An object of the present invention is to accurately control temperatures of microorganisms or the like. In the present invention, a temperature controller comprises a plurality of cells for storing microorganisms or the like, heaters, and a cooling section. The heaters selectively heat the plurality of cells, and the cooling section wholly cools the plurality of cells. When the maximum value of temperature of a plurality of places is not lower than a first lower limit, the cooling section is driven. When a temperature of one place is not higher than a first lower limit, the heater to heat the place is driven. When the maximum value is not higher than a second lower limit, the cooling section is stopped. When a temperature of one place is not lower than a second upper limit, the heater to heat the place is not driven.

What is claimed is: 1. A temperature controlling method, to control a temperature controller comprising: a temperature-controlled object whose temperature is to be controlled; heaters for heating a plurality of places of said temperature-controlled object; and a cooling section for cooling the whole of said temperature-controlled object, the method executing: (a) a step of measuring temperatures of said plurality of places; (b) a step of driving said cooling section when at least one of said temperatures of said places is not lower than a first upper limit; (c) a step of selectively driving one of said heaters for heating one of said places when said temperature of the one of said places is not higher than a first lower limit; (d) a step of not driving said cooling section when all of said temperatures of said places are not higher than a second lower limit; and (e) a step of not driving one of said heaters for heating one of said places when said temperature of the one of said places is not lower than a second upper limit. 2. The temperature controlling method according to claim 1, wherein said second lower limit is lower than said first upper limit, and is a value obtained by adding a third positive value to a target value of a temperature of said temperature-controlled object, and said second upper limit is higher than said first lower limit, and is a value obtained by adding a fourth positive value to said target value. 3. The temperature controlling method according to claim 2, further executing: (f) a step of calibrating to update said target value to a new target value according to an atmospheric temperature of said temperature controller when at least one of said temperatures of said places is higher than said second lower limit, all of said temperatures of said places are lower than said first upper limit, and any of said temperatures of said places is higher than said first lower limit and lower than said second upper limit, and again executing said steps (b) and (c) by using said target value updated in said step (f). 4. The temperature controlling method according to claim 3, again executing said steps (d) and (e) by using said target value updated in said step (f). 5. The temperature controlling method according to claim 1, wherein said temperature-controlled object has a plurality of containers capable of housing cultures. 6. The temperature controlling method according to claim 5, wherein said first upper limit is a value obtained by adding a first positive value to a target value of a temperature of said temperature-controlled object, and said first lower limit is a value obtained by subtracting a second positive value from said target value. 7. The temperature controlling method according to claim 1, wherein said first upper limit is a value obtained by adding a first positive value to a target value of a temperature of said temperature-controlled object, and said first lower limit is a value obtained by subtracting a second positive value from said target value. 8. A temperature controller, comprising: a housing section for housing a plurality of containers whose temperatures are to be controlled; a cooling section for concurrently cooling all of said plurality containers housed in said housing section; a plurality of heaters for selectively heating said plurality of containers; a plurality of sensors for measuring temperatures of respective places heated by said plurality of heaters; and a control section for controlling a drive of said cooling section on the basis of a target value of temperatures of said containers and on the basis of results of temperature measurement by said plurality of sensors, and for controlling a drive of said heaters on the basis of each said result of temperature measurement by said sensors such that said cooling section is driven when at least one of said temperatures of said places is not lower than a first upper limit, one of said heaters is selectively driven to heat one of said places when said temperature of the one of said places is not higher than a first lower limit, said cooling section is not driven when all of said temperatures of said places are not higher than a second lower limit, and one of said heaters is not driven when said temperature of one of said places is not lower than a second upper limit. 9. The temperature controller according to claim 8, further comprising: a sensor for measuring an atmospheric temperature; and a calculating section for updating said target value on the basis of said atmospheric temperature and said target value. 10. The temperature controller according to claim 8, further comprising: a sensor for measuring an atmospheric temperature; and a storage section for storing calibration data that provides a calibration value on the basis of said atmospheric temperature and said target value, wherein said control section updates said target value with said calibration value on the basis of said calibration data, said atmospheric temperature and said target value.
