<Schematic configuration of printer>
The overall configuration of a printer (printing apparatus) 1 according to an embodiment of the present invention will be described with reference to FIGS. In the following description, the lower right direction in FIG. 1 is defined as right, the upper left direction is left, the upper right direction is rearward, the lower left direction is front, the upper direction is upper, and the lower direction is lower (in each figure). (See arrow illustration). In this example, the front-rear direction in the above definition corresponds to the horizontal direction described in each claim, the front corresponds to one side in the horizontal direction, and the rear corresponds to the other side in the horizontal direction.

  The printer 1 prints print data received from an external device (not shown) such as a PC terminal or a mobile phone on a roll paper S (print medium). The printer 1 can be driven using a battery (not shown) as a power source.

  The printer 1 includes a substantially box-shaped casing 100 that is made of, for example, a resin material and that forms an outer shell of the apparatus. The housing 100 includes a top cover 101 that constitutes the upper part of the apparatus outer shell and an under cover 102 that constitutes the lower part of the apparatus outer shell. The top cover 101 includes a fixed portion 101A and an opening / closing lid 101B.

  The end portion of the under cover 102 is provided with a pair of left and right insertion portions 102a. For example, the strap SP (see FIG. 11 described later) or the like is inserted into these insertion portions 102a, and is placed on the shoulder, neck, or waist belt, so that the operator can change the battery-driven printer 1 as described above. It can be easily carried and used in various places (including outdoors) (see FIG. 11 described later).

  A roll storage portion 161 (medium storage chamber) is provided below the opening / closing lid 101B of the top cover 101 (inside the housing 100) (see FIGS. 2 and 3). The roll storage unit 161 stores the roll paper S that is pivotally supported at both ends by the support member 162 so that the roll paper S can be continuously supplied from the roll storage unit 161. It has become. At this time, the opening / closing lid 101B is rotatably connected to the rear end portion of the under cover 102 via the hinge portion H, thereby opening the roll storage portion 161 to the outside, and the roll storage portion 161. It can be switched to the closed state to be accommodated inside. By opening the opening / closing lid 101B, the roll storage unit 161 can be exposed to the outside of the apparatus, and the roll paper S can be easily mounted or replaced.

  Further, a discharge port 107 for discharging the printed roll paper S is provided at a substantially central portion of the top cover 101 in the front-rear direction (in this example, the portion where the fixed portion 101A and the opening / closing lid 101B are attached). (See FIGS. 1 and 3). At this time, the discharge port 107 is provided so as to open toward one side along the vertical direction (in this example, upward).

  A platen roller 111 is rotatably supported at the front end 101C (see FIGS. 9 and 10 described later) of the opening / closing lid 101B. The platen roller 111 conveys the roll paper S by the rotation of a rotor (not shown) in the motor casing 21 being transmitted when the open / close lid 101B is in the closed state.

<Mechanical unit and surroundings>
On the other hand, a mechanical unit MU (print processing mechanism) including a main chassis member 150 is provided in the vicinity of the central portion in the front-rear direction inside the housing 100. The detailed structure of the mechanical unit MU is shown in FIG. As shown in FIG. 4, FIG. 2, and FIG. 3, in the mechanical unit MU, the head unit HU is disposed inside the main chassis member 150 so as to be swingable in the front-rear direction. The head unit HU is provided with an integrated thermal line head 112 and a heat sink 114 for cooling the heat generated by the thermal line head 112. The heat sink 114 is urged toward the platen roller 111 (that is, the rear side) by a plurality of (two in this example) coil springs 115 whose front side ends are supported by the main chassis member 150. Thus, when the open / close lid 101B is in the closed state, the thermal line head 112 contacts the platen roller 111 with a predetermined pressure contact force.

  As shown in FIG. 4, the mechanical unit MU includes a substantially cylindrical motor casing 21 that is an outer shell of the motor that generates a driving force for rotating the platen roller 111 on the left side of the main chassis member 150. And a gear mechanism 132 configured to be connected to the platen roller 111 in a closed state of the opening / closing lid 101B and transmitting the driving force of the motor to the platen roller 111. The motor casing 21 is provided below the discharge port 107 inside the housing 100 (see FIG. 3B described above). The drive of the drive motor is controlled by a control board 170 (see FIG. 3) arranged from the lower side of the mechanical unit MU to the rear of the housing 100. In this example, the control board 170 is extended in the horizontal direction in order to facilitate handling and assembling. The control board 170 controls the thermal line head 112 of the mechanical unit MU, the drive motor, and the like while using the power supplied from the battery.

  Further, the motor casing 21 is provided below the discharge port 107 inside the housing 100 (see FIG. 3B described above). For this reason, when the printer 1 is used in an environment where there is a possibility of being exposed to rainwater or other water, such as an outdoor environment or a water environment in a building, for example, splashes enter the inside of the housing 100 from the discharge port 107. However, the motor may be adversely affected. Therefore, in the present embodiment, a motor cover 31 that covers the motor casing 21 that is an outline of the drive motor is provided. The motor casing 21 has an axial direction in the left-right direction, and a motor shaft MA of the drive motor is provided so as to protrude from the motor casing 21 to the left side.

<Overview of printer operation>
In the above configuration, at the time of printing, print data is transmitted from an external device such as a PC terminal or a mobile phone to the printer 1 via wireless communication (or wired communication or infrared communication). Further, the roll paper S is fed out from the roll storage portion 161 by the rotation of the platen roller 111 based on the driving force of the motor. The fed roll paper S is guided to a pressure contact portion between the platen roller 111 and the thermal line head 112 by a guide member 120 provided below the discharge port 107. The thermal line head 112 performs printing in a desired mode on the roll paper S inserted between the thermal line head 112 and the platen roller 111 based on the print data. The printed roll paper S is discharged from the discharge port 107 to the outside of the housing 100. At this time, fixed teeth 160 are attached to the main chassis member 150 along the discharge port 107 inside the discharge port 107. The operator can manually cut the end portion of the roll paper S that has been printed as described above and discharged from the discharge port 107 using the fixed teeth 160.

  In addition, when the operator opens the opening / closing lid 101B and stores the roll paper S in the roll storage unit 161 as described above, in order to smoothly realize the above-described transport / printing operation during the subsequent printing operation. The leading end surplus portion of the roll paper S taken out from the roll storage portion 161 is passed between the thermal line head 112 of the mechanical unit MU and the platen roller 111 provided on the opening / closing lid 101B side, and the leading end surplus portion is further discharged to the discharge port. It is necessary to close the opening / closing lid 101 </ b> B after the 107 is inserted and exposed to the outside of the housing 100. Therefore, in the present embodiment, the front end portion 101C of the opening / closing lid 101B also serves as an edge portion on the rear side (in other words, the roll storage portion 161 side) of the discharge port 107.

  When a paper jam or the like occurs during printing, the platen roller 111 is released from the thermal line head 112 by opening the opening / closing lid 101B of the top cover 101, and the roll paper S can be easily pulled out. It becomes possible.

<Features of this embodiment>

  On the other hand, the second region Q inside the housing 100 has a second projecting region Q2 adjacent to the first projecting region P2 in the left-right direction so as to correspond to the projecting shape of the first projecting region P2. I have. At this time, the second region Q includes a second base region portion Q1 disposed so as to be retracted closer to the roll storage portion 161 than the second projecting region portion Q2, and the second base region portion Q1 is the first projecting portion. It arrange | positions facing the roll accommodating part 161 side (in other words, back side) of the area | region part P2. Note that the left and right end portions of the mechanical unit MU are inserted and disposed in the two left and right second projecting region portions Q2. That is, the motor casing 21 and the gear mechanism 132 (see FIG. 4), which are the left end portion of the mechanical unit MU, are inserted and disposed in the left second projecting region Q2. On the other hand, a release mechanism (detailed illustration is omitted), which is the right end portion of the mechanical unit MU, is inserted and disposed in the second protruding region Q2 on the right side.

<Specific configuration of partition wall>
In the present embodiment, the partition wall R corresponds to the boundary between the first protruding region portion P2 of the first region P and the second protruding region portion Q2 of the second region Q, and the first partition portion R1 and The second partition portion R2 and the third partition portion R3 are provided. The first partition portion R1 extends in the left-right direction so as to partition the first projecting region portion P2 and the second base region portion Q1, is located at the projecting end of the projecting substrate portion 170a, and is the main part of the mechanical unit MU. It arrange | positions so that it may go under the chassis member 150. FIG. The second partition portion R2 is positioned in front of the first partition portion R1, and extends along the left-right direction so as to partition the second projecting region portion Q2 and the first base region portion P1. The third partition portion R3 extends along the front-rear direction so as to connect the first partition portion R1 and the second partition portion R2 and partition the first projecting region portion P2 and the second projecting region portion Q2.

That is, while the thermal line head 112 and the platen roller 111 are provided above the partition wall R, the drive motor is not above the partition wall R but on the side of the second partition portion R2 and the third partition portion R3. It arrange | positions in the protrusion area | region part Q2.

<Sensor for open / close detection>
Here, in the printer 1 of the present embodiment, a sensor (movement detection sensor LS) for detecting the opening / closing operation of the opening / closing lid 101B is provided in the same manner as this type of opening / closing lid type printer. However, when this sensor is provided in the second region Q on the same side as the opening / closing lid 101B, there is a concern about waterproofness to the sensor as described above.

  Therefore, in the present embodiment, a movement detection sensor LS such as a limit switch is provided in the first region P opposite to the opening / closing lid 101B (FIGS. 5A, 5B, 6A). ), See FIG. 6B). Instead of directly detecting the movement of the opening / closing lid 101B by the movement detection sensor LS, the movement of the opening / closing lid 101B on the second region Q side is determined by, for example, a seesaw type or lever lever type movement transmission mechanism 200 (described later). 8) is mechanically transmitted to the first region P side, and this is indirectly detected by the movement detection sensor LS. Hereinafter, the details will be described in order.

<Detailed configuration and operation of the movement detection sensor>
As shown in FIG. 8, the movement detection sensor LS is disposed at the boundary position between the first region P and the second region Q so as to straddle the first region P and the second region Q as described above. Of the mechanical unit MU on the first region P side. The movement transmission mechanism 200 for transmitting the operation of the opening / closing lid 101B to the movement detection sensor LS has a swing shaft 201 with respect to the side surface of the main chassis member 150, as shown in FIGS. And is provided across the first region P and the second region Q in a state where the first region P and the second region Q are supported. The movement transmission mechanism 200 includes a movement input unit 202 positioned on the rear side (that is, the second region Q side) of the mechanical unit MU and the partition wall R, and the front side of the mechanical unit MU and the partition wall R (that is, the first region P). A wide rectangular plate-like movement output unit 203 located on the side).

  Here, as described above, the opening / closing lid 101B is rotatable with respect to the under cover 102 via the hinge portion H provided at the base end. Then, both end shafts of the platen roller 111 are supported by a cylindrical bearing 111A protruding from the opening / closing lid 101B on the lower surface side of the front end of the opening / closing lid 101B. When the opening / closing lid 101B is rotated in the closing direction from the open position (see FIG. 9) for opening the roll storage portion 161 to the closed position (see FIG. 10), the bearing 111A is moved to the main chassis member 150. Are fitted into fitting recesses 111B provided on the upper left and right side surfaces (see FIG. 10). At this time, the movement input unit 202 of the movement transmission mechanism 200 is arranged so as to be adjacent to the fitting recess 111B. When the bearing 111A is fitted into the fitting recess 111B, the movement input unit 202 is pushed downward by the bearing 111A, and the movement transmission mechanism 200 swings counterclockwise about the swing shaft 201. To do.

  On the other hand, at this time, the movement detection sensor LS is disposed on the left side surface of the main chassis member 150 above the movement output unit 203 of the movement transmission mechanism 200. Specifically, the movement detection sensor LS is provided with a switch lever LS1 that protrudes obliquely downward toward the first region P, and the movement output unit 203 is disposed opposite to the lower side of the switch lever LS1. ing.

  That is, when the opening / closing lid 101B is closed as described above on the second region Q side, the movement input unit 202 comes into contact with the opening / closing lid 101B that is lowered to the closed position. As a result, the movement input unit 202 descends and the movement transmission mechanism 200 swings counterclockwise around the swing shaft 201. By this swinging, the downward movement of the movement input unit 202 is mechanically transmitted to the movement output unit 203 located in the first region P, and the movement output unit 203 moves upward to push up the switch lever LS1. That is, the downward movement of the movement input unit 202 is converted into the upward movement of the movement output unit 203 and output. Thereby, the movement detection sensor LS is turned on, and it is detected that the open / close lid 101B is in the closed state.

  As described above, in the printer 1 according to the present embodiment, the opening / closing operation of the opening / closing lid 101B in the second region Q in the externally open state is transmitted to the first region P side via the movement transmission mechanism 200. The movement is detected by the movement detection sensor LS. Thereby, opening / closing detection can be performed while ensuring waterproofness to the movement detection sensor LS. As a result, the open / close detection performance of the open / close lid 101B can be maintained satisfactorily.

  In the present embodiment, in particular, by providing the mechanical unit MU on the upper part of the partition wall R, the splash of splashes from the second region Q side to the first region P due to the cooperation of the mechanical unit MU and the partition wall R. Can be sufficiently shielded to ensure waterproofness to the movement detection sensor LS.

  In the present embodiment, in particular, in the movement transmission mechanism 200, the movement output unit 203 converts the downward movement of the movement input unit 202 accompanying the lowering of the opening / closing lid 101B and outputs it as an upward movement. The movement detection sensor LS is located above the movement output unit 203 and detects the upward movement of the movement output unit 203. As a result, even if it is assumed that a splash has entered from the movement input unit 202 in the second region Q and has traveled along the surface of the movement transmission mechanism 200 and appears from the movement output unit 203 to the first region P, the movement detection is performed. Since the sensor LS is located above the movement output unit 203, the appearing splash does not reach the movement detection sensor LS. Therefore, it is possible to prevent the movement detection sensor LS from being exposed to splashes.

  Furthermore, as shown in FIG. 11, the operator U hangs the printer 1 in such a posture that the control board side 170 is up and the roll storage unit 161 is down using the strap SP inserted through the insertion portion 102 a and hanging from the shoulder or waist. In use, even if the entire printer 1 is slightly inclined, the positional relationship in which the movement detection sensor LS is upward and the movement output unit 203 is downward is large (for example, unless the top of the printer 1 is turned upside down). It will not change. Therefore, even in the usage mode of the operator U as described above, the movement detection sensor LS can be prevented from being exposed to splashes.

  In the present embodiment, in particular, the end portion 101C of the opening / closing lid 101B and the edge portion of the discharge port 107 are matched. Thus, after the opening / closing lid 101B is opened to expose the leading end surplus portion of the roll paper S, the roll paper S can be easily inserted into the discharge port 107 only by closing the opening / closing lid 101B. it can. As a result, the preparatory operation before the start of printing by the operator can be simplified, and convenience can be improved.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
