Claims

[Claims for Utility Model Registration] 1. In an intercom device with an unlocking function that can be unlocked via a controller from a base unit and a slave unit in which various operation switches are housed, A numeric keypad switch for inputting a signal for the numeric keypad switch, and an illumination lamp installed near the numeric keypad switch to illuminate the numeric keypad switch, and a signal sent from the numeric keypad switch to be encoded in the controller. an encoder; a coincidence detection circuit that detects whether a signal for unlocking from the encoder matches a preset signal;
an unlocking output circuit for unlocking the lock based on the coincidence signal of the coincidence detection circuit; and a lighting signal discrimination circuit for discriminating whether the output from the ±encoder is a signal for lighting the illumination lamp. An intercom device with an unlocking function, further comprising a lighting signal output circuit that turns on the lighting lamp for a predetermined period of time based on the output of the lighting signal discrimination circuit. 2. The intercom device with an unlocking function according to claim 1, wherein the signal for turning on the illumination light is a signal sent in conjunction with one of the ten key switches. 3. The solution set forth in claim 1 of the utility model registration, characterized in that the signal for turning on the lighting lamp is a signal sent in conjunction with the opening/closing operation of a door for housing the numeric keypad switch. Intercom device with lock function.
