Abstract

PURPOSE:To save handling time required for inputting operation by detecting automatically the sort of a slip at the first time to read the slip and setting storage. CONSTITUTION:At the time of a form information input mode, the shape of a regular slip 1 to be read is read by an optical character reading sensor 2, and size in length and width is calculated by a size calculating means 4, and is stored and set in a size register 5. Besides, light transmitted through the slip 1 to be read is detected by a transmitted light sensor 6, and its thickness is obtained by a thickness calculating means 7, and is stored and set in a thickness register 8. Next, when a usual form carrying mode is started, a slip discriminating means 9 compares the output of the size calculating means and the stored set value of the size register 5, and simultaneously, compares the output of the thickness calculating means and the stored set value of the thickness register 8, and discriminates the identity of the slip 1 to be read. Thus, the work of an operator is simplified.
