Abstract: A sheet stacking device that can appropriately stack, at a fixed position, sheets that are discharged to a discharge tray, and a printing apparatus are provided. A presser member holds down, at a pressing position, the sheets stacked on the discharge tray. The presser member is moved from the pressing position to a retraction position in a period after discharging of a sheet has been started and before discharging of a succeeding sheet is started.

Abstract: A recording apparatus includes a head set lever which fixes a head cartridge to a carriage section. The head set lever is movable between a first position at which the head cartridge is fixed to the carriage section and a second position at which mounting and removal of the head cartridge on and from the carriage section is permitted. Attachment of an ink tank to the head cartridge is inhibited when the head cartridge is mounted on the carriage section and the head set lever is arranged at a position other than the first position.

Abstract: A device includes a conveying roller configured to convey a recording medium, a follower roller configured to press the recording medium against the conveying roller, a detector configured to detect a direction of skew of the conveyed recording medium, and a changer configured to change a state of contact between the recording medium and the conveying roller in accordance with a result of the detection by the detector such that a length of a portion of the conveying roller that is in contact with the recording medium in a conveyance direction is larger on a side toward which the recording medium is skewed than on an opposite side.

Abstract: An inkjet recording apparatus includes a first support member fixed to a chassis and configured to guide the motion of a carriage, and a second support member provided farther from a platen than the first support member. The gap between a recording head and the platen is changed by moving the second support member.

Abstract: A product having a glass layer is produced that can be produced at low cost and can exhibit excellent antibacterial function. A base body, a first glazing material capable of forming a first glass layer on a surface of the base body, and a second glazing material capable of forming a second glass layer containing a silver compound on the surface of the base body. A first glazing material layer comprising the first glazing material and, on the surface side, a second glazing material layer comprising the second glazing material are formed on the surface of the base body. The first glazing material layer and the second glazing material layer are melted to form a first glass layer and a second glass layer. The second glazing material layer has a higher viscosity upon melting than the first glazing material layer.

Abstract: A printing apparatus drive control method is provided which allows the user to select a drive mode in which a printing apparatus can be operated with reduced operation noise whatever print mode is set, such as a fine print mode or a fast print mode, thus eliminating a problem of emitting noisy operation sound to surroundings late at night when a level of noise is comparatively low. One or more of a plurality of motors, which cause a plurality of driven portions in the printing apparatus, such as paper supply unit, main scan unit and paper feed unit, to perform predetermined operations, can be driven in a normal drive mode or a silent drive mode selectively.

Abstract: A recording apparatus for recording on a recording sheet by recording means comprises a conveying roller for conveying a recording sheet on the upstream side of recording means in the recording sheet conveying direction, plural discharging rollers for conveying a recording sheet on the downstream side of recording means in the recording sheet conveying direction, and a common driving source for driving the plural discharging rollers. For this recording apparatus the driving force of the driving source is transmitted first to a discharging roller on the outermost downstream side in the recording sheet conveying direction. With the structure thus arranged, this recording apparatus is capable of forming images in good condition on the rear portion of a recording sheet by enhancing the conveyance precision only by use of discharging rollers without any significant cost increase for a recording apparatus provided with plural discharging rollers.

Abstract: A recording apparatus can mount a special recording material, such as a compact disc (CD) or the like, in a state of being accommodated in a tray and perform recording on the special recording material. In this recording apparatus, by an operation of mounting a tray guide into the main body of the recording apparatus, an arm of the tray guide is inserted between a spur base for holding a spur, and a platen for holding sheet discharge rollers. The spur base thereby raises to separate the spur from the sheet discharge roller, and a space to allow passage of the tray is formed.
