Abstract

PURPOSE:To make it possible to indicate numerals and characters large in size at the center of an indicator at all times within a limited display area and make full spell display of characters possible by adding a segment group connected to a common leader line to 7 segment pattern string for indicating set numerals. CONSTITUTION:An indicator 9 enabled to indicate a character string by adding excessive segments to a string of 7 segment to indicate a program mode in an indicator consisting of 7 segment that indicates shutter speed, set value of aperture, etc. is provided. That is, the indicator 9 is made by adding a pattern 'j' to fourth digit of 4 digit display of 7 segment, and adding a pattern 'ram' after that. Display similar to the former is made for display at the time of shutter preference and aperture preference, and set values are indicated in large and easily visible formation at the center of the indicator. However, at the time of program mode, display 'Program' is made in large characters at the center of the indicator as in case of shutter preference and aperture preference and easil visible display is performed.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a display device for a camera including various indicators that indicate the operating status of the camera, shooting mode or shutter speed, aperture setting value, etc., particularly a 7-segment display. The present invention relates to a display device that displays characters, numbers, etc.

[Background of the invention]

2. Description of the Related Art Conventionally, camera display devices have been devised that centrally display the camera's operating status, shooting mode, setting values, etc. on the top surface of the camera using a liquid crystal display. FIG. 6 shows an example of this type of display device. In the figure, 1 is an indicator indicating that the shooting mode is program mode, 2 and 3 are shutter priority, respectively.
There is a display indicating the aperture priority mode, and one of the modes is displayed by setting the photographing mode using an operation member (not shown). 4 is the setting value for shutter priority and aperture priority shooting, for example 1000.50 for shutter priority shooting.
Shutter setting value such as 0.1", 16 when aperture priority
．． A display consisting of 7 segments of 4 digits and a decimal point segment to display the aperture settings such as 5, 6, 1, 4, etc., and also to display the film sensitivity such as 100.400 when setting the film sensitivity. shows. Reference numeral 5 indicates an indicator indicating the cartridge past, 6 an indicator indicating whether the film has been wound completely or unfinished, 7 a display consisting of seven segments indicating a film counter, and 8 an indicator for setting the film sensitivity. 7th
8 and 9 each show an example of the display state of the display device shown in FIG. 6.

Figure 7 shows shutter speed priority, Figure 8 shows aperture priority,
FIG. 9 shows the program mode.

In Figures 7 and 8, the shutter speed and aperture value are displayed on the 7-segment display 4, respectively, but since the display 1 indicating the program mode is off, there is a blank space at the top of the display. This can easily result in a blank display format. Further, in the gramogram mode shown in FIG. 9, the seven segment display pattern on the display 4 closing the center of the screen is turned off. For this reason, the display is displayed only at the periphery, leaving the center blank, resulting in an extremely unsightly design. In the example shown in FIG. 6, display 1 indicates the program mode and display 7 indicates the set value.
Even if the position of the display device 4 made up of segments is reversed, the central portion of the display device will become blank when shutter priority or aperture priority is selected. This is unavoidable due to the nature of this type of display device, in which the display 1 indicating the program mode and the display 4 indicating the set value consisting of 7 segments are provided separately, and they do not light up at the same time. It's flawed.

[Purpose of the invention]

An object of the present invention is to eliminate the drawbacks of the above-mentioned camera display device, to be able to display both characters and numbers that do not light up at the same time, and to be large and easy to see within a limited display area. An object of the present invention is to provide a camera display device capable of forming a display/9 turns.

[Summary of the invention]

The display device for a camera according to the present invention shows the operating status of the camera,
In camera display devices that include various indicators that indicate shooting mode, shutter speed, aperture settings, etc.
It is characterized in that an extra segment is added to the 7-segment column that displays numbers such as shutter speed or aperture setting values, and a character string indicating the camera's shooting mode etc. is displayed. be.

[Embodiments of the invention]

Figure K1 shows an embodiment of the display device according to the present invention, and shows the entire display in a lit state.

In the figure, 2, 3, 4, 5, 6, 7.8 indicate the indicators indicated by the same numbers in FIG. 6, respectively. In the present invention, in order to display both the display 4, which is composed of 7 segments, which displays the shutter speed, aperture setting value, etc., and the display 1, which indicates the program mode, as shown in FIG.
It includes a display 9 that can display a character string by adding an extra segment to a 7-segment column. The illustrated display 9 has a 1 in the 4th digit of a 7-segment 4-digit display.
After that, the word ``ram'' was added.

2, 3, and 4 show display patterns of the display device of FIG. 1 in shutter priority mode, aperture priority mode, and program mode, respectively. Displays during shutter priority and aperture priority are similar to those in the conventional example shown in FIG. 6, and each set value is displayed large in the center of the display for easy viewing. A feature of the present invention is in the program mode, as shown in FIG. 4, a large "Program" display is displayed in the center of the display, similar to the display in the shutter priority mode and the aperture ahead mode, making the display easy to see.

FIG. 5 shows details of the display 9 shown in FIG.

Each 4-digit 7-segment display 9 is la-1g +2
It is composed of 7 segment lines: a-2g p 3a-3g v 4m-4g.

Since the display device of this embodiment is a liquid crystal display device, a display T-turn is formed using a transparent electrode, and a voltage is applied between it and a counter electrode pattern (not shown). The turn is configured to light up. Therefore, a predetermined display can be obtained by applying a voltage to the wiring lead line from the display pattern.

The lead lines for display segments and turns shown in FIG. 5 are 4-digit 7 segments a, b, and c, respectively.

d+@pf+g and dot point D and the node for displaying 1C"Program" in program mode! It consists of turn P. These lead lines are connected to a decoder (not shown), and a voltage is applied to the necessary lines in response to the operation of the operating member of the camera to perform display.

When priority is given to the shutter and when priority is given to the aperture, a signal having a numerical pattern is decoded by the decoder, and the numerical display as shown in FIGS. 2 and 3 is performed.

In program mode, the decoders are la and lb.

1e+1f+1g+2st2g+3c+3d+3a, 3
In order to decode g+4c, 4d, 4e, 4g and P, the display part that displayed numbers during shutter priority and aperture priority will now display the letters "Progran" in full spelling.

Furthermore, the 4-digit segment contains a single word “Jram”.
Since only the segments connected by the book drawer line are added, PROGRA of the conventional example 1 shown in FIG.
This arrangement has the advantage that the number of lead lines is the same as when independent segments called "M" are provided, and the number of lead lines does not increase despite the easy-to-read display.

〔Effect of the invention〕

As explained above, in the display device according to the present invention, full spelling of characters can be displayed by simply adding a group of segments connected to one common lead line to the 7-segment cutan array for displaying set numbers. Therefore, within the limited display area, numbers and characters can always be displayed in a large size in the center of the display, making it possible to display a display that is easy to see both in terms of design and in practical use.
