Illustrate the use of the utility model Mental arithmetic machine below:

1) press on ﹠ off switch ON/OFF, loudspeaker send " collapsing ... " after the sound, Mental arithmetic machine is opened and is ready, and LCD plate LCD go up to show various state default values: pattern 1, progression 4, speed 4, score 000, music symbol.Can carry out various setting states this moment:

If a. click pattern key 5, then can become pattern 2 (promptly having become score recreation in limited time), and the timing demonstration occur, if, be illustrated in and see to beat how many branches in 60 seconds at this moment by numeral 6,0; Click pattern key 5 again, then can become pattern 3, Mental arithmetic machine is in the calculator function state, and at this moment progression, speed, score, timing, music symbol etc. by beginning key 9, just can work as calculator and use completely without demonstration at this moment.

If b. click progression key 6, then progression can become progression 5, again by then becoming

progression

6,7,8,9,0,1 successively, by that analogy.

If c. click speed key 7, then speed can become speed 5, again by then becoming

speed

6,7,8,9,0,1, by that analogy.

D. game state set appropriate after, by beginning key 9, after sending " pout, pout, pout " three, a formula appears on the LCD plate LCD immediately, as " 11 * 8=", if by numeral 8 twice (promptly 88), loudspeaker are said " OK " immediately, and score " 010 " appears on LCD plate LCD, second formula appears in " " pattern upset twice immediately on the LCD plate LCD.If this topic can not answered, can on the LCD plate LCD " 11 * 8=88 " can appear by answer key 8, pressed the answer key, this topic has not just been scored.

If e. pressed on ﹠ off switch ON/OFF, and pressed beginning key 9, then Mental arithmetic machine is played under default value.

2) if one formula certain hour occurred and can not return answer, also not by answer key 8, Mental arithmetic machine can send " too toot " chimes of doom, reports to the police 10 times, then gets back to armed state automatically, and heavily by beginning key 9, can carry out second board game this moment.

3) if after being ready 5 minutes also not by any key, Mental arithmetic machine is shutdown just automatically, afterwards if will use Mental arithmetic machine, then needs heavily press on ﹠ off switch ON/OFF.

4) if meet accident, as crash, LCD plate LCD show not congruent, can be by reset key REST, this moment, IC can inspect whole system, got back to armed state after inspecting.

5) if want to close or open sound, can be simultaneously by " 0 " and ". " two keys under armed state, during audible closure, music symbol does not show.

The utility model Mental arithmetic machine embodiment obtains when playing games (as 500 minutes) behind certain mark, and loudspeaker can be sung one section music, to encourage the player, also makes it to relax.After obtaining higher certain mark (as 1000 minutes), progression raises one-level automatically.
