Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is capable of selectively adding date-containing data or time-containing data to the same frame of a film in addition to data containing arbitrary characters. This invention relates to a data transfer device that can be imprinted.

[Conventional technology]

BACKGROUND ART Conventionally, cameras are equipped with a data transfer device that can record multiple digits (for example, six digits) of numerical values at once. The imprint mode using this data transfer device includes:
For example, there are three modes, ie, year/month/day mode, hour/minute mode, and non-imprint mode, and each mode is cyclically switched each time a switching operation is performed. The year/month/day mode is a mode in which date data is imprinted, and the hour/minute mode is a mode in which hour/minute data is imprinted. In either mode, imprinting is performed only once between completion of exposure and film feeding.

[Problem to be solved by the invention]

However, such conventional data imprinting devices cannot imprint data other than clock data (such as any combination of alpha head and numbers) and clock data onto the same frame of film.

Furthermore, it is not possible to imprint the tip data and the time and minute data on the same frame of film.

[Failure to solve the problem]

The present invention was proposed in order to solve such problems, and includes a data display means capable of displaying data including date, data including time, and data including arbitrary characters, and a means for displaying data including characters. When adding other data to this original data, the first addition that can be determined by selecting either data that includes date or data that includes time as the additional data. a second addition that uniquely determines data including time as additional data when other data is added to the original data when data including a date is used as original data; data determining means, and if additional data is added to the original data, these data are transferred to the same part of the film.
It is equipped with a data imprinting means that can be imprinted onto the pieces.

[Effect]

Therefore, according to the present invention, if data including arbitrary characters is selected as the original data and data including the date or time is selected and determined as the additional data,
Data including arbitrary characters and additional data (clock data) are imprinted onto the same frame of film.

Also, if you select data that includes the date as the original data, the data that includes the time will be uniquely determined as the additional data.
The date and time are imprinted on the same frame of film.

12f pair. Between the digits 12d and 12e, there is provided a coin segment 12g for separating hours and minutes. Year data can be displayed in digit 12a,
12b and a pair of digits 12e and 12''. digit 12a.
and 12e, there are quotation mark segments 12h and 12i to indicate the year data.
are provided for each. Monthly data can be displayed in the pair of digits 12a, 12b and the pair of digits 12C112d. At the upper right of the digits 12a and 12c, 121 is provided in the M segment 12 to indicate that the data is for the month.

Character data is displayed in digits 12b, 12d, and 12f.

These girders 12b, 12d, 12f are alpha vent and O
It has a segment structure to express the numerical value of ~9.

Display section 12j consisting of segments 12Jl and 12j2
is displayed in response to switching to the second imprint mode.

Segment 12j+ (Ft) is used when the added data is hour/minute or date/hour/minute;
jz (F c) lights up when the added data is year, month, and day.

Segment 12m displays the area number of the world time selected at that time. This area number, like the well-known world clock, is assigned to each region of the world divided by time difference. Furthermore, each region is given an abbreviation by the city or place name that represents it to make it easier to recognize, and these abbreviations are displayed in digits 12b, 12d, and 12f. Table 1 summarizes these abbreviations. The abbreviations in the table are alphabetical abbreviations of representative city and place names, and the abbreviations widely used in aviation-related fields can be used.

The segment 12n lights up when the DST mode is set, and turns off when the DST mode is released.

The imprinting device 13 is connected to 12a-12 of the external display device 12.
It has a segment corresponding to i, and it is possible to imprint an image of these onto a film.

Correction digit changeover switch 16. The correction execution switch 17 is a conventionally known data correction means, and the correction digit changeover switch 1
Each time the switch 6 is turned on, the digit to be corrected is sequentially switched, and when the correction execution switch 17 is turned on, the digit is corrected.

FIG. 3 shows the back side of this electric camera. Although not shown in this figure, the imprinting device 13 is provided inside a back cover 33 that is attached to the camera body 31 with a hinge 32 so as to be openable and closable. Below the external display device 12 is a DST switch 15. Area selection switch 14. Correction digit changeover switch 16. Modification execution switch 17. A second imprinting mode changeover switch 7 and a first imprinting mode changeover switch 6 are arranged side by side. The area changeover switch 14 has a button 14a that increases the area number each time it is turned on, and a button 14b that decreases the area number each time it is turned on. 34
is the release button. 35 is a finder observation window.

In the first imprinting mode shown in FIG. 4, which changes cyclically each time the first imprinting mode changeover switch 6 is turned on, the abbreviation mode is a mode in which the three-letter Alphabent abbreviation shown in Table 1 is displayed. It is. This abbreviation is automatically displayed according to the selected area number.

That is, for example, if the abbreviation mode is set to area number 20 in Table 1 fa) Table 1 (b), then TYO is the abbreviation and segment 12b12d,
12f. Further, when the area is subsequently switched and area number 6 is selected, NYC is displayed as an abbreviation using segments 12b and 12d12f.

The character mode is an alpha bent or any combination of up to three digits from 0 to 9.

Setting of data in this character mode can be performed by inputting the correction digit changeover switch 16 and correction execution switch 17 in the same way as the cent of normal time data. At this time, the data are A, B...y, z, etc.

...9. It changes in order like A... Setting data in this character mode is stored for each area number. For example, even if you type rJPNJ in area number 20 and type rNZLJ in area number 21, if you return to area number 20 again, rJPNJ
is displayed.

In FIG. 4, the modes other than the abbreviation mode and character mode are conventionally known, so their explanation will be omitted.

In FIG. 5, which shows the mode change when the second imprinting mode changeover switch 7 is turned on, fa) is set by the first imprinting mode changeover switch 6 immediately before the second imprinting mode changeover switch 7 is turned on. The current mode (this is called the original mode) is the date mode (Year Month Day, Month Day Year, or Day Month Year). FIG. 5B shows a case where the original mode is the date, hour, and minute mode, and FIG. In other words, according to C1 in the same figure, the date and time or the year, month, and day can be selected as data to be added to data including characters.

Next, details of the mode change in FIG. 5 will be explained using the flowchart in FIG. 6.

When the second imprint mode selector switch 7 is turned on, the second
Switch to imprint mode. The initial state in the second imprinting mode is "no data added", and the setting mode (original mode) in the first imprinting mode is set (step 601). When the half-press switch 3 is turned on in such a situation and a half-press signal is generated, this is confirmed in step 602, and the process jumps to the conventionally known imprinting process (
Step 603). That is, the data selected in the first imprinting mode is independently imprinted onto one frame of the film. If the half-press switch 3 is off in step 602, the process goes through the input processing subroutine 604, and then goes to step 60.
5 to prepare for turning on the second imprint mode changeover switch 7. In step 605, when the second imprint mode changeover switch 7 is turned on, the process proceeds to step 606, where it is determined whether the current setting mode is the date, hour, and minute mode (year, month, day, February, 9, 2013). do.

If it is determined in step 606 that the current setting mode is the date mode, the segment 12j (Ft) is turned on (step 607), the original mode is set to the date mode,
The additional mode is set to the hour and minute mode, and the date, ten hours, and minutes mode is set (step 608). External display device 12 at this time
An example of the display is shown in FIG. 7(a). This step 608
After setting the mode in , press the second imprint mode selector switch 7.
After confirming that the switch is turned off (step 609), the process proceeds to step 610. At step 610, press switch 3 halfway.
If turned on, the process advances to step 611 to perform imprint processing. The imprinting process in step 611 involves changing the display data in the imprinting device 13 from hour/minute data to date data in a time-division manner, juxtaposing these hour/minute data and date data on the same piece of film. This is done by imprinting it on the piece. At step 610, press switch 3 halfway.
is not turned on, input processing subroutine 61
2, the process proceeds to step 613, in which preparations are made to turn on the second imprint mode changeover switch 7. If the second imprinting mode changeover switch 7 is turned on in this step 613, the segment 12L (Ft) is turned off (step 614), and the second imprinting mode changeover switch 7 is confirmed to be turned off (step 614). step 615), step 60
Return to 1.

As a result, the setting mode returns to the initial mode "no data addition". That is, the mode returns to the original mode (date mode) immediately before the first imprint mode changeover switch 6 was turned on. Note that the processing from step 606 onwards is the fifth
This corresponds to the mode change shown in Figure fa).

On the other hand, if it is determined in step 606 that the current setting mode is not the date mode, the process advances to step 7 616. In step 616, it is determined whether the current setting mode is the date/hour/minute mode. If it is determined in step 616 that the current setting mode is the date, hour, and minute mode, the segment 12j2 (FC) is turned on (step 617), the original mode is set to the hour and minute mode, and the additional mode is set to the year, month, and day mode. Setting the year, month, sun, hour, and minute mode (step 61)
8). An example of the display on the external display device 12 at this time is shown in FIG.
Shown in bl. After setting the mode in step 618, it is confirmed that the second imprint mode changeover switch 7 is turned off (step 619), and the process proceeds to step 620. If the half-press switch 3 is turned on in step 620, the process advances to step 621 to perform imprint processing. The imprinting process in step 621 involves changing the display data on the imprinting device 13 from hour and minute data to year, month and day data in a time-division manner, and juxtaposing these hour and minute data and year, month and day data. This is done by imprinting on the same frame of film. If the half-press switch 3 is not turned on at step 620, the process goes through a subroutine 622 for input processing and then proceeds to step 623, in which preparation is made for turning on the second imprint mode changeover switch 7. If the second imprint mode changeover switch 7 is turned on in step 623, the segment 12JZ (FC) is turned off in step 6■4).
Check that the second imprint mode selector switch 7 is off (
Step 615), the process returns to step 601, and the setting mode is set to the initial mode (date, hour, and minute mode).

Note that the processing from step 616 described above is shown in FIG.
This corresponds to the mode change shown in b).

On the other hand, if it is determined in step 616 that the current setting mode is not the date/hour/minute mode, that is, if it is the abbreviation mode or the mode including the character mode, the process proceeds to step 624, where the segment 112L (F
c) Turn on. Then, the original mode is set to a mode that includes characters, the additional mode is set to date, and a mode that includes characters is set to a mode that includes characters (10-year-month-day mode) (step 625).

An example of the display on the external display device 12 at this time is shown in FIG. 7(C).

After setting the mode in step 625, it is confirmed that the second imprint mode changeover switch 7 is turned off (step 626), and the process proceeds to step 627. Step 627
If the half-press switch 3 is turned on at step 628, the process advances to step 628 and imprint processing is performed. The imprinting process in step 628 involves changing the display data on the imprinting device 13 from data containing characters to date data in a time-sharing manner.
Data including these characters and date data are juxtaposed and imprinted on the same frame of film. If the half-press switch 3 is not turned on at step 627, the process goes through the input processing subroutine 629 and proceeds to step 630, in which preparations are made for turning on the second imprint mode changeover switch 7. If the second imprint mode changeover switch 7 is turned on in step 630, the segment 12L (Fc) is turned off (step 631), and the segment 12j+ (Ft) is turned on (step 632). Then, the original mode is set to a mode that includes characters, the additional mode is set to a date, hour, and minute mode, and a mode that includes characters is set to a ten day, hour, and minute mode (step 633). An example of the display on the external display device 12 at this time is shown in FIG. , proceed to step 635.Step 63
If the half-press switch 3 is turned on in step 5, step 636
Proceed to and perform the imprinting process. The imprinting process in step 636 involves changing the display data in the imprinting device 13 from data including characters to date, hour, and minute data in a time-division manner, and juxtaposing the data including these characters with the date, hour, and minute data on the film. This is done by imprinting it on the same one frame. If the half-press switch 3 is not turned on in step 635, the process goes through the input processing subroutine 637 and proceeds to step 638, where the second imprint mode changeover switch 7
Be prepared for the on. Then, in this step 638, the second
If the imprint mode selector switch 7 is turned on, turn off the segment 12J+ (Ft) (step 614).
, confirm that the second imprint mode selector switch 7 is off (step 615), and return to step 601.
Set the setting mode to the initial mode (mode that includes characters in giant characters). Note that the processing from step 624 onwards is the fifth
This corresponds to the mode change shown in Figure (C).

Table 2 shows the results when the second imprint mode is set.
This is a summary of the order of data to be imprinted and the results when printed. However, it is assumed that the cartridge will be reverse loaded and the back side of the film will be exposed.

When combining the date and hours and minutes, it is natural to use Table 2, where the date is printed on the left and the hours and minutes are printed on the right. On the other hand, data that includes characters does not have this restriction, and the character data can be imprinted first.

It is assumed that the time data used in step 633 shown in FIG. 6 corresponds to the time difference of the area immediately before entering the mode including characters. Also, step 604
, 612, 622, 629637 is a procedure to be taken when there is manual power on other operating members while waiting for input, and follows the flowchart shown in FIG.

That is, when it is confirmed in step 801 that the first imprint mode changeover switch 6 is on, the setting mode, that is, the display is changed over according to the mode change loop shown in FIG. 4 (step 802). If it is not confirmed with the step knob 801 that the first imprint mode changeover switch 6 is on, or if the display change in step 802 is not made, the process advances to step 803. In step 803, it is checked whether the power switch 2 is turned on or turned off. If there is an input from the area selector switch 14 while the power switch 2 is in the on mode, the time difference is corrected and displayed accordingly (steps 804 and 805).

Also, if there is an input from the DST switch 15 in the ON mode of the power switch 2, if the daylight saving mode has already been set, it will be canceled, and if it has not been set, it will be set (steps 806 and 807). ). Also,
When the power switch 2 is in the on mode and there is an input from the correction digit changeover switch 16, a series of conventionally known data correction processes are performed (steps 808 and 809). On the other hand, if it is the power off mode in step 803, the half-press switch 3
0 on (step 81O). If the half-press switch 3 is turned on in step 810, the photometry

1).

In this embodiment, the original data and the additional data are time-divisionally imprinted onto the same frame of the film, but if the number of segments in the imprinting device 13 is increased, the original data and the additional data can be It is also possible to display the data all at once on a transmissive liquid crystal display element, and to simultaneously print these data on the same frame of the film. Further, in the present embodiment, the date, hour, and minute are exemplified as data that includes time, but data that includes seconds may also be used.

〔Effect of the invention〕

As explained above, according to the data routing device according to the present invention, if data including arbitrary characters is selected as the original data and data including the date or time is selected and determined as the additional data, the data including the characters can be selected. The data and additional data are imprinted on the same frame of the film, that is, the data other than the clock data and the clock data are imprinted on the same frame of the film, and the electric camera is compatible with world time. This will greatly contribute to the realization of the

Also, if you select data that includes the date as the original data, the data that includes the time will be uniquely determined as the additional data.
The date and time are imprinted on the same frame of the film, making it possible to display the year, month, day and hour and minute side by side.
