In the case the die cut label sheet is mounted, by detection of threshold voltage of output signal of the photo sensor, each label provisionally adhered to a front surface of the die cut label sheet is fed to a print start position. In the case the unfixed-length roll sheet is mounted, if the feeding speed is less than 40 mm/sec, by detection of threshold voltage of output signal of the photo sensor, the feeding state of unfixed-length roll sheet is judged, or if the feeding speed is not less than 40 mm/sec, on the basis of voltage change for the predetermined potential difference portion of output signal of the photo sensor, the feeding state of unfixed-length roll sheet is judged.

Tape printer

An electronic apparatus which detects when a battery having a different characteristic is mixed in a plurality of batteries accommodated therein. An average voltage Vper battery of plural batteries connected in series and an average voltage Vper battery at a connecting point halfway of those connected batteries are detected. A difference in voltage |V&#x2212;V| between the average voltage Vand average voltage Vis compared with a tolerable voltage difference &#x394;V. If it is determined that a battery having a different characteristic is mixed, the operation of the apparatus is interrupted and an alarm is displayed or the supply of power is shut down.
