PURPOSE:To maintain a stop mode of oscillation of a horizontal oscillation circuit even if an X-ray protector is released and to improve the perfect operations of the horizontal oscillation circuit, by driving a horizontal output circuit with oscillation of the horizontal oscillation circuit and stopping the actuation of the horizontal output circuit with stop of oscillation through a control circuit. CONSTITUTION:The 1st power supply circuit S1 used with a horizontal oscillation circuit 1 consists of a diode D1 connected to the secondary winding of a transformer T1 and a capacitor C3. A horizontal output circuit (b) connected to a voltage reduction type chopper regulator circuit (a) consists of a primary winding of an oscillation transformer T2, a capacitor C5 and a transistor TRQ1. The 2nd power supply circuit S2 used with the circuit 1 consists of a diode D2 connect to the secondary winding of the transformer T2 and a capacitor C4. A control circuit (d) of the circuit (b) consists of a primary winding connected to the output terminal of the circuit 1 and a hot/cold separating transformer T4 coupled to the secondary winding connected to the base of a TRQ2 of a drive circuit (c). |
