DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid opening / closing structure, and more particularly to a lid opening / closing structure which can be freely opened and closed with respect to a storage portion for a cutter, a battery and the like formed in an electronic device main body.

[0002]

2. Description of the Related Art Conventionally, a lid, which cannot be easily opened and closed, is formed at a paper discharge port of a facsimile or a printer, and can be opened and closed at the time of maintenance and inspection of an opening in which a cutter is disposed. There are known lids for opening and closing a closed lid and a battery accommodating section in which batteries can be replaced.

[0003] When these lids are easily opened and closed, the internal equipment breaks down, when a blade is mounted inside, a finger or the like is injured, or when a battery is stored. It is assumed that children accidentally swallow this. Particularly in recent years, safety awareness in product design has been increasing, and measures against these issues are not only effective in ensuring safety, but also very effective in selling products with such measures. Sales point.

FIGS. 3 and 4 are views showing a conventional lid opening / closing structure, FIG. 3 is a perspective view thereof, and FIG. 4 is a plan view thereof. In FIG. 3, the lid 60 is openable and closable with respect to the main body 70. To open the lid 60, the lid 60
According to the arrow 62 indicating the release direction (first movement direction) of the lid 60 formed in the above, a finger or the like is brought into contact with the groove 64 to slide the lid 60. When the lid 60 is slid in the direction of the arrow 62, the engagement state of the engagement claw 66 of the lid 60, which has been engaged with the engagement hole 72 (see FIG. 4) of the main body 70, is released.
0 is in the openable state.

[0005]

The conventional lid opening / closing structure is as follows.
First, the first direction (generally parallel to the main surface of the lid)
, The lid is lifted and opened after the first engagement state is released, and the procedure is reversed in closing the lid. 3 and 4, when a force in the direction of arrow 62 acts on the lid 60, the lid 60 is opened. Therefore, the finger holding the main body 70 contacts the lid 60 during use, and the arrow 62
When the force is applied in the direction, the lid 60 slides easily, and the engagement state with the main body 70 is released. At this time,
The user is not conscious of opening the lid 60 (lid 6
0 is not about to be opened), so even if the lid 60 is opened, this is often not noticed. As a result, the user will notice that the lid 60 is opened only when the finger or the like comes into contact with the blades or electronic components housed therein to injure the user or the main body 70 breaks down. In addition, when the lid 60 is left in an openable state, it is impossible to prevent a child or an infant from opening the lid 60 and taking out the battery if the battery is stored therein and swallowing it.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a lid opening / closing structure which is not easily opened by a user's unconscious opening operation. The present invention provides a lid opening / closing structure capable of effectively preventing an accident such as injury by touching an internal mechanism or accidental swallowing of a child or infant when a battery is stored. .

[0007]

In order to solve the above-mentioned problems, a lid opening / closing structure according to the present invention includes a first main body side engaging portion which moves and engages in a first direction and a first main body side engaging portion. A lid-side engaging portion, a second main-body-side engaging portion and a second lid-side engaging portion that move and engage in a direction orthogonal to the first movement direction.

[0008]

When the user opens the lid, the user first releases the engagement between the second main body side engaging portion and the second lid side engaging portion, and then releases the first main body side. The state of engagement between the engaging portion and the first lid-side engaging portion is released. The movement direction for releasing the first engagement state and the movement direction for releasing the second engagement state are selected to be orthogonal to each other.

Conversely, closing the lid requires a procedure reverse to that at the time of opening. First, after the first body-side engaging portion and the first lid-side engaging portion are engaged, The second body portion side engaging portion and the second lid portion side engaging portion are engaged.

[0010]

According to the present invention, when the lid is opened, three actions are required to lift the lid after releasing both the first engagement state and the second engagement state.
The problem of opening the lid by mistake can be effectively eliminated. As a result, a finger or the like accidentally comes into contact with the lid during use, and the lid is opened without the user's consciousness, the internal equipment is damaged, the finger or the like touches the internal mechanism, and the user is injured. When a battery is mounted, it is possible to prevent problems such as dropping out of the battery and accidental swallowing of the dropped battery by a child or the like.

[0011]

FIG. 1 is a perspective view showing an embodiment of a lid opening / closing structure according to the present invention. In FIG. 1, the lid 10 is detachable to open and close an opening 22 formed in the main body 20. The lid 10 is formed with an engagement claw 12 (first engagement means) and an engagement protrusion 14 (second engagement means). An arrow 16 indicating a sliding direction (first moving direction) for releasing the engaging claw 12 is provided on the main surface of the lid 10.
And a groove 1 for contacting a finger when sliding the lid 10
8 are formed.

The main body 20 has an engaging hole 24 (first engaging means) for engaging with the engaging claw 12 of the lid 10 and an engaging concave portion 26 (for engaging with the engaging projection 14 of the lid 10). (Second engagement means). An auxiliary groove 28 for releasing the engagement between the engagement protrusion 14 and the engagement recess 26 is formed near the engagement recess 26. The auxiliary groove 28 has a shape into which a coin or the like can be inserted.

In the embodiment shown in FIG. 1, when closing the lid 10, the lid 10 is
Into the engagement hole 24 of the main body 20 to be temporarily engaged, and slid in the direction opposite to the arrow 16 (first movement direction). The lid 10 is completely slid in the first movement direction and the engagement claw 12
When the cover 10 is rotated and pushed down in the downward direction (second movement direction) in a state where the engagement holes 24 are completely engaged with the engagement holes 24, the engagement protrusions 14 And the lid 10 is completely closed.

Next, in order to open the lid 10, first, a coin or the like is inserted into the auxiliary groove of the main body 20 and twisted, so that the lid 10 is slid upward in the drawing (second movement direction). Then, the engagement state between the engagement protrusion 14 and the engagement recess 26 of the main body is released. With the lid 10 thus lifted in the second movement direction, a finger is brought into contact with the groove 18 of the lid 10 and the lid 10 is slid in the direction of the arrow 16 (first direction) to thereby engage the engaging claw 12 and the main body. 20 is released from the engagement hole 24. After the first and second engagement states are released, the lid 10 is opened by lifting the lid 10.

Here, the releasing direction of the engaging claw 12 (first moving direction) and the releasing direction of the engaging projection 14 (second moving direction) are selected to be orthogonal to each other. As a result, even if a force in the first movement direction acts on the lid 10 by mistake,
The second engagement state is not released. Further, even if a force in the second movement direction acts on the lid 10, the first engagement state is not released. Therefore, even if a finger or the like accidentally comes into contact with the lid 10 during use and a force for sliding (moving) the lid 10 in an arbitrary direction acts, one of the engagement states is maintained and released. The lid 10 does not open accidentally.

Although nothing is shown inside the opening 22 in FIG. 1, the lid 10 cannot be opened by the two-way engagement means even if electronic components such as a cutter or a motor such as a paper cutter are mounted. Therefore, the lid 10 is accidentally opened to expose the inside, thereby preventing an accident such as injury or failure. In addition, even when a battery is stored inside,
0 does not open easily, so that children or infants may accidentally
To prevent accidents of swallowing batteries.

FIG. 2 shows another embodiment of the present invention, in which a lid 30 is detachably provided at an end of a main body 40.
The lid 30 is formed in an L-shaped cross section, and has an engagement claw 32 (first engagement portion) formed at one end (L-shaped portion long side) of the main surface. An engagement protrusion 3 is provided at the short side end of the L-shaped portion.
4 (second engagement means) are formed. Similarly to the embodiment of FIG. 1, the main surface of the lid 30 has an arrow 36 indicating a direction (first movement direction) for releasing the engagement state of the engagement claw 32.
In addition, a groove 38 is formed in a portion where a finger contacts when the lid 30 is moved (slid) in the first direction.

The main body 40 has an engaging hole 44 (first engaging portion) that engages with the engaging claw 32 of the lid 30, and an engaging concave portion 46 (which engages with the engaging protrusion 34 of the lid 30). (A second engaging portion). In addition, in the intermediate portion between the engagement concave portions 46, 46,
An auxiliary groove 48 is formed to assist in lifting the lid 30 upward (second movement direction) in the figure, and the auxiliary groove 48 has a shape into which coins and the like can be inserted. The opening and closing operation of the lid 30 in FIG.
The operation is almost the same as the opening / closing operation, and the description is omitted.

The lid opening / closing structure according to the present invention is different from the prior art shown in FIGS. 3 and 4 in that even if one of the first and second engagement states is erroneously released, the remaining other engagement state is achieved. Since the state is maintained, the lid cannot be opened, and as a result, the problem of inadvertently opening the lid can be avoided.

In the lid opening / closing structure according to the present invention, the direction in which the first engagement state is released and the direction in which the second engagement state is released are selected to be orthogonal to each other. The engaged state is not released at the same time. For this reason, it is impossible for the user to open the lid without being conscious of “opening the lid”, and as a result, the user does not accidentally open the lid unconsciously.

In the embodiments shown in FIGS. 1 and 2, the case where the lid is separated from the main body has been described as an example.
A guide rail is formed in the main body, and an engaging member that engages with the guide rail and is slidable in the guide rail is provided in the lid, so that the lid is held by the main body even in the open state. The present invention is also applicable to an opening / closing structure of a lid having a structure.
