Code reading device and program
On a display window that displays code patterns that are read at a time, a code reading device allows the code pattern that is successfully decoded to be visually confirmed with ease. In a handy terminal, when an image scanner reads code patterns at a time in response to a trigger operation, a CPU performs decoding processes for each code pattern and determines whether the decoding processes have been successfully completed or not based on the decoding results so as to display an identifying mark indicating the determination result in association with the image of each code pattern.
1. A code reading device comprising:
a memory configured to store a first identification mark indicating that a code pattern is selected as a decoding target and a second identification mark indicating that a code pattern has been successfully decoded;
a code pattern display device which, when a plurality of code patterns are read at a time in response to a code reading instruction, displays images of the code patterns;
a selector which allows a user to arbitrarily select, on a display window that displays the images of the code patterns, whether or not each of the code patterns is selected as a decoding target;
a notification device which noticeably displays, based on a user selection via the selector, the first identification mark superimposed on the image of a code pattern that has been selected as a decoding target; and
a decoding processor which decodes each code pattern that has been selected as a decoding target when a decode instruction is received after the notification device noticeably displays the first identification mark, and which noticeably displays, based on a result of decoding, the second identification mark superimposed on the image of a code pattern that has been selected as a decoding target and has been successfully decoded.
2. The code reading device according to claim 1 , wherein the memory is configured to store a third identification mark indicating that a code pattern is not selected as a decoding target; and
wherein the notification device noticeably displays the third identification mark superimposed on the image of a code pattern that has not been selected as a decoding target.
3. The code reading device according to claim 2 , wherein the memory is configured to store a fourth identification mark indicating that a code pattern has not been successfully decoded; and
wherein the decoding processor noticeably displays, based on the result of decoding, the fourth identification mark superimposed on the image of a code pattern that has been selected as a decoding target and has not been successfully decoded.
4. A computer readable recording medium having a computer program stored thereon that is executable by a computer of a device comprising a memory configured to store a first identification mark indicating that a code pattern is selected as a decoding target and a second identification mark indicating that a code pattern has been successfully decoded, wherein the computer program is executable by the computer to cause the computer to perform functions comprising:
when a plurality of code patterns are read at a time in response to a code reading instruction, displaying images of the code patterns;
allowing a user to arbitrarily select, on a display window that displays the images of the code patterns, whether or not each of the code patterns is selected as a decoding target;
noticeably displaying, based on a user selection, the first identification mark superimposed on the image of a code pattern that has been selected as a decoding target;
decoding each code pattern that has been selected as a decoding target when a decode instruction is received after the first identification mark has been noticeably displayed; and
noticeably displaying, based on a result of the decoding, the second identification mark superimposed on the image of a code pattern that has been selected as a decoding target and has been successfully decoded.
5. The computer readable recording medium according to claim 4 , wherein the memory is configured to store a third identification mark indicating that a code pattern is not selected as a decoding target; and
wherein said functions further comprise noticeably displaying the third identification mark superimposed on the image of a code pattern that has not been selected as a decoding target.
6. The computer readable recording medium according to claim 5 , wherein the memory is configured to store a fourth identification mark indicating that a code pattern has not been successfully decoded; and
wherein said functions further comprise noticeably displaying, based on the result of the decoding, the fourth identification mark superimposed on the image of a code pattern that has been selected as a decoding target and has not been successfully decoded.
