13th rI! I is a flowchart of 5 main routines. When the main routine starts, the stack pointer is set in step (hereinafter abbreviated as S) 1, and the RAM clear subroutine is called in S2.
The subroutine table pointer is set in 83 and the subroutine table is searched (
S4).

FIG. 14 is an explanatory diagram of the RAM space, and FIG. 5 is an explanatory diagram of the nonvolatile memory area of the RAM space. R shown in Figure 14
The AM space address FF0OHNFFFFFH is the device's electric m0 address.
It is designed to be backed up by a battery when in FF mode. FF0OH-FF2O 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. When the device is turned on again, this part of the RAM is not cleared, so it takes 5 seconds! OF[
Data such as the number of perforations, film sensitivity, film type, original size, and operation mode are retained. 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-FFFDH in the RAM space are.

For example, it is used as an operation area to store input/output signals of various sensors, presence/absence of flags, etc.

FIG. 16 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. 17 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. 18 is a flowchart of the CPU initialization subroutine in the initialization mode. With the start of this subroutine, the port input/output mode is set at S6, tL, the port output is turned off at s7, a 2 msec timer is set at 58, and S
9 is not # [1! Load the memory data into the RAM of FF 201-1.

19th Fl! I is the *j-chart of the initialize wait mode transition subroutine. At the start of the subroutine, it is confirmed in S10 that 100 msec has elapsed, and then in S11 it is determined whether or not the pack mode is 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 third fs display for that document.

814 with 8.5X lens turret for pack film
Set the motor flag to move to the 11 side. If NO is determined in SI2, the document size display is set in 5.
Go to and set the motor flag to move the pack film lens turret to the 5x7 side.

If No is determined in the Sll, it is determined in 517 whether the document size is 8.5 inches
Proceed to 8.5X Shinstarlet 1- for pack film.
At the same time, set the motor flag to move the roll film lens turret to the 8.5X11 side (using a short lens barrel). If NO is determined in S17, a size display of 5 inches is set in S20, and the process proceeds to S21, where a motor flag for moving the roll lens turret to the 5×7 side is set.

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. 20 shows a flowchart 1 of the initialization mode head return subroutine, in which processing for returning to the initialization mode is performed in step 8211.

In the image forming apparatus according to this embodiment, the film sensitivity (130) is 12°40.100,1 as shown in the following table.
Six types of roll film, 25 and 400, can be used, and in the case of pack film, one with a film sensitivity (XSO) of 80 can be used. The selection of this tSO is made sequentially by pressing the ISO key 12 shown in FIG.

Also, as shown in the table, the amount of flash light changes depending on the number 130, and the amount of light emitted per flash is 1Ill! 1 is performed by a light emission amount adjustment volume 11 shown in FIG.

In addition, in this table, the first light emission mode, the second Jll light mode, the third light emission mode, and the fourth J? ! The intensity of the light intensity decreases in the order of the light modes.

In the subroutines shown in FIGS. 21, 22, and 23, fl! is stored in the nonvolatile memory area! The data before the source is turned off is checked to see if there has been a change in ISO, film type, or AG4 size.

FIG. 21 is a flowchart of the fSO designation subroutine for photosensitive film. When this subroutine starts, it is determined in step 324 whether it is a roll film or a C film, and if the photosensitive film set is a pack film, the ISO is set to 80 as mentioned above, so it is necessary to go through this routine. It will be reset without any problem.

If the set photosensitive film is roll film, if it is confirmed in S25 that the 80 key has been pressed, the previous ISO stored in the non-volatile memory area will be set to 40. If so, proceed to 827 and skip to the next ISO.
The display of too is not set, hru.

If NO is determined in 826, the process proceeds to 328, 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 set displayed in l501 is set to 829. If it is determined NO at tL, 828, the next 180 display is set at S30.

In this way, to check the ISO change, tsot→TSO
12→I SO40→150100→l5O125→I
This is repeated in the order of S0400→rsot...

FIG. 22 is a flowchart of the film specification subroutine. When this subroutine starts, S3
At step 1, it is determined whether the film select key has been pressed or not. If the film selection key 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 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 (
In other words, it is judged as N0 at 533, and if there is a film change this time, it is determined at 835 that the pack film display is not set.

23rd [1! is a flowchart of a 1M document size designation subroutine. When this subroutine starts, 3
At step 36, it is determined whether the [4i1 size sensor 6 is pressed or not. If the document size sensor 6 is on as shown in FIG. Since the document size is C, a display of 5×7 size is set in step S37, and if the original size sensor G is on and there is no streaking, a display of 8.5×11 size is set in step 838.

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

Figure 1524 is a flowchart of the pack shutter initialization subroutine. This subroutine is
This flow corresponds to the case where 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 while the shutter is open, the exposure will continue, so the shutter will be closed. Do the action 4] You must throw down.

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.

If the sensor is on, that is, if the shutter is open #h, the pack shutter motor is driven again to ensure the shutter is closed.

FIG. 25 is a flowchart of the abnormality detection subroutine. When this routine starts, it is checked in 845 whether the roll turrets for roll film and pack film are operating normally or not, in S46 whether the roll shutter is operating normally or not, and in S47 whether the f&curtain magnet is operating normally or not. 848 indicates whether the film winding operation is normal or not.
49, whether or not the flash lamp is operating normally.

Check whether the pack shutter is operating normally in S50.

It is not determined whether the operation of the second mirror is normal in S551 and whether or not the exterior cover is closed in S52.
If the determination at each step is No, the process goes to the abnormal mode subroutine at S53.

FIG. 26 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 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 856 to set the display off.

35 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 present or not. If copying is in progress, the number of flushes is set in step 858.

If it is determined in S51 that the film is in prewind mode, or if it is determined in S54 that it is in rewind mode, or if it is determined in S57 that the film is not in print mode, the film is in a state of being rolled up.

Proceeding to S59, the number of films is calculated.

FIG. 52 shows the finished state of the rear and C ends, and usually a large number of perforations 80 are formed along the longitudinal direction on both sides of the low puff (lumen 79). The length of the perforation corresponds to one frame of the shadow.Counting of the perforation is performed using an optical sensor equipped with a light-emitting element and a light-receiving element, and a counter that counts signals from the sensor. This is done by a perforation counter.

Note that 81 in the figure is a patrone.

Returning to FIG. 26 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. 27 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 or not the flag is set at 840 in FIG. 23.

If there is a change in the document size, it is determined in S62 whether the document size is 5 inches or not, and if that is the size, the process proceeds to 563 and it is determined whether or not the set photosensitive film is a pack film. . If it is a pack film, it is 864 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 65 sets the motor flag for moving the roll film lens turret to the 5x7 side.

If it is determined in 862 that the original size is not 5x7, it is determined in 866 whether or not the photosensitive film set is a pack film. 8
．． 5X11 (Set the motor flag to move it to 11, and if it is not a pack film, set the motor flag to move the roll film lens turret to 8.5X11 side at 568.゛S6 above)
If it is determined in step 1 that there has been no change in the document size, the process proceeds to S69, where it is determined whether there has been a change in film or not.

This determination is made based on whether the flag is set at 832 in FIG. 22.

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 advances to 871 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,

Furthermore, as in the above embodiment, when the lens exchange means having a plurality of lenses having different lengths of the lens barrel is arranged behind the reflecting mirror, after the reflecting mirror is retracted from the optical path, the lens exchange means If the longer lens is configured to move onto the optical path, it is possible to bring the 1-reflection mirror and the lens exchange means as close as possible, thereby making it possible to downsize the device.゛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, when a lens with a short lens barrel length is selected, one If the reflection mirror is allowed to be inserted into the optical path, the reflection mirror and the lens exchange means can be brought as close as possible, and the device can therefore be made smaller.

〔Effect of the invention〕

This is because the present invention has the configuration described above.

To provide an image forming device capable of obtaining clear images with simple operations without requiring complicated operations such as focusing and adjusting the position of a light source as in the past when creating slides or the like. Can be done.

Moreover, since the total amount of light can be corrected by detecting a single misfire, it is possible to prevent copy mistakes, and it is also possible to automatically detect deterioration or defects in the flash lamp, so it is possible to check when it is time to replace the flash lamp.
