Abstract

(57) [Abstract] [Purpose] A person who has a certain angle from the self-timer operation display part in the system in which the self-timer also uses the light emission part of the autofocus auxiliary light of the camera as the operation display that notifies the self-timer operation. Even from the above, a self-timer operation display device capable of easily confirming the operation display of the self-timer is obtained. [Structure] The light emitting element 11 is turned on at the time of distance measurement by autofocus, and the projection light from the light emitting element 11 is converged by the condensing unit 12 to illuminate the subject. At the time of the self-timer, the light emitting element 11 blinks, and the light projected by the light emitting element 11 is converged by the condensing unit 12 to inform the center of the subject that the self timer is operating, and at the same time, the light beam diffused by the diffusing unit 13 is the subject. The self-timer operation display can be confirmed from the self-timer operation display section even at a certain angle from the self-timer operation display section.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a display device such as a camera, and more particularly to a self-timer operation display device such as a camera.

[0002]

[Prior art]

 The camera's self-timer has traditionally been a mechanical system that combines gears and power springs.In recent years, however, the camera has become more electronic, and the operation display that indicates the self-timer's operation is also indicated by an electronic sound or flashing a lamp. The method of displaying by light is the mainstream. In addition, a method has been proposed in which the light emitting portion of the autofocus auxiliary light of the camera is also used as an operation display for notifying the operation of the self-timer, especially with the autofocus of the camera.

FIG. 3 is a cross-sectional view of a self-timer in which a conventional light emitting portion for autofocus auxiliary light is also used as an operation display for informing the operation of the self-timer. Reference numeral 31 is a light emitting element such as an LED, and 32 is a condenser lens. The light emitting element 31 is turned on during distance measurement in autofocus, and the projection light emitted by the light emitting element 31 is converged by the condenser lens 32 to illuminate the subject and function as autofocus auxiliary light.

On the other hand, during the self-timer, the light emitting element 31 blinks to notify the subject side that the self-timer is operating.

[0005]

[Problems to be solved by the device]

 The autofocus auxiliary light generally has a strong directivity so that the light flux for projection does not diffuse in order to obtain an accurate focusing point even for a long-distance subject.

On the other hand, the self-timer is usually used because the photographer himself / herself becomes the subject, and is often used especially in group photos for commemorative photography. In addition, recent cameras have become capable of shooting with remote control, and their self-timers are often used.

In the case where the self-timer also uses the light emitting portion of the autofocus auxiliary light of the camera as the operation display for informing the operation of the self-timer, the self-timer operation display indicates the long-distance distance which is the original purpose of the autofocus auxiliary light. Since the directivity is strong so that the light flux for projection does not diffuse in order to obtain an accurate in-focus point even for the subject, the person who is at a certain angle from the operation display of the self-timer may There was a problem that it was difficult to see when the timer was activated and it was difficult to see when the shutter was released.

[0008]

[Means for Solving the Problems]

 In the present invention, the above-mentioned problem is solved in the system in which the light emitting portion of the autofocus auxiliary light of the camera is also used as the operation display for notifying the operation of the self-timer. The solution was to integrate a diffuser plate for diffusing auxiliary light around.

[0009]

[Action]

 By the above-mentioned means, the light ray for indicating the operation of the self-timer is diffused through the condenser lens and the directional light ray and the light diffuser installed around the condenser lens. Two types of light rays are emitted, and even a person at a certain angle from the self-timer operation display can confirm the self-timer operation, and at the same time, it functions as an auxiliary light for autofocus. Can also be used.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a sectional view of a first embodiment of a self-timer operation display device according to the present invention, in which 11 is a light emitting element such as an infrared light emitting diode, 12 is a light condensing part of the lens of the present invention, and 13 is It is a diffusing section molded so that light is diffused.

The light emitting element 11 is turned on during the distance measurement of the auto focus, and the projection light emitted by the light emitting element 11 is converged by the light condensing unit 12 to illuminate the subject and function as auto focus auxiliary light.

During the self-timer, the light emitting element 11 blinks, and the emitted light emitted by the light emitting element 11 is converged by the condensing unit 12 to notify the center of the subject that the self timer is operating and at the same time the diffusion unit The light beam diffused by 13 informs the periphery of the subject that the self-timer is operating.

As a result, even a person who emits a light ray having directivity through the condensing portion 12 and a light ray diffused through the diffusing portion 13 and having a certain angle from the operation display portion of the self-timer , It is now possible to check the operation display of the self-timer.

FIG. 2 is a cross-sectional view of a second embodiment of a self-timer operation display device according to the present invention, in which 21 is a light emitting element such as an infrared light emitting diode and 22 is a book molded to collect light. The condensing part of the lens in the invention, 23 is a diffusing part molded to diffuse light.

The light emitting element 21 is turned on during the distance measurement of the auto focus, and the projection light emitted by the light emitting element 21 is converged by the condensing unit 22 to illuminate the subject and function as the auto focus auxiliary light.

During the self-timer, the light-emitting element 21 blinks, and the light emitted by the light-emitting element 21 is converged by the condensing unit 22 to inform the central portion of the subject that the self-timer is operating, and at the same time the diffusion unit The light beam diffused by 23 informs the periphery of the subject that the self-timer is operating.

As a result, even a person who emits a light ray having directivity through the condensing portion 22 and a light ray diffused through the diffusing portion 23 and having a certain angle from the operation display portion of the self-timer , It is now possible to check the operation display of the self-timer.
