An image pickup apparatus for endoscope includes: an imager, an optical device, an optical module on which the optical device is mounted, an optical fiber optically coupled with the optical device, a ferrule having an insertion hole into which the optical fiber is inserted, and a wiring board including a first rigid board, a second rigid board and a flexible intermediate board. The ferrule is fixed to the second rigid board or a first principal surface of the optical module. A first side surface of the optical module is glued to the first rigid board, and the first principal surface is glued to the second rigid board.

Image pickup apparatus for endoscope, endoscope, and manufacturing method of image pickup apparatus for endoscope

An image pickup module includes a plurality of semiconductor devices laminated via a sealing layer a signal is transmitted via a signal cable connected to a rear surface of the image pickup module, a first semiconductor device has a semiconductor circuit portion in a central area on a first principal plane, through wires in an intermediate area and first electrodes connected to the through wires in the central area on a second principal plane, the second semiconductor device has second electrodes in the central area on a third principal plane, and an external connection terminal to which the signal cable is connected, on a rear surface, and the sealing layer includes a first sealing layer arranged in the central area and a second sealing layer disposed in an outer circumferential area surrounding the intermediate area and with a Young's modulus smaller than a Young's modulus of the first sealing layer.

Image pickup module and endoscope

There is provided an image pickup module which can be formed by a simple process while securing the mechanical strength of an inner lead at the time of bending and when fixed, without increasing an outer dimension of the image pickup module. The image pickup module includes an image pickup element having an image pickup surface, and a flexible substrate is drawn to be directed rearward of the image pickup surface. A guide member which fixes the image pickup element and the flexible substrate is provided, and the guide member includes a portion which is extended along a rear surface of the image pickup element, and a portion which is extended along a gap between the image pickup element and the flexible substrate.

Image pickup module having guide memeber for mechanical strength

There is disclosed an optical deflector comprising a mirror structure having a first and second surfaces in a front/back relation, single plate base for holding the mirror structure, and a driver for driving the mirror structure. The mirror structure comprises a pair of supports, a movable plate, and a pair of elastic members for connecting the movable plate and the supports, such that the movable plate is able to rock with respect to the supports. The movable plate has a mirror surface on the second surface. The base has an opening for exposing the mirror surface. The supports of the mirror structure are fixed to the base with the second surfaces of the supports in contact therewith. The driver includes a conductive element formed on the first surface of the movable plate, and magnetic field generating elements fixed on the base.

Optical deflector

A vibrator comprises a vibrating member and a fixing member. The vibrating member has a pair of support members, a movable plate capable of vibrating with respect to the support members, and a pair of elastic members connecting the support members to the movable plate. The fixing member holds the support members of the vibrating member. A material mainly constituting the fixing member has a larger coefficient of thermal expansion than that of a material mainly constituting the elastic members of the vibrating member.

Vibrator and manufacturing method thereof

An optical scanner has a coil and a reflection face. This optical scanner also has: a movable plate positioned at its neutral position in a stop state; torsion bars connected to the movable plate; a support body turnably supporting the movable plate by means of the torsion bars; and a restriction member disposed at a position spaced with a predetermined distance from a surface of the movable plate. The restriction member comes into physical contact with the movable plate when a shock is applied to the optical scanner. The restriction member restricts a displacement of the movable plate equal to or greater than a predetermined quantity. The movable plate is turned with the torsion bars being a turning axis.

Optical scanner

In an ultrasonic probe for use in ultrasonic endoscope, ultrasonic diagnosing apparatus and other ultrasonic apparatuses, an ultrasonic vibrator is arranged in a recess formed in a cylindrical housing and is secured thereto such that portions of first and second electrodes are exposed out of the recess. First and second lead wires are embedded in the housing such that tips of the lead wires are exposed within connecting areas formed in the housing in communication with the recess. The tips of the first and second lead wires are connected to first and second electrodes of the ultrasonic vibrator with the aid of conductive members made of solder, conductive paste or conductive adhesive agent. The other end of the first and second lead wires are extended from the same end face of the cylindrical housing.
