Abstract
A bar code reader includes a first circuit board on which a photodiode, which receives light reflected from a bar code, is installed and a second circuit board on which a processing unit that processes a signal output from the photodiode. The position at which the first circuit board is placed can be decided irrespective of the position at which the second circuit board is placed. The first circuit board is placed at a position that is most suitable for receiving light reflected from the bar code.
Claims18
A bar-code reader comprising:
- a first arrangement to mount a converting element that receives a light reflected from a bar code and converts the light received to an electric signal;
- and
- a second arrangement to mount a processing unit that reproduces the bar code from the electric signal.
A method of reading a bar code using a bar code reader that includes a first processor that reproduces a pattern of the bar code from a electric signal, the first processor having a first memory unit;
- a second processor that reproduces the bar code based on the pattern, the second processor having a second memory unit;
- and a storage unit that stores a first computer program and a second computer program, comprising:
- the first processor reading the first computer program from the storage unit, storing the first computer program into the first memory unit, and executing the first computer program to reproduce the pattern;
- and
- the first processor reading the second computer program from the storage unit and storing the second computer program into the second memory unit of the second processor, and the second processor executing the second computer program to reproduce the bar code.
