Printing device, protective cover and printing device main body

Abstract

To provide a printing device that is configured so that a protective cover attached to the printing device can be suppressed from positionally shifting, a protective cover, and a printing device main body.SOLUTION: In a printing device, a protective cover is attached to a printing device main body 2. An enclosure 10 of the printing device main body 2 has a protected region P which is covered with the protective cover to be protected and an exposed region E which is exposed without being covered with the cover. The exposed region E is positioned closer to outside of the enclosure 20 than the protected region P. Therefore, when the protective cover is attached to the printing device, a regulation surface R which extends from the protected region P to the outside of the enclosure 20 to connect to the exposed region E suppresses the protective cover from moving due to impact or the like. This can suppress the protective cover from interfering with opening and closing of an opening / closing cover 10, due to the positional shift of the protective cover.SELECTED DRAWING: Figure 7

[0003] [Patent Document 1] Patent Application No. 2007-160771 Summary of the Invention [Problem to be solved by the invention]

[0004] If the protective cover is subjected to an impact when the recording device is being carried, the protective cover may become misaligned. If the opening interferes with the opening / closing part of the recording device, the opening / closing part of the recording device may become unable to be opened or closed.

[0005] An object of the present invention is to provide a printing device, a protective cover, and a printing device main body that can prevent misalignment of a protective cover attached to the printing device. [Means for solving the problem]

[0006] According to a first aspect of the present invention, there is provided a printing device having a printing device main body having a housing that houses a printing unit that prints on a printing medium, and a protective cover that covers and protects the housing, wherein the housing has a first outer surface having a first area and a second area aligned in a first direction, an opening in the first area of ​​the first outer surface that opens in a second direction that intersects with the first outer surface, and an opening / closing lid that opens and closes the opening, the protective cover covers at least a portion of the second area of ​​the first outer surface, and the housing has a first regulating surface in the second area of ​​the first outer surface that extends from the first outer surface in the second direction and contacts the protective cover in the first direction to regulate movement of the protective cover toward the first area.

[0007] The protective cover of the first aspect comes into contact with the first restriction surface of the housing, restricting movement of the protective cover to the first region. This prevents the protective cover from shifting out of position due to impact or the like, and prevents the protective cover from interfering with the opening and closing of the access cover.

[0008] In a first aspect, the housing has a second outer surface that is connected to an end of the first outer surface in the first direction and extends in the second direction, and a third outer surface that is connected to an end of the first outer surface in a third direction that intersects the first direction and the second direction and extends in the second direction, the second outer surface has a third region and a fourth region that are aligned in the third direction, and the third outer surface has a fifth region and a sixth region that are aligned in the first direction, and the housing has a corner where the second outer surface and the third outer surface connect to the third region of the second outer surface and the fifth region of the third outer surface. The protective cover may have a first corner portion that is a first corner portion, the protective cover extending continuously from the second region to cover the third region and the fifth region, and the housing may have, in the third region of the second outer surface, a second restriction surface that extends from the second outer surface in the first direction and contacts the protective cover in the third direction to restrict movement of the protective cover to the fourth region, and a third restriction surface that extends from the third outer surface in the third direction and contacts the protective cover in the first direction to restrict movement of the protective cover to the sixth region. The protective cover also contacts the second restriction surface and the third restriction surface of the housing, so movement of the protective cover to the fourth region and the sixth region is restricted.

[0009] In the first aspect, the housing has a fourth outer surface that is connected to an end of the first outer surface opposite to the third outer surface in the third direction and extends in the second direction, the third outer surface has a seventh region and an eighth region that are aligned in the second direction, the fourth outer surface has a ninth region and a tenth region that are aligned in the second direction, and the housing has a second corner portion that is a corner portion where the first outer surface and the third outer surface are connected in the second region of the first outer surface and the seventh region of the third outer surface, and a second corner portion that is a corner portion where the first outer surface and the fourth outer surface are connected in the second region of the first outer surface and the ninth region of the fourth outer surface. The protective cover may have a third corner portion where the seventh and ninth regions are connected, the protective cover extending continuously from the second region to cover the seventh and ninth regions, and the housing may have a fourth restriction surface in the seventh region of the third outer surface, extending from the third outer surface in the third direction and contacting the protective cover in the second direction to restrict movement of the protective cover toward the eighth region, and a fifth restriction surface in the ninth region of the fourth outer surface, extending from the fourth outer surface in the third direction and contacting the protective cover in the first direction to restrict movement of the protective cover toward the tenth region. Because the protective cover contacts both the fourth and fifth restriction surfaces of the housing, movement of the protective cover toward the eighth and tenth regions is restricted. This allows the printing device to more reliably suppress misalignment due to impact or the like.

[0010] In a first aspect, the first outer surface of the housing may have an eleventh region aligned with the second region on one side in the third direction and a twelfth region aligned with the second region on the other side in the third direction, and the housing may have, in the second region of the first outer surface, a sixth restriction surface extending from the first outer surface in the second direction and contacting the protective cover on one side in the third direction to restrict movement of the protective cover toward the eleventh region, and a seventh restriction surface extending from the first outer surface in the second direction and contacting the protective cover on the other side in the third direction to restrict movement of the protective cover toward the twelfth region. Because the protective cover contacts both the sixth restriction surface and the seventh restriction surface of the housing, movement of the protective cover toward the eleventh and twelfth regions is restricted. This allows the printing device to more reliably suppress misalignment due to impact or the like.

[0011] In a first aspect, the housing may include a display unit for displaying a screen on a specific outer surface, which is one of the outer surfaces. The specific outer surface may have a formation area in which the display unit is formed and a peripheral area surrounding the formation area. The housing may also include a specific restriction surface in the peripheral area of ​​the specific outer surface, extending from the peripheral area toward the outside of the housing and contacting the protective cover to restrict movement of the protective cover toward the formation area. The protective cover is disposed surrounding the periphery of the display unit while contacting the specific restriction surface, thereby restricting movement toward the formation area. Therefore, the printing device can protect the display unit while suppressing displacement of the protective cover due to impact or the like.

[0012] In a first aspect, the housing may include a battery mounting port on a specific outer surface, which is one of the outer surfaces, and the specific outer surface may include a formation region where the battery mounting port is formed and a peripheral region surrounding the formation region. The housing may include a specific restriction surface in the peripheral region of the specific outer surface, extending from the peripheral region toward the outside of the housing and contacting the protective cover to restrict movement of the protective cover toward the formation region. The protective cover is disposed surrounding the periphery of the battery mounting port while contacting the specific restriction surface, thereby restricting movement toward the formation region. Therefore, the printing device can protect the battery mounting port while suppressing displacement of the protective cover due to impact or the like.

[0013] In a first aspect, the housing may include a specific outer surface, one of the outer surfaces, that includes a connector mounting portion to which an external power supply and a communication connector can be attached. The specific outer surface may include a formation region in which the connector mounting portion is formed and a peripheral region surrounding the formation region. The housing may also include a specific restriction surface in the peripheral region of the specific outer surface that extends from the peripheral region toward the outside of the housing and contacts the protective cover to restrict movement of the protective cover toward the formation region. The protective cover is positioned to surround the periphery of the connector mounting portion while contacting the specific restriction surface, thereby restricting movement toward the formation region. Therefore, the printing device can protect the connector mounting portion while suppressing displacement of the protective cover due to impact or the like.

[0014] In a first aspect, the housing may include a lever for opening and closing the opening / closing cover on a specific outer surface, which is one of the outer surfaces. The specific outer surface may have a formation region where the lever is formed and a peripheral region surrounding the formation region. The housing may also include a specific restriction surface in the peripheral region of the specific outer surface that extends from the peripheral region toward the outside of the housing and contacts the protective cover to restrict movement of the protective cover toward the formation region. The protective cover is disposed surrounding the periphery of the lever while contacting the specific restriction surface, thereby restricting movement toward the formation region. Therefore, the printing device can protect the lever while suppressing displacement of the protective cover due to impact, etc.

[0015] In a first aspect, the housing may include a strap hole on a specific outer surface, which is one of the outer surfaces, for attaching a strap to the housing. The specific outer surface may include a formation area in which the strap hole is formed and a peripheral area surrounding the formation area. The housing may include a specific restriction surface in the peripheral area of ​​the specific outer surface, extending from the peripheral area toward the outside of the housing and contacting the protective cover to restrict movement of the protective cover toward the formation area. The protective cover is positioned surrounding the periphery of the strap hole while contacting the specific restriction surface, thereby restricting movement toward the formation area. Therefore, the printing device can protect the strap hole while suppressing displacement of the protective cover due to impact or the like.

[0016] In a first aspect, the housing may include a clip attachment portion on a specific outer surface, which is one of the outer surfaces, that allows a clip to be attached to the housing. The specific outer surface may include a formation region where the clip attachment portion is formed and a peripheral region that surrounds the formation region. The housing may also include a specific restriction surface in the peripheral region of the specific outer surface that extends from the peripheral region toward the outside of the housing and contacts the protective cover to restrict movement of the protective cover toward the formation region. The protective cover is positioned surrounding the clip attachment portion while contacting the specific restriction surface, thereby restricting movement toward the formation region. Therefore, the printing device can protect the clip attachment portion while suppressing displacement of the protective cover due to impact or the like.

[0017] In a first aspect, all outer surfaces of the housing may each have a protected area where the outer surface is covered by the protective cover and an exposed area where the outer surface is not covered by the protective cover, and the housing may have a restricting surface in the protected area on all outer surfaces that extends from the protected area toward the outside of the housing and contacts the protective cover to restrict movement of the protective cover toward the exposed area. The protective cover is restricted from moving toward the exposed area by contacting the restricting surface of the housing. The housing has a restricting surface on all outer surfaces. Therefore, the printing device can suppress displacement of the protective cover due to impact or the like on all outer surfaces of the housing.

[0018] In the first aspect, an end face of the opening / closing cover on the first outer surface of the housing when the opening is closed may function as the first restriction surface. The protective cover is restricted from moving to the first region by contacting the end face of the opening / closing cover. Therefore, even if the protective cover is displaced due to an impact or the like, it will not ride up on the opening / closing cover and will not interfere with opening and closing the opening / closing cover.

[0019] In a first aspect, the protective cover may have a first chamfered surface formed by chamfering a corner between a contact surface that contacts the first restriction surface and an outward surface that faces outward from the housing. By having the first chamfered surface, the protective cover can prevent a user's finger or the like from getting caught on the contact surface of the protective cover, which can cause the protective cover to become misaligned.

[0020] In the first aspect, the housing may have a second chamfered surface formed by chamfering a corner between the first restriction surface and the first outer surface. Since the second chamfered surface is formed on the housing to match the first chamfered surface of the protective cover, the printing device does not spoil its aesthetic appearance.

[0021] In the first aspect, the length by which the contact surface extends outward from the housing may be equal to or shorter than the length by which the first restriction surface and the second chamfered surface extend outward from the housing. Since the user's fingers or the like are less likely to get caught on the contact surface of the protective cover, the protective cover can be prevented from shifting.

[0022] In the first aspect, the protective cover may be made of an elastomer material. Because the protective cover is made of an elastic material, it is difficult for the protective cover to shift out of position when pulled and fitted into the housing.

[0023] In the first aspect, the protective cover may be formed from a single part in which all of the portions of the outer surface of the housing that are to be placed in the protective area are integrally formed. By molding the protective cover from a single part, the manufacturing costs of the printing device can be reduced.

[0024] In the first aspect, the length by which the outward surface of the protective cover extends outward from the housing may be longer than the length by which the first outer surface of the housing extends outward from the housing. Because the outward surface of the protective cover is located more outer than the first outer surface of the housing, the protective cover can protect the first outer surface.

[0025] In the first aspect, a medium loading section for loading the print medium may be disposed within the opening of the housing. The protective cover does not interfere with the opening and closing of the opening / closing lid, so that the print medium can be loaded smoothly without needing to be removed.

[0026] According to a second aspect of the present invention, there is provided a protective cover for covering and protecting a housing of a printing device main body having a housing that houses a printing unit that prints on a print medium, the housing of the printing device main body having a first outer surface having a first region and a second region aligned in a first direction, an opening in the first region of the first outer surface that opens in a second direction that intersects with the first outer surface, an opening / closing cover for opening and closing the opening, and a first restriction surface in the second region of the first outer surface that extends from the first outer surface in the second direction and comes into contact with the protective cover in the first direction when attached to the housing to restrict movement of the protective cover toward the first region, wherein the protective cover covers at least a portion of the second region of the first outer surface when attached to the housing. Thus, the second aspect provides the same effects as the first aspect.

[0027] According to a third aspect of the present invention, there is provided a printing device main body having a housing that houses a printing unit that prints on a print medium, the housing having a first outer surface having a first region and a second region aligned in a first direction, an opening in the first region of the first outer surface that opens in a second direction that intersects with the first outer surface, an opening / closing cover that opens the opening, and a first restriction surface in the second region of the first outer surface that extends from the first outer surface in the second direction and contacts the protective cover in the first direction to restrict movement of the protective cover toward the first region when a protective cover is attached to the housing, so that when the protective cover is attached to the housing, at least a portion of the second region of the first outer surface is covered. Therefore, the third aspect provides the same effects as the first aspect. [Brief explanation of the drawings]

[0029] A printing device 1 according to a first embodiment of the present invention will be described with reference to the drawings. The drawings are used to explain the technical features that can be adopted by the present invention, and the configuration of the device described is not intended to be limiting, but is merely an illustrative example.

[0030] The printing device 1 shown in FIGS. 1 and 2 can print characters, graphics, and the like on a printing medium based on printing data received from an external terminal. The printing medium is, for example, a thermal label, which is used as a roll of label tape T attached to a mount and wound up. The printing device 1 is usually used by placing it on a desk with its bottom surface 26 (the surface facing downward in FIG. 1) facing downward, but it can also be used by hanging it from a user's waist belt, for example, by attaching a belt clip 19 (see FIG. 2). In this state, the printing device 1 is in a vertical position with its bottom surface 26 raised, and the side on which the display unit 12 is located faces upward. For convenience of explanation, this embodiment will be described in terms of the front-to-back, left-to-right, and up-to-down orientations shown in the figures, with the orientation when the printing device is used by placing it on a desk as the basic orientation.

[0031] The configuration of the printer 1 will be described with reference to FIGS. 1 to 6. As shown in FIGS. 1 and 2, the printer 1 includes a printer main body 2 and a protective cover 3. The housing 20 of the printer main body 2 is box-shaped and elongated in the front-to-rear direction. The housing 20 has an opening 27 that opens vertically, located rearward of the approximate center of the top surface 25 in the front-to-rear direction. The opening 27 is covered by the access cover 10. The printer main body 2 has a generally rectangular shape that is longer left-to-right than up-to-down, when viewed from the front (see FIG. 3(A)), and each of its four corners is rounded. The printer main body 2 has a generally rectangular shape that is longer front-to-rear than left-to-right, when viewed from the top (see FIG. 5), and each of its four corners is rounded. The printer main body 2 is longer front-to-rear than up-to-down, when viewed from the side (see FIG. 4) with the access cover 10 attached. The front end portion has a generally rectangular shape with rounded corners, and the rear end portion curves rearward in a generally semicircular shape. The protective cover 3 (described below) covers and protects the outer surface of the housing 20.

[0032] As shown in FIGS. 1 and 3A, the front surface 21 of the housing 20 of the printer main body 2 is provided with a display unit 12, a strap hole 13, and a clip attachment unit 14. The display unit 12 is a rectangular LCD screen that is long in the left-right direction and is located approximately in the center of the front surface 21. The display unit 12 displays various information such as the operating status, settings, and messages of the printer 1. The strap hole 13 is formed at the lower right of the display unit 12 and consists of two holes lined up on the left and right sides that are connected inside the housing 20. A strap (not shown) can be attached to the strap hole 13. The user can carry the printer 1 by hanging it from a strap attached to the strap hole 13. The clip attachment unit 14 is rod-shaped and extends left-right, and is located below the display unit 12 at the corner where it meets the bottom surface 26. The clip attachment part 14 has a recess 141 formed around the body part, and the hook-shaped attachment part 191 (see FIG. 2) of the belt clip 19 can be passed through the recess 141 and hooked onto the clip attachment part 14. A hook-shaped clip 192 is connected to the attachment part 191, and the belt clip 19 can be attached to a user's waist belt or the like, allowing the printing device 1 to be hung from the user's waist belt.

[0033] The housing 20 houses a printing unit 11 (see FIG. 1), a circuit board (not shown), a feed motor (not shown), etc. The printing unit 11 has a line thermal head capable of printing on thermal labels. The printing unit 11 is provided at the top of the housing 20 and approximately in the center in the front-to-back direction. The printing unit 11 is exposed inside a tape mounting section 18 (described below) and faces a platen roller (not shown) provided on the opening / closing cover 10 from the front side when the opening / closing cover 10 is closed. The circuit board is housed in the front part of the housing 20 and approximately in the center in the up-to-down direction. A CPU (not shown) and other components are mounted on the circuit board and control the operation of the printer 1. The feed motor is provided at the bottom of the housing 20, approximately in the center in the front-to-back direction, and feeds the label tape. The feed motor transmits driving force to the platen roller via a gear (not shown) when the opening / closing cover 10 is closed.

[0034] The opening 27 of the housing 20 opens at the rear of the top surface 25 of the housing 20, at the upper rear portions of the left and right surfaces 23 and 24 in the front-to-rear direction, and at the upper portion of the rear surface 22. A tape mounting section 18 is disposed within the opening 27. A roll of label tape T is housed in the tape mounting section 18. The tape mounting section 18 has an open top within the opening 27, and the label tape T is mounted vertically. The opening / closing lid 10 covers the opening 27 and closes the top, tops on both the left and right sides, and top on the rear side of the tape mounting section 18, protecting the label tape T housed in the tape mounting section 18. The housing 20 has a holder 181 within the tape mounting section 18. The holder 181 clamps the roll of label tape T from both the left and right sides.

[0035] As shown in FIGS. 1 to 5, the opening / closing cover 10 is a generally rectangular plate in plan view, with both left and right edge portions and the rear edge portion curving downward in an arc. When the opening / closing cover 10 is closed, the rear edge portion extends to approximately the vertical center of the housing 20. The left and right edge portions extend approximately one-quarter of the vertical length in the front-to-rear direction, and the rear portion curves downward in an arc and extends to approximately the vertical center of the housing 20. The rear end portion of the opening / closing cover 10 is provided at the upper end of the wall portion behind the tape attachment portion 18 of the housing 20 and is pivotally supported by a shaft (not shown) extending in the left-to-right direction. Therefore, the opening / closing cover 10 opens and closes the opening 27 of the housing 20 by swinging its front end vertically relative to its rear end. When the opening / closing cover 10 is opened, the tape attachment portion 18 is released. A helical spring, for example, is attached to the shaft portion. Therefore, the opening / closing cover 10 is biased from a state in which it closes the tape mounting portion 18 to a state in which it opens the tape mounting portion 18.

[0036] As shown in FIGS. 1 and 4A, a battery mounting port 15, a connector mounting portion 16, and a lever 17 are provided on the right side 24 of the housing 20 of the printer main body 2. The battery mounting port 15 is a mounting port for mounting a battery that supplies power to operate the printer main body 2 into a battery mounting portion (not shown) inside the housing 20. The battery mounting port 15 is rectangular and is located on the lower left side of the center of the right side 24. The connector mounting portion 16 is used to mount, for example, a connector (not shown) of an AC adapter that supplies power to operate the printer main body 2. The printer main body 2 is powered by power supplied from the AC adapter or a battery. The battery is charged by power supplied from the AC adapter. The connector mounting portion 16 is provided above the battery mounting port 15. The lever 17 is an operating portion for disengaging a hook (not shown) provided on the access cover 10 from an engagement portion (not shown) provided on the housing 20 that engages with the hook to keep the access cover 10 closed. When not in operation, lever 17 is biased upward, and when the user presses lever 17 downward, the engagement state is released and opening / closing cover 10 is opened by the coil spring. Lever 17 is located behind battery mounting port 15 and connector mounting portion 16.

[0037] Next, the configurations of the printer body 2 and the protective cover 3 will be described. The protective cover 3, which protects the exterior of the printer body 2, is detachable from the printer body 2. The protective cover 3 is made of an elastic elastomer and is attached by placing it over the printer body 2. The protective cover 3 is formed as a single, integrated cover so as not to cover the areas where the access cover 10, display 12, strap hole 13, clip attachment portion 14, battery port 15, connector attachment portion 16, and lever 17 of the printer body 2 are located, but rather to cover and protect at least a portion of each area of ​​the entire exterior of the housing 20. Therefore, the protective cover 3 can be attached to and detached from the printer body 2 by expanding the area to be opened so that the protective cover 3 does not cover the access cover 10. The printer 1 has distinctive shapes for the exterior of the housing 20 and the protective cover 3, so that the protective cover 3, configured as described above, is less likely to shift relative to the portion protecting the exterior of the printer body 2 due to, for example, an impact received during use of the printer 1.

[0038] 7 to 11, the shape of the outer surface of the housing 20 of the printer body 2 will be described. The housing 20 of the printer body 2 has, on all of its outer surfaces, the front surface 21, rear surface 22, left surface 23, right surface 24, top surface 25, and bottom surface 26, a protected area P where the outer surface is covered by the protective cover 3, and an exposed area E where the outer surface is not covered by the protective cover 3 and is exposed.

[0039] As shown in Figures 7(A), 9(A), and 10, the front end of the opening / closing cover 10 with the opening 27 closed is located on the top surface 25 of the housing 20 at a position slightly forward of approximately the center in the front-to-rear direction. Using the position of the front end as a reference, the area on the rear side of the top surface 25 in the front-to-rear direction is defined as the first area, and the area on the front side is defined as the second area. The opening 27 and the opening / closing cover 10 are located in the first area of ​​the top surface 25. The protective cover 3 is not located in the first area so as not to interfere with the opening and closing of the opening / closing cover 10. Therefore, the first area of ​​the top surface 25 is configured as an exposed area E251. Note that the exposed area E251 is one of the exposed areas E on the top surface 25.

[0040] Meanwhile, protective cover 3 covers at least a portion of the second area of ​​top surface 25. That is, at least a portion of the second area of ​​top surface 25 is configured as protected area P251. Note that protected area P251 is one of the protected areas P on top surface 25. In addition, in the second area, exposed area E252 that is not covered by protective cover 3 is also arranged in front of protected area P251.

[0041] Furthermore, the exposed areas E251 and E252 are located outside the housing 20 compared to the protected area P251 (see FIG. 9(A)). That is, the exposed areas E251 and E252 on the top surface 25 are located above the protected area P251. Therefore, on the top surface 25, the protected area P251 is sandwiched in the front-to-rear direction between the exposed area E251 of the first area and the exposed area E252 of the second area, and extends in the left-to-right direction like a groove. The side of the groove that extends upward from the protected area P251 and connects to the exposed area E251 is the restricting surface R251. The restricting surface R251 is the portion of the surface facing forward at the front end of the opening / closing cover 10 that extends above the protected area P251 when the opening / closing cover 10 is closed. As will be described later, the protective cover 3 located in the protected area P251 is restricted from moving rearward by abutting against the restricting surface R251. The side of the groove that extends upward from the protected area P251 and connects to the exposed area E252 is a restricting surface R252. The restricting surface R252 faces rearward. When the protective cover 3 placed in the protected area P251 abuts against the restricting surface R252, its forward movement is restricted.

[0042] The exposed area E252 has two left-right ends that do not reach the left-right ends of the top surface 25. Protective areas P252 and P253 extending in the front-rear direction are formed on the left and right sides of the exposed area E252. The protective area P252 connects to the right end of the protective area P251 and extends to the front end of the top surface 25 on the right side of the exposed area E252.

The side of the groove that extends upward from the protective area P252 and connects to the exposed area E252 is the restricting surface R253. The restricting surface R253 faces right. The protective cover 3 placed in the protective area P252 is restricted from moving leftward by abutting against the restricting surface R253. The side of the groove that extends upward from the protected region P253 and connects to the exposed region E252 is a restricting surface R254. The restricting surface R254 faces left. When the protective cover 3 placed in the protected region P253 abuts against the restricting surface R254, it is restricted from moving to the right.

[0043] As shown in FIGS. 7A and 8A, the front surface 21 of the housing 20 is connected to the front end of the top surface 25 and extends in the vertical direction. The exposed area E252 in the second region of the top surface 25 is connected to the exposed area E21 extending in the vertical direction on the front surface 21. The display unit 12, strap hole 13, and clip attachment portion 14 on the front surface 21 are arranged in the exposed area E21. The protective areas P252 and P253 in the second region of the top surface 25 are connected to protective areas P211 and P212 on the front surface 21, respectively, which extend in the vertical direction on both sides of the exposed area E21. The exposed area E21 is located outside the housing 20 compared to the protective areas P211 and P212 (see FIG. 10). In other words, the exposed area E21 on the front surface 21 is located forward of the protective areas P211 and P212. The side of the groove that extends forward from the protected region P211 and connects to the exposed region E21 is the restricting surface R211. The restricting surface R211 faces to the right. The protective cover 3 placed in the protected region P211 is restricted from moving to the left by abutting against the restricting surface R211.

On the left surface 23, protected areas P231, P232, P233, and P234 are formed around the exposed area E231. The protected areas P231 to P234 are respectively arranged in front of, above, behind, and below the exposed area E231.

The portion of the cover 10 that extends downward on the left side is located on the left surface 23 and is disposed above the protected area P232 as an exposed area E232.

[0047] The exposed areas E231, E232 are located outside the housing 20 compared to the protected areas P231 to P234. That is, the exposed areas E231, E232 on the left surface 23 are located to the left of the protected areas P231 to P234.

The protective cover 3 arranged in the protected region P234 is restricted from upward movement by abutting against the restricting surface R234.

[0048] As shown in FIGS. 7(B) and 8(B), the rear end of the opening / closing cover 10 with the opening 27 closed is located approximately in the center of the rear surface 22 of the housing 20 in the vertical direction. An exposed area E221 extending in the left-right direction is formed at the bottom of the rear surface 22. Protected areas P221, P222, P223, and P224 are formed around the exposed area E221 on the rear surface 22. The protected areas P221 to P224 are located to the right, above, left, and below the exposed area E221, respectively. The protected areas P221 to P224 are connected to one another and are located around the exposed area E221. The protected area P221 connects with a protected area P243 on the right surface 24 at the rear right corner of the housing 20. The protected area P223 connects with a protected area P233 on the left surface 23 at the rear left corner of the housing 20. Furthermore, the portion of the cover 10 that extends downward on the rear side is located on the rear surface 22 and is disposed above the protected area P222 as an exposed area E222.

[0049] The exposed areas E221, E222 are located outside the housing 20 compared to the protected areas P221 to P224. That is, the exposed areas E221, E222 on the rear surface 22 are located rearward of the protected areas P221 to P224. The side of the groove that extends rearward from the protected area P221 and connects to the exposed area E221 is the restricting surface R221. The restricting surface R221 faces rightward.

[0050] As shown in FIGS. 7(B) and 11, the exposed area E26 formed at the front end of the bottom surface 26 of the housing 20 is connected to the exposed area E21 extending in the up-down direction on the front surface 21. Protective areas P261, P262 are formed on both the left and right sides of the exposed area E26, respectively, and extend in the front-rear direction and connect to the protective areas P212, P212 on the front surface 21. The exposed area E26 is provided on the front side in the front-rear direction, and the portion behind the exposed area E26 is formed as the protective area P263. The protective area P263 is connected to the protective areas P261, P262. The exposed area E26 is located outside the housing 20 compared to the protective areas P261 to P263. In other words, the exposed area E26 on the bottom surface 26 is located below the protective areas P261 to P263. The side surface of the groove extending downward from the protective area P261 to connect to the exposed area E26 is the restricting surface R261. The restricting surface R261 faces to the right. The protective cover 3 placed in the protected area P261 is restricted from moving to the left by abutting against the restricting surface R261. In addition, the side of the groove that extends downward from the protected area P262 and connects to the exposed area E26 is the restricting surface R262. The restricting surface R262 faces to the left. The protective cover 3 placed in the protected area P262 is restricted from moving to the right by abutting against the restricting surface R262.

[0051] The shape of the protective cover 3 will be described with reference to FIGS. 12 to 16. As described above, the protective cover 3 is made of elastomer and is formed as a single, integrated part. Protective portions 361, 362, and 363 are formed at the bottom of the protective cover 3, covering the protective areas P261, P262, and P263 of the bottom surface 26 of the housing 20, respectively. Protective portion 361 extends forward from the right front corner of protective portion 363, and protective portion 362 extends forward from the left front corner of protective portion 363. The left end of protective portion 361, the right end of protective portion 362, and the front end of protective portion 363 form a trapezoidal cutout 366 that cuts out the bottom from the front side. The exposed area E26 of the bottom surface 26 of the housing 20 is disposed within cutout 366.

[0052] Protective portions 311 and 312 are formed at the front of the protective cover 3, respectively covering protective areas P211 and P212 of the front surface 21 of the housing 20. Protective portions 311 and 312 extend upward from the front ends of protective portions 361 and 362, respectively. The area between protective portions 311 and 312 is connected to a notch 366, where exposed area E21 of the front surface 21 of the housing 20 is located.

[0053] Protective portions 341, 342, 343, and 344 are formed on the right side of protective cover 3, respectively covering protective areas P241, P242, P243, and P244 on the right surface 24 of the housing 20. Protective portion 341 is connected to protective portion 361 and protective portion 311 and extends in the vertical direction. Protective portion 341 and protective portion 311 cover the right front corner of the housing 20. Protective portion 342 extends rearward from the upper end of protective portion 341. Protective portion 344 extends rearward from the lower end of protective portion 341. The lower end of protective portion 344 connects to the right end of bottom protective portion 361 and the right end of protective portion 363, covering the lower right corner of the housing 20. Protective portion 343 connects the rear end of protective portion 342 and the rear end of protective portion 344 in the vertical direction. Protective portions 341 to 344 are arranged to surround the periphery of opening 346, which extends in the front-to-rear direction. An exposed area E241 on the right surface 24 of housing 20 is arranged within opening 346. A notch 347 cut out from the top is formed at the rear of protective portion 342. An exposed area E242 provided on the portion extending downward on the right side of opening / closing cover 10 is arranged in notch 347.

[0054] Protective portions 331, 332, 333, and 334 are formed on the left side of protective cover 3, respectively covering protective areas P231, P232, P233, and P234 on left surface 23 of housing 20. Protective portion 331 is connected to protective portion 362 and protective portion 312 and extends in the vertical direction. Protective portion 331 and protective portion 312 cover the left front corner of housing 20. Protective portion 332 extends rearward from the upper end of protective portion 331. Protective portion 334 extends rearward from the lower end of protective portion 331. The lower end of protective portion 334 connects to the left end of bottom protective portion 362 and the left end of protective portion 363, covering the lower left corner of housing 20. Protective portion 333 connects the rear end of protective portion 332 and the rear end of protective portion 334 in the vertical direction. Protective portions 331 to 334 are arranged to surround the periphery of opening 336, which extends in the front-to-rear direction. An exposed area E231 on the left surface 23 of housing 20 is arranged within opening 336. A notch 337 cut out from the top is formed at the rear of protective portion 332. An exposed area E232 provided on the portion extending downward on the left side of opening / closing cover 10 is arranged in notch 337.

[0055] The rear of the protective cover 3 is formed with protective portions 321, 322, 323, and 324 that respectively cover protective areas P221, P222, P223, and P224 on the rear surface 22 of the housing 20. Protective portion 321 is connected to protective portion 363 and protective portion 343 and extends in the vertical direction. Protective portion 321 and protective portion 343 cover the right rear corner of the housing 20. Protective portion 322 extends rightward from the upper end of protective portion 321. Protective portion 324 extends rightward from the lower end of protective portion 321. The lower end of protective portion 324 connects to the rear end of protective portion 363 at the bottom and covers the lower rear corner of the housing 20. Protective portion 323 connects the right end of protective portion 322 to the right end of protective portion 324 in the vertical direction. Protective portion 323 is connected to protective portion 363 and protective portion 333 and extends vertically. Protective portion 323 and protective portion 333 cover the left rear corner of housing 20. Protective portions 321 to 324 are arranged to surround the periphery of opening 326, which extends in the left-right direction. An exposed area E221 of rear surface 22 of housing 20 is disposed within opening 326. An upper end 327 of protective portion 322 is disposed approximately in the center in the up-down direction. An exposed area E222 provided on the portion extending downward on the rear side of opening / closing cover 10 is disposed at upper end 327.

[0056] Protective portions 351, 352, and 353 are formed on the top of protective cover 3, covering protective areas P251, P252, and P253 on top surface 25 of housing 20, respectively. Protective portion 351 extends forward from the right front corner of protective portion 353, and protective portion 352 extends forward from the left front corner of protective portion 353. A trapezoidal cutout portion 356 is formed in the top from the front side by the left end of protective portion 351, the right end of protective portion 352, and the front end of protective portion 353. An exposed area E252 on top surface 25 of housing 20 is disposed within cutout portion 356. Cutout portion 356 is connected to the area between protective portions 311 and 312 on the front side. Therefore, the top protective portions 351, 352, 353, the front protective portions 311, 312, and the bottom protective portions 361, 362, 363 are arranged to surround the exposed areas E252, E21, E26 that are continuously connected from the top surface 25 of the housing 20 through the front surface 21 to the bottom surface 26.

[0057] In this way, the protective portion of the protective cover 3 is not disposed in the exposed region located outside the protected region of the housing 20, but is disposed in the protected region, and movement is restricted by a restricting surface that rises from the protected region toward the exposed region, thereby suppressing misalignment with respect to the outer surface of the housing 20. Also, as shown in Fig. 17 , in the direction from inside the housing 20 to the outside of the housing 20, the outward surface 38 of the protective cover 3 facing the outside of the housing 20 is located outside the outer surface of the housing 20 (top surface 25 in Fig. 17 ). In other words, when the length (distance) from inside the housing 20 to the outward surface 38 is H1 and the length (distance) from inside the housing 20 to the top surface 25 in the exposed region E252 is H2, the protective cover 3 satisfies H1>H2. The position within the housing 20 that serves as the reference for distance may be, for example, the center position within the housing 20, or the distance may be measured in a direction perpendicular to the outer surface of the housing 20 near the position to be compared, and any position inside the housing 20 in that direction may be used as the reference position. Therefore, for example, if the printing device 1 collides with an obstacle outside the housing 20, the outward surface 38 of the protective cover 3 can come into contact with the obstacle before the outer surface of the housing 20 in the exposed area, thereby preventing damage to the outer surface of the exposed area.

[0058] Furthermore, the protective cover 3 has an end face of the protective portion 351 arranged in the protection area P251 that comes into contact with the restricting surface R252 of the housing 20. The end face that comes into contact with the restricting surface R252 is called the contact surface 37. The protective cover 3 has a chamfered surface 39 that is C-chamfered at the corner between the contact surface 37 and the outward surface 38. Even if a user touches the protective cover 3 while handling the printing device 1, the chamfered surface 39 is unlikely to catch on the user's fingers, etc., and the protective portion 351 is unlikely to be peeled off from the protection area P251. This prevents the protective cover 3 from shifting position or becoming unintentionally detached from the housing 20.

[0059] Furthermore, the housing 20 has a chamfered surface 29 formed by C-chamfering at the corner between the restricting surface 252 and the top surface 25 in the exposed region E252. By providing chamfered surfaces 39, 29 on both the outward surface 38 of the protective cover 3 and the top surface 25 of the housing 20 at the contact position where the restricting surface 252 and the contact surface 37 come into contact, the difference in height (step) between the top surface 25 and the outward surface 38 can be made less noticeable, improving the appearance. Note that the corner between the contact surface 37 and the chamfered surface 39 of the protective cover 3 may be exposed at the contact position. To prevent the protective portion 351 from rolling up in this case, the outward surface 38 of the protective cover 3, which faces outward from the housing 20, is located outside or at the same position as the contact surface 37 in the direction from inside the housing 20 to outside the housing 20. That is, when the length (distance) from inside the housing 20 to the top surface 25 in the exposed area E252 is H2 and the length (distance) to the connection position (boundary position) between the contact surface 37 and the chamfered surface 39 is H3, the protective cover 3 satisfies H2 ≧ H3. Since it becomes difficult for the user's fingers or the like to touch the connection position between the contact surface 37 and the chamfered surface 39, the protective cover 3 is prevented from shifting position or being unintentionally detached from the housing 20.

[0060] 18, at the front end of the opening / closing cover 10, the side facing the opening / closing cover 10 may be the exposed area E251, and the side facing the housing 20 may be the protected area P251. In this case, the surface at the front end of the opening / closing cover 10 that faces the protected area P251 is the restricting surface 251. The opening / closing cover 10 prevents the protective cover 3 from shifting in position by using the restricting surface 251, making it less likely that misalignment of the protective cover 3 will interfere with opening and closing.

[0061] Next, a printing device 6 of a second embodiment will be described. The printing device 6 of the second embodiment shown in Figures 19 to 24 has an external shape that is different from the printing device 1 of the first embodiment. Therefore, the following will only describe the shape of the printing device 6, and the same reference numerals will be used for parts with the same configuration, and descriptions thereof will be omitted or simplified.

[0062] As shown in Figures 19 and 20, the printer 6 includes a printer main body 7 and a protective cover 8. The housing 70 of the printer main body 7 has an opening 27 that opens vertically at the rear of the top surface 75. A tape mounting unit 18 is disposed within the opening 27. A roll of label tape T is housed in the tape mounting unit 18. The opening 27 is covered by an opening / closing cover 60. The printer main body 7 has a generally rectangular shape that is longer in the left-right direction than in the up-down direction when viewed from the front (see Figure 21(A)), with each of the four corners being significantly C-chamfered and then slightly R-chamfered. The printer main body 7 has a generally rectangular shape that is longer in the front-to-back direction than in the left-to-right direction when viewed from the front (see Figure 23), with each of the four corners being significantly C-chamfered and then slightly R-chamfered. The printer main body 7 is longer in the front-to-back direction than in the up-to-down direction when viewed from the side (see Figure 22) with the opening / closing cover 60 attached. The front end portion is roughly rectangular with rounded corners, and the rear end portion is curved rearward into a roughly semicircular shape. The protective cover 8 covers and protects the outer surface of the housing 70. The protective cover 8 is made of an elastic elastomer and is attached by placing it over the printing device main body 7.

[0063] As shown in FIGS. 19 and 21A, a display unit 12, a strap hole 13, and a clip attachment unit 14 are provided on the front surface 71 of the housing 70 of the printer main body 7. As shown in FIGS. 19 and 22A, a battery mounting port 15, a connector mounting unit 16, and a lever 17 for opening the access cover 60 are provided on the right surface 74 of the housing 70 of the printer main body 7. As shown in FIGS. 19 to 23, the access cover 60 has a generally rectangular plate shape in a plan view, with the rear edge curved in an arc and extending downward. When the access cover 60 is closed, the rear edge extends to approximately the center of the housing 70 in the up-down direction. The rear end of the access cover 60 is pivotally supported by the housing 70. The access cover 60 opens and closes the opening 27 of the housing 70 by swinging its front end up and down relative to its rear end.

[0064] 25 to 29, the shape of the outer surface of the housing 70 of the printing device main body 7 will be described. The housing 70 of the printing device main body 7 has a protected area P covered by the protective cover 8 on all of its outer surfaces, including the front surface 71, rear surface 72, left surface 73, right surface 74, top surface 75, and bottom surface 76, and an exposed area E that is not covered by the protective cover 8 and is exposed. In the printing device main body 7 of the second embodiment, the arrangement of the protected area P and the exposed area E on the outer surface is a shape that imitates a traditional, so-called hexagonal pattern, creating an aesthetically pleasing appearance. The protective cover 8 is arranged in the protected area P, but not in the exposed area E.

Protective portions 811 and 812 extend upward from the front ends of protective portions 861 and 862, respectively, and connect to the front ends of protective portions 851 and 852. The areas between protective portions 811 and 812 connect to notch 356 in the top portion and notch 366 in the bottom portion, respectively, to form a large opening. Exposed area E711 on front surface 71 of housing 70, exposed area E751 on top surface 75, and exposed area E761 on bottom surface 76 are disposed in this opening.

[0080] As shown in Figures 30(B) and 31(B), protective portions 821 and 822 are formed at the rear of protective cover 8, covering protective areas P721 and P722 on rear surface 72 of housing 70, respectively. Protective portions 821 and 822 extend upward from the rear ends of protective portions 863 and 864, respectively, and connect to the rear ends of protective portions 853 and 854. The areas between protective portions 821 and 822 connect to notches 357 and 367 in the top and bottom portions, respectively, to form a large opening. In this opening, openable / closable cover 60, which constitutes exposed area E752 from top surface 75 to rear surface 72 of housing 70, exposed area E721 on rear surface 72, and exposed area E762 on bottom surface 76 are disposed.

[0081] As shown in FIGS. 30(A) and 32(A), protective portions 841 and 842 are formed on the right side of protective cover 8, covering protective areas P741 and P742 on the right surface 74 of housing 70, respectively. Protective portions 841 and 842 extend upward from the right ends of protective portions 862 and 864, respectively, and connect to the right ends of protective portions 852 and 854. The front end of protective portion 841 connects to protective portion 812, and the rear end of protective portion 842 connects to protective portion 822. The areas between protective portions 841 and 842 connect to notches 359 and 369 in the top and bottom portions, respectively, to form a large opening. Exposed area E741 on the right surface 74 of housing 70, exposed area E754 on the top surface 75, and exposed area E764 on the bottom surface 76 are disposed in this opening.

[0082] As shown in FIGS. 30(B) and 32(B), protective portions 831 and 832 are formed on the left side of protective cover 8, covering protective areas P731 and P732 on the left surface 73 of housing 70, respectively. Protective portions 831 and 832 extend upward from the left ends of protective portions 861 and 863, respectively, and connect to the left ends of protective portions 851 and 853. The front end of protective portion 831 connects to protective portion 811, and the rear end of protective portion 832 connects to protective portion 821. The areas between protective portions 831 and 832 connect to notches 358 and 368 in the top and bottom portions, respectively, to form a large opening. Exposed area E731 on the left surface 73 of housing 70, exposed area E753 on the top surface 75, and exposed area E763 on the bottom surface 76 are disposed in this opening.

[0083] As described above, the protective covers 3, 8 come into contact with the restricting surfaces R251, R751 of the housings 20, 70, restricting movement of the protective covers 3, 8 into the first region. Therefore, the printing devices 1, 6 can suppress displacement of the protective covers 3, 8 due to impacts or the like, and can prevent the protective covers 3, 8 from interfering with the opening and closing of the opening and closing lids 10, 60.

[0084] The protective covers 3, 8 also come into contact with the restricting surfaces R211, R711 and R241, R741 of the housings 20, 70, so that movement of the protective covers 3, 8 to the exposed areas E21, E711 and E241, E741 is restricted.

[0085] The protective cover 3 also comes into contact with the restricting surfaces R242 and R232 of the housings 20 and 70, restricting movement of the protective cover 3 toward the exposed areas E241 and E231. This allows the printing device 1 to more reliably prevent displacement due to impact or the like.

[0086] The protective cover 8 also comes into contact with the restricting surfaces R75C and R75D of the housing 70, restricting movement of the protective cover 8 toward the exposed areas E753 and E754. This allows the printing devices 1 and 6 to more reliably prevent displacement due to impact or the like.

[0087] The protective covers 3, 8 are disposed so as to surround the periphery of the display unit 12 while contacting the restriction surfaces R211, R212, R252, R263, R71A, R71B, R75A, and R76A, thereby restricting movement toward the exposed areas E21, E711. Therefore, the printing devices 1, 6 can protect the display unit 12 while suppressing displacement of the protective covers 3, 8 due to impact or the like.

[0088] The protective covers 3, 8 are disposed so as to surround the battery mounting port 15 while in contact with the restriction surfaces R241, R242, R243, R244, R74A, R74B, R75D, and R76D, thereby restricting movement toward the exposed areas E241, E741. Therefore, the printing devices 1, 6 can protect the battery mounting port 15 while preventing the protective covers 3, 8 from shifting due to impact or the like.

[0089] The protective covers 3, 8 are disposed so as to surround the connector mounting portion 16 while contacting the restriction surfaces R241, R242, R243, R244, R74A, R74B, R75D, and R76D, thereby restricting movement toward the exposed areas E241 and E741. Therefore, the printing devices 1, 6 can protect the connector mounting portion 16 while suppressing displacement of the protective covers 3, 8 due to impacts or the like.

[0090] The protective covers 3, 8 are disposed so as to surround the lever 17 while in contact with the restriction surfaces R241, R242, R243, R244, R74A, R74B, R75D, and R76D, thereby restricting movement of the lever 17 toward the exposed areas E241, E741. Therefore, the printing devices 1, 6 can protect the lever 17 while suppressing displacement of the protective covers 3, 8 due to impacts or the like.

[0091] The protective covers 3, 8 are disposed so as to surround the strap hole 13 while in contact with the restriction surfaces R211, R212, R252, R263, R71A, R71B, R75A, and R76A, thereby restricting movement toward the exposed areas E21, E711. Therefore, the printing devices 1, 6 can protect the strap hole 13 while preventing the protective covers 3, 8 from shifting due to impact or the like.

[0092] The protective covers 3, 8 are disposed so as to surround the clip mounting portion 14 while in contact with the restriction surfaces R211, R212, R252, R263, R71A, R71B, R75A, and R76A, thereby restricting movement toward the exposed areas E21, E711. Therefore, the printing devices 1, 6 can protect the clip mounting portion 14 while suppressing displacement of the protective covers 3, 8 due to impacts or the like.

[0093] The protective cover 3, 8 comes into contact with the restricting surface R of the housing 20, 70, thereby restricting movement toward the exposed area E. The housing 20, 70 has restricting surfaces R on all outer surfaces. Therefore, the printing device 1, 6 can prevent the protective cover 3, 8 from shifting in position due to impact or the like on all outer surfaces of the housing 20, 70.

[0094] The protective covers 3, 8 are restricted from moving to the first region by contacting the end faces of the opening / closing lids 10, 60. Therefore, even if the protective covers 3, 8 are displaced due to an impact or the like, they will not ride up onto the opening / closing lids 10, 60 and will not interfere with the opening and closing of the opening / closing lids 10, 60.

[0095] The protective covers 3, 8 have the chamfered surfaces 39, which can prevent the user's fingers or the like from getting caught on the contact surfaces 37 of the protective covers 3, 8, causing the protective covers 3, 8 to become misaligned.

[0096] The printing devices 1, 6 have chamfered surfaces 29 formed on the housings 20, 70 to match the chamfered surfaces 39 of the protective covers 3, 8, so that the aesthetic appearance is not impaired.

[0097] By satisfying H2≧H3, the user's fingers or the like are less likely to get caught on the contact surfaces 37 of the protective covers 3 and 8, and therefore the protective covers 3 and 8 can be prevented from shifting out of position.

[0098] Since elastomer is an elastic material, the protective covers 3 and 8 are unlikely to shift out of position when pulled and fitted into the housings 20 and 70.

[0099] By molding the protective covers 3 and 8 as a single part, the manufacturing costs of the printing devices 1 and 6 can be reduced.

[0100] Since the outward surfaces 38 of the protective covers 3, 8 are positioned outside the housings 20, 70 relative to the top surfaces 25, 75, the protective covers 3, 8 can protect the top surfaces 25, 75.

[0101] The protective covers 3, 8 do not interfere with the opening and closing of the opening and closing covers 10, 60, so there is no need to remove them when attaching the label tape T, and the label tape T can be attached smoothly.

The front-to-rear direction of the top surface is an example of the "first direction" of the present invention.
