<p>PURPOSE:To reproduce input data in the form of past input even after power-off by providing a memory, from which input data is supplied to a control part as reproduced input data, and a backup power source. CONSTITUTION:A control part 1 receives input data from a keyboard 2 and sends it to a computer 3. When a data read start switch provided in the control part 1 is depressed, the control part 1 sends input data to a data storage part 4 to store it there thereafter, and this operation is continued until an end switch is depressed or the storage part 4 is filled up. If a reproducing switch in the control part 1 is depressed when input data is lost in the computer 3, input data stored in the storage part 4 is read in the read-in order. This input data is supplied to the control part 1 as reproduced input data in the original form, and it is sent to the computer 3. A power supply part 5 supplies a supply voltage free from power failure so that contents of the storage part 4 are not lost at the time of power-off due to power failure.</p> |
