Tables 2 and 3 show the data memory in RAM and their contents. Table 4 shows the fonts in ROM. 5 is a table showing data addresses and fonts stored therein.

The stored fonts are numbers 0-9, alphabets AZ,
There are a total of 46 symbols with 10 symbols.

Table 5 is a table showing the value of the message counter and the contents of the message corresponding to the count value.

When the power is turned on to the camera in the above configuration, the reset pulse is output from the voltage detection circuit 8. When this reset pulse is input to the microcomputer 1, the START in FIG.
Start the sequence. The reset pulse is also input to the frequency dividing circuit 10, year, month, and day counters and 11 to 13 message counters 20 at the same time.

First, in step # 001, the memory in the RAM area is cleared, and in steps # 002 to # 004, 0 is output to the dot LED lighting control ports (OPLED to H), and step # 005
Resets the DF / F of the imprint pulse detector.

Next, at step # 007, the process waits for the data imprint to be enabled. Now, when the film is loaded in the camera and the release switch (not shown) is pressed to end the photographing, in FIG. 1, the camera control circuit 16 outputs a signal for driving a wind motor for film winding, and the film is wound. However, this motor drive signal is input into the microcomputer 1 from the iPDEN port, iPDEN = 1, and the sequence proceeds to step # 008. In step # 008, the imprint mode is determined, and the date calendar mode is determined, that is, (iP
If CAL = 1), the address of the font for imprinting only the calendar data is set in step # 011. Here, the first digit (DAYL) is loaded into the calendar date digit at the middle address (PDOM) for the font instruction of the least significant digit (DiGiT0) for imprinting, and 7 is loaded into the upper address. Referring to the ROM font table (Table 4), in the upper address 7, the same font as the value of the middle address is stored. In this case, the font of the least significant digit to be imprinted is designated by the first digit (DAYL) of the calendar date digit. ). Similarly, the next digit of the imprint is the calendar month digit.
The value of the 10th digit (DAYH). Next, the font specified as the third (DiGiT2) from the least significant digit of the imprint is a blank font because the middle address (PD2M) is 5 and the upper address (PD2H) is 9 (see Table 4). Similarly, the first digit of the month digit for DiGiT3, the tenth digit of the month digit for DiGiT4,
1st digit of year digit for DiGi6, 10th digit of year digit for DiGiT7, DiG
"'" (single quotation) for iT8, DiGiT5
For DiGiT9 to DiGiT17, the addresses of blank fonts are loaded.

On the other hand, in step # 008, the mode is determined to be the message mode (iPCAL
= 0), the type of the message to be imprinted is determined by determining the value of the message counter 20 in steps # 009 to # 010, and the address for designating the font is set. FIG. 10 shows each copy message and the font address set in each copy digit.

In this example, assuming that the content of the message counter is, for example, 0, the message “HAPPY BIRTHDAY” and the data of “year” are printed as follows.

That is, fonts (yL and yH) of the first and tenth digits of the year at that time are set in DiGIi0 and DiGIi1,
GiT2 is "'" (single quotation), DiGiT3 ~
DiGiT17 has And the address of the font are loaded, in this case the font is set from the last character as described above, so on the print (Note: The font is specified so that it is displayed as follows (when the calendar year is 88 years, yL = yH = 8). Similarly, if the message counter is 1, If the counter value is 2 If the counter value is 3, If the counter value is 4, Is imprinted. Here, it can be understood from FIG. 10 that when the value of the counter is 2, 3, or 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 DATSET subroutine is called in step # 012, and actual font output is performed. The DATSET subroutine is described with reference to the flowchart of FIG.

First, in step # 100, the first digit to be imprinted (the least significant digit on the print): the middle digit of the address for specifying the font of DiGiT0; 12 bits for specifying the contents of the PDOM when referencing the data table in the ROM (4 bits x 3)
The middle digit of the counter; load into DACM.

Next, in step # 101, the contents of the PDOH are also loaded into the upper digit of the font designation address; the upper digit of the data count; DACH, and then the font is actually output. Call the FNTOUT subroutine. Here, temporarily, DiGi
When the font “A” is output at T0, DACM and DACH are set to DACH = 7 and DACM = A, respectively. Next, the FNTOUT subroutine will be described with reference to the flowchart of FIG. First, the lower digit (DACL) of the data counter is set to 0 in step # 200, and the film screen size is determined in # 201. If it is determined that the film is full size (iP (FiLS) = 1), the imprint pulse is detected in step # 202. DF / F, 22 reset is OP
It is released by setting LARST = L. Then step # 2
At 03, a data counter; outputs the lower 4 bits (DACL), which is the contents of the ROM address data specified by the DAC, to the OPLEDL port. In other words, the case where "A" is output in the above-mentioned DiGiT0 will be described. Since the content of the data counter; DAC is H'7A0, the lower 4 bits of the data of the ROM address are B'111.
(Refer to the font diagram of "A" in the upper left corner of FIG. 8) Next, in step # 204, 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", it becomes B'0011). Further step # 205
To output the lower 4 bits of the ROM address specified by the data counter to the OPLFDH port with 8 added to DACL. DAC = "A"
H'7A8 and the lower 4 bits become B'0000.
In the embodiment, the first three bits are connected to the output port, but in steps # 203, # 204, and # 206, the LED lighting control output ports (OPLEDL to OPLL) are connected.
The font data is output to EDH). In the sequence, 7 is subtracted from DACL in step # 207, and the input of the rising edge of the imprint pulse is waited in step # 208. When the rising edge enters the clock of DF / F22, its Q output becomes H (iPDEDCT = H), and the process proceeds to step # 209 to reset D / F-F. Here, it is the actual LED lighting time, but as shown in the timing chart of FIG. 4, the LED lighting is 9 bits of font output (LEDL0-3, LEDL0-3,
LEDM0 ~ 3, LEDH0) and the logical sum of the inverted signal of the copy pulse and the copy enable signal (see Fig. 1). Is limited to the low level period of the imprint pulse (▲ ▼). In step # 208 and DF / F22, the imprint pulse (▲
The rising edge of ▼) is detected in order to detect the end of lighting of one line of the LED of the font and set the next font data.

Next, in step # 210, it is determined whether or not the lower digit of the data counter; DACL has become 8, and if it is 8 or less, step # 20 is performed again.
Perform the processing from 1 onwards. In other words, 8 is added to the lower digit of the data counter in the previous flow; DACM is added (# 205), and 7 is subtracted (# 20) so that the output of the next line of the font is output thereafter.
7) As a result, the result is +1 and the data counter; DA
C will specify the data in the next column. In the case of "A", (DAC) = H'7A1.

When the output of the last column is completed (H'7A7 and H'7AF in the case of "A"), the DACL becomes 8 and the routine branches at step # 210 to terminate the subroutine FNTOUT and return. On the other hand, when the screen size is determined to be the half size in step # 201 (FILS = L), the process is slightly changed, and the process proceeds to step # 21.
It is the same until the reset of the DF / F for imprinting pulse detection is canceled in 1; however, if the lower digit of the data counter is 1 to 5 in step # 212, the DACL is set to 1 in step # 217.
By incrementing, and skipping when DACL is 1 to 5, A1 is converted from (9 × 7) font to A1
And A5 are extracted, and the number of rows is reduced to five (see FIG. 7B). Thereafter, in steps # 213 and # 215, the data of the ROM address specified by the data counter is transferred directly to the buffer (RAM; within LEDBL, LEDBM, and LEDBH) without being directly output to the LED lighting output ports (OPLEDL to M).
In 218, a subroutine DATSHFT for partially shifting data is called.

This DATSHFT subroutine is described with reference to FIG.

That is, in the FIG. 13 a 2 ^3-digit content of LEDBL at step # 301 (LEDBL) ₃ and display: Determine hereinafter the same), transfer the value to 2 ² digits (# 302, 303).

Step # 304 determine the 2 ⁰ of LEDBM in two of LEDBL that value
Move to ³ digits (# 305,306). In step # 307 to determine the 2 ² LEDBM transfer the value to 2 ⁰ digit LEDBM (# 308,309). In step # 310 to determine the 2 ³ LEDBM transfer the value to 2 ¹ digit LEDBL (# 311,312).

Step # 313 determine the 2 ⁰ of LEDBH in two of LEDBM that value
Transfer to ^two digits (# 314,315). Step # 316 0 2 ³ digit LEDBM in, # LEDBH By the H'0 at 317 (above 6
(See FIG. 7), two lines of data D2 and D6 are extracted from the font of (9 × 7) and shifted to the lower digits, so that the number of lines becomes seven (see FIG. 7 (B)).

When the data shift process is completed, the data shifted in steps # 219 to # 221 is LE
It is output to the D lighting output port (OPLEDL to OPLEDH). Subsequent processing is equivalent to the case of the full size.
(# 208- # 210 ...). In this way, DACL is set to 8 when the imprint font for one character has been output, so the FNTOUT subroutine is exited from step # 210 and step # 103 is executed.
The font of the next character (DiGiT1) is output. The output of each subsequent character is the same as for DiGiT0, and DATSET
In the subroutine, the start address of the font of each character is set, and the font is actually output to the LED output port by calling the FNTOUT subroutine.

Here, since the last column (A7) of the font of each character contains a blank pattern for one column (in the case of DACL = H'7 or H'F), one dot blank is provided between each printed character. You will enter.

When the output to the last character (DiGiT17) has been completed, the process returns from the DATSET subroutine, waits for the wind motor 13 to stop in step # 013 in FIG. Waiting for imprinting is made (see step # 007), and one imprinting sequence ends.

Since (7 × 5) dot fonts are created from (9 × 7) dot fonts, it is necessary to select a font pattern so that there is no inconvenience in terms of shape and design as long as data is omitted and compressed using a fixed pattern. Needless to say, there is.

In this 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 15c
And single quotation mark 15e indicating year
However, in order to display English month and time, etc., the number of segments may be increased.

Corresponds to the selection means of the present invention, and the eight-channel LED driver 39 corresponds to the data recording device of the present invention.
