Abstract

PURPOSE:To prevent the driving electric power for the driving elements such as a thermal head, etc. from changing abruptly during operations and also prevent damages due to miss operations by constituting so that an external power supply unit can not be inserted to a connecting terminal unless the primary cell is disconnected when the condition is to be transferred from the use of the primary cell to the use of the external power supply unit. CONSTITUTION:Cell contacts 11, 12 are arranged on the side wall of a cell storage chamber 10 formed on the rear of a desktop electronic calculator. A cell cover 13 is fitted to a case 1 in one body by coupling a latch piece 13a with a latch hole 14 of the housing case 1 so as to fix the cell in the cell storage chamber 10. A connecting terminal 15 in which an output plug 9 of the external power supply unit is to be inserted is also provided on the side wall of the cell storage chamber 10. Therefore, when the electric power is to be supplied to the desktop electronic calculator-printer from the external power supply unit, the output plug 9 can not be inserted into the connection terminal 15 unless the cell in the cell storage chamber 10 is disconnected. Thereby, when the electric power supply is to be transferred from the use of the primary cell to the use of the external power supply unit, the power source of the desktop electronic calculator-printer is inevitably turned off before the output plug 9 is inserted into the connecting terminal 15.
