    摘要: A medium transport device includes: a first transport unit on a front side and a first transport unit on a rear side that are respectively disposed in a front part and a rear part of a region having a length in a transport direction of a medium having a transportable minimum size and that transport the medium while nipping the medium; a second transport unit that is disposed between the first transport units and that transports the medium while nipping the medium and pulling the nipped medium outward in a width direction intersecting the transport direction; and a controller that performs control so that the medium transport device transports the medium while nipping the medium by using only the second transport unit when the medium is a thin medium having a thickness less than or equal to a predetermined thickness and so that the medium transport device transports the medium while nipping the medium by using the first transport units and the second transport unit when the medium is a medium other than the thin medium.

    摘要: A distance measuring apparatus includes: plural light emitters that irradiate a target whose distance is to be measured with light and are arranged along a predetermined first direction; an optical unit that directs light so that in a case where one light emitter emits light, a light amount corresponding to a central part of the light emitter and a light amount of a boundary part with an adjacent light emitter are different and in a case where plural light emitters emit light, the light amount corresponding to the central part of the light emitter and the light amount corresponding to the boundary part are equal; a light emission control unit that controls ON and OFF of the light emitters, the light emission control unit controlling the light emitters in modes including a first lighting mode in which a combination of two or more light emitters along the first direction that is ON and a combination of two or more light emitters along the first direction that is OFF alternate, a first inversion mode in which ON and OFF are reverse to those in the first lighting mode, a second lighting mode in which a combination of two or more light emitters that is ON and a combination of two or more light emitters that is OFF alternate, the combination in the second lighting mode being shifted by at least one light emitter from the combination in the first lighting mode in the first direction, and a second inversion mode in which ON and OFF are reverse to those in the second lighting mode; and a distance measurement unit that, in a case where plural light receiving regions are provided corresponding to each of the light emitters along the first direction in a region where a light receiving unit receives light from the target, performs distance measurement on a basis of a light reception result in the first lighting mode and a light reception result in the first inversion mode in a light receiving region excluding a light receiving region corresponding to a first boundary part located at a boundary between ON and OFF in the first lighting mode, and performs distance measurement on a basis of a light reception result in the second lighting mode and a light reception result in the second inversion mode in a light receiving region excluding a light receiving region corresponding to a second boundary part located at a boundary between ON and OFF in the second lighting mode.

    摘要: An electrophotographic photoreceptor includes a base material and a photosensitive layer on the base material, in which an outermost layer constituting an outermost surface contains a total of 0.0010 ppm or greater of at least one selected from the group consisting of cyclic siloxane compounds represented by General Formulae (1), (2), (3), and (4),






    (in General Formulae (1), (2), (3), and (4), R1, R12, R13, R21, R22, R23, R24, R31, R32, R33, R34, R35, R41, R42, R43, R44, R45, and R46 each independently represent a hydrogen atom or a monovalent alkyl group that may have a substituent, Z11, Z12, Z21, Z22, Z23, Z31, Z32, Z33, Z34, Z41, Z42, Z43, Z44, and Z45 each independently represent a group represented by —Y12—X12, a hydrogen atom, or a monovalent alkyl group that may have a substituent, X11, X12, X21, X22, X31, X32, X41, and X42 each independently represent a monovalent functional group selected from the group consisting of a succinic anhydride group, a (meth)acrylic group, an alicyclic epoxy group, an amino group, a hydroxyl group, and a glycidyl group, and Y11, Y12, Y21, Y22, Y31, Y32, Y41, and Y42 each independently represent a divalent organic linking group).

    摘要: An authentication system includes an authentication server that has a first processor and authenticates a user who uses a terminal to which a login request for a network system has been transmitted, and a first terminal that has a second processor and is used by a user who is not permitted to log in to the network system, in which the first processor is configured to permit the first terminal to log in to the network system in a case where the first terminal is capable of being verified to be located in a specific space where a user who is permitted to log in to the network system is locatable in response to a login request from the first terminal.
