A foamer mechanism () of a foam dispensing container has a gas-liquid contact chamber (), a liquid agent flow passage () through which a liquid agent supplied from a liquid agent supply portion () to the gas-liquid contact chamber () passes, and a gas flow passage () through which a gas supplied from a gas supply portion () to the gas-liquid contact chamber () passes. The gas flow passage () has a gas opening () that is open to the gas-liquid contact chamber (). The liquid agent flow passage () branches into plural branch flow passages (for example, branches into a first branch flow passage () and plural second branch flow passages ()). Each of the plural branch flow passages has a liquid agent opening () that is open to the gas-liquid contact chamber (). The liquid agent openings () are respectively arranged at positions on the both sides sandwiching an extension region () of an adjacent flow passage () which is a part of the gas flow passage () adjacent to the gas opening ().

A liquid-agent dispensing container () includes: a mounting portion () that is mounted on a container body (); a swing portion () that is pivotally supported in a swingable manner with respect to the mounting portion () and has a force application portion () that receives a pressing force; an operating portion () that has a pressing portion that presses the force application portion () when pressed; an acting portion that transfers a pressing force from the swing portion () to a head portion () when the force application portion () is pressed; and a guide mechanism that guides a relative movement of the operating portion () with respect to the head portion () while maintaining a posture of the operating portion () when the operating portion () is pressed. At least a part of the head portion () is covered with the operating portion () when the liquid-agent dispensing container () is viewed in a direction in which the head portion () is pressed with respect to the mounting portion ().

A slit lamp microscope capable of appropriately and easily carrying out the setting of the optical system is provided. In storageof a slit lamp microscope, correspondence informationis stored in which standard setting conditions of an illumination systemand/or an observation systemare associated with each of multiple sites of an eye E. A searching partsearches the standard setting conditions corresponding to a site designated by an operation partfrom the correspondence information. A setting-state acquiring partacquires current setting states of the illumination systemand/or the observation system. A setting-state specifying part specifies, from among the current setting states acquired by the setting-state acquiring part, those differing from the standard setting conditions searched by the searching part. A controller displays information based on this specified result on the display
