[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-10 A learning card machine with replaceable reading cards includes a housing 1, a card area 101 on the housing 1, and learning cards 2 replaceably disposed on the card area 101.

[0022] The casing 1 also includes a control unit 3, a card arrival detection unit 4, an information storage device 5, an information playback device 6, and a key matrix carbon film 7. The card arrival detection unit 4, the information storage device 5, the information playback device 6, and the key matrix carbon film 7 are all electrically connected to the control unit 3 (electrical signal transmission connection).

[0023] The card placement detection unit 4 is used to detect whether the learning card 2 is located in the card area 101, and is configured to provide a card placement signal to the control unit 3 when the learning card 2 is detected to be located in the card area 101.

[0024] The carbon film key matrix 7 includes a card function selection key area 701 and a card information description key area 702.

[0025] After the learning card 2 is installed or replaced, the control unit 3 can confirm that the learning card 2 is located in the card area 101 through the card positioning detection unit 4, that is, the card positioning detection unit 4 provides the control unit 3 with a card positioning signal.

[0026] Users can select card functions by pressing the corresponding keys in the key area 701. For example, if the selected card function is a Chinese initial consonant reading card, a Chinese final vowel reading card, or an initial consonant and final vowel reading card, the information storage 5 will pre-record the corresponding card function information. Card functions can be selected by pressing a single key in the key area 701, or by pressing the same and / or different keys in the key area 701 to form a key press combination. The information storage 5 will pre-record the matching data between the key signals and the card functions.

[0027] That is, by pressing the corresponding key in the card function selection key area 701, the corresponding card function press selection signal is input to the control unit 3, and the control unit 3 confirms the selected card function according to the card function press selection signal.

[0028] After the corresponding key in the card information description key area 702 is pressed, the control unit 3 retrieves the learning information corresponding to the card information description key selection signal from the information memory 5 according to the received corresponding card information description key selection signal, and plays the learning information through the information playback device 6.

[0029] For example, after the Chinese initial consonant reading cards (learning cards) are installed on the card area 101 and the card placement detection unit 4 confirms that the learning cards are in place, like Figure 6 , 7 As shown, the carbon film of the key matrix is ​​connected to the I / O of the chip U1 of the control unit (pins PB01-PB11, PA0-PA7). When any key is pressed, the corresponding voltage change will be detected to calculate and confirm the pressed carbon film key.

[0030] Tap the card to select the "Chinese Initials" key in key area 701 (this can be done by the user pressing their finger on the corresponding position on the learning card, causing downward pressure on the corresponding part of the learning card to trigger the "Chinese Initials" key); for example... Figure 5 The key shown is 7011, and refer to... Figure 3When the button matrix carbon film shown is pressed, the carbon film point 7011a of the first layer of the button matrix carbon film makes contact and conduction with the carbon film point 7011b of the second layer of the button matrix carbon film. The control unit calculates the voltage fed back from the button matrix carbon film and identifies the pressed key position as the "Chinese initials" key position 7011.

[0031] The control unit confirms that the selected card function is: Chinese initial consonant reading card.

[0032] The card information describes that key area 702 has multiple keys that correspond one-to-one with the initial consonant symbols on the Chinese initial consonant reading card above.

[0033] When you press the key in the card information description key area 702 that corresponds to the initial consonant symbol "b" on the Chinese initial consonant reading card above; such as Figure 5 When the key 7021 shown is pressed, the carbon film point 7021a of the first layer of the carbon film of the key matrix makes contact and conduction with the carbon film point 7021b of the second layer of the carbon film of the key matrix. The control unit calculates the voltage fed back from the carbon film of the key matrix and identifies the pressed key as key 7021.

[0034] The control unit retrieves the learning information (initial identifier "b") corresponding to the card information description and the selected signal (i.e., the key trigger signal of key 7021) from the information memory 5 according to the received card information description and the selected signal, and plays the learning information (initial identifier "b") through the information playback device 6.

[0035] For example, the initial consonant "b" can be played through the following speaker.

[0036] In some embodiments, the information playback device 6 includes a speaker.

[0037] In some embodiments, the housing 1 includes a bottom shell 102 and a front shell 103, with the front shell 103 covering the bottom shell 102, such that an installation space is formed between the front shell 103 and the bottom shell 102, which is the internal installation space of the housing.

[0038] Some components can be installed within the installation space, such as the aforementioned information storage device, information playback device, and control unit.

[0039] In some embodiments, the card area 101 is located on the faceplate 103.

[0040] In some embodiments, a portion of the top of the faceplate 103 is recessed downward to form a receiving groove 104.

[0041] The side wall of the receiving groove 104 has an insertion hole 105 that communicates with the mounting space inside the face shell 103. The learning card 2 has a card body 201 corresponding to the receiving groove 104 and an insertion identification part 202 that is inserted into the face shell through the insertion hole.

[0042] The card placement detection unit 4 is installed inside the face shell 103 and is configured to perform placement detection on the insertion identification part 202.

[0043] In some embodiments, the learning cards are typically paper cards or flexible plastic cards.

[0044] In some embodiments, the card placement detection unit 4 includes a micro switch disposed within the faceplate 103.

[0045] In some embodiments, when the insertion identification part 202 of the learning card is inserted into the shell 103 from the insertion hole 105, the insertion identification part 202 causes the contact of the micro switch to be pressed and triggered.

[0046] In some embodiments, the key-position portions of the key matrix carbon film 7 are located on the bottom wall of the receiving groove 104. After the learning card is installed, the card body is positioned above the key matrix carbon film.

[0047] The side wall of the receiving groove 104 is provided with a carbon film mounting hole 106 that communicates with the mounting space inside the shell 103.

[0048] The gold fingers 703 of the button matrix carbon film 7 are inserted into the installation space through the carbon film mounting hole 106. The gold fingers 703 of the button matrix carbon film and the circuit pins of the motherboard with control unit 3 are made in contact by pressing, and are pressed tightly by the pressure strip 11 and screws to ensure good contact.

[0049] In some embodiments, the control unit 3 is provided with a card function selection program module, a card information reading program module, and a connection switching program module.

[0050] The key layout of the card function selection key area 701 and the key layout of the card information description key area 702 have at least partial overlap.

[0051] After the control unit 3 confirms that the learning card 2 is located in the card area 101 by the card positioning detection unit 4, the control unit 3 switches to the card function selection program module corresponding to the card function selection key area of ​​the key matrix carbon film by switching the connection program module.

[0052] That is, after receiving the card arrival signal, the control unit 3 switches the connection program module to connect the card function selection key area of ​​the key matrix carbon film through the card function selection program module.

[0053] The control unit 3 confirms the selected card function through the card function selection program module based on the card function click selection signal.

[0054] After confirming the selected card function, the control unit 3 switches the connection program module to connect the card information description key area of ​​the key matrix carbon film through the card information reading program module.

[0055] The switching connection program module is configured as follows: after the control unit 3 receives the card arrival signal, the control unit 3 switches to connect with the card function selection key area of ​​the key matrix carbon film through the card function selection program module; after the control unit 3 confirms the selected card function (or after the control unit receives the card function click selection signal), the control unit 3 switches to connect with the card information description key area of ​​the key matrix carbon film through the card information reading program module.

[0056] In this way, the keys in the card function selection key area and the key area in the card information description key area can be reused, effectively reducing the hardware configuration.

[0057] In some embodiments, a power supply unit 8 is also provided on the housing 1.
