Abstract: A control device comprises: a movement control unit configured to control movement of an object; a detecting unit configured to optically detect, at a specific position, the object moving through control by the movement control unit, to thereby output a detection voltage; and a movement amount determining unit configured to determine a movement amount of the object to be moved through the control by the movement control unit, based on a tendency of a change in the detection voltage when the object is moved.

Abstract: A thermal head control device includes: a printing rate calculation range determination unit configured to determine, as a printing rate calculation range, a range from a left-end energization dot to a right-end energization dot among energization dots present in printing data corresponding to heating elements to be controlled among a plurality of heating elements included in a thermal head; a printing rate calculation unit configured to calculate a printing rate of the printing rate calculation range determined by the printing rate calculation range determination unit; an energizing time calculation unit configured to calculate an energizing time for which a current is caused to flow through the heating elements based on the printing rate calculated by the printing rate calculation unit; and an output unit configured to output a control signal for driving the heating elements to be controlled of the thermal head, based on the calculated energizing time.

Abstract: A printer includes: a first connector to be used to input electric power supplied from an outside; a second connector to which a communication terminal is to be connected, and which is to be used to output at least a part of the electric power to the connected communication terminal; a printing control unit configured to control operation of a printing unit configured to perform printing on recording paper; and an adjustment unit configured to adjust a maximum amount of the electric power to be output from the second connector, of the electric power supplied from the outside, to a first amount of power when the printing unit is not under a printing operation, and adjust the maximum amount of the electric power to be output from the second connector to a second amount of power when the printing unit is under the printing operation, the second amount of power being smaller than the first amount of power.
