Abstract

PURPOSE:To accelerate the exchange of a power source or the like, by providing a detection circuit to detect the change in driving power or driving signal. CONSTITUTION:A printing member 2 is selected by a data processing circuit 1. The printing member is operated by a driver circuit 3 in accordance with the selection. Motive power is applied from a motor circuit 5 to the printing member. At that time, a change such as the fall in driving power or driving signal is detected by a detection circuit 4. The operation of a transistor 7f is inhibited by a gate 8 or the like depending on the signal of the detection circuit so that no signal is transmitted to a heater 6f. As a result, some of printing elements of a printing head are put in a non-operating state. Since printing is made incomplete due to the non-operating state, the change in the driving power source or the like can be found out.
