Abstract
A handy type bar code reader for reading bar codes, including within a body case an LED base for radiating light used for reading bar codes; a condenser lens for condensing the light radiated from the LED base and conducting the condensed light to the bar codes; a focusing optical system for focusing a bar code image based on the light reflected from the bar codes in a predetermined read position, the focusing optical system comprising a reflecting mirror and a focusing lens; and an image sensor for reading the focused bar code image. The LED base and a condenser lens are held within the body case in a non-fixed state with respect to the body case.
Claims15
A handy type bar code reader for reading bar codes, comprising:
- light radiating means for radiating light used for reading bar codes;
- condenser lens means for condensing the light radiated by said light radiating means and directing the condensed light to the bar codes;
- optical means for focusing a bar code image reflected from the bar codes at a predetermined read position;
- reading means for reading the focused bar code image;
- a body case for carrying said light radiating means, said condenser lens means, said optical means and said reading means in a predetermined relation of arrangement;
- and
- holding means for holding said light radiating means and said condenser lens means in a moveable relation with respect to said body case.
A handy type bar code reader for reading bar codes, comprising:
- light radiating means for radiating light used for reading bar codes;
- condenser lens means for condensing the light radiated by said light radiating means and directing the condensed light to the bar codes;
- optical means for focusing a bar code image reflected from the bar codes at a predetermined read position;
- reading means for reading the focused bar code image;
- a body case for carrying said light radiating means, said condenser lens means, said optical means and said reading means in a predetermined relation of arrangement, said body case comprising a grip portion and a front end portion, said front end portion having a light radiation window adapted to be positioned in facing relation to the bar codes;
- and
- holding means, fixed to the grip portion side of said body case and having an arm extending in suspension within said body case from said grip portion to a position near said light radiation window, for holding said light radiating means and said condenser lens means in a predetermined positional relation with respect to one another and in a moveable relation with respect to the body case.
A handy type bar code reader for reading bar codes, comprising:
- light radiating means for radiating light used for reading bar codes;
- condenser lens means for condensing the light radiated by said light radiating means and conducting the condensed light to the bar codes;
- optical means for focusing a bar code image reflected from the bar codes at a predetermined read position;
- reading means for reading the focused bar code image;
- a body case for holding therein said light radiating means, said condenser lens means, said optical means and said reading means in a predetermined relation of arrangement;
- and
- holding means, disposed within said body case and having a slot formed in a thickness direction of the body case, for slidably holding said light radiating means and said condenser lens means in said slot so that the light radiating means and the condenser lens means are held in non-fixed abutment with the body case.
