PURPOSE: To prevent generation of hitch and superpostion by detecting a stencil paper by means of a photoelectric switch in each conveyance range divided in pluralities and inter-connecting the said detection with driving of the conveyance band, in an automatic spraying marking apparatus.
CONSTITUTION: When a stencil paper does not exist in a conveyance range 1 or driving apparatuses M1 and M2 are in operation for conveyance from the range 1 to a range 2, the next stencil paper is prepared in a punching machine 16. After preparation, the paper is sent into the range 1, and a photoelectric switch A detects the paper. If the preceding paper does not exist in the next range 2 or the paper is being conveyed to a range 3, the driving apparatuses M1 and M2 are operated to feed the paper into the range 2. Similarly in the following ranges, the paper is conveyed into a spraying apparatus 17 in succession under confirmation.
