JPS6197637A - Device for imprinting data in camera - Google Patents

Abstract

PURPOSE:To always imprint data numerals in easily readable directions with a simple constitution, by arranging 10-segment numeral displaying units in one line and making the imprinting operation by selecting the segments in accordance with the attitude of a camera. CONSTITUTION:Ten-segment numeral displaying units 8 are arranged in one line on an LCD4. When, for example, year-month-day data are sent from a time counting circuit 1 as copying data and the camera is in the horizontal position, a switch 6 is turned off and a decoder 2 selects horizontally writing segments A-G out of the segments and causes data numerals to be displayed. When a photograph is taken under this condition, a photographing control section 5 operates and lights a light source for a fixed time so as to illuminate the LCD4, and thus, the data numerals are imprinted. When the camera is in the vertical position, the switch 6 is turned on and the seven vertically writing segments I, J, B, H, C, D, and A are selected, and thus, vertically written numerals are imprinted.

Description

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

(Prior art) In conventionally known data imprinting cameras, data numbers or characters are arranged in a line along one side of the screen so that the orientation is normal when the screen is shot in a horizontal position. 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 device depending on the vertical and horizontal positions of the camera so that data is always imprinted in the correct orientation. .

However, these devices are equipped with multiple imprint sections and select one of them depending on the camera's orientation.

It is configured to move one imprinting part according to the camera's attitude, and has drawbacks such as requiring a large number of parts to imprint data, and the structure is complex and requires a lot of space. Ta.

(Summary of the Invention) The present invention eliminates the above-mentioned drawbacks of the conventional technology and provides a data imprinting device that has an hour wheel configuration and allows data numbers to be imprinted in an easily visible direction regardless of the camera's posture. The purpose is to

Therefore, in the present invention, 3 segments are added to the conventional 7-segment number display unit to make 10 segments into one number display unit, and these are arranged in a line along one side of the screen to adjust the camera posture. Select the segment accordingly,
It is designed so that the numbers are printed in the correct direction.

With this configuration, only one set of data imprinting parts such as the liquid crystal display and the optical system need to be installed at a fixed position, and no mechanism for moving them is required, so the structure is simple and can be compared with the conventional one. It can be easily incorporated into a similar space.

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

(Embodiment) Figure 881 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 a device for imprinting. A transmission type liquid crystal display (LCD), 5 indicates an imprint control section.

Reference numeral 6 uses a posture detection switch provided in the decoder 2, a conductive fluid such as a mercury switch, or a pendulum, which is turned on when the camera is in the vertical position and turned off when the camera is in the horizontal position.

Figure 2 shows the arrangement of the number display units on the LCD 4, and the 0 display wheel position 8 is the required number of 10-segment number display units 8 as described above (eight units in the figure) arranged in a row. As shown in an enlarged view in Fig. 5, it has 3 segments H9I and J added to the conventionally well-known 7 segments) When shooting in a vertical position, horizontally written numbers and vertically written numbers can be switched by forming numbers using the 7 segments of IJBHCDA.

Next, the operation will be explained.

First, the data for imprinting, for example, date data 8
When December 25, 2015 is sent from the clock circuit, if the camera is in the horizontal position, the switch is turned off, and the decoder 2 reads the horizontal writing portions A, B, C, from among the segments. Select D, F, FG, Figure 3 (a)
Display data numbers like this.

When shooting in this state, the imprint control unit 5 is activated by a signal linked to the shirt release, turns on the light source for a certain period of time, irradiates the LCD, and uses the transmitted light to print on the film as shown in Figure 4 (a). ), horizontally written data numbers are imprinted along the screen.

When the camera is in the vertical position, the switch 6 is turned on,
7 segments I, J, vertical writing part in the segment
B, H, C, D, and A are selected and a display as shown in FIG. 3(b) is performed.

When a photograph is taken in this state, data numbers are written vertically along the sides of the screen as shown in FIG. 4(b). In the embodiment, an LCD is used as the display for imprinting, but an LED can also be used to achieve the same configuration. 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 numerical display units formed of 10 segments in a line, and out of the 10 segments, 7 segments are for horizontal writing and 7 segments are for vertical writing. Data imprinting allows easy-to-read data numbers that match the orientation of one screen to be recorded without the need for multiple displays or movement mechanisms for display units as in the past. A device is obtained.
