Description

本発明は、操作端末器に関するものである。 The present invention relates to an operation terminal.

従来から、図７に示すように、それぞれ固有のアドレスが設定される１乃至複数の制御スイッチ１０３ａ，１０４ａ，１０５ａを有する複数台（図では３台）操作端末器１０３〜１０５と、１乃至複数の負荷（図示せず）が接続され、２線式の信号線Ｌｓを介して操作端末器１０３〜１０５に接続されるとともに、制御スイッチ１０３ａ，１０４ａ，１０５ａが操作されたときに信号線Ｌｓを介して操作端末器１０３〜１０５から受け取る監視データに基いて、操作された制御スイッチ１０３ａ，１０４ａ，１０５ａに対応した負荷を制御する制御装置としての制御親器１０１及び制御子器１０２とを備える遠隔制御システムが提供されている（例えば、特許文献１参照）。信号線Ｌｓに対する接続形態は、マルチドロップ接続となっている。 Conventionally, as shown in FIG. 7, a plurality (three in the figure) of operation terminals 103 to 105 each having one to a plurality of control switches 103a, 104a, and 105a, each having a unique address, and one to a plurality of control terminals. Load (not shown) is connected to the operation terminals 103 to 105 via the two-wire signal line Ls, and when the control switches 103a, 104a, 105a are operated, the signal line Ls is connected. Remote control device 101 and control device 102 as a control device for controlling the load corresponding to the operated control switch 103a, 104a, 105a based on the monitoring data received from the operation terminals 103-105 via A control system is provided (see, for example, Patent Document 1). The connection form for the signal line Ls is a multi-drop connection.

具体的に説明すると、制御親器１０１及び制御子器１０２はそれぞれ負荷への給電路に挿入されたリレー（図示せず）を有し、リレーを制御することで負荷への給電をオンオフすることにより負荷をオンオフ制御する。制御親器１０１は８回路（負荷８個分）のリレーを有し、制御子器１０２は４回路（負荷４個分）のリレーを有する。 More specifically, each of the control parent device 101 and the control child device 102 has a relay (not shown) inserted in a power supply path to the load, and turns on / off the power supply to the load by controlling the relay. The load is turned on and off by The control master unit 101 has eight circuit (eight load) relays, and the control unit 102 has four circuit (four load) relays.

また、操作端末器１０３〜１０５が有する制御スイッチ１０３ａ，１０４ａ，１０５ａには、例えば特許文献２にも示されているような周知の押釦スイッチが用いられる。 As the control switches 103a, 104a, and 105a included in the operation terminals 103 to 105, for example, a well-known push button switch as shown in Patent Document 2 is used.

以下、上記の遠隔制御システムの動作を説明する。 The operation of the above remote control system will be described below.

制御親器１０１は、信号線Ｌｓに対し、図８（ａ）に示すフォーマットの伝送信号Ｖｓを送出する。伝送信号Ｖｓは、信号送出開始を示すスタートパルス信号ＳＴ、伝送信号Ｖｓのモードを示すモードデータＭＤ、制御子器１０２や操作端末器１０３〜１０５を格別に呼び出すためのアドレスデータＡＤ、制御の指示が示される制御データＣＤ、伝送誤りを検出するためのチェックサムデータＣＳ、制御子器１０２や操作端末器１０３〜１０５から返送された監視データを受信するタイムスロットである信号返送期間ＷＴよりなる双極性（±２４Ｖ）の時分割多重信号であり、図８（ｂ）に示すようなパルス幅変調によってデータが伝送されるようになっている。 The control master 101 sends a transmission signal Vs having the format shown in FIG. 8A to the signal line Ls. The transmission signal Vs includes a start pulse signal ST indicating the start of signal transmission, mode data MD indicating the mode of the transmission signal Vs, address data AD for calling the control unit 102 and the operation terminals 103 to 105, and a control instruction. Is a bipolar signal including a control data CD, a checksum data CS for detecting a transmission error, and a signal return period WT which is a time slot for receiving monitoring data returned from the control unit 102 or the operation terminals 103 to 105. (± 24V) time division multiplexed signal, and data is transmitted by pulse width modulation as shown in FIG. 8 (b).

制御子器１０２及び操作端末器１０３〜１０５では、信号線Ｌｓを介して受信した伝送信号Ｖｓ中のアドレスデータＡＤが、自身が有するリレーや制御スイッチ１０３ａ，１０４ａ，１０５ａに予め設定されているアドレスのいずれかに一致すると、伝送信号Ｖｓから制御データＣＤを取り込むとともに、伝送信号Ｖｓの信号返送期間ＷＴに監視データを電流モード信号として返送する。なお、電流モード信号とは、信号線Ｌｓを適当な低インピーダンスを介して短絡することにより送出される信号である。 In the control unit 102 and the operation terminals 103 to 105, the address data AD in the transmission signal Vs received via the signal line Ls is an address set in advance in the relay and the control switches 103a, 104a, and 105a that the control unit 102 and the operation terminals 103 to 105 have. When the control data CD is equal to any one of the above, the control data CD is taken from the transmission signal Vs, and the monitoring data is returned as a current mode signal during the signal return period WT of the transmission signal Vs. The current mode signal is a signal transmitted by short-circuiting the signal line Ls through an appropriate low impedance.

制御親器１０１は、通常時には、モードデータＭＤをダミーモードとした伝送信号Ｖｓを一定時間間隔で送出する、いわゆる常時ポーリングを行なっている。操作端末器１０３〜１０５は、制御スイッチ１０３ａ，１０４ａ，１０５ａが操作されたときには、ダミーモードの伝送信号Ｖｓのスタートパルス信号ＳＴに同期させて図８（ｃ）に示すような割込信号Ｖｉを発生させる。このとき、割込信号Ｖｉを発生させた操作端末器１０３〜１０５は割込みフラグを設定して制御親器１０１との以後の情報授受に備える。制御親器１０１は、割込信号Ｖｉを受信すると、モードデータＭＤを割込ポーリングモードとし且つアドレスデータＡＤの上位の半数のビットを順次増加させながら伝送信号を送出し、割込信号Ｖｉを発生させた操作端末器１０３〜１０５では、操作された制御スイッチ１０３ａ，１０４ａ，１０５ａに予め設定されているアドレス（以下、「制御アドレス」と呼ぶ。）の上位の半数のビットに、割込ポーリングモードの伝送信号ＶｓのアドレスデータＡＤの上位の半数のビットが一致するとき、信号返送期間ＷＴに制御アドレスの下位の半数のビットを制御親器１０１に返送する。 The control master unit 101 performs so-called polling at all times, in which the transmission signal Vs in which the mode data MD is set to the dummy mode is sent at regular time intervals. When the control switches 103a, 104a, and 105a are operated, the operation terminals 103 to 105 generate an interrupt signal Vi as shown in FIG. 8C in synchronization with the start pulse signal ST of the dummy mode transmission signal Vs. generate. At this time, the operation terminals 103 to 105 that have generated the interrupt signal Vi set an interrupt flag to prepare for subsequent information exchange with the control parent device 101. When receiving the interrupt signal Vi, the control parent device 101 sets the mode data MD to the interrupt polling mode and sends the transmission signal while sequentially increasing the upper half of the address data AD to generate the interrupt signal Vi. In the operated operation terminals 103 to 105, the interrupt polling mode is used for the upper half of the addresses (hereinafter referred to as “control addresses”) preset in the operated control switches 103a, 104a, and 105a. When the upper half bits of the address data AD of the transmission signal Vs match, the lower half bits of the control address are returned to the control master unit 101 during the signal return period WT.

制御親器１０１は、上記の信号返送期間ＷＴに制御アドレスの下位の半数のビットを獲得し、上記アドレスデータＡＤの上位の半数のビットと合わせて、制御アドレスの全体を獲得すると、モードデータＭＤを監視モードとし、獲得された制御アドレスをアドレスデータＡＤとする伝送信号Ｖｓを信号線Ｌｓに送出する。この伝送信号Ｖｓの信号返送期間ＷＴに、割込信号Ｖｉを発生させた操作端末器１０３〜１０５は、操作された制御スイッチ１０３ａ，１０４ａ，１０５ａの操作状態を返送する。 When the control master unit 101 acquires the lower half of the control address in the signal return period WT, and acquires the entire control address together with the upper half of the address data AD, the mode data MD Is set to the monitoring mode, and a transmission signal Vs having the acquired control address as the address data AD is sent to the signal line Ls. During the signal return period WT of the transmission signal Vs, the operation terminals 103 to 105 that have generated the interrupt signal Vi return the operation states of the operated control switches 103a, 104a, and 105a.

最後に、制御親器１０１は、割込信号Ｖｉを発生させた操作端末器１０３〜１０５に対し、割込フラグの解除を指示する信号を送出し、割込信号Ｖｉを発生させた操作端末器１０３〜１０５はこの信号を受けて割込フラグを解除する。 Finally, the control parent device 101 sends a signal instructing the cancellation of the interrupt flag to the operation terminals 103 to 105 that have generated the interrupt signal Vi, and the operation terminal device that has generated the interrupt signal Vi. 103-105 receives this signal and cancels the interrupt flag.

以上のようにして、操作端末器１０３〜１０５から制御親器１０１への情報伝送は、制御親器１０１から操作端末器１０３〜１０５への４回の信号送出（ダミーモード、割込ポーリングモード、監視モード、割込リセット）によって完了する。 As described above, information transmission from the operation terminals 103 to 105 to the control terminal 101 is performed by sending four signals from the control terminal 101 to the operation terminals 103 to 105 (dummy mode, interrupt polling mode, Completed by monitoring mode, interrupt reset).

また、制御親器１０１が制御子器１０２からリレーの動作状態の情報を得ようとするときには、モードデータＭＤを監視モードとした伝送信号Ｖｓが用いられる。 Further, when the control master 101 tries to obtain information on the operation state of the relay from the control slave 102, the transmission signal Vs in which the mode data MD is set to the monitoring mode is used.

ここで、制御親器１０１は、制御スイッチ１０３ａ，１０４ａ，１０５ａのアドレスと各リレーとの対応関係を管理しており、操作された制御スイッチ１０３ａ，１０４ａ，１０５ａのアドレス（制御アドレス）と該制御スイッチ１０３ａ，１０４ａ，１０５ａの操作状態とを獲得すると、制御アドレスに対応付けられたリレーを制御親器１０１自身が有しておればそのリレーを上記操作状態に応じた状態とするようにオンオフ制御する。さらに、制御アドレスに対応付けられたリレーを制御子器１０２が有しておれば、モードデータＭＤを制御モードとし、アドレスデータＡＤを上記リレーのアドレスとし、行なわれるべき制御の内容の指示が制御データＣＤに含まれる伝送信号Ｖｓを信号線Ｌｓに送出する。制御子器１０２は、自身が有するリレーのアドレスがアドレスデータＡＤに示された伝送信号Ｖｓが受信されると、該リレーを制御データＣＤに示された指示のように制御するとともに、制御後のリレーの状態を示す監視データを信号返送期間ＷＴに返送する。制御親器１０１では、送出した制御データＣＤと返送された監視データとの関係により、伝送信号Ｖｓが正常に受信されたことを確認する。 Here, the control master unit 101 manages the correspondence between the addresses of the control switches 103a, 104a, and 105a and the respective relays. The addresses (control addresses) of the operated control switches 103a, 104a, and 105a and the control switches are controlled. When the operation states of the switches 103a, 104a, and 105a are acquired, if the control parent device 101 itself has a relay associated with the control address, the on / off control is performed so that the relay is in a state corresponding to the operation state. To do. Further, if the control unit 102 has a relay associated with the control address, the mode data MD is set to the control mode, the address data AD is set to the address of the relay, and an instruction of the content of control to be performed is controlled. The transmission signal Vs included in the data CD is sent to the signal line Ls. When the control unit 102 receives the transmission signal Vs in which the address of the relay of the control unit 102 is indicated in the address data AD, the control unit 102 controls the relay as instructed in the control data CD. Monitoring data indicating the relay status is returned during the signal return period WT. The control master 101 confirms that the transmission signal Vs has been normally received based on the relationship between the transmitted control data CD and the returned monitoring data.

さらに、操作端末器１０３〜１０５が例えば点灯・消灯の別や光色によって負荷の動作状態（すなわちリレーのオンオフ）を表示する発光ダイオードのような表示手段を有する場合、制御親器１０１は、制御スイッチ１０３ａ，１０４ａ，１０５ａへの操作に応じた動作が完了した後は、モードデータＭＤを制御モードとし、制御されたリレーに対応する制御スイッチ１０３ａ，１０４ａ，１０５ａのアドレスをアドレスデータＡＤとし、制御データＣＤにおいて表示手段の制御を指示する伝送信号Ｖｓを信号線Ｌｓに送出する。これを受けて、操作端末器１０３〜１０５では、表示手段を制御して負荷の動作状態（厳密にはリレーの状態）を正しく表示させるとともに、制御後の表示手段の状態を示す監視データを信号返送期間ＷＴに返送する。制御親器１０１では、送出した制御データＣＤと返送された監視データとの関係により、伝送信号Ｖｓが正常に受信されたことを確認する。 Further, when the operation terminals 103 to 105 have a display means such as a light emitting diode that displays the operation state of the load (that is, the relay on / off state) by, for example, lighting / extinguishing or light color, After the operation according to the operation to the switches 103a, 104a, and 105a is completed, the mode data MD is set to the control mode, the addresses of the control switches 103a, 104a, and 105a corresponding to the controlled relays are set to the address data AD, and the control is performed. A transmission signal Vs for instructing control of the display means in the data CD is sent to the signal line Ls. In response to this, the operation terminals 103 to 105 control the display means to correctly display the operation state of the load (strictly speaking, the relay state), and send monitoring data indicating the state of the display means after the control. Return in the return period WT. The control master 101 confirms that the transmission signal Vs has been normally received based on the relationship between the transmitted control data CD and the returned monitoring data.

ここで、制御スイッチ１０３ａ，１０４ａ，１０５ａの操作に応じた制御の形態としては、１個の制御スイッチ１０３ａ，１０４ａ，１０５ａが１個のリレーに対応付けられる個別制御だけでなく、１個の制御スイッチ１０３ａ，１０４ａ，１０５ａが操作される度に複数個のリレーのオンオフが一括して切り換えられるグループ制御や、１個の制御スイッチ１０３ａ，１０４ａ，１０５ａが操作されたときに複数個のリレーがそれぞれ予め設定されたオンオフ状態に切り換えられるパターン制御もある。 Here, as a form of control according to the operation of the control switches 103a, 104a, and 105a, not only the individual control in which one control switch 103a, 104a, and 105a is associated with one relay but also one control. Group control in which a plurality of relays are collectively turned on and off each time the switches 103a, 104a, 105a are operated, and a plurality of relays are respectively operated when one control switch 103a, 104a, 105a is operated. There is also pattern control that can be switched to a preset on / off state.

そして、信号線Ｌｓには、各制御スイッチ１０３ａ，１０４ａ，１０５ａにそれぞれアドレスを設定するためのアドレス設定器１０６もマルチドロップ接続されている。

また、操作端末器に、アドレス設定器１０６の機能を持たせることも提案されている。すなわち、操作端末器において、押釦スイッチからなる切換スイッチを設け、通常の操作端末器１０３〜１０５と同様の動作を行う制御モードと、制御スイッチが押操作される度に押操作された制御スイッチのアドレスを変更する設定モードとの間で、動作モードが択一的に切り換えられるようにする。 It has also been proposed that the operation terminal device has the function of the address setting device 106. That is, the operation terminal is provided with a changeover switch including a push button switch, and a control mode in which the operation similar to that of the normal operation terminals 103 to 105 is performed, and the control switch that is pushed each time the control switch is pushed is operated. The operation mode is selectively switched between the setting mode for changing the address.

このような操作端末器では、制御スイッチを押操作しようとしたところを誤操作により切換スイッチが押操作されると、動作モードが切り換わってしまう。特に、所定の規格に準拠した寸法形状に形成された操作端末器において、設けられている制御スイッチや表示装置が多いことで寸法上の制約から制御スイッチと切換スイッチとの距離が近くなっているような場合、上記のような誤操作が発生しやすい。 In such an operation terminal, the operation mode is switched when the changeover switch is pushed by mistake in the operation to push the control switch. In particular, in an operation terminal formed in a dimensional shape conforming to a predetermined standard, the distance between the control switch and the changeover switch is reduced due to dimensional restrictions due to the large number of control switches and display devices provided. In such a case, the above-described erroneous operation is likely to occur.

本発明は、上記事由に鑑みて為されたものであり、その目的は、制御スイッチを押操作する際の切換スイッチの誤操作が抑制される操作端末器を提供することにある。 The present invention has been made in view of the above-described reasons, and an object thereof is to provide an operation terminal device in which erroneous operation of a changeover switch when a control switch is pushed is suppressed.

請求項１及び請求項３の発明によれば、ハウジングの前面には、いずれの制御スイッチの押釦の前端よりも後方に位置し前方から見て各制御スイッチと切換スイッチとをそれぞれ囲む平面形状の露出部が設けられていて、切換スイッチの押釦の前端は露出部よりも後方に位置するので、切換スイッチの押釦の前端が、制御スイッチの押釦の前端よりも後方に位置することになるから、切換スイッチの押釦の前端と制御スイッチの押釦の前端とが互いに同じ前後位置に配置されている場合に比べ、制御スイッチを押操作する際の切換スイッチの誤操作が抑制される。 According to the first and third aspects of the present invention, the front surface of the housing has a planar shape that is positioned behind the front end of the push button of any control switch and surrounds each control switch and changeover switch as viewed from the front. Since the exposed portion is provided and the front end of the push button of the changeover switch is located behind the exposed portion, the front end of the pushbutton of the changeover switch is located behind the front end of the pushbutton of the control switch. Compared to the case where the front end of the push button of the changeover switch and the front end of the pushbutton of the control switch are arranged at the same front and rear position, erroneous operation of the changeover switch when the control switch is pushed is suppressed.

また、請求項１及び請求項３の発明によれば、切換スイッチの押釦は、ハウジングの露出部に開口し球面形状に窪んだ切換凹部の底部に設けられた切換穴から切換凹部の内側に突出しているので、切換スイッチの押釦を切換凹部の内側に突出させない場合に比べ、手の指による切換スイッチの押操作が容易となり、切換スイッチの押操作にドライバー等の治具を用いる必要がない。また、請求項１及び請求項３の発明によれば、切換スイッチは、いずれの制御スイッチと比べても、押操作が受け付けられるために必要な押力が強く、且つ、前方から見た押釦の面積が小さいので、切換スイッチと各制御スイッチとで必要な押力および前方から見た押釦の面積それぞれを全て共通とする場合に比べ、切換スイッチの誤操作がより抑制される。 According to the first and third aspects of the present invention, the push button of the changeover switch is formed on the inner side of the changeover recess from the changeover hole provided at the bottom of the changeover recess that is opened in the exposed portion of the housing and is recessed in a spherical shape. since projects, compared with the case where no protruded a push button of the changeover switch on the inside of the switching換凹portion, it is easy to press operation of selector switch according fingers, necessary to use a jig such as a driver to press operation of the change-over switch There is no. Further, according to the inventions of claims 1 and 3, the changeover switch has a strong pressing force required for accepting the pressing operation, and the pushbutton as viewed from the front, compared to any control switch. Since the area is small, erroneous operation of the changeover switch is further suppressed as compared with the case where the changeover switch and each control switch have the same pressing force and the area of the pushbutton as viewed from the front .

請求項２及び請求項３の発明によれば、切換スイッチの押釦は、前方から見た寸法形状と色との少なくとも一方が、いずれの制御スイッチの押釦とも異なっているので、切換スイッチの押釦と各制御スイッチの押釦とで、前方から見た寸法形状や色を全て共通とする場合に比べ、切換スイッチの押釦と制御スイッチの押釦との区別がつきやすくなり誤操作が抑制される。 According to the invention of claim 2 and claim 3, the push button of the changeover switch is different from the pushbutton of any of the control switches because at least one of the dimension shape and the color as viewed from the front is different from the pushbutton of the changeover switch. Compared with the case where the dimensional shape and color seen from the front are all the same for the push buttons of each control switch, it is easier to distinguish between the push button of the changeover switch and the push button of the control switch, thereby suppressing erroneous operations .

以下、本発明を実施するための最良の形態について、図面を参照しながら説明する。 The best mode for carrying out the present invention will be described below with reference to the drawings.

The address display 24 displays the addresses of the control switches 21 in a vertically aligned manner on the front surface. The front surface has a long rectangular shape on the front surface. It is mounted on the left and right positions between the control switch 21.

通信部１１及び制御部１４は、それぞれ周知技術によって実現可能であるので、詳細な図示並びに説明は省略する。 Since the communication unit 11 and the control unit 14 can be realized by well-known techniques, detailed illustration and description thereof are omitted.

There are four display holes 32j that expose the light emitting part of the indicator lamp 23 on the front surface, and address holes (not shown) that display the addresses of the control switches 21 displayed on the address display 24 one by one. It is installed in the front and back. As shown in FIG. 4, a switching recess 32k that is recessed in a spherical shape is provided in a range surrounding the switching hole 32i on the front surface of the cover 32, and the switching hole 32i is a central portion viewed from the front of the switching recess 32k. Open at the bottom.

さらに、カバー３２の前面にはシート状の銘板３４が貼着される。銘板３４は、例えば合成樹脂からなり、上２個の切換穴３２ｉと最も下の切換穴３２ｉと各表示穴３２ｊとの１個ずつに連通する７個の貫通穴が前後に貫設され、下から２番目の切換穴３２ｉと切換凹部３２ｋとをそれぞれ前方に開放する切欠が設けられた形状であって、アドレス穴の前側となる４箇所がそれぞれ透明とされている。また、カバー３２の前面には、銘板３４よりも僅かに大きい寸法形状とされた銘板凹部３２ｌが設けられており、銘板３４は銘板凹部３２ｌの内面によって位置決めされる。また、銘板凹部３２ｌの底面は平面形状であって、各制御スイッチ２１の押釦スイッチ及び切換スイッチ２２の押釦スイッチはそれぞれ銘板凹部３２ｌの底面に露出し、切換凹部３２ｋは銘板凹部３２ｌの底面に開口している。つまり、銘板凹部３２ｌの底面が請求項における露出部である。 Further, a sheet-like name plate 34 is attached to the front surface of the cover 32. The nameplate 34 is made of, for example, a synthetic resin, and has seven through holes communicating with the upper two switching holes 32i, the lowermost switching hole 32i, and the display holes 32j one after the other. The second switching hole 32i and the switching recess 32k are each provided with a notch that opens forward, and the four positions on the front side of the address holes are transparent. A nameplate recess 32l having a slightly larger size than the nameplate 34 is provided on the front surface of the cover 32, and the nameplate 34 is positioned by the inner surface of the nameplate recess 32l. Further, the bottom surface of the name plate recess 32l has a planar shape, and the push button switch of each control switch 21 and the push button switch of the changeover switch 22 are respectively exposed on the bottom surface of the name plate recess 32l, and the switching recess 32k opens to the bottom surface of the name plate recess 32l. is doing. That is, the bottom surface of the nameplate recess 32l is an exposed portion in the claims.

また、動作モードが制御モードとされて通常の操作端末器として使用される通常時には、ハウジング３の前側にはハンドルブロック４が取着される。ハンドルブロック４は、ハウジング３の左端部の前側に固定されるベース部４１と、それぞれ前方から見て長方形状であって左後端部が薄肉部を介してベース部４１に連結されることによりベース部４１に対して右端部を後方に弾性的に変位させることができる４個のハンドル部４２とを有するハンドル本体４０を備える。すなわち、図５及び図６に示すようにハンドルブロック４が装着された状態では、前方からハンドル部４２を押操作して後方へ変位させることにより、押操作されたハンドル部４２に応じた制御スイッチ２１の押釦がハンドル部４２によって押操作される。また、ハンドルブロック４は、前方から見てボックス穴３２ｄの上下位置までを覆う長方形状であって、ハンドルブロック４が取り付けられた状態では、切換凹部３２ｋや切換スイッチ２２の押釦はハンドルブロック４によって覆われ、切換スイッチ２２を押操作することはできない。つまり、ハンドルブロック４が取り付けられた状態では、見栄えが改善されるとともに、切換スイッチ２２の誤操作が防止される。ハンドル本体４０は例えば合成樹脂成型品からなる。 Further, at the normal time when the operation mode is set to the control mode and used as a normal operation terminal, the handle block 4 is attached to the front side of the housing 3. The handle block 4 has a base portion 41 fixed to the front side of the left end portion of the housing 3 and a rectangular shape when viewed from the front, and the left rear end portion is connected to the base portion 41 via a thin portion. A handle body 40 having four handle portions 42 capable of elastically displacing the right end portion backward with respect to the base portion 41 is provided. That is, in the state where the handle block 4 is mounted as shown in FIGS. 5 and 6, the control switch corresponding to the pushed handle part 42 is obtained by pushing the handle part 42 from the front and displacing it backward. 21 push buttons are pushed by the handle portion 42. Further, the handle block 4 has a rectangular shape that covers up to the vertical position of the box hole 32d when viewed from the front. When the handle block 4 is attached, the push button of the changeover recess 32k and the changeover switch 22 is moved by the handle block 4. The changeover switch 22 cannot be pushed. That is, in the state where the handle block 4 is attached, the appearance is improved and an erroneous operation of the changeover switch 22 is prevented. The handle body 40 is made of, for example, a synthetic resin molded product.

ハンドル本体４０において、ベース部４１の上下両端部と各ハンドル部４２の右端部とにはそれぞれハウジング３との結合のための係止凸部（図示せず）が突設されている。ハウジング３のカバー３２において、左上端部及び左下端部にはそれぞれベース部４１の係止凸部が挿入係止される係止穴３２ｍが前後に貫設されるとともに、右端部にはそれぞれ１個ずつのハンドル部４２の係止凸部が挿入係止される４個の係止穴３２ｎが上下に並べて前後に貫設されている。すなわち、ハンドル本体４０の各係止凸部がそれぞれハウジング３の係止穴３２ｍ，３２ｎに挿入係止されることにより、ハンドル本体４０はハウジング３に機械的に結合する。ここで、各ハンドル部４２の係止凸部及び対応する各係止穴３２ｎは、それぞれ制御スイッチ２１を押操作可能な程度にハンドル部４２の可動範囲を確保する形状とされている。 In the handle main body 40, locking protrusions (not shown) for coupling to the housing 3 are projected from both upper and lower end portions of the base portion 41 and right end portions of the respective handle portions 42. In the cover 32 of the housing 3, the upper left end and the lower left end are respectively provided with locking holes 32 m through which the locking protrusions of the base portion 41 are inserted and locked. Four locking holes 32n into which the locking projections of the individual handle portions 42 are inserted and locked are arranged vertically and penetrated in the front-rear direction. That is, the handle main body 40 is mechanically coupled to the housing 3 by inserting and locking the respective locking projections of the handle main body 40 into the locking holes 32 m and 32 n of the housing 3. Here, the locking projections of the handle portions 42 and the corresponding locking holes 32n are shaped to ensure the movable range of the handle portions 42 to the extent that the control switch 21 can be pushed.

また、ベース部４１の前面には上下に長い嵌合凹部４１ａが設けられるとともに嵌合凹部４１ａの底面において表示灯２３の前側となる４箇所にはそれぞれ窓穴４１ｂが前後に貫設されている。さらに、嵌合凹部４１ａには透光性を有する材料からなる表示窓４３が嵌め込まれており、ハンドルブロック４が取り付けられた状態でも各表示灯２３の光をそれぞれ表示窓４３を通じて前方から視認可能となっている。表示窓４３は例えば透明な合成樹脂からなる。 In addition, a long fitting recess 41a is provided on the front surface of the base portion 41, and window holes 41b are provided in front and rear at four locations on the bottom surface of the fitting recess 41a that are the front side of the indicator lamp 23, respectively. . Further, a display window 43 made of a translucent material is fitted in the fitting recess 41a, so that the light of each indicator lamp 23 can be viewed from the front through the display window 43 even when the handle block 4 is attached. It has become. The display window 43 is made of, for example, a transparent synthetic resin.

さらに、各ハンドル部４２の前面にはそれぞれ長方形状のカバー凹部４２ａが設けられるとともに、各カバー凹部４２ａの底面にはそれぞれカード凹部４２ｂが設けられていて、各ハンドル部４２には、例えば紙からなりカード凹部４２ｂに収納されるネームカード４４と、例えば透明な合成樹脂からなりカバー凹部４２ａに嵌合することによりハンドル部４２に対して固定されネームカード４４の脱落を防止するネームカバー４５を取付可能となっている。ネームカード４４には、例えばハンドル部４２によって押操作される制御スイッチ２１に対応付けられた負荷の名称が記入される。 Further, a rectangular cover concave portion 42a is provided on the front surface of each handle portion 42, and a card concave portion 42b is provided on the bottom surface of each cover concave portion 42a. A name card 44 housed in the card card recess 42b and a name cover 45 made of, for example, a transparent synthetic resin and fixed to the handle part 42 by being fitted into the cover recess 42a to prevent the name card 44 from falling off. It is possible. In the name card 44, for example, the name of the load associated with the control switch 21 pushed by the handle portion 42 is entered.

ここで、図１に示すように、各表示灯２３の発光部や、各制御スイッチ２１の押釦は、それぞれ銘板３４の前面よりも前方に突出する。一方、切換スイッチ２２の押釦は切換凹部３２ｋの内側に突出するものの、切換スイッチ２２の前端は銘板凹部３２ｌの底面よりも後側に位置する。 Here, as shown in FIG. 1, the light emitting portions of the indicator lamps 23 and the push buttons of the control switches 21 protrude forward from the front surface of the nameplate 34. On the other hand, although the pushbutton of the changeover switch 22 protrudes inside the changeover recess 32k, the front end of the changeover switch 22 is located behind the bottom surface of the nameplate recess 32l.

上記構成によれば、切換スイッチ２２の押釦の前端が、いずれの制御スイッチ２１の押釦の前端よりも後方に位置することになるから、切換スイッチ２２の押釦の前端と各制御スイッチ２１の押釦の前端とが互いに同じ前後位置に配置される場合に比べ、制御スイッチ２１を押操作する際の切換スイッチ２２の誤操作が抑制される。 According to the above configuration, since the front end of the push button of the changeover switch 22 is located behind the front end of the pushbutton of any control switch 21, the front end of the pushbutton of the changeover switch 22 and the pushbutton of each control switch 21 Compared with the case where the front ends are arranged at the same front-rear position, erroneous operation of the changeover switch 22 when the control switch 21 is pushed is suppressed.

また、切換スイッチ２２の押釦を内側に突出させる切換凹部３２ｋを設けていることにより、切換スイッチ２２の押釦を切換凹部３２ｋの内側に突出させない場合に比べ、手の指による切換スイッチ２２の押操作が容易となり、切換スイッチ２２の押操作にドライバー等の治具を用いる必要がない。なお、切換凹部３２ｋの形状及び大きさは、切換スイッチ２２の押釦の寸法形状や、切換スイッチ２２において押操作が受け付けられるために必要なストローク（押し込みの深さ）に応じて、適宜選択すればよい。 Further, by providing the switching recess 32k for projecting the push button of the changeover switch 22 inward, the push operation of the changeover switch 22 by the finger of the hand is performed compared to the case where the pushbutton of the changeover switch 22 is not projected inside the changeover recess 32k. Thus, it is not necessary to use a jig such as a screwdriver to push the changeover switch 22. The shape and size of the switching recess 32k can be selected as appropriate according to the size and shape of the push button of the changeover switch 22 and the stroke (pushing depth) required to accept the push operation at the changeover switch 22. Good.

なお、切換スイッチ２２の押釦において、前方から見た寸法形状と色との少なくとも一方が、いずれの制御スイッチ２１の押釦とも異なっているようにすれば、切換スイッチ２２の押釦と各制御スイッチ２１の押釦とで、前方から見た寸法形状や色を全て共通とする場合に比べ、使用者にとって切換スイッチ２２の押釦と制御スイッチ２１の押釦との区別がつきやすくなり誤操作が抑制されるから望ましい。 In addition, in the pushbutton of the changeover switch 22, if at least one of the dimension shape and the color viewed from the front is different from the pushbutton of any control switch 21, the pushbutton of the changeover switch 22 and each control switch 21 Compared to the case where the push button has the same dimensional shape and color as viewed from the front, it is desirable for the user to distinguish the push button of the changeover switch 22 from the push button of the control switch 21 and to prevent erroneous operation.

さらに、切換スイッチ２２において、押操作が受け付けられるために必要な押力をいずれの制御スイッチ２１よりも強くしたり、前方から見た押釦の面積をいずれの制御スイッチ２１よりも小さくしたりすれば、押操作が受け付けられるために必要な押力や、前方から見た押釦の面積を、切換スイッチ２２と各制御スイッチ２１とで共通とする場合に比べ、切換スイッチ２２の誤操作がより抑制されるから望ましい。 Further, in the changeover switch 22, if the pressing force necessary for accepting the pressing operation is made stronger than any control switch 21, or the area of the push button viewed from the front is made smaller than any control switch 21. Compared with the case where the changeover switch 22 and each control switch 21 have the same push force required for accepting the push operation and the area of the push button viewed from the front, erroneous operation of the changeover switch 22 is further suppressed. Desirable from.
