Lock-confirmation supporting device

Abstract

To provide a lock-confirmation supporting device which helps a user to do the lock confirmation with the senses of a human being easily and surely at the time right after the locking operation, and to do the lock reconfirmation easily after being locked. A lock-confirmation supporting device is constituted of a key holder portion ( 2 ) in which a key is held and out of which it is taken by a user for locking and an electronic clock portion ( 3 ) comprising a clock circuit, CPU, ROM, RAM and a display unit. The lock-confirmation supporting device generates a lock-confirmed signal upon the user's key-returned action right after the locking oepration. Upon the lock-confirmed signal, the lock-confirming device stores in the RAM of the electronic clock portion ( 3 ) the real time as the lock-confirmed time and informs the user of the lock-confirmed time by displaying it on a liquid crystal display unit ( 18 ). The lock-confirmed signal is generated by a key-taken out or key-returned sensor means, a locking sound detecting means including locking sound sensor, for example, a microphone ( 5 a ) and the like or manual input switch ( 22 ) provided in the key holder portion ( 2 ). The lock-confirmed time stored in the RAM is displayed on the liquid crystal display unit ( 18 ) by operating a reconfirmation switch ( 7 ) after locking.

1 . A lock-confirmation supporting device having a key holder in which a key is held and out of which it is taken by a user for locking, comprising: 
 a real time clock for measuring time,    a memory means for storing the lock-confirmed time,    a display means for displaying the lock-confirmed time,    a means for generating a lock-confirmed signal upon the user's key-returned action right after the locking operation,    a manual switch for inputting a reconfirming signal, and    a control means effective, upon the lock-confirmed signal, to store the real time measured by said real time clock as the lock-confirmed time in said memory means and to make said display means inform the user of the lock-confirmed time, and upon the reconfirming signal, to read the lock-confirmed time from said memory means and to make the display means inform the user of the lock-confirmed time.    
     
     
         2 . A lock-confirmation supporting device according to  claim 1  wherein said key holder has a pocket in which a key is held and out of which it is taken by a user for locking, and said means for generating a lock-confirmed signal includes a key-returned sensing switch which is positioned in the pocket and senses the moment when the key is returned to the pocket of the key holder.  
     
     
         3 . A lock-confirmation supporting device according to  claim 1  wherein said key holder has a case with a lid in which a key is held and of out which it is taken by a user for locking, and said means for generating a lock-confirmed signal includes a lid-open/close sensing switch which is positioned in the case and senses the moment when the lid is closed after the user returns the key to the case of the key holder.  
     
     
         4 . A lock-confirmation supporting device according to  claim 1  further comprising a speaker means for announcing the lock-confirmed time, and said control means effective, upon the lock-confirmed signal, to store the real time measured by said real time clock as the lock-confirmed time in said memory and to make said speaker means announce the lock-confirmed time, and upon the reconfirming signal, to read the lock-confirmed time from said memory means and to make the speaker means announce the lock-confirmed time  
     
     
         5 . A lock-confirmation supporting device having a key holder in which a key is held and of out which it is taken by a user for locking, comprising: 
 a real time clock means for measuring time,    a memory means for storing the lock-confirmed time,    an information means for informing the lock-confirmed time and the calling message,    a key-taken out sensing means for generating a key-taken out signal by sensing the moment when the user takes the key out of the key holder,    a calling message informing control means for making the information means inform the user of the calling message read out of the memory means upon the key-taken out signal,    a key-returned sensing means for generating a key-returned signal by sensing the moment when the user returns the key to the key holder,    a first confirmed time-informing control means for making the memory means store the real time measured by the real time clock means as the confirmed time, and for controlling the information means to inform the user of the confirmed time upon the key-returned signal,    a reconfirming signal means for inputting reconfirming signal, and    a second confirmed time-informing control means for making the information means inform the user of the confirmed time read out of said memory means upon the reconfirming signal.    
     
     
         6 . A lock-confirmation supporting device according to  claim 5  wherein said key holder has a pocket in which a key is held and out of which it is taken by a user for locking, and said means for generating a lock-confirmed signal includes a key-returned sensing switch which is positioned in the pocket and senses the moment when the key is returned to the pocket of the key holder.  
     
     
         7 . A lock-confirmation supporting device according to  claim 5  wherein said key holder has a case with a led in which a key is held and out of which it is taken by a user for locking, and said means for generating a lock-confirmed signal includes a lid-open/close sensing switch which is positioned in the case and senses the moment when the lid is closed after the user returns the key to the case of the key holder.  
     
     
         8 . A lock-confirmation supporting device according to  claim 5  wherein said calling message is the key-lock calling message.  
     
     
         9 . A lock-confirmation supporting device according to  claim 5  wherein said calling message is the safety check calling message.  
     
     
         10 . A lock-confirmation supporting device according to  claim 5  wherein the information means includes the liquid crystal display.  
     
     
         11 . A lock-confirmation supporting device according to  claim 5  wherein the information means includes the speaker.
