The sheet has regions facing the keys on the keyboard, and an optional key indication based on a language environment different from the given language environment is provided in the regions so as to be visible by an operator when the sheet covers the keyboard. If the operator's use language is different from a language of the standard key indication on the keyboard, the keyboard is covered by the sheet supporting the operator's use language. In this way, an electronic apparatus coupled to the keyboard is set to support the language environment of the operator.

Abstract: A full-color electrophotographic apparatus of the present invention is configured such that a toner image is formed on an intermediate transfer member. The intermediate transfer member is heated to a temperature equal to or higher than the softening start temperature of resin contained in a liquid toner and equal to or lower than the withstand temperature of a photoconductor member. A carrier-removing roller to which bias can be applied abuts the intermediate transfer member so as to remove a carrier while packing softened toner by the force of an electric field induced by bias. In a transfer section for transfer to a printing medium, a backup roller presses the printing medium against the intermediate transfer member, and the toner image is transferred from the intermediate transfer member to the printing medium. Before being pressed against the toner image on the intermediate transfer member, the printing medium is heated.

Abstract: The present invention provides a toner recycling control system which stably feeds a liquid developer of an appropriate concentration to a liquid developing apparatus employing a high-viscosity liquid developer; appropriately adjusts the concentration of residual developer collected after development and after transfer; and feeds the adjusted developer to the developing apparatus. The toner recycling control system collects a post-development residual developer from a developer-bearing body and a post-transfer residual developer from an image-bearing body; performs developer concentration adjustment to yield an adjusted developer; and feeds the adjusted developer back to the developer-bearing body.

Abstract: A switch mechanism 70 discriminates as to whether a lever 40 is in a detent position or not. When the lever is in the detent position, a detent device 80 is activated by a fluid pressure to produce a force for holding the lever in the detent position. The operation of the detent device is dismissed when the lever is not in the detent position. A pressure sensor 97 detects whether the operator's hand is in touch with the grip 49 of the lever, thus determining whether the operation of the detent device 80 is necessary. An actuator 30 is operated or stopped in response to manipulation of the lever. When the lever is moved to a position other than the detent position, an operation reaction force of a level corresponding to the load pressure in the actuator is applied by reaction force device 60, 60' to the lever so as to enable the operator to sense any change in the load pressure and starting operation of the actuator.

Abstract: An operating force controlling device includes a pair of reactive force mechanisms (70, 70') disposed in an opposing relationship to each other in the direction of operation of an operating lever (60). A load pressure of a motor (30) is detected by a detector (91, 91'), and a controlling signal is outputted from a controller (90) in response to the load pressure. A pilot pressure is outputted from an electromagnetic proportional pressure reducing valve (80) in response to the control signal. The pilot pressure is inputted into one of the chambers of the reactive force mechanisms (70, 70') which moves a rod (72, 72') to project, to apply an operation reactive force to the lever (60). The operation reactive force is controlled such that the rate of change thereof may be high when the load pressure of the motor (30) is low but may be low when the load pressure is high.
