Contact glass 3 that forms a guideway for photography between it and 2
00, a white reference plate 323 for shading correction provided below the contact glass 300, and reading means for reading a photograph, for example, the carriage 301.
And elevating means 302 for elevating the carriage 301 along a substantially vertical contact glass 300.

The input device 3 as the second unit has the above-described configuration, and each component is disposed in one casing for the input device 3 and, as described above, the transport unit as the first unit. An assembly operation is performed separately from the device 2. Therefore, workability at the time of assembly and workability at the time of maintenance can be similarly improved.

The method of reading a photograph by the input device 3 is as follows.
There are types. One is paper feed tray 10 or manual feed tray 1
3 from the conveying means 12 and the contact glass 300
A reading position (reference position T1), and reading while moving a carriage 301 as reading means.
The other is to fix the carriage 301 at the reading position T2,
This is a method of reading a photo from the manual feed tray 13 while transporting the same. It should be noted that a method in which a photograph is fixed and reading is performed while moving the carriage (reading means) 300 is easier to obtain high image quality because the photograph does not vibrate.

As shown in FIG. 1, the carriage 301 moves the home position H and the reading position T
2 can be freely moved up and down along the contact glass 300.

Here, the home position H is a position where the carriage 301 is held when the apparatus is not operated. As will be described later, the carriage is provided with a plurality of components for reading photographs, such as a light source and a lens unit. Therefore, the weight is relatively large. Therefore, when the apparatus is not operated, the carriage 301 is held at a position lower than the center position M of the platen glass located substantially at the center in the height direction of the apparatus (that is, the center position of the apparatus), so that the center of gravity of the entire apparatus is maintained. And the stability of the device can be improved. Therefore, in this embodiment, the lowest position in the operation range of the carriage is set as the home position H, so that further stability can be obtained.

As shown in FIG. 2, the carriage 301 includes a light source 303 such as a xenon lamp for irradiating a photograph with light,
A plurality of mirrors 304, 305, 306, and 307 that reflect light reflected from a light source cable 303K and a photograph, and a lens unit 30 that forms an image of the reflected light from the mirror 307
8, a color image sensor 309 such as a CCD for photoelectrically converting the formed reflected light, and an image sensor 309.
Sensor board 325 with signal attached thereto and signal cable 32
5K and an integral unit.

As shown in FIG. 24, the carriage 301 has upper and lower frames 331 and 33 provided at both ends.
2 supported by a pair of guide shafts 333, 334
Are supported by a supporting member 503 so as to be vertically movable. Here, the support member 503 is made of a cylindrical polymer material, and the inner diameter of the cylinder is the guide shafts 333, 33.
4 is formed so as to be equal to the diameter of the carriage 301. However, since there is a slight error in the diameter of the two, slight rattling (vibration) occurs when the carriage 301 moves.
This rattling is greater when the carriage 301 descends than when it rises. Therefore, as described later, when reading while fixing the photograph and moving the carriage 301, it is sufficiently possible to perform reading while lowering the carriage 301. In order to further reduce the influence on the image quality due to the rattling, the reading is performed while moving upward.

An A / D converter 326 is provided on the sensor substrate 325 as shown in FIG. The light source 303 is turned on by the inverter 327.

An impact absorbing member 335 is provided on the lower end surface of the carriage 301, and the carriage 30
Even if 1 passes through the home position H and collides with the lower frame 332, the impact can be absorbed.

The home position sensor 330 of the carriage 301 is provided on the lower frame 332.

On the other hand, as shown in FIG. 3, the driving force of the carriage motor 310 is controlled by the pulley 311 and the timing belt 31.
2, transmitted to the rotating shaft 313 via the pulley 314.
Further, the power is transmitted from the rotating shaft 313 to the rotating shaft 317 via the pulley 315 and the timing belt 316.

A pulley 319 is attached to the rotating shaft 317, and a timing belt 321 is stretched between the pulley 320 and a pulley 320 provided below.
A carriage 301 (not shown) is connected to one transfer device 2 side (the left side in FIG. 3) by a connecting member 322. Therefore, the driving force of the motor 310 is transmitted to the rotating shaft 317,
When the rotation shaft 317 (and the pulley 319) is driven and rotated, the timing belt 321 is rotated, and the carriage 301 is moved up and down. Then, as shown in FIG. 3, when the rotation shaft 317 is driven to rotate clockwise, tension is generated on the left side of the timing belt 321, and the carriage 301 can be moved up more stably, and a photograph described later is fixed. And carriage 30
In the case of reading while moving 1, the influence on the image due to the movement of the carriage 301 at the time of reading is further reduced.

As described above, by arranging the contact glass and the transport means substantially perpendicular to the installation surface of the apparatus, the installation surface of the apparatus can be reduced, and the reading means can be moved up and down along the contact glass. In this manner, reading is performed while the fixed and attached photograph is moved up or down. Further, the operability is improved by arranging the paper feed tray and the paper discharge tray on the same side of the apparatus and substantially in parallel with the installation surface. Further, in the case of fixing and reading a photograph which easily obtains high image quality, the image quality is further improved.

The reading means may be of a type in which the light source unit and the mirror unit move at a speed of 2: 1 and perform photoelectric conversion by an image sensor fixed or a photoelectric conversion by a contact image sensor. That is, it suffices that at least a part of the reading means performs reading while moving up or down the predetermined area. Also,
Also in these cases, the home position is preferably provided below the center position of the contact glass. 1-3 (Control Means) As shown in FIG.
00 is provided. The control board 400 includes a CPU
401, SRAM 402 for line correction, SRAM 403 for shading correction, SRAM 40 for gamma correction
4, a transmission buffer SDRAM, an image data processing IC 406, a transfer data processing IC 407, and a ROM
408, SRAM 409, EEPROM 410,

Interface 413 and is connected to an AC power supply.

The CPU 401 executes the program stored in the ROM 408, drives the motors 100, 200, 274, 310, etc., based on information of various detection sensors, and conveys them.
Make a reading.

The inter-line correction SRAM 402 is used to correct the interval between the three pixel rows of RGB. Output data from the image sensor 309 in which each of the RGB pixel columns is configured to have a certain distance is a certain time t.
If the data of the first pixel column is set to the Nth line when 0, the second
The pixel column is on the (N−n) th line, and the third pixel column is on the (N−2n) th line. The function of temporarily storing past data and outputting data of the same line at the same timing is inter-line correction, which is a storage element for storing past data.

The shading correction SRAM 403 comprises:
When performing shading correction in order to remove the effects of non-uniform optical systems and sensitivity unevenness of the image sensor 309,
This is a storage element for storing reference black and reference white data for all pixels of each color of RGB required for correction.

The gamma correction SRAM 404 needs to perform gamma correction on image input data in order to correct the linearity of the color gradation of the obtained image data or to obtain an arbitrary output. This is a storage element for storing look-up table data at this time in order to convert data of ~ 4095 into arbitrary data using a look-up table.

The transmission buffer SDRAM 405 temporarily stores data to be transferred to the control device 430. The finally obtained data is transferred to the control device 430 via the SCSI-2 interface 412.
If the time required for data transfer is longer than the time required for data reading, the reading needs to be interrupted. Therefore, it is a storage element for temporarily storing output data so that data can be read without interruption during data transfer.

Image data processing IC (gate array) 4
Reference numeral 06 denotes an element dedicated to performing the above-described corrections and color correction for removing the influence of the optical system, the image sensor 309, and the like.

Transfer data processing IC (gate array) 4
Reference numeral 07 denotes a dedicated element that processes the processed data before transfer into a form suitable for transfer and controls the transmission buffer SDRAM 405.

The ROM 408 stores a program for controlling the entire apparatus.

An SRAM 409 is a storage element for temporarily storing operation data of the CPU 401.

The EEPROM 410 is a storage element for storing adjustment values of the optical sensor and the like.

The control device 430 is a computer, and executes a command for setting a type of a photograph, a command for starting reading, and a command for image processing. The control device 430 reads the photograph stopped at the first reading position T1 of the contact glass 300 by the transport unit 12 while raising the carriage 301, and the first reading mode along the contact glass 301 by the manual sheet feeding unit 14. The first reading position T
And a second reading mode for reading a photo moved at a second reading position T2 provided above the first while the carriage 301 is stopped, and for reading a photo on the paper feed tray 10 in the first reading mode. It has a function of executing a reading operation and executing one of the first reading mode and the second reading mode according to the type of a photo placed on the manual feed tray 13.

In the second mode for reading an image while transporting a photo, the image quality is reduced or the panorama size is read in comparison with the case where the photo is fixed and read as in the first mode. Due to the large amount of data, the second
Of the reading mode is lower than that of the first reading mode.

For example, in the first reading mode, 6
Reading is performed at a resolution of 00 DPI, and in the second reading mode, reading is performed at a resolution of 300 DPI. Also the second
The transport speed of the photo moving at the reading position T2 in the reading mode is the carriage 301 in the first reading mode.
Is twice as high as the reading speed. 2. Operation 2-1 (Automatic paper feed) Hereinafter, the operation in the automatic paper feed mode will be described with reference to FIGS.
33 and the timing charts of FIGS. 33 and 34. Note that the flowchart is a flow for processing one photo, and the timing chart is an example in a case where there are two photos. (Sheet Feeding Section 5) First, the lever 23 is rotated clockwise in FIG. 2, the sheet feeding tray 10 is lowered, and a plurality of photographs are set. Then, the lever 23 is rotated counterclockwise to press the photograph against the kick roller 149.

On the other hand, the automatic paper feed mode is selected by the control device 430 (step S1), and the start switch 7 is turned on (step S2). If the empty sensor 27 is on, the paper feed motor 100 rotates forward (step S3,
S4).

The rotation of the feed motor 100 causes the pulley 101, the timing belt 102, and the pulley 1 as shown in FIG.
The rotation shaft 104 is rotated forward through the shaft 03. As a result, the drive is transmitted to the gear 105W and the pulley 107, and the gear 14
The paper feed roller 145W and the pickup roller 149W rotate in the paper feed direction via the rollers 0 and 141. For this reason, the picture is paid out. Although the pulley 110W rotates by the rotation of the pulley 107, the one-way clutch is interposed in the pulley 110W, and the rotating shaft 111 does not rotate.

A plurality of photographs fed by the pickup roller 149W are fed to the paper feed roller 1 rotating in the paper feed direction.
The sheet is separated into one sheet by a non-rotating separation roller 146 with 45 W and fed out.

If the size of the photograph taken out is 4R, it is detected by the sensor 29 (step S5), and if not detected, it becomes another size.

The leading end of the separated photo is regulated by the pressure contact with the registration rollers 162 and 163, and the inclination of the photo in the transport direction is corrected. At this time, the photograph whose tip is regulated tends to bend, but since a torque limiter is interposed in the gear 141T, the rotating shaft 143 does not rotate when a load exceeding a predetermined level is applied.

By the way, the leading end of the separated photograph is detected by the registration sensor 30 before reaching the registration rollers 162 and 163 (step S6), and after a predetermined time, the motor 100 is stopped (step S7). (Conveyance Unit 5 / Discharge Unit 6) Thereafter, the conveyance / discharge motor 2 is used to convey the registered photo to the reading position T1.
00 is driven forward (step S8). Therefore, FIG.
The rotary shaft 242 rotates via the pulley 240, the belt 241, and the pulley 243 as shown in FIG.
The registration rollers 162 rotate via the 249 and 171W. Therefore, the photograph whose registration has been corrected is transported by the registration rollers 162 and 163. On the other hand, the stopper motor 274 is driven simultaneously with the driving of the transport / discharge motor 200. The leading end of the photograph sent out by the registration rollers 162 and 163 is detected by the sensor 31, and the sending time is counted (step S9). If the image is not determined to be a 4R size photograph by the sensor 29, the sensor 3
1 determines the size based on the feed time from when the leading edge of the photograph is detected to when the trailing edge is detected (step S10).

On the other hand, the pulley 246W idles by a one-way clutch provided on the pulley 246W attached to the rotating shaft 242, and the drive is not transmitted to the pulley 252W.

The driving force of the rotating shaft 242 is
5, 254, 255W, 272W via the rotation shaft 251
, The timing belt 211 rotates in the direction of transporting the photo downward, and transports the photo fed by the registration roller 162 along the contact glass 300.

The drive transmitted to the belt 211 is the pulley 21
3, 258, a belt 259, pulleys 260 and 261, a belt 262, and a pulley 264 to be transmitted to a rotating shaft 263.

The drive transmitted to the rotation shaft 263 is transmitted to the rotation shaft 233 via gears 269 and 270, and the discharge belt 228 and the discharge roller 234 rotate in the discharge direction, and the gear 265 and the belt 266 are rotated. The roller 225 rotates in the sheet discharging direction via the pulley 268.

On the other hand, as shown in FIG. 20, the sensor 282 is driven by the stopper motor
Upon detecting 81b, the motor 274 is stopped, and the stopper 273 contacts the contact glass 300, that is, the stopping means 214 is driven, the stopper 273 protrudes, is pressed against the contact glass 300, and the conveyed photograph is read at the reading position (reference position). (Position) Stop at T1. Then, the motor 200 stops (step S11). At this time, the photograph is fixed along the contact glass 300.

Then, the stopper motor 274 is driven,
As shown in FIG. 15, the sensor 282 is connected to the edge 2 of the light shielding plate 281.
Upon detecting 81a, the motor 274 is stopped. In this state, the stopper 273 is retracted from the contact glass 300 (Step S12). In addition, as shown in FIG. 33, the paper feed motor 100 is driven to rotate forward, and the next photograph is sent out in the same manner as described above (second paper feed). (Input device 3) After the stopper 273 retracts, the carriage 3
When the motor 310 is driven to rotate forward to read the image by raising 01 (step S13), the pulley 319 is driven via the pulley 311, the belt 312, the pulleys 314, 315, the belt 316, and the pulley 318, and the belt 32
1 is the home position H
Going up from.

First, the carriage 301 reads the white reference plate 323 for shading correction. Thereafter, the reading of the photograph fixed at the reading position (reference position) T1 along the contact glass is performed while ascending from the reference position T1,
The ascending movement (reading) range varies depending on the photograph size. When the reading is completed, the motor 310 is stopped (step S14), and the transport / discharge motor 200 and the carriage motor 310 are driven to rotate in the reverse direction (step S15). When the carriage 301 descends and the home position sensor 330 detects (step S16), the motor 310 stops.
(Step S17). (Sheet discharging unit 6) The conveyance / discharge motor 2 upon completion of reading
00 is reversely driven, the drive transmitted to the rotating shaft 242 drives the rotating shaft 251 via the pulley 246W, the belt 250, and the pulley 252W, and the belt 211, the belt 22
8, rotate the rollers 225 and 234 in the discharge direction,
The read photograph is discharged to the discharge tray 16. At that time,
When it is detected that the paper is discharged by the paper discharge sensor 235,
(Step S18), the transport / discharge motor 200 stops (Step S19).

Since the one-way clutch is attached to the gear 244W attached to the rotating shaft 242, the registration roller 162 does not rotate.

When the first copy sheet is discharged, the second copy sheet is conveyed as shown in FIG. 33, the photograph is stopped at the reading position T1 in the same manner as described above, and the image is read and discharged by the carriage 301. . 2-2 (Manual Paper Feeding) Hereinafter, the manual paper feeding mode will be described with reference to flowcharts of FIGS. 30 to 32 and timing charts of FIGS. 35 to 37. 2-2-1 (Panorama Photo) When a photo is set on the manual feed tray 13 (step S
1) The operator sets the panoramic photograph mode or the instant photograph mode by the control device 430 (step S)
30). When a photo is set on the manual feed tray 13, the photo is set to the left side.

The position of the discrimination sensor 137 is at a position where a panoramic photograph is not detected, and the instant photograph is detected by the discrimination sensor 137.

When the panorama photograph mode is selected and the start switch 7 is turned on (step S31), whether the empty sensor 136 of the manual feed tray 13 is on
It is checked whether a photo is set on the manual feed tray 13 (step S32). When the start switch 7 is turned on, if a photograph is set on the manual feed tray 13, the carriage motor 310 of the input device 3 is driven (step S33), and the carriage 301 is raised to the reading position T2 (step S34).

Further, although the paper feed motor 100 is driven to rotate in the reverse direction (step S35), the drive is not transmitted to the paper feed means 11 because the one-way clutch is interposed in the gear 105W. However, the gear 106W, the pulleys 107 and 108
The drive is transmitted to the manual paper feed unit 14 via the
12, belt 122, grid roller 134, roller 1
39 rotates in the paper feeding direction.

Further, the transport / discharge motor 200 is also driven to rotate in the reverse direction (step S35), and the transport belt 211 and the discharge belt 2
28, the roller 225 and the paper discharge roller 234 are rotated.

The panoramic photograph fed out by the manual paper feed means 14 is detected by the sensor 138, and is conveyed by a predetermined amount, and is stopped at the reading position T2 after being conveyed by a predetermined amount.
The image is conveyed downward while the image is read by 01 (step S37). When the sensor 138 detects the trailing edge of the photograph (step S38), the image sensor 309 after a predetermined time has elapsed.
The image reading is finished (step S39), and after driving by a predetermined amount, the sheet feeding motor 100 stops (step S40). Further, the carriage motor 310 rotates reversely (step S41).
The carriage 301 descends and the home position sensor 3
30 and stops (steps S42 and S43).

When the trailing edge of the photograph is detected by the paper discharge sensor 235 (step S44), the motor 200 stops (step S45). 2-2-2 (Instant Photo) First, with the photo set on the backing paper, the manual feed tray 13
Place on. Then, the controller 430 selects the instant photo mode (step S36).

There are a large size and a small size in the instant photograph, and both of them are conveyed while sandwiched between mounts. When the discriminating sensor 137 detects the mount, the size becomes large.

When the start switch 7 is turned on (step S50), it is checked whether or not the empty sensor 136 is on (step S51). It is determined whether the size is small (step S52). Further, the paper feed motor 100 is driven to rotate in the reverse direction, the manual paper feed means 14 is driven, the transport / discharge motor 200 is driven to rotate in the reverse direction, and the transport belt 211 and the paper discharge unit 6 are driven (step S53). Also, the stopper motor 274 is driven,
The stopper 273 protrudes.

The trailing end of the mount is detected by the sensor 138 (step S54), and the feed motor 100 stops after the driving amount of the trailing end passing through the roller 139 (step S55).

On the other hand, the stopper 273 is in contact with the contact glass 300 by the driving of the stopper motor 274, and when the mount is fed by a predetermined amount and conveyed by an amount hitting the stopper 273, the convey / discharge motor 200 stops (step S1). S56). Then, the stopper motor 274 is driven to retract the stopper 273 (step S57).

Next, the carriage motor 310 is driven.
(Step S58) The carriage 301 reads the image of the instant photograph while rising (Step S59). After increasing the distance according to the size while reading, the motor 310 is stopped. (Step S60). Thereafter, the motor 200 is rotated in the reverse direction to drive the transport belt 211 and the paper discharge unit 6 to discharge the mount, and the motor 310 is rotated in the reverse direction (step S61), and the carriage 301 is lowered to the home position H and moved to the home position. When detected by the sensor 330 (step S62), the carriage motor 31
0 is stopped (step S63). When the trailing end of the sheet being discharged is detected by the discharge sensor 235 (step S64), the transport / discharge motor 200 is stopped (step S65).

As described above, in the first reading mode in which the reading is performed by moving the reading means (carriage) while fixing the photograph, vibration due to the movement of the photograph does not occur, and a good image is easily obtained. In order to further reduce the influence on the image due to the vibration during the movement of the carriage, the reading is performed while the carriage is moved upward, and the rotation drive belt of the belt with which the carriage is engaged is stretched. Was driven to rotate. The reference position T is located near the lower end of the contact glass 300.
