As shown in this figure, the display / operation unit A (24), the display / operation unit B (25), and the like are provided on the surface of the casing of the host control device 20.
4A is an enlarged view of the display / operation unit A (24), and FIG. 4B is an enlarged view of the display / operation unit B (25).
The display / operation unit A (24) is for setting and displaying the current time (hour, minute), schedule control ON time, and OFF time. As shown in FIG. There are provided four operation keys of a two-digit seven-segment display 3a, 3b and 3c, an up key 3d, a down key 3e, a selection key 3f and a confirmation key 3g. Here, as the 7-segment displays 3a to 3c, for example, LEDs, fluorescent display tubes, liquid crystal displays, and the like are used.
The display device 3a is a time display device for displaying the current time and the schedule time “hour”, and “00” to “23” are displayed. During operation, the current hour is usually displayed.
The display device 3b is a minute display device that displays 'minute' of the current time and the schedule time, and “00” to “59” are displayed. During operation, the current minute is usually displayed.
The display 3c is a mode setting display that displays various setting modes. The mode setting display 3c displays “on” in the mode for setting the on time, and “oF” in the mode for setting the off time. It is normally off during operation.
The selection key 3f is an operation key for sequentially selecting the mode setting display 3c, the hour display 3a, and the minute display 3b.
The up key 3d and the down key 3e are the contents of the indicators 3a to 3c selected by the selection key 3f (for example, “00” to “23” when the selected indicator is 3a, “ In the case of “00” to “59” and 3c, the operation keys are used to select “on” or “oF”). The content displayed on the display 3a or 3b increases by one every time the up key 3d is operated, and decreases by one every time the down key 3e is operated.
The confirmation key 3g is an operation key for confirming the on time and off time of the schedule control selected by operating the selection key 3f, the up key 3d, and the down key 3e.

Next, the display / operation unit B (25) shown in FIG. 4B will be described.
As shown in this figure, a display / operation unit B (25) for performing setting and execution of schedule control and stop has an all-on key 3h for immediately lighting all lights of the showcase, There are provided a full turn-off key 3i for turning off all the case lights immediately, a turn-on key 3j for turning on canopy lights (work lights), and a schedule key 3k for setting schedule control.
Further, there are provided a display 3l indicating the state of full lighting / non-lighting, a display 3m indicating the lighting state of the canopy, and indicators 3n, 3o and 3p for indicating the schedule control state of lighting. Here, the indicator 3n is a one-day stop indicator that displays that the schedule control ON control is set to stop for one day, and the indicator 3o can stop the schedule control ON control for two days. A two-day stop indicator that displays that the current state is set, and 3p is a stop indicator that indicates that the continuous stop of the on-control of the schedule control is set. For example, LEDs are used as these indicators.

The schedule key 3k is an operation key for selecting and setting the states of normal schedule control, schedule control on-control one day stop, schedule control on-control two-day stop, and schedule control stop.
As will be described in detail later, when the schedule key 3k is pressed once, the indicator 3n for the one-day stop is turned on, and the next control (for the next day) of the schedule control is prohibited. When the key 3k is pressed once more (two times in total), the one-day stop indicator 3n is turned off, the two-day stop indicator 3o is turned on, and the on-control is continuously performed twice (next day and day after day). Min) Set to be prohibited. When the key 3k is pressed once more (three times in total), the 2-day stop indicator 3o is turned off, the stop indicator 3p is turned on, and the schedule control is set to a stop state. When the key 3k is pressed once more (four times in total), all the indicators (3n, 3o, 3p) are turned off, and normal schedule control based on the schedule time stored in the storage unit 23 is performed.
Thus, in the present invention, the lighting states of the indicators 3n to 3p are controlled according to the operation of the schedule key 3k and the passage of time, and the stop and execution of the schedule control are controlled based on the lighting state. Further, the operator can check the schedule control state by observing the lighting state.
In addition to prohibiting on control of schedule control as described above, schedule control based on a special schedule time set separately from the normal schedule may be executed. For example, this is effective when it is desired to change the schedule time to a special schedule time due to a special event or the like.

(Clock setting)
A method of setting the current time using the display / operation unit A (24) will be described.
When the time has never been set in the clock management unit 26 in FIG. 2, the hour indicator 3a blinks “00”. By selecting the current time “00” to “23” (hours) with the selection key 3f, up key 3d, and down key 3e and pressing the enter key 3g, the hour indicator 3a is continuously displayed, and then the minute The display 3b blinks “00”.
Subsequently, by selecting the current time “00” to “59” (minutes) with the selection key 3f, the up key 3d, and the down key 3e and pressing the enter key 3g, the minute indicator 3b is continuously displayed. The set time (hour, minute) is stored in the clock management unit 26. The clock management unit 26 is provided with a calendar timer and the like, and the time is counted even during a power failure by a battery or the like.
When time correction is necessary, for example, “08” may be assigned to the mode setting display 3c to set the time correction mode. The time setting method may be the same method as described above. Further, when the indicators 3a and 3b are displaying the time, the dot 3t of any of the indicators 3a and 3b may blink.

(Schedule time setting)
Next, a method for setting the schedule time, that is, the lighting time (ON time) and the lighting time (OFF time) of the illumination will be described.
In the display / operation unit A (24), when the mode setting display 3c is selected by pressing the selection key 3f, “on” is displayed blinking on the mode setting display 3c and the time display is displayed. The set ON time is displayed on the indicator 3a and the minute indicator 3b. When the ON time data is not yet input, for example, only “.” (Dot 3t) of the hour display 3a and the minute display 3b is displayed.
When “on” is blinking and displayed on the mode setting display 3c, the mode setting display 3c displays “on” or “oF” by pressing the up key 3d or the down key 3e. You can choose.
When “on” or “oF” is blinking on the mode setting display 3c, the “on” or “oF” display is continuously lit by pressing the enter key 3g, and the mode is determined. Is done. When “on” is selected, the on-time setting mode is selected, and when “oF” is selected, the off-time setting mode is selected.
Here, when the mode is determined, the hour indicator 3a starts blinking. In this state, pressing the up key 3d or the down key 3e selects the hour ("0" to "23"), and pressing the confirm key 3g confirms the time (hour) of the mode. The indicator 3a is continuously lit, and then the minute indicator 3b flashes. The minutes ("0" to "59") are selected by pressing the up key 3d or the down key 3e in the same procedure as the time display 3a, and the schedule of the mode is pressed by pressing the confirmation key 3g. The time is fixed and stored in the storage unit 23.
In the same manner, the schedule time of the other mode (“on” or “oF”) can be determined.

Further, when setting the special schedule time described above, the schedule key 3k in the display / operation unit B (25) is pressed once or twice to display the one-day stop indicator 3n or two-day stop. After the display 3o is turned on, within a predetermined time (for example, 5 seconds), “on” or “oF” is selected by the up key 3d or the down key 3e in the same manner as described above, and the schedule time setting operation is performed. Can start. A special schedule time (special program 1) that is executed in place of the schedule that is stopped in response to the schedule time setting operation that is performed when the indicator 3n that is stopped every day is turned on. A special schedule time (special program 2) that is executed in place of the schedule that is stopped in response to the schedule time setting operation that is performed when the indicator 3o that is stopped for two days is lit. Is done. The set special schedule time is stored in the storage unit 23 separately from the normal schedule time.
When the time and schedule on / off time are input halfway and left for a predetermined time (for example, 10 seconds), the key input data input halfway is discarded.

FIG. 5 is a diagram illustrating a state in which the schedule time is stored in the schedule time storage unit of the storage unit 23.
In the example shown in Fig. 5 (a), in addition to the normal schedule (on time is 10:00, off time is 22:00), the on time is 9:30 and the off time is 1:30 the next day. A case where a special program 1 is set and a special program 2 is not set is shown. When not set, a code (-:-) indicating a null value (null) is written.
FIG. 5B shows a case where a special program 2 having an on time of 9:30 and an off time of 21:30 is set in addition to the same normal schedule and special program 1 as described above. ing.
Thus, the schedule time storage unit provided in the storage unit 23 is provided with an area for storing the normal schedule, the special program 1 and the special program 2, and is set by the above-described schedule time setting operation. Each scheduled time (program) is stored in a corresponding area.
The determination unit 27, which is a schedule control means, compares the current time of the clock management unit 26 with the on time and off time of the schedule stored in the schedule time storage unit of the storage unit 23, and the on time is reached. Sometimes, an illumination-on command is transmitted to each electronic controller 1 via the communication unit 21, and an illumination-off command is transmitted to each electronic controller 1 when the off time is reached. Each electronic controller 1 performs lighting on / off control of the connected showcase 2 in accordance with the on command or the off command from the host control device 20.

Next, processing relating to schedule control executed by the determination unit 27 will be described with reference to the flowcharts of FIGS. 6 is a schedule control main process, FIG. 7 is a time pattern registration process, FIG. 8 is a schedule state change process, FIG. 9 is a special program input process, FIG. 10 is an off output process, and FIG. 11 is an off output process. 1, FIG. 12 shows off output processing 2, FIG. 13 shows off output processing 3, FIG. 14 shows off output processing 4, and FIG. 15 shows on output processing.
FIG. 6 is a flowchart of the schedule control main process. As shown in the figure, in the schedule control main process, a schedule time registration process (S100), a schedule state change process (S200), an off output process (S300), and an on output process (S400) are sequentially executed. This schedule control main process is performed when the operation keys (3d, 3e, 3f, 3g, and 3k) of the display / operation unit A (24) and the display / operation unit B (25) are operated, It is executed every hour (for example, every minute).

  FIG. 7 is a flowchart of time pattern registration processing (S100) for setting a normal schedule. In this process, the setting of the normal schedule lighting / extinguishing time (on time / off time) is changed by operating the operation keys 3d, 3e, 3f and 3g of the display / operation unit A (24) as described above. (Step S101) is a process of storing the changed normal schedule ON time or OFF time in the normal schedule area in the schedule time storage unit of the storage unit 23 (step S102).

FIG. 8 is a flowchart showing the flow of the schedule state change process (S200).
In this process, it is first determined whether or not the schedule key 3k of the display / operation unit B (25) has been pressed (S201). If not, the process ends.
When the schedule key 3k is pressed, it is determined whether all the indicators 3n to 3p of the display / operation unit B (25) are turned off (S202). The display 3n is turned on (continuous lighting) (S203). Then, a special program input process (S204) is executed. Although details will be described later, this processing is processing for setting a special program 1 in accordance with the operation of the display / operation unit A (24).
Next, it is determined whether or not the on time and off time of the special program 1 are set (S205). When the on time and off time of the special program 1 are set, the current time is set to the normal time. It is determined whether or not it is between the off time of the schedule and the on time of the special program 1 (S206). If YES, the daily stop display 3n is blinked (S208), and if NO, it remains as it is. This schedule state change process is terminated.
On the other hand, when the special program 1 is not set, it is determined whether or not the current time is between the normal schedule off time and the on time (S207), and the current time is normal schedule off. When the time is between the on-time and the on-time, the lit one-day stop indicator 3n is set in a blinking state (S208). Otherwise, the schedule state changing process is terminated.

If all the indicators 3n to 3p are not turned off as a result of the determination in step S202, it is determined whether or not the indicator 3n stopped for one day is lit or blinking (S209). As a result, when the one-day stop indicator 3n is lit or blinking, the two-day stop indicator 3o is turned on (continuous lighting), and the one-day stop indicator 3n is turned off (S210). Then, the process proceeds to the special program input process (S211). Although details will be described later, this processing is processing for setting the on time and off time of the special program 2 in accordance with the operation of the display / operation unit A (24).
Next, it is determined whether or not the on time and off time of the special program 2 are set in the storage unit 23 (S212). When the special program 2 is set, it is determined whether or not the current time is between the normal schedule OFF time and the special program 2 ON time. Is in a blinking state (S215). If NO, the schedule state changing process is terminated.
On the other hand, when the special program 2 is not set, it is determined whether or not the current time is between the off time and the on time of the normal schedule. As the state (S215), if it is NO, the schedule state change process is terminated as it is.

If the result of determination in step S209 is that the one-day stop indicator 3n is not lit or blinking, it is determined whether or not the two-day stop indicator 3o is lit or blinking (S216).
When the 2-day stop indicator 3o is lit or blinking (YES in S216), the on time and off time of the special programs 1 and 2 stored in the storage unit 23 are cleared, that is, null. Is written (S217). Then, the stop display 3p is turned on, and the 2-day stop display 3o is turned off (S218). When the display 3p is turned on, the 1-day stop, the 2-day stop, and the special program are cleared, and the schedule control is completely stopped.
Then, it is determined whether or not the current time is between the off time and the on time of the normal schedule (S219). If the current time is between the off time and the on time, the stop display 3p is set in a blinking state (S220). Otherwise, the schedule state changing process is terminated as it is.
On the other hand, when the indicator 3o stopped for two days is not lit or blinking (NO in S216), that is, when only the indicator 3p that is stopped is lit or blinking, all the indicators 3n to 3p are turned off ( S221). When all the indicators 3n to 3p are turned off, normal schedule control is executed. And this schedule state change process is complete | finished.

FIG. 9 is a flowchart showing the flow of the special program input process executed in steps S204 and S211.
In this process, first, it is determined whether or not the one-day stop indicator 3n is lit (S230). If not, it is determined whether or not the two-day stop indicator 3o is lit. (S231). Then, when neither the 1-day display 3n nor the 2-day display 3o is lit, this process is terminated.
When the indicator 3n that is stopped for one day is lit (YES at S230), the above-described schedule time setting operation is performed by the display / operation unit A (24) within a predetermined time (for example, 5 seconds). (S235, S237), and when a schedule time setting operation is performed, a special program of the schedule time storage unit of the storage unit 23 indicates the on time and the off time input by the operation. 1 is stored in the storage area of ON time and OFF time (S236). On the other hand, when the predetermined time (5 seconds) has passed without the schedule time setting operation being performed (YES in S237), the input processing of this special program is terminated as it is.
Further, when the one-day stop indicator 3n is turned off and the two-day stop indicator 3o is turned on (S231 is YES), within the predetermined time (for example, 5 seconds) as described above. It is determined whether or not the above-described schedule time setting operation has been performed by the display / operation unit A (24) (S232, S234). If the schedule time setting operation has been performed, the operation is input by the operation. The ON time and OFF time are stored in the storage area for the ON time and OFF time of the special program 2 in the schedule time storage unit of the storage unit 23 (S233). On the other hand, when the predetermined time (5 seconds) has passed without the schedule time setting operation being performed (YES in S234), the input processing of this special program is terminated as it is.

  As described above, in the schedule state change process S200, the process of sequentially controlling the lighting states of the indicators 3n, 3o, and 3p and the input process of the special programs 1 and 2 are performed in response to pressing of the schedule key 3k. Every time the schedule key 3k is pressed, all the indicators 3n, 3o and 3p are turned off → only the one-day stop indicator 3n is lit → only the two-day stop indicator 3o is lit → only the stop indicator 3p is lit → The states sequentially change in the order in which the indicators 3n, 3o, and 3p are all turned off. The indicators 3n and 3o are continuously lit when the timing when the schedule key 3k is pressed is when the illumination is on, and are blinked when the illumination is off. As a result, the lighting is currently lit but the next on-control is prohibited (in the case of continuous lighting), and the lighting is currently off and the next on-control is prohibited or controlled by a special program. (When blinking) can be distinguished and displayed. Similarly, the display 3p is continuously lit when the timing when the schedule key 3k is pressed is when the illumination is turned on, and blinks when the illumination is off. As a result, although the lighting is currently turned on, it is possible to distinguish and display that the next on-control is prohibited from the next time and that the lighting is currently turned off and the next on-control is prohibited. it can.

  FIG. 10 is a flowchart showing a process flow of the off-output process (S300). As shown in this figure, the off output process is a process of transmitting an off command for instructing the electronic controller 1 to turn off the illumination, but the off output process corresponding to the schedule control one day stop or the special program 1 1 (S310), off output processing 2 (S330) corresponding to schedule control 2 day stop or special program 2, off output processing 3 (S350) corresponding to normal schedule control, and off corresponding to schedule stop processing It consists of four processes of output process 4 (S370).

FIG. 11 is a flowchart of the off-output process 1 corresponding to the schedule control one day stop or special program 1.
In this process, first, it is determined whether or not the one day stop indicator 3n is flashing (S311), and if it is not flashing, it is determined whether or not it is lit (continuous lighting) (S312). . As a result, the off-output process 1 is ended when the indicator 3n that is stopped for one day is neither flashing nor lit. Even if the indicator 3n that is stopped for one day is lit, if the current time is not the normal schedule off time (NO in S313), the off output processing 1 is terminated. When the daily stop indicator 3n is lit and the current time coincides with the normal schedule off time (YES in S313), the lit daily stop indicator 3n is changed to a blinking state. (S314), a command to turn off the illumination of the showcase case 2 (off command) is transmitted to the electronic controller 1 (S315), and the off output processing 1 is terminated.

When the one day stop indicator 3n is blinking (YES in S311), it is determined whether or not the special program 1 on time and off time are stored in the schedule time storage unit of the storage unit 23. (S316). As a result, when the on time and off time of the special program 1 are set, it is determined whether or not the current time is not the off time of the special program 1 (S317). Process 1 is terminated. On the other hand, when the current time coincides with the off time of the special program 1 (S317 is NO), the off time of the special program 1 stored in the schedule time storage unit of the storage unit 23 is cleared ( (S318). Then, the indicator 3n that is stopped for one day is turned off (S319), and an off command is transmitted to the electronic controller 1 (S320).
When the special program 1 on / off time is not set and the determination result in step S316 is NO, it is determined whether or not the current time is not the normal schedule off time (S321). When it is not time, this off output processing 1 is ended. On the other hand, when the current time coincides with the normal schedule off time (NO in S321), the one-day stop display 3n is turned off (S319), and an off command is transmitted to the electronic controller 1 (S320). The off output process 1 is terminated.

  As described above, in the off-output process 1, when the one-day stop indicator 3n is in the lighting state, it is changed to the blinking state when the off time of the normal schedule is reached. If the special program 1 is not set when the indicator 3n is blinking, an off command is transmitted to the electronic controller 1 according to the normal schedule off time, and the special program 1 is set. In some cases, processing for transmitting an off command to the electronic controller 1 is performed in accordance with the off time of the special program 1.

FIG. 12 is a flowchart of the off-output process 2 (S330) corresponding to the schedule control 2-day stop or the special program 2.
In this process, it is determined whether or not the indicator 3o stopped for two days is flashing (S331), and if it is not flashing, it is determined whether or not it is continuously lit (S332). When the display 3o is not blinking or lit, and when the display 3o is lit but the current time is not the off time of the normal schedule (S333 is NO), the off output processing 2 is terminated. When the display 3o is lit and the current time is the normal schedule off time (S333 is YES), the 2-day stop display 3o is changed to a blinking state (S334), and the electronic controller 1 is turned on. An off command is transmitted (S335), and this off output process 2 is terminated.
On the other hand, when the two-day indicator 3o is blinking (YES in S331), it is determined whether or not the special program 2 on time and off time are stored in the schedule time storage unit of the storage unit 23. (S336). As a result, when the special program 2 is set, it is determined whether or not the current time coincides with the off time of the special program 2 (S337). 2 is finished. When the current time is the off time of the special program 2, the off time of the special program 2 is cleared (S338), the 2-day stop indicator 3o is turned off (S339), and the electronic controller 1 is turned off. Is transmitted (S340), the indicator 3n stopped for one day is blinked (S341), and this off output processing 2 is completed.
When the special program 2 is not set (S336: NO), it is determined whether the current time does not coincide with the normal schedule off time. If it is not the off time, the off time remains unchanged. In some cases, the display 3o is turned off, an off command is transmitted to the electronic controller 1, the display 3n is blinked (S339 to S341), and this off output processing 2 is terminated.

  As described above, in the off-output process 2, when the indicator 3o stopped for two days is in a lighting state, an off command is transmitted to the electronic controller 1 at the normal schedule off time, and two days The stop indicator 3o is changed to a blinking state. In addition, when the 2 day stop indicator 3o is flashing, when the special program 2 is set, the off time is reached, and when the special program 2 is not set, the normal schedule is set. When the off time is reached, an off command is transmitted to the electronic controller 1, and the 2-day stop display 3o is turned off and the 1-day stop display 3n is blinked.

FIG. 13 is a flowchart of the off-output process 3 corresponding to a normal schedule.
In this process, first, it is determined whether or not all of the one-day stop indicator 3n, the two-day stop indicator 3o, and the stop indicator 3p are turned off (S351). When the display devices 3n to 3p are not in the normal schedule control state in which all the indicators are turned off, this processing is terminated. Even when all of the indicators 3n to 3p are turned off, when the current time does not coincide with the off time of the normal schedule (S352 is NO), this process is terminated.
When all the indicators 3n to 3p are turned off and the current time matches the off time of the normal schedule (S352 is YES), an off command is transmitted to the electronic controller 1 (S353), and this off output processing 3 Exit.
As described above, in the off output process 3, during the normal schedule control in which all the indicators 3n to 3p are turned off, a process of transmitting an off command to the electronic controller 1 at the normal schedule off time is performed.

FIG. 14 is a flowchart of the off output process 4 corresponding to the schedule stop process.
In this process, first, it is determined whether or not the stopped display 3p is blinking (S371).
When the stop indicator 3p is blinking, it is determined whether or not the current time is not coincident with the normal schedule off time (S372), and when it is coincident, the electronic controller 1 is instructed to be off. Is transmitted (S373). If they do not match, the off-output process 4 is terminated.
On the other hand, when the stop indicator 3p is not blinking, it is determined whether or not the stop indicator 3p is lit (continuous lighting) (S374). When the result is NO, the off output process 4 is terminated.
When the stop indicator 3p is lit (YES at S374), it is determined whether or not the current time is coincident with the normal schedule off time. The off output process 4 is terminated.
When the current time is the normal schedule off time (YES in S375), the stop display 3p is set in a blinking state (S376), and then an off command is transmitted to the electronic controller 1 (S373). The off output process 4 is terminated.
As described above, in the off-output process 4, when the normal schedule off time is reached, when the stopped display 3p is in the lighting state, the display 3p is changed to a blinking state, and the electronic controller The process of transmitting an OFF command to 1 is performed.

  As described above, in the off-output process (S300), the special programs 1 and 2 are selected according to the lighting and blinking states of the one-day stop indicator 3n, the two-day stop indicator 3o, and the stop indicator 3p. Depending on whether or not is set, when the normal schedule or the special program 1 or 2 is turned off, the electronic controller 1 changes the lighting / flashing state of the indicators 3n and 3o. A process for turning off the illumination of the showcase by transmitting an off command to the camera is performed.

FIG. 15 is a flowchart showing the process flow of the on-output process (S400).
In this process, first, it is determined whether or not all the indicators 3n to 3p are turned off (S401). As a result, when all are turned off (when in the normal schedule control state), it is determined whether or not the current time matches the on time of the normal schedule (S402). An ON command is transmitted to the controller 1 to turn on the illumination of the showcase (S403), and this ON output process is terminated.
If all the indicators 3n to 3p are not turned off (NO in S401), it is determined whether or not the indicator 3n stopped for one day is blinking (S404). When the daily stop indicator 3n is blinking, it is determined whether or not the current time coincides with the on time of the special program 1 (S405). If the special program 1 is not set or if the current time does not coincide with the ON time even if the special program 1 is set (NO in S405), the ON output process is terminated. When the special program 1 is set and the current time matches the ON time (YES in S405), the ON time of the special program 1 is cleared, that is, rewritten to null (S406), and the electronic controller 1 The ON command is transmitted to the terminal (S407), and the ON output process is terminated.

When the one-day display 3n is not blinking (NO in S404), it is determined whether or not the two-day display 3o is blinking (S408). When the two-day display 3o is blinking, it is determined whether or not the current time matches the on time of the special program 2 (S409). When the special program 2 is not set, or even if the special program 2 is set, if the current time does not coincide with the ON time (NO in S409), the ON output process is terminated as it is. To do. On the other hand, when the special program 2 is set and the current time matches the on-time (YES in S409), the on-time of the special program 2 is cleared (S410), and an on command is sent to the electronic controller 1. This is transmitted (S407), and this on-output process is terminated.
As described above, when the one-day stop indicator 3n or the two-day stop indicator 3o is blinking, the ON command is not transmitted even when the normal schedule ON time is reached. If a special program 1 is set when the 1-day stop indicator 3n is flashing, an on-command is transmitted at the ON time, and a 2-day stop indicator 3o is flashing specially. If the correct program 2 is set, the ON command is transmitted at the ON time.

As described above, in the present invention, normal schedule control is performed when all of the indicators 3n to 3p are turned off, and one day stop is performed according to the number of times the schedule key 3k is pressed. By sequentially changing the lighting / flashing state of the display 3n and the display 3o stopped for two days, the state of each of the displays 3n, 3o is changed in the opposite direction to the above when the off time has elapsed. The on-control is stopped for the set number of times (days). That is, the lighting / flashing state of the indicators 3n, 3o represents the number of operations of the schedule key 3k, and the number of operations is subtracted by the off time. When the schedule key 3k is pressed over a predetermined number of times (pressed three times in the present embodiment), the display 3p is turned on, the set number of times for stopping the schedule control is canceled, and the schedule control is stopped (illumination). The schedule control ON control is continuously prohibited and only the OFF control is executed). If the schedule key 3k is further pressed while the display unit 3p is in a lighting state (schedule control is stopped), the display unit 3p is turned off (also 3n and 3o), thereby executing normal schedule control. .
Further, when the special program 1 or 2 is set, the special program 1 or 2 can be executed instead of the normal schedule.
As a result, status such as prohibition of schedule control can be displayed in an easy-to-understand manner, and normal schedule control is automatically performed after prohibition of on-control for the set number of times (days) or control according to a special program. It becomes possible to return to.

The operation when the schedule key 3k is operated to stop the schedule control for one day or two days and when the control is performed by the special programs 1 and 2 will be described based on specific examples.
FIG. 16 is a diagram showing an operation example when the schedule control is stopped without setting a special program. (A) is a case where the schedule key 3k is pressed once, and (b) is a case where it is pressed twice. It is a time chart for demonstrating the schedule control operation at the time. Here, it is assumed that the control schedule is set so that it is turned on (lighted) at 10:00 (on time) and turned off (lighted off) at 22:00 (off time) every day.
In the present invention, the off time is not limited to the case where the on time and the off time belong to the same day, for example, the on time is 10:00 and the off time is 5:00 on the next day. It may be the case the next day. That is, in the present invention, the period from the on time to the next on time is treated as one day.
Further, the present invention may be applied daily from on time to off time, and can also be applied to the case where on / off control is performed a plurality of times within 24 hours.

(Schedule control 1 day stop)
FIG. 16A is a time chart when the schedule control is stopped for one day. This corresponds to a case where the holiday is one day.
Assume that the schedule key 3k in FIG. 4B is pressed once at the time (1) between the on time and the off time of the normal schedule (lighting of the showcase 2 is on). This time (1) is, for example, during the business hours the day before the holiday. By this operation, step S201 (FIG. 8) is YES, S202 is YES, and the one-day stop indicator 3n is turned on (continuous lighting) (S203). At this time, the lighting-on state of the showcase 2 by schedule control is continued as it is. In this example, since special program control is not performed, the special program 1 is not set in S204, and S205 is NO. In addition, when the timing at which the schedule key 3k is operated is between the off time and the on time of the normal schedule (after the business hours on the day before the closed day), the indicator 3n changes from the lighting state to the blinking state ( S207, S208).

After that, when the current time becomes the schedule off time (2) (22:00 on the current day), the lighting of the showcase 2 is turned off, and the display 3n of the one-day stop is blinked, and the next schedule control is performed. Displays that the on-control is prohibited. That is, S311 in FIG. 11 is NO, S312 is YES, S313 is YES, and S314 is executed. Thereafter, the schedule control ON control is not executed even when the time becomes the normal schedule ON time (in this example, 10:00 on the next day). That is, in FIG. 15, S404 is YES, but the ON command is not transmitted to the electronic controller 1 because the current time and the normal schedule ON time are not compared. In FIG. 16A, the dotted line indicates that the on control is prohibited.
Then, the normal schedule off time (3) (22:00 on the next day) is reached, and the one-day stop indicator 3n is turned off when the one-day stop control is completed. That is, S311 in FIG. 11 is YES, S316 is NO, S321 is NO, and S319 is executed. As a result, all the indicators 3n to 3p are turned off, and the normal schedule control is resumed.

(When schedule control is suspended for 2 days)
Next, the control operation when schedule control is stopped for two days will be described. This corresponds to a case where the holiday is two consecutive days.
FIG. 16B is a time chart when the schedule control is stopped for two days.
When the schedule key 3k in FIG. 4B is pressed twice at time (1) between the on time and the off time of the normal schedule (lighting of the showcase 2 is on), the determination unit 27 has two days. The stop indicator 3o is turned on (continuous lighting). That is, when the schedule key 3k is pressed once, the daily stop indicator 3n is turned on as described above (S203 in FIG. 8). Subsequently, when the schedule key 3k is pressed once, S202 in FIG. 8 is NO, S209 is YES, S210 is executed, the 1-day display 3n is turned off, and the 2-day display 3o is displayed. Lights up. At this time, the lighting-on state of the showcase 2 by schedule control is continued as it is. Here, since special program control is not performed, the special program 2 is not set in S211, and S212 is NO. When the current time is between the off time and the on time of the normal schedule, the display device 3o changes from the continuous lighting state to the blinking state (S215).

Thereafter, when the current time is the off time of the normal schedule indicated by (2) (22:00 on the current day), the lighting of the showcase 2 is turned off, the indicator 3o for 2 days off is blinked, and The fact that the next schedule control ON control is prohibited is displayed. That is, S331 in FIG. 12 is NO, S332 is YES, S333 is YES, and S334 and S335 are executed. In this state, even if the time is the normal schedule on time (in this example, 10:00 the next day), the schedule control on control is not executed. That is, in FIG. 15, even if S408 is YES, the current time is not compared with the normal schedule on time, and the on command is not transmitted to the electronic controller 1.
Then, when the normal schedule off time of the next schedule shown in (3) is reached (22:00 on the next day), the 2-day stop indicator 3o is turned off due to the fact that the 2-day stop is stopped, and the next schedule In order to indicate that the on-control of the control is prohibited, the indicator 3n that is stopped for one day is blinked. That is, S331 in FIG. 12 is YES, S336 is NO, S342 is NO, and S339 to S341 are executed.
When the next normal schedule off time shown in (4) is reached (22:00 on the next day), the one-day stop indicator 3n is turned off because the one-day stop control is completed. That is, S311 in FIG. 11 is YES, S316 is NO, S321 is NO, and S319 is executed. As a result, all the indicators 3n to 3p are turned off, and the normal schedule control is resumed.

As described above, when a special program is not set, the schedule key 3k is pressed once to prohibit the next day's schedule control from being turned on. By pressing the schedule key twice, the next day and the day after next two days. On-control of schedule control can be prohibited. When the prohibition period elapses, the normal schedule control can be automatically resumed.
Therefore, the operator can respond to a closed day by a simple operation of operating the schedule key 3k on the day before or after the closed day.

Next, the operation when the special programs 1 and 2 are set will be described with reference to the time chart of FIG.
(When schedule control 1 day is replaced with special program 1)
FIG. 17A is a time chart in the case where the schedule control for one day is replaced with the special program 1 and executed. Here, as in the example shown in FIG. 5A, it is assumed that a special program 1 having an on time of 9:30 and an off time of 1:30 (next day) is set. .
As in the case of FIG. 16A, it is assumed that the schedule key 3k is pressed once at a time point (1) between an on time and an off time of a normal schedule. As a result, the indicator 3n that is stopped for one day is lit (continuously lit) as described above. In this case, in the special program input process in S204 of FIG. 8, the special program 1 is turned on and off. That is, S230 in FIG. 9 is YES and S235 is YES, and the set on time and off time of the special program 1 are stored in the schedule time storage unit of the storage unit. Here, as in the example of FIG. 5A, it is assumed that 9:30 is set as the on time and 1:30 as the off time of the special program 1. Since the time point (1) is before the normal schedule off time, S206 (FIG. 8) is NO, and the display 3n remains lit.

When the current time is the normal schedule off time (2) (22:00 on the current day), the lighting of the showcase 2 is turned off as described above, and the one day stop indicator 3n blinks. Become.
Thereafter, when the current time becomes the ON time of the special program 1 (9:30 on the next day), in the ON output process (FIG. 15), S401 is NO, S404 is YES, S405 is YES, and the storage unit 23 The ON time of the stored special program 1 is cleared (S406), and an ON command is transmitted from the electronic controller 1 (S407), and the illumination of the showcase case is turned ON.
Then, when the current time becomes the off time (1:30 on the next day) (3 ′) of the special program 1, in the off output processing 1 (FIG. 11), S311 is YES, S316 is YES, S317 is NO, The off time of the special program 1 in the storage unit 23 is cleared (S318), the display 3n is turned off (S319), an off command is transmitted to the electronic controller 1 (S320), and the illumination of the showcase 2 is turned off. Is done.
After this, since all the indicators 3n to 3p are turned off, normal schedule control is performed.

(When executing 2 days of schedule control with special programs 1 and 2)
FIG. 17B is a time chart when the schedule control for two days is replaced with the special programs 1 and 2 and executed. Here, as in the example shown in FIG. 5B, the special program 1 has an on time of 9:30, an off time of 1:30, and the special program 2 has an on time of 9:30. A description will be given assuming that the time is set at 21:30.
As in the case described above, it is assumed that the schedule key 3k is pressed once at the time point (1) between the on time and the off time of the normal schedule. Thereby, as described above, the indicator 3n stopped for one day is turned on. Then, in the special program input process of S204 of FIG. 8, the on time (9:30) and off time (1:30) of the special program 1 are set, and the schedule time storage unit of the storage unit 23 is set. It is stored (S230, S235, S236 in FIG. 9).
Subsequently, when the schedule key 3k is pressed once more, as described above, the one-day stop indicator 3n is turned off, and the two-day stop indicator 3o is turned on (YES in S201 of FIG. 8). , S202 is YES, S209 is YES).
Then, in the special program input process of S211, an operation for setting the on time and the off time of the special program 2 is performed. That is, S230 of FIG. 9 is NO, S231 is YES, S232 is YES, and the on time (9:30) and off time (21:30) of the special program 2 are stored in the schedule time storage unit of the storage unit 23. (S233).

Then, when the current time is the normal schedule off time (2) (22:00 on the current day), the display of the showcase case 2 is turned off and the two-day display 3o is blinking as described above. (S331, S332, S333, S334, and S335 in FIG. 12 are executed).
Thereafter, when the current time becomes the on-time of the special program 2 (9:30 on the next day), in the on-output process (FIG. 15), S401 is NO, S404 is NO, S408 is YES, and S409 is YES. The on time of the program 2 is cleared (S410), and an on command is transmitted to the electronic controller 1 (S407), and the illumination of the showcase 2 is turned on.
Thereafter, when the current time becomes the off time of the special program 2 (21:30 on the next day) (3 ′), in the off output processing 2 (FIG. 12), S331 is YES, S336 is YES, S337 is NO, The off time of the special program 2 is cleared (S338), the indicator 3o stopped for 2 days is turned off (S339), an off command is transmitted to the electronic controller 1, and the illumination of the showcase case 2 is turned off (S340). ) The indicator 3n that is stopped for one day is made to blink.

When the special program 1 is turned on (9:30 on the following day), in the on output process (FIG. 15), S401 is NO, S404 is YES, S405 is YES, and the special program 1 is turned on. When cleared (S406), an on command is transmitted to the electronic controller 1 (S407), and the illumination of the showcase 2 is turned on.
Thereafter, when the special program 1 is turned off (1:30 on the next day) (4 '), in the off output processing 1 (FIG. 11), S311 is YES, S316 is YES, S317 is NO, The off time of the program 1 is cleared (S318), the one day stop indicator 3n is turned off (S319), an off command is transmitted to the electronic controller 1 (S320), and the illumination of the showcase 2 is turned off. The
After that, since each of the indicators 3n to 3p is turned off and the special programs 1 and 2 are cleared, normal schedule control is performed.
Thus, according to the present invention, when a special program is set, it is possible to perform control by a special program instead of the normal schedule, and after the control by the special program is performed, Thus, it is possible to return to the normal schedule control state.

FIG. 16B shows a case where the 2-day schedule control is stopped, and FIG. 17B shows a case where the 2-day schedule control is replaced with the special programs 1 and 2. It is also possible to stop the daily schedule control during the day and replace the other daily schedule control with a special program.
FIG. 18 is a diagram showing an example of performing such control. FIG. 18A shows a case where the schedule control on the first day is replaced with a special program and the schedule control on the second day is stopped. It is a figure which shows the case where the schedule control of the 1st day is stopped and the schedule control of the 2nd day is replaced with a special program.
As in FIG. 17B, when the schedule key 3k is pressed twice, the special program 1 on time and off in the special program input process (S204 in FIG. 8) after the first press. When the special program 2 on time and off time are set in the special program input process (S211) after the second press without setting the time, as shown in FIG. The special program 2 is executed on the day, and schedule control is prohibited on the second day.
Also, in the special program input process (S204) after the first press of the schedule key 3k, the special program 1 on time and off time are set, and the special program input process after the second press is performed. When the on time and off time of the special program 2 are not set in (S211), as shown in FIG. 18B, the schedule control is prohibited on the first day and the special program on the second day. 1 will be executed.

In the above-described embodiment, when a special program is set, the day when the special program 1 set first is executed (the next day in the above example) is the special program 2 set later. However, on the contrary, a special program set first may be executed first and a special program set later may be executed later. . In this case, the blinking order of the indicators 3n and 3o may be reversed.
In the above-described embodiment, the schedule time storage unit of the storage unit 23 is provided with an area for storing the on time and off time of a special program so that control by the special program can be executed. However, the function of setting a special program can be omitted to make the configuration simpler. In this case, only the function of prohibiting the on-control of the schedule control a predetermined number of times is provided.
Further, in the above-described embodiment, two special programs 1 and 2 can be set. However, more special programs may be set or one special program may be set. Only a simple program may be set.

Furthermore, in the above description, it has been described that the lighting of the showcase 2 controlled by the schedule control is one (shelf lighting). Usually, the showcase 2 has shelf lighting and a work lamp (canopy). There are two types of lighting. FIG. 4B shows a form in which the work lamp (canopy) is turned on / off manually by a key (canopy).
This work light can be executed by the schedule control together with the shelf lighting. For example, when the work light is controlled by the schedule control together with the shelf lighting, the work light is first turned on before a predetermined time (for example, 30 minutes) of the normal schedule on time, and then the shelf is turned on at the on time. Perform on control on the lighting. Further, the off control of the schedule control may be a mode in which the off control is first executed on the shelf lighting at the off time, and the control for executing the off control on the work light after a predetermined time (for example, 30 minutes) may be added.
As another control mode, schedule times for work lights and shelf lighting may be stored independently so that independent schedule control can be executed.
