Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a data imprinting device for a camera used to imprint data such as a date on the surface of a film.

Conventional technology Conventional camera data imprinting devices were normally configured to imprint erect data on the lower edge of the film surface in the horizontal direction, so in vertically elongated photographs, the text would be tilted sideways, making it unnatural and difficult to read. The downside was that it was difficult.

Problems to be Solved by the Invention In this invention, in response to switching between landscape and portrait photography, data expressed in two-digit numbers, such as the date, is displayed horizontally using a segment display member consisting of a small number of display segments. It is an object of the present invention to provide a data imprinting device that can imprint data in a vertical or vertical display, makes it easier to read data in a photograph, and can be manufactured at low cost.

Means for Solving the Problems In order to achieve the above object, the data imprinting device according to the present invention includes a data imprinting direction switching member 35 and a data imprinting direction switching member 35.
In order to make it possible to switch between horizontal or vertical display of data numbers according to the operation of 5, four light-emitting segments 78 form a quadrilateral, two in the vertical direction and two in the horizontal direction, in which four sides are formed. The segment display members 4 are arranged side by side to form one set of number display unit parts 77.
Configure 0.

Next, the operation of this invention will be explained. Due to the operation of the data imprinting direction switching member 35, one number, which was formed by a quadrilateral made up of two vertically aligned segments 78, is now formed by a quadrilateral made by two horizontally aligned segments 78. .

Embodiment FIG. 1 is a sectional view of a camera having a focal plane shutter (not shown) taken in a direction parallel to the optical axis. In this embodiment, the camera is a fixed focus camera. The block-shaped unit member 10' constitutes a lens receiving portion, a mirror holding portion, and the like. A lens system 12 is provided in the lens receiving portion. In order to reflect the photographing light transmitted through the lens system 12 by 90 degrees and form an image on the focal plane 76, a reflecting mirror 13 is fixed to the mirror holder at an angle of 45 degrees with respect to the optical axis of the lens system. There is. On the other hand, a segment display member 40 is provided at the bottom of the photographic lens to display luminous numbers in order to imprint data. A projection lens 14 and mirrors 33', 16 are arranged in the optical path of this data-imprinting light, so that the data-imprinting light is imaged on the data-imprinting portion 23 on the focal plane 76. However, in this embodiment, when performing data imprinting, the image of the subject to be imaged on the data imprinting section 23 is differentially focused, so that the data can be clearly identified. Therefore, the portion of the reflecting mirror 13 corresponding to the data imprinting portion is raised above the reflecting surface to form a convex portion 19, and the subject image is defocused. Further, when data imprinting is not necessary, a data image is not formed, and the convex surface portion 19 is made flush with the reflecting surface of the reflecting mirror, so that the subject image is clearly formed.

In this embodiment, the data imprinting device is configured as follows in order to imprint data in horizontal writing or vertical writing in accordance with portrait or landscape photography.

First, the segment display member 40 is configured as shown in FIG. 2A. In other words, the center line of the conventional 7-segment for numerical display is now the center 2 line,
Two quadrilaterals made up of four display segments 78 are provided vertically adjacent to each other to form a unit for displaying one digit in the horizontal position, and two of the above quadrilaterals are also horizontally adjacent. It is provided as one unit for displaying one digit in the vertical position. In this way, a total of four adjacent quadrilaterals, two in the vertical and horizontal directions, form a set of number display units 77, and one unit of two-digit numbers is displayed in the vertical or horizontal position. In addition, several sets of these are arranged side by side so that, for example, a combination of year, month, and day can be displayed. for example
If December 30, 1979 (Showa 54) is displayed horizontally, it will look like Figure 2B, and if it is displayed vertically, it will look like this:
It will look like Figure 2C.

On the other hand, a switching operation member 35 that can be operated from outside the camera is provided, and by manually moving it, the switching contact piece 36 of the switching switch member 36
The right contact piece 7 is used to change the switch by operating a to display the signal input to the segment display member 78 in the form of two upper and lower quadrilaterals for displaying one digit unit.
9 or the left tangent piece 80 for display with two left and right quadrilaterals to determine vertical or horizontal display. Note that this changeover switch member 36
However, for example, it is also possible to automatically switch by using a mercury switch element that moves in conjunction with the movement of the camera body from a horizontal shooting position to a vertical shooting position. When there is both a shutter button for horizontal shooting and a shutter button for vertical shooting, when the shutter button for horizontal shooting is pressed half a stroke, the horizontal position data is imprinted, and the shutter button for vertical shooting is When the shutter button is pressed down by a half stroke, the vertical position data may be imprinted, and with this configuration, there is no need to check or manually operate the switching operation member 35 each time.

In order to make the convex portion 19 flush with the reflecting surface of the reflecting mirror 13 when data is not imprinted, the data imprinting device according to this embodiment has the following features:
It is structured as follows. In order to disable the data imprinting device, when the switching operation member 35 is further moved to the left in FIG. It comes into contact with the pin 37a and pushes the holding member 37 to the left against a biasing force (not shown). For this reason,
An operating member 39 pivotally connected to the unit member 10' by a shaft 38 is attached to a branch arm 37b of the holding member 37.
It is released from being pushed to the right, and rotates counterclockwise following the branch arm 37b due to the biasing force of the biasing spring 42. The convex portion 19 having the pin 19a fitted into the slit groove 39a formed in the head of the operating member 39 has a top reflective surface 19b protruding from the mirror surface of the reflecting mirror 13. It moves until it is regulated by the regulating surface 10g of the unit member 10' so that it is in a plane with the mirror surface. At the same time, the data switch member 43 is moved from the closed state in which the contact piece 43a is pressed by the holding member 37 to the leftward movement of the holding member 37, and becomes released. Therefore, the segment display member 40 does not light up and no data is imprinted. Then, since the non-imaging state of the subject in the data imprinting section 23 is released, normal photographing is performed on the entire surface of the photographing screen section 24.

Effects of the Invention According to the above-mentioned invention, data numbers can be displayed vertically or horizontally depending on whether the photograph is taken in the vertical or horizontal direction, so that the image can be displayed naturally even when photographing in either direction. It is possible to provide a data imprinting device that can display data that is easier to read. In addition, this device enables horizontal and vertical display of data represented by two-digit numbers using 16 segments as a display unit, making it possible to provide a data imprinting device at a low cost. .
