PROBLEM TO BE SOLVED: To provide an automatic voice regenerating device for vocalizing sutra which uses a solar battery as a sole power and an optical sensor and is high in weather-resisting force and durability in a tomb. SOLUTION: In an western tomb, a solar battery A is installed on the outer surface of a tombstone 1, a device storing cave 2 is provided at the bottom part of the tombstone 1, and an automatic voice regenerating device is installed inside it. Also, a through hole 20 is provided between the rear surface of the solar battery A and the device storing cave 2 and a lead wire is connected inside the tombstone 1, whereas leg parts 4 are formed at both lower ends of the tombstone 1 so as to provide a space part 5 between the leg parts and a pedestal stone 3 for use as a voice passage. In addition, a memory IC without any rotating part is used as a voice recording means. |
