Claims

[Scope of utility model registration request]

Multiple telephones share multiple lines and send out dial pulses using push-button dialing, and when making a speed dial call, the pulses are input into the memory of the integrated circuit by pressing a designated dial button. In an out-pulse button telephone device that can automatically send out a telephone number, power is supplied to the memory of the integrated circuit under normal conditions by supplying a battery through a hook switch contact, and when a line selection switch is pressed. When not in the off-hook state, the battery is supplied via the piezoelectric switch for line selection, and when the line selection switch is pressed and on-hook, the battery is supplied via the hook switch contact and the line is selected. When the line selection button is pressed and the line is off-hook, power is supplied from the line, and when the line selection button is pressed or restored, and when making a call when off-hook or on-hook, power is supplied from the line after the battery is disconnected. A memory holding circuit for an outpulse button telephone device, characterized in that when a call is terminated, a battery is supplied after the line power is cut off.
