摘要:
In a medical X-ray CT apparatus, a rotary portion is rotated, and a wind is produced inside the apparatus by the rotation of the rotary portion. An expanded cover portion is forced to vibrate by the wind, and noise is produced. The expanded cover portion is provided with at least one curved member including both ends. The curved member is arranged to extend along a virtual projection line obtained by geometrically projecting a virtual straight line connecting, to each other, the two ends fixed to an outer peripheral edge of an opening of the expanded cover portion onto a surface of the expanded cover portion, and the vibration of the expanded cover portion is reduced.

A pressing unit includes a pressure roller that slides on the folded side while rotating, an elastic biasing unit that presses the pressure roller in a thickness direction of the stack of sheets, and a driving unit that slides the pressure roller in a direction substantially perpendicular to a conveying direction of the stack of sheets. A lifting unit, when the pressure roller slides to a first position, temporarily lifts up the pressure roller, and when lifted-up pressure roller slides to a second position, lifts the lifted-up pressure roller down onto the folded side.

A sheet alignment device, that is included in a sheet finishing apparatus integrally mounted with an image forming apparatus to an image forming system or connected to the image forming apparatus, includes an accommodating unit configured to temporarily accommodate a paper sheet and a paper sheet stack including the paper sheet therein, and a sheet alignment unit configured to align the sheet stack including the paper sheet in a direction perpendicular to a sheet travel direction. The sheet alignment unit has a first alignment member configured to move between a sheet receiving position and a sheet alignment position along the direction perpendicular to the sheet travel direction so as to push the sheet stack and a second alignment member configured to move to a fixed position and remain stationary thereat so as to stop the sheet stack pushed by the first alignment member.

A fixing apparatus and an image formation apparatus are disclosed. The fixing apparatus includes two or more heaters with temperature detecting function that generate heat with electric current and detect temperature; a heating unit that includes the heater with the temperature detecting function; a film, a surface of which slides on the heating unit; a thermal fixing unit that is heated by the heating unit through the film for fusing a toner image that is yet-to-be fixed on a recording paper at a predetermined fixing temperature; a pressurization roller for pressing the recording paper to the thermal fixing unit; and a temperature control unit for controlling the temperature of the heater to be a predetermined temperature based on the temperature of the heater detected by the heater with the temperature detecting function.

A sheet conveying device includes entrance rollers and registration rollers. The entrance rollers convey a sheet received from delivery rollers to the registration rollers. The registration rollers correct skew of the sheet. A conveying path between the delivery rollers and the registration rollers is equal to or slightly longer than a length of a sheet in a maximum allowable size for skew correction in a conveying direction in which the sheet is conveyed on the conveying path.

摘要:
A rotating unit forwards and rewinds a recording medium by rotating in a normal direction and in a reverse direction, respectively. A recording unit records an image on a surface of the recording medium. An erasing unit erases the image recorded on the surface of the recording medium. A shift-amount adjusting unit adjusts a shift amount per unit time of a forwarding portion of the recording medium at a recording position or on an upstream side of the recording position in a forwarding direction. A weight is fixed to the forwarding portion of the recording medium exposed outside from an opening that is provided on a casing.
摘要:
A data sheet is composed of an upper part and a lower part. The upper part is used as a user interface including a reduced image of contents of a document. The lower part is an interface for a reading device such as a copy machine, including a code obtained by encoding the document. By use of the data sheet, the user can easily distribute or carry an electronic document data with the user. In addition, the user can recognize contents of the electronic document data by looking at the reduced image printed on the data sheet.
