Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The unreleased IJ relates to a camera equipped with a data imprinting device.

(Prior art) Cameras equipped with a data imprinting device that imprints the date and time of a photograph have been known for a long time, and recently, in addition to the date, it is also possible to imprint comments such as the location and content of the photograph. The camera has already been put into practical use.

However, in order to imprint this information, a large number of imprint elements (LEDs, LCDs, etc.) are required. For example, when imprinting a date and a comment of 10 characters using a transmissive LCD, 7 segments x 6 = 42 pieces for the date, and 5 x 7 dots (1 character) x 10 = 350 pieces for the comment, a total of 392 pieces. A display segment is required. Furthermore, since all of these must be illuminated uniformly, the projection optical system such as a single mirror and lamp becomes large, and the entire apparatus becomes large and costly.

(Object and Structure of the Invention) The present invention has been made in view of the above points, and an object of the present invention is to make it possible to imprint a large amount of information onto a film with a simple structure. 1
The frame is stopped multiple times while the frame is being transferred, and predetermined data is imprinted when the film is stopped.

(Example) The present invention will be explained below based on the drawings.

FIG. 1 is a block diagram showing the circuit configuration of an embodiment of a camera equipped with a data imprinting device according to the present invention.

In the figure, l is a lamp, and 2 is a transmissive LCD (liquid crystal display) that transmits the light from lamp 1 and records data.
It is. The LCD 2 is made up of 10 5 x 7 cytomatrix cells arranged horizontally in a row behind the film, and has a total horizontal length of about 8 square meters. Depending on the voltage applied to the electrodes of LCD 2, the light transmitting portion and the light M
When the cutting section comes up, the light from the lamp 1 passes through the transparent section and data is imprinted from the back of the film. 3 is a display LCD that displays information such as dates and comments, and is provided on the back cover of the camera.

As shown in FIG. 2, the operation unit 4 is composed of a push-button mode switch 4a and switches 4b to 4d, and each time the mode switch 4a is pressed, the mode changes from imprint mode to comment correction mode to date correction mode. →The mode changes to time correction mode and l1lt. In the imprint mode, turning on the switch 4b changes the comment imprinting mode, turning on the switch 4c changes the date imprinting mode, and turning on the switch 4d changes the time imprinting mode. However, both switches 4c and 4d are not turned on at the same time, and priority is given to the switch operated after that. When the switches 4b to 4d are turned on, an on mark (ma) lights up on the display LCD 3 at a position corresponding to each switch.

Also, in the comment correction mode, when the switch 4c is turned on, an alphanumeric string (1, 2, 3, . . . -A, B) is displayed.

C) are displayed on the LCD 3 in order from the beginning, and the switch 4d
When turned on, alphanumeric strings are displayed sequentially (Z, Y
, When in the date and time correction mode, the year and time are memorized by switches 4b, 4c, and 4d, respectively.
You can adjust the month, day and hour, minutes, seconds. Note that 5 in Figure 2

Reference numeral 12 denotes a motor drive circuit for driving a motor 13 for transporting the film, and reference numeral 14 denotes an SSPS1 switch for detecting film transport.

The ssp switch 14 has contacts 14a and 14b, which are in contact with the upper end of the detection sprocket 15. A contact piece 16 is attached to two places on the upper end of the contact piece 16, and when the contacts 14a and 14b of the SSP switch 14 are positioned on the contact piece 16, the SSP switch 14 is turned on and L (L

When both are removed from the contact piece 16, the SSP switch 14 is turned off and outputs an H (High) signal to the microcomputer 9. The detection sprocket 15 has eight teeth which engage perforations in the frame F. Therefore, when the film F is fed one frame, it rotates once. During this time, the SSP switch 14 is turned on and off twice, and the microcomputer 9
detects the falling edge (HL) of the signal (SSP signal) from the SsP switch 14 and controls the feeding of the film F.

SL and S2 are switches that turn on and off when the release button is pressed, and S1 is turned on when the release button is lightly pressed down.
When the switch is turned on and pushed down further, 51 and S
Turn on both switches. Reference numeral 16 denotes a photometry circuit that detects the brightness of the subject, and 17 indicates an AF circuit that detects the distance to the subject and moves the photographic lens accordingly.

Next, the operation of the embodiment will be explained using the flowchart shown in FIG.

When the photographer presses the release button and turns on the S1 switch (F-1), the Jll optical circuit 16 and AF circuit 17
Photometry and distance measurement are performed by S (F-2), and then S
When the 2 switch is turned on (F-3), the photographing lens is driven by the AF circuit 17, and the shutter is also driven by the shutter drive circuit IO (F4), so that the a light is emitted. Thereafter, it is determined whether or not the comment imprinting mode is selected, that is, whether the switch 4b of the operation section 4 is on or not (F-5). If the comment imprinting mode is selected, the comment is read from the memory in the data imprinting circuit 7. Served (
F-6), the lamp 1 and the LCD 2 are driven and the comment is imprinted (F-7). Next, motor drive circuit 1
2 drives the motor 13 (F-8) to feed the film, the C counter provided in the microcomputer 9 is set to 1 (F-9), and the SSP subroutine is executed (F-10).

Figure 4 is a flowchart of SSPS Fusartin,
Here, falling edges of the SSP signal are detected by the value set in the C counter. That is, first, set the value of the C counter to the counter N (5-1), check whether the SSP signal or H signal is detected (S-2), and if so, proceed to the next step (S-2).
3) In (S-4), detect that the SSP signal changes from H to L and decrement the counter N.

). On the other hand, if the ssp signal is H (S-2), then L
When it changes to (S-7), decrement the counter N (5-8), and repeat until N=O (S-9~
10).

Now, returning to Figure 3, steps (F-9) and (F-1
0), the motor 13 is stopped when one falling edge of the SSP signal is detected (F-11). At this time, the film is in a state in which % frames have been transferred. Next, determine whether the date (year, month, date, time) imprint mode is selected, that is, whether switch 4c or 4d is on (F-12). If the date imprint mode is selected, the data imprint is performed. Read the year, month, day, time, or both from the clock section of the circuit 7 (F-13).

Imprinting is performed using lamp 1 and LCD 2 (F
-14). This will imprint the date and time exactly in the middle of the bottom of the shooting screen. After that, drive the motor 13 again (F-15), step (F-16)
And (F-17), the motor 13 is stopped when the falling edge of the SSP signal is detected (F-18).
, move on to the next shooting operation.

In this embodiment, by using 10 liquid crystal display sections, the film is fed intermittently twice, and independent data is printed on each screen when the film stops, thereby eliminating the need for film stoppage caused by film transport. Since positional accuracy is not required, it is effective as a simple means. Also, when imprinting data on the final frame, after shooting, the first data is imprinted at that position, and the film may be stretched before reaching the first (second) imprinting position, causing the second imprint to occur. Therefore, it is better to detect the number of films in advance by the film information detection device 18 and to perform rewinding before winding the film to the tension position. Further, the film information detecting device 18 is a film information detecting device 18
The light emitting time of the data imprinting light source 1 is controlled based on the detected O information.

As described above, if the motor is temporarily stopped during film feeding and data is imprinted, a large amount of data can be imprinted without increasing the number of imprint elements or increasing the size of the optical system.

Next, other embodiments of the present invention will be described.

In the previous embodiment, an example was shown in which data is imprinted on the long side of the photographic screen, but in this example, data is also imprinted on the short side of the photographic screen in consideration of the case where the photographic screen is taken vertically. I made it possible to include it.

The circuit configuration of this embodiment is almost the same as the block diagram of FIG. However, in this embodiment, an inverted-shaped LCD as shown in FIG. 5 is used as an element for imprinting. This LCD consists of an LCD 20 for horizontal imprinting, which imprints in the long side direction of the photographic screen, and an LCD 21, for vertical imprinting, which imprints in the short side direction of the photographic screen. LCD20 is 5
Eight x7 matrix types are arranged in the long side direction of the photographing screen, and 20 LCDs 21 are arranged in the short side direction of the photographing screen. The entire length of the photographing screen of the LCD 20 in the long side direction is equal to the interval between the perforations of the film. These LCD 21 and LCD 20 may be provided separately. In accordance with the shape of the LCDs 20 and 21, as shown in FIG. The SSP switch for detecting the transfer of is configured as shown in FIG. That is, ssp switch 25
has contacts 25a and 25b, and a circular contact piece 26a is attached to the center of the upper end surface of the detection sprocket 15, and a fan-shaped contact piece 26b is attached corresponding to each tooth of the detection sprocket 15. The circular contact piece 26a and the sector-shaped contact piece 26b are integrally formed and electrically connected, and the contact 25a of the SSP switch 25 is always in contact with the circular contact piece 26a. Therefore, when the film F is fed, the detection switch 25 is turned on and off every time the film F is fed one perforation, and this SSP signal is detected by the microcomputer 9.

As shown in FIG. 8, the operation unit 4 is additionally provided with an imprint position change switch 4e. By pressing this position change switch 4e, the printing position can be selected from horizontal, vertical 1, and vertical 2 in this order. "side"
In the mode, data is imprinted in the long side direction of the photographing screen as shown in FIG. 9(A), and the horizontal display 3a in the 1-display LCDB lights up. Also, when in "vertical" mode, the 9th
As shown in Figure (B), data is imprinted on one short side of the photographic screen, and the vertical 1 display 3b lights up in the display LCD 5 corresponding to the position where the data is imprinted. In the "vertical 2" mode, data is imprinted on the other short side of the photographing screen as shown in FIG. 9(c), and the vertical 2 display 3c lights up at the corresponding position in the display LCDa. This switching may be automatically performed by a known attitude detection means that detects the attitude of the camera body.

Next, the operation of the embodiment will be explained using the flowchart of FIG. 1O.

The operations from step (P-1) to step (P-4) are from step (F-1) to (
The operation is exactly the same as up to F-4). Next, it is determined which imprint position has been selected by the position change switch 4e of the operation unit 4 (P-5).

First, to explain the imprint position or "horizontal" mode, if it is comment imprint mode (P-6),
That is, if the switch 4b is on, the comment is read from the memory in the data imprinting circuit T (P-7).
, in the comment, the 8th character from the beginning is stored in register l in the microcomputer 9 (p-s), and the 9th to 16th characters are stored in register 2 (p-9
). Thereafter, the lamp 1 and the LCD 20 for imprinting are driven according to the contents of the register 1, and imprinting is performed (P-10). Next, the motor 13 is driven (
P-11), the C counter is set to 1 (P-12), and when the film has been wound by one perforation interval (P-13), the motor 13 stops (P-14).
). Then, the contents of register 2 are printed on LCD 20 (P-15). Since the length of L and CD 20 is equal to the reverberation interval as described above, the comments are continuously printed without being separated.

In addition, in order to keep the distance between imprinted characters at a constant distance regarding film feeding, the feeding speed of the motor 13 is adjusted to the voltage during normal feeding by a smoothing circuit in the motor drive circuit 12 using a duty ratio. By lowering the speed, the film feeding speed is slowed down and the stopping accuracy is improved. Next, the film is transferred by two perforation intervals (P-16 to P-19). Furthermore, it is determined whether or not the date imprinting mode is selected (P-20), and if so, the date is read from the clock section of the data imprinting circuit 7 (P-20).
P-21), imprint (P-22). After that, wind the film by one perforation interval (P-2
3 to 26), further determine whether it is the poetry imprinting mode (P-27), and if so, the data imprinting circuit 7
Read out the time from the clock section (P-28) and imprint it (
P-29). Finally, the film is transported four perforation controller intervals to complete film winding (
P-30 to 34). By the above imprinting operation, data is imprinted as shown in FIG. 9(a).

Next, when the "vertical" mode is selected by the position change switch 4e, as shown in FIG. ) is judged (P-35), and if the comment imprint mode is on, the comment is read (P-36), and the comment is imprinted on the LCD 21 for vertical imprinting (P-35).
-37). Then the film has a perforation interval of 1
It is rolled up into pieces (P-38 to 41).

Next, select date imprint mode (switch 4c or 4
P-42).

If it is the date imprint mode, the date (year, month, day, or time) is read out (P-43) and imprinted on the LCD 21 (P-44). Thereafter, the film is wound by seven perforation intervals (P-45 to P-48) and the next photograph is taken. In this imprinting operation, data is imprinted as shown in FIG. 9(b).

Finally, the "vertical 2" mote will be explained using FIG. 10(d). "Vertical 2" by changing the position switch 4e
mode is selected, first wind the film by five perforation intervals <p-5o~53), then if it is comment imprint mode (P-54), read out the comment (P-55) and display it on the LCD 21. Imprint (P-56) and set the film to perforation interval 1.
Roll up each piece (P-57 to 60). After that, if there is a date imprint mode (p-61), read out the date (p-62) and imprint it on the LCD 21 (p-6
3) Wind the film by two perforation intervals (P-64 to P-67) and wait for the next shot. By the above imprinting operation, data is imprinted as shown in FIG. 9(c).

Although the above-mentioned embodiment is an application of the present invention to a back-printing method (so-called data pack method), it goes without saying that the present invention is not limited to this, but can also be applied to a front-printing method.

In addition, in the embodiment, the data is imprinted while the film is being wound, but since this would slow down the shooting speed in the case of continuous shooting, a means for storing imprint data corresponding to the position of the film was provided. , this memory,
Alternatively, the stored data may be read out by detecting each frame position l when the film is rewound, and then sequentially imprinted. In addition, in the embodiment, the film is intermittently fed during winding to imprint the data, but as in the case of quick copying, the film position corresponding to the data is memorized, and the photographed frame position is detected when rewinding. The contents stored in the memory may be output and sequentially imprinted.

(Effects of the Invention) As explained above, according to the present invention, the film is stopped multiple times during the transfer of one frame, and predetermined data is imprinted when the film stops, so that the device can be A large amount of data can be imprinted on film with a simple configuration without increasing the size.
