A processing apparatus comprises: an integrated circuit; a power supply unit connected to an external power supply and configured to perform power supply to the integrated circuit; and a power switch configured to switch a state of the processing apparatus based on power supplied from the power supply unit. The integrated circuit comprises a control unit configured to control a power state of the integrated circuit in a state in which power supply to the integrated circuit is being performed by the power supply unit.

Processing apparatus

The printing apparatus includes a light source that emits light to a first surface of a printing sheet; a sensor that detects the light reflected from the printing sheet; a reflection member located at a position facing the sensor and coming into contact with a second surface opposite to the first surface of the printing sheet; and a control unit configured to determine a type of the printing sheet based on a feature amount obtained by the sensor detecting the light from a plurality of positions of the printing sheet being conveyed, wherein a first area and a second area whose reflectance is lower than that of the first area are included in the reflection member and a position corresponding to the first area and a position corresponding to the second area are included in the plurality of positions.

Printing apparatus and control method of printing apparatus

A printing apparatus includes a conveyance unit configured to convey a sheet in a conveyance direction, a print unit configured to perform printing on the sheet conveyed by the conveyance unit, a light receiving unit configured to receive light and make an output according to the received light, and a control unit configured to control borderless printing by the print unit, the borderless printing including extra-printing from a sheet edge to outside of the sheet. The control unit sets an extra-printing amount by which printing extends off the sheet edge after the light receiving unit makes the output according to the received light.

Printing apparatus and method of controlling printing apparatus

A laser drive circuit is provided which includes: a first drive current unit () configured to adjust, by a first MOSFET (MN) and a second MOSFET (MN) being connected in series, an inflow of a current to a light-emitting element (LD) that emits light in accordance with a current amount when the light-emitting element emits light and when the light-emitting element is extinguished; a voltage drop unit (MN) configured to cause a gate-source voltage of the first MOSFET to drop when the light-emitting element is extinguished; and a timing generating unit () configured to generate a signal for controlling driving of the first drive current unit and the voltage drop unit.

Laser drive circuit and sensor apparatus

A printing apparatus includes a conveyance unit to convey a printing sheet in a conveyance direction, a printing unit to print on the conveyed printing sheet, a print unit, and a carriage to move in a direction crossing the conveyance direction. A detection unit detects a sheet edge of the print sheet based on output from a light receiving unit, and a control unit controls a borderless printing by the print unit that includes an extra-printing from the sheet edge to outside of the sheet. When the control unit performs the borderless printing, the control unit obtains an instruction to perform the borderless printing, and then causes the light receiving unit to obtain the output by causing the light emitting unit to emit the light, and thereafter the control unit sets an extra-printing amount by which printing extends off the sheet edge based on the obtained output.
