According to a fourth aspect of the present invention, there is provided a recording medium information device, comprising: a holder capable of accommodating and moving the recording medium to guide the recording medium from a loading position; An operating member to be obtained, an erroneous loading detection member for detecting erroneous loading of the recording medium and preventing movement of the operating member with respect to the holder when the recording medium is erroneously loaded, and a holder extending in a direction intersecting the moving direction of the holder. A first guide formed on the actuating member and a first guide formed on the first member.
An intersection extending in a direction intersecting the guide of
A second guide having a continuous parallel portion extending in parallel with the first guide, simultaneously engaging the first guide and the second guide, and moving by being guided from the parallel portion of the second guide to the intersection. Accordingly, there is provided a stopper member capable of moving the operation member with respect to the holder, and an elastic member for urging the operation member toward the recording medium.

The operation of the recording medium information device according to claim 1 will be described below. When the recording medium comes in contact with the operating member, the operating member moves with respect to the holder that stores the recording medium, and the locking of the stopper member by the operating member is released with the movement of the operating member. Therefore, the holder with which the stopper member is engaged can be moved, and the holder moves while guiding the recording medium to load the recording medium at the loading position.

However, when the recording medium is erroneously loaded, the erroneous loading detecting member detects the erroneous loading of the recording medium and prevents the movement of the operating member with respect to the holder, so that the locking of the stopper member by the operating member is not released. This prevents the recording medium from being loaded at the loading position.

Therefore, the erroneous loading detection member detects the erroneous loading of the recording medium such as inserting the recording medium from the wrong direction, and prevents the movement of the operating member with respect to the holder. There is no danger of doing so.

The operation of the recording medium information device according to claim 2 will be described below. The stopper member simultaneously engages with the first guide formed on the holder and the second guide formed on the operating member so as to extend in a direction intersecting the moving direction of the holder.

When the recording medium comes into contact with the operating member, the operating member moves with respect to the holder for storing the recording medium, and intersects the first guide with the movement of the operating member. The stopper member moves while being guided from the intersection of the second guide extending in the direction to the parallel portion of the second guide extending in parallel with the first guide.

As a result, the stopper member can move along the parallel portion of the first guide and the second guide, and accordingly, the holder for guiding the recording medium moves, and the recording medium moves to the loading position. Is loaded.

However, when the recording medium is erroneously loaded, the erroneous loading detection member detects the erroneous loading of the recording medium, and prevents the movement of the operating member with respect to the holder, so that the recording medium is not loaded at the loading position.

Accordingly, similarly to the first aspect, the erroneous loading detection member detects erroneous loading of the recording medium such that the recording medium is inserted from an incorrect direction, and prevents the movement of the operating member with respect to the holder. There is no danger that the information device will malfunction when loaded.

The operation of the recording medium information device according to claim 3 will be described below. The stopper member simultaneously engages with the first guide formed on the holder and the second guide formed on the operating member so as to extend in a direction intersecting the moving direction of the holder.

When the recording medium comes into contact with the operating member, the operating member moves with respect to the holder for accommodating the recording medium, and is rotatably supported by the operating member with the movement of the operating member. The misloading detecting member is guided by the groove formed in the holder and rotates.

Further, in a state where the operating member moves with respect to the holder and the misloading detecting member is rotated, the second guide extends from the intersection of the second guide and the second guide extending in the direction intersecting the first guide. The stopper member moves while being guided by the parallel portion of the second guide extending parallel to the first guide.

As a result, the stopper member can move along the parallel portions of the first guide and the second guide, and the movement of the stopper member is detected, and the drive source starts driving to guide the recording medium. The holder is moved by the driving force of the driving source to load the recording medium at the loading position.

However, when the recording medium is erroneously loaded, the erroneous loading detection member detects the erroneous loading of the recording medium based on the presence or absence of the rotation operation, and prevents the movement of the operating member with respect to the holder. Since the recording medium does not move, the recording medium is not loaded at the loading position.

Therefore, similarly to the first aspect, the erroneous loading detection member detects erroneous loading of the recording medium such that the recording medium is inserted from an incorrect direction, and prevents the movement of the operating member with respect to the holder. As a result of not detecting the movement of the member, the drive source is not started to be driven, so that there is no possibility that the information device malfunctions at the time of erroneous loading.

The operation of the recording medium information device according to claim 4 will be described below. Also in this aspect, when the recording medium is erroneously loaded, the erroneous loading detecting member detects the erroneous loading of the recording medium and prevents the movement of the operating member with respect to the holder, as in the first to third aspects.

On the other hand, an operating member capable of contacting the recording medium is relatively movable with respect to a holder capable of moving and guiding the recording medium from the loading position, and the elastic member biases the operating member toward the recording medium. I do.

Further, the stopper member simultaneously engages with the first guide formed on the holder and the second guide formed on the operating member so as to extend in a direction intersecting the moving direction of the holder. At the time of ejection of the recording medium, from the parallel portion of the second guide extending parallel to the first guide,
When the stopper member moves while being guided at the intersection of the second guide extending in the direction intersecting with the first guide, the operating member can move with respect to the holder.

Therefore, similarly to the first aspect, not only is there a possibility that the information device will malfunction when the device is erroneously loaded, but also when the recording medium is discharged from the information device, the operating member is urged toward the recording medium by the elastic member. As the operating member moves, the recording medium is ejected from the information device while having an appropriate momentum.

That is, since the recording medium is ejected from the information device using the operating member which is prevented from moving when the recording medium is erroneously loaded, there is no need to provide a separate member for ejecting the recording medium. Also, the manufacturing cost of information equipment has been reduced.
