Abstract: A printing apparatus includes a communication interface, a memory, a touch panel, a printer, and a controller. The printer prints an image on a recording medium. The controller is configured to: receive a print job through the communication interface and store the print job in the memory; control the touch panel to display a list including one or more job touch keys and a function touch key, the one or more job touch keys being for individually selecting one or more print jobs stored in the memory, the function touch key being for selecting all of the one or more job touch keys included in the list, the list being scrollable along a particular direction; and in response to receiving a scroll operation of the list, controlling the touch panel to cause the list to scroll along the particular direction.

Abstract: According to one embodiment, a crank portion is formed from a crank piece, an element separate from a shaft portion. The crank piece includes a fitting hole in which the shaft portion is fit by predetermined “interference” and a slit-like slot with one end opened in an inner circumferential surface of the fitting hole, and an other end closed inside the crank piece. The fitting hole is deformed so as to expand its diameter when expanding a width of the slot. The shaft portion is fit in the fitting hole of the crank piece by the predetermined “interference” when inserted in the deformed fitting hole and the fitting hole restores an original form while the shaft portion is in the fitting hole.

Abstract: According to one embodiment, an operating state management device includes a first memory, a processor, and a second memory. The first memory is configured to store, in each of a plurality of operating state management target devices, feature patterns of detection states of a plurality of sensors that detect states of individual components in association with operating states. The processor is configured to compare patterns corresponding to actual detection states of the plurality of sensors with the feature patterns stored in the first memory, and determine operating states. The second memory is configured to store the determined operating states in time series.

Abstract: A stereoilithography apparatus includes a first optical system, a second optical system, an area setter and a moving mechanism. The first optical system emits a first light to a photocurable material. The second optical system emits a second light to the photocurable material such that a target area is formed in the photocurable material. The target area linearly intersects the first light in a first direction. The area setter sets a first area and a second area for at least one of the first light and the second light in the first direction at the target area. The first area and the second areas have different optical properties from each other. The moving mechanism moves the target area. The stereolithography apparatus cures the photocurable material at the target area.

Abstract: According to an embodiment, a bush includes a first member, a second member, and a third member. The first member is provided with a first hole having a first axis, and has a first outer surface having a second axis different from the first axis. The second member is provided with a second hole in which the first member is housed, and has a second inner surface that is in contact with the first outer surface and a second outer surface having a third axis different from the second axis. The third member is provided with a third hole in which the second member is housed and has a third inner surface that is in contact with the second outer surface.

Abstract: According to an embodiment, a high-rigidity plate includes: a first protrusion including a first top wall configured to support a vibration member and a first circumferential wall connected with an outer circumferential edge of the first top wall, the first protrusion being configured to protrude inside a housing or outside the housing; an intermediate part disposed at a position surrounding the first top wail when viewed along a first direction and connected with the first circumferential wall via a first bend; and an annular second protrusion including a second top wall disposed at a position surrounding the first top wall when viewed along the first direction and a second circumferential wall connected with the intermediate part via a second bend and connected with an inner circumferential edge of the second top wall, the second protrusion being configured to protrude inside the housing or outside the housing.

Abstract: According to one embodiment, a USB device includes a USB connector, a casing, and a holding member. The casing is provided with an opening. The holding member includes a holder, a support, and a first extension. The holder holds the USB connector. The support extends from the holder. The first extension has a protrusion, extends from the support, and is bendable. The protrusion is housed in the opening.

Abstract: According to an embodiment, a shower plate includes a first member and a second member. The first member includes a first wall provided with a plurality of first openings and internally including a room with which the first openings communicate. The second member includes a second wall provided with a second opening and arranged in the room. The second member is arranged at a position spaced apart from the first member, and allows one of the first openings facing the second opening to be replaced with another of the first openings by changing a position of the second member with respect to the first member.

Abstract: A slide structure comprises first and second members, a slider, a guide, and a first elastic part. The second member is movably supported by the first member. The slider is provided in one of the first member and the second member. The guide is provided in the other of the first member and the second member. The guide movably supports the slider among a first holding position, a slide section, and a second holding position. The first holding position is away or offset from a first position in a first direction. The slide section extends between the first position and a second position. The second position is distant from the first position in a second direction intersecting with the first direction. The second holding position is away or offset from the second position in the first direction.

Abstract: In a stereolithography apparatus according to an embodiment, for example, a first optical system emits a first light to a photocurable material. A second optical system emits a second light to the photocurable material such that the second light linearly intersects the first light in a first direction in the photocurable material. An area setter sets, for at least one of the first light and the second light, a first area and a second area having different optical properties from each other, at an intersection of the first light and the second light in the first direction. A moving mechanism moves the intersection of the first light and the second light. The stereolithography apparatus cures the photocurable material at the intersection of the first light and the second light.
