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.

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.

It is an object of the present invention to use a simple configuration to reduce the deviate of an image printed position caused by the behavior of a print sheet when the back end of the sheet slips out from an upstream roller pair. Thus, the present invention provides a printing apparatus including transporting section for transporting a print medium relative to printing heads for printing an image on a print sheet, the apparatus comprising vibrating section for vibrating the transporting section. This vibrating section vibrates the transporting section before the printing heads start a printing operation. Thus, even if the transporting section is stopped at an unstable position when a transporting operation is stopped, the applied vibration brings the transporting section into a stable state sufficiently before a printing operation is started.

An area on the printing sheet which can be printed through a single scanning operation of a printing head is divided into a plurality of smaller areas. The printing sheet is transported a distance corresponding to each divided area to print the image using different nozzles of the printing head for each divided area. When a back end portion of the printing sheet is printed, the distance transported is reduced to set inoperative nozzles that are not used for the printing operation. Then, when the printing sheet slips out from the upstream roller pair and it is then detected that the printing sheet is to be transported a distance longer than predetermined amount of rotation of the roller, the inoperative nozzles are used to shift an operative nozzle range depending on the extra amount of rotation. Thus, the extra transportation of the printing sheet is corrected.

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.

A printer has a pair of a right side member (8) and a left side member (9) placed on opposite side portions of a base (53), rollers including a transport roller (3), a carriage chassis (12), a platen (2) and a feed unit. The right side member and the left side member are formed by molding a resin material. The roller, the carriage chassis, the platen and the feed unit are positioned and held with the pair of the right side member and the left side member.
