A portable terminal apparatus, comprising:

• an apparatus body;
• an inputting section provided on said apparatus body for inputting processing information including data and an operation instruction;
• an optical reading unit mounted on said apparatus body for irradiating light upon a reading object and receiving reflected light from the reading object to obtain read information of the reading object, said portable terminal apparatus being additionally provided with a reading function as said optical reading unit is mounted integrally on said apparatus body;
• a trigger key allocated on said inputting section of said apparatus body of being manually operated to start a reading operation by said optical reading unit;
• a register for storing trigger key operation information when said trigger key is operated;
• a reading operation driving section for causing said optical reading unit to perform the reading operation while the trigger key operation information is stored in said register;
• a timer for counting a time elapsed after the trigger key operation information is stored into said register;
• and
• a resetting processing section for erasing the trigger key operation information stored in said register when the elapsed time counted by said timer exceeds a supervisory time or when read information of the reading object is obtained by the reading operation of said optical reading unit within the supervisory time.
