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) l, and S
At step 2, the RAM clear subroutine is called.6 Next, 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
AM space FF0OH-FFFFH addresses are the device power supply○
It is designed to be backed up by a battery when in FF mode. FFO0H-FF20 of this RAM space
Address H is used as a nonvolatile memory area, and as shown in FIG. 14, this area stores information such as perforation count, film sensitivity, film type, and operation mode. f of the device! ! When the power is turned on again, this part of the RAM will not be cleared, 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. R.A.M.
The FF20+-1-FFFDH address in the space is 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 F02HNFFFDH (operation area) portion 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 subroutine for transitioning to the 1-machine initialization wait mode. When the subroutine starts, it is confirmed in S10 that 100 msec has elapsed, and then the process is stopped in S11.

It is determined whether or not it is the pack mode for projecting onto Kufilm.

If it is the pack mode, the process advances to 312, and if the document size is 8.5 inches x 1 inch, the process advances to S13 to set the size display for that document.

Set the motor flag to move to the 11 side. If it is determined No in S12, the document size display of 5 inches is set in 515, and the process further proceeds to 816, where a motor flag is set to move the pack film lens turret to the 5×7 side.

If 811 is determined as No, it is determined in 817 whether the document size is 8.5 inches x 1 inch or not, and if YES, the display of that size is set in 818, and 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 step 817, a size display of 5 inches is set in step 820, and the process proceeds to step 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 S11 to S22 described above are performed according to the data stored in the nonvolatile memory.

FIG. 19 is a flowchart of the initialization mode head return subroutine, in which processing for returning to the initialization mode is performed at 824.

In the image forming apparatus according to this embodiment, the film sensitivity (ISO) 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 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 FIGS. 20, 21, and 22, fl! is stored in the nonvolatile memory area. A check is made to see if there has been a change in ISO, film type, or original size with respect to the data before the power was turned off.

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 324. 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 set photosensitive film is a roll film, when it is confirmed in S25 that the ISO key has been pressed, the process proceeds 526 and it is determined whether or not the previous ISO stored in the non-volatile memory area was 40. If so, 8
The program advances to step 27, skips to the next ISO, and sets the display to 15O100.

If NO is determined 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 328 If the answer is No, the next work S○ display is set at 830.

In this way, the ISO change check is performed from l5O1→IS○
12→IS○40→l5O100-)ISO125→I
This is repeated in the order of SO400→rsot...

FIG. 21 is a flowchart of the film designation subroutine. When this subroutine starts, S3L
It is determined whether or not the film select key has been pressed, and if it has not been pressed (No), it is determined that the film has not been changed and is reset.

If the film select key is pressed, proceed to 832;
A film change flag is set for the motor control mode designation subroutine to be described later.

Next, in 533, 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 834; Using film (
That is, N in S33.

If there is a change in the film this time, the pack film display is set in step 335.

FIG. 22 is a flowchart of the document size specification subroutine. When this subroutine starts, 33
At step 6, it is determined whether the yK document size sensor is pressed or not.
As shown in Fig. 3, when the document size sensor 6 is on, the R document size is 5 inches, so
If the 5x7 size display is set in S37 and the document size sensor 6 is not turned on, the display will be 8.5 in 838.
A x11 size display set is created.

Then, for the motor control mode designation 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 M document size has been changed, the document size change flag is flagged at 840. Turn on.

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 341 whether or not the copy mode is in effect. If the copy mode is in progress, the shutter may be open, so in 842 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 back shutter motor is driven again to ensure that the shutter is closed.

FIG. 24 is a flowchart of the abnormality detection subroutine. When this routine starts, it is checked in S45 whether the roll turrets for roll film and pack film are operating normally, in S46 whether the roll shutter is operating normally, and in S47 whether the rear curtain magnet is operating normally. 848, whether the film winding operation is normal or not, S4
9 determines whether the flash lamp is operating normally.

Check whether the pack shutter is working properly on S50, sss
It is determined whether the operation of the second mirror is normal at step i, and whether the exterior cover is closed at step S52. If NO at each step, the process goes to the abnormal mode subroutine at step 553. There is.

FIG. 25 is a flowchart of a blue routine for displaying the number of films. When this routine starts, it is determined in 853 whether or not the prewind mode is set, and in S54 it is determined whether or not the rewind mode is set. If it is not in either mode, the process advances to S55 and the set photosensitive film is 40- It is determined whether the film is 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 at one, so there is no need to display the number of films, and the process proceeds to 556 to set the display off.

55 when it is determined that a roll film is set.
The process advances to step 7, where it is determined whether the print mode is selected. If copying is in progress, the number of flushes is set in step 558.

If the prewind mode is determined in S53, or the rewind mode is determined in S54, or the print mode is not determined in S57, that is, the film is wound halfway. In this state, the process advances to S59 and the number of films is calculated.

FIG. 50 shows a state in which rewinding has been completed.1 Normally, a large number of perforations 80 are formed along the longitudinal direction on both sides of the roll film 79.
The length of eight perforations corresponds to one frame of film photography. Buff olution is counted by a perforation counter including an optical sensor having one light emitting element and one light receiving element, and a counter for counting signals from the sensor. In addition.

81 in the figure is a patrone.

Returning to FIG. 25 again, the formula (n/8)-3 is used to calculate the number of films in S59.

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 S60.

FIG. 26 is a flowchart of the motor control mode command subroutine. When this subroutine starts, it is determined in S61 whether or not the document size has been changed. This determination is made based on whether the flag is set at 340 in FIG. 22.

If there is a change in the original size, it is determined at 862 whether the original size is 5 inches or not, and if that is the case, the process advances to 863 and it is determined whether the set photosensitive film is a pack film or not. . For pack film, use 864 and 5x lens turret for pack film.
Set the motor flag to move to the 7 side. Also, if the film set is a roll film, the S
Step 65 sets the motor flag for moving the roll film lens turret to the 5x7 side.

Also, if it is determined in S62 that the original size is not 5x7, it is determined in 866 whether or not the photosensitive film set is a pack film.The result of the judgment is 0, and if it is a pack film, 367 is for pack film! Set the motor flag to move the Non's turret to the 8.5x11 side, and if it is not a pack film, set the motor flag to move the roll film lens turret to the 6.5xti side at 868.

If it is determined that there is no change in the document size in S6L,
Proceeding to S69, it is determined whether or not the film has been changed. This determination is made based on whether the flag is set at 332 in FIG. 21.

If there is a change in film, it is determined in S70 whether the original size is 5 inches or less.

If it is that size, the process proceeds to 371 and it is determined whether or not it is a pack film. As a result of this determination, if it is a pack film, the second mirror is retracted from the optical path in S72, and a motor flag is set to move the pack film lens turret to the 5×7 side. If it is a roll film,

If the flag is not set in S77, it is determined in S79 whether the flag for moving the pack film lens turret to the 3,5X11 side is set, and the flag is set to O.
If N, move the pack film lens turret to the 3.5X11 side in S80.

If 879 is NO, it is determined in 881 whether a flag for moving the pack film lens turret to the 5x7 side is set, and if the flag is ON, the pack film lens turret is moved to the 5x7 side in S82. If NO in S81, it is determined in 383 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, S84
Move the roll film lens turret to the 5x7 side.

If NO at 883, it is determined whether a flag for moving the roll film lens turret to the 8.5X11 side is set (S85).

If the flag is ○N, use 586 to move the roll film turret to the 8.5X11 side.

If No in S85, it is determined in S87 whether a flag for inserting the second mirror into the optical path is set, and if the flag is ON, the second mirror is inserted into the optical path in 88B.

In this way, the second mirror, the roll film lens turret, and the pack film lens turret are each held in a predetermined position.

In the above embodiment, the first photosensitive film holding means and the second photosensitive film holding means are
There are different types of photosensitive film holding means. That is, although an example has been shown in which a roll film and a pack film are each set, the present invention is not limited to this, and 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; 1 For example, a reflecting mirror such as the first mirror is made rotatable, and the rotational movement causes the first imaging optical system and the second imaging optical system to be switched.
The optical path of the imaging optical system may be switched.

In the above embodiment, the case where two types of document sizes can be used has been described, but it is also possible to read image information from Ha 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 embodiment described above, the document size detecting means has a reference position W1 regulating section such as an M document size switching lever that is movable depending on the document size, and this reference position regulating section allows the document to be placed on the document table. When the document position is regulated, the projection position of the document image on the photosensitive film is ensured at an appropriate position (for example, at the center of the photosensitive film).

Furthermore, as in the above embodiment, if a lens exchange means having a plurality of lenses with different lens barrel lengths is arranged behind the reflecting mirror, the lens changing means If the longer lens of the lens barrel is constructed so as to move onto the optical path, it is possible to bring the one-reflection mirror and the lens exchange means as close as possible, thereby making it possible to downsize the apparatus.

Furthermore, in the present invention, the first photosensitive film holding means having an optical path with a short conjugate length is provided near the document mounting table,
A second photosensitive film holding means having an optical path with a long conjugate length is arranged in a line farther from the document mounting table.

If the arrangement positions of the above-mentioned first photosensitive film holding means and second photosensitive film holding means are reversed, the second photosensitive film holding means near the R stacking table is considerably higher than the document placing table. will be placed in position, while
The first photosensitive film holding means, which is further away from the stand, is placed at a very low position. Therefore, the operability of the apparatus, such as the attachment and detachment of the photosensitive film, as well as the appearance of the apparatus are unbalanced, and if the original table is set at the same height as the second photosensitive film holding means, the apparatus becomes larger.

In this regard, since the present invention is arranged as described above, the photosensitive film holding means does not partially protrude as described above, and the device has good operability and is compact.
It has features such as good overall appearance balance.
