Title: Method for loading tape cassette
Inventor: WATANABE HIDEYASU
IPC: G11B15/675
Filed: 1989-02-07
Abstract: PURPOSE:To enable an optimum position control by cutting off a power source for a motor in timing delayed by a decided time relative to a position signal showing a tape cassette position and operating a brake simultaneously. CONSTITUTION:When the position signal is sent out by a position detecting means 3, timing sending time is decided by a control means 5 in corresponding to a terminal voltage of a motor 4 at this time. Then, when this decided time has elased since the position signal is received, contacts 1 and 2 of a changeover circuit 7 are opened while a contact 3 is closed, so as to operate a dynamic brake which consumes electric power generated by the motor 4. By this method, even when an overrun distance is altered due to a secular change of a carrier mechanism 2 in friction, the optimum position control can always be performed.

Then data is finally printed on either a designated sheet or a selected sheet. Consequently, if data which exceeds the size of a sheet is received, the data is entered in the framework of a designated sheet without failure. It is also possible to print data which cannot be entered in the framework of a default sheet, positively in the framework of a sheet by automatic conversion of the sheet size.
