An image pickup unit includes an image sensor, a first circuit board on which a first land is disposed around four first side surfaces, a second circuit board on which a second land is disposed around four second side surfaces, a movement detection sensor housed in a recess of the first circuit board, and a rectangular tube bonded to the first land and the second land and sealing the recess in an airtight manner.

Image pickup unit and endoscope

An optical unit includes: an objective lens unit arranged on a distal end side; an image pickup unit arranged on a proximal end side of the objective lens unit; an optical frame; an image pickup device frame; a proximal-end-side outer circumferential face provided on a proximal end side of the optical frame; an inner circumferential face of a distal-end-side frame body provided on a distal end side of the image pickup device frame; a plurality of notches provided apart in a circumferential direction on an outer circumferential face of one of the frames, the plurality of notches having opening portions on end faces where the optical frame and the image pickup device frame face each other; and holding portions provided on an outer circumferential face of the other frame different from the one frame, the holding portions passing through the opening portions and being accommodated in the notches.

Optical unit

In a capsule endoscope, on an inside of a capsule type housing including a cylindrical main body section and two semispherical end cover sections and having a rotationally symmetrical shape with respect to a center axis of the housing, an image pickup board section, a transmission board section, and a reception board section are housed such that principal planes of the image pickup board section, the transmission board section, and the reception board section are orthogonal to the center axis. A coil wire of at least one of a transmission coil formed by a transmission coil wire and a reception coil formed by a reception coil wire, respective principal planes of which are orthogonal to the center axis, is disposed on the end cover section side of the housing.

Capsule type medical device

An image pickup unit, includes: a front group lens frame holding a front group lens; a rear group lens frame fitted to the front group lens frame and holding a rear group lens; a movable frame disposed to be movable forward and backward in a direction along a photographing optical axis within the rear group lens frame, and holding a movable lens; an adhesive bonding the front group lens frame to the rear group lens frame; and an adhesive outflow preventing portion preventing the adhesive from flowing out toward the movable frame side when the front group lens frame is bonded and fitted to the rear group lens frame.

A capsule endoscope includes a capsule type housing and a circuit board on which a plurality of board sections are arranged in a row, the circuit board being housed inside the housing in a bent state. Connection electrodes for electronic component mounting are not formed on a second principal plane of the circuit board.

An image pickup device constituted by a bare chip is mounted to a flexible substrate including an opening portion and a wiring pattern, so that a light receiving area is positioned at the opening portion and so as to be electrically connected to the wiring pattern. A rigid substrate having a concave portion capable of housing the image pickup device is connected to the flexible substrate. A bottom face of the concave portion is set as a reference face for regulating the optical axis direction of the image pickup device, and a rear face of the image pickup device is firmly fixed to the bottom face. A wiring pattern is provided on the rigid substrate, and the wiring pattern of the rigid substrate and the wiring pattern of the flexible substrate are electrically connected.

Image pickup apparatus and electronic device using the same

An image pickup apparatus having an image pickup device chip, a wiring board placed within a projection plane of the image pickup device chip and a reinforcement member fixed in abutment with at least a part of the wiring board. An endoscope having the image pickup apparatus. A method for manufacturing the image pickup apparatus.
