DETAILED DESCRIPTION OF THE INVENTION

[0012] An embodiment of a printer according to the present invention will be described below.

[0013] (1) Printer configuration A printer 1 according to an embodiment will be described below with reference to FIGS. 1A, 1B, and 2. FIG.

[0014] Fig. 1A is a perspective view showing the front, top, and left side of the printer 1 according to the embodiment with the printer cover 3 closed. Fig. 1B is a perspective view showing the front, top, and left side of the printer 1 according to the embodiment with the printer cover 3 open. Fig. 2 is a perspective view showing the back, top, and left side of the printer 1 according to the embodiment of the present invention.

[0015] As shown in Figures 1A, 1B and 2, the printer 1 of this embodiment comprises a main body case 2, a printer cover 3, a display panel 4, a platen roller 10 and a thermal head 28 (an example of the "print head" of the present invention).

[0016] For example, as can be seen in FIG. 1A, the bottom surface of the printer 1 is roughly rectangular, and the direction along its long side is defined as the front-to-rear direction. That is, the side where the display panel 4 is provided is defined as the front (FR), and the opposite side, the printer cover side, is defined as the rear (RR). Based on this front-to-rear direction, the right side (RH), left side (LH), top side (UP), and bottom side (LO) are defined. In the following description, the right side (RH) or left side (LH) direction will be referred to as the horizontal direction, and the top side (UP) or bottom side (LO) direction will be referred to as the vertical direction.

[0017] As shown in Figure 2, the interior of the printer 1 may be provided with a roll body storage chamber 9 for storing a roll body 355 in which continuous paper (an example of the "printing medium" of the present invention) 353 is wound in a roll shape, and the main body case 2 may be formed with an internal bottom surface 2a (see Figure 3) for placing the roll body 355.

[0018] The printer cover 3 is a cover that opens or closes the inside of the printer 1. A hinge 8 including a hinge shaft 81 for supporting the printer cover 3 rotatably relative to the main body case 2 is provided at the rear end of the printer cover 3. The display panel 4 provides an input / output interface for the user, and is, for example, a liquid crystal display panel equipped with a touch panel function.

[0019] As shown in Fig. 2, a platen roller 10 is supported so as to be rotatable in both forward and reverse directions at the leading end of the printer cover 3, opposite the hinge 8. When the printer cover 3 is closed, as shown in Fig. 3, the platen roller 10 is positioned behind the thermal head 28.

[0020] The platen roller 10 is a conveying means that conveys the continuous paper 353 pulled out from the roll 355 housed in the roll housing chamber 9 while being held by a pair of roll guides 6a, and is formed to extend in the width direction of the roll 355. The platen roller 10 is mechanically coupled to and driven by a stepping motor (not shown) or the like.

[0021] The thermal head 28 is a printing means that prints information such as characters, symbols, figures, or barcodes on the continuous paper 353 drawn from the roll 355. As shown in FIG. 3, when the printer cover 3 is closed, the printing surface of the thermal head 28 faces the paper feed path of the continuous paper 353 and faces the platen roller 10. On the printing surface of the thermal head 28, multiple heating resistors (not shown) that generate heat when electricity is applied are arranged in a row along the width direction of the continuous paper 353. The thermal head 28 is connected to a circuit board (not shown) that transmits print signals to the thermal head 28. A coil spring 157 is provided on the rear side of the thermal head 28 as a biasing member that applies a biasing force to the thermal head 28 .

[0022] When printing is being performed with the printer cover 3 closed, the continuous paper 353 is conveyed by the platen roller 10 and is sandwiched between the platen roller 10 and the thermal head 28. At this time, the thermal head 28 is pressed against the platen roller 10 by the above-mentioned biasing force, thereby generating a head pressure suitable for printing.

[0023] (2) Printer cover The printer cover 3 can be opened and closed about the rotation axis of the hinge 8 between a closed position as shown in Fig. 4 and an open position at the maximum rotation angle as shown in Fig. 5. Here, the maximum rotation angle refers to the angle at which the cover-side cushioning member 151 provided on the rear surface 123 of the printer cover 3 abuts against the main body-side cushioning member 141 provided on the rear surface 121 of the main body case 2, preventing the printer cover 3 from rotating any further.

[0024] (3) Battery As shown in FIG. 6, a battery 501 that serves as the power source for the printer 1 is housed in a battery housing portion 401 (see FIG. 7) provided on the bottom surface 131 of the main body case. The configuration of the battery will be described with reference to FIGS. 8, 9, 10, 11 and 12.

[0025] As will be described later, the battery 501 is first placed against the rear side 413 (see Figure 7) of the battery storage section 401 by a pair of edge portions 561 (see Figures 10 and 12) located at the boundary between the back surface 555 and a pair of front sleeve surfaces 503, and then accommodated in the battery storage section 401 by a movement including translational and rotational movements, with the side corresponding to the rear front edge portions 561 being the front side (referred to as the "first battery side" in this invention).

[0026] 9 and 10, the front side of the battery 501 is provided with a pair of front sleeve surfaces 503, a front body surface 505, a front beam portion 507, a front shoulder portion 509, and a front engagement groove 511. The pair of front sleeve surfaces 503 are provided on both sides of the front torso surface 505, each including the right end or the left end of the front side surface.

[0027] The pair of front sleeve surfaces 503 are perpendicular to the surface 557. The pair of front sleeve surfaces 503 are also perpendicular to the left side surface 551 and the right side surface 553, respectively. The pair of front sleeve surfaces 503 are perpendicular to the surface 557 because the pair of front sleeve surfaces 503 are used as reference surfaces in the longitudinal direction of the battery 501 . The front sleeve surface 503 extends from the front surface 557 to the back surface 555 in the height direction. A front beam portion 507 is provided slightly below the upper end of the front side surface, and the front body surface 505 extends from the back surface 555 to the front beam portion 507. The front body surface 505 is recessed toward the inside of the battery 501 relative to the front sleeve surface 503 and the front beam portion 507 . A pair of front shoulders 509 are provided on the upper portion of the front beam 507, and a front secondary beam 510 is sandwiched between them and spaced apart from each other. When the pair of front shoulder portions 509 and the front secondary beam portion 510 are viewed together from the front, they have a concave shape with a recessed upper center portion. The front engagement groove 511 is formed to correspond to the concave shape when the pair of front shoulder portions 509 and the front secondary beam portion 510 are viewed together. The front engagement groove 511 is provided in the center of the front upper edge of the battery 501, and is a rectangular cutout when viewed in cross section.

[0028] Referring to Figures 8 and 11, the rear side of the battery 501 (referred to as the "second battery side" in this invention) is provided with a pair of vertical rear side surfaces 521, a pair of inclined rear side surfaces 523, a pair of rear groove portions 525, and a hook portion 527.

[0029] The pair of vertical rear side surfaces 521 are both approximately perpendicular to the surface 557. The pair of inclined rear side surfaces 523 are both inclined so as to form an acute angle with the surface 557 that is slightly (approximately 10 degrees) less than a right angle when viewed from the side.

[0030] The pair of vertical rear side surfaces 521 and the pair of inclined rear side surfaces 523 are connected in the vertical direction, and are arranged so that they sandwich the pair of rear groove portions 525 and hook portions 527 on both sides and each include the right end portion or the left end portion of the rear side surface.

[0031] As shown in FIGS. 8, 11, and 15, when viewed from the side, the hook portion 527 is provided at a position recessed (inward) from the pair of vertical rear side surfaces 521 and the pair of inclined rear side surfaces 523. Therefore, the hook portion 527 is protected from impact when the battery 501 is dropped by the pair of vertical rear side surfaces 521 and the pair of inclined rear side surfaces 523. In other words, even if the battery 501 is dropped in a position that causes the hook portion 527 to hit a floor or the like, any portion of the pair of vertical rear side surfaces 521 or the pair of inclined rear side surfaces 523 will hit the floor or the like, and the hook portion 527, which is provided at a position recessed from the pair of vertical rear side surfaces 521 or the pair of inclined rear side surfaces 523, will not hit the floor or the like. In the worst case scenario, any portion of the pair of vertical rear side surfaces 521 or the pair of inclined rear side surfaces 523 will hit the floor or the like before the hook portion 527. Therefore, even if the battery 501 hits a floor or the like, damage to the hook portion 527 can be avoided.

[0032] Each of the pair of rear grooves 525 is provided between the corresponding side of the hook portion 527 and the vertical rear side surface 521 or the inclined rear side surface 523. A hook back gap 541 is provided between the back side of the hook portion 527 and the battery 501 body. The pair of rear grooves 525 communicate with the hook back gap 541. This allows the hook portion 527, except for its bottom, to be isolated from the rest of the battery and form a columnar shape. The case of the battery 501, including the hook portion 527, is made of resin. Therefore, the hook portion 527 is flexible.

[0033] The hook portion 527 has a pair of hook shoulders 529 , a hook neck 531 , a pair of hook shoulder lower inclined surfaces 533 , a hook top 535 , a hook body 537 and a hook rib 539 . A plurality of hook ribs 539 are provided near the lower end of the hook portion 527 . The hook body 537 is provided on a plurality of hook ribs 539 . A pair of hook shoulders 529 are provided on both sides of the top of the hook portion 527 . The hook neck 531 is sandwiched between a pair of hook shoulders 529 in the width direction and extends above the pair of hook shoulders 529 . The pair of hook shoulder lower inclined surfaces 533 are provided in an area above the hook body 537 below the hook shoulder 529, and face obliquely downward and rearward. The hook top 535 is located at the upper end of the hook neck 531 and has a canopy shape that extends rearward of the battery 501 . The battery 501 has a front surface 557, a back surface 555, a right side surface 553, and a left side surface 551. These surfaces 557, 555, 553, and 551 form a rectangular parallelepiped when viewed from the front of the battery 501.

[0034] 10 and 12, as already described, there are a pair of marginal edges 561 at the boundary between the back surface 555 and the pair of front sleeve surfaces 503. In addition, there is a marginal edge 562 at the boundary between the back surface 555 and the front torso surface 505. 11 and 12, a pair of marginal edges 563 are present at the boundary between the rear surface 555 and the pair of inclined rear side surfaces 523.

[0035] 12, electrode protrusion 587 is provided at a position closer to the front of back surface 555. Electrode protrusion 587 protrudes outward beyond back surface 555 as shown in FIG. Inside the electrode protrusion 587, a negative electrode 581, a plurality of control signal electrodes 585, and a positive electrode 583 are arranged in this order from the left. Furthermore, the negative electrode 581, the plurality of control signal electrodes 585, and the positive electrode 583 are aligned at the same position in the front-to-rear direction.

[0036] A waterproof annular packing portion 589 is provided around the electrode convex portion 587. The waterproof annular packing portion 589 is made of a material such as foamed resin or elastomer, for example.

[0037] Electrode surface 591 of each of negative electrode 581, multiple control signal electrodes 585 and positive electrode 583 is a rectangular flat surface, and is located slightly closer to the main body (recessed position) than the surface of electrode protrusion 587.

[0038] (4) Battery compartment Next, the configuration of the battery receptacle 401 will be described with reference to FIG.

[0039] The battery storage section 401 is surrounded by a battery enclosing surface including a front side surface 403 at the front, a pair of vertical rear side surfaces 405 at the rear, a pair of inclined rear side surfaces 407 and a hook receiving side surface 419 (corresponding to the "planar convex portion" of the present invention), a left side surface 409 at the left side, a right side surface 411 at the right side, and a rear side surface 413 at the rear.

[0040] Here, the front side surface 403 corresponds to the "first side surface" as defined in the present invention. The pair of vertical rear side surfaces 405, the pair of inclined rear side surfaces 407, and the hook receiving side surface 419 all or partly correspond to the "second side surface" as defined in the present invention. Furthermore, the hook receiving side surface 419 corresponds to the "surface convex portion" as defined in the present invention. Furthermore, the battery storage section 401 is open to the bottom surface 131 of the main body case (the main body case bottom surface 131 has an opening 423).

[0041] 7 and 15, front side surface 403 is perpendicular to main body case bottom surface 131 (an example of a predetermined surface). Furthermore, a pair of vertical rear side surfaces 405 and a pair of inclined rear side surfaces 407 are provided so as to sandwich hook receiving side surface 419 from both sides and connect to left side surface 409 or right side surface 411. As mentioned above, since the pair of front sleeve surfaces 503 are perpendicular to the surface 557, the battery 501 can be accurately and easily accommodated in the battery accommodating section 401 by abutting the pair of front sleeve surfaces 503, which are the longitudinal reference surfaces of the battery 501, against the front side surface 403. It should be noted that the front side surface 403 does not have to be perpendicular to the main body case bottom surface 131. Even in this case, by adjusting the inclination angle of the pair of front sleeve surfaces 503 relative to the surface 557 in accordance with the front side surface 403, the battery accommodating section 401 can be configured to accommodate the battery 501 in the same posture.

[0042] The vertical rear side surface 405 and the inclined rear side surface 407 on each side are connected. The vertical rear side surface 405 on each side is almost perpendicular to the main body case bottom surface 131. The inclined rear side surface 407 on each side is inclined at about 10 degrees toward the front as it approaches the back side surface 413. The hook receiving side surface 419 is a flat surface that protrudes forward relative to the vertical rear side surface 405 and the inclined rear side surface 407 and is approximately parallel to the inclined rear side surface 407. Left side surface 409 and right side surface 411 are substantially perpendicular to main body case bottom surface 131. Back side surface 413 is substantially parallel to main body case bottom surface 131.

[0043] Front protrusion 415 (corresponding to the "first protrusion" of the present invention) is provided so as to protrude rearward in the center of the boundary edge between main body case bottom 131 and front side surface 403 (excluding the areas near both ends), and has a surface that forms part of main body case bottom 131, as shown in Fig. 13. Furthermore, the widths and positions of front protrusion 415 in the front-rear, up-down, and lateral directions are determined so that front engagement groove 511 of battery 501 engages with front protrusion 415 when battery 501 is accommodated in battery accommodation section 401.

[0044] 13 and 7, the pair of rear protrusions 417 (corresponding to the "second protrusions" of the present invention) are each provided so as to protrude forward from a position adjacent to the hook receiving side surface 419 on the boundary edge between the main body case bottom surface 131 and the pair of vertical rear side surfaces 405, and have a surface that forms part of the main body case bottom surface 131. The widths and positions of the pair of rear protrusions 417 in the front-rear, up-down, and lateral directions are determined so that when the battery 501 is accommodated in the battery accommodation section 401, the surfaces of the pair of rear protrusions 417 that face the inner side surface 413 will abut against the pair of hook shoulders 529 of the battery 501, respectively.

[0045] Therefore, in the direction along the boundary between the rear side surface 413 and the front side surface 403, the range in which the front protrusion 415 is located and the range in which the pair of rear protrusions 417 are located are partially different. Finger recess 421 is provided at the rear center of battery storage section 401 on main body case bottom surface 131.

[0046] The depth, front-to-back and left-to-right widths and position of finger recess 421 are determined so that when battery 501 is accommodated in battery storage section 401, the back surface (the surface facing the same direction as back surface 555) of hook top 535 of battery 501 abuts against the front edge of finger recess 421, and further so that a person's finger can be inserted into finger recess 421 at that time. A terminal recess 471 is provided near the center in the width direction of the rear side surface 413 near the front. In the terminal recess 471, a negative terminal installation portion 461, a control signal terminal installation portion 465, and a positive terminal installation portion 463 are arranged in this order from the left. A plurality of negative terminals 441 are provided in the negative terminal installation portion 461 . A plurality of control signal terminals 449 are provided in the control signal terminal installation section 465 . The positive terminal installation portion 463 is provided with a plurality of positive terminals 445 .

[0047] 7 and 21, each of the plurality of negative terminals 441, the plurality of control signal terminals 449, and the plurality of positive terminals 445 (hereinafter referred to as "each terminal 441, 449, 445") has a pin shape that is bent in a mountain shape. The mountain shape is raised in the front-to-rear direction so as to have apexes 443, 451, 447 that point from the rear side surface 413 toward the main body case bottom surface 131. The mountain shape also has an inclined portion that approaches the rear side surface 413 from apexes 443, 451, 447 toward the rear end (the end on the second side surface side).

[0048] The terminals 441, 449, 445 are provided so that their tops 443, 451, 447 do not protrude further toward the opening 423 (toward the main body case bottom surface 131) than the rear side surface 413. Therefore, as will be described later, when the battery 501 is accommodated in the battery accommodating section 401, if the pair of edge portions 561 of the battery 501 translates while contacting the rear side surface 413, the pair of edge portions 561 of the battery 501 are prevented from coming into contact with the terminals 441, 449, 445. Note that when the battery 501 is accommodated in the battery accommodating section 401, the edge portion 562 is spaced apart from the rear side surface 413, which also prevents the edge portion 562 from coming into contact with the terminals 441, 449, 445.

[0049] Each negative terminal 441 is disposed forward of each control signal terminal 449 and each positive terminal 445. Therefore, on the back side surface 413, the distance from the front side surface 403 to each negative terminal 441 is shorter than the distance from the front side surface 403 to each control signal terminal 449 and each positive terminal 445.

[0050] A waterproof annular protrusion 473 is provided in an area adjacent to the outer side of the terminal recess 471. The waterproof annular protrusion 473 is provided so as to come into contact with the waterproof annular packing 589 when the battery 501 is housed in the battery housing portion 401. This ensures waterproofing in the area surrounded by the waterproof annular protrusion 473 and the waterproof annular packing 589 (the area sandwiched between the surface of the terminal recess 471 and the surface of the electrode protrusion 587).

[0051] A convexity-forming recess 475 is formed around the annular waterproof convexity 473 so that the annular waterproof convexity 473 is formed between the terminal recess 471 and the convexity-forming recess 475. Therefore, the convexity-forming recess 475 is formed on the outer periphery of the annular waterproof convexity 473. Such a convexity-forming recess 475 may be divided into multiple parts with gaps between them. In such a case, the annular waterproof convexity 473 is also divided into multiple parts with gaps between them.

[0052] As shown in Figure 13, when the battery 501 is accommodated in the battery accommodating section 401, the front protrusion 415 engages with the front engagement groove 511 (see Figure 9), and the surfaces of the pair of rear protrusions 417 facing the rear side surface 413 abut against the pair of hook shoulders 529 (see Figure 8) of the battery 501, thereby preventing the battery 501 from jumping out of the battery accommodating section 401.

[0053] 14, when battery 501 is housed in battery housing portion 401, the height of battery 501 and the depth of battery housing portion 401 are adjusted so that the height of surface 557 of battery 501 matches the height of main body case bottom surface 131. In this state, surface 557 of battery 501 and main body case bottom surface 131 are on the same plane. Therefore, surface 557 of battery 501 housed in battery housing portion 401 is an exposed surface and forms part of main body case bottom surface 131. Therefore, a cover for covering battery 501 housed in battery housing portion 401 is not necessary.

[0054] (5) Operation when inserting the battery into the battery compartment Next, the operation when the battery 501 is accommodated in the battery accommodating portion 401 will be described with reference to FIGS.

[0055] When the battery 501 is housed in the battery housing portion 401, the printer 1 is placed on a table or the like with the main body case bottom surface 131 facing upward, as shown in FIGS.

[0056] 15 , the front side of the battery 501 is inserted into the battery holding portion 401 until the vicinity of the edge portion 561 of the battery 501 abuts against the rear side surface 413 of the battery holding portion 401. At this time, the battery 501 is inclined so that the rear side of the battery 501 cannot be inserted into the battery holding portion 401.

[0057] 16, the rear side portion of the battery 501 is lowered until a pair of edge portions 563 of the battery 501 abuts against a pair of vertical rear side surfaces 405 (or a pair of inclined rear side surfaces 523) of the battery holding portion 401. When being lowered, the edge portions 561 of the battery 501 move toward the front side surface 403 while remaining in contact with the rear side surface 413.

[0058] 17, 18, and 19, the rear portion of the battery 501 is lowered so that the pair of edge portions 563 or the pair of inclined rear side surfaces 523 of the battery 501 fall with or without contacting the pair of inclined rear side surfaces 407 or the pair of vertical rear side surfaces 405 of the battery holding portion 401. When being lowered, the edge portions 561 of the battery 501 gradually move toward the front side surface 403 while remaining in contact with the rear side surface 413.

[0059] Therefore, when the rear portion of the battery 501 lowers, the battery 501 moves in a manner that includes a translational movement along the rear surface 413 of the edge portion 561 of the battery 501 and a rotational movement of the battery 501 with the edge portion 561 of the battery 501 as the fulcrum.

[0060] During this downward movement, hook body 537 abuts against rear protrusion 417 of battery housing 401, causing hook portion 527 to bend toward the main body of battery 501. The hook portion before bending is indicated by 527R, and the hook portion after bending is indicated by 527. After hook body 537 passes rear protrusion 417, hook shoulder lower inclined surface 533 abuts against rear protrusion 417, causing the bending of hook portion 527 to rapidly increase.

[0061] As shown in Figure 20, the movement of the battery 501 ends when the entire back surface 555 of the battery 501 abuts against the rear side surface 413 of the battery storage section 401, and the battery 501 becomes housed in the battery storage section 401, as shown in Figure 13.

[0062] At this time, the hook shoulder lower inclined surface 533 climbs over the rear protrusion portion 417, and as described above, the surfaces of the pair of rear protrusion portions 417 facing the rear side surface 413 abut against the pair of hook shoulder portions 529 of the battery 501.

[0063] In addition, the front beam portion 507 of the battery 501 abuts against the rib 404 provided on the front side surface 403 of the battery accommodating portion 401, the pair of vertical rear side surfaces 521 of the battery 501 abuts against the pair of vertical rear side surfaces 405 of the battery accommodating portion 401, the pair of inclined rear side surfaces 523 of the battery 501 abuts against the pair of inclined rear side surfaces 407 of the battery accommodating portion 401, the left side surface 551 of the battery 501 abuts against the left side surface 409 of the battery accommodating portion 401, and the right side surface 553 of the battery 501 abuts against the right side surface 411 of the battery accommodating portion 401, so that the battery 501 is accommodated in the battery accommodating portion 401 so that it cannot move in the front-to-back or left-to-right directions.

[0064] Next, when battery 501 is in the inclined position shown in FIG. 18, electrode surface 591 of negative electrode 581 of battery 501 and tops 443 of the corresponding negative terminals 441 of battery accommodating section 401, electrode surfaces 591 of the corresponding control signal electrodes 585 of battery 501 and tops 451 of the corresponding control signal terminals 449 of battery accommodating section 401, and electrode surface 591 of positive electrode 583 of battery 501 and tops 447 of the corresponding positive terminals 445 of battery accommodating section 401 may have an arrangement relationship as shown in FIG. 21.

[0065] In FIG. 21, the position of the top 443 of each negative terminal 441 in the front-rear direction is y1, and the position of the tops 447, 451 of each positive terminal 445 and each control signal terminal 449 in the front-rear direction (FR-RR direction) is y2.

[0066] The height z1 of the electrode surface 591 of the negative electrode 581 at the position y1 coincides with the height z1 of the surface of the top portion 443 of each negative terminal 441, and therefore the negative electrode 581 comes into contact with each negative terminal 441.

[0067] On the other hand, the height z2 at position y2 of the electrode surface 591 of the positive electrode 583 is below (LO side) (upper side in Figure 21) the height z1 of the surface of the top 447 of each positive terminal 445, so the positive electrode 583 does not contact each positive terminal 445.

[0068] Similarly, the height z2 of the electrode surface 591 of the control signal electrode 585 at position y2 is below (LO side) (upper side in Figure 21) the height z1 of the surface of the top 451 of each control signal terminal 449, so the control signal electrode 585 does not contact each control signal terminal 449.

[0069] In other words, when the battery 501 has a specific inclined posture as shown in Figures 18 and 21, the negative electrode 581 contacts each negative terminal 441, but the positive electrode 583 does not contact each positive terminal 445, and the control signal electrode 585 does not contact each control signal terminal 449.

[0070] In the process of accommodating the battery 501 in the battery accommodating section 401, before the battery 501 assumes the above-mentioned posture, the battery 501 is further inclined when viewed from the side (the back surface 555 is further inclined relative to the rear surface 413), but at this time, the negative electrode 581 is not in contact with each negative terminal 441.

[0071] Furthermore, in the process of accommodating battery 501 in battery accommodating section 401, after battery 501 has assumed the above-mentioned posture, the inclination of battery 501 becomes even less when viewed from the side (the inclination of back surface 555 relative to rear surface 413 becomes less), but at a certain inclination angle, in addition to negative electrode 581 contacting each negative terminal 441, positive electrode 583 contacts each positive terminal 445, and control signal electrode 585 contacts each control signal terminal 449.

[0072] Therefore, in the entire process of accommodating the battery 501 in the battery accommodating section 401, first, contact is made between the negative electrode 581 and each negative terminal 441, then contact is made between the positive electrode 583 and each positive terminal 445, and at the same time, contact is made between the control signal electrode 585 and each control signal terminal 449.

[0073] A contact order in which the positive electrode 583 comes into contact with each positive terminal 445 and then the negative electrode 581 comes into contact with each negative terminal 441 can cause damage to the printer circuitry. This can be avoided by the combination of the battery 501 and battery housing 401 of this embodiment.

[0074] Furthermore, a contact order in which control signal electrode 585 comes into contact with each control signal terminal 449 and then negative electrode 581 comes into contact with each negative terminal 441 can also cause damage to the printer circuitry. This can be avoided by the combination of battery 501 and battery housing 401 of this embodiment.

[0075] If an attempt is made to store battery 501 in battery storage section 401 with battery 501 upside down, edge portion 567 (see Figure 8) near the boundary between surface 557 and the pair of vertical rear side surfaces 521 will interfere with the pair of rear protrusions 417, making it impossible to store battery 501.

[0076] Furthermore, if an attempt is made to store the battery 501 in the battery storage section 401 with the front-to-back direction of the battery 501 reversed, the peripheral portion 561 will interfere with the pair of rear protrusions 417, making it impossible to store the battery 501.

[0077] Furthermore, if an attempt is made to store the battery 501 in the battery storage section 401 with the top-bottom and front-to-back directions of the battery 501 reversed, the pair of edge portions 565 (see Figure 9) near the boundary between the surface 557 and the pair of front sleeve surfaces 503 will interfere with the pair of rear protrusion portions 417, making it impossible to store the battery 501. That is, the battery 501 can be housed in the battery housing portion 401 only in the correct orientation in both the up-down direction and the front-rear direction.

[0078] To remove battery 501 housed in battery housing 401, the user first inserts his or her fingers into finger recess 421 and bends hook top 535 toward the main body, then inserts his or her fingers between finger recess 421 and hook top 535 and lifts hook top 535. Then, for example, the user pinches left side surface 551 and right side surface 553 of battery 501 to lift battery 501.

[0079] In the above embodiment, a battery storage unit provided in a printer and a battery stored therein have been used as an example, but such a battery storage unit and a battery stored therein may also be applied to other electronic devices.

[0080] The present invention can be embodied in various other forms without departing from its spirit or main characteristics. Therefore, the above-described embodiments are merely examples and should not be interpreted as limiting. The scope of the present invention is defined by the claims and is not limited to the text of the specification. Furthermore, all modifications and variations within the equivalent range of the claims are within the scope of the present invention. [Explanation of symbols]
