Title: Tape-printing apparatus
Inventor: KOUSAI YOSHIHARU
IPC: B41J3/36
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To facilitate various settings and changes, etc., subsequent to the exchange of a tape, by switching to a process mode corresponding to a type of the tape on the basis of a judgment result of a type-of-tape judging means with using an output of a detecting means detecting the closure of a lid opening and closing a tape-mounting part as a trigger. SOLUTION: When a power source is turned on, a CPU 40 detects through a lid-open/close judgment interrupting process whether a lid is opened or closed. When the lid is closed, the CPU 40 sets a lid opening.closure flag to 1, and moreover detects a type of a set tape, thereby executing various settings and display changes. On the other hand, when the lid is opened/closed and a lid opening.closure detection switch detects the opening/closure, the CPU 40 judges whether or not the lid is closed. When the lid is closed, namely, the lid opening.closure flag LCF is equal to 1, a detection result by a tape type detection switch 32 is obtained. Thereafter, the CPU 40 changes settings and display contents. That is, a character size is changed in conformity with a tape width, and a warning is displayed when the conforming character size is not present.
