INFORMATION READING APPARATUS AND INFORMATION READING METHOD
First Claim
1. A portable information reading apparatus adapted to read information recorded on a non-contact type IC chip, the information reading apparatus comprising:
- a first antenna which has a loop-like or spiral-like shape and is provided in a plate-like manner on one surface of an outer shape;
a second antenna which is provided in a plate-like manner on a side face with respect to the one surface, has a loop-like or spiral-like shape, and has a size in a short axis of the second antenna which is smaller than a size in a short axis of the first antenna; and
a control part adapted to communicate with the non-contact type IC chip by selectively using one of the first antenna and the second antenna and obtain the information recorded on the non-contact type IC chip,wherein in a case where the information is obtained from the non-contact type IC chip via the second antenna, the control part determines whether or not the information obtained via the second antenna corresponds to a search condition used for searching for the information recorded on the non-contact type IC chip.

Abstract
A portable information reading apparatus includes: a first antenna which has a loop or spiral like shape and is provided in a plate-like manner on one surface of an outer shape; a second antenna which is provided in a plate-like manner on a side face of the one surface, has a loop or spiral like shape, and has a smaller size in a short axis than that in a short axis of the first antenna; and a control part adapted to communicate with a non-contact type IC chip by using the first or second antenna and obtain the information recorded on the IC chip, in which when the information is obtained from the IC chip via the second antenna, the control part determines whether the information obtained via the second antenna is a search condition for searching for the information recorded on the IC chip.

19. An information reading method of reading information recorded on a non-contact type IC chip by using a portable information reading apparatus including a control part, the information reading method comprising the steps of:
-
allowing the control part to select one of a loop-like or spiral-like shape first antenna and a second antenna which has a loop-like or spiral-like shape and has a smaller size in a short axis than a size in a short axis of the first antenna to communicate with the non-contact type IC chip via the selected antenna and obtain the information recorded on the non-contact type IC chip; and allowing the control part to determine, in a case where the information is obtained from the non-contact type IC chip via the second antenna, whether or not the information obtained via the second antenna corresponds to a search condition used for searching for the information recorded on the non-contact type IC chip.
