A light source 103 such as a flash lamp held on a stand 104 is used to scan the original 1 on the original table.
This is done by illuminating the camera 105 and releasing the shutter of the camera 101 to take a picture.

Furthermore, the system described in Japanese Patent Application Laid-Open No. 63-274940 includes a first imaging optical system that guides the reflected light from the original to a first photosensitive film holding means, and a first imaging optical system that directs the reflected light from the original to the first photosensitive film holding means. A second imaging optical system that guides the light reflected from the original to a second photosensitive film holding means and a surface filling optical system that directs the reflected light from the original to the first photosensitive film holding means or the second photosensitive film holding means. Equipped with optical path selection means for guiding to either one.

Image forming apparatuses that do not require complicated operations such as focusing and adjusting the position of a light source have also been proposed.

FIG. 12 is a flowchart of the main routine.

When the main routine starts, the stack pointer is set in step (hereinafter abbreviated as S) 1, and S
At step 2, the RAM clear subroutine is called.Then, at step 83, the subroutine table pointer is set, and the subroutine table is searched (S4).

FIG. 13 is an explanatory diagram of the RAM space, and FIG. 14 is an explanatory diagram of the nonvolatile memory area thereof. R shown in Figure 13
The AM space addresses FFOOH to FFFFH are backed up by a battery when the device is powered off. FF0OH-FF of this RAM space
Address 2OH is used as a non-volatile memory area, and the
As shown in Figure 4, this area stores information such as perforation count, film sensitivity, film type, and operation mode. This part of the RAM will not be cleared when the device is turned on again, so turn the power off.
Data such as the number of perforations at F time, film sensitivity, film type, document size, and operation mode are held. Therefore, as described later, when the main routine calls the initial mode subroutine,
Film sensitivity, film type, and document size are automatically set to the data before the power was turned off. Addresses FF20H to FFFDH in the RAM space are used as an operation area for storing, for example, input/output signals of various sensors, presence/absence of flags, and the like.

FIG. 15 is a flowchart of the RAM clear subroutine. As shown in the figure, at 85, address F
The part F02H-FFFDH (operation area) is cleared.

FIG. 16 is an explanatory diagram of the subroutine table. As shown in the figure, this table shows the initial mode,
Wait mode, print mode, rewind mode,
It has subroutines such as prewind mode and abnormal mode.

FIG. 17 is a flowchart of the CPU initialization subroutine in the initialization mode. With the start of this subroutine, the boat input/output mode is set in S6, and the port output is turned OFF in S7.
Next, in step 88, a timer for 2 m seconds is set, and in step S9, the data in the non-volatile memory is loaded into the RAM of FF 20H.

FIG. 18 is a flowchart of the 5-machine initialization wait mode shift subroutine. At the start of the subroutine, it is confirmed in S10 that 100 msec has elapsed, and then it is determined in Sll whether or not it is the pack mode for projecting onto a pack film.

If it is the pack mode, the process proceeds to S12, and if the document size is 8.5 inches x 11 inches, the process proceeds to S13 to set the size display for that document.

S14 with 8.5X lens turret for pack film
Set the motor flag to move to the 11 side. If NO is determined in S12, the document size display of 5 inches is set in 815, and the process further proceeds to S16, where a motor flag is set to move the pack film lens turret to the 5×7 side.

If it is determined No in the Sll, it is determined in S17 whether the document size is 8.5 inches x 11 inches, and if YES, the display of that size is set in S18, and in S19
Proceed to 8.5X1 lens turret for pack film.
At the same time, set the motor flag to move the roll film lens turret to the 8.5X11 side. If NO is determined in S17, the size display of 5 inches is set in S20, and the process proceeds to S21, where the roll lens turret is set to 5×.
A motor flag is set for moving to the 7 side.

After the motor flag is set in this way, the display of the previous film sensitivity (ISO) is set in S22, and the wait mode subroutine is called in S23. The steps 811 to 522 described above are performed according to the data stored in the nonvolatile memory.

FIG. 19 is a flowchart of the initialize mode head return subroutine, in which the process of returning to the initial mode is performed in S24.

In the image forming apparatus according to this embodiment, the film sensitivity (rso) is 1.12°40.100, as shown in the following table.
Six types of roll film, 125 and 400, can be used, and in the case of pack film, one with a film sensitivity (ISO) of 80 can be used. The ISO selection is sequentially changed by pressing the ISO key 12 shown in FIG.

Further, as shown in the table, the amount of flash light is changed depending on the ISO, and fine adjustment of the amount of light emission is made by the amount of light emission adjustment volume 11 shown in FIG.

In addition, in this table, the first light emission mode, the second light emission mode,
The intensity of the light quantity becomes weaker in the order of the third light emission mode and the fourth light emission mode.

In the subroutines shown in FIG. 20, FIG. 21, and FIG.
A check is made on the data before F to see if there has been a change in ISO, film type, or document size.

FIG. 20 is a flowchart of the ISO specification subroutine for photosensitive film. When this subroutine starts, it is determined whether it is a roll film or not in step 524. If the photosensitive film set is a pack film, the ISO is determined to be 80 as mentioned above, so there is no need to go through this routine. will be reset.

If the photosensitive film set is a roll film, when it is confirmed in S25 that the ISO key has been pressed, the process advances to 826 and it is determined whether or not the previous ISO stored in the non-volatile memory area was 40. If so, 8
27, skips to the next ISO, and sets the display of 150100.

If it is determined No in S26, the process proceeds to 828, where it is determined whether or not the previous ISO stored in the non-volatile memory area was 400. If so, the process returns and the display of 15OI is set in 829, and 828 If the determination is NO, the next ISO display is set in S30.

In this way, the ISO change check is 15OI → 15O
I2→I SO40→ISO1004ISO125→I
The process is repeated in the order of 80400→IS○1...

FIG. 21 is a flowchart of the film designation subroutine. When this subroutine starts, S31
It is determined whether or not the film select key has been pressed, and if the film selection key has not been pressed (NO), it is determined that there is no change in the film and the film is reset.

If the film select key is pressed, proceed to S32;
A film change flag is set for the motor control mode designation subroutine to be described later.

Next, in S33, it is determined whether or not a pack film was used before, and if a pack film was used previously and the film has been changed this time, a roll film display is set in S34; Using film (
That is, N in S33.

If there is a film change this time, the pack film display is set in S35.

FIG. 22 is a flowchart of the document size designation subroutine. When this subroutine starts, 836
It is determined whether the document size sensor is pressed or not, and the third
As shown in the figure, if the document size sensor 6 is on, the document size is 5 inches, so S3
If the display is set to 5x7 size in 7 and the document size sensor 6 is not turned on, the display is set to 8.5x1 in 838.
A display set of one size is created.

Then, for the motor control mode specification subroutine to be described later, it is determined in S39 whether or not the document size has changed during one cycle of this routine, and if the document size has changed, the document size change flag is turned on in S40. do.

FIG. 23 is a flowchart of the pack shutter initialization subroutine. This subroutine is a flow that corresponds to when the main switch is accidentally turned off while the shutter is open and exposed in pack mode.
As mentioned above, if the main switch is turned off with the shutter open, exposure will continue, so the shutter must be closed.

When this routine starts, it is determined in 841 whether or not the copy mode is in effect, and if it is in the copy mode, there is a possibility that the shutter is open.

In S42, the pack shutter motor is driven for a certain period of time. If the shutter motor is driven for a certain period of time with the pack shutter open, the shutter will close, but the main switch may be turned off before the shutter opens.

Therefore, it is determined in S42 whether or not the shutter sensor is on, and if the sensor is on, that is, if the shutter is open, the pack shutter motor is driven again to ensure that the shutter is closed.

FIG. 24 is a flowchart of the roll shutter oven subroutine. When this routine starts, it is determined in 845 whether or not the strobe switch is on, and if the strobe switch is on, it is determined in step S45.
The roll shutter motor is set to 0FFL, and the roll shutter flag is reset at S47.

FIG. 25 is a flowchart of the abnormality detection subroutine. When this routine starts, it is checked in 848 whether the roll turrets for roll film and pack film are operating normally or not, in S49 whether the roll shutter is operating normally or not, and in S50 whether the rear curtain magnet is operating normally or not. In S51, check whether the film winding operation is normal or not.
2, whether the flash lamp is operating normally or not, 85
In step 3, it is determined whether the pack shutter operates normally, in step S54, it is determined whether the second mirror operates normally, and in step S55, it is determined whether the exterior cover is closed, and if the determination at each step is NO, then At S56, the program goes to the abnormal mode subroutine.

FIG. 26 is a flowchart of a blue routine for displaying the number of films. When this routine starts, it is determined in 357 whether or not the prewind mode is set, and in S58 it is determined whether or not the rewind mode is set. If it is not in either mode, the process advances to S59 and the set photosensitive film is It is determined whether it is a roll film or not. If it is not a roll film, that is, if it is a pack film, the number of films set is fixed to 1, so 1
There is no need to display the number of sheets, and the process advances to S60 to set the display off.

86 when it is determined that a roll film is set.
1, it is determined whether the print mode is selected. If copying is in progress, the number of flushes is set in S62.

If it is determined that the prewind mode is set in S57, or if it is determined that the rewind mode is set in 358, or if it is determined that the print mode is not set in S61.

In other words, with the film partially wound, S63
Then, the number of films is calculated.

FIG. 51 shows a state in which rewinding has been completed. Usually, a large number of perforations 80 are formed on both sides of the roll film 79 along the longitudinal direction of the roll film 79.
The length of eight perforations corresponds to one frame of film photography. (Counting of phorations is performed by a perforation counter that includes an optical sensor that includes a light emitting element and a light receiving element, and a counter that counts signals from the sensor. In addition, 81 in the figure is a cartridge. .

Returning to FIG. 26 again, the formula (n/8)-3 is used to calculate the number of films in S63.

In the formula, n is the perforation count, and 3 is the number of unused portions at the leading edge of the film. Once the number of films is calculated in this way, the number of films is set in S64.

FIG. 27 is a flowchart of the motor control mode command subroutine. When this subroutine starts, it is determined in S65 whether or not the document size has been changed. This determination is made based on whether the flag is set at 840 in FIG. 23.

If there is a change in the original size, it is determined in S66 whether the original size is 5 inches or not, and if that is the case, the process proceeds to 867 and it is determined whether the set photosensitive film is a pack film or not. . If it is a pack film, it is 868 and the lens turret for pack film is 5X.
Set the motor flag to move to the 7 side. Also, if the film set is a roll film, the S
Step 69 sets the motor flag for moving the roll film lens turret to the 5x7 side.

If it is determined in S66 that the document size is not 5x7, it is determined in S70 whether the photosensitive film set is a pack film or not. 8
, sets a motor flag to move the roll film lens turret to the 3.5X11 side, and sets a motor flag to move the roll film lens turret to the 3.5X11 side in S72 if it is not a roll film.

If it is determined in S65 that there is no change in the document size,
Proceeding to S73, it is determined whether or not the film has been changed. This determination is made based on whether the flag is set in S32 of FIG. 21.

If there is a change in film, it is determined in S74 whether the document size is 5 inches or less, and if that is the size, the process proceeds to 875 and it is determined whether or not it is a packed film.

As a result of this judgment, if it is a pack film, the second
Retract the mirror from the optical path and set the motor flag to move the pack film lens turret to the 5X7 side. If it is a roll film, the pack film lens turret is moved to the 8.5x11 side in S77, the second mirror is inserted into the optical path, and a motor flag is set to move the roll film turret to the 5x7 side.

Further, if it is determined NO in S74, it is determined in S78 whether or not it is a packed film.If the result of the 0 determination is that it is a packed film, the second mirror is retracted from the optical path in S79, and the lens turret for packed film is removed. 8.5X11
Set the motor flag to move to the side. If it is a roll film, insert the second mirror into the optical path at S80 and set the roll film lens turret to 3.5X11.
Set the motor flag to move to the side.

FIG. 28 is a flowchart of the mirror motor/lens turret motor control subroutine. When this subroutine starts, it is determined in S81 whether a flag for retracting the second mirror from the optical path is set, and if the flag is ON, the second mirror is retracted from the optical path in S82.

If the flag is not set in S81, it is determined in S83 whether the flag for moving the pack film lens turret to the 8.5X11 side is set, and the flag is set to O.
If N, move the pack film lens turret to the 8.5X11 side in S84.

If No in S83, it is determined in S85 whether a flag for moving the lens turret for pack film to the 5×7 side is set, and if the flag is ON, the lens turret for pack film is moved to the 5×7 side in S86. If the answer is No in S85, it is determined in S87 whether or not a flag for moving the roll film lens turret to the 5×7 side is set, and if the flag is ON, S88
Move the roll film lens turret to the 5x7 side.

If No in S87, it is determined whether a flag for moving the lens turret for roll film to the 8.5X11 side is set (S89), and if the flag is ON, in S90, the lens turret for roll film is moved to the 8.5X11 side. .5X

FIG. 28 is a flow chart of the pre-winding mode subroutine. When this subroutine starts, S8
At step 9, it is determined whether the camera back cover, which is an opening/closing means for attaching and detaching a photosensitive film, is opened or closed. This judgment is made based on the presence or absence of a signal from the back cover sensor 61 shown in FIG. If the back cover is open, S90 determines whether the back cover is upright.
If the flag is NO, it is determined in S91 that the roll shutter brake is OFF, the roll shutter motor is turned ON in S94, and the trailing curtain magnet is turned ON in S94 so that the shutter is in the open state. . In S95, a flag indicating that the roll shutter motor is rotating is set, and in S96, an abnormality detection timer is started to detect an abnormality in the shutter motor.

The roll shutter motor continues to be turned ON until it is determined that the strobe SW has started at step S in the flow of the roll shutter open subroutine shown in FIG.
The roll shutter flag is reset at 5315.

If the camera back cover remains open, the back cover flag remains set in S90, and the shutter remains open. When the camera back cover is closed, NO is determined in step 889, and it is determined in step S97 whether or not the roll shutter flag is set. When the flag is ON, the roll shutter motor is rotating, so the process returns as is. When the flag is No. 5309, set the trailing curtain magnet to 0FFL, close the roll shutter, and
310 to determine whether the camera back flag is set.

If the flag is set to determine whether the camera back has been opened/closed or continues to be closed, this means that there has been an opening/closing operation, so reset the camera back flag in step 5311 and return to step 53.
At step 12, a transition is made to the pre-rewind mode.

Although not explained here, if a problem occurs due to the camera back being left open for a long period of time, a timer will set the timer to allow a certain amount of time to elapse after the shutter is opened. Afterwards, the shutter may be closed.

In the above embodiment, the first photosensitive film holding means and the second photosensitive film holding means are
Although an example has been shown in which different types of film, namely a roll film and a pack film, are respectively set in the photosensitive film holding means, the same type of photosensitive film may be set respectively.

In the embodiment described above, the first imaging optical system and the second imaging optical system are connected by fixing the first mirror and inserting or retracting the second mirror into the reflected optical path from the first mirror. However, the present invention is not limited to this; for example, by making a reflecting mirror such as the first mirror rotatable, and by the rotational movement, the first imaging optical system and the second imaging optical system are switched. The optical path of the optical system may be switched.

In the above embodiment, a case where two types of original sizes can be used has been described, but it is also possible to read image information from originals of various sizes by using a lens whose focal length can be changed, such as a zoom lens or a conversion lens. can.

As in the above embodiment, the document size detection means has a reference position regulating section such as a document size switching lever that is movable depending on the document size, and the document position on the document table is regulated by this reference position regulating section. If so, the projection position of the original image on the photosensitive film can be ensured appropriately (for example, at the center of the photosensitive film).

Furthermore, as in the above embodiment, when a lens exchange means having a plurality of lenses with different lens barrel lengths is arranged behind the reflecting mirror, after the reflecting mirror is retracted from the optical path, the lens exchange means re-lenses the lens. If the lens of the longer tube is configured to move onto the optical path, it is possible to bring the reflecting mirror and the lens exchange means as close as possible, which allows the device to be made more compact.

Furthermore, as in the above embodiment, when a lens exchange means having a plurality of lenses with different lengths of lens barrels is arranged behind the reflecting mirror, when a lens with a short lens barrel length is selected, five reflections occur. If the mirror is allowed to be inserted into the optical path.

The reflecting mirror and the lens changing means can be brought as close together as possible, which allows the device to be downsized.

[Effects of the Invention] Since the present invention has the above-described configuration, when the photosensitive film attachment/detachment opening/closing means is opened when replacing the photosensitive film, the shutter means is in an open state, so that the shutter means is in an open state. etc. do not touch the shutter, and damage to the shutter can be prevented. This makes it possible to avoid parts replacement costs and lost time due to shutter damage.

In addition, when the opening/closing means for attaching and detaching the photosensitive film is opened,
By opening the shutter means, there is a possibility that dust, etc. will fall onto the lens, but as long as the dust is small, it will have little effect on the image, and if necessary, it can be removed by using an airbrush etc. Can be cleaned easily.
