Description

[Detailed description of the invention] Purpose of the invention (field of industrial application) The invention relates to scissors that produce a melody.

(Problems to be solved by conventional techniques and inventions) Conventionally, scissors are generally used to cut cloth, etc., but these scissors only have a cutting function with their blades, and they can be enjoyed while cutting. There was a lack of consideration given to

Therefore, it may be possible to add a function to play a melody to the scissors. However, if the scissors have a built-in melody generator and a switch to turn it on and off is simply provided on the outside of the scissors, the user has to go out of his way to turn the switch on and off in order to listen to and enjoy the melody. It is expected that users will find the operation troublesome. Further, there is also the disadvantage that the switch is provided on the outside of the scissors, which makes it look unsightly.

The purpose of this invention is to make it possible to turn on and off the melody generator by opening and closing operations, which are the original movements of scissors, so that the user does not feel troublesome when turning on and off, and to make it look good. Our goal is to provide quality scissors.

Structure of the invention (means for solving problems) That is, as shown in the drawings of the embodiments described later, the invention includes a melody generating device 20 and an optical sensor 21 that controls the melody generating device 20. One of the scissors pieces 1 is provided with a light-receiving window 12 for introducing light into the optical sensor 21, and the other scissors piece 1 is provided with a shutter 5 that opens the light-receiving window 12 when the scissors are opened to a certain angle or more. It is something.

(Function) Then, when the scissors are opened more than a certain angle, the light receiving window 12
The shutter 5, which had been closing the
Light is irradiated onto the optical sensor 21 through 2. The melody generating device 20 generates a melody based on the light detection signal from the optical sensor 21.

(Example) An example embodying the present invention will be described below with reference to the drawings.

As shown in Figures 1 and 4, a pair of scissor pieces 1 are made of opaque plastic, and include a blade attachment part 2 and a grip ring 3.
It has A blade 4 having a circular base 5 is attached to the opposing inner surfaces of the two blade attachment parts 2.

Circular storage recesses 6 and 7 are formed on the outer surface of both the scissors pieces 1 between the blade attachment part 2 and the grip ring 3, and the central part of the bottom wall 8 of both the storage recesses 6 and 7 and the Insertion holes 9 and 10 are provided through the center of the base 5 of both blades 4, respectively. These insertion holes 9, 10 have opening/closing central shafts 1 as shown in FIG.
1 is inserted, and both scissors pieces 1 are supported by a concentric shaft 11 so as to be openable and closable.

A light receiving window 12 is transparently provided in the bottom wall 8 of the storage recess 6 in one scissors piece 1 and the base 5 of the blade 4, and the bottom wall 8 of the storage recess 7 in the other scissors piece 1 and the base of the blade 4 are transparent. 5 has an introduction hole 13 transparent therethrough. The light-receiving window 12 and the introduction hole 13 are formed at positions such that they overlap each other as shown in FIGS. 4a and 4b when both scissor pieces 1 are in the most open state as shown in FIG. Also, as shown in FIG. 1, when both scissors pieces 1 are closed, this light receiving window 12
The and introduction holes 13 do not overlap each other as shown in FIGS. 3a and 3b, and the light receiving window 12 is closed by the base 5 (shutter) of the blade 4. Note that the scissors are also closed when opened and closed during use.

As shown in FIG. 5, locking portions 14 are protruded at three locations on the inner circumference of both storage recesses 6 and 7, and locking portions 14 are provided at three locations on the inner and outer circumferences of the lids 15 and 16.
7 is provided protrudingly, and as shown in FIG. 3a, both locking parts 1
4 and 17 are engaged with each other, and both storage recesses 6 and 7 are closed by lids 15 and 16. One lid 1
5 is formed with an acoustic window 18 that communicates with the storage recess 6, and the other lid 16 is formed with an acoustic window 18 that communicates with the storage recess 7.
A lighting window 19 is formed which communicates with the.

A melody generator 2 is placed in the one storage recess 6.
0 and an optical sensor 21 are housed, and this optical sensor 21
is arranged corresponding to the light receiving window 12 on the bottom wall 8 thereof. This melody generator 20 has a power supply 20
a, a control circuit 20b, and a speaker 20c. When the light sensor 21 is irradiated with light, the light sensor 21 outputs a light detection signal to the control circuit 20b, and the control circuit 20b outputs a light detection signal to the speaker 20.
c, a melody is generated for a predetermined period of time.

Now, when the scissors constructed in this manner are closed as shown in FIG. 1, the light receiving window 12 and the introduction hole 13 are not overlapped with each other as described above. Therefore, as shown in Figure 3a, the lid 1
Light entering through the lighting window 19 of 6 reaches the storage recess 7, but is blocked by the base 5 (shutter) of the blade 4 and does not reach the optical sensor 21. Therefore, the melody generator 20 does not operate and no melody is produced.

On the other hand, when the scissors are in the most open state as shown in FIG. 2, the light receiving window 12 and the introduction hole 13 are in a superposed state with each other as described above. Therefore, as shown in FIG. 4a, light entering from the lighting window 19 of the lid 16 passes through the storage recess 7, the introduction hole 13 and the light receiving window 12, and is irradiated onto the optical sensor 21.
Therefore, the melody generating device 20 is activated and a melody is produced through the acoustic window 18 for a predetermined period of time.

Further, when the scissors are actually used to cut cloth or the like, the light does not reach the optical sensor 21 because the scissors are not opened to the point where the light receiving window 12 and the introduction hole 13 overlap. Therefore, the melody generator 20 does not operate and no melody is produced.

In this way, the scissors of this embodiment are designed to activate the melody generator 20 by the optical sensor 21 when the scissors are in the most open state, so when cutting cloth or the like, for example, the scissors can be opened as they are to the fullest extent. The user can easily turn on/off the melody generator 20 and have fun cutting the melody. In addition, since the optical sensor 21 is used as a means for turning on and off the melody generator 20, there are an acoustic window 18 and a lighting window 1 on the outside of the scissors.
Simply providing 9 has the effect of improving the appearance of the scissors.

In addition, in this embodiment, each component such as the power supply 20a and the optical sensor 2 constituting the melody generating device 20 is
1 may be stored together in one storage recess 6, or divided into both scissors pieces 1 and stored. Further, in this embodiment, the light receiving window 12 is provided on the bottom wall 8 of the storage recess 6 of one of the scissors pieces 1, and a shutter is provided on the base 5 of the blade 4 of the other scissors piece 1. In addition to being provided on the side wall of the recess 6, a shutter for opening and closing the light receiving window may be provided protruding from the outer wall of the storage recess 7 of the other scissors piece 1.

Effects of the invention In short, according to the invention, the melody generator 20 can be turned on and off by opening and closing operations, which are the original movements of scissors, so that when cutting, the user only has to open the scissors at a certain angle or more. The user can easily listen to the melody without feeling bothered, and has the effect of making the cutting process more varied and enjoyable. Furthermore, since the optical sensor 21 is used as a means for turning on and off the melody generating device 20, the appearance of the scissors is improved.
