Abstract

PURPOSE:To allow an operating member to be temporarily hooked surely, separating sufficiently from the equipment body and pull out the operating member with a weak resistance force, when the lock for the equipment body is released, as for the constitution in which the operating member is installed in a demountable manner on the electronic equipment body. CONSTITUTION:An operating member 13 is hooked with a nose part 12 by a hook part 17 and turned in the alpha direction, and installed on the noise part 12 and locked. When the lock is released, the operating member 13 is projectingly urged in the beta direction, and at the time point where the operating member 13 turns by a prescribed angle, the operating member 13 is temporarily hooked by an elastic hooking member 41 utilizing leaf spring. When the operating member 13 is pulled out from a temporary hooking position, the pulling-out can be carried out with the less resistance force through the elastic deformation of the elastic hooking member 41. Since the distance H between the elastic hook member 41 and the hook part 17 is less than the half of the width dimension I of the operating member 13, the operating member 13 turns sufficiently largely in the beta direction and temporarily hooked, even if the dimension F of the elastic hook member 41 is short.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device, such as an on-vehicle audio device, in which an operating member is removably attached to a device body, and particularly, an operation for detaching the operating member from the device body. The present invention relates to an operation device for an electronic device that allows a member to be easily picked up by hand.

[0002]

2. Description of the Related Art An electronic device is usually provided with an operation surface and various operation buttons are arranged on the operation surface. However, some electronic devices have an operation member for controlling the device body. Some are removable from the device itself. FIG. 7 is a partial plan view showing an operating device for an in-vehicle audio device as an example of an operating device for an electronic device of this type.
FIG. 8 is an enlarged plan view of a portion VIII in FIG.
The device body 1 has a metal chassis 2 embedded in a console panel in front of a front seat of an automobile, and a nose portion 3 provided in front of the metal chassis 2 which is a decorative portion made of a resin material.
With the chassis 2 embedded in the console panel, the nose portion 3 substantially coincides with the front surface of the console panel. A concave portion 3a is formed on the front surface of the nose portion 3, and the concave portion 3a is formed.
The operation member 4 is detachably mounted therein.

A front surface of the operating member 4 is an operating surface 4a, and various operating buttons 5, 5, ..., A liquid crystal display panel and the like are arranged on the operating surface 4a. The operation member 4 and the front surface of the nose portion 3 are electrically connected by a detachable connector. For example, when the operation member 4 is detached from the device body 1 and carried while parking, the internal mechanism and the internal circuit of the device body 1 left in the vehicle become inoperable, which causes the device body to operate. 1 can be prevented from being stolen from a car. As for the mounting structure of the operating member 4 and the nose portion 3, first, at the right end portion of FIG. 7, the latching protrusion 3b provided on the nose 3 and the latching recessed portion 4b formed on the operating member 4 are unevenly latched. Has been done. As enlargedly shown in FIG. 8, a lock groove 4c is formed on the left side surface of the operation member 4 in the drawing. Nose part 3
The lock claw 6 projects from the inner surface on the left side of the figure, and the lock claw 6 is elastically biased in the projecting direction. Also nose part 3
A lock release button 7 is provided on the front left side of the figure,
When the lock release button 7 is pressed, the lock claw 6 retracts to the left in the drawing and comes out of the lock groove 4c.

In the mounting operation of the operating member 4, first, the hooking concave portion 4b is hooked on the hooking protrusion 3b, and the operating member 4 is rotated in the α direction with the hooking portion serving as a fulcrum, and the concave portion of the nose portion 3 is rotated. Install in 3a. At this time, the lock groove 4c formed on the left side surface of the operating member 4 in the drawing and the lock claw 6 are fitted to each other, and the operating member 4 is attached to the nose portion 3 without being separated. When the operation member 4 is taken out from the device body 1, the lock release button 7 is pressed. As a result, the lock claw 6 is disengaged from the lock groove 4c. A protrusion urging member for urging the operating member 4 in the detaching direction is provided in the concave portion 3a of the nose portion 3, and when the engagement between the lock claw 6 and the lock groove 4c is released, the operating member 4 is moved to the above-mentioned position. Due to the force, it pops out so as to rotate in the direction indicated by β in FIG. 7. Hold this operating member 4 by hand,
The operation member 4 can be taken out from the device body 1 by releasing the engagement between the engagement protrusion 3b and the engagement recess 4b.

[0005]

However, in the above-mentioned conventional operating device, when the lock release button 7 is pressed, the operating member 4 and the nose portion 3 are completely disengaged from each other on the left side in the figure. If 4 is not grasped by hand, the operating member 4 will separate from the nose part 3 and will fall as it is toward the floor surface. Therefore, for example, it is necessary to hold the operation member 4 with the right hand and press the unlock button 7 with the left hand.
It is inconvenient to handle. As a means for preventing this, for example, as shown in FIG. 8, the provisional latching protrusion 8 located in front of the lock pawl 6 on the left inner surface of the nose portion 3 in the figure.
Is provided. When the locking claw 6 comes out of the locking groove 4c, the lock of the operating member 4 is released, and the operating member 4 is rotated in the β direction by the projecting biasing member, the locking groove 4c of the operating member 4 is temporarily locked. The operation member 4 is temporarily hooked at the position where it is caught by the projection 8. At this time, when the operating member 4 is grasped by hand and pulled forward, the temporary locking projection 8 and the lock groove 4c are forcibly released from each other, and the operating member 4 is completely removed from the nose portion 3.

However, as shown in FIG.
When the nose portion 3 is integrally formed with resin by protruding from the nose portion 3, after the lock groove 4c is temporarily hooked by the temporary hooking projection 8,
When the operating member 4 is grasped and pulled by hand, the resistance force for forcibly releasing the temporary locking of the temporary locking projection 8 and the lock groove 4c becomes very large, and it is great for taking out the operating member 4. You need power. In order to reduce this resistance force, the protrusion dimension A of the temporary locking projection 8 may be reduced. However, in this case, when the operating member 4 rotates in the β direction, the temporary locking projection 8 may not be caught in the lock groove 4c, and the temporary locking at the time when the operating member 4 rotates in the β direction occurs. It may not be possible to stop. Further, since the depth B of the recess 3a of the nose portion 3 is not so large, the lock claw 6 and the temporary hooking projection 8
The distance C between and is also very short. Therefore, the lock claw 6
The rotation angle in the β direction of the operating member 4 is very small until the provisional locking projection 8 engages with the lock groove 4c after the slipping out of the lock groove 4c. Therefore, the movement of the operating member 4 to the temporary locking position after pressing the lock release button 7 is small, and the person who presses the lock release button 7 may not be able to reliably recognize the lock release. In addition, since the temporarily locked operation member 4 does not project to a position where it can be easily grasped by hand, it is inconvenient to handle the operation member 4 when taking it out.

The present invention has been made to solve the above-mentioned conventional problems, and makes it possible to take out an operating member unlocked from the device body with a light resistance force, and compare the unlocked operating member to the device body. It is an object of the present invention to provide an operating device for an electronic device, which is rotated by an extremely large angle to be temporarily hooked.

[0008]

SUMMARY OF THE INVENTION The present invention comprises a device body,
In an operating device for an electronic device having an operation member detachably attached to the device body, a latching part for engaging one edge of the operating member with the device body, and the operating member are attached to the device body. When the lock mechanism is engaged, the lock mechanism that engages the operation member and the device body at a position away from the hooking portion, the lock release operation body that releases the engagement by the lock mechanism, and the engagement by the lock mechanism are released. A protruding biasing member that biases the operating member in a direction away from the device body when the operating member is mounted at a position between the locking portion of the device body and the lock mechanism. An elastic latching member is provided that is elastically latched to the operating member when the operating member is disengaged by the locking mechanism and the operating member is projectingly biased by the projecting biasing member. It is also characterized by It is.

Here, one example of the elastic hooking member entering the operating member is that the elastic hooking member enters the recess or groove formed in the operating member, or inside the recording medium insertion port formed in the operating member. It enters into a recess formed continuously or close to the side surface. In addition, one example of being elastically hooked to the operation member is that the operation member is elastically hooked and recessed.

In the above means, an insertion frame whose inside is an insertion passage for the recording medium is formed to project in the main body of the apparatus, and an insertion port communicating with the insertion passage is formed in the operation member, so that the elastic locking member is formed. Is provided in the vicinity of a side surface of the insertion frame facing the hooking portion.

Alternatively, an insertion frame whose inner side serves as an insertion passage for the recording medium is formed in a protruding manner on the device body, and an elastic locking member extending from the device body is provided on the outside of the side surface of the insertion frame facing the locking portion. A leaf spring is provided, and a protection protrusion that covers the tip of the leaf spring is formed on the side surface of the insertion frame, and the operation member has an insertion opening communicating with the insertion passage and the protection protrusion fitted and slid. Is formed, and the leaf spring is
It is elastically locked in this recess.

Here, as an example of the protective projection for covering the tip of the leaf spring, a hooking projection is integrally formed at the tip of the leaf spring extending from the main body of the device, and the free end of the leaf spring is separated from the insertion frame. There is a protective protrusion, against which this free end strikes, to prevent it from moving to.

[0013]

In the first means, one edge of the operating member and the device body are hooked by the hooking portion. When the operating member is pushed toward the device body with the hooking portion as a fulcrum, the operating member and the device body are engaged by the lock mechanism at a position away from the hooking portion, whereby the operating member is moved. It is installed without detaching. At this time, the elastic locking member provided in the device body is the hole formed in the operation member,
It enters into a recess formed in the operation member or a recess continuous or adjacent to the side of the recording medium insertion opening formed in the operation member. When the lock release operation body releases the engagement between the operation member and the device body by the lock mechanism, the operation member is rotated by the protrusion urging force of the protrusion urging member in a direction away from the device body with the hook portion as a fulcrum. Move. At this time, the elastic locking member is elastically tentatively locked to the operating member, elastically ruggedly locked, or elastically ruggedly fitted so that the operating member is tentatively locked at that position. To be done.

After that, when the operating member is grasped by hand and pulled forward, the elastic temporary locking between the elastic locking member and the operating member is released. When the operating member is grasped and pulled by hand, the elastic locking member is elastically deformed and the temporary locking with the operating member is released. Therefore, the operating member can be pulled out with a comparatively easy force with a small resistance force. it can.

Further, since the elastic hooking member is located between the hooking portion and the lock mechanism in the device body, even if the elastic hooking member has a short projection distance from the device body,
The operation member is temporarily hooked at a position where it is rotated away from the main body of the device by a sufficient angle. Therefore, it becomes easier to grasp the operating member at the temporary hooking position by hand, and the turning angle of the operating member from the unlocked position to the temporary hooking position is large,
It can be easily recognized that the engagement by the lock mechanism has been reliably released.

In order to sufficiently increase the angle at which the operating member is rotated from the position where it is attached to the main body of the apparatus to the position where it is temporarily locked, the distance between the locking part and the elastic locking member is the same as the locking part. It is preferably half or less of the distance from the lock mechanism. Alternatively, it is preferable that the distance between the hooking portion and the elastic hooking member is half or less of the width dimension of the operating member.

Further, by arranging the elastic hooking member at a position close to the side surface of the insertion frame formed in the main body of the device, which faces the hooking portion, the elastic hooking member can be hooked and recessed. The portion or the concavo-convex fitting portion can be installed in the inner surface of the insertion port of the recording medium of the operation member, or in the concave portion which is continuous with the inner surface or close to the inner surface. Therefore, it is not necessary to specially provide the operation member with a concave portion, a hole, or a groove into which an elastic locking member other than the insertion port is inserted.

Further, by using a leaf spring extending from the main body of the device as the elastic locking member, the elastic locking member can be provided with a simple structure at a low cost. In addition, by forming a protective protrusion on the side of the insertion frame facing the hooking portion to cover the tip of the leaf spring, when the operating member is attached to the device body, there is a problem that the tip of the leaf spring hits the operating member and bends. Can be prevented. Further, by slidingly fitting the protection protrusion into the recess formed in the operation member, the protection protrusion can function as a guide portion of the operation member.

Further, the contact pin of the pin connector 18 comes into contact with the contact terminal of the terminal plate provided on the back surface of the operation member 13. Further, the latching protrusion 41b of the elastic latching member 41 shown in FIG.
After overcoming the latching convex portion 13e on the back side of the vehicle and once deforming to the state shown by the broken line, and overcoming the latching convex portion 13e, the free end 4
1c elastically returns to a state of hitting the receiving portion 12j, and the latching protrusion 41b of the elastic latching member 41 becomes the recess 1 of the operating member 13.
Go into 3c.

Then, the lock groove 24 on the left side surface of the operating member 13 is engaged (fitted) with the lock claw 21a shown in FIG.
Then locked. The operation member 13 is engaged by the engagement by the lock mechanism 20 and the uneven engagement by the engagement portion 17.
Is securely held in the recess 12a of the nose portion 12. When the operation member 13 is taken out, the push button portion 23a of the unlocking operation body 23 protruding from the surface 12g on the left side in the drawing of the peripheral frame of the nose portion 12 is pushed. Unlock operation body 23
When is pushed in the (h) direction, the lock body 21 retracts in the (e) direction due to the sliding between the rear end surface 23b and the inclined surface 21b, and the lock claw 21a is engaged with the lock groove 24 of the operating member 13. The lock mechanism 20 releases the engagement between the operating member 13 and the device body 10. As a result, the operating member 1
3 rotates in the β direction (in front of the device body 10) with the hooking portion 17 in which the hooking protrusion 17a and the hooking recess 17b are fitted in a concavo-convex as a fulcrum. When the operating member 13 rotates by a predetermined angle (about 10 degrees), as shown by the broken lines in FIGS. 2 and 4, the latching protrusion 41b of the elastic latching member 41 and the latching protrusion 13e of the operating member 13 are shown. And are locked, and the operating member 13 is no longer β
Without temporarily turning in that direction (temporary locking) at that position
To be done.

As shown in FIG. 2, the elastic locking member 41 is located between the locking portion 17 and the lock mechanism 20. The distance H between the hook 17 and the elastic hook 41 is less than half the distance I from the hook 17 to the left side surface of the operating member 13. The distance I substantially matches the width dimension of the operating member 13 in the left-right direction, and I substantially matches the distance from the hook 17 to the lock mechanism 20. Due to the ratio I to H of this distance, even if the distance F from the bottom surface 12e of the recess 12a of the nose portion 12 to the latching protrusion 41b of the elastic latching member 41 is short, the operating member 13 is larger in the β direction than before. It will be rotated by an angle and temporarily hooked.
The distance F from the bottom surface 12e to the hooking projection 41b is
It is not more than the depth dimension (width dimension J in the vertical direction in FIG. 2) of the operation member 13. In the embodiment of FIG. 2, the distance G between the left side end of the operating member 13 in the temporarily locked state shown in the figure and the bottom surface 12e of the recess 12a of the nose portion 12 is considerably large, and the rear surface of the operating member 13 is large. The left end portion in the figure is rotated to a position farther from the device body 10 than the surface 12g on the left side in the figure of the peripheral frame of the nose portion 12.

Therefore, the operating member 13 rotated to the temporary hooking position shown by the broken line in FIG. 2 can be easily gripped by hand. Further, since the angle from the position where the operation member 13 is mounted in the recess 12a of the nose portion 12 to the temporary locking position shown by the broken line is large, the person who pushes the push button portion 23a of the unlocking operation body 23 can unlock the lock. Can be surely recognized. As described above, in the above-described embodiment, the hooking protrusion 41 is provided from the bottom surface 12e of the nose portion 12.
Even if the distance F to b is sufficiently shorter than the depth dimension J of the operation member 13, the angle at which the operation member 13 rotates to the temporary locking position can be increased. As described above, in order to sufficiently increase the rotation angle to the temporary locking position, the locking portion 17
From the elastic hooking member 41 to the left side surface of the operating member 13 from the hooking member 17 (or the hooking portion 1).
7 to the lock mechanism 20, or the operating member 1
It is preferable that the width is less than half of the horizontal dimension of 3).

Further, the operating member 13 rotated to the temporary locking position shown by the broken line in FIG. 2 has the locking projection 4 of the elastic locking member 41.
The elastic hooking of 1b allows it to stay securely, and when the lock mechanism 20 is disengaged, the operating member 13 does not separate from the device body 10 and fall to the floor surface. . Moreover, the operation member 1 in the temporary hooking position
When 3 is grasped by hand and pulled out to the front, the elastic hooking member 41 is elastically deformed, and the hooking between the hooking projection 41b and the hooking projection 13e is released by a relatively weak resistance force. Therefore, the operating member 1

[0035]

As described above, in the present invention, when the engagement by the lock mechanism is released and the operating member is separated from the main body of the device, the operating member is elastically temporarily locked by the elastic locking member. Therefore, the operation member is securely held at the temporary hooking position,
Moreover, the resistance force when taking out the operating member is reduced,
The operation member can be taken out with a weak force.

Further, since the elastic hooking member is located between the hooking portion and the lock mechanism in the device body, even if the elastic hooking member has a short projection distance from the device body,
The operation member is temporarily hooked at a position where it is rotated away from the main body of the device by a sufficient angle. Therefore, it becomes easier to grasp the operating member at the temporary hooking position by hand, and the turning angle of the operating member from the unlocked position to the temporary hooking position is large,
It can be easily recognized that the engagement by the lock mechanism has been reliably released.

Further, by arranging the elastic hooking member at a position close to the side surface of the insertion frame formed in the main body of the device, which faces toward the hooking portion, the elastic hooking member is hooked and recessed. The portion or the concavo-convex fitting portion can be installed in the inner surface of the insertion port of the recording medium of the operation member, or in the concave portion which is continuous with the inner surface or close to the inner surface. Therefore, it is not necessary to specially provide the operation member with a concave portion, a hole, or a groove into which an elastic locking member other than the insertion port is inserted.

Further, by using a leaf spring extending from the main body of the device as the elastic locking member, the elastic locking member can be provided with a simple structure at a low cost.

Further, by forming a protective projection on the side surface of the insertion frame facing the hooking portion, the tip of the leaf spring hits the operating member and bends when the operating member is mounted on the device body. You can prevent problems. Further, by slidingly fitting the protection protrusion into the recess formed in the operation member, the protection protrusion can function as a guide portion of the operation member.
