Description

  The present invention relates to a mode setting method by key input, and more particularly to an apparatus that selects an operation mode by a combination of long pressing of a specific key and key operation.

  Conventionally, for example, a data input device shown in FIG. 4 is disclosed as a device having a method for selecting an operation mode by long-pressing a specific key.

  FIG. 4 is a front view of the data input device. 71 is a keyboard body, 72 is a character key for inputting various data, 73 and 74 are indicators that output and display the current key input mode according to the value of a timer provided in the keyboard body 71, and 77 is a display. It is a nameplate in which various key input modes are entered at positions corresponding to the devices 73 and 74.

  A method of key input using such a configuration will be briefly described. For example, assume that the current mode is the lowercase mode and the operator wants to switch to the uppercase mode.

  Therefore, the operator keeps the key “A” on (pressed) for 2 seconds or longer and within 3 seconds. In this case, the indicator which lights up corresponding to the key input mode written in the nameplate 77 changes in order corresponding to the time when the key is ON. Therefore, the operator can input the desired data by confirming that the indicator of the desired key input mode is turned on and releasing the press of the character key 72.

  This method will be described in detail. FIG. 5 is a time chart showing the relationship between the contents of the key input mode and the indicator that lights up.

  An operator who performs data input inputs desired data by operating a character key 72 provided on the upper surface of the keyboard body 71. Here, when the operator wants to input data by switching the key input mode, the character key 72 is continuously pressed for a predetermined time corresponding to each mode.

  As shown in FIG. 5, the selection of each mode is determined by the pressing time of one character key. That is, in the key input pattern A that is a normal key operation as shown in FIG. 5 (1), the key is turned ON / OFF within one second. As will be described later, according to a preselected uppercase / lowercase mode. The key code of the input character key is determined.

  On the other hand, in the key input pattern B which is the lowercase mode switching operation as shown in FIG. 5 (2), when the key ON time is 1 second or longer and within 2 seconds, the mode is switched to the lowercase mode and the input character key is changed. The key code is determined. In addition, in the key input pattern C which is the capital letter mode switching operation as shown in FIG. 5 (3), when the key ON time is 2 seconds or longer and within 3 seconds, the mode is switched to the capital letter mode and the input character key is changed. The key code is determined.

  As described above, when the operator is consciously operating the ON time of one key, a plurality of modes can be assigned to one key and used (see, for example, Patent Document 1).

  In addition, since the lighting of the display device is configured to circulate and change, even if the operator fails to release the character key 72, data can be input accurately.

  Incidentally, as another method of assigning and using a plurality of modes to one key, there is a time chart shown in FIG. This is not a selection based on the ON time of one key, but a mode is selected based on the number of times one key is turned ON / OFF within a prescribed time.

  Such a method is adopted by portable music players and the like, and by repeatedly hitting the “play” button, it is possible to sequentially start from the beginning of a plurality of stored music lists or in reverse order from the end of the list. It is something to regenerate. In FIG. 6, the mode determination period, which is a period for counting the number of times the key is repeatedly hit, is 1 second, and the mode is selected according to the number of times the key is turned ON during this period.

  FIG. 6 (1) shows normal key operation, and playback is started from the current song position by performing key input once within the mode determination period. FIG. 6 (2) shows a list head designation operation, and reproduction is performed in order from the head of the music list by performing key input twice during the mode determination period. FIG. 6 (3) shows a list end designation operation, and reproduction is performed in reverse order from the end of the music list by performing key input three times within the mode determination period.

  An air conditioner shown in FIG. 7 is applied as one of the two types of mode selection methods described above.

  The indoor unit 80 of the air conditioner shown in FIG. 7 is a horizontally long box, and a cover 82 having a suction grill 87 is attached to a suction port 81 on the front surface to cover an internal structure. In addition, a plurality of vertical wind direction plates 84 are arranged at the horizontally long outlet 83 provided below. A light receiving window 85 for receiving an infrared signal from the remote controller 90 is provided below the right end of the indoor unit 80 so as to guide the infrared signal to a remote control receiver (not shown) inside the indoor unit 80. A forcible operation button 86 is provided below the right end of the cover 82 and is exposed when the cover 88 is opened.

  The remote controller 90 is formed in a vertically long box shape, and an infrared light emitting unit (not shown) that is sent to the indoor unit is provided at one end in the longitudinal direction.

  The plane portion of the remote controller 90 includes a display unit 91 made of a liquid crystal panel and a key input unit 92 having a plurality of keys arranged in front of it.

  When the operator presses the key input unit 92 of the remote controller 90, the operation mode of the air conditioner is switched or the set temperature is changed. These operation modes and set temperature information are displayed on the display unit 91 and transmitted to the indoor unit 80 via an infrared signal. The indoor unit 80 that has received the infrared signal operates the air conditioner so that the current room temperature information detected by the indoor unit 80 becomes the target set temperature set by the operator.

  The main body of the indoor unit 80 provided with the remote controller 90 is provided with a forced operation button 86 that is used urgently when the corresponding remote controller breaks down or the battery is exhausted. The forced operation button 86 is composed of one key switch, and starts automatic operation only by pressing once even without the remote controller 90, and stops operation by pressing again during automatic operation. Therefore, the remote controller 90 can be temporarily substituted until the remote controller 90 can be used again.

  The automatic operation here refers to the operation that automatically selects the cooling or heating operation mode corresponding to the room temperature when the operation is started, but in the cooling or heating operation mode such as spring or autumn. When it is difficult to determine, automatic operation may result in operation contrary to the operator's intention, and in order to avoid this, in addition to the automatic operation mode, forced heating operation mode and forced cooling operation mode are arbitrarily set Some can be selected.

  Accordingly, a key switch corresponding to these modes may be provided, but a plurality of functions are often assigned to one key due to low usage frequency, few key switch arrangement locations, and cost problems. For example, an automatic operation mode, a forced heating operation mode, a forced cooling operation mode, and an operation test mode for checking the operation of the device are assigned to one key switch (forced operation button 86) of the air conditioner of FIG. Yes. Therefore, the selection of these modes includes either the above-described selection by the long press time in FIG. 5 or the selection by the number of key inputs in a certain time in FIG.

  However, as shown in FIG. 5, in the mode selection by the long press time of one key, in order to check the long press time (selection mode), it is necessary for the operator to check the lighting of the display, and the display must be provided. As a result, the cost of the equipment was increased. In addition, a space for providing a display is also necessary, which is inappropriate for small-sized devices. On the other hand, there is a method of relying on the operator's can for the long pressing time of the key without providing a display, but there is a case where the accurate pressing time cannot be recognized and the intended setting cannot be made.

In addition, in the method of repeatedly hitting one key within the mode determination period as shown in FIG. 6, it is not necessary to provide a display, but it is agile to input a plurality of keys within a short mode determination period. Operation was necessary. On the other hand, when the mode determination period is lengthened, there is a problem that it is impossible to distinguish the normal key operation repeatedly.
Japanese Patent No. 2650409 (2nd page, FIG. 1)

  The present invention solves the above-described problems, and even if there is no display or the like that can confirm the current mode, a plurality of functions can be easily selected with one key, and an agile operation is not required. The purpose is to provide equipment that can be used.

In order to solve the above-described problem, the present invention includes a switch that is opened and closed, and a control unit that inputs an open / closed state of the switch as a switch state signal, and the control unit starts from the time when the switch is closed. A period until the time when the switch is opened is stored as a determination time designation period, and the switch state signal is stored immediately after the switch is opened and during the time from the time when the switch is closed until the time when the switch is opened. Is monitored , the number of times the switch is closed within the monitoring period is counted, and the operation mode is determined based on the count value.

Furthermore, it has an alerting | reporting means which outputs a sound signal according to the instruction | indication of the said control means, and outputs the said sound signal from the said alerting | reporting means regularly in at least one period of the said determination time designation | designated period or the said monitoring period .

By using the above means, according to the device provided with the operation mode selection means according to the present invention, the invention according to claim 1 allows the operator to arbitrarily determine the period for repeatedly pressing the key, and to the operator's preference. Correspondingly, the optimum time can be set, and as a result, the operability is good and the mode can be selected accurately.

According to the second aspect of the invention, in the determination time designation period and the monitoring period, sound and voice are periodically generated, and the time interval is recognized by the operator. Accuracy can be improved.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail as examples based on the attached drawings.

  As shown in the main block of the air conditioner in FIG. 1, the indoor unit 20 includes a remote control receiver 21 that receives an infrared signal transmitted from the remote controller 90, a room temperature sensor 27 that detects the indoor temperature, and a room temperature sensor 27. A room temperature sensor input unit 25 for inputting the detection signal, a notification unit 22 which is a notification means for generating a buzzer sound according to the input instruction, a blower fan motor 23, a stepping motor 24 for adjusting the angle of the vertical wind direction plate, A key input unit 28 that converts the ON / OFF state of the forced operation button 86 formed of a switch into a switch state signal and outputs the switch state signal, and an indoor unit control unit 26 that is a control means for controlling these are provided. Note that the indoor unit control unit 26 communicates with the outdoor unit 30.

  The indoor unit control unit 26 controls the entire air conditioner according to the operation mode and set temperature set by the remote controller, and monitors the ON / OFF state of the forced operation button 86 via the key input unit 28. When the forced operation button 86 is pressed during operation, the operation is stopped, and when the forced operation button 86 is pressed during operation stop, four modes are selected and executed corresponding to the key operation.

  These four modes and the selection method will be described with reference to the explanatory diagram of FIG. FIG. 2 is a time chart showing the operation of the forced operation button 86, where the LOW level of each signal indicates the ON state of the key, and the HIGH level of each signal indicates the OFF state of the key. These key inputs assume that the forced operation button 86 is pressed while the operation of the air conditioner is stopped.

  FIG. 2 (1) shows an operation for designating the automatic operation mode. If the ON time of the forced operation button 86 is “undecided period”, which is within 1 second here, the indoor unit control unit 26 is automatically operated by the operator. Recognize that the operation mode is specified and execute the corresponding operation. If the ON time of the forced operation button exceeds the “undecided period”, it is recognized that the specification is other than the automatic operation mode. Next, a selection method for three types other than the automatic operation mode will be described.

  In the specifying operation described below, regarding the ON / OFF of the forced operation button 86, the operation is performed separately for the determination time specifying period and the determination period. The determination time designation period is an ON period of a forced operation button that is arbitrarily performed by the operator for 1 second or longer, and designates a selection start instruction and a determination period described later. That is, the ON period time (determination time designation period) of the forced operation button 86 arbitrarily pressed by the operator is the determination period time.

  On the other hand, the determination period is a period during which an operation is actually designated, and a mode is selected based on the number of keys pressed during this period. For example, as shown in FIGS. 2 (2) to 2 (4), if there is a single key input (ON of the forced operation button 86) within the determination period, the forced heating operation mode is set, and within the determination period. If there are two key inputs, it is the forced cooling operation mode, and if there are three key inputs within the determination period, it is the operation test designation mode.

  In FIG. 2 (2), the determination time designation period and the determination period are X1 seconds, for example, 3 seconds. In FIG. 2 (3), the determination time designation period and the determination period are X2 seconds, for example, 2 seconds. In FIG. 2 (4), the determination time designation period and the determination period are X3 seconds, for example, 5 seconds.

  As described above, since the time of the determination period can be arbitrarily specified in the determination time specification period, in the case of an operator who is slow in operation, the determination time specification period is set longer, for example, 5 seconds, and the operation is quick. In the case of a simple operator, the determination time specification period is specified to be as short as 2 seconds, for example. The operator can designate the intended mode by performing the forced operation button ON a predetermined number of times during the judgment period that is the judgment time designated by the operator.

  Therefore, as described with reference to FIG. 6, there is no need to perform an operation within a uniquely determined mode determination time, the key operation during the determination period can be performed with a margin, and the mode can be selected reliably. . In addition, as described with reference to FIG. 5, it is not necessary to judge the key ON time for each uniquely determined mode with the operator's sense. The mode can be selected reliably.

  Also, the operator operates after determining the mode to be selected by himself. Therefore, for example, if the forced heating operation mode is intended, the determination time designation period can be designated as 1 second, for example. This is because the forced heating operation mode is selected with one forced operation button ON in the determination period, and the key operation time for mode selection can be adjusted in accordance with the selected mode.

  Note that the indoor unit control unit 26 may make a buzzer sound “every second” via the notification unit within a determination time designation period every time one second elapses. In this way, the operator can recognize that it is the determination time designation period, can know the progress within the determination time designation period, and can easily recognize the determination period.

  Further, the number of ringing may be increased with the passage of time, such as “beep, beep, beep”. In this case, it is possible to know how many seconds the determination time designation period is, and the determination period can be easily recognized. Furthermore, if the notification unit is configured so as to be able to output sound, the passage of time can be understood intuitively, such as “1 second, 2 seconds, 3 seconds”. Further, if the buzzer is similarly sounded during the determination period, the determination period can be easily recognized.

  Next, the flow of the key processing of the forced operation button 86 will be described using the flowchart of FIG. 3 representing the program executed by the indoor unit control unit 26. Also, in this flowchart, ST represents a step, the number following this represents a step number, Y represents Yes, and N represents No.

  In this flowchart, a routine for generating a buzzer sound every time one second elapses in a determination time designation period is shown in a separate frame, and the explanation is also divided. If this function is desired, the routines ST31 to ST32 may be inserted between ST3 and ST4 in the following description.

  As shown in FIG. 3, first, the indoor unit control unit 26 inputs the state of the forced operation button 86 from the key input unit 28, and checks whether the key is in an ON state (ST1). If the key is not ON (ST1-N), the process jumps to ST1. If the key is ON (ST1-Y), a timer in the indoor unit control unit 26 is started (ST2). This timer counts the specified determination time period.

  Next, the state of the forced operation button 86 is input from the key input unit 28, and it is confirmed whether the key is in an OFF state (ST3). If the key is not in the OFF state (ST3-N), the timer is read to check whether 10 seconds have elapsed (ST4). If the timer has not elapsed 10 seconds (ST4-N), the process jumps to ST3. If the timer has elapsed 10 seconds (ST4-Y), the timer is stopped (ST5) and the process jumps to ST3. In addition, since 10 seconds have been confirmed in ST4, the maximum value of the determination time designation period by the operator can be defined as 10 seconds.

  If the key is OFF (ST3-Y), the timer is stopped and the timer value is stored in the storage unit in the indoor unit control unit 26 (ST6). Then, the timer value is read to check whether the key ON time is within 1 second (ST7). If the key ON time is within 1 second (ST7-Y), the automatic operation start / stop is selected and executed (ST8), and the process jumps to ST1. Regarding the processing in ST8, as described above, the operation is stopped if it is already in operation, and the automatic operation is started if it is not in operation.

  On the other hand, if the key ON time is not within 1 second (ST7-N), the timer is initialized and started (ST9), and it is confirmed whether there is a key input (ST10). The key input here indicates a case where the forced operation button changes from OFF to ON to OFF.

  If there is no key input (ST10-N), the process jumps to ST12. If there is a key input (ST10-Y), the number of key inputs is incremented by 1 (ST11), and the process jumps to ST12. In ST12, the current timer value and the stored timer value, that is, the time of the determination period and the time of the determination time designation period are compared (ST12), and the current timer value and the stored timer value are the same. If not (ST12-N), jump to ST10.

  When the current timer value is the same as the stored timer value, that is, when the determination period is ended (ST12-Y), processing corresponding to the counted number of key inputs is executed (ST13). Then, jump to ST1. In ST13, the forced heating operation, the forced cooling operation, and the operation test are respectively performed when the number of key inputs is once, twice, and three times.

  Next, a routine for generating a buzzer sound every 1 second surrounded by a dotted frame will be described. When jumping from ST3-N, first, the indoor unit control unit 26 checks whether a unit time, for example, 1 second has elapsed since the forced operation button 86 was turned on (ST31). When 1 second of unit time has elapsed (ST31-Y), a buzzer sound is generated through the notification unit 22 (ST32). Then, the process jumps to ST4. If 1 second of unit time has not elapsed (ST31-N), the process skips ST32 and jumps to the next process.

  In this embodiment, the device using the key input of the present invention is described as an air conditioner. However, the present invention is not limited to this, and is widely applied to devices that cannot increase the number of keys, such as portable music players and mobile phones. it can. Moreover, although the alerting | reporting part is demonstrated as a buzzer, you may replace with an electronic sound or a voice synthesis | combination.

  In this embodiment, the determination time designation period and the monitoring period are the same length. However, the present invention is not limited to this, and the monitoring period may be twice or half the determination time designation period, or may have a specific relationship. If it is.
