Abstract

PURPOSE:To prevent incorrect discrimination from occurring due to a operator error and to enhance operability, by moving an automatically set printing medium to a discriminating position, in a printer for a passbook, a bond or the like. CONSTITUTION:When the printing medium MED is set on the printer by the operator and is detected by a photosensor PS1, a main controlling part 5 turns a belt by a drive-controlling part 9, and when the medium MED introduced reaches a point (a), a timer 10 is set by a signal from a sensor PS3. According to presence/absence signals from sensors PS2-PS4 at a point (b) constituting a time position, a discriminating circuit 6 discriminates, and a discrimination signal and checking data from a memory circuit 8 are compared with each other by a comparing circuit 7, thereby checking whether the medium MED is the one to be printed. Accordingly, misdiscrimination is prevented from occurring due to a operator error, the operator is relieved of operation, and the kind of medium can be accurately discriminated.
