Abstract

A heating control method of a heat development recording device includes a heating step in which after start-up of the heat development recording device, a heat development section is heated to a target temperature by a plate heater, a temperature holding step in which after the temperature of the plate heater has reached the target temperature, the target temperature is held for a prescribed time, and a step in which after the target temperature has been held for the prescribed time, the heat development section is set up in the recordable state, wherein after start-up of the heat development recording device, operation history information from the time of the last start-up is collected; and after reaching the target temperature at the time of the present start-up, a temperature holding time is determined depending upon the operation history information.

Claims (14)

1. A heating control method of a heat development recording device, comprising:

heating a heat development section to a target temperature by a heater after a start-up of the heat development recording device;

holding the target temperature for a prescribed time after the heater has reached the target temperature;

setting up the heat development section in a recordable state after the target temperature has been held for the prescribed time,

wherein operation history information from a last start-up of the heat development recording device is collected, and the prescribed time is determined based on the operation history information.

2. The heating control method according to claim 1 , wherein the prescribed time is set up in such a manner that in a case where an elapsed time from a completion of a last operation is short, the prescribed time is short and that in a case where an elapsed time from a completion of the last operation is long, the prescribed time is long.

3. The heating control method according to claim 1 , wherein the prescribed time is set up according to a temperature holding time set up at the last time.

4. The heating control method according to claim 1 , wherein the prescribed time is set up depending on whether or not the temperature holding time has elapsed after reaching the target temperature at a time of the last start-up.

5. A heat development recording device in which a heat development section is heated to a target temperature by a heater after a start-up of the heat development recording device; the target temperature is held for a prescribed time after the heater has reached the target temperature; and the heat development section is set up in a recordable state after the target temperature has been held for the prescribed time, the heat development recording device comprising:

a temperature sensor for detecting at least a temperature of the heater,

a history information storage section for storing a start-up and stop information of the heat development recording device and a detected value of the temperature sensor along with an elapsed time as operation history information, and

a control section for computing the prescribed time depending on the operation history information stored in the history information storage section.

6. The heat development recording device according to claim 5 , comprising a press roll for pressing a heat development recording material to the heater of the heat development section, wherein the press roll is rotation driven during start-up of the heat development recording device.

7. The heat development recording device according to claim 6 , wherein the press roll is intermittently driven.
