Abstract

An apparatus that comprises: a recording switch for recording a temperature of a target object; and a judging unit that measures the temperature of the target object using a sensor at intervals of a first period and judges whether a difference in temperatures measured at the intervals is within a range of a pre-set value, is provided. The apparatus further comprises: a first acquisition unit that records and/or outputs, when a switch-on of the recording switch is detected and the difference in temperatures is within the range of the pre-set value, temperature information including a first temperature that is measured using the sensor and has become valid by the switch-on of the recording switch; and a second acquisition unit that records and/or outputs, when the switch-on of the recording switch is detected and the difference in temperatures is outside the range of the pre-set value, temperature information including a second temperature that is measured using the sensor and becomes valid when the difference in temperatures falls within the range of the pre-set value after the switch-on of the recording switch is detected.

Claims

1. An apparatus comprising:

a recording switch for recording a temperature of a target object;

a judging unit that measures the temperature of the target object using a sensor at intervals of a first period and judges whether a difference in temperatures measured at the intervals is within a range of a pre-set value;

a first acquisition unit that records and/or outputs, when a switch-on of the recording switch is detected and the difference in temperatures is within the range of the pre-set value, temperature information including a first temperature that is measured using the sensor and has become valid by the switch-on of the recording switch; and

a second acquisition unit that records and/or outputs, when the switch-on of the recording switch is detected and the difference in temperatures is outside the range of the pre-set value, temperature information including a second temperature that is measured using the sensor and has become valid when the difference in temperatures falls within the range of the pre-set value after the switch-on of the recording switch is detected.

2. The apparatus according to claim 1,

wherein the first acquisition unit records and/or outputs the temperature information that includes, in addition to the first temperature, a measured time of the first temperature, and

the second acquisition unit records and/or outputs the temperature information that includes, in addition to the second temperature, a measured time of the second temperature.

3. The apparatus according to claim 1,

wherein the second acquisition unit cancels, after the switch-on of the recording switch is detected, the switch-on of the recording switch if the difference in temperatures remains outside the range of the pre-set value for a predetermined period.

4. The apparatus according to claim 1, further comprising a display,

wherein the first acquisition unit displays, when the switch-on of the recording switch is detected, the first temperature on the display as a recorded temperature, and

the second acquisition unit displays, when the switch-on of the recording switch is detected, a message showing the apparatus is awaiting temperature convergence and displays, when the second temperature is acquired, the second temperature on the display unit as a recorded temperature.

5. The apparatus according to claim 1, further comprising a communication unit that transmits, when the temperature information has been obtained, the temperature information to a host apparatus that is external and equipped with a recording medium.

6. The apparatus according to claim 5, further comprising a display and a guide unit that receives an instruction for a switch-on of the recording switch from the host apparatus via the communication unit and displays an instruction for operation of the recording switch on the display.

7. The apparatus according to claim 1, further comprising the sensor that is a rod type sensor for inserting the sensor into the target object for measuring an internal temperature of the target object.

8. A measuring system comprising:

an apparatus according to claim 5; and

a host apparatus capable of communication with the apparatus,

wherein the host apparatus includes a recording medium that is capable of recording temperature information transferred from the measuring apparatus.

9. A method of measuring temperature comprising:

measuring a target object using an apparatus with a recording switch for recording the temperature of the target object via a sensor at intervals of a first period and judging whether a difference in temperatures measured at the intervals is within a range of a pre-set value;

recording and/or outputting temperature information, by switch-on of the recording switch, including a first temperature that is measured via the sensor and has become valid by the switch-on of the recording switch, if the difference in temperatures is within the range of the pre-set value when the apparatus detects the switch-on of the recording switch; and

recording and/or outputting temperature information, by the switch-on of the recording switch and if the difference in temperatures is outside the range of the pre-set value when the apparatus detects the switch-on of the recording switch, including a second temperature that is measured via the sensor and has become valid when the difference in temperatures falls within the range of the pre-set value after the apparatus detects the switch-on of the recording switch.

10. The method according to claim 9,

wherein the step of recording and/or outputting the temperature information including the first temperature records and/or outputs the temperature information that includes, in addition to the first temperature, a measurement time of the first temperature, and

the step of recording and/or outputting the temperature information including the second temperature records and/or outputs the temperature information that includes, in addition to the second temperature, a measurement time of the second temperature.

11. The method according to claim 9,

further comprising canceling the switch-on of the recording switch by the apparatus if the difference in temperatures remains outside the range of the pre-set value for a predetermined period.

12. The method according to claim 9, wherein the apparatus includes a display,

the step of recording and/or outputting the temperature information including the first temperature includes displaying, when the apparatus detects the switch-on of the recording switch, the first temperature on the display as a recorded temperature, and

the step of recording and/or outputting the temperature information including the second temperature includes displaying, when the apparatus detects the switch-on of the recording switch, a message showing that temperature convergence is awaited on the display and displaying, when the second temperature is acquired, the second temperature on the display as a recorded temperature.
