An invention of a cordless telephone is disclosed. This cordless telephone detects whether or not a charging voltage is applied to the charging terminal of the handset, and when the handset is switched from a state where the charging voltage is applied to the charging terminal of the handset to a state where the charging voltage is not applied, It is determined that the line has been picked up and is in an off-hook state, and the line with the base unit is captured.

  By the way, in a cordless telephone device having a quick call function, the line is captured when the phone is picked up from the charger in order to receive the phone number of the other party using the number display service and confirm the other party's phone number. There was a problem that it was necessary to talk to the other party who did not want to answer. In addition, when an external line is received, the slave unit is picked up from the charger, the line is captured, and then the slave unit is accidentally dropped on the charger to be in a charged state, the line is disconnected.

As a cordless telephone that solves such problems, for example, an invention of a cordless telephone having a quick call function disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2000-341401) is known. When the cordless phone is uncharged, that is, when the cordless handset is taken off the charger and goes off-hook, the cordless telephone detects the incoming / outgoing call on the outside line, and the cordless telephone detects the incoming call on the outside line. Is detected (ie, when an incoming call is received), the line is not captured, and the quick call function is disabled. On the other hand, if the detection detects a non-incoming outside line (ie, when an outgoing call is detected), the line is captured. The quick call function is configured to work.
