An imaging unit includes a plurality of imaging devices configured to capture images of an object; a circuit substrate configured to generate image data based on the images captured by the imaging devices; a chassis that holds the imaging devices; and a heat transfer member including a contacting portion configured to contact an installed member in a case where the imaging unit is installed on the installed member. The heat transfer member contacts the chassis or the circuit substrate, and heat conductivity of the heat transfer member is greater than the heat conductivity of the chassis.

Imaging unit including a chassis and heat transfer member

A camera body () of the present invention is provided with a concave portion (A) in which an imaging unit () including a rectangular solid shaped case () having an optical system and an imaging device is detachably disposed. When the case () is viewed from a front side in a state where the case () is disposed in the concave portion (A), the camera body () includes a back face portion (B) having a back face wall () located on the back of the case () and facing a back face of the case (), a side face portion (C) having a side face wall () facing a side face of the case (), and an upper face portion (D) having an upper face wall () facing an upper face of the case (). The concave portion (A) is defined by the back face wall (), the side face wall (), and the upper face wall (), and is open on three sides where the remaining faces of the case () are located at the time of attachment.

Body structure of imaging apparatus

An imaging apparatus comprising an imaging unit in which an optical system and an imaging device are provided, a camera body formed with a concave portion on/from which the imaging unit is mounted/removed, the imaging apparatus photographing the subject image by mounting the imaging unit on the camera body, wherein the concave portion includes three walls of a back wall portion, a side wall portion, and an upper wall portion, viewed from the subject side in a direction of an optical axis of the optical system, wherein the apparatus includes a locking member and a locking member to be locked, wherein an unlocking member for unlocking a lock of the camera body and the imaging unit by means of the locking member is disposed in an intersection portion of the side and upper wall portions, and wherein at least three wall portions which compose the concave portion, are opened.

Camera body, imaging unit mounted/removed on/from the camera body and imaging apparatus

A camera body includes a recess to which an image pickup unit is detachably attached to be placed therein. The image pickup unit includes a housing having an optical system, an image pickup device, a first connector section. The recess has three wall sections including a back wall section facing a rear of the housing of the image pickup unit and a side wall section facing a side surface of the housing when the image pickup unit is placed in the recess. The side wall section includes a second connector section to be connected to the first connector section to perform communication. The back wall section is provided with a controlling member. A rear of the image pickup unit has an insertion opening into which the controlling member is to be inserted and an abutting section to allow the controlling member to abut thereon. When the image pickup unit is attached to the recess, the first connector section and the second connector section are connected to each other when the controlling member is inserted into the insertion opening, and the first connector section is not connected to the second connector section when the controlling member abuts on the abutting section.

Camera body and image pickup unit attachable to and detachable from camera body, and imaging apparatus

A camera body to which an image pickup unit including an optical system, an image pickup device, and an image-pickup-unit connector is detachably attached, includes a recess to which the image pickup unit is freely detachably attached and which includes a back wall, an upper wall, and a side wall to be opened on a lower side, a lateral side, and a front side of the camera body. The back wall faces a rear of the image pickup unit, the upper wall is located on an upper side of the camera body in a normal use state. The camera body includes a locking mechanism to control a movement of the image pickup unit placed in the recess in a direction in which the image pickup unit moves away from the side wall, a first unlocking mechanism provided to be exposed from the camera body and configured to unlock a locked state made by the locking mechanism in response to an unlocking manipulation, and a second unlocking mechanism provided to be enclosed inside the camera body and configured to unlock the locked state made by the locking mechanism in response to an unlocking manipulation.

Camera body and imaging apparatus including an unlocking mechanism

A camera body includes a camera body connector and a recess to which an imaging unit including an optical system, an image pickup device, and an imaging unit connector is detachably attached to be placed therein. The recess includes a back wall, an upper wall, and a side wall to be opened to a lower side, a front side, and a lateral side of the camera body. The camera body has a guide mechanism to control a position of the camera body connector in relation to a position of the imaging unit connector. The imaging unit has a rear surface on which at least two guiding grooves provided to be extended between opposite edges of the imaging unit and an engagement plate section are formed. The imaging unit has a biasing member to bias the imaging unit toward the back wall. The guide mechanism has at least two guide protrusions provided on the back wall and inserted into the at least two guiding grooves and an engagement claw formed on the back wall so as to face the engagement plate section and to engage with the biasing member when the imaging unit is attached to the camera body.
