Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a jigsaw puzzle in which a group of irregularly shaped pieces are fitted into the piece fitting recesses of a jigsaw plate and used for picture matching.

[Conventional technology]

Conventionally, in this type of jigsaw puzzle, in addition to the difficulty of fitting the piece group into the piece fitting recess, the competition of the assembly speed doubles the fun of the game. That is, by competing for the time (assembly time) until all of the piece groups are fitted into the piece fitting recesses, the game is enhanced and the fun is increased.

[Problems to be solved by the device] However, according to the conventional jigsaw puzzle, when competing for the assembly speed, the assembly time is known by looking at a clock, etc. It lacked its accuracy.

In addition, in order to increase its accuracy, a method of measuring the assembly time using a stopwatch can be considered, but in this case it is necessary to purposely prepare the stopwatch,
Also, the operation of manually stopping the stopwatch at the same time as the assembly is completed is troublesome. Further, there is a time lag between the timing when all of the piece groups have been fitted into the piece fitting recesses and the timing when the stopwatch is stopped, and a slight error remains in the measurement assembly time.

[Means for Solving the Problems]

The present invention has been made in order to solve such a problem, and is provided with a jigsaw table plate and a total fitting detecting means for detecting that all of the piece groups are fitted in the piece fitting concave portion. When the start switch and this start switch are turned on, the reset signal is supplied to clear the clock time, and after passing a minute time sufficient to clear the clock time, the delay circuit is passed. Is started by the start signal provided by the timer means, and the time counting operation is stopped based on the detected force of all fitting detection means, and a display for displaying the time counting time by this timer means. And a music generating means for playing a predetermined music based on the detection force of the all-fitting detecting means.

[Action]

Therefore, according to this invention, when the start switch is turned on when competing for the assembling speed, the time measured by the timer means is cleared, and the start signal provided via the delay circuit is prompted. When the time counting operation by the timer means is started and the time counting time by the timer means is displayed by the display means, and when all of the piece groups are fitted in the piece fitting recesses, the time counting operation by the timer means is started. The music is automatically stopped and the music generating means or the predetermined music starts to play.

〔Example〕

 Hereinafter, a jigsaw puzzle according to the present invention will be described in detail.

FIG. 2 is a plan view showing an embodiment of this jigsaw puzzle,
FIG. 3 is a plan view showing a jigsaw plate. In these figures, 1 is a jigsaw plate, 2 is mutually fitted in the same plane, and many pieces are fitted into a piece fitting recess 3 formed on the surface of the jigsaw plate 1 so that they can be disassembled and pulled out. , Which is a piece (piece group) of which the jigsaw puzzle 4 is configured with these as basic elements.

A start switch 5 and a display unit 6 are attached to the jigsaw plate 1, and a side face picture 7 of a rabbit wearing a top hat is printed on the bottom surface of the piece fitting concave portion 3 in accordance with the frame shape by printing or the like. It is displayed. Needless to say, the frame shape of the piece fitting concave portion 3 is not limited to the side profile of a rabbit, and various pictures such as landscapes and buildings can be displayed in the piece fitting concave portion 3.

Although the piece groups 2 have different shapes, the overall contour shape of the piece group 2 is substantially the same as or slightly smaller than that of the piece fitting concave portion 3 in a state where they are fitted to each other in the same plane. It is designed so that it can be disassembled and pulled out in the inside of 3. Here, in the present embodiment, an example is shown in which a group of 20 pieces (2A to 2T) forms a shape almost the same as that of the piece fitting concave portion 3, and the surface of each piece 2A to 2T. That is, for example, a character or the like of the story "Alice in Wonderland" is displayed on the upper surface when it is fitted into the piece fitting recess 3 according to the shape. And these pieces 2A
The optical sensors S1 to S20 are arranged at predetermined positions on the respective surfaces of the piece fitting recessed portion 3 facing the 2T to 2T.

The thick line in FIG. 2 shows the outline of each piece 2A to 2T, and the broken line in FIG. 3 shows the fitting virtual line of each piece 2A to 2T.

FIG. 1 is a block diagram showing a circuit incorporated in the jigsaw puzzle 4. When the start switch 5 is turned on, the timer 8 is provided with a reset signal for clearing the measured time, and the measured time is After a lapse of a minute time sufficient for clearing, a start signal for starting the time counting operation is given to the timer 8 via the delay circuit 9. The time measured by the timer 8 is digitally displayed on the display unit 6. On the other hand, the optical sensor S
1 to S20 send out a detection signal of "1" level when the input light to them is cut off, and each of the optical sensors S1 to S20
The detection signal from is supplied to the AND circuit 10. The signal of level "1" passing through the AND circuit 10 is given to the voice synthesis IC 11 and the timer 8 as a drive signal for driving the voice synthesis IC 11 and as a stop signal for stopping the time counting operation of the timer 8. Has become. In addition, the speech synthesis IC 11
Can be replaced with a buzzer or the like.

Next, in the jigsaw puzzle 4 configured as described above, a procedure for competing for the assembly speed will be described.
That is, the start switch 5 is turned on on the jigsaw plate 1 when starting the assembly from a state where all the pieces 2A to 2T have been extracted from the piece fitting recess 3. As a result, a reset signal is applied to the timer 8 to clear its time, and the start signal applied via the delay circuit 9 prompts the timer 8 to start the time counting operation. The measured time is digitally displayed on the display unit 6.

From this state, for example, when the piece 2A is fitted into the original fitting position in the piece fitting concave portion 3, the light input to the piece 2A is blocked by the piece 2A, and the optical sensor S is cut off.
The detected power of 1 becomes the "1" level. That is, the "1" level detection force is applied to the AND circuit 10 via the optical sensor S1. However, at this time, the detected forces of the other optical sensors S2 to S20 are at "0" level, and therefore the output of the AND circuit 10 maintains the "0" level state. In this way, for example, the pieces 2B, 2C, 2
If each piece is fitted into its original fitting position in the order of D ..., the optical sensors S2, S
The detection power of each optical sensor becomes "1" level in the order of 3, S4 ... And the detection power of this "1" level is successively applied to the AND circuit 10. Therefore,
When the last piece 2T is fitted, this piece 2T
By this, the input light to that is blocked, and the detected power of the optical sensor S20 becomes "1" level. As a result, all the inputs of the AND circuit 10 become "1" level, and this "1" level signal passes through the AND circuit 10 and is given to the voice synthesis IC 11 and the timer 8 as its drive signal and stop signal. Becomes That is, when all the piece groups 2 are fitted in the piece fitting recessed portions 3, at the same time, the voice synthesizing IC 11 plays music, and the timing operation of the timer 8 is stopped. Therefore,
The music played by the voice synthesizing IC 11 immediately appeals to the competitor that the assembly is completed, and the measured time remaining displayed on the display unit 6 at this time becomes the accurate measured assembly time.

As described above, according to the jigsaw puzzle of this embodiment, when competing in the assembling speed, it is only necessary to turn on the start switch 5, and all the pieces 2 in the piece fitting recess 3 are to be turned on.
When is fitted, the timer 8 automatically stops the timing operation at the fitting timing. At this time, by checking the remaining time displayed on the display unit 6, it is possible to accurately measure and assemble time. Will be able to get. Therefore, compared with the conventional method of measuring the assembly time by looking at the timepiece, or the method of measuring the assembly time using a stopwatch, the accuracy of the measured assembly time is increased and the assembly time is increased. This frees you from the hassles of measuring time.

In other words, when measuring the assembly time by looking at the clock, it is necessary to record the clock start time,
The jigsaw puzzle according to the present embodiment is not necessary because the timer 8 starts the timing operation at the same time when the start switch 5 is turned on. Further, when the assembly time is measured using a stopwatch, there is a time lag between the timing of fitting all of the piece group 2 into the piece fitting recess 3 and the timing of stopping the stopwatch. According to the jigsaw puzzle according to the embodiment,
Since the assembly completion timing and the timing operation stop timing are almost the same, there is no time lag, and an extremely accurate measurement and assembly time with less error can be obtained. Moreover, since the timer 8 automatically stops the timing operation when all of the piece group 2 is fitted in the piece fitting recessed portion 3, there is no need to manually stop the stopwatch upon completion of assembly. Absent.

In addition, in this embodiment, the optical sensors S1 to S1 are provided at predetermined positions on the respective surfaces of the piece fitting concave portion 3 facing the pieces 2A to 2T.
Although S20 is arranged, the photosensors may be arranged in a matrix with a resolution capable of detecting at least the smallest area piece of the pieces 2A to 2T.
Further, a magnet is embedded in each of the pieces 2A to 2T, a magnetic proximity switch is arranged at a predetermined position on each surface of the piece fitting recess 3 facing the magnet, or a mechanical contact such as a limit switch is provided in the piece fitting recess 3. It may be configured to be arranged at a predetermined position on each surface facing the pieces 2A to 2T. Further, when a plurality of pairs of light emitters and light receivers are arranged on the rising side surface of the piece fitting concave portion 3 and all the light between these light emitters and light receivers is blocked, all the piece groups 2 are placed in the piece fitting concave portion 3. It may be configured to detect that they have been fitted, and all fitting detection means for detecting that all of the piece groups 2 have been fitted into the piece fitting recess 3 are
There are various other possibilities.

[Effect of device]

As described above, according to the jigsaw puzzle of the present invention, when the start switch is turned on when competing for the assembling speed, the time measured by the timer means is cleared and the start provided through the delay circuit. The signal is prompted to start the time counting operation in the timer means, and the time counting time in this timer means is displayed by the display means,
When all of the group of pieces are fitted into the piece fitting recesses, the timing operation of the timer means automatically stops and the music generating means starts to play a predetermined music. Immediately, the completion of own assembly is appealed to the competitor, and the accurate measured and assembled time can be obtained from the displayed time measured.

Therefore, compared with the conventional method of measuring the assembly time by looking at the timepiece, or the method of measuring the assembly time using a stopwatch, the accuracy of the measured assembly time is increased and the assembly time is increased. This frees you from the hassles of measuring time.
