Abstract

PURPOSE:To always imprint data numerals, etc., in the easily readable direction irrespectively of the attitude of a camera with simple constitution, by concentrically arranging printing elements for data imprinting selecting the printing elements in accordance with the attitude of the camera. CONSTITUTION:Eight 7-segment printing elements 11-18 are concentrically arranged on an LCD4 and two pieces of dots 19 and 20 are provided between two pairs of the elements. When, year-month-day data, for example, December 24, 1985, are sent from a time circuit 1 as imprinting data, a switch 6 is turned off in case where the camera is in the horizontal position and a decoder 2 selects printing elements 11, 12, 17, 16, 15, and 14 and dot 19 out of the elements 11-18 and causes the LCD4 to display the data numerals through an LCD driver driving circuit 3. When a photograph is taken under this condition, a photographing control section 5 operates and a light source is turned on, then, a data image is copied. When the camera is in the vertical position, the switch 6 is turned on and printing elements 17, 18, 15, 14, 13, and 12 and dot 20 are selected, thus, vertical characters are imprinted.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application) The present invention relates to a data imprinting device for a camera.

(Prior art) In conventionally known data imprinting cameras, data numbers or characters are arranged in a line along one side of five screens so that their orientation is normal on the horizontally photographed screen. is normal.

Therefore, when a camera is held vertically to take a picture, the orientation of the image and the orientation of the data numbers are different, making it difficult to read the data and making the screen difficult to see.

In order to overcome these drawbacks, various data imprinting devices have been proposed that change the data imprinting position according to the vertical and horizontal positions of the camera so that the data is always imprinted in the correct orientation. .

However, these devices are configured to have multiple imprinting parts and select one of them according to the camera's attitude, or to move one imprinting part according to the camera's attitude, and the data It has disadvantages such as requiring a large number of parts for imprinting, having a complicated structure, and requiring a large amount of space.

(Summary of the Invention) The present invention eliminates the above-mentioned drawbacks of the conventional technology and provides a data imprinting device that has a simple configuration and allows data numbers, etc. to be imprinted in an easy-to-see direction regardless of the orientation of the camera. A plurality of printing elements constituting data numbers or characters are arranged concentrically, and printing is performed by selecting the printing element according to the attitude of the camera.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment) Fig. 1 shows a block diagram of a data imprinting device, where l is a well-known clock circuit, 2 is a decoder for decoding the signal from the clock circuit, 3 is an LCD driver, and 4 is for imprinting. 5 is a transmissive liquid crystal display (LCD), 5 is an imprint control unit, 6 is an attitude detection switch provided in the decoder 2, and a conductive fluid such as a mercury switch or a pendulum is used to detect when the camera is vertical. It is on when in position and off when in horizontal position.

Figure 2 shows the arrangement of printing elements on the LCD 4.
19. Eight printing elements 11 to 18 formed by segments are arranged equally in a concentric circle, and two screwdrivers are arranged between them.
20 is set.

Next, the operation will be explained.

First, when data for printing, for example, the date data December 24, 1985, is sent from the clock circuit 1, if the camera is in the horizontal position, the switch 6 is turned off, and the decoder 6 is turned off. 11.12.17,1 from inside the element
6, 15.14 and dot 19, the LCD is the third
Data numbers are displayed as shown in Figure (a).

When shooting in this state, the imprint control unit 5 is activated by a signal linked to the shutter release, turns on the light source for a certain period of time, illuminates the LCD, and uses the transmitted light to print the image shown in Figure 4(a) on the film. The data image is imprinted as shown.

When the camera is in the vertical position, the switch 6 is turned on,
17, 18, 15, 14, 13, 12 and 20 of the printing elements are selected, and a display as shown in FIG. 3(b) is performed.

When photographing is performed in this state, a data image is imprinted on the screen as shown in FIG. 4(b). That is, if the photograph is viewed with the image erect, the data image will be imprinted with each character erect and easy to read, just as in FIG. 4(a).

In the embodiment, an LCD was used as the display for imprinting, but it is also possible to use an LCD in exactly the same manner. It is also possible to use the above-mentioned display for external display of the camera.

Further, instead of the posture detection switch shown in the embodiment, a switch that can be manually operated depending on the posture may be used.

(Effects of the Invention) As described above, the present invention arranges the printing elements constituting the data in a concentric manner, so that it can be adjusted according to the horizontal and vertical positions of the camera while one display is fixed at the same position. It is possible to imprint data, has a simpler structure than conventional ones, takes up no extra space, and is extremely suitable for practical use.
