Each processing (developing, fixing, and stabilizing) solution is appropriately replenished from each replenishing tank 31 to 33, and each processing tank 23, 24, and 25c is appropriately replenished with water from the replenishing tank 34. ing.

  As described above, during operation of the image recording device 1 and the developing device 21, the heaters 23b and 24b are controlled based on the detected temperatures of the developing temperature sensor 23c and the fixing temperature sensor 24c in FIG. The developing temperature and the fixing temperature are controlled by adjusting the temperatures of the developing solution and the fixing solution in the fixing tank 24. At this time, as shown in FIGS. 2 to 4, the outer wall of the fixing tank 24 on the first stabilization tank 25 a side is the heat insulating member 62, and the outer wall of the developing tank 23 and the fixing tank 24 and the heat insulating member 61 are partitioned. Since each of the spaces 60 is covered and has a heat insulating structure, it is possible to prevent the liquid temperature in the developing tank 23 and the fixing tank 24 from being lowered.

  At the start of the operation, when the opening / closing member 61a below the fixing tank 24 is open as shown in FIG. 6, the motor is operated to close it.

  Further, when the above-described image recording and developing process is completed and the operation of the developing device 21 is stopped, the opening / closing member 61a below the developing tank 23 and the fixing tank 24 opens downward as shown in FIG. The air in the space 60 partitioned between the outer walls of the tank 23 and the fixing tank 24 and the heat insulating member 61 flows as indicated by arrows in FIG. Therefore, the air in the partitioned space 60 that is warmed during the operation of the apparatus flows above the developing tank 23, and the cooled air enters the partitioned space 60 from below the developing tank 23 and the fixing tank 24. The partitioned space 60 is cooled. Then, for example, when the detected temperature of the sensor 23c or 24c in FIG. 5 becomes a predetermined temperature or less, the operation of the apparatus is stopped.

  As described above, during the operation of the apparatus, the heat insulation structure as shown in FIGS. 3 and 4 can suppress the temperature drop of the developing solution in the developing tank 23 and the fixing solution in the fixing tank 24.

The temperature of the fixing solution inside can be further stabilized.

  Further, when the operation of the apparatus is stopped, as shown in FIG. 6, the inside of the partitioned space 60 is cooled by opening a part of the opening / closing members 61a of the heat insulating structure, and the inside of the developing tank 23 and the fixing tank 24. Each liquid temperature can be lowered relatively quickly.

  Next, a modification of the heat insulating structure of FIGS. 3 and 4 will be described with reference to FIG. FIG. 8 is a cross-sectional side view of an essential part schematically showing a modification of the heat insulating structure shown in FIGS. In the example of FIG. 8, an outside air temperature control mechanism is provided in a part of the partitioned space of FIGS.

  As shown in FIG. 8, a part of the lower part of the developing tank 23 and the fixing tank 24 of the heat insulating member 61 (position of the opening / closing member 61a in FIG. 6) is switched to the heating mode or the cooling mode so as to warm or cool the outside air temperature. The outside air temperature adjustment mechanism 66 that adjusts the temperature and the fan 67 that sends the temperature-controlled air toward the partitioned space 60 are provided. As shown in FIG. 7, the control unit 50 controls the outside air temperature adjustment mechanism 66 and the fan 67 based on the detected temperatures of the developing temperature sensor 23c and the fixing temperature sensor 24c.

  That is, when the operation of the developing device 21 is started and the developer in the developer tank 23 and the fixer in the fixing tank 24 are warmed by the heaters 23b and 24b in FIG. 5, the outside air temperature adjusting mechanism 66 is heated and the hot air is heated in FIG. When the developer in the developer tank 23 and the fixer in the fixing tank 24 reach the set temperature as indicated by the arrow, the outside temperature adjusting mechanism 66 is stopped and the fan 67 is also stopped. When the liquid temperature in the developing tank 23 and the fixing tank 24 falls below the set temperature, the heaters 23b and 24b in FIG. 5 are activated, and the outside air temperature adjusting mechanism 66 and the fan 67 are also activated. Such an operation is repeated during operation of the apparatus.

  Further, when the operation of the developing device 21 is stopped, the outside air temperature adjusting mechanism 66 is cooled, and the cool air flows into the space partitioned by the fan 67 as shown by the arrows in FIG. When the fixing solution in the tank 24 is cooled down to a predetermined temperature or less, the operation of the apparatus is stopped.

  As described above, during operation of the apparatus, in addition to the heat insulation structure as shown in FIGS. 3 and 4, the outside air temperature adjusting mechanism 66 and the fan 67 are provided, so that the developer in the developing tank 23 and the fixing tank 24 are fixed. The temperature of the solution can be increased rapidly, and the temperature drop of the developer in the developer tank 23 and the fixer in the fixing tank 24 can be suppressed. The heat retention effect is improved, and the stability of the developer and the fixing solution is improved. Therefore, each ON time of the heater 23b for the developing tank 23 and the heater 24b for the fixing tank 24 can be shortened, and power consumption can be reduced.

  Further, when the operation of the apparatus is stopped, the space 60 partitioned by the outside air temperature adjustment mechanism 66 and the fan 67 in the cooling mode is cooled, and each liquid temperature in the developing tank 23 and the fixing tank 24 is quickly increased. Can be reduced.

  Next, another modification of the heat insulating structure of FIGS. 3 and 4 will be described with reference to FIG. FIG. 9 is a principal part front view (a) and a principal part top view (b) schematically showing another modification of the heat insulating structure of FIG. 3 and FIG. In the example of FIG. 9, each treatment tank of FIGS. 1 and 2 is formed of a heat insulating member to form a heat insulating structure.

  As shown in FIGS. 9A and 9B, the heat insulating member 62 is disposed between the fixing tank 24 and the first stabilizing tank 25a, and the developing tank 23, the fixing tank 24, and the first to third stabilizing tanks 25a. , 25b, 25c are constituted by a heat insulating member 65.

  According to the heat insulation structure of FIGS. 9A and 9B, a heat insulation effect can be obtained by configuring each treatment tank to be surrounded by a heat insulation member, and the treatment liquid in each treatment tank 23 to 25c can be obtained. Since the temperature fluctuation is suppressed, the heat retention effect of the processing liquid in the processing tanks 23 to 25c is improved, the stability of each processing liquid is improved, the heater ON time can be shortened, and the power consumption can be reduced.

  As shown in FIG. 10, the developer replenishing tank 31, the fixer replenishing tank 32, and the stabilizer replenishing tank 33 shown in FIG. 2, the developing tank 23, the fixing tank 24, and the first to third stabilizing tanks 25a. , 25b, 25c are integrally disposed on top of each of the tanks 23 to 25c.

  As described above, by arranging the replenishing tanks 31 to 33 in the upper parts of the tanks 23 to 25c and covering the upper parts of the tanks 23 to 25c, the entire tank upper part can be formed into a heat insulating structure. For this reason, it is possible to suppress heat dissipation from the tanks 23 to 25c to the upper part, and it is possible to warm the replenishing tanks 31 to 33 with this heat. For this reason, since the temperature fluctuation of each processing liquid in each tank 23 thru | or 25c is suppressed and each processing liquid replenished to each tank 23, 24, 25c is warmed, the processing in each tank 23, 24, 25c is carried out. The heat retention effect of the liquid is improved, the stability of the processing liquid is improved, the heater ON time can be shortened, and the power consumption can be reduced.
