Description

  The present invention relates to a timer, and more particularly to a timer suitable for use by students who take classes in a classroom or a gymnasium.

  Students who take classes in classrooms or gymnasiums often need a timer. For example, in classes such as mathematics and language in classrooms at schools and cram schools, drills, quizzes, hundreds of squares, group learning, study presentations, self-study schedules, break times, etc. (elapsed time and remaining time) In the class at the gymnasium, it is a time display such as game time, jump rope challenge, and training.

  Until now, no timer suitable for the above-mentioned applications has been found, and so-called kitchen timers for cooking have been well known so far, and this kitchen timer is currently used in classrooms and the like.

  On the other hand, in Patent Document 1 below, as a time measurement display device for presentations and conference presentations, a plurality of stages are continuously arranged in time series so that the end time of the previous stage becomes the start time of the current stage. The total elapsed time measuring unit that measures the first elapsed time that is the elapsed time from the start time of the first stage and the first remaining time that is the remaining time until the scheduled end time of the last stage are measured. The total remaining time measuring unit, the elapsed time measuring unit that measures the second elapsed time that is the elapsed time from the start time of each stage, and the second remaining time that is the remaining time until the scheduled end time of each stage are measured A remaining time measuring unit; a display unit that displays time information including the first elapsed time, the first remaining time, the second elapsed time, and the second remaining time; and a control unit that controls each of the measurement operations. Also with There has been disclosed.

  This time measurement display device is formed in a size that can be operated by a presenter with one hand so that the presenter can easily perform time management in a presentation or conference presentation. Further, an elapsed time measuring unit that measures a second elapsed time that is an elapsed time from the start time of each stage, and a remaining time measuring unit that measures a second remaining time that is the remaining time until the scheduled end time of each stage are: The measurement of the current stage is switched to the measurement of the next stage by the presenter's operation.

  However, the number of cooking timers as described above is small, so it cannot be seen from the whole classroom, so it is exclusively for teachers, and students can not grasp the elapsed time and remaining time and challenge time. I was not able to give my students a sense of motivation and a sense of accomplishment, and at the same time, they were unable to increase their own motivation.

  In group learning, a continuous timetable such as “Discussion 10 minutes—Summary 5 minutes—Presentation 3 minutes” was performed, but there was no timer that could display this continuously.

  Furthermore, conventional timers, such as cooking timers, have a tendency to make the lesson a management structure with strong management colors simply by letting them know the elapsed time and remaining time.

  On the other hand, it is conceivable to use a time measurement display device as shown in Patent Document 1 described above, but this is also dedicated to the presenter, and the time number display is small. In addition, in classrooms, for example, when conducting a small test of 3 questions, test 1 is solved in 3 minutes, each answer is answered in 1 minute, test 2 is answered in 3 minutes, each answer is answered in 1 minute, test It is often performed to repeat 3 consecutive timetables (3 minutes and 1 minute) (3 times), such that 3 is solved in 3 minutes and the answers are answered in 1 minute. In the described one, it is necessary to perform an operation for proceeding to the next consecutive timetable, and the number of repetitions cannot be set.

  Therefore, the present invention has been made in order to solve such a problem, and each student can see the time display and can repeatedly execute a continuous timetable continuously. It is intended to provide a timer suitable for use by students who receive it.

In order to achieve the above object, the present invention is a timer that has an operation unit and a display unit and is placed at a position that can be seen by each student who takes a lesson. While each display body is set to a size that can be viewed by each student, a plurality of count times set through the operation unit are stored in a memory, and the number of repetitions set through the operation unit is stored in the memory. And sequentially counting a plurality of count times stored in the memory based on a start operation input from the operation unit and displaying them on the display unit. a control means for controlling repeated by the number, wherein, der those characterized by having a function to perform a countdown display by using the display body at the start of the counting .

  Further, the display unit is characterized in that a magnet is provided on the back side of the casing provided on the front side.

  Further, the display portion is provided with a tripod mounting nut on the bottom surface side of the housing provided on the front surface.

  On the other hand, comprising a notification sound generating means for generating a notification sound, the control means stores in the memory the bell time set through the operation unit after the timer count time is set through the operation unit, Based on the start operation input from the operation unit, the timer count time is counted and displayed on the display unit, and when the pre-bell time stored in the memory is reached, the pre-bell is notified via the notification sound generating means. It is characterized by.

The control means is characterized by having a function to perform a countdown display by using the display body end Ryoji of the count.

  Furthermore, the control means displays the countdown time using the display body as the countdown display, and displays the lighting amount or the lighting position using the plurality of display bodies while the countdown time is switched. It is characterized by doing.

  Further, the control means executes a function of performing the countdown display when the power switch is turned on for a predetermined time or more when the power is turned on by turning on the power switch.

According to the present invention, each student who takes a class can see a time display, and can continuously execute a continuous timetable, which is convenient for group learning, presentations, self-study timetables, etc. It is suitable for use by students taking classes. Furthermore, since it has a function of performing a countdown display using a display body at the start of counting, it is possible to effectively make the student aware of the start of counting and prepare for arrival.

  In addition, since the magnet is provided on the back side of the housing, it can be used by being easily attached to the surface of a steel blackboard or whiteboard, thereby improving usability.

  In addition, by providing a tripod mounting nut on the bottom side of the housing, even in a gymnasium that has no teaching platform and no steel blackboard or whiteboard, it can be installed at the appropriate height in the desired location using a tripod. Can be used.

  On the other hand, since the pre-bell function is provided, the remaining time is also notified by sound, so that it can be particularly effective in group learning, presentations or speech contests.

Also, because it has a function to perform a countdown display using the display body count final Ryoji, it can effectively be transparent to terminate the count against the student, thereby preparing for its arrival.

  Further, as the countdown display, the display unit displays the countdown time, and while the countdown time is switched, the display amount is changed and the lighting amount or the lighting position is changed by using a plurality of display units. It has a characteristic countdown function that is effective in making the game start and end more effective and motivating to challenge like a game. The motivation to challenge can be improved effectively. For example, in a jump rope challenge, you can concentrate firmly at the beginning and end and fly firmly.

  In addition, since the function of performing the countdown display is executed when the power switch is turned on for a certain time or more when the power is turned on by turning on the power switch, the function can be easily used without complicated settings.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an external perspective view of a classroom timer which is an embodiment of a timer according to the present invention, and FIGS. 2 and 3 are a front view and a rear view thereof, respectively.

  The classroom timer 1 of the present embodiment has a case 2 having a horizontally long, substantially rectangular parallelepiped shape, and a display unit 3 is formed on the front surface using the majority of the case 2, and an operation is performed on the left end thereof. Part 4 is provided.

  The display unit 3 is composed of a 4-digit number display body 31 by a 7-segment LED (red LED) in a Japanese character array and a colon display body 32 arranged between the front and rear 2-digit number display body 31. , 99 minutes 59 seconds can be displayed. In the present embodiment, the case 2 has a width of 263 mm, a depth of 46 mm, and a height of 118 mm, the number display body 31 of the display unit 3 has a height of 70 mm, and is from the rearmost (up to 10 m) of the classroom. But it is set to a size that can be seen enough. In addition, as long as it is a size which can be visually observed from each student, it may be smaller or larger than this.

  The operation unit 4 has a power switch 41, a pre-bell key 42 and a program key 43 from the left on the upper side, a minute key 44 and a second key 45 from the left on the lower side, and a start in the center. / Stop key 46 is arranged. The pre-bell key 42 and the program key 43 function as a buzzer volume switching key when pressed simultaneously, and the buzzer volume at the end of the timer is strong, weak, or off (silent) each time the pre-bell key 42 and the program key 43 are pressed simultaneously. It has come to switch. The minute key 44 and the second key 45 can be fast-forwarded if they are kept pressed for 1 second or longer. These minute key 44 and second key 45 also function as a reset key when pressed simultaneously. Further, a buzzer hole 5 for emitting a notification sound of a buzzer (described later) incorporated therein is formed below the operation unit 4. A DC jack 6 for power supply for inserting a DC power plug of an AC power adapter (not shown) is provided on the side surface where the operation unit 4 and the buzzer hole 5 are provided.

  On the other hand, on the both sides of the lower surface of the housing 2, leg portions 7 for tabletop installation such as a teaching platform are formed to protrude, and the center portion of the lower surface is formed with a protruding amount smaller than that of the leg portions 7. A nut 8 is provided. By installing such a tripod mounting nut 8, even in a gymnasium where there is no steel board and no whiteboard to which the magnet described below is attached without a teaching platform, it is installed at the appropriate height position of the desired place using a tripod And can be used. The upper surface is provided with a larger start / stop key 46a having the same function as the above-mentioned start / stop key 46 of the operation unit 4 on the left side when viewed from the front side. Is configured to be easily performed.

  Also, as shown in FIG. 3, a pair of magnets 9 are attached to the back side of the housing 2 so that it can be easily attached to a steel blackboard or a whiteboard, improving usability. It has become. Further, a pair of wall-hanging holes 10 are formed inside each magnet 9 so that it can be installed on a wooden blackboard or the like where the magnet 9 cannot be used using wood screws or the like.

  FIG. 4 is a block diagram showing the internal configuration of the timer 1, and includes the power switch 41, preliminary bell key 42, program key 43, minute key 44, second key 45 and start / stop keys 46, 46a of the operation unit 4 described above. The operation output from is input to a microcomputer 11. Then, the key recognition unit 12 realized by the microcomputer 11 recognizes which key is operated. The output of the key recognition unit 12 is input to the calculation function unit 13 which is also realized by the microcomputer 11, and a stopwatch function, a timer function, a program timer function, and a countdown (including a count reader) function as shown in a flowchart described later. Etc. are executed. Note that these are realized by executing a program stored in a program memory built in the microcomputer 11 using a work memory built in the microcomputer 11.

  A drive clock signal CL obtained by dividing the oscillation signal from the oscillator 14 by the frequency dividing circuit 15 is input to the key recognition unit 12 and the calculation function unit 13 of the microcomputer 11. Based on this, the key recognition unit 12 and the calculation function unit 13 are driven. Then, the number display body 31 and the colon display body 32 composed of the 7-segment LED of the display section 3 are driven from the calculation function section 13 via the driver 16 to perform count display and the like. Further, the buzzer 18 is driven from the calculation function unit 13 via the driver 17 so that a buzzer sound such as the end of counting or a preliminary bell is emitted.

  Next, the control operation of the present embodiment will be specifically described with reference to the flowcharts shown in FIGS.

(Normal mode)
When the power switch 41 is normally pressed for a short time to turn on the power, the processing shown in the flowcharts of FIGS. 5 and 6 starts, and whether or not the start / stop key 46 or 46a is first pressed in the initial state. Is checked (step S1).

  Here, when the classroom timer 1 is used as a mere stopwatch, if the start / stop key 46 or 46a is pressed as it is (Y in step S1), up-counting starts from 0 minutes 0 seconds as a stopwatch (step S1). S2). The up-counting is continued until the next start / stop key 46 or 46a is pressed (N in step S3 → the loop in step S2). When the start / stop key 46 or 46a is pressed, the up-count is stopped there. The count time is also displayed in a stopped state (Y in step S3 → step S4).

  If the start / stop key 46 or 46a is pressed again while the up-count is stopped, the up-count is restarted from the stopped state (Y in step S5 → step S2). On the other hand, when the minute key 44 and the second key 45 are pressed at the same time while the up-count is stopped, the initial state is reset (Y in step S6 → step S7), and the process returns to the first step S1.

  On the other hand, when it is used as a timer and it is desired to set a preliminary bell, the timer time is set first. For example, to set the timer time to 5 minutes, the minute key 44 may be pressed 5 times. That is, when the minute key 44 is pressed instead of the start / stop key 46 or 46a in the initial state (step S1) (N in step S1 → Y in step S8), it is added to the timer time (initial value = 0). (Step S9). If the minute key 44 is pressed five times (Y in step S8 → N in step S9 → N in step S10 → N in step S28 → N in step S16 → Y in step S8 → Loop in step S9), the timer time setting is 5 Minutes.

  When the pre-bell key 42 is pressed here, the timer time is set to 5 minutes and the display on the display unit 3 is set to “0:00” to check whether the minute key 44 or the second key 45 has been pressed ( Y of step S10 → step S11). For example, if you want to ring the bells when the remaining time is 1 minute and 30 seconds, first press the minute key 44 to add 1 minute to the bell time (initial value = 0) and display “1:00”. (Y of step S11 → step S12). When the pre-bell key 42 is pressed here, the first pre-bell time (1 minute) set above is stored in the memory built in the microcomputer 11, and the pre-bell time is initialized (= 0) to display on the display unit 3. Becomes “0:00” (Y in step S13 → step S14). Next, when the second key 45 is pressed, 1 second is added to the initialized preliminary bell time (N in step S15 → Y in step S11 → step S12). When the remaining time is set to 30 seconds, the second key 45 may be pressed 30 times. However, the second key 45 may be pressed and held until the display on the display unit 3 becomes “0:30” (step S12 → step N of S13 → Y loop of step S11). When the pre-bell key 42 is pressed here, the second pre-bell time (30 seconds) set above is stored in the memory built in the microcomputer 11, and the pre-bell time is initialized (= 0) and displayed on the display unit 3. Becomes “0:00” (Y in step S13 → step S14). When the pre-bell key 42 is pressed again, the pre-bell setting is completed, and the display on the display unit 3 returns to “5:00” indicating the timer time set for 5 minutes (Y in step S15 → step S16).

  When the start / stop key 46 or 46a is pressed in this state, the down-count from the timer time set as 5 minutes starts (Y in step S16 → step S17). The count down of the timer time can also be stopped at the count time at the time of pressing by pressing the start / stop key 46 or 46a (Y of step S18 → step S19). If the start / stop key 46 or 46a is pressed again while the downcount is stopped, the downcount is resumed from the stopped state (step S19 → Y of step S20 → step S17).

  Further, when the pre-bell time set above is reached during the down-counting, the buzzer 18 is driven and a predetermined preliminary bell buzzer is emitted (N in step S18 → Y in step S21 → step S22). In the above, since the preliminary bell time is set to the remaining time of 1 minute and 30 seconds, the preliminary bell buzzer is emitted when the display on the display unit 3 becomes “10:00” and “0:30”. When the set timer time ends, the buzzer 18 is driven and a predetermined end buzzer different from the preliminary bell buzzer is issued (Y in step S23 → step S24).

  The timer set as described above can be repeatedly executed including the preliminary bell by pressing the start / stop key 46 or 46a even if it is once ended (Y in step S25 → step S26 → step S27). N → Step S16). When the timer is to be completely terminated, the minute key 44 and the second key 45 are simultaneously pressed to reset to the initial state (Y in step S27 → step S7), and the process returns to the first step S1.

  By providing such a pre-bell function, the remaining time is notified even by sound, so that it can be particularly effective in group learning, presentations or speech contests.

  On the other hand, when the minute key 44 or the second key 45 is pressed and the timer time is being added as described above (Y in step S8 → step S9), if the program key 43 is pressed instead of the preliminary bell key 42. (N in step S10 → Y in step S28), the process proceeds to step S29 shown in FIG. 6 as a program timer. Here, the timer time that has already been added (for example, 3 minutes “3:00”) is stored in the memory built in the microcomputer 11 as the program time, and the display unit 3 is initialized (= 0). Is displayed, and it is checked whether the minute key 44 or the second key 45 is pressed (step S29 → step S30). For example, if 1 minute is set as the program time of the program timer and then 1 minute is to be repeated, and the user wants to repeat this 3 times, first press the minute key 44 once to initialize the program time (= 0) ) Is added, and “10:00” is displayed on the display unit 3 (Y in step S30 → step S31). When the program key 43 is pressed here, the second program time (1 minute) set above is stored in the memory built in the microcomputer 11 and the program time is initialized (= 0) to display on the display unit 3. Becomes “0:00” (Y in step S32 → step S29). Next, when the pre-bell key 42 that also functions as a repeat count key is pressed, 1 is added to the repeat count (initial value = 0) and “1” is displayed on the display unit 3 (N in step S30 → N → Y of step S33 → step S34). Accordingly, when the pre-bell key 42 is pressed three times, the number of repetitions is three (N in step S35 → Y in step S33 → loop in step S34). When the program key 43 is pressed here, the number of repetitions (3 times) is stored in the internal memory of the microcomputer 11 and the first program time (3 minutes) is read out and “3:00” is displayed on the display unit 3. Is displayed (Y in step S35 → step S36 → step S37).

  When the start / stop key 46 or 46a is pressed in this state, the first program time (3 minutes) read out is counted down (Y in step S38 → step S39). When the down-counting of the first program time (3 minutes) is completed, the display on the display unit 3 becomes “0:00” and the buzzer 18 is driven to generate a predetermined program time end buzzer (Y in step S40 → Step S41). Then, it is checked whether or not there is a next program time continuously. Here, the next program time (1 minute) is read and displayed on the display unit 3 as “10:00”, and from there Is started (Y in step S42 → step S43 → step S39). When the down-count of the program time (1 minute) is completed, the display on the display unit 3 becomes “0:00” and the buzzer 18 is driven to generate a predetermined program time end buzzer as described above (step S40). Y → step S41). When the next program time runs out, the buzzer 18 is driven and a predetermined program time round end buzzer different from the program time end buzzer is issued (N in step S42 → step S44). Further, it is checked whether or not the number of repetitions (three times) set as described above has been completed. If the number of repetitions has not been completed, the first program time (3 minutes) is read again and the control operation described above is performed. Is repeated (N in step S45 → step S46 → step S39). When the set number of repetitions (three times) is completed, it is checked whether or not the start / stop key 46 or 46a has been pressed (Y in step S45 → step S47), where the start / stop key 46 or 46a is pressed. Then, the process returns to step S37, the first program time (3 minutes) is read, and “3:00” is displayed on the display unit 3. When it is desired to execute the set program timer again, if the start / stop key 46 or 46a is pressed here, the above-described series of program timers are executed again, but the start / stop is performed in either step S47 or step S38. When the minute key 44 and the second key 45 are pressed simultaneously instead of the stop key 46 or 46a, the initial state is reset (Y in step S49 → step S7), and the process returns to the first step S1. In the middle of setting the program timer, when the minute key 44 and the second key 45 are pressed at the same time instead of the preliminary bell key 42 for setting the number of repetitions, the initial state is reset (N → step S33). Y in step S48 → step S7), the process returns to the first step S1. Further, when the pre-bell key 42 and the program key 43 are pressed at the same time (N in step S1 → N in step S8 → Y in step S50), the buzzer volume is switched (step S51). Each time the program key 43 is pressed simultaneously, the buzzer volume switches between strong, weak, and off (silence).

  As described above, according to the present embodiment, in addition to the stopwatch and downcount timer in the general cooking timer, it has a program timer function for continuously executing a plurality of program times, so group learning and presentation, This is especially useful for self-study timetables. Moreover, since the number of repetitions can be set, as described in the above-mentioned background art, for example, when conducting a small test of 3 questions, test 1 is solved in 3 minutes and each answer is answered in 1 minute. , Test 2 in 3 minutes, answer each person in 1 minute, test 3 in 3 minutes, answer each person in 1 minute, and so on. It is possible to easily cope with the case of repeating (three times).

(Countdown mode)
When the power switch 41 is pressed for 2 seconds or longer when the power is turned on, a countdown mode (also referred to as a count reader) as shown in the flowcharts of FIGS. 7 and 8 and the explanatory diagram of FIG. 9 is set and activated. When the countdown mode is set, the countdown starts 3 seconds before the count starts and times up. The stopwatch function does not count down at the end because it is an upcount. For example, when the timer time is set to 10 minutes with the timer function, as shown in FIG. 9, the count display mode is set to the count display mode 31 for the second display unit 3 for 3 seconds before the start of the 10-minute down-count. From the state in which all the segment display LEDs of the outer peripheral part are lit in a horizontally long rectangular shape using all the numeric display bodies 31 while the seconds are switched to “2” and “1” after displaying “3” seconds. By adding a count reader function that turns off one by one and displays the next second after all the lights are turned off at the end, compared to a simple “3” → “2” → “1” countdown mode, Unique countdown (count reader) function as described above, which is effective for making students more aware of the start and end of counting and increasing their motivation to challenge like a game Because they have, it is possible to effectively improve the motivation to actively challenge to self-management and teaching issues by the students. For example, in a jump rope challenge, you can concentrate firmly at the beginning and end and fly firmly. The display mode of the countdown function is quite effective because it is sufficiently conspicuous. However, the display mode is not limited to this, and is a display mode that changes the lighting amount and lighting position of the numeric display body and the colon display body, for example, lighting in the horizontal direction. Even if the amount and the lighting position are changed, substantially the same effect as the above embodiment can be obtained. In addition, a certain effect can be expected even with a countdown display of only numbers.

  Further, when a plurality of program times and the number of repetitions are set by the program timer function, for example, as described above, when P1 is 3 minutes, P2 is 1 minute and the number of repetitions is 3 as described above, The first P1 counts down before the start and before the end, but P2 starts without counting down, counts down before the end of P2, and does not count down before the start of the second and subsequent P1. That is, the start countdown is performed only before the start of the first P1. The countdown mode is canceled when the power is turned off.

  Although there are many points that overlap the above description, specifically, when the processing shown in the flowcharts of FIGS. 7 and 8 is started, the start / stop key 46 or 46a is first pressed in the initial state as described above. It is checked whether or not it has been done (step S101).

  Here, when this classroom timer 1 is used as a mere stopwatch, if the start / stop key 46 or 46a is pressed as it is (Y in step S101), the countdown operation of 3 seconds as described above is executed, As a stopwatch, up-counting is started from 0 minutes 0 seconds (step S102 → step S103). The up-counting is continued until the next start / stop key 46 or 46a is pressed (N in step S104 → the loop in step S103). When the start / stop key 46 or 46a is pressed, the up-count is stopped there. The count time is also displayed in a stopped state (Y in step S104 → step S105).

  If the start / stop key 46 or 46a is pressed again while the up-count is stopped, the up-count is restarted from the stopped state (Y in step S106 → step S103). On the other hand, when the minute key 44 and the second key 45 are pressed at the same time while the up-count is stopped, the initial state is reset (Y in step S107 → step S108), and the process returns to the first step S101.

  On the other hand, when it is used as a timer and it is desired to set a preliminary bell, the timer time is set first. For example, to set the timer time to 5 minutes, the minute key 44 may be pressed 5 times. That is, when the minute key 44 is pressed instead of the start / stop key 46 or 46a in the initial state (step S101) (N in step S101 → Y in step S109), it is added to the timer time (initial value = 0). (Step S110). When the minute key 44 is pressed five times (Y in step S109 → N in step S110 → N in step S111 → N in step S131 → N in step S117 → Y in step S109 → Y loop in step S110), the timer time setting is 5 Minutes.

  When the pre-bell key 42 is pressed here, the timer time is set to 5 minutes and the display on the display unit 3 is set to “0:00” to check whether the minute key 44 or the second key 45 has been pressed ( Y in step S111 → step S112). For example, if you want to ring the bells when the remaining time is 1 minute and 30 seconds, first press the minute key 44 to add 1 minute to the bell time (initial value = 0) and display “1:00”. (Y in step S112 → step S113). When the pre-bell key 42 is pressed here, the first pre-bell time (1 minute) set above is stored in the memory built in the microcomputer 11, and the pre-bell time is initialized (= 0) to display on the display unit 3. Becomes “0:00” (Y of step S114 → step S115). Next, when the second key 45 is pressed, 1 second is added to the initialized preliminary bell time (N in step S116 → Y in step S112 → step S113). When the remaining time is set to 30 seconds, the second key 45 may be pressed 30 times. However, the second key 45 may be pressed and held until the display on the display unit 3 becomes “0:30” (step S113 → step N in S114 → Y loop in Step S112). When the pre-bell key 42 is pressed here, the second pre-bell time (30 seconds) set above is stored in the memory built in the microcomputer 11, and the pre-bell time is initialized (= 0) and displayed on the display unit 3. Becomes “0:00” (Y of step S114 → step S115). When the pre-bell key 42 is pressed again, the pre-bell setting is completed, and the display on the display unit 3 returns to “5:00” indicating the timer time set as 5 minutes (Y in step S116 → step S117).

  When the start / stop key 46 or 46a is pressed in this state, the countdown operation of 3 seconds as described above is executed, and then the countdown from the timer time set as 5 minutes starts (Y in step S117 → step S118). → Step S119). The count down of the timer time can also be stopped at the count time at the time of pressing by pressing the start / stop key 46 or 46a (Y in step S120 → step S121). If the start / stop key 46 or 46a is pressed again while the downcount is stopped, the downcount is restarted from the stopped state (step S121 → Y of step S122 → step S119).

  In addition, when the pre-bell time set above is reached during the down-counting, the buzzer 18 is driven and a predetermined pre-bell buzzer is emitted (N in step S120 → Y in step S123 → step S124). In the above, since the preliminary bell time is set to the remaining time of 1 minute and 30 seconds, the preliminary bell buzzer is emitted when the display on the display unit 3 becomes “10:00” and “0:30”. Then, when the set timer time is 3 seconds before the end, the countdown operation of 3 seconds as described above is executed, and when this is finished, the buzzer 18 is driven to generate a predetermined end buzzer different from the above-mentioned bell bell buzzer. (Y in step S125 → step S126 → step S127).

  The timer set as described above can be repeatedly executed including a preliminary bell by pressing the start / stop key 46 or 46a even if it is once ended (Y in step S128 → step S129 → step S130). N → Step S117). When the timer is to be completely terminated, the minute key 44 and the second key 45 are simultaneously pressed to reset the timer to the initial state (Y in step S130 → step S108), and the process returns to the first step S101.

  On the other hand, as described above, when the minute key 44 or the second key 45 is pressed and the timer time is added (Y in step S109 → step S110), if the program key 43 is pressed instead of the preliminary bell key 42. (N in step S111 → Y in step S131), the process proceeds to step S132 shown in FIG. 8 as a program timer. Here, the timer time that has already been added (for example, 3 minutes “3:00”) is stored in the memory built in the microcomputer 11 as the program time, and the display unit 3 is initialized (= 0). Is displayed, and it is checked whether the minute key 44 or the second key 45 is pressed (step S132 → step S133). For example, if 1 minute is set as the program time of the program timer and then 1 minute is to be repeated, and the user wants to repeat this 3 times, first press the minute key 44 once to initialize the program time (= 0) ) Is added to the display unit 3 and “10:00” is displayed on the display unit 3 (Y in step S133 → step S134). When the program key 43 is pressed here, the second program time (1 minute) set above is stored in the memory built in the microcomputer 11 and the program time is initialized (= 0) to display on the display unit 3. Becomes “0:00” (Y in step S135 → step S132). Next, when the pre-bell key 42 that also functions as a repeat count key is pressed, 1 is added to the repeat count (initial value = 0) and “1” is displayed on the display unit 3 (N in step S133). Y in step S136 → step S137). Accordingly, when the pre-bell key 42 is pressed three times, the number of repetitions is three (N in step S138 → Y in step S136 → loop in step S137). When the program key 43 is pressed here, the number of repetitions (3 times) is stored in the internal memory of the microcomputer 11 and the first program time (3 minutes) is read out and “3:00” is displayed on the display unit 3. Is displayed (Y in step S138 → step S139 → step S140).

  When the start / stop key 46 or 46a is pressed in this state, the count down operation of 3 seconds as described above is executed, and then the down count of the first read program time (3 minutes) is started (in step S141). Y → step S142 → step S143). Furthermore, when the first program time (3 minutes) is counted down 3 seconds before the end of the countdown, the display on the display unit 3 becomes “0:00” after executing the same 3 second countdown operation as described above. The buzzer 18 is driven and a predetermined program time end buzzer is issued (Y in step S144 → step S145 → step S146). Then, it is checked whether or not there is a next program time continuously. Here, the next program time (1 minute) is read and displayed on the display unit 3 as “10:00”, and from there Down-counting is started (Y in step S147 → step S148 → step S143). If the program time (1 minute) is 3 seconds before the end of the countdown, the same 3 second countdown operation as described above is executed and then the display on the display unit 3 becomes “0:00” and the buzzer 18 It is driven and a predetermined program time end buzzer is issued (Y in step S144 → step S145 → step S146). When the next program time runs out, the buzzer 18 is driven and a predetermined program time round end buzzer different from the program time end buzzer is issued (N in step S147 → step S149). Further, it is checked whether or not the number of repetitions (three times) set as described above has been completed. If the number of repetitions has not been completed, the first program time (3 minutes) is read again and the control operation described above is performed. Are repeated (N in step S150 → step S151 → step S143). When the set number of repetitions (three times) is finished, it is checked whether or not the start / stop key 46 or 46a has been pressed (Y in step S150 → step S152), where the start / stop key 46 or 46a is pressed. Then, returning to step S140, the first program time (3 minutes) is read and “3:00” is displayed on the display unit 3. When it is desired to execute the set program timer again, the series of program timers described above are executed again by pressing the start / stop key 46 or 46a. However, the start / stop is performed in either step S152 or step S141. When the minute key 44 and the second key 45 are pressed simultaneously instead of the stop key 46 or 46a, the initial state is reset (Y in step S154 → step S108), and the process returns to the first step S101. In the middle of setting the program timer, when the minute key 44 and the second key 45 are pressed at the same time instead of the pre-bell key 42 for setting the number of repetitions, the initial state is reset (N → step S136). In step S153 Y → step S108), the process returns to the first step S101. If the pre-bell key 42 and the program key 43 are pressed at the same time (N in step S101 → N in step S109 → Y in step S155), the buzzer volume is switched (step S156). Each time the program key 43 is pressed simultaneously, the buzzer volume switches between strong, weak, and off (silence).

  As described above, the classroom timer 1 according to the present embodiment is not a mere timer, and continuously executes a plurality of program times, and a program timer function capable of continuously executing a set number of repetitions. Because it has the characteristic countdown (count leader) function as described above, which is effective for raising the motivation to challenge like a game, it effectively improves the motivation to actively challenge students' independent management and class assignments. be able to.
