Abstract
A tabletop type optical information reader has a projection unit, a trigger unit, a decode unit, a data processing unit, a memory unit, and a switch unit. The projection unit projects light to a read object. The trigger unit instructs the projection unit for projecting light. The decode unit receives reflected light from the read object and decodes information contained in the read object. The data processing unit processes the decoded data provided by the decode unit. The memory unit stores at least one function that can be set in the optical information reader. The switch unit calls the function to be set.
Claims20
An optical information reader of a tabletop type comprising:
- a projection unit for projecting light to a read object;
- a trigger unit for instructing said projection unit for projecting light;
- a decode unit for receiving reflected light from the read object and decoding information contained in the read object;
- a memory unit for storing at least one preset function that can be set in said optical information reader;
- a switch unit for calling the function to be set;
- and
- a data processing unit for performing processing corresponding to the function to be set called by said switch unit.
An optical information reading method using an optical information reader having a projection unit, a trigger unit, a memory unit and a switch unit, said comprising:
- selecting at least one function that can be set in the optical information reader and storing the selected function in the memory unit;
- projecting light to a read object from the projection unit in response to an instruction of the trigger unit;
- receiving reflected light from the read object and decoding information contained in the read object;
- calling said selected operation function from the memory unit by the switch unit;
- and
- performing processing corresponding to the function to be set called by the switch unit.
An optical information reader comprising:
- a projection unit for projecting light to a read object;
- a trigger unit for ordering said light projecting to said projection unit;
- a decode unit for receiving reflected light from said read object and decoding information contained in the read object;
- a data processing unit for processing a data corresponding to said decoded information and decoded by said decode unit;
- a memory unit for setting up at least one operation mode to determining an operation state of said optical information reader and for providing selectable operation function corresponding to each of said operation mode;
- an operation mode switching means for selecting said operation mode setup into said memory unit;
- and
- an switching means for executing said selected operation function corresponding to the selected operation mode and provided from said trigger unit separately.
An operation method of an optical information reader having a switching means for providing a desired operation function and executing said provided operation function, said method comprising:
- a setup step for setting at least one operation mode to determine an operation state of said optical information reader;
- a providing step for providing a selectable operation function corresponding to said operation mode;
- a selection step for selecting said operation mode by said switching means;
- and
- an executing step for executing said provided operation function corresponding to said selected operation mode.
An operation method of an optical information reader having a switching means for setting an operation mode from all of registered operation modes to decide an operation state of said optical information reader, providing a desired operation function corresponding to said set operation mode and executing said provided operation function, said method comprising:
- a setup step for setting at least one operation mode to determine an operation state of said optical information reader based on a first predetermined pressed time of said switching means;
- a providing step for providing a selectable operation function corresponding to said operation mode;
- a selection step for selecting said operation mode by said switching means;
- and
- an execution step for executing said provided operation function corresponding to said selected operation mode based on a second predetermined pressed time being different from said first predetermined pressed time.
