Abstract

PURPOSE:To easily judge whether a camera is in an action-feasible state or in an action-inhibiting state by displaying whether the camera is in the action- feasible state or in the action-inhibiting state when a set means is in the action- feasible state or the action-inhibiting state. CONSTITUTION:When a mode selector 3 is set to OFF and a switch is closed, a power source save state is attained and the current of a battery is supplied to only a clock and a liquid crystal display device 1. Then, a data is displayed by the display device 1. At this time, the respective pointers of the display parts 2a-2d of a rotary pointer type display device 2 are set at prescribed positions and they show that the camera is in the action-inhibiting state. When the camera is set in the action state by setting the selector 3 to one mode out of the photographing modes P, A and T and closing the switch, the display of the display device 1 is switched to the counter display from the data display. Besides, the number of exposed frames of a film is displayed. Simultaneously, the rotary pointer of the counter 2c of the display device 2 is driven and the number of exposed frames is displayed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for a camera.

[0002]

2. Description of the Related Art The applicant of the present invention displays a counter indicating the number of shots of film when the power switch of the camera is on and a date indicating the date when the power switch is off. We have proposed a display device for such a camera.

However, in such a camera display device, since the date is displayed even when the power switch is off, the camera is in a state capable of performing a photographing operation (hereinafter
It is in the ready state) or the camera is prohibited from shooting (hereinafter called the disabled state)
There is a problem that it is difficult to judge whether it is in.

An object of the present invention is to provide a display device for a camera, which can easily determine whether the camera is in an operable state or an inoperable state.

[0005]

The present invention will be described with reference to FIG. 1 showing an embodiment. The invention of claim 1 has a setting means 3 for setting a camera in an operable state or an operation prohibited state. The first display unit 1 and the setting unit 3, which are used in a camera and are applied to a display unit of a camera that displays various information, operate regardless of whether the setting unit 3 is in an operable state or an operation prohibited state. The second display means 2 is provided which is activated when set in the operable state and is inhibited when the setting means 3 is set in the operation prohibited state, thereby achieving the above object. In addition, claim 2
The display device of the camera displays that the camera is in the operable state by the second display means 2 when the setting means 3 is set in the operable state, and the setting means 3 is set in the inoperable state. When it is turned on, it indicates that the camera is in the inoperable state. The display device for a camera according to claim 3 comprises a first display means 1 and a second display means 2.
Are installed on the same surface of the camera or at positions where both can be viewed at the same time. The first display means 1 of the display device for a camera according to claim 4 is a mechanical display means, and the second display means 2 is a mechanical display means.

[0006]

The first display means 1 operates to display various kinds of information regardless of whether the camera is set to the operable state or the inoperable state. On the other hand, the second display means displays that the camera is in the operable state when the setting means 3 is set in the operable state, and activates the camera when the setting means 3 is set in the inoperable state. Display that the status is prohibited. This makes it possible to easily determine whether the camera is in the operable state or the inoperable state.

Incidentally, in the section of means and action for solving the above-mentioned problems for explaining the constitution of the present invention, the drawings of the embodiments are used in order to make the present invention easy to understand. It is not limited to.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a top view of a camera equipped with a display device of one embodiment, and FIG. 2 is a block diagram showing the configuration of one embodiment. The liquid crystal display 1 displays, for example, “year, month, day” according to the date information obtained from the clock 6. Rotating pointer type display 2
Is composed of a distance display section 2a showing a shooting distance, an aperture display section 2b showing an aperture, a counter 2c showing the number of shots, and an exposure correction display section 2d showing an exposure correction value, and an index for each display section. A rotation pointer, a stepping motor (not shown) for driving the rotation pointer, and a stepping motor drive circuit. The mode selector 3 is a switch for switching between an OFF mode for prohibiting the operation of the camera and various shooting modes P, A, T.

The switch 3a is a switch interlocking with the mode selector 3, and is closed when the mode selector 3 is set to any one of the photographing modes P, A, and T, and when the mode selector 3 is set to OFF. Open circuit.
The switches 4a and 4b are switches that interlock with the release button 4, and the switch 4a is closed when the release button 4 is half pressed, and the switch 4b is closed when the release button 4 is fully pressed.

The control circuit 5 controls the liquid crystal display 1 and the rotary pointer type display 2 according to the operation of the mode selector 3 and the release button 4. When the mode selector 3 is set to OFF and the switch 3a is opened, the control circuit 5 enters a power-saving state, supplies the power of the battery 7 only to the clock 6 and the liquid crystal display 1, and displays the liquid crystal as shown in FIG. Display the date on the device 1. At this time, the pointers of the respective display portions 2a, 2b, 2c, 2d of the rotary pointer type display 2 are set to their respective predetermined home positions, indicating that the camera is in the operation prohibited state.

The mode selector 3 controls the shooting modes P, A,
When any one of T is set and the switch 3a is closed to enable the camera, the control circuit 5 switches the liquid crystal display 1 from the date display to the counter display as shown in FIG. In addition to displaying the number of captured images, the rotation pointer of the counter 2c of the rotary pointer type display 2 is driven to display the number of captured images.

The mode selector 3 controls the shooting modes P, A,
When the release button 4 is half-depressed in the state of being set to either T, the switch 4a is closed and the control circuit 5
As shown in FIG. 4, the rotation pointer of the distance display unit 2a of the rotation pointer type display 2 is driven according to the distance measurement result of the distance measurement device (not shown) to display the photographing distance and the photometry of the light measurement device (not shown). The rotation pointer of the aperture display unit 2b is driven according to the result, and the aperture value determined based on the photometric result is displayed.

The information displayed on each display is not limited to the above embodiment.

In the configuration of the above embodiment, the liquid crystal display 1 constitutes the first display means, the rotary pointer type display 2 constitutes the second display means, and the mode selector 3 constitutes the setting means.

[0015]

As described above, according to the present invention, regardless of whether the camera is set to the operable state or the inoperable state, the first display means is operated to display various information and set. When the means 3 is set to the operable state, the second display means indicates that the camera is in the operable state, and when the setting means 3 is set to the inoperable state, the camera is displayed on the second display means. Since it is displayed that the camera is in the inoperable state, it can be easily determined whether the camera is in the inoperable state or in the inoperable state.
