An electronic whiteboard includes a power button, a display device, and circuitry that implements processes of detecting an operation of the power button being turned off, storing at least a part of visible information displayed on the display device from a time the power button was turned on until a time the power button was turned off in a first storage device upon detecting that the power button has been turned off, determining whether to display the visible information stored in the first storage device on the display device based on a first time corresponding to a power-on time recorded when the power button was turned on and a second time corresponding to the power-off time recorded immediately before the first time when the power button was turned off, and controlling the display device to display the stored visible information upon determining to display the stored visible information.

Electronic whiteboard, program, and information processing method

A distribution management apparatus includes a generator configured to generate still-picture data from content data, a converter configured to convert the still-picture data into video data, and a distributer configured to distribute the video data to each of a first communication terminal and a second communication terminal, which are capable of playing back and displaying the video data. When first operation data indicating an operation of zooming into a partial region of the video data being played back and displayed on the first communication terminal is transmitted, the converter generates video data representing a partial region, which depends on display/playback capabilities of the second communication terminal, of the video data being played back and displayed on the first communication terminal, and the distributer distributes the video data representing the partial region generated by the converter to the second communication terminal.

Distribution management apparatus, distribution method, and program

A coordinate detecting device, which is used in a system including a display section including a display surface, two optical sensor units disposed at one side of the display section and including light emitting and receiving surfaces, and optical reflection members disposed at other three sides of the display section, includes adjustment units adjusting the respective light emitting and receiving surfaces of the optical sensor units where the reflection light is irradiated and received, and impact absorption units absorbing impact applied to the respective optical sensor units.

Coordinate detecting device and electronic information board system

A coordinate detector includes a pair of light sensor units disposed on a side of a display part having a display surface to be touched by a target to be detected, optical reflective members respectively disposed on remaining three sides of the display part, and a sensor position adjusting unit configured to adjust a rolling direction of the light sensor unit with respect to the optical reflective members. When the target touches the display surface, coordinates of the target are detected based on light reflected off the optical reflective members that is received by the light sensor units.

A slide rail assembly includes an inner rail unit, a pair of first and second outer rails, first and second roller mounted to the inner rail unit, and third and fourth rollers mounted to the pair of first and second outer rails. The inner rail unit includes an inner substrate assembly, a pair of first bent portions provided to a first side of the inner substrate assembly, and a pair of second bent portions provided to a second side of the inner substrate assembly. The first outer rail includes a first outer substrate and a pair of third bent portions. The second outer rail includes a second outer substrate and a pair of fourth bent portions. The pair of first and second outer rails is disposed with the pairs of third and fourth bent portions facing inward, and slidable against the inner rail unit.

Slide rail assembly, sheet feeder, and image forming apparatus

An image forming apparatus includes a sheet feeding device (). The sheet feeding device () includes a sheet feeding cassette (), a push-up member (), a drive shaft (), and a rotation detecting device (). The rotation detecting device () includes an output gear connected to the drive shaft (). The output gear includes a gear main body provided with a gear tooth on its outer edge; and an electrode holding member that is attached to the gear main body. The electrode holding member is rotatably provided in the case () and a rotating electrode is attached to the electrode holding member. The electrode holding member is formed of at least one thermoplastic resin selected from the group consisting of POM, PA, PBT, PP, PE, ABS resin, PS, PPE, PC, and PMMA. The gear main body is formed of a material whose strength is higher than thermoplastic resin of which the electrode holding member is formed.

A developer container supplies developer to a development device and includes a storage, an opening, a first seal member, a through-hole, and a second seal member. The developer is supplied from the storage to the development device through the opening. The first seal member seals the opening and is pulled in a predetermined direction to unseal the opening. The through-hole guides the first seal member toward an opposite side of the opening. The second seal member is provided on at least one of a lead-in opening and a lead-out opening of the through-hole and elastically blocks the at least one of the lead-in opening and the lead-out opening. A non-bonded portion of the second seal member elastically blocks the at least one of the lead-in opening and the lead-out opening when the first seal member is pulled out from the through-hole through the non-bonded portion.

Developer container and image forming apparatus including the developer container with sealing mechanism providing enhanced usability

A process cartridge for use in an image forming apparatus includes a first unit, a second unit, and a coupling shaft. The first unit includes an image carrier, while the second unit includes a developer carrier. The coupling shaft is configured to couple the first unit and the second unit so as to be pivotable relative to each other. A distance between the image carrier and the developer carrier is adjustable by pivoting at least one of the first unit and the second unit without releasing the coupling of the first unit and the second unit via the coupling shaft.
