DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for
converting mechanical vibrations into electrical vibrations. Furthermore, the present invention
relates to an apparatus for converting mechanical vibration into electrical vibration by means of
a photoelectric conversion device. An object of the present invention is to obtain a device that
converts mechanical vibration into electrical vibration with high sensitivity. 2 Therefore,
according to the present invention, an electrical signal having a large change layer can be
obtained. The invention also provides a device with very low mechanical load. The present
invention also provides a mechanical-electrical conversion device which has a very small
mechanical load and is suitable as a pickup for a 30 code player. A mechanical-electrical
conversion device using a conventional photoelectric conversion device is configured as shown in
FIG. , Photoelectric conversion devices 3 provided with a mask 2 on the front face so as not to
receive external light disturbances other than the light w1 and the light source 1, mechanical
vibrators (not shown) between the two The non-light-transmitting shutter 4 to which the
vibration is transmitted is provided, and the amount of light reaching the photoelectric
conversion device 3 is changed by the shutter 4 to convert the vibration of the mechanical

vibrating body into the electric vibration. However, in this conventional device, the entire surface
of the photoelectric conversion device i is used and the output signal voltage is large, but the
amount of change is small. That is, a large amount of direct current is included. The present
invention has the following configuration in order to obtain a large variation electrical signal. As
shown in FIG. 2, a photoelectric conversion device 12y is provided in which a light source 1 of an
incandescent lamp and a photoelectric conversion surface are opposed to the light source. A
fixed mask 14 is provided which has a plurality of slits 13 between the above and which does not
change the relative position of the light source 11 and the photoelectric conversion device 12. A
plurality of slits 13 of the mask 14 are simultaneously opened and closed on the movable shutter
15 where the vibration of the mechanical oscillator is further transmitted between the light
source 11 and the photoelectric conversion device 12 and passes through the slits 13 to reach
the photoelectric conversion surface. A slit 16 capable of changing the amount of light is
provided. According to the present invention, the light beam from the light source 11υ is
controlled by the slits 13 and 16 to reach the photoelectric conversion device 12, and a plurality
of slits 13 are provided. Although the amount of light reaching the photoelectric conversion
device 2 is reduced by the lattice portion 17 for forming the slits 13 of the fixed mask 14, the
cooperation of the slits 13 and 16 significantly changes the amount of light. Become fat. 3 uses
the small pilot Lang as light source 1 and the solar cell as photoelectric conversion device 3 in
the structure of FIG. It is an output voltage characteristic of the solar cell with respect to the
displacement of the shutter 4 when it is moved.
At this time, solar cells and pilot lamps are 3! A load resistance of 30 Ω is connected to the solar
power EndPage: 1 pond at a distance of 1 rIIL. As it is clear from this curve, the shutter is o, IJ.
When displaced, an output voltage of up to 124 rnV is obtained. However, according to the
present invention, a custom order as shown in FIG. 4 is obtained. Again, pilot lamps, solar cells
are used, the stationary mask is fixed on the solar cell and the movable shutter moves relative to
the stationary mask. The solar cell and the pilot lamp are arranged at a distance of 57 m, and the
load resistance of 30 Ω is connected to the solar cell. As is apparent from this curve, when the
shutter changes o, x ', an' pressure is obtained at an output of up to 288 mV. Thus, according to
the present invention, an output voltage with a large amount of change can be obtained. FIG. 5
shows a cross-sectional view when the above-mentioned apparatus of the present invention is
used for a pickup of a record player, and has a light source 31 of a pilot wrap, a shutter 32
having a slit similar to that of FIG. The fixed mask 33 and the photoelectric conversion device
[111111] 34 are disposed inside the pickup cartridge 35, and a needle 36 for tracing the sound
groove of the record is provided below the shutter 32. Accordingly, the vibration of the needle
36 due to the sound groove is given to the shutter '32 and an electric signal is obtained by the
photoelectric conversion device. At this time, the mechanical load of the needle 36 is only the
shutter 32, and a pickup with very light needle pressure can be obtained. 轢 範 囲 範 囲 1 1 1 と
