  The collective entrance machine 10 includes a control unit 11, an operation unit 12, a transmission / reception unit 13, and a call circuit 14.

  The control means 11 controls the entire collective entrance machine 10. The operation means 12 includes a numeric keypad, an enter button, etc. (not shown). The transmission / reception means 13 is connected to the control signal line Lc, transmits the dwelling unit number generated by the control means 11 through the operation of the operation means 12 to the housing information board of the corresponding dwelling unit, and unlocks from this housing information board Receive a signal. The control means 11 sends the unlocking signal received by the transmission / reception means 13 to a door control device (not shown) to open the audible door.

  The call circuit 14 is composed of a microphone and a speaker (not shown), and makes an interphone call with a designated house information panel via the audio signal line La.

  The management room master unit 30 includes a control unit 31, an operation unit 32, a display unit 33, a transmission / reception unit 34, a call unit 35, a timer 36, and an entrance history storage unit 37.

  The control means 31 controls the entire management room master unit 30.

  The operation means 32 is operated by an administrator in the management room and is provided with a numeric keypad. The display means 33 displays an unlocking signal output time, a dwelling unit number, whether or not there is a normal entrance, which will be described later. The transmission / reception means 34 is connected to the control signal line Lc and outputs a calling signal to the housing information panel of the dwelling unit designated using the operation means 32. The call means 35 is connected to the audio signal line La and makes an interphone call with the housing information panel of the dwelling unit designated using the operation means 32.

  The timer 35 outputs the mixed time and measures the time from a predetermined timing.

  The entrance history storage means 37 stores the unlock signal output time, dwelling unit number, presence / absence of a normal entrance signal, which will be described later.

  In addition, the above “normal entry signal” indicates that a visitor who has opened an automatic door by an unlocking signal by a resident of a designated residence through the collective entrance 10 (for example, within 10 minutes after the unlocking signal is output) ) This is a signal generated from the housing information board when the door phone of the entrance cordless handset is pushed after reaching the designated residence unit, and a signal indicating that the visitor has normally entered the apartment house.

  The “unlock signal output time” is the time when the unlock signal is output from the house information board, and is the time obtained from the timer 36.

  FIG. 3 is a diagram illustrating the visitor entrance list L1 stored in the entrance history storage unit 37 in the first embodiment.

  The visitor entrance list L1 is a list that is provided on the display means 33 with an “unlock signal output time” field, a “dwelling unit number” field, and a “normal entry” field.

  Next, the operation of the first embodiment will be described.

  First, when a visitor presses a call button (not shown) after a visitor designates a dwelling unit number via the numeric keypad 12 from the collective entrance 10, a dwelling unit is connected to the housing information board of the designated dwelling unit number via the transmission / reception means 13. A call signal with a number added as address information is output. At this time, the transmission / reception means 34 takes in the dwelling unit number designated from the calling signal and temporarily stores it. When the resident operates the unlock button after confirming the visitor by making an intercom call or the like on the house information board side, an unlock signal is output in response to the calling signal.

  When the unlocking signal is output in response to the calling signal, the control room master unit 30 recognizes that the visitor at the collective entrance is a visitor recognized by the resident and temporarily stores it. Immediately before, the designated house number is stored in the entrance history storage means 37.

  As shown in FIG. 3, the dwelling unit number stored in the admission history storage unit 37 is displayed on the display unit 33 of the management room master unit 30, so that the manager of the management room determines where the visitor has come. You can see if you are going into the apartment building towards the dwelling unit.

  By the way, if the visitor is a person who goes to the dwelling unit called by the collective entrance machine 10 such as an original courier company, the visitor visits the dwelling unit called by the collective entrance machine 10 and is provided in the entrance unit of the dwelling unit. It is necessary to operate the door phone and perform operations such as handing over the delivery. In this case, for example, when the house information board JB101 inputs a calling signal from the door phone 101, the house information board JB101 receives a confirmation signal indicating that the person who entered the house by the unlocking signal has visited the own residence, and the house information board JB101 Output to 30.

  When receiving the confirmation signal from the house information board JB101, the management room base unit 30 stores in the entrance history storage means 37 that the normal entrance has occurred. That is, as shown in FIG. 3, a circle is written in the row of the corresponding unit number and in the column of normal entrance.

  If the visitor is an intruder pretending to be a courier, the intruder will not press the door phone of the entrance unit installed in the unit, but will go to another unit. Therefore, the confirmation signal is not output, and therefore, the mark “◯” indicating that the entry has been made normally is not stored in the “normal entry” column in the visitor entry list L 1 stored in the entry history storage unit 37. In this case, the management room base unit 30 has an opportunity to catch an intruder who has entered the apartment house based on the time information and the like.

  That is, when the unlocking signal is output from the house information board, the entrance history storage unit 37 receives the signal by the transmission / reception unit 34 and outputs the unlocking signal output time that is the time when the unlocking signal is output. It functions as means for reading from the timer 36 and storing the unlock signal output time and the designated dwelling unit number.

  In addition, although the said Example is an Example which transmits a normal confirmation signal, when the visitor who entered from the collective entrance arrives at a predetermined | prescribed dwelling unit within 10 minutes, for example, and operates an entrance cordless handset, It may be as follows.

  On the housing information board side, after outputting the unlocking signal, the timer is started, and when the visitor operates the entrance cordless handset and receives the calling signal from the handset, the timer is stopped. You may make it measure the elapsed time until a visitor arrives at the said dwelling unit from a gathering entrance.

  Then, if the time required for arrival measured by the timer is also sent to the management room main unit and the time is recorded in the entrance history storage means, the administrator can make the visitor to another dwelling unit. It is possible to judge whether or not a detour is taken. For example, if the dwelling unit to be visited is on the second floor, etc., at a short distance from the main entrance, the “time required for arrival” should be short, but if this time takes, for example, 8 minutes, It can be inferred that he took a suspicious action such as detouring to some dwelling unit, and made another requirement.

  For this reason, the visitor can later inquire as he passes the administration room and exits the main entrance. In this way, measure the time it takes to arrive, record the time, and based on the length of the time, determine if the visitor is behaving in the housing complex. be able to.

  The entrance history storage means may also store the visitor image together with the unlock signal output time (entrance time). As the visitor image, an image taken by the one-shot camera of the collective entrance machine is transmitted to the management room base unit via a video signal line (not shown) and stored in the management room base unit. Thus, if the video information of visitors is stored, it is easy to find visitors who are not normally entered.
