  • 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.

  • Patent number: 9927683
    Abstract: An accessory shoe device capable of improving drip-proof performance while ensuring positional accuracy in a pitch direction in which terminals of a multi-polarized signal terminal connector are arranged. The accessory shoe device includes an engagement member for having an accessory attached thereto, a signal terminal connector including terminals for connection with the accessory attached to the engagement member, a top cover having the engagement member mounted thereon, and a positioning unit for positioning the signal terminal connector with respect to the engagement member. The top cover has an opening for externally exposing the terminals of the signal terminal connector. The signal terminal connector and the engagement member are fixed to each other by the positioning unit such that they sandwich a portion of the top cover surrounding the signal terminal connector.

  • Patent number: 8743277
    Abstract: An electronic apparatus includes an operation member movable from an initial position with respect to an apparatus body, a first elastic member configured to be deformed from a first state to a second state when the operation member is moved from the initial position and to restore the operation member to the initial position with a force produced to return from the second state to the first state, a second elastic member configured to be held by the first elastic member when the first elastic member is in the first state, and a contact portion configured not to come into contact with the second elastic member when the operation member is at the initial position and to come into contact with the second elastic member when the operation member is moved from the initial position.
