    Abstract: An encoder is adapted to oppose to a scale provided with a plurality of marks or slits arranged in a first direction at predetermined intervals. A plurality of detectors is arranged in a second direction perpendicular to the first direction while being staggered in the first direction, each of which detects a position of each of the marks or slits, and the plurality of detectors being operable to respectively output an detection signal which have a first frequency. A first signal generator is operable to generate a first output signal which has a second frequency which is 2n-times of the first frequency based on the detection signal output from a first detector of the plurality of detectors. A second signal generator is operable to generate a second output signal which has the second frequency based on the detection signal output from a second detector of the plurality of detectors. A third signal generator is operable to generate a third output signal which has the second frequency based on the detection signal output from a third detector of the plurality of detectors. A fourth signal generator is operable to generate a fourth output signal which has the second frequency based on the detection signal output from a fourth detector of the plurality of detectors. A controller detects a rotational position of the motor and a rotational speed of the motor based on at least one of the first output signal, the second output signal, the third output signal, and the fourth output signal, and which controls the rotational speed of the motor by PID control based on the detected rotational position and the detected rotational speed. The controller stores a target speed table having a target rotational speed corresponding to the rotational position. The target speed table has the target rotational speed corresponding to the rotational position which is detected on the basis of at most three signals of one of the first output signal, the second output signal, the third output signal, and the fourth output signal.

    Abstract: A scanner provided with an image sensor that integrates reflected light that occurs due to reflections from a scan position, and then converts into specific image data the reflected light that has been integrated, and outputs this image data, wherein a plurality of segments, in the scan direction are provided for an object to be scanned by moving a scan position in the scan direction in the object to be scanned, where an image sensor is controlled so that, when the scan position passes over each of the segments of the object to be scanned, because of the motion of a carriage, the image sensor is controlled so as to start integrating the reflected light that occurs at the scan position with the timing with which the scan position enters into each of the segments of the object to be scanned, and thereafter, the image sensor is caused to stop integrating the reflected light after a specific amount of time has elapsed, where the reflected light that has been integrated is converted by the image sensor and outputted as image data for the segment, where the specific time interval is uniform for all segments. This prevents chromatic non-uniformities between the line image data.

    Abstract: An encoder is adapted to be opposed to a scale provided with a plurality of marks or slits arranged in a first direction such that a distance between centers of adjacent marks or slits in the first direction assumes a first length. Each of photo detectors has a light receiving region adapted to receive light emitted from a photo emitter and transmitted by way of the marks or slits, and is operable to output a detection signal in accordance with a quantity of the light received by the light receiving region. The photo detectors are arranged in a second direction perpendicular to the first direction while being shifted in the first direction by a second length which is one-sixteenth of the first length. Each of signal generators is operable to generate an output signal based on at least the detection signal outputted from one of the photo detectors. Each of exclusive-OR logic circuits is operable to perform a logical exclusive-OR calculation with respect to the output signals from two of the signal generators to generate an exclusive-OR signal. Some of the output signals and the exclusive-OR signals are output from the encoder. The level of the detection signal is changed in accordance with a relative movement between the marks or slits and the photo detectors, so as to have a first frequency. Each of the output signals has a second frequency which is double of the first frequency.

    Abstract: Reinforcing ridges are formed so as to project from corner portions of peripheral walls, and an opening end edge is made thick-walled, so that an ink cartridge having a sufficient rigidity can be molded using vapor impermeable soft synthetic resins. In addition, shape keeping ribs are formed so as to project from the outer sides of longitudinal ribs that are formed on an inner surface of a cover body, so that deformation of the cartridge can be suppressed during vibration welding. Further, an engaging recess arranged in a lower surface of an ink cartridge is adapted to receive a support rod of an ink cartridge loading mechanism. A carriage cover body of the loading mechanism is closed as a lifter is guided with a guide groove which is parallel to the axial center of an ink supply needle so that the ink cartridge is allowed to descend correctly toward a recording head, so that the ink cartridge can be loaded correctly without breaking the ink supply needle.
