Abstract: There are provided an original table for an original, a linear image sensor for converting light into an electric signal, a first optical system for forming an optical image on a main scanning line onto the linear image sensor, a sub scanning unit for scanning the main scanning line in parallel with a sub scanning direction, and a second optical system forming an optical path that reaches the linear image sensor from a detecting position on the plate surface, which is remote from the main scanning line in a sub scanning direction. A size and an orientation of an original are decided based on an electric signal converted from light that reaches the linear image sensor from the main scanning line via the first optical system, and an electric signal converted from light that reaches the linear image sensor from the detecting position via the second optical system.

Abstract: There are provided an original table (11) for an original, a linear image sensor (20) for converting light into an electric signal, a first optical system (30) for forming an optical image on a main scanning line onto the linear image sensor, a sub scanning unit for scanning the main scanning line in parallel with a sub scanning direction, and a second optical system (40) forming an optical path that reaches the linear image sensor from a detecting position (P) on the plate surface (12), which is remote from the main scanning line in a sub scanning direction. A size and an orientation of an original are decided based on an electric signal converted from light that reaches the linear image sensor from the main scanning line via the first optical system, and an electric signal converted from light that reaches the linear image sensor from the detecting position via the second optical system.

Abstract: An automobile wiper that restricts relative pivoting between the arm and the wiper blade without increasing costs. The automobile wiper includes a wiper blade having an upper wall on which an opening is provided. A clip is supported by a pin in the opening pivotally relative to the wiper blade. The clip has a flange extending perpendicular to the pin. The distal end of the arm is fixed to the clip. Relative pivoting between the clip and the wiper blade is restricted by contact between the flange and the lower surface of the upper wall of the wiper blade.

Abstract: A serial printer wherein a print head is reversibly displaced transverse to a print medium by an open looped grooved rotating cylindrical cam is provided. A unidirectional drive shaft is operatively coupled to the cam by a drive gear engaged with planet gears mounted on a clutched rotary member for rotating the cam when the rotary member is stationary. An intermediate gear is intermittently engaged with the drive gear for changing the rotating direction of the cam upon engagement of the intermediate gear between the drive gear and planet gear. The rotary member includes geared regions adapted to be engageable with a print medium advancing assembly for advancing the recording medium during rotation of the rotary member when the drive of the print head is stopped and the direction of the cylindrical cam is about to be reversed.
