Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photographic data viewing device for a camera equipped with a data imprinting mechanism for imprinting data such as dates, numbers, symbols, etc. onto a film, and is intended to prevent erroneous operation of the camera.

Furthermore, the present invention provides a camera in which a battery check can be easily performed by adding a simple configuration to a captured data viewing device of a camera equipped with a data imprinting mechanism.

Conventionally, in cameras equipped with a data imprinting mechanism, the operation knob that opens and closes the data viewing section to check whether the necessary shooting data has been set and the switch for the data imprinting circuit have been configured separately and independently. . Therefore, even if the photographer operates the data setting dial etc. to set the necessary data and confirms the setting data on the data viewing section, he or she forgets to turn on the data imprinting circuit and the data necessary for shooting is lost. However, there were drawbacks such as the fact that the images were not photographed, leading to serious consequences.

The present invention is configured such that the power switch of the data imprinting circuit is linked with an operation knob that opens and closes a data viewing section that visually checks whether necessary data has been set in the camera by operating a data setting dial or the like. When data is displayed on the data viewing section by operating the operation knob, the power switch is automatically closed; when no data is displayed on the data viewing section, the power switch is left open. This solves the above-mentioned conventional drawbacks and prevents erroneous operation of the camera.

Furthermore, an object of the present invention is to make it possible to easily perform a battery check by interlocking the operation knob of the data viewing section with a switch of the battery check circuit, and to minimize the energy consumption due to the battery check. do.

The present invention will be explained below with reference to the drawings.

FIG. 1 is a sectional view of a main part of a photographed data visual recognition device according to the present invention. FIG. 2 shows an enlarged perspective view of the main parts of the data viewing section.

In the figure, 1 shown with diagonal lines is the camera body, 2
is a data display drum of a data imprinting mechanism, and has a character tape 4 on its outer periphery on which data such as dates, numbers, symbols, etc. are displayed. Data display drum 2
is supported on the camera body by a shaft (not shown), and setting operations are performed using a data setting dial (not shown). 6 is an upper cover fixed to the camera body 1; 8 is a convex lens that constitutes the data viewing section.

10 is a convex lens 8 with the operation knob of the data viewing section.
The convex lens 8 can be moved left and right by moving the operating knob 10 left and right. Reference numerals 12 ₁ and 12 ₂ are openings provided in the upper cover 6 for displaying photographic data, data off, and battery check, through which photographing data, data off, and battery check are displayed through the convex lens 8 by operating the operation knob 10.
Display the data off indication respectively. Reference numeral 14 is a transparent part such as glass, which is connected to the convex lens. 16
is a sliding plate for opening and closing the power switch of the data imprinting circuit, which includes a lens section 8, an operation knob 10, and a transparent plate 14.
It can also be formed integrally with. The sliding plate 16 slides along the upper cover as the operating knob 10 is moved in the left-right direction. By sliding the sliding plate 16 in the left-right direction, parts appearing in the openings 12 ₁ and 12 ₂ are rendered opaque. 16a is a groove provided in the sliding plate 16. 16b is a switching member provided on the sliding plate 16 for opening and closing the switch. 16c is a notch provided in the sliding plate 16. 18 is a notch provided in the camera body 1. 20
The sliding plate 1 is moved by a click spring provided in the notch 18.
By moving left and right 6, the groove 16a and the notch 18 are clicked.

22 is a display board with "DETE・OFF" displayed on its surface. 24 is a display board with "BATTELY・CHECK" displayed on the surface. The display plates 22 and 24 are fixed to the camera body. Reference numerals 26 and 28 are contacts of a power switch connected to a data imprinting circuit (not shown), which are fixed to the camera body through an insulating plate (not shown).

The contact pieces 26 and 28 are the switching member 16 provided on the sliding plate.
b allows for contact conduction.

Reference numerals 30 and 32 are contacts of a battery check switch connected to a battery check circuit (not shown), and are fixed to the camera body through an insulating plate (not shown). The free end 30a of the contact piece 30 is configured to contact and conduct with the contact piece 32 by moving the sliding plate 16 in the left direction, and the free end of the contact piece 30 has a spring force in the direction of opening the switch. ing. In the state shown in FIG. 1, the data on the data display drum 2 is visible through the transparent portion 14 and the convex lens 8. In this state, the contact pieces 26 and 28 of the power switch of the data imprinting circuit are pressed by the switching member 16b and brought into contact with the contact piece 28 to operate the data imprinting circuit.

Figure 3 is a plan view of Figure 1 and shows the data display drum 2.
The above data is visible. Next, operation knob 10
When the sliding plate 16 is moved to the right, the click spring 20 falls into the groove 16a and fixes the sliding plate as shown in FIG. 4. In this state,
The position of the data viewing section is shifted from the data display drum 2, and the "DETE/OFF" signal on the display board 22 is visible to the data viewing section through the transparent section 14 and the convex lens 8. In this case, the contacts 26 and 28 of the power switch of the data imprinting circuit are connected to the switching member 16.
Since the pressure on b is released, the data imprinting circuit is not closed and no data is imprinted even if the camera is operated.

FIG. 5 is a plan view of FIG. 4, showing a state in which "DETE/OFF" is visible through the transparent part/convex lens. Next, the case of battery check will be explained. As shown in FIG. 6, when the operating knob 10 is moved to the left and moved to a position where "BATTELY CHECK" is displayed on the display board 24 through the convex lens 8, the left end of the sliding board 16 is the power switch for the battery check circuit. The contact pieces 30 and 32 come into contact with the free end 30a of the contact piece, thereby closing a battery check circuit (not shown).

Since the contact piece 30 has a spring force in the switch opening direction, it generates a force to slide the sliding plate 18 in the right direction in the position shown in FIG. 6, and when the operating knob 10 is released, the contact piece 30 and 32 break contact. Therefore,
To operate the battery check circuit when checking the battery, press the operating knob to the left and press the convex lens 8.
This is only when the "BATTELY・CHECK" display is visible through the Figure 7 shows operation knob 10.
Push to the left and select "BATTELY・CHECK"
Indicates a state in which the display is visible.

As described above, in the present invention, the operation knob of the data viewing section and the power switch of the data imprinting circuit are configured in an interlocking relationship, so that when photographic data is displayed, the data imprinting circuit is automatically activated. "DETE・
When "OFF" is visually confirmed, the data imprinting circuit is disconnected, which prevents operational errors during data imprinting photography.

Furthermore, since the battery check circuit is configured to be openable and closed in conjunction with the operation of the operating knob 10, the battery check operation of the camera can be simplified. Furthermore, this is an extremely excellent invention in which the energy consumption required for battery check can be kept to a minimum due to the effective structure of the sliding plate 16 that interlocks with the operating knob 10 and the switch contact piece of the battery check circuit.
