The present disclosure facilitates access to an imaging surface of an imaging element in an imaging apparatus in which a plurality of optical filters are selectively arranged in front of the imaging surface of the imaging element. An imaging apparatus includes an imaging element including an imaging surface on which light from a subject is incident, a first filter unit including a first optical filter, a second filter unit including a second optical filter, and a filter unit drive mechanism that drives each of the first and second filter units between a filtering position in front of the imaging surface and a retracted position deviated from the front of the imaging surface. The filter unit drive mechanism selectively executes an interlocking mode in which when one of the first and second filter units is located at the filtering position, the other of the first and second filter units is interlocked so as to be located at the retracted position, and a single motion mode in which one of the first and second filter units is maintained in a stopped state at the retracted position and the other one is driven.

An imaging apparatus includes: an imaging element including an imaging surface; a first filter unit including a first optical filter; and a drive mechanism configured to move the first filter unit in parallel in a second direction intersecting a first direction being a normal direction of the imaging surface and between a first filtering position and a first retraction position. The first filtering position is a position at which the first optical filter is present in front of the imaging surface, and the first retraction position is a position at which the first optical filter is deviated from a front of the imaging surface. The drive mechanism includes a belt member coupled to the first filter unit, and a belt drive member configured to rotate in a state where the belt member is partially wound, the belt drive member configured to move a first portion of the belt member to which the first filter unit is coupled in the second direction.

An imaging apparatus includes: an imaging element including an imaging surface on which light from a subject is incident; an imaging unit that supports the imaging element in a state where the imaging surface faces forward; a casing including a through hole in a front surface and accommodating the imaging unit in a state where a front side portion of the imaging unit passes through the through hole so as to protrude from the front surface; and an actuator that is provided in the casing and displaces the imaging unit in a direction intersecting a normal direction of the imaging surface. The imaging unit includes a flange portion extending outward from the front side portion of the imaging unit so as to cover at lease part pf a gap between the through hole of the casing and the imaging unit.

A lens hood includes: a casing provided with a through-hole; first and second rotary frames which are arranged side by side in an opening direction of the through-hole and rotate in opposite directions in conjunction with each other; and first and second lens covers which approach or separate from each other to open and close the through-hole. The first lens cover includes a first connection portion that is provided on one end side and rotatably connected to the first rotary frame, and a second connection portion that is provided on the other end side and rotatably connected to the second rotary frame. The second lens cover includes a third connection portion that is provided on one end side and rotatably connected to the second rotary frame and a fourth connection portion that is provided on the other end side and rotatably connected to the first rotary frame.

A dial device has a dial, a base member, a sphere; and a biasing member that is provided to one of the dial and the base member and biases the sphere toward the other one. An inner peripheral surface of an accommodation hole includes a portion in which a first hemispherical portion of the sphere is interposed between a first contact point and a second contact point, the first hemispherical portion of the sphere being on one side with respect to a first plane that includes the rotation direction and a biasing direction of the biasing member and passes through a center of the sphere. A recessed surface of each of a plurality of recesses includes a portion in which a second hemispherical portion of the sphere on another side with respect to the first plane is interposed between a third contact point and a fourth contact point.

In a mounting apparatus, a first spring member has an arc shape, and a second spring member is provided integrally with the first spring member or provided separately from the first spring member to be coupled to the second spring member. The second spring member is disposed inside the first spring member at a predetermined angle from the first spring member. A holding member holds the second spring member to be fitted into the holding member such that the holding member is in contact with a wearer. The configuration is able to reduce a load applied onto a head of the wearer while providing an improved fitting on the wearer.

Mounting apparatus provided with two spring members and holding member

A lens barrier unit that can further reduce the retraction space of lens barriers is provided. The lens barrier unit includes a barrier case having an opening; and multiple spherical barriers provided so as to pivot about a pivotal axis. The barriers can be shifted between a first state for closing the opening and a second state for opening the opening. In the second state, the barriers are all stored in the lower part of the barrier case.
