[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small acoustic device such as a portable CD player.

[0002]

2. Description of the Related Art In recent years, the size of CD players has been reduced and the age of users has been reduced, and portable CD players for children have been released.

[0003]

In such a device for children, an operation which is not performed by an adult is often performed. Operate the open / close button on the lid while carrying the CD player, or the open / close button touches the body even if you do not operate it yourself, the lid opens and the CD inside jumps out and scratches It can happen. Therefore, in such a device, it is required to take sufficient safety measures so that an erroneous operation by a child is not hindered.

[0004]

According to the present invention, there is provided a cover having an engaging recess, an engaging claw engaging with the engaging recess of the cover, and an operating arm. An operating member having an engaging member, a shaft portion inserted into the device, and pressing an operating arm of the engaging member; a concave portion into which the shaft portion of the operating member enters; and a weight at one end. When the device is in a substantially horizontal state, the shaft portion of the operation member and the concave portion of the rotation member face each other, and a pressing operation of the operation member is allowed. When not in the horizontal state, there is no proposal for a cover opening / closing safety device for a CD player configured such that a pressing operation of the operating element is not allowed because a shaft portion of the operating element does not face a concave portion of the rotating member. It is assumed that.

[0005]

With the above construction, when the device is in a substantially horizontal state, the shaft of the operating member and the concave portion of the rotating member face each other,
The lid can be opened by allowing the pressing operation of the operating element, but when the device is not in the horizontal state, the shaft of the operating element does not face the concave portion of the rotating member, and the pressing operation of the operating element is permitted. Without being able to open the lid.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the appearance of a CD player to which the present invention is applied. In the figure, 1 is an equipment cabinet, 2 is a lid, 2a is an engagement recess provided in the lid,
Reference numeral 3 denotes an open / close button as an operator, and the open / close button 3 opens and closes the lid 2. Reference numeral 4 denotes a group of operation buttons for performing reproduction, stop, skip, etc., reference numeral 5 denotes a speaker, and reference numeral 6 denotes a carrying handle.

FIG. 2 is a sectional side view of a main part showing the structure of the lid opening / closing safety device. In the figure, reference numeral 3a denotes a shaft portion provided integrally with the open / close button 3, and 7 denotes a lock lever as an engagement member. The lock lever 7 includes an operating arm portion 7a, an engagement claw 7b, and a rotation shaft 7.
c, the spring part 7d is integrally molded. The lock lever 7 is urged in the direction of arrow B by a spring portion 7d, and faces the hook portion 3b of the open / close button 3. It is assumed that the operation element 3 is urged in the direction of arrow A by a spring (not shown).

Reference numeral 8 denotes a stopper serving as a rotating member. The stopper 8 is rotatable about a rotating shaft 8a, and a recess 8b into which the shaft 3a of the operation element 3 can enter. Are provided, and a contact portion 8c is further provided. Reference numeral 9 denotes a metal weight attached to the stopper 8. Therefore, when the equipment cabinet 1 is in a substantially horizontal state (the state shown in FIG. 2), the shaft 3a of the operator 3
When the equipment cabinet 1 is not in a horizontal state (see FIG. 3), the shaft 3a of the operating element 3 and the contact portion 8c of the stopper 8 come into contact with each other. In addition, the stopper 8 rotates.

Next, the operation of the lid opening / closing safety device of the present invention will be described. First, when the equipment cabinet 1 is in a horizontal state (see FIG. 2), the shaft 3a of the operation unit 3 and the recess 8b of the stopper 8 face each other as described above, so that the operation unit 3 is pressed in the direction indicated by the arrow A. When operated, the shaft 3a of the operating element 3 enters the recess 8b of the stopper 8. Then, the operating arm 7a of the lock lever 7 is pressed by the hook 3b of the operation element 3, so that the lock lever 7 turns around the turning shaft 7c in the direction opposite to the arrow B. As a result, the lid 2
Is disengaged from the engagement recess 2a and the engagement claw 7b of the lock lever 7, and the lid 2 is opened. It is assumed that the lid 2 is urged in the opening direction by a spring (not shown).

On the other hand, when the equipment cabinet 1 is not in a horizontal state (see FIG. 3), the stopper 8 is rotated by the weight 9, so that the shaft portion 3a of the operating element 3 and the contact portion 8c of the stopper 8 face each other. Then, even if the operation element 3 is pressed in the direction of arrow C, the shaft 3a of the operation element 3 is
c. For this reason, the hook 3 of the operator 3
b cannot press the operating arm 7a of the lock lever 7, so that the engagement between the engagement recess 2a of the lid 2 and the engagement claw 7b of the lock lever 7 cannot be released, and the lid 2 will not open.

Therefore, even if the operation element 3 is pushed by hand or touched by the body when carrying the equipment, the operation element 3 is stopped by the stopper 8.
Is prevented.

[0012]

According to the present invention as described in detail above, according to the present invention, a cover having an engaging recess, an engaging claw engaging with the engaging recess of the cover and an operating arm portion. A mating member, an operator having a shaft inserted into the device and pressing the operating arm of the engaging member, and a concave portion into which the shaft of the operator enters, and a weight attached to one end. When the device is in a substantially horizontal state, the shaft portion of the operation member and the concave portion of the rotation member face each other, and the pressing operation of the operation member is allowed, and the device is moved horizontally. When not in the state, since the pressing portion of the operating element is not allowed because the shaft portion of the operating element and the concave portion of the rotating member do not face each other, the lid is opened when the device is carried, The CD does not pop out and is not damaged.
