That is, in the embodiment, the printing apparatus 1 is a roll paper printer that prints on recording paper pulled out from roll paper. Note that the printing apparatus 1 may be another type of printing apparatus that prints on continuous paper other than slip sheets and roll paper, instead of the roll paper printer. Also, the print medium may be cut paper, continuous paper, or other medium instead of roll paper.

As shown in FIG. 1 , the printing apparatus 1 includes a printing apparatus main body 3 , an opening/closing cover 8 , and a lock mechanism LK that fixes the printing apparatus main body 3 and the opening/closing cover 8 .

The printing apparatus main body 3 includes a box-shaped case main body 6, a roll paper housing section 7 for housing roll paper, a printing mechanism for printing an image on recording paper, and the like. In addition to these, the printing apparatus main body 3 may be configured to include other members, other mechanisms, other devices, and the like. As an example, the printing mechanism is
It includes a thermal printhead with a plurality of heating elements arranged side by side.

The opening/closing cover 8 is a cover for opening or closing the roll paper compartment 7 . In the example shown in FIG. 1, the opening/closing cover 8 closes the roll paper inlet 7a of the roll paper compartment 7 from the front. The opening/closing cover 8 is fixed to the printer main body 3 by the lock mechanism LK when the roll paper compartment 7 is closed. As a result, the printing apparatus 1 can prevent the opening/closing cover 8 from spontaneously opening the roll paper compartment 7 . Further, in this example, the opening/closing cover 8
is provided between the front lower end of the case body 6 and the discharge port 5 . The opening/closing cover 8 may be provided with a transport roller for transporting the recording paper pulled out from the roll paper. Further, the opening/closing cover 8 may constitute a cutting mechanism for cutting the printed recording paper when the opening/closing cover 8 closes the roll paper compartment 7 . In this case, one of the printing apparatus main body 3 and the opening/closing cover 8 is provided with a first blade, which is a movable blade for cutting the recording paper, and the other of the printing apparatus main body 3 and the opening/closing cover 8 is provided with the first blade. and a second blade that is a fixed blade for cutting the recording paper. Further, the printing apparatus main body 3 may be provided with a transport roller, and the opening/closing cover 8 may include
A printing mechanism may be provided.

The lock mechanism LK is a mechanism for fixing the open/close cover 8 to the printer main body 3 when the roll paper compartment 7 is closed by the open/close cover 8 . The lock mechanism LK may be any mechanism as long as it can fix the opening/closing cover 8 to the printer main body 3 in this case. Note that the lock mechanism LK may be configured to be provided in the printer main body 3.
A configuration provided in the opening/closing cover 8 may be employed. Further, the lock mechanism LK may be provided at one end in the X-axis direction of the printer main body 3 or the opening/closing cover 8, or may be provided at both ends in the X-axis direction.

The printer case 4 is a box-shaped external case formed by the case main body 6 of the printer main body 3 and the first surface M1 that is the external surface of the opening/closing cover 8 . The printer case 4 may be any case as long as it accommodates the printer main body 3 . In the example shown in FIG. 1, the printer case 4 is a rectangular parallelepiped case as a whole. In addition, printer case 4
may be any other shape instead of the rectangular parallelepiped shape. The printer case 4 is provided with a discharge port 5 for discharging the recording paper. In the example shown in FIG. 1, the discharge port 5 is provided at a position closer to the upper end of the front surface of the printer case 4 than to the center of the front surface of the printer case 4 .

The opening/closing cover 8 also has an operation lever 9 . The operation lever 9 is a member that releases the fixing of the opening/closing cover 8 to the printing apparatus main body 3 by the lock mechanism LK when operated in a predetermined first direction. Here, the first direction may be any direction. In the following, as an example, the case where the first direction is the negative direction of the Z axis, that is, the downward direction will be described.
In this case, in the first direction, when the opening/closing cover 8 closes the roll paper compartment 7,
This direction is parallel to the first surface M<b>1 on the opposite side of the surface of the opening/closing cover 8 that faces the roll paper compartment 7 . Note that the first direction may be another direction instead of the negative direction of the Z-axis. Also, the first direction may be changed to a direction parallel to the first surface M1 and may be a direction non-parallel to the first surface M1. Note that the operation lever 9 is provided on the case main body 6 instead of the configuration provided on the open/close cover 8 .
may be a configuration provided for. Also, the first direction may be referred to as the release direction of the opening/closing cover 8 .

The operating lever 9 has a first operated portion 91 . The first operated portion 91 is a portion provided at an end of the operating lever 9 opposite to the lock mechanism LK. When the roll paper compartment 7 is closed by the open/close cover 8 , the parts of the operation lever 9 other than the first operated portion 91 are located in the space surrounded by the printer case 4 and the open/close cover 8 . Because it is located in , it is almost invisible from the outside. Therefore, the first operated portion 91 is a portion of the operation lever 9 that receives an operation from the user in this case. In the example shown in FIG. 1 , a first operated portion 91 of the operating lever 9 is provided on the right side of the opening/closing cover 8 . The opening/closing cover 8 of the first operated portion 91 closes to the roll paper storage portion 7 .
is closed, the second surface M2 is included in the virtual surface including the first surface M1. Note that the second surface M2 may be configured not to be included in the virtual surface including the first surface M1.

When the first operated portion 91 of the operating lever 9 is operated in the first direction, the lock mechanism LK
The fixing of the opening/closing cover 8 to the printing apparatus main body 3 by is released. When the fixing is released, the opening/closing cover 8 becomes rotatable at the lower end portion of the opening/closing cover 8 around a rotation axis extending parallel to the X-axis. The opening/closing cover 8 closes the roll paper storage section 7 in a lying posture against the front surface of the printer case 4 . On the other hand, the opening/closing cover 8 opens the roll paper compartment 7 while standing upright with respect to the front surface of the printer case 4 . In the example shown in FIG. 1 , the opening/closing cover 8 closes the roll paper compartment 7 in a prostrate position against the front surface of the printer case 4 .

Here, the first operated portion 91 has a first portion MK indicating a second direction different from the first direction. The first portion MK may be separate from the first operated portion 91 or integrated with the first operated portion 91 . When the first portion MK is separate from the first operated portion 91, the first portion MK is, for example, a sheet-like member such as a sticker on which information indicating the second direction is drawn, and is attached by an adhesive or the like. It is fixed with respect to the first part MK. On the other hand, when the first portion MK is integrated with the first operated portion 91, the first portion MK is a part of the first operated portion 91, for example. In the example shown in FIG. 1 , the first portion MK is integrated with the first operated portion 91 .

The second direction may be any direction as long as it is different from the first direction. In the following, as an example, a case where the second direction is opposite to the first direction will be described. In this case, the second direction is the positive direction of the Z axis, that is, the upward direction. Also, in this case, the second direction is
This direction is parallel to the first surface M1 when the opening/closing cover 8 closes the roll paper compartment 7 . Note that the second direction may be another direction different from the first direction instead of the positive direction of the Z axis. Also, the second direction may be changed to a direction parallel to the first surface M1 and may be a direction non-parallel to the first surface M1. In the example shown in FIG. 1, the second direction is indicated by the remaining one vertex of the three vertices of the isosceles triangle other than the two vertices sandwiching the base. More specifically,
The second direction is indicated by the direction from the base of this isosceles triangle perpendicular to the vertex. The triangle indicating the second direction may be another triangle such as an equilateral triangle instead of the isosceles triangle. Also, the second direction may be referred to as the non-release direction of the opening/closing cover 8 .

Such a first portion MK is provided on a surface of the first operated portion 91 that is visible from the outside when the opening/closing cover 8 closes the roll paper accommodating portion 7 . In the example shown in FIG. 1, the first portion MK is provided on the second surface M2. As a result, the printing device 1
To make a person who does not need to operate the printer 1 misunderstand the operation for opening the roll paper storage part 7 as the operation to move the operation lever 9 in the second direction via the first operated part 91. - 特許庁be able to. As a result, the printer 1 does not complicate the configuration of the entire system including the printer 1, and can inexpensively prevent the roll paper container 7 from being opened by an unintended operation of the operation lever 9. can be done. The reason why it is possible to inexpensively prevent the roll paper compartment 7 from being opened due to an unintended operation of the operation lever 9 is, for example, that the operation lever 9 uses a member that receives an operation from the user as the first Such misrecognition can be caused by replacing a member having a portion indicating a direction with the first operated portion 91 . Here, FIGS. 2 and 3 are enlarged views of the first operated portion 91 shown in FIG. The arrows shown in FIGS. 2 and 3 indicate the first direction and the second direction, respectively.

As described above, the printing device 1 is provided with the printing device main body 3 and the printing device main body 3,

The operation lever 9 includes a lock mechanism LK fixed to the main body 3 and an operation lever 9 for releasing the fixation of the opening/closing cover 8 to the printer main body 3 by the lock mechanism LK when operated in the first direction. has a first portion MK showing a second direction different from the first direction. As a result, the printing apparatus 1 can inexpensively suppress the opening of the roll paper accommodation section 7 due to an unintended operation of the opening/closing cover 8 without complicating the configuration of the entire system including the printing apparatus 1.例文帳に追加can be done.

Note that the first portion MK may have a configuration included in the opening/closing cover 8 instead of the configuration included in the first operated portion 91 . In this case, the first part MK is located on the first surface M1, for example.
Also, the first part MK may be a structure that the case main body 6 has. In this case, the first portion MK is positioned on the outer surface of the case body 6 .

Further, the first portion MK may be a portion indicating the second direction with an arrow, a portion indicating the second direction with a figure of another shape, or a portion indicating the second direction with a character. Alternatively, it may be a portion that indicates the second direction by another method. Also, the first part MK
may be a display panel. In this case, the first portion MK indicates the second direction by means of images, characters, etc. displayed on the display panel. Also, the first part MK may be a plurality of LEDs (Light Emitting Diodes). In this case, the first portion MK indicates the second direction by the light pattern of the plurality of LEDs. For example, in this case, these multiple L
ED is arranged in the shape of an arrow indicating the second direction as the first portion MK.

Further, when the operation lever 9 is provided on the case main body 6, the unlocking of the opening/closing cover 8 from the printing apparatus main body 3 by the lock mechanism LK may be performed via wireless communication.

<Modification 1 of Embodiment>
Modification 1 of the embodiment will be described below. In Modification 1 of the embodiment, the shape of the first operated portion 91 is different from that of the first operated portion 91 according to the embodiment. Therefore, in the modified example of the embodiment, the first operated portion 91 according to the first modified example of the embodiment will be referred to as a first operated portion 91A. In addition, in the modified example 1 of the embodiment, the same reference numerals are assigned to the same components as in the embodiment, and the description thereof is omitted.

FIG. 4 is a perspective view showing another example of the appearance of the printing apparatus 1. As shown in FIG. 5 and 6 are enlarged views of the first operated portion 91A shown in FIG. The arrows shown in FIGS. 5 and 6 indicate the first direction and the second direction.
showing each of the directions.

The first operated portion 91A has a guiding portion that guides the operation of the first operated portion 91A by a person who intends to operate the first operated portion 91A to be an operation in the second direction.

In the example shown in FIG. 4, the first operated portion 91A includes the inclined portion SL as such a guiding portion.
have The sloped portion SL is a portion of the first operated portion 91A, and is inclined toward the roll paper accommodating portion 7 as it approaches the end of the first operated portion 91A that is opposite to the second direction. It is a portion that is slanted in the direction of separation. As a result, the printing apparatus 1 allows a person who does not need to operate the printing apparatus 1 to perform the operation for opening the roll paper compartment 7 in the first direction.
This can be more reliably misidentified as the operation of moving the operating lever 9 in the second direction via the operated portion 91 . This is because a person who sees the first operated portion 91A psychologically perceives the direction in which the first operated portion 91 is operated in the direction in which the height of the inclined portion SL is lowered with respect to the first surface M1. This is because there is a tendency to That is, a person who intends to operate the first operated portion 91A should psychologically operate the first operated portion 91 in a direction in which the height of the inclined portion SL relative to the first surface M1 becomes lower. and end up. As a result, the printer 1 can more reliably prevent the roll paper compartment from being opened by an unintended operation of the opening/closing cover without complicating the configuration of the entire system including the printer 1. can be done.

In addition, compared with the end portions of the first operated portion 91A other than the end portion in the direction opposite to the second direction, the sloped portion SL is more difficult for a person to operate the first operated portion 91A. It has a structure that makes it easy to hook your finger. For this reason, when a person who is going to operate the first operated portion 91A tries to operate the first operated portion 91A, he/she psychologically hooks his/her finger on the inclined portion SL and pushes the first operated portion 91A forward. You are trying to operate in two directions. As a result, the printer 1
Without complicating the configuration of the entire system including the opening and closing cover, it is possible to more reliably prevent the roll paper storage section from being opened by an unintended operation of the opening/closing cover.

Note that the first portion MK may be positioned on the surface of the inclined portion SL opposite to the roll paper accommodating portion 7, or may be positioned on the second surface M2. Alternatively, it may be positioned on another surface of the surfaces of the first operated portion 91A that can be seen from the outside. In the example shown in FIG. 4, the first portion MK is positioned on the surface of the inclined portion SL on the side opposite to the roll paper accommodating portion 7 .

Further, in the first operated portion 91A, the position where the inclined portion SL is provided is the first operated portion 91A instead of the end opposite to the second direction among the ends of the first operated portion 91A. Other positions on the portion 91 may be used. Further, instead of the configuration in which the height relative to the first surface M1 decreases in the second direction, the slope of the sloped portion SL is configured to decrease in a direction other than the first direction. good too.

Further, the first operated portion 91A may have a configuration in which a portion having another shape indicating the second direction is provided as a guiding portion instead of the inclined portion SL. For example, the guide portion may be a grasping portion, a handle portion, a pinching portion, or the like having a structure that facilitates application of force in the second direction. Further, the first operated portion 91A may have a dummy key portion such as a dummy imitating a dial-type key or a dummy imitating a keyhole instead of the guiding portion.

As described above, in the printing apparatus 1 , the closer to the end portion of the first operated portion 91</b>A in the direction opposite to the second direction, the more inclined in the direction away from the roll paper accommodating portion 7 . It has an inclined portion SL, and the first portion MK is located on the surface of the inclined portion SL on the side opposite to the roll paper accommodating portion 7 . As a result, the printer 1 does not complicate the configuration of the entire system including the printer 1, and can more reliably prevent the roll paper container from being opened by an unintended operation of the opening/closing cover. can be done.

<Modification 2 of Embodiment>
Modification 2 of the embodiment will be described below. In the modification 2 of the embodiment, the operating lever 9
has a second operated portion 91B in addition to the first operated portion 91A. In addition, in Modification 2 of the embodiment, the same reference numerals are assigned to the same components as in the embodiment and Modification 1 of the embodiment, and the description thereof is omitted.

FIG. 7 is an enlarged view of the first operated portion 91A and the second operated portion 91B when the printing apparatus 1 includes the operating lever 9 having the second operated portion 91B.

As shown in FIG. 7, in Modification 2 of the embodiment, the opening/closing cover 8 has a second portion 81 that faces the third surface M3 on the side of the roll paper compartment 7 among the surfaces of the inclined portion SL. The second operated portion 91B is a member positioned between the inclined portion SL and the second portion 81, and is a member that receives an operation from the user. In other words, a second operated portion 91B that receives an operation from the user is provided between the inclined portion SL and the second portion 81 .

Between the inclined portion SL and the second operated portion 91B, as shown in FIG. 8, there is an elastic member SP that biases the second operated portion 91B toward the second portion 81 with an elastic force. is provided. FIG. 8 is a diagram showing an example of the positional relationship among the inclined portion SL, the second operated portion 91B, and the elastic member SP. Note that FIG. 8 shows cross sections of the first operated portion 91A and the second operated portion 91B in order to clearly show this positional relationship.

The elastic member SP is, for example, a coil spring. The elastic member SP may be a spring such as a leaf spring, or an elastic body such as rubber, instead of the coil spring. The elastic member SP is positioned between the inclined portion SL and the second operated portion 91B, and
B is biased toward the second portion 81 by an elastic force. As a result, the second operated portion 91B
is operated to approach the inclined portion SL by a human hand, when the human hand leaves the second operated portion 91B, it approaches the second portion 81 and contacts the second portion 81 again. do.

Here, the second portion 81 has a concave portion that fits with a portion of the second operated portion 91B. In other words, the second operated portion 91B has a convex portion that fits into the concave portion of the second portion 81 . When the second operated portion 91B is in contact with the second portion 81, the concave portion of the second portion 81 has
The convex portion of the second operated portion 91B is fitted. Therefore, in this case, the operating lever 9 cannot be operated in the first direction. On the other hand, when the second operated portion 91B is not in contact with the second portion 81, that is, when the second operated portion 91B is brought closer to the inclined portion SL against the elastic force of the elastic member SP, the operating lever 9 is operable in the first direction.

9, the second operated portion 91B shown in FIG. 8 is inclined to the inclined portion SL against the elastic force of the elastic member SP.
FIG. 11 is a diagram showing an example of the positional relationship among the inclined portion SL, the second operated portion 91B, and the elastic member SP when the slanted portion SL is brought closer to the . A recess C1 shown in FIG. 9 is an example of a recess that the second portion 81 has. A convex portion C2 illustrated in FIG. 9 is an example of a convex portion included in the second operated portion 91B. In addition, Fig. 8
In order to avoid complication of the drawing, the concave portion C1 and the convex portion C2 are omitted. 10 shows the first operated portion 91A and the second operated portion 91B when the second operated portion 91B shown in FIG. 7 is brought closer to the inclined portion SL against the elastic force of the elastic member SP. It is an enlarged view.

In the printing apparatus 1, the operating lever 9 cannot be operated in the first direction unless the second operated portion 91B is brought closer to the inclined portion SL. Therefore, the printing apparatus 1 further reliably prevents the roll paper storage section from being opened by an unintended operation of the opening/closing cover without complicating the configuration of the entire system including the printing apparatus 1. be able to.

As described above, in the printing apparatus 1, the opening/closing cover 8 has the second portion 81 facing the third surface M3 on the side of the roll paper accommodating portion 7 among the surfaces of the inclined portion SL. A second operated portion 91B that receives an operation from the user is provided between the two parts 81, and the second operated portion 91B is provided between the inclined portion SL and the second operated portion 91B. An elastic member SP is provided to bias the second portion 81 with an elastic force, and the operating lever 9 causes the second operated portion 91B to approach the inclined portion SL against the elastic force of the elastic member SP. In this case, it is in a state in which it is possible to operate in the first direction. As a result, the printing apparatus 1 does not complicate the configuration of the entire system including the printing apparatus 1, and more reliably prevents the roll paper compartment from being opened by an unintended operation of the opening/closing cover. be able to.

In place of the configuration described above, the second operated portion 91B has a state in which the first operated portion 91A can be operated in the first direction, and a state in which the first operated portion 91A cannot be operated in the first direction. Any other configuration that can be switched between and may be used. For example, the second operated portion 91B may be a button provided on the opening/closing cover 8 . In this case, when this button is pressed, the first operated portion 91A becomes operable in the first direction.

Further, the first operated portion 91A of the printing apparatus 1 according to Modification 2 of the embodiment may be configured without at least one of the first portion MK and the inclined portion SL. Even in this case,
Since the printing apparatus 1 is provided with the second operated portion 91B, the roll paper storage section 7 can be opened by an unintended operation of the operation lever 9 without complicating the configuration of the entire system including the printing apparatus 1. It is possible to inexpensively suppress the opening.

As described above, the printing apparatus according to the embodiment includes a printing apparatus main body, a roll paper storage unit that can store roll paper, and a roll paper storage unit that is provided in the printing apparatus main body, and opens or closes the roll paper storage unit. an open/close cover, a lock mechanism for fixing the open/close cover to the printing apparatus main body when the roll paper storage section is closed by the open/close cover, and a printing apparatus main body of the open/close cover by the lock mechanism when operated in the first direction. an operation lever for releasing the fixation to the device, the operation lever having a first portion indicating a second direction different from the first direction.
