Provided is a floating-type on-water support apparatus comprising: a ball in which a guide groove is formed along a circumferential surface thereof; a floating unit including a floating part which floats on water and supports the ball so that the ball is rotatable; and a support rod of which one end is exposed above the water so that a structure is installable thereon and the other end is heavier than the one end so that the support rod stands vertically and which passes through the circumferential surface and is coupled to the ball, wherein the floating unit further includes a restriction protrusion fitted into the guide groove to restrict the ball from being rotated about an axis of the support rod.

Floating type aquatic support apparatus

Provided is a floating-type on-water support apparatus including: a ball; a floating unit including a floating part, wherein the floating part has an upper plate supporting the ball so that the ball is rotatable, an interior formed to be hollow, and a lower plate provided with a spherical surface portion and floats on water; a support rod coupled to the ball and having one end exposed above the water so that a structure is installable thereon and the other end heavier than the one end so as to stand vertically to be accommodated in the floating part; and a base unit having one end installed on a lower portion of the support rod to support the support rod and the other end in roll contact with the spherical surface portion.

Floating-type aquatic support apparatus

An image forming apparatus includes a sensor to output a signal, and a processor. The processor is to change an operation state of the image forming apparatus based on the signal indicative of an amount of change in the signal maintained for a time period.

Changing operational state of image forming apparatus based on distance of sensed body

An image forming apparatus includes a display configured to display a control menu to perform a function, a sensor configured to sense a user within a predetermined range and output a signal which has a voltage size corresponding to a distance of the sensed user, and a processor configured to change an operation state of the image forming apparatus based on a voltage change amount of the signal.

An image forming device comprises: an exposer having a plurality of light emitting devices, a light emitting device among the plurality of light emitting devices to transmit light toward a photosensitive drum; and a developer to develop an electrostatic latent image formed on a surface of the photosensitive drum by the light, wherein the light emitting device among the plurality of light emitting devices includes: a light emitting layer to generate the light; and a reflective layer to reflect at least a portion of the generated light. The reflective layer can include a plurality of sub-reflective layers, in which a thickness of a sub-reflective layer among the plurality of sub-reflective layers is different from a thickness of another sub-reflective layer among the plurality of sub-reflective layers, and/or a refractive index of a sub-reflective layer among the plurality of sub-reflective layers is different from a refractive index of another sub-reflective layer among the plurality of sub-reflective layers.
