Send as.

On the other hand, when simply calculating the number of transfer sheets or performing other calculations, first, the calculation mode command means 7 sends the calculation mode command d to the main control section 2. As a result, the calculation mode is set, and when the numerical input means 1a and the calculation command means 1b issue a desired calculation command to the calculation means 2a as described above, a numerical signal a is sent out, and the calculated value is displayed on the display 3 as a display signal g. Sent as .

In this figure, A indicates the original image length, and B indicates the formed image length.

When performing normal calculations, for example calculating the number of sheets (13x4+3x7), press the calculation key 15 to set the calculation mode, and use the numeric keypad 11a as you would with an electronic desk calculator.
When the keys 12 and 12 are operated in the above calculation order, the calculation result "73" is displayed on the 1 display 3.

When calculating the magnification for forming one image, for example, if the original image length A is 10++v and the formed image length B after image formation is 15 layers, first press the calculation key 15 to set the calculation mode. Then, rlJ the formed image 1B=15 using the numeric keypad 11a.

Enter "5" in this order. This numerical input value is displayed on the display 3. Next, press the ÷ key 12d in the function key 12, and then set the original image length A=lO to "1" using the numeric keypad 11a.

If you input the numerical values in the order of rQJ, the calculated value rO, 66...
" is displayed on the display 3. At this time, when the operator presses the magnification key 13, a magnification sending command C is input to the main control unit 2, and a magnification signal e is sent to the optical system unit 5, which sets the calculated value ro, 66'' as the image forming magnification. Ru. .
