Abstract
Abstract An electronic thermometer in which a probe having a temperature sensor element disposed at a tip end portion and a planar terminal portion formed at a base end portion is employed for electronically measuring and displaying temperature on the basis of the characteristic of the temperature sensor element. The apparatus comprises a pair of members pivotally hinged together at one ends thereof so as to be selectively opened and closed about the hinged portion, and probe sandwiching means provided at the other ends of the members opposite to the hinged end for holding the terminal portion of the probe between the members in a sandwiched manner. The sandwiching means is provided with means for forming electric connection between the terminal portion and a temperature measuring and displaying circuit incorporated in the member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
139 words
An electronic thermometer for receiving a temperature probe having a temperature sensing means and a terminal portion, comprising: (a) means for holding the probe including a pair of probe holding members hingedly connected for pivotal movement from an open position to a closed position, whereby the probe is held between said two probe holding members; (b) a temperature measuring circuit on said holding means; (c) means for electrically connecting the terminal portion of the probe to said temperature sensing means and to the temperature measuring circuit; (d) probe switch means on said holding means; (e) means for operating said probe switch means only when the probe is held between said members in a predetermined manner; (f) means for displaying the temperature measured; and (g) control means for initiating said temperature measuring circuit upon the actuation of said switching means.
Claim 2
Dependent Claim
139 words
An electronic thermometer for receiving a temperature probe having a temperature sensing means and a terminal portion, comprising: (a) means for holding the probe including a pair of probe holding members hingedly connected for pivotal movement from an open position to a closed position, whereby the probe is held between said two probe holding members; (b) a temperature measuring circuit on said holding means; (c) means for electrically connecting the terminal portion of the probe to said temperature sensing means and to the temperature measuring circuit; (d) probe switch means on said holding means; (e) means for operating said probe switch means only when the probe is held between said members in a predetermined manner; (f) means for displaying the temperature measured; and (g) control means for initiating said temperature measuring circuit upon the actuation of said switching means.
Claim 3
Dependent Claim
27 words
The electronic thermometer of claim 1 including an actuator for said switching means, said actuator actuating said switching means when a probe is inserted between said members.
Claim 4
Dependent Claim
30 words
The electronic thermometer of claim 2 wherein said members include aligned openings and a portion of said actuator extending through said openings when there is no probe between said members.
Claim 5
Dependent Claim
45 words
The electronic thermometer of claim 3 wherein said actuator cannot extend through said opening when a probe is inserted between said members, and wherein the terminal portion of the probe exerts a force on the actuator forcing said actuator in contact with said switching means.
Claim 6
Dependent Claim
23 words
The electronic thermometer of claim 1 wherein said control means includes a power supply source, said temperature measuring circuit, and said displaying means.
Claim 7
Dependent Claim
34 words
The electronic thermometer of claim 5 including a manual on/off switch and a timer circuit electrically independent of said on/off switch wherein a time display is displayed in response to closing said on/off switch.
Claim 8
Dependent Claim
153 words
An electronic thermometer comprising: (a) a probe having a temperature sensing element disposed at one end thereof and a generally planar terminal portion formed at another end thereof; (b) means for holding said probe including a pair of probe holding members hingedly connected for pivotal movement from an open position to a closed position, whereby said probe is held between said members; (c) a pair of cooperating electrode means on said probe and on said holding means; (d) temperature measuring means on said holding means, and said electrode means on said holding means being connected to said temperature measuring means; (e) probe switch means on said holding means; (f) means for cooperating said probe switch means only when the probe is held between said members in a predetermined manner; (g) means for displaying the temperature measured; and (h) control means for initiating said temperature measuring circuit upon the actuation of said switching means.
Claim 9
Dependent Claim
153 words
An electronic thermometer comprising: (a) a probe having a temperature sensing element disposed at one end thereof and a generally planar terminal portion formed at another end thereof; (b) means for holding said probe including a pair of probe holding members hingedly connected for pivotal movement from an open position to a closed position, whereby said probe is held between said members; (c) a pair of cooperating electrode means on said probe and on said holding means; (d) temperature measuring means on said holding means, and said electrode means on said holding means being connected to said temperature measuring means; (e) probe switch means on said holding means; (f) means for cooperating said probe switch means only when the probe is held between said members in a predetermined manner; (g) means for displaying the temperature measured; and (h) control means for initiating said temperature measuring circuit upon the actuation of said switching means.
Claim 10
Dependent Claim
26 words
The electronic thermometer of claim 7 including actuator for said switching means, said actuator actuating said switching means when a probe is inserted between said members.
Claim 11
Dependent Claim
30 words
The electronic thermometer of claim 8 wherein said members include aligned openings and a portion of said actuator extending through said openings when there is no probe between said members.
Claim 12
Dependent Claim
45 words
The electronic thermometer of claim 9 wherein said actuator cannot extend through said opening when a probe is inserted between said members, and wherein the terminal portion of the probe exerts a force on the actuator forcing said actuator in contact with said switching means.
Claim 13
Dependent Claim
23 words
The electronic thermometer of claim 7 wherein said control means incudes a power supply source, said temperature measuring circuit, and said displaying means.
Claim 14
Dependent Claim
