Abstract

PURPOSE:To form the title imprinter in such a manner that the lapse of time with each photographing frame within the same photographing date is known by imprinting the data to indicate the lapse of time at the photographing date in addition to the photographing date if the next photographing is within the same data. CONSTITUTION:An imprinting control circuit 33 starts an imprinting operation when the shutter of a camera body 47 is released and the output of an inverter 43 is increased to an H level by closing of a switch 41. The data on the month, date and year is thereby imprinted on a film plane. The display mode in a display selection circuit 9 is switched to the display mode of the date, hour and minute when the output of the circuit 33 inverts to an L level upon lapse of the prescribed time thereafter. The data on the date, hour and minute is then displayed on a display body 11. Since the output of D-FF24 does not change, the data on the date, hour and minute is imprinted at all times even if the photographing is executed any times within the same photographing date. The display mode is released only when a mode selection switch 28 is pushed again or when the film is newly loaded or when the photographing date changes.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention relates to an improvement in a data imprinting device for imprinting data such as "year, month, and day" on a film surface.

(Background of the invention) In conventional devices of this type, "year, month, day,""month, date, and time"
, "Date, Hour, Minute,"etc.; however, for example, after selecting the "Year, Month, and Day" imprint mode, the "Year, Month, and Minute" imprint modes will be used unless a new imprint mode is selected. Since the mode remains set to "Sun", if you go on a trip or take many pictures in one day,
The same data (year, month, and date) would be imprinted on all the frames, and if you tried to organize the photos after they were taken, you would not be able to tell how much time has passed, which was very inconvenient.

(Object of the Invention) An object of the present invention is to provide a data imprinting device that solves the above-mentioned problems and can indicate the chronological progress of each photographed frame within the same photographing date.

FIGS. 2(a) to (e) show five display modes that can be selected by pressing the mode selection switch 28, that is, "Year, Month, Day,""Month, Day, Year,""Day, Month, Year," and "Day, Hour, Minute." , rOF
This shows the full display (imprint) mode of FJ. Note that rOFFJ here means that nothing is displayed on the display 11.

FIG. 3 shows the output terminal D2. of the display mode counter 15. σ1
．． The output contents from DO and the corresponding display modes are shown, and the display selection circuit 9 outputs the output terminals D2. DI,
If the 3-bit signal rooOJ is output from DO, the "date, hour, minute" mode is selected, and if the 3-bit signal rooIJ is output, the "year, month, day" mode is selected.
When the 3-bit signal J is output, the "month day year" mode is output, when the 3 bit signal rollJ is output, the "day month year" mode is output, and the 3 bit signal rloOJ is output. In this case, the rOFFJ mode is assumed to be selected and the signals from each counter are processed.

Next, the operation will be explained. Every time the mode selection switch 28 is pressed, a correction pulse is generated in the display mode correction pulse generation circuit 3o, and accordingly, the display mode counter 1
5 is incremented one by one, and the output of this display mode counter 15 is rl O
When the 3-bit signal IJ is reached, the output of the AND gate 21 becomes H level (meaning a high level signal), the display mode counter 15 is cleared, and its output becomes the signal roOOJ, as shown in FIG. This results in a cycle of five display modes.

roFF is selected by pressing the mode selection switch 28.
When the J mode is selected, the output of the AND gate 22 becomes H level, and the output of the OR gate 14 becomes H level regardless of the output of the D flip-flop 24.
The output of the display mode counter 15 is directly inputted to the display selection circuit 9 via AND gates 16 to 18, that is, "
A 3-bit signal "100" is input, and in this case nothing is displayed on the display 11 as shown in FIG. 2(e).

Furthermore, when the output of the AND gate 22 becomes H level, the output of the inverter 26 is inverted to L level (meaning a low level signal), and the output of the AND gate 27 becomes L level. Even if the imprinting light source 31 is turned on until then, the transistor 32 is turned off, so the imprinting light source 31 is turned off.

Here, if the content of the hour counter 5 becomes "24" and a day pulse is generated, the day counter 6 increments by 1 and at the same time the D flip-flop 24 is cleared and its Q output becomes H level, causing an OR gate. The output from the display mode counter 15 also becomes H level, and the output from the display mode counter 15 is directly input to the display selection circuit 9.
For example, if the output of the display mode counter 15 is roloJ, the 3-bit signal ro10J will be input as is to the display selection circuit 9, and the display selection circuit 9 that receives this signal will currently be The display unit 11 via the display driver 10 assumes that the 'year' mode is selected.
A display as shown in FIG. 2(b) is displayed.

In the above state, when the shirt release is performed in the camera body 47 and the switch 41 is closed and the output of the inverter 43 becomes H level, the AND gate 27
The H level is input to the imprinting control circuit 33 via the imprinting control circuit 33, and the imprinting control circuit 33 starts the imprinting operation. As a result, the transistor 32 is turned on for a predetermined time, and during this time, the imprinting light source 31 is turned on, and data of "month, day, year" as shown in FIG. 2(b) is imprinted on a predetermined frame on the film surface. Become.

After that, when the output of the imprinting control circuit 33 is inverted to L level after a predetermined period of time has passed (this completes the imprinting operation), the D flip-flop 2
A clock is input to 4, and .

Its output is inverted to L level. When the output of this D flip-flop 24 is inverted to L level, the OR gate 14
output becomes L level (in this case, it is assumed that switch 12 is on, that is, automatic switching of the display mode is selected), and one input of all AND gates 16 to 18 becomes L level. Therefore, the input to the display selection circuit 9 is switched to a 3-bit signal rooOJ.

Therefore, the display mode in the display selection circuit 9 is automatically switched to the "date, hour, and minute" display mode, and the display 11 has a second display mode.
Data as shown in Figure (d) will be displayed.

Therefore, no matter how many times the image is taken after that, the output of the D flip-flop 24 does not change, so it always shows the "date, hour, and minute."
The data will be imprinted.

The display mode that has been automatically switched as described above is canceled when the mode selection switch 28 is pressed again, when a new film is loaded, or when the shooting date changes, etc. However, these cases will be explained below.

By pressing the mode selection switch 28 again and changing the display mode, the correction pulse generated in the display mode correction pulse generation circuit 30 is changed to the OR gate 2.
5 to the clear terminal CLR of the D flip-flop 24.
, the D flip-flop 24 is cleared, the output of the OR gate 24 is inverted to H level, and the display mode contents of the display mode counter 15 are transmitted as they are to the display selection circuit 9. The subsequent operations are the same as described above.

When a new film is loaded, the switch 44 is closed and a pulse signal is generated in the film loading pulse generation circuit 46, so the output of the OR gate 25 is inverted to H level and the D flip-flop 24 is cleared. Ru. Thereafter, the process is the same as in the case where the mode selection switch 28 is pressed again.

When the photographing date changes, a new day pulse is generated in the hour counter 5, and at the same time as the day counter 6 increments by 1, the output of the OR gate 25 is inverted to H level and the D flip-flop 24 is cleared. The subsequent operations are the same as described above.

Furthermore, when the switch 12 is turned off, that is, when automatic switching of the display mode is not selected, the output of the OR gate 14 is always at the H level, so the display selection circuit 9 receives the output from the display mode counter 15. The output is input as is, so automatic switching of display modes is no longer performed.

In the above embodiment, when many frames are taken on the same day, the display mode is automatically switched to "date, hour, minute" so that the chronological progress of each frame can be seen. As a structure that can indicate the passage of time, it is also possible to use a structure in which consecutive numbers are imprinted, and an example of a circuit structure for realizing this is shown in FIG. The same parts as in FIG. 1 are given the same reference numerals.

In FIG. 4, 50 is a numbering counter that counts the imprint number, and 51 is a numbering counter 50.
This is a display driver that decodes the output of and drives the display unit 52 that displays seven segments and two digits.

5(a) to 5(f) show the display body 1 in the embodiment of FIG.
1.52 is a diagram showing a display state, that is, a data imprinting state.

Next, the operation will be explained. When the day pulse occurs in the hour counter 5, the D flip-flop 24 is cleared and the numbering counter 50 is also cleared at the same time. At this time, the display on the display bodies 11 and 52 is in the state shown in FIG. 5(a) or FIG. 5(e). In this state, a shirt release is performed on the camera body 47 side, and a pulse is generated in the imprint control circuit 33, which turns on the imprint light source 31), and the falling edge of the pulse causes the D flip-flop 24 to be clocked. is input, its output becomes L level, and the clearing of the numbering counter 50 is canceled. Furthermore, a clock is input to the numbering counter 50 by the falling edge of the pulse generated in the imprinting control circuit 33 when the imprinting light source 31 is turned off, and the count is increased by "+1". As a result, the display on the display bodies 11 and 52 becomes the state shown in FIG. 5(b) or FIG. 5(f). From then on, each time a photograph is taken, the image shown in Figure 5 (
C),..., changes as shown in Fig. 5(d).

According to this embodiment, when many frames are taken on the same day, even if the display mode of "year, month, day" is selected, data cannot be imprinted from the second frame onwards. Since the display mode is automatically switched to "date, hour, and minute," or consecutive numbers are imprinted, it is possible to prevent the same data from being imprinted on a large number of frames and making it difficult to tell how much time has passed. It is very convenient to organize photos when you are taking a record of a trip, wedding, etc. Also, if the date changes or if a new film is loaded, the display mode will be returned to "Year, Month, and Day" immediately, so data copying of only "Date, Hour, and Minute" will not be possible. This eliminates the inconvenience of forgetting the palm and moon phases, which are necessary in such cases. Further, since a switch 12 is provided for automatically changing the display mode, one can be selected arbitrarily.

(Correspondence between the invention and the embodiments) In each of the above embodiments, the D flip-flop 24 is used as the discrimination means of the present invention, the OR gate 14, the AND gates 16-
18. The display selection circuit 9 and the numbering counter 50 serve as data automatic setting means, and the imprint light source 31. Transistor 32. Imprint control circuit 33 and display body 11.5
2 correspond to the imprinting means.

(Effects of the Invention) As explained above, according to the present invention, the discriminating means for discriminating whether or not the next photograph taken after one frame photographing is on the same photographing date, and the discriminating means determining whether the next photograph taken after one frame photographing is the same photograph. If it is a day, the data is automatically set to data that includes not only the shooting date but also the time elapsed within the shooting date. If the shooting date of the second frame and subsequent frames is on the same day, data that shows the chronological progress on that shooting date will be automatically imprinted. It becomes possible to inform the time progress of each photographed frame.
