Description

[Detailed Description of the Invention] [Industrial application field and outline of the invention] The present invention relates to a microcomputer-controlled instrument incorporating a voice guidance device, which eliminates the need for voice guidance when used to operate the instrument. When this happens, it is possible to record a message or the like in the voice memory in which the voice guidance was written, thereby effectively using the voice memory.

[Prior art and its problems] With the recent microcomputer-controlled type appliances such as rice cookers and microwave ovens, the operation of the appliances has become complicated due to the expansion of their functions, and operation procedures such as timer setting and temperature setting operations have been announced. The ones that I tried to guide in became popular.

In this case, a guidance message indicating the procedure of instrument operation is written in the ROM incorporated in the microcomputer (hereinafter, abbreviated as microcomputer) in the instrument, and when the voice reproduction switch is turned on before the instrument operation, , RO above
The guidance message in M is output from the speaker connected to this.

For this reason, the above-mentioned type of device that outputs a voice message has an advantage that the device can be easily operated without reading an intricate instruction manual.

However, in the above-mentioned conventional one, even if the operation instruction message is not needed because the operation procedure of the instrument is memorized, the message is left as it is stored in the ROM as the voice memory. There was a problem that was completely wasted.

[Technical problem] The present invention has been made in view of the above point, and includes "a voice memory storing a voice message for explaining instrument operation,
Effective use of the voice memory in which unnecessary guidance messages are stored in a "microcomputer-controlled device equipped with a speaker for reproducing the contents of the voice memory and a voice reproduction switch operated during the reproduction". Therefore, it is a technical subject to enable voice recording such as a message in the voice memory.

[Means] A technical means of the present invention for solving the above-mentioned problem is "a microphone which adopts a specific RAM in a RAM group constituting a microcomputer as a voice memory and inputs voice data such as a message to the voice memory. (M), a recording switch that is turned on when the voice data is input, and the RAM
A battery (47) was provided to back up only the RAM for voice memory in the group. '

[Operation] The above technical means operates as follows.

The voice message for operating the device is stored in a specific RAM in the RAM group at the time of manufacturing the device, and the specific RAM is backed up by the battery (47).

Therefore, during product distribution until the manufactured device reaches the end of the consumer, the specific RAM is backed up by the battery (47) and the voice message is not lost.

Next, if the purchaser uses the device before he or she becomes proficient in operating the device, if the voice playback switch is turned on prior to using the device, it is recorded in advance in the voice memory as in the conventional device described above. The instrument operation message is output from the voice speaker, and the instrument can be operated by the procedure according to the message.

Now, if you want to record a message or the like in the voice memory when you forget the operation procedure of the equipment and do not need the operation message, turn on the recording switch to turn on the voice memory and the microphone (M). ) Is connected, and a message (voice data) such as a message is input from the microphone (M) in this state. Then, the input data is written in the voice memory composed of the RAM, and stored and held in the memory.

Next, when playing back the message or the like written in the voice memory, it is sufficient to turn on the voice reproduction switch, take out the message or the like written in the voice memory from the speaker and listen to it.

As described above, according to the above-mentioned technical means of the present invention, a message or the like can be recorded in the voice memory in which the unnecessary operation guidance message is written.

[Effect] Since a message or the like can be recorded in the voice memory for explaining the operation of the instrument, which is no longer needed after being familiar with the operation of the instrument, it is possible to effectively use the unnecessary voice memory.

Only the specific RAM selected from the RAM group for voice memory is backed up by the battery (47), so the power consumption for backup is less than that of the one in which the entire RAM group is backed up at once. Therefore, there is an advantage that a small capacity battery can be used even if the product distribution route from the manufacturing of the device to the delivery to the consumer is long.

[Embodiment] Next, an embodiment of the present invention described above will be described in detail with reference to the drawings.
