Claims

[Scope of utility model registration request]

A character selection mechanism that selects characters to be printed, a carriage feeding mechanism that selects a printing position, a printing mechanism that prints the characters selected by the character selection mechanism at the printing positions selected by the carriage feeding mechanism, and beginning and end ends of printing. In the printing device, the control circuit includes a margin set mechanism for setting the number of characters to be printed and a margin set mechanism for setting the number of characters to be printed, a keyboard, and a control circuit for controlling the character selection mechanism, the carriage feeding mechanism, and the printing mechanism based on input from the keyboard. a CPU that calculates the number of remaining characters based on the starting and ending values set by the CPU;
It is characterized by being equipped with a buzzer mechanism that indicates the number of remaining characters that can be printed by generating a buzzer sound of a different frequency, volume, or number of intermittent sounds at printing positions corresponding to a plurality of preset numbers of remaining characters based on the output of U. printing device.
