2. Description of the Related Art Conventionally, in a camera, the storage position of a film cartridge with respect to an aperture may be on the right side or on the left side. In the method in which the movement of the film is detected during the film winding operation after shooting and the light emitting element for printing is blinked to print a character, the character font is output depending on the difference between the left and right positions of the film cartridge with respect to this aperture. The order is different.

Conventionally, two types of imprinting control ICs have been prepared and used depending on the situation in order to cope with this. However, the cost is high, and these processes are divided even in the assembly process at the factory. It is necessary to reduce the workability.

[Object of the Invention] The present invention has been made in view of the above circumstances, and flashes light-emitting elements arranged in a line in a direction perpendicular to the film feeding direction in synchronization with the movement of the film. In a camera projection device that performs imprinting, when viewed from the back of the film, in a camera where the storage position of the film cartridge is located to the left of the aperture, the output of imprinted characters is sentence head and the dot font at the left end of the characters. On the other hand, in the camera where the film cartridge is stored to the right of the aperture, the output of the imprinted character is output from the dot font data at the end of the sentence and the right end of the character. Switching means for switching the output order of dot font data according to the positional relationship between the It is an object of the present invention to provide a data imprinting device for a camera, which can realize a cost reduction and an improvement in assembling workability.

In the above configuration, when the camera power is turned on, the voltage detection circuit 8 outputs a reset pulse. When this reset pulse is input to the microcomputer 1, S in FIG.
The sequence is started from TART. The reset pulse is also input to the frequency dividing circuit 10, the year, month and day counters 11 to 13 and the message counter 20 at the same time, so that these are also reset. First, step # 001
In step # 002, the memory in the RAM area is cleared, and in steps # 002 to # 4, 0 is output to the dot LED lighting control ports (OPLEDL to H), and in step # 005, the D-flip-flop of the imprinting pulse detector is reset.

Next, in step # 007, the process waits for the data imprint to be enabled. Now, when a release switch (not shown) is pressed in a state where a film is loaded in the camera and shooting is completed, in FIG.
The camera control circuit 16 outputs a signal for driving a wind motor to wind the film, and the film is wound.
Since the input has been made from the port and iPDEN = 1, the sequence proceeds to step # 008. In step # 008, the imprint mode is determined, and if the date calendar mode is determined (i.e., iPCAL = 1), a font address for imprinting only calendar data is set in step # 011.

Here, first, the least significant digit (Di) is imprinted.
GiT0) middle address (PDO) for font designation
M) is loaded with the first digit of the calendar date (DAYL),
By loading 7 to the upper address and referring to the ROM font table (Table 4), if the upper address is 7, the same font as the value of the middle address is stored. The designation is the value of the first digit of the calendar date (DAYL). Similarly, the next digit after imprinting is the tenth digit of the calendar month digit (DAYH).
Value. Next, the third digit from the least significant digit (Di
GiT2) The specified font is the middle address (PD2
M) is 5 and the upper address (PD2H) is 9, so it is a blank font (see Table 4). D
The first digit of the month digit for iGiT3, the tenth digit of the month digit for DiGiT4, the first digit of the year digit for DiGiT6, DiGiT
7 is the tenth digit of the year, DiGit8 is "'" (single quote), DiGit5 and DiGit
For 9 to DiGiT 17, blank font addresses are respectively loaded.

On the other hand, if it is determined in step # 008 that the mode is the message mode (iPCAL = 0), the values of the message counter 20 are determined in steps # 009 to # 010 to determine the type of the imprinted message and to specify the font. Is set. FIG. 10 shows each copy message and the font address to be set in each copy digit.

In this example, assuming that the content of the message counter is, for example, 0, "HAPPY BIRTH" is as follows.
The data of the year is printed for each message of "DAY".
That is, DiGiT0 and DiGiT1 have fonts (yL and y) of the first digit and the tenth digit at the time.
H), DiGiT2 is set to “′” (single quotation), and DiGiT3 to DiGiT17 are set to “Y”.
ADHTRIB {YPPAH} "($ indicates a blank) and the address of the font are loaded. In this case, since the font is set from the last character as described above," \ HAPPY \ BIRTHDA "is displayed on the print.
Y'88 ”(Note: If the year of the calendar is 88, yL
= YH = 8), and the font is designated. Similarly, if the message counter is 1, "MER
RY @ CHRISTMAS'yH yL ", if the counter value is 2," @CONGRATULATIONS
! ”, If the counter value is 3

[0040]

[Outside 1] If the counter value is 4,

[0041]

[Outside 2] Is imprinted. Here, the value of the counter is 2, 3,
It can be understood from FIG. 10 that in the three cases (4), the year of the date data is not imprinted.

Next, when the mode is determined and a font is specified as described above, the printing order that changes according to the position of the patrone with respect to the aperture is determined in step # 012, and the DATSET subroutine is called to output the actual font. Will be

Here, when the switch 63 is off, μ-
Hi is input to the DiR terminal of COM1, and it is determined that the camera is a camera in which the patrone is located on the left side with respect to the aperture.
In other words, the character output is output from the end of the sentence.

The processing when outputting from the end of the sentence is DATS
This is performed in the ET-T subroutine.

The DATSET-T subroutine is described with reference to the flowchart of FIG. First step # 10
The first digit to be imprinted at 0 (the least significant digit on the print) The middle digit of the font designating address of DiGi0; P
The contents of the DOM are loaded into DACM, the middle digit of a 12-bit (4 bits × 3) counter that specifies the address when referring to the data table in the ROM.

Next, in step # 101, the FNTOUT subroutine for actually outputting the font is called after loading the contents of the PDOH into the upper digit of the address for font designation; also the upper digit of the data counter; DACH. Here, if the font of “A” is to be output by DiGiT0, DACM and DACH are respectively set to DAC.
H = 7 and DACM = A.

Next, the FNTOUT subroutine will be described with reference to the flowchart of FIG. First step # 20
If the direction of imprinting is determined by 0, and if it is determined that the data is output from the end of the sentence, the lower digit (DACL) of the data counter is set to 0 in step # 201, and the film screen size is determined in # 203 to determine the full size. iP (FiLS) = 1)
Then, in step # 204, the reset of the D-flip-flop 22 for detecting the imprint pulse is performed by the OPLAR.
It is released by setting ST = L. Then step # 2
05: Data counter; lower 4 bits (DACL), which is the contents of ROM address data specified by DAC, are set to OP
Output to LEDL port. That is, the aforementioned DiGiT0
In the case where "A" is output, the data counter; since the content of the DAC is H'7A0, the lower 4 bits of the data of the ROM address are B'1111 (see the font diagram of "A" in the upper left corner in FIG. 8). .

Next, in step # 206, the upper 4 bits (DACH), which is the content of the data stored in the ROM address specified by the data counter, are output to the OPLEDH port (in the case of the above-mentioned font "A", B 'is output). 00
11). Further, in step # 207, the lower 4 bits of the ROM address specified by the data counter in a state where 8 is added to DACL;
Output to PLEDH port. DAC = "A"
H'7A8, and the lower 4 bits become B'0000. In the embodiment, the first three bits are not connected to the output port, but in steps # 205, # 206, and # 208, the LED lighting control output port (OPLE) is set.
DL to H). In the sequence, the font output direction is determined again in step # 209, and 7 is subtracted from DACL in # 210. In step # 212, the input of the rising edge of the imprint pulse is waited. When the rising edge enters the clock of the D-flip-flop 22, its Q output becomes H (iPEDEC
T = H), the process proceeds to step # 213, and the D-flip-flop is reset. Here, it is the actual LED lighting time, but as shown in the timing chart of FIG. 4, the LED lighting is performed by 9 bits of font output (LEDL0-3, LEDL
(M0-3, LEDH0), the inverted signal of the imprinting pulse, and the imprinting enable signal are logically ANDed (see FIG. 1). It is limited to the low level period of the imprint pulse. Step 212
The D-flip-flop 22 detects the rising edge of the imprint pulse because the one-line LED of the font is used.
This is for detecting the end of lighting and setting the next font data.

Next, in step # 214, the font output direction is determined again, and in # 215, the lower digit of the data counter; DA
It is determined whether or not CL is equal to 8, and if it is equal to or smaller than 8, the processing of step # 203 and thereafter is performed again. In other words, 8 is added to the lower digit of the data counter in the previous flow; DACM so that the next line of the font is output thereafter (# 207).
7 (# 210), and as a result DACM is +
It becomes 1, and the data counter; DAC designates the data of the next column. In the case of “A”, (DAC) = H′7
A1.

When the output of the last column is completed (in the case of "A", H'7A7 and H'7AF), the DAC
L becomes 8 and branches at step # 215 to subroutine F
Ends NTOUT and returns. Step # 20
3 when the screen size is determined to be half size (Fi
(LS = L) is slightly different until the reset of the imprinting pulse detection D-flip-flop is canceled in step # 211. However, if the lower digit of the data counter is 1 or 5 in step # 218, the process proceeds to step # 218. D in # 219
If DACL is 1 or 5 by incrementing ACL by one, it will be skipped. Thereby, (9 ×
2 of A1 and A5 is removed from the font of 7), so that 7 columns become 5 columns (see FIG. 7B).

Thereafter, in steps # 220 and # 221, the data of the ROM address designated by the data counter is not directly output to the LED lighting output ports (OPLEDL to M), but the buffer RAM; LEDBL, LDB
The subroutine DATSHFT for copying data in the M and LEDBH and partially shifting the data in # 226 is called.

This DATSHFT subroutine is shown in FIG.
Described by That is, in step # 301, the LED
2 ^3-digit content of BL (FIG 13 (LEDBL) ₃ and the display; the same applies hereinafter) to determine the transfer of the value to 2 ² digits (# 30
2, 303).

[0053] Determine 2 ⁰ digit LEDBM at step # 304 transfers the value to 2 ^3-digit LEDBL (# 305,
306).

[0054] Determine 2 ² digit LEDBM at step # 307 transfers the value to 2 ⁰ digit LEDBM (# 308,
309).

[0055] Determine 2 ^3-digit LEDBM at step # 310 transfers the value to 2 ¹ digit LEDBM (# 311,
312).

[0056] Determine 2 ⁰ digit LEDBM at step # 313 transfers the value to 2 ² digit LEDBM (# 314,
315).

[0057] Step # 316 2 ³ digit 0 of LEDBM in, (see above Fig. 6) By the H'0 the LEDBH at step # 317 (9 × 7) 2 rows font than the D ₂ and D ₆ of The data is extracted and shifted to the lower digits, so that the number of rows becomes seven (see FIG. 7B).

When the data shift process is completed, the data shifted in steps # 227 to # 229 is transmitted to the LED lighting output port (OPLEDL to OPLE).
DH). Subsequent processing is equivalent to the case of the full size. (# 212 to # 216). In this way, when the printed font of one character has been output, DACL = 8, so the FNTOUT subroutine is exited from step # 215 and the next character (DiGiT
This is the font output of 1). Subsequent output of each character is the same as in the case of DiGiT0. In the DATSET subroutine, the start address of the font of each character is set, and the FNTOUT subroutine is called to actually output the font to the LED output port. .

Here, the last column of the font of each character (A7)
Contains a blank pattern for one row, so (DA
When CL = H'7 or H'F) 1 between each imprinted character
Dot blanks will be inserted.

Now, the final character (DiGiT17)
When the output is completed, the routine returns from the DATSET-T subroutine, and the # 013 wind motor 13 in FIG. 9 stops and the imprinting is disabled. When the disabling is disabled, the next imprinting is waited for again. A state is reached (see # 007), and a single imprinting sequence ends.

From the (9 × 7) dot font, (7
X5) Since a dot font is created, it is needless to say that it is necessary to select a font pattern so that there is no inconvenience in design as long as data is omitted and compressed according to a fixed pattern.

In the embodiment shown in FIG. 3, when the imprint mode is the calendar, only the order of "year, month, day" is prepared, so the year digit display section 15a, the month digit display section 15b, and the date digit display section Although only the portion 15c and the single quotation mark 15e indicating the year are displayed, the number of segments may be increased in order to display English month, time, and the like.

On the other hand, if it is determined in step # 014 that the DiR input port is LO, the font is output from the beginning of the sentence, and the font output subroutine DATSET- is executed.
H is called. The DATSET-H subroutine will be described with reference to FIG. In the DATSET-H processing, a font is output from the beginning of the sentence.
01 loads the digit of PD17 and calls the FNTOUT subroutine.

The difference from the case where the font is output from the end of the sentence in the FNTOUT subroutine is that # 200
And the DiR port is determined to be LO at # 202 and DA
The initial value of CL is set to 7. As a result, the font is output sequentially from the left end (blank in the embodiment).

In step # 207, 8 is added to DACL, and in step # 2
Since 9 is subtracted from 11 by 9, the output is sequentially performed in the direction of decreasing by one from the initial value 7. FIG. 15 and FIG. 16 show the operation at the time of imprinting accompanying film winding for the case of outputting from the beginning of a sentence and the case of outputting from the end of a sentence.
