  • Patent number: 11962972
    Abstract: To enhance a sound image localization effect and to ensure a good viewing state in which an image or video and audio have a sense of unity. Provided is a display in which an image is displayed in a display surface, a rear cover disposed on a rear side of the display, a first speaker disposed between the display and the rear cover, and a second speaker disposed between the display and the rear cover and positioned higher than the first speaker. The second speaker outputs audio according to operation of a piezoelectric element, and has a higher audio output band than the first speaker. This enables a user to feel as if the audio is being output from the display being viewed, which enhances the sound image localization effect and ensures a good viewing state in which an image or video and audio have a sense of unity.

  • Patent number: 10801884
    Abstract: The use of a blade driving device including a first plate wherein a first opening portion is formed; a blade formed so as to enable opening/closing of the first opening portion; a driving mechanism driving the blade; and a cover, wherein a second opening portion is formed so as to essentially overlap the first opening portion, and formed so as to cover the base plate and the driving mechanism portion. Because the base plate and driving mechanism portion are covered by the cover, when compared to the conventional structure, this enables the transmission, without variability, of heat in relation to the driving mechanism portion and the base plate.

  • Patent number: 10488735
    Abstract: A focal plane shutter has a base plate with an opening; a leading and trailing blade opening and closing the opening; a leading blade driver; a trailing blade driver; a charging portion; a braking member; and a brake driver. The leading blade driver drives the leading blade through a first biasing force of a first biasing member and drives the leading blade through a second biasing force of a second biasing member. The trailing blade driver drives the trailing blade by a third biasing force of a third biasing member. The charging portion applies the second biasing force to the second biasing member and applies the third biasing force to the third biasing member. The braking member brakes the leading blade through friction and the brake driver moves the braking member to brake the leading blade, independently of the leading blade driver, the trailing blade driver, and the charging portion.

  • Patent number: 8511836
    Abstract: When a rotation member is rotated clockwise by a stepping motor, one main operation member is rotated counterclockwise through a link member and the other main operation member is rotated clockwise by said main operation member through the link member. Also, one sub operation member is rotated counterclockwise by said main operation member through the link member, and the other sub operation member is rotated clockwise by the other main operation member through the link member. This causes the amount of overlap between a main split blade mounted to said main operation member and a sub split blade mounted to said sub operation member to be increased and also causes the amount of overlap between a main split blade mounted to the other main operation member and a sub split blade mounted to the other sub operation member to be also increased. As a result, the aperture opening formed between the two main split blades is increased.

  • Patent number: 8197150
    Abstract: A first driving member for front blade that connects a front blade and a second driving member for front blade are rotatably mounted to a shaft 1g, a rear blade driving member that connects a rear blade is rotatably mounted to a shaft, the first driving member follows the second driving member and is rotated by a biasing force of a set spring in a setting operation, and is pressed by the second driving member and rotated in photography. The restraining means has a restraining member that can go in and out of an operation path of the restrained portion of the first driving member. When the present invention is adopted in a single-lens reflex camera, the restraining member can be within the operation path of the restrained portion in the setting operation for photography using an optical finder, and the restraining member can be outside the operation path of the restrained portion in the setting operation for photography using an electronic finder.

  • Patent number: 6850281
    Abstract: A focal-plane shutter for digital still cameras is constructed so that a first driving member for a first blade connected to the first blade is biased by a cocking spring to rotate clockwise and a second driving member for the first blade is biased by a driving spring to rotate counterclockwise. A driving member for a second blade connected to the second blade is biased by a driving spring to rotate counterclockwise. An exposure aperture is fully opened before photographing, and when a cocking member is rotated in a clockwise direction in photographing, the first driving member is released from the holding of the cocking member and is rotated, and the exposure aperture is covered by the first blade. After that, when releasing members are separated from the iron cores of respective electromagnets, locks of locking members are released, and the driving members are rotated counterclockwise in turn. Consequently, exposure is carried out through a slit formed by the first blade and the second blade.
