First Claim
Patent Images
1. A measuring instrument comprising:
- a plurality of sensors each of which includes an analyte applying portion, a reacting portion, and a base end provided with a sensor terminal;
a sensor cartridge including a cartridge body and a sealing member for accommodating the plurality of sensors;
a pusher movable vertically and back and forth for pushing one of the plurality of sensors; and
an arithmetic circuit including a circuit terminal for performing computation based on a current generated at the reacting portion;
the cartridge body including an upper surface, a front surface connected thereto, and a plurality of sensor retaining grooves, each of the sensor retaining grooves including a first opening formed at the upper surface and a second opening formed at the front surface for communication with the first opening, the sealing member closing the first opening and the second opening with the sensor loaded in the sensor retaining groove;
the sensor retaining groove including a sensor accommodating portion for accommodating the sensor, and a pusher receiving portion for receiving the pusher, the sensor accommodating portion communicating with the first opening and the second opening, the pusher receiving portion communicating with the first opening while being connected to the sensor receiving portion at a location opposite to the second opening;
the sensor being accommodated in the sensor accommodating portion so that the analyte applying portion faces the second opening;
the circuit terminal being so provided as to contact the sensor terminal of the sensor when the analyte applying portion is pushed by the pusher for exposure to the outside of the instrument.

Abstract
A sensor cartridge (1) for use on a sensor feeder includes a cartridge body (10) and a mold (12). The cartridge body (10) has an upper surface (10a), a front (10c) extending continuously from the upper surface, and a plurality of sensor-holding slots (11). Each of the sensor-holding slots (11) includes a first opening formed in the upper surface (10a) and a second opening formed in the front (10c) and communicating with the first opening. The mold (12) closes the first opening and second openings in case sensors are charged in the sensor-holding slots (11).
