to be performed by the RISC communication software.

Here, if the above control is to be executed by software by a single controller, C
CD9 read sequence, image processing circuit block 55
The control sequence, the stepping motor M drive sequence, and the data communication sequence with the PC are processing sequences that require extremely high speed, and a plurality of sequences overlap each other in time. Therefore, each of the above sequences will be processed by conventional CP.
It is practically difficult to execute it by software using U.

Therefore, in the embodiment of the present invention,
The CISC (Comp
A single controller has been achieved by using a RISC (Reduced Instruction Set Computer) instead of a lexed Instruction Set Computer.

In other words, the CISC requires 4 clocks to execute one instruction, but the RISC can process in 1 clock. Therefore, the calculation can be performed at a speed four times higher than that of the CISC.

As a result, if it is assumed that the signal arithmetic processing of 30 steps of CISC is possible during the waiting time of each signal control processing, the RI adopted in the device of the present invention.
With the SC, it is possible to perform signal calculation processing in 120 steps, and it is possible to perform more sophisticated and complex signal calculation and control processing, and it is possible to improve S / N. In addition,
It would also be possible to perform more complex sequence control based on the given software.

On the film holding device 300 side as an adapter for the main body, a magnetic reproducing circuit block, an EEPR
A detection circuit block having sensors such as OM, (for detecting the running distance of the film) PI / (for detecting the film disc) PR1 / (for detecting the perforation) PR2, and a motor drive circuit block are arranged.

EEPR of the film holding device 300 side
The OM stores unique information about the film holding device such as a "rewind end flag" of the film cartridge, a "number of winding frames" and a "focus adjustment value" of the film.

For example, obtained by the above-mentioned sensor group,
The output pulse of the PI detection circuit represents the amount of film travel, P
The output pulse of the R1 detection circuit is used to detect the information code of the film cartridge written on the film disc, and the output pulse of one PR2 detection circuit is used to detect the perforation hole of the film. That is, it is used in a determination step of a control program, which will be described later, for recognizing a position associated with the traveling of the film and controlling timing of various operations.

Reproduction output terminal of the magnetic reproduction circuit block, P

D lighting control terminal, data communication terminal of EEPROM, control terminal of motor drive circuit block for film drive,
The SW output terminal and the power supply / GND input terminal are connected to the RISC 30 in the film image input apparatus 1 via respective dedicated connection terminals.

Further, in this example, since each output of PR1 / PR2 / PI is weak and weak against noise, the circuit configuration is such that dedicated buffers (indicated by triangles in the figure) are added to each of the terminals 28i to 28h to the RISC 30. Is output to.
As these buffers, for example, an inverter, an operational amplifier, a comparator or the like can be used.

The film holding device 100 exemplified above.
(300) is mutually connected to the RISC which is a control means inside the film image input apparatus 1 through the connection means 28, and each functional block of the film holding apparatus and the film image input apparatus is a scanning unit. It is configured so that it can be centrally managed under the control of the RISC on the apparatus body side.

Therefore, with the above-mentioned structure, the number of parts of the film holding device as the "adapter" can be reduced, and the mounting area and the manufacturing cost can be reduced and the size can be reduced. Also, with the unification of the control management of each timing, the software (program) is simplified as described below, thus contributing to the improvement of the reliability of the scanner device.

FIG. 6A is a flow chart showing the procedure for the "single frame feed process" routine, and FIG.
(C) illustrates a positional relationship between the pulse signal of the PR2 for perforation hole detection and the film when the control based on the procedure of (a) is performed.

According to the flow chart of FIG. 6A, the following series of processing steps are executed each time the frame on the film is advanced one by one. That is, "one frame feed processing"
When (S100) is called, the output state of the PA port of FIG. 5 is set to PA0 = H (High: 1) and PA1 = L (Low: 0), and the motor for driving the film is normally rotated (S101).

The occurrence of the "falling" state is determined by the pulse signal of the perforation hole detecting PR2, and if it has fallen, the process proceeds to step S103. If "it does not fall", the same step S102 is repeated (S1).
02).

At the "falling" of the pulse signal of PR2, since the magnetic head 80 is located at the beginning of the magnetic data area on the film, the recorded contents are read by calling the "magnetic data reproduction signal processing" routine (S10).
3).

Next, the output state of the PA port in FIG.
After 0 = H and PA1 = H, a short brake is applied to the driving motor, and then the motor is stopped to stop the film feeding (S104). Then, after a predetermined period (for example, 100 msec), the output state of the PA port is set to PA.
The motor drive circuit is turned off by setting 0 = L and PA1 = L.

By executing a predetermined "parity check", it is judged whether or not the reproduced magnetic data has been correctly read (S105), and if correct, the data is stored in the EEPROM in the following step S106. To do. On the other hand, if the reproduced data is not correct,
The data is discarded, and RET (return) is performed as it is from step S107 which is the exit of this routine.

FIG. 7 is a flow chart showing the detailed procedure of the above-mentioned "magnetic data reproduction signal processing" routine. This magnetic data reproduction signal processing routine S500 is Ca
First, the threshold level of the magnetic data of threshold (hereinafter referred to as TH) is set to a predetermined value (TH1, TH2, TH3). Also, PI
Reset the counter. Initial values are set for the storage array variables D (I), SD (I), DD (I), etc. of AD conversion values. Turn off the RET flag. Perform initialization processing such as. (Note that each initial value is stored in advance in the EEPROM.) (S501).

Next, PI, PR1, PR as sensors
Make settings to allow "interruption" from 2 (S
502). Initialize counter value I = 0 (S50
3).

AD of magnetic waveform data (FIGS. 9A to 9C described later) input from the terminal AD0 of the RISC shown in FIG.
The converted value is input to the array D (I) (S504). SD
Substituting the average value of N0 data of D (I) into (I),
The arithmetic processing indicated by the formula is performed (S505). By this processing, smooth magnetic waveform data subjected to the low-pass filter calculation (see FIG. 9B) can be obtained.

Subsequently, the difference of the data "smoothed" in the above step is substituted into DD (I), and a predetermined differentiating process shown in the equation is performed (S506). Comparing the smoothed data SD (I) with the threshold level TH1,
It is determined whether the data is near this peak (S5).
07). If this value is less than or equal to TH1, step S50
8, and if TH1 or more, step S509
Proceed to.

In step S508, DD (I) is compared with TH2. If the data is less than TH2, that is, near the peak, the absolute value of the difference data is smaller than TH3 in the next step. It is determined whether it is the peak of the converted data (S509).

If it is a peak in step S509, the PI count value at that time and
So-called "magnetic flag" information having two directions as shown by the arrow in (d) is stored as binary information in a predetermined storage means (for example, EEPROM) (S51).
0).

On the other hand, if it is not the peak here, the counter value I is incremented by 1 (S511), and then it is checked whether or not this I has reached the predetermined memory number (N0) (S512). While the number is equal to or less than N0, the process returns to step S504 and the same processing step (S50
4 to S512) are repeated.

On the other hand, when the counter value I has reached the predetermined number N0, it is determined whether or not the RET flag is turned on (ON). Returning to step S504, the same processing steps are repeated.

On the other hand, here, this RET flag is already ON.
If so, the routine returns to the routine called in the subsequent step S514, and the series of processes relating to "magnetic data reproduction" in the magnetic data area is terminated.

In FIGS. 8 (a) and 8 (b) shown below, as "interrupt processing", "PI" generated in response to film drive is generated.
The “interruption process” and the “PR interrupt process” are described in the flowchart.

When the PI as a sensor generates an "interrupt pulse" in response to the driving of the film, FIG.
PI interrupt processing routine (S60)
The execution right is transferred to 0). Since the generation of one pulse means that the film has traveled a predetermined amount, the PI counter (for counting the number of frames, for example) is incremented by one (S601).

Then, from step S602, the process returns to the step when the interrupt occurs. Further, when the PR as the sensor generates an "interrupt pulse" in response to the driving of one frame film, the execution right is transferred to the PR interrupt processing routine (S700) as shown in FIG. 8B. Then, the RET flag is set to ON in order to end the above-mentioned "magnetic data reproduction signal processing" (S7).
01).

Then, the process returns from step S702 to the step when the interrupt is generated. By the series of processing steps described above, the magnetic flag, the positional relationship on the film (PI count number), etc. are stored in the memory such as the EEPROM, and the processing routine (not shown)
Decoded.

Further, by adopting RISC as the control means, it becomes possible to perform high-speed processing of complicated processing operations such as signal smoothing processing, differentiation processing, window processing, etc., and there is much noise during the film winding processing.
