Abstract: A first lens group unit 20 includes a lens L2, a blacked-out portion L2b, a lens frame 22, and an injection hole 21a. The lens L2 has a thrust surface L2d that intersects the direction of the optical axis AX, a thrust surface L2c on the opposite side from the thrust surface L2d, and an edge surface L2e that connects the thrust surface L2d and the thrust surface L2c. The blacked-out portion L2b is provided to an edge surface L2e of the lens L2, and suppresses the reflection of light incident on the lens L2 on the edge surface L2e. The lens frame 22 has a substantially cylindrical shape, and holds the lens L2, which is inserted from the thrust surface L2d side along the cylindrical inner peripheral surface 22a. The injection hole 21a is used to bond the lens L2 and the lens frame 22 with an adhesive applied to the thrust surface L2c.

Abstract: An optical device actuator comprises a movable frame (33) including a focus lens (L11); a main shaft guide (40); a piezoelectric element (36a); a weight (36b); a fixed frame (30); a guide holding frame (35); and a spring (36c). The piezoelectric element (36a) imparts vibration to a first end (40a) side of the main shaft guide (40). The fixed frame (30) supports the piezoelectric element (36a) and the weight (36b) disposed on the first end (40a) side of the main shaft guide (40). The guide holding frame (35) supports, in a fixed state, the main shaft guide (40) on a second end (40b) side on the opposite side from the first end (40a) side. The spring (36c) is provided on the first end (40a) side of the main shaft guide (40), and presses the piezoelectric element (36a) along the axial direction with respect to the first end (40a) of the main shaft guide (40) via the weight (36b).

Abstract: A purification unit includes a first electric conductor and a second electric conductor that contacts the first electric conductor. The first electric conductor includes a junction composed of a contact surface with the second electric conductor and an electronic connection section that conducts electrons from the junction to a catalyst. The second electric conductor includes a junction composed of a contact surface with the first electric conductor and an electronic connection section that conducts electrons, which moves from microorganisms to the second electric conductor, to the junction. The electronic connection section of the first electric conductor has higher electrical resistivity than the junction of the first electric conductor, and/or the electronic connection section of the second electric conductor has higher electrical resistivity than the junction of the second electric conductor. The first electric conductor contacts a gas phase including oxygen, and the second electric conductor contacts a treatment target.

Abstract: A lens barrel includes: a fixed frame; a cam frame rotating with respect to the fixed frame; and a lens frame moving in conjunction with the rotation straight forward along the fixed frame. The fixed frame has a pair of first groove portions penetrating the fixed frame and extending substantially parallel with an optical axis. The lens frame includes: a first cam pin projecting from one of the first groove portions, and engages with the cam frame; a pair of straight keys guided by the pair of first groove portions; and an urging portion urging the first cam pin in the projecting direction. The first cam pin is only on one of the pair of straight keys. The pair of first groove portions are opposed to each other in the urging direction of the first cam pin with the optical axis interposed between the pair of first groove portions.

Abstract: A lens barrel 10 comprises a fourth lens group unit 20, cam pins 22a and 22b, a biasing pin 23, a cutout portion C1, a substantially cylindrical first lens group unit 13, and a plurality of rectilinear guide portions 25. The fourth lens group unit 20 has a substantially cylindrical main body portion 21 that holds a lens L4a, etc. The cam pins 22a and 22b are provided to the fourth lens group unit 20, protrude in the radial direction, and engage in the cam grooves 14b of the cam frame 14. The biasing pin 23 is provided to the fourth lens group unit 20, is supported so as to bias in the radial direction, and engages in the cam groove 14b. The cutout portion C1 is formed by cutting out the portion of the main body portion 21 of the fourth lens group unit 20 opposite the biasing pin 23 in the direction of the optical axis. The main body portion 21 of the fourth lens group unit 20 is provided continuously in the circumferential direction, from the biasing pin 23 to the cam pins 22a and 22b.
