Claims

[Claims for Utility Model Registration] 1. A light-emitting element, an optical system for irradiating light emitted from the light-emitting element onto a barcode surface, and a light-receiving element that directs light reflected from the barcode surface. A head section having at least an optical system for making the light incident thereon can be detachably connected to the operating section, and the output optical signal or the output electric power of the head section can be connected to the operating section at the connection point between the head section and the operating section. A signal is input to the operating section via only one side from the center line of the connecting section, and the light receiving element or connection terminal of the operating section that receives the output optical signal or output electrical signal of the head section is located at the center line. A barcode reader characterized by being arranged symmetrically with respect to a line. 2. A light emitting element, an optical system for irradiating the light emitted from the light emitting element onto the barcode surface, and an optical system for making the light reflected from the barcode surface enter the light receiving element. At least a head section provided therein can be detachably connected to an operating section, and at a connecting section between the head section and the operating section, an output optical signal or an output electrical signal of the head section is connected to a center line of the connecting section. The same optical signal or electrical signal is output to the operating unit symmetrically with respect to
A barcode reader characterized in that a light-receiving element or connection terminal of the operating section that receives an output optical signal or an output electrical signal of the head section is provided only on one side of the center line.
