Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a timer main body is constituted by a polyhedron having one face that is always parallel to all the faces, and the timer body can be set in different ways depending on the mounting state of the polyhedron. This invention relates to a timer in which the timer is set at the same time as the time is set, and the set timer time is displayed on one side of a polyhedron.

In a conventional electronic timer configured to count one hour using a constant signal from a reference signal source, a switch is provided exclusively for setting the one hour timer and the timer cent, and the necessary switches are operated. By doing this, the timer was set to one hour and the timer was set. However, in the method using these operation switches, for example, when setting a timer, first,
One switch allows the timer to be set for one hour, another set of switches sets the timer for one hour, then the switch disables the timer one hour setting, and then the timer set/non-set switch allows the timer to be set for one hour. To set the timer and start the timer count, you have to operate many switches many times. Therefore, it is very time-consuming to operate, and there are a large number of switches.
Cost was also an issue.

Furthermore, in recent years, in order to reduce the number of switches in these timers, some have adopted a method in which a single switch has multiple functions. In addition to this, there was a drawback that the difficulty of operating the switch could not be improved.

In particular, timers often measure the number of minutes after the start of some operation, and with the conventional timers that require tedious operations, the timer is set to one hour at the time when measurement begins. This was a problem as the timer cents were often not delivered in time.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to make it possible to set the timer for one hour and set the timer without having to provide a number of operation switches on the timer and without performing troublesome operations. The goal is to provide such a timer.

In order to achieve the above object, the present invention comprises a timer main body as a polyhedron having one parallel face corresponding to all the faces, and furthermore, the timer body is constructed of a polyhedron having one face that is always parallel to each face, and furthermore, the timer body is constructed of a polyhedron having one parallel face corresponding to each face, and the timer body is configured to A group of operated switches, a timer counter that starts counting when at least one of the switches is turned on, and is configured such that the counting time differs depending on each switch that is turned on, and an output from the timer counter. By having a sound generation circuit that generates an alarm sound in response to a signal, by placing one side of the polyhedron as a mounting surface, setting of the timer for one hour and setting of the timer can be done simultaneously, and the timer for one hour is set. is determined by which side of the polyhedron is the mounting surface, and is a perspective view of a timer whose mounting surface is displayed by a display that displays a timer set on at least one side of the polyhedron for one hour. In one embodiment,
The main body of the timer is made up of a regular hexahedron, and one hour of the timer is displayed on the top surface in each mounting state.

As shown in FIG. 1, the timer main body 2 includes a frame 4 forming a regular hexahedron, and a switch plate 6 fitted into a portion corresponding to the surface of the frame 4 so as to protrude slightly. On this switch board 6, there is a numeral 8 that displays one hour of the timer.

The surface that was the mounting surface in the figure becomes the upper surface, and a display 8-6 for displaying rOFFJ is printed on the switch plate 6-6 fitted into this surface.

FIG. 4 is a cross-sectional view taken along the line A--A in FIG. 1, showing the configuration of the switches provided under each switch plate 6, with the internal circuit omitted.

An elastic movable piece 10 is attached to the back side of each switch plate 6, and the end of this movable piece 10 is attached to a substrate 12 attached to the frame 4. A pair of conductive parts' [F 14 a t

．． The substrate 12 constitutes a switch 18 that is turned on depending on the placement state of the timer main body 2.

Therefore, as shown in FIG. 1, when the timer body 2 is placed with the switch plate 6-4 facing down, the switch plate 6-4
is pressed, and the movable piece 10 is also suppressed, so that the conductive members 14a-4 and 14b-4 on the substrate 12 and the conductive member 16-4 in the movable piece 10-4 come into contact with each other, and the conductive member 1

3. 18-5 to 18-6 are in the off state. As a result, the timer counter of the electronic circuit (not shown) in the frame 4 is set to one hour for five minutes, and at the same time, the timer is set. And this set timer one hour is
Indicator "5" printed on the switch board 6-1 which is the top surface

As shown in FIG. 3, when the timer main body 2 is placed and the switch plate 6-1 is pressed, only the conductive members 14a-1 and 14b-1 are brought into conduction by the same operation as described above, and the switch Only 18-1 is turned on.

At this time, the timer counter is set to 0 minutes for one hour, that is, the one hour timer is not set, and the timer does not operate.

In this way, depending on the mounting state of the timer body 2, any one of the switch groups 18 is turned on and the timer time set in the evening differs. Further, the set one hour timer is displayed on a display 8 printed on a switch board 6 on the top surface of the timer body 2 placed thereon.

FIGS. 5 and 6 show a timer carafe 2209 and sound generation circuit 22. In particular, FIG. 5 is a circuit diagram of the switch 18 shown in FIG.
The input circuits connected to each of the switches 18-2 to 18-6 except for -1 are shown.

In FIG. 5, the input circuit is the chattering prevention circuit 2.
4. One-shot circuit 26.28. flip flop(
(hereinafter abbreviated as FF) 30, 32. and and gate 34
It consists of and. The timer counter 20 has five of these input circuits, the output signal of the switch 18-2 becomes the input signal, the switch 18-3 becomes the input signal A, the signal of the switch 18-4 becomes the input signal A, switch 18
-5 signal becomes input signal A3, and switch 18
The signal at -6 becomes the input signal A. These input signals An (n=1 to 5) are connected to a one-shot circuit 26 via a chattering prevention circuit 24. The output from chattering prevention circuit 24 is also connected to one input of AND gate 34 and to the input of FF 30. The other input of the AND gate 34 is connected to the Q output of the FF 30, and the output of the AND gate 34 is connected to the input of the FF 32. The output Q of the FF 32 is input to the one-shot circuit 28. Further, a constant periodic signal from a frequency dividing circuit 44 shown in FIG. 6 is inputted to the clock signal φ of the FFs 32 and 30.

FIG. 7 shows the input signals A2) from the switch groups 18-2 to 18-6, the output signal B of the one-shot circuit 26, the output signal Cn of the one-shot circuit 28, the constant period signal and

Using this time chart, each switch group 18-2~
The operation when any one of 18-6 is turned on will be explained.

When the switch plate 16 is pressed, the signal AnU L to H
stand up. Here, the chattering prevention circuit 24 is configured such that the output signal does not rise to H unless the input signal rises to H for a time T1 shown in FIG. Prevent malfunctions due to chattering. However, when the timer body 2 is placed on any one of the switch plates 16-2 to 16-6 as a placement surface, the input signal Anlti
It becomes H for more than T + time. As a result, an H signal is output from the chattering prevention circuit 24, and a positive single pulse is obtained from the output signal Bn of the one-shot circuit 26. After this, when a constant periodic signal rises, FF3
The output Q of 0 becomes H, and at the same time the AND gate 34
The output signal also becomes H. After this, when the constant periodic signal rises further, the signal En of the output Q of FF32 changes from L to H.
As a result, the output Cn of the output circuit 28
A single positive pulse is generated.

After this, when the switch 18 is turned off, the input signal An
falls from H to L, and along with this, AND gate 34
The output signal also falls from H to L.

After that, when the constant periodic signal rises, the signal En of the output Q of the FF 32 falls to L.

However, as shown in FIG. 7, if the signal An falls within two periods (indicated by T2) of the constant period signal, a positive single pulse is generated in the signal Bn, but F
Since the output of the AND gate 34 falls from H to L before a rising signal of a certain periodicity is input to the clock input φ of F32, the signals Cn and En maintain the L state.

In this way, the timer body 2 is placed and the switch 1
When any one of 8 is turned on for two or more periods of a constant period signal, a positive single pulse is first obtained in the signal Bn from the input circuit, and then, after a slight delay, a positive single pulse is generated in the signal Cn. Signal En rises to H.

FIG. 6 shows the timer ring 2° and the sound generation circuit 22 excluding the input circuits connected to each of the switches 18-2 to 18-6.

In FIG. 6, the timer counter 2o includes, in addition to the input circuit, an oscillator 361, a frequency divider 38, and a 40° second counter 42.

Each of them is configured to input an H signal.

Also, the carry signal from the second counter 44 is sent to the minute counter 4.
8, and the minute counter 48 also counts the minutes accordingly. The count output signal of the minute counter 46 is input to the AND gate group 52, and when the minute counter 48 counts 1 minute, an H signal is input to the AND gate 52-1, and when the minute counter 48 counts 2 minutes, the AND gate 52 -2 to H

In addition, a signal E1 from the input circuit shown in FIG. 5 is input to AND gates 50-1 and 5271, a signal E2 is input to AND gates 50-2 and 52-2, and A signal E is input to AND gates 52-3, a signal E4 is input to AND gates 50-4 and 52-4, and a signal E is input to AND gates 50-5 and 52-5. In addition to this, the AND gate group 50 has FF6
4 is inputted, and the inverted signal thereof is inputted to the AND gate group 52. The output of this AND gate group 50.degree. 52 is input to an OR gate 54.

On the other hand, signals C1 to C3 from the input circuit are input to the clock input φ of the FF 64 via the OR gate 58.
The output Q of the FF 64 is also input to the AND gate 62, and the inverted signal of the output Q of the FF 64 is input to the AND gate 60. Signals B1 to B via the OR gate 56 are also input to the AND gates 60 and 62. The output of the AND gate 60 is inputted to the frequency divider 382 and the reset manual R of the second counter 42 and the minute counter 46.
The output of the AND gate 62 is the frequency divider 409 second counter 4

The sound generation circuit 22 includes a gate circuit 66, a counter 68, and a notification circuit 70. It consists of AND gates 72, 74, and 76. The gate circuit 66 is a circuit that forms an alarm sound signal using the audible frequency signal from the frequency divider 38 and the intermittent frequency signal from the second counter 42, and this alarm sound signal is input to one side of the AND gate 76. The counter 68 is a counter that counts the alarm sound generation time based on a constant signal from the minute counter 46 via an AND gate 72, and its output is inverted and input to one of the AND gates 74. Further, the output of the OR gate 58 in the timer counter 20 is input to the reset manual R of the counter 68, and if a positive single pulse is generated in any one of the signals C1 to C5 from the input circuit, The count contents of the counter 68 are configured to be cleared.

On the other hand, the AND gate 7 to which the output of the counter 68 is input
4 is the OR gate 54 in the timer counter 20.
The output of AND gate 74 is input to the other of AND gates 72 and 76.

The operation of this circuit will be explained below using the time chart shown in FIG.

As shown in FIG. 1, when the switch board 6-5 on which the display 8-1 for displaying "5" is printed is placed facing upward, the switch board 6-6 on the bottom surface is pressed, and the switch board 6-5 is pressed. 1
8-6 is turned on. As a result, a positive single pulse is first obtained in the signal B6. The pulse is OR gate 5
6 to AND gates 60 and 62. In this state, if the signal F of the output Q of the FF 64 is L', a single pulse in phase with the signal B6 is obtained only at the output H of the AND gate 60, which causes the frequency divider 38° second counter 42 and minute counter The count contents of 46 are cleared and counting starts from the initial value.

After this, if the timer main body 2 is placed in the same state, the signal E6 becomes H and the AND gate 50-5.52-
5, the count contents of the counter 68 are cleared by the rising edge of a positive single pulse on the signal C0, and the FF
The signal F of the output Q of 64 rises from L to H, and as a result, only the AND gate 50-5 becomes open.

In this state, even if the user accidentally presses the switch plate 6-5 on the side, as long as the user releases his/her hand immediately, only a positive single pulse will be generated in signal B, as described above. Therefore, the signal E3 does not become H, and no positive single pulse is generated in the signal C3. The single pulse generated in signal B3 is then transmitted to OR gate 56. By simply clearing the count contents of the frequency divider 409 second counter 442 and minute counter 48 via the AND gate 62, and the AND gate group 52 to which the count output of the minute counter 48 is input is closed at this point, No malfunction occurs due to erroneously pressing the switch plate 6-3.

On the other hand, every minute that passes after the frequency divider 381 second counter 429 minute counter 46 restarts counting, the minute counter 46 outputs its output to In I21 l3114. From L to H in the order of Is. Therefore, when 5 minutes have passed, the output J5 of the minute counter 46 becomes H, and accordingly, the output J5. The output of the OR gate 54 becomes H. At this time, since the count content of the counter 68 has been cleared, its output becomes L, and therefore the output of the AND gate 74 becomes H. This result and gate 7
6 is opened, a signal in phase with the alarm sound signal from the gate circuit 66 is obtained at its output M, and an alarm sound is generated from the notification circuit 76. Still at the same time, AND gate 72 opens and counter 68 begins counting the constant signal from seconds counter 46. Then, after a certain period of time has elapsed, the output of the counter 68 rises to H, so the AND gate 74
The output becomes L, the AND gate 76 closes, and the alarm sound stops.

In this way, when the timer main body 2 is placed with the switch board 6-1 on which the display 8-1 displaying "5" is printed facing upward, the timer one hour is automatically set to 5 minutes. 0 to start the timer count Therefore, an alarm will sound 5 minutes after the set time.

Thereafter, when the switch board 6-3 on which the display body 8-3 displaying "3" is printed is placed with the switch board 6-3 facing upward, the switch board 6-5 is pressed and the switch 18-5 is turned on. This results in a single positive pulse on signal Bs, which pulse is transmitted to OR gate 56. Frequency divider 4 via AND gate 62
0. Reset input R for second counter 44 and minute counter 48
, clear these count contents, and start counting anew. After this, the signal E3 becomes H, and a positive single pulse is generated in the signal C8.

As a result, the counter 68 is cleared and its output becomes L, and the signal F of the output Q of the FF 64 becomes L. As a result, only the AND gate 52-3 is left open.

Frequency divider 402 Second counter 449 When three minutes have passed since the minute counter 48 restarted counting, the output N3 of the minute counter 48 becomes H, and accordingly, the AND gate 52-3
Output 03. The output of the OR gate 54 also becomes H, and an alarm sound is generated for a certain period of time in the same manner as before.

In this way, when the timer main body 2 is placed with the display 8-3 displaying "3" facing upward, the timer 1 hour is set to 3 minutes and the timer starts counting at the same time.

As shown in FIG. 3, the display 8 displays "OFF".
When the switch plate 6-1 is placed with -6 facing upward, the switch plate 6-1 is pressed, but at this time, the signals B, ~B,, c, ~C!
, El to E, nothing occurs. Therefore, the timer does not operate in this case.

In this way, according to this embodiment, the desired timer hour can be set by simply placing the display 8 with the printed side facing upward. At the same time, a timer is set, so there is no need for operating switches or their cumbersome operations.

The input circuit shown in FIG. 5 also includes a chattering prevention circuit 24. Since the FF 30 and the AND gate 34 prevent the timer from being set to one hour and setting the timer unless one switch 18 remains on for a certain period of time, the user may accidentally press the switch plate 6. Even if you do so, no malfunction will occur. There are two sets of counters that count one hour of the timer, and one of the counters starts counting immediately after the timer body 2 is placed.
Even if the input circuit provides time for determining whether the ON operation of the switch 18 is a malfunction, the timer setting time will not be disturbed by this.

In addition, the timer set for one hour is set when the timer is placed in the
This can be seen at a glance by looking at the top surface of the timer main body 2, which is made up of a regular hexahedron.

Furthermore, in this embodiment, one side of the timer body 2, which is made up of a regular hexahedron, is provided with a side that says "rQFF" which sets the timer hour to 0 minutes, that is, does not operate the timer, so a timer is normally not required. If you do not want to use the timer, or if you want to stop the timer midway, you can simply turn the side on which the display 8-6 that says "OFF" is printed face up. The switches 18 are turned on by pressing the switch plate 6 protruding from each side, and other switches, such as the timer body, are provided. It is also possible to provide a gravity switch that is turned on depending on the placement state of the device, or a touch switch may be provided on each surface.

Furthermore, in this embodiment, the timer main body is constructed of a regular hexahedron, but it is not limited to this regular hexahedron, but may be constructed of other regular polyhedrons that have one face that is always parallel to all the faces. It is possible to implement.

Furthermore, in this embodiment, a display 8 for displaying one hour of the timer is printed on the switch board 6, which becomes the top surface when placed, but the display 8 may be provided on another surface. The display body 8 may be composed of an electro-optical display element such as a liquid crystal instead of printing.

As described above, according to the present invention, there are a group of switches that are turned on in correspondence to one plane that is parallel to all the planes of the timer main body, and one of the switches of the switch group.
a timer counter that starts counting when a switch is turned on and whose counting time differs depending on each switch that is turned on; and a sound generation circuit that generates an alarm sound in response to an output signal from the timer counter. With this feature, you can set the timer for one hour and set the timer center at the same time just by changing the mounting state of the timer body, eliminating the need for conventional operation switches and their troublesome operations, making it extremely easy to use. A good timer can be provided. Further, since the set timer one hour is displayed on one side of the polyhedron constituting the timer body, the set timer one hour can also be easily recognized.
