A printer includes a transporting unit that performs a predetermined amount of continuous transporting with respect to a printing medium, a head that forms a designated number of unit images designated in advance from the beginning to the end of continuous transporting by ejecting ink onto the printing medium which is continuously transported by the transporting unit, a detection unit that detects a defect of the unit image formed by the head, and a control unit that controls the transporting unit, the head, and the detection unit. Here, the control unit increases the predetermined amount and the designated number based on a detection result of the defective image by the detection unit, and performs a process of re-forming the unit image corresponding to the number of defective images while the continuous transporting is performed.

A data processing device includes a cursor position decision unit, a display control unit, a switch operation signal detection unit, a storage unit, an event generation unit and an event execution unit. The storage unit is configured to store, for a predetermined period, at least one of cursor position information outputted from the cursor position decision unit and event information according to one of a plurality of selection options located in a displayed image at a position corresponding to the cursor position decided by the cursor position decision unit. The event generation unit is configured to generate an execution event when a first switch operation signal is detected at a first timing by the switch operation signal detection unit based on the at least one of the cursor position information and the event information stored in the storage unit at a second timing prior to the first timing.

Pointing device, data processing device, and data processing system

There is provided a printer that performs print on a medium by color materials, including: an advance information reading and writing section that reads and writes advance information from and in an advance information holder for storing the advance information; a print control section that outputs a print driving controlling print when the advance information is read by the advance information reading and writing section; and a used amount acquiring section that acquires a used amount for the printer based on the print driving signal output from print control section.

Printer, control method, and used amount acquiring method for outputting an amount of use of a printer

Since a power supply circuit for a controller () and a power supply circuit for a buffer storage unit () are independently provided, the power voltage for the buffer storage unit () need only be reduced to obtain a corresponding reduction in the amplitude of the signal waveform of digital image data transmitted along an FFC (), without the operation of the controller () being adversely affected. In addition, so long as a coil () is located at one position in the internal power supply circuit of a control chip (), or the external circuit thereof near its power supply circuit, the signal waveform for the digital image data transmitted along the FFC () can be attenuated.

Image reading apparatus

An image processing unit () includes a averaging circuit () and a memory () for storing pixel data. The memory () is a memory for storing the pixel data subjected to analog-to-digital conversion. The averaging circuit () performs an averaging process between two adjoining pixels on each line stored in the memory (). The digital pixel data is stored in the memory () and the averaging process is performed between the two pixels in the main scanning direction using the pixel data read by a first photoelectric conversion element trains and the pixel data read by a second photoelectric conversion element trains. Therefore, the noise component can be reduced, whereas the S/N ratio can be improved. Accordingly, image quality is made improvable with a simple arrangement.
