Abstract

PURPOSE:To provide an eject device for a DCP mechanism capable of automatically setting a mode for ejecting a recording medium when an operation part is disconnected from a main body as requested by a user. CONSTITUTION:In an eject device of the invention, an eject mode for ejecting a recording medium when a power is switched OFF beforehand is registered in a RAM 31 by using an operation key. Thus, when an engine key switch 33 is OFF, based on a medium detecting switch 20 and the eject mode set in the RAM 31, a microcomputer 30 controls a cassette mechanism 16 and the recording medium in a main body 1 is automatically ejected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ejecting device of a DCP mechanism in which a recording medium is inserted into an insertion opening of a case-shaped main body and an operation section is detachably provided on a front surface of the main body.

[0002]

2. Description of the Related Art When a recording medium reproducing device such as a cassette tape player is mounted on a moving body such as an automobile and the vehicle is left, a part of the device, for example, an operating portion (operation) is used to prevent the recording medium reproducing device from being stolen. A DCP mechanism is known in which a panel is removed to make it portable.

As an example of this DCP opening / closing mechanism, a cabinet is installed in a space such as a dashboard of an automobile, the cabinet is used as a main body, and a cassette tape insertion opening is formed in the front portion of the main body. A structure is known in which the outer lid portion is detachably attached to the inner lid portion. Here, the inner lid part is rotatably attached to the cabinet, which is the main body, and the cassette tape insertion opening is openable and closable, and the outer lid part is configured as an operating part. It is provided and is detachably attached to the inner lid portion.

Here, in order to remove the outer lid portion which is the operation portion with the inner lid portion integrally attached to the outer lid portion being attached to the main body, the door open switch on the front surface of the outer lid body is operated. By this, a rotation starter such as a motor is activated, and the inner lid part is opened together with the outer lid part by rotating with respect to the main body. Subsequently, by removing the outer lid body from the inner lid body in this state, the outer lid portion, which is the operation portion, can be carried. After this, the inner lid part from which the outer lid part has been removed is again rotated to the original position and mounted on the main body. The reason why the inner lid is reattached to the main body in this manner is to ensure mechanical strength and safety against impact when the removed outer lid is reattached.

As another example of the DCP opening / closing mechanism, the outer lid, which is the operating portion, can be removed from the inner lid without the inner lid being configured to be rotatable with respect to the main body as in the structure of the above example. The structure made into is also known.

[0006]

By the way, the conventional DC
In the P opening / closing mechanism, there is a problem that the eject operation cannot be performed and the recording medium cannot be ejected from the main body when the outer lid body that is the operation unit is removed. In order to solve this problem, it may be possible to eject the recording medium even after the operation unit is removed, but a new problem arises, such as a new eject switch.

The present invention has been made in view of the above problems, and an ejector of a DCP mechanism capable of setting a mode for automatically ejecting a recording medium when an operating portion is removed from the case according to a user's request. The purpose is to provide a device.

[0008]

In order to achieve the above object, an ejecting device of a DCP mechanism of the present invention sets or registers a mode for ejecting a recording medium when a special state is detected based on a predetermined operation. And an eject setting means for releasing the operation unit, a first detecting means for detecting that the operation section is removed from the main body, and a second detecting means for detecting that the recording medium is loaded in the main body.
It is determined that the special state is based on the detection means, the first detection means, and the second detection means, and the loading / ejection mechanism is driven based on the determination and the ejection setting means. The gist is that the control means for ejecting the recording medium is provided.

The state of the switch 3b, the engine key switch 33 for detecting power on / off, and the operation key 3d provided on the operation unit 3 is monitored, and control described later is performed. RAM31
Is a rewritable memory for storing or canceling registration of the eject setting mode based on the operation of the operation key 3d.
The cassette mechanism 16 includes a cassette tape loading / ejecting mechanism, and the display 3c is provided on the front surface of the operation unit 3. + B is a backup power supply and is always supplied with power.

First, the eject setting mode registration process will be described with reference to FIG. When the predetermined operation of the operation keys 3d, for example, the double operation of the stop button and the fast-forward button is judged in the ON state of the main body 1 (S10) and the eject setting operation is performed, the RAM 31 is collated and the eject mode is already set. It is determined whether or not it has been performed (S11). If the eject mode has already been set, the eject mode is released. If the eject mode has not been set, the eject mode setting is stored in the RAM (S12, S13).

Next, an embodiment of the eject process will be described with reference to FIG. First, when the engine key switch 33 is turned off, it is determined by the DCP switch 3b whether DCP is present in the operation unit holder (S1).
4). If the operation unit 3 is still attached, a low power consumption mode is entered in which most of the main body is turned off, leaving some power supply (S15). On the contrary, if the operation unit 3 is removed, the RAM 3
It is determined whether or not the eject setting is set to 1 (S
16) If it is not set, the process proceeds to (S15). If it is set, it is determined by the medium detection switch 20 whether the cassette tape 18 is in the main body 1 (S17). If there is, the cassette mechanism 16 is driven. Then, the cassette tape is ejected (S18).

FIG. 13 shows another embodiment of the eject process. The engine key switch 33 is not judged, but the DCP switch 3b first judges whether or not the operation portion is removed (S19). If the operation unit 3 is removed, it is similarly determined whether the cassette tape 18 is present in the main body (S20).
If so, it is determined whether or not the eject setting is made in the RAM 31 (S21). If it is set, the cassette mechanism 16 is driven to eject the cassette tape (S22).
