  • Patent number: 11556048
    Abstract: An electronic viewfinder unit includes a finder unit and a base member. The finder unit includes a display unit, an eyepiece portion, and a lens holding member holding a lens that guides a light flux emitted from the display unit to the eyepiece portion. The base member includes a guide member configured to guide the electronic viewfinder unit to a housed state and a protruding state. The base member includes a holding portion and a turning member. The holding portion is provided with a first holding member and a second holding member that face each other with an optical axis of the lens in between. The turning member has one end held by the first holding member and another end held by the second holding member, and is turnable about an axis orthogonal to the optical axis of the lens.

  • Patent number: 11415862
    Abstract: If vibration propagates to an operation button that is a moving member in a state where the operation button is not touched by a user, a noise is generated from near the operation button. Therefore, an electronic apparatus that reduces a noise generated from near an operation button is provided. In an electronic apparatus, a vibration device has a first vibration mode of vibrating an operation unit at a second position and a second vibration mode of vibrating an exterior member at a first position, and the operation unit is not in contact with a vibration propagation member at the first position, and the operation unit is in contact with the vibration propagation member at the second position or as the operation unit arrives at the second position.

  • Patent number: 9985399
    Abstract: An accessory shoe device enabling multi-polarization of a connector for connection to an accessory without degrading the versatility thereof. The accessory is attached to an engagement member. A signal terminal connector has contacts arranged in a lateral direction orthogonal to an attaching direction. A pair of first engagement portions in the engagement member are spaced by a first width in the lateral direction, and a pair of second engagement portions in the engagement member are spaced by a second width larger than the first width. The signal terminal connector is disposed forward of the first engagement portions in the attaching direction. A length of the signal terminal connector in the lateral direction is larger than the first width and smaller than the second width. The second engagement portions are formed rearward of the first engagement portions in the attaching direction.
