FIG. 5 is a configuration perspective view of one embodiment of the present invention. 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 05-05-2019 1 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 と と と と と と 光電 光電 光電 光電 光電 光電 光電 光電 光電 光電 光電 光電 光電 光電 光電 光 電 1 Between the mask and the light source, a slit is provided which identifies and has two or 05-05-2019 2 more slits provided in the mask and which can change the amount of light passing through the slit and reaching the photoelectric conversion device. What is claimed is: 1. A mechanicalelectrical conversion device comprising: a shutter to which vibration of a d-resonance frequency is transmitted from a mechanical vibration body.
