Abstract

PURPOSE:To set a recording medium in a correct position by deciding erroneous detection owing to the hole etc. of the medium at the time of detecting and setting the recording medium in the prescribed position. CONSTITUTION:When the hole or the like of a recording medium is detected with a sensor, the absence of the medium 10 is detected and when the medium is detected again within N scale from this point, a counter 23 is reset by the rise signal after the fall period in follow up to the detection of the hole like FF output, whereby the counting of N scale is carried out again. Hence, no matter how many of holes are in the passage of the sensor 2, the above-mentioned procedure is merely repeated, and as far as the period where there is no medium detected by the sensor 2 is within N scale, it is decided to be a hole and is removed. When the N-scale counting is finished, this is the prescribed position and a motor driving pulse is stopped and set.
