Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a magnetic recording/reproducing device having a front rope inter-device provided with a safety device.

[Prior Art] Conventionally, the front panel of a front loading device can be freely opened and closed, and when a cassette is inserted, it opens, and a switch inside operates the cassette, so that the cassette is inked.

[Problem to be Solved by the Invention 1] In the conventional magnetic recording/reproducing device as described above, the front panel has a structure that can be opened and closed freely, making it easy to insert objects other than the cassette, especially a person's hand. However, due to its operation, it had the following drawbacks.

■When you insert your hand through the front panel, you may touch the switch inside and get your hand sucked inside, causing an unexpected injury.

■If a foreign object is inserted through the front panel, you may insert the cassette without knowing it, and the foreign object may damage the precision parts inside.

The present invention has been made in order to solve such conventional problems, and an object of the present invention is to provide a magnetic recording/reproducing device in which anything other than a cassette cannot be inserted into the front panel.

[Means for solving the problem] In order to achieve the above object, a magnetic recording/reproducing device having a front loading device is equipped with a switch, and a safety device is installed that prevents the device from accepting anything other than cassettes unless the switch is activated. It has a structure.

[Function] With the above configuration, the front panel is locked except when the cassette is inserted, so it is possible to prevent damage to the device due to foreign objects and injury to the hand caused by erroneous insertion.

[Example] Fig. 1 is a front view and a side view showing the relationship between the cassette and front loading in the magnetic recording/reproducing device of the present invention, and Fig. 2 is a side view showing the state after the cassette is inserted in Fig. 1. . In Figures 1 and 2, 1 is the front loading panel so that hands or objects cannot be inserted into it except during operation, 2 is the cassette detection piece that detects whether a cassette is inserted, and 3 is the cassette detection piece 2. 4 is a switch that operates when the front loading panel 1 is actuated;
5 is a motor for opening and closing the front loading panel l, and 6 is a cassette.

The operation of the present invention will be explained below with reference to the drawings.

Normally, when the cassette 6 is not inserted, the front loading panel 1 is locked by the ohmic gear 4b and does not open or close (Fig. 1).

state A in Figure 2). Next, when the cassette 6 is inserted, when both the cassette detection tabs 2 are activated, both the left and right switches 3 are turned on. Then, the motor 5 operates to open the front loading panel l via the transmission gear train 4 (the state shown in FIGS. 1 and 2B). Next, when the cassette 6 reaches a predetermined position, the motor 5 operates in a direction to close the front loading panel 1 (the state shown in FIG. 2A). At this time, as shown in FIG.
By transmitting force to b, it moves from B to A in FIGS. 1 and 2. However, the front loading panel is in state A, and the motor 5 is stopped, so a lock is exerted between the ohm gear 4b and the ohm 4a, and the front loading panel is not moved by an external force.

As mentioned above, this device has a structure that prevents anything other than the cassette 6 (hands, toys, etc.) from being inserted from the outside under any circumstances.

[Effects of the Invention] As explained above, the present invention has a structure that prevents anything other than the cassette from being carelessly inserted into the cassette insertion area, which prevents the user from accidentally inserting his or her hand into the device and damaging it or damaging the device. It is very effective from a safety point of view.
