By pressing the operation switch 2a during key locking, the operation guidance means 5a indicates the key lock release operation, and key lock can be released only when the operation input which coincides with the release operation is performed. Therefore, the unintended operation of the electrical apparatus can be prevented, and the key lock release operation by the stationary operation due to chronic state can be suppressed because the operations require thinking.

Description

  The present invention relates to a method for releasing a key lock (operation invalid) used in an operation unit of an electric device.

  Conventionally, as this type of operation unit key lock, the device has a child lock switch, an LED indicator lamp, and a warning buzzer. By pressing the child lock switch for a predetermined time (for example, about 3 seconds), an operation button is provided. In this key lock state, the child lock switch is continuously pressed for a predetermined time (for example, about 3 seconds) to return to the normal mode.

  In addition, if any operation switch is pressed while the key is locked, there is a warning buzzer and a blinking display with an LED indicator that the key is locked, preventing unintended operation of the device. (For example, refer to Patent Document 1).

  As another operation unit key lock, a predetermined operation switch is pressed in a specific pattern to enter a key lock state, and in this key lock state, the predetermined operation switch is pressed in a specific pattern to release the key lock. The specific pattern mentioned here means that a plurality of different operation switches are pressed simultaneously or sequentially [multiple press], and one operation switch is continuously pressed for a predetermined time (for example, 2 seconds). Or, it means “continuous press”, which means that a plurality of different operation switches are pressed simultaneously or sequentially for a predetermined time, and it is an unintended device by complicating key lock start and release operations. There is one that strengthens the prevention of the operation (for example, see Patent Document 2).
