A lens barrel according to the present disclosure includes a booster transformer that is arranged on an inner circumference side of a cam barrel and constitutes a power supply for an actuator. The booster transformer is arranged on a side surface of a barrel. The booster transformer is configured to move in an optical axis direction together with the barrel in accordance with rotation of the cam barrel.

An image capturing apparatus includes an electronic viewfinder unit that can shift between a retracted state where the electronic viewfinder unit is retracted in a main body portion of the image capturing apparatus and an extended state where the electronic viewfinder unit is extended from the main body portion. The electronic viewfinder unit includes a holding cover that holds a pivoting unit where the pivoting unit can be rotated centering on a pivot shaft, and a pivot latch member that latches in a pivoting unit pivoting operation. The pivoting unit includes an electronic display unit, an eyepiece portion, an eyepiece window to cover the eyepiece portion, and a lens holder to hold a finder lens that guides light emitted from the electronic display unit to the eyepiece portion. When the pivoting unit is being rotated, the pivot latch member regulates shifting of the electronic viewfinder unit to the retracted state.

Image capturing apparatus

An image-capturing apparatus includes a main body and a finder unit configured to transition between a retracted state and a projected state. The finder unit includes a non-rotatable portion provided with a rotation shaft, a rotatable portion that is rotatable around the rotation shaft and has an eyepiece, and a restricting member that restricts a transition from a pulled-out state to the retracted state, the eyepiece has an engaging portion and the restricting member has an engaged portion having a convex shape, the engaging portion and the engaged portion being engaged with each other in a transition between the projected state and the retracted state, and an engagement between the engaging portion and the engaged portion is released when the rotatable portion is rotated in the pulled-out state.

Image-capturing apparatus

An image capturing apparatus includes an electronic viewfinder unit configured to move between a stored state stored in a main body and a projecting state projecting from the main body, wherein the electronic viewfinder unit is held to be able to turn in the projecting state and is held not to be able to turn in the stored state.

An imaging apparatus includes a finder unit including a finder rotation unit movable between two states, a retracted state and a protruded state. The finder rotation unit is rotatably held in the protruded state.

Imaging apparatus

An electronic apparatus includes a board on which a heating element is mounted, a fan including a discharge port, a heat-exchange unit configured to receive air discharged from the discharge port of the fan and radiate heat and a heat-conductive unit configured to thermally couple the heating element and the heat-exchange unit. The heating element is placed as an extension of a discharging direction of the air from the fan with respect to the discharge port of the fan. The heat-exchange unit is placed between the heating element and the fan in a direction substantially parallel to the discharging direction.

Electronic apparatus for cooling heating element

A multipolarized signal terminal connector for an accessory, which is applied to an accessory shoe device having a defined shape. The signal terminal connector includes a first surface opposed to an attaching direction of an accessory, a first terminal row provided the first surface, a second surface which is inclined with respect to the first surface by a predetermined angle, and a second terminal row provided in the second surface. The second surface is inclined with respect to the first surface, in a predetermined direction orthogonal to the attaching direction of the accessory and a direction in which the terminals of the second terminal row are arranged, and is displaced with respect to the first surface in the predetermined direction.

A rotatable-swingable input device that has high reliability at low cost and that improves operability. Optical sensors, an elastically deformable holder, and switches are disposed on a wiring board. A shading member has a plurality of shading parts that are arranged in a circumferential direction and pass a space between a light projecting section and a light receiving section of the optical sensor when an operation member is rotated. A click spring contacts with a concavo-convex part of the operation member to generate click feeling. The holder has an inner annular part holding the operation member and shading member, and an outer annular part having pressure parts each of which deforms and pushes one of the switches when the operation member is swingingly operated. The optical sensors are arranged between the inner annular part and outer annular part without overlapping with the click spring to interpose one of the switches.

In an imaging apparatus, a first slope is formed that inclines toward a second flash-unit cam at an end face of a first flash-unit cam on the second flash-unit cam side at a first position where a flash-unit follower is located on the first cam when the flash-unit follower is engaged with the first flash-unit cam and the lens barrel unit is changed into wide angle state, and a second slope is formed that inclines toward the first flash-unit cam at an end face of the second cam on the first flash-unit cam side at a second position where the flash-unit follower is located on the second flash-unit cam when the flash-unit follower is engaged with the second flash-unit cam and the lens barrel unit is changed into a wide angle state.

The present invention discloses an image-taking apparatus which can be easily assembled. An image-taking apparatus has an image-pickup unit and an exterior member which is made of a metal and in which the image-pickup unit is inserted and contained. Here, the image-pickup unit has a projecting portion on an end face in a direction in which the image-pickup unit is inserted into the exterior member, the projecting portion projecting from the end face. The exterior member is produced by drawing and has a second opening portion in a face locating opposite to a first opening which is formed by drawing. The projecting portion projects out of the second opening portion.
