Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tape cassette with a lid suitable for high-density recording of digital audio, video, etc.

BACKGROUND OF THE INVENTION In recent years, there has been a trend toward higher density magnetic recording, and new digital audio cassettes have been proposed. One example is the tape cassette used in a rotating head type digital cassette recorder, which has an opening on the front and a bottom opening next to the front opening for pulling out the tape. , or a lid that closes these openings to prevent fingerprints from adhering to the tape.

An example of a proposed tape cassette with a lid will be described below with reference to the drawings.

FIG. 9 is a top view of the proposed tape cassette with a lid in a closed state, where 1 is the cassette body, 2 is a rotary lid that opens and closes the front opening, and is always biased in the closing direction. Figure @10 is a side view of the same, and 3 is a sliding lid that opens and closes the bottom opening, which is slidably provided on the outside of the bottom of the cassette body, and is normally biased in the closing direction, but it is not engaged in the two positions of opening and closing. It is locked by a stop means (not shown). Figure 11 is its front view.
4 is a notch provided in the rotating lid 2, into which the front end of the sliding lid 3 can be seen. 6 is a notch also provided in the rotating lid 2,
The unlocking portions of the sliding lid 3 in both the open and closed positions communicate with the viewing groove.

FIG. 12 is a side view showing a state in which the sliding lid 3 is opened and locked in the open position. FIG. 13 is a side view showing a state in which the rotary lid 2 is further opened. As you can see from the figure, the rotating lid 2
can be opened only after opening the sliding lid 3. 14th
The figure is a bottom view of each lid in the closed state.

Problems to be Solved by the Invention However, with the above configuration, when taking out the main cassette with the sliding lid open from the cassette holder, etc., there is a risk that the rear end of the left and right sides of the sliding lid may be grabbed and taken out. In this case, even if the sliding lid is unlocked in the open position, it will not remain in the open position and will be ejected with the sliding lid locked again. The problem was that there was a problem.

In view of the above-mentioned problems, the present invention prevents the left and right side rear ends of the sliding lid from being pinched when taking it out from a cassette holder etc. even when the sliding lid is locked in the open position, and also prevents the movable parts of the lid etc. To provide a tape cassette with a lid which is easy to take out by providing a wide grip area in other parts.

Means for Solving the Problems In order to solve the above problems, the present invention provides a telescope with a lid.
- The pouch set has a rotating lid that opens and closes the front opening, a sliding lid that opens and closes the bottom opening and is locked in both open and closed positions, and both sides of the sliding lid that extend vertically upward from the left and right ends of the sliding lid. , a notch provided at the rear end of both sides of the sliding lid.

Function: With the above-described configuration, the present invention can provide a wide grip area on parts other than the movable parts, such as the sliding lid, so that the sliding lid can be reliably closed when taken out from the cassette holder, etc. becomes 1.

□ ・1 Example Hereinafter, a tape cassette with a lid according to an example of the present invention will be described with reference to the drawings.

FIG. 1 is a bottom view of a tape cassette with a lid in a closed state in a first embodiment of the present invention. In Figure 1, 6
is the notch. FIG. 2 is a side view thereof, and FIG. 3 is a side view showing a state in which the sliding lid 3 is locked in the open position.

According to this embodiment configured as described above, even when the sliding lid 3 is opened, the notch 6 as shown in FIG. 3 makes it difficult to remove the sliding lid 3 from the cassette holder or the like. Since the cassette body 1 can be taken out by grasping the rear end of the cassette body 1 without having to grip the side surface, the sliding lid can be automatically closed after being unlocked to the open position during removal.

A second embodiment of the present invention will be described below with reference to the drawings.

FIG. 4 is a bottom view showing a lid closed state of a tape cassette with a lid showing a second embodiment of the present invention. In the figure, reference numeral 7 denotes a guide portion, which is formed at the rear of the bottom of the cassette main body to extend in the direction of movement of the sliding lid 3 and to be continuous with and approximately at the same height as the cassette support reference surface provided at the rear end of the cassette. Reference numeral 8 denotes both right and left ends of the bottom surface of the sliding lid 3 which are in contact with the notch 6 of the sliding lid 3, and when the sliding lid 3 is opened, they enter inside the guide portion 7 and regulate the left and right direction. FIG. 5 is a side view of the cassette, and reference numeral 9 denotes grip areas provided at the rear of both sides of the cassette body, which are formed on the same surface in the vertical direction of the cassette, and have an uneven surface to prevent fingers from slipping.

With this configuration, the grip area can be formed to be wide in the same plane in the vertical direction of the cassette body, so that the cassette can be taken out reliably without grasping the side surface of the sliding lid. Further, since the guide portion 7 can restrict and guide the displacement of the rear end portion of the sliding lid 3 in the left-right direction, smooth opening and closing can be achieved.

FIG. 7 is a top view of a third embodiment of the present invention, showing another embodiment in the grip area, and 10 is a recess provided in the grip area. FIG. 8 is a side view thereof. The concave portion 1o provided in the grip area can be used as a grip portion when transferring a cassette in a cassette autochanger or the like, or as a detection portion for preventing incorrect insertion of a tape cassette.

In the first embodiment, the notches 6 are provided at the left and right rear ends of the sliding plate 3;
Any structure may be used as long as the both sides do not come close to the rear end of the cassette body when the cassette body is opened.

Furthermore, the guidance provided by the guide portion 7 and both left and right ends 8 of the bottom surface of the sliding lid may not be guided during the opening and closing operations, but may be such that it is regulated when opening. Furthermore, instead of providing a pair of guide parts on the left and right sides, one guide part may be provided in the center, and a slit may be provided on the sliding lid side to sandwich the guide part.

Effects of the Invention As described above, the present invention includes a rotating lid that opens and closes a front opening;
A sliding lid that opens and closes the bottom opening and is locked in the open/closed position, both sides of the sliding lid that extend vertically upward from the left and right ends of the sliding lid, and notches provided at the rear ends of both sides of the sliding lid. By providing this, there is no risk of pinching the rear ends of both measuring parts of the sliding lid when taking out the tape cassette from the cassette holder etc. with the sliding lid locked in the open position. It is possible to ensure that the is in the closed state. Moreover, since the grip area can be formed wide, handling becomes easy.
