JPS6010448A - Cassette tape ejecting device - Google Patents

Abstract

PURPOSE:To make ejection of a cassette tape impossible when the rear end face is pushed during operation, by constituting a device so that the cassette tape is ejected easily without providing an ejecting mechanism and providing a lever which controls the rear end face in accordance with the movement of a head. CONSTITUTION:A cassette tape 21 is set in a prescribed position by the first boss 22, the second boss 23, and an auxiliary leaf spring 24. When a rear end face 25 of the cassette tape 21 is pushed with a finger or the like, the cassette tape 21 is detached from the first boss 22 with the second boss as a fulcrum and can be taken out easily. The cassette tape 21 is set easily by pushing a part 26 with a finger or the like. When the cassette tape 21 is operated, that is, a head moving plate 27 is moved, a lever 28 is turned around a lever fulcrum 29 against a spring 30 for lever, and a part 25 is brought into contact with the end face of the lever 28 and the cassette tape 21 cannot be ejected when the part 25 is pushed in this state.

Description

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

Structure of a conventional example and its problems FIG. 1 fAl, CB) are a plan view and a side view of a conventional cassette tape ejecting device. 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 plate spring that presses the cassette tape, 5 is a cassette tape eject arm, and 6 is an eject button.

Next, the operation of the conventional cassette tape ejecting device will be described. 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 are opened and then removed by hand.

However, adding an eject mechanism increases cost and further requires space to accommodate the eject button 6 and its mechanism. Even in the structure where 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. Furthermore, with such a structure, there is a problem with the safety of the equipment since the cassette tape can be forcibly removed while the cassette tape is in operation.

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

Structure of the Invention In order to achieve the above object, the present invention is configured so that two cassette tapes can be easily ejected without providing an eject mechanism, and a lever is provided to control the rear end surface in conjunction with the movement of the head. By the way, the cassette tape can no longer be ejected even if you press the rear edge while it is in operation.

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

In Figure 2 + AI, tB) and Figure 3, 21
is a cassette tape, 22 is a first boss located on the front side of the cassette tape 21, 23 is a second boss located on the rear side of the cassette tape 21, 24 is a presser plate spring for the cassette tape 21, and 25 is a cassette tape A part to be ejected by pressing with a fingertip or the like, 26 a part to press with a fingertip or the like when loading the cassette tape 21, 27 a head moving plate that moves together with the magnetic head and locks a lever 28 on the rear end surface, 28 a cassette A lever controls tape ejection, 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 is regulated at a predetermined position by a first boss 22, a second boss 23, and a presser plate spring 24. Next, as shown in FIG. 3, when the rear end surface 26 of the cassette tape 21 is pressed with a fingertip or the like, the cassette tape 2
1 is removed from the first boss 22, and the cassette tape 21 can be easily taken out. The cassette tape 21 can still be easily attached by pressing the part 26 with a fingertip or the like.

Next, in FIG. 4 (Al, CBI), when the cassette tape 21 is in operation, that is, when the head moving plate 27 moves, the lever 28 overcomes the lever spring 3o and rotates about the lever fulcrum 29. The state shown in Fig. 4 is reached.Even if you press the part 25 in this state, it hits the end face of the lever 28 and cannot be ejected.When the head moving plate 27 returns to the initial position, L//<-28tdv bar support A29
Rotate the lever spring 301C many times with the entire center
It will be in the state shown in the figure.

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 eject mechanism, and therefore, it can be provided at low cost. . Furthermore, in order to ensure the safety of the device when it is ejected during operation, it is possible to ensure the safety of the device by making it impossible to eject the device during operation.
