Abstract

Question and answer apparatus includes switches 51-55, each for signifying entry into the apparatus of a chosen question, switches K1-K5 signifying respective answers, and multi-position switches V1-V5, each for presetting which of the answer switches signifies the correct answer (causing illumination of LED3) to a particular question. Operation of any of the other four answer switches will then cause illumination of wrong answer LED2. The questions and answers may be set out on cards which are positionable on the apparatus alongside push buttons for the question and answer switches. <IMAGE>

Description

THE QUESTION AND ANSWER PLAYER This invention relates to a question and answer player.

This question and answer player is an educational toy whereby questions can be answered by means of push-button switches. These player is for children to play with quest ions and answers.

According to the present invention there are five push-button switches on the question side and five push-released button switches on the answer side. At the rear, there is a power switch and five presenting sliding switches. The display to indicate that the question is fed into the player is by means of an indicator lamp which is call lightemitting diode. This is orange in colour. This diode is circular in shape. The display on the answer side consists of two similar lamps (all light-emitting diodes) They are circular in shape and glows with a red light for the wrong answer and glows with a green light for the right answer. There is no limit to the number of question to be answered by this player.Five questions are written on Artoard Paper and five answers are arranged randomly on another Artoard Paper. Once this set of questions are answered, another set of question can be preseted from the rear of the chassis and answered again.

A specific embodiment of the invention will now be described by example with reference to the accompany drawing in which: Figure 1 shows in three-dimension, the chassis of this player; its dimensions are a = 0.5 inches, b = 1.5 inches, c = 0.5 inches, d = 6 inches, e = 14 inches, f = 7 inches, g = 0.613 inches and h 2 10 inches.

(scale : 1 inch F 2.54 om) Figure 2 shows the back view of the chassis without the cover attached to it.

Figure 3 is the rear view of the chassis.

Figure 4 is the circuit diagram for the preset switches.

Figure 5 is the layout of the printed circuit board which is not to size.

Figure 6 is the electronic circuit diagram. D1, D2, D3, D4 and D5 are same value switching diodes. D6, D7, D8, D9 and D10 are another same value switching diodes. D11 and D12 are same value switching diodes.

S1, S2, S3, S4 and S5 are push-button switches, K1, K2, K3, K4 and K5 are push-released button switches. V1, V2, V3, V4, and V5 are sliding switches; each switch has five contacts. M5, R6, R7, R8 and R9 are identical resistors. R10, R3, R2, R4, Ell and R12 are resistors. T1 is a p-n-p silicon switching transistor. T2 is an n-p-n silicon switching transistor, E is a battery which is AA size. SP is a power witch. L.E.D.1, L.E.D.2 and L.E.D.3 are light emitting diodes.

Ther colour are orange, red and green respectively.

Figure 7 is the front view of the chassis. The two pieces of Artcard paper 13 are placed on it neatly. This is secured by means of pins 14 and punch holes 16 on the Artoard Paper.

Figure 8 and 9 show some illustrations on how questions are written and answers are arranged randomly. 15 is space for name or title of the type of questions and 17 is space for card number to be written on both the question card and its corresponding answer card. 18 illustrates the back of card A with the presetting numbers 19 written on it.

Referring to figure 6, when SP is switched on, current flows through question switches S1, S2, S3, 54 and S5. Since they are open-circuited, the whole circuitry is not connected to the battery. Pressing the answer switches K1, K2, K3, K4 and K5 will not make L.E.D.2 and L.E.D.3 to light up. This indicates that the question is not fed into the player.

When one of the question switch is pressed (e.g. S1), L.E.D.1 is lighted up. This indicates that one question is fed into the player. With S1 being switch on, the whole circuitry is connected to E (battery). Since V1, V2, V3, V4 and V5 are connected to the respective answer switches (K1, E2, K3, K4 and K5) when the answers are prested, one of the answer switch is connected to Sl via V1. Taking Kl to be connected to S1, and when it is pressed, the base of transistor T1 is not biased; it is open-circuited and L.E.D.2 (the indicator for the wrong answer) is not lighted. When K1 is pressed, the resistors R5 and R10 bias T2.

There is a potential increase across resistor R5 and R10 and the potential difference across R10 is higher than the potential difference across diodes dull and D12. Transistor T2 is forward biased and it is switched on. L.F.D.3 (the indicator for the right answer) is lighted.

Thuc K1 corresponds to the right answer. When K2 is pressed, resistor R4 is connected Vi2 diode D7 to R6 and R10, The potential difference across R10 is very much less then the potential difference across D11 and D12. T2 is reversed biased and L.E.D.3 will not be lighted.

However the potential difference cross R4 forward biased T1 and it is switched on. L.E.D.2 is lighted ups and the answer is incorrect.

Similar action takes place when K3, I and K5 are pressed one at a time Hence there are four wrong answern.

To answer another question, S1 needs to press again and it is opencircuited. L.E.D.1 is not lightes. Thus the previous question is erased fro this player. When another question switch is pressed, L.E.D.1 is lighted up again and this indicate that another question is fed into it.
