The data imprinting device for imprinting is generally incorporated in the back cover of a camera, and includes a light emitting element (LED), which is an imprinting means arranged so as to light up in the form of numbers, and a numeral. An external display means such as a liquid crystal display (LCD) for displaying is provided.

When imprinting, LED is linked with the shooting operation of the camera
Is turned on, the setting data is imprinted on the film, and the content of the data is confirmed by the external display means before the photographing operation.

[Problems to be solved by the device]

However, in such a conventional data imprinting device, the setting data to be imprinted on the film and the setting data to be confirmed on the external display means must match, and therefore the digit number of the imprinting means and The number of digits on the external display means was matched.

However, in recent years, the necessity for increasing the functions of the data imprinting device has increased.

That is, in addition to calendar data represented by date, it is required to imprint and display various kinds of data such as the number of films taken and the exposure coefficient of the camera, and the original imprinting function such as interval mode. It is required to incorporate even functions different from.

In order to satisfy the above requirements, it is necessary to increase the number of digits of the imprinting means and increase the size of the liquid crystal display for the external display means in order to enrich the display contents.

However, the imprinting device having the above function becomes large,
Due to space limitations, it is difficult to incorporate it into the back cover of the camera, and it was not possible to satisfy all the required functions with a size that could be incorporated.

The present invention has been made in view of such conventional problems. When the imprint and external display data are small, they are externally displayed in a small space, and when the imprint and external display data are large or the data is long. In this case, it is an object of the present invention to provide a camera imprinting device in which a display area is converted as necessary to perform external display.

[Means for Solving the Problems] In order to achieve this object, the present invention comprises at least a data imprinting means for recording setting data on a film screen and an external display means for displaying the setting data. In a data imprinting device for a camera, imprinting data setting means capable of setting different kinds of data for each divided area of the external display means and simultaneously displaying the different kinds of data. 1 display control mode,
A second display that reduces or prohibits display of setting data of a desired area among the divided areas, and expands and displays setting data of another area adjacent to the desired area in the lateral direction. A control means capable of switching between the control modes is provided.

[Operation] In the data imprinting device having such a configuration, if the setting data to be imprinted and externally displayed is within the number of digits displayed on the external display means, it is displayed as it is, and if there is a large amount of setting data or data If the length is long, the display of the setting data in one of the areas of the external display means is reduced or prohibited, and the setting data in the other area adjacent to this area is expanded and displayed. Can all be displayed.

Therefore, the function of the data imprinting device can be expanded to a size that can be incorporated into the back cover of the camera without increasing the size of the liquid crystal display serving as the external display means.

[Embodiment] FIG. 1 is a rear view of a camera showing an embodiment of the present invention.

A data back 2 is attached to the back cover of the camera body 1. The data back 2 is provided with an external display LCD 3 as an external display means for confirming the data set by the photographer, and a data imprinting section such as an LED array,
A setting unit (not shown) for changing the imprinting data by an operation button or the like is provided.

The external display LCD 3 has a 12-digit 7-segment display unit 4
A plurality of symbol marks 5 composed of letters and the like are arranged, and various data are displayed by combining the 7-segment display unit 4 and the symbol marks 5.

The 12-digit 7-segment display unit 4 is basically configured to perform a display operation by dividing it into 6-digit units. For example, as shown in FIG. 1, the left 6-digit is calendar data and the right 6-digit is film number data. Like, etc., the left and right display different data.

However, the separation of the number of digits is not fixed,
For example, to display more detailed calendar data,
In addition to using the left 6 digits, some of the right 6 digits are used to display 6 or more digits.

2 (a) to (c) show the types of display forms by the 7-segment display unit 4. As shown in FIG.

FIG. 2 (c) shows the most general display form, and the left 6-digit calendar data 6c is "27th 1:39".
Is displayed, and in the right 6-digit film number data 7c, “12345
Is displayed.

If the display content of the calendar data 6c is insufficient and it is necessary to display in seconds, the film number data is not displayed by operating the data change setting unit (not shown). Operate the data change setting section to change the calendar data 6c.

As a result, in the 7-segment display section 4, as shown in FIG. 2 (a), the calendar data 6c shows "27th 1:39:24
The second film number data 7a is not displayed, that is, blank.

After displaying as described above, when the detailed display as much as the calendar data 6a is not necessary, or when the film number data is further required, the data change setting unit is operated to display `` in the calendar data 6a ''. If you remove the "seconds" display,
It returns to the basic display again as shown in FIG. 2 (c).

It is also possible to operate the data change setting section to display the calendar data in the non-display 6b and to display only the film data 7b as shown in FIG. 2 (b).

3 (a) to 3 (c) show the form of the data imprinted on the film 8 by the data imprinting section (not shown) provided on the data back 2, and FIG. This is consistent with the display forms shown in a) to (c).

That is, in FIG. 3A, the lower right corner 11a of the screen 9 of the film 8 is shown.
"27th 1:39:24" is imprinted on the screen, but since the film data is not displayed in Fig. 2 (a), the imprint space 12a between the screen 9 and the screen 10 No film data is imprinted.

On the other hand, in FIG. 3B, the calendar data is not imprinted on the lower right part 11b of the screen 9, and the film data 7b shown in FIG. 123456 ”is imprinted.

Further, in FIG. 3 (c), the calendar data shown in FIG. 2 (c) is imprinted on the lower right of the screen 9 as indicated by reference numeral 11c, and similarly, the film data is indicated by reference numeral 12c. It is imprinted.

As described above, the LCD3 for external display is
Various displays can be performed by providing a digit segment display. The LED for imprinting data is 8 digits for imprinting on the screen and 6 for imprinting outside the screen.
It is necessary to prepare a digit.

That is, the position where the data is imprinted on the film 8 is the film 8
Since the inside of the screen and the outside of the screen are separated, it is not possible to share the LED for imprinting the "second" of the calendar data, and the inside and outside of the screen are prepared.

FIG. 4 shows a circuit block for carrying out the embodiment.

The camera body 1 and the data bag 2 are electrically connected by a contact 20, and the contact 20 generates a timing signal when the camera body 1 is released.

The data bag 2 includes an operation member 22 including various operation buttons,
The CPU 21 to which the operation signal of the operation member 22 is supplied, the OED driver 23 that controls the lighting of the in-screen LED 24 and the off-screen LED 25 by the control signal generated from the CPU 21, and the LCD driver 27 that controls the external display LCD 3 are provided. .

Next, the operation of the data back 2 will be described.

When you operate the operation member 22, the operation signal corresponding to the operation button is
It is supplied to the CPU 21, and the CPU 21 transmits a control signal based on the operation signal to the LCD driver 27. As a result, the LCD 3 performs the display as shown in FIGS. 2A to 2C according to the operation of the operation member 22.

When the camera body 1 is released after the desired display is made, the timing signal (imprint signal) is transmitted to the CPU 21 via the contact 20. The CPU 21 outputs the display data (control signal) output to the LCD driver 27 to the LCD driver 23 for a certain period of time, and turns on the in-screen LED 24 and the off-screen LED 25 in correspondence with the certain period of time.

As a result, the data imprinting as shown in FIGS. 3A to 3C is performed by the in-screen LED 24 and the out-of-screen LED 25, and the above-described data imprinting and data display are performed.

FIG. 5 shows a setting data storage routine in the CPU 21.

This routine is triggered by the operation signal generated by the operation of the operation member 22 shown in FIG.

In step S1, it is determined whether or not the data set by the operating member 22 is data regarding the left 6 digits of the LCD 3 for external display. If it is determined that the data is for the left 6 digits, it is determined whether or not the data for the right 6 digits of the LCD3 that was previously set in step S2 is blank (no display). If it is blank, the left 6 digits are determined in step S3. Is set so as to require data for 8 digits.

Then, if the data for 8 digits is set, in step S4 it is set to display 8 digits by using 2 digits of the left 8 digits and the right 6 digits of the external display LCD 3 Step
At S5, the in-screen LED 24 is set to be capable of emitting light with the same data, and the storage routine ends.

On the other hand, in step S1, the operation signal is 6 on the right side of the external display LCD3.
If it is determined that it is related to the digit, it is set so that the right 6 digits of the LCD 3 are displayed in step S7, and the off-screen LED 25 is also set to emit light with the same data in step S8, and the storing routine ends. .

If it is determined in step S2 that the right 6 digits of LCD3 are not blank, and if it is further determined in step S3 that the left 6 digits do not require 8 digits of data, then in step S6 the LCD3 12 Set the required data for the digit.
Next, in step S9, both the on-screen LED 24 and the off-screen LED 25 are set to be capable of emitting light, and the storage routine is ended.

The embodiment of the present invention has been described above.
For D, 12 digits were prepared in the screen without being separated into two systems, one inside the screen and one outside the screen, as shown in Fig. 2 (a) to (c).
The imprinting similar to the display on the LCD 3 may be performed.

Further, as the imprinting member, in addition to the above configuration, a configuration in which a character pattern by LCD is illuminated by a lamp is also possible.

[Advantages of the Invention] As described above, according to the present invention, the display area of the external display means for displaying the data of the camera is divided into, for example, two areas, and different data is set and displayed for each of the distinguished areas. Configured to be able to.

Therefore, when the data display is small like in normal use, one area is used to display the data, and when there is much data to be displayed like a professional photographer or when the data is long, all of the two areas are displayed. Alternatively, desired data can be displayed by using one area and a part of the other area.

Therefore, a large amount of data can be displayed without increasing the number of digits of the LCD used as the external display means, so that the high performance imprinting device can be mounted without increasing the size of the camera. Therefore, the added value of the camera can be further improved.
