(LMg) is a lens stop magnet, which will be explained later. When the distance signal and No. 4'3 related to the amount of lens extension match, the lens is demagnetized and the extension of the photographic lens is stopped.

In the camera according to the present invention which is capable of trimming, if the area to be printed on the film surface is reduced to a small size, such as in the trimming 3 mode, it is If you enlarge the image to the same size as the case, the enlargement magnification will increase. Therefore, blur and flare, which were not noticeable in the normal shooting mode, become noticeable. Therefore, in the camera of this embodiment, the minimum aperture value (that is, the limit value on the open side of the aperture) and the limit value on the slow side of the shutter speed are changed depending on the print range, and the depth of field is increased when performing cropping. At the same time, the shutter speed is increased to prevent camera shake. In addition, in this example,
Since it uses a lens shutter that also serves as an aperture,
If the minimum aperture value is increased, the shutter speed will also become faster, but the present invention is not limited to this, and may be configured such that only the minimum aperture value or only the limit shutter speed is changed in accordance with trimming. Also good.

The shooting mode, minimum aperture value, and limit shank speed on the low speed side in this example are shown in Table 3.
+nin indicates the limit shutter speed on the low speed side. This is shown in FIG. In the fjS18 diagram, the vertical axis is the aperture value,
The horizontal axis is the time after the shutter starts opening, and in normal shooting mode or trimming 1 mode, as shown in (A) 1, the aperture is 2.8 and the shutter speed is 1.
The aperture can be opened or the shutter speed can be slowed down to a combination of /30.

In the trimming 3 mode, as shown in (I3), it is only possible to open the fringes or lower the shutter speed up to the combination of fringes (F value) 5.6 and shutter speed 1/6o. Furthermore, in close-up mode, the aperture (F number) is 16 and the shutter speed is 1/1000.
Only combinations of can be set. Then, if proper exposure cannot be obtained with the above-described limited combination of fringes and shutter speed, a flash is automatically emitted. and,? As shown in the time chart at the bottom of Figure 518, for example, in the case of trimming 2 mode, the aperture (F number) is 5.6 and the shutter speed is 1760.
If the exposure is insufficient, the automatic focus adjustment circuit (AF)
At the time T1 when the shank opens, a signal is emitted from the output terminal (pos) of the control microcomputer (CMC) to trigger the flash. The output terminal (
A signal is issued from I)O,) to initiate the closing operation of the lens shutter.

Here, in this embodiment, the exposure value for switching to flash light emission (1η) is set so that it can be changed depending on the shooting mode Ev#J. Table 4 shows the relationship between

In Table 4, the exposure value E'v (or Eve) is determined by the apex calculation, where the subject brightness is Bν and the film sensitivity is S.
v, the aperture value is Av, and the shutter speed value is Tv, it is defined as Ev (presumably Eve) = By + 5v = Av + Tv.

The relationship between the aperture value and the shutter speed value when switching to this 7-lash light emission is shown in diagram fjS19.

In Fig. 19, the vertical axis shows the aperture value, and the horizontal axis shows the shutter speed value, and in the case of normal shooting mode without trimming and trimming 1 mode, the exposure value Ev is 8 to 1- as shown in (Da). Sometimes the flash is not emitted, but in the trimming 2 mode, the flash is not emitted only when the exposure value IEv is 10 or more as in (Ea). Furthermore, in the case of trimming 3 mode, (Fa
), the 7 lashes are not emitted only when the exposure value Ev is 12 or more, and in the case of close-up mode, the 7 lashes are not emitted only when the exposure value Ev is 1.8 or more, as shown in the figure (not shown). . This is because when the magnification during enlargement is large, the aperture is made as small as possible to deepen the depth of field.

Next, we will discuss the control microcomputer (CM) that controls the camera of this embodiment.

C) to the display microcomputer (DMC) from the output terminal T (PO, ) for display rewriting, the information necessary for display is transmitted, and the liquid crystal display device r! 1(L
CD, ) (LCD 2) is displayed.

Then, at #12, the photometry switch (Sl) is connected from the input terminal (PI, ) to the shirt release button (4).
If the open/closed state of the photometric switch (Sl) is detected and the photometric switch (Sl) is open (OFF), the state returns to #1 and enters the normal stop state of #4. If the photometry switch (Sl) is closed (
ON ), the signal of the output terminal (po, , ) is lowered at #13, and the external pressure of the flash circuit (F L ) is stopped. Then, in #14, the automatic focus adjustment circuit (AP) is activated by the start from the output terminal 7-(PO,) of the control microcomputer (CMC), and in #15, the automatic focus adjustment circuit (AP) is activated. - (PI2) while chanter release button (
The open/closed state of the release switch (S,) linked to 4) is detected. Here, if the release switch (S2) is open (OFF), return to #12, repeat the operation from #12 to #15, and press the chanter release button (
4) is pressed to the 2nd step opening and the release switch (S l
) is closed. If the closing of the second inch (s2) is detected in #15, the process proceeds to the shirt release operation from #16, which will be described later.

On the other hand, if it is detected in #6 that the winding switch (S, ) is closed (ON), it means that the film winding has not yet been completed, so the flow advances to #38 and the flash circuit (FL) is turned on. ), and the winding routine starts from #39. In step #3, the motor drive circuit (MD) is driven by a signal from the output terminal (POs) of the control microcomputer (CMc) to start the film winding motor (M) and start winding the film. And at #40, the winding switch (S,)
The film winding is completed by detecting the opening/closing state of the film winding switch (S).
, ) is released (OFF), the motor (M) is driven. Open the winding switch (S, ) with #40 (O
When FF) is detected, the rotation of the motor (M) is stopped in #41 to stop film winding, and the process proceeds to #42.

In the input terminal (r) of the control microcomputer (CMC'),
'16) detects the open/closed state of the film detection switch (s6), and if the film is not set to VCXA and the film detection switch (S6) is set to lff1 (ON), the information necessary for display is displayed at #45. Control microcomputer (CM
C) to the display microcomputer (DMC") and #
1 and enters the normal stop state at #4. At #42, the film is being wound and the film detection switch (S6) is activated.
When it is detected that #4 is open (OFF),
3, the open/closed state of the camera back switch (S,) is detected. Then, when the back δ is opened in well 43 and 'i miss inch S5) is closed (ON),
Proceeding to step 5, a microcontroller (CM) controls the information necessary for display.
The signal is transmitted from C) to the display microcomputer (DMC) and returns to step 1, where it enters the normal stop state at step #4. Furthermore, #43 has a back cover of 1. /If the back cover switch (S, ) is open (OFF) in the case of being irritated, proceed to #44, increase the count value of the film counter by 1'', proceed to step #45, and proceed to #45 to increase the count value of the film counter by 1", which is necessary for display. This information is transmitted from the control microcomputer (CMC) to the display microcomputer (DMC), and the process returns to #1, and the normal stop state occurs in #4.In other words, with this configuration, when the back cover of the camera is opened, The film counter does not increment when no film is loaded.

Next, the release routine starting from #16 will be explained. In #16, first, the photometric signal kj, which takes into account the film sensitivity, is input from the A/D converter (A/D) to the input terminal (PIAD) to the control microcomputer (CM C"). Therefore, this photometric signal is the photometric data Evu+.In #17, in the camera of this embodiment, as shown in FIG. The exposure value EvC that can be switched to is read from the ROM.Then, in #18, the metering data Evm is compared with the exposure value Evc that can be switched to 7-lash shooting, and Ev+
If n>Evc, proceed to #25, which will be described later. -Sword, E
If νm>Evc, it means that the photometry data is lower than the exposure value Evc for switching to 7-lash photography, so in #19 the control microcomputer (CMC) input IT-(P
1' Check whether the main capacitor for flash output of the flash circuit (FL) is completed from T, ).
Separate. And if this charging is completed, #20
Proceed to set the flash photography flag to instruct flash photography. If this charging is not completed yet, return to #1 and wait for this charging to be completed in #4.

I21 determines whether the shooting mode is set to close-up mode or apricot, and if it is not close-up mode, in #23, the L1 dynamic focus, α adjustment circuit (A F ) color is sent to the illumination H microcomputer (CMC). Input terminal (PIAF
), a signal related to the subject distance is input. On the other hand, if it is determined in #21 that the close-up mode is set, the process proceeds to #22 and the control microcomputer (C
An "H" signal is transmitted from the output terminal (r' o , ) of the MC) to the automatic focus adjustment circuit (AF), and the subject distance signal is forcibly made into a signal corresponding to the closest distance. Then, in #23, a signal regarding the subject distance is similarly input from the automatic focus adjustment circuit (AF) to the control microcomputer (CMC) via the input ME'-(PIAF).

In #24, the control microcomputer (CMC) connects the terminal (PIA
RO the value according to the subject distance Ibo number input from F).
The light is read from M and set in the light emission timing timer provided inside the control microcomputer (CMC). If you want to take a 7-day photo shoot, use Flashmatic 8! This is because the fringe value is determined according to the subject distance depending on the structure, and the 7-lash light emission timing is determined according to the aperture value as shown in FIG. Next, #25
Then, the control microcomputer (CMC) reads a value corresponding to the shooting mode from the ROM and sets it in the exposure limit timer.

This is because in this embodiment, the minimum aperture value and minimum shutter speed are limited depending on the shooting mode (CP).

At #26, the control microcomputer (CMC) output '47-(
An imprint signal is output from r: 'o, . And in #27, the control microcomputer (CMC)
The shutter magnet (SMg) is excited by the rise of the signal from the output terminal (PO, ), and the release magnet (RM and) is activated by the signal from the output terminal (PO, ). 'fF1 is started and the photographing lens is extended after a certain period of time. And #2
8, the input terminal of the control microcomputer (CMC) - (Pl, t
) detects the open/closed state of the count switch (S, ) and waits for the count switch 7 (S7) to close.
Here, when the count switch (S7) is closed at the beginning of the shirt release operation, the process proceeds to #29 and the integration of the exposure amount is started. Here, the photometry system of this embodiment has a sub-diaphragm whose aperture diameter changes according to the amount of light transmitted by the lens shutter, and when the integration of the exposure amount starts, the condenser (
Charging of C1) is started.

In #30, it is determined whether or not the 7-ray photography flag that instructs flash photography is set, and if the 7-ray photography flag is set, the process proceeds to #31 and the above-mentioned flash timing timer is set. Start it, enable timer interrupts, and proceed to #32. If the 7-lash shooting flag is not set in #30, the process directly proceeds to #32, and in #32, the exposure limit timer, which has been set for one hour according to the appropriate exposure amount, is started. Whether this timer overflows or not at step 33 continues to be determined.

Here, in this embodiment, since a lens shutter is used that functions as both an aperture and a shutter speed, the fringe value and shutter speed value can be set at the same time by one exposure limiting timer. However, it is also possible to configure the aperture and the rotation speed to be controlled separately so that the combinations of the aperture and the rotation speed can be varied.

When an overflow of the exposure limit timer is detected in #33, the process proceeds to #34 and the control microcomputer (C
MC) output terminal (Pop) 47. When the number starts up, the trannostar (TR) becomes conductive, the shutter magneto (SMg) is forcibly demagnetized, the shutter that also serves as an aperture is closed, and the exposure is completed, and the shank is closed at #35. Wait for the specified amount of time until it finishes closing, then close #3.
Return to the winding routine from 9.

Here, the timer interrupt routine in #31 is shown in FIG. 21. First, when a timer m interrupt occurs, the timer interrupt is disabled in #36, and the output terminal of the control microcomputer (CMC) is disabled in #37. The signal from (P O, ) rises and the 7-ranoshu-issue signal is issued, causing the 7-ranoshu to be issued "#:" and returning to the original step.

Next, regarding the operation of step #8 in Figure 1520, rjS
This is shown in more detail in Figure 22. FIG. 22: First, #8-1 detects the open/closed state of the trimming key switch (S,), and if the visiting key switch (S3) is closed (ON), #8-1 detects the open/closed state of the trimming key switch (S). Proceed to #2, change the trimming mode Renostar by one step, and proceed to #8-3. If the trimming key switch (SJ) is open in #8-1, #8
Rub #8-31 without passing through -2. In case 8-3, from the sensitivity of the loaded film input from the switch (CAS) to the input terminal (PIDX'), it is determined that the film sensitivity is 15O100O or more, but it is t'11
F! It will be R.

And if the sensitivity of the loaded film is l5O1
If it is 00O or more, proceed to #8-4, and it is determined whether the trimming mode is below 2 or apricot, and if it is below the trimming 2 mode, proceed to #8-5, which is normal JsL without trimming.
Shadow mode 1: Changed.

-77, the sensitivity of the film loaded in #8-3 is l
If fq is determined to be less than 5O100O, the process proceeds to #8-6, where it is determined whether the sensitivity of the film is greater than or equal to 15O400. If it is 15O400 or more, proceed to #8-7, and it is determined whether the trimming mode is below 3 mode, and if it is below the trimming mode 3 mode, proceed to #8-7.
8 returns you to normal shooting mode without cropping. Well 8
-6 and the film sensitivity is not above ISO 400, and when the setting is #8-7 and the trimming mode is not below 3, the shooting mode is not changed.

Therefore, according to this embodiment, as shown in FIG. 23, if the sensitivity of the loaded film is less than 15O400, each time the trimming setting button (8) is pressed, the normal shooting mode is changed to the trimming 1 mode. , from trimming 1 mode to trimming 2 mode, from trimming 2 mode to trimming 3 mode, from trimming 3 mode to close-up mode, and from close-a-knob mode to normal shooting mode, while ISO 40
If 0 or more and less than 100O, trimming 2
When the trimming setting button (8) is pressed from the mode, the mode returns to the normal wL shadow mode, and the trimming 3 mode and close-up mode are not set.

Furthermore, if a high-sensitivity film of 15O100O or higher is used, pressing the trimming setting button (8) from the trimming mode returns to the normal shooting mode.
It is not set in trimming 2.3 mode and close-up mode. This is because the higher the sensitivity of the film, the more illuminating the grains will be, and the higher the sensitivity of the film, the less desirable it will be for cropping photography that requires a large enlargement magnification. The limits for trimming differ depending on the film speed.

Next, the operation of the display microcomputer (DMC) of this embodiment will be explained using charts 70 from FIG. 24 to FIG. 26. First, in the display microcomputer (DMC), all human output ports and memory are initialized in #46. For example, the clock mechanism built into the display microcomputer (DMC) is initially set to "85 Hayabusa, January 10," the shooting mode is set to normal shooting mode, and the count value of the film counter is set to 0. Next, in #t7, the stored contents of the data required for display and imprinting on the film are decoded.Then, in #48, this data is transmitted to the liquid crystal drive circuit (LCDR), and the liquid crystal display device Necessary information is displayed by (LCD, ) (LCD2), and all interrupts are permitted in #49, and the normal stop state is entered in #50.

- rjS25 Figure 70 is a 70-chart showing a timer interrupt to this display microcomputer (DMC), and this timer interrupt is configured to occur every second.

First, when a timer interrupt occurs, a calendar calculation is performed in #51 based on the clock built in the display microcomputer (DMC) + a clock, the calculated data is decoded in #52, and the liquid crystal is driven in #53. It is output to the circuit (LCDR), the display is changed, and the process returns to the original step in #54.

Furthermore, FIG. 26 shows an interrupt for changing the display and an opening for imprinting the hood on the film 70.
-It is a chart. First, when the input signal to the interrupt terminal (int+) of the display microcomputer (DMC) rises and an interrupt occurs, the timer interrupt shown in FIG. 25 is inhibited at #55.

Here, if a timer interrupt occurs after #55, it is stored in memory, and the interrupt is configured to be executed immediately after the timer interrupt is enabled. Then, in #56, display data such as the count value of the film counter and the shooting mode are input to the input terminal (pi).
D), the data and date data are decoded at #57, and the decoded data is outputted to the liquid crystal drive circuit (LCDR) at #58 to display the liquid crystal display device (
Change the display of L CD 1) (L CD 2) and select #5.
At step 9, enable the timer interrupt and return to the original step.

On the other hand, the interrupt terminal (in
When the input signal to Lz) rises and an interrupt force is applied, #61 disables the timer interrupt shown in the f525 diagram, and #62 disables the date print selection switch (S,) connected to the input terminal (pi,). Detect open field state. If this date print selection switch (S,) is open and date printing is not selected, proceed to #63, decode the data corresponding to the hood that prohibits date printing, and proceed to #65. Proceed to. On the other hand, if the Roy 1 print selection switch (S8) is configured in #62 and date printing is selected, the data corresponding to the date to be printed is decoded in #64 and Proceed.

In #65, the sensitivity of the loaded film is read from the input terminal (piDX) connected to the switch (CAS), and in #66, the code imprinting time (i.e., the light emitting diode) is determined according to the read film sensitivity. (3, 2a)) is determined, and imprinting of the code is started in #67. When the imprinting time determined in #68 is counted, the imprinting is finished in #6, and the progress timer interrupt is permitted in #59.

Next, we will explain the configuration of the automatic printer included in the system of this embodiment, which automatically prints the film taken by the camera of this embodiment onto photographic paper.
It is shown in Figure 7. In the Pt527 diagram, (LA) is a lamp for printing, (CF) is a color filter for color balance adjustment corresponding to 37'7 colors of red, green, and blue, (EL) is a lens, and lamp (LA) The light emitted from the film passes through a color filter (CF) and a lens (EL) and is irradiated onto the film (F) at the printing position. Then, the light transmitted through this film (F) is transmitted through the printing zoom lens (
r'L) onto the photographic paper (p, -p) and printing is performed.

The configuration of this automatic printer will be explained below along with its operation.

First, (50) is a lamp control circuit that controls the lighting/extinguishing state of the lamp (LA). It is also used for reading imprinted codes, color balance, and metering for determining exposure.

Reference numeral (52) denotes a film conveying device that feeds the film photographed by the above-mentioned camera toward the carrier of the printer, and feeds the film (F) rightward in the figure. The density of the film being sent to the right is CO
It is monitored by the D line sensor or MO8 type line sensor (54), and this MO8 type line sensor (
Screen edge detection device (56) into which the output of 54) is input
When it is detected that the density of the film being monitored has changed, the feeding of the film by the film transport device (52) is stopped. That is, as shown in the time chart of FIG. 28, the screen edge detection device (5G)
Signal (a) input to the film transport device (52) from
By falling, film advance is stopped and one frame of film is just positioned to be printed. Furthermore, the seven frames of the film that have been printed are sequentially wound up by a film winding device (not shown) 6 Then, when the film feed is stopped, a signal is emitted from the film transport device (52). In step (b), the code reading device (58) is activated, and the code imprinted near the frame at the position where the film (F) is printed is read via the line sensor (GO). In other words, the photographing z mode of the frame printed by the hood reader rIL (58), whether or not to print the date, and each image of the printed area weight.
The information is read. And a code reader (58)
The shooting mode information read by the A word (c)
, a zoom lens control device for photometry (62) that sets the printing magnification of the zoom lens for photometry (PL), and a zoom lens control device for photometry (64) that sets the magnification of the zoom lens for photometry (ML). ). The magnification of both zoom lenses (ML) and (PL) is set according to the information of the shooting mode, and if cropping is specified at the time of shooting, the photometry range on the frame and the photographic paper are set according to the trimming size. The enlargement magnification is determined. With this configuration, even if a mode that specifies cropping is set at the time of shooting, only the area to be printed can be accurately cropped, and regardless of the cropping size, the image can be printed to a specified size. It can be stretched and printed.

And the photometric zoom lens control system fi! When the magnification setting of the photometric zoom lens (ML) is completed by (64), the exposure amount low circuit (
66) is performed. This exposure calculation is
This is done based on the output of the photometry circuit (68) which receives the light from the frame at the printing position via the photometry J-rozoom lens (ML), and calculates the color balance and exposure amount according to the 7 frames. . The color balance information calculated here is transmitted to the filter control device (70) as a signal ((・) and used for color balance adjustment (-)j, and the exposure information is transmitted as a signal (r). is transmitted to the lamp filJ circuit (50) as a lamp (LA
) is used to determine the amount of light emitted. Further, the symbol (g) indicating the end of photometry is also transmitted from the exposure calculation circuit (66) to the lamp control circuit (50), and the lamp (LA) is temporarily turned off.

Next, the filter control device (70) controls the color filter (CF) according to the color balance information flu from the photometric circuit (68).
), and when the seven steps are completed, the filter control device (70) sends a signal (1
1) is emitted.

This No. 111 (h) includes a lamp control circuit (50) and a shutter control device '1 (72) that controls the opening and closing of the shutter (ps) located at the edge of the photographic paper (PP) at one print position. , and control whether or not to print [] on the screen of the photographic paper being printed.
) print control device (74)).

Here, I, 7 regarding L1 attached printed on photographic paper.
The clothes are decoded from the hood reader (58) via the decoder (76) and sent to the fabric weight print control device (7,1,
), and the date print control device 74)
sets the year and month of the date board (78) that shows the basis weight printed in response to this report.

Then, when the signal (11) is input, the shutter control device (72) starts to IHI the negative/return (P S ), and the lamp control device (50) starts to IHI after this signal (11) is input. After a certain period of time until the shutter (ps) is fully opened, one lamp (LA) is turned on and printing is performed. On the other hand, if date printing is selected using the hood imprinted on the film, the date printing control device (7・t) will operate at a constant rate from when the signal (II) is manually applied until the shutter (PS) is fully opened. After a while, turn on the lamp (LD) and print the date. Here, (DL) is a lens for printing the date, and the date set on the date board (78) is projected and printed on the screen of the photographic paper by the lens (DL) for printing the f size. Ru. If printing of the date is not selected by the code imprinted on the film, the lamp (LD) will not be lit and the basis weight will not be printed.

Here, the lamp (LD) for date printing is turned on H, 7.
The time between 1 and 1 is controlled by the date print control device Z (74,) so that the time is constant g, +1. Controlled lamp (LA)
Burning by 1! ,? The light emission amount of the lamp for date printing (LD) is set so that it is #J shorter than the opening.On the other hand, the lamp for film printing (LA) is set for one lighting time according to the exposure amount information. and the light intensity are controlled by a lamp control circuit (50).

When printing by the lamp (LA) is completed, the lamp control circuit (50) turns off the lamp (LA) and then outputs an exposure completion signal (j). In response to this exposure completion signal (j), the film transport device (52) starts feeding the film, and the shutter control 8 device (
72) causes the shutter (P'S) to close.

Further, in response to this exposure completion signal (j), the photographic paper transport device (80) sends out the photographic paper (r'p) in the direction Aj in the figure in preparation for the next printing. Also, this exposure completion signal (
j), the screen edge detection device (56), code reading device (58), exposure calculation circuit (66), and filter control device (70) are each reset to prepare for the next printing. Then, the printed photographic paper is sequentially stored in a photographic paper storage device (not shown), and the printing process is performed.

Incidentally, in the camera of this embodiment, since the printing date is recorded on the film in the form of a code, it is difficult to recognize the printed area weight even by looking at the film as it is. Particularly when using reversal film, which is rarely printed on photographic paper, even if the date is imprinted on the film with a hood, the date is of little use.

Therefore, in case such versatile film is used, one camera has a built-in date imprinting device that imprints [ ] as a numerical value on the screen of the film as in the past. If the date is imprinted on the film, the date may be imprinted on the film as a numerical value using the two-position setting. Here, to determine whether a normal 7Y film is loaded or a versatile film is loaded, check the f+? It is sufficient to use the film latitude information in the report. Therefore, information regarding the film latitude (for example, data called "exposure range") is determined from among the film sensitivity information input from the switch (CAS) of this embodiment, and the loaded film is determined to be a reversal film. If this is not possible, the configuration can be configured to use a conventional date imprinting device that imprints the date on the film as a numerical value.Alternatively, depending on the film being loaded, a date imprinting device can be used manually. It may also be configured such that it is selected.

Furthermore, since printing is not normally performed in the case of a reversal film, it may be configured to prevent switching to the trimming mode when it is determined that a reversal film is attached. In the camera of this embodiment, the trimming size can be changed to three types, and the minimum F value (maximum aperture diameter) and maximum shutter speed are changed according to each trimming size. The present invention is not limited to this, but may be configured to change the minimum F value or maximum shutter speed depending on whether or not trimming is performed. Further, when such a limit value is changed, the value for issuing a warning such as a camera shake warning may be changed depending on whether trimming is performed or not. Furthermore, in this embodiment, the flash was configured to fire automatically if proper exposure could not be obtained even when the shutter speed reached its maximum value. In some cases, the light-emitting part of the camera may be configured to protrude from the camera body to encourage the use of a flash.

In addition, for cameras with automatic exposure control mode, in the case of automatic aperture-priority shutter speed control mode that prioritizes the aperture over the set value, restrictions are placed on the set aperture value depending on whether or not cropping is performed. In addition, in the case of a program mode in which the aperture is automatically controlled and a shutter speed priority automatic aperture control mode, the calculated aperture value may be limited by one.

Furthermore, although the camera of this embodiment is configured so that the aperture and shutter speed change in a triangular shape as shown in FIG. In this case, the height of the trapezoidal shape may be limited to limit the embossed pattern.

Furthermore, although the automatic printer of this embodiment is configured to print data at the corners of the area where the subject is printed, the invention is not limited to this; The image may be configured to be printed in the white frame. Furthermore, if data is also printed within the area where the subject is printed, the color of the printed data may be changed so that the data can be easily distinguished. Alternatively, the configuration may be such that a position of a color where data is easily distinguished is searched for and the data is printed at that position. Then, the optical system for data printing is adjusted so that the position and size of the data to be printed are adjusted according to the print size, making it easy to check the printed data, and adjusting the position and size of the data to be printed. You may choose not to have any effect.

Furthermore, the code imprinted on the film may be configured to be imprinted as a magnetic code on a magnetic recording layer coated on the film. The data to be imprinted as a hood is not limited to the photographing date as in the embodiment, but may also be hour, minute and second data, photographic exposure data, serial number, etc.

Incidentally, in the automatic printer of this embodiment, the printing optical system and the photometric optical system were provided separately.
A part of them may also be used, for example, a photometric light receiving element may be arranged on the Nyanta (PS) shown in FIG. 27.

In addition, in the above embodiment, the imprint data is configured to be imprinted outside the photographed screen, but the imprint data is not limited to this, but may be placed in a predetermined corner or near the bottom of one screen to be photographed. A light shielding means for blocking light from the subject is provided on the headrest, and the light is shielded by this light shielding means only when trimming is selected or all the time.
It may be configured such that the imprint data is imprinted in the light-shielded area.

Furthermore, in the above embodiments, liquid crystal display devices were used for display within the viewing field of view and for display on the top surface of the camera, but the present invention is not limited to this. For example, display using light emitting diodes may be used. It's okay. Furthermore, in the above embodiment, even in the normal shooting mode in which no trimming is performed, the liquid crystal display device on the top of the camera displays a display corresponding to the area to be printed. It is also possible to eliminate this display and display a display according to the range to be printed only in the trimming mode. 1. In the above embodiment, even if the Y rimming mode is set, the magnification of the fining is not changed, but the area to be printed is displayed. However, the area outside the area to be printed is It may be configured such that only the area that is always printed while being shielded from light by the liquid crystal display device is displayed within the 7T inder.

Further, in the above embodiment, a push button (8) is provided for setting the photographing mode, but a slide switch or a changeover switch may be used instead.

In the above embodiment, when the close-up mode is set, the photographing lens is set to the closest position, but a close-up position may be provided instead of the closest position. .

Further, in a camera in which the focal length of the photographing lens can be changed, the lens may be configured to be set to the long focal length side when the close-up mode is set.

(Left below) Shocking! Shuttle 1 (As detailed above, the present invention provides a photographing mode switching means capable of switching between a normal photographing mode for photographing a normal photographing range and a trimming mode for instructing a narrower cropping range; A close-up mode setting means capable of setting a close-up mode for close-up photography; a recording means for recording information indicating that cropping has been instructed on the film when the close-up mode is set; When the close-up mode is set, the VF feature includes a lens control means for setting the shooting distance of the photographic lens to a predetermined distance. When the close-up mode is set, information is written on the film so that cropping can be performed during printing, and the photographic lens is adjusted to a predetermined distance. Therefore, without bringing the camera close to the subject (by taking a picture and increasing the enlargement magnification when printing, a photograph similar to a close-up photograph taken with a conventional camera can be obtained. By installing a close amplifier lens in the
It is inexpensive because there is no need to move the photographic lens to take close-up photographs, and there is no need to get close to the subject, so there is no need to change the focus detection device or the photographic lens for close-up photography. There is no undesirable effect on performance.
