PURPOSE:To efficiently detect the temp. of a coil with high accuracy, by connecting one of the lead wires of a temp. detection sensor to the conductive heat transfer member brought into contact with the coil of a printing magnet. CONSTITUTION:One of the lead wires 12a of a temp. sensor 12 is connected to a conductive heat transfer member 14 and a current is allowed to flow to the temp. sensor 12 through the heat transfer member 14. At the same time, the heat transferred to the conductive heat transfer member 14 from each of the coils 9 of a plurality of printing magnets is transferred to the temp. sensor 12 through the lead wire 12a. As a result, the temp. of each coil 9 can be efficiently detected with high accuracy by the reduced number of temp. sensors. |
