Description

Technical Field

[0001] This utility model relates to the field of audio playback device technology, and in particular to a magnetic tape player with anti-accidental erasure function. Background Technology

[0002] Tape players have been widely used for a long time, and their small size, light weight, portability, and ease of use have made them popular with many users. Current tapes generally have an anti-erasing plate on the bottom of the casing, which blocks the anti-erasing hole on the tape, allowing for easy and repeated recording. To save the recorded content and prevent accidental erasure, simply remove the anti-erasing plate to expose the anti-erasing hole. However, due to the large size of traditional tape players, their anti-erasing devices are also large and complex, making them inconvenient to fit into portable small tape players that are four to five centimeters thick. This results in the lack of anti-erasing functionality in portable small tape players, affecting the user experience. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a tape player with anti-accidental erasure function that is simple in structure, reasonable in design, compact and practical in anti-accidental erasure mechanism, and perfectly applicable to portable small tape players.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a tape player with anti-mist erasure function, including a housing, a mechanism, a speaker, and control buttons. The mechanism is provided with a recording / playback head, an erasure head, and an anti-mist erasure control rod, which is connected to the recording button in the control buttons. It also includes an anti-mist erasure control component, the two arms of which form a V-shaped structure, and a mounting hole is provided at the corner where the two arms intersect. A fixing post is provided in the housing, and the anti-mist erasure control component is pivotally mounted by the fixing post through the mounting hole. A torsion spring is provided on the anti-mist erasure control component, and the torsion spring drives the anti-mist erasure control component to rotate to a locked protection position where one of its arms is facing the bottom of the anti-mist erasure control rod. The other arm of the anti-mist erasure control component is provided with a forward-extending control foot, and a through hole is provided at the bottom of the tape slot in the housing. The control foot extends out of the tape slot through the through hole so as to be opposite the anti-mist erasure hole of the tape.

[0005] Furthermore, an upward-protruding hook is provided at the front end of the control foot. After the magnetic tape is inserted into the magnetic tape slot, the hook is engaged in the anti-erasure hole of the magnetic tape or pressed down by the anti-erasure piece in the anti-erasure hole. After the hook is pressed down by the anti-erasure piece of the magnetic tape, it drives the anti-erasure control component to rotate to a position that is offset from the bottom end of the anti-erasure control rod.

[0006] Preferably, the angle of the V-shaped angle formed by the two arms of the anti-accidental wiping control component is an obtuse angle.

[0007] Furthermore, the control foot extends forward from the bottom of the support arm below the anti-accidental wiping control component.

[0008] As a better option, the included angle formed by the two arms of the anti-accidental wiping control component is 120-150 degrees.

[0009] Furthermore, a rearwardly extending shaft tube is formed at the corner where the two arms of the anti-accidental wiping control unit intersect, and a mounting hole is located in the shaft tube; a torsion spring is sleeved on the shaft tube, one end of the torsion spring is locked onto the arm on the anti-accidental wiping control unit, and the other end is connected and fixed to the housing.

[0010] Furthermore, the shaft tube, the two support arms of the anti-accidental wiping control component, and the control feet are integrated into a single structure, and are made of plastic material through injection molding.

[0011] This invention features a V-shaped anti-mist erasure control component located beneath the core mechanism within the housing. This component works in conjunction with an anti-mist erasure control lever on the core mechanism, with the control foot extending out of the tape slot. When a tape with an anti-mist erasure tab is inserted, the tab presses down the control foot, causing the anti-mist erasure control component and lever to be misaligned. This allows the record button to be pressed, enabling erasure of the tape via the erasure head. When a tape without the anti-mist erasure tab is inserted, the control foot is not pressed down, aligning the anti-mist erasure control component and lever and preventing the record button from being pressed, thus preventing erasure. The entire device is compact, practical, and easy to install, making it suitable for use in small, portable tape players only four to five centimeters thick. Attached Figure Description

Detailed Implementation

[0019] In this embodiment, refer to Figures 1-6 The tape player with anti-erase function is a small, portable tape player, 4-6 cm thick, comprising a housing 1, a mechanism 2, a speaker, and control buttons. The housing 1 has a front cover 11 to cover the tape slot 12. The mechanism 2 is equipped with a recording / playback head, an erase head 21, and an anti-erase control lever 22, which is connected to the recording button 4 in the control buttons. It also includes an anti-erase control component 3, whose two arms form a V-shaped structure (or a figure-7-like structure), and a mounting hole is provided at the corner where the two arms intersect. A fixing post 13 is provided in the middle, and the fixing post 13 passes through the mounting hole to realize the pivotal installation of the anti-accidental erasure control component 3, so that the anti-accidental erasure control component 3 can rotate; a torsion spring (the torsion spring is a conventional existing technology and is not shown) is provided on the anti-accidental erasure control component 3, and the torsion spring drives the anti-accidental erasure control component 3 to rotate to the locking protection position where one of its arms is directly opposite the bottom end of the anti-accidental erasure control rod 22; the other arm of the anti-accidental erasure control component 3 is provided with a control foot 31 extending forward, and a through hole 14 is provided at the bottom of the magnetic tape slot 12 of the housing 1, through which the control foot 31 extends out into the magnetic tape slot 12 so as to be opposite to the anti-erasure hole of the magnetic tape 5.

[0020] A hook protruding upwards is provided at the front end of the control foot 31. After the magnetic tape 5 is inserted into the magnetic tape slot 12, the hook is engaged in the anti-smear hole of the magnetic tape 5 or pressed down by the anti-smear plate in the anti-smear hole. After the hook is pressed down by the anti-smear plate of the magnetic tape 5, it drives the anti-smear control component 3 to rotate to a position that is offset from the bottom end of the anti-smear control rod 2.

[0021] Specifically, for tapes that require recording, the anti-erasure tab is retained. After the tape is inserted, the anti-erasure tab presses down on control foot 31, causing the anti-erasure control element 3 to rotate and thus be misaligned with the anti-erasure control lever 2. At this time, the record button 4 can be pressed to erase the tape 5. For tapes 5 that do not require recording, the anti-erasure tab can be removed. After the tape 5 is inserted into the tape slot 12, control foot 31 is not pressed down, and the anti-erasure control element 3 is positioned directly opposite the bottom of the anti-erasure control lever 2. In this case, pressing the record button 4 will not be possible because the anti-erasure control lever 22 is blocked by the anti-erasure control element 3, thus preventing the erasure of the tape 5 and fulfilling the anti-erasure function.

[0022] The angle of the V-shaped angle formed by the two arms of the anti-accidental wiping control component 3 is an obtuse angle, which can be 120-150 degrees, such as 140 degrees.

[0023] The control foot 31 extends forward from the bottom of the support arm below the anti-accidental erasure control component 3 so as to contact the bottom surface of the magnetic tape 5.

[0024] A rearwardly extending shaft tube is formed at the corner where the two arms of the anti-miswiping control component 3 intersect, and the mounting hole is located in the shaft tube; a torsion spring is sleeved on the shaft tube, one end of the torsion spring is locked onto the arm on the anti-miswiping control component 3, and the other end is connected and fixed to the housing 1 so that the anti-miswiping control component 3 can be kept aligned with the anti-miswiping control rod 2 by its elastic force.

[0025] The shaft tube, the two support arms of the anti-accidental wiping control component 33, and the control foot 1 are an integral structure, which is made of plastic material by injection molding.

[0026] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of this application. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
