Description

Technical Field

[0001] This application relates to the field of printing technology, and more particularly to a printer. Background Technology

[0002] To save space, some printers on the market have a paper storage mechanism mounted on the machine body in a rotatable manner. This paper storage mechanism can switch between two states by rotating: first, in an unfolded state, the paper storage mechanism is angled to the machine body and connected to the paper feed mechanism to ensure paper delivery; second, in a retracted state, the paper storage mechanism is completely housed in a storage slot on the side of the machine body, saving external space. Furthermore, the paper storage mechanism is connected to the machine body via clips to ensure a secure and stable hold in the retracted state.

[0003] To facilitate user operation, the outer surface of the paper storage mechanism has a notch for applying force with fingers to pull the paper storage mechanism out of the storage slot. However, the size of this notch is currently generally too small, making it relatively difficult to operate in practice; on the other hand, simply increasing the size of the notch would compromise the overall appearance and aesthetics of the printer.

[0020] In one embodiment, the storage slot includes a first storage section and a second storage section that are connected to each other, and the first storage section and the second storage section are respectively placed on adjacent sides of the body;

[0021] The paper storage mechanism includes:

[0022] A supporting component, the lower end of which is rotatably connected to the body, wherein in the retracted state, the supporting component covers the first retracted section; and in the unfolded state, the supporting component is positioned away from the first retracted section and inclined towards the body; and

[0023] A paper storage assembly, one end of which is rotatably connected to the upper end of the support member.

Simultaneously, by pressing, the locking component can be moved to disengage the second latching part from the first latching part, thereby releasing the lock and ensuring the paper storage mechanism can be switched to an unfolded state, tilted relative to the machine body and connected to the paper feeding mechanism. Because the pressing part is designed for finger operation, only a force sufficient to overcome the force of the first elastic component is needed to release the lock, making operation more effortless and convenient. It is worth noting that the size of the pressing part does not affect the required operating force; therefore, even with a miniaturized pressing part design, operational convenience is not reduced, thus contributing to maintaining the printer's overall simple, integrated, and aesthetically pleasing appearance.

[0044] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0045] See Figures 1-8 This invention illustrates a preferred embodiment of a printer, comprising a body 1, a paper storage mechanism 2, a locking component 3, and a first elastic component 4. The body 1 has a storage slot 11. The paper storage mechanism 2 is rotatably mounted on the body 1, and can switch between an unfolded state and a retracted state by rotation. In the unfolded state, the paper storage mechanism 2 is tilted relative to the body 1 to maintain communication with a paper feeding mechanism (not shown), allowing the paper feeding mechanism to deliver the set paper carried by the paper storage mechanism 2 to the printing mechanism, ensuring stable printing operation. In the retracted state, the paper storage mechanism 2 is stored in the storage slot 11, thus storing the paper storage mechanism 2 on the body 1, preventing the paper storage mechanism 2 from occupying external space, thereby reducing the overall size of the printer and facilitating storage and carrying. The device includes a first latching part 221; a locking component 3 is movably mounted on the body 1, the locking component 3 having a pressing part 31 and a second latching part 32, the pressing part 31 being used for pressing with a finger to drive the locking component 3 to move, the second latching part 32 being separable from and engaged with the first latching part 221; a first elastic component 4 is disposed between the locking component 3 and the body 1, the first elastic component 4 being used to provide the second latching part 32 with an elastic force to keep it engaged with the first latching part 221, so as to reliably store the paper storage mechanism 2 in the storage slot 11. When the paper storage mechanism 2 needs to be opened for printing, by applying a force to the pressing part 31 to overcome the elastic force, the locking component 3 can be driven to move to separate the second latching part 32 from the first latching part 221, thereby releasing the lock of the paper storage mechanism 2 and ensuring that the paper storage mechanism 2 can be switched to the unfolded state.

[0046] The printer of this invention, through the coordinated operation of the first latching part 221, the locking component 3, and the first elastic component 4, can both stably lock the paper storage mechanism 2 within the storage slot 11 of the machine body 1 and, by pressing, drive the locking component 3 to move it so that the second latching part 32 separates from the first latching part 221, thereby releasing the lock and ensuring that the paper storage mechanism 2 can switch to an unfolded state where it is tilted relative to the machine body 1 and remains connected to the paper feeding mechanism. Since the pressing part 31 is designed for finger operation, only a force sufficient to overcome the action of the first elastic component 4 needs to be applied to the pressing part 31 to release the lock, making operation more effortless and convenient. It is worth noting that the size of the pressing part 31 does not affect the required operating force; therefore, even if the pressing part 31 adopts a miniaturized design (smaller size), it will not reduce the ease of operation, thus helping to maintain the simplicity, integrity, and aesthetics of the printer's overall appearance.

[0047] In one embodiment, the first elastic component 4 is a spring, the first end of which is connected to the locking component 3, and the second end of which abuts against the body 1.

[0048] In one embodiment, the locking component 3 is provided with a first connecting post, and the first end of the spring is sleeved on the outside of the first connecting post to achieve a reliable connection between the spring and the locking component 3.

[0049] Of course, in other embodiments, the first elastic member 4 can also be a spring sheet structure.

[0050] See Figure 3 as well as Figure 8 In one embodiment, the second engaging portion 32 is provided with an inclined guide portion 33, which is configured such that when the paper storage mechanism 2 is switched to the storage state, it drives the locking component 3 to move through a sliding engagement with the paper storage mechanism 2, thereby engaging the first engaging portion 221 with the second engaging portion 32. Thus, during the process of switching the paper storage mechanism 2 to the storage state, the paper storage mechanism 2 pushes the locking component 3 to move through the sliding engagement with the inclined guide portion 33, thereby automatically engaging the first engaging portion 221 with the second engaging portion 32, making the locking operation effortless and convenient.

[0051] See Figure 3 In one embodiment, the first latching part 221 includes a latching groove, which can be detachably engaged with the second latching part 32 so that the first latching part 221 and the second latching part 32 are reliably connected together, thereby reliably locking the paper storage mechanism 2 in the storage slot 11.

[0052] Of course, in other embodiments, the second latching part 32 includes a latching groove that can be detached and engaged with the first latching part 221, which can also reliably lock the paper storage mechanism 2 into the storage slot 11.

[0053] See Figure 3 as well as Figure 4 In one embodiment, a guide mechanism 5 is provided between the locking component 3 and the machine body 1. The guide mechanism 5 is used to guide the locking component 3 to move more smoothly and stably, avoid jamming, and thus enable the paper storage mechanism 2 to switch states stably.

[0054] See Figure 3 as well as Figure 4 In one embodiment, guide mechanisms 5 are provided at both ends of the locking component 3 along its moving direction and between the locking component 3 and the body 1, so as to realize dual-point support for the locking component 3, thereby limiting the deflection and twisting of the locking component 3 during movement, ensuring that the locking component 3 can only move along a preset straight line, so that the locking component 3 moves more smoothly and steadily.

[0055] See Figure 3 as well as Figure 4 In one embodiment, the number of guide mechanisms 5 is three sets. Two sets of guide mechanisms 5 are placed on both sides of the pressing part 31 along the direction perpendicular to the movement direction to provide double-point support for the pressing part 31, preventing the pressing part 31 from tilting or jamming when pressed, and ensuring a smooth operating feel. The remaining set of guide mechanisms 5 is located between the second locking part 32 and the body 1 to ensure that the second locking part 32 can be aligned with the first locking part 221, thereby achieving reliable fastening and avoiding incomplete fastening due to misalignment. When unlocking, the guide mechanism 5 can ensure that the second locking part 32 smoothly disengages from the first locking part 221 along a predetermined trajectory without being interfered with by friction or minor deformation of other parts.

[0056] See Figures 3-4 as well as Figure 8 In one embodiment, the guide mechanism 5 includes:

[0057] Guide groove 51, guide groove 51 is provided on one of the body 1 and the locking component 3; and

[0058] The guide part 52 is disposed on the other side of the body 1 and the locking component 3. The guide part 52 is slidably engaged with the guide groove 51. That is, the locking component 3 can be moved and guided by the guide part 52 sliding in the guide groove 51. The structure is simple and easy to install. At the same time, the cost is low, which helps to reduce the overall cost of the printer.

[0059] Of course, in other embodiments, the guide mechanism 5 includes:

[0060] The guide rail is mounted on either the body 1 or the locking component 3; and

[0061] The slider is located on the other side of both the body 1 and the locking component 3. The slider is slidably connected to the guide rail. By moving the slider on the guide rail, the locking component 3 can also be moved and guided.

[0062] Of course, in other embodiments, the guide mechanism 5 includes:

[0063] Guide posts are provided on either the body 1 or the locking component 3; and

[0064] The guide sleeve is disposed on the other side of both the body 1 and the locking component 3. The guide sleeve is slidably sleeved on the guide post. By moving the guide sleeve on the guide post, the locking component 3 can also be moved and guided.

[0065] See Figure 2 as well as Figure 5 In one embodiment, the printer further includes:

[0066] The second elastic component 6 is movably disposed on the paper storage mechanism 2 and abuts against the body 1. The second elastic component 6 is used to drive at least a part of the paper storage mechanism 2 to remain outside the storage slot 11. Thus, after the locking of the paper storage mechanism 2 is released by pressing, the second elastic component 6 resets, thereby driving at least a part of the paper storage mechanism 2 out of the storage slot 11, that is, realizing the ejection of at least a part of the paper storage mechanism 2 from the storage slot 11, thereby facilitating the user to grab at least a part of the paper storage mechanism 2 and drive the paper storage mechanism 2 to switch to the unfolded state.

[0067] See Figure 2 as well as Figure 5 In one embodiment, the second elastic member 6 includes:

[0068] A retaining member 61 is movably disposed on the paper storage mechanism 2 and abuts against the machine body 1; and

[0069] An elastic element 62 is disposed between the paper storage mechanism 2 and the supporting element 61. The elastic element 62 is used to restrict the supporting element 61 to a state of contact with the machine body 1. That is, when the paper storage mechanism 2 is in the retracted state, the elastic element 62 shortens due to the contact between the supporting element 61 and the machine body 1, thereby allowing the paper storage mechanism 2 to be stored in the storage slot 11; when the paper storage mechanism 2 is in the unfolded state, the elastic element 62 resets and releases energy, driving the supporting element 61 to move, and using the reaction force of the machine body 1 on the supporting element 61 to push at least a part of the paper storage mechanism 2 out of the storage slot 11, making it convenient for the user to grasp and complete the unfolding action.

[0070] See Figure 5In one embodiment, the paper storage mechanism 2 has a first guide hole 222, which penetrates the side of the paper storage mechanism 2 that is face to face with the bottom wall of the receiving groove 11. The first guide hole 222 includes a first hole section and a second hole section that are connected to each other. The diameter of the first hole section is smaller than the diameter of the second hole section.

[0071] The abutment 61 is movably inserted into the first hole section. The abutment 61 is provided with a first limiting part 611. The first limiting part 611 is located in the second hole section. The outer diameter of the first limiting part 611 is larger than the hole diameter of the first hole section, so as to restrict the abutment 61 from disengaging from the paper storage mechanism 2.

[0072] The elastic element 62 is located in the second hole section. The elastic element 62 connects the first limiting part 611 and the paper storage mechanism 2, thereby realizing the reliable connection between the second elastic element 6 and the paper storage mechanism 2.

[0073] For ease of installation, one end of the elastic element 62 is fitted onto the second connecting post of the first limiting part 611, and the other end of the elastic element 62 abuts against the paper storage mechanism 2.

[0074] In one embodiment, the elastic element 62 may specifically be a spring or a sheet structure.

[0075] See Figures 1-2 In one embodiment, the storage slot 11 includes a first storage section 111 and a second storage section 112 that are connected to each other, and the first storage section 111 and the second storage section 112 are respectively placed on adjacent sides of the body 1.

[0076] Paper storage mechanism 2 includes:

[0077] Support member 21, the lower end of which is rotatably connected to the body 1; in the stowed state, support member 21 covers the first stowed section 111; in the unfolded state, support member 21 is moved away from the first stowed section 111 and tilted towards the body 1; and

[0078] The paper storage assembly 22 has one end rotatably connected to the upper end of the support member 21. In the retracted state, the paper storage assembly 22 covers the second storage section 112. In the unfolded state, the paper storage assembly 22 is supported by the support member 21, allowing it to tilt relative to the machine body 1 and maintain communication with the paper feeding mechanism. Since the first storage section 111 and the second storage section 112 are positioned on adjacent sides of the machine body 1, the support member 21 and the paper storage assembly 22 lie flat on adjacent sides of the machine body 1 in the retracted state, reducing the overall volume of the printer in the retracted state. Simultaneously, the support member 21, when unfolded, forms a stable tilted support structure with the machine body 1, providing reliable support for the paper storage assembly 22 and ensuring it remains tilted relative to the machine body 1. This allows the paper storage assembly 22 to maintain communication with the paper feeding mechanism, ensuring stable paper delivery to the printing mechanism.

[0079] Specifically, in one embodiment, the lower end of the support member 21 is provided with a first connecting shaft, which rotatably passes through the first connecting hole of the machine body 1, so that the support member 21 can rotate around the central axis of the first connecting shaft; similarly, one end of the paper storage assembly 22 is provided with a second connecting shaft, which rotatably passes through the second connecting hole at the upper end of the support member 21, so that the paper storage assembly 22 can rotate around the central axis of the second connecting shaft.

[0080] It is understood that the paper storage assembly 22, the paper feeding mechanism, and the rest of the printer structure are all prior art. For details, please refer to existing literature or the applicant's previous patent applications, and will not be elaborated here.

[0081] See Figures 6-7 In one embodiment, the body 1 has an inspection port 12;

[0082] The printer also includes:

[0083] Inspection door 7 is rotatably connected to the body 1. Inspection door 7 can close or open the inspection port 12.

[0084] Magnetic component 8 is disposed on either the inspection door 7 or the body 1.

[0085] A magnetic guide 9 is disposed on the other of the inspection door 7 and the body 1. The magnetic guide 9 and the magnetic element 8 are magnetically attracted to each other to restrict the inspection door 7 to a closed inspection port 12 state.

[0086] The unlocking component 10 is slidably mounted on the body 1. The first end of the unlocking component 10 is located in the storage slot 11. The first end of the unlocking component 10 is covered by the paper storage mechanism 2 in the storage state, thereby hiding the first end of the unlocking component 10 inside the body 1. The second end of the unlocking component 10 can enter and exit the maintenance port 12. The second end of the unlocking component 10 is covered by the maintenance door 7 in the closed maintenance port 12, thereby hiding the second end of the unlocking component 10 inside the body 1. When the second end of the unlocking component 10 enters the maintenance port 12, the unlocking component 10 abuts against the maintenance door 7 to drive the magnetic component 8 to disengage from the magnetic conductor 9. Thus, after the paper storage mechanism 2 is pulled out of the storage slot 11, the first end of the unlocking component 10 can be exposed, making it convenient for the user to push the unlocking component 10 to abut against the access door 7, thereby causing the magnetic component 8 to disengage from the magnetic guide component 9, thus opening the access door 7. This facilitates the maintenance of the printer's internal structure or the replacement of ink cartridges located inside the printer. During the closing of the access door 7, the contact between the access door 7 and the unlocking component 10 pushes the second end of the unlocking component 10 out of the access port 12, causing the magnetic component 8 and the magnetic guide component 9 to magnetically engage, thereby reliably confining the access door 7 to the closed access port 12.

[0087] See Figure 7 In one embodiment, the body 1 has a second guide hole 13. The first end of the second guide hole 13 is connected to the storage slot 11, and the second end of the second guide hole 13 is connected to the inspection port 12. The unlocking component 10 is slidably inserted through the second guide hole 13, and the first end of the unlocking component 10 extends into the storage slot 11 through the first end of the second guide hole 13, while the second end of the unlocking component 10 enters and exits the inspection port 12 through the second end of the second guide hole 13. In this way, the movement path of the unlocking component 10 is restricted by the second guide hole 13, ensuring that the unlocking component 10 moves more smoothly and stably, avoiding jamming, thereby improving the operating feel.

[0088] See Figure 7 In one embodiment, the second guide hole 13 includes a first guide section, a second guide section and a third guide section connected in sequence. The first guide section is connected to the receiving groove 11, the third guide section is connected to the inspection port 12, and the inner diameter of the second guide section is larger than the inner diameters of the first guide section and the third guide section.

[0089] The unlocking component 10 is provided with a second limiting part 101, which is movably disposed in the second guide section. The outer diameter of the second limiting part 101 is larger than the inner diameter of the first guide section and the third guide section to prevent the unlocking component 10 from disengaging from the second guide hole 13.

[0090] In one embodiment, the magnetic element 8 may specifically be a magnet, while the magnetically conductive element 9 may specifically be an iron element.

[0091] Of course, in other embodiments, the magnetic element 8 can be a rubber magnetic strip, and the magnetic conductive element 9 can be a silicon steel sheet.

[0092] Of course, in other embodiments, both the magnetic element 8 and the magnetic conductor 9 can be permanent magnets. In this case, the magnetic element 8 and the magnetic conductor 9 are installed with opposite poles facing each other.
