Can be arranged. When opening the printer cover, the printer cover is slid in the direction along the display panel, and the printer cover is rotated with the platen roller detached from the platen holder. Since the printer cover can be opened and closed without hindrance without having to place the hinge part at a position far away from the initial position of the platen roller in the thickness direction of the case, the thickness of the case can be increased. Can be suppressed.

  Further, according to a second aspect of the present invention, the side edge of the printer cover and the side edge of the opening that contacts the printer cover are formed straight in the sliding direction of the printer cover in a rear view, and are fully closed. A rotation restricting portion for restricting the rotation of the printer cover in a predetermined slide range is provided.

  According to this, since the side edge portion of the printer cover and the side edge portion of the opening are formed straight in the sliding direction in the rear view, and the rotation of the printer cover is restricted within a predetermined sliding range from the fully closed state, Shaking of the printer cover during the sliding operation can be suppressed, and thus the operator can smoothly slide the printer cover.

  According to a third aspect of the present invention, the projecting piece for restricting the rotation of the printer cover in the fully closed state is fitted to the concave portion formed in the housing in the sliding direction of the printer cover. The part is formed.

  According to this, even if the operator erroneously tries to rotate the printer cover in the fully closed state, the rotation of the printer cover is restricted, and therefore, damage to parts due to an erroneous operation can be avoided.

  According to a fourth aspect of the present invention, a gear for transmitting the driving force of the driving motor is provided on the rotation shaft of the platen roller, and the protruding piece is provided so as to cover the gear.

  According to this, the gear is protected by the projecting piece, and it is possible to prevent the gear from being damaged by the operator's finger hitting the gear when the printer cover is opened and closed.

  According to a fifth aspect of the present invention, the hinge portion includes a shaft portion formed in the printer cover and a guide hole formed in the housing, and the slide direction of the printer cover is formed in the guide hole. The shaft portion is configured to be movably movable.

  According to this, the slide operation and the rotation operation of the printer cover can be realized with a simple structure.

  According to a sixth aspect of the present invention, the printer cover protrudes into the guide hole together with the shaft portion and comes into contact with the inner peripheral surface of the guide hole, so that the printer cover is in a predetermined slide range from the fully closed state. It is assumed that a rib for restricting the rotation of the cover is formed.

  According to this, since the rotation of the printer cover is restricted within the predetermined slide range from the fully closed state, it is possible to suppress the rattling of the printer cover during the sliding operation, and thus the operator can slide the printer cover. The operation can be performed smoothly.

  According to a seventh aspect of the present invention, a restriction surface for restricting sliding of the printer cover in a fully opened state is formed on the casing by the ribs coming into contact therewith.

  According to this, even if the operator tries to slide the printer cover accidentally in the fully opened state, the slide of the printer cover is restricted, so that the parts can be prevented from being damaged due to an erroneous operation.

  According to an eighth aspect of the invention, the casing is formed with a rib that protrudes from an inner peripheral surface of the guide hole and holds the shaft portion at a position where the printer cover can be rotated.

  According to this, since the shaft portion of the printer cover is held by the rib, it is possible to suppress the shakiness of the printer cover when the printer cover rotates, and thereby the rotation operation of the printer cover by the operator can be smoothly performed. Can be done. In addition, since the operator can feel a click when the shaft portion of the printer cover rides on the rib, the printer cover can be rotated, that is, the end position in the sliding direction when the printer cover is slid from the fully closed state. The operator can confirm that the printer cover has arrived.

  According to a ninth aspect of the present invention, in the fully closed state of the printer cover, an edge of the printer cover in the vicinity of the hinge portion and an edge of the opening in the housing are connected to the printer cover with respect to the housing. It is set as the structure fitted with the uneven | corrugated cross-sectional shape so that the movement of the thickness direction of this may be controlled.

  According to this, in order to smoothly perform the sliding operation of the printer cover by the operator, even when a relatively large play is given to the hinge portion, the movement of the printer cover with respect to the housing is restricted in the fully closed state. It is possible to suppress rattling of the printer cover in the fully closed state.

It will be a thing.

  FIG. 1 is a perspective view showing a mobile terminal device 1 according to the present embodiment. FIG. 2 is a rear view of the mobile terminal device 1 shown in FIG. FIG. 3 is a cross-sectional view of the mobile terminal device 1 shown in FIG.

  The mobile terminal device 1 is a mobile payment terminal that performs payment using a contact type IC card, a non-contact type IC card, a magnetic card, etc. As shown in FIG. 3 and operation keys 4 are provided.

  The display panel 3 is a so-called touch panel display in which a liquid crystal display and a touch panel are combined. The operation keys 4 are a power key, a settlement key, a function key, a numeric keypad, and the like. A cover 5 is provided on the side surface of the housing 2 to cover the power plug and the memory card slot.

  A recording paper storage unit (recording medium storage unit) 6 that stores therein a roll paper RP in which a recording paper (recording medium) is wound in a roll shape protrudes rearward from the upper portion on the back side of the housing 2. Is formed. The recording paper is so-called thermal paper in which a thermal coloring layer is formed on the printing surface.

  As shown in FIG. 2, a printer cover 7, a camera 8, a speaker 9, a battery cover 10, and a connection terminal 11 are provided on the back side of the housing 2.

  The printer cover 7 closes the opening 12 provided in the recording paper storage unit 6 in order to store the roll paper RP in the recording paper storage unit 6. The camera 8 captures a barcode or the like. The speaker 9 outputs sound such as an alarm sound. The connection terminal 11 is connected to a connection terminal of a cradle (not shown) and supplies power for charging.

  As shown in FIG. 3, the housing 2 includes a printer 15, an IC card reader 16, a magnetic card reader 17, an NFC antenna 18, a communication module 19, control boards 20, 21 and 22, A battery 23 is provided.

  The printer 15 is a so-called thermal printer that prints on recording paper by a thermal method. The mobile terminal device 1 prints a slip after payment is made using a contact IC card, a non-contact IC card, a magnetic card, or the like. When performing the printing, the mobile terminal device 1 uses the printer 15 to print and discharge a slip on the recording paper drawn from the roll paper RP. The IC card reader 16 reads an IC card inserted into an IC card slot 26 provided on the lower surface side of the housing 2. The magnetic card reader 17 reads a magnetic card inserted into a magnetic card slot 27 provided on the lower surface side of the housing 2. The NFC antenna 18 communicates with a non-contact IC card or the like having an electronic money function by NFC (Near Field Communication). That is, the portable terminal device 1 is portable, but has a settlement function and a slip printing function. In addition, an electronic money settlement function, an ID card authentication function, and the like may be provided. The ID card authentication function may be used when, for example, a user of the mobile terminal device 1 is authenticated. The communication module 19 performs wireless communication with a settlement processing system server or the like. The control boards 20, 21, and 22 are mounted with various electronic components for controlling each part of the mobile terminal device 1. The battery 23 supplies power to each part of the mobile terminal device 1.

  Next, the printer 15 will be described. FIG. 4 is a cross-sectional view of a main part of the mobile terminal device 1 showing the printer 15 in detail. FIG. 5 is a perspective view of a main part of the mobile terminal device 1 showing the printer cover 7 in a fully opened state.

  As shown in FIG. 4, the printer 15 includes a printer head 31, a platen roller 32, a leaf spring 33, a drive motor 34, and a frame 35.

  The printer head 31 has a large number of heating elements arranged on a substrate. The platen roller 32 is disposed to face the printer head 31. The leaf spring 33 biases the printer head 31 so as to press it against the platen roller 32. As a result, the recording paper P sandwiched between the printer head 31 and the platen roller 32 is pressed against the printer head 31.

  The drive motor 34 rotationally drives the platen roller 32 via a speed reduction mechanism composed of a plurality of gears. The frame 35 supports the platen roller 32, the leaf spring 33, and the drive motor 34, and supports the printer head 31 so as to be movable in the front-rear direction.

  A paper discharge port 25 is provided in the gap between the upper end of the printer cover 7 and the housing 2.

  In the printer 15 configured as described above, the recording paper P drawn from the roll paper RP is sandwiched between the printer head 31 and the platen roller 32, and the platen roller 32 driven by the drive motor 34 rotates. Thus, the recording paper P is printed by the printer head 31 while being conveyed, and is discharged from the paper discharge port 25.

  A cutter 38 is provided in the vicinity of the paper discharge port 25, and the recording paper P discharged from the paper discharge port 25 can be cut out.

  The printer head 31 has a substantially flat plate shape and is arranged in a state slightly inclined with respect to the vertical direction. The drive motor 34 is disposed below the printer head 31. For this reason, the thickness of the entire printer 15 can be kept small. The printer 15 is arranged along the display panel 3. For this reason, the thickness of the whole housing | casing 2 can be restrained small.

  The recording paper P is discharged from the paper discharge port 25 on the upper surface of the mobile terminal device 1 with the print surface facing up. However, since the recording paper P is curled, the discharged recording is performed. The paper P is bent from the upper surface to the back side of the mobile terminal device 1 and it becomes difficult for the operator to see the printing surface of the recording paper P, but the posture of the mobile terminal device 1 can be freely changed. There is no particular hindrance.

  As shown in FIG. 5, an opening 12 for accommodating the roll paper RP is formed in the recording paper container 6 in the recording paper container 6 of the housing 2, and a printer cover 7 that closes the opening 12. Is connected to the housing 2 via a hinge part 41.

  The platen roller 32 is held by the printer cover 7. The rotation shaft 42 of the platen roller 32 is connected to left and right bearings 43 that rotatably support both left and right ends thereof, and a gear 44 that transmits the driving force of the drive motor 34 to the rotation shaft 42. A pair of platen roller holding portions 45 that hold the rotation shaft 42 of the platen roller 32 is formed on the printer cover 7 on the left and right.

  The opening 12 is formed in a range from the upper surface of the housing 2 to the back surface of the recording paper storage unit 6, and the recording paper storage unit 6 is largely opened by rotating the printer cover 7 around the hinge unit 41. Thus, the operation of accommodating the roll paper RP can be easily performed. Further, by rotating the printer cover 7, the platen roller 32 is separated from the printer head, so that it becomes easy to accommodate the roll paper RP and deal with paper jam (paper jam).

  A transparent window 46 is provided on the side surface of the recording paper storage unit 6. With this transparent window 46, the remaining amount of the roll paper RP in the recording paper storage unit 6 can be confirmed.

  In the recording paper storage unit 6, the roll paper RP is stored so that the central axis of the roll paper RP is parallel to the left-right direction, that is, the central axis of the platen roller 32.

  Next, the hinge part 41 is demonstrated. FIG. 6 is a perspective view of the main part of the printer cover 7. FIG. 7 is a perspective view of a main part of the housing 2.

  As shown in FIG. 6, the hinge part 41 is composed of a shaft part 51 formed in the printer cover 7 and a guide hole 52 formed in the housing 2 as shown in FIG. The guide hole 52 is fitted. The shaft portion 51 and the guide hole 52 are formed on the left and right sides of the printer cover 7 and the housing 2.

  The guide hole 52 is formed long in the vertical direction, and can move the shaft portion 51 in the vertical direction along the guide hole 52. Accordingly, the printer cover 7 can be slid in the vertical direction with respect to the housing 2.

  Further, as shown in FIG. 6, a rib 53 extending radially from the outer peripheral surface of the shaft portion 51 in a blade shape is formed in the vicinity of the shaft portion 51 formed on the printer cover 7. As shown in FIG. 7, the rotation of the rib 53 is restricted by abutting against the inner peripheral surface of the guide hole 52 formed in the housing 2.

  Further, a concave portion 55 is formed in the peripheral portion 54 of the guide hole 52 formed in the housing 2 so as to be one step lower than the side surface of the peripheral portion 54. The recess 55 forms a space in which the rib 53 rotates, and the shaft portion 51 can be rotated without the rib 53 interfering with the peripheral edge portion 54. Thereby, the printer cover 7 can be rotated with respect to the housing 2.

  Next, the opening / closing operation of the printer cover 7 will be described. FIG. 8 is a side view of the main part of the portable terminal device 1 showing the state transition when the printer cover 7 is opened and closed. FIG. 8A shows the fully closed state of the printer cover 7, and FIG. FIG. 8C shows the half-opened state of the printer cover 7, and FIG. 8C shows the fully-opened state of the printer cover 7.

  With such a configuration of the hinge portion 41, when the printer cover 7 is opened, the printer cover 7 can be slid upward from the fully closed state shown in FIG. As a result, as shown in FIG. 8B, the printer cover 7 is in a half-open state. Then, the printer cover 7 can be rotated from this half-open state. Thereby, as shown in FIG. 8C, the printer cover 7 is fully opened. Conversely, when the printer cover 7 is closed, the printer cover 7 can be rotated and slid.

  Thus, in this embodiment, when opening the printer cover 7, the printer cover 7 can be slid and rotated. For this reason, as shown in FIG. 4, the printer cover 7 can be opened without the platen roller 32 disposed between the roll paper RP and the printer head 31 interfering with the roll paper RP.

  Next, a structure for suppressing the rattling of the printer cover 7 during the sliding operation will be described. FIG. 9 is a cross-sectional view illustrating a state transition state of the hinge portion according to the open / close state of the printer cover 7.

  In the fully closed state of the printer cover 7 shown in FIG. 8A, the rib (rotation restricting portion) 53 extends in the sliding direction of the printer cover 7 as shown in FIG. 9A. Here, when the printer cover 7 is to be rotated, the rib 53 hits the inner peripheral surface of the guide hole 52 of the housing 2 and the rotation of the rib 53 is restricted. For this reason, the printer cover 7 cannot be rotated when the printer cover 7 is fully closed.

  In addition, since the rotation of the rib 53 is similarly restricted by the inner peripheral surface of the guide hole 52 from the fully closed state of the printer cover 7 shown in FIG. Can not be rotated.

  Further, as shown in FIG. 2, the left and right side edge portions 61 of the printer cover 7 and the left and right side edge portions 62 of the opening 12 in the housing 2 are formed straight along the sliding direction of the printer cover 7. ing. Thus, the side edge 61 of the printer cover 7 and the side edge 62 of the housing 2 are held in contact with each other during the sliding operation of the printer cover 7. For this reason, rattling of the printer cover 7 during the sliding operation can be suppressed. Accordingly, the printer cover 7 can be smoothly slid in conjunction with the rotation of the printer cover 7 being restricted during the sliding operation.

  Next, a structure for suppressing the rattling of the printer cover 7 during the rotation operation will be described.

  As shown in FIG. 7, a rib 65 protruding inward is provided on the inner peripheral surface of the guide hole 52. The rib 65 is provided so as to extend in the depth direction of the guide hole 52, that is, in the axial direction (hinge axis direction) of the shaft portion 51 of the printer cover 7 shown in FIG. 6.

  In the half-open state of the printer cover 7 shown in FIG. 8B and the fully-open state of the printer cover shown in FIG. 8C, as shown in FIG. 9B and FIG. The movement of the shaft portion 51 of the printer cover 7 is lightly restricted by the peripheral surface and the rib 65. Thereby, rattling of the printer cover 7 during rotation of the printer cover 7 can be prevented, and operability during rotation of the printer cover 7 can be improved.

  Further, when the shaft portion 51 of the printer cover 7 rides on the rib 65, it is possible to give a click feeling to the operator. Thus, when the printer cover 7 is slid from the fully closed state, the operator can confirm that the printer cover 7 has reached the end position in the sliding direction.

  Next, a structure for restricting the sliding operation of the printer cover 7 in the fully opened state will be described.

  As shown in FIG. 9C, the peripheral surface 54 of the guide hole 52 is formed with a regulating surface 67 against which the rib 53 of the printer cover 7 abuts when the printer cover 7 is fully opened. The restriction surface 67 makes it impossible for the rib 53 to move along the sliding direction of the printer cover 7. Thereby, the sliding operation of the printer cover 7 when the printer cover 7 is fully opened is restricted. For this reason, the operator cannot forcibly slide the printer cover 7 when the printer cover 7 is fully opened.

  Next, a structure for suppressing rattling of the printer cover 7 in the fully closed state will be described.

  As shown in FIG. 4, in the vicinity of the hinge portion 41, the edge portion 72 of the printer cover 7 that comes in contact with and separates from the edge portion 71 of the opening 12 in the housing 2 according to the sliding operation of the printer cover 7. Is formed with a claw-like portion 73 projecting inwardly. The claw-like portion 73 has a substantially L-shaped cross section so that the edge portion 71 of the housing 2 is fitted inside. Therefore, when the printer cover 7 is fully closed, the edge 72 of the printer cover 7 and the edge 71 of the housing 2 are fitted in an uneven cross-sectional shape, and the thickness of the printer cover 7 relative to the housing 2 is increased. Movement is regulated.

  Thereby, in order to smoothly perform the sliding operation of the printer cover 7, even when the hinge portion 41 has a relatively large play, the movement of the printer cover 7 with respect to the housing 2 is restricted in the fully closed state. Shaking of the printer cover 7 in the closed state can be suppressed.

  Next, a structure for restricting the rotation of the printer cover 7 in the fully closed state and protecting the gear 44 provided on the rotation shaft 42 of the platen roller 32 will be described.

  As shown in FIG. 5, on the outside of the platen roller holding portion 45 in the printer cover 7, protruding piece portions 81 protruding in a tongue shape so as to cover both end portions of the platen roller 32 are formed on both the left and right sides. The housing 2 is formed with concave portions 82 on both the left and right sides, into which the protruding portion 81 of the printer cover 7 is fitted when the printer cover 7 is fully closed. The projecting piece 81 and the recess 82 are formed so as to fit in the sliding direction of the printer cover 7. When the printer cover 7 is slid upward from the fully closed state shown in FIG. When the printer cover 7 is slid downward from the half-open state shown in FIG. 8B, the projecting piece 81 fits into the recess 82.

  Since the protrusion 81 fits into the recess 82 in this manner, the rotation of the printer cover 7 in the fully closed state is prevented, and the printer cover 7 cannot be forcibly rotated. You can avoid doing that. Further, as shown in FIG. 5, the gear piece 44 provided on the rotation shaft 42 of the platen roller 32 is protected by the projecting piece portion 81, and the operator's finger hits the gear 44 when opening and closing the printer cover 7. This prevents the gear 44 from being damaged.

  Next, the holding structure of the platen roller 32 will be described. FIG. 10 is a cross-sectional view of the main part of the mobile terminal device 1 showing the holding structure of the platen roller 32.

  A platen holder 91 for detachably holding the bearing 43 of the platen roller 32 is provided at the upper end of the frame 35 of the printer 15. The platen holder 91 has a recess 92 into which the bearing 43 of the platen roller 32 is fitted when the printer cover 7 is fully closed. In the vicinity of the recess 92, a lightening hole 93 is formed so that the inner peripheral portion of the recess 92 bends. Thereby, the bearing 43 of the platen roller 32 is fitted into the recess 92 by press fitting. The concave portion 92 is open at the top, and a convex portion 94 is formed on the rear side of the open portion of the concave portion 92.

  In the fully closed state of the printer cover 7 (see FIG. 8A), the concave portion 92 of the platen holder 91 holds the bearing 43 of the platen roller 32 with a relatively large pressure, so that the printer cover 7 is firmly closed to the fully closed state. The locked state is maintained. That is, the holding mechanism of the platen roller 32 becomes a lock mechanism that reliably holds the printer cover 7 in the fully closed state.

  When the printer cover 7 is slid upward from the fully closed state of the printer cover 7, the bearing 43 of the platen roller 32 is detached from the concave portion 92 of the platen holder 91, and the locked state is released. Conversely, when the printer cover 7 is slid downward from the half-opened state of the printer cover 7 (see FIG. 8B), the bearings 43 of the platen roller 32 are fitted into the recesses 92 of the platen holder 91 and become locked.

  When the bearing 43 of the platen roller 32 is fitted to or detached from the concave portion 92 of the platen holder 91, the bearing 43 of the platen roller 32 gets over the convex portion 94 of the platen holder 91. The platen roller holding portion 45 of the printer cover 7 holds the rotation shaft 42 of the platen roller 32 by a holding hole 96 that is long in the front-rear direction so as to allow movement in the front-rear direction. The platen roller 32 is slightly displaced forward against the urging force of the leaf spring 33 to be pressed. Thereby, the platen roller 32 can be smoothly moved during the sliding operation of the printer cover 7.

  As shown in FIG. 5, in the printer cover 7, the pair of leg portions 47 are separated from the peripheral wall portion 48 having a substantially arc-shaped cross section by recessing a portion between the pair of hinge portions 41. It is formed in an extended state. As a result, as shown in FIG. 2, it is possible to avoid the printer cover 7 from interfering with the camera 8 and the speaker 9 when the printer cover 7 is fully closed.

  Further, a planar lower wall portion 49 is formed between the pair of leg portions 47 in the printer cover 7, and the operator presses the lower wall portion 49 when the printer cover 7 is opened. The printer cover 7 can be slid.
