[0019] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1-5 As shown, this embodiment provides a printer with a key hot key sheet that can be quickly replaced, including a printer body 10, a key protection sheet 20, a key circuit board 30 arranged on the printer body 10, a key hot key sheet 40 that can be quickly replaced and a controller located between the key protection sheet 20 and the key circuit board 30. The function keys corresponding to the content that needs to be printed and is used frequently are usually called hot keys.

[0022] The key protection sheet 20 includes a connecting portion 21, and the connecting portion 21 is used to connect with the printer body 10. In this embodiment, the connecting portion 21 is located at the upper portion of the key protection sheet 20, and the key protection sheet 20 is connected to the upper end surface of the printer body 10. In other embodiments, the connecting portion 21 can also be located at the left side or right side of the key protection sheet 20, so as to connect the key protection sheet 20 to the upper end surface of the printer body 10 or other surfaces suitable for key pressing.

[0023] The connection part 21 may be adhered to the printer body 10 by glue. For example, the connection part 21 may be adhered to the printer body 10 by viscous glue. In other embodiments, the connection part 21 may be integrally formed with the printer body 10.

[0024] The key protection sheet 20 also includes a pressing portion 22, and the pressing portion 22 corresponds to the key hot key sheet 40. The key protection sheet 20 is made of a transparent material. Alternatively, the key protection sheet 20 can also be made of a translucent material. Alternatively, at least the pressing portion 22 of the key protection sheet 20 is made of a transparent or translucent material. In this way, the characters of the key hot key sheet 40 under the key protection sheet 20 can be clearly seen, so that the user can clearly see the corresponding common content that needs to be printed on the key hot key sheet during the use of the printer, and the corresponding content can be printed by pressing the corresponding key area position on the hot key sheet.

[0025] The key hot key sheet 40 is closely attached to the key circuit board 30. The hot key position on the key hot key sheet 40 corresponds to the key point position on the key circuit board 30. In this way, when the hot key position on the key hot key sheet 40 is pressed, the pressing force is transmitted to the key point position on the key circuit board 30, so that the signal at the key point position is triggered. The corresponding relationship between the hot key on the key hot key sheet 40 and the key point on the key circuit board 30 has been set in advance on the controller of the printer. Therefore, when the signal at the key point position is triggered, the character information represented on the corresponding hot key is quickly printed out by the printer, so that the content to be printed on the hot key sheet can be executed by just pressing the key, and printing is quick and convenient.

[0026] The controller may be a control device disposed inside the printer, or may be a device disposed outside the printer and connected to the printer, such as a computer.

[0027] The key hot key sheet 40 is replaceable. After replacing a new key hot key sheet 40, it is only necessary to set the corresponding relationship between the hot keys on the key hot key sheet 40 and the key points on the key circuit board 30 in the controller to switch to the new printing content; therefore, the key hot key sheet can be quickly replaced, and different key hot key sheets 40 can be replaced in different environments to print different contents, thereby meeting the various usage purposes of customers, having a wide range of applications, and greatly expanding the functions of the printer.

[0028] The printer proposed in this embodiment can quickly replace the key hot key sheet to control the printing of some frequently used content that needs to be printed. The specific operation process of the printer in this embodiment is as follows: when it is necessary to replace a key hot key sheet 40 of a certain group of new functions, first open the key protection sheet 20, take out the existing key hot key sheet 40, and then put the new key hot key sheet 40 into the corresponding position and release the key protection sheet 20, so that the key protection sheet 20 presses the key hot key sheet 40 tightly against the key circuit board 30, so as to realize the rapid replacement of the key hot key sheet 40. At the same time, the corresponding computer control end sets the corresponding relationship between the hot key on the new key hot key sheet 40 and the position of the key point on the key circuit board 30. After the setting is completed, when it is necessary to execute the printing of the content information on the key hot key sheet 40 later, it is only necessary to press the button to execute the content that needs to be printed on the hot key sheet.

[0029] Preferably, a marker is provided on the key hot key sheet 40, and the marker records the information of the key hot key sheet 40, such as the serial number of the key hot key sheet 40 or the hot key information of the key hot key sheet 40; the marker may be a radio frequency chip or an NFC tag, etc. A decoder is provided on the key circuit board 30, and the decoder can read the information on the marker to obtain the information of the current key hot key sheet 40. The decoder is connected to the controller of the printer, and the controller can automatically set the corresponding relationship between the hot key on the current key hot key sheet 40 and the position of the key point on the key circuit board 30 according to the information of the current key hot key sheet 40, so as to achieve further automation and further improve the convenience of use.
