A recording apparatus which is for filling recording ink in a film with numerous minute orifices and heating the ink rapidly with heating elements to spurt the ink from the orifices by means of the pressure of bubbles generated in heating to record data on a member to be recorded by use a source voltage from outside. The present recording apparatus comprises main switch for controlling the ON/OFF of the source voltage; sensor for detecting the ON/OFF state of said main switch; members for housing the film in a state of tight sealing; drive unit for variably controlling the motion of the film; sensor for detecting that the film is housed in said film housing member; a main power supply for supplying an operating power to at least said film motion drive unit by receiving the source voltage; and relay for shutting off the supply of the source voltage to said main power supply only when a detection signal is supplied from said film housing sensor. The film motion drive unit controls to transport a predetermined portion of the film into said film housing members according to the OFF state detection signal from the ON/OFF state sensor.
