Description
【発明の詳細な説明】
本発明は、テレビ受像機の電源投入時において、動作開

The purpose is to provide.
従来の回路では、先に始動しなければならない回路の電
圧が十分に立上ってから次の回路の電圧を印加するため
にトランジスタ等の数点の部品が必要であった。Conventional circuits require several components, such as transistors, to apply voltage to the next circuit after the voltage of the circuit that must be started first has risen sufficiently.
そこで本発明では、トランジスタ等の切換回路をなくす

イオード８を付加したものである。Therefore, the present invention provides a circuit that eliminates switching circuits such as transistors. Therefore, as shown in FIG. 1, a stabilizing circuit 4, In the circuit that supplies voltage from 6 to the circuits 6 and 7, a constant voltage diode 8 is added between the circuit 6, which has a high operation start voltage and must operate first, and the power supply terminal 1.

Let the operation start voltage of the circuit 6 be Va (point a), and the operation start voltage of the circuit element 4 (point b).

よりも早くなるため、正常動作が確実に行なわれる。Assuming that the circuit 6 has to start operating first, if the constant voltage diode 8 in FIG. 1 is not present, vl and ■
Since point 2 has the same rise, point 8 lags behind point b and cannot operate normally. Here, power supply voltage ■. and the voltage v1 supplied by the stabilizing circuit 4.
If added as shown in the figure, vl is d when diode 8 is turned on.
■ From point to point e where it turns off. It rises with a potential difference between and ■D. Therefore, the operation starting point a becomes 0 point, which is earlier than point b, so that normal operation is reliably performed.
第３図に別の回路例を示す。これは第２図のｖｌより電
圧が高く、立上りが十分早い電源端子９が別にある場合
第１図と同じ動作をするものである。FIG. 3 shows another circuit example. This operates in the same way as in FIG. 1 if there is another power supply terminal 9 whose voltage is higher than vl in FIG. 2 and which rises sufficiently quickly.
動作は第１図の場合と同様であるので省略する。The operation is the same as that shown in FIG. 1, so a description thereof will be omitted.
