Abstract: The disclosure provides a liquid administering device capable of accurately administering a liquid to a predetermined part in a nasal cavity. A liquid administering device 2 includes a main body 4, a first nozzle 6 that protrudes from the main body 4 in a predetermined direction and dispenses a liquid while being inserted into one nasal cavity 28a of a user, and a second nozzle 8 that protrudes from the main body 4 in the predetermined direction and is inserted into the other nasal cavity 28b of the user to position the first nozzle 6 with respect to one nasal cavity 28a.

Abstract: Provided is a nasal drop device which can simply and easily administer an appropriate amount of a solution to a specific site in the nasal cavity without waste. The nasal drop device 100 includes: an ejection portion 104 that ejects droplets into the nasal cavity; and a control portion that acquires suitability information indicating whether or not a current relative angle between a reference line indicating the posture of the face of a user who puts the nasal drop device 100 in the nose and a reference line indicating the posture of the nasal drop device 100 is suitable for the nasal drop, and controls the ejection operation of the ejection portion 104 according to the suitability information.

Abstract: An optical finder having a variable field of view that changes in synchronization with zooming of an imaging lens includes a tubular finder housing having opening portions on an objective side thereof and an opening portion on an eyepiece side thereof and a field of view limiting member for limiting an aperture corresponding to the field of view from the opening portion on the eyepiece side by protruding from an inner face of the finder housing. The field of view corresponding to the aperture is increased or decreased in synchronization with zooming of the imaging lens. The field of view limiting member includes four aperture limiting members that are pressed inward from upper, lower, left, and right inner faces of the finder housing and aperture adjusting members having oblique side portions that are sandwiched between a pair of the upper and the lower aperture limiting members and between a pair of the left and the right aperture limiting members respectively.

Abstract: A switchback device has an inverting tray for temporarily holding a sheet guided inside the switchback device thereon; a guide unit for guiding the sheet in pressing contact with the inverting tray when the sheet exits the switchback device in an exiting direction on the inverting tray, the exiting direction opposite to an entering direction of the sheet on the inverting tray; a guide switching unit for selectively changing the guide unit to a sheet guide allow state to allow the sheet to enter in the entering direction on the inverting tray and a sheet pressing state to make the sheet in pressing contact with the inverting; and a sheet transporting unit for transporting the sheet out of the switchback device in the exiting direction on the inverting tray.

Abstract: An image-forming machine comprising a rotary drum and a cleaning means which removes the toner remaining on the peripheral surface of the rotary drum. The cleaning means includes a support member that extends in the direction of center axis of the rotary drum, a blade-holding member that is mounted on the upper surface of the support member and extends in the direction of center axis of the rotary drum, and a cleaning blade that is held by the blade-holding means and extends in the direction of center axis of the rotary drum. The blade-holding member is allowed to swing on the swing axis that extends in a plane which is substantially perpendicular to the center axis of the rotary drum. An acute angle .alpha. is defined between the cleaning blade and a tangential line of the drum at a portion where the front end of the cleaning blade that is pushed comes into contact with the peripheral surface of the rotary drum, on the downstream side as viewed in a direction in which the rotary drum rotates.

Abstract: An image forming apparatus is provided with a photosensitive member; a charger including a corona ion generator and a grid electrode provided between the photosensitive member and the corona ion generator, and adapted for charging the surface of the photosensitive member while regulating the surface potential of the photosensitive member by the grid electrode; a current supply circuit connected to the charger and capable of supplying to the charger a first current not lower than a specified level for charging the surface of the photosensitive member at a first voltage at which an image of high contrast can be formed and a second current lower than the specified level for charging the surface of the photosensitive member at a second voltage at which an image having an intermediate gradation thereof emphasized is formed, the second voltage being lower than the first voltage; and a current switch circuit for switching the level of the current to be supplied to the charger means according to needs.

Abstract: An electrophotographic copying machine developer vessel includes a vessel proper having a closed top, a barrel and a tapered inclined portion continuous to the barrel. The developer vessel also includes a receiving plate removably attachable to the vessel proper, the receiving plate having a substantially flat supporting surface, substantially straight two side edges for attachment to the developing device and an opening communicating with the vessel proper. An opening tab composed of a film which covers the opening of the receiving plate is peelably bonded to the flat supporting surface thereof. A shutter is provided which includes a plate having, on both the sides thereof, engagement portions to be engaged with both the side edges of the receiving plate. The shutter may engage the receiving plate of the developer vessel such that when the developer vessel is removed from a copying machine, the presence of the shutter thereunder prevents scattering of developer in the environment.
