本考案はマグネツトを用いた表示装置に関する
もので、電源投入時の誤表示防止と電源の保護を
目的とする。[Detailed Description of the Invention] The present invention relates to a display device using a magnet, and its purpose is to prevent erroneous display when the power is turned on and to protect the power supply.
従来、操作部がロツクスイツチ式のマグネツト
反転表示装置においては、スイツチをONにした
まま電源を切つた場合、次に電源を入れた時にス
イツチがONになつている回路全部の表示部に電
流が流れる。しかし一般にマグネツト反転表示装
置は一度に数個の表示部しか動作させないため、
一度に多くの表示部に電流が流れると、過電流に
より電源の破壊またはヒユーズの切断という不都
合が生じる欠点があつた。また、そのため大容量
の電源を用意することは不経済である。 Conventionally, in magnetic reversing display devices with a lock switch type operation section, if the power is turned off with the switch on, current will flow through the display sections of all circuits whose switches are on the next time the power is turned on. . However, since magnetic reversing display devices generally operate only a few display parts at a time,
If current flows through many display sections at once, there is a disadvantage that the overcurrent may destroy the power supply or cut the fuse. Moreover, it is therefore uneconomical to prepare a large-capacity power source.
本考案はこの欠点を除去し、経済的に電源の保
護をはかるものである。以下にその一実施例とと
もに説明する。 The present invention eliminates this drawback and economically protects the power supply. This will be explained below along with one embodiment.

充電用高抵抗である。Ｐは電源回路である。 In the drawings, A is an operation unit, and B is a known magnetic reversal display device M1 to Mn that inverts the display each time a current with a different polarity is passed for a predetermined period of time.
C is a power source, X is a timing circuit that operates at a certain time when the power is turned on, and disconnects contact x.
S 1 to S o are operation switches, R 1 to R o are relays, C 1 to C o are capacitors, r 1 to r o are contacts of relays R 1 to R o , respectively, and R is a charging point when the power is turned on. High resistance for use. P is a power supply circuit.

する。 Next, the operation will be explained. Now, operate the operation switch S 1 ~ S
When the power is turned on with o on the M side, the timing circuit X in the power supply section C is turned on for a certain period of time.
state. At the same time, according to the operation of the timing circuit X, the contact x is kept open for a predetermined time t seconds.
At this time, a charging current flows in the loop of power supply circuit P → resistor R → operating switch S 1 -S o →C 1 -C o →R 1 -R o → power supply circuit P. However, by setting the resistance so large that the relays R 1 to R o do not operate, current will flow to the display sections M 1 to M o all at once even if the contacts R 1 to R o are left open. can be prevented. Next, after the above-mentioned predetermined time t seconds, the timing circuit X returns to its original state and the contact x also closes. At this time, since the capacitors C 1 -C o have already been charged, the relays R 1 -R o remain OFF, and the indicators M 1 -M o do not operate. In this state, if you turn the operation switches S 1 to S o to the B side,
The relays R 1 to R o operate due to the discharge of the capacitors C 1 to C o , the contacts r 1 to r o also operate according to the operation of the operation switch, and the indicators M 1 to M o of the display section M are also reversed. do.
次に操作スイツチS1〜Ｓoを再度Ｍ側に倒す
と、充電々流が電源回路Ｐの→接点ｘ→スイツ

→電源回路Ｐののループで流れ、リレーR1〜
ＲoがON状態となり、その接点r1〜ｒoもONとな
り表示部Ｍが反転し表示動作が可能となる。 Next, when the operating switches S 1 to S o are turned to the M side again, the charging current flows through the power supply circuit P → contact x → switches S 1 to S o → capacitors C 1 to C o → relays R 1 to R o
→Flows in the loop of power supply circuit P, relay R 1 ~
R o is turned on, and its contacts r 1 to r o are also turned on, so that the display section M is inverted and display operation becomes possible.
