Code reader for reproducing information recorded as code pattern

摘要

A code reader holder comprises an upper cover, a lower cover, a volume controller, an inner speaker, a electric element mounting portion, a substrate, a battery, and a terminal section. The electric element mounting portion decodes a code read by the code reader to convert the code into an electric audio signal, and outputs the electric audio signal as audio data from the inner speaker. The audio data is output at a suitable volume level adjusted by the volume controller. The code reader body contains therein an imaging section mainly comprising a lens and a light-receiving sensor as an imaging element, an illumination section for irradiating the code, and a transmission section for transmitting information obtained by the imaging element to the electric element mounting portion in the code reader holder.
