Abstract: A sheet package to be set in a sheet storage unit of a printer includes a stack of sheets and a package member covering the stack of sheets. The sheets are supplied from the sheet package to the printer along a sheet feed direction. The package member has a side part being in parallel with the sheet feed direction and having an edge at its front in the sheet feed direction. The side part is structured so that a projecting part of the sheet storage unit secures the position of the package member by contacting the front edge of the side part and the side edge of the stack of sheets when the package member is placed in the sheet storage unit relative to the sheet feed direction.

Abstract: A sheet package (9) to be set in a sheet storage unit (6, 106) of a printer (1) for supplying the printer with sheets comprises a stack of sheets (7) and a package member (8) covering the stack of sheets. When the sheet package (9) is set in the printer (1), the sheets (7) are supplied from the sheet package (9) to the printer (1) along a sheet feed direction. The package member (8) has a side part (53) spreading in parallel with the sheet feed direction and having an edge at its front in the sheet feed direction. On a side wall of the sheet storage unit (6, 106), a pressing member (41) for pressing a side face of the stack of sheets (7) is formed in order to align the stack of sheets (7) in a direction orthogonal to the sheet feed direction. The side part (53) places the package member at a proper position in the sheet storage unit (6, 106) in regard to the sheet feed direction by letting the edge make contact with the pressing member (41).

Abstract: A manual printing device for printing on a surface of a recording medium when manually scanned in a scanning direction over the recording medium, the manual printing device including: an elongated body to be manually grasped by a user and having an upper tip and a lower tip opposite the upper tip, the lower tip confronting the recording medium when the body is oriented with respect to the recording medium to print on the recording medium; an ink jet print head disposed at the lower tip and capable of printing at a maximum printing width on the surface of the printing medium; a frame disposed at the lower tip and, with respect to the scanning direction, in front of the ink jet print head; a roller rotatably supported on the frame to rotate across the surface of the recording medium when the manual printing device is scanned in the scanning direction over the recording medium; and a protrusion extending from the frame and, when the body is oriented to print on the recording medium, into contact with the recordi

Abstract: A compact printing device for printing inputted image data at a desired position on a print medium by scanning, in a scanning direction, the printer over the desired position of the print medium and including a body having a lower end confronting the print medium during printing, the lower end having a first region and a second region opposite each other with respect to a second direction perpendicular to the scanning direction; a print head for printing images on the print medium surface based on the inputted print image data and provided to the lower end of the body in the first region; and distance maintenance member for maintaining a set distance between the print head and the desired position on the print medium and provided to the lower end of the body in the second region.

Abstract: An apparatus for driving an electric motor, including a full-wave rectifier which rectifies an alternating current supplied from an alternating-current power supply, and supplies a full-wave rectified current to the motor, a chopper which chops the full-wave rectified current supplied from the rectifier to the motor so that the chopped current is applied to the motor, and a control device which generates a chopping pulse signal having a first signal characteristic corresponding to a given motor control target and a second signal characteristic to reduce an alternating-current component of the full-wave rectified current supplied to the motor, the control device supplying the chopping pulse signal to the chopper so that the chopper chops the full-wave rectified current according to the chopping pulse signal.

Abstract: A printing device includes a casing housing a sheet-feed mechanism for transporting a print medium and a carriage transporting mechanism for reciprocally moving a carriage in a main scanning direction. A print unit having a print head is detachably attached to the carriage. The print unit is capable of printing whether attached or detached from the carriage. A detection unit is provided for determining whether the print unit is attached to the carriage. The casing can be formed with a hollow space in which the print unit can be stored when the print device is not being used.

Abstract: An apparatus for driving an electric motor according to a given control target, including a control circuit which generates a control command signal corresponding to the control target, a chopping signal generator which generates a chopping signal based on the control command signal generated by the control circuit, a full-wave rectifier which rectifies an alternating current supplied from an alternating-current power supply, and supplies a full-wave rectified current to the motor, and a chopper which is connected in series to a series circuit including the motor and the full-wave rectifier and which chops the full-wave rectified current supplied to the motor according to the chopping signal generated by the chopping signal generator.

Abstract: A color image recording apparatus for recording a color image of an original document on a photosensitive paper using at least yellow, magenta and cyan liquid toners respectively containing yellow, magenta and cyan color materials as primary color components. At least one of the three liquid toners contains foreign color materials which are the primary color components of the rest of two liquid toners. To reproduce the color image of the original document with maximum possible fidelity, a disk-shaped rotary filter is provided for receiving imaging light separated into blue, green and red light components and changing light transmission rates passing through the filter so as to be equal to the proportion of the color material to be reproduced which is contained in the yellow, magenta and cyan liquid toners. The light transmission rates are changed each time when one of the yellow, magenta and cyan liquid toners is used.
