A movable optical unit configured to be rotatable around an axis by an electromagnet includes a fixed shaft, a bearing through which the fixed shaft is inserted and which is polarized in a direction orthogonal to a long axis of the fixed shaft, a holding frame that is provided to be rotatable around the fixed shaft and holds at least one optical member, and a pair of arm members extending outward from the holding frame in a direction orthogonal to the long axis of the fixed shaft, the pair of arm members being bonded to the bearing in a state of sandwiching the bearing in a direction along the long axis of the fixed shaft.

Movable optical unit, optical adapter, and endoscope apparatus

An endoscope apparatus includes a first optical system, a second optical system, a light-blocking shutter, a magnet rotor, drive coils, detection coils, and a CPU, the CPU performs control to provide direct current to the drive coils and control to provide alternating current to the detection coils, and where the alternating current is provided to the detection coils, the CPU detects a pivotal position of the light-blocking shutter by detecting variation of an inductance when a magnetic field generated in each of hollow portions of the detection coils is blocked by a magnetic body, from a value of the alternating current.

Endoscope apparatus

An imaging mechanism and an endoscope apparatus include: an image sensor including a sensor face and a plurality of input/output leads, a holding member having a sensor contact face, a circuit board that is secured to an outer face of an opposite side of the holding member to the sensor contact face, and a contact-point part disposed on a side face of the circuit board intersecting with a mount face, and in a region where the outline of the circuit board is inside the outline of the holding member. At least one of the holding member and the circuit board includes a relay wiring part which the contact-point part and at least one of the input/output leads are electrically connected to.

Imaging mechanism and endoscope apparatus

An endoscope adapter including a light emitting diode includes: a detachable portion to be attached to an adapter attaching portion provided on a distal end portion of an insertion portion, the insertion portion including inside thereof at least one image-forming optical system; an adapter main body including an adapter side observation optical system whose optical axis is coincident with an optical axis of the image-forming optical system; a contact pin which enables power supply to the light emitting diode to be turned on when the detachable portion is attached to the adapter attaching portion; and a resistor arranged in a space formed in the endoscope adapter to determine a type of the endoscope adapter.

Endoscope adapter including light emitting diode, and adapter type endoscope

An electrical connection portion fixed to an apparatus main body includes a plurality of conductive members and an insulating portion for electrically insulating the conductive members from the apparatus main body in which the conductive members are arranged. The insulating portion covers the circumference of the plurality of conductive members. Further, the insulating portion makes the conductive members arranged side by side in a state where the conductive members are insulated from each other.
