Description

本発明による電源装置は、第１の電圧を生成する第１生成手段及び第２の電圧を生成する第２生成手段を備える生成回路と、前記第１の電圧を有する第１の電力を出力する第１出力手段と、前記第１の電圧と前記第２の電圧を加算した電圧を有する第２の電力を出力する第２出力手段と、前記第１の電力の供給経路と前記第２の電力の供給経路の共通部分に設けられるヒューズと、を有する。 A power supply apparatus according to the present invention outputs a first circuit having a first voltage and a first generation unit that generates a first voltage and a second generation unit that generates a second voltage, and a first power having the first voltage. A first output means; a second output means for outputting a second power having a voltage obtained by adding the first voltage and the second voltage; a supply path for the first power; and the second power. having a fuse that is provided on the intersection of the supply path.

ヒューズＦＵ１は電流経路Ｘ上に設けられるので、第１の電力の負荷電流Ｉ１は、ダイオードＤ１から出力され、ヒューズＦＵ１を経由して出力端子Ｖ１から記録ヘッドに供給される。また、第２の電力の負荷電流Ｉ２は、ダイオードＤ１から出力され、ヒューズＦＵ１、２次巻線４及びダイオードＤ２を経由して出力端子Ｖ２から駆動源に供給される。 Since the fuse FU1 is provided on the current path X, the load current I1 of the first power is output from the diode D1 and supplied from the output terminal V1 to the recording head via the fuse FU1. The load current I2 of the second power is output from the diode D1, is supplied to the drive source via the fuse FU1,2 winding 4 and the diode D2 from the output terminal V 2.
