本発明は、電子回路を所謂イニシアル状態に戻すリセッ
トスイッチを備えた電子機器に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to an electronic device equipped with a reset switch for returning an electronic circuit to a so-called initial state.
（従来技術）
近年、電子技術の発達に伴いさまざまな機器に電子回路
が組み込まれ、電子化される傾向がある。(Prior Art) In recent years, with the development of electronic technology, there is a tendency for electronic circuits to be incorporated into various devices and electronic devices to be used.
これら電子化された機器は電子回路を作動させる為の電
源を持っているが、電源投入時電子回路の動作は不安定
となりやすい。その良い例としてはフリップフロップ回
路を数多く結線しであるレジスターやメモリー回路等が
ある。その為これら電子回路は、電源が投入されてから
ある一定時間が過ぎると、回路状態をイニシアル状態に
戻す為のリセット制御がなされる。しかし時として、電
源電圧が低かったり、電源投入時のチャタリング等が原
因で、リセット制御が行われないことがある。These electronic devices have a power source for operating the electronic circuits, but the operation of the electronic circuits tends to become unstable when the power is turned on. Good examples include registers and memory circuits that have many flip-flop circuits connected together. For this reason, these electronic circuits are subjected to reset control to return the circuit state to the initial state after a certain period of time has passed after the power is turned on. However, sometimes reset control may not be performed due to low power supply voltage or chattering when the power is turned on.
これだと機器本来の正常な動作が行われず、更に機器の
操作スイッチ等ではまったく制御がきかない、所謂機器
の暴走状態になる事がある。又、正常圧機器が作動して
いても、途中でノイズ等の外的要因が発生すると暴走状
態になってしまう事もある。そこでその対策としてイニ
シアル状態に戻す為のリセットスイッチが機器の操作部
に設けられている。If this happens, the device will not operate normally, and furthermore, the device may not be able to be controlled at all by the device's operation switches, resulting in a so-called runaway state of the device. Furthermore, even if a normal pressure device is operating, if an external factor such as noise occurs during the operation, it may become out of control. As a countermeasure against this, a reset switch is provided in the operation section of the device to return it to the initial state.
第１図はその一例であり、時計付電卓１にリセットスイ
ッチ３を設けた例を示す。２は液晶表示器を用いた表示
部で、４はキーボード部である。FIG. 1 is an example of this, and shows an example in which a calculator 1 with a clock is provided with a reset switch 3. 2 is a display section using a liquid crystal display, and 4 is a keyboard section.
第２図はリセットスイッチ５近傍の断面を示す。FIG. 2 shows a cross section near the reset switch 5.
ところで、このリセットスイッチ５は、不用意な操作を
禁止するために、そのキードッグ５ａは他のキートップ
６ａとは異なった形状をとらざるをえず、又キーゴム５
ｂの形状も他の６ｂとは異なったものにする必要がある
。更にこれらの制約によって１機器の厚みに薄さを要求
される電卓等では、リセットスイッチの抑圧（重すぎれ
ばリセットしにくくなり、軽ければ不用意に入りやすく
なる）の適正値設計が一段とむずかしくなる。By the way, in order to prevent careless operation of the reset switch 5, the key dog 5a has to have a different shape from the other key tops 6a, and the key rubber 5
The shape of b also needs to be different from the other 6b. Furthermore, due to these constraints, it becomes even more difficult to design an appropriate value for suppressing the reset switch (if it is too heavy, it will be difficult to reset, and if it is light, it will be easier to accidentally switch on it) in calculators and other devices that require a thin device. .
（目 的）
本発明の目的は、簡単な構成によって不用意な操作を禁
止し得るリセットスイッチを有する電子機器を提供する
ことを目的とする。(Objective) An object of the present invention is to provide an electronic device having a reset switch that can prohibit careless operation with a simple configuration.

卓の下ケース、１ｂは上ケース、８，９は電池である。(Embodiment) FIG. 6 shows an embodiment of the present invention, in which a reset switch 7 is provided in the battery compartment A of the small calculator 1 with a clock shown in FIG. The calculator is shown with the company's battery cover removed; 1a is the lower case of the calculator, 1b is the upper case, and 8 and 9 are the batteries.

なく大変好ましいものとなる。(Effects) As explained above, according to the present invention, it is possible to provide a reset switch with a very simple configuration and low cost.Moreover, since the switch is located in a place that cannot be touched from the outside of the device, There is no need to operate a switch. Therefore, there is no need to delete important data. Furthermore, in the case of a calculator with a clock like the one in this example, since it functions as a clock except during calculations, there is no need for a power switch, and it is common that no power switch is provided. The above-mentioned runaway condition occurs only during battery replacement, and from this point of view, providing a reset switch in the battery chamber makes it easier to operate the switches, such as battery replacement and reset. Also, from the exterior design point of view, it is not affected by tK as much as the reset switch, which is very preferable.
