  Hereinafter, an embodiment in which a casing for an electric device according to the present invention is embodied in a casing of a portable printer device 100 will be described in detail with reference to the drawings.

(First embodiment)
First, a schematic structure of the portable printer device 100 according to the first embodiment will be described in detail with reference to the drawings. As shown in FIG. 1, the portable printer device 100 has a printer housing 1. The printer housing 1 has a rectangular shape of about “A6 size” or “A7 size” in plan view, and has a substantially rectangular parallelepiped shape with a thickness of about 2 cm. The printer housing 1 includes a main body case 10, a fixed cover body 20, an upper lid 30, and a lower lid 40. The printer housing 1 accommodates an electrical device or the like such as a printing mechanism unit 50 described later.

  The main body case 10 is formed in a substantially box shape and constitutes a main part of the printer housing 1. On the upper surface of the main body case 10, the fixed cover body 20 is disposed on one end side in the long side direction of the main body case 10. Below the fixed cover body 20, a printing mechanism unit 50 described later is disposed.

  The upper surface of the printer housing 1 is composed of a fixed cover body 20 and an upper lid 30. The upper lid 30 is disposed so as to cover the upper portion of the paper storage unit 25 adjacent to the printing mechanism unit 50, and is pivotally supported by the upper lid support mechanism unit 31 at the end facing the fixed cover body 20. (See FIG. 2 (b)). The upper lid support mechanism 31 is arranged so that the rotational axis of the upper lid 30 can slide along the long side direction of the printer housing 1. As a result, the upper lid 30 is in a state of approaching the fixed cover body 20 (hereinafter referred to as the upper lid lock direction C) and the fixed cover body 20 in a state in which the upper portion of the paper storage unit 25 is covered (that is, the upper lid 30 is closed). Can be slid in a direction away from (hereinafter referred to as an upper lid releasing direction O).

  The upper lid 30 has a leaf spring 32 and a lock piece 33. The leaf spring 32 is disposed on the paper storage unit 25 side of the upper lid 30. As shown in FIG. 2A, when the upper lid 30 is closed, the paper 5 in the paper storage unit 25 is pressed downward and pressed against the upper surface of the pickup roller 54. The lock pieces 33 are disposed in the vicinity of both end portions of the side of the upper cover 30 on the fixed cover body 20 side. When the upper lid 30 is closed and slid to the upper lid lock position, the lock piece 33 cooperates with the later-described upper lid lock mechanism 60 to open the upper lid 30 (that is, rotate upward). Restrict.

  When the upper lid 30 is slid in the upper lid releasing direction O from the upper lid locking position to the predetermined upper lid releasing position (see FIG. 2B), the upper lid 30 is released from the restriction by the upper lid locking mechanism 60, The opening operation of the upper lid 30 and the closing operation of the upper lid 30 (that is, the downward rotation operation) can be freely performed. The upper lid locking mechanism 60 will be described in detail later.

  The paper storage unit 25 is formed in a box shape with the top opened, and a partition plate 25 </ b> A disposed inside the main body case 10 constitutes the bottom surface of the paper storage unit 25. When the top cover 30 is opened (see FIG. 2A), the sheet storage unit 25 can store a plurality of sheets 5 as recording media in a stacked state through the opening of the sheet storage unit 25. The sheet 5 is cut sheet-like thermal paper. The thermal paper includes a thermal coloring type and a thermal perforation type.

  The paper discharge port 15 is formed between the upper lid 30 located at the upper lid lock position and the fixed cover body 20. The paper discharge port 15 discharges the paper 5 conveyed from the paper storage unit 25 via the printing mechanism unit 50 to the outside of the printer housing 1. A pair of finger rests 16 are formed on both sides in the width direction of the portable printer device 100 in the vicinity of the end of the upper lid 30 on the paper discharge port 15 side. The finger placement portion 16 is formed by applying a non-slip process to the surface of the upper lid 30. When performing the sliding movement of the upper lid 30 or the like, the user puts his / her finger (for example, thumb) on the finger rest portion 16 and operates the upper lid 30, so that the sliding movement of the upper lid 30 is surely performed with a small force. Etc. can be performed.

  Here, the printing mechanism unit 50 in the portable printer device 100 will be described with reference to the drawings. The printing mechanism unit 50 includes a thermal head 51, a platen roller 52, a paper guide 53, a pickup roller 54, and a separation block 55.

  The thermal head 51 is a line head type thermal head, and has a plurality of heating elements in a direction orthogonal to the conveyance direction of the paper 5. The portable printer device 100 can print characters, images, and the like for each line extending in a direction orthogonal to the conveyance direction of the paper 5. Note that the print width when printing one line is set to be approximately equal to the width of the short print on the paper 5. Further, the thermal head 51 is pivotally supported around a pivoting support part, and can be brought into contact with and separated from the upper peripheral surface of the platen roller 52 by turning around the pivotal support part. It is. A coil spring 58 is engaged with the back surface (upper surface side) of the thermal head 51. The heating element portion of the thermal head 51 is biased toward the platen roller 52 by the coil spring 58 and abuts against the upper surface of the platen roller 52.

  The platen roller 52 is rotatably supported below the heating element portion of the thermal head 51 and is driven to rotate according to the drive of a drive motor (not shown). The platen roller 52 conveys the paper 5 toward the paper discharge port 15 and sandwiches the paper 5 conveyed to the upper peripheral surface of the platen roller 52 together with the heating element portion of the thermal head 51. Thereby, the heat of the heating element portion of the thermal head 51 is reliably transmitted to the paper 5 which is thermal paper. Thereby, the portable printer device 100 can perform desired printing on the paper 5.

  The paper guide 53 guides the paper 5 conveyed from the paper storage unit 25 to the heating element portion of the thermal head 51 and the upper surface of the platen roller 52 along the outer peripheral surface of the platen roller 52. The paper guide 53 has a curved surface on the surface facing the outer peripheral surface of the platen roller 52. The curved surface is formed along the outer peripheral surface of the platen roller 52. The paper guide 53 is urged toward the platen roller 52 by a pressing coil spring 56 disposed on the back side of the paper guide 53.

  The pickup roller 54 and the separation block 55 are disposed in a portion adjacent to the paper storage unit 25 of the printing mechanism unit 50 (see FIG. 2 and the like). The pickup roller 54 is rotationally driven by driving of a drive motor (not shown), and conveys the paper 5 from the paper storage unit 25 toward the printing mechanism unit 50. As described above, the paper 5 is pressed toward the partition plate 25 </ b> A by the leaf spring 32 in the paper storage unit 25. Accordingly, among the sheets 5 stored in the sheet storage unit 25, the lowermost sheet 5 contacts the upper surface of the pickup roller 54. Accordingly, the pickup roller 54 can convey the paper 5 by rotating as the drive motor is driven.

  The separation block 55 is disposed in the vicinity of the platen roller 52 and the pickup roller 54 on the downstream side in the conveyance direction of the paper 5. The separation block 55 cooperates with the rotational drive of the pickup roller 54 to separate the sheets 5 conveyed from the sheet storage unit 25 one by one. As a result, only the lowermost sheet 5 in the sheet storage unit 25 passes between the separation block 55 and the guide plate 57 disposed below the printing mechanism unit 50.

  An operation during printing by the printing mechanism unit 50 will be described. When printing on the paper 5 is started, first, the pickup roller 54 is rotationally driven in accordance with the drive of the drive motor, and the paper 5 in the paper storage unit 25 is conveyed toward the separation block 55. By the cooperation of the pickup roller 54 and the separation block 55, the paper 5 is separated and conveyed. The separated sheet 5 reaches the lower portion of the curved surface of the paper guide 53 along the upper surface of the guide plate 57. The sheet 5 is conveyed between the outer peripheral surface of the platen roller 52 and the curved surface of the paper guide 53 according to the rotational drive of the platen roller 52, and is guided below the heating element portion of the thermal head 51. When the sheet reaches below the heating element portion of the thermal head 51, the sheet 5 is pressed toward the platen roller 52 by the thermal head 51. At this time, desired printing is performed on the surface of the paper 5 by the heating element of the thermal head 51. The printed paper 5 is discharged to the outside of the printer housing 1 through the paper discharge port 15 in accordance with the rotational drive of the platen roller 52.

  Next, the upper lid lock mechanism 60 that locks the upper lid 30 in the closed state will be described in detail with reference to the drawings. The upper lid locking mechanism 60 cooperates with the lock piece 33 formed on the upper lid 30 and holds the upper lid 30 in a closed state.

  The upper lid lock mechanism 60 is disposed in the vicinity of the fixed cover body 20 along both long sides of the main body case 10. That is, in the portable printer device 100, the two upper lid lock mechanisms 60 are provided, but the configuration is symmetrical. Therefore, the configuration of one upper lid locking mechanism 60 will be described, and the description of the other upper lid locking mechanism 60 will be omitted.

  As shown in FIG. 3, the upper lid lock mechanism 60 includes a guide support block 61, an operation member 62, a resin spring body 63, and an interlocking link body 65. The guide support block 61 is fixed inside the main body case 10 along a pair of long sides of the main body case 10 at a position corresponding to the lock piece 33 of the upper lid 30. The guide support block 61 is formed in a substantially rectangular parallelepiped shape having long sides in the conveyance direction of the paper 5.

  The guide support block 61 includes a vertical guide groove 61A, a horizontal guide groove 61B, and a window portion 61C. The longitudinal guide groove 61A is formed in a concave shape having an open surface on the inner side surface of the guide support block 61 (the surface on the side of the central axis in the longitudinal direction of the main body case 10). The vertical guide groove 61A extends in the vertical direction, and is formed so that the lock piece 33 can be moved up and down.

  The lateral guide groove 61 </ b> B is formed in a concave shape along the longitudinal direction of the guide support block 61 on the outer side surface of the guide support block 61 (surface facing the long side surface of the main body case 10). The lateral guide groove 61B holds the operating member 62 so as to be slidable.

  The window portion 61 </ b> C is formed in the inner surface of the guide support block 61. The first restriction block 62A and the second restriction block 62B are inserted through the window portion 61C. Further, the window portion 61C regulates the slide movement distance of the operating member 62 within a certain range.

  The actuating member 62 is fitted in the lateral guide groove 61B, and is attached so as to be slidable in the front-rear direction (longitudinal direction of the guide support block 61). The operation member 62 includes a first restriction block 62A, a second restriction block 62B, and a groove 62C.

  The first restricting block 62A protrudes laterally at a position spaced apart from the second restricting block 62B by the same distance as the width dimension of the longitudinal guide groove 61A. The second restriction block 62 </ b> B protrudes laterally at one end of the actuating member 62 (end on the side of the paper storage unit 25). The second restriction block 62B has an inclined surface on the lower surface side. The inclined surface is inclined so as to be in a lower position toward the first restriction block 62A.

  The groove 62C is configured by an interval formed between the first restriction block 62A and the second restriction block 62B. The groove part 62C has the same width as the vertical guide groove 61A and extends in the vertical direction.

  The actuating member 62 is connected to the interlocking link body 65 via a pin and a vertically long hole at the end opposite to the end where the second restricting block 62B and the like are formed.

  The resin spring body 63 is attached to the guide support block 61 by engaging one end thereof with an engagement portion formed on the outer surface of the guide support block 61. A free end side portion (hereinafter referred to as a tip portion) of the resin spring body 63 is fitted in the vertical guide groove 61 </ b> A and is urged upward by the elastic force of the resin spring body 63.

  The interlocking link body 65 is connected to the end portion of the operating member 62 and is rotatably fitted to the rotation shaft of the platen roller 52. Accordingly, the interlocking link body 65 rotates about the rotation axis of the platen roller 52 in accordance with the sliding movement of the operation member 62.

  The interlocking link body 65 includes a first cam body 65A and a second cam body 65B. The first cam body 65 </ b> A contacts or separates from the front surface of the paper guide 53 according to the rotation of the interlocking link body 65. The second cam body 65B is formed integrally with the first cam body 65A. Accordingly, the second cam body 65B contacts or separates from the lower surface of the thermal head 51 in conjunction with the contact or separation of the first cam body 65A (that is, the rotation of the interlocking link body 65).

  Next, the operation of the upper lid lock mechanism 60 when moving the upper lid 30 to the upper lid lock position will be described with reference to the drawings. When moving the upper lid 30 to the upper lid lock position, the user rotates the upper lid 30 downward so as to cover the paper storage unit 25 and then slides the upper lid 30 in the upper lid locking direction C.

  When the upper lid 30 is opened, the groove 62C of the operating member 62 is aligned with the vertical guide groove 61A and communicates in the vertical direction (see FIG. 3C). As a result, the distal end portion of the resin spring body 63 enters upward into the groove 62 </ b> C by the elastic force of the resin spring body 63. The sliding movement of the operating member 62 is restricted by the tip of the resin spring body 63 located in the groove 62C.

  When the user rotates the upper lid 30 downward and reaches a position where the upper lid 30 covers the upper side of the paper storage unit 25, the lock piece 33 of the upper lid 30 enters the vertical guide groove 61A from above, and the operating member 62 Is located inside the groove 62C (see FIG. 3B). At this time, the lock piece 33 abuts on the tip of the resin spring body 63 located in the groove 62C, and the tip of the resin spring body 63 is below the groove 62C (that is, below the vertical guide groove 61A). Extrude. Here, the upper lid 30 and the operating member 62 are arranged so as to be slidable in the upper lid locking direction C. Therefore, the operating member 62 can be slid in the upper lid locking direction C by pushing the tip of the resin spring body 63 out of the groove 62C.

  Thereafter, when the user slides and moves the upper lid 30 covering the upper portion of the paper storage unit 25 in the upper lid locking direction C, the lock piece 33 slides in the upper lid locking direction C while being in contact with the first restriction block 62A. To do. That is, the operating member 62 slides in the upper lid locking direction C along the lateral guide groove 61B in conjunction with the sliding movement in the upper lid locking direction C of the upper lid 30.

  At this time, in conjunction with the sliding movement in the upper lid locking direction C of the operating member 62, the interlocking link body 65 rotates clockwise. That is, the first cam body 65 </ b> A rotates in a direction away from the front surface of the paper guide 53. Accordingly, the paper guide 53 is urged toward the outer peripheral surface of the platen roller 52 by the urging force of the pressing coil spring 56. Further, the second cam body 65 </ b> B rotates in a direction away from the lower surface of the thermal head 51 by the rotation of the interlocking link body 65. Accordingly, the heating element portion of the thermal head 51 is pressed against the upper surface of the platen roller 52 by the urging force of the coil spring 58. Therefore, the portable printer device 100 can be reliably printed by locking the upper lid 30.

  When the upper lid 30 is located at the upper lid lock position, the lock piece 33 is located on the fixed cover body 20 side of the window portion 61C (see FIG. 3A). At this time, the upper surface of the window portion 61 </ b> C is positioned above the lock piece 33. Therefore, the upper lid 30 is in a state where the upward rotation is restricted, and the opening of the upper lid 30 is locked.

  Next, the operation of the upper lid lock mechanism 60 when the upper lid 30 is unlocked will be described. In this case, the user slides the upper lid 30 positioned at the upper lid lock position in the upper lid release direction O to the upper lid release position (see FIG. 3B).

  When the upper lid 30 is slid in the upper lid release direction O from the upper lid lock position, the lock piece 33 slides in the upper lid release direction O while being in contact with the second restriction block 62B. That is, the operating member 62 slides in the upper lid releasing direction O along the lateral guide groove 61B in conjunction with the sliding movement in the upper lid releasing direction O of the upper lid 30.

  Here, the interlocking link body 65 rotates counterclockwise in conjunction with the sliding movement in the upper lid releasing direction O of the operating member 62. That is, the first cam body 65 </ b> A rotates in a direction in contact with the front surface of the paper guide 53. Accordingly, the paper guide 53 is separated from the outer peripheral surface of the platen roller 52 against the urging force of the pressing coil spring 56. Further, the second cam body 65 </ b> B rotates in a direction in contact with the lower surface of the thermal head 51 by the rotation of the interlocking link body 65. Accordingly, the heating element portion of the thermal head 51 is separated from the upper surface of the platen roller 52 against the urging force of the coil spring 58. Therefore, the portable printer device 100 is in a state in which the paper 5 or the like that has caused the conveyance failure can be easily removed by releasing the lock of the upper lid 30.

  When the upper lid 30 is positioned at the upper lid release position, the groove 62C of the operating member 62 communicates with the vertical guide groove 61A of the guide support block 61 in the vertical direction. Thereby, the front-end | tip part of the resin spring body 63 approachs into the groove part 62C from the lower part of 61 A of vertical guide grooves, and contact | abuts from the downward direction to the lock piece 33 located in the groove part 62C (refer FIG.3 (b) (c)). . Since the upper part of the vertical guide groove 61A and the groove part 62C communicate with each other in the vertical direction, the lock piece 33 can be moved upward without any restriction. That is, as a result, the upper lid 30 can be turned upward, and the lock by the upper lid lock mechanism 60 is released.

  Next, the configuration of the lower surface side (the surface facing the fixed cover body 20 and the upper lid 30) of the printer housing 1 will be described in detail with reference to the drawings. As shown in FIG. 4, the printer housing 1 has a battery housing portion 45 on the lower surface side of the main body case 10. The battery storage unit 45 according to the first embodiment is formed at the end on the same side as the paper storage unit 25 (that is, the end opposite to the fixed cover body 20) on the lower surface side of the main body case 10. The battery storage unit 45 is formed in a box shape in which the lower surface side of the fixed cover body 20 is opened, and stores a battery 70 that functions as a power source for the portable printer device 100 therein. Further, as shown in FIG. 6, the bottom surface of the battery storage unit 45 is configured by a partition plate 25 </ b> A, like the paper storage unit 25.

  A lower lid 40 is attached to the opening of the battery housing 45 so as to be slidable along the opening edge of the battery housing 45. Accordingly, the lower surface of the printer housing 1 is constituted by the lower surface of the main body case 10 and the lower lid 40. When slid in the lower lid locking direction L and positioned at the lower lid locking position (see FIG. 6A), the lower lid 40 is moved to the battery storage portion 45 by the lower lid locking piece 41 and the engaging portion 46, which will be described later. Is locked in a closed state. In addition, when the slider slides in the lower lid release direction U from the lower lid lock position (see FIG. 6A) and is located at the lower lid release position (see FIG. 6B), the lower lid 40 is moved to the battery housing portion 45. Can be detached from the battery storage unit 45. The configuration of the lower lid 40 will be described in detail later.

  The battery storage unit 45 includes an engagement unit 46 and a guide wall 47. Two engaging portions 46 are formed in the vicinity of two end edges orthogonal to the sliding movement direction of the lower lid 40 (lower lid locking direction L and lower lid releasing direction U) among the opening edges of the battery storage portion 45. It is installed. When the lower lid 40 is slid in the lower lid locking direction L, each engaging portion 46 is inserted by a lower lid locking piece 41 formed on the lower lid 40. That is, when the lower lid 40 is located at the lower lid lock position, the engaging portion 46 cooperates with the lower lid lock piece 41 of the lower lid 40 to lock the lower lid 40 at the lower lid lock position.

  The guide wall 47 is erected from the bottom surface of the battery storage unit 45 at two locations along the long side of the printer housing 1. That is, each guide wall 47 is formed in a wall shape extending along the sliding direction of the lower lid 40 (that is, the lower lid locking direction L and the lower lid releasing direction U). When the lower lid 40 slides, the guide wall 47 abuts on the lower lid 40 (for example, the guide piece 43) to guide the sliding movement direction of the lower lid 40 in a predetermined direction. The guide wall 47 is positioned along the side surface of the battery 70 when the battery 70 is stored in the battery storage unit 45. Accordingly, the guide wall 47 serves to guide the battery 70 stored in the battery storage unit 45 to a predetermined mounting position.

  The guide wall 47 on the center side in the width direction of the printer housing 1 is formed at a position spaced apart from a side surface of the battery storage unit 45 by a predetermined dimension. A space between the guide wall 47 and one side surface of the battery housing 45 functions as a guide groove 47A. When sliding the lower lid 40, one side surface of the lower lid 40 moves in the guide groove 47A. Therefore, the guide groove 47A guides the sliding movement direction of the lower lid 40 in a predetermined direction.

  The guide wall 47 has a vertical movement restricting piece 49 at a predetermined position on the outer side surface of the battery housing part 45. The vertical movement restricting piece 49 protrudes by a predetermined dimension in the outer direction of the battery housing part 45. When the lower lid 40 is positioned at the lower lid lock position, the vertical movement restricting piece 49 abuts on the lower surface of the guide piece 43 formed on the lower lid 40 on the upper surface of the vertical movement restricting piece 49. That is, the lower lid 40 is restricted from moving in the vertical direction by the guide piece 43 of the lower lid 40 and the vertical movement restriction piece 49 of the guide wall 47.

  The guide wall 47 has a convex portion 48 having a substantially triangular shape in side view on the lower surface of the guide wall 47. The convex part 48 regulates the sliding movement of the lower lid 40 in an auxiliary manner by cooperating with a slide regulating piece 42 of the lower lid 40 described later. This will be described in detail later with reference to the drawings.

  As shown in FIGS. 4 and 5, the lower lid 40 includes a lower lid locking piece 41 protruding in the lower lid locking direction L, a slide regulating piece 42 having a substantially triangular shape in side view, and a guide piece 43. Have. Four lower lid lock pieces 41 are formed at positions corresponding to the engaging portions 46 in the battery housing portion 45. The lower lid lock piece 41 has an engaging claw (not shown) at the distal end portion of the lower lid lock piece 41. When the lower lid 40 is located at the lower lid lock position (see FIG. 6A), the engagement claw of the lower lid lock piece 41 is engaged with the opening edge of the engagement portion 46 of the battery storage portion 45. That is, when the lower lid 40 is positioned at the lower lid lock position, the lower lid lock piece 41 cooperates with the engaging portion 46 to slide the lower lid 40 (that is, to open the lower lid 40). Lock it.

  One slide regulating piece 42 is formed on each of the inner surfaces of the lower lid 40 (surfaces on the battery storage unit 45 side) at predetermined positions facing the lower surfaces of the two guide walls 47. The slide regulating piece 42 protrudes from the inner surface of the lower lid 40 toward the lower surface of the guide wall 47 by a predetermined dimension. When the lower lid 40 is slid, the slide restricting piece 42 comes into contact with a convex portion 48 that is formed to protrude from the lower surface of the guide wall 47 to supplementarily restrict the sliding movement of the lower lid 40.

  Two guide pieces 43 are formed on each side of the lower lid 40 along the slide movement direction so as to be separated from each other. The guide piece 43 is formed so as to protrude inward of the battery housing part 45, and comes into contact with a guide wall 47 erected on the battery housing part 45 when the lower lid 40 is slid. That is, the guide piece 43 cooperates with the guide wall 47 to guide the sliding movement direction of the lower lid 40 in the lower lid locking direction L or the lower lid releasing direction U. When the lower lid 40 is positioned at the lower lid lock position, the lower surface of each guide piece 43 comes into contact with the upper surface of the vertical movement restricting piece 49 described above. That is, the lower lid 40 is restricted from moving in the vertical direction by the guide piece 43 of the lower lid 40 and the vertical movement restriction piece 49 of the guide wall 47.

  A finger rest 44 is formed on the surface of the lower lid 40 in the form of a band over the width direction of the lower lid 40. The finger placement portion 44 is formed slightly downstream of the lower lid release direction U on the surface of the lower lid 40.

  Each slide regulating piece 42 is sandwiched between two guide pieces 43 formed on each side along the slide movement direction of the lower lid 40 and is formed at a position spaced apart from each guide piece 43 by a predetermined dimension. . Further, the slide regulating piece 42 is provided at a position different from the finger placement portion 44 of the lower lid 40. Therefore, when the lower lid 40 is opened and closed using the finger placement portion 44, the vicinity of the slide restricting piece 42 of the lower lid 40 can be sufficiently bent according to the convex portion 48 of the guide wall 47. As a result, the lower lid 40 can easily open and close the lower lid 40 sufficiently.

  Next, in the printer casing 1 according to the first embodiment, the operation of the lower lid 40 when the upper lid 30 is locked will be described in detail with reference to FIG. FIG. 6 is a cross-sectional view of the printer housing 1 shown in FIG. 4 as viewed in the direction of arrow C. For convenience, the printer housing 1 is rotated 180 degrees so that the upper lid 30 is up and the lower lid 40 is down.

  As described above, when the lower lid 40 is located at the lower lid lock position, the lower lid 40 is locked at the lower lid lock position by the cooperation of the lower lid lock piece 41 and the engaging portion 46. At this time, as shown in FIG. 6A, the slide restricting piece 42 of the lower lid 40 is located at a position upstream of the convex portion 48 formed on the lower surface of the guide wall 47 in the lower lid releasing direction U. 48 is adjacent.

  Here, the upper lid 30 is slid in the upper lid locking direction C toward the upper lid locking position. FIG. 6A shows a state in which the upper lid 30 is in the upper lid lock position, unlike the description here. In this case, the user slides the upper lid 30 in the upper lid locking direction C while pressing the upper lid 30 toward the lower surface of the printer housing 1. At this time, in order to fix the printer casing 1 in a predetermined position, the user applies a force pressing from the lower lid 40 to the upper surface of the printer casing 1 opposite to the force pressing from the upper lid 30 to the lower surface of the printer casing 1. Let

  As an example of such a state, for example, there is a state where the user holds the two long sides of the printer housing 1 with his / her hands. In this case, the thumb of the user's hand applies a force toward the lower surface of the printer housing 1 (downward force in FIG. 6) to the upper lid 30, and the other four fingers in the user's hand are the lower lid 40. In contrast, a force toward the upper surface of the printer housing 1 (upward force in FIG. 6) is applied. That is, by applying a force in this way, the frictional force between the finger and the printer housing 1 is increased, and the position of the printer housing 1 is fixed in the hand. In this case, the user's thumb applies a force in the upper lid locking direction C to the upper lid 30. Accordingly, the finger does not slide on the surface of the upper lid 30, and the upper lid 30 slides in the upper lid locking direction C with respect to the main body case 10 that is fixed.

  Here, when a force that slides the upper lid 30 in the upper lid locking direction C is applied to the upper lid 30, if the lower lid 40 is pressed toward the upper surface side of the printer housing 1, the lower lid 40. A reaction force of a force that slides the upper lid 30 in the upper lid locking direction C acts. That is, a force that slides the lower lid 40 in the lower lid releasing direction U (that is, the direction opposite to the upper lid locking direction C) acts on the lower lid 40.

  When the lower lid 40 tries to slide in the lower lid release direction U due to the reaction force, the slide regulating piece 42 formed on the lower lid 40 is a convex portion located on the downstream side of the lower lid release direction U. 48 abuts. That is, when the upper lid 30 is slid in the upper lid locking direction C, the lower lid 40 restricts the sliding movement from the lower lid locking position to the lower lid releasing direction U by the contact of the slide regulating piece 42 and the convex portion 48. Is done.

  Also in this state, a force toward the lower surface of the printer housing 1 acts on the upper lid 30, and a force toward the upper surface of the printer housing 1 acts on the lower lid 40. That is, when the lower lid 40 slides in the lower lid release direction U, the slide restricting piece 42 moves downward toward the upper surface of the guide wall 47, thereby causing the convex portion 48 in the protruding direction of the slide restricting piece 42. The overlapping part becomes larger. That is, the slide restricting piece 42 comes into contact (interference) more strongly with the convex portion 48. As a result, when the upper lid 30 is slid and moved in the upper lid locking direction C, the printer housing 1 moves the lower lid 40 from the lower lid locking position to the lower lid releasing direction U by the slide regulating piece 42 and the convexity. The contact of the portion 48 can surely regulate.

  When the lower lid 40 is slid in the lower lid locking direction L and moved to the lower lid locking position, the slide restricting piece 42 moves in the lower lid locking direction L while being in contact with the lower surface of the guide wall 47. At this time, the slide regulating piece 42 comes into contact with the convex portion 48 from the upstream side in the lower lid locking direction L (see FIG. 6B). The inclined surfaces of the slide restricting piece 42 and the convex portion 48 facing each other are in sliding contact with each other, so that the slide restricting piece 42 gets over the convex portion 48 in the lower lid locking direction L. In order for the slide restricting piece 42 to get over the convex portion 48 in the lower lid locking direction L, the lower lid 40 needs to be locally bent and moved to the lower surface side of the printer housing 1. Thereafter, the lower lid 40 moves to the lower lid lock position and is locked by the cooperation of the lower lid lock piece 41 and the engaging portion 46 (see FIG. 6A).

  As described above, the printer housing 1 according to the first embodiment includes the upper lid 30 that is slidably attached to the upper surface of the opposite end portion of the fixed cover body 20, and the lower surface of the same end portion as the upper lid 30. And a lower lid 40 slidably attached. The upper lid 30 is locked by sliding to the upper lid locking position according to the upper lid locking direction C, and is unlocked by sliding to the upper lid releasing position according to the upper lid releasing direction O. The lower lid 40 is locked by sliding to the lower lid locking position according to the lower lid locking direction L (that is, the same direction as the upper lid locking direction C), and the lower lid 40 is locked in the lower lid releasing direction U (that is, the upper lid releasing direction O). The lock is released by sliding from the lower lid lock position according to the same direction). This embodiment is particularly effective when the user tries to open and close the upper lid 30 without using the finger placement unit 16 and holding the finger between the upper lid 30 and the lower lid 40.

  In the printer housing 1, when the upper lid 30 or the lower lid 40 is slid (locked or unlocked), the printer housing 1 is fixed by the force from the upper surface to the lower surface and the force from the lower surface to the upper surface. Therefore, it is necessary to slide the upper lid 30 or the lower lid 40. Here, when the upper lid 30 is slid to the upper lid locking position according to the upper lid locking direction C, if a force is applied to the lower lid 40 from the lower surface to the upper surface, the upper lid 30 is slid in the upper lid locking direction C. The reaction force of the moving force acts as a force for moving the lower lid 40 in the lower lid releasing direction U.

  In the printer housing 1 according to the first embodiment, when the lower lid 40 is about to slide in the lower lid release direction U under this situation, the slide regulating piece 42 and the convex portion 48 of the lower lid 40 are in contact with each other. (See FIG. 6 (a)). Therefore, the printer housing 1 can restrict the sliding movement of the lower lid 40 in the lower lid releasing direction U in this case. Accordingly, the printer housing 1 can prevent the lower lid 40 from being unlocked when the upper lid 30 is locked. Further, since a force from the lower surface to the upper surface acts on the lower lid 40, the overlapping portions of the slide restricting piece 42 and the convex portion 48 become larger in the vertical direction, and contact (interference) more strongly. Accordingly, the printer casing 1 can reliably prevent the unlocking of the lower lid 40 in this case while effectively utilizing the force required to fix the printer casing 1 when the upper lid 30 is locked.

  The lower lid 40 covers the battery storage unit 45 in which the battery 70 is stored. When the upper cover 30 is locked, if the lower cover 40 is unlocked, the battery 70 stored in the battery storage unit 45 may fall out of the battery storage unit 45 regardless of the user's intention. In this regard, the printer housing 1 according to the first embodiment can prevent a situation where the lock of the lower lid 40 is released as the upper lid 30 slides in the upper lid locking direction C. That is, the printer housing 1 can prevent an accident or the like due to the dropping of the battery 70 stored in the battery storage unit 45.

(Second Embodiment)
Next, an embodiment (hereinafter, a second embodiment) different from the first embodiment described above will be described in detail with reference to the drawings. Also in the second embodiment, the case where the present invention is applied to the casing of the portable printer device 100 will be described.

  The printer housing 1 according to the second embodiment has a fixed cover body 20 and an upper lid 30 on the upper surface. About the structure of this fixed cover body 20 and the upper cover 30, it is the same structure as 1st Embodiment. That is, the upper lid 30 is arranged so as to be slidable and rotatable with respect to the main body case 10 by the upper lid support mechanism 31 as in the first embodiment. Similarly to the first embodiment, when the upper lid 30 slides to the upper lid lock position according to the upper lid lock direction C, the upper lid 30 is locked by the upper lid lock mechanism 60 (see FIGS. 2 and 3). The upper lid 30 is configured to be able to open the upper portion of the paper storage unit 25 by sliding in the upper lid releasing direction O from the upper lid lock position. Since these points have already been described in the above-described first embodiment, a detailed description thereof will be omitted.

  In the printer housing 1 according to the second embodiment, the lower lid 40 is attached to the end portion on the fixed cover body 20 side, unlike the first embodiment. Similarly to the first embodiment, the lower lid 40 is attached to the opening edge of the battery storage unit 45 that stores the battery 70. In the second embodiment, only the positions of the lower lid 40 and the battery storage portion 45 with respect to the main body case 10 are different (see FIG. 7). The configuration of the lower lid 40 and the configuration of the battery storage portion 45 are the same as those of the first embodiment. This is the same as the embodiment. Since the configurations of the lower lid 40 and the battery storage unit 45 have already been described in the first embodiment, description thereof will be omitted.

  Also in the printer casing 1 according to the second embodiment, when the upper lid 30 is slid in the upper lid releasing direction O from the upper lid locking position, the user releases the upper lid while pressing the upper lid 30 toward the lower surface of the printer casing 1. Slide in direction O. At this time, in order to fix the printer casing 1 in a predetermined position, the user applies a force pressing from the lower lid 40 to the upper surface of the printer casing 1 opposite to the force pressing from the upper lid 30 to the lower surface of the printer casing 1. Let

  Here, when a force for sliding the upper lid 30 in the upper lid releasing direction O is applied to the upper lid 30, if the lower lid 40 is pressed toward the upper surface side of the printer housing 1, the lower lid 40. In this case, a reaction force of the force that slides the upper lid 30 in the upper lid releasing direction O acts. That is, a force that slides the lower lid 40 in the lower lid release direction U (that is, the direction opposite to the upper lid release direction O in the second embodiment) acts on the lower lid 40.

  Due to the reaction force, even in the printer housing 1 according to the second embodiment, when the lower lid 40 is about to slide in the lower lid release direction U, the slide regulating piece 42 formed on the lower lid 40 is Then, it comes into contact with the convex portion 48 located downstream of the lower lid releasing direction U. That is, in the second embodiment, when the upper lid 30 is slid in the upper lid release direction O, the lower lid 40 is moved from the lower lid lock position to the lower lid release direction by the contact of the slide regulating piece 42 and the convex portion 48. Slide movement to U is restricted.

  Also in this state, a force toward the lower surface of the printer housing 1 acts on the upper lid 30, and a force toward the upper surface of the printer housing 1 acts on the lower lid 40. That is, when the lower lid 40 slides in the lower lid release direction U, the slide restricting piece 42 moves upward toward the lower surface of the guide wall 47, so that the convex portion 48 in the projecting direction of the slide restricting piece 42. The overlapping part becomes larger. That is, the slide restricting piece 42 comes into contact (interference) more strongly with the convex portion 48. As a result, when the upper lid 30 is slid in the upper lid release direction O, the printer housing 1 according to the second embodiment slides the lower lid 40 from the lower lid lock position to the lower lid release direction U. By the contact of the restricting piece 42 and the convex portion 48, it can be reliably restricted. The convex portion 48 is desirably provided at a position facing the finger placement portion 16 in the upper lid 30.

  Also in the second embodiment, when the lower lid 40 is slid in the lower lid locking direction L and moved to the lower lid locking position, the slide regulating piece 42 is in contact with the lower surface of the guide wall 47 and the lower lid lock Move in direction L. At this time, the slide restricting piece 42 comes into contact with the convex portion 48 from the upstream side in the lower lid locking direction L. Then, when the slide regulating piece 42 gets over the convex portion 48 in the lower lid locking direction L, the lower lid 40 moves to the lower lid locking position and is locked by the cooperation of the lower lid locking piece 41 and the engaging portion 46. Is done.

  As described above, the printer housing 1 according to the second embodiment includes the upper lid 30 that is slidably attached to the upper surface of the opposite end portion of the fixed cover body 20, and the lower surface of the upper lid 30 and the opposite end portion. And a lower lid 40 that is slidably attached. The upper lid 30 is locked by sliding to the upper lid locking position according to the upper lid locking direction C, and is unlocked by sliding to the upper lid releasing position according to the upper lid releasing direction O. The lower lid 40 is locked by sliding to the lower lid locking position according to the lower lid locking direction L (that is, the same direction as the upper lid releasing direction O), and the lower lid 40 is locked in the lower lid releasing direction U (that is, the upper lid locking direction C). The lock is released by sliding from the lower lid lock position according to the same direction).

  In the printer housing 1, when the upper lid 30 or the lower lid 40 is slid (locked or unlocked), the printer housing 1 is fixed by the force from the upper surface to the lower surface and the force from the lower surface to the upper surface. Therefore, it is necessary to slide the upper lid 30 or the lower lid 40. Here, when the upper lid 30 is slid from the upper lid locking position according to the upper lid releasing direction O, if a force from the lower surface to the upper surface is applied to the lower lid 40, the upper lid 30 is slid in the upper lid releasing direction O. The reaction force of the moving force acts as a force for moving the lower lid 40 in the lower lid releasing direction U.

  In the printer housing 1 according to the second embodiment, when the lower lid 40 is about to slide in the lower lid release direction U under this situation, the slide regulating piece 42 and the convex portion 48 of the lower lid 40 are in contact with each other. Touch. Therefore, the printer housing 1 can restrict the sliding movement of the lower lid 40 in the lower lid releasing direction U in this case. Accordingly, the printer housing 1 can prevent the lower lid 40 from being unlocked when the upper lid 30 is unlocked. Further, since a force from the lower surface to the upper surface acts on the lower lid 40, the overlapping portions of the slide restricting piece 42 and the convex portion 48 become larger in the vertical direction, and contact (interference) more strongly. Therefore, the printer casing 1 can reliably prevent the unlocking of the lower lid 40 in this case while effectively utilizing the force required to fix the printer casing 1 when the upper lid 30 is unlocked. .

  The lower lid 40 covers the battery storage unit 45 in which the battery 70 is stored. When the upper lid 30 is unlocked, if the lower lid 40 is unlocked, the battery 70 stored in the battery storage section 45 may fall out of the battery storage section 45 regardless of the user's intention. . In this regard, the printer casing 1 according to the second embodiment can prevent the lower lid 40 from being unlocked as the upper lid 30 slides in the upper lid releasing direction O. That is, the printer housing 1 can prevent an accident or the like due to the dropping of the battery 70 stored in the battery storage unit 45.

Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention.
For example, in the above-described embodiment, the slide regulating piece 42 is formed on the lower lid 40, and the convex portion 48 is formed on the lower surface of the guide wall 47 located near the opening edge of the battery housing 45. The invention is not limited to this embodiment. For example, the slide restricting piece 42 may be formed on the lower lid 40, and the recess may be formed near the opening edge of the battery storage unit 45. In this case, when the lower lid 40 is positioned at the lower lid lock position, the slide regulating piece 42 is fitted into the recess. Further, the convex portion 48 may be formed on the opening edge of the battery housing portion 45, and the slide restricting concave portion may be formed on the lower lid. In this case, when the lower lid 40 is positioned at the lower lid lock position, the convex portion 48 is fitted into the slide restricting concave portion. In other words, in the same direction as the force required to fix the printer casing 1, at least one of the lid or the opening edge slidably contacting the lid is provided with a protruding portion, and the other is provided with a receiving portion that interferes with the protruding portion in the sliding movement direction. May be.

  In the above-described embodiment, there are two sets of the slide restricting pieces 42 and the convex portions 48, but the present invention is not limited to this mode. The combination of the slide restricting piece 42 and the convex portion can be appropriately changed according to the configuration of the printer housing 1.

  Furthermore, in the above-described embodiment, the lower lid 40 is locked by the lower lid lock piece 41 and the engaging portion 46 of the battery housing portion 45, the slide regulating piece 42 of the lower lid 40, and the convex portion of the guide wall 47. Although 48 performed the auxiliary | assistant lock function, it is not limited to this aspect. In other words, the lower lid 40 can be configured to be locked by the slide restricting piece 42 and the convex portion 48. In this case, it is desirable to shorten the distance between the slide regulating piece 42 and each guide piece 43. As a result, the amount of bending in the vicinity of the slide restricting piece 42 is reduced, and the slide restricting piece 42 comes into further strong contact with the convex portion 48.
