    摘要： An imaging apparatus includes a printing mechanism having a media path. A print media source is provided for supplying a sheet of print media to the printing mechanism. A drive unit is provided, with a drive shaft coupled to the drive unit. A media sensor device is mounted to the drive shaft, wherein as the drive shaft is rotated in a first direction the media sensor device is moved from a first position that is out of the media path to a second position that is in the media path for sensing the sheet of print media. As the drive shaft is rotated in a second direction opposite to the first direction the media sensor device is moved from the second position that is in the media path for sensing the sheet of print media to the first position that is out of the media path.

    摘要： A printing apparatus comprises feeding means, light-emitting means, and a light-receiving sensor, and is capable of detecting a change in an output value of the light-receiving sensor that is caused by the medium to be printed, which has been fed by the feeding means, blocking the light, which has been emitted by the light-emitting means, wherein, by moving the light-emitting means and the light-receiving sensor in a main scanning direction, the printing apparatus detects, at a plurality of positions, changes in the output value that are caused by an upper or lower edge of the medium to be printed blocking the light, and based on a result of the detection, the printing apparatus obtains a position, in the feeding direction, of either one of a left edge or a right edge of the upper or lower edge that is fed leading or trailing the other in the feeding direction.

    摘要： A reciprocating linear encoder includes a linear encoder and a sensor. The linear encoder is configured to latch, follow and release print media in a periodic motion. The sensor is responsive to movement of the linear encoder, and is configured to output a signal associated with print media movement.

    摘要： In an optical distance measuring device of the invention, an objective lens condenses light from a light emission element to irradiate a measuring object and to form on the measuring object a light spot having a diameter not smaller than 10 nullm and not larger than 30 nullm. A light receiving lens condenses light reflected from the light spot on the measuring object to make the light incident on a photodetector through a pinhole having a diameter not smaller than 10 nullm and not larger than 50 nullm. With movement of the measuring object, detection signal of which an amplitude and an output level change according to a distance to the measuring object is obtained from the photodetector. Therefore, the distance and a change in the distance can be measured accurately, even if a surface of the measuring object is close to a mirror surface.
