    摘要: 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.

    摘要: 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.

    摘要: 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.
