ABSTRACT:
Apparatus for sharing entrance of a multiple dwelling house. The apparatus controls the visit and/or calling of a door-to-door sales agent. The apparatus automatically receives delivery of goods addressed to one of the dwelling units regardless of the presence or absence of a resident. Registered agents, such as residents and agents granted access, use an IC card that carries identification information to gain access of a shared entrance. For each dwelling unit, a registered agent likewise uses the IC card to send family identification information or agent identification information to a door phone apparatus, thereby unlocking the door lock of the entrance for a family member.
