Description

  The present invention relates to a panel mounting structure for an electronic device case, and in particular, places a burden on the user not only for a single unit case of an amplifier unit in an amplifier-separated type sensor but also for a case row in which a plurality of unit cases are connected. The present invention relates to a panel mounting structure for an electronic device case that can be easily and beautifully mounted on a panel.

  For example, in a factory FA, various sensors such as a photoelectric sensor, a proximity sensor, an ultrasonic sensor, and a displacement sensor are used to detect the presence and position of an object. In terms of object measurement distance and detection accuracy, photoelectric sensors, particularly optical fiber photoelectric sensors, tend to be widely used.

  By the way, in recent years, in order to enable compact accommodation in a control panel or the like, and in order to facilitate installation in a narrow measurement environment, this type of photoelectric sensor includes a sensor head and an amplifier. There is a so-called amplifier-separated photoelectric sensor that is separated from each other.

  According to such an amplifier-separated photoelectric sensor, the detection head unit itself is arranged close to the detection target object, while the amplifier unit can be incorporated in a control panel familiar to an operator who is easy to perform maintenance, etc. Since the amplifier units can be closely arranged adjacent to each other, the accommodation space can be easily made compact. In addition, since the sensor head portion can also be configured in a small size, it has various advantages such as being easily incorporated into a narrow space near the detection target (see, for example, Patent Document 1).

  In the amplifier-separated photoelectric sensor described above, an amplifier unit array formed by connecting one or more amplifier units via a DIN rail or the like is disposed in the control panel. In recent years, the LCD panel is provided with a liquid crystal display, and an openable / closable operation cover is provided to change the measurement conditions by opening the operation cover. A panel mounting structure has been sought from the user side, which has been established and the amplifier unit is fitted into the opening and fixed in a manner that allows it to be fixed.

Conventionally, for example, as shown in Patent Document 2, in order to attach a display such as a liquid crystal display to a panel, a liquid crystal display is provided with a frame-like mounting frame that is attached to the window edge of a display window formed on the panel. For example, in the case of adding a unit case such as an amplifier unit in an amplifier-separated photoelectric sensor, a dedicated structure that assumes panel mounting is known. Therefore, it is necessary to create a special mounting mechanism on the user side.
