[0009]

The first prior art shown in FIG. 13 requires an electronic component such as the electromagnetic plunger 16 to complicate the structure.
There is a problem such as a load on a processing circuit for controlling the driving and noise generation.

In the second prior art shown in FIG. 14, when the cassette tape 32 is ejected, the cassette tape 32 has to push up the door member 25, so that the recording / reproducing position of the cassette tape 32 is changed. Can be set only in the range in which it comes into contact with the door member 25. In this case, the door member 25 cannot be closed completely, and there is a problem that dust and the like enter. However, it cannot be used for a device that requires, and there is a problem that the range of use is narrowed.

An object of the present invention is to provide a door device of an electronic device which has a simple and low-cost structure which does not require an electromagnetic plunger and can be used for a wide range of electronic devices.

[0012]

According to the present invention, there is provided a door device at an insertion port of a recording medium formed in a housing of an electronic apparatus, wherein the door apparatus faces a conveyance path of the recording medium connected to the insertion port and is arranged in a direction in which the recording medium is inserted. A door member having a first guide slope gently inclined with respect to the first guide slope and a second guide slope gently inclined with respect to the discharge direction; Is a door device for an electronic device, comprising: an elastic member that is supported so as to be capable of projecting or retracting in a substantially vertical direction, and that generates an elastic force in the projecting direction.

In the door member according to the present invention, a first guide piece and a second guide piece forming the first guide slope and the second guide slope are connected to each other at a protruding end of the door member. A holding piece which is formed in a chevron shape and extends in a direction perpendicular to the inserting direction and the discharging direction and which sandwiches the elastic member is formed at a retreating side end of the first guide piece and the second guide piece. And

Still further, the door member of the present invention includes a first guide slope and a second guide slope, respectively.
A guide piece and a second guide piece are formed in a mountain shape mutually connected at a protruding side end of the door member, and the insertion direction and the discharge direction are from the retreat side ends of the first guide piece and the second guide piece. Is characterized in that a pressing piece extending in a direction parallel to is formed.

Further, the present invention provides the first guide piece and the second guide piece.
A projection is formed on each of both side surfaces of the guide piece to be in contact with both side walls of the transport path.

[0016]

According to the present invention, an insertion slot is provided in a housing of an electronic apparatus, and a recording medium such as a magnetic tape cassette is inserted and ejected from the insertion slot. A door member for opening and closing the insertion port is provided on the conveyance path of the recording medium connected to the insertion port so as to be able to protrude and retreat in a direction substantially perpendicular to the insertion direction and the discharge direction of the recording medium. The door member has a first guide slope inclined gently with respect to the recording medium insertion direction and a second guide slope inclined gently with respect to the discharge direction, facing the transport path.

The door member is supported by an elastic member such as sponge or rubber. This elastic member expands and contracts,
When the insertion port is to be closed, the door member is supported at a protruding position with respect to the recording medium conveyance path, and when the insertion port is to be opened, the door member is supported at the retracted position. When the recording medium is inserted, the recording medium inserted along the conveyance path connected to the insertion port presses the first guide slope. The pressing force of the recording medium parallel to the insertion direction is dispersed into a force parallel to the insertion direction and a force substantially perpendicular to the insertion direction due to the gentle inclination of the first guide slope. Therefore, the door member is pressed down in the retreating direction against the elastic force of the elastic member to compress the elastic member,
As a result, the door is retracted, and the recording medium can be inserted. When the recording medium passes over the door member, the door member is pushed up to the projecting position by the elastic force of the elastic member, and the insertion port is closed. When discharging the recording medium, the recording medium presses the second guide slope of the door member, whereby the door member is retracted, and the recording medium can be discharged.

In such a door device, even when a recording medium such as a magnetic tape is loaded at a predetermined loading position in the device for reproduction and recording, the door member is completely closed to prevent entry of dust and the like. Therefore, the present invention can be suitably applied to electronic devices requiring high accuracy. In addition, since electronic components such as an electromagnetic plunger are not required, the load on the processing circuit can be reduced, the plunger noise can be eliminated, and the cost can be reduced.

Preferably, in order to reduce the weight and material cost of the door member, the first guide piece and the second guide piece forming the first guide slope and the second guide slope are respectively formed by projecting the door member. At the side end, they are formed in an interconnected chevron. Further, a holding piece extending in a direction perpendicular to the inserting direction and the discharging direction is formed at a retreating side end of the first guide piece and the second guide piece. Therefore, since the pair of holding pieces sandwich the elastic member therebetween, the elastic member can be securely fixed.

Still preferably, the elastic member is formed in a mountain shape by the first guide piece and the second guide piece.
From the retreat side ends of the first guide piece and the second guide piece,
A pressing piece extending in a direction parallel to the insertion direction and the discharge direction is formed. Therefore, the end surface of the elastic member comes into contact with a large area, so that the elastic force of the elastic member can be reliably transmitted to the door member.

[0021] More preferably, protrusions are formed on both side surfaces of the first guide piece and the second guide piece, respectively, to contact the both side walls of the transport path. Therefore, the contact area between both side surfaces of the door member and both side walls of the transport path is reduced, and sliding resistance when the door member protrudes and retracts can be reduced.
