The present invention relates to a dual quantity display device and a method of controlling the same, including a pulse input means for picking up a take-up reel pulse of a reel sensor, a supply reel pulse, and a control pulse of an image head when the tape is running; Display mode selection means for arbitrarily selecting the reel pulse display mode and the control pulse display mode, and the take-up reel pulse, the supply pulse and the control pulse inputted from the pulse input means are always read and calculated, and the result is calculated. In this state, it is possible to determine whether the display mode or control pulse is currently selected and An automatic switching means for automatically switching the tape travel amount display mode by controlling the OSD in a display mode, and controlling the OSD to display a reel pulse count or a control pulse count amount on a screen in text by a control signal of the automatic switch means; OSD control means, and on-screen display means for displaying on the screen so that the user can recognize the character of the tape running amount controlled by the OSD control means, and also the reel pulse and the control pulse read from the tape The first step of counting the tape travel amount and maintaining the result; and the reel pulse count amount if the currently selected display mode is the display mode by the reel pulse after performing the first step. The second stage of controlling the OSD to display on the screen and checking whether there is an input of control pulse if it is not in display mode by reel pulse. If the control pulse does not exist as a result of the check in the second step, the current display mode is switched to the display mode by the reel pulse and returns to the display mode check step in the second step. Check the to control the OSD to display the control pulse count amount by the linear time counter if not in the dual display mode, and control the OSD to display the control pulse count and the reel pulse count on the screen simultaneously in the dual display mode. It is done in a third step.
