Control. Further, when an ON signal is input from the test mode valid switch 21, the operation panel device is switched to the test mode, thereby performing control for validating the switch operation of each operation switch 14a of the test panel 14. It is.

The control circuit 26 is a circuit that controls factory equipment and performs control according to switch operations in various modes.
The operation of switching the operation panel device of the electronic controller having such a configuration to various modes will be described.
First, when performing various settings for controlling the operation of factory equipment, the setting panel 13 is mounted on the operation surface 12 of the case 11 of the operation panel device shown in FIG. 1 in the state shown in FIG. When this mounting is performed, the operator presses the attachment gripping portions 13c on both side surfaces with his / her fingers from both sides and contracts them, and presses the projections 13d into the through holes 18 in this state while pressing them against the predetermined positions on the operation surface 12. . When the finger is released in this state, the attachment gripping portion 13c spreads, the claw fitting engages with the engaging portion of the operation surface 12, and the setting panel 13 is mounted in a fixed state.

  In this mounted state, the setting mode valid switch 20 is pressed by the protrusion 13d to be turned on, so that this on signal is input to the mode switching control circuit 22, thereby switching the operation panel device to the setting mode and setting. The switch operation of each operation switch 13a of the panel 13 is enabled. When switched to this setting mode, the LED in the setting mode on the display unit 17 of the operation surface 12 is lit. This confirms that the operator has entered the setting mode.

In this state, when the operator performs a desired setting operation with each operation switch 13 a of the setting panel 13, this operation command signal is input to the control circuit 26 via the wiring cable 25. The control circuit 26 performs setting control of factory equipment according to the input.
When various tests of factory equipment are performed after this setting is completed, the setting panel 13 is removed from the operation surface 12 while pressing the mounting grip 13c from both sides with fingers. Then, the test panel 14 is attached to the operation surface 12.

In this case, the operator presses and compresses the attachment grips 14c on both sides with fingers from both sides, and presses the projections 14d into the through holes 19 in this state while pressing them against the predetermined positions on the operation surface 12. When the finger is released in this state, the attachment gripping portion 14c spreads, the claw fitting engages with the engaging portion of the operation surface 12, and the test panel 14 is mounted in a fixed state.
In this mounted state, the test mode valid switch 21 is pressed by the protrusion 14d and turned on, so that this on signal is input to the mode switching control circuit 22, thereby switching the operation panel device to the test mode and performing the test. The switch operation of each operation switch 14a of the panel 14 becomes effective. When the test mode is switched, the LED in the setting mode on the display unit 17 of the operation surface 12 is lit. This confirms that the operator has entered the test mode.

In this state, when the operator performs a desired test operation with each operation switch 14 a of the test panel 14, this operation command signal is input to the control circuit 26 via the wiring cable 25. The control circuit 26 performs test control of factory equipment according to the input.
After confirming that the factory equipment is normal in this test, the test panel 14 is removed from the operation surface 12 to enter the normal operation mode. That is, since nothing is mounted on the operation surface 12, the setting mode valid switch 20 and the test mode valid switch 21 are turned off.

In this OFF state, the mode switching control circuit 22 is set to the normal operation mode, and the switch operation of each operation switch 16 on the operation surface 12 is enabled. In the normal operation mode, the LED in the normal operation mode on the display unit 17 of the operation surface 12 is lit. This confirms that the operator has entered the normal operation mode.
When the operator performs a desired driving operation with each operation switch 16 in this state, this operation command signal is input to the control circuit 26 via the wiring cable 25. The control circuit 26 controls the operation of the factory equipment according to the input.

  As described above, according to the operation panel device of the electronic controller of the present embodiment, the attachment panels 13 and 14 for various modes are provided separately from the operation surface 12 of the operation panel device. Each of the attachment panels 13 and 14 has a thin plate shape, and has various operation switches 13a and 14a on the surface and projections 13d and 14d on the back surface, and the projections 13d and 14d are arranged at different positions.

  In addition, a plurality of through holes 18 and 19 formed in the operation surface 12 of the operation panel device and corresponding to the projections 13d and 14d of the attachment panels 13 and 14 are disposed in the back of the through holes 18 and 19, respectively. A plurality of pressing switches (setting mode valid switch 20, test mode valid switch 21) and a protrusion 13d inserted into the corresponding through hole 18 when any of the attachment panels 13 (or 14) is attached to the operation surface 12 A mode switching control circuit (mode switching control) that performs mode switching in response to turning on of the setting mode valid switch 20 that is a pressed switch and activates the operation switch 13a of the attached attachment panel 13 Means) 22.

  Thus, for example, when setting the device, when the setting panel 13 that is an attachment panel for the setting mode is mounted on the operation surface, the protrusion 13d of the setting panel 13 is inserted into the predetermined through hole 18 of the operation surface 12. Then, the setting mode enable switch 20 at the back is pressed to turn it on. When this is turned on, the mode switching control circuit 22 switches to a setting mode corresponding to the setting mode valid switch 20 being turned on, and performs control to validate the operation switch 13a of the mounted setting panel 13. Thus, the operator can set the device by operating the switch on the setting panel.

  Similarly to this, when testing a device, by attaching the test panel 14 to the operation surface 12, the operator can test the device by operating the switch on the test panel 14. If an attachment panel for a mode for performing various other controls besides the setting and test modes is prepared, the operation is performed in various control modes without widening the operation surface 12 of the operation panel device body of the electronic controller. It becomes possible.

Therefore, various types of operation switches for performing mode switching and operation such as setting and testing can be arranged on the narrow operation surface 12 so as not to cause an erroneous operation with good operability.
More specifically, since any one of the attachment panels 13 and 14 for various modes is mounted on the operation surface 12 as described above, operation switches for various modes are provided on the conventional operation surface, and the mode changeover switch is used. There is no longer a large number of operation switches on the operation surface as in the configuration for switching modes. For this reason, visibility is improved and erroneous recognition is eliminated, so that the operability can be significantly improved.

In addition, since the area where the various operation switches 16 on the operation surface 12 are provided is the attachment area for each attachment panel 13, 14, one operation area on the operation surface 12 can be used more effectively. Thus, the operation surface 12 can be made to have a smaller area. Therefore, the entire operation panel device can be reduced in size, and the manufacturing cost can be reduced.
Moreover, since the attachment panels 13 and 14 are colored in different colors for each mode, there is no mistake when the operator makes a desired mode. Further, even after the attachment panels 13 and 14 are attached to the operation surface 12, it is possible to easily determine which mode the other operator is currently in. Furthermore, since the current mode can be accurately determined, erroneous operation can be prevented.

  Further, the attachment panels 13 and 14 may be provided with light emitting means such as LEDs that emit light in different colors for each of various modes when mounted on the operation surface 12. Although the configuration in this case is not illustrated, the LED is mounted on the surface of the attachment panels 13 and 14, and when the attachment panel 13 or 14 is mounted on the operation surface 12, the LED is in a state where power is supplied to the LED. Since it only needs to be connected to the power supply of the apparatus, it can be configured easily.

When the light emitting means is provided in this way, the operator can check the mode of the attachment panel 13 when the attachment panel (for example, 13) is attached to the operation surface 12, and other operators can check the mode after the attachment. It is possible to easily determine which mode is currently in progress, and to prevent erroneous operation.
In addition, when there are multiple operation panel devices for an electronic controller and the control functions are different for each operation panel device, a concave shape, a convex shape, an uneven shape, etc. are provided for each operation surface that is an attachment panel mounting surface of each operation panel device. In this way, mounting frames having different shapes are provided. And the shape of the outer periphery of each attachment panel is made into the shape fitted to the attachment frame of the operation surface of a mounting destination.

In this way, when multiple control panel devices for electronic controllers are mounted on a single control panel and the control functions are different for each control panel device, it is applicable except for an attachment panel with an outer peripheral shape that fits the mounting frame on the operation surface. Cannot be attached to the operation surface. Therefore, it is possible to prevent the attachment panel from being accidentally attached to another operation surface from the operation surface to be originally mounted.
In addition, in the said embodiment, although the through holes 18 and 19 were provided, it is good also as a structure which provides a film sheet | seat instead and presses the switches 20 and 21 with the projection parts 13d and 14d from this sheet | seat.
