Claims

[Claims for Utility Model Registration] A main body having a reading reference surface that can be stably placed on a sheet with a bar code marked thereon, and a window formed on the reference surface for passing light, and a light emitting element. an optical lens disposed so as to condense the light from the light emitting element onto the surface of the sheet outside the window; and an optical lens disposed between the light emitting element and the optical lens, transmitting the light from the light emitting element; a half mirror that reflects light from an optical lens in a certain direction; a light receiving element disposed at a position where the light reflected on the surface of the sheet forms an image through the optical lens and the half mirror; and a reading mode. decoding means for generating a code signal corresponding to the barcode based on the output signal of the light-receiving element; and storage means for inputting the code signal obtained from the decoding means and outputting the code signal during transmission mode. a transmitting light emitting drive means for modulating the code signal output from the storage means and supplying the resulting modulated signal to the light emitting element as a transmitting light emitting drive signal; A barcode reader with a transmission function, comprising: a reading light emitting drive unit that supplies a drive signal to the light emitting element; and a mode switching unit that switches between the reading mode and the transmission mode.
