Abstract: An optical reading system including a warning sound for preventing theft of a portable optical reading apparatus (scanner). A timer is activated when movement of the scanner is detected by a movement detection device mounted on the scanner, indicating that the scanner has been lifted (moved) from a stationary condition. A user determination unit determines whether the movement of the scanner is caused by an authorized user. When the user is an authorized person, a timer is reset. When the timer is not reset during a predetermined time period, a warning sound is generated at a sound level which changes from a low sound level to a loud sound level over a period of time unless a predetermined operation is performed. In one embodiment, a second warning sound is generated at a stationary receiving station when the scanner does not respond to a polling signal.

Abstract: After serial signals output from a CCD sensor are amplified, a peak value of white levels corresponding to the space portions of bar codes is held by a peak hold circuit, and then the held peak value is converted into a digital value by an analog-to-digital conversion circuit. The value obtained by multiplying accumulation time data from the CCD sensor by the target value of the white level peak value is divided by the digital value. The next accumulation time of the CCD sensor is set on the basis of the result of this division. In this way, the sensitivity of the scanner is adjusted.

Abstract: A circuit for adjusting the sensitivity of an optical character reader in which light is applied to an information-recorded material by an LED array and the information is read by a line sensor. The optical character reader is switched to a sensitivity adjusting mode. It reads a reference material having uniform reflectivity on the surface. The read signal is A/D converted and the microcomputer 10 detects a discrepancy between the amounts of light depending on the different portions of the line sensor. Based upon the detection, the microcomputer sets the applying time of driving currents to the respective LEDs so that the light is uniformly applied to the reference material. The set value is stored in a memory. Thereafter, since the amounts of light from the LEDs of the LED array are adjusted according to the set value, the amount of the reflected light to the line sensor 5 can be uniform. Thus, a series analog voltage accurately responding to the darkness and brightness of the information can be obtained.
