Image reading device storing barcode types and associated designation information and image reading method

An image reading device comprising:

• storage storing therein a plurality of barcode types and designation information items, each of the designation information items being associated with any of the plurality of barcode types;
• an image reading section configured to acquire a read image by reading a document image including a barcode image;
• a receiving section configured to receive input of a designation information item among the designation information items;
• a display section configured to display one or more barcode types among the plurality of barcode types;
• and
• a controller configured to control the storage, the receiving section, and the display section, wherein
• the barcode image exhibits a barcode belonging to any of the one or more barcode types,
• the controller causes the display section to display the one or more barcode types on the basis of the designation information item received by the receiving section, the one or more barcode types being associated with the designation information item,
• the controller determines whether or not specific conditions are satisfied, and
• when determining that the specific conditions are satisfied, the controller causes the display section to display barcode types among the plurality of barcode types in descending order of the numbers of times of reading of the respective barcode types, the specific conditions being satisfied when the number of barcode images included in the document image is equal to or larger than a first threshold and the number of barcode types of barcodes exhibited by the respective barcode images included in the document image is equal to or larger than a second threshold.
