[0078] The technical solutions in the embodiments (or, modes of implementation) of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.
[0079] If the present application has involved the terms of directionality or position relationship (for example, up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture (as shown in the drawings); if the specific posture changes, the directionality or position relationship also changes accordingly. In addition, the terms "first", "second", etc. in the embodiments of the present application are only used for convenience of description, and cannot be understood as indicating or implying relative importance.
[0080] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. The features in the following embodiments can be combined with each other without conflict.
[0081] As shown in Figure 1 The present application discloses a printer 1, which comprises a printing main body 10 and a paper box 20. The paper box 20 cooperates with the printing main body 10, specifically, the paper box 20 is detachably mounted on the printing main body 10. The paper box 20 carries paper for printing. In the normal use process, the paper box 20 and the printing main body 10 are fixedly connected, and the paper will enter the printing main body 10 from the paper box 20 along the paper movement direction M. The paper box 20 comprises a mounting end 21 and a tail end 22 which are oppositely arranged along the paper movement direction M, and the mounting end 21 is detachably connected to the printing main body 10. In the present application, the printer 1 in the present application is a printer 1 for printing photos. Some printers 1 need the paper to enter the printing main body 10 multiple times to complete color printing. For example, some printers 1 need to first let the paper enter the printing main body 10 to complete the printing work of the first color. After the printing work of the first color is completed, the paper is withdrawn from the printing main body 10 to the paper box 20 along the paper movement direction M, and then the paper is again allowed to enter the printing main body 10 to complete the printing work of the second color. After the printing work of the second color is completed, the paper is withdrawn from the printing main body 10 to the paper box 20 along the paper movement direction M. This is repeated until the printing work is completed. Of course, in another part of the printer 1, the paper only needs to enter the printing main body 10 from the paper box 20 along the paper movement direction M once to complete the printing work of the photo.
[0082] It should be noted that the printer 1 in the present application is a printer 1 for printing photos, and of course, in other embodiments, the printer 1 can also be a printer 1 for printing ordinary paper.
[0083] In combination Figures 2-5 As shown in the drawings, in the present embodiment, the paper box 20 comprises a mounting shell 100, a blocking piece 200 and a cover 300.
[0084] The mounting shell 100 comprises a bottom plate 110 and a side plate 120, and the bottom plate 110 and the side plate 120 enclose a carrying space 130 for carrying paper. The cover 300 is coupled to the mounting shell 100, and forms a relatively closed space to protect the paper in the paper box 20. The blocking piece 200 is rotatably connected to the bottom plate 110 of the mounting shell 100. The blocking piece 200 is used to rotate between a storage position 201 and an unfolded position 202.
[0085] When the blocking piece 200 is in the storage position 201, at least part of the blocking piece 200 cooperates with the bottom plate 110 as a wall of the carrying space 130 for accommodating paper. Of course, in other embodiments, the blocking piece 200 can be away from the carrying space 130 when the blocking piece 200 is in the storage position 201.
[0086] When the blocking piece 200 is in the unfolded position 202, at least part of the blocking piece 200 is located in the carrying space 130 and divides the carrying space 130 into a first space 131 and a second space 132. The second space 132 is closer to an end of the paper box 20 (i.e., the mounting end 21) for cooperating with the printing body 10 than the first space 131, and the second space 132 is used to accommodate paper.
[0087] In the present embodiment, the printer 1 can print two different sizes of photos, i.e., the paper box 20 can be used to carry two different sizes of paper. When the paper of a larger size (hereinafter referred to as "paper of a first size") is needed, the blocking piece 200 is switched to the storage position 201, and the carrying space 130 is used as a whole to accommodate the paper of the first size. When the paper of a smaller size (hereinafter referred to as "paper of a second size") is needed, the blocking piece 200 is switched to the unfolded position 202, and the second space 132 in the carrying space 130 is used to accommodate the paper of the second size.
[0088] Therefore, when the size of the paper carried in the paper box 20 needs to be changed, the position of the blocking piece 200 can be changed to form a space matching the size of the paper. In the above arrangement, by providing a movable blocking piece 200 in one paper box 20, the paper box 20 can be used to carry paper of different sizes, which is convenient to operate. At the same time, different paper boxes 20 do not need to be provided for paper of different sizes, which is low in cost.
[0089] It should be noted that in the present embodiment, only one blocking piece 200 is provided in the paper box 20. Of course, in other embodiments, one paper box 20 can contain multiple blocking pieces 200 to divide the carrying space 130 differently, so that one paper box 20 can match more sizes of paper.
[0090] In combination Figures 2-6 As shown, the blocking piece 200 includes a baffle 210 and a limiting plate 220. The limiting plate 220 is fixedly connected to one end of the baffle 210. When the blocking piece 200 is located at the unfolded position 202, the baffle 210 is located in the carrying space 130. The bottom plate 110 is recessed in a direction away from the carrying space 130 to form an accommodating cavity 140, and when the blocking piece 200 is located at the unfolded position 202, the baffle 210 is located in the accommodating cavity 140. The limiting plate 220 is always away from the carrying space 130.
[0091] In the above arrangement, when the blocking piece 200 is located at the unfolded position 202, the baffle 210 enters the carrying space 130 and spatially cuts and divides the carrying space 130. When the blocking piece 200 is located at the storage position 201, the baffle 210 enters the accommodating cavity 140 to avoid the baffle 210 interfering with the movement of the first size of paper located in the carrying space 130.
[0092] Specifically, when the blocking piece 200 is located at the storage position 201, the surface of the baffle 210 facing the carrying space 130 serves as a first surface 211. When the blocking piece 200 is located at the storage position 201, the first surface 211 is parallel to the surface of the bottom plate 110 facing the carrying space 130. In the present embodiment, the first surface 211 coincides with the surface of the bottom plate 110 facing the carrying space 130, so that the lower surface of the carrying space 130 is flat. Of course, in other embodiments, it is only necessary to ensure that the first surface 211 is away from the carrying space 130 compared to the surface of the bottom plate 110 facing the carrying space 130, so as to avoid the baffle 210 interfering with the movement of the first size of paper located in the carrying space 130.
[0093] Further, as shown in Figure 7 and Figure 8 In the present embodiment, an abutting plate 141 is provided in the accommodating cavity 140, and when the blocking piece 200 is located at the storage position 201, the baffle 210 abuts against the abutting plate 141. By providing the abutting plate 141, the position stability of the blocking piece 200 at the storage position 201 is limited.
[0094] In combination Figures 7-14 As shown, if necessary, reference is made to Figure 6As shown, a limiting hole 150 is provided on the base plate 110. In this application, the limiting hole 150 is formed in the receiving cavity 140, and the area without the limiting hole 150 is used as the aforementioned limiting plate 220.
[0095] The sidewall of the limiting hole 150 extends toward the center of the limiting hole 150 to form a rotating protrusion 160. A rotating shaft 230 is provided on the blocking member 200, and the rotating shaft 230 is rotatably mounted on the rotating protrusion 160. In this embodiment, the rotating shaft 230 is located at the connection position between the baffle 210 and the limiting plate 220. Through the above arrangement, a rotating connection between the baffle 210 and the base plate 110 is achieved.
[0096] The rotating protrusion 160 has an opening 161 for the rotating shaft 230 to enter and exit. The cardboard box 20 also includes a bottom shell 400, which is detachably connected to the side of the mounting shell 100 away from the bearing space 130, and together with the mounting shell 100, forms a receiving space 410. The bottom shell 400 includes a positioning plate 420, which blocks the opening 161 to prevent the rotating shaft 230, which mates with the rotating protrusion 160, from falling out of the opening 161.
[0097] Combination Figures 1-10 As shown in this application, when it is necessary to fix the blocking member 200 to the mounting shell 100, the blocking member 200 is first placed in the mounting shell 100 to fix the bottom shell 400. Then, the blocking member 200 is moved towards the bearing space 130. The component structure of the blocking member 200 enters through the limiting hole 150, and the rotating shaft 230 enters the rotating protrusion 160 through the opening 161. Finally, the bottom shell 400 and the mounting shell 100 are fixedly connected. At this time, the positioning plate 420 abuts against the lower end of the bottom shell 400 and seals the opening 161 to prevent the rotating shaft 230 from falling off, thereby realizing the fixed connection between the blocking member 200 and the mounting shell 100.
[0098] In this embodiment, after the blocking member 200 is installed in place, the user can directly pry it open to retract the blocking member 200 from its storage position 201 (see reference). Figures 7-10 Switch to expanded position 202 (reference) Figures 8-14 Alternatively, it can switch from the unfolded position 202 to the folded position 201. For ease of user operation, the baffle 210 of the blocking member 200 has a corresponding recess as a handle position 240. Of course, in other embodiments, automated operation can also be achieved by adding a controller and a motor.
[0099] In order to enable the printing body 10 to distinguish the state of the blocking member 200 in the paper tray 20, the inventor designed the following solution:
[0100] The printing main body 10 is provided with a position sensor 11 for detecting a position signal. The position sensor 11 is arranged towards the mounting end 21 of the paper cassette 20.
[0101] As shown in Figures 16-22 , reference is made to Figure 15 , Figure 3 and Figure 5 if necessary. The paper cassette 20 further comprises a position detecting member 500, which is located on the side of the mounting shell 100 away from the bearing space 130. The position detecting member 500 extends along the paper movement direction M, and along the paper movement direction M, the position detecting member 500 comprises oppositely arranged abutting end 501 and detecting end 502, the abutting end 501 is used to abut against the blocking member 200, and the detecting end 502 is exposed to the mounting end 21 of the paper cassette 20 and is used to adapt with the position sensor 11. When the blocking member 200 switches between the storage position 201 and the unfolded position 202, the baffle 210 moves by driving the abutting end 501, thereby driving the position detecting member 500 to move and changing the position of the detecting end 502. The position sensor 11 detects the position of the detecting end 502 of the detecting member, which can reflect the state of the blocking member 200, so as to reflect the size of the paper carried in the bearing space 130.
[0102] In the embodiment, the position detecting member 500 comprises a transmission part 510 and a detecting part 520, the transmission part 510 is located in the accommodation space 410 surrounded by the bottom shell 400 and the mounting shell 100, and extends along the paper movement direction M. The detecting part 520 is fixed to the end of the transmission part 510 away from the blocking member 200, and extends out of the accommodation space 410, which extends upward along the thickness direction H and is located at the mounting end 21. Therefore, the detecting part 520 serves as the detecting end 502 of the position detecting member 500. The end of the transmission part 510 away from the detecting part 520 serves as the abutting end 501.
[0103] It should be noted that the above-mentioned "the position detecting member 500 extends along the paper movement direction M" should be understood as that the position detecting member 500 has a component in the paper movement direction M, so that one end thereof can abut against the blocking member 200, and the other end thereof can extend out of the accommodation space 410 and be exposed to the mounting end 21 to be detected by the position sensor 11.
[0104] As shown in Figures 16-22 , reference is made to Figure 15 , Figure 3 and Figure 5The position detection member 500 rotates relative to the mounting shell 100 in a plane parallel to the paper movement direction M. In the present embodiment, the transmission portion 510 rotates relative to the mounting shell 100 in a plane parallel to the paper movement direction M. The position detection member 500 further includes a middle portion 503 between the abutting end 501 and the detection end 502, and the middle portion 503 is located on the transmission portion 510. The rotation axis of the position detection member 500 is located at the middle portion 503. Through the above arrangement, the position detection member 500 can change its posture, especially the posture of the detection end 502, under the driving of the blocking member 200.
[0105] Specifically, the limiting plate 220 of the blocking member 200 moves away from the bearing space 130 of the mounting shell 100 and abuts against the abutting end 501 of the position detection member 500, and is used to apply a force to the abutting end 501.
[0106] When the blocking member 200 moves between the storage position 201 and the unfolded position 202, the position of the limiting plate 220 in the orthogonal projection of the paper movement direction M changes, and the position of the abutting end 501 of the position detection member 500 changes. When the position of the rotation axis of the position detection member 500 does not change, the position of the other end of the transmission portion 510 away from the abutting end 501 changes in the opposite direction, thereby changing the position of the detection portion 520 (if necessary, combined with Figures 7-14 as shown).
[0107] In the above operation, the position of the detection end 502 can be changed by changing the position of the blocking member 200, and the operation is convenient and realized by mechanical transmission, and the stability is high.
[0108] Combined with Figures 16-22 as shown, the abutting end 501 includes a first abutting unit 511 and a second abutting unit 512, the first abutting unit 511 is farther away from the mounting end 21 than the second abutting unit 512, and along the width direction X, the first abutting unit 511 is farther away from the center of the blocking member 200 than the second abutting unit 512.
[0109] Combined with Figure 16 and Figure 17 as shown, when the blocking member 200 is located at the storage position 201, the limiting plate 220 of the blocking member 200 abuts against the first abutting unit 511.
[0110] Combined with Figures 16-22 as shown, when the blocking member 200 is switched from the storage position 201 to the unfolded position 202, the position of the limiting plate 220 of the blocking member 200 in the width direction X changes, and the limiting plate 220 drives the abutting end 501 of the position detection member 500 to move away from the center of the blocking member 200.
[0111] CombinedFigure 18 and Figure 22 As shown, when the blocking member 200 is in the unfolded position 202, the limiting plate 220 abuts against the second abutting unit 512.
[0112] With the above settings, the position of the blocking member 200 against the abutment end 501 of the position detection member 500 can be changed, thereby changing the position of the detection end 502.
[0113] It should be noted that the width direction X is perpendicular to the paper movement direction M and the thickness direction H.
[0114] Furthermore, Figure 16 and Figure 18 As shown, the cardboard box 20 also includes an elastic member 600. One end of the elastic member 600 is fixed to the mounting shell 100 or the bottom shell 400, and the other end is movably abutted against the position detection member 500 and is used to apply pressure to the position detection member 500 so that the abutting end 501 of the position detection member 500 applies a force to the limiting plate 220 of the blocking member 200 in the direction of the center of the blocking member 200.
[0115] In the above configuration, the blocking member 200 is always subjected to a pushing force, thereby increasing the friction between the edge contact surfaces of the blocking member 200 and the limiting hole 150, and thus allowing the blocking member 200 to be stably positioned in the unfolded position 202 or the retracted position 201. This configuration ensures that the blocking member 200 remains relatively stable in either the unfolded or retracted position 201. During normal operation of the printer 1, unnecessary changes in the position of the blocking member 200 can be effectively reduced or avoided, thereby ensuring the normal operation of the paper.
[0116] Furthermore, such as Figure 6 As shown, the limiting plate 220 includes a first plate 221, a second plate 222, and a third plate 223 connected together, and the planes in which any two of the three are located are perpendicular. The first plate 221 is connected to the baffle 210, and the planes in which the two are located are perpendicular.
[0117] Combination Figure 6 , Figures 16-22 As shown, when the limiting plate 220 is in the unfolded position 202, the plane where the first plate 221 is located is parallel to the paper movement direction M, and the plane where the second plate 222 is located is parallel to the width direction X; and the second abutting unit 512 abuts against the third plate 223.
[0118] When the limiting plate 220 is in the storage position 201, the plane where the first plate 221 is located is parallel to the width direction X, and the plane where the second plate 222 is located is parallel to the paper movement direction M; and the first abutting unit 511 abuts against the smooth connection between the third plate 223 and the first plate 221.
[0119] Through the above setting, the position of the abutting end 501 of the position detection piece 500 can be changed by the simple structure of the limiting plate 220. Meanwhile, the contact area of the limiting plate 220 and the abutting end 501 can be increased by the third plate body 223, so as to ensure the stability of the position switching.
[0120] As described above, and in combination with Figures 1-23 As shown, the position sensor 11 on the printing body 10 is arranged towards the detection end 502, and is used to detect the position of the detection end 502 to determine the position of the blocking piece 200.
[0121] On this basis, the printing body 10 further comprises a controller (not shown), and the controller is electrically connected with the position sensor 11. When the blocking piece 200 is located in the storage position 201, the detection end 502 of the position detection piece 500 is located in the first detection position 504. When the blocking piece 200 is located in the unfolded position 202, the detection end 502 of the position detection piece 500 is located in the second detection position 505.
[0122] When the position sensor 11 detects the detection end 502 and the detection end 502 is located in the first detection position 504, a first position signal is sent. The controller determines that the printer 1 is in the first printing state according to the first position signal. At this time, the blocking piece 200 is located in the storage position 201, in other words, it can be determined according to this that the paper of the first size can be printed at this time.
[0123] When the position sensor 11 detects the detection end 502 and the detection end 502 is located in the second detection position 505, a second position signal is sent, and the controller determines that the printer 1 is in the second printing state according to the second position signal. At this time, the blocking piece 200 is located in the unfolded position 202, in other words, it can be determined according to this that the paper of the second size can be printed at this time.
[0124] When the position sensor 11 cannot detect the detection end 502, a third position signal is sent, and the controller determines that the printer 1 is in an idle state according to the third position signal. At this time, the printing body 10 and the paper box 20 are separated.
[0125] In the above setting, the position of the detection end 502 of the position detection piece 500 is detected by the position sensor 11, and the state of the blocking piece 200 in the paper box 20 is determined according to the detected position information. The operation is convenient.
[0126] In actual use, the user issues a printing instruction to the printer 1. If the printing state corresponding to the printing instruction does not match the printing state detected by the controller, the controller issues a warning instruction.
[0127] For example, when the user issues a print instruction for printing by using the first size paper, the controller issues a warning instruction when the second position signal is received, i.e. the controller determines that the printer 1 is in the second printing state, or when the third position signal is received. The warning instruction includes, but is not limited to, controlling the indicator light to emit light, controlling the speaker to emit sound, controlling the device connected to the printer 1 to issue a warning, etc. When the user issues a print instruction for printing by using the second size paper, the controller issues the above-mentioned warning instruction when the first position signal is received, i.e. the controller determines that the printer 1 is in the first printing state, or when the third position signal is received.
[0128] Through the above arrangement, the problem that the actual content to be printed and the actual printable capability of the printer 1 do not match can be avoided. In other words, it is ensured that the content to be printed by the user can be matched by using the paper corresponding to the size.
[0129] The preferred embodiments of the present application have been described above with the aid of drawings, and are not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall fall within the scope of the present application.
