Abstract: An imaging lens may be a retrofocus type imaging optical system including, in order from an object side, a first lens group, an aperture and a second lens group. The first lens group may include, from the object side, a meniscus as a first lens in which a convex surface is formed on the object side, and a meniscus lens as a second lens in which a convex surface is formed on the object side. The second lens group may include a convex lens as a third lens, a biconvex lens as a fourth lens, a biconvex lens as a fifth lens and a sixth lens, and the fifth lens and the sixth lens may be joined to each other. The imaging lens may be constructed with 6 elements and 5 groups including the first lens group and the second lens group.

Abstract: An imaging lens unit includes a resin lens barrel and a plurality of lenses incorporated in the lens barrel. The lens barrel has a lens barrel body and a box-shaped part. A plurality of lens receiving parts are arranged at predetermined intervals in a circumferential direction of the lens barrel body and protrude from an inner peripheral surface of the lens barrel body. The fourth lens is fixed to the lens barrel in a state of being engaged with the plurality of lens receiving parts.

Abstract: An imaging lens includes a front group having negative power, an aperture stop, and a rear group having positive power, in order from an object side. In the front group, a first lens surface has a convex shape toward the object side. In the rear group, a second lens surface has a convex shape toward the object side, a third lens surface has a convex shape toward the image side, and the third lens surface has an infrared ray cut coat. A curvature radius of the second lens surface is represented by Rr, a curvature radius of the third lens surface is represented by Re, a distance from the second lens surface to the third lens surface on an optical axis is represented by Da, and the following condition is satisfied: 1.6<(Rr+|Re |)/Da<2.3.

Abstract: A trocar for inserting a surgical instrument in a body may include: a pipe including an outer cylinder relatively slidable in an axial direction, and an inner cylinder; a head located on a proximal end of the pipe; a camera that is journaled in a distal end notch of the pipe inner cylinder so as to be turnable between a deployment state in which the camera rotates to the outside of the pipe and a storage state in which the camera is stored inside the pipe; and a coil spring biasing the camera to the deployment state.

Abstract: A trocar with camera has a camera section. The camera section obtains a trocar image that includes an image of a white part on a surface of a puncture member by performing imaging when the puncture member of a trocar shaft is exposed at a deployed position. A white balance setting section for trocar image sets a white balance for the trocar image based on the image of the white part in the trocar image.

Abstract: An endoscope bonding structure includes a distal end rigid member, a tubular body, and a bonding agent. The distal end rigid member includes a first outer diameter part and a second outer diameter part. The tubular body includes a first inner diameter part and a second inner diameter part. An outer diameter of an outer periphery of the second outer diameter part decreases as a distance increases toward a proximal end side. The tubular body is fitted to an outer periphery in a state in which the tubular body is pressed to a distal end side.

Abstract: An imaging lens unit with a plurality of lenses may be incorporated in a lens barrel of resin, the lenses may include, in order from the object side, a first lens group, an aperture, and a second lens group. The first lens group may include, from the object side, a meniscus lens as a first lens with a convex surface on the object side, and a meniscus lens as a second lens with a convex surface on the object side. The second lens group may include, from the object side, a convex lens as a third lens, a biconvex lens as a fourth lens, a biconvex lens as a fifth lens, and a concave lens as a sixth lens. The first lens to the sixth lens may be incorporated in the lens barrel with a reference position between the third lens and the fourth lens.

Abstract: A trocar apparatus includes a trocar and a trocar shaft. The trocar has a retractable-type camera section and a seal unit. The seal unit has a dome type seal and a first mount. A step is formed on the proximal side of a puncture member at the distal end of the trocar shaft. A relationship between a puncture member length L1 of the puncture member and an interval L2 in the axial direction of the trocar from the boundary position between a pipe section and a head section to a first mount opening satisfies conditional formula (A) given below: L1>L2??(A).

Abstract: A trigger generating device includes: a level setting section detecting a maximum level of an audio signal in each predetermined period and setting a threshold with reference to the maximum level; and a trigger generating section comparing the audio signal and the threshold and generating a trigger signal when the level of the audio signal changes from a level smaller than the threshold to a level greater than the threshold.

Abstract: An electronic apparatus includes a main body and a panel unit removable from the main body. The electronic apparatus also includes an attachment unit in the panel unit that indirectly attaches a removable memory device to the main body through the panel unit. The main body includes a control unit that logically disconnects a data line logically connecting the removable memory device to the main body through the attachment unit, upon an operation before a power line electrically connecting the removable memory device to the main body through the attachment unit is physically disconnected.

Abstract: The present invention is equipped with a USB interface 7 for being connected to a portable music player that is an external device, a browser button 27, a rotary encoder button 26, a back button 28, CPU 31 for acquiring a content list CL from the portable music player, RAM 33 for storing the content list CL acquired by the CPU 31, and a LED processing section 42 for changing how the rotary encoder button 26 illuminates to encourage the next operation at a time when the browse button 27 is operated. Accordingly, when searching pieces of music content stored in the portable music player that is an external device, one can unknowingly understand how to operate, thereby providing good operability even for searching pieces of music content of the external portable music player.
