Claims

[Scope of utility model registration request]

A plurality of recording electrodes and a return electrode common to each of the recording electrodes are brought into contact with an ink ribbon for transfer, and electricity is selectively applied between each of the recording electrodes and the return electrode to transfer the ink of the ink ribbon. In an electrical transfer recording device that performs recording, the ink ribbon is provided at a location spaced apart in the width direction, with a distance equal to or greater than a vertical deviation width when the ink ribbon runs with respect to each of the recording electrodes. It is located in front of the monitor electrode and a distance sufficient to print at least one character from the end of the ink ribbon, and is formed at a portion facing only the monitor electrode, and has a resistance value different from that of other recording areas. a detection area of the ink ribbon, a termination detection circuit that conducts current between the monitor electrode and the return electrode and detects the detection area of the ink ribbon based on a change in resistance value; An electrical transfer recording device comprising: a control circuit that continues a recording operation until printing of at least one character is completed.
