Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cassette tape ejecting device.

Structure of a conventional example and its problems FIGS. 1A and 1B are a plan view and a side view of a conventional cassette tape ejector. In the figure, 1
is a cassette tape, 2 is a boss located on the front side of the cassette tape, 3 is a boss located on the rear side of the cassette tape 1, 4 is a leaf spring that presses the cassette tape,
5 is a cassette tape eject arm, and 6 is an eject button.

Next, the operation of the above-mentioned conventional cassette tape ejector will be explained. Conventionally, most of these types of devices either open the door and then press the eject button 6 to eject the cassette tape 1, or when the eject button 6 is pressed, the door and the cassette tape 1 are ejected at the same time. Some items can be taken out by hand after opening the door.

However, adding an eject mechanism increases the cost and further requires space for the eject button 6 and its mechanism. Furthermore, even in a structure in which the tape can be taken out by hand, the cassette tape cannot be taken out unless there is a space outside the cassette tape where the hand can be inserted, so extra space must be provided separately. Also, with such a structure,
Since the cassette tape can be forcibly removed while the cassette tape is in operation, there is also a problem with the safety of the equipment.

Purpose of the Invention The present invention aims to eliminate the above-mentioned drawbacks of the conventional technology, and instead of using an eject button, it is possible to easily eject the cassette tape by pressing it with a fingertip, etc., and to prevent the cassette tape from being ejected while it is in operation. An object of the present invention is to provide a cassette tape ejecting device that can perform the following operations.

Structure of the Invention In order to achieve the above object, the present invention is configured so that the cassette tape can be easily ejected without providing an additional ejecting mechanism, and by providing a lever that regulates the rear end surface in conjunction with the movement of the head. , the cassette tape cannot be ejected even if the rear end is pressed during operation.

DESCRIPTION OF EMBODIMENTS The configuration of an embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 2A and B and FIG. 3, 21 is the cassette tape, 22 is the first boss located on the front side of the cassette tape 21, and 23 is the cassette tape 2.
1, a second boss located on the rear side of 1; 24, a presser plate spring for the cassette tape 21; 25, a part that ejects the cassette tape by pressing it with a fingertip or the like;
26 is a part that is pressed with a fingertip or the like when installing the cassette tape 21; 27 is a part that moves together with the magnetic head;
Further, a head moving plate locks a lever 28 on the rear end surface, 28 is a lever that controls the ejection of the cassette tape, 29 is a lever fulcrum, and 30 is a lever spring that pulls the lever in one direction.

Next, the operation of the above embodiment will be explained. The cassette tape 21 has a first boss 22 and a second boss 2.
3 and a presser plate spring 24 to restrict it to a predetermined position. Next, as shown in Fig. 3, the cassette tape 2
When the rear end surface 25 of 1 is pressed with a fingertip or the like, the second boss 2
The cassette tape 21 is removed from the first boss 22 using the fulcrum 3, and the cassette tape 21 can be easily taken out. Further, the cassette tape 21 can be easily attached by pressing the part 26 with a fingertip or the like.

Next, in Fig. 4A and B, cassette tape 2
1 is in operation, that is, when the head moving plate 27 moves, the lever 28 rotates about the lever fulcrum 29 overcoming the lever spring 30, and the fourth
The state shown in the figure will be reached. Even if part 25 is pushed in this state, it will hit the end face of lever 28 and cannot be ejected. When the head moving plate 27 returns to the standby position, the lever 28 is rotated by the lever spring 30 about the lever fulcrum 29, resulting in the state shown in FIG.

Effects of the Invention The present invention has the above-described configuration, and according to the present invention, a cassette tape can be easily set and ejected without additionally providing an ejecting mechanism, and therefore, it can be provided at low cost. Furthermore, in order to ensure the safety of the equipment when it is ejected during operation, it is possible to ensure the safety of the equipment by making it impossible to eject the equipment during operation.
