PURPOSE:To make the life of a device longer, by using a solid element as a memory unit and by constituting the information to be read out only electronically. CONSTITUTION:The memory unit consists of solidstate elements, and it is provided with the memory unit 4 of removable free and memory units 15, 16 assembled in the unit main body in advance. For example, some units 4 are prepared in response to the location of burgain sale and the units 4 and replaced in response to the change in the burgain sale corner, allowing the audio in matching with the object. In this case, the part changing the content only is changed by the application of the units 4. With the constitution like this, since digital data can be read out electronically only from the solidstate elements, the life is remarkably extended. |
